Description

  The present invention relates to a bento container for packaging lunch boxes, side dishes, and the like sold at supermarkets and convenience stores.

Conventionally, a bento container is a container body for storing bento food, a lid that can cover the opening of the container body in a sealed state, and an outer peripheral part of the bottom surface of the container body when stacked on the upper outer periphery of the lid Is formed of a protrusion-like load-unloading ring that prevents unloading by entering, and at least a pair of adhesive tapes that fix the container body and the lid at opposing portions.

When the container body and the lid are fixed with at least a pair of adhesive tapes, the adhesive tape is attached so as to pass over the load-displacement prevention ring of the lid.
For this reason, when the adhesive tape is positioned in an inclined state on the inner side of the load slip prevention ring and stacked, there is a drawback that it is easy to move along the inclined surface of the adhesive tape, and the load slip is easy to occur.
nothing special

    In view of the conventional drawbacks as described above, the present invention can be reliably engaged with the load preventing ring without obstructing the adhesive tape for fixing the container body and the lid when stacked. It aims at providing the lunch container which can prevent.

    Another object of the present invention is to provide a lunch container using an adhesive tape that can reliably determine the state when the adhesive tape that fixes the container body and the lid is tampered with and removed. The purpose is that.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention.

In order to achieve the above object, the present invention provides a container main body in which a bento food is stored, a lid that can cover the opening of the container main body in a sealed state, and a stack formed on the upper outer periphery of the lid. In the lunch container comprising a protrusion-shaped load-dissipation prevention ring that enters the outer periphery of the container main body and prevents load-displacement, at least one opposing portion of the load-disengagement-prevention ring is formed on a flat surface, and the flat surface If the container body is illegally removed at the end, the lunch box is fixed with adhesive tape having at least one notch formed in the length direction so that a part of the end remains. Consists of a container.

  As is clear from the above description, the present invention has the following effects.

(1) At least one portion of the load prevention ring is formed on a flat surface, and the flat surface and the container body are fixed with an adhesive tape. By fixing with an adhesive tape on the flat surface of the ring, it is possible to prevent the adhesive tape from becoming an inclined surface and causing load loss as before, and to make the load prevention ring function for its original purpose. be able to.

(2) According to the above (1), since the structure is simple, it can be easily implemented.

(3) According to the above (1), the direction of the lunch box to be transferred by a belt conveyor or the like can be reliably set by forming a flat surface at one portion facing each other.

(4) When the adhesive tape is illegally removed by the above (1), the adhesive tape is cut so that a part of the end of the adhesive tape remains by the notch formed at the end of the adhesive tape.
For this reason, it can be confirmed that it has been removed illegally by leaving a part of the end of the adhesive tape.

  Hereinafter, the present invention will be described in detail with reference to the best mode for carrying out the invention shown in the drawings.

  In the best mode for carrying out the present invention shown in FIG. 1 to FIG. 9, reference numeral 1 is a lunch container of the present invention, and this lunch container 1 is opposed to one end of an opening in which lunch food 2 is stored. A rectangular container body 5 having an angled section-shaped lid fitting piece 4 having arcuate flange portions 3 and 3 projecting outward at the center of the portion to be formed, and the lid fitting piece of the container body 5 A lid 7 made of a transparent material having a fitting portion 6 formed on an outer peripheral portion to be fitted and fixed to 4 and a flat upper surface; and a bottom outer peripheral portion of the container body 5 formed on the outer peripheral portion of the lid 7. The projecting load preventing ring 9 having flat surfaces 8, 8 formed at the central portion of the arcuate flanges 3 and 3, the lid 7 and the container body 5 are inserted into the lid 7. The adhesive tapes 10 and 10 are fixed to the flat surfaces 8 and 8.

  As shown in FIG. 7, the adhesive tapes 10 and 10 are printed 11 so that the central portion is colored in a strip shape, and the end portions are formed with notches 12 and 12 formed in the length direction. Yes.

Since the lunch container 1 having the above structure is fixed to the container body 5 by the adhesive tapes 10 and 10 at the flat surfaces 8 and 8 of the lid 7, when stacked, as shown in FIG. The lower part of the container main body 5 is securely stored therein, so that the load does not slip.
If the adhesive tapes 10 and 10 are illegally removed, the end portions 10a of the adhesive tapes 10 and 10 are partially cut by the notches 12 and 12 at the ends of the adhesive tapes 10 and 10, as shown in FIG. Since it is cut so that 10a remains, it can be visually confirmed that the adhesive tapes 10 and 10 have been removed illegally.
[Different forms for carrying out the invention]

  Next, different modes for carrying out the present invention shown in FIGS. 10 to 21 will be described. In the description of these different modes for carrying out the present invention, the same components as those in the best mode for carrying out the present invention are designated by the same reference numerals and redundant description is omitted. To do.

  The second embodiment for carrying out the present invention shown in FIG. 10 to FIG. 12 differs from the best first embodiment for carrying out the present invention in that it protrudes from the outer peripheral portion of the bottom surface of the container body 5A. The container main body 5A formed in this way in that the ring ring 13 is formed and the flat surfaces 14 and 14 are formed in the protruding ring 13 portion corresponding to the flat surface 8 and 8 forming portion of the lid 7. Even with the lunch box 1A constructed using the above, the same effect as the first preferred embodiment for carrying out the present invention can be obtained, and both ends of the adhesive tapes 10 and 10 are connected to the lid 7 and the container body. It can be adhered and fixed securely by being adhered to the flat surfaces 8 and 14 of 5A.
