Description

  The present invention relates to a folding container, and more particularly to a folding container suitable for containing food.

  As one of the environmental protection movements, so-called eco-bags are spreading. By repeatedly using bags brought by consumers without using shopping bags at retail stores, the company aims to reduce waste and reduce greenhouse gases. The Applicant is working on a similar environmental protection campaign for food packaging containers. When carrying food, we put it in an assembly container (folding container) and carry it. By repeatedly using this container, we aim to reduce waste and reduce greenhouse gases.

  The ideal of such a container is that it can be folded and carried compactly, a structure that does not spill liquid during use, a material that can be washed and used repeatedly, a container and a lid that are integrated, a container like a cake box It also satisfies many conditions, such as being able to put food in and out from the side of the.

  The take-out paper container disclosed in the cited document 1 can be folded and stored before use, can be easily assembled at the time of use, and has a structure in which oil and water derived from the contents hardly leak from the four corners of the paper container.

  However, the container and the lid are separate, and the container and the lid must be assembled separately. Moreover, since the tongue piece is adhered when the container is assembled, it is difficult to fold it again after use. Moreover, food cannot be taken in and out from the side of the container after the container is assembled.

Therefore, when carrying food, put it in an assembly container (folding container), carry it, and use this container repeatedly to reduce waste and reduce greenhouse gases. Not a container.
Further, the food container disclosed in the cited document 2 is not bulky when not in use, does not leak when used, is easy to assemble and disassemble, can be reused, and provides a hygienic food container. . At the time of assembly, the pair of corner plate portions 6 are externally covered with the cover plate portion 7 and the cover plate portion 7 is locked (from the summary of the cited document 2). Thus, the locking portion is formed by a pair of corner plate portions 6 that overlap the end plate portion 4.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The folding container of the present embodiment is assembled from one resin sheet shown in FIG. In this embodiment, the material of the sheet is polypropylene. In FIG. 1, a solid line other than the solid line indicating the outer periphery of the sheet indicates a mountain fold, and a dotted line indicates a valley fold. FIG. 1 shows a surface that becomes the outside of the container when the container is assembled. When this sheet is assembled along a mountain fold and a valley fold, the container is finally shown in the image of FIG. 12 and the perspective view of FIG. This container is a container with a lid.

  Returning to FIG. 1, the configuration of the sheet will be described. A rectangular bottom member 1 is disposed at the center of the sheet. Square side members 2 to 5 having the same width as the respective sides are connected to the four sides of the rectangular bottom member 1 without a gap. The height of each side member 2-5 is the same. Between the adjacent side members 2 and 3, 3 and 4, 4 and 5, 5 and 2, the folding margin members 6 to 9 that fold up the adjacent side members in the vertical direction from the bottom surface are adjacent to each other. It is connected to the corners of the side member and the bottom member 1 without a gap.

  The substantially rectangular lid members 11 and 12 having the same width as the respective sides are connected to the outer sides of the longitudinal side members 3 and 5 without gaps. Ear members 11a and 11b for closing both sides of the lid when the lid is closed are connected to both sides of one lid member 11 without any gap. Similarly, ear members 12a and 12b for closing both sides of the lid when the lid is closed are connected to both sides of the other lid member 12 without a gap. In addition, a slit-like insertion port 11c is formed in one lid member 11 which is lower when the lid members are stacked, and a tongue 12c is cut in the other lid member 12 which is upper. By hooking a tongue 12c formed on the other lid member 12 to an insertion port 11c formed on one lid member 11, the closed lids are connected and fixed.

  Further, fixing members 13 and 14 for fixing the folding margin members 6 to 9 to the side surfaces are connected to the outer sides of the short side surface side members 2 and 4, respectively. The fixing members 13 and 14 are cut into velos 13a and 14a for fixing the fixing members 13 and 14 to the outer surfaces of the side members 2 and 4, respectively. On the other hand, the side members 2 and 4 are provided with insertion ports 2a and 4a (first locking portions) for hooking the tongues 13a and 14a formed on the fixing members 13 and 14, respectively.

  Here, the insertion ports 2 a and 4 a provided in the side members 2 and 4 are not formed by cutting the side members 2 and 4. A ribbon-like member 15 made of resin is placed on the outer surface of the side members 2 and 4, both ends in the longitudinal direction of the ribbon are welded to the side members 2 and 4, and the ribbon-like member 15 is stretched along the longitudinal direction of the ribbon. The insertion ports 2a and 4a are formed in the.

  The fixing members 13 and 14 are cut into insertion ports 13b and 14b (second locking portions) for fixing the ear members 12a and 12b on both sides of the lid member 12. The tongue members 12a and 12b on both sides of the lid member 12 are formed with tongues 121 to be inserted into the insertion ports 13b and 14b formed in the fixing members 13 and 14, respectively. Each insertion port described above is arranged at a position suitable for inserting each tongue.

  Next, the process of assembling the container from this sheet will be described with reference to the drawings. First, as shown in FIG. 2, food is placed on the center of the sheet, that is, on the bottom member 1. Here, since FIG. 2 shows the inside of the container, the surface opposite to the outside of the container shown in FIG. 1 is shown. From this state, as shown in FIG. 3, the folding margin members 6 to 9 are folded so that the outside is a mountain, and folded so as to overlap the outer surfaces of the side members 2 and 4 to which the fixing members 13 and 14 are connected (see FIG. 3). Middle (1) arrow). Further, the fixing members 13 and 14 are folded back so as to overlap the outer surfaces of the side members 2 and 4, and the folding margin members 6 to 9 are sandwiched between the outer surfaces of the side members 2 and 4 and the fixing members 13 and 14 (in the drawing). (Arrow of (2)). Then, the tongues 13 a and 14 a formed on the fixing members 13 and 14 are hooked on the insertion ports 2 a and 4 a provided on the side members 2 and 4. As a result, as shown in FIG. 4, the four side members 2 to 5 are raised and fixed vertically from the bottom surface.

  Subsequently, as shown in FIG. 5, the two lid members 11 and 12 are stacked so that one lid member 11 is on the bottom and the other lid member 12 is on the top, and folded so as to close the top of the container. The tongue 12c formed on the other lid member 12 is hooked on the insertion port 11c formed on the one lid member 11. Thereby, the lid is closed and fixed.

  Further, as shown in FIG. 6, the ear members 11a, 11b, 12a and 12b on both sides of the lid members 11 and 12 are bent along the side members 2 and 4 and formed into the ear members 12a and 12b where the overlap is on the upper side. By inserting the resulting tongue 121 into the insertion ports 13b, 14b formed in the fixing members 13, 14, the sides of the lid are also closed and fixed.

  However, the image of FIG. 8 shows a type in which the tongue 121 is hooked on the insertion ports 13b and 14b. The structure in which the lid is locked to the fixing members 13 and 14 may be a structure in which the tongue 121 is inserted into the insertion openings 13b and 14b, or a structure in which the tongue 121 is hooked on the insertion openings 13b and 14b. Thus, as shown in FIG. 7, the assembly of the container is completed.

  When the locks on both sides of the lid with respect to the fixing members 13 and 14 are of the insertion type, the image of the assembled container is as shown in FIG. 12, and the perspective view thereof is as shown in FIG. In addition, when the latches on both sides of the lid with respect to the fixing members 13 and 14 are of the hook type, the image of the assembled container is as shown in FIG. 14, and the perspective view is as shown in FIG.

  Here, when each locking at the tongue 13a and the insertion port 13b of one fixing member 13 is released, the folding margin members 6 and 9 sandwiched between the fixing member 13 and the side member 2 can be opened. It is possible to open only the side surface of the container by tilting only the side surface member 2 to the same plane as the bottom surface member 1, and food can be taken in and out from the side surface.

  Next, a method for folding the container compactly to carry it will be described. As shown in FIG. 8, the container is returned to a sheet shape, and the container is emptied. The procedure for returning the container to a sheet may be the reverse of the assembly described above. From this state, as shown in FIG. 9, the lid members 11 and 12 and the side members 3 and 5 connected to the lid members 11 and 12 are folded so as to overlap the inner surface of the bottom member 1 in a Z shape.

  Subsequently, as shown in FIG. 10, the one fixing member 14 and the side member 4 connected to the fixing member 14 are folded so as to further overlap the lid member, and further, as shown in FIG. 11, the other fixing member 13 and the side member 2 connected to the fixing member 13 are folded so as to overlap each other. The seat is fixed in a compact folded state.

  As shown in FIG. 16, the assembled container can be carried with a handle by attaching a cover with a handle. The cover is formed in a band shape having the same width as the width in the longitudinal direction of the container, and arches serving as handles are formed at both ends of the band. The length of the band is set to a length that just circulates the bottom member 1 of the container, the side members 3 and 5 of the longitudinal surface, and the lid members 11 and 12, and is formed at both ends of the band at the upper part of the container. By facing the arches, the arches become handles. Moreover, the fixing | fixed part which connects the said both ends detachably is provided in the both ends of the belt | band | zone, The said fixing | fixed part is comprised with a hook_and_loop | surface fastener, for example. When removing the handle, release both ends of the band and remove the band from the container. This cover can be used as a cover for wrapping a folded container as shown in FIG.

  As described above, according to this embodiment, the container can be compactly folded and carried, and since the resin bottom member 1 and the side members 2 to 5 are not perforated, the liquid material is not in use. It has a structure that does not leak. Further, by releasing the locking of the fixing members 13 and 14, the container can be returned to a single resin sheet, so that it can be washed and used repeatedly. Furthermore, since the container and the lid are integrated by a single sheet, there is no troublesome handling of the container and the lid separately even when folded. As described above, food can be taken in and out from the side of the container.

  Therefore, according to this embodiment, when carrying a foodstuff, the folding container suitable for the objective of putting and carrying a foodstuff in an assembly container (folding container), and using this container repeatedly can be provided.

  Next, another embodiment of the present invention will be described with reference to FIGS. In the following description, the same reference numerals are given to the portions corresponding to the embodiments described above.

  In the previous embodiment, by attaching the ribbon-like member 15 to the side members 2 and 4, the insertion ports (first locking portions) 2 a and 4 a are provided in the side members 2 and 4. If the insertion port is directly cut into the side members 2 and 4, the contents may leak from the cut, so that the ribbon member 15 can be attached to the side members 2 and 4 without cutting. Inserts 2a and 4a were provided.

  However, in this case, a process for attaching the ribbon-like member 15 to the side members 2 and 4 is required. In the present embodiment, this step, that is, the step for attaching the ribbon-like member 15 to the side members 2 and 4 is unnecessary.

  FIG. 17 is a development view of this embodiment. Compared with the development view of the previous embodiment shown in FIG. 1, in this embodiment, instead of the insertion ports 2a and 4a formed by the ribbon-like member 15, when the folding margin members 6 to 9 are assembled, The insertion ports 2a and 4a are formed in the respective portions by cutting.

  In addition, the shape of the fixing members 13 and 14 is changed to a substantially square shape, and the velocities 13a and 14a corresponding to the positions of the insertion ports 2a and 4a are provided at the two corners on the distal ends of the fixing members 13 and 14, respectively. It is formed by cutting. When assembling the container, a total of four tongues formed on each of the fixing members 13, 14 are respectively inserted into a total of four insertion ports formed on each of the folding margin members 6-9. Yes. The configuration of the other parts is the same as that of the previous embodiment.

  Then, when assembling the container, as shown in FIG. 18, the side members 2 to 5 are raised to the center, and the folding margin members 6 to 9 are arranged along the outside of the side members 2 and 4 connected to the fixing members 13 and 14. Bend each so that.

  Subsequently, as shown in FIG. 19, the fixing members 13 and 14 are covered on the folding margin members 6 to 9, and a total of four tongues 13 a and 14 a formed on the fixing members 13 and 14 are connected to the folding margin members 6 to 6. 9 is inserted into the outlets 2a and 4a exposed to the outside. Similarly to the previous embodiment, when the lid members 11 and 12 are closed and fixed, the container is completed. The side surface seen from the opposite side of FIG. 19 appears as shown in FIG. Moreover, when FIG. 20 is represented by a perspective view, it appears as shown in FIG.

  When the container is folded, it is folded so that both side surfaces in the longitudinal direction overlap the bottom surface as shown by arrows in FIG. 22, and then both side surfaces in the short side direction are further folded as shown by arrows in FIG. Thereby, like the previous embodiment, it can be compactly folded and carried and stored.

  According to the present embodiment described above, unlike the previous embodiment, a process for attaching the ribbon-like member 15 to the side members 2 and 4 is not necessary.

  Here, the scope of the present invention is not limited to the above embodiments, but is the scope of the invention described in the claims. For example, the sheet only needs to be waterproof, and the type of specific material is not limited. In addition, the lid member of the embodiment is divided into right and left parts, and closes the container by overlapping in the center. Also good. The locking structure between the members is not limited as long as the hole is not formed in the side member. Moreover, the ratio of the dimension of a container and the shape of the outline of the sheet | seat shown in a figure may differ.
