Abstract

A cooling device has a flexible foam insulating layer with a cooling surface. A plurality of distinct cavities spaced from each other are located adjacent the cooling surface in the insulating layer. A cooling fluid is contained within each cavity. The device is cooled to freeze the cooling fluid, and an object such as a bottle is placed within the cooling device to be cooled.

Claims

1. A flexible cooling device capable of conforming to irregular shaped surfaces comprising:

an elastic insulating layer having a cooling surface;

a plurality of discrete sealed cavities spaced from each other with sufficient portions of the elastic layer between the spaced cavities to provide sufficient flexibility to allow the cooling surface to conform to irregular shaped surfaces and imbedded in the insulating layer adjacent the cooling surface; and

a cooling fluid for freezing within the cavities.

2. The cooling device of claim 1 and further comprising a flexible liner attached to the cooling surface of the elastic insulating layer.

3. The device of claim 2 wherein the flexible liner is made of a flexible synthetic plastic.

4. The device of claims 1 or 2 wherein the insulating layer is in a cylindrical configuration with the cooling surface forming an inside surface of the cylinder and having one end capped with an insulating material, the device having a cup configuration.

5. The device of claim 1 and further comprising fastening means for retaining the cooling device on an object to be cooled, the fastening means being attached to a surface opposite the cooling surface such that when the device is placed around the object the cooling surface is adjacent to the object.

6. The device of claim 1 wherein the insulating layer is made of a foam rubber.

7. The device of claim 1 wherein the cooling fluid is a refreezable gel.

8. The device of claim 1 wherein the cooling fluid is a refreezable fluid.
