Description

  The present invention relates to a cushioning material for packing used to protect a packaged item from an impact or the like when accommodating various items to be packed in a packing box, and particularly when a large impact is applied, It is characterized in that the impact can be sufficiently mitigated to protect the packaged item appropriately.

  Conventionally, various units and cartridges to be used in image forming apparatuses such as copying machines and printers are stored in a packing box made of cardboard and transported or stored. Has been done.

  In order to prevent the packaged items such as various units and cartridges from being stored in the packaging box, the packaged items are prevented from being damaged by the impact of the packaged items. A cushioning material for packing is placed in a packaging box that accommodates the packaging material, and the impact applied to the article to be packed is reduced by the cushioning material for packaging.

  Here, when the cushioning material for packing is arranged in the packing box as described above to reduce the impact applied to the packaged object, the flat portion 1a is generally made of a foam material such as foamed polystyrene as shown in FIG. The packing cushioning material 1 in which ribs 1c are integrally formed on the side wall 1b and the packing material 2 to be accommodated in the packaging box 3 by the packing cushioning material 1 is sandwiched in the vertical direction. The rib 1c provided in the cushioning material 1 is brought into contact with the upper and lower surfaces and the side surfaces of the object to be packed 2, and the lid 3a of the packaging box 3 is closed in this state, and the shock applied to the object to be packed 2 1 is relaxed by the rib 1c provided in the first.

  However, in the case of the packing cushioning material 1 described above, the rib 1c is integrally formed with the flat surface portion 1a and the side wall portion 1b, and the rib 1c is restrained by the flat surface portion 1a and the side wall portion 1b. The height that 1c can expand and contract effectively corresponds to the height of the rib 1c protruding from the flat surface portion 1a and the side wall portion 1b, and the impact applied to the article 2 cannot be sufficiently mitigated. there were.

  In recent years, a cushioning material made of corrugated cardboard or the like is cut, and a foam cushioning material made of foamed material such as foamed polystyrene is cut through the punched hole formed by the cutting. There has been proposed one that is mounted in a hole (for example, see Patent Document 1).

However, when the foam cushioning material made of foam material is attached to the hole formed by the notch provided in the cushioning material composed of cardboard or the like in this way, the foam cushioning material is sufficiently placed at the position of the hole. If the foam cushioning material falls out of the punched hole during packing, or if an impact is applied, the notch expands and the foam cushioning material falls out of the punched hole, or the foam cushioning material is misaligned. Thus, there is a problem that the packaged item cannot be properly held, and the impact applied to the packaged product cannot be sufficiently reduced.

  This invention makes it a subject to solve the above problems in the cushioning material for packing used for protecting a to-be-packaged item from an impact etc., when accommodating various to-be-packaged items in a packing box. Therefore, even when a large impact is applied, it is an object to sufficiently reduce the impact so that the packaged item can be appropriately protected.

In packaging buffer material according to the present invention, in order to solve the problems as described above, only set so as to pass through the mounting holes in the first buffer member made of a foam material, the mounting holes of the first cushioning member so as to penetrate, wider than the second cushioning member on the mounting hole of the second cushioning member is fitted into the mounting hole of the Rutotomoni, said first cushioning member made of a foam material which abut the object to be packed A wide part was formed .

  Moreover, in this cushioning material for packing, it is preferable to form a rib that contacts the surface of the packaged object different from the surface where the second buffering member contacts the packaged object on the first buffering member. .

  In this packing cushioning material, the first cushioning member and the second cushioning member can be made of the same or different foam materials.

  In the cushioning material for packing in the present invention, the first cushioning member and the second cushioning member made of the foam material are used, and the second cushioning member is formed so as to penetrate the mounting hole provided in the first cushioning member. Since the second buffer member is sufficiently held by the first buffer member due to the friction between the first buffer member and the second buffer member in the mounting hole, the first buffer member is sufficiently held in the mounting hole. The second buffer member is prevented from falling off the mounting hole of the first buffer member.

  Moreover, in the cushioning material for packing in the present invention, since the second cushioning member is mounted so as to penetrate the mounting hole of the first cushioning member as described above, the second cushioning member is deformed so as to expand and contract. It is unlikely that the first buffer member suppresses this, and even when a large impact is applied, the second buffer member is appropriately deformed so that the impact applied to the package is sufficiently mitigated. become.

Further, when mounting the second buffer member in the mounting hole so as to penetrate the mounting hole of the first buffer member, a wide portion wider than the second buffer member is formed in the mounting hole. When a compressive force is applied to the second buffer member, the second buffer member is compressed and deformed so as to expand within the wide portion of the attachment hole, and the impact applied to the packaged item is further alleviated.

  Moreover, if the rib which contacts the surface of the to-be-packaged object different from the surface to which said 2nd buffer member contacts the to-be-packaged object is formed in said 1st buffer member, the to-be-packaged object will be in the cushioning material for packing. Shaking is prevented, and the impact in a direction different from that of the second buffer member is also mitigated by the rib.

  Further, when the first cushioning member and the second cushioning member are made of the same foamed material, it is possible to reduce the error in manufacturing both of them and to increase the molding accuracy. On the other hand, when the first buffer member and the second buffer member are made of different foam materials, a foam material having a large elastic deformation is used for the second buffer member so as to further alleviate the impact applied to the object to be packed.

Side wall portions 13 are erected along the side portions, and a plurality of mounting holes 12 (two in the example shown in the figure) are provided in the flat surface portion 11, and the long side wall portion 13 a in the side wall portion 13 is provided. And two short side wall portions 13b opposite to each other are provided with ribs 14 respectively. Moreover, in this embodiment, the wide part 12a which became wide each in the two long side part in said attachment hole 12 is provided.

  On the other hand, as the second buffer member 20 to be mounted so as to penetrate through the mounting hole 12, a recess 21 is formed in the central portion on one long side of the rectangular parallelepiped, as shown in FIG. Is used, and ribs 22 are formed on both sides.

  And in the buffer material for packing in this embodiment, as shown in FIG. 4, said rib 22 provided in the 2nd buffer member 20 is the side wall part 13 from the plane part 11 of said 1st buffer member 10. As shown in FIG. The second buffer member 20 is mounted in each mounting hole 12 so as to pass through the mounting holes 12 provided in the first buffer member 10.

  Thus, when the first buffer member 10 and the second buffer member 20 are made of a foam material, and the second buffer member 20 is attached so as to penetrate the mounting hole 12 provided in the first buffer member 10, The friction between the first buffer member 10 and the second buffer member 20 causes the second buffer member 20 to be held by the first buffer member 10 so as not to be easily removed from the mounting hole 12, and for each mounting. In the wide portion 12 a of the hole 12, a gap is generated between the second buffer member 20 and the wide portion 12 a.

  Then, when the packaging material 2 is accommodated in the packaging box 3 using the packaging cushioning material in which the second cushioning member 20 is mounted in each mounting hole 12 of the first cushioning member 10 as described above, FIG. As shown in FIG. 6, the corner portion of the side wall portion 13 of the first buffer member 10 where the long side wall portion 13 a and the short side wall portion 13 b intersect is positioned at the corner of the packaging box 3. Thus, the pair of packing cushioning materials are arranged at the bottom of the packing box 3.

  Next, the package 2 is placed on each rib 22 of the second cushioning member 20 in the packaging cushioning material arranged in this way, and each of the first cushioning members 10 provided on the side wall portion 13 is placed. The package 2 is held by a pair of cushioning materials disposed on the bottom of the packaging box 3 so that the side surfaces of the package 2 are brought into contact with the ribs 14.

  Thereafter, as shown in FIG. 7, in the state where the packing cushioning material is turned upside down, the rib 22 of the second cushioning member 20 in the packing cushioning material is brought into contact with the upper surface of the package 2. The ribs 14 provided on the side wall 13 of the first cushioning member 10 are placed in contact with the side surfaces of the package 2 so that a pair of packaging cushioning materials are placed over the package 2. In this state, the lid 3a of the packing box 3 is closed.

  In this way, when the article to be packed 2 is accommodated in the packing box 3, the article to be packed is provided by the ribs 14 provided on the side walls 13 of the second buffer member 20 and the first buffer member 10 in each packing cushioning material. 2 is held, and the object to be packed 2 is prevented from rattling.

  Further, as described above, since the second buffer member 20 is mounted so as to penetrate the mounting hole 12 of the first buffer member 10, the second buffer member 20 expands and contracts when an impact force is applied. When the second buffer member 20 is applied with a compressive force, the second buffer member 20 is compressed and attached. When the second shock absorbing member 20 is deformed so as to expand into the wide portion 12a of the hole 12 and a large impact is applied in the vertical direction, the second shock absorbing member 20 is appropriately deformed to apply the impact in the vertical direction applied to the article 2 Will be fully relaxed.

  Further, when a lateral impact is applied, the lateral impact applied to the article to be packed 2 is alleviated by the ribs 14 provided on the side wall portion 13 of the first cushioning member 10 in each packing cushioning material. Become so.

  In the packing cushioning material in this embodiment, the ribs 14 are provided on the side wall 13 of the first cushioning member 10.
