Description

[Detailed explanation of the invention] (a) Field of the invention This invention relates to a thermal lunch box that stores rice utensils, etc. inside the main body.

(b) Background of the invention Conventionally, insulated lunch boxes have been known in which a soup bowl, a rice bowl, a water bottle, a vegetable container, etc. are stacked one on top of the other in the main body. The rice bowl is larger than a soup bowl or water bottle, but the amount of cooked rice varies depending on the person, and especially when only a small amount of cooked rice is stored, extra space is created in the rice bowl.

(c) Purpose of the invention This invention was created by focusing on the extra space created at the top of a rice bowl, and it is possible to fill this extra space with a relatively small sealed container for storing high-temperature liquids, such as a soup bowl or water bottle. The purpose is to make it possible to store the rice in an efficient manner, to make effective use of space, and to prevent heat loss from cooked rice.

(d) Structure of the invention In order to achieve the above object, the invention includes a partition member made of a bottomed cylinder having a flange at the top, which is removably placed on the inner surface step part of the rice bowl by the flange. The interior of the rice bowl is partitioned into upper and lower chambers, a sealed container for storing high temperature liquid is housed in the upper chamber, and a lid member is attached to the open end of the rice bowl.

(E) Description of the embodiment In FIGS. 1 to 3, a metal vacuum double container 2 having a substantially oval cross section is housed inside a resin main body 1, and a spoon is attached to the bottom of the main body 1. A drawer container 3 containing 4 is removably provided.

A rice bowl 5 having an oval cross section is housed inside the vacuum double container 2, and a partition member 6 made of a bottomed cylinder is installed in a stepped portion 5a provided on the inner surface of the upper end of the rice bowl. The rice bowl 5 is placed by the upper flange 6a.
It is divided into two rooms, upper and lower. The lower chamber accommodates cooked rice, and the upper chamber accommodates a water bottle 7 containing boiling water or the like.

A vegetable container 8, which is an example of a lid member, is placed in the upper opening of the rice bowl 5, and is connected to the rice bowl 5 by a fitting 9. That is, a concave groove 5b is provided on the outer periphery of the upper end of the rice bowl 5 approximately halfway around the circumference.
A recessed groove 8a is provided approximately halfway around the outer circumference of the lower end of the vegetable container 8, and upper and lower ribs 9a, 9b of a fixture 9 having a U-shaped cross section are slidably engaged with these recessed grooves 5b, 8a from the side. , the rice bowl 5 and the vegetable container 8 are connected. A heat insulating layer 10 loaded with a heat insulating material is provided on the lower surface of the vegetable container 8 to prevent heat from the rice bowl and water bottle from being transmitted to the side dishes in the vegetable container 8.

A shoulder body 11 is fixed to the upper end of the main body 1, and a lid body 12 is detachably attached to the upper part of the shoulder body 11. Further, a hanging string attachment part 13 is provided on the outer circumferential surface of the upper end of the main body 1, and the hanging cord 1 is attached to this attachment part.
Both ends of 4 are fastened.

As mentioned above, the rice bowl 5 and the vegetable container 8 are attached to the mounting bracket 9.
Since the rice bowl 5 is connected vertically by the holder 8, the rice bowl 5 can be taken out from the main body 1 by lifting the vegetable container 8, and the rice bowl 5 can be removed by pulling out the fitting 9 from the grooves 5b and 8a. It can be easily separated from the vegetable container 8.

Moreover, if the amount of cooked rice in the rice bowl 5 is small, there is a risk that the cooked rice will cool down quickly, but since the water bottle 7 filled with boiling water is housed in the partition member 6, heat dissipation from the cooked rice can be prevented. This results in better heat retention. Furthermore, if the partition member 6 and water bottle 7 are removed from the rice bowl 5, the internal capacity of the rice bowl 5 is almost doubled, and a large amount of cooked rice can be accommodated.

FIG. 4 shows a second embodiment of the present invention, in which a partition member 6 is placed on the upper step 5a of an oval rice bowl 5, a soup bowl 15 is housed in this partition member 6, and the rice bowl 5 A recessed groove 5b is provided approximately halfway around the outer surface of the upper end, and the engaging piece 18 of the inner lid 16, which is a lid member having a heat insulating layer 17, is slidably engaged with the recessed groove 5b from the side. 16 is attached to the rice bowl 5. A peripheral wall 19 is protruded from the upper surface of the inner lid 16, a groove 20 is formed around half the circumference of the peripheral wall, and an engagement hole 21 is formed on the opposite side of the groove.
The vegetable container 8 is attached to the upper surface of the inner lid 16 by engaging the L-shaped projecting piece 22 protruding from the lower surface with the engagement hole 21 and engaging the L-shaped projecting wall 23 with the groove 20. It will be done.

Also in the case of this embodiment, the rice bowl 5, the inner lid 16, and the vegetable container 8 are connected vertically, and by lifting the vegetable container 8, the rice bowl 5 and the inner lid 16 can be taken out from the main body as one unit. can.

In both of the above embodiments, the cover members 8 and 16 are attached to the upper end of the oval rice bowl 5 by slidingly engaging them from the sides, but when the rice bowl is cylindrical, The lid member may be screwed together.

(f) Effects of the invention As described above, according to the invention, a partition member made of a bottomed cylinder is removably placed on the inner step of the rice bowl using a flange provided at the top, so that the inside of the rice bowl can be opened. Since the upper and lower chambers are partitioned, when storing a small amount of cooked rice, the rice can only be stored in the lower chamber, and the upper chamber can be used to store high-temperature liquid storage containers such as soup vessels and water bottles. The space formed can be used effectively and the partition member can be removed to accommodate a large amount of cooked rice. Therefore, the rice bowl can be used in two ways depending on the amount of cooked rice, which is very convenient. Further, when the amount of cooked rice is small, the high temperature liquid storage sealed container is located above the cooked rice, so that heat loss of the cooked rice can be prevented.
