Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a packaging box whose top surface includes a pair of top plates.

[Conventional technology]

FIG. 4 is a diagram showing a conventional packaging box (Japanese Utility Model Publication No. 54-36934) whose upper surface consists of a pair of upper plates.
In the figure, 21 is the bottom surface, 22 is a pair of side surfaces, 2
3 is a top surface; 24 is a pair of end surfaces; 3 is a pair of top plates constituting the top surface 23; and 7 is an adhesive tape stuck to the abutting portion of the top plate 3 and the end surface 24.

FIG. 5 is a diagram showing the packaging box material of the packaging box shown in FIG. 4. In the figure, 1 is a bottom plate, 2 is a side plate provided on both sides of the bottom plate 1, 3 is a top plate provided on the sides of both side plates 2, and 4 is provided on both ends of the bottom plate 1. End flap, 5 is both side plate 2
Reference numeral 6 indicates end flaps provided at both ends of both top plates 3.

In order to create a packaging box in which an object is packaged using the packaging box material shown in FIG. 5, first, as shown in FIG. After folding, put the item to be packaged inside, then fold one flap 5 at the boundary line between one side plate 2 and the flap 5 as shown in Fig. 6b, and then fold the flap 5 as shown in Fig. 6c. As shown in FIG. 3, then fold the flap 6 along the boundary line between the top plate 3 and the flap 6 as shown in Fig. 6e, and then fold the flap 6 between the bottom plate 1 and the flap 4 as shown in Fig. 6f. The flap 4 is bent along the boundary line, and finally, the adhesive tape 7 is attached to the abutting portion of the top plate 3 and the flap 4, as shown in FIG. 6g.

[Problem that the invention seeks to solve]

By the way, in such a packaging box, when a part of the packaged item inside is to be taken out, the adhesive tape 7 is peeled off, and then the ridge line 14 between the top surface 23 and the end surface 24 is cut open with a cutter or the like. However, in this case, when cutting the ridge line 14 with a cutter or the like, there is a risk of damaging the packaged item inside.Moreover, cutting the ridge line 14 reduces the strength of the package, so cutting the remaining package When the packaged items are transported or stacked for storage, they are easily deformed, making transportation inconvenient and causing the items to collapse.

This invention was made in order to solve the above-mentioned problems.
The purpose of the present invention is to provide a packaging box that does not cause damage to the internal packaged items and does not easily deform when the remaining packaged items are transported or stacked for storage. .

[Means for solving problems]

In order to achieve this object, the present invention has a bottom surface, a pair of side surfaces, a top surface and a pair of end surfaces, and the top surface is composed of a pair of top plates, and an adhesive tape is applied to the abutting portions of the top plates and the end surfaces. In the attached packaging box, a perforation is provided in the vicinity of the ridge line between the top surface and the end surface of the top plate, and is substantially parallel to the ridge line, and is located outside the perforation of the adhesive tape and inside the ridge line. Provide a cutting score line.

[Effect]

In this packaging box, when taking out a part of the packaged item inside, the adhesive tape is peeled off from the area between the cutting lines, and then the top plate is cut along the perforations.

〔Example〕

FIG. 1 is a diagram showing a packaging box according to the present invention. In the figure, 8 is a perforation provided near the ridgeline 14 of the top plate 3;
It is almost parallel to 4. Reference numeral 13 denotes a cutting score line provided in the adhesive tape 12, and the cutting score line 13 is provided outside the perforation 8 and inside the ridge line 14.

FIG. 2 is a view showing the packaging box material of the packaging box shown in FIG. 1, in which perforations 8 are provided substantially parallel to the boundary line between the top plate 3 and the flap 6.

In order to create a packaging box in which an item to be packaged is packaged using the packaging box material shown in Figure 2, first see Figure 3a.
As shown in Fig. 3, it is bent at the boundary line between the bottom plate 1 and the side plate 2, and then, as shown in Fig. 3b, the object to be packaged 11 is placed inside, and then, as shown in Fig. 3c, After bending the top plate 3 at the boundary line between the side plate 2 and the top plate 3 and bending the flap 5 at the boundary line between the side plate 2 and the flap 5, apply adhesive 10 to the flap 5, and then apply the adhesive 10 to the flap 5. As shown in Figure d, the flaps 4 and 6 are bent at the boundary line between the bottom plate 1 and the flap 4 and the boundary line between the top plate 3 and the flap 6, and the flaps 4 and 6 are glued to the flap 5 with adhesive 10. Finally, as shown in FIG.
2, cut score lines 13 are provided on the adhesive tape 12.

In this packaging box, when taking out a part of the packaged item 11 inside, after tearing off the part 12a of the adhesive tape 12 between the cut lines 13,
Since it is sufficient to cut the top plate 3 along the perforations 8, there is no risk of damaging the packaged items inside when cutting the top plate 3. Moreover, the portion of the top plate 3 near the ridgeline 14 remains as it is, and the portion 12b of the adhesive tape 12 other than the portion 12a remains on the ridgeline 14, so the strength will not decrease.
It does not easily deform when the remaining packaged items 11 are transported or stacked for storage.

Note that as the material, cardboard, fiber, etc. can be used.

〔Effect of the invention〕

As explained above, in the packaging box according to the present invention, when a part of the packaged items inside is taken out, there is no risk of damaging the packaged items inside, and the remaining packaged items are kept in a state It is convenient to transport because it does not easily deform when transported or stacked for storage, and the load does not collapse. As described above, the effects of this invention are remarkable.
