DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair dyeing article,
The present invention relates to a display carton in which tools or tools such as cosmetics, personal care products, toys, and miscellaneous goods are stored to facilitate opening and enhance the display effect at stores. More specifically, the present invention relates to a carton with an opening zipper which is gripped by an opening knob piece formed along the cut line and opened by tearing the paperboard along a zipper continuous from the cut line in a direction crossing the cut line.

[0002]

2. Description of the Related Art Conventionally, as a carton with an opening zipper of this kind, for example, as shown in FIG. 5, a zipper 3 'is provided in the longitudinal direction of the carton which intersects with a substantially L-shaped cut line 1'. There is a case in which the paperboard P 'is torn along the zipper 3' from the cut line 1 'by holding the opening knob piece 2' formed along the cut line 1 'and pulling it apart from the carton. . On the other hand, according to the practice of the industry, regardless of the presence or absence of the zipper, the grain direction of the paperboard constituting the zipper is designed to intersect at right angles with the longitudinal direction of the assembled carton as shown by the arrow in FIG. It is common. Further, the carton paperboard is easily broken in a direction parallel to the grain,
There is also a property that it is hard to be broken in the "side eyes" direction perpendicular to this. The term “grain direction” used in the present application is referred to as “JIS Handbook 1997 paper.
The term "longitudinal direction (vertical direction of paper)" as defined in "pulp", that is, the direction of paper in the same direction as the paper travels when making paper with a paper machine. The abbreviation is MD. "

[0003]

However, in such a conventional carton with an opening zipper, the opening direction of the opening knob piece and the paper grain direction of the paperboard are arranged in parallel, and the paper grain direction of the paperboard is aligned. Since the zipper intersects, when the user grips the opening knob piece and pulls it away from the carton, in the initial stage of the opening, a breaking force acts in the paper grain direction, which is the direction in which the cut line extends in the cut line. Since the resistance required to tear from the score line to the zipper crossing the grain direction is much greater than the resistance required to tear in the grain direction, the score line to the zipper It is easy to cut in the direction of the paper without cutting, and as a result, there is a problem that the cut does not enter neatly along the zipper from the cut line and cannot be opened properly.

SUMMARY OF THE INVENTION The object of the present invention is to break cleanly without shifting the position along a zipper from a cutting line. In addition to the object of the first aspect of the present invention, even if the zipper has a structure in which the zipper is torn in a direction intersecting the opening direction, the zipper can be neatly broken without being displaced along the zipper from the cut line. It is intended to do so. The third aspect of the present invention aims at giving the user a sense of security in addition to the object of the first or second aspect of the present invention.

[0005]

In order to achieve the above-mentioned object, the invention according to claim 1 of the present invention is arranged such that the opening direction of the opening knob piece intersects with the grain direction of the paperboard,
The grain direction of the paperboard and the zipper are arranged substantially in parallel. According to a second aspect of the present invention, in the configuration of the first aspect, the zipper has a half-cut line extending from the front surface of the paperboard to an intermediate position in the thickness direction and a half-cut line extending from the back surface to the intermediate position in the thickness direction. Are arranged so as to be displaced substantially in parallel with each other, and a structure is provided in which a space between these half-cut lines is delaminated to open. A third aspect of the present invention is characterized in that, in addition to the configuration of the first or second aspect of the present invention, a configuration is provided in which a tool or tool is housed inside a carton having a transparent portion.

[0006]

According to the first aspect of the present invention, the opening knob is arranged so that the opening direction of the opening knob intersects the grain direction of the paperboard, and the grain direction of the paperboard and the zipper are arranged substantially in parallel. When the pinch is gripped and pulled away from the carton, at the initial stage of opening, a breaking force is applied in a direction perpendicular to the paper grain direction, which is the direction of the cut line of the score line,
Since the resistance required to tear the zipper from the score line along the grain direction to the zipper is much smaller than the resistance required to tear it, the tear line is not torn in the direction in which the score line extends and the score line is not cut. From the zipper along the grain direction. According to a second aspect of the present invention, the zipper according to the first aspect further comprises:
A half-cut line from the front surface of the paperboard to the middle position in the thickness direction and a half-cut line from the back surface to the middle position in the thickness direction are arranged at positions substantially parallel to each other, and delaminated between these half-cut lines. With the addition of a configuration that opens with the opening knob, the opening handle of the opening knob is smoothly broken from the cut line to one of the half-cut lines that are linearly continuous along the grain direction. The other is also smoothly broken through the substantially L-shaped bent portion. According to the third aspect of the present invention, a configuration in which a tool or a tool is housed inside a carton having a transparent portion is added to the configuration of the first or second aspect, so that a user can pass through the transparent portion through the carton. Tools or tools can be checked.

A part of the left and right side surfaces A2 and A3 and a top surface A5 constitute a transparent portion that can be seen through.

Further, a plurality of projections 7 for preventing falling are connected to the lower edges of the front face A1 and the rear face A4 located at the lower end of the carton A in the assembled state.

Next, a method of opening the carton with the opening zipper will be described. First, in the state shown in FIG. 1 (a), when the user holds the opening knob piece 2 and pulls it away from the cylindrical body of the carton A, in the initial stage of the opening, the opening portion 1a of the cut line 1 extends in the direction of the slit extension. A certain grain direction G
A breaking force acts in a direction perpendicular to the direction.

However, compared to the resistance required to tear in the direction perpendicular to the grain direction G, the score line 1
The resistance required for tearing the zipper 3 along the grain direction G from the outlet 1c is much smaller.

As a result, as shown in FIG. 1B, the cut line 1 is not torn in the direction in which the entrance 1a of the cut line 1 extends.
The paperboard P is smoothly torn from the exit 1c of the cut line 1 along the grain direction G to the zipper 3 and then torn along the zipper 3 to the lower edge of the back panel A41,
It becomes completely separable from the sealing portion A43. At substantially the same time, the breaking line 5 located between the back panel A41 and the glue flap A51 attached to the top surface A5 is also broken, so that the back panel A41 can be opened.

As a result, at the initial stage of opening, a cut can be made along the zipper 3 from the cut line 1 without displacing, so that the cut can be neatly opened and opened.

In this embodiment, parallel half-cut lines 3a and 3b extending from the front and back surfaces of the paperboard P to the middle position in the thickness direction are used.
Since the zipper 3 having a structure for separating the layers between layers is used, the opening half of the front side which is linearly continuous along the grain direction G from the exit portion 1c of the cut line 1 with the opening operation of the opening knob piece 2. The wire 3a is smoothly broken into a line 3a, and is also smoothly broken through a substantially L-shaped bent portion 3c into a half-cut line 3b on the back side.
The layers located between b are peeled off.

As a result, even if the zipper 3 is torn in a direction intersecting the opening direction, the zipper 3 can be neatly broken without displacement from the cut line 1 along the zipper 3. Further, when the reclosing means 4 recloses, the delaminated portion 3 between the two half-cut lines 3a and 3b is formed.
d is not exposed on the surface side of the carton A.

In this example, an experiment was performed to compare the force required for opening with other opening structures. In this experiment, a carton (assembled) of the present embodiment indicated by A and a carton of a comparative sample having the same structure as that of the present embodiment indicated by B and the grain direction G of the paperboard P orthogonal to the zipper 3 were used. (Assembled) were prepared for each of the three points. For the experimental equipment, an autograph tensile tester was used.
It was pulled at 00 mm / min and the maximum strength required for opening was measured. The results are shown in Table 1 below.

[0029]

[Table 1]

From the above experimental results, the grain direction G of the paperboard P
The zipper 3 is arranged along the
It was verified that Example Sample A of the present invention, which had a half-cut structure from the front and back surfaces P1 and P2, required less force to open. Further, in Example Sample A of the present invention, since the zipper 3 is first peeled off over the entire length as a result of the small force required for opening, all of the opening force is concentrated on the opening start end of the breaking line 5, whereby After the zipper 3 was completely peeled off, the back panel A41 was easily and cleanly torn along the breaking line 5. On the other hand, in the comparative sample B, the zipper 3 is hard to be peeled off, and further, stress is applied to the corner of the opening knob piece 2 and the corner is broken in the paper grain direction.
Turned out not to cut at all. As described above, not only the numerical values of the opening strength but also the actual opening function of the comparative sample B was incomplete, but the sample A of the example of the present invention completely exhibited the desired opening function.

Further, from the user's point of view, the tools or tools housed in the carton A can be seen through the transparent portion formed by the transparent cover C, so that the carton A can be easily opened without opening the carton A. It can be confirmed. This tool or tool is particularly effective when a product such as a hair dyeing product set with accessories such as combs, gloves, and instruction manuals is stored in addition to the hair dye. As a result, a sense of security can be given to the user.

In the embodiment described above, the top surface A of the carton A is
5 and the bottom surface A6 are formed in a semi-cylindrical shape, and are curved in a semi-cylindrical shape from the front surface A1 to the left and right side surfaces A2 and A3, but are not limited thereto, but not shown, but the top surface A5 and the bottom surface A6 of the carton A. May be formed in a rectangular shape, and may be bent in a rectangular shape from the front surface A1 to the left and right side surfaces A2 and A3.

Further, in the above-described embodiment, the case where the zipper 3 has a structure in which the parallel half-cut lines 3a and 3b extending from the front and back surfaces of the paperboard P to the middle position in the thickness direction are peeled off and opened. However, the structure of the zipper 3 is not limited to this, and another structure such as a sewing rule shown in FIG. 5 or a structure similar thereto may be used.

Further, although one cut line 1 is cut along the lower portion of the opening knob 2, the present invention is not limited to this. Two cutting lines 1 are cut so as to sandwich the opening knob 2, and both cut lines are cut. The wires 1 may be provided on the zippers 3 respectively. Furthermore, the case where the carton A is assembled with a composite blank in which the paperboard P and the transparent cover C are bonded is shown, but the present invention is not limited to this, and the carton A may be configured with only a paperboard blank.

[0035]

As described above, according to the first aspect of the present invention, the opening direction of the opening knob piece is arranged to intersect with the grain direction of the paperboard, and the grain direction of the paperboard and the zipper are arranged. By placing the opening knob piece and pulling it away from the carton by placing the opening knob piece approximately in parallel, a breaking force acts in a direction perpendicular to the paper grain direction, which is the extension direction of the cut line of the cut line, at the initial stage of opening. However, the resistance required to tear the zipper from the score line to the zipper along the grain direction is much smaller than the resistance required to tear it, so that it is not torn in the direction of the cut line extension of the score line. Since it is smoothly broken from the cut line to the zipper along the direction of the grain, it can be broken cleanly without displacement from the cut line along the zipper. Therefore, compared with the conventional one in which the opening direction of the opening knob piece and the paper grain direction of the paperboard are arranged in parallel and the paper grain direction of the paperboard and the zipper intersect, the cuts enter finely along the zipper and are opened successfully. it can.

According to a second aspect of the present invention, in addition to the effect of the first aspect of the present invention, any one of the semi-cut lines which are linearly continuous from the cut line along the direction of the grain along with the opening operation of the opening knob piece. Since it is smoothly broken to one side and the other is smoothly broken through the substantially L-shaped bent part,
Even when the zipper has a structure in which the zipper is torn in a direction intersecting the opening direction, the zipper can be neatly broken without being displaced from the cut line along the zipper.

According to the third aspect of the present invention, in addition to the effects of the first or second aspect, since the user can check the tools or tools in the carton through the transparent portion, the user can feel a sense of security. Can be given.
