Description

The present invention relates to a packaging box for storing a long material.

In the interior of a building, when making a floor and a wall, there will be a gap in the construction, so a skirting board will be installed to hide it. Such skirting boards may be cut to a certain length, stacked and stored in an elongated packaging box, transported to a site, and the packaging box may be opened and taken out for use at the site.

In addition, in the conventional packaging box for long materials, after opening the box from the front or the back and taking out the long material, the opened part was left open, so the long material is inside. When carrying the remaining boxes, long materials often popped out of the open mouth and fell off.

Further, although it is not a box for long materials, a packaging box has been proposed in which the contents can be taken out by opening a part of the packaging box without crushing the packaging box. The packaging box is connected to the bottom plate, front, rear, left and right side walls surrounding the bottom plate with an upper edge for partitioning an opening facing the bottom plate, and the upper edge of the rear wall, which is one of the side walls. It comprises a top plate that covers the opening and a front plate portion that is connected to the front edge of the top plate and joined to the outer surface of the front wall, and the top plate is located on the front edge of the top plate from a pair of left and right front ends. A region surrounded by the first perforation in the top plate, which is provided with a first perforation extending toward the upper edge of the rear wall, is a first opening portion for providing the opening, and the front plate. The portion includes an intermediate portion sandwiched between a pair of left and right second perforations extending from each front end of the first perforation to the lower edge of the front plate portion, and the front wall has an upper edge of the front wall. A cut portion that is provided with a third perforation that borders the shape as one side and is a portion surrounded by the third perforation is joined to the inner surface of the intermediate portion, and the cut portion is connected to the outer surface of the front wall. When viewed from the opposite direction, the cut portion has a portion protruding below the lower edge of the middle portion and has a width equal to or less than the middle portion in the left-right direction, and the cut portion has one side of the lower edge of the cut portion. It is known that the insertion portion, which is a portion surrounded by the fourth perforation, includes the protruding portion when viewed from the direction facing the outer surface of the front wall. (See, for example, Patent Document 1).

When opening the above-mentioned packaging box, first, the central portion of the front plate portion is pinched by a user's finger or the like, and the central portion of the front plate portion is cut so that the perforations of the front plate portion are cut. , It is pulled up with respect to the left and right ends of the front plate portion, and the perforations on the top plate are cut.

However, in the case described in Patent Document 1, the entire top plate cannot be pulled up. Therefore, when the long material is stored so as not to leave a wasted space inside the packaging box, the long material is used. It cannot be taken out smoothly. Further, if the packaging box is crushed and taken out, if the long material remains, it cannot be stored well.

Further, as described above, in the conventional packaging box for long materials, after the box is opened from the front or the rear and the long material is taken out, the opened part is left untouched, so that the long material is long. There was a problem that the long material popped out from the open mouth when carrying the box with the material left inside.

INDUSTRIAL APPLICABILITY The present invention provides a packaging box in which a long material stored inside can be smoothly taken out, the rest can be stored, and the long material is prevented from falling even during transportation. The purpose is to do.

The packaging box according to one aspect of the present invention is a packaging box formed in a hexahedron shape having front and rear surfaces, left and right side surfaces, and upper and lower surfaces, and is formed of corrugated cardboard for storing a long material, and has a lower surface.

<1. Structure of the packaging box of this embodiment>
As shown in FIG. 1, the packaging box 1 is, for example, a hexahedron made of a piece of corrugated cardboard, and long thin plate-shaped materials (not shown) are stacked and stored along the longitudinal direction. It is a thing. Further, the packaging box 1 includes a front plate portion 2 forming a front-rear surface in the longitudinal direction, a rear surface plate portion 3, a right side plate portion 4 forming left and right side surfaces, a left side plate portion 5, and an inner left side arranged inside the front plate portion 5. The face plate portion 5A, the upper surface plate portion 6 forming the upper and lower surfaces, and the lower surface plate portion 7 are provided as the main configurations.

The upper surface plate portion 6 and the lower surface plate portion 7 of the packaging box 1 have a size corresponding to a thin plate-shaped long material, but when the number of stacked sheets is large, the length of the long material is long so that it can be easily taken out. It can be a little longer than that. The left side plate portion 5 connected to the upper surface plate portion 6 in the assembled state is located outside the inner left side surface plate portion 5A connected to the lower surface plate portion 7, and the left side surface has a double plate structure. It has become.

The long material stored in the packaging box 1 is, for example, a skirting board. Since the packaging box 1 of the present embodiment is made of corrugated cardboard, the strength required for a packaging box of a skirting board which is a long material is secured.

As shown in FIG. 2, in the front side portion of the packaging box 1, a rectangular front side inner surface plate portion 11 extending vertically upward from the front edge of the lower surface plate portion 7 is arranged on the front plate portion 2, and the right side plate portion 4 and the right side plate portion 4. The left and right front side plate portions 13 and 14 extend from the front edge of the left side plate portion 5 to the center side, respectively, and the left and right side plate portions 13 and 14 are adhered to the front side of the front inner surface plate portion 11.

In the left and right front side plate portions 13, 14, a part of the lower end on the central portion side is cut into a 1/4 circular shape, and cutouts 13a and 14a are formed. It should be noted that the notches 13a and 14a are not essential configurations, and a configuration without these notches 13a and 14a may be used.

Further, a front plate portion 2 extending downward from the front edge of the top plate portion 6 via a hinge portion is adhered to the outside of the front side surface plate portions 13 and 14, and the front plate portion 2 is the front surface of the packaging box 1.

Separation lines L1 and L2 are formed. Therefore, when the front plate portion 2 is pulled upward, the adhesive portion of the front plate portion 2 is peeled off, and when the front plate portion 2 is further pulled up, the separation lines L1 and L2 are separated, and the left and right side edges of the top plate portion 6 and the right side plate portion 4 are separated. And the upper edge of the left side plate portion 5 are separated, and the front side portion of the upper surface plate portion 6 can be opened upward.

In this embodiment, the separation lines L1 and L2 are formed with a length of about 10 cm to 15 cm. This is because it is easy to take out the long material with the front plate portion 2 open, and it is difficult for the long material to pop out with the front plate portion 2 closed.

Therefore, since the upper part of the front side of the box can be opened, the long material housed inside the packaging box 1 can be easily taken out from the upper side. In this case, since the notches 13a and 14a form a space (gap) between the front plate portion 2 and the front side plate portions 13 and 14, it is easy to catch a finger, and the front plate can be easily caught by using the space. The portion 2 can be easily pulled upward.

In this way, by pulling up the front plate portion 2 upward to separate the separation lines L1 and L2, the front side portion of the top plate portion 6 can be opened. Can be taken out.

Further, even after the front plate portion 2 is pulled up to separate the separation lines L1 and L2, the packaging box 1 maintains the overall shape as it is. Therefore, after taking out the long material, the front plate portion 2 can be inserted inside (rear side) of the front inner surface plate portion 11. Therefore, when the long material remains in the field, the front plate portion 2 can be inserted inside the front inner surface plate portion 11 to firmly close the mouth, so that the remaining long material is carelessly left. Can be stored as it is so that it does not pop out.

Further, since the upper surface plate portion 6 and the lower surface plate portion 7 of the packaging box 1 have a size corresponding to the thin plate-shaped long material, the long material can be stored without having wasted space.

On the other hand, as shown in FIGS. 3, 4, and 5, in the rear portion of the packaging box 1, the rear inner surface plate portion 21 extends vertically upward from the trailing edge of the lower surface plate portion 7, and the outside thereof ( On the rear side), rear side surface plate portions 22 and 23 extending from the trailing edges of the right side plate portion 4 and the left side plate portion 5 toward the central portion are arranged. Then, the rear surface plate portion 3 extending downward from the trailing edge of the upper surface plate portion 6 is adhered to the outside of the rear side surface plate portions 22 and 23, and the rear surface plate portion 3 is the rear surface of the packaging box 1. In this embodiment, since the rear inner surface plate portion 21 and the rear side side plate portions 22 and 23 are not adhered to each other, the box can be smoothly opened when opening the box from the rear side, such as when taking out all the long materials. be able to.

Further, a notch 21a cut out in a substantially semicircular shape from the upper edge is provided in the upper center of the rear inner surface plate portion 21. As a result, when opening the box from the rear side, the box can be opened smoothly by putting a finger on the notch 21a and opening it outward. For example, when using all the long materials in the box, it is advisable to open the box from the rear side. The notch 21a is not an essential configuration, and may have a configuration without the notch 21a (see FIG. 6).

<2. Effect of packaging box of this embodiment>
