Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cushioning material for packaging, and particularly to a cushioning material for packaging that is filled between an outer box and an object to provide a cushioning effect.

When packaging items with complex shapes, items that require precise and careful cushioning packaging, high-mix, low-volume production items, and general individual items that are indiscriminate, we use shapes that suit each item. It is difficult to prepare a cushioning body for this purpose, so a large number of cushioning bodies are used that are randomly packed between the outer box and the packaged item to provide a cushioning effect. Conventional cushioning bodies of this type have the disadvantage that they have poor cushioning properties because they are entirely uniform solid or spongy molded bodies.

This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and by using a molded body made of a cushioning material so as to have a concave portion from the outer peripheral surface toward the inside, the cushioning capacity can be improved. The purpose of the present invention is to provide a cushioning material for packaging that is excellent and has a wide range of applications.

The cushioning body for packaging of the present invention is formed by integrally forming four parts from the outer circumferential surface of a molded body made of a cushioning material toward the inside. The molded body has a diameter that is smaller than the distance between the outer packaging box and the packaged object, and its shape can be spherical, polyhedral, or other shapes. The four parts can be formed by holes or notch-shaped recesses formed from the outer circumferential surface toward the inside, and these can penetrate to the opposite side or extend halfway, and the number is not limited, but it can be formed by a plurality of holes. It is desirable to provide it so that it is uniformly distributed.

Embodiments of the present invention will be described below with reference to the drawings.

Figure 1 (N, Figure 2 (A) and Figures 3 to 6 are perspective views showing packaging cushioning bodies according to different embodiments of the present invention, Figure 1 CB) is Figure 1 (A). ), and FIG. 2(B) is a plan view of FIG. It is molded from a resilient cushioning material such as foamed plastic, rubber, paper, etc. (3) is a recess that is integrally formed almost uniformly from the outer circumferential surface of the molded body toward the inside.

In the embodiment shown in FIG. 1, the molded body (

A plurality of planes symmetrical to the half-cut plane Z, here 8
It consists of approximately semi-cylindrical notch-shaped recesses.

In the embodiment shown in FIG. 3, the molded body (
2) consists of a sphere. The recess (3) is provided parallel to and axially symmetrical to the central axis Y from the opposing outer circumferential surfaces, and
It consists of a plurality of cylindrical through holes, four in this case, that penetrate through the outer peripheral surface on the opposite side.

In the embodiment shown in FIG. 4, the molded body (
2) consists of a sphere. The recesses (3) are formed from a plurality of, in this case four, approximately semi-cylindrical notch-shaped recesses that are provided parallel to and axially symmetrical with the central axis Y from the opposing outer peripheral surfaces and penetrate through the opposite outer peripheral surface.

In the embodiment shown in FIG. 5, the molded body (
2) is a polyhedron, for example, the 0 concave part (3) made of a cube is
It consists of a plurality of, in this case four, cylindrical-shaped through holes that are provided parallel to and axially symmetrical with the central axis Y from the opposing outer circumferential surfaces of one surface, and that penetrate through the opposite outer circumferential surface.

In the embodiment shown in FIG. 6, the molded body (
2) consists of a polyhedron, for example a cube. The fourth part (3) is provided parallel to and axially symmetrically with the central axis Y from the opposing outer peripheral surfaces of the pair of surfaces, and the half-cut surface is set so that the tip is separated by a predetermined distance from the half-cut surface Z perpendicular to the central axis Y. It consists of a plurality of cylindrical holes, eight in this case, formed symmetrically with respect to Z.

As shown in Fig. 7, the buffer bodies (1) constructed as described above are arranged in large numbers at random between the outer box (4) made of cardboard or wood, etc., and the packaged object (5). It is packed and used as a cushioning material for packaging. In this case, a certain amount of buffer material (1
), place the packaged item (5) at an appropriate position in the outer box (4), then pack another cushioning body (1) from above the packaged item (5), and then Exterior box (4)
The ceiling lid (6) is closed and the packaging process is completed through the sealing process.

In such a packaging state, the cushioning bodies (1) packed in the outer box (4) are in proper contact with each other and are not torn apart (
4) and the object to be packaged (5), and the recess (
3), a space is formed in the contact area between the spherical body and the polyhedron that are the molded body (2), so air is present in these spaces, and it has a high buffering capacity. . In other words, the shock absorption effect is carried out from the buffer (1) to the next shock absorber (1) via the air in the gap between the recess (3) and the molded body (2), or from the shock absorber (1) to the next shock absorber (1). ) directly to the next shock absorber (1), and for example, when the package collides with the floor, the shock absorbing action is performed in the above order.

In this way, the shock absorber (1) acts as a shock absorber against external forces, and in addition to the shock absorbing capacity of the shock absorber (1) itself, continuous buffer capacity and buffer capacity due to large air resistance are added, resulting in a high level of shock absorption. will have the ability.

Since the cushioning body (11) is made of a resilient cushioning material such as foamed plastic, rubber, or paper, the density, dimensions, shape, etc. of the cushioning body (1) can be freely changed in view of the material properties. It is possible to change the specifications and characteristics of the buffer depending on the packaging application.

Figures 8 to 10 are perspective views showing different usage patterns, and Figure 8 shows a flat bag formed of a plastic film, etc. (a large number of cushioning bodies (1) are randomly inserted in the direction). This shows an example in which the cushioning body (1) is sealed in a cylindrical shape with a heat-shrinkable plastic film (8), etc. All examples are shown in which a single pack-like shock absorber is used. Fig. 10 shows a case in which a shock absorber (
1) is enclosed to form a single pack-like buffer.

The pack-shaped cushioning body formed as described above is inserted as it is between the outer box (4) and the object to be packaged (5), and is used as a packaging cushioning material. Such a ξ-shaped cushioning body is designed so that the density and dimensions of the cushioning body (1) itself are sufficient to withstand heavy loads, and the bags (7), t9) and film (8) are designed to withstand heavy loads sufficiently. In terms of material and dimensions,
It can be used as a cushioning material for packaging heavy objects such as plants.

In the above embodiments, a sphere or a polyhedron is shown as an example of the molded body (2), but it may be of other shapes. Furthermore, although 4 to 8 cylindrical holes or approximately semi-cylindrical cutout-like recesses are formed as the recesses (3), the shape, structure, number, position, etc. of the recesses can be changed. ) is not limited to the above-mentioned method, and may be changed, and there are no restrictions on the packaging object.

As explained above, according to the present invention, the cushioning body is constituted by a molded body formed from a cushioning material so as to have a concave portion from the outer peripheral surface toward the inside. It is possible to freely change the shape, etc., and can be used as a buffer for packages of any complicated shape, and has a wide range of applications. The buffering effect of the air interposed within the buffer body and the air interposed between the buffer bodies work together effectively, resulting in a large buffering effect. In addition, since the buffer body can be integrally formed by molding, it can be mass-produced and can be provided at a low price.
