The present invention relates to a folding box that can minimize the volume during transportation and storage of the empty box.

Conventionally, plastic boxes, which are used to accommodate contents such as beverages, alcoholic beverages, and fruits, require a lot of cost and space for transportation and storage because they maintain their original volume and shape even when the contents are empty. In order to solve this problem, a prefabricated box as disclosed in various folded or domestic utility model publication Nos. 86-9726 (assembly box) has been proposed. However, conventional folding or prefabricated boxes have disadvantages that the assembly or folding work is inconvenient, or the rigidity of the assembled state is insufficient and the handling during disassembly is not easy.

Accordingly, an object of the present invention is to solve the disadvantages of the conventional folding box as described above, to provide a folding box that is easy to assemble and fold, excellent rigidity, easy to assemble and folded upper limbs.

The object is, according to the present invention, a collapsible box having a substrate having a substantially rectangular plate shape and four sidewalls hingedly rotatably hinged to each side of the substrate, wherein any two of the four sidewalls face each other. At least one locking projection protruding from the outer surface of the edge edge region of the projection and protruding from the inner surface of the opposite edge region of the two opposite side walls, the locking projection for accommodating the shape of the locking projection of the adjacent side wall in one rotational direction It is solved by a collapsible box comprising ribs.

Corresponding locking jaw and the locking jaw receiving ribs are formed to be prevented from being separated from each other in any other direction except the engagement rotation direction to facilitate the assembly work and to maintain the assembled state reliably. It may further include a fixing means for fixing them integrally in order to prevent the mutual separation of the engaging jaw and the engaging jaw receiving ribs interlocked with each other.

In order to obtain a folded state that is easy to handle, it is desirable that each side wall be folded and stacked on the substrate. Here, the substrate is formed in conformity with the upper surface portion of the folded box so as to fit on the other box in the folded state can be effectively stacked and stacked folded boxes.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a folding box according to the present invention. As can be seen from this figure, the folding box has a substrate 1 having a substantially rectangular shape, and four side walls 2 and 3 are hinged to each side of the upper surface of the substrate 1. These four side walls 2, 3 consist of two opposing short side walls 2 and two opposing long side walls 3, respectively, which are connected to the substrate 1 on the substrate 1 by hinge pins 4 and 5, respectively. It is installed so as to be able to rotate around each side of 1), and preferably, it can be rotated only inward to achieve folding and assembling rigidity. Each side wall (2, 3) and the substrate (1) is composed of a plurality of lattice shape for strength increase and material saving, and reinforcing ribs are formed in appropriate places. A plurality of locking jaws 6 having a trapezoidal planar shape is formed on the outer surface of both edge edge regions of the long side wall 3, and the locking jaws 6 are formed on the inner surface of the corner region of the short side wall 2 by A locking jaw receiving rib 7 for receiving is projected.

FIG. 2 is an enlarged perspective view showing an enlarged portion of the locking jaw 6 and the locking jaw receiving rib 7 of FIG. The plurality of locking jaws 6 protruding toward the outside of both edge edge regions of the long side wall 3 protrude in a trapezoidal shape with a wide corner side and a narrow inner side. The locking jaw receiving ribs 7 protruding inwardly from the end wall 2 and the edges of both ends are composed of a plurality of rib types 8, and each rib type 8 protrudes in an inverted trapezoid shape to form each rib type 8 Between the) is formed a space for accommodating the locking jaw (6) to accommodate. By the configuration of the engaging jaw 6 and the engaging jaw receiving rib 7, the long side wall 3 is rotated about its hinge portion 5 while the short side wall 2 stands up. (6) is accommodated between the rib-shaped molds 8 of the locking jaw receiving ribs 7, so that the short side walls 2 and the long side walls 3 are brought into engagement with their edges.

In order to facilitate the engagement between the locking jaw 6 and the locking jaw receiving rib 7, the frictional contact surfaces of the locking jaw 6 and the locking jaw receiving rib 7 are inclined as shown in FIG. consist of. And by this slope the locking jaw (6) does not pass through the locking jaw receiving rib (7) can easily perform the assembly work. In addition, the locking jaw 6 and the receiving rib 7 engaged with each other by the trapezoidal shape of the locking jaw 6 are reliably prevented from being separated in the direction perpendicular to the locking direction.

In this way, when the engaging jaw 6 and the engaging jaw receiving ribs 7 at the four corners are engaged, all side walls 2 and 3 stand up from the substrate 1 to form a box in which the contents can be accommodated. .

However, since the contact surface where the latching jaw 6 of the engaging jaw 6 and the engaging jaw receiving rib 7 meets is made up of a slope in the biting direction, a partition grating therein exists to contain the contents or contain the contents therein. In this case, the long side walls 3 are supported by them so that they can remain in bite with the short side walls 2, but without them, the long side walls 3 are likely to escape inwardly with respect to the short side walls 2.

Therefore, in order to maintain the bite state of the long side wall (3) and the short side wall (2) can be used a fixing pin (11) inserted across the engaging jaw (6) and the receiving rib (7). In order to insert the fixing pin, the engaging jaw 6 and the receiving rib 7 have through holes 9 and 10 as shown in the drawing. The fixing pin 11 fixes the catching jaw 6 and the receiving ribs 7 integrally when assembling the box, and when folding the box, the through holes 9 of the catching jaw 6 or the receiving ribs 7, 10) just plug it in. Alternatively, one of the side walls 2 or 3 may be formed and stored in a suitable hole for accommodating the fixing pin 11.

A long side wall (3) and a short side wall (2) are formed by forming a fixing jaw inside the short side wall (2) together with or instead of the fastening pin (11) in FIG. The fixed state of the liver can be easily secured. The fixing jaw 12 has a slope in the standing rotational direction of the long side wall 3 and forms a locking step for preventing the long side wall 3 from being separated in the reverse direction. The fixing jaw 12 may be simply protruded from the inner surface of the short side wall 2 or installed outwardly through an elastic spring. As a result, the fixing jaw 12 is deformed by the elasticity of the short side wall 2 or the elasticity of the built-in spring when the long side wall 3 stands up, and the long side wall 3 between the holding jaw receiving ribs 7. To prevent it from falling off. When releasing the long side wall 3 from the short side wall 2, the short side wall 2 is elastically deformed, or the locking jaw 6 and the locking jaw receiving rib 7 are pushed by pressing the fixed jaw 12 with the spring embedded therein. Release the bite.

3 to 5 show other embodiments of the locking jaw 6 and the locking jaw receiving ribs 7. In the embodiment of Fig. 2, the planar shape of the latching jaw 6 is trapezoidal, but in Figs. 3 to 5, it is formed into a rectangular, T-type or similar T-shape. In addition, in these embodiments, unlike in the embodiment of FIG. 2, the hooking jaw accommodation portions are not opened but are connected to each other, whereby the strength of the receiving ribs is further enhanced. And the inclination of the contact surface, the fixing pin, etc. for ease of assembly may be applied as in the embodiment of FIG. In order to achieve the spirit of the present invention, the shape of the locking jaw and the locking jaw receiving rib is not limited to the example shown in FIGS. 2 to 5, and many modified shapes may be used.

6 is a front view of a folded state of the folding box according to the present invention. Each side wall 2, 3 of the present box can both be turned inward, ie on the substrate 1, overlapping each other. First, in the state in which one of the two long side walls 3 is folded on the substrate 1, the remaining long side walls 3 are placed thereon, and then the short side walls 2 are rotated in turn to be stacked. For this purpose, the positions of the hinge portions 4 and 5 of the respective side walls are correspondingly formed stepped. This folded empty box is adapted to be superimposed on another folded box as shown by the dotted line. To this end, the substrate 1 of the box is formed to correspond to the top shape of the folded box.

As a result, a large number of folded states can be stacked and transported or stored in a stable manner, and the handling is very easy because the folded state is compact. In the state shown in FIG. 6, the boxes are engaged not to move with each other only in the long axis direction, but the outer surfaces of the sidewalls and the bottom surface of the substrate 1 are appropriately formed so as to fit in both the long axis and the short axis directions. It can be done. The stacked box thereby can be held firmly engaged in the forward direction.

In addition, even when the box is assembled to accommodate the contents, the upper edge of the side wall of the standing state and the lower edge of the substrate 1 may correspond to each other so that the assembled boxes may be properly stacked on each other. In addition, a separate grid member or a lid for protecting contents may be provided to separate and maintain contents.

As described above, the folding box according to the present invention is easy to assemble and fold, and to minimize the volume of the empty box provides an effect that can significantly reduce the storage and transportation costs.
