[Prior art]

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a packaging box and a packaging box sheet for packaging a welding wire and the like, and more particularly, to a packaging box and a packaging box sheet having improved transportability.

The welding wire is wound in a cylindrical shape around the coil core, and the welding wire is a rectangular parallelepiped corrugated paper during the period from the manufacturing factory to the storage, shipping, transport and delivery to the consumer. It is stored in a box.

In other words, the welding wire wound around the coil core is transported in a state of being housed in a corrugated cardboard having a rectangular parallelepiped shape. However, this weld wire is a considerable weight, for example 20 kg wound once. If this heavy object is housed in a cardboard box 11 cm high, for example 28 cm in angle, the worker shall first tilt the cardboard box in which the welding wire is packed, when transporting the welded wire between the bottom of the edge and the floor. First, one hand is inserted, and then the other hand is inserted between the bottom and the bottom of the other edge, and after the two hands are inserted, the cardboard box is lifted and moved to a predetermined position.

However, it is not easy to lift such a heavy thing in an unstable posture, and the transportation is heavy labor.

As a result, when the worker lifts the product, it is easy to cause an accident that the product slips from the hand and falls on the foot when the waist is injured or transported.

In particular, the worker usually wears gloves, so the cardboard box made of paper is slippery, and if carelessly handled, the product falls on the foot and there is a risk of foot injury.

Moreover, by setting a pair of cutting lines parallel to one ridge of a box to the center of this ridge, and setting the cutting lines which connect the ends of each cutting line to each other, the packing box which provided the recessed part in the center of the said ridgeline is proposed. (Japanese Patent Laid-Open No. 3-14449).

The box can be transported by hand to this recess. However, since this recess is formed by cutting a part of the box, there is a difficulty in that the strength is weak. In addition, since the hole is opened in the box while the recess is provided, the packaging is incomplete.

Overview of the Invention

SUMMARY OF THE INVENTION An object of the present invention is to provide a packaging box which can easily lift a cardboard box in which heavy objects are stored, and eliminates the risk of falling.

A packaging box consisting of substantially six sides according to the present invention has at least one concave portion provided at a corner where three ridges are gathered, and each concave portion is bent inward by three cut lines connecting the ridge lines to each other. have.

In a substantially six-sided packaging box according to the present invention, at least one corner portion where three ridges are gathered, three cut lines connecting the ridge lines to each other are provided so that the corner portions can be bent inward.

The packaging sheet for assembling into a packaging box composed of substantially six sides according to the present invention has three cutouts connecting the lines of the ridges to each other at a portion of at least one corner where three ridges are collected. It is.

In the present invention, a recess is formed by at least two corner portions of four corner portions of a box having a rectangular parallelepiped shape, and three cut lines connecting three ridges gathered at each corner portion. For this reason, since this recessed part is formed without setting a cutting line, it is high in strength and does not impair packaging quality.

What is necessary is just to set at least 1 this recessed part. A finger can be inserted between this recess and the bottom surface to lift and tilt one side of the box, and the box can be lifted by placing a hand between the gaps formed on the other side. Therefore, in the present invention, the number of recesses is one, two, three,... Any of eight may be acceptable.

Preferably, however, if two recesses are set on the bottom surface of the packing box, the user can lift the box by inserting fingers into the recesses using both hands once. The worker can then lift the box with this recess. The lifting part is easy for the worker because the recess is easy to hold. In addition, since the concave portion is carried and transported, the conveyance work is easy without the hand slipping from the box.

When the recess is set on both the top and bottom surfaces of the packaging box, even when the packaging box is placed in the opposite state once during the packaging, the ease of lifting the box remains unchanged.

In addition, a cut line may be set in order to form the recessed part of the present invention, and if necessary, the recessed part may be formed by pushing a corner portion where the cut line is set at any time into the inside of the box.

Detailed Description of the Preferred Embodiments

1 is a perspective view of the assembled state of the packaging box according to an embodiment of the present invention from above, 2 is a perspective view of the same view from below, FIG. 3 is a front view, FIG. 4 is a bottom view, and FIG. 5 degrees is a developed view. The box 1 is, for example, a corrugated cardboard product and forms a tetrahedron. And the four corner parts of the lower surface are bend | folded inward, and the recessed part 2 is formed.

The concave portion 2 is formed by inclining the corner portion of the box 1 having a rectangular parallelepiped form inclined planes, and cutting out a right angle triangular weight, and again forming a recessed shape in a triangular shape having the inclined plane as the bottom surface. .

As shown in the development of FIG. 5, the shape of the packaging box is substantially the same as the outline of the outline of the packaging box. That is, the bottom surface portion 3 serving as the bottom surface of the box, the top surface portion 4 serving as the top surface, and the front portion 10 serving as the front surface, the back portion 11 serving as the rear surface, and the side portions serving as the side surface 5, 6 (7), (8, 9, 12, 13, 14, 15) necessary for fixing the adhesive as an adhesive. And the cutting line 16 for folding these parts at substantially right angle is set.

These cutting lines are the same as the conventional ones, and by folding them into the cutting lines 16, a box having a rectangular parallelepiped shape is assembled, and bonded and fixed at the portions 7 to 9 and 12 to 15, The packaging is complete. Therefore, these cutting lines 16 are lines which become a ridge of a box.

Thus, in the present embodiment, cut lines 17 are set in the four corners of the bottom surface 3 again. This cutting line 17 is a part 17a set on the front part 10 or the back part 11, a part 17b set on the bottom part 3, and a part 17c set on the side parts 5, 6 and an adhesive part. It is formed of the portion 17d set in (12-15). When the length of one side of the top and bottom surfaces of the packaging box is 250 to 300 mm, the lengths of the surfaces OA and OB of the triangular portions formed by the cutting lines 17a to 17d and the cutting line 16 are For example, 60-70 mm, the length of the side OC is 30-40 mm, the length of the side OD is 60-70 mm, for example, and the length of the side OE is 30-40 mm. This cutting line 17 is set so that these cutting lines 16 may be mutually connected in the position where three cutting lines 16 which become a ridge of a box gather.

In addition, these cutting lines 16 and 17 can be formed by the method of a press etc. like before. In addition, the cutting line may be used as the cutting line, or the cutting line may be set by the Thompson method of setting the sheath groove over the depth of half in the thickness direction.

In the packaging box configured in this manner, first, the contour shape developed as shown in FIG. 5 is bent at approximately right angles to the cutting line 16 to be formed into a rectangular parallelepiped shape, and bend processing by the bending line 16 is performed. In the process of bending, bending is performed while pushing a portion of the point 0 into the inside of the box so that the point 0 is inside the rectangular parallelepiped according to the cutting line 17.

As a result, as shown in FIGS. 1 to 4, the packaging box 1 having the recesses 2 is assembled. The cutting line of this recessed part 2 is set so that three ridgelines may connect.

Thus, the upper part 4 is opened, and the welding wire (not shown) wound around the coil core is put in the box. The coil-shaped welding wire is stored with its shaft centered perpendicular to the top and bottom surfaces of the welding packaging box. In this case, the recessed portion 2 of the bottom four corners of the box protrudes inside the box, but the welded wire is wound in a coil shape, so that the recessed portion 2 is not disturbed.

Next, the adhesive parts 7 to 9 and 12 to 15 are overlapped with each other to be fixed to each other, so that the assembling of the packaging box containing the welding wire is completed. In the case of assembling the packing box, the adhesive fixing of the upper part 4 is removed, the other part is bonded and assembled together, the welding wire is inserted, the upper part 4 is adhesively fixed and the welding is performed. The wire may be sealed.

At the same time, the present invention can be bent in the same way as before in any of the conventional packaging processes, manual packaging, semi-automatic and fully automatic, and then fixed by hot melt or the like, and then aimed at the pre-set section at four corners. The concave portion can be easily formed by gently pushing this portion with a finger or by automatically pushing the protrusion member.

In this way, the packing box 1 including the welding wire has a recess 2 at its four corners, so that a gap is formed between the bottom of the recess 2 in the state of being placed on the factory or warehouse floor. . Thus, the worker puts his hand into the recess 2 and lifts the box 1 with the fingertip inserted into the recess 2.

Thus, since the recessed part 2 is set in the corner part of the box 1, the operation | work etc. which do not incline the box 1 and insert a hand between the gaps are unnecessary, and a hand is inserted into the recessed part 2 as it is. It is easy to lift the box 2 because it is good.

Moreover, since the box 1 can be transported by putting a finger on the recess 2, the hand does not slip from the box and drop the box 1.

Therefore, according to this embodiment, the completeness at the time of conveyance can be improved remarkably and conveyance workability can be improved.

Moreover, since this recessed part 2 was not formed by cut | disconnecting a corner part, but set it by recessing a corner part inside a box, the intensity | strength of this recessed part 2 is high.

In addition, this invention is not limited to the said Example, Of course, various deformation | transformation is possible. For example, as shown in FIG. 6, the recessed part 2 may be set in the 8 corner | corners of the upper surface and the bottom surface of the box which have a rectangular parallelepiped shape. The expanded view of this packaging box is shown in FIG. In this way, the recessed part 2 can be made into arbitrary corner parts in eight corner parts.

However, as shown in FIG. 7, the side views 10 and 11 are partially cut | disconnected in triangle shape according to the edge side of the recessed part 2. As shown in FIG. This partially cut edge 18 is parallel to the edge side of the recess 2 but is located slightly laterally on the side of the line than the line matching the edge side.

That is, in the developed view, the edge 18 cut off by a triangle larger than the triangular portion cut by the line matching the edge side of the recess 2 is formed. And the cutting line 16 for folding these parts in substantially right angle is set.

In addition, although the cutting line was a straight line in the Example of FIG. 5 and FIG. 7, the cutting line 20 may be made into a curve, for example as shown in FIG. In addition, as shown in the developed view of FIG. 9, three sets of cut lines 21a, 21b, 21c may be set, and these cut lines may be selected in accordance with the size of the stored object to form concave portions of an appropriate size.

In this step, the size of the concave portion can be selected at the stage where the object is determined, and a packaging box having high general versatility for the object can be obtained.

In addition, the present invention may not only set the recessed portion in advance in the container as described above, but also has the advantage that the recessed portion can be set as necessary after the container is formed.

In addition, the packaging box of the present invention can be used for the packaging of all kinds of articles, not only the packaging of the welding wire. In other words, if the recess 2 can be set in at least two of the four corners of the box, it is applicable. It doesn't have to be in the corner of this box.

In the case of an article having a rectangular parallelepiped shape, a foamed styrol for shock absorption is disposed around the article, and the packaging box of the present invention can be provided at least in a corner between the inner surface of the box and the article. Can be applied.

Such articles include audio such as amplifiers, video and speakers, electrical appliances such as video equipment and personal computers.

In addition, cans such as beer cans are arranged in a checkerboard grid shape in a conventional rectangular parallelepiped box, but the four corners are arranged by arranging the cans 30 in a densely packed manner as shown in a planar view in FIG. There is space in the For this reason, by changing the arrangement in this way, the packaging box of the present invention can be applied to packaging such as can beer.
