Description

  The present invention relates to a cushioning material for packing that protects a product from an impact received by the packing box interposed between the product and the packing box when various products are packed in the packing box. It is designed to maintain the merchantability of the product appearance.

  Conventionally, when various products such as electrical products and electronic products produced in factories are shipped, the products are packed in a cardboard box (packing box), but the impact received when the product is fixed, transported and stored in the cardboard box. A cushioning material is used for the buffering. Synthetic resin, foamed resin, paper, and the like are used as the material of the buffer material, but recently, in order to promote recycling of the used paper, a buffer material formed by pulp molding using the used paper as a material may be used.

  FIG. 6 shows an example of a conventional packing form, and the front surface of an electric product P (DVD player in FIG. 6) covered with a protective sheet F in a concave portion 1a of a packing material 1 made of pulp mold made into a concave shape. The P1 side is accommodated, and the rear surface P2 side of the electric product P is accommodated in the recess 2a of the other packing cushioning material 2. In this state, the electric product P and the packing cushioning materials 1, 2 are placed inside the packaging box B. Pack in Ba.

  As shown in FIG. 7A, the packing cushioning material 1 covering the front surface P1 side of the electric product P has a large number of upper ribs 1b, lower ribs 1c, side ribs 1f and the like protruding toward the recesses 1a. The tips of the ribs 1b, 1c, and 1f are brought into contact with the peripheral surface of the electric product P to hold the electric product P, and the electric product P is buffered against the load and impact received from the white arrow direction shown in the figure.

  In recent electric products P, a part of the outer peripheral surface is mirror-finished or a label is attached to a part of the outer peripheral surface in order to improve the merchantability. For example, in the electrical product P shown in FIG. 6, the top surface portion P3b excluding the top surface portion P3a of the front panel is mirror-finished in the top surface P3, and the label S is placed so as to straddle the top surface portion P3a and the top surface portion P3b. Paste.

  On the other hand, the packing cushioning material 1 that covers the front surface P1 side of the electric product P has a mirror-finished top surface 1g of the top surface P3 of the electric product P, as shown in FIGS. It comes into surface contact with the surface 3b and the label S affixed to the top surface. Therefore, when the packaging boxes B are stacked, a vertical load (load F1 shown in FIG. 7A) is applied to the packaging box B located below, and the top surface portion 3b and the label S are strongly pressed against the upper rib 1b. It becomes a state. As a result, the contact surface of the upper rib 1b remains on the mirror-finished top surface portion 3b, and the label S is wrinkled, resulting in a problem that the merchantability in the appearance of the electric product P is deteriorated. Occur.

  Further, when the packing cushioning material 1 receives an impact F2 from the lateral direction shown in FIG. 7A during transportation, the side wall portion 1f of the packing cushioning material 1 is moved into the inner side as shown in FIG. 7B. As a result, the load associated with the impact F2 is concentrated on the side rib 1e and the vicinity of the end of the side rib 1 falls down, so that it is difficult to sufficiently protect the electrical product P. There is. Further, when the packing cushioning material 1 receives an impact F3 at the lower corner 1d shown in FIG. 7A, the corner 1d is greatly bent and deformed inward as shown in FIG. 7C. As a result, the load accompanying the impact F3 is concentrated on the side rib 1e and the lower rib 1c, the vicinity of the tip of the side rib 1e is tilted upward, and the tip of the lower rib 1c is tilted to the right. The problem arises that it is difficult to protect.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a packing cushioning material in which the appearance of an object to be packed is not adversely affected by a vertical load received from above.
Another object of the present invention is to provide a packing cushioning material that can sufficiently protect an object to be packed by preventing a load from being concentrated on each rib even when the side and the corner are subjected to an impact. And

  In order to solve the above-mentioned problem, the cushioning material for packing according to the present invention is formed in a concave shape so as to cover the periphery of the end of the hexahedral object to be packed, and has ribs that are in surface contact with the top surface of the object to be packed. In the packing material made of pulp mold provided inside the concave shape, the rib is characterized in that a concave portion is provided on the end side of the surface in surface contact.

  Moreover, the cushioning material for packing according to the present invention is formed in a concave shape so as to cover the periphery of the end portion of the hexahedral object to be packed, and in the cushioning material for packing made of pulp mold, It is characterized by comprising diagonal ribs that project from the inward corners in the concave shape facing diagonally toward the corners of the object to be packed.

Furthermore, the cushioning material for packing according to the present invention is formed in a concave shape so as to cover the periphery of the end portion of the hexahedral object to be packed, and is provided with a rib having a rib in surface contact with the top surface of the object to be packed. In the packing material for packing made of a mold, the rib is provided with a concave portion on the end side of the surface that comes into surface contact, and the packaged item is formed from the inner corner of the concave shape diagonally opposed to the corner of the packaged item. It is characterized by providing a diagonal rib which protrudes toward the corner of the.
Furthermore, the packing cushioning material according to the present invention is characterized in that a plurality of recesses are formed in the rib.

  In the present invention, the rib that comes into contact with the end surface of the packaged object is provided with a recess on the end side of the surface in contact with the surface, so that it faces the location where the recess is provided when a vertical load is applied in the packed state. A load is not applied to the portion of the top surface to be applied through the rib. Therefore, if a recess is provided on the end side of the rib front end surface corresponding to a location where the load is not desired on the top surface of the packaged portion (for example, a mirror-finished location or a location where a label is applied), It is possible to avoid deterioration of the merchantability of the appearance of things.

  Moreover, in this invention, the diagonal rib which protrudes diagonally toward the corner | angular part of a to-be-packaged object is provided from the inward corner part of the packing cushioning material diagonally opposed to the corner | angular part of a to-be-packaged object. Therefore, when the impact is applied to the side and when the impact is applied to the corner, the load accompanying the impact is also applied to the diagonal rib, so the load is distributed and received by multiple ribs including the diagonal rib. It is possible to reduce the load on the packed object and improve the protection against the packed object.

In addition, in this invention, when both the rib provided with the recessed part and the diagonal rib are provided, while the deterioration of the merchantability of the appearance of a to-be-packaged object can be avoided, the protection property to the to-be-packaged object can be improved.
Furthermore, in the present invention, by providing a plurality of recesses, it becomes possible to set a plurality of places where no load is applied to the top surface of the portion to be packed, and to-be-packaged items having various forms of top surfaces Can be protected from vertical loads.

In the present invention, since the rib that contacts the end surface of the packaged object has a recess in the surface that contacts the top surface of the packaged object, a vertical load is not applied to the top surface portion facing the recess, It can prevent that the external appearance of the top | upper surface location facing a recessed part deteriorates.
Further, in the present invention, diagonal ribs that project obliquely from the inner corner of the packing cushioning material toward the corner of the article to be packed are provided, so that the impact on the side and the corner is affected. The load can be received by the diagonal ribs to disperse and absorb the load, and the load on the package can be reduced to improve the protection of the package.

In addition, in this invention, when both the rib provided with the recessed part and the diagonal rib are provided, while deterioration of the external appearance of a to-be-packaged object can be prevented, the protection property of the to-be-packaged object with respect to an impact can be improved.
Furthermore, in the present invention, by providing a plurality of recesses, it is possible to prevent a load from being applied to a plurality of locations on the top surface of the packed portion, and even if the top surface has various appearances, the influence of the vertical load Can be avoided.
