Only a small amount was released from. For this reason, it is not possible to sufficiently steam the stored items, and when the stored items are foods such as sushi, it is not possible to sufficiently bring out the umami of the food items.

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 sufficiently steaming stored items.

[Means for Solving the Problems] In the heating and heating container of the present invention, water enclosed in a water bag and an exothermic agent that generates heat due to a hydration reaction are stored in a laminated state at the bottom of the container body, A heating and heating container configured to heat and heat the contents stored in the inner plate arranged at the upper part of the main body by the hydration reaction of the water and the exothermic agent, wherein the inner plate and the water bag or Between the heat generating agent, a plurality of rod-shaped portions that extend radially outward from the central portion in the same plane, a gap extending from the center side of the inner plate to the peripheral edge on the lower surface side of the inner plate. It is characterized in that a spacer to be formed is provided.

[Operation] According to the heating and warming container of the present invention, the vapor generated by the hydration reaction is generated by the spacer interposed on the lower surface side of the inner plate through the heat generating agent or the void formed in the upper part of the water bag. It is also released from the laminated heat generating agent and the upper surface of the water bag, and a large amount of steam passes between the peripheral edge of the inner plate and the container body and flows into the inner plate, which is stored in the inner plate. It is possible to heat the entire object evenly.

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

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,
The container body 2 and the lid body 4 that opens and closes the upper portion of the inner plate 3 constitute an outline of the container body.

Here, the container body 2 is made of a material having excellent heat resistance and heat insulation performance, such as heat resistant plastic or polymer foam material. 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.

Further, as shown in FIGS. 1 and 2, between the bottom portion of the heating / warming container 1, that is, between the container body 2 and the inner plate 3, an exothermic agent 8 such as quick lime that generates heat due to a hydration reaction and water W. And are stacked and stored. That is, on the bottom surface of the container body 2, a water bag 9 in which water W is enclosed is arranged, 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 a synthetic resin film such as polyethylene, polypropylene, polyester, etc. that can be easily torn and is formed of a directional film. As shown in FIG. It is sealed by the seal portion 11 and has a water-filled portion 12 formed inside thereof.
The notch on the side seal part 11 from the edge toward the water sealing part 12
By providing 13 a part of the seal portion 11 forms a tape piece 14. In addition, a recess 12a is formed in the water enclosing portion 12 such that the distance between the tip of the notch 13 and the water enclosing portion 12 is a predetermined distance L, whereby the periphery 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, the water bag 9 has a cut film
It has a direction along 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 container body 2 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.

A spacer 16 is provided between the inner plate 3 and the bag body 10 to form a plurality of voids 15 extending from the center side of the inner plate 3 to the peripheral edge on the lower surface side of the inner plate 3. The spacer 16 is composed of a plurality of rectangular bar-shaped portions 17 that extend radially in the same plane, and is arranged so as to be positioned at the center of the lower surface of the middle plate 3, so that the space between the adjacent rectangular bar-shaped portions 17 is increased. 15 are formed.

That is, since the inner plate 3 is placed on the bag body 10 via the spacers 16, the lower surface of the inner plate 3 is placed on the spacers 16.
Is separated from the bag body 10 by the thickness dimension thereof, and the space other than the spacer 16 forms the plurality of voids 15 in the space formed by this separation.

The spacer is not limited to the shape like the spacer 16 shown in FIG. 2, but any spacer may be used as long as it forms a space extending from the center side of the inner plate 3 to the peripheral edge thereof under the inner plate 3. It may be one. For example, as shown in FIG. 3, it may be a spacer 18 in which a plurality of rectangular bar-shaped portions 18b are extended from both sides of a linear bar-shaped portion 18a, or a plate-shaped member may be provided with a notch. It may be a spacer in which the void is formed by a notch.

According to the heating and heating container 1 configured as described above, the notch 13 is advanced by pulling the tip of the tape piece 14 to easily break the water sealing portion 12, and the water W enters the bag body 10. Thus, the hydration reaction can be started, and the foodstuff or the like contained can be heated and sufficiently steamed.

That is, as shown by the arrow in FIG. 1, the vapor generated by the hydration reaction passes through the void 15 formed in the upper portion of the bag body 10 by the spacer 16 interposed on the lower surface side of the inner plate 3. Since it is also discharged from the upper surface of the body 10, a large amount of vapor passes through between the side wall of the inner plate 3 and the container body 2 and flows into the inner plate 3.

Further, according to the heating and heating container 1, the size of the void 15 can be changed by changing the dimensions such as the thickness of the spacer 16, and thereby the amount of vapor discharged can be adjusted.

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 one notch 13 may be 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 14 and the opening is not performed, and the opening can be easily performed.

According to the heating and heating container 1 of the present embodiment, a large amount of water vapor due to the hydration reaction can be released and allowed to flow into the inner plate in which the contents are stored. Therefore, there is an effect that the stored item can be sufficiently steamed, and when the stored item is a food such as sushi, the umami of the food can be sufficiently brought out.

Moreover, since the amount of the steam discharged can be adjusted by the size of the spacer 16, there is an effect that the degree of steaming the stored items can be optimized.

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, the spacer may be fixed to the lower surface of the inner plate 3 by adhesion or the like, and may be a ridge formed integrally with the lower surface of the inner plate 3.

Secondly, the heat-generating agent 8 is stored in the bag, but the heat-generating agent 8 may be wrapped inside the aluminum sheet having a small hole by folding the heat-generating agent 8 instead of being stored in a bag of an aluminum sheet. Further, this surface may be covered with a non-woven fabric.

Thirdly, regarding the positional relationship between the water bag and the exothermic agent, the exothermic agent may be disposed on the bottom side of the container on which the water bag is placed,
Further, two water bags may be arranged above and below the exothermic agent.

[Advantage of the Invention] According to the heating and heating container of the present invention, a large amount of water vapor due to the hydration reaction can be released and allowed to flow into the inner plate in which the contents are stored. For this reason, it is possible to steam the entire stored item evenly and sufficiently, and when the stored item is a food product such as sushi, the umami of the food item can be sufficiently brought out.
