Benefits of technology

"The patent describes a self-heating beverage cup that has a container portion for holding liquid. The container has two layers and a space between them where chemicals can be stored. The chemicals release heat when mixed with water. The cup has a string to remove the chemicals from the bottom. The cup may also have a bladder to hold water and a metal part to transfer heat from the chemicals to the water. The technical effect of this invention is a convenient and efficient way to heat beverages quickly and easily."

Problems solved by technology

We have been enjoying hot liquids since the dawn of time but the process of preparing them is still laborious and generally requires a heat source which is not always convenient.
Also, some products are available that can be self warmed in a can or bottle, but many people prefer to prepare their own beverage just the way they like which is not possible using prepared beverages.

Embodiment Construction

[0010]In the following detailed description of the invention, reference is made to the drawings in which reference numerals refer to like elements, and which are intended to show by way of illustration specific embodiments in which the invention may be practiced. It is understood that other embodiments may be utilized and that structural changes may be made without departing from the scope and spirit of the invention.

[0011]Referring to FIGS. 1 and 2, a self heating beverage cup 100 is shown having an outer wall 110 and an inner wall 115 with a water holding portion 145 disposed between walls 110 and 115 respectively along a top portion of cup 100. Removable seals 125 and 130 are located on the bottom of water holding portion 145 and connected with a string 120. When a user pulls on string 120, removable seals 125 and 130 are removed and allows the water to flow down and mix with calcium oxide 140 located along the bottom of cup 100.

[0012]Because the reaction is exothermic, heat is g...

Abstract

A self heating beverage cup has a container portion adapted to hold a selected liquid. The container portion is double walled and has a water holding portion disposed between the walls along a top portion and a chemical holding portion disposed along a bottom portion. The water holding portion has two removable seals disposed on a bottom portion so that when removed, the water flows down to mix with a chemical in the chemical holding portion. The chemical is calcium oxide which releases heat when mixed with water. A string is provided to allow the user to remove the two removable seals by pulling therein. In one embodiment, a bladder is provided to contain the water. A metallic portion thermally connects the chemical holding portion to a portion of the container portion so that heat is transferred into the liquid therein.

Description

BACKGROUND OF THE INVENTION[0001]We have been enjoying hot liquids since the dawn of time but the process of preparing them is still laborious and generally requires a heat source which is not always convenient. The invention of the microwave oven greatly decreased the time required to prepare hot liquids such as tea or hot chocolate, but it still requires having access to a microwave.[0002]Also, some products are available that can be self warmed in a can or bottle, but many people prefer to prepare their own beverage just the way they like which is not possible using prepared beverages.[0003]There is a need for a self heating beverage cup that is convenient and easy to use that allows a user to prepare a beverage in a customized manner.SUMMARY OF THE INVENTION[0004]A self heating beverage cup has a container portion adapted to hold a selected liquid. The container portion is double walled and has a water holding portion disposed between the walls along a top portion and a chemical...
