Description

[Detailed Description of the Invention] "Industrial application field" The present invention relates to a heating and heating container that heats foods and drinks by heat generated by the hydration reaction of an exothermic agent. The present invention relates to a heating and heating container that can be uniformly heated and has a high degree of freedom in appearance design.

"Prior Art" Conventionally, as this type of heating and heating container, for example, Japanese Patent Laid-Open No. 1-
The one described in Japanese Patent No. 265920 is known.

This heating and heating container is formed by accommodating water enclosed in a water bag and a heat generating agent that generates heat by a hydration reaction in a laminated state at the bottom of the container body, and is caused by opening the water bag. The hydration reaction between water and the exothermic agent is configured to heat and heat the food in the food container placed at the top of the container body, but the exothermic agent and the water bag are the bottom of the container body. That is, it was placed and stored on the inner container arranged below the food container.

[Problems to be Solved by the Invention] The above conventional heating and heating container has the following points to be improved.

That is, since the water bag is stored in close contact with the bottom surface of the inner container, when the water bag is opened, the diffusion of water in the inner container is hindered by the water bag and the reaction is biased, such as food. Not only could the stored items not be uniformly overheated, but there was a possibility that the internal container would melt due to a partial abnormal temperature.

Also, although the heat from the hydration reaction is not directly transferred to the bottom of the container body, the upper part of the container body is heated by the steam generated by the hydration reaction, so It was easy to become dangerous and was dangerous. For this reason, the container body must be made of a material that attaches importance to heat insulation. In this case, the workability of the design such as providing a decorative pattern on the surface of the container body is liable to deteriorate. There was a problem that the degree of freedom in external design decreased.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide a heating and heating container capable of uniformly heating stored items and having a high degree of freedom in external design.

[Means for Solving the Problem] The heating and heating container of the present invention comprises water enclosed in a water bag and an exothermic agent that generates heat due to a hydration reaction, and is stored in a laminated state at the bottom of the container body. In the heating and heating container configured to heat and heat the contents by the hydration reaction of the water and the exothermic agent, the container body is an inner container having a bottom surface formed in an uneven shape,
An outer container covering the outer side of the inner body, wherein the heat generating agent and the water bag are arranged on the bottom surface of the inner body.

[Operation] According to the heating and heating container of the present invention, since the bottom surface of the inner container on which the exothermic agent or water bag is placed is formed in an uneven shape, a bag or a water bag for accommodating the exothermic agent on this bottom surface is formed. They do not adhere to each other and they do not interfere with the diffusion of the released water.

Further, since the container body has a double structure of an inner container and an outer container, the entire container body has high heat insulation performance due to the air layer formed between the inner container and the outer container, The outer container does not need heat resistance or heat insulation.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In FIG. 1, reference numeral 1 as a whole is the heating and heating container of this embodiment. The heating and heating container 1 includes a container body 2, an inner plate 3 arranged at an upper portion of the container body 2,
A lid 4 for opening and closing the upper parts of the container body 2 and the inner plate 3.
The outline of the container is composed of and.

The container body 2 is composed of an inner container 5 having a concave and convex bottom surface and an outer container 6 arranged so as to cover the outer side of the inner body. In the case of the present embodiment, the inner container 5 is formed. By forming a plurality of columnar protrusions 7 on the bottom surface of the, the bottom surface is uneven.

Here, the inner container 2 is made of a material having good heat resistance and heat resistance,
For example, the outer container 6 is made of a heat-resistant plastic, a polymer foam material, or the like. Further, the outer container 6 is made of a material that emphasizes designability and low cost, for example, a material obtained by adhering a printing film to paper, and a decorative pattern on the outer surface. Can be easily provided. The inner plate 3 is for storing food and drink placed on the upper surface thereof, and is made of a material having good heat resistance.

Here, the bottom surface of the inner container 5 is not limited to the shape as in this embodiment, but may be, for example, a lattice shape or a shape provided with concentric grooves. It may be uneven so that it does not adhere to the bottom surface of the inner container 5.

In addition, the bottom of the heating and heating container 1, that is, the inner container 5 and the inner plate 3
As shown in FIGS. 1 and 2, a heat generating agent 8 such as quick lime, which generates heat due to a hydration reaction, and water W are stacked between and. That is, a water bag 9 in which water W is enclosed is arranged on the bottom surface of the inner container 5, and the heat generating agent 8 is arranged thereon.

Here, the heating agent 8 is arranged in a state of being housed in a bag body 10 formed of an aluminum sheet or the like and provided with a plurality of small holes 10a. The water bag 9 is formed of a directional film that is a synthetic resin film such as polyethylene, polypropylene or polyester that can be easily torn, and as shown in FIG. It is sealed by the seal portion 11 and has a water-filled portion 12 formed inside thereof.
The side seal part 11 has a notch from the end toward the water sealing part 12.
By providing 13 a part of the seal portion 11 forms a tape piece 14. Further, the water enclosing portion 12 is formed with a recess 12a such that the distance between the tip of the notch 13 and the water enclosing portion 12 becomes a predetermined distance L, whereby the peripheral edge of the water enclosing portion 12 is separated from the notch 13 by the notch 13. It has a concave shape that moves away from it. Here, in the water bag 9, the film forming the water bag 9 has directionality so as to be along the notch 13. Further, the distance L should be set to a minimum value at which there is no possibility that the cut 13 progresses during transportation or the like and the water sealing portion 12 is broken, and specifically, it is preferably about 20 mm.

The water bag 9 is arranged at the bottom of the inner container 5 with the tip of the tape piece 14 pulled out from the other end 9b side of the water bag 9 to the outside of the container body 2. Here, the tip of the tape piece 14 is pulled out through the lower side of the water bag 9.

According to the heating / warming container 1 configured as described above, the notch 13 is advanced by pulling the tip of the tape piece 14 to break the water-filled portion 12, and the water bag 9 is easily opened to hydrate. It is possible to start the reaction and uniformly heat the foodstuffs and the like contained therein.

That is, since a plurality of protrusions 7 are formed on the bottom surface of the inner container 5 to prevent the bottom surface and the water bag 9 from being in close contact with each other, the water W immediately enters the inner container 5 when the water bag 9 is opened. Spread evenly. After that, the water W enters the bag 10 through each small hole 10a at a speed according to its size and number and reacts with the exothermic agent 8, so that the hydration reaction proceeds at an appropriate speed without bias.

Further, when the water bag 9 is opened, the water bag 9 is made of a film having directivity so as to follow the notch 13, and since only one notch 13 needs to be advanced, the notch 13 is very advanced. The water bag 9 is pressed against the heat generating agent 8 or the weight of the stored items and does not move. Therefore, when the tape piece 14 is pulled, the tape piece
The water bag 9 does not move together with the water bag 14 and the opening is not performed, so that the opening is surely performed.

According to the heating and heating container 1 of the present embodiment, the bottom surface of the inner container 5 on which the water bag 9 is placed is formed in an uneven shape, and therefore the water bag 9 does not adhere to the bottom surface and is discharged. The diffusion of the water W is not hindered. Therefore, the discharged water W spreads evenly in the inner container 5, and the contents are uniformly heated without uneven reaction. Further, since the container body 2 has a double structure of the inner container 5 and the outer container 6, the entire container body 2 has high heat insulation performance due to the air layer formed between the inner container 5 and the outer container 6. As a result, the outer container 6 does not need heat resistance or heat insulation. Therefore, the surface of the container body 2 does not become hot even during the reaction, and it is safe, and the outer container 6 is very easily processed such as a decorative pattern.
Makes it easy to make your appearance look good.

The heating and heating container of the present invention is not limited to the above-described embodiment, and the same effects can be obtained even in the following embodiments.

First, although the heating agent 8 is stored, the heating agent 8 may not be stored in a bag of an aluminum sheet, but the heating sheet 8 may be wrapped inside by folding an aluminum sheet having small holes. Further, this surface may be covered with a non-woven fabric.

Secondly, regarding the positional relationship between the water bag and the exothermic agent, the exothermic agent may be disposed on the bottom surface side of the container with the water bag,
Further, two water bags may be arranged above and below the exothermic agent.

[Advantage of Invention] According to the heating and heating container of the present invention, since the bottom surface of the bag containing the exothermic agent or the water bag is formed in an uneven shape, the bag or The water bags are not in close contact and they do not prevent the diffusion of the released water. Therefore, the released water is evenly distributed in the inner container, and the contents are uniformly heated without uneven reaction.

Further, since the container body has a double structure of an inner container and an outer container, the entire container body has high heat insulation performance due to the air layer formed between the inner container and the outer container, The outer container does not need heat resistance or heat insulation. For this reason, the surface of the container body does not become hot even during the reaction, and it is very safe, and processing such as applying a decorative pattern to the outer container becomes very easy, and the appearance of the heating and heating container looks good. The effect that it becomes easy is produced.
