RELATED APPLICATIONS

The present application claims priority under 35 U.S.C. § 119 to U.S. Provisional Application No. 62/898,117, entitled “Biodegradable Cooler”, filed on September 10, 2019, the entirety of which is incorporated by reference herein.

TECHNICAL FIELD

The present disclosure relates generally to coolers, and more particularly, to a cooler with carry handle made of a biodegradable material.

BACKGROUND

Coolers, ice chests, ice boxes, or the like are commonly used to store contents (e.g., food, beverages, etc.) and keep the contents cool. While many coolers are constructed using durable materials intended for repeated use, other coolers have been manufactured to be disposable. Coolers of the disposable variety are conventionally made from polystyrene foam (i.e., Styrofoam).

The use of polystyrene is problematic because it is a non-biodegradable solid. Disposal of polystyrene coolers, consequently, can cause significant environmental harm as discarded polystyrene will persist in the environment for centuries. Many cities and counties across the United States have passed regulations banning sale of polystyrene products for this reason.

Further, many coolers of the disposable variety generally use indentations created in the walls of the cooler. These indentations require users to use both hands in transporting the cooler from one place to another, thereby not allowing the user to have a free hand in carrying other items. Thus, a cooler that is made from a biodegradable material and that has a handle that allows users to carry the cooler with just one hand may be desirable. BRIEF DESCRIPTION OF THE DRAWINGS

FIGS. 1 A and IB show perspective views of a biodegradable cooler 100 with a handle according to an embodiment. In some example embodiments, the biodegradable cooler 100 includes an outer shell 102 and a liner (shown in FIGS. 3 and 4) that is disposed within the outer shell 102. The outer shell 102 may include a base 104 and support walls including a side wall 106 , an end wall 108, a side wall 110, and an end wall 112. The support walls may each be coupled to the base 104 and may extend up from the base 104. For example, the side wall 106 and the side wall 110 may extend up from the base 104 at opposite sides of the base 104 from each other, and the end wall 108 and the end wall 112 may extend up from the base 104 at opposite sides of the base 104 from each other. To illustrate, the end walls 108, 112 are coupled to and extend between the side walls 106, 110 at opposite ends of the base 104. In some example embodiments, the support walls including the side wall 106, the end wall 108, the side wall 110, and the end wall 112 may be continuously and seamlessly coupled to the base 104. In some example embodiments, all of the side wall 106, the end wall 108, the side wall 110, and the end wall 112 may extend up vertically from the base 104. Alternatively, one or more of the side wall 106, the end wall 108, the side wall 110, and the end wall 112 may extend up from the base 104 at a slightly slanted angle from the vertical. For example, the side walls 106, 110 may be slanted outwardly away from each other as the side walls 106, 110 extend up from the base 104 at opposite sides of the base 104, and the end wall 108 and the opposite end wall may extend up vertically or at a slightly slanted angle.

In some example embodiments, the outer shell 102 may also include roof sections 114, 116, 118 and another roof section opposite the roof section 116. To illustrate, all roof sections of the outer shell 102 including the roof sections 114, 116, 118 may be coupled to and extend from a respective one of the support walls. For example, the roof section 114 and the base 104 may be coupled to the side wall 106 at opposite ends of the side wall 106, and the roof section 116 and the base 104 may be coupled to the side wall 110 at opposite ends of the side wall 110. In some example embodiments, the base 104 and the roof section 118 may be coupled to the end wall 108 at opposite ends of the end wall 108, and the base 104 and the roof section that is opposite the roof section 118 may be coupled to the end wall 112 at opposite ends of the end wall 112. When the outer shell 102 is closed as shown in FIGS. 1A and IB, the roof sections 114 and 116 may be slanted toward each other as each roof section 114, 116 extends up from the respective side wall 106 or 110. As shown in FIGS. 1 A and IB, the roof section 114 and the roof section 116 may form a tent-top shape when the outer shell 102 is closed. For example, when the outer shell 102 is closed, the perimeters of the roof section 114, the end wall 108, and the roof section 116 may form a triangular shape as more clearly shown in FIG. 1 A. Similarly, the perimeters of the roof section 114, the end wall 112, and the roof section 116 may form a triangular shape. The roof section 118 and the roof section that is opposite the roof section 118 may also be slanted toward each other when the outer shell 102 is closed as shown in FIGS. 1 A and IB.

In some example embodiments, some or all of the roof sections of the outer shell 102 including the roof sections 114, 116, 118 may be continuously and seamlessly coupled to the respective one of the support walls. For example, the roof section 114 may be continuously and seamlessly coupled to the side wall 106. Similarly, the roof section 116 may be continuously and seamlessly coupled to the side wall 110. The roof section 118 may be similarly continuously and seamlessly coupled to the end wall 108, and the roof section that is opposite the roof section 118 may be continuously and seamlessly coupled to the end wall 112

In some example embodiments, the outer shell 102 includes handle sections 120, 122. For example, the handle section 120 may be coupled to and extend up from the roof section 114, and the handle section 122 may be coupled to and extend up from the roof section 116. To illustrate, the handle section 120 and the handle section 122 are attached to each other when the outer shell 102 is closed as shown in FIGS. 1A and IB. The outer shell 102 may be kept closed by a handle flap 126 of the handle section 120 that extends through a handle opening 124 and wraps over a portion of the handle section 122. Alternatively or in addition, the outer shell 102 may be kept closed using one or more fasteners (e.g., snap fasteners), clips, Velcro, and/or other means as can be readily contemplated by those of ordinary skill in the art with the benefit of this disclosure.

In some example embodiments, the outer shell 102 includes the handle opening 124 for inserting, for example, a hand therein to carry the cooler 100. For example, an opening in the handle section 120 may be at least partially aligned with an opening in the handle section 122 to provide the handle opening 124. The handle section 120 may be continuously and seamlessly coupled to the roof section 114, and the handle section 122 may be continuously and seamlessly coupled to the roof section 116. In some alternative embodiments, the handle opening 124 may have a different shape and/or different dimensions than shown in FIGS. 1 A and IB without departing from the scope of this disclosure. For example, the handle opening 124 may be circular, rectangular, etc. As another example, the handle opening 124 may be narrow, wider, longer, or shorter than shown.

In some example embodiments, the support walls (i.e., the side wall 106, the end wall 108, the side wall 110, and the end wall 112) and the roof sections 114, 116, 118, and the roof section opposite the roof section 118 may define a cavity of the outer shell 102 as more clearly shown in FIGS. 2 A and 2B. In some example embodiments, the outer shell 102 may be made from one or more biodegradable materials. In some example embodiments, the outer shell 102 may be made from a corrugate material such as a recycled corrugate material using methods known to those of ordinary skill in the art with the benefit of this disclosure. In some example embodiments, the outer shell 102 may include a material that is not biodegradable.

In some alternative embodiments, the outer shell 102 may have a different shape than shown without departing from the scope of this disclosure. In some alternative embodiments, the sections of the outer shell 102 may have different dimensions and/or different relative dimensions with respect to each other than shown without departing from the scope of this disclosure. For example, the handle sections 120, 122 may be vertically shorter or longer than shown. As another example, some or all of the roof sections including the roof sections 114, 116 may be slanted more or less than shown without departing from the scope of this disclosure.

FIGS. 2A-2C show different views of the outer shell 102 of the biodegradable cooler 100 of FIG. 1 A according to an example embodiment. Referring to FIGS. 1 A-2C, in some example embodiments, the outer shell 102 includes the base 104 and the support walls including the side wall 106, the end wall 108, the side wall 110, and the end wall 112. The outer shell 102 may further include the roof sections 114, 116, 118 as well as a roof section 202 that is located opposite from the roof section 118. The roof sections 114 and 116 are located opposite from each other.

In some example embodiments, the roof section 118 may include outer areas 206, 208 and a middle area 204 that is between the outer areas 206 and 208. The outer area 206 may have a triangular shape and may border the roof section 114. The outer area 208 may have a triangular shape and may border the roof section 116. When the outer shell 102 is closed, the outer area 206 may overlap a portion of the roof section 114, and the outer area 208 may overlap a portion of the roof section 116. When the outer shell 102 is closed, the middle area 204 may provide a cover to a cavity 214 of the outer shell 102 as more clearly shown in FIG.

1 A. The support walls (i.e., the side wall 106, the end wall 108, the side wall 110, and the end wall 112) and the roof sections 114, 116, 118, 202 may define the cavity 214 of the outer shell 102.

In some example embodiments, the roof section 202 may have similar areas as the roof section 118. For example, when the outer shell 102 is closed as shown in FIG. 1 A, the outer areas of the roof section 202 may overlap the roof section 114 and the roof section 116 in a similar manner as the outer areas 206, 208 of the roof section 118. When the outer shell 102 is closed as shown in FIG. 1 A, the middle area of the roof section 202 may provide a cover to the cavity 214 of the outer shell 102 in a similar manner as the middle area 204 of the roof section 118.

As more clearly shown in FIGS. 2A-2C, the handle section 120 is coupled to and extends up from the roof section 114, and the handle section 122 is coupled to and extends up from the roof section 116. As more clearly shown in FIGS. 2A and 2B, in contrast to the handle sections 120, 122 that extend up from the roof sections 114, 116, the outer shell 102 may not include handle sections that extend up from the roof sections 118, 202.

In some example embodiments, the handle section 120 includes an opening 210, and the handle section 122 includes an opening 212. For example, the opening 210 may be formed by partially cutting through an area of the handle section 120 to form the handle flap 126, and the opening 212 may be formed by cutting out an area of the handle section 122. When the outer shell 102 is closed as shown in FIGS. 1A and IB, the openings 210 and 212 may at least partially overlap with each other to provide the handle opening 124, and the handle flap 126 may be pushed through the handle opening 124 and folded back toward the handle section 122 to retain the outer shell 102 closed.

In some example embodiments, the base 104 of the outer shell 104 may be formed from multiple bottom flaps 220-226 as more clearly shown in FIG. 2C. For example, the bottom flaps 220-226 may be folded up and interlocked forming the base 104 such that the outer shell 102 is closed by the base 104 on a bottom end when the outer shell 102 is oriented as shown in FIGS. 2 A. In some alternative embodiments, the bottom flaps 220-226 may be interlocked in a different configuration than shown in FIG. 2C. In some alternative embodiments, the outer shell 102 may include fewer than four bottom flaps without departing from the scope of this disclosure.

In some alternative embodiments, the relative sizes of the different areas of the roof section 118 may be different than shown without departing from the scope of this disclosure some alternative embodiments, the openings 210, 212 may have different shapes and/or dimensions than shown without departing from the scope of this disclosure.

FIGS. 3 A and 3B show different views of the liner 302 of the biodegradable cooler 100 of FIG. 1 A according to an example embodiment. Referring to FIGS. 1 A-3B, in some example embodiments, the liner 302 is sized to be positioned in the cavity 214 of the outer shell 102. The liner 302 may include a bottom wall 304 and side walls 306, 308, 310, 312. The side walls 306-312 are coupled to and extend up from the bottom wall 304 such that the bottom wall 304 and side walls 306-312 define a cavity 314 of the liner 302. The side walls 306 and 310 are coupled to the side wall 308 at opposite sides of the side wall 304, and the side walls 306 and 310 are coupled to the side wall 312 at opposite sides of the side wall 312.

In some example embodiments, all of the side walls 306-312 may extend up vertically from the bottom wall 304. Alternatively, one or more of the side walls 306-312 may extend up from the base 104 at a slightly slanted angle from the vertical. For example, the side walls 306, 310 may be slanted outwardly away from each other as the side walls 306, 310 extend up from the bottom wall 304 at opposite sides of the bottom wall 304, and the side walls 308, 312 may be slanted outwardly away from each other as the side walls 308, 312 extend up from the bottom wall 304 at opposite sides of the bottom wall 304.

In some example embodiments, the liner 302 may include a lip 316 that extends outwardly from the walls 306-312 at a top end of the liner 302. For example, the lip 316 may provide a surface for holding the line 302 when inserting and removing the liner 302 into and out of the outer shell 102. In some example embodiments, the liner 302 may also include indentations such as an indentation 318 formed in the side wall 308. For example, the indentations may provide added ease of carrying the liner 302. In some alternative embodiments, the lip 316 and/or the indentations, such as the indentation 318, may be omitted without departing from the scope of this disclosure.

In some example embodiments, the liner 302 may be entirely seamless. In general, the liner 302 may be made in various sizes compatible with the outer shell 102. That is, the liner 302 may be sized to fit inside the cavity 214 of the outer cooler 102 while allowing the liner 302 to be conveniently inserted into and removed from the cavity 214. For example, the liner 302 may have a larger size when the outer shell 102 is correspondingly larger, and the liner 302 may have a smaller size when the outer shell 102 is correspondingly smaller. In some example embodiments, the liner 302 may be made to have a rigidity such that the side walls of the liner 302 do not collapse.

In some example embodiments, the liner 302 may be made from a pulp-based material using a method such as, for example, molding, etc. Pulp, as is generally known in the art, is a fibrous material prepared by chemically or mechanically separating cellulose fibers from wood, recycled paper, straw, grass, or other raw fibrous materials. Pulp is understood to be more eco-friendly than polystyrene, as pulp can be biodegradable (i.e., capable of disintegrating into an innocuous material), recyclable (i.e., capable of being reused or treated for reuse), and/or compostable (i.e., capable of decomposing within 90-180 days), without release of toxic residues upon decomposition.

In some cases, the pulp-based material from which the liner 302 is made can be derived entirely from pre-consumer recycled paper. In other cases, the pulp-based material from which the liner 302 is made can derive from a combination of the recycled paper and a wax additive (e.g., paraffin wax) added to enhance the water resistance of the liner 302. In yet other cases, a small amount of rosin (a solid form of resin) can be added to the pulp-based material to enhance the cooler’s durability. It is understood, however, that the pulp-based material can be derived from any suitable pulp-producing materials generally known in the art. Additionally, the liner 302 can be formed from other biodegradable materials such as paper, sugar cane, hemp, jute, bamboo, and other similar type materials. In some example embodiments, the outer shell 102 may be made from a biodegradable such as a pulp-based material and/or other biodegradable materials such as paper, sugar cane, hemp, jute, bamboo, and other similar type materials.

FIG. 4 shows the liner 302 of FIG. 3A prior to being inserted in the cavity 214 of the outer shell 102 of FIGS. 2A-2C according to an example embodiment. Referring to FIGS.

1 A-4, in some example embodiments, the liner 302 may be inserted in the cavity 214 of the outer shell 102 as illustrated by an arrow 402. For example, the cavity 314 of the liner 302 may be filled with items before the liner 302 is inserted in the cavity 214 of the outer shell 102. Alternatively, items may be placed in the cavity 314 of the liner 302 after the liner 302 is inserted in the cavity 214 of the outer shell 102. For example, items that need to be kept cold may be placed in the liner 302.

In general, the cooler 100 may be made by manufacturing the outer shell 102 to have a desired dimensions. For example, the outer shell 102 may be made from a recycled corrugate material or from another biodegradable material. The liner 302 may be manufactured to have dimensions such that the liner 302 fits in the cavity 214 of the outer shell 102. For example, the liner 302 may have the height H such that the top end of the liner 302 is below the roof sections 114, 116, 118, 202 and at or below the top end of the support walls (i.e., the side wall 106, etc.). To illustrate, the liner 302 may have the height H such that the roof sections 114, 116, 118, 202 of the outer shell 102 may be slanted to cover to the cavity 214 of the outer shell 102 as shown in FIG. 1 A without interference by the liner 302.

In some example embodiments, after providing the outer shell 102 and the liner 302, the liner 302 may be inserted into the cavity 214. After the liner 302 is inserted in the cavity 214 of the outer shell 102, some items (e.g., ice, bottled drinks, etc.) may be placed in the cavity 314 of the liner 302. Alternatively, the items may be placed in the cavity 314 of the liner 302 before inserting the liner 302 in the cavity 214. After the liner 302 containing desired items is in place in the cavity 214 of the outer shell 102, the outer shell 102 may be closed by pushing the roof sections 114 and 116 toward each other until the handle sections 120 and 122 come in contact with each other and while slightly pushing the roof sections 118 and 202 inward toward each other. For example, the roof section 118 may be partially folded along creases 216, 218 as the middle area 204 of the roof section 118 is pushed inward, and the roof section 202 may be partially folded along similar creases as a corresponding middle area of the of the roof section 202 is pushed inward. The roof sections 114, 116, 118, 202 provide a cover to the cavity 214 of the outer shell 102 when the handle sections 120 and 122 are in contact with each other.

In some example embodiments, the liner 302 may be removed from the cavity 214 of the outer shell 102 by first opening the outer shell 102, for example, by pulling the handle sections 120 and 122 away from each other. For example, the liner 302 may be pulled out of the cavity 214 of the outer shell 102 by placing fingers between the liner 302 and the side walls 114, 116 and pulling the liner 302 upward.

In general, the biodegradable cooler 100 described herein can be made of a biodegradable material, such as a pulp-based material, that is compostable, recyclable, and/or biodegradable. As a result, the cooler can be disposed in an eco-friendly manner in which the cooler disintegrates in a compost environment rapidly relative to conventional polystyrene coolers and without leaving toxicity into the soil. The biodegradable material, such as a pulp-based material, used for fabricating the cooler described herein can comply with modern regulations prohibiting sale of polyethylene products, while providing consumers with a storage solution that is disposable. Moreover, the biodegradable cooler described herein can include convenient features such as a handle, and the like, and reliably retain water for long durations (e.g., two days).

FIG. 5 shows an exploded view of a biodegradable cooler 500 with a handle according to another embodiment. Referring to FIGS. 1-5, in some example embodiments, the biodegradable cooler 500 includes the outer shell 102, the liner 302, and bottom panel 502. The bottom panel 502 may be placed in the cavity 214 of the outer shell 102 prior to positioning the liner 302 in the cavity 214, and the liner 302 may be positioned on the bottom panel 502. For example, the bottom panel 502 may be positioned on the base 104 of the outer shell 102 to provide added sturdiness to the base 104, for example, when relatively heavier items are placed in the liner 302. To illustrate, the bottom panel 502 may help distribute the weight of the liner 302 and items that are placed in the liner 302, for example, evenly or away from the center of the base 104.

In some example embodiments, the bottom panel 302 may be made from corrugate material, such as recycled corrugate material, or from another biodegradable material. Alternatively, the bottom panel 302 may be made from or may include a material that is not biodegradable. The bottom panel 302 may be sized such that the perimeter of the bottom panel 302 is in contact with the walls of the outer shell 102. In some alternative embodiments, the bottom panel 302 may be sized to be smaller than the base 104.

FIG. 6 shows an outer shell 600 of a biodegradable cooler prior to being expanded to receive a liner according to another example embodiment. FIG. 7 shows a perspective view of a biodegradable cooler 700 that includes the outer shell 600 of FIG. 6 according to another example embodiment. Referring to FIGS. 6 and 7, in some example embodiments, the biodegradable cooler 700 includes the outer shell 600 and a liner, such as the liner 302 of FIGS. 3 A and 3B. In some example embodiments, the biodegradable cooler 700 is similar to the biodegradable cooler 100 of FIG. 1A.

Focusing on the main differences between the outer shell 600 and the outer shell 102, in some example embodiments, the outer shell 600 may include top flaps 708, 710 instead of the roof sections 118, 202 of the outer shell 102 shown in FIG. 4. In some example embodiments, the roof sections, such as a roof section 714, of the outer shell 600 may be substantially flat in contrast to the slanted roof sections 114, 116 of the outer shell 102 of FIG. 1A.

In some example embodiments, the top flaps 708, 710 of the outer shell 600 provide slots, such as a slot 712 formed in the top flap 708, for retaining the outer shell 600 closed.

To illustrate, tabs 704, 706 that extend out from the handle sections of the outer shell 600 may be inserted through the slots, such as a slot 712, to retain the outer shell 600 closed. For example, the tab 704 extends through the slot 712, and the tab 706 extends through the slot in the top flap 708.

In some example embodiments, the outer shell 600 may be made from the same material as the outer shell 102.

FIG. 8 shows a perspective view of a biodegradable cooler according to another example embodiment. In some example embodiments, the biodegradable cooler includes the outer shell 802 and a liner, such as the liner 302 of FIGS. 3 A and 3B. In some example embodiments, the biodegradable cooler 800 is similar to the biodegradable cooler 100 of FIG. 1 A and the biodegradable cooler 100 of FIG. 7.

Similar to the outer shell 102 of FIG. 1 A and in contrast to the outer shell 600 of FIG. 7, roof sections, such as a roof section 806, of the outer shell 802 are slanted. Similar to the outer shell 600 of FIG. 7 and in contrast to the outer shell 102 of FIG. 1 A, the outer shell 802 may include top flaps 808, 810. However, in contrast to the outer shell 600 of FIG. 7 and similar to the outer shell 102 of FIG. 1 A, the top flaps 808, 810 along with the roof sections, such as a roof section 806, may serve to provide a cover to the cavity of the outer shell 802.

In some example embodiments, the top flaps 808, 810 of the outer shell 802 provide slots, such as a slot 814 formed in the top flap 808, for retaining the outer shell 802 closed.

To illustrate, tabs, such as a tab 812, that extend out from the handle sections (e.g., a handle section 804) of the outer shell 802 may be inserted through the slots, such as the slot 814, to retain the outer shell 802 closed. For example, the tab 812 extends through the slot 814.

In some example embodiments, the outer shell 802 may be made from the same material as the outer shell 102. The foregoing description has been directed to certain embodiments of the present disclosure. It will be apparent, however, that other variations and modifications may be made to the described embodiments, with the attainment of some or all of their advantages. Accordingly, this description is to be taken only by way of example and not to otherwise limit the scope of the embodiments herein. Therefore, it is the object of the appended claims to cover all such variations and modifications as come within the true spirit and scope of the embodiments herein.
