Description

  The present invention relates to a packaging bag for paper hygiene articles.

Conventionally, a packaging bag made of a film body such as a polyethylene film, in which a plurality of paper hygiene articles such as toilet paper, kitchen paper, etc., such as twelve or sixteen, are stacked and packaged as one pack. It has been known.
The schematic diagram of the packaging method of the paper hygiene article by the conventional packaging bag is shown to Fig.7 (a)-(d).
The film packaging bag is provided with a grip portion in advance before a roll-like paper hygiene article such as toilet paper is inserted (see FIG. 7A). After the toilet paper is inserted along the longitudinal direction of the packaging bag (see FIG. 7B), the opening is sealed (see FIG. 7C), and the bottom of the packaging bag is It is formed (see FIG. 7D).
It is desirable that the packaging bag for storing such a roll-like paper hygiene article is easy to open while maintaining the strength to support the load of the paper hygiene article when the purchased consumer carries it.
For this reason, for example, by forming a perforation for opening in advance above a finger hook hole for hooking a finger when carrying it, the packaging bag will not be accidentally broken when the consumer carries it. A technique that can be opened with a small force is proposed (for example, Patent Document 1). In addition, a technique has been proposed that makes it difficult for a finger that a consumer hangs on a finger hook hole to carry when carrying (for example, Patent Document 2).

), The bag body 20 for storing the roll paper, the substantially rectangular gripping part 3 formed by bonding one end of the film body 2, and the other end of the film body 2 are fused. The bottom 4 is formed. In the following description, the direction in which the roll papers are stacked is the longitudinal direction (Z direction) of the packaging bag 1, the direction orthogonal to the longitudinal direction and the plane along the plane of the grip portion 3 is the width direction (X direction). And the direction orthogonal to the longitudinal direction and the width direction is the depth direction (Y direction). The description will be made assuming that the grip portion 3 side is the upper end side and the bottom portion 4 side is the lower end side.
In addition, as paper hygiene articles, absorbent articles such as cartons, tissue diapers, absorbent pads, sanitary products, and the like, in addition to roll paper such as toilet paper and paper towels, are included. In the following description, a paper hygiene article will be described as a toilet paper P as an example.

The packaging bag 1 is formed, for example, by forming a pair of gusset folds (see FIG. 2 (a)) that folds inward along the Z direction of the tubular film body 2 (2a to 2d). Thus, when the lower end side is fused and the toilet paper P is stored, a portion that becomes the bottom portion 4 is formed (see FIG. 3A). Then, the toilet paper P is inserted along the Z direction of the packaging bag 1 (see FIG. 3B), and the upper end side of the packaging bag 1 which is folded in gusset is bonded with halftone dot heat embossing to form the grip portion 3. (See FIG. 3C).
More specifically, as shown to Fig.2 (a), the film bodies 2c and 2d of the side surface of the packaging bag 1 are gusset-folded at the lower end part of the packaging bag 1, for example. The gusset-folded film bodies 2c and 2d are folded and fused to the film bodies 2a and 2b. The fused lower end side functions as the bottom portion 4 when the toilet paper P is stored (see FIG. 3D). Note that the method of fusing the bottom 4 is not limited to gusset folding, and for example, a fusing method such as three-side seal, pillow packaging, standing pouch, etc. may be applied, and toilet paper stored in the packaging bag 1 Any method can be used as long as it can secure a sufficient fusion strength to withstand the load of P. Thereby, the bottom part 4 can ensure the fusion strength more than twice the weight of contents such as the toilet paper P stored in the packaging bag 1. Here, fusion refers to fusion bonding such as heat sealing or ultrasonic sealing.

  As shown in FIG. 1, the grip portion 3 is provided at a pair of finger hook holes 3 a and 3 a provided along the X direction in the vicinity of the approximate center of the grip portion 3 and at one end portion of the packaging bag 1 in the X direction. The cut body 3b and the film bodies 2c and 2d on the side surface of the packaging bag 1 are gusset-folded, the opposing film bodies 2a and 2b fold the film bodies 2c and 2d, and the finger hook holes 3a and 3a of the grip section 3 And a bonding portion 3c bonded by dot heat emboss bonding provided in a predetermined region including

  As shown in FIG. 1, two finger hooking holes 3 a and 3 a are provided at predetermined positions of the grip portion 3. Specifically, the finger hooking holes 3 a and 3 a are arranged at substantially equal positions in the X direction along the plane of the grip portion 3 from the approximate center of the grip portion 3. Moreover, a part of edge part of each finger hook hole 3a, 3a is melt | fused. Thereby, the strength of the finger hooking holes 3a and 3a is increased, and when carrying the packaging bag 1 in which the toilet paper P is stored, it can be prevented from being torn by the force applied to the finger hooking holes 3a and 3a. In addition, the part made to melt | fuse in the edge part of the finger hook holes 3a and 3a may be changed according to the load of the toilet paper P to accommodate, and the whole edge part may be fused.

  The cut portion 3b is a cut portion formed so as to cut into one end portion of the grip portion 3 in the X direction. Specifically, as shown in FIG. 2 (b), the cut portion 3b is provided so as to be positioned at substantially the same height as the lower end side of the edge portion of the finger hooking holes 3a, 3a. In addition, although the cut part 3b was demonstrated to provide in the one end part of the X direction of the holding part 3, you may provide so that it may become a pair in the both ends of the holding part 3. FIG.

The adhesion part 3c is an adhesion part where the opposing film bodies 2a and 2b are adhered by dot adhesion with the gusset-folded film bodies 2c and 2d interposed therebetween. For example, the adhesion part 3c is adhere | attached so that peeling is possible by carrying out heat embossing adhesion | attachment (halftone dot heat embossing adhesion | attachment) in the shape of dots, such as a dot and a short line. Here, halftone dot heat embossing is an adhesion method in which a predetermined pressure-bonding process is applied in a halftone dot shape to heat-seal the opposite surface, and it is made to adhere rather than melt-fusion such as heat sealing or ultrasonic sealing. This is a bonding method capable of easily peeling the opposite surface.
