Description

  The present invention relates to a packaging bag, and more particularly to a packaging bag optimal for stacking and packaging a plurality of roll-type toilet paper.

  Roll-type toilet paper is usually stored in a plastic film bag as 12 three-tiered stacks of four in a row, or six total of three-tiered stacks of two in one row. It is made to be done.

  As shown in FIG. 9, the packaging is generally folded inward at both sides in the longitudinal direction to close the bottom end of a cylindrical plastic film b on which gussets a and a are formed by heat sealing to form a bottom c, and a predetermined inside. After storing a number of roll-type toilet papers d, d ..., the upper end is heat-sealed to form a flat hand-carrying part e, and hand-carrying holes f, f for holding the hand-carrying part e with fingers are formed by punching However, it is designed to be carried by hand.

  Thus, in the packaging form packaged as described above, as shown in FIG. 9, the top surface portions h and h that are inclined downward from the hand-carrying portion e to the shoulder portions g and g of the bag are formed.

  When taking out the toilet paper d packaged as described above, the toilet paper d is generally taken out by cutting the vicinity of the lower end of the hand-carrying part e with a jar j or a cutter and breaking the upper part of the bag. .

  However, since the gussets a and a exist even if the top surface h is cut, it is difficult to fully open it at one time, and it is necessary to cut several times, so that not only a troublesome work is forced. Even when the toilet paper d remaining in the bag is stored, the upper portion of the bag is disturbed and cannot be wrapped and stored.

  In addition, in order to maintain the strength of the bag when hand-held after packaging, if a stretched film stretched in the vertical direction is used for the film constituting the bag, it is difficult to cut in the lateral direction at the time of opening. The opening operation will be troublesome.

With regard to these points, the same can be said for packaging of articles of similar form as well as packaging of roll-type toilet paper.

  It is an object of the present invention to provide a packaging bag that can perform the operation of opening the packaging bag of the above-described form and taking out the contents without losing the strength as the bag. To do.

  As a means for solving the above-mentioned problems, the present invention provides a packaging bag made of a plastic film stretched in the vertical direction in which one end is closed and the contents are packed and sealed from the opening at the other end to form a package. A perforation for breaking from the laterally central position of the handbag toward both sides of the shoulder in a region of the top surface that is symmetrically inclined from the handbag formed by sealing the shoulder to the shoulder of the package The line is formed in a substantially mountain shape, and the perforation is broken and opened in a substantially triangular shape.

  The packaging bag may be configured to have a gusset that is folded inward on both sides in the longitudinal direction, and the body portion of the packaging bag bulges into a square shape, which can be suitable for packaging angular contents. .

  As described above, the perforations arranged in a triangular shape are each divided into a plurality of regions, and the divided perforation rows are bulged outward from the triangle from the handbag side to the shoulder. Preferably, the perforation row is formed in an arc shape so that the overall length of the perforation line is substantially increased, and the hand-carrying portion side is formed into an arc having a small radius, and the arc is formed so that the radius increases toward the shoulder portion.

  The arc-shaped perforation row has an upper half portion as a transverse component intersecting the stretching direction running in the vertical direction of the plastic film constituting the packaging bag, and a lower half portion being a longitudinal component substantially parallel to the stretching direction. As described above, the packaging bag can be easily cut in the lateral direction where it is difficult to cut, and the vertical direction in which the packaging bag is easy to cut can be configured so as not to deteriorate the strength.

  From this point, the arc-shaped perforation line is formed such that the cuts in the horizontal component area are short, the interval portion between the cuts is formed longer than the cuts, and the cuts in the vertical component area are longer than the cuts in the horizontal component area. It is preferable that the interval portion between the cuts has substantially the same length as the interval portion of the lateral component region.

  It is preferable that the perforation cuts located at the connecting portions of the arcuate perforation rows be formed longer than the other cuts, since each arcuate perforation row can be smoothly cut.

  According to the present invention, the uppermost perforation row close to the hand-holding portion is cut with fingers, and the left and right perforations forming the mountain shape in the upper top surface region of the package are successively broken to form a substantially triangular shape. Since the upper package body of the packaged contents is opened widely, the contents can be easily taken out, and after removing the required amount, the roughly triangular cut piece serves as the cover. Can be stored without losing appearance.

  If gussets are formed on both sides of the packaging bag in the up-down direction, even an angular content such as roll-type toilet paper can be neatly packed.

  If the perforation line formed in the top surface region of the packaging bag is constituted by a series of arc perforations, the upper half and the lower half of each arc perforation have a horizontal component and a vertical component, respectively. Therefore, even if the perforation line is continuous from the hand-carrying portion to the shoulder portion of the package, it is prevented from breaking due to the weight of the contents.

  By selecting the length of the arc perforation and the length of the interval between the perforations, the perforation can be easily cut and difficult to cut.

  In particular, by configuring the perforation row by a series of a plurality of circular arc perforation rows, the overall length of the perforation row can be made substantially longer, and in this respect also, it is difficult to break due to external force factors. Can do.

  The present invention is effective as a general packaging bag, but is particularly suitable as a packaging bag for packaging a plurality of roll-type toilet papers in a stacked form.

  FIG. 1 is a front view of the packaging bag according to the present invention when not in use, and FIG. 2 is a schematic cross-sectional view taken along the line Y-Y in FIG. 1. This packaging bag 1 is made of a synthetic resin such as polyethylene or vinyl chloride. It is made from a continuously manufactured cylindrical plastic film.

  As this film, a stretched film stretched in the axial direction is used.

  Both sides in the axial direction of the tubular film are folded inward to form gussets 2 and 2, and the packaging bag 1 is formed by fusing for each bag length.

  At the time of fusing, one end is sealed to form the bottom portion 3, and the other end is sealed as a hand-held portion 4 having a required width after the contents are packed. The hand-held portion 4 is formed with punch holes 5 and 5 for punching fingers.

  In the present invention, when the contents 6 such as a plurality of roll-type toilet papers are packaged to form the package 1A, the inclined left and right top surface areas formed from the hand-held portion 4 to the shoulder 7 of the package 1A. 8 and 8 are formed with perforation lines 9 and 9 for breakage.

  The perforation rows 9 and 9 are formed in a frontal mountain shape from the lateral center position of the hand-held portion 4 to the shoulder portion 7, and the perforation rows 9 and 9 form a triangular shape with the shoulder portion 7 as a bottom side. A cutout piece 10 (shown in FIG. 5) is formed.

  When the perforation line for breaking is formed in the top surface region 8, as schematically shown in FIG. 7, if the shoulder portion 7 is formed in a triangular shape with the bottom side, the height H of the triangle is the height of the top surface region 8. Since the vertical width is fixed, it cannot be taken large. Therefore, the length of the perforation rows 9 and 9 is shortened, and the perforation is easily broken when the handle 4 is suspended. The opening when breaking and opening is reduced.

Therefore, in the present invention, as shown in FIG. 3 and FIG. 6 as explanatory diagrams, the perforation row 9 is divided into a plurality of (three areas in the illustrated example), and the first perforation row 9 ₁ from the hand-carrying portion 4 side, A second perforation row 9 ₂ and a third perforation row 9 ₃ are provided, and the upper half portion of each perforation row 9 ₁ , 9 ₂ , 9 ₃ is defined as a transverse component region A that intersects with the film stretching direction. The half is the longitudinal component region B in the stretching direction, which is easy to cut at the time of breaking and opening, on the contrary, is difficult to break as the package 1A, and the substantial length of the perforation line is increased, resulting in a durable structure. It has a feature in that.

  In order to make the above points more effective, the cut 11 in the lateral component area A is shortened, the gap 12 between the cuts 11 and 11 is formed longer than the cut 11, and the cut 13 in the longitudinal component area B is The gap 14 between the cuts 13 and 13 is longer than the cut 11 in the directional component area A, and is approximately the same length as the gap 12 in the horizontal component area A.

  As a result, it is possible to better achieve the function of being easy to cut when broken and difficult to cut when hand-held.

Said first, second, cuts located on the third perforation row 9 _1, 9 _2, 9 ₃ joint portion of being longer than the other cuts.
