A drawback to many conventional coolers is that such coolers generally require a large amount of storage space when not used. Such coolers are typically stored in a garage, storage shed or closet when not in use because of their size. Further, such coolers take up relatively large amounts of space whenever they are transported for use. This is particularly disadvantageous when the coolers are packed into the family car when going on the family vacation at the beach. Because they are so large and bulky, they tend to consume a large portion of the available space in the car, thereby limiting the other items that can be taken on the vacation. In addition to being disadvantageous for consumers, such devices also are less desirable to retailers, who have limited shelf space on which to display goods for sale.
Collapsible insulated containers also are known which may be utilized for storage of perishable items and that have a storage configuration that is smaller in volume than their use configuration. Such known devices are disclosed, for example, in U.S. Pat. Nos. 3,347,060; 4,085,785; 4,091,852; 4,612,781; and 7,387,305, as well as in U.S. Pat. Appl. Publ. No. 2007/0023439 A1, each of which is hereby incorporated herein by reference. While these collapsible coolers are believed to be adequate to meet the intended purposes of their use, it is believed that a need continues to exist for an improved collapsible cooler, and that such need is met by one or more of the embodiments of the present invention.

Further aspects, features, embodiments, and advantages of the present invention will become apparent from the following detailed description with reference to the drawings, wherein various embodiments of cooler within the scope of the present invention are disclosed and described with reference to
As a preliminary matter, it will readily be understood by one having ordinary skill in the relevant art (“Ordinary Artisan”) that the present invention has broad utility and application. Furthermore, any embodiment discussed and identified as being “preferred” is considered to be part of a best mode contemplated for carrying out the present invention. Other embodiments also may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the present invention and may or may not be a preferred embodiment. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention.
Accordingly, while the present invention is described herein in detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the present invention, and is made merely for the purposes of providing a full and enabling disclosure of the present invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed, to limit the scope of patent protection afforded the present invention, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.
Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the present invention. Accordingly, it is intended that the scope of patent protection afforded the present invention is to be defined by the appended claims rather than the description set forth herein.
Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein—as understood by the Ordinary Artisan based on the contextual use of such term—differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should prevail.
Furthermore, it is important to note that, as used herein, and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single apple” describes “a picnic basket having only one apple.”
When used herein to join a list of items, “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers” describes “a picnic basket having cheese without crackers”, “a picnic basket having crackers without cheese”, and “a picnic basket having both cheese and crackers.” Finally, when used herein to join a list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has cheese.”
Referring now to the drawings, in which like numerals represent like components throughout the several views, preferred embodiments of the present invention are next described. The following description of preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
The base 20 includes two pairs of coaxial wheels 22, a bottom 24, and a top surface 26. The two pairs of coaxial wheels 22 are each connected to the base 20 with a conventional wheel axle. The wheels 22 facilitate rolling motion of the cooler 10 from one location to another and are preferably constructed of a material capable of supporting the weight of the items stored in and on the cooler 10. It is preferred that the wheels 22 be able to support at least about ninety pounds. It is more preferred that the wheels 22 be able to support at least about one hundred and ten pounds.
The base 20 has a generally rectangular perimeter. Additionally, the base 20 is tapered such that the top surface 26 has a greater perimeter than the bottom 24. In a variation, however, the base is not tapered and, instead, includes generally orthogonal side and lateral surfaces.
Preferably, a handle 28 is attached to the base 20 at a hinge such that it can be raised and lowered about the hinge. The handle 28 includes an elongate shaft portion 27 having a handle portion 29 affixed to its end, as can be seen in
The cooler wall 50 is attached to the top surface 26 of the base 20. The cooler wall 50 includes a collapsible inner wall 52 and a collapsible outer wall 54. Preferably, one or both collapsible walls 52,54 are bonded, adhered, or cold-molded to the base 20. Each collapsible wall 52,54 comprises a flexible, elastomeric membrane 60. In at least one embodiment, one or more collapsible walls consists of a flexible, elastomeric membrane and nothing further that would impede the collapsibility and nesting of sections of the walls.
The membrane 60 includes a plurality of hinge lines 62, as can be seen in
Each hinge line 62 is defined between an upper hinge face 63 and a lower hinge face 64. The membrane 60 is configured to be bent at each hinge line 62 such that the associated upper hinge face 63 is bent downwards generally towards the associated lower hinge face 64. By bending a membrane 60 thusly, the membrane 60 can be transitioned to a collapsed yet stable state having a reduced height.
The membrane 60 has both an inner surface 68 and an outer surface 69. Preferably, if a membrane 60 has a plurality of hinge lines 62, then the membrane is configured such that a first hinge line 62 has hinge faces 63,64 associated therewith that are part of the outer surface 69 and the second hinge line 62 has hinge faces 63,64 associated therewith that are part of the inner surface 68. In this way, although each hinge line 62 is defined in both the inner and outer surfaces 68,69, the surface 68,69 which comprises the associated hinge faces 63,64 alternates.
It will be understood that when such a membrane 60 is folded at a hinge line 62 (labeled as 65 in
It also will be understood that a membrane 60 having a plurality of hinge lines 62 and associated hinge faces 63,64 has a fully collapsed configuration, wherein it is collapsed at each hinge line 62; a fully expanded configuration, wherein it is not collapsed at any hinge lines 62; and a plurality of partially collapsed configurations, wherein it is collapsed at least one hinge line 62 but not at least one other hinge line 62. Preferably, when the membrane 60 is in the fully collapsed configuration, it can be characterized as having a plurality of concentric portions all disposed generally in the same plane. Additionally, the membrane 60 is preferably configured to be stable not only in the fully collapsed and fully expanded configurations, but in the plurality of partially collapsed configurations as well.
In addition to having hinge lines 62, a membrane can also include one or more stiffening portions. An example of a membrane having such stiffening portions is disclosed in U.S. Patent Application Publication No. 2006/0096929, which publication is hereby incorporated herein by reference. In this publication the stiffening portions are characterized as “stiffening rings”, but it will be appreciated that these stiffening rings could be implemented as “stiffening portions” in one or more preferred embodiments in accordance with the present invention. Further, the membranes themselves as detailed therein could be utilized or implemented, either with or without changes or modifications, in one or more preferred embodiments in accordance with the present invention.
Similarly, the membranes detailed in U.S. Patent Application Publication No. 2007/0251874, which publication is also hereby incorporated herein by reference, could be utilized or implemented, either with or without changes or modifications, in one or more preferred embodiments in accordance with the present invention.
Preferably, a membrane is formed of silicone rubber, such as, for example, silicone rubber having a softness of about 25 on the Shore A scale.
Returning to the cooler 10 of
The top portion 66 of the membrane of both the inner collapsible wall 52 and the outer collapsible wall 54 is attached to the upper rim 30. The upper rim 30 includes a rigid inner rim wall 32 and a rigid outer rim wall 34, as illustrated in
The upper rim 30 includes a plurality of connectors 33 that secure the inner rim wall 32 and the outer rim wall 34 to one another in a spaced apart relationship (i.e., the inner rim wall and the outer rim wall are preferably spaced apart), as can be seen in
A lid 40 is attached to a first side of the upper rim 30, and more specifically to the outer rim wall 34, by hinges 42. The lid 40 can be lowered about the hinges 42 into a closed position in which it fully covers both the inner opening 38 and the peripheral opening 39, thereby sealing both the interior space 12 and the intermediate space 14, as illustrated in
The lid 40 includes a male fastening insert 46 configured to mate with a female fastening slot 44, located on a second side opposite the first side, such that the lid 40 is retained in a closed position.
It will be understood that because the collapsible walls 52,54 each comprise a membrane, such as, for example, membrane 60 described hereinabove, each of the walls 52,54 can be transitioned between a fully expanded configuration, a fully collapsed configuration, and a plurality of partially collapsed configurations. Further, because both of the collapsible walls 52,54 are attached to the upper rim 30, the collapsible walls 52,54 generally collapse and expand together. Thus, by transitioning the collapsible walls 52,54 from one configuration to another, the cooler 10 itself is transitioned between a fully expanded configuration, which can be seen in each
It will be understood from the above description that the cooler 10 has a plurality of configurations that may be utilized. Various examples utilizing these configurations will now be described, although it will be appreciated that many other uses that are not described do exist and also lie within the scope of the present invention.
A user wishing to keep items cooled or chilled utilizes the cooler 10 in either the fully expanded configuration, or one of the partially collapsed configurations. It will be understood that the interior space 12 will be larger, and thus the volume of items that can be stored will be greater, when the cooler is in the fully expanded configuration.
To store items in the cooler 10, a user first disengages the male fastening insert 46 from the female fastening slot 44. The user then lifts the lid 40, thereby exposing the inner opening 38 and the peripheral opening 39. The user inserts ice through the peripheral opening 39 into the intermediate space 14 of the cooler wall 50, and places the items to be chilled or otherwise kept cool within the interior insulated space 12 of the cooler 50. The ice in the intermediate space 14, which is separated by the collapsible inner wall 52, surrounds the interior space 12 and chills the interior space 12. The lid 40 can be lowered and the male fastening insert 46 engaged with the female fastening slot 44, thus retaining the lid in the closed position.
The handle 28 can be grasped and the cooler 10 rolled from its current location to another location, where the cooler can be opened to provide access to the chilled items. The handle 28 also is pivotably connected to the base by a hinge 31 (shown in dashed lines in
A variation of the cooler 10 is illustrated in
The bracket members serve to convey tensional forces between the base and the upper rim 30 if and when the cooler is lifted by the upper rim 30. The bracket members 30 are preferably included in the cooler 10 if the cooler is not otherwise constructed so as to be able to withstand the tensional forces in the collapsible wall 50 when the fully loaded cooler is in the fully expanded configuration and is lifted from the upper rim 30, as opposed to lifted from the base 20.
A plurality of additional preferred embodiments are now described hereinbelow.
A cooler 110 in accordance with a second preferred embodiment is now described with reference to
In particular, rather than having collapsible inner and outer walls 52,54 both attached to a top surface 26 of a base 20, the cooler 110 has only a collapsible outer wall 154 attached to a top surface 126 of a base 120. Rather than being so attached, a collapsible inner wall 152 instead extends upward from a bottom wall 151, which is integrally formed with the collapsible inner wall 152.
It will be understood that, in the cooler 110, the intermediate space 114 includes not only the space defined between the collapsible inner and outer walls 152,154 but additionally includes the space defined between the bottom wall 153 and a top surface 126 of a base 120. Consequently, ice placed within the intermediate space 114 will cool the insulated space not only from the sides thereof, but also from the bottom thereof.
It will further be understood that, because the collapsible walls 152,154 are not coupled or otherwise joined to one another at bottom portions 167 of their respective membranes 160, the respective expanding and collapsing of the walls 152,154 are not necessarily dependent upon one another. More specifically, the cooler 110 is capable of transitioning to a configuration wherein the collapsible inner wall 152 is collapsed to an extent that is equal to or greater than the collapsed extent of the outer wall 154 (i.e., it is collapsed to a greater extent), thus increasing or decreasing a volume of space defined between the bottom wall 151 and the top surface 126 of the base 120.
A cooler 210 in accordance with a third preferred embodiment is now described with reference to
In particular, rather than having a peripheral opening defined between inner and outer rim walls 32,34, the cooler 210 includes an upper rim having a closed top surface 235, as can be seen in
A cooler 310 in accordance with a fourth preferred embodiment is now described with reference to
In particular, the cooler 310 includes one or more drain conduits 372, as illustrated in
Furthermore, in another variation of this embodiment of the invention, a cooler includes both a first drain conduit in fluid communication with the intermediate space, and a second drain conduit in fluid communication with the interior space. Each drain conduit may be located on the exterior of the cooler either along a side or along a bottom of the cooler, and preferably includes a plug or a valve or spigot for selectively opening and closing the drain conduit and thereby control flow of liquid through the drain conduit.
In at least one preferred variation of this embodiment of the invention, a cooler is a water cooler adapted to receive and retain water or other liquid therein for dispensing via a spigot comprising a drain conduit. Preferably, the water cooler has a generally circular perimeter and is configured to hold between approximately five gallons and approximately ten gallons.
A cooler 410 in accordance with a fifth preferred embodiment is now described with reference to
In particular, the cooler 410 includes at least one gripping handle 436 comprising portions of an upper rim 430 which extend outward on opposite lateral sides of the upper rim 430, beyond a lid 440, when the lid 440 is in a closed position. Each gripping handle 436 is defined by a generally rectangular or trapezoidal aperture 431 in the upper rim 430, as can be seen in
The cooler 410 is shown having a single gripping handle 436 in
Two coolers 510a,510b in accordance with a sixth preferred embodiment are now described with reference to
In particular, rather than including two pairs of coaxial wheels 22, a base 520a,520b of the respective coolers 510a,510b includes only a single pair of coaxial wheels 522a,522b, as can be seen in
A cooler 610 in accordance with a seventh preferred embodiment is now described with reference to
A cooler 710 in accordance with an eighth preferred embodiment is now described with reference to
In particular, the cooler 10 generally tapers from its top to its bottom, in that the membrane of each collapsible wall 52,54 is tapered such that its top portion has a greater perimeter than its bottom portion; the base 20 is tapered such that its top surface 26 has a greater perimeter than its bottom 24; and the upper rim 30 is tapered such that a top portion of each rim wall 32,34 has a greater perimeter than a bottom portion of each rim wall 32,34. It will thus be appreciated that the upper rim 30 has a substantially greater perimeter than the base 20.
In contrast, the cooler 710 tapers from its bottom to its top. For example, in
A cooler 810 in accordance with a ninth preferred embodiment is now described with reference to
In particular, rather than tapering simply from its top to its bottom or from its bottom to its top, the cooler 810 instead tapers from both its top and its bottom towards a middle of the cooler 810, as can be seen in
A cooler 910 in accordance with an tenth preferred embodiment is now described with reference to
In particular, rather than having a generally rectangular perimeter, the cooler 910 has a base 920, an upper rim 930, inner collapsible wall (not shown), and outer collapsible wall 954. The inner and outer collapsible walls each have a generally elliptical perimeter and, in particular, a generally circular perimeter, as illustrated in
The cooler 910 further may include one or more drain conduits in fluid communication with the intermediate space between the inner and outer walls and/or in fluid communication with the insulated interior space of the cooler 910.
In another variation of the cooler 910 depicted in
A cooler 1110 in accordance with an eleventh preferred embodiment is now described with reference to
In particular, rather than having a handle 28 attached to a base 20, the cooler 1110 has a handle 1128 attached to an upper rim thereof at opposite sides of the upper rim 1130, as illustrated in
Alternatively, the handle is fixedly attached to the upper rim such that the handle is not movable relative to the upper rim of the cooler.
A cooler 1210 in accordance with an twelfth preferred embodiment is now described with reference to
In particular, the cooler 1210 is configured such that its upper rim 1230 engages with and locks into its base 1220 when the cooler 1210 is in a collapsed configuration. Preferably, the upper rim 1230 includes a snap fastener 1237 adapted to mate with a snap fastener 1225 of the base 1220, as can be seen in
A cooler 1310 in accordance with a thirteenth preferred embodiment is now described with reference to
In particular, the cooler 1310 is configured such that its outer collapsible wall 1354 is generally unexposed and thereby protected when the cooler 1310 is in a fully collapsed configuration, as shown in
A cooler 1410 in accordance with a fourteenth preferred embodiment is now described with reference to
In particular, the cooler 1410, rather than having a generally rectangular perimeter, has a perimeter with a generally arcuate portion and a generally linear portion, as illustrated in
A cooler 1510 in accordance with another preferred embodiment is now described with reference to
In particular, rather than having collapsible inner and outer walls 52,54 both attached to a top surface 26 of a base 20, the cooler 1510 has a collapsible inner wall 1552 extending upward from an inner bottom wall 1551, which is integrally formed with the collapsible inner wall 1552; and a collapsible outer wall 1554 extending upward from an outer bottom wall 1553, which is integrally formed with the collapsible outer wall 1554.
It will be understood that in the cooler 1510, the intermediate space 1514 defined between the inner and outer walls 1552,1554 includes not only the space defined between the collapsible inner and outer walls 1552,1554 but additionally includes the space defined between the inner bottom wall 1551 and the outer bottom wall 1553.
It will further be appreciated that, because the collapsible walls 1552,1554 are not coupled to one another in any fashion at bottom portions of their respective membranes, the collapsible walls 1552,1554 can be independently collapsed or expanded. More specifically, the cooler 1510 is capable of transitioning to a configuration wherein the collapsible inner wall 1552 is collapsed to the same or to a greater extent than the collapsible outer wall 1554 (e.g., to a first expanded state with the outer wall in a second expanded state), thus increasing the volume of space defined between the inner bottom wall 1551 and the outer bottom wall 1553.
A cooler 1610 in accordance with another preferred embodiment is now described with reference to
In another preferred embodiment, a cooler 1710 is similar to the cooler 1610, except the cooler 1710 does not include an upper rim. Additionally, in a variation of cooler 1710, connectors or spokes are provide that extend between and join together the inner and outer collapsible walls of the cooler. Preferably, the connectors are rigid or semirigid and can be integrally formed (such as in a co-molding manufacturing process) with the inner collapsible wall and/or the outer collapsible. Additionally, the cooler 1710 and such variation may include a single bottom wall integral with both the inner and outer bottom walls, in the manner as cooler 1510.
In another preferred embodiment, rather than including collapsible inner and outer walls 52,54, a cooler includes only a single collapsible wall. Such a cooler preferably includes a base and an upper rim, but in alternative embodiments lacks one or both of these features.
A cooler 1908 in accordance with another preferred embodiment is now described with reference to
In variations of some of the foregoing embodiments in which the cooler includes a wheeled platform (such as wheeled platform 1990 of cooler 1908), the portion of the cooler defining the interior insulated space (including the lid and collapsible wall) may include a base and may be removably coupled to the wheeled platform and can be coupled and uncoupled therefrom. Such wheeled platform is preferably durable and rigid and is formed in one or more molding processes. Moreover, as used herein, “molding” may include injection molding, rotational molding, and/or blow molding. Furthermore, the wheeled platform may be integrally formed as a single piece or may be separately formed as multiple pieces and, thereafter, connected or joined together.
The cooler portion may be coupled to the wheeled platform by coupling components. When the cooler is coupled to the wheeled platform, the coupling components preferably are disposed in interlocking engagement with one another, whereby the cooler is securely coupled to the wheeled platform for safe transportation on the wheeled platform, i.e., the cooler is protected from falling off of the wheeled platform during transport over rough terrain such as grass or a sand dune. The coupling components may comprise snap components and/or hook and loop fastening components.
Portable coolers that may be removably coupled to a wheeled platform are further described in, for example, Vanderberg U.S. Pat. No. 7,387,305, which is incorporated herein by reference.
Additional features that may be incorporated into coolers of the present invention and that fall within the scope of the present invention are disclosed in the incorporated Vanderberg references. Such incorporated feature may be utilized together in combination with the aspects and/or one or more features disclosed herein.
Based on the foregoing description, it will be readily understood by those persons skilled in the art that the present invention is susceptible of broad utility and application. Many embodiments and adaptations of the present invention other than those specifically described herein, as well as many variations, modifications, and equivalent arrangements, will be apparent from or reasonably suggested by the present invention and the foregoing descriptions thereof, without departing from the substance or scope of the present invention.
Accordingly, while the present invention has been described herein in detail in relation to one or more preferred embodiments, it is to be understood that this disclosure is only illustrative and exemplary of the present invention and is made merely for the purpose of providing a full and enabling disclosure of the invention. The foregoing disclosure is not intended to be construed to limit the present invention or otherwise exclude any such other embodiments, adaptations, variations, modifications or equivalent arrangements.
