Description

  The present invention relates to a packing material for packing an object to be packed such as a refrigerator and other electric products, and particularly relates to a packing material provided with a hand hole.

  FIG. 6 shows a conventional packing material disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2001-31065), specifically, a packing procedure using the packing material. According to the disclosure, the packing material covers a carton case (packing case) 3, a cushion member 5 placed on the bottom surface of the carton case 3, and both side surfaces of the package object 1, and the cushion member together with the package object 1. Cushion materials 2 and 2 which are placed on 5 and stored in a carton case 3, and a packing auxiliary sheet 4 which surrounds both side surfaces and the bottom surface of the article 1 from the outside of the cushion materials 2 and 2. I have. The cushion member 5 includes a sheet material 5a and a foamed cushion material 5b. The packing auxiliary sheet 4 includes a bottom surface portion 4d having a cushion material 4e and two side surface portions 4b.

  Both side surfaces of the carton case 3 and the cushion materials 2 have rectangular handle holes (hand holes) 3a and 2a at corresponding positions. Further, the packing auxiliary sheet 4 also has a handle portion (hand hole) 4c on each side surface portion 4b at a position corresponding to the handle hole 3a of the carton case 3 and the handle hole 2a of the cushion material 2. This handle portion 4c is formed by cutting and bending each side surface portion 4b of the packing auxiliary sheet 4 in a U-shape. And at the time of conveyance, it inserts a hand in these hand holes 3a, 4c, and 2a, and enables it to carry a to-be-packaged object safely.

  Another handle hole (hand hole) 4a is further provided at the upper end portion of each side surface portion 4b of the packing auxiliary sheet 4, and when packing or unpacking, a hand is inserted into the handle hole 4a to 1 and the cushion material 2 are lifted.

  FIG. 7 shows another example of a packing material provided with a hand hole. However, this example was obtained in the process of developing the packaging material of the present invention by the inventor of the present application, and is not a known technique, but merely disclosed for the purpose of better understanding of the present invention. This packing material 100 surrounds the periphery of the bottom of the refrigerator R as an object to be packed, supports the bottom surface (with a cushioning material) 102, and the left and right sides of the top surface of the refrigerator R or the edges on both the front and rear sides. A pair of upper cushioning material 103 that is installed and protects the edge and four corners of the refrigerator, and a packing case 104 made of corrugated cardboard that covers the entire surface excluding the lower surface of the refrigerator R are provided. Two opposite side surfaces of the four side surfaces (front and rear surfaces and left and right surfaces) of the packing case 104 are cut in a U-shape along the direction parallel to the direction in which each upper cushioning material 103 extends to make a manual hole. As the forming portion 105, the hand hole forming portion 105 is bent inward (to the refrigerator 101 side) in the same manner as the handle portion 4c shown in FIG. 6, and two hand holes in the shape of the hand hole forming portion 105 are formed. It is supposed to be formed. For reinforcement, a PP tape 106 is attached to the back surface of the packing case 104 immediately above the hand hole forming portion 105. Reference numeral 107 denotes a binding PP band.

JP 2001-31065 A

  As apparent from FIG. 6, the packaging material disclosed in Patent Document 1 includes a carton case (packing case) 3, cushion materials 2 and 2, a cushion member 5, a packing auxiliary sheet 4, and a member with many points. There is a problem that the material cost increases accordingly.

  On the other hand, the packing material 100 shown in FIG. 6 is packed at the hand hole by carrying and unpacking work by inserting a hand into the hole when the packaged item is particularly heavy like a refrigerator. Since the cardboard sheet of the case material is easily broken, there is a problem that a reinforcing material such as PP tape 106 must be provided in the packing case. This is also true for the packing auxiliary sheet 4 in Patent Document 1. In Patent Document 1, a hand is inserted into the handle hole (hand hole) 4a of the auxiliary sheet 4 to lift the article 1 to be packed, which is very heavy. In order to deal with the article 1 to be packaged, it is considered necessary to provide a reinforcing material in the vicinity of the handle hole (hand hole) 4a as in the example shown in FIG.

  Furthermore, in the packing material 100 of FIG. 6, when removing the packing case 104 at the time of unpacking, the upper shock absorbing material 103 moves and drops | disconnects, and there exists a problem that an unpacking operation | work and a repacking operation | work will become complicated easily. is there.

  Accordingly, an object of the present invention is to reinforce PP tape or the like in a packing case having a packing case having a hand hole forming portion that becomes a hand hole by bending inward and a cushioning material disposed inside the packing case. It is an object of the present invention to provide a packaging material that can eliminate the need for a material and can prevent re-packing by preventing the upper cushioning material from falling off during unpacking.

In order to solve the above problems, the present invention provides:
In a packing case having a hand hole forming portion that becomes a hand hole by bending inward, and a packing material provided with a cushioning material disposed inside the packing case,
The cushioning material has a recess on the back surface,
At least a part of the hand hole forming portion has a width that is lower on the lower side than the upper side of the packing case in a state before being bent,
The said hand hole formation part is fitted and fixed to the said recessed part of the back surface of the said buffer material, when it is bent inside.

  In this specification, the term “inside” refers to a direction toward the packaged item in a state where the packing material is attached to the packaged item, and the term “outside” refers to a direction away from the packaged item.

  In the packaging material of the present invention, when forming the hand hole, the hand hole forming part is folded inward and fitted into the recessed part formed on the back surface of the cushioning material, so that the hand hole forming part is formed in the recessed part. Fixed. Thereby, a shock absorbing material is fixed with respect to a packing case. At this time, since the lateral width of the at least part of the hand hole forming portion is expanded and the portion is positioned above the narrower width portion in the concave portion, the hand hole forming portion comes out of the concave portion. This prevents the hand hole forming portion from being fixed to the recess (and hence the buffer material is fixed to the packing case).

  Further, since the cushioning material is in a position close to the hand hole, this cushioning material also functions as a reinforcing material for the packing case. As a result, a dedicated reinforcing material such as PP tape that is necessary for the packing material of FIG. 6 becomes unnecessary.

  Further, since the cushioning material is thicker than the packing case, the bent hand hole forming portion is held by the thick cushioning material. As a result, even a heavy packaged item such as a refrigerator can be transported safely and satisfactorily.

  Further, as described above, since the cushioning material is fixed to the packing case, the cushioning material is prevented from moving and dropping during unpacking work. In addition, after the unpacking operation, the cushioning material remains fixed to the packing case, so that repacking becomes easy.

  In one embodiment, the cushioning material is an upper cushioning material that is attached along the upper edge of the article to be packed.

  In one embodiment, the cushioning member locks the at least part of the hand hole forming portion in the recess to prevent the hand hole forming portion from moving to the outside of the packing case. Has a stop.

  In this configuration, when the hand hole forming portion is bent inwardly, the at least part of the hand hole forming portion (the portion having an expanded lateral width) is locked to the locking portion of the cushioning material. The Therefore, the hand hole forming portion in the recess of the cushioning material is prevented from moving downward and falling off from the recess, and as a result, the hand hole forming portion is stably fixed in the recess of the cushioning material.

  The said latching | locking part can be comprised by the part located between the side surface of the said recessed part, and the lower end surface of the said upper shock absorbing material, for example.

  Moreover, in one Embodiment, the bottom face of the recessed part of the said buffer material inclines so that the depth of the said recessed part may become so deep that it goes to the lower end side of the said buffer material.

  In other words, the concave portion of the cushioning material becomes shallower as it goes upward from the lower end of the cushioning material, and the thickness of the cushioning material above the concave portion can be made comparable to the thickness of the cushioning material other than the concave portion. Therefore, the minimum necessary strength and cushioning action of the cushioning material in the recess are maintained.

  Further, according to the above configuration, when the hand hole forming portion is bent, the hand hole forming portion extends obliquely upward along the bottom surface of the concave portion, and is sandwiched between the article to be packed and the upper cushioning material at the upper side. It becomes a shape. This also makes it possible to fix the hand hole forming portion satisfactorily.

  In one embodiment, the packing material further includes a base on which the packed object is placed, and the packing case has a side facing the base so that the packing object is covered from above. It is open.

  In one embodiment, the cushioning material is made of polystyrene foam, and the packing case is made of a corrugated cardboard sheet.

  In one embodiment, the packing case has two hand hole forming portions on each of two opposing surfaces (front and rear surfaces or left and right side surfaces).

  As is clear from the above, the packing material of the present invention has a lower cushion than the upper side of the packing case before the cushioning material has a recess and at least a part of the hand hole forming portion provided in the packing case is bent. The lateral width is expanded on the side, and the hand hole forming portion is bent so that it can be fitted and fixed to the concave portion of the cushioning material. The cushioning material can be fixed to the packing case by fixing the hand hole forming part in the recess, so that the cushioning material can be prevented from moving and dropping during unpacking, and repacking is also possible. It becomes easy. In addition, since the bent hand hole forming part is held by a cushioning material that is thicker than the packing case, even a heavy packaged item such as a refrigerator can be transported safely and satisfactorily. Can do. Further, since the cushioning material serves as a reinforcing material for the hand holes, the packing case reinforcing material (PP tape or the like) that is required in the conventional packing material can be eliminated.

It is a schematic perspective view of the packing material which concerns on one Embodiment of this invention, Comprising: The use condition immediately after packing the refrigerator as a to-be-packaged item is shown. It is a schematic perspective view which shows the state in which the hand hole formation part of the packing material of FIG. 1 is bent and the hand hole is opened. It is a schematic sectional drawing of the packing material in the state of FIG. It is a perspective view of the upper shock absorbing material contained in the packing material of FIG. It is explanatory drawing which shows the example of the hand hole formation part of a shape different from the hand hole formation part shown in FIG. 2 is a diagram showing a packaging material described in Publication 1. FIG. It is a perspective view which shows the background art for a better understanding of this invention.

  Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

  Drawing 1 is a perspective view of packing material 10 concerning one embodiment of the present invention, and shows the use state just after packing refrigerator R which is an example of a thing to be packed.

  The packing material 10 is installed along the left and right edges of the top surface of the refrigerator R, and a bottom base 12 with a cushioning material (such as polystyrene foam) that surrounds the bottom of the refrigerator R and supports the bottom surface. A pair of upper cushioning members 13 that protect the edges and the four corners, and a packing case 14 that covers the entire surface of the refrigerator R except for the lower surface thereof are provided. In this embodiment, the upper cushioning material 13 is made of foamed polystyrene, and the packing case 14 is made of a cardboard sheet. These materials are merely examples and are not limiting. For example, materials such as foamed polyethylene and foamed polypropylene can be used as appropriate.

  Since the configuration of the base 12 itself is not the subject of the present invention, a detailed description thereof will be omitted here. However, an existing or future developed one that is suitable for the bottom shape of the object to be packed is used as the base 12. Can be used.

  The packing case 14 has four side surfaces (the left and right surfaces 14a and 14b and the front and rear surfaces) that cover the outer periphery of the refrigerator R, and a lid portion 14c that covers the upper surface of the refrigerator, and the lower end is open.

  The packing case 14 has two (a total of four) hand hole forming portions 15 spaced apart in the horizontal direction at the upper part of each of the left and right surfaces 14a and 14b. These hand hole forming portions 15 are formed by cutting a cardboard sheet, which is a material of the packing case 14, into an isosceles trapezoidal shape (excluding a portion corresponding to the upper base), and a portion corresponding to the upper base in the packing case. 14 is bent inside. This isosceles trapezoidal shape is a shape in which the lateral width is expanded on the lower side than the upper side of the packing case 14. The dimension of the hand hole forming portion 15 is, for example, about 90 mm × 30 mm in width, but this is only an example and is not a limited dimension.

  The folding position of each hand hole forming portion 15 corresponds to the position of the lower end of the upper cushioning material 13 placed on the top of the refrigerator R as shown by the broken line in FIG. When the portion 15 is folded inside the packing case 14 along the broken line portion, the hand hole forming portion 15 is fitted and fixed to a recess 135 provided in the upper cushioning material 13 described later, and as shown in FIG. Hole 15a is opened.

  FIG. 3 is a schematic cross-sectional view of FIG. 2 taken along the hand hole 15a. FIG. 4 is a perspective view of the upper cushioning material 13 as viewed from below.

  The configuration of the upper cushioning material 13 will be described. As shown in FIG. 4, the upper cushioning material 13 includes an upper portion 131 that extends in the horizontal direction (front-rear direction) along the upper surface of the refrigerator R, and a side surface (left surface 14a) of the refrigerator R. Or it has the side part 132 extended in a horizontal direction (front-back direction) along the right surface 4b), and the front part 133 and the rear part 134 engaged with the front-back surface of the refrigerator R.

  The dimensions of the upper cushioning material 13 are set according to the weight and dimensions of the packaged material. As an example, the depth dimension of the refrigerator R is 600 mm to 700 mm, and the thickness of the upper cushioning material 13 is about 20 mm. The packing case 14 is much thicker than the cardboard sheet. This thickness is merely an example and is not limiting.

  On the back surface of the side portion 132, a concave portion 135 having a shape in which the shape of the hand hole forming portion 15 (in this example, an isosceles trapezoidal shape) is turned upside down is provided. When the hand hole forming portion 15 is bent, the hand hole forming portion 15 is fitted and fixed to the recess 135. As a result, the upper cushioning material 13 is fixed to the packing case 14. At this time, in the concave portion 135, the portion where the lateral width of the hand hole forming portion 15 is expanded is positioned above the portion where the lateral width is narrower, so the hand hole forming portion 15 comes out of the concave portion 135. This prevents the hand hole forming portion 15 from being fixed to the concave portion 135, and thus the buffer material 13 is fixed to the packing case 14 in a good and stable manner.

  Further, since the lower end portion of the upper cushioning material 13 is located at a position corresponding to the upper end portion of the hand hole 15 a, the upper cushioning material 13 also functions as a reinforcing material for the packing case 14. As a result, in the packaging material 10 of the present embodiment, a dedicated reinforcing material such as PP tape that is required in the packaging material 100 of FIG. 7 is not necessary.

  The depth of the concave portion 135 becomes deeper toward the lower end side of the side portion 132 of the cushioning material 13. In other words, the depth of the concave portion 135 becomes shallower from the lower end surface 132a of the side portion 132 toward the upper portion 131. The bottom surface 135a of 135 is an inclined surface as can be seen from the cross-sectional view of FIG. Therefore, the thickness of the upper cushioning material above the recess 135 can be approximately the same as the thickness of the side 132 of the upper cushioning material other than the recess 135. Therefore, the necessary minimum strength and cushioning action of the upper cushioning material 13 in the recess 135 are maintained.

  Further, since the bottom surface 135a of the concave portion 135 of the upper cushioning material 13 is an inclined surface, when the hand hole forming portion 15 is bent, as shown in FIG. The upper portion of the refrigerator R is sandwiched between the side surface of the refrigerator R and the upper cushioning material 13. This also makes it possible to fix the hand hole forming portion 15 satisfactorily.

  Further, since the thickness of the upper cushioning material 13 is thin at the opening on the lower end side of the recess 135, the hand hole forming portion 15 can be bent smoothly and cleanly (the broken line portion in FIG. 1).

  Further, the side surface 135b of the concave portion 135 and the lower end surface 132a of the side portion 132 intersect with each other at an acute angle, and the portion 136 located between these surfaces functions as a locking portion 136 for the hand hole forming portion 15. That is, when the hand hole forming portion 15 is bent and inserted into the recess 135 of the upper cushioning material 13, the wide portion of the hand hole forming portion 15 contacts the locking portion 136 of the upper cushioning material 13. The formation portion 15 is prevented from moving downward and coming out of the opening at the lower end of the recess 135, and as a result, the hand hole formation portion 15 is stably fixed in the recess 135 of the upper cushioning material 13.

  Next, a standard packing method for the refrigerator R will be described. The refrigerator R covered with a plastic bag is placed on the base 12 and covered with a packing case 14 from the upper side, and then the two upper cushioning materials 13 are attached to the refrigerator R. The packing case 14 is sealed, and finally the base 12 and the packing case 14 are bound by the PP band 17.

  When transporting the refrigerator R packed in this way, the hand hole forming portion 15 is bent as described above and fitted and fixed to the concave portion 135 of the upper cushioning material 13 to form the hand hole 15a. . As described above, since the upper cushioning material 13 is thicker than the packing case 14, the bent hand hole forming portion 15 is favorably held by the thick upper cushioning material 13. Therefore, even the heavy refrigerator R can be transported safely and satisfactorily.

  At the time of unpacking, the PP band 17 is cut, a hand is caught in the hand hole 15a, and the packing case 14 is pulled up. At this time, since the hand hole forming portion 15 remains fitted in the recess 135 of the upper cushioning material 13, the upper cushioning material 13 remains fixed to the packing case 14. A mass retailer or the like has a request for repacking, so the packing case may not be crushed when unpacking. In such a case, since the upper cushioning material 13 is fixed to the packing case 14, the upper cushioning material 13 does not move or drop off during unpacking, and repacking is facilitated.

  In the above description, the shape of the hand hole forming portion 15 is an isosceles trapezoidal shape, but is not limited to this shape. For example, as shown in FIG. 5, various shapes such as a circle or an ellipse excluding the upper arc portion and a combination shape of two rectangles having different widths can be used. In short, it is sufficient that at least a part of the hand hole forming portion 15 has a shape in which the lateral width is expanded below the upper side of the packing case 14 in a state before being bent.

  Further, the packing case 14 has been described as a one-beat type that extends from top to bottom, but may be a two-piece type that is divided into two in the vertical direction.

  In the above description, the upper cushioning material 13 installed on the upper part of the refrigerator R, which is an object to be packed, has been described as an example of the cushioning material. However, the upper cushioning material 13 may be dropped during unpacking. The present invention can be applied to any buffer material.

  Moreover, although the to-be-packaged item was the refrigerator R in said description, the packing material of this invention is applicable also to another electric product.
