Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a heating element utilizing the exothermic reaction of quick lime and water, and in particular, it is housed in a container together with food and the food is heated and heated. To a heating element suitable for.

<Prior Art> A heating container for food or the like utilizing the reaction of quick lime and water has been known for a long time, for example, Japanese Patent Publication No. 35-10470.
In recent years, Japanese Utility Model Laid-Open No. 61-35635 has been known as a container for foods. The container shown in Japanese Utility Model Publication No. 61-35635 has a bag in which quicklime and water are individually packaged at the bottom of the container, and the bag is opened by the opening means attached to the bag to bring them into contact with each other. .

<Problems to be solved by the invention> By the way, quicklime and water generally react rapidly and generate a high temperature, so that handling thereof is not easy. Actual Kaisho
The container disclosed in 61-35635 has a high risk of localized overheating due to uneven contact of quick lime with water due to deviation of quick lime due to handling such as transportation.

On the other hand, quicklime is stored in a bag made of a water-permeable material such as a non-woven fabric, and is stored in a container by stacking it with a separate water bag, but the above-mentioned danger has not been solved. Further, this danger similarly occurs when the container is tilted and used.

In view of the above problems, the present invention provides a heating element that allows quick lime and water to come into contact with each other as evenly as possible, does not cause local overheating, and is easy to handle.

<Means for Solving the Problems> That is, according to the present invention, a reaction tray comprising a substantially spherical accommodating portion and a two-tiered flange provided at an opening of the accommodating portion has a granular shape in the accommodating portion. Accommodating the quicklime of the naked,
The lower flange of the two-stage flange is sealed with a four-way seal water bag equipped with an opening means, and a breathable material is stretched on the upper flange, and the water bag opening means is led out of the reaction tray. It is a heating element.

<Operation> The reaction tray of the present invention has a substantially spherical accommodating portion and accommodates the bare granular quicklime. Although the quick lime moves when the heating element is tilted, the storage state of the quick lime does not change because the storage portion has a substantially spherical shape. The water used for the reaction is supplied in a state of being poured onto the quick lime by opening the water bag for sealing the opening of the reaction tray by the opening means.

When water and quicklime come into contact with each other, an exothermic reaction occurs, and the generated heat is generated through air or by steam generated during the reaction.
Heat food etc.

<Example> Next, the present invention will be described with reference to the drawings. FIG. 1 is a sectional view showing an embodiment of the present invention, and FIG. 2 is a partially cutaway plan view of the same embodiment.

The reaction tray (1) includes a substantially spherical container (11) and the container.
Lower flange (12) provided at the upper end of (11), and wall (1
It is composed of an upper flange (14) provided via the (3). The wall (13) is provided with holes (15).

The accommodating portion (11) accommodates granular quicklime (2) in a naked state.

The water (3) used in the reaction with the quicklime (2) is the opening means (35).
It is stored in a water bag (31) consisting of a four-sided sealed bag equipped with. The water bag (31) has a seal (32) on the lower flange.
It is joined to (12) to seal the housing (11).

The unsealing means (35) for the water bag (31) comprises a strip-shaped destruction guide member (37) attached to a piece (36) formed by a notch (38) provided in the seal portion (32). One end of the destruction guide member (37) is
Guided to the outside from the hole (15) provided in the wall (13),
It is provided so that it can be operated from outside the heating element.

Since the water bag (31) is destroyed by the opening means (35),
A tearable material is used, and a plastic film, a metal foil, or the like can be used, and a stretched plastic film is preferable.

Further, the seal portion (32) of the water bag (31) and the lower flange (12) can be joined by heat sealing, ultrasonic sealing or the like, but an easily peelable adhesive near the opening means (35). It is desirable to make it easy to open by using such as.

The upper flange (14) has a breathable material (4) made of paper, non-woven fabric, microporous membrane, or perforated plastic film.
Is stretched and seals the opening of the reaction tray (1). This breathable material (4) prevents quick lime etc. from directly touching food etc. and spilling quick lime to the outside, but does not prevent warm air and water vapor generated by the reaction from being released from the heating element to the outside. . One end of the destruction guide member (37) is
It may be led out from between the breathable material (4) and the upper flange (14).

To use the heating element of the present invention constructed as described above, it is only necessary to pull the destruction guide member (37). By this operation, the water bag (31) is destroyed, water (3) is poured from the top of the quicklime (2), and the reaction starts. Water vapor generated by the reaction is
It is released to the outside through the breathable material (4).

<Effect of the device> Since the heating element according to the present invention has the above-described structure, there is no substantial deviation of the quick lime due to handling during transportation or inclination during operation, and water is on the quick lime. It is safe because it pours from the ground so that the reaction occurs uniformly and no local overheating occurs.

In addition, since the accommodating portion of the reaction tray is completely sealed with a water bag before use, quick lime is not likely to deteriorate due to moisture absorption and can be stored for a long period of time.

Furthermore, since the reaction tray is sealed with a breathable material, quick lime and the like do not come into direct contact with food, human bodies, etc., and it is safe for the user.

In addition, the usage is simple and easy to handle.
