Introduction

[0040] Dispensers may be provided in accordance with an embodiment of the invention. The dispensers may be capable of containing one or more sachets therein. Sachets can be small packets useful for holding various products, such as sugar packets. The dispenser may have one or more shell, inserts and/or armature (e.g., frame) that may be used to contain the sachets. In some instances, dispensers or portions of the dispensers may have one or more characteristics, features, components or utilize one or more steps described in U.S. Patent Application Serial No. 61/533,137, U.S. Patent Publication No. 2011/0036846, U.S. Patent Publication No. 2011/0220652, U.S. Patent Publication No. 2011/0290798, and U.S. Patent Application Serial No. 13/315,242, which are hereby incorporated by reference in their entirety.

[0041] A dispenser may be useful for packing sachets within. For example, a dispenser may function as a carrying container, sachet holder, purse pack, wallet, or kit of the same or mixed items. The dispenser may be shaped or fitted to be easily inserted into a purse, bag, compartment, pocket, or to be carried by hand. The dispenser may have a durable outer casing and inner features that may be capable of holding sachets. The dispenser may have a footprint (e.g., cross-sectional area) of about 500 cm 2 or less, or 400 cm 2 or less, or 400 cm 2

3 3 3

100 cm or less, or 50 cm or less, or 10 cm or less.

[0042] Sachets may include packets, or disposable bags or pouches. Sachets may contain consumer goods therein. The sachets may be single-use (e.g., contain a single dose therein), or may be used multiple times (e.g., contain multiple doses therein). In some instances, sachets may be linked one to the other, and may be separated by the user. In some instances, the sachets may or may not be reclosable or resealable for multiple uses. Sachets may include a wrapping that may cover items therein. Sachets may or may not be air-tight and/or fluid-impermeable. In some instances, a sachet may be initially sealed. Sachets may prevent objects contained therein from flowing out or dropping out. In some instances, sachets may be formed of a tearable or cuttable material. For example, a user may tear open a sachet to access the item contained therein. A sachet may or may not have a perforation, notch, or other feature that may assist with opening and/or tearing the sachet. Multiple linked sachets may or may not have a perforation, notch or other feature to facilitate their separation.

[0043] Examples of items enclosed within sachets may include but are not limited to gels, powders (e.g., powdered beverages or food), coffee, food, baby food, medicine, medical supplies, vitamins, cosmetics, towelettes, personal care items, beverages, syrups,

concentrates, vitamins, soaps, dyes, inks, or solids.

[0044] Sachets may be provided within the dispenser. In some instances, sachets may be disposable. The dispenser may or may not be disposable, or may or may not be multi-use. A user may refill the dispenser with additional sachets. A user may reposition or reorder contents of the dispenser. For example, the user may be able to adjust the positioning of sachets within the dispenser, remove sachets from the dispenser, and/or add sachets to the dispenser. Sachets may have fixed positions within the dispenser or movable positions within the dispenser. Sachets may have assigned positions within the dispenser which may or may not be altered or reordered.

[0045] The sachets herein can be secured within and supported by a dispenser case. The dispenser case can be designed such that the sachets can be secured within the dispenser case without adhesives. Alternatively, adhesives may be used to assist with securing the sachets in the dispenser case. The sachets may or may not move freely within the dispenser case.

[0046] The dispenser may advantageously provide modularity. The dispenser may be of a suitable size and/or shape for a user to carry. The dispenser may have a form factor that may retain sachets and provide easy access to the sachets when desired. The dispenser may have user friendly contacts or control areas. In some instances, the dispenser may have rounded shapes or corners that may reduce the likelihood of snagging or denting. The rounded shapes or corners may cause the dispenser case to fit comfortably within a user's hand or slip easily into a user's purse. Thermoformed pulp may in some cases serve as a suitable for making rounded shapes because of its moldability.

[0047] Portability may be provided by the dispenser design. The dispenser may be sized and/or shaped to be easily carried in a number of situations. The dispenser may have a smooth/profiled shape that may be aesthetically and/or tactilely pleasing to a carrier. In some instances, the dispenser may be shaped to provide material savings. For example, the dispenser need not have overlapping material as provided in cases of folded materials, such as boxes. In some instances, a technique for forming the dispenser may be utilized that may involve molding the dispenser to the desired shape without extraneous material folded or layered over. [0048] The dispenser may also advantageously provide compartmentalization and organization for sachets within. Sachets may be retained within one or more compartment of the dispenser. In some embodiments, one, two or more compartments may be provided. Sachets may be provided within the one, two or more compartments. In some embodiments one or more different types of sachets, or sachets holding different items may be provided. In some instances, different sachets may be provided within different compartments.

Alternatively, different sachets may be provided within the same compartment. In some instances, different sachets may be provided within different regions of the same

compartment.

[0049] Different compartments may have the same size and/or configuration or different sizes and/or configurations. In some embodiments, the compartments may have various configurations depending on the objects contained therein. For example, an elongated compartment may be provided for long sachets, while a small compartment may be provided to contain rubbish or other items.

[0050] In some embodiments, the dispenser may include a shell that may enclose one or more sachets therein. The shell may be formed of a biodegradable material, such as molded fiber or pulp or paper. Further examples of shell materials may be described elsewhere herein. The shell may advantageously be formed using pulp thermoforming, which is a matched tool process where the interior and exterior part surfaces are defined. In some embodiments, thermoforming may have advantages over other techniques such as wet molding or wet thermoforming of agri-fiber. Thermoforming may permit a desired thickness or detail to be present, and may provide greater control over thickness or ranges of thicknesses and details. This may be particularly useful for dispensers of smaller size or that have tighter tolerances. Thermoforming may also provide greater control over density of the shell material and/or level of finish on the interior and/or exterior of the dispenser shell.

[0051] The wall thickness of the dispenser case may be at least about 1 mm, or at least about 2 mm, or at least about 3 mm, or at least about 4 mm, or at least about 5 mm, or at least about 6 mm, or at least about 7 mm, or at least about 8 mm, or at least about 9 mm, or at least about 10 mm, or at least about 11 mm, or at least about 12 mm, or at least about 13 mm, or at least about 14 mm, or at least about 15 mm, or at least about 16 mm, or at least about 17 mm, or at least about 18 mm, or at least about 19 mm, or at least about 20 mm, or at least about 21 mm, or at least about 22 mm, or at least about 23 mm, or at least about 24 mm, or at least about 25 mm, or at least about 26 mm, or at least about 27 mm, or at least about 28 mm, or at least about 29 mm, or at least about 30 mm, or more. The thickness may be uniform throughout the body of the dispenser, or non-uniform. In some cases, the thickness throughout the body of the dispenser may vary by at least about 0.5%, or at least about 1.0%>, or at least about 1.5%, or at least about 2.0%, or at least about 2.5%, or at least about 3.0%, or at least about 3.5%, or at least about 4.0%, or at least about 4.5%, or at least about 5.0%, or at least about 10.0%, or at least about 15.0%, or at least about 20.0%, or at least about 25.0%, or at least about 30.0%, or at least about 35.0%, or at least about 40.0%.

[0052] The density may be uniform throughout the body of the dispenser, or non-uniform. The average density of the dispenser case from thermoformed pulp may be about 0.30g/cm ,

3 3 3 3

or about 0.40 g/cm , or about 0.50 g/cm , or about 0.60 g/cm or about 0.70g/cm , or about 0.80 g/cm , or more. The density of the dispenser at any given part of the dispenser can be 95%, or 90%, or 85%, or 80%, or 75%, or 70%, or 65%, or 60%, or 55%, or 50%, or 45%, or 40%), or 35%), or 30%>, or 25%, or 20%> of the average density of the dispenser case, or greater. The density of the dispenser at any given part of the dispenser can be 105%, or 1 10%, or 1 15%, or 120%, or 125%, or 130%, or 135%, or 140%, or 145%, or 150%, or 155%), or 160%), or 165%, or 170%), or 175%), of the average density of the dispenser case, or greater.

[0053] The dispenser may be formed of a hybrid design which may include the

combination or interplay of multiple materials. For example, two types of fiber/grain materials may be used. In one example, a dispenser may have a pulp component and a paper/cardboard component. In one example, a shell may be formed of a molded pulp or fiber material while an internal compartment holder may be formed of a paper/cardboard material. In some instances, different characteristics and/or function may be provided by the different materials. For example, physical and/or mechanical characteristics of molded pulp and folded paper may be utilized. In one example, the shell formed from molded fiber or pulp may provide a sturdy contoured outer casing, while a paper compartment holder may retain sachets therein while providing a surface for colorful printing or other purposes.

Utilizing one or more paper or cardboard features may be useful for graphics and

communication. Such components may be provided on an external surface of the dispenser, or internal surface or component of the dispenser. Components may be provided that may include molded-in information, labels, and/or that can form part of the tamper evidence strategy. In some instances, the dispenser may be formed from a single material, such as those materials described elsewhere herein, including a thermoformed material.

[0054] Dispensers provided herein may advantageously achieve a desired configuration and form. For example, the dispenser form may permit the dispenser to be carried in purse. The dispenser may be soft, smooth, and/or handleable. The dispenser may also allow for merchandizing. For example, the dispenser may stand upright, or hang on a peg board, such as at point of purchase.

Dispenser case

[0055] A dispenser may include a case. The dispenser case may accept sachets and/or integrate the sachets with a dispenser frame. The case may be formed of a single shell or a plurality of shells. The plurality of shells may or may not be connected to one another. A plurality of shells may be integral to one another, be permanently affixed to one another or removably attached to one another. Any description herein of a dispenser shell or dispenser case may also apply to a dispenser case having multiple shells.

[0056] A dispenser case may be formed of any material having a desired material property. For example, the case can comprise biodegradable materials, such as molded fiber or pulp or paper. The material used for forming the case may be but need not be food-grade. For example, the case may comprise 100% post-consumer fiber or pulp feedstock. The dispenser cases or other materials described herein can include virgin pulp fiber. The dispenser case can comprise type-2 molded fiber, type-2A thermoformed fiber, type-3 thermoformed fiber, type- 4 thermoformed fiber, molded fiber, matched tool molded fiber, X-RAY formed fiber, infrared formed fiber, microwave formed fiber, vacuum formed fiber, structural fiber, compression formed fiber, wet press fiber, wet press with hot after press formed fiber, sheet stock, recycled plastic or any other structural material. In a preferable embodiment, the case may be formed of any agri-fiber, such as pulp. The case may be formed from one of more processed forms of agri-fiber suitable for molding and/or thermoforming. In some instances, the case may be formed of a material other than cardboard or paper (e.g., corrugated fiberboard and news paper), because, for example, cardboard may be too rigid and paper may be too flexible/compliant to undergo the molding and/or thermoforming process desired. Any of the materials that may be used to form the dispenser case may be used in any of the embodiments described herein. Any discussion of pulp herein may also apply to any of the materials (e.g., fiber molding, natural fibers, biodegradable or compostable materials) that may be used to form a dispenser case.

[0057] In some embodiments, the dispenser case may be formed from, or may include metal (such as aluminum, steel, iron, nickel, copper, brass, silver, gold) or alloys or combinations thereof. In additional alternative embodiments, the dispenser case may be formed from or may include plastics and/or polymers, or combination of polymer and agri fiber, either recycled or virgin. For example, the dispenser case can be plastic or may include a thermo formed plastic/film for barriers or retaining portions of compartments, or further functions. In some embodiments, portions of the dispenser case may be separated at the end of use. For example, a plastic portion may be separated from a pulp portion of the dispenser.

[0058] The dispenser case may be formed from moldable materials. The dispenser case may be formed from materials that may be, for example, molded at elevated temperatures, such as temperature of about 100 °C, or 110 °C, or 120 °C, or 130 °C, or 140 °C, or 150 °C, or 160 °C, or 170 °C, or 180 °C, or 190 °C, or 200 °C, or 210 °C, or 210 °C, or greater, which may be appropriate for high-impact polystyrene (HIPS), high-density polyethylene (HDPE), acrylonitrile butadiene styrene (ABS), and other polymeric and non-polymeric materials. The materials may be allowed to cool such that a desired shape sets in. This forming can take place by a process called thermo forming, where a material is heated to pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product. Thermo forming may take place with heated film and tools that are cool relative to the heated film and encourage cooling. With pulp thermo forming, forming may take place with the aid of, for example, hot tools. In one example of pulp thermo forming, pulp slurry passes through a tool with a mesh surface shaped as the desired part(s) and this wet shaped part is transferred to a heated shaped tool using a matched die transfer tool and compressed with a matched shape tool where the tools are hot. The combination of heated tools heated to a temperature of 150 °C, 200 °C, 250 °C, 300 °C, or greater, vacuum draw that removes moisture and steam away from the part through the tool, and compression of the matched tools onto the formed pulp shape, may serve to shape the part according to the negative space between the matched tool. In some embodiments, ultrasonic, agitation, microwaves, vacuum in combination is positive pressure air, and other ways than heat may be used to remove moisture, or may be in used in combination with heat to remove moisture. There can be a series of compressive phases with increasing levels of compression. The method may allow for a formation of a dispenser case that may be usable as-is, e.g., without any dispenser insert or dispenser frame features. In example, the dispenser case may be molded into a clamshell structure, such that it may be closable and, optionally, filled with sachets. In another example, the dispenser case may be molded into two opposing complementary pieces, such as hemispheres, which may be connectable and closable so as to create a container for holding sachets within. The dispenser case may be opened and closed repeatedly to remove or add sachets as needed.

[0059] The molded material may also be foldable. In an example, the molded material may be formed into a flat structure. After cooling, the flat structure may be folded so as to create a closable dispenser case may, which may, for example, have a clamshell structure once folded. Such a dispenser case may be closed and, optionally, filled with sachets.

[0060] A dispenser case may be molded in a single piece with desired features. The dispenser case may be molded with integral hinges, integral registration/interlock features (e.g., latches, dividers, or zones within the case). Such features, e.g., latches, may aid in locking the dispenser so that items can be held within, while the hinges may aid in making it closeable. The dispenser case may include pulp-molded dividers that are integrally formed. The molded-in dividers may aid in separating items within the dispenser case, e.g., keeping sachets containing different types of materials separated into different compartments, or keeping sachets apart for easier selection and removal. A dispenser case may be molded with smooth shapes, such as soft or curved edges, such that the dispenser case may not cause damage to other items or cause injuries. A dispenser case may be molded to have elevated or "three-dimensional" features, such as raised buttons, logos, or features that provide depth or cavities within the case.

[0061] In another example, two or more parts of the dispenser case may be molded separately and then connected to one another via additional structures, such as hinges and/or fasteners. In such cases, the additional structures can hold together the two or more parts of the dispenser case such that the case may, for example, be closeable. The two or more parts of the dispenser may form a clamshell or other closeable structure with the aid of the additional structures.

[0062] A molded dispenser case with or without any additional structures may comprise a plurality of sachets within it. The dispenser case may comprise a first portion and a second portion joined at a first mating point. In an alternative embodiment, the dispenser case is a single piece. In an embodiment, the dispenser case includes features that facilitate

deconstruction or separation of the dispenser case from the sachet. In an embodiment, the dispenser case is a molded fiber dispenser case. In another embodiment, the dispenser case is a pulp-formed dispenser case. In still another embodiment, the dispenser case can be formed of a fibrous material (e.g., natural fibers), biodegradable material, or compostable material. In an embodiment, the sachets can be formed of a polymer or polymeric material, such as a flexible polymer. In an embodiment, the sachet can be formed of an optically transparent material.

[0063] A dispenser may include a dispenser case and sachets. In one configuration, the dispenser case has a clamshell-type shape, which can be formed in an open position, but may optionally be closeable. The dispenser case can have one or more hinges that allow for opening and closure of the dispenser case. The dispenser case can be closed around the sachet. The dispenser case can have snap or interlock features positioned along open edges of the dispenser case to provide or assist with providing full and secure closure about the sachets. The dispenser case can also have features, such as ribs or reinforcements, to securely support the sachets. The dispenser can be opened by an end user to remove the sachets, either for the purpose of removing sachets for use or for the purpose of reloading the dispenser (e.g. replacing empty sachets with full sachets). The dispenser can be dismantled such that the dispenser case can be reused. The dismantling of the dispenser can be performed such that the dispenser case is not destroyed or destructed. The dispenser case can be configured for reclosure after opening and/or reloading the dispenser. The dispenser case can be reclosed using latches, hinges, adhesive, labels, elastic strap, or any other manner.

[0064] The dispenser case may also include features that may provide for evidence of tampering. For example, the dispenser case may include a seal or locking mechanism that may be broken once the case is even partly opened, such that a user may become aware that the dispenser case has been tampered with. In some cases, the dispenser case may be equipped with a transparent material, such as glass of a transparent plastic, such that the contents of the case, including sachets, could be viewed without opening the dispenser case and breaking the seal or locking mechanism.

[0065] Outer surfaces of the dispenser case in accordance with the invention herein can comprise any structural body that provides an enclosure and support to sachets. The dispenser case can be formed of any material suitable for providing structural support. In some configurations, the dispenser case can have sufficient structural rigidity to provide a gripping or grasping area for a user's hand and/or to prevent compression of sachets contained within the dispenser case. The gripping or grasping area can be positioned on any part of the dispenser, and preferably at the location where the two parts of the dispenser are joined together (as in a briefcase). In other cases, the gripping or grasping area may be in the center of the dispenser case. In still other cases, the gripping or grasping area may be in several parts of the dispenser case.

[0066] In embodiments, each of the gripping areas can comprise 1 or more, or 2 or more, or 3 or more, or 4 or more, or 5 or more, or 10 or more, or 20 or more ridges. In addition, each of the gripping areas can comprise multiple sets of ridges. As an example, the first gripping area can include 3 ridges. In embodiments, each of the gripping areas can include 1 or more, or 2 or more, or 3 or more, or 4 or more, or 5 or more, or 10 or more, or 20 or more depressions. As an example, the first gripping area can include two adjacent depressions. The gripping areas can have any shape and configuration. As an example, the gripping areas can be circular, triangular or boxlike (e.g., elevated or "three-dimensional" features). In addition, the gripping areas can have any depth. In some cases, it might be desirable to have gripping areas with depressions and ridges in the depressions, such and the dispenser case may have molded depressions with molded ridges. The gripping areas can be positioned to

accommodate smoother surfaces that are defined to receive a graphic label. The gripping areas could be on the front of the dispenser, or back of the dispenser, or both front and back of the dispenser.

[0067] The dispenser case, which can be pulp molded, can have features that extend below or above a tool parting line, sometimes described as a parting line flange. In some cases, the molding can be performed in such a way that an edge of the dispenser case does not have a parting line flange. Any edge can be designed without a parting line flange. The absence of a parting line flange can allow for a flat surface to be formed when that edge is joined or abuts to another edge of the dispenser case that also does not have a parting line flange.

[0068] The features on the dispenser case may be of equal or unequal size, can be designed such that they overlap, or can be designed such that one feature inserts through a slot in the other feature. Overlapping features can allow for the two sides of the dispenser case to be secured to each other without adhesives. The features can be designed such that sides of the dispenser case are prevented from separating once one feature is inserted through a slot in another feature. For example, a first feature on one side of the dispenser case may be shaped like an arrowhead and a second feature on another side of the dispenser case can have a slot. The arrowhead shaped feature can be inserted through the slot of the second feature, where the arrowhead prevents the sides from becoming separated. Other shapes, such as hook- shapes, L-shapes, Y-shapes, and T-shapes, can be used to secure one feature to the other feature, such as at the closure point. The features can extend in the plane of the dispenser case portion that they originate from, or the features can extend in a plane other than the plane of the dispenser case portion that they originate from. Angled features can allow for a variety of locking shapes to be formed, such as hooks. In some embodiments, a locking mechanism may include a latch made by, for example, folding a sturdy material, such as cardboard. The features can be formed during the molding process and/or can be modified after pulp molding by folding or any other method known in the art. The feature may or may not need to be deformed to be inserted through the slot of the second feature. Overlapping features can allow for a flat surface to be formed from two pulp-molded parts, pieces, or halves. In some embodiments, the parting line flange, as described herein, can be formed internally, externally, or both internally and externally.

[0069] A dispenser frame may be connected to the dispenser case. A retaining collar may hold the dispenser frame/insert to the dispenser case. The retaining collar may provide a frictional fitting around both the dispenser case and the dispenser frame/insert.

[0070] The dispenser case can also comprise interlocks for connecting pieces of the dispenser case together or securing the dispenser case in a closed position. The dispenser case can also comprise openings for viewing the contents of the dispenser case. The openings or windows may be formed of a different material than the dispenser described herein.

The flanges and interlocks can be utilized in any dispenser described herein.

[0071] A wall of the dispenser may be integrally molded so as to include a double wall, including an inner wall and an outer wall. In some cases, the space between the two walls may be completely closed off, such that the empty space between two walls may, for example, provide cushioning for the dispenser case. In other cases, the double wall can be molded in such a way that the space between the walls is not completely closed off. In such cases, the double wall can function as an insert or a separator where, for example, sachets can be collected. In other cases, the opening between two walls may be filled with, for example, cushioning material such as foam, and the opening between the two walls may be sealed or covered with other material (e.g., a mesh cover), so as to keep the cushioning material in place.

[0072] In some cases, the inner part of the double wall may be molded separately from the outer part. In some cases, the inner part may be connected to the outer part by an adhesive, such as glue, or by a mechanism such as an interlock. An interlock may be formed of metal or other suitable material. In some cases, sachets or other items, including cushioning material, may be placed between the inner wall and the outer wall.

[0073] A dispenser may include supporting features, e.g., one or more ribs. Such ribs may provide more strength to the structure of the dispenser case. In some cases, the ribs may comprise the same materials as the dispenser case, such as a fiber or pulp-mold, and may be molded in the same piece as the dispenser case, while in other cases the materials may include different materials from the dispenser case or may be separate pieces that are adhered, attached, or integrated with the dispenser case. The ribs may include different arrangements and configurations that may lend support to the neck area of the dispenser. The ribs may be parallel to each other, may cross each other, or arranged in a random arrangement. The ribs may intersect, or they may not intersect. The ribs and dispenser can be shaped to allow for efficient nesting of open parts when stacked.

[0074] The dispenser case may be formed from one or more sheets of material that are laminated, folded or glued together. The sheets of material can comprise hinges, joints, creases, interlocks, flanges, or flaps for simplified folding of the sheets to form the dispenser case. Parts of the dispenser case may be hinged together or fashioned as separate front and back shells, which include a fitting that enables the two shells to close.

[0075] In some embodiments of the invention, the dispenser case comprises a fiber or pulp- molded body. The fiber and pulp-molded body can be a hollow shell, a clam shell, a two- piece shell, a multi-piece shell, or a combination thereof. The hollow shell can be a one-piece fiber or pulp-molded body where sachets are placed on the interior of the hollow shell through an opening of the hollow shell. The clam shell can be a fiber or pulp-molded body with a hinge. The hinge can be located on any side of the clam shell. For example, the hinge may be located along a bottom edge or side edge of the dispenser case. In another example, the clam shell can be formed from two halves without a hinge, with separate shells coming together. The clam shell and/or the sachets can have flanges and/or interlocks for securing the clam shell to or around the sachets. The two-piece shell can comprise two fiber or pulp- molded body pieces that can enclose sachets. The two pieces can have interlocks or flanges for securing the pieces to each other. The two-piece shell can be a two-part assembly of two cup-like parts that are assembled to one another with their open ends facing one another that can enclose sachets. A multi-piece shell can comprise a fiber or pulp-molded body piece with a hinge or a two-piece fiber or pulp-molded body combined with a belly band and/or an end cap for securing the multi-piece shell in a closed form around sachets. A multipiece shell may have multiple parts such as multiple hinges or multiple locking mechanisms. In some cases, this may allow for more than one access point or opening of the dispenser case. Pieces of the dispenser case can be held in place by an adhesive, a label, a mechanical deformation, or any other means known to those skilled in the art.

[0076] The dispenser case can be shaped for incorporation of functional features. In some embodiments of the invention, the dispenser case can comprise openings or cut-outs. The openings or cut-outs can be located on any side or surface of the dispenser case. The openings or cut-outs can provide multiple functions. These functions can include reducing the amount of material used to form the dispenser case, reducing the weight of the dispenser case, allowing for viewing of the contents of the dispenser, allowing for the positioning of stiffening rib features, retaining an interlock feature from another piece of the dispenser, providing features for enhancing the ability to grasp the dispenser case, providing features for separation from other parts of the dispenser, and increasing the ability to collapse or compress the dispenser case. The openings or cut-outs can be formed during molding of the dispenser case, or can be die-cut or water-cut after molding of the dispenser case.

[0077] Dispensers described herein, such as dispenser cases, can have a bending part or seam that allows the dispenser to be folded into a closed configuration. Dispensers may also include separate pieces that are glued or interlocked together. The edges of the one or more pieces of the dispenser may form a parting line. A parting line may be provided at an edge of the dispenser. In some instances, a parting line may be provided where one or more pieces come together, or where an edge of a folded piece contacts another edge of the folded piece. A parting line may be a tool parting line where the edge may have been provided in a mold when used to create a thermoformed dispenser case.

[0078] In accordance with some embodiments of the invention, the parting line may follow a parting line plane. In other embodiments, the parting line need not follow a plane and may deviate from a plane. In one example, a parting line and/or parting line plane may be provided at a lower portion of an edge of the dispenser piece and one or more features may extend beyond the parting line. In another example, the parting line and/or parting line plane may be provided at an upper portion of an edge of the dispenser piece and one or more dips may be provided below the parting line plane.

[0079] In some instances, one or more pieces may have a flap or extension extending over a parting line, where two or more pieces of the dispenser may come together. The flap or extension on a first piece may overlay a second piece of the dispenser case.

[0080] A parting line may have a flat edge, so that a side of the dispenser case is flat. One or more side of the dispenser case or portion of one or more side of the dispenser case may be flangeless. In other embodiments, one or more flange may be provided at an edge or parting line of the dispenser case. The dispenser case may be flat where one or more overlap may occur. In some embodiments, the overlap may occur all on the same side (e.g., one or more extending features from a first piece overlaps at least a portion of the second piece). In other embodiments, the overlap may occur on multiple sides (e.g., one or more feature from a first piece may overlap at least a portion of the second piece, and one or more feature of the second piece may overlap a portion of the first piece).

[0081] When a dispenser case is closed, one or more portion of a dispenser case may or may not overlap another portion. The dispenser case may be closed so that substantially no gaps are provided between the pieces. The dispenser case may be closed so that no sachets may escape the dispenser case.

[0082] In some embodiments of the invention, and as described elsewhere herein, a tamper- evident feature or seal that is sometimes coupled to a locking mechanism can be configured such that breaking, destruction or unsealing of the tamper-evident seal results in formation of an opening. The tamper-evident feature can be designed by selecting a tamper-evident feature that is attached to the dispenser case with an adherence, adhesive, or tear strength that is greater than the adherence, adhesive, or tear strength of the tamper-evident feature itself, such that the tamper-evident feature can be broken rather than removed from the dispenser case. A dispenser case may include a tamper-evident seal placed over an aperture of the dispenser. The tamper-evident seal can comprise a flap for facilitating removal of the tamper evident seal from the dispenser.

[0083] A dispenser case can provide support during shipping and handling. The dispenser case can be shaped for improved shipping or storage characteristics. The dispenser case can have a design such that the dispenser case can stack against other dispenser cases in a space- efficient manner. Further, a dispenser case may include cushioning material as described herein.

[0084] The dispenser case can comprise one or more openings for viewing the contents within the dispenser case. As described herein, the dispenser can also have a gripping or grasping area for gripping or grasping the dispenser by a user.

[0085] Stiffening protrusions for structural rigidity of the case, and other stiffening features such as ribs, gussets, tabs, flanges, and other details to provide may help structural integrity that allows for stacking of the dispenser, or to ensure that the shape of the dispenser case allows for stable stacking.

Dispenser frame and/or dispenser inserts

[0086] A dispenser frame may provide additional structural support to the dispenser case. The frame may be made of paper, cardboard, plastic, metal, or another suitable material. The dispenser frame may, for example, provide structural rigidity to the dispenser, and may be attached to the outside or inside surface of the dispenser. In some cases, the dispenser frame may provide a hinge or a locking mechanism. The dispenser frame may be mechanically attached through robust means, such as ultrasonic welding, heat sealing or other methods familiar to anyone skilled in the art, including adhesive, mechanical connection, or interlocking. When it is made from a different material than the dispenser case, the dispenser frame may also provide other benefits, such as a material that can be recycled together with the dispenser case material but having some different properties from the dispenser case material, which may offer some benefits. For example, the frame may include a material that is tougher (e.g., cardboard) than the dispenser case material, which may make it more useful as a hinge. In addition, the dispenser frame material may enable function such as scoring, hinges, folds, tabs, diecut tab receivers, and catches.

[0087] Dispenser inserts may provide additional structure and compartmentalization on the interior part of the dispenser case. Dispenser inserts may be formed of paper or card stock, such that, for example, it is possible to print on the inserts. Dispenser inserts may also be formed of plastic or polymeric materials, as described herein. Dispenser inserts may be die- cut to complex shape, have folds, and have properties of paper. Dispenser inserts may be foldable, and may function as dividers. In some cases, inserts functioning as dividers may separate different types of sachets from one another. In some cases, the dividers or inserts may help hold sachets in place. The inserts may help configure the dispenser case to carry different size and number of sachets in the different compartments created by the inserts. Dispenser inserts may extend beyond the perimeter of the case to have function features such as hang tags, tamper evident seals, tear-aways, and graphic surfaces.

[0088] Optionally, dispenser inserts may connect to a dispenser case section or shell mechanically. In some instances, the dispenser inserts may be connected without requiring an adhesive. In some instances, the dispenser inserts may be connected via pressure fit connection.

[0089] In some embodiments, dispenser frames may be a type of dispenser insert.

[0090] In some cases, dispenser inserts may be formed from polymers that belong to a group of polymers that may be recycled together, or formed from the same type of polymer. Formation from the same type of polymer or from polymers belonging to one recycling group can allow for simplified and/or reduced-cost recycling. A type of polymer can comprise polyethylene terephthalate (PET), high-density polyethylene (HDPE), polyvinyl chloride (PVC), low density polyethylene (LDPE), polypropylene (PP), polystyrene (PS), and other polymers. The polymer can be an FDA-approved plastic. The recycling groups can comprise plastic identification codes 1, 2, 3, 4, 5, 6, and 7. A recycling group can comprise a set of plastic or polymer types that can be recycled together using a recycling process that does not require separation of the plastic or polymer types prior to the recycling process.

[0091] In some cases, the inserts may be welded to the dispenser case. In other cases, the inserts may be attached to the dispenser case by an adhesive force, such as with the aid of glue. In still other cases, the inserts may be attached to the dispenser case via a locking mechanism. Dispenser inserts may also be attached to the dispenser case via elastic banding, adhesive or non-adhesive tape or film, cord, metal banding, heat-shrink tubing, adhesive or non-adhesive paper labels, sealing wax, friction fit and so on.

[0092] Dispenser inserts can be molded with the dispenser case during the molding process. Dispenser inserts can be placed in the mold prior to formation of the dispenser case. The parts to be insert molded can be placed into the pulp forming machine by hand, mechanically, or robotically. Once the dispenser case is formed, the dispenser insert is integrated with the dispenser case and removed from the mold with the dispenser case. The dispenser insert can be any type of material. For example, it can be plastic, pulp, paper, cardboard, metal, or glass. The dispenser insert can be the same type of material as the dispenser case. In an

embodiment, the insert molded part can be made of Type 3 pulp thermo forming, and the resulting detailed pulp parts can be placed in a Type 2 forming machine for molding of the inserted part, resulting is a detailed area integrated to a less detailed part. With the difference in cost between the two processes the final part can be more cost effective that an entirely Type 3 part, yet still have optimal detail and tolerance where desired. Dispenser inserts may be separated from the dispenser case by a user, which can allow for proper separation of materials for recycling, disposal, or reuse. Dispenser inserts can also increase the stability or rigidity of the dispenser case. For example, dispenser inserts can be designed such that they reinforce the base, sidewalls, or neck area of the dispenser case. Dispenser inserts can be a solid piece with or without an aperture. In some cases, dispenser inserts may function as pockets.

[0093] Dispenser inserts made of material such as die-cut paper may perform other functions in conjunction with the dispenser case. They may be adapted for hinging, hinge receiving, latching, and other functions. In some cases, dispenser inserts may perform substantially the same functions as the dispenser frames. In some cases, dispenser cases are further adapted with cartridges for holding sachets, with the cartridges performing the same functions as the dispenser inserts (e.g., compartmentalizing or separating sachets). In some cases, the dispenser inserts and dispenser frame are made of the same material. In other cases, the dispenser inserts and dispenser frame are made of different materials. In some cases, inserts may be separate pieces from the dispenser case. In other cases, dispenser inserts and dispenser case may form an integral single piece. An integral single piece with a dispenser case may be molded or folded in such a way as to create a dispenser case component and a dispenser insert/divider component. [0094] In some cases, a part of the locking functionality may be located on the dispenser case, while another part of the locking functionality may be located on the dispenser frame. In some cases, the dispenser case and the dispenser frame are made of different materials.

[0095] In some cases, a retaining collar may be placed around the dispenser case. The retaining collar may include a snap member. The snap member may be a protrusion from a surface of the retaining collar. The retaining collar may be formed of a polymeric material, such as a plastic, or a composite material, which may include one or more of a metal, plastic or cellular material, such as pulp. The retaining collar may be a band of shrink sleeve material which shrinks with heat applied during assembly. The retaining collar may also be formed of paper, pulp, plastic, cardboard, metal, or another suitable material, as described herein. In its shrunken state, the band may serve to unify the dispenser case parts.

[0096] The dispenser frame/insert and dispenser case can be recycled after use. The dispenser frame can be designed such that it, as a paper component, it can be recycled together with the dispenser case material. The dispenser can be designed such that the dispenser frame/insert and the dispenser case can be separated prior to being subjected to a recycling process or prior to disposal. The dispenser frame/insert and dispenser case can also be refilled and reused. The sachets can be separated from the dispenser case without damaging or destructing the dispenser case and/or dispenser frame/insert.

[0097] Separation of the dispenser frame/insert and the dispenser case can be facilitated by a minimization of attachment points between the dispenser frame/insert and the dispenser case. In some embodiments of the invention, the attachment points are weakened to allow for breakage. Separation of the dispenser frame/insert and the dispenser case can improve the ability and/or ease of recycling the dispenser by a given recycling process. In some cases, inserts may be removable reversibly from the dispenser case. In an example, the inserts may be re-attached to the dispenser case after separation. In other cases, inserts may not be re- attachable to the dispenser case after separation.

[0098] Dispenser case has features that facilitate deconstruction or separation of the dispenser case from the dispenser frame/inserts. Such features may include holes, tabs, perforations, tear-away strips, pull-strips, creases, labels, embedded pieces of string or other features as might be conceived by those skilled in the art. A user can insert a finger or other object into a hole for destruction of the dispenser. Alternatively, a pull-strip can be pulled to cause destruction of the dispenser. The pull strips could be made of a higher density paper or organic compostable string. The pull strip could be insert molded, over molded or added after molding of the dispenser case. User interaction with said features can cause the dispenser case to become damaged or separated from the dispenser frame/inserts to such an extent that the two parts are no longer connected. Once separated, the parts can be directed to the correct recycling streams.

[0099] In some embodiments of the invention, the amount of material used to construct the hybrid dispenser is minimized for a given dispenser volume. The minimization of material used for construction of the dispenser can reduce the waste associated with production or disposal of the dispenser.

[00100] Portions of the dispenser can be formed from polymers belonging to one recycling group or are formed from the same type of polymer. Formation from the same type of polymer or from polymers belonging to one recycling group can allow for simplified and/or reduced-cost recycling. A type of polymer can comprise polyethylene terephthalate (PET), high-density polyethylene (HDPE), polyvinyl chloride (PVC), low density polyethylene (LDPE), polypropylene (PP), polystyrene (PS), and other polymers. The polymer can be an FDA-approved plastic. The recycling groups can comprise plastic identification codes 1, 2, 3, 4, 5, 6, and 7. A recycling group can comprise a set of plastic or polymer types that can be recycled together using a recycling process that does not require separation of the plastic or polymer types prior to the recycling process, e.g., separation of the dispenser case material and dispenser insert material.

[00101] Dispensers of embodiments of the invention can be designed to minimize materials cost, thus aiding in the reduction of post-use waste. In addition, materials can be selected so as to minimize environmental impact. For example, the dispenser case can be formed of a biodegradable material.

[00102] Closures, which may be used for reversible closure and opening of a dispenser case, may include one or more parts or features that are complementary to one or more features or parts on the dispenser case or dispenser inserts. Closures can be integrally formed, adhered, folded over, or welded or otherwise attached to the dispenser insert or frame. Closures can be formed from recyclable, biodegradable, or compostable material. A closure may comprise a twist cap, snap cap or lid. Dispenser inserts can mate to a closure on a case by friction, mechanical deformation, heat stakes, snaps or locks, or any other manner described herein or known to one skilled in the art, including magnetically, via a hook-and-loop setup (e.g., with Velcro), by folding the insert over a shell, and with adhering material.

[00103] In some cases, the attachment members, including posts, may be formed from the closure. That is, the attachment members may be unitary (or single-piece) with the closure. For example, the closure and attachment members may be formed from a polymeric material, such as a plastic. The closure and attachment members may be formed by injection molding or extrusion. In other cases, the attachment members may be formed from one or more materials separate from the closure. For example, the closure may be formed of a first polymeric material and the attachment members may be formed of a second polymeric material, a metallic material (e.g., aluminum), or a composite material that may include one or more of a polymer and metal.

[00104] Closures that can be attached to a dispenser case using heat stakes. The heat stakes can extend from the closure and through a dispenser case. The dispenser case can have predrilled, preformed or premolded holes, die-cut holes, slots, or slits that allow for the heat stakes to extend through the dispenser case or the heat stakes can be made to pierce through the dispenser case or through a molded feature in the dispenser case or through a thinner area in the dispenser case. The heat stakes can be arranged in a circumferential or radial manner about the closure, or can be positioned only partially about the closure. The closure can be attached to the dispenser case by about, less than about, or at least about one, two, three, four, five, six, seven, eight, nine, ten, or more stakes. The stakes can be made from a material that is the same or different from rest of the closure. For example, the stakes can be made of the same plastic as the closure. The heat stakes can be integral to the closure. The stakes can be made of a plastic that can be melted or deformed by heat or by ultrasonic energy directors. Melting or deformation of the plastic can allow for secure attachment between the closure and the dispenser case. The melted or deformed stakes can form any shape. For example, the melted or deformed stakes can form a rivet shaped head. In certain embodiments, the closure can be mated to the dispenser case or a part of the dispenser case dispenser case through a hole that is in the dispenser case part. The closure can then be inserted from the inside and connected to the dispenser case dispenser case with, e.g., adhesive, mechanical deformation of the pulp to the closure flange, with the aid of welding, and/or a retaining ring installed from the outside.

[00105] A closure can be attached to the dispenser case by flanges. The flanges can be friction fit to the dispenser case. The flanges can also be glued or otherwise attached to the dispenser case by an adhesive. In some embodiments, the closure is attached to the dispenser case without the use of adhesives or glues. Closure or locking mechanism that is attached to a dispenser case by attachment members (also "external mating features" herein) that may be a mechanical deformation of flanges in accordance with an embodiment of the invention. The mechanical deformation can be performed by a machine or manually. The flange can mechanically deform in a circumferential manner about the closure, or only partially about the closure. In some embodiments, the mechanical deformation may cause a mechanical deformation of only the closure, only the dispenser case, or both the closure and the dispenser case. The mechanical deformation may be reversible or irreversible.

[00106] FIG. 1 shows a dispenser case 100 having one or more dispenser inserts 110a and 110b. Inserts may be integrally molded with the dispenser case or may be detachable, and may be formed from the same or different materials as the dispenser case. In some instances, the dispenser case may have a clamshell configuration having a first shell 120a and a second shell 120b. A shell may have a hinge integrally formed with the first shell and a second shell. Alternatively, a separate hinge may be provided as a separate, detachable piece. The hinge may be formed of the same or different material as the shells. Shells 120a and 120b may be formed of thermoformed material, e.g., thermoformed pulp. One or more sachet 130 may be held by the dispenser case. In some embodiments, one or more sachet may be held within only a single shell, or side, of the dispenser case. Alternatively, one or more sachets may be held within both shells, or sides, of the dispenser case. A part of a sachet may extend beyond the insert, as shown, or may be completely behind the insert.

[00107] The dispenser case may further include a locking mechanism such as a hook or latch 140, which may be integrally formed or molded with the dispenser case, or may be a part of the one or more inserts (which in turn may be formed or molded with the dispenser case, or may be detachable), or a part of a different structure such as dispenser frame. An opening 150, which may be integrally molded with the dispenser case or may be a part of a detachable insert or dispenser frame, may mate with the hook or latch 140 to form an interlock. Latch 140 and opening 150 may be formed of thermoformed material, such as thermoformed pulp. A latch and/or opening may be provided on a side opposite the hinge. A dispenser case may be configured to have an open position and a closed position. When the dispenser case is in a closed position, a hinge may be provided on a side with a locking mechanism on an opposing side. A latch and/or opening of a locking mechanism may interlock or interact. One or multiple locking mechanisms may be provided on a side, or on multiple sides. When a dispenser case is in a closed position, one or more objects held therein may not be able to escape. When a dispenser case is in an open position, the one or more objects therein may be accessed and/or removed. The hinge can be along any edge of the dispenser. Multiple small hinges can run along and edge. The dispenser case may bend along the hinge in order to be in the open and/or closed positions. In an alternative embodiment, a hinge need not be provided. In one example one or more locking mechanisms may be provided on opposing sides of the dispenser case. [00108] FIG. 1 also provides top views 160a and 160b of the dispenser case and side views 170a and 170b of the dispenser case, in the closed configuration.
