Abstract

PROBLEM TO BE SOLVED: To solve directional property on tear-off operation and to smoothly tear off a seal even when the tear-off operation is started from either of both end parts of a zipper, by providing two lines of intermittent long straight incisions along the tear-off direction and short straight incision lines crossing at right angles in the tear-off direction on both end parts thereof. SOLUTION: Intermittent long straight tear-off lines 11 in two rows are incised regularly at the same phase along the tear-off direction. In addition, short straight tear-off lines 12 crossing at right angles in the tear-off direction are incised on both end parts of each long straight tear-off line 11 and a zipper C is formed between two rows of these tear-off lines 11 and 12. The zipper C can be torn off from either of both ends, a right end tab C or a left end tab C and the tab C is raised by pinching it with fingers and is pulled upward as it is to act a straight scission force toward the tear-off direction through the teat-off lines 11 in the teat-off direction and to break the first connected part 12a. Thereafter, the zipper C is made into a belt-like shape to successively break the connected parts 12a and to tear off a paper carton A.

2. Description of the Related Art Cutting lines and zippers (opening strips) for opening paper containers, which are cut and provided on the outer surface of the structure of paper containers for packing various articles such as various foods, confectioneries, and other daily necessities, are provided. Conventionally, for example, as shown in FIGS. 5A to 5D, there are various patterns as cut lines cut in a line, and FIG. 5A shows the outer peripheral surface of the upper part of the structural side plate of a hexahedral paper container A. A cutting line B, (b) in which a bending line formed by a combination of a horizontal line 1 and an oblique line 2 at one end thereof is intermittently cut in a line, is a wavy line 3 on the outer peripheral surface of the upper part of the peripheral side plate of the cylindrical paper container A. The cutting lines B and (c) which are intermittently cut in a line so that both ends thereof overlap each other are arranged on the outer peripheral surface of the upper part of the structural side plate of the hexagonal cylinder-shaped paper container A. The bending line by the combination of the angled oblique lines 2 and 2 was cut off intermittently in a line. Write line B, and (d), score line B that Kokusetsu to intermittently a row of continuous waveform 4 on the outer peripheral surface of the structural plate top of the paper container A hexahedron shape.

As shown in FIGS. 6 (a) to 6 (e), for example, there are various patterns as zippers (opening strips) cut in two rows, and (a) shows Y patterns on the outer peripheral surface of a paper container. The zippers C and (b), in which the letter-shaped lines 5 are intermittently cut in two rows at the same phase, are intermittently bent in two rows on the outer peripheral surface of the paper container by the combination of the horizontal line 1 and the oblique line 2 at one end thereof. The zippers C and (c) cut in the same phase are intermittently bent in two rows on the outer peripheral surface of the paper container by a combination of a horizontal line 1, a diagonal line 2 at one end thereof, and a vertical line 6 bent at a right angle at the other end. The zippers C and (d) cut in the same phase are T-shaped lines formed by combining the horizontal line 1 and the vertical line 7 connected to one end thereof on the outer peripheral surface of the paper container in two rows intermittently at the same phase. The chopped zippers C and (e) are horizontal lines 1 on the outer peripheral surface of the paper container.
A zipper C is formed by intermittently cutting a curved line 8 in two rows into a U-shape.

The conventional score line B shown in FIGS.
The zipper C having a band shape, particularly the zipper C having various patterns shown in FIG. 6, is designed to break the outer surface of the paper container structure by pulling one end of the zipper C up in the direction of the arrow and opening the zipper C. The zipper has an orientation that is easy to open in one direction, and an arrow is printed or displayed on the surface of the container near the arrow-side end of these zippers,
The letter "N" is printed and displayed to indicate the opening direction.

[0005] However, even if the container A is instructed to open in this manner, if the container A is inadvertently opened from the opposite direction, or if an infant or a blind person,
In some cases, it is difficult to recognize the indication of the opening direction, and in such a case, it is difficult to open the container.

Therefore, there are opening zippers having no opening direction as shown in FIGS. 7 (a) to 7 (c). FIG. 7 (a) shows a horizontal line 1 and an oblique line at one end on the outer peripheral surface of a paper container. As shown in the figure, the zippers C and (b) in which the bending lines formed by the combination of the horizontal lines 1 and 2 are intermittently cut in the same phase in two rows are bent by the combination of the horizontal line 1 and the diagonal line 2 at one end on the outer peripheral surface of the paper container. The zippers C and (c) in which the lines are intermittently cut in the same phase in two rows so as to face each other have two wavy lines 9 formed by alternately combining convex curved lines and concave curved lines on the outer peripheral surface of the paper container. A zipper C is intermittently cut into a row at the same phase.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the directionality in the opening operation of a paper container as described above, so that opening can be performed smoothly even when opening operation is started from either end of the zipper. It is in.

[0008]

SUMMARY OF THE INVENTION The present invention provides a long straight cut line 11 intermittently and intermittently arranged in two rows at the same phase along the opening direction. A paper container opening zipper, comprising a short straight cut line 12 perpendicular to the opening.

BEST MODE FOR CARRYING OUT THE INVENTION
FIG.
FIG. 2 is a plan view of the paper container opening zipper of the present invention formed on the upper plate of the paper container A (paper container), in which a long straight cut line 11 intermittently intermittently arranged in two rows at the same phase along the opening direction. It is chopped.

A short straight cut line 12 perpendicular to the opening direction is cut at both ends of each long cut line 11, and a zipper is provided between the two rows of cut lines 11, 12. C
Are formed.

Short cut lines 12, 12 perpendicular to the adjacent opposing long cut lines 11, which are cut at both ends of each long cut line 11, are separated from each other in parallel. The separated portion is the connecting portion 12a before being opened.

The zipper C of the present invention may be any one of the constituent plates of the structure constituting the paper container A, for example, any of a top plate, a side plate (a front plate, a back plate, a right and left side plate, etc.), or a bottom plate. For example, among the constituent plates, the side plates are provided continuously on the entire periphery of some or all of the side plates.

Further, a short straight cut line 12 perpendicular to the opening direction is not cut at the outer end of each long cut line 11 forming both ends of the zipper C. Opening tab C with two rows of cutting lines
_1, and C _1. The outer ends of the opening tabs C ₁ , C ₁ may be formed so as to slightly protrude from the edge of the component plate (top plate), if necessary. _1, constituting plate outer ends of the C ₁ to the front opening operation (upper plate)
A slight connecting portion 11a (not-cut portion) for connecting to may be formed.

[0014] The zipper C of the present invention can open from both the right end of the tab C ₁ or leftmost tab C ₁ in FIG. 1, raised up by pulling the tab C ₁ with a finger, by directly pulling upwards, opening A linear cutting force directed in the opening direction by the cut line 11 in the direction acts on the first connecting portion 12.
a, and then the next connecting portion 12a is broken by a linear cutting force in the opening direction by the cutting line 11 in the next opening direction, and the zipper C becomes a band and sequentially connects the connecting portions 12a. Break and open the paper container A.

FIG. 2 is a partially enlarged plan view of the zipper C of the present invention, in which the length of the long cut line 11 is a, the distance between the short cut lines 12 and 12 opposed to each other in parallel is b, and the length is long. Short cut line 12 projecting from cut line 11 at right angles to both sides
When the overhang length is c (the length 2c of the short cut line 12), it is appropriate to set the relationship such that a> (2b to 3b) and b ≧ c are satisfied.

For example, as an example, the length a of the long cutting line 11 is 7 mm, the length of the short cutting line 12 is 2c = 4 mm, and the separation distance b between the short cutting lines 12 and 12 is set to 2 to 2.5 mm. You.

When the above values are set, the pulling force of the zipper C required for unsealing at the time of unsealing is the same as when a normal carton paper (paper thickness: about 0.2 mm to 0.25 mm) is used. , A tensile force corresponding to a pressing force of about 350 g / m ² is obtained, and the tensile force of the zipper C increases in proportion to the magnitude of the separation distance b.

FIG. 3 is a perspective view showing an embodiment in which the zipper C of the present invention is cut on the upper plate 21 of the paper container A.
The paper container A includes a top plate 21, four side plates 22, 23, 24, 2
5, constituted by the bottom plate 26, the opening direction need not be displayed at both ends of the zipper C, but the opening direction display 13 such as an arrow may be shown as shown.

FIG. 4A is a perspective view showing another embodiment in which the zipper C of the present invention is cut on the upper plate 21 of the paper container A. The paper container A is provided at both ends in the longitudinal direction of the zipper C. Both ends 21a, 21a of the corresponding upper surface plate 21 have a V-shaped cut upper surface plate 21 and four side plates 22, 23,
24 and 25 and a bottom plate 26.

In the structure of the paper container A, as shown in FIG. 4 (b), the upper surface of the upper plate 21 cut with the zipper C is connected to the upper portion of the side plate 24 folded into the lower surface of the upper plate 21. In the case of the paper container A having a structure in which a slight step d (for example, about 1 mm) is provided between the upper surface of the folded flap plate 24a and the upper surface of the upper surface plate 21, both end tabs C ₁ and C _{1 are provided.} If, in a step is formed between the upper surface of the folding flaps 24a, the position of the tab C ₁ in folding carton a, can be accurately confirmed by feel.

[0021]

The paper container opening zipper of the present invention can be opened smoothly even if the opening operation is started from either end of the zipper, and the opening direction of the zipper in the opening operation of the paper container can be eliminated. As with conventional zippers with directional opening, the difficulty of inadvertently opening the zipper has been resolved, so that even infants and visually impaired persons can open without opening direction indications. By simply confirming the position of the zipper, there is an effect that the zipper can be opened smoothly even if the zipper is opened from any direction.
