[Industrial applications]

 The present invention relates to a shock absorber installed at a corner of a packaging box.

[0002]

[Prior art and problems]

 Conventionally, foamed polystyrene was used as this type of cushioning material, but foamed polystyrene and other plastic materials do not decompose when left to stand naturally and generate black smoke and unpleasant odors when incinerated. There are various problems in waste disposal, such as damage to the incinerator and damage to the incinerator. Therefore, instead of the styrofoam-made one, a buffer body was proposed in which a plurality of cardboards laminated in a laminated state were cut into a predetermined shape, but such a buffer body takes time to bond the cardboards. I also found that there is a problem that the paper dust generated during cutting enters between the core and the liner of the corrugated board and the work of removing it is a little troublesome.

The present invention has been made in view of such circumstances, has few problems in disposal and can be easily manufactured, can be easily assembled in use, and has a sufficient cushioning effect. It is an object to provide the obtained corner cushioning body.

The lower edge of the base plate is set to a height so as to abut the upper surface of the base plate (3), and the end of the base plate has a lateral width capable of being pressed against the inner wall portion (12) of the first standing wall. By pressing the inner wall portion (12) of the first standing wall toward the outer wall portion (11), the first standing wall (B) and the second standing wall (C) can surely form a right-angled corner portion inside thereof. Has been done.

Thus, the cushioning body having the above structure is transported and stored until it is in a flat expanded state until it is used, and is assembled from the expanded state at the time of use. When assembling it, first, the second intermediate plate portion (5) of the base plate portion is folded over the first intermediate plate portion (4) into two folds, and the inside of the outer wall portion (21) of the second standing wall is folded. The outer wall portion of the first standing wall for stacking the first intermediate plate portion (4) and the second intermediate plate portion (5) in the two-fold shape on the bottom wall portion (1) of the base plate portion bent at 90 degrees. Bend (11) 90 degrees inward with respect to the second outer wall portion (21). Then, as shown in FIG. 5, when the base plate upper plate portion (3) is bent in the direction of the arrow and overlapped on the second intermediate plate portion (4), the projecting edge (7) becomes the second standing wall outer wall portion. It is automatically fitted and locked in the fitting and locking part (31) of (21).

Next, the first standing wall second intermediate wall portion (14) is folded back inside the first intermediate wall portion (13) into a two-fold shape, and both intermediate wall portions (13) and (14) are formed into inner wall portions. After being folded back into the inside of (12) to form a triple layer, when these are combined and folded back inside the second vertical wall outer wall portion (11) as shown by the arrow in FIG. The four-fold first standing wall (B) vertically assembled from the standing wall outer wall portion (21) is assembled. In this state, the inner wall portion (12) and the intermediate wall portions (13) and (14) have their leading edges abutting against the inner surface of the second standing wall outer wall portion (21), and the inner and outer wall portions (12) (11). By connecting the connecting portion (15) between the two) to the cutout portions (18) and (19) of the first and second intermediate wall portions, they are securely held, and the external force in the direction opposite to the arrow shown in FIG. This state will not be released unless is added.

Then, finally, the second standing wall second intermediate wall portion (24) is folded back inside the first intermediate wall portion (23) into two folds, and further, both intermediate wall portions (23) and (24) are formed. After folding back to the inner side of the inner wall portion (22) to form a triple layer, when these are combined and folded back inside the second standing wall outer wall portion (21) as shown by the arrow in FIG. 7, as shown in FIG. The quadruple second standing wall (B) is vertically assembled on the base plate portion. In this state, the inner wall portion (22) and both the intermediate wall portions (23) and (24) are brought into contact with the inner surfaces of the first standing wall inner wall portion (12) at the leading edges, and the inner and outer wall portions (22) (21) By fitting the connecting portion (25) between the two) into the notches (28) and (29) of the first and second intermediate wall portions, it is securely held, and external force in the direction opposite to the arrow shown in FIG. 7 is applied. This condition will not be released unless joined.

It should be noted that the projecting edge (7) of the base plate upper plate part (3) and the fitting locking hole (31) of the second standing wall outer wall part (21) are better for facilitating the assembling operation. Desirable but not essential.

[Effect of device]

 According to the above, the shock absorber according to the present invention is an excellent shock absorber because all of the base plate portion (A), the first standing wall (B) and the second standing wall (C) are configured as quadruple walls. In addition to being able to obtain the effect, the whole body is cut from a single piece of corrugated board, so it can be folded flat until it is ready for use, and the transportation and storage space can be made as small as possible. At the same time, it can be assembled by a simple operation.

Moreover, the first and second intermediate wall portions (13) and (14) and the inner wall portion (12) of the first standing wall (B) are erected on the upper surface of the base plate portion (A), and the second The first and second intermediate wall portions (23) (24) and the inner wall portion (22) of the standing wall (C) are to be erected, and the first and second intermediate wall portions (of the second standing wall (C) ( 23) (24) and at least one of the inner wall portions (22) are set so that their end portions have a width capable of being pressed against the inner wall portion (12) of the first standing wall (B). The assembled state is securely maintained by pressure contact, and no separate adhesive, stapler, adhesive tape, etc. are required. Therefore, when dismantling the shock absorber after use, it can be returned to the original flat developed state by an operation opposite to the assembling operation, and the disassembly workability is extremely good. Moreover, since it is made of corrugated cardboard, it has the advantage that there are few problems in terms of disposal.
