BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates generally to the field of insulated containers such as coolers or ice chests. More particularly, the present invention relates to an apparatus and method for providing a cooler having the hard liner integrated with a soft cover.
2. Description of the Related Art
Generally, it is known to provide an insulated container, such as a cooler or an ice chest. Coolers and ice chests may be generally categorized as hardsided or softsided. Hardsided coolers include coolers having an outside body made from hard plastic, such as blow molded or injection molded plastic and thus the hard outside body provides a protective covering for the contents in the cooler. Hardsided coolers may be constructed with a liner within the outside body. Such as liner of the prior art is shown as item 200 in
As stated above, to construct the hardsided coolers, insulating foam may be placed between the liner and the hard outside body to better thermally insulate the cooler. The foam may be poured in liquid form between the outside body and the liner to form the cooler, with the cooler being placed into a curing unit, to cure the foam into a solid stated. A lid may be attached to the cooler via a hinge and a locking mechanism may be provided on the lid to secure the contents stored in the cooler. A rubber seal may be placed around the perimeter of the lid to sealingly engage the perimeter 207 of the liner 200, thereby providing a leak-proof cavity within the cooler.
In contrast to hardside coolers, softside coolers typically comprise coolers made of a pliable material, such as fabric, and may include thermal insulation between the pliable material and the food and/or beverages within the cooler. Softside coolers tend to be popular because softside coolers are often collapsible and require less storage space, when not being used. Softside coolers may be more fashionable than a hardside cooler as a softside cooler may contain pockets, as softside coolers may allow the attachment of accessories or gadgets to the softside material. Softside coolers have advantages of multifunctionality with storage compartments, slip pockets, and other devices, which can easily be sewn to the sides of the softside cooler. However, compared to hardside coolers, softside coolers provide less protection to the contents within the cooler, and may be more prone to wear over time as compared to the hardsided counterparts.
On the other hand, compared to softside coolers, current hardside coolers are known to have improved performance and durability due to the use of plastic liners and lids, compared to coolers made of other materials. As such, hardsided cooler offer improved protection of delicate contents (e.g. sandwiches, eggs, or cake) compared to softsided coolers. Further, cleaning the inside of the plastic liner is also relatively easy compared to cleaning the inside of the softside products. However, hardside coolers may be more difficult to carry and store, as hardside coolers have a hard outer body, which typically is not flexible. Further, it may prove problematic in some instances to attach components or gadgets to the hardside cooler.
Another type of cooler is a combination of a hardsided cooler and a softsided cooler. This hybrid cooler comprises a hard liner 200 of the prior art, typically injection molded, removable from within a softside pouch. The MaxCold™ 10, offered by Igloo Products Corp. of Katy, Tex., is an example of a cooler having a removable hard liner, within a softside (e.g. fabric) outer carrier. The benefits of such a design are that the hard liner is removable for easy cleaning. Further, the softside carrier may also be washed separately. However, the repeated removal of the liner from the cooler may prevent the softside carrier from retaining its original shape; thus, the liner may fall out of the carrier if the cooler is tipped over. Additionally, the soft lid of the softside carrier may not fasten securely as a hardside cooler having a hard lid, in some situations.
In light of the foregoing, it would be desirable to provide an insulated container, such as a cooler or ice chest, which has the advantages of both hardside and softside coolers, while minimizing the disadvantages of hardside and softside coolers. By way of example, it would be desirable that the cooler or ice chest have a durable hard inner surface, which protects the contents of the cooler and is relatively easy to clean. Further, it would be desirable to provide an outer surface of the cooler with a softside material to which accessories may be attached. Additionally, it is desirable to have a hard lid that protects the contents inside and is adapted to securely keep the lid closed. It would also be desirable to be able to attach wheels and an extendable handle to the insulated container or cooler to facilitate transportation of the device.
The present invention is directed to overcoming, or at least reducing the effects of, one or more of the issues set forth above.
SUMMARY OF THE INVENTIONThe insulated container, such as a cooler or ice chest, described herein is an “all-in-one” cooler that combines advantages of both softside and hardside coolers, and creates one solution to some of the disadvantages described above. In some embodiments, the cooler utilizes a hard plastic liner and a plastic lid hingedly attached to the liner, similar to hardsided coolers. Pliable material, such as soft fabric and/or flexible closed-cell foam, may be attached to the hard liner to create the outer walls of the body, in some embodiments. The pliable material may be directly attached to the liner, via glue or via direct stitching, in some embodiments. The fabric and foam may provide thermal advantages, such as keeping heat away from cooled contents or keeping heat from escaping when the cooler contains warm contents.
In another embodiment, the insulated container may utilize a hard container and hard lid. The container and lid may comprise plastic as typically used in hardside coolers and the like. The lid is attachable to the container in such a way to enclose the container in one position and to provide access to the container in another position. A pliable material is attached to the outside of the container to become an integral part of the cooler. The pliable softside material may be nylon, polyester, or other material similar to material typically used in a softside cooler. In yet another embodiment, separate pliable material may be attachable to the lid and may be nylon, polyester, or other material similar to the materials typically used in a softside cooler. It should be understood that the container could be any shape, e.g. cylindrical, square, rectangular, as long as it contains a cavity, as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure.
In some embodiments, an insulated cooler is provided having a hard liner, which contains a cavity, a hard lid hingedly attached to the hard liner, and a softside cover attached to the exterior of the liner. In some embodiments, the pliable material creates a softside cover, and is fastened directly to the exterior of the liner. The pliable material may be fastened to the exterior of the liner by sewing the pliable material to the exterior of the liner; gluing the pliable material to the exterior of the liner; providing velcro straps on the pliable material to fasten through openings in the liner; providing mating snaps on the pliable material and the exterior of the liner; or providing the pliable material and the exterior of the liner with mating parts of a zipper, for example.
In other embodiments, a cooler has a lid is hingedly attached to a liner having a cavity and a softside is also attached to the outside wall of the liner. The cooler may also include a pliable material (or “softside” material) attached to the lid to create a softside cooler. In some embodiments, the softside material may be sewn directly to the liner. In other embodiments, the softside may be snapped or zipped onto the liner. The cooler may further have wheels and an extendable handle attached to the liner. In some embodiments, the softside may contain a side pocket or a front pouch with an accessory such as a carabineer, key ring, or grommet, for example. The front pouch or side pocket may include a portion of mesh material. In one embodiment, the cooler may further have a skid resistant base connected to the bottom of the liner.

Further aspects and advantages of the various embodiments of the invention will become apparent from consideration of the following description and drawings.
As shown in
On the outside of the cooler 100 is shown a pliable (or softside) material 240. The pliable material of the cooler of this embodiment may comprise fabric, flexible polyester, and closed-cell foam, for example. Between the liner 200 and the pliable material may be placed insulating material. The pliable material 240, such as closed-cell foam, shown on the outside of the cooler 100, may be attached directly to the hard plastic of the liner 200 to create the outer walls of the body in this embodiment. For example, the pliable material 240, such as closed-cell foam, may be directly attached to the liner 200, via glue or adhesive placed there between. Alternatively, the pliable material may be directly stitched to the liner 200. The closed-cell foam provides insulation for the liner 200. Furthermore, closed-cell foam is adapted not to absorb liquid if either the liner 200 or pliable material 240 were to leak or tear.

To construct the insulated container 100, the pliable or softside material 240 is attachable to the liner 200 in various ways. For instance, the pliable softside material 240 may be directly affixed to the outside of the liner 200 via adhesive or glue. Or the pliable softside material 240 may be directly stitched to the liner 200, as described above. In the embodiment of
Further, the pliable material 240 may include a ring or hoop of hardened material (e.g. plastic) attached to the upper end of the material 240 and located on the upper perimeter of the bag-shaped pliable material for assembly purposes. The upper end of the pliable material 240 may be stitched around the hoop or ring.
To construct the insulated container 100 of
Further, the lid 220 of the cooler 100 may contain a softside material 240 attached to the lid 220. For example, the softside material 240 may be directly attached to the lid, such as being glued or sewn onto the lid.
In the embodiment shown in
The outside cover of softside material 240 may also include a side slip pocket 95. In the embodiment of
As shown in
In the embodiments of
The lid 220 rests against the upper perimeter of the liner 200 when the lid is closed. The upper perimeter of the liner 200 of the insulated container 100 may include a recess 201, as shown in
In the embodiment of
As stated above, the handle 10 of the insulated container 100 may be comprised of single “T” member 10 as shown in
Referring to
Accessory holders may be provided on the insulated container 100. For example, as shown in
It should be noted that heretofore, the attachment of the softside pliable material 240 to the hardside liner 200 proved problematic; however, with improvements in manufacturing and sewing technology as described above, the softside exterior may be directly attached to the hardside interior. For example, one means for attaching the softside material 240 to the hard liner 200 is sewing the softside material 240 directly onto the hardside liner 200. Another means for attaching the softside material 240 to the liner 200 is via glue. Yet another means for attaching the softside material 240 to the liner 200 is by incorporating mating snaps on both the softside material 240 and the hard liner 200 such. Yet another means for attaching the softside material 240 to the liner 200 is velcro straps on the softside material or hook and loop straps on the softside material that feed through an opening in the liner 200 or fasten around an exterior element of the liner 200. While, yet another means for attachment could be to provide the softside material 240 and hardside liner 200 with mating parts of a zipper and zipping the softside material around the outside of the hardside liner. In short, other means for attaching the softside material may be utilized. A preferred method of attaching the pliable material 240 to the liner 200 is via the hoop on the upper perimeter of the pliable material 240 being snapped into the circumferential pocket formed between the lip 208 and the upper perimeter of the liner 200 as described above. In this way, the insulated container 100 has benefits of softside coolers (e.g. the cooler 100 can contain pockets 95 and pouches 40 and is fashionable) and also has the benefits of a hardside cooler (such as offering the protection of the contents in the container and allowing for the rigid attachment of hardware such as wheels 20, feet 300, and extendable handle 10).
As described above with respect to
In the embodiment of
Also the lid 220 can be opened more quickly than when other securing means are utilized, such as prior art zippers. Further, the stress induced on the upper perimeter of the liner 200 is relatively low and affects only a percentage of the perimeter of the upper end of the liner 200. That is, the entire upper end of the liner 200 is not stress-cycled as the lid 220 is opened and closed, as would be the case if the lid 220 had a perimeter just slightly larger than the upper perimeter of the liner 220 creating an interference fit all the way around the parameter.
Thus, with the reduced stress, durability of the container is increased concomitantly. The resulting stress is applied only to a small area as compared to other applications to secure the lid 220 and liner 200 such as creating seal ring around entire perimeter of the liner 200. Additionally, this embodiment does not cause excessive wear upon the opening and closing mechanism or on the mechanism the operator would grasp to open the lid, e.g. the softside pliable material.
The lid 220 may also include other types of mechanisms for securing the lid 220 in a closed position with respect to the liner 200, as would be realized by one of ordinary skill in the art having the benefit of this disclosure. For example, the lid 220 may contain an inner surface that snaps onto a lip on the inside of liner 200 when the lid 220 is closed onto the liner 200.
