## Abstract

A foldable or flexible wrap is disclosed herein having a pair of plastic-like sheets selectively joined together at critical locations so as to provide fold lines or paths subject to flexure whereby the wrap may be wound about an article intended to be maintained in a cool environment. One sheet of the pair is flat while the other is provided with a plurality of spaced-apart pockets containing a freezable gel or substance, such as water. The pockets are arranged in a defined pattern adjacent to the fold lines or paths so that the wrap may take many different configurations when folded about articles of different shapes and sizes.

## Claims

### Claim 1

A foldable freeze wrap comprising:
a first support sheet of material;
a second compartmented sheet of material attached to said support sheet and having a plurality of individual and separate pockets;
said pockets arranged in spaced-apart relationship and each of said pockets enclosing a freezable product which totally occupies the interior of each of said pockets;
selected fold areas of said sheets specifically defined as being between said pockets joined together by a heat seal attachment and said selected fold areas constituting fold lines about a linear hinge axis so that said sheets are foldable over to accommodate wrapping about an article to be chilled;
said freezable product is a gel and said sheets are composed of a freezable material whereby both gel and sheets may be frozen prior to wrapping about the article to be chilled;
said wrap being foldable in its frozen condition and adapted to assume the shape of the article intended to be chilled;
each of said gel occupied pockets are configured in the shape of a diamond in plan view and a pyramid in side elegational view;
said selected fold areas include hinge axis crossing along X--X and Y--Y axis between adjacent ones of said separate and individual diamond shaped pockets.
