Description

  The present invention relates to a packaging material, and more particularly to a packaging material having a configuration used when transporting a packaging material.

  As a conventional packaging material, a packaging material including a box-shaped outer packaging material made of cardboard and a cushioning material provided at the bottom of the outer packaging material has been proposed (for example, see Patent Document 1). A handle for inserting a hand when transporting the packing material is formed at a lower portion of the outer peripheral surface of the outer packaging material. This handle has a square shape with rounded corners.

  Here, an example in which the object to be packed is a refrigerator will be described. Generally, the width in the left-right direction of the front of the refrigerator and the width in the left-right direction of the back of the refrigerator are shorter than the width of the lateral side of the refrigerator, that is, the width in the depth direction of the refrigerator. Therefore, when the transportation space is limited, for example, when passing through a corridor, the carrier faces the front or back of the refrigerator toward the floor of the corridor and the side surface of the refrigerator toward the wall of the corridor. May be transported. Thereby, it can be avoided that the packing material comes into contact with the wall surface of the corridor. In addition, if the transport space is easily secured, the transporter may transport the refrigerator with the side surface of the refrigerator facing the floor. As described above, the transporter may change the attitude of the packing material according to the transport location.

  The packing material described in Patent Literature 1 is provided with a plurality of handles. However, the longitudinal direction of each handle is the same. Therefore, when the carrier changes the attitude of the packing material, the carrier holds a place other than the handle, for example, a corner of the packing material. If the carrier holds the corners of the packing material, there is a possibility that when the carrier places the packing material on the floor surface, his / her finger may be pinched between the floor surfaces. Therefore, in addition to the first handle of the packing material described in Patent Document 1, a means for further forming a second handle having a longitudinal direction different from the longitudinal direction of the first handle on the packing material may be considered. However, when the first handle and the second handle are formed on the packing material, the distance between the first handle and the second handle decreases as the distance from the first handle to the second handle decreases. The width of the corrugated cardboard becomes smaller. In other words, the means for separately forming the second handle may cause a portion where the width of the cardboard is small, and the means for separately forming the second handle has a problem that the strength of the packing material is reduced.

  The present invention has been made to solve the above-described problems, and has as its object to provide a packing material capable of suppressing a decrease in strength.

  The packing material according to the present invention is provided with a plate-shaped member made of cardboard and having a handle freely formed in a first range and a second range different from the first range. A first linear notch extending from the start end to the first end, a second linear notch extending from the start end to the second end, and a linear first notch extending from the start end to the third end; 3 is formed, and a first cut portion and a second cut portion are formed on the periphery of the first range, and the first cut portion and the second cut portion are formed on the periphery of the second range. A notch and a third notch are formed.

  According to the present invention, the first cut portion is formed on the periphery of the first range and the periphery of the second range. That is, the first range and the second range are provided with the first cut portion therebetween. For this reason, according to the present invention, it is possible to suppress a decrease in the strength of the packaging material.

<Operation of First Embodiment>
FIG. 8 is a perspective view showing a state where the plate member 21 is bent at the bending portion 31. The transporter can form the opening Op1 in the plate member 6A by bending the plate material 21 at the bending portion 31. The carrier can hold the packing material 100 by inserting a finger into the opening Op1. In this manner, the carrier can form a handle on the packing material 100 by bending the plate material 21 at the bending portion 31. In addition, when the transporter inserts his / her finger into the opening Op <b> 1 to transport the packing material 100, the transporter's finger is in contact with not only the bent portion 31 but also the plate 21. At this time, the plate 21 is in contact with the handle surface sf2. Therefore, when the transporter transports the packaging material 100 by inserting his / her finger into the opening Op1, the load of the packaging material 100 is reduced by the bending portion 31, that is, the plate-shaped member 6A, the handle surface sf2, that is, the cushioning material 6C1, Disperse in.

  FIG. 9 is a perspective view illustrating a state in which the plate member 22 is bent at the bending portion 32. The transporter can form the opening Op2 in the plate member 6A by bending the plate member 22 at the bending portion 32. The carrier can insert his / her finger into the opening Op2. In this manner, the transporter can form a handle on the packing material 100 by bending the plate material 22 at the bending portion 32. Further, when the transporter inserts his / her finger into the opening Op <b> 2 to transport the packing material 100, the transporter's finger is in contact with not only the bent portion 32 but also the plate 22. At this time, the plate member 22 is in contact with the handle surface sf1. For this reason, when the transporter transports the packaging material 100 by inserting his / her fingers into the opening Op2, the load of the packaging material 100 is reduced by the bent portion 32, that is, the plate-shaped member 6A, the handle surface sf1, that is, the cushioning material 6C1, Disperse in.

  FIG. 10 is a perspective view showing a state where the plate material 21 and the plate material 22 are bent. The carrier may bend the plate 21 at the bent portion 31 and the plate 22 at the bent portion 32. In the state shown in FIG. 10, two handles are formed on the packing material 100.

  FIG. 11 schematically shows a state where the packing material 100 is being carried by the carriers hm1 and hm2. FIG. 12 is an explanatory diagram of the holding position of the carrier hm1 in the state shown in FIG. As shown in FIG. 11, the height from the floor to the center of gravity of the packing material 100 is H1, and the height from the floor to the cuts 10A and 10B is h1. The carrier hm1 holds the lower part of the packing material 100 by forming handles in the cut portions 10A and 10B. In the state shown in FIG. 12, an opening Op1 is formed in the cut portion 10A. The carrier hm2 holds the upper part of the packing material 100. Here, the frame member 6B1 is shorter than the frame member 6B2. The frame member 6B1 is located on the front side of the refrigerator, and the frame member 6B2 is located on the lateral side of the refrigerator. In FIG. 12, since the frame member 6B1 is located above the frame members 6B2 and 6B4, the rear surface of the refrigerator faces the floor in the state shown in FIG. In the state shown in FIG. 12, it is easy to secure the space between the frame member 6B2 and the wall Wa and the space between the frame member 6B4 and the wall Wa.

  In the state shown in FIG. 11 and FIG. 12, the notch 8A and the notch 8B are located below the notch 10A and the notch 10B, and the carrier hm1 has the notch 8A and the notch 8B. It is difficult for fingers to reach the notch 8B. Therefore, in the state shown in FIGS. 11 and 12, if the carrier hm1 holds the handles of the cut portions 8A and the cut portions 8B, the burden on the carrier hm1 may increase. For this reason, the carrier hm1 holds the handles of the cut portions 10A and 10B.

  FIG. 13 is an explanatory diagram of a holding position different from FIG. In FIG. 13, the carrier hm1 forms a handle at the cut 9A and the cut 10A to hold the lower part of the packing material 100. In the state shown in FIG. 13, an opening Op2 is formed in the cut portion 10A. Although not shown, the carrier hm2 holds the upper part of the packing material 100 as in FIG. In the state shown in FIG. 13, the lateral side of the refrigerator faces the floor. Since the plate-shaped member 6A can freely form both the opening Op1 and the opening Op2, the transporter can hold the packing material 100 in the posture shown in FIG. 12 or the packing material 100 in the posture shown in FIG. Can also be held.

  FIG. 14 schematically illustrates a state in which the packing material 100 is transported by the transporters hm1 and hm2 in a state where the location of the transporter hm2 is lower than the location of the transporter hm1. Is shown. FIG. 15 is an explanatory diagram of the holding position of the carrier hm1 in the state shown in FIG. It is assumed that the carriers hm1 and hm2 have shifted from the state shown in FIG. 11 to the state shown in FIG. In addition, as shown in FIG. 14, the height from the floor surface to the center of gravity of the packing material 100 is H2 higher than H1. The height from the floor to the cut 8A and the cut 8B is h2, which is approximately the same as h1, and the height from the floor to the cut 10A and the cut 10B is higher than h1. h3.

  As shown in FIG. 14, the carrier hm2 is climbing the truck bed. In this state, the height position of the carrier hm2 is higher than the height position of the carrier hm1. Therefore, when the carrier hm2 tries to hold the packing material 100 on the truck bed while maintaining the angle θ1 of the packing material 100 shown in FIG. For this reason, as shown in FIG. 14, the carrier hm1 and the carrier hm2 are raising the packing material 100. As a result, the angle θ2 of the packing material 100 is steeper than the angle θ1 of the packing material 100 shown in FIG.

  Further, since the height of the center of gravity of the packing material 100 has increased from H1 to H2, the height of the cut portions 10A and 10B has increased from h1 to h3. For this reason, if the carrier hm1 is holding the handles of the notch 10A and the notch 10B, the carrier hm1 must hold the packing material 100 with the upper arm raised upward, The load of hm1 increases. Therefore, the carrier hm1 does not hold the handles of the cut portions 10A and 10B, but holds the cut portions 8A and 8B. That is, the carrier hm1 changes the handle when shifting from the state illustrated in FIG. 11 to the state illustrated in FIG.

<Effect of First Embodiment>
Cut portions 11 are formed on the periphery of the range Rg1 and the periphery of the range Rg2. That is, the range Rg1 and the range Rg2 are provided with the notch 11 therebetween. Therefore, in the packing material 100, there is no strip-shaped cardboard between the periphery of the range Rg1 and the periphery of the range Rg2. If the range Rg1 and the range Rg2 are not provided with the cut portion 11 therebetween and the range Rg1 and the range Rg2 are separated from each other, a belt-like shape is formed between the periphery of the range Rg1 and the periphery of the range Rg2. Of cardboard may be present. The shorter the distance between the periphery of the range Rg1 and the periphery of the range Rg2, the narrower the band-shaped cardboard becomes. Such a strip of corrugated cardboard causes a reduction in the strength of the packing material due to its thinness. In the first embodiment, since the range Rg1 and the range Rg2 are provided with the cut portion 11 therebetween, it is possible to avoid the occurrence of such a strip of corrugated cardboard. Accordingly, while the packing material 100 includes the handle structure for realizing the posture in which the rear surface of the refrigerator shown in FIG. 12 faces the floor surface and the handle structure for realizing the posture in which the lateral side surface of the refrigerator shown in FIG. 13 faces the floor surface, The packing material 100 has no strip-shaped corrugated cardboard, and a reduction in strength is suppressed.

  In the state before the handle is formed on the packing material 100, the opening Op1 is not formed in the range Rg1, and the opening Op2 is not formed in the range Rg2. Therefore, before the handle is formed on the packing material 100, insects and dust hardly enter the packing material 100.

  The cut portion 11 and the cut portion 13 are orthogonal to each other at the position P2. Therefore, it is possible to prevent the opening area of the opening Op1 and the opening area of the opening Op2 from becoming narrow. For this reason, the carrier can reliably insert his / her fingers through the openings Op1 and Op2. The cuts 12 and 13 are orthogonal to each other at the position P2. Here, if the cut portion 12 and the cut portion 13 form an obtuse angle, the opening area of the opening Op1 becomes small. If the cut 12 and the cut 13 form an acute angle, the portion of the plate-shaped member 6A sandwiched between the cut 12 and the cut 13 becomes thin. As a result, the strength of the plate-shaped member 6A may be reduced. Since the cut portion 12 and the cut portion 13 are orthogonal to each other at the position P2, the packing material 100 can avoid a reduction in the opening area of the opening Op1, and the packing material 100 is formed of the plate-like member 6A. The decrease in strength is suppressed.

  The plate-shaped member 6A includes a bent portion 31 serving as a bent portion of the plate material 21 and a bent portion 32 serving as a bent portion of the plate material 22. For this reason, even if the carrier bends the plate material 21 at the bent portion 31, the plate material 21 does not come off from the plate-like member 6 </ b> A. Can't come off. For this reason, it can be avoided that the plate material 21 and the plate material 22 drop on the floor surface and the floor surface is scattered.

  The effect of the cut portion 10A has been described so far. Here, the notch 10B has the same configuration as the notch 10A. Therefore, the cut portion 10B can obtain the same effect as the effect of the cut portion 10A described above.

  The packing material 100 includes a cushioning material 6C1 provided with a handle surface sf1 and a handle surface sf2. As shown in FIG. 8, when the carrier inserts his / her finger into the opening Op1 and holds the packing material 100, the plate 21 and the holding surface sf2 are in contact. For this reason, when the carrier inserts his / her finger into the opening Op1 and holds the packing material 100, the load of the packing material 100 is applied to the bent portion 31, that is, the plate-shaped member 6A, and the handle surface sf2, that is, the cushioning material 6C1. Spread. Here, when the handle surface sf2 of the cushioning material 6C1 is not formed, the load of the packing material 100 is supported only by the bent portion 31, that is, the plate-shaped member 6A. Therefore, depending on the weight of the article to be packed, the plate-shaped member 6A may be broken when the carrier holds the packing material 100. Further, a means for arranging reinforcing wood having the function of the holding surface sf2 on the plate-like member 6A is also conceivable. However, in this means, since the reinforcing wood is arranged in addition to the cushioning material 6C1, not only the manufacturing cost increases, but also the amount of waste when the packing material is discarded increases. In the first embodiment, since the packing material 100 includes the cushioning material 6C1 provided with the handle surface sf1 and the handle surface sf2, the plate member 6A is broken, and the manufacturing cost is increased. An increase in waste can be suppressed. Since the cushioning member 6C2 has the same configuration as that of the cushioning member 6C1, the same effects as those of the cushioning member 6C1 described above can be obtained.

  As shown in FIG. 3, the first divided range D1 includes a range Rg1, a range Rg2, and a range Rg3. Further, the distance from the range Rg3 to the first edge 6A1 is longer than the distance from the range Rg1 to the first edge 6A1. The carrier can form a handle in both the range Rg1 and the range Rg3. When transporting the packaging material 100 in the state as shown in FIG. 11, the transporter can have a handle in the range Rg1, and when transporting the packaging material 100 in the state as shown in FIG. It can have a handle in the range Rg3. As described above, the carrier can adjust the position of the handle of the packing material 100 in the vertical direction, so that the work load on the carrier when holding the packing material 100 is suppressed. Here, the effects of the cut portions 10A and the cut portions 8A have been described. The notch 10B has the same configuration as the notch 10A, and the notch 8B also has the same configuration as the notch 8A. Therefore, the same effect can be obtained for the cut portions 10B and the cut portions 8B.
