Description

  The present invention relates to a lunch box structure, and more particularly, to a lunch box structure that is a paper or wooden box that can be fitted and joined.

  The history of the act of serving foods and dishes using bento boxes and serving them for food is very old. Currently, containers used to dispose of food and dishes (hereinafter collectively referred to as lunch boxes) are mainly made of materials such as plastic, paper, and wood chips. Among them, plastic lunch boxes are low in heat resistance and are not desirable from the viewpoint of environmental protection, so evaluation of lunch boxes made of paper or wood pieces has begun to increase.

  In general, a conventional lunch box made of paper or wood pieces is cut on the four sides at the bottom and folded face to face to form four sides. Further, the short two surfaces are sandwiched between the two long surfaces to form a connection relationship between each side and the bottom. Next, using a piece of paper, the adjacent sides are bonded together. Thus, after each side rises, it is supported by the piece of paper and maintains a rectangular box-like structure in which five sides are joined. Furthermore, a lid piece is extended on one side of the box and the upper surface is sealed.

  However, since the conventional lunch box structure made of paper or wood piece is simply formed by adhering a simple cubic development structure with an adhesive, the strength of the structure is insufficient.

  Furthermore, the outline of a simple square box is poor.

  In addition, in a conventional lid piece that extends directly from one side of the box body, when the upper surface is sealed, the one side is supported by the box body, but the opposite side is a free closing edge, so the receiving force becomes unbalanced and the box body The food is easily deformed. In addition, since a rubber band must be fitted and fixed, it is not desirable from the viewpoint of environmental protection, is not deformed and is not beautiful, and the contents to be put in are limited. The present invention has been made in view of the above-described drawbacks of the structure of a conventional lunch box.

The first problem to be solved by the present invention is that the two connecting plates correspond to the side plates that fold up from the two sides of the bottom plate, and are fitted to each other and installed to form the bottom box structure. This is to provide a bento box structure having an optimum strength and a more beautiful appearance by raising a space below the bottom box.
The second problem to be solved by the present invention is that an upper lid is installed above the bottom box, folding edges are installed on both sides of the top lid, and they are fitted to both sides of the bottom box. It is to provide the structure of a special lunch box.

  In order to solve the above problems, the present invention provides the following lunch box structure.

  The present invention is easy to assemble, has high structural reliability, and has a beautiful appearance compared to conventional products.

It is an external appearance structural view of the container for cooking of this invention. It is an exploded view of the upper cover and bottom box of the first embodiment of the present invention. It is an exploded view of the bottom box structure of 1st Example of this invention. 1 is a sectional structural view of a first embodiment of the present invention. It is an exploded view of the bottom box structure of 2nd Example of this invention. It is local sectional drawing of 2nd Example of this invention.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings.

  As shown in FIGS. 1, 2, and 3, the structure of the lunch box of the present invention can be used by selectively making the top lid 20 correspond to the bottom box 10. The bottom box 10 includes a bottom plate 11 and a connecting plate 12.

  The bottom plate 11 is a wooden rectangular plate piece, and side plates 111 that are folded upward and are formed on opposite sides. The outline of the two side plates 111 is approximately trapezoidal, and a fold line 112 is installed between the two side plates 111 and the bottom plate 11.

  The two connecting plates 12 are coupled to correspond to the other opposite side of the bottom plate 11 that is different from the side plate 111. In addition to forming a trapezoidal body corresponding to the side surface of the bottom plate 11, foldable wing pieces 121 are installed on both sides thereof. A fold 122 is installed between the two blade pieces 121 and the connecting plate 12 main body. A projecting piece 123 and a folded plate 124 are formed on the bottom and top of the connecting plate 12, respectively, and these can be folded relatively inward, and between the projecting piece 123 and the folded plate 124, A groove 125 is formed.

  2, 3, and 4, the plate end of the bottom plate 11 is fitted into the groove 125 of the connecting plate 12, and at the same time, the two wing pieces 121 and the two side plates 111 of the bottom plate 11 are bonded to each other. 2 constitutes a bottom box 10 shown below.

  Further, an arcuate engaging portion 126 is formed on the outer edge of the blade piece 121 of the connecting plate 12, whereby the upper lid 20 can be fitted.

  As shown in FIGS. 1, 2, and 4, the upper lid 20 includes a vertex plate 21 that seals the top of the bottom box 10. In addition, folding edges 211 are installed opposite to both sides of the wing piece 121. A fold line 212 is installed in advance between the two folded side 211 main bodies and the rectangular apex plate 21 main body, and engaging portions 213 corresponding to the wing pieces 121 are installed on both side edges of the folded side 211, respectively. To do.

  When the bottom box 10 is assembled, first, the side plates 111 on both sides of the bottom plate 11 are raised upward as shown in FIGS. Next, the two connecting plates 12 wrap the two sides of the bottom plate 11, and the wing pieces 121 of the two connecting plates 12 are bonded to the outside of the two side plates 111 of the bottom plate 11. In this way, a bottom box 10 structure is formed that projects obliquely outward from the bottom. As shown in FIGS. 2 and 4, the upper lid 20 seals the upper side of the bottom box 10, and the engaging portion 213 of the folding side 211 and the wing piece 121 are engaged with each other, and the structure of the lunch box shown in FIG. 1. Form.

  In the second embodiment of the present invention, side plates 111 and 113 are formed on all opposing sides of the bottom plate 11 as shown in FIG. That is, the folded plate 124 shown in FIG. 3 is replaced by the side plate 113 facing the position of the connecting plate 12. In the connecting plate 12 of the embodiment shown in FIG. 5, only the protruding piece 123 is installed below, and the bottom plate 11 is directly supported above the protruding piece 123. Further, as shown in FIGS. 5 and 6, the bottom of the bottom plate 11 is in contact with the upper side of the protruding piece 123, and the side plate 113 of the bottom plate 11 and the connecting plate 12 are bonded with an adhesive to increase the strength.

Therefore, the use of the present invention has the following advantages.
1． Since the bottom box 10 and the bottom plate 11 and the connecting plate 12 correspond to each other in different ways and are combined, the assembling is easy, the reliability of the structure is high, and the appearance is beautiful compared to the conventional products.
2． Since the bottom plate 11 of the bottom box 10 is higher than the connecting plate 12, an isolated space can be formed between the table or the table and the effect of keeping dishes warm can be exhibited.
3． Although the top lid 20 and the bottom box 10 are separated from each other, the fitting is very easy, and the top lid 21 can directly shield the opening of the bottom box 10 by the top lid 21 of the top lid 20. Are folded into the two side plates 111 of the bottom box 10 to be engaged with the engaging portions 126 of the two connecting plates 12, so that the top lid 20 and the bottom box 10 are firmly joined. In addition, the close contact effect between the top lid 20 and the bottom box 10 can be improved.

  The above description and illustrations are only the optimum embodiments of the present invention, and are used only for explaining the technical contents of the present invention, and do not limit the present invention. All structures, devices, features, approximations and similarities of the present invention shall be included in the protection scope of the present invention.
