System for maintaining desired heated or cooled beverage for extended duration

Abstract

A system for heating or cooling a liquid beverage and maintaining desired range of drinking temperature is described by utilizing a container having a concave shape for the body of the container, a converging neck portion with cylindrical chimney with threaded sleeve that receives a threaded closure for closing and sealing the cap. The type of threads or closing method in not novel nor claimed as part of the invention, but rather the combination of thinness between the front side of the container and rear side of the container, the height and width aspect ratio, the concave shape in conjunction with a complementing-shaped protective insulating and heat reflecting sleeve, and temporary heat source or cooling source. The shape of the container allows the liquid contents of the container to be rapidly heated or cooled, with the heated or cooled state retained for an optimal duration by application of the thermally insulative and thermally reflective sleeve, which includes as a benefit of the shape of the container and sleeve, a designed-in potential space for application of a precisely sized temporary heat source or cooling source which maintains the temperature of the contents of the container in a desired heated or cooled state.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to thin wall metal beverage cans, glass or plastic beverage containers, and in particular to beverage containers having a threaded neck portion for receiving a threaded closure cap to seal the contents of the container.[0003]2. Description of the Prior Art[0004]Aluminum cans are now widely used in the packaging of beer, soft drinks, etc. and these are typically shaped as a cylinder. Although the standard aluminum cans offer a number of advantages for the beverage suppliers, such as low cost, excellent barrier properties, recyclability, etc., there is at present a significant interest in reclosable / resealable cans with an extreme oval, or concave shape for certain market segments.[0005]There have been many attempts to design a reclosable can, such as U.S. Pat. No. 7,171,840 and U.S. Pat. No. 7,261,216. PCT Publication No. WO 99 / 10242 published Mar. 4, 1999 shows yet another form of resealable can c...

AI Technical Summary

Benefits of technology

The present invention is about a special metal beverage container that can be re-closed after being heated. The container has a concave shape, which allows it to be enclosed in a thermally insulating and reflective sleeve. The space between the container and the sleeve can be filled with a disposable heat source or cooling packet to maintain the optimal temperature of the beverage. This container can be used with various heating methods, such as a toaster or microwave, and keeps the beverage hot for a longer period of time. Overall, this invention provides a convenient and efficient way to enjoy hot or cooling beverages.

Problems solved by technology

Rigorous testing has shown that the contents of the container will maintain the desired temperature up to 1 hour longer than a container without the benefits of the system in this application.
