【Example】

 In the first embodiment shown in FIGS. 1 to 13, a left wall 3 is provided on a left edge of a front wall 1 via a fold line 2, and a front glue margin 5 is also integrally provided via a fold line 4. After the front left half 6 and the right wall 9 on the right edge of the rear wall 7 are connected to the right wall 9 via the fold line 10 and the rear glue margin 11 is also integrally connected via the fold line 10, respectively. The right half 12 is made of cardboard, and the front glue margin 5 is adhered to the front edge of the right wall 9 and the rear glue margin 11 is adhered to the rear edge of the left wall 3 and The left half 6 and the rear right half 12 are connected to form a square tubular body 13 and to be folded into the lower edges of the front, rear, left and right walls 1, 7, 3, 9 respectively. The front bottom portion 18, the rear bottom portion 19, the left bottom portion 20, and the right bottom portion 21 are connected to each other via the lines 14, 15, 16, 17, and the left portion 23 of the front bottom portion 18 and the front portion 24 of the left bottom portion 20 are connected. The right side portion 25 of the bottom portion 19 and the rear side portion 26 of the right bottom portion 21 are laminated and adhered, and 傾斜 right-angled inclined fold lines 27 and 28 are formed inside the laminated portions at the left bottom portion 20 and the right bottom portion 21. When the body 13 is formed in the shape of a rectangular cylinder, the front, rear, left, and right bottoms 18, 19, 20, 21 are engaged with each other to automatically form the bottom 29, and the bottom 29 is formed. The same applies when the torso portion 13 is crushed so that the left wall portion 3 overlaps the back side of the front wall portion 1 and the rear wall portion 7 overlaps the back side of the right wall portion 9 while pushing the center portion of the portion 29 inward. The bottom part 29 is automatically folded, and the upper edges of the front, rear, left, and right walls 1, 7, 3, and 9 are folded through folding lines 31, 32, 33, and 34. The front cover 35, the rear cover 36, the left cover 37, and the right cover 38 are connected in series, and the left and right covers 37, 38 are connected to each other. -Tongue-shaped locking pieces 39, 40 for maintaining the lids 35, 36, 37, 38 in a closed state and the slit insertion holes 41, 42 of the same are provided on the rear lids 35, 36, respectively. At the same time, a pair of cuts 43 and 44 are cut out on both sides of the central portion of the front edge of each of the front, rear, left and right lids 35, 36, 37 and 38 to form a tongue-shaped maintenance piece 45. When the front, rear, and lids 35, 36, 37, and 38 are folded over the front, rear, left, and right walls 1, 7, 3, and 9 respectively, the retaining pieces 45 are formed. By providing a U-shaped cutting line 46 at a position corresponding to the above, an insertion hole / handle hole 47 for the retaining piece 45 is formed, and further, the left and right wall portions 3 and 9 and the left and right bottom portion 21 are formed. , 22 and the left and right lids 37, 38 are provided with left and right folding lines 48, 49 at the vertical center lines.

In the above-mentioned embodiment, when it is desired to make the folding state, for example, first, as shown in FIG. 8, the front / rear / left / right lid portions 35, 36, 37, 38 are front / rear / left / right walls. After folding over the outside of the parts 1, 7, 3, 9 and inserting the retaining piece 45 into the insertion hole / handle hole 47 and stopping it, the central part of the bottom body part 29 is pushed inward (upward) and While the bottom body 29 is in the folded state, the places where the left and right folding lines 48 and 49 are provided (see the white arrows in the drawings) are pushed inward (see FIGS. 12 and 13). It is a good thing.

When folded as described above, as shown in FIGS. 9 and 10, the left wall 3, the left bottom 20, the left lid 37 and the right wall 9, the right bottom 21, and the right lid 36 are in front. The front wall 1 is folded between the wall 1 and the rear wall 7, that is, the whole is the size of the front wall 1. For example, as shown in FIG. It can be stored and transported in an orderly manner. In order to be able to do so, it is necessary to make the inner dimension between the left and right wall sections 3 and 9 slightly wider than the width of the front and rear wall sections 1 and 7. It is desirable that the inner dimensions and the dimensional relationship of the width should be such that the box inside does not play and there is no space.

[0008] Then, the user who has obtained a large number of (a large number of) boxes in one box, takes out one of the boxes and uses the outer box at the end. I do.

When the contents are to be stored in the extracted box, the central portion of the bottom body 29 is outwardly (downward) while the locations where the left and right folding lines 48 and 49 are provided are pulled out. It is returned to the box shape by pushing it out, the contents are put in this returned state, and after this storage, the retaining piece 45 is removed from the insertion hole / handle hole 47 and then the front / rear / left / right cover The portions 35, 36, 37, and 38 may be closed, and the locking pieces 39 and 40 may be inserted into the insertion holes 41 and 42 to maintain the closed state.

When the contents are put into the box, the retaining piece 45 is inserted into the insertion hole / handle hole 47 and stopped, so that the front / rear / left / right lid portions 35, 36, 37, 37 is maintained in a completely stopped state, so that the lids 35, 36, 37, and 38 do not become a hindrance that protrudes sideways.

A second embodiment shown in FIGS. 14 and 15 is a locking piece for maintaining the closed state of the front / rear / left / right lids 35, 36, 37, 38 and insertion of the same. The position of the hole is different from that of the first embodiment, and the other parts are almost the same.

The present invention can be made of a material such as paper cardboard, plastic cardboard, cardboard or plastic board, and the means for keeping the lid closed is not limited to the above-mentioned locking piece. For example, the method may be performed by an adhesive tape fixing method or the like.

In the figure, reference numeral 52 denotes a fold curve which is bent when a finger is hooked on the finger hooking hole 51 and pulled to facilitate the operation of pulling out and inserting the maintenance piece 45.

[0014]

[Effect of the invention]

 The foldable box according to the present invention is composed of a body composed of the front, rear, left, and right walls and a lower edge of the front, rear, left, and right walls, which are continuously provided through the folding line as described above. The left and right bottoms are provided via folding lines, and the left part of the front bottom and the front part of the left bottom are superimposed, and the right part of the rear bottom and the rear part of the right bottom are overlapped and adhered. And a self-folding bottom body constructed by providing a 1/2 right-angled inclined fold line inside the overlapping and sticking points at the left bottom and right bottom, and on the front, rear, left and right walls. Front / rear / left / right lids provided at the edges with folding lines, and folding lines provided at the vertical center line of the left / right wall, left / right bottom and left / right lids When folded as described above, the left and right walls, the lid, the bottom, and the rear wall are folded behind the front wall. In other words, the size is about half the size of the conventionally known type, which is extremely effective in resolving the inconvenience caused by the bulkiness, and is extremely effective. As described above, it is possible to transport and store a large number of units in a single box, which is extremely convenient.In addition, add a folding line to the conventional configuration. It is economical because it does not incur high cost because it suffices. Moreover, folding and assembling operations are extremely easy and practical.
