Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a simple heating box that can easily heat and cook food and drinks, such as canned coffee, Japanese sake, and retort foods such as curry and stew.

(Prior Art) Integrated food containers have recently come into widespread use, which house canned coffee, retort food, and the like as objects to be heated, together with a heating device, and which are capable of instantly cooking food and drink by activating the heating device and generating heat. There is. However, most of these require the food container to be molded from Styrofoam, plastic, metal foil, etc. to accommodate the heating device, which requires molding processing and is expensive to manufacture due to material costs. . Therefore, the container is subjected to moisture-proofing treatment, and a heating element is placed along the inner circumferential wall or in the center of the container, and the packaged food can be stored in contact with the heating element. A food packaging structure has been proposed in which a certain amount of water is injected to cause a hydration reaction using the water absorbing property of a heating element, and the bag food is heated and cooked using this heating effect (for example, Unexamined Japanese Patent Publication 1986-1977
(See Publication No. 880).

(Problems to be Solved by the Invention) However, since this type of food container uses a box container as the packaging structure, it can be manufactured relatively easily, but only a heating element is placed inside the box container. Since it is contained in a container, it is necessary to pour a certain amount of water into the container when using it. Therefore, it is necessary to always have water on hand, and it is not convenient when carrying it with you on mountain climbing, hiking, etc. Furthermore, the box container needs to have a waterproof structure, and there remains the problem that there is a limit to the reduction in manufacturing costs.

The present invention has been made in view of the above problems, and provides a simple heating box that can easily heat objects to be heated such as food and drinks, is easily portable, and can be manufactured at low cost. The purpose is to

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a water bag having an opening member fixed to one end, a heat generating material case filled with a heat generating material that generates heat through a hydration reaction, It consists of a box-shaped container in which a housing part is formed at the bottom to accommodate a water bag and a heat generating material case,
The box-shaped container is characterized in that a drawer opening is formed on one surface of the box-shaped container to draw out the other end of the opening member outward.

(Function) When the other end of the opening member pulled out of the box-shaped container is pulled, the water bag is opened and the leaked water comes into contact with the heat generating material in the heat generating material case. Heated steam is generated by this hydration reaction of the exothermic material, and this heated steam fills the box-shaped container. Thereby, the object to be heated housed in the box-shaped container is heated.

(Example) Embodiments of the present invention will be described below based on the drawings.

The simple heating box is shown in FIGS. 1 and 3, and houses a heat generating material case 2 filled with a heat generating material 3 and a water bag 4 in a box-shaped container 1, and also stores canned coffee and bottled Japanese sake. It has a structure that can accommodate objects to be heated 5 such as retort foods and packaged foods.

The box-shaped container 1 is a vertically rectangular parallelepiped paper container that is heat resistant and water resistant, and has openings 1a at the top and bottom.

1b is provided. And, on the periphery of the upper and lower openings,
Foldable pieces 6 to 11 for closing each opening are integrally formed. That is, on the upper opening ld side, there are left and right sides 1c, l.
A trapezoidal folding piece 6° 7 is provided on the periphery of d, and a substantially rectangular folding piece 8 is provided on the periphery of the rear surface le. An insertion piece 8a is formed at the tip of this folding piece 8,
When the folding piece 6.7 is folded into the upper opening ld side to close the opening, the insertion piece 8a is inserted along the inner wall 1g side on the front side 1f side, and each folding piece 6 to 8 can be locked. ing. A recess 12 is formed at the center of the periphery on the front surface 1f side to facilitate insertion or withdrawal of the insertion piece 8a. In addition, an adhesive sheet 14 is placed in this recess 12.
is pasted to cover the recess 12 to prevent the insertion piece 8a from being removed and to allow the box-shaped container 1 to be sealed.

On the other hand, on the lower opening 1b side, trapezoidal folding pieces 9 and 10 are also connected to the left and right surfaces 1c and the periphery of the ld side, and a substantially rectangular folding piece 11 is connected to the periphery of the rear 1e side. An insertion piece 11a with a notch 11b in the center is formed at the tip of this folding piece 11, and this insertion piece is inserted along the inner wall 1g on the front lf side as described above, and each fold Pieces 9 to 11 can be locked.

A concave outlet (3) is formed at the center of the periphery on the front surface 1f side, which facilitates the operation of inserting and removing the insertion piece 11a, and also facilitates opening and opening (described later) through the notch 11b and the outlet 13. The member 16 and the peeling member 17 can be pulled out. Further, the adhesive sheet 14 is pasted on the outlet 13 as described above, and the adhesive sheet 14 is attached to the outlet 13 as described above.
This cover prevents the insertion piece 11a from being pulled out, allows the box-shaped container 1 to be hermetically sealed, and also temporarily fastens both members 16 and 17.

The heat-generating material case 2 is a dish-shaped container with an upward opening, stores the heat-generating material 3 therein, covers the opening 2a with a heat-shrinkable film 15, and is placed on the bottom surface 1h of the box-shaped container 1.

The heat generating material case 2 is made of a heat insulating material and prevents direct contact between the heat generating material 3 and the box-shaped container 1, thereby reducing the thermal influence on the box-shaped container l due to the heat generating action of the heat generating material 30. It is possible to reduce this. As the heat generating material 3, granular quicklime [
Calcium oxide (Cab) is used, and a predetermined amount necessary for heating the object to be heated 5 is set in advance.

The heat-shrinkable film 15 is made of polypropylene or the like that shrinks under high heat and does not retain its original shape, and is adhered or heat-sealed to the periphery of the opening surface of the heat-generating material case 2 . One end edge 1 of this heat-shrinkable film 15
One end 16a of a tape-shaped peeling member 16 is fixed to 5a. This peeling member peels off the heat-shrinkable film 15, and its other end 16b is pulled out from the outlet 13 of the spit-type container 1, and the adhesive sheet 1 is attached to the front surface 1f.
It is temporarily attached using 4.

The water bag 4 is formed by stacking sheets made of polypropylene with high heat shrinkability and heat-sealing the periphery. The interior is filled with an amount of water necessary for the exothermic material 3 to cause a hydration reaction and heat the object to be heated 5 to an appropriate temperature.

Further, this water bag 4 is weakened from one end edge 4a to the other end edge 4b, and one end 17a of a tape-shaped opening member 17 is fixed to the back surface of the one end edge 4a side. This unsealing member is used to unseal the water bag 4, and the other end 17b is pulled out of the box-shaped container 1 through the outlet 13, and is temporarily bonded together with the peeling member 16.

Note that instructions for handling the simple heating box 1 and precautions are displayed around or on the front surface lf of this temporary bonding.

The water bag 4 is placed on the upper surface of the heat generating material case 2, and one end edge 4a is fixed to one end edge 2b of the heat generating material case 2 with a stapler 18 or the like with a heat shrinkable film 15 interposed therebetween.

Note that this fixation may be performed by heat sealing. A sheet 19 made of nonwoven fabric is placed on the upper surface of the water bags 4 stacked in this manner, and the object to be heated 5 is placed on the upper surface of this sheet.

Therefore, in the simple heating box configured as above, the water bag 4, heat generating material case 2, etc., and the box-shaped container 1 are separated, and this box-shaped container can be folded and kept flat. .

Therefore, it can be easily stored in a backpack, bag, etc.
Easy to carry. In use, after assembling the box-shaped container 1 as described above and storing the heat generating material case 2 and water bag 4 in the closed lower part, the object to be heated 5 is placed.
is stored in a box-shaped container 1 as shown in FIG. 2, and the upper part is closed and sealed to use the box-shaped container in an upright state.

Next, the heating action of the simple heating box will be explained.

When the unsealing member 16 and peeling member 17 attached to the front surface of the box-shaped container 1 are peeled off in six directions in FIG. The heat-shrinkable film 15 is peeled off. At this time, water leaking from the water bag 4 comes into contact with the exothermic material 3, causing a hydration reaction and generating heated steam G (see FIG. 3). When this heated steam comes into contact with the heat-shrinkable film 15 and the water bag 4, they are thermally shrunk and become smaller. At this time, the object to be heated 5 slightly descends, but is kept stable by the sheet 19 and stands in the center. Therefore, the opening 2a of the heat generating material case 2
Heated steam G rises from the whole and fills the box-shaped container 1 through the sheet 19. Thereby, the object to be heated 5 is easily heated.

(Effects of the Invention) As explained above, the present invention stores a water bag and a heat generating material case in a box-shaped container, and can also store an object to be heated, so that when using the container, simply pull the opening member. can heat the object to be heated. Therefore, there is no need to prepare water during use, and the box-shaped container is easy to carry, making handling extremely simple. Furthermore, box-shaped containers are easy to manufacture and assemble, and a wide range of materials can be selected, which has the effect of further reducing manufacturing costs.
