Description

[Detailed explanation of the idea] This invention relates to a packaging box with cushioning material.

In a packaging box with a cushioning material inside, the cushioning material and the packaging box are usually separate bodies, and when the package is opened and the stored item is taken out, the cushioning material falls apart.

For this reason, when using such packaging boxes to re-storage an item that has been taken out, cushioning material is fitted to both ends of the item and this is inserted into the packaging box. It is difficult to know the direction to attach the material, and if the item is not fitted into the recess of the cushioning material without any gaps, the cushioning material gets stuck on the upper edge of the box opening, making it difficult to insert.

The purpose of this invention is to eliminate the above-mentioned drawbacks.

That is, this invention allows for easy packaging by using the cushioning material provided at both ends of the stored article and the cylindrical box, and also enables the cushioning material and the cylindrical box to be opened as a unit and easily resealed. It is a packaging box with cushioning material.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

The packaging box with cushioning material of this invention consists of a rectangular packaging base material 1 made of thick paper such as cardboard, which is folded to form a cylindrical box body, as shown in the developed view in Fig. 1; As shown, a cylindrical box body 22 (formed using the packaging base material 1) is fitted to both ends of a stored article 21 (see FIGS. 5 and 6).
(See Figure 4) should not be combined with a pair of prismatic cushioning materials 2 made of foamed polystyrene or the like that close the openings at both ends.

The packaging base material 1 has a side wall 4 serving as a separation portion, a top wall 5, a side wall 6 serving as a hinge portion, a bottom wall 7, and an adhesive piece 8 connected from the end via a fold line 3.

The side wall 4 serving as the separation portion is provided with a separation line 10 that is a perforation or a cut in the longitudinal direction of the center and has a tongue portion 9, and a linear separation line 11 that runs along this separation line 10. .

Further, the side wall 6 serving as the hinge part is provided with a fold line 12 in the central longitudinal direction that serves as an axis when opening and closing.

Note that the separation portion of the packaging base material 1 is not limited to the separation line 10.11.

As shown in FIGS. 2 and 3, the cushioning material 2 is provided with a recess 13 into which the end of the stored article 21 is fitted,
A notch 15 corresponding to the tear line 10 of the packaging base material 1 and dividing this end into upper and lower parts is provided from the inside at one end, and a thin connecting edge 14 whose outer circumferential surface can be cut is also provided at the other end and side. A transverse notch 15' is provided to divide this portion into upper and lower parts from the inside, leaving .

In addition, a plurality of thin connecting edges 14 are provided in the middle of this cut 15'.
By providing ``, the article 21 will not break even if some force is applied when fitting it in, and the shape stability will be improved.

When packaging a stored article 21 in this packaging box with cushioning material, a pair of cushioning materials 2 are fitted to both ends of the article 21, as shown in FIGS. Place the cushioning material 2 on the top surface of the bottom wall 7 in the longitudinal direction of the material 1, and fold the side wall 6, top wall 5, and side wall 4 along the bending line 3.
At the same time, the contact surface is bonded with adhesive 16 (see Fig. 5), and the adhesive piece 8 is attached to the cushioning material 2, and the end wall 4 is attached on top of it, as shown in Fig. 4. So, the packaging is completed.

At this time, the tear line 1 of the packaging base material 1 is inserted into the notch 15 of the cushioning material 2.
It is necessary to wrap the wires so that the zeros match.

This packaging box with cushioning material can be automatically bonded on each contact surface using a hot melt method using an automatic packaging machine.

Further, this packaging box is sealed because the peripheral surface of the cushioning material 2 is adhered to the cylindrical box body with an adhesive without any gaps, and the outer surface of the cushioning material 2 has a thin connecting edge.

The packaging box with cushioning material according to this invention has the above-mentioned configuration, and when it is opened and reused, the cylindrical box body 2
By tearing the two separation lines 10 and 11 of 2, peeling off the piece of paper between them, inserting a piece of metal plate etc. into the notch 15 and cutting the thin connecting edge 14, 14', as shown in FIG. The material 2 is divided into upper and lower parts, and a side wall 6 serves as a hinge part.
The lower box body 23 and the upper lid body 2 are centered around the polygonal line 12 of
4 are rotatably connected.

In this packaging box, when the lid 24 is closed, when the tongue piece 9 of the side wall 4 is inserted inside the adhesive piece 8 of the box body 23, the lid 24 becomes difficult to open due to the frictional force of the contact surface.

In addition, in the case of a packaging box that does not have a separation edge on the side wall 4 on the opening side, the side wall 4 may be cut open using a knife, or the packaging box may be opened by peeling off the adhesive piece 8.

As described above, in the packaging box with cushioning material according to this invention, the cylindrical box body and the cushioning material provided with the cross-cutting cut are glued together when packaging the product, and the cross-cutting cut is used when opening the package. The container can be divided horizontally into a body with an upper opening and a lid, so that it is possible to easily store items again, and it can also be used for a long period of time as a container in which items can be taken out and put in repeatedly. There are advantages.

In addition, since the notches provided in the cushioning material do not reach the outside, the cushioning material is in a sealed state and can block out lumps and moisture.
