Description

The present invention relates to a packaging box that can be used both as a packaging for transporting goods and as a display at a store.

Conventional packaging boxes of this type include those according to Japanese Patent No. 3883517.
This wrapping box is "sealed by stacking the inner flap and the outer flap extending from each pair of end walls and the upper edge of the side wall, respectively, with a cross line of the side wall and two vertical lines extending from the side wall to the outer flap. In a packing display box for displaying products by cutting the crossing line of the outer flap, a part of the cut tape attached over the entire circumference of the peripheral wall consisting of each pair of end walls and side walls is used as the crossing line. The tangent line of the side wall is made to wrap around to both end walls, the tangent line of the outer flap is extended to both side edges, and the tangent line from the inner flap to the end wall that overlaps below it reaches the tangent line that wraps around from the side wall, and the side wall The cut tape was cut to form a cut end portion to be the start end of the horizontal cut line, and the cut tape was cut to form the cut end portion to be the end of the horizontal cut line and the vertical cut line on the end wall. ”

Further, a lower edge cutting line 121 formed of perforations is formed at the boundary between the front surface 100 and the lower outer flap 410A, that is, the lower edge 120 of the front surface 100.

Further, the front surface 100 is formed with ruled lines 140L and 140R on the upper front side and 150L and 150R on the lower side of the front surface. The ruled line is a line in which the bent portion is crushed so that the corrugated cardboard can be bent neatly when assembled into a three-dimensional shape such as a box.

The front upper bending lines 140L and 140R are formed at an angle of 45 ° between the upper edge 110 of the front surface 100 and the vertical cutting lines 130L and 130R. That is, assuming that the width dimension of the front surface 100 is A, the portion where only A / 6 is inserted inward from the end of the upper edge 110 is the first point P1L, P1R, and the vertical cutting line 130L from the end of the upper edge 110. The portions lowered by A / 6 along 130R are designated as the second points P2L and P2R, and the front upper bending lines 140L and 140R are formed so as to connect the first points P1L and P1R and the second points P2L and P2R. ..

Further, the front lower side bending lines 150L and 150R are formed obliquely between the vertical cutting lines 130L and 130R and the lower edge 120 of the front surface 100. That is, when the intersection of the virtual lines PVL and PVR (indicated by the alternate long and short dash line) and the lower edge 120 hanging from the first points P1L and P1R toward the lower edge 120 of the front surface 100 is defined as the third points P3L and P3R. The front lower side bending lines 150L and 150R are formed so as to connect between the second points P2L and P2R and the fourth points P4L and P4R located slightly above the third points P3L and P3R.

That is, the front upper bending lines 140L and 140R and the front lower lower bending lines 150L and 150R are connected at the second points P2L and P2R.
The first points P1L and P1R, the third points P3L and P3R, and the fourth points P4L and P4R are formed on the virtual lines PVL and PVR shown by the alternate long and short dash lines, respectively, but the vertical cutting lines 130L and 130R and the virtual lines are formed. The PVL and PVR are separated by A / 6.

From the upper edge 110 of the front surface 100, an upper outer flap 400A having the same width dimension as the front surface 100 and having a length dimension of about 1/2 of the width dimension of the side surfaces 300A and 300B extends.
The upper outer flap 400A is formed with an opening cutting line 401A as a zipper line parallel to the side facing the upper edge 110. When the assembled packaging box 1000 is opened, the opening cutting line 401A has the upper outer flap 400A with the sealing tape 700 that is sealed across the upper outer flap 400A and the other upper outer flap 400B. It is a part that is cut when peeled off together with a part of.

Further, in the middle portion of the opening cutting line 401A, a handle hole for inserting a finger or the like in order to make a start for cutting the vertical cutting lines 130L and 130R when removing the upper outer flap 400A and the like. A notch 402 is formed to form the 402A (see FIG. 4).
Further, the upper outer flap 400A is formed with a pair of outer flap bending lines 403L and 403R which are diagonal ruled lines extending from the notch 402 toward both ends of the upper edge 110.

Further, from the lower edge 120 of the front surface 100, a lower outer flap 410A having the same width dimension as the front surface 100 and having a length dimension of about 1/2 of the width dimension of the side surfaces 300A and 300B extends. ..
On the lower edge 120, a lower edge cutting line 121 formed of perforations is formed between the vertical cutting lines 130L and 130R, that is, over the entire length of the boundary between the front surface 100 and the lower outer flap 410A.

On the other hand, from the upper edge 210 of the back surface 200, an upper outer flap 400B having the same width dimension as the back surface 200 and having a length dimension of about 1/2 of the width dimension of the side surface 300A and 300B extends. The upper outer flap 400B is set to the same size as the upper outer flap 400A.
Further, from the lower edge 220 of the back surface 200, a lower outer flap 410B having the same width dimension as the back surface 200 and having a length dimension of about 1/2 of the width dimension of the side surfaces 300A and 300B extends. The lower outer flap 410B is set to the same size as the lower outer flap 410A.

A substantially trapezoidal joint margin 250 is formed so as to protrude from one edge of the back surface 200 (the edge opposite to the side surface 300A). The joint margin 250 is a portion connected to the inner surface of the other side surface 300B.
The back surface 200 is not formed with the vertical cutting lines 130L and 130R on the front surface 100, the front upper bending lines 140L and 140R, and the front lower bending lines 150L and 150R.

Further, from the upper edge 310A of the side surface 300A, an upper inner flap 500A having the same width dimension as the side surface 300A extends. The upper inner flap 500A is formed in a substantially L-shaped modified hexagonal shape in which the upper corner portion on the upper inner flap 400A side is cut out in a rectangular shape. Further, the upper inner flap 500A has an inner flap first cutting line 501A which is a zipper line along the upper edge 310A and an inner flap second cutting line which is a perforation perpendicular to the end of the inner flap cutting line 501A. A line 502A is formed.
The inner flap first cutting line 501A and the inner flap second cutting line 502A are for cutting out a portion exposed when the upper outer flap 400 is removed.
The upper inner flap 500B connected to the upper edge 310B of the other side surface 300B is formed symmetrically with the above-mentioned upper inner flap 500A.

As shown in FIG. 3, in the packaging box 1000 composed of the above-mentioned surfaces, the upper outer flap 400A and the upper outer flap 400B are closed from above the upper inner flap 500A and the upper inner flap 500B. The upper surface is sealed by the sealing tape 700 being attached so as to straddle the upper outer flap 400A and the upper outer flap 400B. Of course, on the bottom surface, the lower outer flap 410A and the lower outer flap 410B are closed from above the lower inner flap 510A and the lower inner flap 510B, and the sealing tape 710 is used for the lower outer flap 410A and the lower outer flap 410A. It is sealed by being pasted across 410B.

In the packaging box 1000 sealed in this way, the upper outer flap 400A and a part of the front surface 100 connected to the upper outer flap 400A can be removed by the following procedure.
First, as shown in FIG. 4, the notch 402 is opened to form the handle hole 402A in the state of being sealed with the sealing tape 700. A hand or the like is inserted into the handle hole 402A, and the upper outer flap 400A is pulled upward.
Then, in the packaging box 1000, the outer flap bending lines 403L and 403R are lifted as the upper outer flap 400A is pulled upward, the opening cutting line 401A is cut, and the upper outer flap 400A is opened. ..
The outer flap bending lines 403L and 403R are slightly mountain-folded to promote smooth cutting of the opening cutting line 401A.

By pulling the upper outer flap 400A opened by cutting all the opening cutting lines 401A further downward and toward the front side together with the front surface 100, the vertical cutting lines 130L and 130R are sequentially cut from the upper side to the lower side. Will be done.
Until the vertical cutting lines 130L and 130R reach the second points P2L and P2R, the front upper bending lines 140L and 140R are mountain-folded to promote the cutting of the vertical cutting lines 130L and 130R. It becomes smooth and the cutting does not deviate from the vertical cutting lines 130L and 130R.

Further, when the vertical cutting lines 130L and 130R are cut and reach the second points P2L and P2R, the front lower side bending lines 150L and 150R formed on the front surface 100 are valley-folded. By making the lower front bending lines 150L and 150R valley folds, the cutting of the vertical cutting lines 130L and 130R is promoted and smoothed, and the effect of preventing the cutting from deviating from the vertical cutting lines 130L and 130R. Occurs.

With the vertical cutting lines 130L and 130R cut to the lower end, the lower edge cutting line 121 of the lower edge 120 of the front surface 100 is cut. As a result, the upper outer flap 400A and the front surface 100 connected to the upper outer flap 400A are separated from the packaging box 1000. That is, all the portion corresponding to the front surface 100 is opened, and the portion corresponding to a part of the upper outer flap 400A is opened.

From a state where the upper outer flaps 400A as shown in FIG. 6 is disconnected, further upper inner flaps 500A, the flap among a zipper line formed on 500B first cutting line 501A, and 501B, the inner flap second cutting line By cutting the 502A and 502B , as shown in FIG. 7, the exposed portions of the upper inner flaps 500A and 500B can be removed.
As a result, the portion corresponding to the front surface 100 and the upper outer flap 400A is completely released.

In the packaging box 1000 according to the above-described embodiment, the front upper bending lines 140L and 140R of the front surface 100 and the front lower side bending lines 150L and 150R are connected at the second points P2L and P2R, but the front upper side is connected. The folding lines 140L and 140R and the front lower side bending lines 150L and 150R are not limited to such a configuration, and may be as shown in FIG.
That is, in this packaging box 1000S, the front upper bending lines 140L and 140R are formed on the line connecting the first points P1L and P1R and the second points P2L and P2R, but do not reach the second points P2L and P2R. It has become like. Further, in this packaging box 1000S, the front lower side bending lines 150L and 150R are formed on the lines connecting the second points P2L and P2R and the fourth points 4L and P4R, but reach the second points P2L and P2R. It is designed not to be done.
The first point P1L, P1R, the third point P3L, P3R, the fourth point P4L, and P4R are formed on the virtual lines PVL and PVR shown by the alternate long and short dash line, respectively, but the width dimension of the front surface 100 is set to A. In this case, the vertical cutting lines 130L and 130R are separated from the virtual lines PVL and PVR by A / 6, which is the same as the packaging box 1000 described above.
Since the other parts of the packaging box 1000S are the same as those of the packaging box 1000 described above, detailed description thereof will be omitted.

The reason why the front upper bending lines 140L and 140R and the front lower lower bending lines 150L and 150R are not continuous like this packaging box 1000S is in consideration of the case where the packaging boxes 1000S are stacked for storage or the like.
Generally, in this type of corrugated cardboard packaging box, the strength in the vertical direction is secured at the corner portion of the packaging box more than other portions, so that the vertical cutting lines 130L and 130R are formed up to the corner portion. This is because if the front upper bending lines 140L and 140R and the front lower lower bending lines 150L and 150R are made continuous, there is a problem that the strength is lowered at the corners, and there is a risk of accidents such as body swelling and collapse. ..

Further, in the above-described embodiment, the front upper folding lines 140L and 140R and the front lower folding lines 150L and 150R are A from the end of the upper edge 110 toward the inside when the width dimension of the front surface 100 is A. The portion containing only / 6 is defined as the first points P1L and P1R, and the virtual lines PVL and PVR hanging from the first points P1L and P1R toward the lower edge 120 are used as a reference. It is not limited to this.
When the width dimension of the front surface is A, the virtual lines PVL and PVR may be within a range of A / 6 to A / 5 inward from the end of the upper edge.
By forming the front upper bending lines 140L and 140R and the front lower bending lines 150L and 150R according to the virtual lines PVL and PVR, the front 100 is cut by cutting the vertical cutting lines 130L and 130R following the cutting of the upper outer flap 400A. The cutting can be done smoothly and smoothly without coming off.
