  In order for the assembly container to be easy to use, it is desirable that the assembly and opening / closing of the container is simple and that it is easy to load the product.In addition, the container does not open easily due to the load of the contents. It is important to have strength that does not cause waking. In such a point, the assembly container of Patent Document 1 requires a lot of time for assembly, and thus packaging efficiency is not good. In addition, at the end on the short side, the container may be released by being distorted or unassembled due to the load on the contents, so it is necessary to fix the locking part with an adhesive after assembly. It was.

  The present invention provides an assembly container that is easy to assemble and open and close, but is not easily opened by the load of the contents, has an appropriate strength, and is not easily distorted by the load. Let it be an issue.

  In order to solve the above-described problem, according to one aspect of the present invention, an assembly container includes a rectangular bottom surface portion, and a pair of side surface portions facing the bottom surface portion on both long sides of the bottom surface portion. A top plate portion to be connected, a pair of opening / closing portions connected to both short sides of the bottom surface portion, and a folding portion provided to each of the opening / closing portions to connect the opening / closing portion to each of the side surface portions The folding portions are each formed of a single surface, and the connection between the folding portion and the opening / closing portion is valley-folded by refracting the opening / closing portion with respect to the bottom surface portion, and the top plate portion The gist is that both ends of the long side are refracted toward the bottom surface corresponding to the position of the valley fold.

  The top plate is preferably extended longer in the long side direction than the bottom surface.

  Further, it is preferable that a periphery of the opening / closing portion that contacts the top plate portion when the opening / closing portion is refracted is a curve and the top plate portion is curved.

  According to the present invention, it is possible to complete the assembly and closing by loading the product by a simple operation from the state before use folded flat, and to wrap the product instantly. Since the structure is very good and the opening and closing part after assembly is locked so as not to be easily opened, it is advantageous for conveying goods, and an assembly container excellent in display and appearance of goods is provided.

  The assembly container of the present invention is a container formed of a sheet-like material having flexibility and bendability such as cardboard and cardboard. Foods such as confectionery, tea, and dried foods, western / Japanese clothing, and ornaments It can be suitably used for packaging various products such as.

  Before use, the assembly container is created in a state that is glued from the unfolded state and folded in a flat state. When packaging the product, the product can be loaded by a simple operation, and the container is closed together with the assembly of the container. Can be completed. Therefore, an adhesive such as glue or a string is unnecessary at the time of packaging, and packaging and closing can be performed instantaneously. The assembled container has a structure in which the opening of the opening / closing part is suppressed, and the name of the product name or the like is easy to see from a wide angle and has a beautiful appearance.

  Embodiments of the present invention will be specifically described below with reference to examples. 1-3 show one Embodiment of the assembly container based on this invention.

  As shown in the development view of FIG. 1, the assembly container 1 is connected to a rectangular bottom surface portion 2 and a top plate portion 3, a pair of side surface portions, and front and rear ends (that is, short side) of the bottom surface portion 2. It has a pair of opening / closing parts 5 and a folding part 6 provided for each of the opening / closing parts 5. The top plate portion 3 is connected to both long sides of the bottom surface portion 2 via a pair of side surface portions 4, and the opening / closing portions 5 are connected to the respective side surface portions 4 via folding portions 6. . In the development of FIG. 1, adhesive margins f1 and f2 for forming a connection between one side surface portion 4 and the bottom surface portion 2 and a connection between the folding portion 6 and the opening / closing portion 5 are provided. The assembly container 1 is created from the developed state by bonding. However, the adhesive margins f1 and f2 are not limited to this position, and may be provided so as to connect the side surface portion 4 and the top plate portion 3.

  The assembly container 1 before product loading with the adhesive margins f1 and f2 adhered is folded into a flat shape as shown in FIG. 2, and the bottom surface portion and the top plate portion overlap each other. When loading the product, when the top plate portion 3 is separated from the bottom surface portion 2, the bottom surface portion 2 and the top plate portion 3 face each other, the product is loaded into a space surrounded by these and the side surface portion 4, and the opening / closing portions 5 at both ends are loaded. Is refracted with respect to the bottom surface portion 2 and pushed inward, and rises substantially perpendicularly to the bottom surface portion 2, whereby the inside of the assembly container 1 is closed by the opening / closing section 5 as shown in FIG. 1 assembly is completed.

  The assembled opening / closing part 5 of the assembly container 1 is locked by the folding part 6 and maintained in a closed state. When opening, the fingertip is inserted into a substantially semicircular notch 7 provided at the edge of the opening / closing part 5. The opening / closing part 5 is opened by pulling it outward.

  In the assembly container 1, the folding portion 6 that connects the opening / closing portion 5 and the side surface portion 4 is configured by a single surface, so that the connection between the folding portion 6 and the opening / closing portion 5 is valley in the assembled state in which the opening / closing portion 5 is pushed. Fold. That is, since it is in an indented state, when a load in the outward direction from the inside of the container is applied to the opening / closing part 5, the folding part 6 supports the opening / closing part 5 and locks against the load. The opening of is suppressed. On the other hand, if the folding part 6 is composed of a plurality of surfaces, the number of refracted parts increases and the folding part 5 cannot be supported, and the effect of suppressing the opening by such locking cannot be obtained.

  The opening suppression effect by the folding part 5 is highest when the angle of the folding part 6 with respect to the opening / closing part 5 is vertical, but on the other hand, the folding part 5 is easily broken by a load in the short side direction. From the standpoint of strength balance, it is preferable to incline from the vertical direction to such an extent that a triangular pyramid-shaped small gap is formed between the folded portion 6, the side surface portion 4, and both end portions 3a.

  In a state where the container is assembled, the top plate portion 3 is longer in the longer side direction than the bottom surface portion 2 and extends outward from the opening / closing portion 5 to have a bowl shape. The structure extending in this way also supplements the action of suppressing the closed opening / closing part 5 from being opened to the outside.

  In the assembled state, the top plate portion 3 is supported by the opening / closing portion 5, so that the shape of the assembled top plate portion 3 is defined by the shape of the opening / closing portion 5, and when the opening / closing portion 5 is folded, the top plate portion 3. If the peripheral edge in contact with the straight line is a straight line, the top plate part 3 is a flat surface. If the peripheral edge of the opening / closing part 5 is a curved line, the top plate part 3 is a curved surface corresponding thereto. In the assembly container of the present invention, both end portions 3a on the long side of the top plate portion 3 are bent toward the bottom surface portion 2 side, and the presence of this bend improves the strength of the top plate portion 3 and makes it difficult to be crushed. In the embodiment of FIGS. 1 to 3, the opening / closing part 5 has a shape in which the long side of the trapezoid is changed to an arcuate curve, and both end parts 3 a on the long side of the top plate part are refracted to form a fold, The main portion 3b near the center is gently curved, and this embodiment is one of the most effective in terms of strength. Also, the position of the fold where the both ends 3a on the long side of the top plate portion refract corresponds to the position of the valley fold of the fold portion 6, and it opens and closes when the fold of the top plate portion and the valley fold of the fold portion engage with each other. The locking of the part is reinforced.

  FIG. 3 is a perspective view of the assembly container as viewed from the bottom surface side. When viewed from the top plate side, the top plate portion 3 (particularly the main portion 3b) is smoothly curved. Even if the angle changes, the display of the name of the product printed on the top board, the pattern, etc. are easy to see, which is advantageous for product display.

  An opening may be provided in the top plate portion 3 so that the contents can be visually recognized.
