Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a lunch jar.

(Prior Art) A lunch jar is a thermos flask made of stainless steel with a vacuum double structure that houses a soup bowl, a rice bowl, and a 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 lunch jars 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. ing.

(Problem to be solved by the invention) In such a vertical lunch jar, because the thermos flask has a narrow mouth, the inner container such as a rice bowl has a narrow mouth and a deep bottom structure, making it difficult to use a regular lunch box. It does not have a wide mouth like a box, making it difficult to eat.

Therefore, if you install the thermos horizontally so that the mouth opens to the side, and insert the rice bowl with the lid upwards into the thermos from the side, the rice bowl will open at the mouth of the thermos. It is possible to secure an opening that is as wide as the width and depth of the thermos, making it easier to eat, and the thermos itself has a narrow opening and is deep, so it retains heat without compromising its insulation properties. Sexuality improves.

However, with this horizontal launcher,
Since the thermos flask has a narrow mouth, there is a problem in that it is difficult to insert and remove the inner container such as a rice bowl.

The present invention was devised in view of such problems, and an object of the present invention is to provide a lunch jar in which it is easy to insert and remove inner containers such as rice bowls.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a lunch jar in which a medium container is inserted from the side into a horizontally placed medium bottle, and a medium stopper is provided to cover the mouth of the medium bottle. The medium container is detachably connected to the medium container, and the medium container can be taken in and out of the medium bottle by holding the medium stopper.

(Example) Next, an example of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a launcher according to the present invention,
It roughly consists of a main body 1, a medium bottle 2, a lid 3, a rice bowl 4 as a medium container, a medium stopper 5, and a vegetable container 6.

The main body 1 is a rectangular container that opens upwardly and laterally, and the upper opening is covered with a partition plate 7 fitted.
As shown in FIG. 2, the edge of the side opening is formed with an annular groove 8 into which the tip of a mouth 9 of a medium bottle 2, which will be described later, is fitted. Further, as shown in FIG. 3, the height of the front edge of the main body 1 is lower than the height of the rear edge.

The medium bottle 2 is a container made of stainless steel with a vacuum double structure and having a rectangular cross section, and is housed and fixed in the main body 1 in a horizontal manner so that its mouth 9 opens laterally. That is, this medium bottle 2 is stored in the main body 1 before the partition plate 7 is fitted, and when the partition plate 7 is fitted into the main body 1, the protruding piece 10 provided at the end of the partition plate 7 is inserted into the main body. As a result of fitting into the gap between the bottom of the bottle 1 and the bottom of the medium bottle 2, it moves to the right in FIG. has been done.

Further, 11 is a chip tube used to exhaust air and vacuum seal it during the manufacture of this vacuum double-structure medium bottle 2, and is provided at the lower part of the outer surface of the medium bottle 2.
It is covered with a cap 12. This chip tube 1

Elastic protrusions 22, 22 are protruded into two at the tips of the elastic protrusions 22, 21, and claw parts 2 are provided at the tips of the elastic protrusions 22, 22.
Step portions 24, 24 are formed at 3, 23 and the base. On the other hand, two parallel protrusions 25, 25 are protruded from both sides of the button mounting hole 19, and engagement grooves 26, 26 are formed at both ends of each protrusion 25, 25.

When the push button 20 inserts its elastic protrusions 22, 22 between the protrusions 25, 25, the claws 23, 23 at the tips engage the engagement grooves 26, 26, and at the same time, the stepped portions 24, 24 open. Engagement groove 2
6 and 26, and is fixed to the lid body 3. Moreover, this push button 20 has a button mounting hole 19 due to the elasticity of the elastic arms 21, 21.
The inner surface thereof is substantially flush with the inner surface of the lid 3, and faces the pressing portion 27 at the tip of the elastic piece 16 of the partition plate 7 when the lid 3 is closed.

As shown in FIG. 2, the rice bowl 4 is a container that can be inserted into the medium bottle 2 from the side with the lid facing up. The lid 28 has a recess 2 that can accommodate a spoon, etc.
9 is formed. As shown in FIG. 3, the cross section of the rice bowl 4 is approximately rectangular with rounded corners along the inner surface of the medium bottle 2, so the lid 28 is separated at a position that avoids these corners. I'm starting to do that. Therefore, the lid 28 inherently has a space, and this space is effectively utilized to accommodate the spoon accommodation recess 29.
was formed.

The inner stopper 5 has a cover 32 forcibly fitted to a stopper main body 31 filled with a heat insulating material 30, and has a shape that can be fitted into the mouth portion 9 of the inner bottle 2. In the outer circumferential groove 33 provided on the outer circumferential surface of the stopper body 31 of the inner stopper 5, there is a seal gasket 34 that comes into pressure contact with the inner surface of the inner bottle 2.
is installed. In addition, the inner stopper 5 can be attached to and detached from the rice bowl 4 by engaging the engaging parts 35 and 36 formed on the stopper body 31 with the receiving parts 37 and 38 provided on the side surface of the rice bowl 4. possible to be connected. A lever-shaped knob 39 is rotatably attached to the cover 32 of the inner stopper 5 by 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. ing.

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, It is adapted to be accommodated in a container accommodating section 14. Further, when the vegetable container 6 is placed on the partition plate 7, a recess 4 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.
2 is formed. In other words, if the concave portion 42 of the vegetable container 6 and the convex portion 13a of the partition plate 7 are not in a position to fit together, the vegetable container 6 will not be placed in the vegetable container storage portion 14.
It is regulated so that it cannot be accommodated.

A pickle accommodating section 43 for accommodating pickles and the like is formed on the inner surface corresponding to the recess 42. A pickle storage portion 4 is provided on the inner surface of the lid 41 so that the pickle storage portion 43 is sealed when the lid 41 is closed.
A rib 41a that contacts the opening edge of No. 3 is provided in a protruding manner. As shown in FIG. 2, when the lid 41 is correctly attached, a rib 44 horizontally protruding from the outer surface near the opening edge of the vegetable container 6 and a rib 45 protruding from the edge of the lid 41 are formed. The ribs 44 and 45 are regulated so that they do not interfere with each other, and that the ribs 44 and 45 interfere with each other if the lid 41 is installed in the opposite direction.

In the launcher having the above configuration, the mouth part 9
A medium bottle 2 is horizontally installed in the main body 1 so that it opens to the side, and a rice bowl 4 with a lid 28 facing upward is inserted into the medium bottle 2 from the side to accommodate it. Therefore, the rice bowl 4 has the width of the mouth 9 of the medium bottle, and the width of the medium bottle 2.
A relatively wide opening with a length equal to the depth of the container can be secured, and the depth can be made shallow accordingly, resulting in a container that is easy to eat and has good usability.
As a result of the rice bowl 4 becoming narrow, long, and shallow in this way, the medium bottle 2 that houses it has a narrow mouth 9 and a deep bottle, so that the heat 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 rice bowl 4 is removably connected to the inner stopper 5, even if the mouth part 9 of the inner bottle 2 is narrow,
The rice container 4 can be surely inserted deep into the medium bottle 2 by holding the knob 39 of the medium stopper 5. Even when taking out the rice bowl 4, the rice bowl 4 can be easily pulled out at the same time by simply holding the knob 39 and removing the inner stopper 5. If the inner stopper 5 is removed, it will not get in the way when eating.

When the lid 3 is closed, the tip of the knob 39 of the inner stopper 5 fits inside the lid 3, allowing the main body 1 to be tilted,
Since the inner stopper 5 will not come off even if it is shaken, the rice bowl 4 is safe because there is no risk of it flying out when being carried or dropped.

On the other hand, the vegetable container 6 is housed on the outside of the medium bottle 2, that is, in the vegetable container accommodating section 14 formed by the partition plate 7 and the lid 3, so that the heat of the rice container 4 is not transferred to the vegetables inside. will not be corrupted.

Note that the medium bottle 2 is not limited to a rice bowl, but may also contain a soup bowl or a simple container without a lid for storing solids. In the case of a medium container for storing solids, the mouth does not necessarily have to face upward, but may face forward or backward; in short, it is sufficient to have the mouth in a direction perpendicular to the opening of the medium bottle 2.

Further, in the above embodiment, the rice bowl 4 and the inner stopper 5 are detachably connected, but as shown in FIG. The rice bowl 4 may be placed on this tray 51.

(Effect of the invention) As is clear from the above explanation, according to the invention, the rice bowl is removably connected to the inner stopper, so it can be inserted into the medium bottle by holding the inner stopper, or removed from the medium bottle. It has the effect of being easy to put in and take out.
