Description

[Detailed Description of the Invention] The present invention relates to a packaging device for packaging items using cushioning material and cardboard.

Conventionally, this type of packaging equipment is as shown in Figure 1.
A cushioning material 2 with recesses formed at both ends of the protected object 1,
3 were fitted together and stored in a cardboard box 4.

In this case, the cardboard box 4 has a shape that completely surrounds the protected object 1 with cushioning materials 2 and 3 fitted at both ends as shown in the figure, so a large amount of cardboard sheets are used, which is not only uneconomical but also The problem was poor packaging workability.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks of the prior art, it is an object of the present invention to provide a packaging device that saves packaging materials and simplifies the packaging process.

The present invention will be explained in detail below along with an embodiment shown in FIGS. 2 to 4.

In FIG. 2, 5 is the object to be protected, 6 and 7 are cushioning materials such as styrofoam, and the cushioning materials 6 and 7 have recesses 8 and 9 formed on their opposing surfaces, respectively. Both ends of the protected body 5 are fitted into the recesses 8 and 9. The cushioning materials 6 and 7 have exactly the same shape, and as shown in FIG. Engagement convex portions 10 of approximately equal height 1 ₁ ,
11 having a width of 1 ₂ and a length of 1 ₃ , and adjacent to the inside of the convex portions 10 and 11, engaging grooves 12 and 13 having the same length and a depth of 1 ₂ and a width of 1 ₁ are formed on the surface. Form perpendicular to. On the other hand, circumferential pieces 14, 15, 16, 1 that wrap the protected object 5 fitted with the cushioning materials 6, 7 and come into close contact with the circumferential surfaces of the cushioning materials 6, 7.
A frame body 19 made of cardboard or the like is provided, and the front and rear end peripheral side pieces 14 and 1 of the frame body 19 are formed into a band shape.
Cuts 14b, 14b, 18b with a length equal to the width 1 ₂ of the engaging protrusions 10, 11 in a direction parallel to the ends at positions 13/2 from the ends 14a, 18a on both sides of the 8.
18b and make cuts 20, 20, 21, 21 with a length of 12 on both sides of the circumferential surface 16 at _intervals corresponding to the length ₁₃ of the engagement groove 11, and cut 90 degrees along these cuts. Raise the short engagement piece 22, 2
2, 23, 23 and the long engagement pieces 24, 24, and at the same time cut and raise the engagement parts 22a, 22.
a, 23a, 23a, 24a, 24a are formed.

In this way, when packing a product, the protected object 5 is inserted into the recesses 8, 9 of the cushioning materials 6, 7, and the circumferential side of the cushioning materials 6, 7 is surrounded by the band-shaped frame 19. The long engaging pieces 24, 24 of the circumferential piece 16 are fitted into the lower engaging grooves 13, 13 of the members 6, 7, and the lower engaging protrusions 11, 11 are cut and raised on the long engaging pieces 24. After engaging with the rear engaging portions 24a, 24a, the engaging pieces 22, 22, 23, 23 of the circumferential pieces 14, 18
As shown in FIG.
2 and 12 in order to complete the packaging.

According to this packaging device, the thickness ₁₁ of the engaging pieces 22, 23 is approximately equal to the width of the engaging groove 12, and the engaging pieces 22, 23 and the engaging grooves 12, 12 are arranged so that the cushioning material 6,
By forming the engaging pieces 22, 23 in a direction parallel to the outer periphery of the grooves 7, a sufficient length is obtained. It does not come off easily. Further, since the cut and raised portions of the engaging pieces 22, 23, 24 are used as the engaging portions 22a, 23a, 24a and are engaged with the engaging convex portions 10, 10, 11, 11, both sides of the frame 19 Lateral movement is prevented and the packaging becomes very rigid.

In addition, as shown in FIG. 5, the peripheral piece 1 of the frame 19
8 is the length of the circumferential piece 16, and at the same time, long engaging pieces 25, 25, which are the same as the long engaging pieces 24, 24, are provided on both sides, and a tongue piece 26 is formed at the end of the circumferential piece 18, On the other hand, a holding piece 27 having a length shorter than the gap between the cushioning materials 6 and 7 is connected to the circumferential piece 15 in place of the circumferential piece 16, and an insertion hole 28 for the tongue piece 26 is connected to this connecting part.
, and the circumferential side piece 18 may cover the entire upper surface.

As described above, according to the present invention, a pair of cushioning materials are formed with recesses that fit into both ends of an object to be protected, and the surrounding surfaces of the object to be protected and the pair of cushioning materials exposed between the pair of cushioning materials are wound. and a belt-shaped frame body, the frame body is provided with engaging pieces that are erected on the frame body at positions corresponding to at least the upper and lower surfaces of the above-mentioned cushioning material in accordance with the winding direction of the frame body. An engagement groove into which the upright engagement piece fits is formed in the cushioning material at a position corresponding to the engagement piece in the same direction as the engagement piece, and is formed by cutting and raising the engagement groove. An engaging protrusion that fits into the engaging hole formed by cutting and bending the piece is provided on the buffer body at a position corresponding to the engaging hole, so it can be used with corrugated paper etc. without using a box-shaped packing case. A belt-shaped frame consisting of is wrapped around a cushioning material,
The packaging is completed by inserting and engaging the engaging piece and the engaging piece formed after cutting and raising the engaging piece into the engaging groove and the engaging protrusion of the cushioning material, respectively.
In addition to reducing material costs, packaging and dismantling operations can be performed easily.

In this case, the engaging piece is erected so as to coincide with the winding direction of the frame, and the engaging groove is provided in the same direction as the engaging piece, that is, coincident with the winding direction of the frame. Therefore, when inserting and fitting the engagement piece into the engagement groove and wrapping the frame around the buffer body, there is no need to deform the engagement piece and forcefully insert it into the engagement groove. The winding operation is very simple, and it is possible to prevent the inconvenience of deterioration of the strength of the engaging piece due to deformation of the engaging piece.

In addition, the structure is simple because the cut and raised portion of the engagement piece is used as an engagement hole and is engaged with the engagement convex portion of the cushioning material to prevent the frame from moving to both sides. However, the packaging is very strong. In this case, since the frame body is wound around the circumferential side of the buffer body that fits on both ends of the protected object, the direction in which the buffer body tries to come out is perpendicular to the winding direction of the frame body, and as a result, Since the above-mentioned engaging piece and the engaging groove are aligned with the winding direction, the arrangement direction of the engaging piece and the engaging groove into which this engaging piece fits is in the direction in which the cushioning material is about to come out. They will be orthogonal. Therefore, even if the cushioning material tries to come off, the engagement between the engagement piece and the engagement groove, which are arranged perpendicular to the direction in which the cushioning material is trying to come out, firmly prevents the cushioning material from coming off, thereby preventing the packaging from being removed. You can definitely make it work.
