Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to carrying a container by vacuum or pressure integrated molding of a thermoplastic resin.

2. Description of the Related Art In supermarkets or shops, molded containers for foodstuffs, small items, etc. are made from resin sheets or by injection into boxes for finished containers. There is also one in which a box is punched out into a flat plate and then assembled. For example, Japanese Utility Model Publication No. 54-11164 is known.

Problems to be solved by the invention The former one is bulky because it is molded into the shape of a completed box. Still, if the boxes have the same shape, they can be stored by stacking, which is not so great, but if there are many types, the shapes do not match and it becomes difficult to store them in a stack, and a considerable space is occupied. In addition, since the box has no handbag, it is inconvenient to carry, and if the handbag is attached later, the cost becomes high and the mounting strength is weak.

Also, the latter one, which is Japanese Kokoku Publication No. 54-11164, is a baby carrying carrying box that can be unfolded and assembled, and the carrying bag is not made in one piece but has a loop-shaped hanging strap fixed to it for storing small items. Is an unsuitable structure, and there is a cost problem to install it later.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a container bag having sufficient strength with low cost of containers for foods, small articles and the like. To do.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention continuously molds each end of a strip-shaped handbag integrally with the separated side ends of adjacent side plate portions of a deployed box body. A pair of male and female hooks, each of which has a protrusion protruding from the surface of one of the handbags and a female female hook having a recess on the back surface of the other handbag, are formed in the central portions of the two handbags. The male and female hooks are connected by turning the center over and stacking the front surface and the back surface on top of each other.

Action A pair of handbags formed at the mouth edge of the container or a pair of handbags of the box body that is formed by folding and expanding the four side plates of the box material are vertically stacked at the center to form a convex shape. Fit male and female hooks and connect.

EXAMPLE An explanation will be given below with reference to FIGS. 1 to 6.

The unfolded box body is, for example, in the form of unfolding from a rectangular parallelepiped, and side plates 2a, 2b, 2c, 2d are connected to the bottom 1 on all four sides, and the bent portion of the side plate is bent so that the bending side is concave. A groove 3 is formed to help. This groove 3
Do not necessarily need to be continuous, and may be recesses arranged in a line.

Further, it is premised that the insertion piece 5 having the detents 5a on both sides or one side at the abutting portions at both corners of the side plates 2b, 2d or 2a, 2c as the connecting portion of the side plate portion or the tip is folded back. Inserting pieces 6 having no detent are provided so as to project in parallel with the grooves 3 of the respective side plate portions. Then, it is preferable to form a groove 4 on the insertion base of the bent portion, the groove 4 being concave on the bending side to assist the bending. The notch 7 into which the insert pieces 5 and 6 are inserted has a width equal to that of the insert, and is provided at a position where the detent 5a is just in parallel with the insert of the mating side plate portions 2a and 2c or 2b and 2d. In addition, a large key 15a is formed on the side above the insertion piece 15 and the cut 7
The width m of the inserted piece 15 including the key, the height l to the upper end of the cut is equal to the height l to the upper edge of the cut, and the length n from the side plate abutting end to the cut Is equal to the length n up to the insertion key 15a.

A hook connection may be used as another form of the connecting portion. That is, the protrusions 8 provided at the both side abutting portions of the side plate portions 2b, 2d or 2a, 2c are provided with the convex portion 9 having a repellent cross section, which is a male hook, on the inner side of the box. A recess 10 having a repellent cross-section, which is a female of a hook, is provided on the side plate portion serving as a mating piece so as to open outside the box. This hook has two or three hooks depending on the depth of the box.

Further, as the size of the formed box becomes larger, the side plate portions 2a, 2b, 2c, 2d have reinforcing bending portions 11 on the outer edges, an X-shaped rim or a concentric rim 12 on the bottom portion 1 so that the box does not become sticky, and A V-shaped rim 13 or the like is formed on the side plate portions 2a, 2b, 2c, 2d as needed. The unfolded box base described above is formed in a flat plate shape.

As a development of this box material, a partition is required in order to keep the items to be housed neatly and not gathered even when carrying them. Therefore, the partition 14 is formed as a rib on the bottom part 1 at the time of molding. is there. The height of the ribs of the partition 14 can be freely formed, but is preferably about 1/2 of the depth.

These expanded box materials are formed integrally from a thermoplastic resin sheet by vacuum or pressure forming using a mold and then cut along the expanded contour.

To assemble the expanded box material into a box, the side plate parts 2a, 2b, 2c, 2d
Is bent substantially at a right angle in the groove 3 with respect to the bottom portion 1 to deform the insert piece 5 or 6 on the outside of the mating side plate portion, and the groove 4 of the insert base portion bends the tip into the notch 7 to the inside from the outside. Insert towards. A detent 5a wider than the width of the notch 7 engages the end of the notch to hold the side plate firmly.
In the case of the insert piece 6 without the detent, or the insertion tip of the insert 5 with the detent is folded back at the cut piece 7.
Since the material is made of resin instead of paper, the folded back end does not return and keeps the bent state to securely connect the side plate parts. Further, when the insertion piece 15 is bent downward and inserted into the notch 7 and the key is passed through and then retracted, the upper end of the notch 7 and the upper edge of the insertion 15 are aligned by the elasticity of the resin, and the key 15a is Engage. Further, in the case of the hook type, by fitting the convex portion 9 of the protruding piece 8 which is bent outwardly into the concave portion 10, the side plate portions are reliably connected.

Further, in another embodiment shown in FIG. 7, one side 16a, 16d of the L-shaped strap portion is formed on the outside of each of the adjacent side plate portions 2a, 2d and 2c, 2b of the expanded box material of FIG. L-shaped 1
The sides 16c and 16b are formed. That is, the belt-like carrying parts 16a and 16d
Are connected to each other in an L-shape, and at the other ends thereof, they are integrally formed and connected to the adjacent side plate portions 2a and 2d, and the middle portion is cut. Further, the handbags 16b and 16c are connected to each other in an L shape, and the other ends of the respective handbags 16b and 16c are integrally formed and connected to the adjacent side plate portions 2b and 2c, and an intermediate portion is cut. And 16a to carry
And 16d so that the female hook has a cross-section repellent concave portion 17 opened downward in the figure, and the male hook has a cross-section repellent convex portion 18 at the center joints of the carrying parts 16b and 16c. Are formed so as to project upward in the figure. Therefore, the bulging side of the concave portion 17 and the convex portion 18 are also formed on the upper side in the figure. When molding, place the mold on the lower side of the figure
The sheet material is not thin, and the hook fitting is firm. To assemble this box material, after assembling the box as described above, the connecting portions of the handbags are combined and the recesses 17 and the projections 18 are fitted by hooks as shown in FIG.

Although it was explained with the box material, it is not limited to the box shape,
Further, it is needless to say that the same can be applied to a lid having a depth and that the lid can be integrally formed on the side plate portion of the box material.

Effects Since the present invention is configured as described above, the present invention has the following effects.

Since the pair of handbags is integrally formed on the side plate or the rim portion, the cost can be much lower than the case where the handbag is attached later. In addition, since it is integrally molded, it has sufficient carrying strength and does not separate at the carrying mounting part. Further, since the hooks are formed by stacking the connection of the handbags on top of each other and formed in the center, the surface to be received by the hand is flat and soft feeling can be obtained in the state of being handheld.

Furthermore, since it is a hook connection, the connection can be easily removed when storing the container, and storage is easy.
