Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an instant food heater. That is,
A heater provided inside a container for cooking and packaging instant food, the heater for instant food having a function of heating the food in the container by utilizing the heat generated by the hydration reaction of quicklime, etc. Is.

[Prior Art] Conventionally, it has been performed to loosen an instant food or the like by utilizing an exothermic reaction of hydration of quicklime or the like. In this case, at the time of heating, the water bag is broken and the water discharged from the bag comes into contact with the hydration reaction agent to cause a reaction.

Conventionally, as a method of letting water flow out from this water bag, for example, place a food container on a water bag that has a cut on the side of the bag as shown in FIG. A method of stripping off half is used.

However, in this method, if the bag is cut and a film that is easy to tear is used as the material, the bag is easy to tear. There is a risk of spillage and heat generation, and on the contrary, making it strong requires strong force,
There is a risk of spilling food because your hands are crazy,
Further, when tearing the bag, there is a drawback that the tear stops halfway and water does not come out.

[Problems to be Solved by the Invention] The present invention provides a simple food heater having a water bag that can be safely transported and handled and has a structure that allows water to reliably flow out with a small force. The purpose is to do.

[Means for Solving Problems] The inventors of the present invention have made earnest studies on a method of draining water by a method of not making the cuts 24 in the water bag as shown in FIG. 4, and as a result, the tape attached with an adhesive. When peeling off the tape, fold the tape back from the adhesive line and pull it in the direction in which the adhesive tape is attached as shown in Fig. 5. The point where the tape can be easily peeled off with a small force, and the adhesive tape is solid unless it is pulled. Focusing on the fact that the adhesive tape adheres to the film, the present invention has been accomplished by the structure in which the holes provided in the water bag are closed by this adhesive tape.

That is, the present invention relates to an instant food heater having a mechanism in which the hydration reaction agent 1 and the water bag 2 are housed in the heat generating portion 10 and the water bag 2 is broken to react with water and the hydration reaction agent 1 to generate heat. A hole 3 is provided on the surface of the water bag 2, and an adhesive tape 4 is put on the hole 3,
The pulling tape 5 is attached to one end of the adhesive tape 4, and the pulling tape 5 is brought into contact with the adhesive tape 4 and folded back.
Furthermore, the present invention provides a heater for instant foods, characterized in that the tip 6 of the pulling tape 5 is placed outside the heat generating portion 10 and installed.

The present invention will be described in more detail with reference to the drawings of the embodiments.

The water bag 2 made of plastic film shown in FIGS. 1 and 2 has a hole 3 formed on the surface of the water bag 2, and an adhesive tab 4 is attached to the surface film with an adhesive, which covers the hole 3. I'm out.

In this embodiment, the holes 3 are arranged in a line on the surface of the water bag 2.
I opened two. If the diameter of this hole is increased and the number of holes is increased, water will flow out at once when the adhesive tape is peeled off. On the contrary, if the diameter of the holes is small and the number of holes is small, the outflow rate of water becomes small and the degree of heating can be controlled. In the present invention, since the diameter of the hole can be made as small as possible, the heating rate can be freely controlled depending on the food.

The hole 3 of the water bag 2 of this embodiment is covered with an adhesive tape 4.

Since this adhesive tape 4 is firmly adhered to the film surface of the water bag 2 with an adhesive, it does not come off even when handling is unsuccessful such as vibration or dropping during transportation, so that unexpected heat generation does not occur. Absent.

The water bag of this embodiment is manufactured by injecting a certain amount of water from another inlet to an adhesive tape 4 attached to the hole of the bag in advance and sealing the inlet by heat fusion. You can

In this embodiment, a pull-out tape 5 is attached to the tip 9 of the adhesive tape 4 as shown in FIG. 2, the width of the tape is narrower than that of the adhesive tape 4, and no adhesive is applied to this.

In this embodiment, the pull-out tape 5 is bent at a folding line 9 in the drawing, which is attached back to back with the adhesive tape 4.

In this embodiment, the hydration reagent 1 is used in a form in which the hydration reagent is wrapped in a metal film having a large number of holes, and the water flowing out from the water bag 2 enters through the holes and hydrates. Reacts with Reactant 1 to generate heat. In this case, due to this heat generation, the water flowing out of the water bag 2 is heated to become steam, and the steam steams the food.

As the hydration reaction agent, any substance that generates heat due to a hydration reaction such as quick lime can be used as long as it is not toxic. For example, a commercially available hydration exothermic agent under the trade name Ozomax Ozo Kagaku Giken) and the like can be particularly preferably used.

In the present embodiment, the bag of the hydration reaction agent 1 is installed under the water bag 2, but it can be placed on the water bag 2.
Further, in each case, the heating condition can be changed by making the surface of the water bag 2 having the holes upward or downward.

In this embodiment, the adhesive tape 4 and the pull-out tape 5 are combined back-to-back and installed in the heating section 10 as shown in FIG. 1, and the tip 6 of the pull-out tape 5 is taken out of the heating section 10 and this tip is taken out. 6 is fixed to the side surface of the food container with an adhesive.

When the connecting portion 9 of the adhesive tape 4 and the pull-out tape 5 attached to the water bag 2 of this embodiment has a gently widened tip as shown in FIG. 2, the pull-out tape 5 can be pulled with a small force. Although the connecting portion 9 is easily peeled off, it is somewhat easily peeled off due to a large impact or the like. On the other hand, adhesive tape 4
When the angle from the connection portion 9 is rapidly widened, a large force is required to peel off the tip of the connection tape 4, but it is very safe against impact or the like.

In the present invention, the shape of the connecting portion can be selected appropriately according to the application and the way of handling food.

In the present invention, the pull-out tape 5 is pulled, and once the tip of the adhesive tape 4 is peeled off, the adhesive tape 4 can be peeled off with a very small force thereafter. This is because the pull-out tape 5 is pulled in the opposite direction from the point where it is adhered, and therefore the peeling-off portion receives a force of several tens of times the pull-out force by the lever principle.

In this embodiment, the pull-out tape 5 is pulled out from the hole 7, but the hole 7 has a width narrower than the width of the adhesive tape 4. Therefore, the adhesive tape 4 is caught on the side wall of the heater and does not go out. If the hole 3 is pulled out as described above, it is possible to confirm that the hole 3 is completely opened, and there is an advantage that the unnecessary tape is not pulled out and troubled in its cleaning.

[Effects of the Invention] The instant food heater of the present invention is characterized by the structure of the water bag that is housed therein, and because this structure firmly blocks the outflow hole, a water bag can be used during handling such as transportation and impact. It is safe because it will not be damaged, and has the advantage that water can be easily discharged with a weak force when using it. Furthermore, by selecting the number and diameter of the water holes 3, the conventional method can be used. The advantage of being able to greatly control the situation of heat generation, which was not possible with, for example, it can be designed so that rice can be cooked, and it is very advantageous for heating instant foods and foods, for which demand will increase in the future.
