Description

A stainless steel lunch box having a partition plate for preventing inflow of side dish soup stocks {Lunch box}

The present invention relates to a lunch box container made of a stainless steel material. In particular, it is divided into a rice container and a side dish so that it can be easily cleaned while being cleaned, and the soup produced in a side dish is introduced into a compartment .

Typically, the lunch box container is made up of a container for storing rice and side dishes, and a lid for sealing. Most of these container cases are made of a plastic material or a metal material.

Most of these lunch box containers are made up of various types of containers so that the containers can contain the rice and side dishes separately, or the containers can contain both rice and side dishes at the same time.

However, when the lunch box container is formed separately for the rice and the side dish, since the volume of the package is increased, there are various inconveniences such as the inconvenience of carrying and washing dishes for washing after use. There is a lot of lunch box containers that can serve rice and side dishes at the same time.

Therefore, the container of the lunch box container used as one needs a partition for storing the rice and the side dishes. In order to form such a partition, most of the lunch boxes are made of plastic by injection molding.

However, when the container body is made of plastic, the rice and the side dishes put in the container body are contained in a hot state in order to provide warmth. In this case, there is a problem that environmental hormones such as harmful substances harmful to the human body are generated.

Therefore, a lunch box container made of a stainless steel material which is durable and capable of holding hot rice or a side dish harmless is most preferable. However, such a stainless steel lunch box container has a complicated and difficult process for forming a partition integrally .

Registration Practice 20-0296742 (November 20, 2002)

Accordingly, in order to solve such a problem, the present invention uses a container made of a stainless steel material so that a partition plate can be detachably installed in such a container so that rice and side dishes can be contained at the same time, will be.

For this purpose, a protrusion protruding downward from the bottom surface is formed inside the accommodation space by a draw-in process on a part of the bottom surface of the container housing, so that the partition plate, which is in the form of a plate in the receiving space, is partitioned by closely fitting to the protrusion, So as not to enter the accommodated space.

Further, it is also possible to form a grasping boss on the upper surface of the protrusion so that the partition plate fits into the grasping biceps to be in a more stable upright state, and the auxiliary protrusions are formed on the inner surface of the container housing with the protrusions, So that the partition plate does not flow and can maintain a more stable upright state.

Further, the rim of the partition plate is provided with a packing member made of rubber or silicone to completely seal the gap.

Therefore, according to the present invention, since the partition plate is provided in the container housing of the stainless steel material which is strong and durable even with the hot rice and the side dish, the rice and the side dish are not mixed with each other and the soup produced in the side dish does not flow into the rice, So that the packaged state is maintained.

Further, since the partition plate is provided to be detachable, the lunch box container used can be easily cleaned and can be used hygienically.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the present invention includes a stainless steel container 10 having an upper opening to accommodate rice and side dishes, and a lid for sealing to the opened upper end of the container 10 20 are coupled to each other or a coupling frame 10b made of a plastic material is provided at the upper end of the container enclosure 10 so that the lid 20 is hermetically engaged by the locking means 21, A protruding portion 13 protruding toward the inside of the accommodation space 11 is formed in the housing space 12 and a partition plate 30 for partitioning the accommodation space 11 is formed in the housing space 11 in which the protrusion 13 is formed ) Are detachably coupled.

As shown in FIGS. 3 to 6, the container housing 10 is manufactured by a drawing method. As shown in FIGS. 3 to 6, the accommodation space 11 is gradually widened toward the upper end and a curved surface 11a is formed at the upper end And the protruding portion 13 formed on the bottom surface 12 is formed to be lower in height from the bottom surface to the inside of the accommodation space 11 by drawing processing, The partition plates 30 are brought into close contact with the projections 13 to divide the accommodation space 11 so that the rice and the side dishes are divided and contained in the accommodation space 11 by the partition plate 30, This prevents the rice from flowing into the compartment containing the compartment. As the compartment plate 30 is detached, it is possible to facilitate washing such as washing dishes after eating the lunch box, and thus hygienic use becomes possible.

The lower end of the partition plate 30 is brought into close contact with the protrusion 13 or the upper surface of the protrusion 13 so that the partition plate 30 can be stably upright in the receiving space 11 of the container housing 10. [ The ribs 14 are formed so that the partition plate 30 is seated on the ratchet 14 so as to partition a space in which the rice and the side dishes are stored.

And is formed by drawing a center of the plate from the outer bottom of the container housing 10 in a state where a thin plate is positioned on the bottom surface 12 of the accommodation space 11 for forming the above-

The auxiliary protrusions 15 are formed on both sides of the inner surface of the container enclosure 10 so as to be spaced apart from each other by the thickness of the protrusion 13 formed on the bottom surface 12 and the thickness of the partition plate 30, Is inserted into the accommodation space 11, or is in a more stable upright state while being detachable.

The auxiliary protrusions 15 may be formed as a pair so as to have a spacing distance to the left and right sides of the partition plate 30 by a thickness of the partition plate 30 so that when the partition plate 30 is inserted into or removed from the accommodation space 11, The partition plate 30 is guided between the first and second partition plates 15 so as to be easily inserted and removed.

On the other hand, a plastic outer container 10a is integrally formed on the outer side of the container enclosure 10 by double injection molding to provide various designs of the lunch container.

A space is formed between the container housing 10 and the inner container 10a so that the inner container 10a to which the container housing 10 is coupled can be kept warm in the rice and the side dishes contained in the accommodation space 11, To provide warm food of lunch box containers.

In order to minimize the area of the receiving space 11, the partition plate 30 is formed to have a thin thickness and a handle portion formed to be round and curled so as to be easily detachable is formed at the upper portion. The handle portion is formed with a partition plate 30 having a small thickness, So that it is reinforced without being bent.

A packing body 31 made of a rubber or silicon material is provided on the edge of the partition plate 30 so that the wall surface and the bottom surface 12 of the accommodation space 10 of the container housing 10, It is completely sealed so as not to generate a gap in the rib 14, and the side dish does not flow.
