Abstract

PURPOSE: To package a lunch container smoothly without hindrance by chopsticks and the like kept out of the way of the package and make it less apt for the containers to get unstable when stacked, by providing a container main body or the side of a cover with a storage part into which eating utensils can be inserted. CONSTITUTION: A lunch container includes a watertight inner container 1, a container main body 2 for storing the inner container 1, and a cover 3 which is placed over it. A storage part 5 into which eating utensils such as chopsticks or spoon can be inserted is provided by making an opening 16 through which they are put in and taken out, a U-shaped cut which is long widthwise, into the peripheral wall 15 of the container main body 2. Additionally, displacement of rubber band put around the container is prevented by providing the container main body 2 and/or the cover 3 with a lock recess 7 for locking the rubber band holding the container main body and cover 3 together. Further, all the way round the edges 8 of the cover 3, recesses and projections which are like waves in the direction of its lengths are formed to prevent a hand from being cut with the edges of the cover.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lunch box container sold at a station shop, a convenience store or the like, and more particularly to an improvement of a paper box container.

[0002]

2. Description of the Related Art Recently, there are various types of bento boxes having different shapes, structures and designs. There are various shapes, structures, and designs of bento containers that are commonly called ekiben. There were various materials such as styrofoam, plastic, and paper. The paper lunch container has various advantages such as light weight, low cost, no pollution even if it is discarded after use, and easy disposal. Therefore, it was suitable for recycling. Since a paper lunch container has a difficulty in watertightness, normally, as shown in FIG. 9, a watertight vinyl chloride inner container B is put in a paper container A, and rice is placed in the inner container B. A side dish is put in to prevent water from leaking from the side dish.

[0003]

No matter what shape or structure the conventional lunch container has, there is no place for accommodating chopsticks, spoons, forks and the like (hereinafter referred to as chopsticks). I sometimes forget to put on chopsticks. In addition, even if chopsticks are attached, there is no suitable place for attachment, so generally, it is put on the lid C and stuck with cellophane tape, or it is put on the lid C without sticking and wrapped from above. The reality is that they are covered with paper and wrapped. However, in that case, there is a problem that the wrapping paper protrudes upward only for chopsticks, and the bento becomes unstable when the lunches are stacked, and the wrapping paper is easily broken. Further, even when the lunch box is automatically packed by the packing machine, since the chopsticks must be placed on the lid C one by one, there is a problem that it is difficult to completely automate (unmanned) the packing.

Further, in the conventional lunch box made of paper, rubber bands are put on the container body and the lid C covering the container body in a plow shape, but there is a position where the rubber band is positioned on both the container body and the lid C. Since there is no rubber band, it is difficult to hang the rubber band, or the rubber band is displaced so that the container body and the lid C are easily separated from each other.

Furthermore, since the outer peripheral edge D of the lid C in the paper lunch container has a sharp edge which is still cut, sliding the hand along the outer peripheral edge D when stopping with the rubber band causes the outside of the lid. Sometimes the hand was cut at the edge D.

An object of the present invention is to provide a lunch box container into which chopsticks can be inserted and attached, a rubber band can be easily applied, the position of the applied rubber band is unlikely to be displaced, and the outer edge of the lid does not easily cut the hand. Especially.

[0007]

A lunch box container according to claim 1 of the present invention comprises a paper container body 2 for containing food and a lid 3 for covering the container body 2 as shown in FIG. In this lunch box, a chopsticks accommodating portion 5 into which chopsticks 4 such as chopsticks and spoons can be inserted is provided on the side surface of the container body 2 or the lid 3.

As shown in FIG. 1, the lunch box container according to the third aspect of the present invention includes a rubber band 6 for fixing the container body 2 and the lid 3 to both or one of the container body 2 and the lid 3. A locking recess 7 that can be stopped is provided.

According to a fourth aspect of the present invention, as shown in FIG. 1, the outer peripheral edge portion 8 of the lid 3 is formed in a wavy concavo-convex shape in its longitudinal direction as shown in FIG.

[0011]

In the lunch container according to the first aspect of the present invention, since the chopsticks accommodating portion 5 into which the chopsticks 4 such as chopsticks and spoons can be inserted is provided on the side surface of the container body 2 or the lid 3, the accommodating portion is the same. It can be stored by simply inserting chopsticks in 5, and the chopsticks 4 hardly project outside the container.

According to a second aspect of the present invention, there is provided a lunch box container comprising:
Since the watertight inner container 1 is housed in the container body 2, the juice of the food contained in the inner container 1 or the sauce applied to the food will not leak.

The lunch container according to claim 3 of the present invention comprises:
Since the locking recess 7 capable of locking the rubber band 6 is provided on either or both of the container body 2 and the lid 3, the rubber band 6 is easily locked in the locking recess 7. It is difficult for the rubber band 6 to be displaced.

In the container for bento according to claim 4 of the present invention,
Since the outer peripheral edge portion 8 of the lid 3 is formed in a wavy uneven shape in the longitudinal direction, even if the hand is slid along the outer peripheral edge portion 8, the hand is not cut.
