Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a portable food container equipped with a heating function.

``Prior Art'' This type of container has a cavity (heating tank) containing quicklime and a water bag at the bottom of the container body, and when necessary, the water bag is destroyed by an external operation such as a pin. It is known that water is applied to the quicklime to generate heat, and this heat is used to warm food such as alcoholic beverages inside the container.

``Problems to be Solved by the Invention'' However, in the conventional container described above, most of its constituent members were press-formed products made of aluminum alloy, which has high thermal conductivity.

As a result, the container itself is also heated when the heat is generated due to the above-mentioned sedation effect, making handling very troublesome as it is too hot to hold directly in the hand.

Therefore, an object of the present invention is to provide a container containing food that is convenient to handle while maintaining a good heating function by molding some of the constituent members of the container from a suitable synthetic resin material.

"Means for Solving the Problems" In order to solve the above-mentioned problems, the container of the present invention has a bottomed metal cylindrical body with a space 8 between the body 6 and the inner surface of the lower part of the resin cylindrical body 6. a container body 1 with a fixed container 7;
A metal can 2 containing food for heating, which is fitted into the container body with a gap 9 formed between it and the inner wall surface of the container body, and water for reaction, which is filled into the lower half of the gap 9. metal oxide A and into the upper half of the space 9,
Both the inner and outer cylinders 12a and 12b that stand up from the inner and outer peripheral edges of the flanged bottom wall 11 are fitted together, and a second A small space 15 is formed, and the second small space bottom wall 11b is positioned below the first space bottom wall 11a to make the second small space deeper than the first space,
A water container 3 in which the first space is filled with water B and the upper surface of the first space is closed with a sealing material 16, and the metal can is detachable and has an outer peripheral portion fixed to the upper end of the body of the container. and a cone 5 housed in the second small space and having a length that allows the sealing material and the bottom wall of the first space to be opened by pressing down from above the water container. Configured.

"Action" For example, from the state shown in Figure 1, move the cone 5 to the second small space 1.
5, and then push down (pierce) the awl from above the water container 3, aiming into the first space 13.

As a result, the bottom wall 11a of the first space is opened, and the water B in the first space flows into the lower half of the spacer 9 and acts on the metal oxide A such as quicklime.

As a result, the metal can 2 is heated by the heat generated by the above-mentioned sedation effect, and food such as alcoholic beverages inside the metal can 2 is warmed. At this time, the metal can 2, such as aluminum alloy, which serves as the heating element, has high thermal conductivity and increases the temperature well, but the body 6 of the container body, which is held by hand, is made of a resin material with low thermal conductivity, so it does not increase the temperature. Does not increase temperature.

``Example'' An example of the present invention will be described below based on the accompanying drawings.

As shown in FIGS. 1 and 2, the food container according to the present invention includes a container body 1, a metal can 2 containing food for heating, a metal oxide A for water reaction, and a water container. 3, and a presser plate 4 for preventing metal cans from being pulled out.
and the cone 5 are the main members.

The container body 1 is made by reinforcing at least the inner surface of the lower half of a resin body 6 with a metal wall 7a. In the illustrated example, a flange-bottomed cylinder 7 made of metal (steel, etc.) is placed in the lower half of a body 6 made of resin (polypropylene, etc.), and the cylinder wall 7a has a slight circumference 〓8.
The container main body is formed by having a raised bottom shape and being fitted at the bottom wall portion 7b.

The metal can 2 is fitted into the container body 1 with a gap 9 formed between it and the inner wall surface of the container body 1. In the illustrated example, an aluminum can whose mouth (see broken line in the figure) is fully opened by a pull ring 10 is used. Further, as the food for heating, liquids such as alcoholic beverages and fluids such as stew are suitable.

The metal oxide A is filled into the lower half of the space 9. In the illustrated example, calcium oxide (quicklime) is filled.

The water container 3 has both inner and outer cylinders 1 that stand up from both the inner and outer peripheries of the flanged bottom wall 11 into the upper half of the space 9.
2a and 12b are fitted together, and two partition plates 1 are installed vertically in a part of the first space 13 formed between these two cylinders.
A second small space 15 is formed between 4a and 14b, and the second small space bottom wall 11b is positioned below the first space bottom wall 11a to make the second small space 15 deeper than the first space 13. water B in the first space 13.
It is made of resin (polyethylene, etc.) and is filled with a seal material 16 and the upper surface of the first space is closed with a sealing material 16.

In the illustrated example, two second small spaces 15, 15 are formed at point-symmetrical positions in the first space 13, and the first space 13 is divided into two. Further, as the sealing material 16, a ring-shaped aluminum seal is used.
Furthermore, an inward flange 17 is provided at the upper end of the inner cylinder 12a.
a, and an outward flange 1 at the upper end of the outer cylinder 12b.
7b, the inward flange 17a engages with the mouth of the metal can 2, and the outward flange 17b engages with the upper end of the container main body body 6.

The presser plate 4 is made of resin and has an outer peripheral portion fixed to the upper end of the container body body 6. In the illustrated example, the outer peripheral portion is the above-mentioned outward flange 17b.
It is also fastened to the upper end of the body of the container. Further, from the inner peripheral edge of the presser plate 4, a fitting cylinder portion 18 is provided.
is being erected. Furthermore, the holding plate 4 has through holes 1 at symmetrical positions above the first spaces 13, 13 and symmetrical positions above the second small spaces 15, 15, respectively.
9... is drilled.

The cone 5 has a length that allows the sealing material 16 and the bottom wall 11a of the first space 13 to be opened by pressing down from above the water container 3, and is made of resin stored in the second small space 15. It is made by In the illustrated example,
Two cones 5,
5 are vertically provided, and these awls 5, 5 are housed in the second small spaces 15, 15 by penetrating the through holes 19, 19 of the presser plate 4 so as to be freely insertable and removable.

Therefore, this embodiment has the advantage that the two cones 5, 5 can be operated simultaneously by the ring-shaped plate portion 20.

"Effects of the Invention" As explained above, according to the present invention, the metal bottomed cylinder 7 is fixed to the lower inner surface of the resin cylindrical body 6 with a gap 8 between the body 6 and the container body 1. consists of
In addition, a gap 9 was formed between the inner wall surface of the container body and the metal can 2 containing food for heating was fitted therein, and the lower part of the gap 9 was filled with a water-reactive metal oxide A. Therefore, the heat generated by the metal oxide directly heats the metal can 2 with high thermal conductivity, and also heats the metal can 2 even when it is transmitted through the metal bottomed cylinder 7, thereby achieving good heating. .

On the other hand, the metal bottomed cylindrical body 7 is fixed to the resin cylindrical body 6 with a gap 8, so that the gap 8 serves as a heat insulating layer, and the cylindrical body 6 is made of resin with low thermal conductivity. Coupled with this, the cylindrical body 6 to be held by hand can be maintained at a low temperature, making handling extremely convenient. In addition, in this invention, the food for heating is packed in a metal can in advance, so
There is an advantage that the metal can containing the food can be used for both heating and non-heating purposes.
