Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a disposable non-leakage type lunch box case.

[0002]

[Prior art]

 Conventionally, as shown in FIGS. 1 to 3, a rectangular box-shaped side wall 11, 11, 12, 12 is used as a lunch box case with a partition to prevent different kinds of side dishes and rice from contacting and mixing with each other. A rectangular bottom plate 16 is stretched over the frame 15, and a thin plastic plate is press-molded in a box-shaped body 10 having a shallow bottom, which is made of wood or plastic. The one in which the plate-shaped body 20 which is divided into a plurality of partitions by vertically arranging the partition 23 is fitted is used. In addition, 24 is a bead standing upright on the periphery of the dish 20.

However, in the above-mentioned conventional lunch case, the bottom plate 16 is attached to the frame body 15 and the bottom surface 25 of the plate-like body 20 so that liquid such as sauce and soy sauce does not leak from the box-shaped frame 10 when eating the lunch box. At the same time, it is necessary to have a double bottom, which raises the problem that the manufacturing cost of the bento case increases accordingly.

[0004]

[Problems to be solved by the device]

 The problem to be solved is that in the above-mentioned conventional lunch case, the bottom plate 16 is attached to the frame body 15 to prevent the liquid such as sauce and soy sauce from leaking from the box-shaped frame 10 when eating the lunch box. It is necessary to make a double bottom together with the bottom surface 25 of the above, which increases the manufacturing cost of the lunch case.

[0005]

[Means for Solving the Problems]

 This will be described with reference to FIGS. 1 and 3 to 7. A first invention is a rectangular frame body 15 formed by bending and joining four rectangular plate-shaped side walls 11, 11, 12, 12 and a frame body 15 fitted and installed in the frame body 15 15 has a bottom surface 25 having substantially the same shape as that of the plastic plate-shaped body 20 of a roller, and the downward direction of the fastening portion K formed by bending the peripheral edge portion of the plate-shaped body 20 downward into an L shape or an L shape. The adhesive C is applied to the outside of the surface, and the fastening portion K applied with the adhesive C is inserted into the horizontal groove M formed at the inner surface of the frame 15 and at a height close to the lower end. It is glued to the bottom.

The second invention is a lunch box case in which a partition is provided so as to prevent different kinds of side dishes and rice from contacting and mixing with each other and divided into a plurality of compartments. A rectangular frame body 15 made of wood or plastic formed by bending and joining 12 and 12, and the frame body 15 which is fitted and installed in the frame body 15 and is formed by press molding a plastic thin plate. It is composed of a dish-shaped body 20 in which vertical and horizontal partitions 23 are integrally erected vertically and horizontally on a bottom surface 25 of substantially the same shape, and the peripheral edge portion of the dish-shaped body 20 is bent downward to form a letter or L shape. The adhesive C is applied to the outside of the downward surface of the fastening portion K, and the fastening portion K coated with the adhesive C is formed into a horizontal groove M formed on the inner surface of the frame 15 and at a height close to the lower end. Inserted and glued to the bottom of the groove M Is.

【Example】

 An embodiment of the bento case of the present invention will be described as follows. In other words, 15 is a rectangular frame body formed by joining four rectangular plate-shaped side walls 11, 11, 12, 12 made of wood or plastic to the joint end surface 13, and the height is close to the inner surface and the lower end. Further, a horizontal groove M is formed. Reference numeral 20 denotes a dish-like body that is fitted and installed in the frame body 15 and divides the upper surface into a plurality of compartments. A plastic thin plate is press-molded to form a bottom surface 25 having the same shape as the frame body 15 and a bottom surface 25. The partition 23 is vertically and horizontally integrated, and the peripheral edge of the plate-shaped body 20 is bent downward into an L-shape or a L-shape to form a fastening portion K. A low bead 24 is formed along the peripheral edge of the dish 20. Moreover, the upper surface of the plate-shaped body 20 may be divided into a plurality of sections by the beads 24 instead of the partition.

When the dish-shaped body 20 is fitted into the frame 15 and attached, the adhesive C is applied to the outside of the downward surface of the fastening portion K, and the fastening portion coated with the adhesive C is applied. K is inserted into the groove M of the frame body 15 and adhered to the bottom of the groove M.

To explain the operation, by doing so, the adhesive C rotates not only on the outer surface of the fastening portion K but also on the inner surface thereof, and the outer surface of the downward portion of the fastening portion K is not only the inner surface of the groove M, Since the inner surface is also strongly adhered to the lower surface of the groove M, the frame 15 and the dish 20 are watertightly sealed, and the bottom plate stretched on the lower side of the frame 15 is also erected on the peripheral edge of the dish 20. Even if there is no side wall, liquid such as sauce, soy sauce, etc., which is put on the side of the dish 20 when it is eaten, does not leak from between the frame 15 and the dish 20 when eating the bento.

[0010]

[Effect of device]

 Since the present invention is configured as described above, the frame body 15 and the dish-shaped body 20 are watertightly sealed, and the bottom plate stretched under the frame body 15 can be omitted, resulting in a large production cost. It can be reduced. Of course, when eating the bento, the liquid such as sauce or soy sauce that has flowed out onto the upper surface of the dish 20 does not leak from between the frame 15 and the dish 20.
