[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating container that stores food in a steaming container and separates in a lower container to generate heat due to a reaction caused by mixing water and quicklime. The present invention relates to a food heating / steaming device capable of heating and steaming food in a steaming container housed in a container, so that the food can be eaten in a warm state.

[0002]

2. Description of the Related Art As a conventional food heating device, a heat-resistant container, a reaction material that reacts with water or a substance similar to water delivered to the bottom of the container to generate high temperature steam, and What is provided with an inner lid for placing a non-cooked article, which is provided above the reactants and has a vapor permeation hole, and an outer lid which is fitted to the upper end of the container and seals the inside of the container. Are known.

In this food heating device, if the container is turned over to take out the food, the residue of the reaction material mixed with water adheres to the food through the holes and cannot be used for edible food. In addition, cleaning the residue and storing the reactants in a heat-resistant container are troublesome.

Therefore, in Japanese Utility Model Publication No. 5-6916, a heat-resistant base having a heating container accommodating portion on the inside of the leg plate portion and a caustic placing portion on the upper portion, and quicklime are accommodated, and the heating is performed. A water bag holding member housed in a container housing, a water bag placed on the upper part of the water bag holding member and broken by pulling an operation tape, the leg plate portion of the heat resistant bed or the heating bag. A food heating device provided with a heavy material such as an iron plate fixed to a container has been proposed.

[0005]

[Problems to be Solved by the Invention]
In the food heating device described in Japanese Patent No. 16 publication, since the caustic wax is placed on the heat-resistant base plate, a gap is created between the heat-resistant base plate and the caustic wax, and even if there is no gap, the pressure from the bottom does not apply. Seiiro was pushed up into a gap, and steam leaked from this gap, and it was difficult for steam for steaming food to spread sufficiently into Seirou.

[0006] In addition, since the steam that has entered the seiro easily escapes from the gap between the lid and the seiro covered with the seiro, the food in the seiro escapes to the outside without heating and steaming. However, there are problems in that the food cannot be sufficiently heated and steamed, and that much time is spent.

The present invention solves the above-mentioned problems of the conventional food heating device, and allows the steam generated by the reaction of water and quick lime to be sufficiently spread into the food, whereby complete heating and steaming are performed in a short time. The purpose is to eliminate the risk of the reaction residue of water and quicklime contacting food.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, as the heating and steam generating member in the present embodiment, an inner container 1 formed of a watertight material and provided with a collar 1a on the upper surface to form a pot shape
A bag 4 formed of a sealing material such as polyethylene, in which the tearing string 2 is attached, and in which water 3 is stored,
It contains quicklime 5 that reacts with water to generate heat and generate steam.

Then, a metal thin film 6 such as an aluminum foil is placed on the upper surface of the inner container 1, the thread string 2 is led out to the upper surface thereof, and the breathable paper 7 is placed on the metal thin film 6. Then, the metal thin film 6 and the breathable paper 7 are closely adhered to the collar 1a of the inner container 1 to seal the upper surface of the inner container 1.

Between the inner container 1 and the lower container 8, the lower container 8 is made of a heat-insulating molding material such as styrofoam, and is provided with a brim 8a bulging outward at the upper end. Then, the cardboard 9 having water absorbency is interposed and housed, and the string 2 is led out to the outside of the lower container 8.

The inner container 1 is formed of a plastic material on the air-permeable paper 7 and has ventilation holes 1 on the periphery and bottom.
0a is bored, and the steaming container 10 provided with a flange portion 10b bulging outward on the upper end surface is placed,
In this steaming container 10, cooked and semi-dried rice 12 contained in a bag 11 made of polyethylene or the like having a property of blocking the outside air, and cooked side dishes 13 contained in a similar bag 11 are contained.

A concave ring 14b is formed near the lower end of the upper container 14 having a hanging wall 14a at a position overlapping with the collar portion 10b of the steaming container 10, and the concave ring 14b is formed.
The lower side is a conical enlarged surface 14c, and the concave ring 14b is fitted into the collar 8a of the lower container 8 to form the steaming container 1
The upper container 14 and the lower container 8 are locked with 0 stored.

The upper container 14 has an engaging recess 1 near the upper end.
4d, and as shown in FIG. 4, the upper surface as a whole is formed as a mid-height surface, and the engaging convex portion 15b is formed on the peripheral hanging wall of the lid body 15 on which the two handles 15a are formed. The engagement protrusion 15b is engaged with the engagement recess 14d of the upper container 14, and the upper surface of the upper container 14 is covered with the lid body 15.

In this embodiment, the rice 12,
When eating the side dish 13, the upper container 14 can be pulled out upward while the lid 15 is covered by removing the fitting state between the collar 8a of the lower container 8 and the concave ring 14b of the upper container 14. Therefore, the steaming container 10 stored in the upper container 14 can be taken out.

Then, the bag 11 is broken to open the rice 12 into the steaming container 10, the side dish 13 is further spread on the steamed container 12, and the collar 8a of the lower container 8 is fitted into the concave ring 14b of the upper container 14 again to fix them. Return to the state.

When the string 2 is pulled in this state, the bag 4 is broken because the tip of the string 2 is attached to the bag 4, and the water 3 therein mixes with the quicklime 5, and the quicklime 5 becomes water. Reacts with and generates heat, and this heat causes water to rise to steam.

If the string 2 is further pulled from this state, the string 2 enters the quicklime 5 and cuts the metal thin film 6, and the steam generated by the cutting of the metal thin film 6 is cut. Steaming container 1 through the area and the breathable paper 7
Pass through the ventilation hole 10a of 0 and enter the steaming container 10.

At this time, the heat of quicklime is also steamed at the same time as the steam container 1
0, so that the rice 12 and the side dish 13 in the steaming container 10 are warmed and steamed at the same time, and after this warming and steaming are completed, the engaging protrusions 15b of the lid 15 are engaged with the upper container 14. Pull out from the depression 14d and cook with rice 12 and side dishes 13
Is what you eat.

In this embodiment, since the lower container 8 and the upper container 14 can keep the flange 8a and the concave ring 14b tightly fitted,
The steam does not escape from the joint between the lower container 8 and the upper container 14 to the outside, and the upper container 14 and the steaming container 1 are almost in perfect condition.
It is possible to prevent the steam and heat from being wastefully released to the outside.

The volume of the quick lime 5 expands when it reacts with the water 4, so that the metal thin film 6 and the breathable paper 7 are pushed up, and therefore the steaming container 10 is also pushed up, so that the collar portion 10b of the steaming container 10 is lifted. The upper container 14 is brought into contact with the hanging wall 14a, steam is prevented from escaping into the upper container 14 during this period, and the steam container 10 is provided through the side vent holes 10a.
Since it goes inside, the rice 12 and the side dishes 13 can be steamed sufficiently.

In this case, the water droplets generated by the contact of the vapor on the upper surface of the lid body 15 are guided to the middle height of the upper surface of the lid body 15 and move around the lid body 15 to drop into the upper container 14. ,
The drop of taste does not occur due to water drops dripping into the rice 12 or the side dish 13.

The water droplets from the lid body 15 drip in the upper container 14 together with the dew condensation of the vapor in the upper container 14 and flow into the lower container 8. Since the thick paper 9 having water absorbability is interposed, the water droplets dropped in the lower container 8 are absorbed by the thick paper 9 and do not wet the desk even when the lower container 8 is turned on.

Further, since the breathable paper 7 is pasted on the upper surface of the quicklime 5, the residue reacting with the water 4 does not go out of the inner container 1, and the residue causes the lower container 8, the upper container 14, It is possible to prevent the steaming container 10, the rice 12, and the side dish 13 from being contaminated.

Next, an example of a packaging state in which the food heating and steaming apparatus shown in this embodiment is sold will be described with reference to FIGS. The locking plate A formed of cardboard or the like for fixing the three members of the upper container 14, the lower container 8 and the lid 15 has a transverse shape of the lower container 8 at the lower end position of the enlarged surface 14c of the upper container 14 in the center. A fitting hole 20 having the same shape as the surface is formed. Therefore, when the fitting hole 20 is fitted into the lower container 8, the lower container 8 and the upper container 14 are placed on the locking plate A. Becomes

On the outside of the fitting hole 20, the locking plate A is designed such that the rising portion 21 is raised from the rising line 21a, and thus the rising portion 21 is raised. A semicircular notch 22a is formed at a position corresponding to the height of the upper surface of the lid 15 when the notch 22a is opened, and the notch 22a is opened to form an insertion hole 22 at the notch 22a.

Further, the locking plate A is provided with an outer portion 23 outside the notch 22a, that is, by pulling the leading end sides of the left and right rising portions 21 toward the center side so that they overlap each other. A U-shaped cutout 24a is formed at a position on the center side of 23, and the left and right cutouts 24a are tilted inward and overlapped as shown in FIG.

The outer part 23 serves as a handle by stacking and fixing the outer part 23. As a method of stacking and fixing the left and right outer parts 23, fixing with a stapler, sticking with a double-sided adhesive tape, Alternatively, one-sided adhesive tape may be used as a means for winding and fastening.

Next, the chopsticks 25 are inserted so as to pass over the lid 15 from the one insertion hole 22, and the tip of the chopstick 25 is pulled out from the other insertion hole 22 to make the cut 2
2a prevents the chopsticks 25 from falling off due to the elasticity of the chopsticks 25 trying to return to the inside of the insertion hole 22 and the resistance force of the lid 15 pushing up the chopsticks 25.

The chopsticks 25 thus inserted are used as the lid 15.
Is pressed downward, the lid 15 is prevented from coming off from the upper container 14, and the food heating and steaming apparatus has the ring-shaped bulging portion 8a of the lower container 8 and the concave ring 1 of the upper container 14.
It is fixed in the vertical direction by fitting 4b. In this state, if the outer part 23 is unfixed, the chopsticks 25 are easily pulled out from the insertion hole 22, and the fitting hole 20 is pulled out from the lower container 8, The food heating and steaming device can be removed from the plate A.

INDUSTRIAL APPLICABILITY In the present invention, since the conventional food heating device may bring the residue of the reaction between quick lime and water into contact with the food, care should be taken in handling the food so that the food cannot be eaten by these contact. However, the residue does not come into contact with food without special care, and its handling becomes easy.

In the past, since the container containing the food and the container for heating and steaming the food were simply placed, the steam leaked from the place where the food was placed, and the amount of the leak was taken into account to prepare the quicklime. It was necessary to increase the amount of water, but since the lower container containing water and quicklime and the upper container storing food were combined to eliminate the gap, warm the food,
It is enough to store the amount of quicklime required for steaming.

Further, the steam generated and entering between the upper container and the steaming container pushes up the steaming container due to the expansion of the volume due to the reaction between quick lime and water, so that the gap between the steaming container and the upper container is increased. Since it does not escape to the outside due to the contact between the collar part and the hanging wall, enter the inside of the steaming container from the ventilation hole on the side of the steaming container,
The food in it can be steamed sufficiently and quickly to help steam it.

Further, the water droplets formed by the external temperature being transmitted to the steam and condensing are dropped on the inner surface of the upper container and absorbed by the water absorbing material in the lower container, and even when the lower container is turned over, the apparatus for heating and steaming foods. This has the advantage that there is no risk of spilling outside and wetting the desk or the like.
