Insulated containers, sometimes called “coolers” are quite popular, and are used in numerous activities. Large coolers are often seen at picnics and other social gatherings, and individual users utilize smaller coolers, such as to transport soup to work or to maintain a beverage at a cooler temperature during a sporting activity.
Typically, the walls of contemporary coolers include hard outer and inner shells, and an insulating central layer. The central layer is usually a product having a high insulation value, or R value, such as expanded polystyrene or polyurethane.
For most contemporary coolers, the outer and inner layers of the insulated containers are each formed in separate vacuum, injection, or blow molding machines. Liquid polyurethane is then manually placed between the inner and outer layers, and is permitted to expand to fill the void between the two layers. Alternatively, molded polystyrene foam is manually placed in the void between the two layers. The result is a container having smooth, hard, outer and inner surfaces, and an insulating central core. The outer layer protects the container and central core, and provides an attractive surface. The inner layer separates the central core from the contents of the container, and provides an impermeable layer so that liquids may be stored in the container.
Other insulated containers may be made to have soft sides. For example, soft-sided coolers may be formed from an insulating material, such as high density polyurethane foam, that is surrounded by a flexible fabric, such as vinyl. Such coolers may be produced by covering one or more pieces of insulating material with a flexible material and stitching the pieces or portions of the pieces together so as to form a container.
The following presents a simplified summary of some embodiments of the invention in order to provide a basic understanding of the invention. This summary is not an extensive overview of the invention. It is not intended to identify key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some embodiments of the invention in a simplified form as a prelude to the more detailed description of some embodiments that are presented later.
In accordance with an embodiment, a cooler is provided that is configurable between an open configuration and a storage configuration. The cooler includes two containers attached to one another along an edge. The cooler may be put into a storage configuration by folding together both containers along the edge so that the two containers are aligned against one another. A zipper or other fastener may secure the cooler in the storage configuration. The fastener is released and the two containers are moved apart in the open configuration.
In accordance with another embodiment, a cooler is provided including a bag having a zipper with teeth lining opposite upper edges of opposite sides. The cooler is configurable between an open configuration and a closed configuration by folding the upper edges towards each other, closing the zipper, and folding the ends of the edges downward.
In accordance with yet another embodiment, a soft-sided cooler is provided having a handle located in a corner of the cooler. The cooler may include two containers attached to one another along an edge. The cooler may be put into a storage configuration by folding together both containers along the edge. A zipper or other fastener may secure the cooler in the storage configuration.
In accordance with yet another embodiment, a soft-sided cooler is provided having a drink holder located on a substantially vertical surface. The drink holder includes a flap having a bottom edge attached horizontally to the substantially vertical outer surface and is configurable between an open configuration (wherein the flap is positioned substantially below the bottom edge) and a closed configuration (wherein the flap is positioned substantially below the bottom edge) by rotating the flap about the bottom edge. A pocket attached to the flap and having an opening providing access to an interior of the pocket may be positioned between the flap and the substantially vertical outer surface when the flap is in the closed configuration. A fastener may releasably connect the flap to the substantially vertical outer surface when the flap is in the closed configuration.
Other features of the invention will become apparent from the following detailed description when taken in conjunction with the drawings, in which:
In the following description, various embodiments of the present invention will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will also be apparent to one skilled in the art that the present invention may be practiced without the specific details. Furthermore, well-known features may be omitted or simplified in order not to obscure the embodiment being described.
Referring now to the drawings, in which like reference numerals represent like parts throughout the several views,
The top panel 20, bottom panel 22, back panel 24 are connected together along their edges to form a box-like shape. In particular, the top panel 20 may have an elongated rectangular shape and may be connected along an edge 23 to three consecutive edges of the back panel 24. The lid 26 is configured to have substantially the same shape of the flap 16 and is connected along an edge to the edge 18. A water-tight zipper (not shown, but known in the art) may extend around the lid 26 at places where the lid 26 meets the first container 12 in order to seal the interior of the first container 12.

In the closed configuration, as shown in
To put the cooler 10 into the open configuration from the closed configuration, the slide 46 is simply grasped and moved along the full length of the zipper 40 in a direction opposite to that described above. Moving the slide 46 in this direction causes the teeth of both the first set of teeth 42 and the second set of teeth 44 to disengage. With substantially all of the teeth of the first set of teeth 42 and second set of teeth 44 disengaged, the first container 12 and second container 14 are rotated about the edge 18 away from the flap 16 until the cooler 10 is in the open configuration, as shown in
The tub 114 may be a layer of fabric, such as polyester, surrounding at least a portion of the bottom 126, and contributing to the strength and durability of the bottom 26. The handles 116 may be elongated strips of material, such as polyester, one handle being attached at both ends to the front 122 and one handle being attached at both ends to the back 124.
Each side 120 may include magnetic snaps 134, including two first magnetic disks 136 and two second magnetic disks 138, although other fasteners, such as snaps, may be used. As shown in
The zipper 128 is similar to the zipper 40 described above and includes a first set of teeth 154 and a second set of teeth 156. The second set of teeth 156 includes a slide 157, similar to the slide 46 described above. As shown in
With the zipper 128 closed, the portions of the sides 120 above the creases 142 and 144 are folded over the creases 142, 144 to form flaps 164. The flaps 164 are folded downward until the first magnetic disks 136 engage the second magnetic disks 138. Magnetic forces secure the first magnetic disks 136 to the second magnetic disks 138 and, therefore, secure the flaps 164 against the sides 120, as shown in
The steps for putting the cooler 110 into a closed configuration are followed in reverse in order to put the cooler 110 into an open configuration, as shown in
As shown in
The handle 228 may also be rigid. For example, the handle 228 may be a loop of stainless steel. A rigid handle 228 may penetrate the first container 212 and the second container 214 in order to connect to the cooler 210. The first container 212 and second container 214 may be able to move relative to the handle 228 so that the first container 212 and second container may freely rotate about the edge 218, as described above.
Locating the handle 228 in near the edge 218 allows the cooler 210 to have a single handle 228 located in a convenient location that does not interfere with changing the cooler 210 between an open configuration and a closed configuration. In addition, positioning the handle at the corner allows convenient, secure carrying of the cooler 210.

When in the open configuration, items such as a bottle 332 may be held in the drink holder 316. Specifically, the bottom of the bottle 332 may be inserted past the elastic strip 330 into the pocket formed by the netting 328. The elastic strip 330 exerts force on the bottle 332, preferably at a narrowing of the bottle 332, thereby holding the bottle 332 in the drink holder. The bottle may be removed by gripping the neck of the bottle 332 and pulling upwards with enough force to overcome the force of the elastic strip 330 holding the bottle 332 in the drink holder.
To put the drink holder 316 into the closed configuration from the open configuration, the flap 18 is folded upward about its bottom edge 320 until the first and second set of teeth 322, 324 are aligned. The netting 328 is positioned between the flap 318 and the outer vertical surface of the tub 312 so that the zipper slide 328 may be moved from one end of the first and second set of teeth 322, 324 in the opposite direction as that described above. Moving the zipper slide 326 in this manner causes the first set of teeth 322 to mesh with the second set of teeth 324 so as to hold the drink holder 316 in the closed configuration.
Variations of the drink holder 316 are also possible. For example, the flap 318 could be formed from an elongated strip of flexible material folded in half, with an upper half of the elongated strip attached to the outer vertical surface of the tub 312 and the other half unattached so as to form a flap similar to the flap 318. The elongated strip may include a mechanism, such as a leaf spring, for biasing the flap in the open or closed configurations. Part of the flap 318 may be formed from material of the tub 312. In addition, other fasteners such as hook-and-loop fasteners or snaps may be used instead of or in addition to a zipper.
All of the coolers 10, 110, 210, 310 may have additional features, many of which may be common to coolers. For example, any of the coolers 10, 110, 210, 310 may include additional features, such as pockets. As another example, while the above description refers to soft-sided coolers, the above coolers may be made to have hard sides. Also, features of one of the coolers 10, 110, 210, 310 may be used with the others. Fasteners other than zippers may also be used with any of the coolers 10, 110, 210, 310. For instance, a hook and loop fastener may be used instead of a zipper. Moreover, any of the coolers 10, 110, 210, 310 may include more than one zipper or other fasteners. The drink holder 316 may also be configured with different sizes to hold other items such as electronic devices, bottles of various sizes, food items, flashlights, or any item commonly used with coolers. Moreover, the drink holder 316 may be incorporated into other coolers, such as the coolers 10, 110, 210, and any cooler may have more than one drink holder, perhaps of varying sizes.
