Portable Bottle with Refrigeration/Heater System

Abstract

An inexpensive portable bottle capable of keeping fluid (such as beverage) cold or hot for several hours. The portable bottle comprises a cap, and two containers: an upper fluid container designed to keep fluid (such as beverage) inside it; and a lower sealed container completely sealed and filled with a substance that remains cold or hot for several hours. The portable bottle is designated to be placed inside a refrigerator or microwave or similar devices until the substance, located inside the lower sealed container, gets cold or hot. Afterwards, users can place beverage inside the upper fluid container, close it with the cap and carry the portable bottle with them for later consumption of the beverage. The portable bottle will keep the beverage cold or hot for several hours.

Description

FIELD OF THE INVENTION

The present invention generally relates to portable bottles, specifically to an inexpensive portable bottle capable of keeping fluid (such as beverage) cold or hot for several hours.

BACKGROUND OF THE INVENTION

As “Safety Precaution”, the U.S. Food and Drug Administration advises to “Use cold packs in lunch boxes to keep sandwiches, other perishables, and beverages cold.” In addition, many beverages tend to taste better and to be more refreshing when they are cold, especially during the summer.

On the other hand, many other beverages tend to taste better when they are hot, especially during the winter.

No inexpensive and portable prior art addresses the problems derived from the interruption in the cold-chain or hot-chain when users transport their beverages. Accordingly, there is a need for an inexpensive portable bottle capable of keeping fluid (such as beverage) cold or hot for several hours.

Further objects and advantages will become apparent from a consideration of the ensuing description and drawings.

SUMMARY

The present invention is an inexpensive portable bottle capable of keeping fluid (such as beverage) cold or hot for several hours. The bottle can be easily carried in a hand, handbag, briefcase, backpack or any similar device, for later consumption of cold or hot beverage.

The invention will be better understood after a study of the detailed description. Such description refers to the annexed drawing.

DETAILED DESCRIPTION

Preferred Embodiment

A numeral 1 designates the removable cap of the bottle: a cap removable from the top of the upper fluid container of the bottle.

A numeral 2 designates the upper fluid container of the bottle: a cylindrical container with a relatively narrow neck designed to keep fluid inside it.

A numeral 3 designates the lower sealed container of the bottle: a cylindrical container, smaller than the upper fluid container, completely sealed and filled with a substance that remains cold or hot for several hours after kept at low or high temperatures respectively.

A numeral 4 designates the substance, inside the lower sealed container, that remains cold or hot after kept at low or high temperatures.

A numeral 5 designates a narrow opening at the top of said upper fluid container.

A numeral 6 designates the sidewall of the upper fluid container.

A numeral 7 designates the sidewall of the lower sealed container.

A numeral 8 designates the wall between the contiguous upper fluid container and lower sealed container.

Operation:

The operation of the portable bottle will be described. The removable cap (designated with numeral 1) keeps the narrow opening (designated with numeral 5) sealed when closed, and can be removed to fill the upper fluid container (designated with numeral 2) with beverage or to dispense beverage from said upper fluid container.

The portable bottle is designated to be placed inside a refrigerator or microwave or similar devices until the refrigerant substance (designated with numeral 4) inside the lower sealed container (designated with numeral 3) gets cold or hot.

Afterwards, users can put beverage inside the upper fluid container (designated with numeral 2) through the narrow opening (designated with numeral 5), close it with the removable cap (designated with numeral 1) and carry the portable bottle with them for later consumption of the beverage. The portable bottle will keep the beverage cold or hot for several hours.

CONCLUSION, RAMIFICATIONS AND SCOPE

While the above description contains many specificities, these should not be construed as limitations on the scope of the invention, but as exemplifications of the presently preferred embodiments thereof. Many other variations are possible within the teaching of the invention.

Thus, the scope of the invention should be determined by the appended claims and their legal equivalents, and not by the examples given.

Claims
