FIELD OF THE INVENTION

[0002] The present invention relates to thermoplastic containers comprising an integrated separating component, as well as methods for converting the thermoplastic containers from a three-dimensional configuration into a configuration for enhanced recyclability. Systems and methods involving the thermoplastic containers are also provided. The present invention also relates to a thermoplastic container comprising one or a plurality of integrated separating components to irreversibly separate the container into component parts of a predetermined configuration.

BACKGROUND OF THE INVENTION

[0003] In November of 2018, the body of a dead sperm whale washed ashore on a beach in southern Indonesia. Daniel Victor, 1, 000 Pieces of Plastic Found Inside Dead Whale in Indonesia, N.Y. TIMES, Nov. 21, 2018, available at https://www.nytimes.com/2018/l l/21/world/asia/whale-plastics- indonesia.html. Inside the whale’s stomach, volunteers from the World Wildlife Fund in Indonesia found 13 pounds of plastic trash, including 115 plastic cups, four plastic bottles, 25 plastic bags, two plastic flip-flops, and hundreds of miscellaneous pieces of plastic debris. Id. While the exact cause of the whale’s death could not be determined, the large amount of undigestible plastic in its stomach certainly seems to have been a contributing factor. Similar stories are emerging across the globe: in June of 2018, a dead whale was found in Thailand, having nearly 18 pounds of plastic trash in its stomach; in Spain, a dead whale was found to have 64 pounds of trash clogging its intestines. Id.

[0004] In 2010, the top six plastic waste producers were all countries in Southeast Asia: China, Indonesia, the Philippines, Vietnam, Sri Lanka and Thailand; with the majority of the plastic waste coming in the form of single-use items that do not decompose, such as plastic bags, food packaging, straws, and cutlery. Id. While many countries are introducing legislation geared toward reducing plastic waste, the global scale of the epidemic presents a staggering challenge, particularly in economically disadvantaged populations. There is an urgent and alarming need for containers with enhanced recyclability that can address this world-wide crisis.

Thermoplastic Containers

[00074] Aspects of the invention include thermoplastic containers comprising: a base having a perimeter and one or a plurality of edges along said perimeter and one or a plurality of wall segments extending from the one or plurality of edges of said base. The container further includes one or a plurality of integrated separating components to irreversibly separate the container into component parts of a predetermined configuration.

[00075] Accordingly, thermoplastic containers in accordance with embodiments of the invention may have an initial geometry that defines the container, and then upon irreversible separation of the container into component parts of a predetermined configuration, the component parts are such that they facilitate the ability to recycle. For example, in some embodiments, the predetermined configuration and the component parts are such that they can pack together more efficiently and/or provide a configuration that facilitates feeding of the components into a recycling operation, as compared to the initial container geometry. Such recycling operation includes, but is not limited to, feeding one or more of the component parts into a granulator and/or feeding one or more of the component parts directly into a feed throat of an extruder and/or an injection molding machine. It is further contemplated that the predetermined configuration is one that allows for relatively more efficient shipping/storing from the perspective that one or more of the component parts of the predetermined configuration will define a relatively lower volume than what would otherwise be required when shipping/storing the thermoplastic container in its initial geometry.

[00076] Aspects of the invention include thermoplastic containers that are configured to preferably adopt a substantially flat configuration via the use of a separating component. Thermoplastic containers in accordance with embodiments of the invention generally comprise a base having a plurality of edges. Bases in accordance with embodiments of the invention can have any suitable size and thickness. For example, in some embodiments, a base has a dimension that ranges from about 1 mm up to about 2 m, such as about 2, 3, 4, 5, 6, 7, 8, or 9 mm, or about 1, 2, 3, 4, 5, 6, 7, 8, or about 9 cm, or about 1, 2, 3, 4, 5, 6, 7, 8, or 9 dm, or about 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, or 1.9 m. Bases in accordance with embodiments of the invention can have a thickness that ranges from about 0.01 mm to about 5 cm, such as about 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, or 0.09 mm, such as about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, or 0.9 mm, such as about 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, or 1.9 mm, such as about 2, 3, 4, 5, 6, 7, 8, or 9 mm, such as about 1, 2, 3, or 4 cm.

[00077] Bases in accordance with embodiments of the invention can have any suitable shape, having any number of edges. For example, in some embodiments, a base has a triangular shape, with three edges. In some embodiments, a base has a square shape, with four edges. In some embodiments, a base has a pentagonal shape, with five edges. In some embodiments, a base has a hexagonal shape, with six edges. As the number of edges of the base increases, the base approaches an approximately round, or circular geometry. For the avoidance of doubt, the term“plurality of wall segments”, as used herein, encompasses an embodiment wherein a base and/or a lid of a subject thermoplastic container comprises a round or oval geometry, and wherein the container comprises a wall segment that extends along the circumference of the round or oval geometry. Those of skill in the art will readily appreciate that a base or lid having any suitable number of edges, and any suitable shape, can be utilized in accordance with embodiments of the invention. In some embodiments, a base can comprise one or more folds, or fold lines, where the material of the base can be folded to provide enhanced mechanical properties to the container, or for aesthetic design purposes.

[00078] Thermoplastic containers in accordance with embodiments of the invention generally comprise a plurality of wall segments, equal in number to the number of edges on the base. As noted herein, where a base and/or a lid of a subject thermoplastic container comprises a round or oval geometry, the thermoplastic container can comprise a wall segment that extends along the circumference of the round or oval geometry. For the avoidance of doubt, such an embodiment is deemed to comprise a plurality of wall segments.

[00079] Wall segments in accordance with embodiments of the invention can have any suitable size and thickness, and are generally disposed in an orthogonal orientation with respect to the base in order to form the walls, or sides, of a thermoplastic container. Wall segments in accordance with embodiments of the invention are preferably square or rectangular in shape, but may also include other suitable geometries, depending on the design of a particular thermoplastic container. In some embodiments, a wall segment can comprise one or more ridges, indentations, or other features that provide desirable properties to the container, including, but not limited to, increased friction and graspability. In some embodiments, a wall segment can comprise one or more folds, or fold lines, where the material of the wall segment can be folded to provide enhanced mechanical properties to the container, or for aesthetic design purposes.

[00080] In some embodiments, a wall segment has a dimension that ranges from about 1 mm up to about

2 m, such as about 2, 3, 4, 5, 6, 7, 8, or 9 mm, or about 1, 2, 3, 4, 5, 6, 7, 8, or about 9 cm, or about 1, 2, 3, 4, 5, 6, 7, 8, or 9 dm, or about 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, or 1.9 m. Wall segments in accordance with embodiments of the invention can have a thickness that ranges from about 0.01 mm to about 5 cm, such as about 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, or 0.09 mm, such as about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, or 0.9 mm, such as about 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, or 1.9 mm, such as about 2, 3, 4, 5, 6, 7, 8, or 9 mm, such as about 1, 2, 3, or 4 cm.

[00081] Thermoplastic containers in accordance with embodiments of the invention can utilize any suitable combination of base dimensions and wall segment dimensions to form a container having a desired size and internal volume. For example, in some embodiments, a base has a larger dimension than the height of the wall segments, forming a container that is wider than it is tall. In other embodiments, a base has smaller dimensions than the height of the wall segments, forming a container that is taller than it is wide. In some embodiments, a base has a dimension that is the same as the height of the wall segments, thereby forming a container that is as wide as it is tall.

[00082] In some embodiments, a thermoplastic container comprises a lid. Lids in accordance with embodiments of the invention can have any suitable size and thickness, and are preferably disposed in an orthogonal position with respect to the wall segments in order to form a lid for a thermoplastic container. Lids in accordance with embodiments of the invention preferably have a geometry that closely mirrors the base of the thermoplastic container, depending on the design of a particular thermoplastic container. As the number of edges of the lid increases, the lid approaches an approximately round, or circular geometry. For the avoidance of doubt, the term“plurality of wall segments”, as used herein, encompasses an embodiment wherein a base and/or a lid of a subject thermoplastic container comprises a round or oval geometry, and where the container comprises a wall segment that extends along the circumference of the round or oval geometry. Those of skill in the art will readily appreciate that a base or lid having any suitable number of edges, and any suitable shape, can be utilized in accordance with embodiments of the invention. In some embodiments, a lid can comprise one or more folds, or fold lines, where the material of the lid can be folded to provide enhanced mechanical properties to the container, or for aesthetic design purposes.

[00083] In some embodiments, a lid has a dimension that ranges from about 1 mm up to about 2 m, such as about 2, 3, 4, 5, 6, 7, 8, or 9 mm, or about 1, 2, 3, 4, 5, 6, 7, 8, or about 9 cm, or about 1, 2, 3, 4, 5, 6, 7, 8, or 9 dm, or about 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, or 1.9 m. Lids in accordance with embodiments of the invention can have a thickness that ranges from about 0.01 mm to about 5 cm, such as about 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, or 0.09 mm, such as about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, or 0.9 mm, such as about 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, or 1.9 mm, such as about 2, 3, 4, 5, 6, 7, 8, or 9 mm, such as about 1, 2, 3, or 4 cm. In some embodiments, a lid can comprise one or more folds, or fold lines, where the material of the lid can be folded to provide enhanced mechanical properties to the container, and/or for aesthetic design purposes.

[00084] Lids in accordance with embodiments of the invention can be integrated with the thermoplastic container, for example, along one or all edges of the lid, or along at least a portion of one edge of the lid, so as to form a hinge that allows the lid to articulate between an opened and closed position with respect to the container. In some embodiments, a lid is completely separate from the thermoplastic container. Non-limiting examples of lid types include flush-type lids and plug-type lids, for example, as described in U.S. Patent No. 3,301,464, the disclosure of which is herein incorporated by reference in its entirety. When such embodiments are employed, one or more wall segments of the thermoplastic container are suitably modified to facilitate engagement of the lid with the wall segments, as described, for example, in U.S. Patent No. 3,301,464.

[00085] In some embodiments, a lid comprises a proximal end and a distal end. In certain embodiments, a proximal end of the lid comprises different elements than the distal end of the lid. For example, in some embodiments, the proximal end of the lid closely mirrors the geometry of the base of the thermoplastic container, for example, having a number of edges that matches the number of wall segments. In certain embodiments, a distal end of the lid contains a closure element similar to that of a milk carton, wherein folds of the thermoplastic material are used to create a liquid-impermeable closure.

[00086] In some embodiments, the distal end of the lid can include a cap. Suitable caps are generally known in the art, and can include standard features, such as a disc-shaped body and a depending skirt that can optionally comprise threading. In such embodiments, the distal end of the lid is suitably modified to engage with the cap, for example, by containing receptive threading. Optionally, any suitable cap liner or cap seal can be included. For example, a foam pressure seal, a foil heat induction seal, a LIFT ‘N’ PEEL™ heat induction liner, or a foam cap liner can readily be incorporated. Furthermore, any suitable safety seals and/or tamper resistant bands can readily be incorporated into a cap and/or lid in accordance with embodiments of the invention.

[00087] Aspects of the invention include troughs (e.g., base troughs (located within a base, or at an intersection of a base and a wall segment), wall troughs (located within a wall segment, or at an intersection of two wall segments), lid troughs (located within a lid, or at an intersection of a lid and a wall segment) that can be used to facilitate separation of the various components of the thermoplastic containers in order to allow them to preferably adopt a substantially flat configuration. Troughs in accordance with embodiments of the invention generally have a height (the distance from the floor, or bottom, of the trough to the top of the trough), a width (the distance between the first and second walls, or sides, of the trough), and a length. Troughs in accordance with embodiments of the invention can have any of a variety of cross-sectional shapes, including, for example, a U-shape, a V-shape, or a rectangular (e.g., square, or rectangular) shape.

[00088] Troughs in accordance with embodiments of the invention preferably have a height that ranges from about 0.01 mm to about 5 cm, such as about 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, or 0.09 mm, such as about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, or 0.9 mm, such as about 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, or 1.9 mm, such as about 2, 3, 4, 5, 6, 7, 8, or 9 mm, or such as about 1, 2, 3, or 4 cm. Troughs in accordance with embodiments of the invention preferably have a width that ranges from about 0.01 mm to about 5 cm, such as about 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, or 0.09 mm, such as about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, or 0.9 mm, such as about 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, or 1.9 mm, such as about 2, 3, 4, 5, 6, 7, 8, or 9 mm, or such as about 1, 2, 3, or 4 cm. Any suitable combination of trough height and width can be utilized. For example, in some embodiments, a trough has a height that is greater than its width, e.g., a trough that is deeper than it is wide. In some embodiments, a trough has a width that is greater than its height, e.g., a trough that is wider than it is deep. In some embodiments, a trough has a height and a width that are approximately equal, e.g., a trough that is as wide as it is deep.

[00089] Troughs in accordance with embodiments of the invention can also optionally include one or more elements configured to retain a separating component within a trough, as well as, optionally, one or more guide components configured to guide the path of a separating component along the length of the trough. In some embodiments, for example, a trough comprises one or two edges whose thickness is increased as compared to the thermoplastic material that makes up the floor, or bottom, of the trough. In some embodiments, a trough comprises one or two edges whose thickness is greater than the thickness of the thermoplastic material that makes up the floor, or bottom, of the trough by an amount that ranges from about 5% to about 500%, such as about f 0%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, f 00%, f 25%, f 50%, f 75%, 200%, 225%, 250%, 275%, 300%, 325%, 350%, 375%, 400%, 425%, 450%, or about 475%. in certain embodiments, a thickened trough edge, as described herein, can function as a retention component, as a guide component, or as both a retention component and as a guide component.

[00090] In some embodiments, a trough comprises one or two overhanging ledges that extend from an edge of the trough and project out over the center of the trough. In some embodiments, a trough ledge has a projection length that ranges from about 5% to about 40% of the width of the trough, such as about 10%, 15%, 20%, 25%, 30%, or about 35%. In some embodiments, a trough ledge has a thickness that ranges from about 0.01 mm to about 5 cm, such as about 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, or 0.09 mm, such as about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, or 0.9 mm, such as about 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, or 1.9 mm, such as about 2, 3, 4, 5, 6, 7, 8, or 9 mm, or such as about 1, 2, 3, or 4 cm. In some embodiments, a trough ledge runs an entire length of a trough, whereas in some embodiments, a trough ledge is only disposed along certain sections of a trough. In certain embodiments, a trough ledge, as described herein, can function as a retention component, as a guide component, or as both a retention component and as a guide component.

[00091] In some embodiments, a trough comprises one or more grooves, or a combination of grooves, that are disposed on one or both of the trough walls, and/or on the floor of the trough. In some embodiments, a groove has a depth that ranges from about 0.01 mm to about 1 cm, such as about 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, or 0.09 mm, such as about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, or 0.9 mm, such as about 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, or 1.9 mm, such as about 2, 3, 4, 5, 6, 7, 8, or 9 mm. Grooves in accordance with embodiments of the invention can have any suitable cross sectional geometry, including, without limitation, U-shaped, V-shaped, rectangular (e.g., square), or irregular cross sectional geometries. In some embodiments, a groove, or combination of grooves, runs an entire length of a trough, whereas in certain embodiments, a groove, or combination of grooves, is only disposed along certain sections of a trough. In some embodiments, a groove, or a combination of grooves, as described herein, can function as a retention component, as a guide component, or as both a retention component and as a guide component.

[00092] Aspects of the invention include angular wall components that are disposed at various locations within the subject thermoplastic containers. As described above, angular wall components in accordance with embodiments of the invention preferably comprise two substantially planar features that are contiguous, and that are oriented at an angle to one another. In some embodiments, the two substantially planar features of an angular wall component form an angle that ranges from about 180° to about 10°, such as about 175°, 170°, 165°, 160°, 155°, 150°, 145°, 140°, 135°, 130°, 125°, 120°, 115°, 110°, 105°, 100°, 95°, 90°, 85°, 80°, 75°, 70°, 65°, 60°, 55°, 50°, 45°, 40°, 35°, 30°, 25°, 20°, or about 15°. In some embodiments, an angular wall component is disposed within a wall segment. In some embodiments, an angular wall component is disposed at the junction of two adjacent wall segments. In certain embodiments, an angular wall component is disposed within a base. In certain embodiments, an angular wall component is disposed within a lid.

[00093] In some embodiments, an angular wall component comprises a guide component that is configured to guide the integrated separating component to separate the thermoplastic container along the length of the angular wall component, e.g., along the ridge that is formed at the point where the two substantially planar features meet and form an angle. Such guide components can comprise, for example, a thickened region of a wall segment on either side of the ridge that guides the motion of the integrated separating component along the ridge of the angular wall component. In some embodiments, a guide component comprises a raised projection that extends from a wall segment in a direction that is perpendicular to at least one of the substantially planar features of the angular wall component, and that guides the motion of the integrated separating component along the ridge of the angular wall component. In certain embodiments, a raised projection extends outwardly by a distance that ranges from about 0.1 mm to about 5 mm, such as about 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0. 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7,

1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4.0,

4.1. 4.2.4.3.4.4. 4.5. 4.6.4.7. 4.8, or about 4.9 mm. Guide components in accordance with embodiments of the invention can comprise any suitable geometry, such as square, rectangular, rounded, etc.

[00094] In some embodiments, an angular wall component comprises a thermoplastic material that is different from the thermoplastic material of one or more other parts the thermoplastic container, e.g., the base, wall segments, and/or the lid. In some embodiments, an angular wall component comprises a thermoplastic material that is the same as the thermoplastic material of one or more other parts the thermoplastic container, e.g., the base, wall segments, and/or the lid. In some embodiments, an angular wall component comprises a thermoplastic material that comprises one or more different mechanical properties from the thermoplastic material of one or more other parts the thermoplastic container, e.g., the base, wall segments, and/or the lid.

[00095] Aspects of the invention include rupture seams that are disposed at various locations within the subject thermoplastic containers. Rupture seams in accordance with embodiments of the invention are configured to rupture, or separate, in an irreversible manner when a particular force is applied to them. In some embodiments, an integrated separating component is configured to apply a suitable force that can rupture that rupture seam.

[00096] In some embodiments, a rupture seam comprises optical (e.g., color) properties that indicate its position to a user. For example, in some embodiments, a rupture seam comprises a material that is a different color than the material of the container. In some embodiments, a rupture seam comprises a translucent or transparent material that allows a user to visualize the contents of the container and/or the fill level of the container. [00097] In some embodiments, a rupture seam can comprise a material having one or more mechanical properties that facilitate separation of the container. For example, in some embodiments, a rupture seam can comprise a geometry (e.g., a reduced thickness) that facilitates separation of the container. In some embodiments, a rupture seam is made from the same material that the remainder of the container is made from, but due to the geometry of the rupture seam (e.g., reduced thickness), the container is configured to separate along the rupture seam when a suitable force is applied. In some embodiments, a rupture seam comprises a material that is different from the material that makes up the rest of the container. In some embodiments, the material of the rupture seam has different mechanical properties than the material that makes up the rest of the container, and the different mechanical properties of the rupture seam material facilitate separation of the container along the rupture seam. In some embodiments, the joining of the rupture seam material to the rest of the container (i.e., the process of creating the container and rupture seam, from either the same material, or from two or more different materials) facilitates separation of the container. For example, in some embodiments, a container is produced using a two-shot, co-injection molding procedure, where a first material is injected into a mold to form the majority of the container, and a second material is injected into the mold to form the rupture seam(s). The junction between the rupture seam material and the container material is configured to separate when a suitable force is applied.

[00098] In certain embodiments, a rupture seam comprises a relatively long, narrow indentation that is configured to separate along the length of the indentation when appropriate force is applied.

[00099] Rupture seams in accordance with embodiments of the invention can have any suitable permeability (e.g., permeable or impermeable to air, permeable or impermeable to liquid), geometry (e.g., symmetric or asymmetric), material properties (e.g., optical properties), mechanical properties, rupture strength, or any combination thereof.

[000100] In some embodiments, a rupture seam comprises a relatively long, narrow indentation, and two sides that come together to form the rupture seam. In certain embodiments, a rupture seam comprises a symmetric geometry, wherein both sides of the rupture seam are identical on either side of the axis of the rupture seam. In certain embodiments, a rupture seam comprises an asymmetric geometry, wherein the sides of the rupture seam are not identical on either side of the axis of the rupture seam.

[000101] In some embodiments, a rupture seam is configured to generate a blunt edge after it has been separated. For example, in some embodiments, a rupture seam comprises an asymmetric geometry, similar to a zipper, wherein a plurality of teeth are positioned on either side of the rupture seam. In use, the integrated separating component passes along the rupture seam and separates the teeth, thereby opening the rupture seam and generating a blunt edge on each side of the rupture seam. This blunt edge can help prevent a user from cutting him or herself on the separated thermoplastic container by reducing the number of, or eliminating altogether, any sharp edges resulting from the separation process. [000102] Rupture seams in accordance with embodiments of the invention can have any suitable permeability. For example, in some embodiments, a rupture seam is impermeable to liquid. In some embodiments, a rupture seam is impermeable to air. In some embodiments, a rupture seam is permeable to liquid. In some embodiments, a rupture seam is permeable to air. One of ordinary skill in the art can readily select an appropriate permeability for a rupture seam based on the particular application of the thermoplastic container. For example, if a thermoplastic container is to be used to store a liquid, then the rupture seam chosen can be impermeable to liquid and air. If a thermoplastic container is to be used to store a solid material that requires ventilation, then the rupture seam chosen can be permeable to air to allow the appropriate level of breathability for the thermoplastic container.

[000103] Aspects of the invention include a rupture seam underlay that comprises a flap of material that is disposed along one or both sides of a rupture seam, and that substantially covers at least a portion the rupture seam. Rupture seam underlays in accordance with embodiments of the invention play a protective role in that they can protect a rupture seam from, e.g., becoming caked with debris, rupturing at an undesirable time or under undesirable conditions. Rupture seam underlays also play a role in modulating the permeability of a rupture seam in a desirable manner. For example, in some embodiments, a rupture seam can be permeable to air, and a rupture seam underlay can be impermeable to air. When the user wants the contents of the thermoplastic container to be ventilated, he or she can retract the rupture seam underlay, thereby exposing the rupture seam to the environment, and allowing the contents of the thermoplastic container to be ventilated.

[000104] Rupture seam underlays in accordance with embodiments of the invention can be made from any suitable material, can have any suitable permeability, and can have any suitable geometry. For example, in some embodiments, a rupture seam underlay comprises a material that is the same as the material of the thermoplastic container. In some embodiments, a rupture seam underlay comprises a material that is different from the material of the thermoplastic container. In some embodiments, a rupture seam underlay comprises a thermoplastic material that comprises one or more different mechanical properties from the thermoplastic material of one or more other parts the thermoplastic container.

[000105] In some embodiments, a rupture seam underlay is impermeable to liquid. In some embodiments, a rupture seam underlay is impermeable to air. In some embodiments, a rupture seam underlay is permeable to liquid. In some embodiments, a rupture seam underlay is permeable to air. One of ordinary skill in the art can readily select an appropriate permeability for a rupture seam underlay based on the particular application of the thermoplastic container. For example, if a thermoplastic container is to be used to store a liquid, then the rupture seam underlay chosen can be impermeable to liquid and air. If a thermoplastic container is to be used to store a solid material that requires ventilation, then the rupture seam underlay chosen can be permeable to air to allow the appropriate level of breathability for the thermoplastic container.

[000106] Rupture seam underlays in accordance with embodiments of the invention are preferably disposed on one or both sides of a rupture seam, and can be positioned on one or both sides (e.g., on an external side and/or on an internal side) of a thermoplastic container. Rupture seam underlays preferably comprises a base, or contact point, where they are connected to the thermoplastic container, and an extension component that extends away from the base to cover the rupture seam. In certain embodiments, an extension component of a rupture seam underlay is longer than the width of a rupture seam, so that the extension component of the rupture seam underlay covers the entire rupture seam, plus some additional portion of the thermoplastic container on the opposite side of the rupture seam from the base of the rupture seam underlay. In some embodiments, a rupture seam underlay is shorter than the width of the rupture seam, and only covers a portion of the rupture seam. In certain embodiments, two rupture seam underlays can be positioned on either side of a rupture seam, and the rupture seam underlays are configured to overlap with one another to cover the entire rupture seam.

[000107] In some embodiments, an extension portion of a rupture seam underlay has a length that ranges from about 1 mm to about 10 mm, such as about 2, 3, 4, 5, 6, 7, 8 or 9 mm. In some embodiments, a rupture seam underlay has a thickness that ranges from about 0.01 mm to about 5 cm, such as about 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, or 0.09 mm, such as about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, or 0.9 mm, such as about 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, or 1.9 mm, such as about 2, 3, 4, 5, 6, 7, 8, or 9 mm, such as about 1, 2, 3, or 4 cm.

[000108] As noted above, rupture seam underlays in accordance with embodiments of the invention can be retractable. In some embodiments, a rupture seam underlay can be retracted by a user at will. For example, when desired, a user can retract the rupture seam underlay, and can also move the rupture seam underlay back into position covering the rupture seam. In certain embodiments, a rupture seam underlay is configured to retract from the rupture seam when the rupture seam underlay comes into contact with the integrated separating component. For example, in some embodiments, the integrated separating component is configured to retract the rupture seam underlay(s) from the rupture seam when the integrated separating component is passed along the rupture seam.

[000109] Aspects of the invention include direction-changing components that are configured to change the direction in which a separation component is traveling. In some embodiments, a direction-changing component is configured to change a travel direction of a separating component in an orthogonal manner, wherein the separating component, upon passing through the direction-changing component, moves from a first plain to a second plain. In some embodiments, a direction-changing component is configured to change a travel direction of a separating component in an orthogonal manner, wherein the separating component, upon passing through the direction-changing component, moves from a first heading to a second, orthogonal heading, while staying within the same plain. In some embodiments, a direction-changing component is configured to change a travel direction of a separating component in a non-orthogonal manner.

[000110] Direction-changing components in accordance with embodiments of the invention can comprise any combination of troughs, grooves, angular wall components, rupture seams, retention components, and/or guide components, as described herein, wherein these elements are configured to facilitate a suitable change in the travel direction of the separation component. Direction-changing components in accordance with embodiments of the invention are generally disposed at a junction (e.g., a junction location) between two or more elements, e.g., at a junction between a base trough and a wall trough, at a junction between a wall trough and a lid trough, at a junction between a first angular wall component and a lid trough, etc. Direction-changing components can also be located, e.g., at an intersection of two base troughs, two wall troughs, two lid troughs, two angular wall components, two rupture seams, or any combination thereof. In certain embodiments, a junction location can be a comer where two or more elements meet (e.g., a wall segment and a base segment). In some embodiments, a direction-changing component can be disposed within a single element (e.g., within a single wall segment), such that the travel heading (i.e., the direction of travel) of the integrated separating component changes when the integrated separating component passes through the direction-changing component.

Separating Components

[000111] Aspects of the invention include separating components that are configured to separate two adjacent portions of a thermoplastic container, thereby allowing the container to adopt a substantially flat configuration. In some embodiments, a separating component is integrated into a thermoplastic container, whereas in some embodiments, a separating component is a separate element that is configured to work in an interoperable manner with a thermoplastic container. In certain embodiments, a separating component is configured to fit within a recessed area, or depression, on a thermoplastic container so as to be out of the way of the user of the container when the separating component is not in use. In some embodiments, a separating component is disposed within a recessed depression on the base of the container when not in use. In some embodiments, a separating component is disposed within a recessed depression in a wall segment of the container. In some embodiments, a separating component is disposed in a recessed depression in a lid of the container. In certain embodiments, a separating component is configured to separate two adjacent portions of a thermoplastic container by passing along one or more troughs, thereby separating the container in a defined, or prescribed manner, and causing the container to preferably adopt a substantially flat configuration. [000112] In some embodiments, a separating component comprises a blade. Blades in accordance with embodiments of the invention can comprise any suitable material, such as plastic, metal, glass, or any combination thereof. In one preferred embodiment, a blade is made of recyclable plastic. In some embodiments, a blade is retractable, such that it can be extended from the separating component when in use, or retracted into a protected position within the separating component when not in use. In some embodiments, a separating component comprises a blade guard that is configured to allow the blade to contact the material of the container in order to affect a separation therein, while simultaneously preventing a user from inadvertently coming into contact with the blade.

[000113] In some embodiments, a separating component comprises a blade-engaging component that is configured to cause the blade to enter into a trough and puncture the material of the thermoplastic container within the trough to start the process of separating the thermoplastic container along the length of the trough. In certain embodiments, a blade-engaging component is configured to automatically engage the blade with a trough when the separating component is removed from the recessed depression.

[000114] In some embodiments, a separating component comprises a C-shaped component comprising a recessed area in the center of the C shape, wherein the blade is located within the recessed area. Positioning the blade in the recessed area helps to protect the user from coming into contact with the blade. In certain embodiments, the recessed area of the C-shaped component is configured to engage with one or more portions of the thermoplastic container. For example, in some embodiments, the C- shaped component is configured to engage with both an external side and an internal side of the thermoplastic container by having a geometry that is complementary to the geometry of the thermoplastic container.

[000115] In some embodiments, a separating component comprises a tear-initiating component that is configured to initiate a tear in the material of the thermoplastic container within a trough. In some embodiments, the separating component is configured to propagate the tear along the length of a trough. Tear-initiating components, in some embodiments, can be blade-like in nature, but are not required to contain a sharpened edge.

[000116] In some embodiments, a separating component comprises a pull tab that is configured to allow a user to grasp the separating component and to apply a force to the separating component. The force applied to the separating component is sufficient to either cause a blade in the separating component to cut the material of the thermoplastic container along the length of a trough, or to affect the initiation and propagation of a tear in the material of the thermoplastic container along the length of a trough. In certain embodiments, the pull tab comprises a ring having a suitable size for a user to engage one or more fingers with the ring to exert the desired amount of force.

[000117] In some embodiments, a separating component comprises a geometry that conforms to a cross- sectional geometry of a trough. For example, in some embodiments, a trough can have a U-shaped cross-sectional geometry, and the separating component can also have a U-shaped cross-sectional geometry so that the separating component is retained with the trough. In certain embodiments, as described herein, a trough can comprise, e.g., one or more retention components, such as one or more ledges extending from an edge of the trough, which serve to retain the separating component within the trough, and/or guide the separating component to travel in the direction of the length of the trough. Depending on the cross-sectional geometry of the troughs used in a particular thermoplastic container, a suitable and complimentary cross-sectional geometry can be selected for the separating component in order to ensure compatibility. In some embodiments, a separating component comprises a spherical shape that is configured to conform to a rounded, or U-shaped geometry of a trough. In such embodiments, the spherical separating component can travel in a non-linear direction along a trough, since its geometry does not constrain it to rectilinear movements. In certain embodiments, a trough has a non-linear trajectory, for example, containing one or more arcs, curves, corners, and/or other non linear features, and a separating component, such as a spherically-shaped separating component, can traverse the trajectory of the trough along such features in a continuous manner.

[000118] In some embodiments, a separating component comprises one or more elements that conform to a cross-sectional geometry of a groove, or a combination of grooves. In certain embodiments, as described herein, a groove, or a combination of grooves, can serve as a retention component and/or as a guide component, which functions to retain the separating component within the trough, and/or guide the separating component to travel in the direction of the length of the trough. Depending on the cross- sectional geometry of a groove, or a combination of grooves, used in a particular trough, a suitable and complimentary cross-sectional geometry can be selected for the separating component in order to ensure compatibility.

[000119] In certain embodiments, an integrated separating component comprises a wedging component that comprises a blunt end and one or more inclined surfaces. In use, the wedging component is configured to convert a force applied to the blunt end into forces that are perpendicular to the one or more inclined surfaces. These forces can be applied to the teeth of a rupture seam, thereby separating the teeth and opening the rupture seam in the same way that a zipper fastener separates the teeth of a zipper.

[000120] Aspects of the invention further include one or a plurality of integrated separating components configured to irreversibly separate the container into one or more component parts of a predetermined configuration. In addition, it should be noted that the integrated separating component(s) are such that that they do not adversely influence the container’s ability to contain a given liquid or solid medium. Accordingly, the shelf life of the container herein is not otherwise adversely influenced by the presence of the integrated separating component(s) which now provide a user the convenience of reconfiguring the container into a geometric form that is relatively more amenable to plastic recycling operations along with improved shipping/storing capability.

Materials

[000121] The subject thermoplastic containers and components thereof (e.g., caps), can be constructed from any suitable thermoplastic material, preferably from a recyclable thermoplastic material. Recyclable thermoplastic materials are generally known in the art, and include, without limitation, petroleum-based plastics and bioplastics. Non-limiting examples of petroleum-based plastics include: polyethylene terephthalate (PET), high-density polyethylene (HDPE), polyvinyl chloride (PVC), low- density polyethylene (LDPE), linear low density polyethylene (LLDPE), medium density polyethylene (MDPE), metallocene based polyethylene (mPE), polypropylene (PP), polystyrene (PS), acrylic, polycarbonate, copolymers of any such resins, or any combination thereof, or any equivalents thereof. Non-limiting examples of bioplastics include: starch-based plastics, cellulose-based plastics, protein- based plastics, lipid-based plastics, or any combination thereof. Any suitable thermoplastic material or combination of suitable thermoplastic materials, or any equivalents thereof, can be used to construct the subject thermoplastic containers.

[000122] In some embodiments, a thermoplastic container as described herein, including all components thereof, is made entirely of the same material. In some embodiments, a thermoplastic container comprises two or more different materials. For example, in one embodiment, a thermoplastic container is made from a first material, and the cap is made from a second, different material; in one embodiment, a wall segment is made from a first material, and a wall bough is made from a second, different material. In certain embodiments, two or more different portions of a thermoplastic container can contain the same material, but the material can have different mechanical properties in each different portion of the container. For example, in some embodiments, the base, wall segment and lid of a container comprise a first material having a first mechanical property, e.g., a first fracture toughness value, and the boughs of the thermoplastic container also comprise the first material, but have a second, different mechanical property, e.g., a second fracture toughness value.

[000123] In some embodiments, a separating component is made from a material that is different from the material that constitutes the remainder of the thermoplastic container. For example, in one embodiment, a thermoplastic container is made of a first material, and a separating component is made of a second, different material. In certain embodiments, both the first material and the second material are recyclable.

[000124] In certain embodiments, one or more components of the subject thermoplastic containers comprise a degradable material, a biodegradable material, a compostable material, or any combination thereof. Non-limiting examples of such materials include: polyhydroxy alkanoate (PHA); polylactic acid (PLA); cellulose acetate (CA); starch (e.g., corn, potato, tapioca, etc.); cellulose; soy protein; polybutylene succinate (PBS); polycaprolactone (PCL); polybutyrate adipate terephthalate (PBAT); and polyvinyl alcohol (PVA).

Methods of Manufacture

[000125] Thermoplastic containers in accordance with embodiments of the invention can be manufactured using any of a variety of suitable manufacturing techniques, including, but not limited to, thermoforming, blow molding, injection molding, compression molding or additive manufacturing.

[000126] Thermoforming broadly covers a number of processes such as vacuum forming, billow forming, plug assist vacuum forming and pressure forming. Matched die molding is similar in many ways, and is sometimes referred to as thermoforming if it involves the process of heating a sheet of material. Blow molding is also a broad process term, and includes extrusion blow molding, injection-stretch blow molding, stretch blow molding, or accumulator blow molding. Additive manufacturing, also referred to as 3D printing, is a rapidly evolving process that uses computer-aided-design (CAD) software or 3D object scanners to direct hardware to deposit material, layer upon layer, in precise geometric shapes. As its name implies, additive manufacturing adds material to create an object. By contrast, when an object is created by traditional means, it is often necessary to remove material through milling, machining, carving, shaping or other means. Injection molding and co-injection molding processes involve the injection of molten material(s) into a mold, where they solidi y to produce an object. All of the processes listed above can be adapted for use with a single material, or can be adapted to utilize multiple materials.

[000127] For example, thermoforming processes can be utilized multi-layer fdms or sheets, or monolayer sheets, depending on the particular application. Injection molding processes can also use multiple materials. For example, co-injection molding processes can be used to produce multi-layer products over most of the product surface area. Multi-shot injection molding processes (e.g., 2 shot molding) use two materials which are“adjacent” to one another at selected locations. The use of the second material allows for the control of tear forces based on both the cohesive (internal) strength of the second material and the adhesive strength between the two different materials, either or both of which properties can be tuned to achieve one or more desired characteristics of a container produced therefrom.

[000128] Blow molding processes can also be used to produce objects comprising single or multiple materials. For example, extrusion blow molding can utilize a single material or multi-materials. A co extrusion blow molded container could be“multi-layer”, having an inner layer over most or all of the surface area of the container. In some embodiments, a second material could be deposited in the form of stripes. In some embodiments, such stripes can have different material properties, such as, e.g., different optical properties (for example in the case of an oil bottle containing transparent stripes that allow visualization of the liquid level in the container), or different mechanical properties (for example, the ability to tear more easily than the material that makes up the majority of the container).

[000129] Additive manufacturing processes can also be single material or multi-material processes. For example, aspects of the invention relate to thermoplastic containers wherein the integrated separating component is produced by integrating a separating component into a homogenous single material for the container, or by producing the separating component from a second material.

Systems

[000130] Aspects of the invention include systems comprising various components of the subject thermoplastic containers. In some embodiments, a system comprises a thermoplastic container comprising a base comprising a plurality of edges along its perimeter, a plurality of wall segments extending orthogonally from each edge of the base, and a separating component configured to separate the thermoplastic container, thereby allowing the thermoplastic container to adopt a substantially flat configuration. In some embodiments, a thermoplastic container further comprises at least one bough, angular wall component, or rupture seam, disposed within a wall segment of the thermoplastic container, and at least one bough, angular wall component, or rupture seam disposed between a first edge of the base and a wall segment, and the separating component is configured to separate the thermoplastic container along troughs, angular wall components, or rupture seams, thereby allowing the thermoplastic container to adopt a substantially flat configuration.

[000131] As reviewed herein, in some embodiments, a separating element is integrated into the thermoplastic container. In some embodiments of the subject systems, a separating component is a separate element, and is configured to be inboduced into the material of the thermoplastic container, and to separate the material of the thermoplastic container, e.g., along at least one bough, angular wall component, or rupture seam. In some embodiments, a separating component is disposed within a stand alone apparatus, and the apparatus is configured to receive a thermoplastic container within a receptacle. Once the thermoplastic container has been placed within the receptacle, the apparatus can be operated to separate the thermoplastic container, e.g., along one or more boughs, angular wall components, or rupture seams, thereby causing the thermoplastic container to adopt a substantially flat configuration.

Methods

[000132] Aspects of the invention include methods for converting (e.g., unfolding) a thermoplastic container from a three dimensional configuration to a substantially flat configuration. In some embodiments, the methods involve engaging a separating component, as described herein, with the material of a thermoplastic container, as described herein, so that the separating component initiates a separation in the material of the thermoplastic container. In some embodiments, the separation in the material is located within a trough, along an angular wall component, or along a rupture seam, or any combination thereof, as described herein. In some embodiments, the methods further involve applying a force to a pull tab on the separating component, thereby causing the separating component to move along the length of a trough, an angular wall component, or a rupture seam, or any combination thereof, and to separate the material of the thermoplastic container along the length of the trough, the angular wall component, or the rupture seam, or any combination thereof. In certain embodiments, the methods involve passing the separating component through one or more direction-changing components to transition the separating component from a first trough, angular wall component, or rupture seam to a second trough, angular wall component, or rupture seam.

[000133] In some embodiments, the methods involve completely separating a portion of the thermoplastic container from a remainder of the thermoplastic container. For example, in some embodiments, the methods involve passing the separating component along an entire perimeter of a lid or a base, thereby separating the lid or the base from the remainder of the material that constitutes the container. In some embodiments, this method provides a separation of different materials that are used to make the majority of the thermoplastic container (e.g., the wall segments) from specific material(s) that are used to make, e.g., the cap. By separating the cap and a portion of the lid from the remainder of the thermoplastic container, the user is able to recycle these two separate components in different ways. For example, if the material that makes up the base and wall segments is a compostable material, and the material that makes up the cap is not compostable, then the base and wall segments can be placed in a compost bin, while the cap can be placed in a standard (non-compostable) plastic recycling bin.

[000134] In some embodiments, the methods involve only partially separating a portion of the thermoplastic container from the remainder of the container, thereby allowing the container to adopt a substantially flat configuration, while still maintaining an attachment between some components of the container. For example, in some embodiments, the methods involve passing a separating component along three edges of a square-shaped base, thereby separating three sides of the base from their adjacent wall segments, but leaving one edge of the base connected to its adjacent wall segment, resulting in a container with a substantially flat configuration, with the base attached to the wall segments along only one edge of the base, forming a hinge-like connection between the base and the attached wall segment.

[000135] Turning now to the figures, FIG. 1 depicts of variety of different bases that can be utilized in the subject thermoplastic containers. Panel A shows a triangular base having three edges. Panel B shows a square base having four edges. Panel C shows a pentagonal base having 5 edges. Panel D shows a hexagonal base having six edges. Panel E demonstrates that as the number of edges on a base increases, the shape of the base approaches a circle. Also illustrated in FIG. 1 are three-dimensional representations of a container comprising the above-described base geometries. Notably, as the number of sides of the container increases, the geometry approaches a round, or circular shape. In some embodiments, a container comprises a round or oval base, and a cylindrical or ovoid three-dimensional shape when formed into a container in accordance with embodiments of the invention.

In the depicted embodiment, a rupture seam or trough is present, passing along an angular wall component from the top of the container to the base. At the junction of the base and the lower wall segments, the rupture seam or trough turns 90 degrees and then traverses five edges of the base. In use, the container depicted in FIG. 4, panel F is separated along the depicted rupture seam or trough, and the container is then transitioned from a three-dimensional configuration to a substantially flat configuration. Panel G shows the container depicted in panel F after it had been transitioned into a substantially flat configuration by separating the container along the rupture seam or trough using an integrated separating component.

[000140] FIG. 4, panel H shows a six-sided container in accordance with one embodiment of the invention. In the depicted embodiment, a rupture seam or trough is present, passing along the entire circumference of the container’s longitudinal axis. In some embodiments, the depicted rupture seam is created using a co-extrusion blow molding process.

In use, the depicted container is separated along the rupture seam or trough, causing the two sides of the container to splay outward, as depicted in panel K. The rupture seam or trough in the base of the depicted embodiment is configured to form a hinge, allowing the two parts of the container to splay outward, folding along the hinge, after the container has been separated along the rupture seams or troughs. In some embodiments, as depicted in panel L, the splayed open containers are stackable.

[000142] FIG. 4, panel M, shows a container in accordance with one embodiment of the invention. In the depicted embodiment, two rupture seams or troughs are present, each traversing the container from the top to the base along the wall segments, and each positioned on opposite sides of the container. In some embodiments, the depicted rupture seam is created using a co-extrusion blow molding process. Also depicted are two pull tabs positioned on opposite sides of the container, and oriented to provide a user with leverage to separate the container along the rupture seam or trough. In use, the depicted container is separated along the rupture seams or troughs, causing the two sides of the container to splay outward, as depicted in panel N. In the depicted embodiment, the base of the container is flexible enough that the two sides of the container can splay outward even when no groove or indentation is present in the base. In some embodiments, as depicted in panel O, the splayed open containers are stackable.

[000143] In some embodiments, a rupture seam or trough as depicted in FIG. 4 is created using a co extrusion blow molding process. In use, the depicted container is separated along the rupture seam or trough to create two separate pieces, or two pieces that are hingedly connected to each other. In certain embodiments, a container comprises at last two pull tabs that are positioned on opposite sides of the container from one another, and are configured to allow a user to pull on the pull tabs to assist with separating the container along the rupture seam or trough.

[000144] FIG. 5 depicts a thermoplastic container in a three-dimensional configuration, and in various stages in the process of transitioning from a three-dimensional configuration to an unfolded, two- dimensional configuration. In Panel A, the thermoplastic container 500 is depicted in a three- dimensional configuration. The thermoplastic container 500 comprises a base 301, four wall segments 302, a lid 400, three base troughs 305, one wall trough 306, and three lid troughs 401. In Panel B, the thermoplastic container has been separated along two wall troughs, and along one lid trough, resulting in the thermoplastic container having one open end. In Panel C, the thermoplastic container has been separated along three wall troughs, and along two lid troughs, resulting in the thermoplastic container having one open end and one open side, with the lid segment attached to an adjacent wall segment. In Panel D, the thermoplastic container has been separated along four wall troughs, and three lid troughs, resulting in the thermoplastic container adopting a substantially flat configuration.

[000145] FIG. 6 depicts a variety of troughs, guide components, and retention components that can be utilized in the subject thermoplastic containers. Panel A is a cross-sectional view of a trough having a rectangular shape, as well as a perspective view. Panel B is a cross-sectional view of a bough having a U-shape, as well as a perspective view. Panel C is a cross-sectional view of a bough having a V-shape, as well as a perspective view. Panel D is a cross-sectional view of a trough having a rectangular shape, and having two projecting ledges that extend from the edges of the bough, as well as a perspective view. The depicted projecting ledges can serve as guide components, as retention components, or as both guide components and retention components. Panel E is a cross-sectional view of a bough having a U- shape, as well as a perspective view, and comprising a thickened bough edge that can serve as a guide component, as a retention component, or as both a guide component and a retention component. Panel F is a cross-sectional view of a trough having a V-shape, as well as a perspective view. The depicted bough also comprises two V-shaped grooves disposed in the walls of the bough. The depicted grooves can serve as a guide component, as a retention component, or as both a guide component and a retenbon component.

[000146] FIG. 7, panel A depicts a top view of a direction-changing component that can be utilized in the subject thermoplastic containers. In the depicted embodiment, the direction-changing component 700 comprises a first entry point 701, an exit point 702, and a second entry point 703. In use, a separating component enters the direction changing component 700 on a first pass at the first entry point 701, and changes direction by 90 degrees as it baverses to the exit point 702. On a second pass, the separating component enters the direction-changing component at the second entry point 703, then exits the direction-changing component at the exit point 702. Panel B depicts a container in accordance with one embodiment of the invention, showing the location of the direction-changing component depicted in panel A in the larger context of the entire container. In this depicted embodiment, separating the container along the depicted rupture seam or bough completely separates the lid from the remainder of the container, thereby creating two different component parts.

Utility

[000168] The subject thermoplastic containers, systems and methods are useful in a variety of ways, including, but not limited to, providing enhanced recyclability. For example, by adopting a substantially flat configuration, the subject thermoplastic containers have a reduced, or eliminated, internal void volume. By converting to a substantially flat configuration, the subject thermoplastic containers take up less space in recycling centers, and can also be transported more efficiently. Furthermore, by adopting a substantially flat configuration, the subject thermoplastic containers help to eliminate standing water, which can present public health risks. For example, standing water is known to facilitate breeding of insects, such as mosquitos, which can transmit diseases, such as malaria. Furthermore, the enhanced recyclability of the subject thermoplastic containers further reduces the environmental impact of disposable containers by reducing wildlife consumption of inedible waste.

[000169] The subject thermoplastic containers, systems and methods also provide enhanced recyclability by facilitating easier cleaning of the interior surface of the containers. By adopting an alternate configuration, such as a substantially flat configuration, more internal surfaces of the subject containers become easily accessible, and can be effectively cleaned prior to recycling. This is in contrast to existing thermoplastic containers, where the inner surface can only be accessed via the opening of the container, which constrains cleaning processes.

[000170] Additionally, the subject thermoplastic containers, systems and methods facilitate a reduction in the carbon dioxide emissions attributable to recycling activities. Through improvements in transportation efficiency, more cost-effective waste management procedures, and more efficient after- market use of recyclable materials, the carbon footprint associated with production, use and recycling of the subject thermoplastic containers is reduced as compared to the carbon footprint associated with the same activities as applied to existing thermoplastic containers.

[000171] The invention now being fully described, it will be apparent to one of ordinary skill in the art that various changes and modifications can be made without departing from the spirit or scope of the invention.

EXAMPLES

Example 1: Thermoplastic Container

[000172] A thermoplastic container having a three-dimensional configuration is formed from a square base with four sides, four wall segments, each having a rectangular shape, and a square lid comprising a proximal end and a distal end, wherein the proximal end comprises four edges, and the distal end comprises a cap. The base comprises three base troughs, each disposed between one edge of a base and an adjoining wall segment. One of the wall segments comprises a wall trough positioned within the wall segment. The lid comprises four lid troughs, each disposed between one edge of the lid and an adjoining wall segment. A first direction-changing component is disposed at a junction of a base trough and the wall trough. A second direction-changing component is disposed at a junction of the wall trough and a lid trough. Disposed within the base is a recessed depression that houses a separating component.

Example 2: Method of converting a thermoplastic container

[000173] The thermoplastic container of Example 1 is converted from a three-dimensional configuration into a substantially flat configuration. The separating component disposed in the recessed depression in the base is removed from the depression, thereby initiating a tear in the material of the thermoplastic container within one of the base troughs. The separating component is then passed along the three base troughs to separate the base from the remainder of the container in a hinged manner, wherein the base remains connected to the remainder of the container along one edge, where it is connected to an adjoining wall segment. The separating component is passed through the first direction-changing component to transition the separating component from a base trough to the wall trough. The separating component is passed along the wall trough and into the second direction-changing component to transition the separating component from the wall trough into one of the lid troughs. The separating component is passed along all four of the lid troughs to separate the lid from the thermoplastic container. The separated lid portion, which comprises the cap, is recycled in a suitable manner. The remainder of the container, which comprises the base and the wall segments in a substantially flat configuration, is recycled in a suitable manner.

Example 3: System and method for converting thermoplastic containers

[000174] A thermoplastic container having a three-dimensional configuration is converted into a substantially flat configuration using a separating component that is disposed in a stand-alone apparatus. The thermoplastic container comprises a square base with four sides, four wall segments, each having a rectangular shape, and a square lid comprising a proximal end and a distal end, wherein the proximal end comprises four edges, and the distal end comprises a cap. The base comprises three base troughs, each disposed between one edge of a base and an adjoining wall segment. One of the wall segments comprises a wall trough positioned within the wall segment. The lid comprises four lid troughs, each disposed between one edge of the lid and an adjoining wall segment. A first direction-changing component is disposed at a junction of a base trough and the wall trough. A second direction-changing component is disposed at a junction of the wall trough and a lid trough.

[000175] An operator obtains an empty thermoplastic container as described above, and places the thermoplastic container in a receptacle of an apparatus comprising a separating component. The operator then initiates a separation procedure, which proceeds by initiating a tear in the material of the thermoplastic container within one of the base troughs. The separating component is then passed along the three base troughs to separate the base from the remainder of the container in a hinged manner, wherein the base remains connected to the remainder of the container along one edge, where it is connected to an adjoining wall segment. The separating component is then passed through the first direction-changing component to transition the separating component from a base trough to the wall trough. The separating component is then passed along the wall trough and into the second direction changing component to transition the separating component from the wall trough into one of the lid troughs. The separating component is then passed along all four of the lid troughs to separate the lid from the thermoplastic container. The separated lid portion, which comprises the cap, is recycled in a suitable manner. The remainder of the container, which comprises the base and the wall segments, is recycled in a suitable manner.

Example 4: Injection molded container

[000176] In one embodiment, an injection molded container comprises one or more tear strips as part of the integrated separating components. Separating components, such as those depicted in FIG. 16, comprise integral material strips that are bounded on each side by wall troughs having a reduced thickness, and therefore, reduced strength. Each tear strip can incorporate a pull tab to facilitate initiation of a tear. In some embodiments, the tear strips are oriented in such a way as to eliminate undercuts that would prevent distortion or damage to the container during the part ejection step of the injection molding process, thereby eliminating the need for complicated moving mold sections. In some embodiments, hinge features, such as those shown in FIG. 5, panel C, can be added at intact corners (i.e., those corners that are designed not to separate) to facilitate transitioning the container into a substantially flat configuration after tearing of the separating components. In some embodiments, the tear strips can be designed to fully separate from the collapsed container, or remain as an integral component of the collapsed container for greater recycling efficiency.

Example 5: Two-shot injection molded container

[000177] In one embodiment, an injection molded container is produced using a multi-shot injection molding process (i.e., a two shot injection molding process) as depicted in FIG. 20. In some embodiments, the container is produced in a two-step injection molding process. In the first step, the bulk of the container (i.e., all portions of the container except for the separating components and the rupture seams) are injection molded from a first thermoplastic material. The molded part associated with this first step is depicted in FIG. 20, panel B. The molded and solidified thermoplastic container is then transferred to a second mold cavity, using a rotating platen or another suitable multi-shot process part transfer apparatus, where a second shot of the same or different thermoplastic material is injected to form the separating component and rupture seam sections of the container. The fully molded container associated with this second shot is depicted in FIG. 20, panel C. Depending on the mold design, each separating component can (i) have its own material injection point or (ii) use a single injection point and an integral runner to direct material to the separating components. In some embodiments, the separating component and the forces that it exerts on the components of the container are controlled by the degree of welding and/or adhesion between the two materials, as well as the joint design features employed, such as surface area of contact. FIG. 20 depicts a half lap joint design, but other joint designs, including but not limited to butt joints, tongue and groove joints, scarf joints and V- groove joints are also possible. In some embodiments, the separating components can comprise a pull tab in order to facilitate initiation of the separating process. Selection of the thermoplastic material combination, process conditions and joint design can be optimized based on the forces that need to be generated to successfully separate the container. In some embodiments, the second thermoplastic material used to produce the separating components is the same as the material used to create the bulk of the container, in order to facilitate recycling of the collapsed container. In some embodiments, the second material is compatible with the material of the container so as to allow comingled recycling of the collapsed container. In some embodiments, the material used to make the separating component does not have the same recyclability properties as the material that makes up the bulk of the container, and as such, the separating component is configured to be separated from the remainder of the container, and separately recycled.

Example 6: Blow molded container

[000178] In one embodiment, a container comprises separating components that are produced using a thermoplastic blow molding process, such as a co-extrusion or co-injection blow molding process. Co extrusion blow molding processes are used to produce thermoplastic containers having one or more stripes of material having different color or light transmission characteristics. Examples of such containers and processes are described, for example, in US Patent No. 3,343,568, the disclosure of which is incorporated by reference herein in its entirety. The co-extruded stripe(s) extend longitudinally over the length of the extruded tube or parison that is then blown with compressed gas to form the container as shown in FIG. 4, panel H. The integral extruded stripes extend through the thickness of the container and typically serve as a sight or level indicator for the container contents. The thermoplastic material used for the stripe(s) is generally similar to that of the container itself, except that in some embodiments the material is visually different. In certain embodiments, the material used for the stripe(s) is structurally equivalent, while in other embodiments, the material used for the stripe(s) is structurally different (e.g., has different mechanical properties).

[000179] In one embodiment, the stripes are positioned and formulated to function as an integrated separating component, designed to facilitate transition of the container from a first configuration to a second configuration (e.g., a stackable configuration, or a substantially flat configuration) for enhanced recyclability. In some embodiments, the container and stripe materials are selected to provide sufficient structure for the container application, however, the adhesion between the stripe(s) and the adjacent container wall sections allows for separation when the container is broken down. In some embodiments, the container wall sections adjacent to the stripe(s) can also include pull tab-like features that facilitate separation of the container into one or more component parts of predetermined configuration. Embodiments comprising one or more of the features described above can also be produced using, e.g., a co-extrusion blow molding process, an accumulator blow molding process, and/or an injection blow molding process (using co-injection molded stripe preforms).
