Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

FIG. 2 is a perspective view showing an embodiment of the present invention. The packing member 30 which is a packing box is composed of an outer box 1 and a packing 2. The packing member is made of a corrugated cardboard material, and in the embodiment of the present invention, the surface in contact with the floor is the bottom surface 1a and the surface facing the floor is based on the state where the outer box 1 as shown in FIG. 2 is placed on the floor. Two surfaces located perpendicular to the top surface 1b, the bottom surface 1a, and the top surface 1b are referred to as the side surface 1c.

The flap formed at the opening side end of the packing space 3 formed by these surfaces shall be bent inward of the packing space 3 for packing. At this time, the flap formed on the bottom surface 1a is the inner flap 11, the flap formed on the top surface 1b is the outer flap 12, the flap formed on the side surface 1c is the side flap 13, and the two side flaps 13 are first used. After bending inward of the packing space 3, the inner flap 11 and the outer flap 12 are bent in the same order, and the outer flap 12 and the bottom surface 1a are fixed with tape or the like to close the opening on one side of the packing space 3.

The packing 2 is inserted into the packing space 3 with the product 50 attached to the surface 2a and the vertical wall surface 2b described later bent, and the flaps on the opposite sides are closed in the same order as described above, and the outer flap 12 and the packing 2 are inserted. Products can be packed by fixing the bottom surface 1a with tape or the like.

When the purchaser takes out the product together with the packing 2 from the outer box 1, the purchaser can take out the product from the outer box 1 by pulling the round hole-shaped handle 2d formed on the end 2c side of the surface 2a of the packing 2. You can.

FIGS. 3A and 3B show how the tensile force acts due to the difference in the shape of the handle hole. When the force acting when the handle is pulled is P, the force acts on the stress concentration points at both ends of the conventional oval-shaped handle hole. When the same force is applied to the round hole-shaped handle of the present invention, the tensile force is dispersed according to the number of round holes (3), so that the force acting on the stress concentration portion can be reduced, resulting in damage to the material. Can be reduced.

FIG. 4 shows a developed view of the packing 2. Folded lines 2e are simultaneously formed at both ends of the packing 2 by a punching process at the time of manufacturing a part, and the standing wall surface 2b is formed by bending the end portions from this as a starting point.

As shown in FIG. 5, the vertical wall surface 2b functions as a support of the packing space 3 when the packing 2 is inserted into the outer box 1, and is oriented toward the bottom surface 1a when the product is stored in a warehouse or the like in the packed state, for example. It plays a role of increasing the strength when the outer boxes 1 are stacked. In FIG. 5, the flap of the outer box is removed for the sake of explanation.

At this time, it is desirable that the direction of the core 2f of the corrugated cardboard forming the packing 2 is perpendicular to the folding line 2e of the vertical wall surface 2b because it is stronger against compression.

Further, the packing 2 can be smoothly inserted into the outer box 1 by providing a gap of about 3 mm between the upper end 2g of the vertical wall surface 2b and the top surface 14 on the packing space side of the top surface 1b of the outer box 1. Can be done.

As described above, the shape of the packing 2 is produced by punching the material, but when the round hole portion of the round hole-shaped handle 2d is formed, the cutting blade is waved as shown in FIG. By using the blade, when the purchaser pulls out the product from the outer box 1 by using the round hole-shaped handle 2d, it is possible to prevent the cut end portion 2h of the cardboard material from being cut.

The round hole-shaped handle 2d in the present invention is not limited to the application to the packing 2 which is a packing member, and as shown in FIGS. 7 and 8, the top surface 1b and the side surface 1c of the outer box 1 and the like, etc. Needless to say, the same effect can be obtained even if it is formed on the wall surface of.

FIG. 7 is an example in which the present invention is used on the top surface 1b of the outer box 1. By inserting the product into the outer box 1 with the same specifications as described above, closing the flaps, and then holding the round hole-shaped handle 1d formed on the outer flap 12 side of the top surface 1b, a conventional oval-shaped hole handle is provided. For the same reason as packing 2, it can be made harder to tear. This can be applied to the side surface 1c as well.

FIG. 8 shows an example in which the present invention is used for the outer flap 12 of the outer box 1. When the outer flap 12 is provided with the round hole-shaped handle 1e and the present invention is applied, the inner flap 11 facing the outer flap 12 in the packed state is the same as or has a round hole facing the round hole-shaped handle 1e. By providing the hole 1f slightly larger than the shaped handle 1e, the purchaser can insert a finger when using the round hole shaped handle 1e.

Further, as shown in FIG. 9, when forming a hole for a handle, 1 g of a handle having a round hole shape can be obtained by processing a part of the hole into a perforation, and the purchaser can break through to form the handle shape. Can be done. As a result, it is possible to prevent dust from entering the packing box, and by folding the half-pulled shape 1h of the round hole-shaped handle 1g into the packing space 3, the cardboard of the handle part overlaps and the strength is strengthened. Can be done (see FIG. 10).

In the present embodiment, the number of round hole-shaped handles 2d, 1d, and 1e is shown as three, but the force for taking out the packing 2 and the outer box 1 is dispersed as the number of holes increases, and the cardboard is used. The number of round hole-shaped handles 2d, 1d, and 1e is not limited because the tearing of the handle can be prevented.

Further, the number of round hole-shaped handles 2d, 1d, and 1e installed is mainly shown in one place. For example, the round hole-shaped handles 1e provided on the outer flap 12 are also on the opposite outer flap 12. good.
