Abstract

PURPOSE:To minimize the escape of heat to the outside and substantially reduce the amount of exothermic reactants used by providing the outer layer of an insulating film on the outer periphery of a heating container which generates heat by applying an external force to the first and second exothermic reactants retained out of contact from each other so as to bring such reactants into contact with each other. CONSTITUTION:When using a heat container 10, a first intermediate layer 12 is broken and released by striking a heat container 10 against the corner of a desk or the like with a suitable place thereof held with the fingers. A first exothermic reactant 16 intrudes into a second exothermic reactant 17 for contact and combination therewith, whereby the first exothermic reactant 16 (e.g. water) and the second exothermic reactant 17 (e.g. quicklime) undergo an exothermic reaction to generate heat. Since the heat so generated is prevented from escaping to the outside by the outer layers 15A and 15B of the first and second exothermic reactants, an object received for heating in a space defined by the inner layers 11A and 11B of the first and second exothermic reactants can be heated efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Purpose of the invention [Field of industrial application] The present invention relates to a heating container, and in particular, to the outside of a bag-like container containing an object to be heated. The second exothermic agent is held in a non-contact state, and when used, an external force is simply applied to the first exothermic agent. The second exothermic agents are brought into contact with each other to cause an exothermic reaction, and the PJr
This invention relates to a heating container having an outer layer made of 8-material film.

[Prior Art] Conventionally, this type of heating container has a bag-like container made of a moisture-proof film, and a water-impermeable film is provided on the inner surface of the container to form a heat-generating agent storage area. 1st in the area. The second exothermic agent is housed in a non-contact state, and when used, the first exothermic agent. It has been proposed that the second exothermic agents are brought into contact with each other and the object to be heated is heated by the heat generated at that time.

[Problems to be solved] However, in conventional heating containers, a water-impermeable film is provided on the inner surface of a bag-like container made of a moisture-proof film to form a heat generating agent storage area. 1st in the area. Since the second exothermic agent was merely contained and catalytically combined during use, the first exothermic agent. There is a drawback that the heat generated by the second exothermic agent escapes to the outside, and in order to sufficiently heat the object, it is necessary to use the first exothermic agent. There was a drawback that a large amount of the second exothermic agent was required.

Therefore, in order to solve these drawbacks, the present invention aims to provide a heating container in which a heat insulating film is provided as the green outer layer.

(b) a first intermediate layer formed of a water-impermeable film and bonded peripherally to the first internal layer; and (c) peripherally joined to the first intermediate layer. (d) a first outer layer joined to the second intermediate layer and formed of a thermal insulating film; (g) a second outer layer bonded to the inner layer of CD and formed of a 1tIr thermal material film; a first heat generating agent housed between the CD first inner layer and the first intermediate layer; 1. The second intermediate layer is housed between the first and second intermediate layers.
A heating container comprising a second exothermic agent that causes an exothermic reaction with the first exothermic agent when the intermediate layer of the heating container is opened.

[Function] The heating container according to the present invention includes a first heating container for forming a space for accommodating an object to be heated. A first intermediate layer is arranged with respect to one of the second inner layers, for example, the first inner layer, to form a space for accommodating the first exothermic agent.

and a second intermediate layer is arranged with respect to the first intermediate layer to form a space for accommodating the second exothermic agent, and the second inner layer and the second intermediate layer are made of a heat insulating material film. After disposing the outermost layer, by opening the first intermediate layer, the first. Second 9. ? When heat is generated by bringing the 8 agents into contact with each other, it acts to prevent the heat from escaping to the outside as much as possible, which in turn serves to efficiently heat the object to be heated. This serves to significantly reduce the amount of the second exothermic agent used.

[Example] Next, the present invention will be specifically described with reference to the accompanying drawings.

FIG. 1 is a cross-sectional perspective view showing an embodiment of the heating container according to the present invention.
