Heating container

Abstract

The invention relates to a portable heating container, in particular to a self-heating or solid alcohol-heating container. The container of the invention comprises a first cavity and a second cavity, wherein the first cavity is used for containing the contents of the container; the second cavity is used for containing a heating body; the second cavity is closed by a base; the first cavity is closed by a container cover; the first cavity is made of a heat conducting material and the surrounding wall of the first cavity is provided with a spiral groove; the inner wall of the second cavity is coated with a fire-retarding and thermal-insulation layer; the outer wall of the second cavity is provided with a handle; the base is sealed and clamped on the lower end of the second cavity and sinks upwards; the inner wall of the second cavity is provided with upper and lower two layers of protrusions which protrude radially and inwards; the upper layer of protrusions are used for auxiliary support of the first cavity; a cuspidal screw rod capable of rotating by using a nut positioned in the center of the base is arranged in the base; a small hole is formed on the upper part of the second cavity; and before heating, the small hole is closed by a unidirectional closing piece, and when the internal pressure of the second cavity reaches 12kpa during heating, the unidirectional closing piece is opened.

Description

Technical field: [0001] The invention relates to a portable heating container, in particular to a container that can be self-heated or heated with solid alcohol. Background technique: [0002] There are many forms of self-heating container solutions. According to its basic working principle, it is basically divided into three categories. The most common one is that two substances capable of exothermic reaction (usually water and quicklime) are separately placed at the bottom of the tank with a diaphragm, and the diaphragm is broken when needed. , to make it mix and generate an exothermic reaction for heating; the second is to directly use an open flame to heat at the bottom of the tank. [0003] However, the disadvantage of the first solution is that it is easy to misuse, cause the two substances to be accidentally mixed for heating or easily cause the reaction substance to fail, and generally can only be used once, and when the reaction substance mixes and produces an exot...
