Description

[Detailed description of the invention] The present invention relates to a packaging device devised to simplify the packaging work of mechanical parts such as records or wheels, and other various articles, and relates to a flexible long sheet with appropriate cushioning properties. is bent in an accordion shape that meandered vertically so that the packaged items can be stored between the meandering sheets from between each upper bent portion.In particular, in order to maintain the meandering state of a long sheet, the upper and lower bent portions are bent in a meandering accordion shape. The device is characterized in that a rigid core is provided at both ends of the tube to restrict bending.

Next, embodiments of the present invention will be described based on the drawings.

1 is a box-shaped outer body, which is a paper box such as a cardboard box;
It consists of wooden boxes, plastic resin boxes, and other forms that can be used as outer boxes or frames for packaging, and is mainly rectangular in plan and side.

Reference numeral 2 denotes a long sheet made of a flexible material having appropriate cushioning properties, which is bent up and down inside the outer body 1 and bent in an accordion shape extending laterally to form a section of each upper bent portion 2a. The object to be packaged 10 is placed between the sheets meandering between the sheets.
It is designed to store.

The elongated sheet 2 has rigid cores 3.degree. 3 attached to both ends of each meandering portion 2' between the upper and lower bent portions 2a and 2b so as to restrict bending.

As the cores 3, 3, in addition to wires and thin rods, materials made of synthetic resin rods, narrow plate-like bodies, or other rigid materials can be used.

In particular, those having appropriate elasticity are preferably used.

Moreover, each bent portion 2a is continuous in the longitudinal direction of the sheet and serves as a core at both end portions.

It is also possible to use one in which the portion corresponding to 2b is made bendable.

As a means for attaching the layers 3, 3, bag portions 4, 4 are formed by folding back as shown in the figure at both ends of the long sheet 2, and each layer 3, 3 is inserted into the bag portions 4°4. In addition to the mounting structure, various mounting structures can be used.

Furthermore, in addition to the case where the elongated sheet 2 is detachably attached to the outer body 1, the long sheet 2 can be attached to the side of the outer body 1 by connecting the center of both ends of each meandering portion 2' to which the cores 3, 3 are attached. 5, 5 can be slidably connected and equipped in the sheet extending direction.

In either case, the elongated sheet 2 can be pushed to one end when not in use, and it becomes easier to accommodate the size of the object to be packaged 10.

Of course, both ends of each meandering portion 2' may be connected to the outer body 1 so as to maintain the elongated sheet 2 at a predetermined meandering pitch.

Note that the meandering amplitude (height), pitch, etc. of the elongated sheet 2 may be set according to the height, thickness, etc. of the object to be packaged 10, and the total length of the sheet is also determined by this.

Further, the width of the elongated sheet 2 is usually set to be approximately the same as or slightly smaller than the inner width of the outer body 1.

Materials for the long sheet 2 include sheets of olefin resin foams such as polyethylene, polypropylene, and copolymers thereof, polyvinyl chloride resin foams, and other flexible synthetic resin foams, especially crosslinked olefin resin foams. A sheet of resin foam is preferably used, but it can also be carried out using fabrics such as non-woven fabrics or woven fabrics, or other flexible materials with appropriate cushioning properties and a certain degree of thickness.

The packaging device according to the present invention is used, for example, to package mechanical parts such as records or wheels, and other mainly disc-shaped articles for shipping and transportation. Since the outer body 1 is equipped with a flexible elongated sheet 2 having an appropriate cushioning property and bent in an accordion shape meandering up and down, the article to be packaged, that is, the object to be packaged 10, is By simply inserting and storing the sheet 2 between the meandering upper bent portions 2a and 2b of the shaped sheet 2, each item 10 to be packaged can be reliably and easily packaged with a cushioning sheet interposed between them. .

In particular, the long sheet 2 has upper and lower bent portions 2a, 2b.
Since rigid cores 3, 3 are attached to both ends of each meandering part 2' between the two, even if the sheet material is flexible, the meandering amplitude (height) etc. will not be disturbed and the prescribed value will be maintained. The meandering state can be maintained reliably, and it is easy to store the object 10 to be packaged.

Moreover, it is easy to construct the elongated sheet 2 in an accordion-like manner so that it can be expanded and contracted. This makes the storage work even easier.

Moreover, since the long sheet 2 has flexibility, even if the cores 3 are attached to both ends, the center part can easily follow the object to be packaged, and in particular, it is possible to accommodate objects with slightly different thicknesses. become.

In the packaged state, each packaged item 10 is placed on the lower bent portion 2b of the long sheet 2, and a meandering sheet is always interposed between each packaged item 10, In particular, it becomes a double interposed state, and moreover, the cores 3 and 3
are attached only to both ends and not to the central part where the object to be packaged 10 comes into contact, so it can exhibit an extremely excellent cushioning and protection effect for the object to be packaged, and protect the surface of the object to be packaged. There is no risk of injury.

Of course, the entire exterior can be protected by the box-shaped outer body 1, and a packaging form that can withstand handling during shipping and transportation can be obtained.

As described above, the present invention eliminates the need to interpose cushioning materials between each packaged item or to wrap the packaged items in a sheet in advance when packaging mechanical parts such as records and wheels, as well as various other items. This method greatly simplifies the boxing and packaging work, provides reliable cushioning protection for the packaged items, and has a simple structure, especially since the long sheet is bent like an accordion due to the presence of a core. Easy,
It can be easily manufactured and provided at low cost, and packaging costs can be reduced.
