Therefore, even if the package 1 is placed anywhere, the absorbent article 3 can be easily taken out from the opening OPA or the opening OPB in either direction.

Further, in the present embodiment, as shown in FIGS. 1 to 4, the opening portion 20 is an upper surface portion (including the upper end 3TE1) in the vertical direction T of the plurality of absorbent articles 3 accommodated in the packaging bag 2. You may have the part 20U which covers a part of. In that case, the lateral weakening line 24 of the opening portion 20 is formed in that portion 20U. Therefore, when the unsealable portion 20 is unsealed from the lateral weakening line 24, the opening OPA and/or the opening OPA and/or An opening OPB can be formed.

In that case, the position H1D and/or position H2D of the lower end of the vertical direction T on the two longitudinal weakening lines 25 is the position of the lower end of the vertical direction T of the uppermost absorbent article 3 among the plurality of absorbent articles 3. It is higher than HAD and lower than the middle position HAM in the vertical direction T in the uppermost absorbent article 3 . Therefore, the uppermost absorbent article 3 among the plurality of absorbent articles 3 may fall outside from the opening OPA and/or the opening OPB, or may fall into the opening OPA and/or the opening OPB when taken out. You can prevent getting caught. Furthermore, even if a plurality of absorbent articles 3 are stacked in at least two layers, the absorbent article 3 can be taken out in order from the upper layer, so that part or all of the absorbent article 3 is covered by the opening OPA and/or the opening. The absorbent article 3 can be easily taken out without spilling out from the OPB. In addition, since the unused absorbent article 3 in the lower stage is covered with the packaging bag 2 until it is taken out, its cleanliness can be maintained. Thus, in this package 1, it is possible to prevent the absorbent article 3 from coming off from the opening OPA and/or the opening OPB, and to remove the absorbent article 3 from the opening OPA and/or the opening OPB. , and the absorbent article 3 on the lower side can be kept clean.

That is, the relationship between L1 and L0 is 0.3<L1/L0<0.8. Therefore, the length of the opening OPA and/or the opening OPB of the opening portion 20 is 30% to 80% of the length of the side portion, and the length of the portion other than the opening OPA and/or the opening OPB of the side portion is 70 to 20% of the length of the side portion. By setting the length of the opening OPA and/or the opening OPB of the unsealable portion 20 to 30% or more, the frontage of the opening OPA and/or the opening OPB is widened. The absorbent article 3 can be taken out more easily. Furthermore, by setting the length of the opening OPA and/or the opening OPB of the opening portion 20 to 80% or less, the length of the portion other than the opening OPA and/or the opening OPB of the side portion is set to more than 20%.

FIG. 7 is a schematic diagram showing a configuration example of vertical weakening lines and horizontal weakening lines according to the embodiment. In this embodiment, the lateral weakening line 24 may include a central lateral weakening line 24m located in the center and end lateral weakening lines 24e located on both sides of the central lateral weakening line 24m. In that case, the central lateral weakening line 24m is composed of a plurality of intermittently arranged central lateral weakening portions 24mw and a plurality of central non-lateral weakening portions 24mv positioned between adjacent central lateral weakening portions 24mw. . In addition, the end laterally weakened line 24e is composed of a plurality of intermittently arranged end laterally weakened portions 24ew and a plurality of end non-laterally weakened portions 24ev positioned between the adjacent end laterally weakened portions 24ew. It is Furthermore, the longitudinal weakening line 25 is composed of a plurality of intermittently arranged longitudinal weakening portions and a plurality of non-vertically weakening portions positioned between adjacent longitudinal weakening portions (reference numerals omitted). Here, let LP1 be the pitch of the central lateral weakening line 24m, and LW1 and LV1 be the lengths of the central lateral weakening portion 24mw and the central non-lateral weakening portion 24mv, respectively. Also, let LP2 be the pitch of the end laterally weakened lines 24e, and LW2 and LV2 be the lengths of the end laterally weakened portion 24ew and the end non-laterally weakened portion 24ev, respectively. The pitch of the longitudinal weakening lines 25 is the same as the pitch of the end lateral weakening lines 24e, and the lengths of the longitudinal weakening portion and the non-vertical weakening portion are equal to the lengths of the lateral end weakening portion 24ew and the non-lateral end weakening portion 24ev. be equal to the length of

That is, LV1<LV2 may be satisfied. Therefore, when opening the opening portion 20, it is possible to easily insert a finger into the central lateral weakening line 24m of the lateral weakening line 24.例文帳に追加Thereby, the cutting of the horizontal weakening line 24 can be easily started, and further, following the cutting of the horizontal weakening line 24, each of the two vertical weakening lines 25 can be easily cut off. Therefore, the opening OPA and/or the opening OPB of the opening portion 20 can be easily formed, and the absorbent article 3 can be more easily taken out from the opening OPA and/or the opening OPB. Furthermore, LW1<LW2 may be satisfied, and LP1<LP2 may be satisfied. Thereby, the entire horizontal weakening line 24 can be easily cut off, and further, following the cutting of the horizontal weakening line 24, each of the two vertical weakening lines 25 can be easily cut off. Also, the distance between the weakened portions forming each of the two vertical weakening lines 25 may be longer than the distance between the weakening portions forming the horizontal weakening lines 24 .

Next, a method for manufacturing the package 1 according to the embodiment will be described.
FIG. 8 is a schematic diagram showing an example of a method for manufacturing a package according to the embodiment. In this manufacturing method, as an example, a method for manufacturing a 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 accommodating a plurality of absorbent articles 3 is formed. The method of forming the packaging bag 2 includes a surface forming step and a weakening line forming step.

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

In the weakening line forming step, a 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 weakening line forming blades and an anvil roll. Thereby, in the weakening line forming step, two longitudinal weakening lines 25 extending in the transport direction MD and a lateral weakening line 24 extending in the transverse direction CD are formed in 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 conveying direction MD and two longitudinal weakening lines 25 extending in the transport direction MD and transverse direction A transverse line of weakness 24 is formed extending in the CD. At this time, when the plurality of absorbent articles 3 are accommodated in the packaging bag 2, the positions of the lower ends of the two longitudinal weakening lines 25 in the conveying direction MD are parallel to the conveying direction MD of 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 in the vertical direction T and lower than the middle position of the plurality of absorbent articles 3 in the vertical direction T.

Furthermore, 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 that is folded and has the horizontal weakening line 24 and two vertical weakening lines 25 formed thereon is sandwiched between another roll having a weakening line forming blade and an anvil roll. Thereby, the weakening line forming step forms the first weakening line 21 and the second weakening line 22 extending along the transverse direction CD in the front surface portion 11 and the rear surface portion 12 . Along with this, at the same time, a first weakening line 21 and a second weakening line 21 extending along the transverse direction CD are provided 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 in the thickness direction TD. A line of weakness 22 is formed. At this time, adjacent first weakening lines 21 are separated from each other at corners 19, adjacent first weakening lines 21 and second weakening lines 22 are separated from each other, and adjacent second weakening lines 22 and first weakening lines 22 are separated from each other. The distance from the weakening line 21 is shorter than the distance between adjacent first weakening lines 21, and the extension line of the end of the second weakening line 22 is the first weakening adjacent to the end of the second weakening line 22 A first line of weakness 21 and a second line of weakness 22 may be formed to intersect the line 21 .

However, the step of forming the two vertical weakening lines 25 and the horizontal weakening lines 24 and the step of forming the first weakening lines 21 and the second weakening lines 22 may be performed first, or may be performed simultaneously. may When performing them simultaneously, 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 in FIG. 8(c) is cut along the boundary line CL between the rear surface portion 12 and the left surface portion 14 and unfolded, it becomes as shown in FIG. Here, consider the area STA including the boundary line CL between the right surface portion 13 and the front surface portion 11 . However, in the area STA, the width in the direction (width direction W and depth direction D) parallel to the bottom surface portion 16 along the surface of the packaging bag 2 is the same as the width of the right surface portion 13, and is along the surface of the packaging bag 2. A rectangular area whose center in the direction (width direction W and depth direction D) parallel to the bottom surface portion 16 is the boundary line CL between the right surface portion 13 and the front surface portion 11 . At this time, in the area STA, the second line of weakness crossing the boundary line CL is line-symmetrical with respect to the boundary line CL. Furthermore, the first weakening line, the horizontal weakening line and the vertical weakening line of the front surface portion 11 and the first weakening line, the horizontal weakening line and the vertical weakening line of the right surface portion 13 adjacent to both sides of the boundary line CL are the boundary line CL is axisymmetric with respect to The same applies to areas STA (not shown) including other boundary lines CL. For example, in the area 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 crossing the boundary line CL, the adjacent rear surface portion 12 and the right The first weakening line, the horizontal weakening line, and the vertical weakening line of the face portion 13 are symmetrical with respect to the boundary line CL. Further, in the area 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 crossing the boundary line CL, the adjacent front surface portion 11 and the left The first weakening line, the horizontal weakening line, and the vertical weakening line of the face portion 14 are symmetrical with respect to the boundary line CL. Further, in the area 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 crossing the boundary line CL, the adjacent rear surface portion 12 and the left The first weakening line, the horizontal weakening line, and the vertical weakening line of the face portion 14 are symmetrical with respect to the boundary line CL.

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

In this embodiment, as shown in FIGS. 1 to 4, the package 1 may be of the gusset type. In this case, the right surface portion 13 and the left surface portion 14 are portions folded to the right and left sides 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, a front view and a right side view of another configuration example of the package 1 are drawn side by side. In the present embodiment, in 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 H1D of the lower ends of the two vertical weakening lines 25 in the vertical direction T are positioned H1D. may be the same. For example, the position H2D of the lower ends of the two vertical weakening lines 25 on the right surface portion 13 and the position H1D of the lower ends of the two vertical weakening lines 25 on the front surface portion 11 may be the same. Therefore, the unsealable portion 20 of the right surface portion 13 or the left surface portion 14, that is, the unsealable portion 20 that opens in the width direction W, the unsealable portion 20 of the front surface portion 11 or the rear surface portion 12, that is, the unsealable portion 20 that opens in the depth direction D, are opened, the positions H2D and H1D of the lower ends of the opening OPB and the opening OPA can be aligned. Accordingly, once the user grasps the position H2D or H1D of the lower end of either one of the opening portions 20, the position of the lower end H2D or H1D is the position H2D or H1D of the lower end regardless of which opening portion 20 to take out the absorbent article 3 from. The absorbent article 3 can be easily taken out from the side part without visually confirming each time.

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

Further, in the present embodiment, as shown in FIG. 9, of the two vertical weakening lines 25 on at least one of the right surface portion 13 and the left surface portion 14, the vertical weakening line 25 on the front surface portion 11 side and the right surface portion 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 and the front surface portion 11 is the distance between 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 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. , and the boundary line CL thereof may be the same as the distance d13.
Here, the distance d23 between the longitudinal weakening line 25 on the front portion 11 side of the right surface portion 13 or left surface portion 14 and the boundary line CL is the distance d23 on both sides of the opening OPB of the opening portion 20 on the right surface portion 13 or left surface portion 14. is the width of the part of 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 of the front surface portion 11 and the boundary line CL is the width of the portions on both sides of the opening OPA of the unsealable portion 20 on the front surface portion 11. is. The portions on both sides of the opening OPB and the opening OPA of the unsealing portion 20 are necessary for maintaining the shape of the side surface after unsealing, 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 portions and the package 1 after opening. Therefore, in this package 1, the same predetermined width is provided so that the widths of the side portions do not vary greatly. This makes it easy to maintain the shape of the side portion and package 1 after opening. Thereby, the shape of the opening OPB and the opening OPA of the unsealable portion is maintained, and the ease of taking out the absorbent article 3 can be maintained.

Further, for the same reason, of the two vertical weakening lines 25 on at least one of the right surface portion 13 and the left surface portion 14, the vertical weakening line 25 on the rear surface portion 12 side, and at least the right surface portion 13 and the left surface portion 14 The distance between the boundary line CL between one side and the rear surface portion 12 is the vertical weakening line 25 on at least one side of the right surface portion 13 and the left surface portion 14 of the two vertical weakening lines 25 in the rear surface portion 12. may be the same as the distance d13 between , and the boundary line CL. For example, the distance d23 between the vertical weakening line 25 on the rear surface portion 12 side of the right surface portion 13 and the boundary line CL between the right surface portion 13 and the rear surface portion 12 is equal to the vertical weakening line 25 on the right surface portion 13 side of the rear surface portion 12. , and its boundary line CL may be the same.

The packaging body 1 of the present invention is not limited to the above-described embodiments, and can be applied by adding or replacing other technologies within the scope of the purpose and spirit of the present invention as long as there is no technical contradiction. is possible.
