Abstract

An insulated cooler that can be collapsed is disclosed. The cooler has a securing mechanism that allows a user to maintain the cooler in collapsed state indefinitely as well as reversibly convert the cooler from a collapsed state for storage to an expanded state for use. The securing mechanism may also allow a user to secure an item, such as a towel, to the exterior of the cooler while in the expanded state. The cooler can have a bottom, one or more sides, and a top. The shape of the coolers can be determined by selecting an appropriate number of side faces. The exterior of the cooler may have pockets, handles, or adjustable straps to increase the usefulness of the cooler. The securing mechanism may also be used to selectively secure an object or item onto the cooler when the cooler is in an expanded state.

Claims

1. A cooler comprising:

four sides comprised of soft side material to form a rectangle;

a top comprising soft side material attachable to each of the sides;

a bottom comprising soft side material attachable to each of the side, wherein the cooler has an expanded state and a compressed state; and

an elastic strap attachable to the top, wherein the elastic strap or shock cord retains the cooler in the compressed state.

2. The cooler of claim 1, wherein the elastic strap is adapted t secure an item to the top of the cooler while the cooler in the expanded state.

3. The cooler of claim 1, wherein the cooler further comprises an interior ice pack pocket.

4. The cooler of claim 1, wherein the cooler further comprises a heat sealed liner.

5. A cooler comprising:

a bottom;

at least one side;

a top, wherein at least one of the bottom, at least one side, or top comprises a substantially pliable material, such that the cooler is adapted to be collapsed from an expanded state; and

means for retaining the cooler in a collapsed state.

6. The cooler of claim 5, wherein the means for retaining the cooler in a collapsed state is an elastic band.

7. The cooler of claim 5, wherein the means for retaining the cooler in a collapsed state is an elastic shock cord.

8. The cooler of claim 5, wherein the means for retaining the cooler in a collapsed state is a strap in combination with snaps.

9. The cooler of claim 5, wherein the means for retaining the cooler in a collapsed state is adapted to secure an item to an exterior of the cooler when the cooler is in an expanded state.

10. The cooler of claim 5, wherein the top is reversibly attachable to the at least one side.

11. The cooler of claim 10, wherein the top is reversibly attachable to the at least one side with a zipper or elastic fitting.

12. The cooler of claim 5, wherein the bottom, at least one side, and top define a waterproof cavity.

13. The cooler of claim 12, wherein the cooler further comprises at least one internal partition or internal pocket.

14. The cooler of claim 5, wherein at least one of the top, at least one side, or bottom comprises an insulated material.

15. The cooler of claim 5, wherein the cooler further comprises at least one handle, shoulder strap, or external pocket.

16. The cooler of claim 5, wherein at least one of the top or bottom comprises a substantially rigid material.

17. The cooler of claim 5, wherein at least one of the top, at least one side, or bottom comprises at least one of polyvinylchloride, nylon, fabric, or foam.

18. The cooler of claim 5, wherein the top, at least one side, and bottom define a cylindrical cavity.

19. The cooler of claim 5, in which the means for retaining the cooler in the collapsed state is also adapted t secure an item to the top of the cooler while the cooler in the expanded state.

20. The cooler of claim 19 in which the means for retaining the cooler in the collapsed state is an elastic strap.
