Description

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

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

Japanese Unexamined Patent Publication No. 2005-154007

Here, an example in which the packaged object is a refrigerator will be described. Generally, the width of the front of the refrigerator in the left-right direction and the width of the back of the refrigerator in the left-right direction are shorter than the width of the side surface of the refrigerator, that is, the width in the depth direction of the refrigerator. Therefore, when the transport space is limited, for example, when passing through a corridor, the transporter has the front or back of the refrigerator facing the floor of the corridor and the side surface of the refrigerator facing the wall of the corridor. May be transported by. As a result, it is possible to prevent the packing material from coming into contact with the wall surface of the corridor. Further, if the transport space is easily secured, the transporter may transport the refrigerator with the side surface facing the floor. In this way, the carrier may change the posture of the packing material depending on the transport location.

The packaging material described in Patent Document 1 is provided with a plurality of handles. However, the longitudinal direction of each handle is the same. Therefore, when the carrier changes the posture of the packing material, the carrier holds a place other than the handle, for example, a corner portion of the packing material. If the carrier holds the corners of the packing material, the carrier may pinch his fingers on the floor when placing the packing material on the floor. 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 into the packing material can be considered. However, when the first handle and the second handle are formed on the packing material, the closer the distance from the first handle to the second handle is, the more the position is between the first handle and the second handle. The width of the corrugated cardboard is reduced. That is, the means for separately forming the second handle may generate a portion having a small width of the corrugated cardboard, and the means for separately forming the second handle has a problem that the strength of the packing material is lowered.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a packaging material capable of suppressing a decrease in strength.

The packaging material according to the present invention includes a plate-shaped member made of corrugated cardboard and having a handle that can be freely formed in a first range and a second range different from the first range. A linear first notch extending from the start end to the first end, a linear second notch extending from the start end to the second end, and a linear first notch extending from the start end to the third end. A cut portion of 3 is formed, a first cut portion and a second cut portion are formed on the peripheral edge of the first range, and a first cut portion is formed on the peripheral edge of the second range. A cut portion and a third cut portion are formed, and the plate-shaped member is located on a straight line connecting the start end of the first cut portion and the first end of the first cut portion. A fourth bent portion is provided .

According to the present invention, a first notch is formed on the peripheral edge of the first range and the peripheral edge of the second range. That is, the first range and the second range are provided so as to separate the first cut portion. Therefore, according to the present invention, it is possible to suppress a decrease in the strength of the packaging material.

<Operation of the first embodiment>
FIG. 8 is a perspective view showing a state in which the plate member 21 is bent at the bent portion 31. The carrier can form the opening Op1 in the plate-shaped member 6A by bending the plate member 21 at the bent portion 31. The carrier can hold the packing material 100 by inserting a finger into the opening Op1. In this way, the carrier can form a handle on the packing material 100 by bending the plate material 21 at the bent portion 31. Further, when the transporter inserts his / her fingers into the opening Op1 to transport the packing material 100, the transporter's fingers are in contact with not only the bent portion 31 but also the plate material 21. At this time, the plate member 21 and the handle surface sf2 are in contact with each other. Therefore, when the carrier inserts a finger into the opening Op1 and conveys the packing material 100, the load of the packing material 100 is 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 showing a state in which the plate member 22 is bent by the bent portion 32. The carrier can form the opening Op2 in the plate-shaped member 6A by bending the plate material 22 at the bent portion 32. The carrier can insert a finger into the opening Op2. In this way, the carrier can form a handle on the packing material 100 by bending the plate material 22 at the bent portion 32. Further, when the transporter inserts his / her fingers into the opening Op2 to transport the packing material 100, the transporter's fingers are in contact with not only the bent portion 32 but also the plate material 22. At this time, the plate member 22 and the handle surface sf1 are in contact with each other. Therefore, when the carrier inserts a finger into the opening Op2 and conveys the packing material 100, the load of the packing material 100 is the bending 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 in which the plate material 21 and the plate material 22 are bent. The carrier may bend the plate material 21 at the bent portion 31 and bend the plate material 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 in which the packing material 100 is being conveyed by the carrier hm1 and the carrier hm2. FIG. 12 is an explanatory view of the handle position of the carrier hm1 in the state shown in FIG. As shown in FIG. 11, the height from the floor surface to the center of gravity of the packing material 100 is H1, and the height from the floor surface to the cut portion 10A and the cut portion 10B is h1. The carrier hm1 forms a handle on the cut portion 10A and the cut portion 10B to hold the lower portion of the packing material 100. 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. Further, the frame member 6B1 is located on the front side of the refrigerator, and the frame member 6B2 is located on the lateral side surface side of the refrigerator. Since the frame member 6B1 is located above the frame member 6B2 and the frame member 6B4 in FIG. 12, the back 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 distance between the frame member 6B2 and the wall Wa and the distance between the frame member 6B4 and the wall Wa.

Further, in the state shown in FIGS. 11 and 12, the cut portion 8A and the cut portion 8B are located below the cut portion 10A and the cut portion 10B, and the carrier hm1 has the cut portion 8A and the cut portion 8B. It is difficult for fingers to reach the notch 8B. Therefore, in the states shown in FIGS. 11 and 12, if the transporter hm1 holds the handles of the cut portion 8A and the cut portion 8B, the load on the legs and waist of the transporter hm1 may increase. Therefore, the carrier hm1 holds the handles of the cut portion 10A and the cut portion 10B.

FIG. 13 is an explanatory view of a handle position different from that of FIG. In FIG. 13, the carrier hm1 forms a handle on the cut portion 9A and the cut portion 10A to hold the lower portion 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 surface of the refrigerator faces the floor surface. Since both the opening Op1 and the opening Op2 can be freely formed in the plate-shaped member 6A, the carrier can hold the packing material 100 in the posture shown in FIG. 12, and the packing material 100 can be held in the posture shown in FIG. Can also be retained.

FIG. 14 schematically shows a state in which the packing material 100 is being transported by the carrier hm1 and the carrier hm2 in a state where the place where the carrier hm2 is standing is lower than the place where the carrier hm1 is standing. Is shown. FIG. 15 is an explanatory view of the handle position of the carrier hm1 in the state shown in FIG. It is assumed that the carrier hm1 and the carrier hm2 have shifted from the state shown in FIG. 11 to the state shown in FIG. As shown in FIG. 14, the height from the floor surface to the center of gravity of the packing material 100 is H2, which is higher than H1. Further, the height from the floor surface to the cut portion 8A and the cut portion 8B is h2, which is about the same as h1, and the height from the floor surface to the cut portion 10A and the cut portion 10B is higher than h1. It is 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 loading platform of the truck while maintaining the angle θ1 of the packing material 100 shown in FIG. 11, it is necessary to bend down. Therefore, as shown in FIG. 14, the carrier hm1 and the carrier hm2 raise 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 heights of the cut portion 10A and the cut portion 10B have increased from h1 to h3. Therefore, when the carrier hm1 holds the handles of the cut portion 10A and the cut portion 10B, the carrier hm1 must hold the packing material 100 with the upper arm pulled upward, and the carrier hm1 must hold the packing material 100. The burden on hm1 will increase. Therefore, the carrier hm1 does not hold the handles of the cut portion 10A and the cut portion 10B, but holds the cut portion 8A and the cut portion 8B. That is, the carrier hm1 changes the handle when shifting from the state shown in FIG. 11 to the state shown in FIG.

<Effect of Embodiment 1>
A cut portion 11 is formed on the peripheral edge of the range Rg1 and the peripheral edge of the range Rg2. That is, the range Rg1 and the range Rg2 are provided so as to separate the cut portion 11. Therefore, in the packing material 100, there is no band-shaped corrugated cardboard between the peripheral edge of the range Rg1 and the peripheral edge of the range Rg2. If the range Rg1 and the range Rg2 are not provided so as to separate the cut portion 11, and the range Rg1 and the range Rg2 are separated from each other, a band shape is formed between the peripheral edge of the range Rg1 and the peripheral edge of the range Rg2. Cardboard can be present. The closer the distance between the peripheral edge of the range Rg1 and the peripheral edge of the range Rg2 is, the thinner the band-shaped corrugated cardboard becomes. Since such a strip-shaped corrugated cardboard is thin, the strength of the packaging material is lowered. In the first embodiment, since the range Rg1 and the range Rg2 are provided so as to separate the cut portion 11, it is possible to avoid the occurrence of such a strip-shaped corrugated cardboard. Therefore, the packing material 100 has a handle structure that realizes a posture in which the back surface of the refrigerator shown in FIG. 12 faces the floor surface and a handle structure that realizes a posture in which the lateral side surface of the refrigerator shown in FIG. 13 faces the floor surface. The packing material 100 does not have a strip-shaped corrugated cardboard, and the decrease in strength is suppressed.

In the state before forming the handle 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, in the state before the handle is formed on the packing material 100, insects and dust are unlikely to enter the inside of 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 avoid narrowing the opening area of the opening Op1 and the opening area of the opening Op2. Therefore, the carrier can reliably insert the fingers through the openings Op1 and Op2. Further, the cut portion 12 and the cut portion 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. Further, if the cut portion 12 and the cut portion 13 form an acute angle, the portion of the plate-shaped member 6A sandwiched between the cut portion 12 and the cut portion 13 becomes thin. As a result, the strength of the plate-shaped member 6A may decrease. Since the cut portion 12 and the cut portion 13 are orthogonal to each other at the position P2, the packing material 100 can prevent the opening area of the opening Op1 from becoming small, and the packing material 100 is the plate-shaped member 6A. The decrease in strength is suppressed.

The plate-shaped member 6A includes a bent portion 31 which is a bent portion of the plate member 21 and a bent portion 32 which is a bent portion of the plate member 22. Therefore, 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-shaped member 6A, and even if the carrier bends the plate material 22 at the bent portion 32, the plate material 22 is separated from the plate-shaped member 6A. It won't come off. Therefore, it is possible to prevent the plate material 21 and the plate material 22 from falling on the floor surface and cluttering the floor surface.

Up to this point, the effect of the cut portion 10A has been described. Here, the cut portion 10B also has the same configuration as the cut portion 10A. Therefore, the cut portion 10B can obtain the same effect as the effect of the cut portion 10A described so far.

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 a finger into the opening Op1 and holds the packing material 100, the plate material 21 and the handle surface sf2 are in contact with each other. Therefore, when the carrier inserts a 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. scatter. 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 packaged object, the plate-shaped member 6A may be torn when the carrier holds the packaging material 100. Further, a means for arranging the reinforcing wood having the function of the handle surface sf2 on the plate-shaped 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 waste when disposing of the packing material 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-shaped member 6A is torn and the manufacturing cost is increased. It is possible to suppress the increase of waste. Since the cushioning material 6C2 has the same configuration as the cushioning material 6C1, it is possible to obtain the same effect as the effect of the cushioning material 6C1 described here.

As shown in FIG. 3, the first division range D1 includes a range Rg1, a range Rg2, and a range Rg3. Further, the distance from the range Rg3 to the first edge portion 6A1 is longer than the distance from the range Rg1 to the first edge portion 6A1. The carrier can form handles in both the range Rg1 and the range Rg3. When transporting the packing material 100 in the state shown in FIG. 11, the transporter can have a handle in the range Rg1, and when transporting the packing material 100 in the state shown in FIG. 14, the transporter can hold the handle. It can have a handle in the range Rg3. In this way, since the carrier can adjust the position of the handle of the packing material 100 in the vertical direction, the work load of the carrier when holding the packing material 100 is suppressed. Here, the effects of the cut portion 10A and the cut portion 8A have been described. The notch portion 10B also has the same configuration as the notch portion 10A, and the notch portion 8B also has the same configuration as the notch portion 8A. Therefore, the same effect can be obtained for the cut portion 10B and the cut portion 8B.
