Description

[Detailed description of the invention] This invention relates to a portable heating container, and more specifically, to a portable heating container that can continuously heat an object to be heated using an oxidizing exothermic agent that does not use electricity or fire. It is something.

When heating something, heat sources that can be used nearby include heat obtained when burning solar carbide or Joule heat obtained when electricity is passed through a resistor.

Such a heat source cannot be carried around and used anywhere because its use is limited to a limited number of locations.

Therefore, most of the heat sources currently used for portable equipment use oils and fats in solid or liquid form, and those that use small gas cylinders, but these burn oils and gases and are therefore dangerous to handle. There is a drawback.

The purpose of this invention is to eliminate the above-mentioned drawbacks.The purpose of this invention is to form a recess at the lower end of the external vertical surface of a double-walled container, and in this recess, a number of air holes are provided in a sloped container. A shaped protrusion is fitted to the upper end of the fitting part, and the lower end of the container fitting part is locked to the end opposite the hinge of a pedestal hinged to the lower end of the container fitting part. A portable device, characterized in that an engaging piece is provided, an upwardly curved elastic member is provided on the bottom cover of the cradle, and an oxidation heating element is sandwiched between the elastic member and the bottom surface of the container. A heating container is provided.

An embodiment of this invention shown in the drawings will be described in detail below.

The portable heating container of this invention consists of a pedestal 1 and a container 2, as shown in Figs. A container fitting piece 11 having a protrusion 10 formed therein, and a tapered sloped surface 12 extending toward the lower opening side are formed with a number of air holes 13, which are connected to a part of the edge of the opening by a V-cut hinge 14. Then, a heating element containing an oxidizing exothermic agent in a bag inside and an elastic member 15 having a curved upper part to be pressed against the bottom surface of the container fitted on the pedestal are integrally attached at a position facing the V-cut hinge. Bottom lid 1 with a locking piece 16 that can be locked to the outer edge of an inclined surface
7, and the container fitting part 11 is provided with a cut groove 19 of a constant width as shown in FIG.
A plurality of containers are provided so that the container can be easily attached and detached.

The pedestal 1 described above is made of heat-resistant hard plastic by casting.

The container 2 has a container body 21 smaller than the inner diameter of the container fitting portion 11 by drawing a metal such as aluminum which is easy to work and has good thermal conductivity, and has a curl portion 22 that curls outward on the opening edge of the container body 21, which is smaller than the inner diameter of the container fitting portion 11. In addition, a gap 25 approximately equal to the difference between the inner diameter of the container fitting part 11 and the outer diameter of the container body is formed between the corner where the internal vertical surface 24 rises from the bottom surface 23 and the vertical surface. It has a double wall with an external vertical surface 26 made of plastic which is attached in such a manner that the external wall 26 is formed with a recess 27 into which the projection 10 described above is fitted.

The containers shown in FIGS. 2 and 4 have a substantially reduced height.

The portable heating container of this invention is constructed as described above, and examples of the use of this container will be described below.

First, attach the container 2 to the pedestal 1 so that the convex part 10 fits into the concave part 27, open the bottom cover 17, and open the oxidation heating element housing part 18.
The heating element 3 containing an oxidizing exothermic agent prepared by mixing powders of iron, carbon, cellulose, and chloride and water in appropriate proportions in a bag body 32 is placed inside the bag body 32 after being removed, and the bottom cover 17 is inserted into the bag body 32. By closing the locking piece 16 until it locks on the outer edge of the inclined surface 12, the heating element 3 is pressed against the bottom surface 23 of the container 2 by the elastic member 15, and the oxygen in the air entering through the air hole 13 and heat generation are generated. The heat generated by the chemical reaction with the body 3 is directly conducted to the container body 21 and heats it to about 50-80°C.

As shown in Fig. 2, the object to be heated may be placed directly into this container 2 and used as a cup, or the object to be heated may be placed in another container b (a sake bottle in this example) as shown in Fig. 4. From above container 2
You can also use it as a sake bottle hakama by putting it inside and heating it.

Particularly in this case, it is more effective if it is used to prevent the heat from freezing.

If the reaction slows down, open the bottom cover 17, take out the heating element 3, massage it again, and put it back in. The reaction will become active again and the heated object will be heated (kept warm) for 20 to 24 hours. It is possible.

As described above, this invention has the following effects.

1. Since the protrusion 10 can be removed from the recess 27 and the double-walled container 2 can be easily separated from the container fitting part 11 of the pedestal 1, the container can be used as a heat-retaining cup or a sake bottle hakama.

2. Since the container fitting part 11 of the pedestal 2 consists of an inclined surface 12 having a large number of air holes 13, the stability of the entire container is good.
Since it has a large air holding capacity and high air exchangeability, it improves the action of the oxidizing heating agent.

3. Since the bottom cover 17 of the pedestal 2 and the upwardly curved convex elastic member 15 can be opened downward as shown in FIG. Member 15
While pressing the heating element against the bottom surface 23 of the container 2, the heating element can be held in an appropriate position to allow the chemical reaction to take place sufficiently.
