DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packing packing case which can be used for packing household goods and industrial packing using cardboard boards.

[0002]

2. Description of the Related Art FIG. 4 is a view for explaining an example of a conventional packing packing case. FIG. 4 (A) is a development view of the packing packing case, and FIG. FIG. 4 (B) is a front view showing the front panel when folded. In FIG. 4, 30 is a packing case for packing, 30a is a convex piece for insertion, 30b is a cut in a convex piece, 30c is a slit, 30d is a convex piece in a slit portion, S
Is a slit notch. As shown in FIG. 4, in the conventional packing case, the shape of the slit 30c is rectangular, and when a three-dimensional assembly is to be obtained, first, the slit 3c is bent by valley bending.
The portion of 0c is opened, and the insertion convex piece 30a is inserted into the slit cut S provided on both sides of the slit 30c. Then, the convex piece cut 30b provided on the neck of the insertion convex piece 30a is made to coincide with the slit cut S, and the insertion convex piece 30a is moved in the direction of arrow F, thereby obtaining FIG. As a result, a three-dimensional assembly is obtained as shown in FIG.

[0003]

In the assembly of the conventional packing packing case, the insertion of the tip of the insertion convex piece 30a into the slit notch S shown in FIG. The cost is high for mass production. Further, with respect to the shape stability at the time of completion of assembly, for example, when a force in the direction of arrow G is applied to the packing case, the insertion convex piece 30a is displaced, and the convex piece cut 30b and the slit cut S become one. As a result, the convex piece for insertion 30a falls off (falls off).
Inconvenience occurs.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and has assembling easiness and assembling stability in a three-dimensional assembly, absorbing a shock from the outside to reduce a buffering effect on a packaged object. An object to be solved is to provide a packing packing case to be provided.

[0005]

A first aspect of the present invention is a packing packing case using an assembled product obtained by bending and assembling a plate-like member having a convex portion and a cut portion,
In a packing packing case to be inserted into the opening formed in accordance with the shape of the notch in the bent state, the convex pieces are inserted into each other and locked together, the shape of the opening is trapezoidal, In a state where the convex piece is inserted into the opening, so that the convex piece does not move unnecessarily in the height direction of the trapezoid, the locking portion of the convex piece is on the long side of the trapezoid. to conform to the bottom portion, further wherein
A cut-and-raised portion is provided on the convex portion, and the convex portion is
When inserted, the protrusion is unnecessary in the pull-out direction.
Cut into the wall around the opening to keep it from moving
It is characterized in that the raising portion is engaged .

[0006]

[0007] According to a second aspect of the invention, in the invention of claim 1 Symbol placement, provided with four points in the outer peripheral portion of the plate-like member to the convex piece, the opening for locking the each of the convex piece The cutouts for forming the plate were provided at four positions, and the shape of the plate-like member and the positions of the convex pieces and the cutouts were set so as to form a concave portion in which the article to be packed was to be installed. It is characterized by the following.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a view for explaining an embodiment of a packing packing case of the present invention. FIG. 1 (A) is a development view of the packing packing case, and FIG. 1 (B) and 1 (C) are a front view and a side view, respectively, of the assembled product obtained by folding and assembling the packing packing case of FIG.
It is shown in FIG. In FIG. 1, reference numeral 10 denotes a packing packing case, 10a denotes an insertion convex piece, 10b denotes a stopper portion (cut and raised portion), 10c denotes a slit, and 10d denotes a slit convex piece. 1 (B) and FIG. 1 (B) by folding a paper board made of cardboard or the like shown in FIG. 1 (A).
A three-dimensional assembly as shown in FIG. At this time,
The shape of the opening obtained by the slit 10c is set to be trapezoidal, and an insertion protruding piece 10a having a width substantially the same as the width of the base is inserted into the base on the wide side of the trapezoid. Since the width of the trapezoidal opening decreases in the direction of arrow D, the movement of the insertion convex piece 10a in the direction of arrow E is restricted. Further, the action of the stopper portion 10b as shown in FIG. 1 (C) ensures the stability of the insertion convex piece 10a in the pulling-out direction. With these configurations, high shape stability when assembled into a three-dimensional shape is obtained. can get.

FIG. 2 is a view for explaining another embodiment of the packing packing case of the present invention, and shows a developed view of the packing packing case. In FIG. 2, reference numeral 20 denotes a packing packing case, 21a, 22a, 23a, and 24a.
Is a convex piece for insertion, 21b, 22b, 23b and 24b are stopper portions (cut-and-raised portions), 21c, 22c, 23c,
24c is a slit, and 21d, 22d, 23d and 24d are slit-shaped convex pieces. FIG. 3 is a view showing a form when the packing packing case shown in FIG. 2 is bent and assembled. FIG. 3A is a perspective view of the assembled product, and FIG.
This is shown in FIG.

The packing packing case in the unfolded state shown in FIG. 2 is folded in a valley in the order of a, b, hal,..., And each of the projecting projections 21a, 22a, 23a, 24a is slit into a slit 21c. The stoppers 21b, 2c are inserted into the trapezoidal openings formed by 22c, 23c, 24c.
By functioning the stoppers 2b, 23b and 24b as stoppers, a three-dimensional assembly is obtained, and a paper box having a double structure is obtained. Inside the three-dimensional assembly, a rectangular parallelepiped space shown as a hatched portion H in FIG. 3 (B) is formed, and precision equipment and the like are housed in the space for storage and protection. Further, as shown in FIG. 3A, a space is formed between the outer wall W1 and the inner wall W2, so that an external impact can be absorbed.

[0011]

As is apparent from the above description, the packing packing case of the present invention can be obtained by only a simple cutout of a single plate-like member such as a paper plate, and a bending press of peaks and valleys. It is a formed structure, high productivity,
In addition, materials can be used efficiently, and costs can be reduced. In addition, it has high strength against external stress after three-dimensional assembly configuration, reliable shape stability,
Buffer performance against external impacts and the like can be obtained.
