Next, a method for manufacturing the package 1 according to the embodiment will be described.
FIG. 8 is a schematic view showing an example of a method for manufacturing a package according to an embodiment. In this manufacturing method, as an example, a manufacturing method of the gusset type package 1 will be described. However, this manufacturing method has a transport direction MD, a transverse direction CD, and a thickness direction TD (not shown) that are orthogonal to each other in the transport of materials in each step.

First, a packaging bag 2 capable of storing a plurality of absorbent articles 3 is formed. The method for forming the packaging bag 2 includes a surface forming step and a weakening line forming step.

In the side surface forming step, both sides of the transverse CD in the tubular resin sheet member 50 extending along the transport direction MD (FIG. 8A) are folded in valley folds toward the inside of the transverse CD. .. As a result, the side surface forming step is folded between the front surface portion 11 and the rear surface portion 12 located on one side and the other side of the thickness direction TD, respectively, and the front surface portion 11 and the rear surface portion 12, and is folded on the right side of the transverse direction CD. And the right side portion 13 and the left side portion 14 located on the left side, respectively (FIG. 8 (b)). At this time, the front surface portion 11 and the rear surface portion 12 overlap in the thickness direction TD, and the right side portion and the right surface portion 13 of the front surface portion 11 and the rear surface portion 12 overlap in the thickness direction TD, and the front surface portion 11 The left side portion of the rear surface portion 12 and the left surface portion 14 overlap with each other in the thickness direction TD.

In the weakening line forming step, the weakening line forming blade (not shown) is pressed from one side of the front surface portion 11 and the rear surface portion 12 toward the other side (in the thickness direction TD). For example, the folded sheet member 50 is sandwiched between a roll having a weakening line forming blade and an anvil roll. As a result, in the weakening line forming step, two vertical weakening lines 25 extending in the transport direction MD and a horizontal weakening line 24 extending in the transverse direction CD are formed on the front surface portion 11 and the rear surface portion 12. Along with this, at the same time, two vertical weakening lines 25 extending in the transport direction MD and the transverse direction are formed on the right surface portion 13 and the left surface portion 14 located between the front surface portion 11 and the rear surface portion 12 and overlapping the thickness direction TD. A lateral weakening line 24 extending to the CD is formed. At this time, the position of the lower end of the transport direction MD on the two vertical weakening lines 25 is parallel to the transport direction MD in the plurality of absorbent articles 3 when the packaging bag 2 contains the plurality of absorbent articles 3. Two vertical weakening lines 25 and horizontal weakening lines 24 are formed so as to be higher than the position of the lower end of the vertical direction T and lower than the position in the middle of the vertical direction T in the plurality of absorbent articles 3.

Further, in the weakening line forming step, another weakening line forming blade (not shown) is pressed from one side of the front surface portion 11 and the rear surface portion 12 toward the other side (in the thickness direction TD). For example, the sheet member 50 which is folded and has the horizontal weakening line 24 and the two vertical weakening lines 25 is sandwiched between a roll having another weakening line forming blade and an anvil roll. As a result, the weakening line forming step forms the first weakening line 21 and the second weakening line 22 extending along the transverse direction CD on the front surface portion 11 and the rear surface portion 12. Along with this, at the same time, the first weakening line 21 and the second weakening line 21 and the second weakening line 21 extending along the transverse direction CD are located between the front surface portion 11 and the rear surface portion 12 and overlap the right surface portion 13 and the left surface portion 14 in the thickness direction TD. The weakening line 22 is formed. At this time, the adjacent first weakening lines 21 are separated from each other at the corner portion 19, and the adjacent first weakening line 21 and the second weakening line 22 are separated from each other, and the adjacent second weakening lines 22 and the first weakening line 22 are separated from each other. The distance to the weakening line 21 is shorter than the distance between the adjacent first weakening lines 21, and the extension line of the end of the second weakening line 22 is the first weakening line adjacent to the end of the second weakening line 22. The first weakening line 21 and the second weakening line 22 may be formed so as to intersect the line 21.

However, either of the step of forming the two vertical weakening lines 25 and the horizontal weakening line 24 and the step of forming the first weakening line 21 and the second weakening line 22 may be performed first, or at the same time. You may. When performed at the same time, for example, the folded sheet member 50 is sandwiched between one roll having a weakening line forming blade and another weakening line forming blade and an anvil roll. At the same time, the handle portion 18 may be formed. As described above, the packaging bag 2 is formed (FIG. 8 (c)).

At this time, when the packaging bag 2 of FIG. 8C is cut at the boundary line CL between the rear surface portion 12 and the left surface portion 14 and unfolded, the result is as shown in FIG. Here, consider the region STA including the boundary line CL between the right surface portion 13 and the front surface portion 11. However, in the region STA, the width in the direction parallel to the bottom surface portion 16 along the surface of the packaging bag 2 (width direction W and depth direction D) is the same as the width of the right surface portion 13, and is along the surface of the packaging bag 2. The center in the direction parallel to the bottom surface portion 16 (width direction W and depth direction D) is a rectangular region which is a boundary line CL between the right surface portion 13 and the front surface portion 11. At this time, in the region STA, the second weakening line straddling the boundary line CL is axisymmetric with respect to the boundary line CL. Further, the first weakening line, the horizontal weakening line and the vertical weakening line of the front surface portion 11 adjacent to both sides of the boundary line CL and the first weakening line, the horizontal weakening line and the vertical weakening line of the right surface portion 13 are the boundary line CL. It is line symmetric with respect to. The same applies to the region STA (not shown) including the other boundary line CL. For example, in the region STA including the boundary line CL between the right surface portion 13 and the rear surface portion 12, the width thereof is the same as the width of the right surface portion 13, and the second weakening line straddling the boundary line CL, the adjacent rear surface portions 12 and the right. The first weakening line, the horizontal weakening line, and the vertical weakening line of the surface portion 13 are line-symmetrical with respect to the boundary line CL. Further, in the region STA including the boundary line CL between the left surface portion 14 and the front surface portion 11, the width thereof is the same as the width of the left surface portion 14, and the second weakening line straddling the boundary line CL, the adjacent front surface portions 11 and the left The first weakening line, the horizontal weakening line, and the vertical weakening line of the surface portion 14 are line-symmetrical with respect to the boundary line CL. Further, in the region STA including the boundary line CL between the left surface portion 14 and the rear surface portion 12, the width thereof is the same as the width of the left surface portion 14, and the second weakening line straddling the boundary line CL, the adjacent rear surface portions 12 and the left The first weakening line, the horizontal weakening line, and the vertical weakening line of the face portion 14 are line-symmetrical with respect to the boundary line CL.

After that, the bottom surface side portion of the formed packaging bag 2 is sealed by heat fusion to form the bottom surface portion 16. Next, a plurality of absorbent articles 3 are stored from the upper surface side of the packaging bag 2. Finally, the upper surface side portion of the packaging bag 2 is sealed by heat fusion to form the joint portion 17. As described above, the gusset type package 1 is formed.

In the present embodiment, as shown in FIGS. 1 to 4, the package 1 may be a gusset type. In that case, the right surface portion 13 and the left surface portion 14 are portions folded in a valley fold on the right side and the left side in the width direction W between the front surface portion 11 and the rear surface portion 12, respectively.

FIG. 9 is a front view and a right side view schematically showing another configuration example of the package 1 according to the embodiment. In this figure, the front view and the right side view of another configuration example of the package 1 are drawn adjacent to each other. In the present embodiment, at least one of the right surface portion 13 and the left surface portion 14, and at least one of the front surface portion 11 and the rear surface portion 12, the positions H2D and the positions H1D of the lower ends of the vertical weakening lines 25 on the two vertical weakening lines 25. May be the same. For example, the position H2D at the lower end of the two vertical weakening lines 25 on the right surface portion 13 and the position H1D at the lower end of the two vertical weakening lines 25 on the front surface portion 11 may be the same. Therefore, the opening portion 20 of the right surface portion 13 or the left surface portion 14, that is, the opening portion 20 that opens in the width direction W, and the opening portion 20 of the front surface portion 11 or the rear surface portion 12, that is, the opening portion 20 that opens in the depth direction D. Even if both are opened, the positions H2D and H1D at the lower ends of the opening OPB and the opening OPA can be aligned in the same manner. As a result, once the user grasps the position H2D or H1D of the lower end of either opening portion 20, even when the absorbent article 3 is taken out from any opening portion 20, the position of the lower end H2D or H1D The absorbent article 3 can be easily taken out from the side surface portion without visually confirming each time.

Further, in the present embodiment, as shown in FIG. 9, at least one of the right surface portion 13 and the left surface portion 14 and at least one of the front surface portion 11 and the rear surface portion 12 in the vertical direction on the two vertical weakening lines 25. The position H2U and the position H1U at the upper end of T may be the same. For example, the position H2U at the upper end of the two vertical weakening lines 25 on the right surface portion 13 and the position H1U at the upper end of the two vertical weakening lines 25 on the front surface portion 11 may be the same. Therefore, the opening portion 20 of the right surface portion 13 or the left surface portion 14, that is, the opening portion 20 that opens in the width direction W, and the opening portion 20 of the front surface portion 11 or the rear surface portion 12, that is, the opening portion 20 that opens in the depth direction D. Even if both are opened, the positions H2U and H1U at the upper ends of the opening OPB and the opening OPA can be aligned in the same manner. As a result, once the user has grasped the position H2U or H1U of the upper end of either opening portion 20, even when the absorbent article 3 is taken out from any opening portion 20, the position of the upper end H2U or H1U The absorbent article 3 can be easily taken out from the side surface portion without visually confirming each time.

Further, in the present embodiment, as shown in FIG. 9, the vertical weakening line 25 on the front surface 11 side of the two vertical weakening lines 25 on at least one of the right surface portion 13 and the left surface portion 14 and the right surface portion thereof. The distance d23 between at least one of 13 and the left surface portion 14 and the boundary line CL between the front surface portion 11 is the distance d23 of at least the right surface portion 13 and the left surface portion 14 of the two vertical weakening lines 25 in the front surface portion 11. The distance d13 between the vertical weakening line 25 on one side and the boundary line CL thereof may be the same. For example, the distance d23 between the vertical weakening line 25 on the front surface portion 11 side of the right surface portion 13 and the boundary line CL between the right surface portion 13 and the front surface portion 11 is the vertical weakening line 25 on the right surface portion 13 side of the front surface portion 11. , The boundary line CL and the distance d13 may be the same.
Here, the distance d23 between the vertical weakening line 25 on the front surface portion 11 side of the right surface portion 13 or the left surface portion 14 and the boundary line CL is set on both outer sides of the opening OPB of the opening portion 20 of the right surface portion 13 or the left surface portion 14. The width of the part. On the other hand, the distance d13 between the vertical weakening line 25 on the right surface portion 13 side or the left surface portion 14 side in the front surface portion 11 and the boundary line CL is the width of both outer portions of the opening OPA of the opening portion 20 in the front surface portion 11. Is. Both outer portions of the opening OPB and the opening OPA of the opening portion 20 are portions necessary for maintaining the shape of the side surface portion after opening and, by extension, maintaining the shape of the package 1. Therefore, if the widths of these portions are not well balanced, it becomes difficult to maintain the shape of the side surface portion and the package 1 after opening. Therefore, in this package 1, a predetermined same width is provided so that these widths do not differ greatly from side to side. This makes it easier to maintain the shape of the side surface portion and the package 1 after opening. As a result, the shapes of the opening OPB and the opening OPA of the opened portion are maintained, and the ease of taking out the absorbent article 3 can be maintained.
