Description

The present invention relates to a packaging box.

In packaging boxes, the contents may be removed from the box when needed without being moved. In this case, it is preferable for the packaging box to have a lid, as this will prevent dust and other foreign matter from getting inside the box.

Generally, when a packaging box is opened and the opened portion is to be used as a lid, it is necessary to break a portion of the packaging box.
Conventionally, as a means for causing the film to break, it has been known to provide a cutting tape for inducing the break, or to provide a breakable perforation.
Patent Document 1 discloses a packaging box in which a cutting tape for breaking is provided on the inner surface of both side wall panels, and the side wall panels are cut with the cutting tape from a breaking initiation portion formed in an H-shaped cut in the side wall panels, thereby opening the box into a tray-like shape.

The packaging box of Patent Document 1 has a problem in that it is necessary to press into an H-shaped slit formed in a flat side wall panel and pick up the end of the cutting tape, which is time-consuming.
Patent Document 2 discloses a packaging box in which cutting tape is provided on the side wall panels and inner flaps, and a gripping portion is provided at the tip of each inner flap with a pair of tear initiation slits formed along the top and bottom of the tearing portion, and a plurality of slits toward the gripping portion are provided at both side ends of the abutment portion of at least one of the top and bottom outer flaps, and the slits form a push-in portion that can be freely pushed in to enable fingers to be hooked on the edge of the gripping portion.

JP 2002-166927 A Patent No. 4691351

In the packaging boxes of Patent Document 1 and Patent Document 2, when the end of the cutting tape is pinched, an additional operation of pushing the cut portion in is required. Therefore, there is a need for an improvement in the efficiency of the work of breaking the packaging box.

In the following description, the direction in which the pair of first side walls 11, 12 face each other is referred to as the X direction, the direction in which the pair of second side walls 13, 14 face each other is referred to as the Y direction, and the direction perpendicular to the X and Y directions is referred to as the Z direction. The X direction corresponds to the first direction. The Y direction corresponds to the second direction. The Z direction corresponds to the up-down direction. The Z direction will be referred to as the upper side and the lower side as appropriate. The Y direction will be referred to as the right side and the left side as appropriate. The X direction will be referred to as the front side and the rear side as appropriate.
Note that the terms "up and down,""upperside,""lowerside,""rightside,""leftside,""frontside," and "rear side" are names used simply to describe the relative positions of the various parts in the posture shown in FIG. 1, and the actual relative positions may be other than those indicated by these names.

The packaging box 1 is formed by mountain-folding or valley-folding a blank sheet S cut out from a single sheet of cardboard at each of the ruled lines, as shown in Fig. 2. The blank sheet S shown in Fig. 2 is arranged so that the inner side is visible.
Each of the creases (fold lines) that separate the first side walls 11, 12, the second side walls 13, 14, the bottom wall 20 (see Figure 1), and the top wall 30 (see Figure 1) of the blank sheet S is a linear groove formed by pressing the inner surface of the blank sheet S.
It is to be noted that notches (half-cut lines, etc.) may be formed in the creases, which makes it easier to fold the blank sheet S at the creases.

The first side wall 11 is formed in a rectangular shape in a plan view.
A second side wall 13 is connected to the left edge of the first side wall 11 via a line L1 (see FIG. 2).
The second side wall 13 extends rearward from the left edge of the first side wall 11. The second side wall 13 is formed at a right angle to the first side wall 11. The second side wall 13 is formed in a rectangular shape in a plan view.

A joint piece 15 is provided adjacent to the rear edge of the second side wall 13 via a line L2 (see FIG. 2 ). The joint piece 15 is formed in a strip shape along the rear edge of the second side wall 13.
The joining piece 15 is a portion that is joined to the left end portion of the inner surface of the first side wall 12 with an adhesive.

A second side wall 14 is connected to the right edge of the first side wall 11 via a line L3 (see FIG. 2).
The second side wall 14 extends rearward from the right edge of the first side wall 11. The second side wall 14 is formed at a right angle to the first side wall 11. The second side wall 14 has the same shape as the second side wall 13.

The second side wall 14 is connected to the rear edge thereof with a line L4 (see FIG. 2) interposed therebetween.
The first side wall 12 extends leftward from the rear edge of the second side wall 14. The first side wall 12 is formed at a right angle to the second side wall 14. The first side wall 12 has the same shape as the first side wall 11.

The blank sheet S (see FIG. 2) as described above is folded along the lines L1 to L4, and the joining piece 15 is joined to the left inner surface of the first side wall 12, whereby the first side wall 11, the second side wall 13, the first side wall 12, and the second side wall 14 form the rectangular cylindrical body 10.

The lower opening of the body 10 is closed by a bottom wall 20 .
As shown in Fig. 2, the bottom wall 20 is composed of front and rear inner flaps 21 and left and right outer flaps 22. The front and rear inner flaps 21 are connected to the lower edges of the first side walls 11, 12 via creases L5, L6. The inner flaps 21 may be stepped if necessary. The left and right outer flaps 22 are connected to the lower edges of the second side walls 13, 14 via creases L7, L8.
1, the bottom wall 20 is formed by overlapping left and right outer flaps 22 under the front and rear inner flaps 21. The bottom wall 20 is fixed to the butted portions of the left and right outer flaps 22 by, for example, applying an adhesive tape (not shown).

As shown in Fig. 1, the upper opening of the body 10 is closed by a top wall 30. The top wall 30 is composed of a pair of front and rear inner flaps 31 and a pair of left and right outer flaps 32. The front and rear inner flaps 31 are connected to the upper edges of the front and rear first side walls 11, 12 via lines L9, L10. The inner flaps 31 may be subjected to a step-flattening process as necessary. The left and right outer flaps 32 are connected to the upper edges of the left and right second side walls 13, 14 via lines L11, L12.
1, the top wall 30 is formed by overlapping left and right outer flaps 32 on the upper side of the front and rear inner flaps 31. The top wall 30 is fixed by applying an adhesive tape (not shown) to the butted portions of the left and right outer flaps 32. The packaging box 1 is a so-called A-type packaging box.

The hand hole 17 is provided in each of the first side walls 11 and 12 (only the hand hole 17 in the first side wall 11 is shown in FIG. 1). The hand hole 17 is provided in the first side walls 11 and 12 at positions facing each other in the X direction. The hand hole 17 is bent when pressed in the X direction to form an opening for holding the package box 1 when it is transported.

FIG. 3 is an enlarged view of the hand hole 17 as viewed from the outside.
3, hand hole 17 is generally rectangular in front view. Hand hole 17 is formed in the center of first side walls 11, 12 in the Y direction. Hand hole 17 is formed below the center of first side walls 11, 12 in the Z direction. Hand hole 17 is positioned so as not to interfere with the contents of packaging box 1 when a hand is inserted.

The hand hole 17 is surrounded by a fold line 51, a first cut line 52, a third cut line 53, and a fourth cut line 54. The fold line 51 is located on the upper side of the hand hole 17 and extends in the Y direction. The first cut line 52 is formed on both sides of the hand hole 17 in the Y direction. The first cut line 52 extends in the vertical direction. The third cut line 53 extends in the Y direction and connects the lower ends of the first cut lines 52. The fourth cut line 54 is formed in an arc shape that is tangent to the fold line 51 and the first cut line 52. In addition, the hand hole 17 has a cut line 55 formed in the center in the Y direction that extends in the vertical direction. By forming the cut line 55, when the hand hole 17 is pushed in, the +Y side part and the -Y side part can be locally and individually pushed, reducing the load when pushing.

The cutting means T is provided at a portion of the packaging box 1 to be cut. The cutting means T is, for example, a liner cutter, a zipper, a cutting tape, etc. In the present invention, a cutting tape that does not affect the strength of the packaging box 1 is most preferable. In the following, the cutting means will be described as the cutting tape T.
The cutting tape T is made of, for example, resin. In the blank sheet S, the cutting tape T is arranged on the inner surface of the body 10 across the first side wall 12, the second side wall 14, the first side wall 11, the second side wall 13, and the joint piece 15, in the center of the hand hole 17 in the vertical direction. In the assembled packaging box 1, the cutting tape T extends from the first side wall 11 through the second side wall 14 to the first side wall 12, and also extends from the first side wall 11 through the second side wall 13 to the first side wall 12. The cutting tape T is parallel to the lines L5 to L8 that form the lower edges of each wall, and is also parallel to the lines L9 to L12 that form the upper edges of each wall. The packaging box 1 can be opened and separated into upper and lower parts by cutting off the area including the cutting tape T in a strip shape.

The gripping portion 41 is provided on both sides of the hand hole 17 in the Y direction. The gripping portion 41 has a cut tape T attached to its inner surface. The gripping portion 41 is formed in an area surrounded by the first cut line 52 and a pair of second cut lines 56A, 56B. The pair of second cut lines 56A, 56B are formed with a gap in the vertical direction. The pair of second cut lines 56A, 56B are located outside the hand hole 17 in the Y direction and extend in the Y direction. The second cut line 56A located on the upper side of the pair of second cut lines 56A, 56B includes a fifth cut line 57. The fifth cut line 57 extends from the inner end of the second cut line 56A in the Y direction toward the fourth cut line 54 in the normal direction of the fourth cut line 54. Of the pair of second cut lines 56A, 56B, the second cut line 56B located on the lower side is located on an extension of the third cut line 53.

In the packaging box 1 configured as above, the hand hole 17 is first pushed inward in the X direction to break the third cut line 53 in the first side walls 11, 12. As a result, as shown in FIG. 4, the hand hole 17 is folded at the fold line 51 and pushed inward in the X direction. By pushing the hand hole 17 inward, an opening 17A for holding the hands is formed in the first side walls 11, 12.

At this time, the end of the gripping portion 41 is exposed in the opening 17A. Then, for example, the gripping portion 41 located on the +Y side is gripped from the opening 17A and pulled outward in the Y direction as shown in FIG. 5, and the gripping portion 41 is cut off from the first side wall 11 along the second cut lines 56A, 56B. Then, the gripping portion 41 is moved from the first side wall 11 through the second side wall 14 to the gripping portion 41 on the first side wall 12. This causes the cut piece TA on the +Y side, which is the portion including the cutting tape T, to be cut off along the cutting tape T.

Next, the gripping portion 41 located on the -Y side is gripped in the same way as the gripping portion 41 located on the +Y side, and while being pulled outward in the Y direction, it is moved from the first side wall 11 through the second side wall 13 to the gripping portion 41 on the first side wall 12. This causes the cut piece TA on the -Y side, which is the portion that includes the cutting tape T, to be cut off along the cutting tape T. By cutting off the cut pieces TA on both sides in the Y direction, the packaging box 1 can be opened into a tray shape.

As described above, in the packaging box 1 of this embodiment, the gripping portion 41 for pulling the cutting tape T is formed in the area surrounded by the pair of first cut lines 52 that form the hand hole 17 and the second cut lines 56A, 56B located outside the pair of first cut lines 52 in the Y direction, so that the end of the gripping portion 41 is exposed in the opening 17A for handling. Therefore, in the packaging box 1 of this embodiment, there is no need to perform a separate task of pushing in the slit in order to grip the gripping portion 41.
In addition, in the packaging box 1 of this embodiment, the fold line 51, the third cut line 53, and the cut line 55 of the hand hole portion 17 form an H-shaped cut that serves as a guide when cutting the cut tape T, so that the hand hole portion 17 also serves as the H-shaped cut, which can suppress deterioration in strength compared to the case where the hand hole portion 17 and the H-shaped cut are provided separately.
Therefore, in the packaging box 1 of this embodiment, deterioration in strength can be suppressed, and the breaking operation for opening the box into tray-like packages can be efficiently carried out.

In addition, in the packaging box 1 of this embodiment, the fourth cut line 54 that forms the upper corner of the opening 17A is arc-shaped, so that it fits the hand when handling it, can be gripped firmly, and can be made to feel soft to the touch. In addition, in the packaging box 1 of this embodiment, the second cut line 56A includes the fifth cut line 57 that extends toward the fourth cut line 54 in the normal direction of the fourth cut line 54, so that the gripping portion 41 can be smoothly separated from the first side wall 11 when the gripping portion 41 is gripped and pulled.

[Second embodiment]
Next, a second embodiment of the packaging box 1 will be described with reference to FIGS.
In these figures, the same elements as those in the first embodiment shown in FIGS. 1 to 5 are designated by the same reference numerals, and the description thereof will be omitted.

The blank sheet S as described above is folded along the lines L21 to L24, and the joining piece 15 is joined to the right inner surface of the top wall 30, so that the bottom wall 20, the second side wall 14, the top wall 30, and the second side wall 13 form a rectangular cylindrical body 10.

The front opening of the body 10 is closed by a first side wall 11 .
As shown in FIG. 7, the first side wall 11 is composed of left and right side flaps 11A which serve as inner flaps, and an upper flap 30A and a lower flap 20A which serve as outer flaps.
The left and right side flaps 11A are connected to the front edges of the second side walls 13, 14 via lines L25, L26.
The upper flap 30A protrudes in the X direction from the top wall 30. The upper flap 30A is connected to the front edge of the top wall 30 via a line L29.
The lower flap 20A protrudes in the X direction from the bottom wall 20. The lower flap 20A is connected to the front edge of the bottom wall 20 via a line L30. The upper flap 30A and the lower flap 20A may be subjected to a step-flattening process as necessary.

As shown in FIG. 6, the first side wall 11 is formed by butting together the left and right side flaps 11A as inner flaps in the Y direction, and folding and stacking the upper flap 30A and the lower flap 20A as outer flaps protruding in the X direction outward from the side flaps 11A in the X direction.
The first side wall 11 is fixed to the butted portions of the left and right side flaps 11A by, for example, applying an adhesive tape (not shown).

The hand hole 17 of the first side wall 11 in this embodiment is formed across a pair of side flaps 11A that are butted together in the Y direction. The hand hole 17 of the first side wall 12 in this embodiment is formed across a pair of side flaps 12A that are butted together in the Y direction. The hand hole 17 and gripping portion 41 of the first side walls 11, 12 are provided in an exposed state between the upper flap 30A and the lower flap 20A.

FIG. 8 is an enlarged view of the hand hole 17 according to this embodiment as viewed from the outside.
As shown in Fig. 8, the gripping portion 41 including the first cut line 52, the fourth cut line 54, the second cut lines 56A, 56B, and the fifth cut line 57 in the hand hole portion 17 of the first side wall 11 is arranged separately on one side flap 11A and the other side flap 11A sandwiching the butt line 11B extending in the Z direction. The fold line 51 and the third cut line 53 in the hand hole portion 17 are perpendicular to the butt line 11B at the center in the Y direction. The cut tape T extends in the Y direction and is perpendicular to the butt line 11B at the center position in the up-down direction of the hand hole portion 17.
The hand hole 17, the gripping portion 41 and the cutting tape T of the first side wall 12 have the same configuration as those of the first side wall 11 described above.

In the packaging box 1 having the above configuration, as in the first embodiment, the hand hole portion 17 is first pushed inward in the X direction to break the third cut line 53 relative to the first side walls 11 and 12, and then pushed further inward to form an opening 17A for handling in the first side walls 11 and 12.
9, the gripping portion 41 is gripped and pulled outward in the Y direction from the opening 17A, and the gripping portion 41 is cut off from the first side wall 11 along the second cut lines 56A, 56B.
