Description

[Detailed description of the invention] [Industrial application field] This invention relates to containers, and more specifically, it is a container with a cushion function in which unevenness and double walls are formed on the member constituting the container itself in order to package fragile items. The present invention relates to packaging containers.

[Prior Art] When a large quantity of articles such as computer-related parts or LSIs (Large-Scale Integrated Circuit Devices) are packaged in containers made of natural or synthetic materials, the stored articles and the containers and the housed articles are separated from each other. In order to prevent scratches and impact caused by direct contact, cushion materials were used, such as rice husks, sponges, soft synthetic resin film ribbons, pulp, and synthetic resin plates with textured surfaces.

[Problem that the invention aims to solve] However, since these cushion materials are made separately from the container or are made from natural materials, they must be placed together with fragile items in the container for transportation. The protection effect depends on the management of the cushion material and the way the cushion material is placed.Moreover, when unpacking, it is necessary to dispose of both the cushion material and the container.Especially in the case of a large number of independent cushion materials, it is necessary to dispose of both the cushion material and the container at the unpacking site. It was messy and a problem.

[Purpose of the invention] In order to eliminate the above-mentioned drawbacks, this invention provides a packaging container that can absorb shocks applied from the outside by forming unevenness and double walls on the members constituting the transportation container for packaging fragile items. The purpose is to

[Summary of the invention] In order to achieve the above-mentioned purpose, the packaging container of this invention has an inner plate formed of a continuous curved surface erected around the periphery of a bottom plate having a large number of concave portions or uneven portions. An outer plate, which is integrally formed above and formed with a continuous curved surface on the outside of the inner plate, is suspended so as to form a gap between the outer plate and the inner plate, and an outer plate is formed on the edge of the outer plate. The inner box of the container is formed with a protruding flange, the side plate is provided on the periphery of the top plate with many recesses or irregularities, and one of the opposing side edges is provided with a flat bulge, which is bent inward. and an outer box of the container, which constitutes a locking piece.

[Configuration of the embodiment of the invention] The container inner box 1 constituting the packaging container of this invention is
As shown in Figures 1a and b, a large number of squares and rectangles are made of thermoplastic resin such as vinyl chloride or polyethylene and are formed by well-known vacuum or pressure forming means, protruding outward in an orderly manner in each width direction. On the periphery of the bottom plate 2 in which the recess 3 is formed, a corrugated inner plate 4 formed by a curved surface 5 that is continuously curved inward except for the corners is erected and tilted outward so that the opening side widens. , the upper end of the inner plate 4 is extended horizontally to form a flat edge 6, and the outer edge of the inner plate 4 is extended downwardly and outwardly at a pitch approximately 1/2 of the pitch of the curved surface. A corrugated outer plate 7 formed by a curved surface 8 is suspended slightly below the bottom surface of the recess 3 so that its lower end side expands outward, and the entire lower end of the outer plate 7 is made to extend horizontally. This is how the tsuba 9 is constructed. Note that 10 in the figure is a gap formed between the inner plate 4 and the outer plate 7.

As shown in FIGS. 2a and 2b, the container outer box 11 is
Using thermoplastic resin such as vinyl chloride or polyethylene as raw material, a plurality of square and rectangular convex portions 13 are neatly formed in the center at regular intervals in the longitudinal direction using well-known vacuum or pressure forming means. A side plate 14 is hung down from the periphery of the top plate 12 that protrudes toward the opening side, and a tsuba 16 is provided at all ends of the side plate 14 to extend outward horizontally.
The end portion of 6 is extended to be at least twice the width of the flange,
A locking piece 17 is provided by bending this extended portion on the inside.

The packaging container 20 of this invention consists of the inner box 1 and the outer box 11 constructed as described above, and an example of the use of this container will now be described.

First, a large number of fragile articles or LSI devices, for example, are placed in the recess 18 surrounded by the inner and outer plates 4 and 7 of the inner box 1, and then the inner box 1 is placed in the form of a material as shown in FIGS. 3 to 5. The locking pieces 17 of the outer box 11 can be expanded outward using the elasticity of the outer box 11 and the inner box 1 can be placed in the recess 19 of the outer box 11. The inner box 1 and the outer box 11 will be in a locked state unless the force applied to expand them to the outside is removed.

Note that the locking pieces 17 of the outer box 11 are not bent in advance, and after the article is stored in the inner box 1 and the outer box 11 is covered with the inner box 1, the locking pieces 17 are bent inward to close the outer box 11. It may be possible to prevent removal.

As shown in FIGS. 3, 4, and 5, the side plates that are subjected to external forces during transportation are triple-layered side plates 4,
7 and 14, and between the inner and outer plates 4 and 7,
Due to the presence of the void 10, the side plates can sufficiently absorb external forces applied from the horizontal direction and external forces applied from the vertical direction, and can withstand external forces.
External forces locally applied to the two parts are absorbed by the convex portions 13 and the concave portions 3, and the fragile articles contained therein can be sufficiently protected.

In addition, the recess 3 formed in the bottom plate 2 and the top plate 12
In the embodiment, the convex portions 13 and 13 are both in a state of protruding outward, but the convex portions 13 of the bottom plate 2 are conversely protruded into the concave portions 18 so as to fit with the convex portions 13 of the top plate 12. , convenient for stacking. Further, this invention can be implemented in any planar shape depending on the stored items, such as circular or oval.

[Effects of the invention] As described above, this invention consists of erecting an inner plate formed of a continuous curved surface on the periphery of a bottom plate having a large number of concave portions or uneven portions, and forming an integral part above the inner plate. A container in which an outer plate similarly formed with a continuous curved surface is suspended on the outside of the inner plate so as to form a gap between the inner plate and a flange that protrudes outward is formed on the edge of the outer plate. A side plate is provided on the periphery of the inner box, a top plate formed with numerous recesses or uneven parts, and a flat bulge is provided on one of the opposing side edges,
It is constructed with an outer container box that is folded inward to form a locking piece, so it is useful for transporting and storing fragile items, can be mass-produced at low cost, and can be packaged easily on assembly lines. Large quantities can be automatically packaged, and after an item is placed in the packaging container, the inner and outer boxes are locked, and no members are required for locking, and the packaging material and cushion material are integrated, making it easy to open the packaging. This has advantages such as easy installation work.
