A gather 35 (see FIG. 1) is formed by contraction of the elastic member 253 around the left leg 251.

FIG. 3 is an enlarged view of a main part of the pant-type diaper 1 of FIG. More specifically, it is the figure which expanded the tag 37 in the clothing side surface of the underpants type diaper 1. FIG.

As shown in FIG.1 and FIG.3, in this embodiment, the tag 37 is provided in the ventral | joint junction part 91 in the clothing side surface of the underpants type diaper 1. FIG. The tag 37 has a fixed portion 371 fixed to the ventral side joint portion 91 by heat fusion, and a non-fixed portion 373 extending from the fixed portion 371. The fixed portion 371 and the non-fixed portion 373 are: Paired. Moreover, in this embodiment, the tag 37 is arrange | positioned so that the edge extended in the longitudinal direction of the fixing | fixed part 371 and the width direction edge of the underpants type diaper 1 in the ventral | joint junction part 91 may correspond. , non-fixed portion 373 extends toward the lateral center axis C _L of the pants-type diaper 1.
Further, the fixed portion 371 and the non-fixed portion 373 are partitioned by a boundary line 374.
In the present embodiment, the non-fixed portion 373 refers to a portion other than the fixed portion 371 in the tag 37.

In addition, in this embodiment, although the fixing | fixed part 371 and the non-fixed part 373 have made a pair, the fixed part and non-fixed part of the tag in the absorbent article which concern on this invention have made the pair. For example, for one fixed portion, one non-fixed portion is provided at each end in one direction of the fixed portion, that is, a total of two, and the tag as a whole is shaped like a ribbon. You may have.

Thus, since the tag 37 has a pair of fixing portions 371 fixed to the ventral joint portion 91 and the non-fixing portion 373 extending from the fixing portion 371, the user uses the tag in the non-fixing portion 373. 37 can be easily grasped with a finger, and the ease of carrying the pants-type diaper 1 is increased.

Further, the non-fixed portion 373 extends toward the width direction central axis C _L (FIG. 2) of the pants-type diaper 1, and the tag 37 is outward in the width direction of the pants-type diaper 1 with the fixed portion 371 as a base point. Since it does not extend to the side, the tag does not get in the way when the wearer wears pants or a skirt on the pants-type diaper 1.

In still another embodiment, the tag fixing portion may be on the ventral side other than the ventral joint. However, in order to ensure the visibility of the tag, the tag is preferably fixed to the clothing side surface of the absorbent article.

Further, when the tag is fixed to a region overlapping with the abdominal elastic member or the leg elastic member in the thickness direction T, a gather is formed by contraction of the abdominal elastic member or the leg elastic member, and the tag is also an abdominal elastic member. Alternatively, the tag shrinks in conjunction with the leg elastic member, and the visibility of the tag deteriorates. Therefore, the tag is preferably fixed to a region other than the region overlapping with these elastic members in the thickness direction T.

FIG. 4 is a diagram showing the tag 37 in the unfolded state. More specifically, the tag 37 is comprised of a rectangular fabric is folded at the center axis C _WT in one direction of the tag 37, to form a loop. The two

opposite edges

375 and 375 are overlapped with each other so that the tag 37 is fixed to the ventral joint 91 to form a fixing portion 371, and at a portion other than the fixing portion 371, the non-fixing portion 373. Form.

In the present embodiment, the tag 37 is fixed to the ventral joint 91 by heat fusion, but the tag fixing method according to the present invention is not limited to this, and is fixed by other fixing means such as an adhesive. May be. The tag 37 may be fixed simultaneously with the formation of the joint portion between the abdomen and the back portion, or before or after the formation of the joint portion.

In this way, the tag 37 is a loop type tag, and the two

opposite edges

375 and 375 of the loop type tag are fixed to the ventral joint portion 91, which is more than a simple sheet type that is not a loop type. Since it has thickness and rigidity, it is easier to grasp the tag 37 with a finger and it is easier to visually recognize the shape because it can be easily held. Furthermore, by adjusting the size of the loop according to the purpose, the pants-type diaper 1 can be carried by putting a finger into the loop portion of the tag 37, or the loop portion can be suspended from the handle, etc. The ease of carrying and handling of the diaper 1 is increased.

Tag 37 shown in FIG. 4, in expanded state, one way to 50 mm (folded as the 25 mm), the same in the direction perpendicular consists nonwoven fabric having a length of 20 mm, the tag 37 is folded at the central axis _{C LT} The identification information “L” indicating the size of the pants-type diaper 1 is printed on one outer surface 377 that is visible from the outside after forming the loop shape and the other outer surface 379 on the opposite side. Are listed.

In this way, the tag 37 has identification information written on both the outer surface 377 on one side and the other outer surface 379 on the opposite side of the one outer surface 377, and the outer surface on either side of the tag 37. Therefore, even if the tag 37 is swung, the visibility is good, and more identification information can be described as compared with the case where only one or the other outer surface is described.

In addition, the shape, size, and material of the tag included in the absorbent article according to the present invention are not limited to those described above, and may have any shape, size, and material as long as the function as a tag can be exhibited. Also good.
However, the size of the tag provided in the absorbent article according to the present invention is preferably 5 mm or more and 60 mm or less, more preferably 10 mm or more and 50 mm or less, and further preferably 20 mm or more and 40 mm or less in both the lateral direction and the longitudinal direction. is there. The lower limit of the numerical range is from the viewpoint of the visibility of the identification information written on the tag, and the upper limit is from the viewpoint of ease of handling such as not obstructing when wearing pants or skirt on the absorbent article. It is determined.
In addition, the material of the tag provided in the absorbent article according to the present invention is used as a tag such as cotton, acrylic, polyester, nylon, rayon, etc., natural or artificial fiber fabric, knitted fabric, nonwoven fabric, resin film, etc. It is a common material.

The breaking strength between the tag 37 and the ventral joint 91 to which the tag 37 is fixed is smaller than the breaking strength between the ventral joint 91 and the back joint 93.

Thus, since the breaking strength of the tag 37 and the ventral joint 91 to which the tag 37 is fixed is smaller than the fracture strength of the ventral joint 91 and the dorsal joint 93, the ventral joint The tag 37 can be easily detached from the abdominal joint 91 without breaking the 91 and the back joint 93, and the tag 37 and the pants-type diaper 1 can be easily discarded separately.

Further, as shown in FIGS. 3 and 4, the tag 37 includes a weak portion 372 extending along a boundary line 374 between the fixed portion 371 and the non-fixed portion 373 in the non-fixed portion 373.
In the present embodiment, the fragile portion 372 is provided along the boundary line 374 and close to the boundary line 374. However, the fragile portion included in the tag in the absorbent article according to the present invention is the tag. As long as the area where the identification information is described and the area where the identification information is not described are partitioned, the area may be provided at an arbitrary position.
FIG. 9 is a view showing a state after the tag 37 of the pants-type diaper 1 is broken at the fragile portion 372.

As described above, the tag includes the fragile portion 372 extending along the boundary line 374 between the fixed portion 371 and the non-fixed portion 373 in the non-fixed portion 373, and the tag is broken at the fragile portion 372 to form a pants-type diaper. Since it can be easily removed from 1, the tag 37 and the pants-type diaper 1 can be easily discarded separately.

This is particularly effective when the identification information written on the tag is the name of the wearer of the absorbent article included in the field for writing the name of the wearer, as will be described in another embodiment described later. is there. For example, in a kindergarten, a nursery school, etc., it may be necessary to submit the name of the kindergarten in a spare diaper that the kindergarten will use on that day. In such a case, with the above configuration, the tag on which important personal information such as the name of the wearer is described is easily removed from the absorbent article after use, and the tag and the absorbent article can be easily disposed of separately. Therefore, the sense of security for the user of the absorbent article is increased.
The weak part in this absorbent article can be formed with perforations, for example. Moreover, it changes to a weak part and you may make a notch in a tag and make an absorbent article easy to tear by the notch.

Here, the magnitude of the breaking strength is evaluated as follows.
(1) The absorbent article with the tag fixed to the ventral joint or the back joint is cut out in the plane direction so that the tag, the ventral part, and the back part have the same shape and size. It includes an edge in the direction in which the fixing portion extends (that is, the direction in which the ventral joint portion and the dorsal joint portion extend), and the non-fixing portion of the tag is in the pulling direction (that is, the fixing portion extends). The size is 25 mm in the direction perpendicular to the direction to be stretched) and 20 mm in the direction perpendicular to the pulling direction (that is, the direction in which the fixing portion extends).
However, in this evaluation, a sample of an absorbent article in which a fragile part is not provided in the tag is used.
In addition, although the sample of this test was 20 mm in the direction orthogonal to the pulling direction, it can be adjusted as appropriate as long as a later-described chuck can be reliably set.
(2) The tag and the one where the tag is not fixed (hereinafter, referred to as member A) among the ventral part or the dorsal part is provided to a Tensilon testing machine.
(3) A tag is attached to one chuck and a member A is attached to the other chuck in the Tensilon tester, and the chuck width is adjusted so that the joint between the ventral portion and the dorsal portion is located in the center. Is set to 30 mm.
(4) A tensile test is performed at a tensile speed of 30 m / min to observe where the fracture occurs in the sample.
(5) (i) Of the ventral part or the dorsal part, if there is a break between the tag (hereinafter referred to as member B) and the tag, The breaking strength is evaluated to be smaller than the breaking strength between the member A and the member B.
(Ii) If a break occurs between the member A and the member B, it is evaluated that the break strength between the tag and the member B is larger than the break strength between the member A and the member B.
