Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a latch shear.

(Prior Art) A latch shear is a thermos flask made of stainless steel with a vacuum double structure that houses a soup bowl, rice bowl, and vegetable container to keep them warm. It is known that the lid that covers the mouth of a thermos flask has poorer insulation properties than the main body, which has a vacuum double structure, so the narrower the mouth and deeper the bottom, the better the heat retention.

For this reason, conventional latch shears have a structure in which a thermos flask is installed vertically so that the mouth opens upward, and inner containers such as a soup bowl, rice bowl, vegetable container, etc. are stacked one after another in the thermos flask. It has become.

(Problem to be solved by the invention) However, because the thermos flask has a narrow mouth, the mouth of the middle container such as a rice bowl is narrow and has a deep bottom, rather than a wide mouth like a normal lunch box. However, there were problems in that it was difficult to eat and difficult to use.

In addition, since rice bowls and vegetable containers with different insulating temperatures are stacked one on top of the other, it is possible to prevent ffi' by placing heat insulating material at the top of the rice bowl or at the bottom of the vegetable container, for example. It was necessary to provide a heat insulating section between the vegetable container 5 and the vegetable container to prevent the vegetables, etc. in the vegetable container from rotting. For this reason, there was a problem in that the space for accommodating the thermos flask was narrowed by the amount of insulation.

The present invention has been made in view of these problems.Firstly, it provides a latch shear that can accommodate a wide-mouthed and easy-to-use medium container, and secondly, it separately accommodates a rice bowl and a vegetable container. The purpose is to provide a latch shear that can.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the first invention is such that a thermos flask is installed horizontally so that the spout opens laterally, and the mouth of the thermos flask is opened in a direction perpendicular to the opening. This is a container that contains a medium container. Further, a second invention is the latch shear according to the first invention, in which a housing section for housing the vegetable container is provided outside the thermos flask.

A lever-shaped knob 39 is rotatably attached to the cover 32 of the inner stopper 5 via a hinge pin 40. As shown in FIG. 4, the tip of this knob 39 protrudes upward and fits inside the lid 3 so that the rice bowl 4 cannot be pulled out together with the inner stopper 5 when the lid 3 is closed. It has become.

As shown in FIG. 2, the vegetable container 6 is a substantially rectangular container with a lid 41 that can be opened and closed upwards, and is placed on the partition plate 7 of the main body 1, and when the lid 3 is closed, 4 accommodation units! It is designed to be accommodated in 4. Further, when the vegetable container 6 is placed on the partition plate 7, a recess 42h is provided at the bottom corner of the vegetable container 6 so as not to interfere with the convex portion 13a forming the recess 13 of the partition plate 7. (In other words, the vegetable container 6 cannot be accommodated in the vegetable container 4 accommodating portion 14 unless the recess 42 of the vegetable container 6 and the convex portion 13a of the partition plate 7 fit together. regulated.

A pickle accommodating section 43 for accommodating pickles and the like is formed on the inner surface corresponding to the recess 42.

A rib 41a is provided on the inner surface of the lid 41 so as to be in contact with the opening edge of the pickle storage section 43 so that the pickle storage section 43 is sealed when the lid 41 is closed. As shown in FIG. 2, when the lid 41 is correctly attached, a rib 44 protruding horizontally from the outer surface near the opening edge of the main body 6 and a rib 45 protruding from the edge of the lid 41 are removed. Don't interfere! If 4.1 is installed in reverse, the ribs 44 and 45 are regulated so as to interfere with each other.

In the latch shear having the above configuration, the medium bottle 2 is horizontally installed in the main body so that the mouth part 9 opens laterally, and the medium bottle 2
The rice bowl 4 with the lid 28 facing upward is inserted from the side to accommodate the rice bowl. Therefore, the rice bowl 4 can have a relatively wide opening that is as wide as the mouth 9 of the medium bottle and as long as the depth of the medium bottle 2, and accordingly the depth can be made shallow. This makes the container easy to eat and easy to use. As a result of the rice bowl 4 becoming narrow, long and shallow in this way, the medium bottle 2 that accommodates it becomes a bottle with a narrow mouth 9 and a deep depth.
The insulation properties are not impaired. Moreover, since the mouth part 9 is covered with the inner stopper 5 containing the heat insulating material 30, heat retention is further improved.

In addition, since the tip tube 2+ of the medium bottle 2 protrudes into the vegetable container accommodating part 14, which is provided on the side of the bottle and has plenty of space, there is no wasted space in the main body l, as in the case where it is provided at the bottom of the bottle. This does not occur, and the main body 1 can be made smaller.
