Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a food box, and more particularly, to a lunch box having a partition structure.

[0002]

[Prior art]

 Conventional lunch boxes are generally made of plastic or paper and are provided with ribs that partition the interior of the box to form several receiving slots. This has led to the development of more sophisticated and practical methods of making lunch boxes that serve different dishes in different locations and respond to market demands. Making a regular plastic lunch box is easy, but its appearance is usually a single color, so it does not change much and cannot attract the attention of consumers, so it stimulates the consumer's willingness to buy. You can't. Also, the surface of some plastic lunch boxes has patterns to beautify its appearance, but the molded plastic lunch boxes have a three-dimensional structure in a three-dimensional space. When fabricating the pattern by the printing method, it is very difficult to manufacture the pattern, and when the pattern is pasted on the lunch box by the method of pasting the pattern, the dropout often occurs, and these processing methods greatly increase the cost. It is not economically viable. Therefore, plastic lunch boxes are usually confined to one-piece as well as single-color manufacturing methods. Also, plastic lunch boxes are made thinner to reduce costs, so the overall structure is not very strong, it is difficult to hold, and the insulation function is not very good.

[0003] In order to solve the above-mentioned problem, a lunch box manufacturer manufactures a lunch box using paper. The lunch box can be pre-printed on the table before folding the paper, so that the original pattern will be completely preserved when going through processing steps such as cutting, folding and folding. Can be maintained. However, since the lunch box made of paper is made of such a material, only a simple partition can be formed inside the box. For example, as shown in FIG. 4 and 5 are installed, respectively, and they are stuck on the bottom inside the box body 1 to form receiving slots 6 of various volumes, and foods are stored separately.

[0004]

[Problems to be solved by the invention]

 However, since each of the ribs 2, 3, 4, and 5 is attached to the bottom inside the box main body 1, processing time is long. Also, the juice in the lunch box often seeps out from the bonding points of the ribs 2, 3, 4, and 5, and the ribs 2, 3, 4, and 5 made by folding the paper are effective on the bottom inside the box body 1. This lunch box is not applicable to packing a wide variety of dishes because complicated partitions cannot be made. If you want to put a sauce or sauce in the lunch box, the ribs 2, 3, 4, and 5 cannot be effectively partitioned to form an appropriate receiving slot. 7 must be used. As mentioned above, the use of a lunch box made of this paper is very inconvenient, and it seems that some places need to be improved.

[0005] Therefore, a main object of the present invention is to provide a lunch box which can effectively partition the inside of a box body made of paper and form a suitable receiving slot quickly. Another object of the present invention is to provide a lunch box with a small gap between ribs attached to the box body.

Another object of the present invention is to provide a lunch box which can form a complicated and varied receiving slot. Still another object of the present invention is to provide a lunch box having a clever appearance and easy to manufacture.

[0007]

[Means for Solving the Problems]

 A lunch box according to the present invention that solves the above-mentioned problems includes a box body and a partition member, and the partition member is fixed inside the box body, and partitions the inside of the box body into a predetermined number of receiving slots. . The box body is formed by cutting paper, folding lines, folding, and sealing. At least one slot is formed in the bottom of the box, and portions along both edges of the slot are each folded upward to form an adhesive piece. The partition member is made by integrally molding a plastic material, and is provided with at least one rib, the rib having two opposing partition pieces, and a connection surface provided on one side of the partition piece. The connection surface is attached and fixed to an adhesive piece.

[0008]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 2, 3 and 4, a lunch box 100 according to one embodiment of the present invention is a combination of a box body 10 and a partition member 20. The box body is cut into paper, folded, folded, sealed, and then formed into a rectangular container with an open top. The box body 10 has a box bottom 11 and a formed side wall 12 which is folded upward around the box bottom 11. Before folding the box body 10, a dotted line (not shown) for the partition which is cut in advance is provided on the box bottom 11 and a part of the side wall 12. After the dotted line is cut, an open slot 13 is formed on the box bottom 11 and the side wall 12 via the dotted line by folding the paper board between the dotted line and the folding line A upward. The folded paper board is folded upward along both edges of the slot 13 to form an adhesive piece 14.

The partition member 20 is fixed in the box main body 10, and a plurality of ribs 21 connected to each other are formed by integrally molding a plastic material such as PP or PE which can be disassembled. The inside of the box body 10 is partitioned to form a predetermined number of receiving slots 30. Further, the ribs 21 are provided with partitioning pieces 212 and 213 extending downward on both sides of the top surface 211, respectively, and the partitioning pieces 212 and 213 are installed so as to be inclined relative to each other. It is narrower upward and wider downward. Connection surfaces 212a and 213a are provided on the inner surfaces of the partitioning pieces 212 and 213, and the connection surfaces 212a and 213a are bonded to the outside of the bonding piece 14 of the box body 10 (see FIG. 4). Are folded outward to form folds 214, and when the partition member 20 is adhered to the box body 10, each fold 214 can be mutually bonded to the adhesive on the side wall 12.

The above is a description of each member, structure, and related positions of the lunch box according to one embodiment of the present invention. The lunch box 100 is manufactured by appropriately cutting a paper board, folding a line, folding, and sealing and processing, and then manufacturing a box body having a rectangular container shape. A slot 13 and an adhesive piece 14 are formed thereon. The partition member 20, which is manufactured by integrally molding plastic, affixes the connection surfaces 212a, 213a inside the partition pieces 212, 213 to the outside of the adhesive piece 14, respectively. Fix it. If the inside of the box body 10 is divided by the partition member 20 having a plurality of ribs 21 and a predetermined number of receiving slots 30 are formed, food can be separated and received.

In this embodiment, the box body 10 made of paper is used for receiving food. The face of the box body 10 made of the paper material can be provided with a variety of skillful decorative patterns, attracting the attention of consumers, and meeting the demands of the market. The disadvantage that it is difficult to provide a decoration such as an integrally formed lunch box can be improved. Further, in this embodiment, the partition member 20 made of plastic which is easy to mold is fixed in the box main body 10, thereby dividing the inside of the box main body 10 into a required number of receiving slots 30. The disadvantage that it is difficult to partition a conventional lunch box made entirely of paper can be improved. In addition, since the partition member 20 having an integral and complicated section can be molded by using a plastic molding method, only one bonding process is required, and the production speed is greatly increased. The ribs are made by integral molding and there are no gaps between the ribs, which is an unattainable point of a traditional paper lunch box. Therefore, the lunch box 100 of the present embodiment can be partitioned into a predetermined number of receiving slots 30 in addition to having an aesthetic surface, and can be processed and manufactured quickly, and further, the gap of the lunch box can be reduced. Box 100 is likely to be a popular product.

FIG. 5 shows another embodiment of the present invention. In this embodiment, the bottom edges of the partition pieces 212 and 213 provided so as to equally divide the partition member 20 are provided with hem 212b and 213b extending horizontally outward. , 213b are flatly attached to the inner surface of the box bottom 11, so that the adhesive strength between the partition member 20 and the box body 10 can be enhanced.

FIG. 6 shows still another embodiment of the present invention. In this embodiment, the partition member 20 is manufactured by integrally molding plastic, and the receiving portions 215 having different depths are formed integrally between the adjacent ribs 21 at the same time when the partition member 20 is manufactured. The receiving portion 215 is capable of receiving sauce, sauce or other food. Further, the height of the ribs 21 of the partition member 20 can be changed variously to meet various demands. As shown in FIG. 6, some ribs 21 have the same height as the top surface of the box body and are parallel to the top surface of the box body. When being stacked, the ribs 21 are used as supports to prevent food from being pressed and deformed. The complex changes in partitioning described above are not achievable with traditional paper lunch boxes.
