  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described in detail with reference to the accompanying drawings. Note that the same number is assigned to the same element throughout the description of the embodiment.

<First Embodiment>
1st Embodiment of the film package which concerns on this invention is described referring FIGS. 1-5. As shown in FIG. 1, the film package 10 includes a packaging bag 11 formed of a flexible film, and a temporary binding portion 12 provided on the upper surface 11 a of the packaging bag 11 in the longitudinal direction X. As will be described in detail later, the temporary binding portion 12 includes left and right end sections 12a and 12a formed by single-line perforations and a central section 12b formed by single-line perforations.

  First, the packaging bag 11 will be described. The packaging bag 11 is a film packaging bag formed by sealing the both ends 11b in the longitudinal direction X by heat sealing or the like in a state in which the article to be packaged P is housed in a flexible film formed in a cylindrical shape. It is. Since the film packaging bag is formed in a substantially rectangular parallelepiped shape having a gusset as shown in FIG. 1, it is suitable for storing a bundle of sanitary paper as the packaged item P.

  As the flexible film constituting the packaging bag 11, a polyethylene (PE) resin film or a polypropylene (PP) resin film can be suitably used. In addition, for example, this type of packaging bag such as a polyethylene terephthalate resin film. The general thing used for 11 can be used. The flexible film may be a laminate film obtained by laminating several films, or may be a film made of a mixed resin thereof.

As thickness of the flexible film which comprises the packaging bag 11, it is preferable that the thickness measured based on JISP8118 shall be 30-50 micrometers. When the thickness of the flexible film is less than 30 μm, there is a problem of insufficient strength, and when the thickness is more than 50 μm, there is a problem of high cost. When a flexible film is formed with a polyethylene (PE) resin film, the basis weight that can ensure the above-mentioned thickness is 27.3 to 46.3 g / m ^{2 for} low density PE and medium density PE. if 27.8~47.0g / ^{m 2,} a 28.2~48.3g / ^{m 2} if high density PE. Moreover, when forming a flexible film with a polypropylene (PP) resin film, the basic weight which can ensure the above-mentioned thickness is 26.4-45.0 g / m < ² > if it is unstretched, and if it is stretched. 27.2-45.3 g / m ² .

  As shown in FIG. 2, the packaging bag 11 contains a packaged object P made of sanitary paper folded in a pop-up manner, and has a rectangular parallelepiped shape as a whole. The package P is sanitary paper such as tissue paper, toilet paper, kitchen paper, paper hand towel, paper towel, and wiper, and any of them may be used.

  Briefly describing the pop-up type, the sanitary paper is alternately folded in the vertical direction, and when one sanitary paper is taken out, a part of the next sanitary paper is pulled out from the opening for taking out. To fold sanitary paper in a pop-up style, ply up (double stack) large base paper as necessary, then combine multiple narrow rolls cut to a predetermined width and fold Multi-folding method can be used, or it is possible to use a multi-folding method in which large width paper is plied up as necessary, the roll is cut to a predetermined width, and then folded with one or two narrow rolls. It may be based on the method.

  As general dimensions of the bundle of sanitary paper, the length in the longitudinal direction X is about 180 to 250 mm, the length in the lateral direction Y is about 80 to 115 mm, and the length in the vertical direction is about 30 to 110 mm. Accordingly, the storage space of the packaging bag 11 has a length in the longitudinal direction X of about 105 to 130% and a length in the short direction Y of about 100 to 120% with respect to the size of the bundle of sanitary paper. The length in the direction is preferably about 100 to 120%. When the lengths in the longitudinal direction X and the short direction Y are within this numerical range, the contact portion between the bundle of sanitary paper and the inside of the packaging bag 11 is reduced, the packaging bag 11 is easily bent, and the bundle of sanitary paper. The position of the opening 13 tends to be lowered following the height. If the length in the vertical direction exceeds 120%, the packaging bag 11 is greatly bent before the sanitary paper is used, so that the packaging bag 11 has a tab and it is difficult to take out the sanitary paper.

  Next, the temporary binding part 12 is demonstrated. As shown in FIG. 1, the temporary binding portion 12 is provided on the upper surface 11a of the packaging bag 11 so as to extend from one side to the other side in the longitudinal direction X, and is formed by a single line perforation. It is composed of partial sections 12a and 12a and a central section 12b formed by a single perforation. Here, an example is shown in which the left and right end sections 12a, 12a are provided within the range of the upper surface 11a of the packaging bag 11, but the left and right end sections 12a, 12a are the left and right sides of the upper surface 11a of the packaging bag 11. You may extend to the both ends 11b of the longitudinal direction X beyond an end.

  The end sections 12 a and 12 a and the center section 12 b can both break the perforation by applying a force toward both ends in the short direction Y of the packaging bag 11. As will be described in detail later, as shown in FIG. 3, only the central section 12b can be broken to provide the opening 13 without breaking the perforated end sections 12a and 12a constituting the temporary binding section 12. it can. In this way, even if the sanitary paper is stored in the packaging bag 11, the next sanitary paper drawn after the preceding sanitary paper is taken out may stop in a state where a part is exposed to the outside from the opening 13. It does not fall into the space inside the packaging bag 11. In addition, the opening here refers to a narrow space formed when a single line perforation such as the end sections 12a and 12a is broken when it is composed of a single line, and if necessary, a cut (or (Slit). On the other hand, when it consists of double lines as will be described later, it indicates a wide space such as the opening 13 formed when the perforation of the double line such as the central section 12b is broken.

  With reference to FIG.4 and FIG.5, the temporary binding part 12 of 1st Embodiment is demonstrated in detail. As described above, the temporary binding portion 12 has the left and right end sections 12a and 12a and the central section 12b sandwiched between them, and the central section 12b further includes a first central section 12b1 closer to the center and left and right ends. Left and right second central sections 12b2 and 12b2 near the section sections 12a and 12a. In other words, the temporary binding portion 12 includes, in order from the left side, a left end section 12a, a left second central section 12b2, a first central section 12b1, a right second central section 12b2, and a right end section 12a. Has been.

  In order to change the ease of breakage for each section, the tie cut ratio between the length of the cut portion and the length of the non-cut portion is changed in the perforation constituting each section. The second central section 12b2 is set so as to be easily ruptured, and subsequently, the first central section 12b1 and the end section 12a are formed in order of easy rupture. More specifically, in the perforation forming each of these sections, when the combination of one cut part and one non-cut part is one pitch, one pitch of the second central section 12b2 is the length of the cut part. The length of the non-cut portion is 2: 1 to 1: 2. Similarly, 1 pitch of the first central section 12b1 is 1 to 1 to 6 and 1 pitch of the end section 12a is 1 to 7 to 1. It is paired 10.

  FIG. 4 does not show the actual dimensions, but shows that the pitch is different for each section, with the solid line portion of the perforation being a cut portion and the white portion being a non-cut portion. FIG. 5 shows this difference in a more easily understandable manner. In the perforation, a solid line portion is a cut portion and a white line portion is a non-cut portion, and one pitch for each section is compared. In addition, the dimension described in FIG. 5 is a numerical value as an Example mentioned later, and is not limited to these numerical values.

  Thus, by changing the ease of breakage for each section, in the first embodiment, taking the case of opening from the center in the longitudinal direction X of the center section 12 to both sides as an example, first, the center first center section When 12b1 is broken, the second central sections 12b2 and 12b2 at both ends are easily broken. Since the right second central section 12b2 and the right end section 12a have a gap in perforation pitch, that is, ease of breakage, in normal use, the right second central section 12b2 is followed by the right second central section 12b2. The end section 12 a is not broken, and only the central section 12 can be broken to form the opening 13.

  When a bundle of sanitary paper is taken out from the packaging bag 11 and transferred to the dispenser for use, the left and right end sections 12a, 12a are also broken to form slits, and the central section 12 is broken. It goes without saying that the temporary binding portion 12 can be opened over the entire length in the longitudinal direction X together with the opening 13.

Second Embodiment
Next, a second embodiment according to the present invention will be described. In the second embodiment, as shown in FIG. 6, the central section is formed in a horizontally long hexagonal planar shape by a double line perforation. Other points are the same as in the first embodiment.

  The central section 12b according to the second embodiment has a horizontally long hexagonal planar shape, and a section corresponding to a pair of left and right upper and lower sides of the horizontally long hexagon has left and right second central sections 12b2 and 12b2. The section sandwiched between the second central sections 12b2 and 12b2 constitutes the first central section 12b1. A pair of left and right sides of the horizontally long hexagon, that is, the left and right second central sections 12b2 and 12b2 expand toward the first central section 12b1 and close toward the left and right end sections 12a and 12a. Yes. Thereby, coupled with changes in the pitches of the cut and non-cut portions of the perforation, the left and right second central sections 12b2 and 12b2 are suitable triggers when one of them is first broken, and to the other end. Even if it breaks, the perforations in the end sections 12a, 12a are not subsequently broken, and only the perforations in the central section 12b can be broken to form the openings 13. That is, the second central section 12b2 on the left side is easily broken first, and then the second central section 12b2 on the right side is easily broken via the first central section 12b1.

<Third Embodiment>
Next, a third embodiment according to the present invention will be described. In the third embodiment, as shown in FIG. 7, the central section is formed as a horizontally long rhombus with double-line perforations. Other points are the same as in the second embodiment.

  The central section 12b according to the third embodiment has a horizontally long rhombus planar shape, and the sections corresponding to the left and right ends of the two sides of each pair of the left and right sides of the horizontally long rhombus are the left and right second central sections 12b2, 12b2. A section sandwiched between the second central sections 12b2 and 12b2 constitutes a first central section 12b1. The left and right ends of each pair of left and right sides of the horizontally long rhombus, that is, the left and right second central sections 12b2 and 12b2 expand toward the first central section 12b1 and toward the left and right end sections 12a and 12a. Blocked. Thereby, coupled with the change in the ratio of the cut portion and the non-cut portion of the perforation, the left and right second central sections 12b2 and 12b2 become a suitable trigger when one of them is first broken, and to the other end. Even if it breaks, the perforations in the end sections 12a, 12a are not subsequently broken, and only the perforations in the central section 12b can be broken to form the openings 13.

Next, a fourth embodiment according to the present invention will be described. In the fourth embodiment, as shown in FIG. 8, the central section is formed to be elliptical by a double line perforation. Other points are the same as in the second embodiment.

  The central section 12b according to the fourth embodiment has a horizontally long elliptical planar shape, and the sections corresponding to the left and right circular arcs on the long axis side of the elliptical form the left and right second central sections 12b2 and 12b2. A section sandwiched between the second central sections 12b2 and 12b2 constitutes a first central section 12b1. The elliptical left and right arcs, that is, the left and right second central sections 12b2 and 12b2 expand toward the first central section 12b1 and close toward the left and right end sections 12a and 12a. Thereby, coupled with the change in the ratio of the cut portion and the non-cut portion of the perforation, the left and right second central sections 12b2 and 12b2 become a suitable trigger when one of them is first broken, and to the other end. Even if it breaks, the perforations in the end sections 12a, 12a are not subsequently broken, and only the perforations in the central section 12b can be broken to form the openings 13.

<Fifth Embodiment>
Next, a fifth embodiment according to the invention will be described. In the fifth embodiment, as shown in FIG. 9, the central section is formed in an oval shape with double-line perforations. Other points are the same as in the second embodiment.

  The central section 12b according to the fifth embodiment has a horizontally long oval (rounded rectangular) planar shape, and sections corresponding to the oval left and right arcs are the left and right second central sections 12b2 and 12b2. The section sandwiched between the second central sections 12b2 and 12b2 constitutes the first central section 12b1. The oval left and right arcs, that is, the left and right second central sections 12b2 and 12b2 expand toward the first central section 12b1 and close toward the left and right end sections 12a and 12a. Thereby, coupled with the change in the ratio of the cut portion and the non-cut portion of the perforation, the left and right second central sections 12b2 and 12b2 become a suitable trigger when one of them is first broken, and to the other end.
