Background of the Invention Water is an essential component for life. Ice is a convenience. Ice is widely available from either an ice tray in one's own refrigerator or in large bags of ice cubes. Ice trays can not be transported or stored without refrigeration for readily apparent reasons. Bags of ice cubes have the disadvantage that the cubes tend to agglomerate, particularly if the ice cubes are allowed to melt and then are refrozen. Therefore, to the extent the bags of ice cubes must be transported, it can only be done in a refrigerated truck.

The present invention overcomes the problems associated with ice trays and bagged ice cubes by delivering a clean individually packaged aqueous product that can be repeatedly frozen and thawed.

Summary of the Invention The present invention relates to a liquid container containing a plurality of enclosed cells formed between at least a first layer and a second layer of polymeric material. Each enclosed cell contains essentially less than about 2 fluid ounces of an aqueous- based solid or liquid. Preferably, each enclosed cell contains less than about 1 fluid ounce of an aqueous-based solid or liquid.

Each enclosed cell can be shaped into substantially a cube or decorative shapes, such as a seashell, or textured.

The aqueous-based solid or liquid preferably is at least 98% water and can optionally further contain viscosity modifiers, flavorings, fragrances, colorants and preservatives. In a more preferred embodiment, the aqueous-based solid or liquid is distilled water.

A particularly preferred embodiment provides a first layer of polymeric material that has been thermoformed into a substantially cubic, decorative or textured form and the second layer of polymeric material is a flexible layer that has been removably sealed to the first layer of polymeric material.

In a still further embodiment, the first layer and second layer of polymeric materials are perforated. The first layer and second layer of polymeric materials are preferably perforated to allow separation of an individual enclosed cell from the remainder of the plurality of enclosed cells.

Detailed Description of the Invention The present invention begins with a packaging system containing individually wrapped liquid materials. The packaging system can be in the form of a blister package, thermoformed package or bubble pack. The packaging system must be capable of forming closed cells to hold a liquid or frozen aqueous material. Preferably, the closed cells are separable into individual cells and/or rows of individual cells.

A preferred packaging system has a unitary structure containing a plurality of individual portion containers shaped to hold about 0.5 fluid ounces of water. The system is preferably is made by thermoforming a polymeric material, such as polystyrene, polyvinyl chloride, and polypropylene, having a thickness of 0.010 inches. A cover for the structure can be a transparent, opaque, or pigmented polymeric material, such as polyester and mylar, or foil material.

The cover is secured to the unitary structure using either an adhesive or the application of heat to form a bond between the cover and the unitary structure. The cover is preferably thin enough to be bent and yet strong enough to be pulled back off of the unitary structure to expose the contents therein.

The contents of the structure is preferably an aqueous-based liquid. made up of greater than about 90% by weight of water, more preferably greater than 98% by weight water. Viscosity modifiers, flavorings, colorants and preservatives can be added. A more preferred liquid provided in the structure is substantially pure water. Water that the average consumer can obtain from a public water supply or purchase in bottle form would be considered to be substantially pure. The most preferred contents of the structure is distilled water.

Preferred embodiments of the present invention relating to novel liquid containers and methods for using the same have been described above. Those skilled in the art having the benefit of the teachings presented in the foregoing will recognize modifications and other embodiments. Therefore, it is understood that the invention is not limited to the specific embodiments disclosed herein, and that modifications and other embodiments are intended to be within the scope of the appended claims.
