Exothermic semi-rigid plastic stick

Abstract

A semi-rigid, portable, warming device contains chemical reactants that produce heat when mixed. The warming device includes at least two chambers, which contain the chemical reactants separately, until a force is applied to cause the reactants to mix.

CROSS-REFERENCE TO RELATED APPLICATION DATA[0001]This application claims the benefit of priority of Provisional U.S. Patent Application Ser. No. 61 / 348,990, filed May 27, 2010.BACKGROUND OF THE INVENTION[0002]This invention pertains to a semi-rigid plastic stick that contains a formulation of chemicals that, when mixed together, produce an exothermic reaction. More specifically, the invention pertains to a bendable, semi-rigid plastic stick that contains chemicals separated from one another that, when mixed together, produce an exothermic reaction.[0003]There are many situations where a semi-rigid, self-contained heating apparatus would be beneficial. For example, in winter weather activities where the user wants the heat to be directed to a certain area and for the heat source to remain in place.

AI Technical Summary

Benefits of technology

[0009]A portable heat device according to embodiments of the present invention contains chemicals separated from one another that, when mixed together, produce an exothermic reaction. According to a preferred embodiment, the portable heat device is in a form of a stick that is durable and has a specific shape to allow the user to position it without fear of undue shifting. Further, the device is chemical in nature, and thus is portable and negates the risk of shock or the like associated with electrical items.

Problems solved by technology

Current technologies are insufficient at either producing a self-contained, non-electric heat, or at directing the heat to a particular area without the concern of the heating element shifting in position.

Unfortunately such a product has little to no definitive shape, and as such the position of the heating element inside shifts, causing the user to have to continuously reshape the item and move it back into an optimal position.

However, these items require a power source, such as an external electrical connection (e.g., access to a 120V electrical outlet) to operate, making them disadvantageous to individuals not wanting an electrical device.

Further inherent in an electrical device, especially of a heating nature, is the danger of causing a spark or flame through some electrical failure, or the possibility of electric shock.

One drawback with such an item is that a user can not select when to have the heat released from the item.
