Description

[Detailed Description of the Invention] This invention relates to an annular cushioning body used in combination with an outer box made of cardboard, cardboard, or the like.

Conventionally, this type of buffer has often been made of foamed resin, but this is relatively expensive and difficult to dispose of.

In order to eliminate these drawbacks, this invention was designed to be made of cardboard or thick paper so that it could be reused and to reduce the cost of packaging materials.Hereinafter, one embodiment of the cushioning material of this invention will be explained. do.

That is, Fig. 1 is a developed view of the proposed shock absorber made of a single rectangular corrugated board, etc., and 1.2 and 3.4 are horizontal fold guide lines provided at predetermined intervals along its entire length. These guide wires are bent so as to protrude toward the front in the figure.

5, 6, 7, 8, 9.10 are vertical reverse fold guide lines provided outward from the guide lines 1 and 4, respectively,
In the molded state, it is bent in the opposite direction to the bending direction.

11, 12.13 are cut grooves for winding provided between the guide lines 5-8, 6-9 and 7-10, 14, 1
5, 16.17 are inner walls that are separated by the reverse fold guide lines 5, 6.7 and the fold guide line 4 and form the inner circumferential surface in the state of use described later; similarly, 18.19, 20, 21.22 ,23,2
4, 25, 26, 27, 28.29 are respectively separated by fold guide lines 4, 3, 2.1 and cut grooves 11, 12.13, and 18, 19, 20.21 are the top walls in use. ,
Also, 22.23, 24.25 are the outer walls, and 26, 2
7, 28, and 29 form a bottom wall in a circumferential manner.

The remaining seams 30, 31, 32 and 33 form a series of reinforcing legs a when in use.

To form the proposed shock absorber from the structure shown in FIG. The joints 30, 31, 32, 33 are mechanically fastened or fixed to the inner walls 14, 15, 16, 17, respectively, so that the cylindrical shape does not return to its original shape. They are adhered to form an elongated rolled cylinder A shown in FIG.

Next, from this state, using the above-mentioned cut grooves 11, 12.13, bend the whole body along the reverse fold guide lines 5, 6.7 so as to wrap it toward the front side, as shown in Fig. 3. Form into the annular buffer shown.

Thereafter, the packaged object C is inserted into the inner storage space B of the annular buffer body created in this way, and the opening/closing lids 35, 36, 37, and 38 of the outer box 34 shown in FIG. The packaging is completed by fixing the package with a holder or the like.

Since this device is constructed as described above, there is a cylindrical buffer section reinforced by the reinforcing legs a between the packaged object and the outer box, thereby reliably buffering external shocks. In addition, since it is easy to assemble and disassemble, it does not take up much space for storage, and it can be reused, which has the advantage of reducing packaging costs.

In particular, since the shock absorber of the present invention is formed by bending a single board such as corrugated board or cardboard into a ring shape, it is easy to manufacture and has excellent manufacturing efficiency.

[Brief explanation of drawings]

Figure 1 is a developed view of the shock absorber of this invention, Figure 2 is a perspective view showing the shock absorber in Figure 1 rolled up into a cylinder, and Figure 3 is a view of the shock absorber of this invention.
FIG. 4 is a perspective view showing how to use the cushioning body of this invention. In the figure, A is the rolled-up cylindrical body, a is the reinforcing leg at its tip, 1
1, 12, and 13 are cut grooves provided in the cylindrical body A, and B is a storage space for the packaged body C. In other figures, the same reference numerals indicate the same parts.

Claims (1)

[Scope of utility model registration request] A plurality of cut grooves from the outside extending from the top wall, outer wall, and bottom wall of the wrapped cylindrical body A made of a single plate having the reinforcing leg part a at the rolled end are cut in the longitudinal direction of the cylindrical body A. The packaging is characterized in that the cylindrical body is bent into an annular shape so as to form a storage space B for the packaged object C by providing a predetermined interval along the grooves and forming a storage space B for the packaged object C by the inner wall on the opposite side based on each of these grooves. Annular buffer for use.
