Registered Utility Model No. 3016715

  However, in Patent Document 1, since the packaging bag is broken in the vertical direction, the outlet formed in the packaging bag is not necessarily large. If the breaking length of the packaging bag is increased, the take-out port becomes larger. However, if this is done, the packaging bag does not take the shape of the bag and it becomes difficult to reuse it as a bag.

  According to the present invention, a plastic film packaging bag for packaging toilet paper rolls stacked in a plurality of stages, comprising a front surface, a rear surface, and a pair of side surfaces connected to the front surface and the rear surface, These side surfaces are folded inward and arranged between the front and rear surfaces, and a sealing portion that extends in the lateral direction is formed around the upper end of the packaging bag. A perforation formed along a pair of reference lines is formed in an intermediate part between the sealing part and the surrounding part surrounding the roll when packaging the toilet paper roll, and each reference line is formed on the side of the packaging bag. A lateral portion extending laterally and inwardly from the edge, and an inclined portion extending inward while being inclined downwardly from the inner end of the lateral portion, the inner ends of these inclined portions being perforated Are spaced from each other by the presence area, the packaging bag is provided.

  A large outlet can be formed in the packaging bag without reducing the strength of the packaging bag and maintaining the shape of the bag.

It is a top view of a packaging bag. It is a bottom view of a packaging bag. It is a perspective view of a packaged product. It is an enlarged view of a perforation. It is a figure explaining opening operation of a packaging bag.

  Referring to FIGS. 1 and 2, a packaging bag 1 for packaging a toilet paper roll has a rectangular shape elongated in the longitudinal direction L.

  The packaging bag 1 includes a front surface 2, a rear surface 3, and a pair of side surfaces 4. Each side surface 4 is connected to the front surface 2 and the rear surface 3 via a corresponding crease line 5 in the vertical direction L. Each side surface 4 is folded inward along the crease lines 4F and 5 in the longitudinal direction L, and is disposed between the front surface 2 and the rear surface 3, so that the packaging bag 1 has a flat shape. The side surface 4 functions as a gusset.

  A seal portion 6 is formed around the upper end 1U of the packaging bag 1, and the seal portion 6 extends in the horizontal direction T perpendicular to the vertical direction L. In the example shown in FIG. 1, the seal portion 6 includes a plurality of heat seal portions 7 that are spaced apart from each other. That is, the front surface 2, the rear surface 3 and the side surface 4 are integrally joined by these heat-sealed portions 7, so that the upper end of the packaging bag 1 is sealed so as to allow ventilation. The lower end 1L of the packaging bag 1 is open.

  In addition, a pair of finger-hanging portions 8 for a user to hold his / her fingers is formed at substantially the center in the lateral direction T of the seal portion 6. Each finger-hanging portion 8 is formed with a pair of semicircular cutting lines that pass from the front surface 2 through the side surface 4 to the rear surface 3. When the seal part 6 is broken by the user and the cutting lines are continuous with each other, a through hole is formed in the seal part 6. The user can carry a packaged product (described later) by placing a finger on these through holes.

  A toilet paper roll is accommodated in the packaging bag 1 through the open lower end 1L, and then the lower end 1L is sealed by, for example, heat sealing. As a result, a package P as shown in FIG. 3 is formed.

  In the example shown in FIG. 3, the toilet paper rolls R are stacked in three stages, and each stage includes four toilet paper rolls R aligned in a square shape with the central axis in the vertical direction. Yes. Therefore, twelve toilet paper rolls R are accommodated in the packaged product P. In addition, the number and arrangement | sequence of the toilet paper roll R accommodated in the packaging bag 1 are not limited to these.

  When the tubular part of the packaging bag 1 surrounding the toilet paper roll R in the packaged product P is referred to as an enclosed part 9 and the part between the seal part 6 and the enclosed part 9 is referred to as an intermediate part 10, the intermediate part 10 is packaged. In the product P, a triangular prism-shaped space is defined above the toilet paper R.

  As shown in FIG. 1, a perforation 11 is formed in the intermediate portion 10.

  The perforation 11 is formed along a pair of reference lines 12. As shown in FIG. 4, each reference line 12 has a lateral portion 12T extending inward in the lateral direction T from the side edge of the packaging bag 1, that is, the crease line 5, and downward from an inner end 12TE of the lateral portion 12T. And an inclined portion 12S extending inward while being inclined. Here, the angle θ formed by the lateral portion 12T and the inclined portion 12S is about 8 °. In the embodiment according to the present invention, the pair of reference lines 12 are formed in a mirror image.

  The cut portion 11T of the perforation 11 along the lateral portion 12T is substantially parallel to the lateral portion 12T. On the other hand, the cut portions 11S of the perforations 11 along the inclined portions 12S intersect the inclined portions 12S alternately with a reverse inclination.

  Furthermore, in the embodiment according to the present invention, the length LS of the cut portion 11S is shorter than the length LT of the cut portion 11T.

  Moreover, the inner ends 12SE of the inclined portion 12S are separated from each other by the perforation-free region 13 where no perforation is formed.

  The cut portions 11T and 11S of the perforation 11 pass from the front surface 2 through the side surface 4 to the rear surface 3.

  The packaging bag 1 is composed of a plastic film. As the plastic, for example, linear lowden polyethylene and those blended with lowden polyethylene, polypropylene, highden polyethylene and the like can be used.

  Further, in the embodiment according to the present invention, the orientation direction of the packaging bag 1 substantially coincides with the longitudinal direction L. However, the orientation direction of the packaging bag 1 is preferably along the reference line 12.

  In use, the packaging bag 1 is broken along the perforation 11 and opened. That is, first, as shown in FIG. 5A, the seal portion 6 and the intermediate portion 10 are held by the user on one side of the packaging bag 1, and then the seal portion 6 is pulled in the direction of the arrow. As a result, the packaging bag 1 is partially broken along the perforation 11.

  Next, as shown in FIG. 5B, the seal portion 6 and the intermediate portion 10 are held by the user on the other side of the package P, and then the seal portion 6 is pulled in the direction of the arrow. As a result, the packaging bag 1 is further broken along the perforation 11.

  Next, as shown in FIG. 5C, the seal portion 6 is torn off from the intermediate portion 10. As a result, the packaging bag 1 is opened.

  In this way, a large opening can be formed in the packaging bag 1. Therefore, the toilet paper roll R can be easily taken out from the packaging bag 1.

  In this case, since the perforation 11 is formed in the packaging bag 1, the packaging bag 1 can be easily broken without using a tool such as scissors. In particular, the perforation 11 is formed along the lateral portion 12T of the reference line 12, the cut portion 11T is substantially parallel to the lateral portion 12T, and the length LT of the cut portion 11T is relatively long. The perforation 11 can be easily started to break.

  Moreover, the packaging bag 1 after being opened can maintain the shape of the bag. Therefore, the packaging bag 1 can be easily reused, for example, as a garbage bag.

  On the other hand, the perforations 11 are formed along the inclined portions 12S of the reference line 12, and the cut portions 11S of the perforations 11 along the inclined portions 12S intersect the inclined portions 12S alternately with a reverse inclination. . Further, the length LS of the cut portion 11S is relatively short, and the angle θ formed by the lateral portion 12T and the inclined portion 12S is about 8 °. Moreover, the inner ends 12SE of the inclined portion 12S are separated from each other by the perforation-free region 13. As a result, the strength reduction of the packaging bag 1 due to the formation of the perforation 11 is suppressed. That is, the packaging bag 1 is prevented from breaking along the perforation 11 when the packaged product P is carried, and therefore the toilet paper roll R as the contents is kept clean.
