Abstract

A thermal wrap includes a fabric band having a thermally insulating outer layer and a non-insulating inner layer. A cavity is formed between the two layers for receiving a flexible cold pack containing deionized water and a chemical freezing agent. In one embodiment, the fabric band is in the form of a collar to be worn about the individual'"'"'s neck or other body part. In another embodiment, the fabric band is in the form of a jacket for surrounding a beverage container such as a wine bottle.

Claims

1. A thermal wrap comprising:

(a)

a flexible band having

an outer layer formed of thermal insulating material,

an inner layer formed of non-insulating material,

a pair of opposite ends,

a pair of opposite edges extending longitudinally between said opposite ends,

fastening means for securing said opposite ends to one another to form an annulus, and

a cavity formed between said inner layer and said outer layer; and

(b) a flexible cold pack carried within said cavity, said cold pack containing deionized water and a chemical freezing agent.

2. The thermal wrap according to claim 1, wherein said cold pack comprises a plurality of individually sealed compartments containing said deionized water and said chemical freezing agent.

3. The thermal wrap according to claim 1, wherein said fastening means comprises cooperating elements of a demountable fastener for detachably securing said opposite ends to one another.

4. The thermal wrap according to claim 3, wherein said cooperating elements comprise adjustment means for varying the size of said annulus.

5. The thermal wrap according to claim 1, wherein said fastening means comprises stitching for permanently securing said opposite ends to one another.

6. The thermal wrap according to claim 1, further comprising an opening formed in one of said ends and communicating with said recess to allow easy insertion and removal of said cold pack.

7. The thermal wrap according to claim 6, further comprising longitudinal slit means communicating with said opening and said recess for facilitating insertion and removal of said cold pack.

8. A thermal collar to be worn by an individual for cooling purposes, said collar comprising:

(a)

a flexible band for encircling a portion of said individual'"'"'s body, said band including

an outer layer for facing away from said individual'"'"'s body,

an inner layer for contacting said individual'"'"'s skin,

a pair of opposite ends,

a pair of opposite edges extending longitudinally between said opposite ends,

first fastening means for detachably securing said opposite ends to one another to form an annulus around said part of said individual'"'"'s body, and

a cavity formed between said inner layer and said outer layer; and

(b) a flexible cold pack carried within said cavity.

9. The thermal collar according to claim 8, wherein said first fastening means comprises adjustment means for varying the size of said annulus.

10. The thermal collar according to claim 9, wherein said fastening means comprises:

(a) an elastic strap secured to one end of said band, said strap having a free end; and

(b) a hook and loop type fastener secured to the free end of said strap for cooperation with said outer layer of said band proximate the opposite end thereof.

11. The thermal collar according to claim 8, further comprising an opening formed in one of said ends and communicating with said recess to allow easy insertion and removal of said cold pack.

12. The thermal collar according to claim 11, further comprises flap means provided in said opening for preventing said cold pack from inadvertently sliding out of said recess.

13. The thermal collar according to claim 11, further comprising longitudinal slit means communicating with said opening and said recess for facilitating insertion and removal of said cold pack.

14. The thermal collar according to claim 13, further comprising second fastening means for securing said slit means in a closed configuration so that said cold pack remains in place when said collar is in use.

15. The thermal collar according to claim 8, wherein said outer layer comprises a thermal insulating material and said inner layer comprises a non-insulating material.

16. A thermal jacket for chilling a product stored within a container, said jacket comprising:

(a)

a flexible band for encircling said container, said band including

an outer layer for facing away from said container, said outer layer being formed of thermal insulating material,

an inner layer for contacting said container, said inner layer being formed of non-insulating material,

a top edge,

a bottom edge,

a cavity formed between said inner layer and said outer layer; and

(b) a flexible cold pack carried within said cavity.

17. The thermal jacket according to claim 16, further comprising support means secured to said bottom edge for supporting the bottom of said container.

18. The thermal jacket according to claim 17, wherein said support means comprises an elastic band having a pair of opposite ends, said ends being secured to diametrically opposed locations along said bottom edge.

19. The thermal jacket according to claim 17, wherein said support means comprises a flexible floor entirely covering the bottom of said container, said floor comprising:

(a) an outer layer for facing away from said container;

(b) an inner layer for contacting the bottom of said container;

(c) a cavity formed between said inner layer and said outer layer; and

(d) a cold pack carried within said cavity.

20. The thermal jacket according to claim 19, further comprising tightening means provided in said top edge for tightening said top edge to conform to containers of various sizes.
