Abstract: An insulative label is provided for a beverage container to reduce heat transfer, particularly heat transfer by conduction from a consumer's hand to the beverage container. The label comprises a dual-ply construction, with a grid pattern placed between the layered materials. Preferably, the label comprises a film base layer secured to the container, the grid pattern comprising an ink and varnish mixture printed over the film base layer, and a laminate top layer secured to the film base layer. Air is trapped in the gaps or spaces between the protrusions created by the grid pattern, and the trapped air insulates the container. The label has a very thin profile, thereby not perceptibly changing the appearance of the label or the container.

Abstract: A system, method and device determine the state of a beverage and communicate information regarding the beverage. A communication device runs an application that determines the start temperature of the beverage to be cooled and sets a desired end temperature. Thermochromatic inks are used on the container label or packaging of the container to convey temperature information. A camera of the communication device senses temperature information of an image of the container. The application then determines an amount of time for cooling the beverage also taking into consideration the type and size of container. The beverage is placed in a cooling device, a timer is initiated by the user, and the application later generates a message indicating the beverage has reached the desired end temperature. The user may link information generated from the application to social networking sites for purposes such as generating invitations to friends within the social network.

Abstract: An insulated and refrigerated beverage transport line provides enhanced temperature control of one or more beverages conveyed through the transport line. A plurality of coolant lines carrying a re-circulated coolant makes contact with the one or more product lines. One or more empty lines, referred to as packers, may be placed between the coolant lines and the product lines to provide a dimensionally stable and tight group of lines that are bundled together. An external insulation is provided over the bundle of lines to further enhance insulation for the beverage being transported through the product lines. At least one dedicated coolant return line may be placed remote from the other lines. The dedicated coolant return line carries the highest temperature coolant found in a beverage transport system. Independent and separate insulation of this dedicated coolant return line prevents inadvertent heat transfer to the one or more product lines.

Abstract: A beverage container is provided, including an integral indicator of a prize for a consumer. The indicator includes two components, namely, a marker and at least one symbol. The marker or symbol is randomly located around the circumference of the container. Alternatively, both the symbol and marker may be randomly located. The resulting orientation of the marker and a pre-selected winning symbol dictates whether the consumer has won a prize. One or more sets of markers and corresponding symbols may be provided on the container to indicate multiple prizes, or a progression of events corresponding to one or more prizes.

Abstract: A method of applying thermal inks to beverage containers includes use of a selected printing process for transferring controlled and discreet amounts of thermal inks to pre-designated portions of a beverage container. In a preferred embodiment, thermal ink(s) are transferred to the opening tab of a metallic container. During manufacturing, the ink can be applied in registered print rows that align with a plurality of corresponding spaced rows of tabs formed in tab stock. Each of the opening tabs has a pre-selected pattern of the applied thermal ink that can be used as a temperature indicator for a beverage within the container. Applying thermal ink to the opening tabs as opposed to larger areas of the container on the sidewall results in reducing the amount of thermal ink used.

Abstract: A thermal barrier liner is preferably spray coated onto the internal surface of a container. The liner is provided in embodiments including a closed cell substrate, a base layer having gas or liquid filled microcapsules, a base layer having microencapsulated solid-liquid phase change material, or combinations thereof. For the closed cell substrate embodiment, when the liner is under pressure within the container prior to the container being opened, the liner maintains a minimum thickness. When the container is opened and as pressure is released within the container, the liner expands to achieve equilibrium. The liner can be supplemented with a foaming agent to create cellular structures. Voids created by the microcapsules enhance the thermal barrier characteristics of the liner. The phase change material changes phase from a solid to a liquid state upon absorbing heat.

Abstract: A beverage container is provided with an integral cooling element to maintain a beverage at a cooled temperature after exposure to a warmer environment. The cooling element incorporates use of solid/liquid phase change material. When the beverage is chilled, the phase change material is maintained in a solid state below its melting temperature. When the beverage container is exposed to a warmer environment, such as during consumption, the phase change material undergoes a phase change thereby absorbing heat from the surrounding beverage. The cooling element can either be attached to the inside of the container or free-floating, but in either case, is in direct contact with the beverage.
