=== EMBODIMENT === In the following, an example of an example of a pants-type disposable diaper for adults is exemplified for the pants-type absorbent article of the present invention. However, the pants-type absorbent article of the present invention can be used, for example, in diapers for nipples and tampon-type sanitary napkins.

<<Basic Configuration of the Disposable Diaper 1 of the Pants Type>> The first figure is a schematic perspective view of the disposable diaper 1 (hereinafter referred to as "diaper"). Fig. 2A is a plan view of the diaper 1 in a state in which the absorbent body 10 and the belt portion 20 are elongated in the longitudinal direction, and Fig. 2B is a cross-sectional view taken along line AA of Fig. 2A. Fig. 3A is a plan view of the diaper 1 in which the joint portion of Fig. 2A is separated, and Fig. 3B is a cross-sectional view taken along line AA of Fig. 3A.

In addition, the state in which the diaper 1 is stretched is a state in which the diaper 1 is stretched until the wrinkles generated in the diaper 1 are substantially not visually recognized. Specifically, the size of each member constituting the diaper 1 (for example, the sheet 41 shown in FIG. 3B) is in a state of being uniform with the size of the member alone or extending until it is close to the length thereof.

The diaper 1 is in a pants-type state as shown in Fig. 1 when worn. The diaper 1 of the pants type has a longitudinal direction, a lateral direction, and a front-rear direction which are perpendicularly intersecting each other, and is formed with a peripheral opening portion BH and a pair of foot peripheral opening portions LH. In the longitudinal direction, the side of the opening portion BH around the weir is referred to as the upper side, and the opposite side is referred to as the lower side. The front side of the user is referred to as the front side in the front-rear direction, and the back side of the user is referred to as the rear side. Further, as shown in FIG. 2B, the direction in which the members constituting the diaper 1 are stacked is referred to as the thickness direction. In the thickness direction, the side in contact with the user is referred to as the skin side, and the opposite side is referred to as the non-skin side.

The diaper 1 has an absorbent main body 10, a pair of belt portions 20, and a pair of leg gathers 30. The pair of leg gathers 30 are arranged along both sides of the absorbent body 10 in the lateral direction.

In the diaper 1 in the planar state shown in FIG. 2A, the absorbent body 10, the pair of belt portions 20, and the pair of leg gathers 30 are aligned in the longitudinal direction, and the absorbent body 10 and the first A pair of belt portions 20 are overlapped on the skin side surface of the pair of leg gathers 30, and the skin side faces of each other face each other. In the diaper 1 in the planar state, the inner end 20a of the pair of belt portions 20 in the lateral direction is opened outward, and the belt portion 20 is folded in the center in the longitudinal direction thereof, and the absorbent body 10 and the legs are folded. The pleated portion 30 is folded in half at a slight center in the longitudinal direction, and is a diaper 1 in a pants-type state (Fig. 1).

In the diaper 1 (first drawing) of the pants type, the absorbent main body 10 and the pair of leg gathers 30 are folded in the longitudinal direction of the diaper 1 in the longitudinal direction. The pair of belt portions 20 are disposed on both sides of the absorbent body 10 in the lateral direction. In detail, one end of each belt portion 20 is joined to the end portion of the absorbent body 10 and the leg gather portion 30 in the longitudinal direction in the joint portion 2 on the front side, and the other end of each belt portion 20 is The joint portion 3 on the rear side is joined to the end portions of the absorbent body 10 and the leg gathers 30 in the longitudinal direction. That is, in the diaper 1, the pair of joint portions 2, 2, 3, and 3 are respectively provided on the front side and the rear side in the front-rear direction.

In the longitudinal direction of the diaper 1, the joint portions 2 and 3 are inclined outward from the lateral opening portion BH side toward the foot peripheral opening portion LH side. The bonding method in the joint portions 2 and 3 may, for example, be a thermocompression seal, an ultrasonic seal, an adhesive, or the like, and a known joining method.

In the diaper 1 of the pants type, the belt portion 20 can be expanded and contracted in the lateral direction, and the leg gathers 30 can be expanded and contracted in the longitudinal direction, and the diaper 1 is attached around the user's ankle and around the foot. Therefore, the belt portion 20 has a plurality of elastic members 21 that expand and contract in the lateral direction in parallel in the longitudinal direction. The leg gathers 30 are formed by juxtaposing a plurality of elastic members 31 that expand and contract in the longitudinal direction in the lateral direction. Further, the elastic members 21 and 31 may be, for example, a linear elastic member such as rubber or spandex or a sheet-like elastic member such as a stretchable nonwoven fabric or a stretchable film. Further, in the belt portion 20 and the leg gather portion 30, the sheet-like elastic member 42 is disposed at the edge portion of the entire circumference of the opening portion LH around the foot.

As shown in FIG. 2B, the absorbent body 10 is laminated with a liquid-permeable top sheet 11 (for example, a breathable nonwoven fabric), an absorbent body 12, and a liquid-impermeable lining sheet from the skin side in the thickness direction. 13 (for example, a polyethylene film or the like) and an outer sheet 14 (for example, a flexible sheet such as a non-woven fabric). In the absorbent body 12, a liquid-permeable core wrap sheet (for example, tissue paper or the like) is an absorbent core that is coated with a liquid absorbing material. The absorbent core may be exemplified by a liquid absorbent fiber such as pulp fibers containing a highly absorbent copolymer.

Further, as shown in FIG. 3A, the hydrophobic sheet 15 is provided on the skin side of the top sheet 11 in each end portion of the absorbent body 10 in the longitudinal direction. By the hydrophobic sheet 15, it is possible to suppress the excretion liquid absorbed by the absorbent body 10 from being returned to the skin side, and it is difficult to give the user an uncomfortable feeling.

Further, as shown in FIG. 3B, the leg gathers 20 and the belt portion 30 are formed by the same sheet member 40. In the sheet member 40, between the two sheets 41 (for example, a soft sheet such as a nonwoven fabric), the elastic member 21 for the belt portion 20, the elastic member 31 for the leg gather portion 30, and the leg are disposed. A sheet-like elastic member 42 of the peripheral opening portion LH. Further, in the two sheets 41 and the sheet-like elastic members 42, the holes for the opening LH around the foot are hollowed out.

In the production line of the diaper 1, as shown in FIG. 3B, a pair of sheet members 40 are disposed on both sides in the lateral direction of the absorbent body 10. Further, the sheet member 40 is folded along the longitudinal direction of the absorbent body 10 and is folded back at the skin side surface side of the absorbent body 10 by the folded-back position F0 of the hole for the opening LH around the foot, and becomes the second FIG. status. Among the sheet members 40, the portion overlapping the absorbent body 10 in the thickness direction is the belt portion 20, and the portion parallel to the absorbent body 10 in the lateral direction is the leg gather portion 30. By forming the pair of joint portions 2 and 2 on the front side and the joint portions 3 and 3 on the rear side, the folded state of the sheet member 40 is fixed, and the diaper 1 in a flat state is formed (FIG. 2A) ). However, the present invention is not limited thereto, and the belt portion 20 and the leg gather portion 30 may be formed of other members.

<<Resection line 50>> Fig. 4 is a view of the diaper 1 in a pants-type state as seen from the front side. Fig. 5 is a view of the diaper 1 in a pants-type state as seen from the rear side.

In the diaper 1, as shown in FIG. 4, the pair of joint portions 2, 2 on the front side in the lateral direction, that is, the belt portion 20 is provided with "a pair of cut lines 50". Further, as shown in FIG. 5, the pair of joint portions 3, 3 on the rear side in the lateral direction, that is, the belt portion 20 is also provided with "a pair of cut lines 50". The cutting line 50 extends from the peripheral opening portion BH toward the foot peripheral opening portion LH, and has a predetermined length (La, Lb) in the longitudinal direction.

The portion of the belt portion 20 on which the cutting line 50 is disposed is weaker than the surrounding portion, and is easily torn. The cut line 50 is exemplified by a plurality of holes which are arranged at intervals. The plural hole portion refers to a portion where the sheet 41 constituting the belt portion 20 is thinned or a portion that penetrates. In the other, the cut line 50 can be exemplified by a groove type in which the sheet 41 is continuously thinned.

When the user himself takes off the diaper 1 or the caregiver removes the diaper 1 from the user, the user and the caregiver (hereinafter, the user) tear the cut line 50 to make a pair of belt portions. The 20 is unfolded in the lateral direction to spread the absorbent body 10 in the longitudinal direction thereof. Therefore, it is easy to remove the clothes as compared with the case where the diaper 1 is pulled down to remove the feet. Further, compared with the case where the joint portions 2, 3 are torn, the diaper 1 can be easily torn by a weak force, and it is easy to remove the diaper.

As shown in FIG. 4 and FIG. 5, in the diaper 1, the longitudinal end portion 10a of the absorbent main body 10 extends up to the upper end portion of the diaper 1, and forms a peripheral opening portion BH together with the belt portion 20. The belt portion 20 has the elastic member 21 that expands and contracts in the lateral direction. Therefore, the end portion 10a of the absorbent body 10 in the longitudinal direction does not expand and contract in the lateral direction.

And the user generally tears from above the cut line 50. Further, when the cut line 50 is torn, the user holds both sides of the cut line 50 so that the cut line 50 is held at the center of the portion held by each of the hands.

Here, as shown in FIG. 4 and FIG. 5, the end portion 10a of the absorbent body 10 in the longitudinal direction is placed under the natural state, that is, the diaper 1 of the pants-type state in a state in which no external force is applied. When the length in the lateral direction is set to L, the range from the joint portion 2, 3 to the position where the length L is parallel to the outer side in the lateral direction in parallel with the joint portions 2, 3 (a pair of stitches in the figure) 4) The range of the holding), the cutting line 50 can be set.

It is assumed that the cutting line 50 is provided at a position outside the lateral direction of the above-described range, that is, a position away from the end portion 10a of the longitudinal direction of the absorbent body 10. In this case, when the cutting line 50 is torn, the user can easily hold the belt portion 20 with both hands. In this case, for example, when the hand holding the portion on the one side of the cutting line 50 is fixed, and the hand holding the other side of the cutting line 50 is pulled in the lateral direction, the fixed portion is elongated in the lateral direction and is difficult to fix. Stretching is becoming unstable. Further, since both sides of the cutting line 50 in the lateral direction are elongated, the position where the user holds each of the two hands is far away from the cutting line 50. In this case, the force does not easily act on the cutting line 50, and the belt portion 20 may be torn at an unexpected position along the horizontal elastic member 21 or the like.

Therefore, the cutting line 50 may be provided within the above range. In this way, when the user takes the reticle 1 by holding the reticle 1 at the center of the portion held by the two hands, the user can easily grip the end portion 10a of the absorbent body 10 in the longitudinal direction by the hand on the side of the sheet. In other words, the user can be induced to grip the end portion 10a of the absorbent body 10 that does not expand and contract in the longitudinal direction.

In this case, the user can securely cut the cutting line 50 in the horizontal direction by the other hand in a state in which the end portion 10a in the longitudinal direction of the absorbent body 10 that does not expand and contract in the lateral direction is reliably fixed by one hand. The outer side is stably stretched, and the cut line 50 can be easily torn. When the cutting line 50 is stretched, the cutting line 50 does not move away from the end portion 10a of the absorbent body 10 held by the user in the longitudinal direction, and the force is easily applied to the cutting line 50. Therefore, even if the force is weak, the belt portion 20 can be torn beautifully and easily along the cutting line 50.

Moreover, the range of the longitudinal direction of the end portion 10a of the absorbent main body 10 in the longitudinal direction can be exemplified as the following range. For example, the upper end portion 20a of the belt portion 20 is folded back as shown in FIG. 2B, and the portion of the absorbent body 10 whose longitudinal portion is repeated in the folded portion 20a is the end portion of the absorbent body 10 in the longitudinal direction. 10a can be. In this case, in the diaper 1 of the present embodiment, the range from the upper end 10a1 of the absorbent main body 10 to the lower side of the longitudinal direction of 20 mm is the end portion 10a. In addition, the portion of the absorbent body 10 which is overlapped with the hydrophobic sheet 15 shown in FIG. 3 in the longitudinal direction may be the end portion of the absorbent body 10 in the longitudinal direction.

In the diaper 1, the joint portions 2 and 3 are inclined outward in the lateral direction toward the lower side in the longitudinal direction, and the absorbent body 10 has a shape in which the tip end is tapered toward the upper side. Therefore, among the end portions 10a in the longitudinal direction of the absorbent body 10, the length L2 of the lower end 10a2 in the lateral direction is longer than the length L1 of the upper end 10a1 in the lateral direction. Therefore, in the joint portions 2 and 3, in parallel with the joint portions 2 and 3, only the length L2 in the lateral direction of the lower end 10a2 of the end portion 10a in the longitudinal direction of the absorbent body 10 is distant from the outer side in the lateral direction. The range is provided with a cutting line 50.

More preferably, in the range from the joint portions 2 and 3 to the joint portions 2 and 3, only the length L1 in the lateral direction of the upper end 10a1 of the absorbent body 10 is distant from the outer side in the lateral direction. The line 50 can be cut off. As a result, the cutting line 50 is provided at a position closer to the end portion 10a of the absorbent body 10 in the longitudinal direction. Therefore, it is easier to induce the user to hold the end portion 10a of the absorbent body 10 in the longitudinal direction. In the diaper 1 of the present embodiment, the cut line 50 is provided at a position away from the joint portion 2, 3 toward the outer side in the lateral direction of 5 mm parallel to the joint portions 2, 3.

By tilting the joint portions 2 and 3 toward the outer side in the lateral direction in the longitudinal direction, for example, the longitudinal direction of the absorbent body 10 can be compared with the case where the joint portions 2 and 3 are straight in the longitudinal direction. The length of the end portion 10a in the lateral direction is shortened.

Further, the length L of the end portion 10a in the longitudinal direction of the absorbent body 10 in the lateral direction may be shorter than the length W of the absorbent core 12 in the lateral direction.

By shortening the length L of the end portion 10a of the absorbent body 10 in the longitudinal direction in the lateral direction, the cut line 50 can be provided at a position closer to the end portion 10a of the absorbent body 10 in the longitudinal direction. Therefore, compared with the case where the length L of the longitudinal direction end portion 10a of the absorbent body 10 in the lateral direction is equal to or longer than the length W of the absorbent core 12 in the lateral direction, it is easier to induce the user to extend the longitudinal direction of the absorbent body 10. The end 10a is held. Further, since the range in which the user's grip is induced is narrowed, the user becomes a position closer to the resection line 50. Therefore, the force is easily applied to the cut line 50, and the cut line 50 can be more easily torn.

The cutting line 50 is preferably along the joint portions 2, 3. The cutting line 50 is along the joint portions 2 and 3, and the cut line 50 is similar to the joint portions 2 and 3, and is also in the vertical direction from the side of the circumference around the opening BH toward the side of the foot opening LH. The outer side of the direction is inclined to form a straight line shape. More preferably, the cutting line 50 is parallel to the joint portions 2, 3.

As a result, the distance from the joint portions 2 and 3 which are rigidly opposed to the tensile force to the cut line 50 is constant, and a constant force is likely to act on the cut line 50. Therefore, the belt portion 20 can be torn beautifully and easily along the cutting line 50.

However, the present invention is not limited to the above, and the cut line 50 may have a predetermined length in the longitudinal direction, and any shape may be formed when the belt portion 20 is unfolded in the lateral direction by the tear of the cut line 50. For example, the cut line 50 may be a wave line shape or the like.

In the diaper 1, as shown in Fig. 2, the angle θ1 between the longitudinal center line CL of the absorptive main body 2 in the lateral direction and the joint portion 2 on the front side is larger than the longitudinal center line CL and The angle θ2 formed between the joint portions 3 on the side is larger. In this way, in the front side where the inclination of the joint portion 2 is relaxed, the belt portion 20 tends to be inclined outward in the lateral direction. On the other hand, in the rear side, the belt portion 20 tends to be inclined toward the center in the lateral direction. Therefore, in the front side, it is possible to prevent the movement of the user's foot from being hindered by the belt portion 20. On the other hand, in the rear side, the diaper 1 can be pulled up, and the user's buttocks can be covered. Further, regarding the cutting line 50, the angle formed between the front side and the rear side and the longitudinal center line CL may be different.

And as previously mentioned, the user typically tears over the resection line 50. Therefore, it is preferable that the upper end 50a of the cutting line 50 (the end on the side of the opening portion BH around the crucible) is the opening portion BH around the crucible or the upper end portion 20a of the belt portion 20 (for example, the portion where the belt portion 20 is folded back). By doing so, the cutting line 50 can be torn by a relatively weak force, and the cutting line 50 can be easily torn.

On the other hand, the lower end 50b of the cutting line 50 (the end on the side of the opening portion LH around the foot) is preferably not reached to the opening portion LH around the foot. It is assumed that if the cutting line 50 reaches the opening portion LH around the foot, the belt portion 20 is quickly and strongly torn along the cutting line 50 until the end. In this case, the belt portion 20 is deployed quickly and vigorously, and the excrement may be scattered. Further, as the tearing of the cutting line 50 advances, the position near the opening portion BH around the cymbal held by the user and the position of the tearing are distant. In this case, the force does not easily act on the cutting line 50, and the belt portion 20 may be torn at an unexpected position along the horizontal elastic member 21 or the like.

Here, by stopping the cutting line 50 in front of the opening portion LH around the foot, it is possible to suppress the force by which the cutting line 50 is torn. Therefore, it is possible to induce the user to carefully tear the belt portion 20 to tear at the end. Further, the user can be induced to re-hold the vicinity of the opening portion LH around the foot. Therefore, the tear of the belt portion 20 in an unexpected position can be prevented.

Specifically, in the vertical direction, the cutting line 50 is located at the side of the peripheral opening portion BH of the elastic member 21a on the side of the opening portion LH of the forefoot among the linear elastic members 21 of the belt portion 20. .

By doing so, the force by which the cut line 50 is torn can be suppressed by the linear elastic member 21. Therefore, at the end of the tearing, the user re-holds the vicinity of the opening LH around the foot, and can induce the tearing of the belt portion 20 with care.

In the longitudinal direction, even if the position of the cutting line 50 is longer than the sheet-like elastic member 42 along the opening portion LH around the foot, the peripheral opening portion BH side may be provided.

By doing so, the force by which the cut line 50 is torn can be suppressed by the sheet-like elastic member 42. Therefore, at the end of the tearing, the user re-holds the vicinity of the opening LH around the foot, and can induce the tearing of the belt portion 20 with care.

However, it is not limited to the above. For example, in the diaper 1 of the present embodiment, the hard joint portions 2, 3 do not contact the user's foot, that is, the joint portions 2, 3 do not reach the foot peripheral opening portion LH. Here, the length of the cut line 50 may be set to be the same as the length of the joint portions 2 and 3. Further, the cutting line 50 may reach the opening portion LH around the foot. Further, the cutting line 50 is longer than the joint portions 2, 3, and is provided in a range from the joint portions 2, 3 and their extension lines to a position away from the outer side in which the length L is parallel to the lateral direction. The line 50 can be cut off.

Further, in the diaper 1, a pair of cut lines 50 are provided on the front side and the rear side, respectively. By providing the cutting line 50 (51) on the front side, for example, when the user himself takes off the diaper 1, the starting position for easy tearing is found, and the cutting line can be easily removed without increasing the movement of the body and the wrist. 50 (51) tear. On the other hand, by providing the cutting line 50 (52) on the rear side, the portion of the belt portion 20 on the rear side is spread away from the absorbent body 10 toward the front side. Therefore, the area of the diaper 1 which is hollowed out from the lower portion of the user's strand is reduced, and the undressing of the diaper 1 becomes easy.

Further, the length Lb of the rear cut line 50 (52) in the longitudinal direction may be shorter than the length La of the front cut line 50 (51) in the longitudinal direction (Lb < La). In other words, the length from the lower end 50b of the cutting line 50 to the opening portion LH around the foot in the direction along the cutting line 50 may be longer than the front side.

This is because the belt portion 20 on the rear side is larger in the lateral direction than the belt portion 20 on the front side, only in the portion of the buttocks where the meat is large, and when the user stands or sits down. Therefore, unnecessary tearing of the belt portion 20 can be prevented by shortening the cut line 50 (52) on the rear side.

However, it is not limited to the above. The length of the front side cut line 50 (51) in the longitudinal direction and the length of the rear cut line 50 (52) in the longitudinal direction may be the same. Further, the pair of cut lines 50 may be provided only on one side in the front-rear direction. In this case, the front and rear of the diaper 1 can be judged by the presence or absence of the cut line 50. Further, the cut-off line 50 is provided only on the sheet-side joint portion 2 side of the pair of joint portions 2, 2 provided on the front side, or the cut-off line 50 is only provided in the pair of joint portions 3, 3 provided on the rear side. The side of the joint portion 3 on the sheet side may be used. In this case, the undressing of the diaper 1 is also easier than in the case where the cut-off line 50 is not provided.

6A to 6C are explanatory views of a folding method of the diaper 1. Usually, the diapers 1 are circulated in a state in which they are individually or plurally packaged together. In the diaper 1 of the present embodiment, in the packaged state, the end portion of the belt portion 20 in the lateral direction is folded back toward the inner side in the lateral direction, and the absorbent main body 10 is folded back at the folded-back position in the lateral direction.

Specifically, first, in the folded-back position F1 shown in FIG. 6A, the end portions of the belt portion 20 in the lateral direction are folded back on the inner side in the lateral direction so that the non-skin side faces face each other. As a result, as shown in FIG. 6B, the end portion of the belt portion 20 in the lateral direction is in a state of being held by the folded absorbent body 10. Then, the absorbent body 10 is folded in the longitudinal direction by the folding position F2 in the lateral direction slightly in the longitudinal direction of the diaper 1, and the diaper 1 is in the state shown in FIG. In this state, the diaper 1 is packaged. Further, although not shown, the end portion of the belt portion 20 in the lateral direction is folded back inside the lateral direction so as to be positioned on the non-skin side surface of the absorbent body 10, and the absorbent body 10 is placed at the folding position F2. Foldback is also possible.

When the diaper 1 is folded, in the package state of the diaper 1 (the state of FIG. 6C), the cut line 50 is located in the longitudinal direction than the folded-back position F2 along the lateral direction of the absorbent body 10. It is preferable that the side of the opening portion BH is around the side.

By doing so, it is possible to prevent the fold line along the lateral direction from being formed on the cut line 50 and its periphery. Therefore, it is possible to prevent the belt portion 20 from being horizontally torn along the fold line in the middle of the tear of the cut line 50, and the belt portion 20 can be torn beautifully and easily along the cut line 50.

<<Modification>> FIGS. 7A to 7C are explanatory views of a modification of the diaper 1. The diaper 1 of the modified example is provided with a hook sheet 60 across the cutting line 50 as shown in Fig. 7A. The hook sheet 60 is, for example, a sheet of a male material (hook-shaped projection) including a flat fastener (magic felt), and is a sheet that can be engaged with the non-woven fabric constituting the belt portion 20. The hook sheet 60 is provided on the non-skin side surface of the belt portion 20, and the surface provided with the protrusion faces the belt portion 20. Here, as shown in FIG. 7B, in the joint portion 3, a hook sheet 60 is fixed between the absorbent body 10 and the belt portion 20. However, the present invention is not limited thereto, and for example, the hook sheet 60 may be fixed to the belt portion 20 by an adhesive. Further, the hook sheet 60 is not directly limited to the belt portion 20, and a base material of a flat fastener (magic felt) may be provided on the non-skin side surface of the belt portion 20.

In the diaper 1 of the modification, when the user tears the cut line 50, the belt portion 20 is torn, and the hook sheet 60 is not torn. Therefore, as shown in Fig. 7C, the hook sheet 60 (the surface on which the projection is provided) is exposed. Therefore, after the tear of the cut line 50, the diaper 1 can be worn again by locking the non-skin side of the belt portion 20 to the hook sheet 60.

According to the diaper 1, after the tearing of the cutting line 50, the user confirms the excretion state, and it is judged that the diaper 1 in use can be used, and the diaper 1 can be worn again by the hook sheet 60. Further, in the case where the absorbent pad is used in the diaper 1, the absorbent pad can be easily exchanged. Moreover, by causing the hook sheet 60 to straddle the cut line 50, it is possible to suppress the cut line 50 from being unnecessarily torn. Moreover, even if the cut line 50 is unnecessarily torn, the diaper 1 can be worn by the hook sheet 60.

Further, in FIG. 7A, the lengths of the hook sheet 60 and the cut line 50 are the same, but the hook sheet 60 may be shorter or longer than the cut line 50, but is not limited thereto. By shortening the hook sheet 60, it is difficult to give the user a strange feeling. Conversely, by lengthening the hook sheet 60, the belt portion 20 can be surely fixed to the hook sheet 60 when it is worn again. Further, the diaper 1 may be provided with a plurality of cut lines 50, and the hook sheets 60 may be provided corresponding to the respective cut lines 50, and only the hook lines 60 may be provided for a part of the cut lines 50.

The embodiments of the present invention have been described above, but the above-described embodiments are not intended to limit the scope of the present invention. It is to be understood that the invention may be modified and modified without departing from the spirit and scope of the invention.
