Description

  The present invention relates to a packing structure, and more particularly, to a packing structure that can easily pack packed objects of various shapes and large packed objects.

  For example, when a product is shipped from a factory, it is common to pack the product in a packing box and load it on a vehicle, etc., and transport it. ”) May be damaged. In particular, in the case of electronic equipment and precision equipment, the equipment is easily damaged by slight vibration.

  On the other hand, a buffer member is interposed between the packaging box and the article to be packaged to reduce vibration and impact transmitted to the article to be packaged (Patent Document 3).

  For example, a packaging structure is known in which foamed plastic such as foamed polystyrene or foamed polyethylene is molded into a predetermined shape, and the foamed plastic is fitted to the outside of an article to be packed and placed in a packaging box (Patent Document 1).

  In addition, a packing structure has been proposed in which a pellet-shaped cushioning material is packed between a packing box and an object to be packed.

  In addition, a cardboard grid partition is provided in the foamed plastic or cardboard trunk, the packaged items are stored in a space partitioned by the grid partition, and covered with foamed urethane cushion sheets above and below it. There has been proposed a packaging structure in which binding is performed with a binding band (Patent Document 2).

  However, the packaging structure described in Patent Document 1 requires a mold for manufacturing a foamed plastic cushioning member, which is not only costly, but also bulky, and is difficult to store, and also has a different size and shape. It is necessary to manufacture a cushioning member for each package, and the versatility is poor.

  Further, in the case of a pellet-shaped cushioning material, not only is the disposal difficult, but when the cushioning material is a polystyrene foam, there is a possibility that it will be finely broken and clogged in the holes and gaps in the package.

On the other hand, the packing structure described in Patent Document 2 is suitable for packing a large number of items to be packed having a relatively small shape size, but in the case of a large item to be packed, it is within a space partitioned by a grid-like partition. I couldn't store it.
Moreover, since it is necessary to bind with a binding band each time, packing work is complicated.

  This invention makes it a subject to provide the packing structure which enabled easy packing of the to-be-packaged object of various shapes and a big to-be-packed object in view of this problem.

  Therefore, the packing structure according to the present invention is a packing structure in which an object to be packed is sandwiched between a pair of cushioning members from above and below and pushed into a packaging box for packaging, and the cushioning member is made of a base and a polyurethane foam. A plurality of legs, and the base has a planar shape that can be fitted into a packaging box, and the plurality of legs are erected on the base and are placed on the article to be packed from above or below. Is formed in a shape that can sandwich the side portion of the packaged item between the legs, and when the cushioning member is put on the packaged item from above and below and pushed into the packaging box, When all or a part of the packaged object is in contact with the upper and lower bases, the position of the packaged object in the longitudinal direction in the packaging box is maintained, and the plurality of legs are inwardly formed by the packaging box. Pushed by And by, characterized in that the position of the object to be packed in the cross section of the packing box is adapted to be held.

  One of the features of the present invention resides in that a buffer member is constructed by erecting a plurality of foamed polyurethane legs on the base.

  Thus, when the cushioning member is put on the packaging object from above and below and pushed into the packaging box, all or part of the packaging object is brought into contact with the upper and lower bases in the vertical direction in the packaging box. The position of the object to be packed can be held, and the position of the object to be packed in the transverse section of the packing box can be held by pushing the plurality of legs inward by the packing box.

  As a result, if the base comes into contact with part of the top or bottom surface of the package and the leg comes into contact with part of the side of the package, the package can be packed stably. It is possible to stably pack regardless of the shape and size of the package, and it is not necessary to manufacture a buffer member for each packaged item having a different size or shape as in the packing structure described in Patent Document 1, and is excellent in versatility.

  In addition, since at least the legs are made of foamed polyurethane, there is no troublesome disposal such as pelletized cushioning material, and it is finely crushed like a foamed cushioning member to make holes and There is no risk of clogging the gap.

  Moreover, since it is not necessary to bind with a binding band, the packing work is also easy.

  The base may be made of a material different from that of the legs, but is preferably made of the same foamed polyurethane as the legs, and the legs are fixed to the outer part of the base.

  The base may have the same planar shape as that of the packaging box. However, from the viewpoint of weight reduction and reduction in the amount of raw materials required, the base is formed into a flat wide cross, and legs are attached to the tops of the four wide crosses. It is good to fix.

  Moreover, it is good to form the hole for grasping the handle provided in the top surface of the to-be-packaged object in the center of a base.

  Moreover, said buffer member is also novel. That is, the cushioning member used for packaging according to the present invention includes a foamed polyurethane base and a plurality of foamed polyurethane legs, and the base has a planar shape that can be fitted into a packaging box. The portion is erected on the base, and is formed in a shape that can be placed on the object to be packed from above or below and sandwich the side part of the object to be packed between the plurality of legs. When the whole or a part of the packaged item comes into contact with the upper and lower bases when being covered from above and below and pushed into the packaging box, The position is maintained, and the plurality of legs are pushed inward by the packing box, so that the position of the packaged item in the cross section of the packing box is held. And butterflies.

It is a schematic perspective view which shows preferable embodiment of the packing structure which concerns on this invention. It is a principal part enlarged view in the said embodiment. It is a schematic perspective view which shows the buffer member in the said embodiment. It is a schematic perspective view which shows the buffer member in 2nd Embodiment.

  Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 to 3 show a preferred embodiment of a packaging structure according to the present invention. In the packing structure of this example, the packing box 10 and a pair of buffer members 20 are included.

The packaging box 10 is manufactured in a rectangular box shape using cardboard or the like, and the buffer member 20 is manufactured using foamed polyurethane. This density foamed polyurethane ^{20kg / m 3 ~30kg / m 3} , 25% hardness 90N～200N: having the characteristics within the range of (the measuring method according to JIS K6401) is preferable.

  The buffer member 20 is composed of a wide cross-shaped base 21 and four leg portions 22, and a circular (or other shape) hole 21 </ b> A is formed in the center of the base 21. The provided handle can be grasped from the upper side of the base 21.

  Further, the leg portion 22 is fixed on the four wide cross-shaped top portions of the base 21 by using an adhesive or the like, and both edges of the front end face of the leg portion 22 are rounded so that it can be easily set on the package 30. However, it may be a right angle or an acute angle.

  When packing the article to be packed 30, the cushioning member 20 is covered from both sides in the longitudinal direction of the article to be packed 30 and sandwiched between the leg portions 22 of the cushioning member 20 of the article to be packed 30. In this way, the article 30 to which the cushioning member 20 is set is pushed into the packaging box 10.

  Then, the base 21 of the upper and lower cushioning members 20 and the article 30 to be packed come into contact with each other, whereby the vertical position of the article 30 to be packed in the packing box 10 is maintained, and the four legs of the upper and lower cushioning members 20 are retained. As the portion 22 is pushed inward by the packaging box 10 as indicated by an arrow P in FIG. 1, the four legs 22 and the side surfaces of the packaged object 30 are brought into close contact with each other, and the transverse section of the packaging box 10 is obtained. The position of the article to be packed 30 is maintained, and the article to be packed 30 can be stably packed in the packing box 10.

  When taking out the item to be packed 30 from the packing box 10, a hand is inserted through the circular hole 21 </ b> A of the base 21 of the buffer member 20, and a handle (not shown) provided on the top surface of the item to be packed 30 is held. When pulled, the object to be packed 30 sandwiched between the upper and lower cushioning members 20 can be pulled out from the packing box 10.

  In the above example, for the convenience of manufacturing, as shown in FIG. 3, the base 21 of the buffer member 20 has a structure in which two upper and lower members are fixed, and the leg portion 22 has a structure in which three lateral members are fixed. However, the present invention is not limited to this, and the base 21 and the legs 22 may be manufactured as a single sheet.

  In the above example, the base 21 has a wide cross shape. However, the base 21 may have a rectangular shape, and any shape is acceptable as long as it can be fitted into the packaging box 10.

  Furthermore, the size and thickness of the base 21 and the thickness and length of the legs 22 may be appropriately selected according to the size of the packing box 10 and the size of the article 30 to be packed.
