Description

[Detailed Description of the Invention] <Technical Field> This invention relates to an improvement in a packaging device for packaging light or medium weight products using a cushioning material.

<Prior art and its drawbacks> As shown in FIGS. 1A to 1C, this type of conventional packaging device fits cushioning bodies 2 and 3 such as styrofoam at both ends of an object 1 to be packaged, and stores the object in a case 4. It was configured as follows. Case 4 is the first
As shown in Figure C, it is provided with bottom flaps 2a to 2d, a seam 9, and sealing parts 3a and 3b. The bottom flaps 2a to 2d are of known type and can form the bottom of the case 4 with one touch by engaging the flaps with each other. Furthermore, the adhesive 9 is used to attach both ends of a piece of paper using adhesive, staples, or the like. The sealing parts 3a and 3b are sealing pieces 30a and 30b.
It has a known sealing structure composed of sealing grooves 31a and 31b. To assemble the case 4 with the above configuration, prepare a piece of paper in the shape shown in Figure 1C, fold it along the dotted line in the figure, and then attach both ends with white 9 and attach the bottom. The flaps 2a to 2d are engaged to form the bottom, and the packaged object 1 is
and the buffer bodies 2 and 3 are stored from above as shown in FIG. 1B, and the B flap is folded and sealed. FIG. 1A shows an external view of the packaging device after sealing. In addition to packaging devices having such a structure, as shown in FIG.
3 is wrapped in case 4, and
Next, it has been put into practical use that the packaged object 1, the buffers 2 and 3, and the case 4 are fixed and sealed using a vinyl band 5.

However, in the above-mentioned conventional packaging device, the first
The case shown in the figure has the disadvantage that it requires work such as gluing to assemble the case 4 due to the white seam 9, and the work of assembling the case 4 and loading and unloading the product is relatively complicated. The packaging device shown in Fig. 1 requires sealing with a band to prevent the product from coming off from side to side, which has the disadvantage of poor workability and increased costs.

<Purpose of the invention> The purpose of this invention is to eliminate the above-mentioned inconveniences, and to provide a packaging device that allows easy loading and unloading of products, has good workability, and is low cost.

<Structure of the invention> This invention forms the cushioning body into a shape in which a rectangular parallelepiped part is formed on the inner side and a truncated quadrangular pyramid part on the outer side, and both ends of the sheet-like member are bent inward. The flap is bent so that a triangular flap part is formed on the outside of the bent part and a flat flap part is formed on the inside thereof, and both slopes of the triangular flap are applied to the slopes of the truncated square pyramid part of the buffer body, and the rectangular parallelepiped part of the buffer body is bent. The flat flap is applied to the circumferential surface of the shock absorber to support the sides of the shock absorber.

〈Example〉 Figure 3 shows a packaging device that is an example of this invention, Figure A is an external view of the packaging device when packaging is completed, Figure B is a diagram showing the state in the middle of packaging, and Figure C is a diagram showing the case. FIG.

The object to be packaged 1 is supported at both ends thereof by shock absorbers 2 and 3 made of styrene foam, similar to the packaging apparatus shown in FIG. The buffer bodies 2 and 3 each have a shape in which rectangular parallelepiped parts 20 and 30 are formed on the inner side and square pyramidal truncated parts 21 and 31 are formed on the outer side. Case 4 is shown in Figure 3C,
A single sheet-like member 4' is processed into the shape shown,
Furthermore, a notch shown by a solid line and a bent part shown by a dotted line are formed before assembly. Figure 7
a, 7b and 8a, 8b are sealing parts, which have the same structure as the sealing parts 3a, 3b shown in FIG. 1C. 6a and 6b formed at both ends of the sheet-like member 4'
is the buffer support flap. This shock absorber support flap 6a is cut out along the solid line a in the figure, and is bent along the dotted line b into a mountain fold and the dashed line c into a valley fold. Similarly, the buffer support flap 6b is
It is cut out symmetrically to a and folded again. By processing the shock absorber support flaps 6a and 6b in this way, a triangular flap portion 60 on the outside and a flat flap portion 61 on the inside are formed, and the shock absorber support flap has a bent shape as shown in FIG. 3B. Become. The diamond-shaped portions cut out along line a are for stably holding the triangular flap portion 60. As shown in FIG. 3B, this portion is bent so that the peripheral edges overlap when the case is assembled. Note that when assembling the case, the sealing pieces 70a of the sealing parts 7a and 7b are in the sealing groove 71.
b, and the sealing piece 70b fits into the sealing groove 71a. The same applies to the sealing parts 8a and 8b.

With the above configuration, as shown in FIG. 3B, the inner slope 60a of the triangular flap part 60 comes into contact with the slope 21a of the square pyramid part 21 of the buffer body 2, and the peripheral surface 20a of the rectangular parallelepiped part 20 comes into contact with the slope 21a of the square pyramid part 21 of the buffer body 2. The flat flap portion 61 abuts on the shock absorber support flap 6a, which is composed of the triangular flap portion and the flat flap portion.
The buffer bodies 2 and 3 are supported by 6b. With this, when assembling the case 4, the packaged object 1
Also, it is possible to prevent the buffer bodies 2 and 3 from coming off to the left and right. In addition, FIG. 4A is a perspective view of the left side of the packaging device shown in FIG. 1 seen from three directions, and FIG.
3 shows perspective views of the left side of the packaging device according to the present invention shown in FIG. 3, viewed from three directions. Also the fifth
Figures A and B are views of the buffer body 2 seen from three directions and a perspective view of its appearance, respectively.

<Effects of the invention> As described above, according to this invention, the shock absorber is supported by the flap portion formed by folding both ends of a single sheet-like member inward. There is no need for a band like the conventional packaging device shown in Figure 2, and the size of the case is also reduced, which has the advantage of saving materials. Furthermore, it becomes very easy to take products in and out, which has the effect of extremely improving work efficiency.
