Abstract
Freezing gel containment structure is comprised of a plurality of adjacent tubes. The tubes are secured in adjacent edgewise relationship and each is separately filled with freezing gel. The tubes are tall and narrow and are sufficiently filled so that they have some cylindrical structural strength. The containment structure comprised of the plurality of tubes is strong enough to stand.
Claims14
A freezing gel containment structure comprising:
- first and second sheets of flexible thermoplastic synthetic polymer composition material, said sheets lying in a substantially face-to-face relationship, said sheets being sealed together adjacent their adges and being sealed together at intermediate parallel upright seal lines to form a plurality of adjacent upright tubes, said tubes having freezing gel therein, said tubes being sufficiently narrow in a direction transverse to the upright direction with respect to their height in the upright direction and being sufficiently filled with freezing gel that each of said tubes is self-supporting when standing in the upright direction, said sheets with said tubes and said freezing gel filling forming a panel which will stand in the upright direction and which is flexible along said intermediate seal lines so that it is bendable around an upright axis.
A freezing gel containment structure comprising;
- first and second flexible thermoplastic synthetic polymer composition material sheets lying adjacent each other in substantially face-to-face relationship;
- edge seals between said sheet around the edges thereof to seal said sheets together adjacent their edges, said sheets having an upright direction and a lateral direction at right angles thereto;
- a plurality of intermediate seals lines between said sheets in an upright direction to define a plurality of tubes between said sheets in an upright direction, said tubes being long in the upright direction as compared with the width thereof in the lateral direction;
- feeezing gel within said tubes to form a panel, said freezing gel sufficiently filling said tubes so that said panel is self-supporting in the upright direction;
- and
- means for securing said panel around a beverage container in a direction such that the upright direction of said panel extends in the upright direction of the container so that, upon precooling of said freezing gel containment structure, the beverage container can be maintained cool by said containment structure.

The method of making a freezing gel containment structure comprising the steps of:
- placing first and second sheets of flexible thermoplastic synthetic polymer composition material adjacent each other in substantially face-to-face relationship;
- heat-sealing the sheets together around adjacent their edges and along intermediate seal zones substantially parallel to each other and in an upright direction to form tubes between the intermediate seal zones and to form flexible spaces between the tubes along the intermediate seal zones;
- filling the tubes substantially full of freezing gel so that, when filled and sealed and stood in the upright direction, the tubes are substantially rigid and self-supporting to form a panel while the panel remains flexible along the intermediate seal zones so that the panel can be wrapped about a curved beverage container;
- and
- providing attachment means attached to the panel for holding the panel in embrace around a beverage container.
