Description

Absorbent articles

The present invention relates to an absorbent article.

DESCRIPTION OF RELATED ART Conventionally, a tape-type disposable diaper is known as an example of an absorbent article. The diaper has a longitudinal direction, a lateral direction and a thickness direction orthogonal to each other. Moreover, the same diaper has a 1st waist part, a crotch, and a 2nd waist part in a line in the longitudinal direction. Then, each fastening tape provided at each lateral end of the second waist portion is locked to the target region of the first waist portion, whereby a waist opening and a pair of leg openings are formed. To be worn by the target person.

Moreover, the absorbent pad is known as another example of an absorbent article (patent document 1). This absorbent pad is, broadly speaking, the structure of the above-mentioned tape-type disposable diaper which does not have a fastening tape of at least the second waist part. And since it does not have a fastening tape, it is often used in combination with a diaper, but in some cases it may be used alone.

However, according to the same pad, the fastening tape does not protrude laterally outward from the second waist portion, regardless of whether it is used in combination with the diaper or alone. The insertability is excellent, so that the pad can be quickly disposed at a desired placement target position such as the inside of the disposable diaper.

On the other hand, there are low weight children who give birth at low weight of 3000 grams or less. And, such low-weight children may spend most of their time in a fetus-like bending posture when they were in the mother after birth. This fetal-like bending posture is also referred to as a positioning posture, and in this posture, the back is rounded in a C-shape in a side view as shown in FIG. 1A, and its legs are M as shown in FIG. 1B. It is in a state of being pulled so that both knees get in contact with the abdomen while opening the character. Then, after taking appropriate safety measures such as lying on a circle seat (not shown) and the like, it is in a lying posture, and most of the time is spent in a lying posture.

In addition, depending on the low weight child 101, in view of not giving extra stress, the concept of minimum handling may be applied where it is desirable not to touch the body. And tape type disposable diaper 1 'is used also for such a low weight child 101. However, from the viewpoint of minimum handling, the absorbent pad 1 p ′ (FIG. 1C) may be used alone.
For example, as shown in FIG. 1C, it is possible to perform pad replacement only by inserting and removing the absorbent pad 1p ′ from the low-weight child 101, so a disposable diaper 1 ′ requiring locking operation of the fastening tape 11 ′. Compared to the above, the absorbent pad 1p 'is used alone in the acute phase where minimum handling is particularly required, in terms of minimum handling.

However, from the viewpoint of leakproofness, the disposable diaper 1 'is more effective, and hence the use of the absorbent pad 1p' is limited to a very short period of several days in the acute phase. And as a result, the usage-amount of the same pad 1p 'is the fact that it is small compared with disposable diaper 1'.

On the other hand, in medical institutions such as NICU (neonatal intensive care unit), disposable diapers 1 'and absorbent pads 1p' are separately purchased and stored for each low-weight child 101 from the viewpoint of hygiene management and the like. That is, it is not common practice to divide and use, for example, 10 diapers 1 ′ and pads 1p ′ contained in one pack by a plurality of low-weight children 101, for example, all pads 1p ′ in one pack are one person It is prepared for low weight children 101 of the

However, as described above, since the usage amount of the absorbent pad 1p ′ is smaller than that of the disposable diaper 1 ′, if one pack of the pad 1p ′ is prepared for each low-weight child 101, the pad 1p 'I will use up, I will be discarded about the excess pad 1 p'. And this can contribute to the increase in medical expenses.

Here, if there is an absorbent article that can be used as both the disposable diaper 1 'and the absorbent pad 1p' in this respect, it is possible to solve the above-mentioned problems, and from this, at least the NICU It has been desired to provide various absorbent articles.

The present invention has been made in view of the conventional problems as described above, and its object is to provide an absorbent article that can be used as both a tape-type disposable diaper and an absorbent pad.

The main invention to achieve the above object is

At least the following matters will be made clear by the present specification and the description of the accompanying drawings.
A longitudinal direction, a transverse direction, and a thickness direction orthogonal to one another are provided, and a first waist portion, a crotch and a second waist portion are arranged in the longitudinal direction, and the transverse direction in the second waist portion is By fastening each fastening tape fixed to each end to the first waist portion, one waist opening and a pair of leg openings are formed, and a tape-type disposable diaper is obtained. A useable absorbent article,
In the unfolded state of the absorbent article, a cutting line for cutting out a protruding portion which protrudes to the outside in the lateral direction with respect to the second waist portion of at least the fastening tape is formed,
It is an absorbent article characterized by being usable as an absorptive pad which does not have the projection by cutting the projection by the cutting line.

According to such an absorbent article, if used as it is, it can be used as a tape type disposable diaper. Moreover, if the said protrusion part of a fastening tape is cut off with a tearing line, it can be used also as an absorptive pad which does not have the said protrusion part.

Such an absorbent article,
The cut lines are respectively formed at respective positions on both sides in the lateral direction, corresponding to the fastening tape,
It is preferable that the cut line is formed to cut out a portion of the second waist portion to which the fastening tape is fixed.

According to such an absorbent article, when the same absorbent article is used as a tape-type disposable diaper, the person to be worn in the lying posture is not turned over, and the person to be worn from the lying person in the lying posture is not The absorbent article can be removed. The details are as follows. First, in the general wearing form when the same article is used as a tape-type disposable diaper, the same second waist part to which the fastening tape is fixed is placed on the back side of the person to be worn. Is worn by the subject. Therefore, in the lying position, usually, the second waist part is located above in the vertical direction, but here, the above-mentioned tearing line is formed in the second waist part, and thereby the fastening The portion where the tape is fixed can be cut off quickly. Therefore, the fastening tape can be removed from the lateral center of the second waist portion in the lying posture, and as a result, the absorbent article can be developed in the same posture. And thereby, an absorptive article can be removed quickly from a person wearing a posture of a reclining posture. By the way, removing the absorbent article in the lying posture like this is suitable for the idea of minimum handling.

Such an absorbent article,
Preferably, the maximum value of the lateral spacing between the perforations is less than the maximum value of the lateral dimension of the first waist portion.

According to such an absorbent article, the maximum value of the lateral dimension of the remaining portion remaining on the second waist after being cut off at the cutting line is made smaller than the maximum value of the lateral dimension of the first waist. be able to. And if it is this way, the above-mentioned cutting out than the maximum value of the transverse dimension of both the 1st waist part and the 2nd waist part in the composition which only removed fastening tape from the absorbent article. In the case of a configuration in which only the fastening tape is removed from the absorbent article, the maximum value of the lateral dimension of the remaining part of the second waist part after being cut off with a line can be reduced. Rather, it is possible to enhance the insertability when inserting the second waist portion side as the head. Therefore, the absorbent article can be more suitably used as an absorbent pad.
In addition, by looking at the absorbent pad having the above-described size relationship, it can also be immediately recognized that the leading side at the time of insertion is the second waist part.

Such an absorbent article,
The cut line extends from the portion to be the waist opening to the inside of the second waist portion with respect to the portion of the second waist portion to which the fastening tape is fixed, and the portion around the leg It is desirable to form by the route extended to the part used as an opening.

According to such an absorbent article, it is possible to start cutting the portion of the second waist portion to which the fastening tape is fixed, from the portion serving as the waist opening or the portion serving as the leg opening. Therefore, the part to which the said fastening tape is fixed can be rapidly cut out from the absorbent article with which the wearing subject was mounted | worn as a tape type disposable diaper with a lying posture. And thereby, a fastening tape can be removed from the center part of the horizontal direction in a 2nd waist part with a lying posture, and as a result, an absorptive article can be developed with the same posture. And thereby, an absorptive article can be removed quickly from a person wearing a posture of a reclining posture.
Also, the tearing line passes through a position laterally inward of the portion of the second waist portion where the fastening tape is fixed. Therefore, when cutting the same portion, it is not necessary to cut the fastening tape. And thereby, the force required for the cutting of a tearing line can be made small, As a result, the external load which can be given to a wear subject at the time of cutting of a tearing line can be reduced.

Such an absorbent article,
The cut line is located on the inner side in the longitudinal direction while being located on the inner side in the longitudinal direction from the linear portion extending along the longitudinal direction from the portion to be the waist opening and the linear portion. It is desirable to have a curved portion with a curved shape displaced outward in the lateral direction as it proceeds.

According to such an absorbent article, the remaining portion remaining on the second waist portion after being cut off at the cutting line has the narrow portion with a small lateral dimension at the longitudinal outer position, and this narrow portion A wider portion having a larger lateral dimension than that of the above-described narrow portion will be provided longitudinally inside. Therefore, when inserting the absorbent pad with the second waist portion side as the head, since the narrow portion with a small lateral dimension is inserted as the head, the pad can exhibit good pluggability.

Such an absorbent article,
The cut line has a plurality of through holes penetrating in the thickness direction,
Preferably, the plurality of through holes are aligned along the direction in which the cut line should extend.

According to such an absorbent article, since the tearing line has the plurality of through holes, it can be easily and reliably cut in the direction in which the tearing line extends.

Such an absorbent article,
The cut line is a first cut line portion extending inward in the longitudinal direction from the portion to be the waist opening.
And a second tearing line portion located at the inner side in the longitudinal direction than the first tearing line portion and at the same position as the fastening tape in the longitudinal direction;
When the ratio of the length of the through hole in the unit length in the direction in which the cutting line extends is compared, the ratio of the second cutting line portion is more than the ratio of the first cutting line portion It is desirable to be small.

According to such an absorbent article, the first cutting line portion is easier to cut than the second cutting line portion. Therefore, it is possible to effectively prevent the second tearing line portion from being unexpectedly cut when pulling each fastening tape outward in the lateral direction so that the absorbent article is attached to the wearing target person as a tape-type disposable diaper. However, when cutting the tearing line to use the same absorbent article as an absorbent pad, it is possible to easily start cutting from the portion that becomes the waistline opening based on the first tearing line portion.

Such an absorbent article,
The cut line has a curved portion at an inner position in the longitudinal direction with respect to the second cut line portion, with a curved shape having a curved shape displaced outward in the lateral direction as advancing in the longitudinal direction,
When the ratio of the length of the through hole in the unit length in the direction in which the cutting line extends is compared, the ratio of the second cutting line portion is smaller than the ratio of the curved portion Is desirable.

According to such an absorbent article, the curved portion is easier to cut than the second tear line portion. Therefore, when pulling the respective fastening tapes outward in the lateral direction so as to attach the absorbent article as a tape-type disposable diaper to the person to be worn, it is effectively prevented that the second tearing line portion is accidentally cut. While being able to cut the cut line to use the same absorbent article as an absorbent pad, it is possible to cut the curvilinear part precisely along its curved target shape.

Such an absorbent article,
An elastic member for contracting at least the second waist portion and the crotch portion in the longitudinal direction is provided along the vertical direction, and the elasticity is provided over a predetermined range in the vertical direction in the second waist portion. A member is arranged side by side next to the transverse direction of the tear line,
In at least a part of the predetermined range, it is preferable that the elastic member be located inside the lateral direction with respect to the cutting line.

According to such an absorbent article, even in the case where the absorbent article is used as an absorbent pad, the elastic member remains in at least a part of the predetermined range in the remaining part of the second waist part. ing. Therefore, the remaining part of the second waist part can rise to the skin side in the thickness direction by the contraction force of the elastic member. Therefore, when the absorbent pad is disposed such that the remaining part of the second waist part is located on the ventral side of the person to be worn in the lying position and the first waist part is located on the back side, the second waist around the skin The rest of the part can abut the abdomen of the person to be worn. And thereby, while making the clearance gap between the abdomen of the person to be worn and the remaining part of the second waist part small, the excrement can be reliably received by the remaining part of the second waist part, and as a result, absorption The sex pad can be highly leakproof.

Such an absorbent article,
It is preferable that the elastic member is a leg elastic member for contracting the portions to be the leg openings respectively located on both sides in the lateral direction in the longitudinal direction.

According to such an absorbent article, the elastic members are respectively provided at respective positions on both sides in the lateral direction. Therefore, the remaining part of the second waist part can be stably raised so that the rising amounts on both sides in the lateral direction are substantially equalized.

Such an absorbent article,
A sheet-like solid gather forming portion provided along the longitudinal direction is provided at each position on both sides in the lateral direction,
The solid gather forming portion has a base end portion which can not stand in the thickness direction, and a standing portion which can stand on the skin side in the thickness direction with the base end portion as a fulcrum. The rising portion is contracted in the vertical direction based on the contraction force in the vertical direction acting on the rising portion, whereby the rising portion is erected on the skin side in the thickness direction,
It is preferable that the cut line is formed at a position outside the lateral direction with respect to the proximal end portion and the rising portion.

According to such an absorbent article, the tearing line is formed at a position laterally outside the proximal end portion and the rising portion of the solid gather forming portion. Therefore, even if it is in the absorptive pad which is an absorptive article after being cut off with a tearing line, the above-mentioned base end and standing part are maintained in a healthy state, that is, the base end and standing part The excrement that is held inside in the lateral direction can be properly blocked. And thereby, also when using it as an absorptive pad, the said base end part and standing part can show leakproofness substantially equivalent to the case where it uses as a tape type disposable diaper.

Such an absorbent article,
At each end in the vertical direction in the rising portion, a fixing portion is formed to fix the end in a state of being laid down on a sheet positioned on the non-skin side in the thickness direction,
It is desirable that the cut line is formed at a position outside the fixing portion in the lateral direction.

According to such an absorbent article, the fixing portion can be left on the absorbent pad which is the absorbent article after being cut off at the tearing line. Therefore, the absorbent pad can be curved so that the non-skin side in the thickness direction is on the inner peripheral side by the contraction force acting on the rising portion being input to the fixed portion, thereby wearing the absorbent pad It becomes possible to adhere closely to the subject's curved body quickly. And this contributes to the leakproof improvement of an absorptive pad.

Such an absorbent article,
It is desirable that the correspondence relationship between the ventral side and the dorsal side of the person to be worn and the first waist part and the second waist part be opposite to each other between the tape-type disposable diaper and the absorbent pad.

According to such an absorbent article, the above-mentioned correspondences are mutually opposite between the tape type disposable diaper and the absorbent pad. Therefore, the worker who wears the same article on the person to be worn performs the mounting work while being aware of one and the other in the vertical direction, so it is difficult to make a mistake in the vertical direction.

Such an absorbent article,
It is desirable to have a separate tear line for cutting off the lateral end of the first waist portion.

According to such an absorbent article, the lateral dimension of the remaining left in the lateral center of the first waist portion after being cut at the cutting line is smaller than the lateral dimension of the first waist portion before being cut. . Therefore, the insertability at the time of inserting an absorptive article can be made good at the head of the remainder of the 1st waist part after it cuts it temporarily.

FIG. 2: is a schematic plan view of the unfolded state of the absorbent article 1 of this embodiment. 3A, 3B, and 3C are a cross-sectional view taken along the line AA in FIG. 2, a cross-sectional view taken along the line BB, and a cross-sectional view taken along the line CC, respectively. Furthermore, FIG. 4 is a schematic perspective view of the absorbent article 1 in a mounted state as the tape disposable diaper 1.

This absorbent article 1 is a tape-type disposable diaper 1 attached to a person to be worn 101 using a fastening tape 11, and is suitably used particularly for low-weight children 101 having a weight of 3000 g or less. Although the subject to be worn is described below as a low-weight child 101, the subject is not limited to this, and the subject to be worn may be an infant, an infant or an adult.

In the unfolded state of FIG. 2, the absorbent article 1 has a longitudinal direction, a lateral direction, and a thickness direction as three directions orthogonal to each other. Here, in the longitudinal direction, the first waist portion 1a, the crotch 1m, and the second waist portion 1b are arranged in this order. When the article 1 is used as the tape-type disposable diaper 1 as shown in FIG. 4, generally, the first waist portion 1 a covers the ventral side of the low-weight child 101, and the crotch 1 m is the same child. The second waist portion 1b covers the back of the baby 101. However, in some cases, the absorbent article 1 may be attached to the low-weight child 101 in the opposite direction to the above. That is, the same absorbent article 1 may be worn so that the first waist part 1a covers the back side of the low-weight baby 101 and the second waist part 1b covers the belly side.

Further, in the unfolded state of FIG. 2, the first waist portion 1 a and the second waist portion 1 b respectively protrude to both sides in the lateral direction than the crotch 1 m, whereby absorption viewed from the thickness direction The outer shape of the elastic article 1 is in the form of an hourglass in plan view. In other words, the absorbent article 1 has the absorbent body 3 for absorbing the excrement fluid, and a soft and thin sheet-like portion that protrudes outward in the lateral and longitudinal directions with respect to the absorbent body 3. The external shape of the sheet-like portion is substantially sandglass-shaped in plan view.

Below, the thing of each part 1sf which protruded to the both sides of the transverse direction rather than the absorber 3 among this sheet-like parts is called "side flap 1sf." Further, the side flap 1 sf extends across three members of the first waist portion 1a, the crotch 1m and the second waist portion 1b, and in the following, the side located in the first waist portion 1a The flap 1asf is also referred to as "first side flap 1asf", and the side flap 1msf located in the crotch 1m is referred to as "crotch side flap 1msf", and the side flap 1bsf located in the second waist portion 1b Is also referred to as "second side flap 1 bsf". The second side flaps 1bsf and 1bsf correspond to "lateral end portions" according to the claims. Also, in the following, one side in the thickness direction is also referred to as the "skin side", and the other side is also referred to as the "non-skin side". Incidentally, the schematic plan view of FIG. 2 is a view of the absorbent article 1 in the unfolded state from the skin side.

Here, as shown in FIG. 2, fastening tapes 11 are provided so as to protrude in the lateral direction at the lateral outer end portions 1bsef2 of the second side flaps 1bsf, respectively. Then, by fastening each fastening tape 11 to the target area 1 at (FIG. 2) provided on the non-skin side of the first waist portion 1a, as shown in FIG. 4, the waist edge 1HB and the pair of legs The openings 1HL and 1HL are formed, whereby the absorbent article 1 is attached to the low-weight child 101.

The absorbent article 1 covers the absorbent body 3 having a substantially longitudinal shape for absorbing excrement fluid such as urine, a liquid-permeable top sheet 2 covering the absorbent body 3 from the skin side, and the absorbent body 3 from the non-skin side. A liquid-impervious leak-proof sheet 4 and a substantially hourglass-shaped exterior sheet 5 covering the leak-proof sheet 4 from the non-skin side and forming the outer shape of the absorbent article 1 And a pair of solid gather sheets 6, 6 forming solid gathers 6g, 6g as leak-proof walls at respective end portions in the lateral direction of the absorber 3.

As shown in FIGS. 3A to 3C, the absorbent body 3 has an absorbent core 3c, and a core wrap sheet 3rs that covers substantially the entire outer peripheral surface of the absorbent core 3c. The absorbent core 3c is obtained by forming a predetermined liquid absorbent material into an hourglass shape in plan view as an example of a predetermined shape (FIG. 2). Examples of the liquid absorbent material include liquid absorbent fibers such as pulp fibers, and liquid absorbent granules such as super absorbent polymer (hereinafter also referred to as SAP). Moreover, liquid-permeable sheets, such as tissue paper and a nonwoven fabric, are used for the core wrap sheet 3rs. The shape of the absorbent core 3c is not limited to the above-described substantially hourglass shape in plan view, and may be, for example, a substantially rectangular shape in plan view.

The top sheet 2 is formed of a non-woven fabric such as an air-through non-woven fabric, and has planar dimensions such as jumping from both sides in the longitudinal direction and both sides in the lateral direction of the absorbent body 3 as shown in FIGS. Further, the leak-barrier sheet 4 also has planar dimensions to protrude from both sides in the longitudinal direction and both sides in the lateral direction of the absorber 3, and is formed of a resin film such as a polyethylene film. And these two sheets 2 and 4 are joined mutually by adhesion, welding, etc. in the part which pops out from the absorber 3 in the longitudinal direction and the horizontal direction, and, thereby, the absorber 3 is held between the two sheets 2 and 4 ing.

As shown in FIG. 2, the exterior sheet 5 is formed of an appropriate non-woven fabric or the like, and forms the outer shape of the absorbent article 1. Then, the absorbent body 3 held between the both sheets 2 and 4 and the two sheets 2 and 4 is superposed on the skin side of the exterior sheet 5 while aligning the central positions in the lateral direction with one another and bonding or It integrates by welding etc. (FIG. 3A-FIG. 3C). In the integrated state, the absorber 3 extends over the first waist portion 1a, the crotch 1m, and the second waist portion 1b (FIG. 2).

As shown in FIG. 2, the three-dimensional gather sheets 6 and 6 (corresponding to the three-dimensional gather forming part) cover the respective end portions 2 e and 2 e in the lateral direction of the top sheet 2 from the skin side. It is provided in a pair corresponding to 2e. And each sheet 6 and 6 forms solid gathers 6g and 6g which stand up from the skin side of top sheet 2, respectively along a lengthwise direction. That is, each three-dimensional gather sheet 6 is fixed to the top sheet 2 with a hot melt adhesive or the like, and can not stand up in a strip-like base end 6k along the longitudinal direction. It has the standing part 6s which can stand on the skin side side by side in a horizontal direction. A rubber thread 6r is fixed as a solid gather elastic member 6r extending in the longitudinal direction at the distal end in the lateral direction of the rising portion 6s with a hot melt adhesive or the like in an elongated state in the longitudinal direction. Therefore, a contraction force is applied to the rising portion 6s in the vertical direction, and the rising portion 6s contracts in the vertical direction based on the contraction force, so that the rising portion 6s forms a plurality of creases in the thickness direction. Standing on the skin side of the body, thereby functioning as a solid gather 6g (FIG. 2, FIG. 3B).

In addition, as shown in FIG. 2, FIG. 3A, and FIG. 3C, the respective end portions 6sea, 6seb in the vertical direction of the rising portions 6s are in a state where the respective end portions 6sea, 6seb are put down on the top sheet 2. The fixing portions 6j, 6j fixed to the are formed in a strip shape along the longitudinal direction. That is, a hot melt adhesive is provided in the form of a strip along the longitudinal direction as fixing portions 6j, 6j between the portions corresponding to fixing portions 6j, 6j at each end 6sea, 6seb and top sheet 2. The respective end portions 6seLa and 6seLb are fixed to the top sheet 2 by the adhesive.
A suitable non-woven fabric can be exemplified as a suitable material for the three-dimensional gather sheet 6, and in this case an SMS non-woven fabric (spunbond / meltblown / spunbond non-woven fabric) is used. It is not limited to this at all.

The same three-dimensional gather sheet 6 extends to the outside in the lateral direction to almost the same position as the outer edge of the exterior sheet 5 as shown in FIGS. 2 and 3A to 3C, and At or near such an edge, it is integrated with the exterior sheet 5 by adhesion or welding. Then, thereby, the three-dimensional gather sheet 6 and the exterior sheet 5 cooperate with each other to form the first side flaps 1asf, 1asf and the second side flap 1bsf in the first waist portion 1a and the second waist portion 1b, respectively. , 1 bsf are formed. On the other hand, even in the crotch 1 m, similarly, the three-dimensional gather sheet 6 and the exterior sheet 5 are integrated by adhesion or welding at the above-mentioned edge or in the vicinity thereof. The crotch side flaps 1 msf and 1 msf described above are formed over a predetermined range.

Each of the crotch lower side flaps 1 msf and 1 msf is a portion that becomes the leg-surrounding opening 1 HL in the mounted state in cooperation with a part of the first side flap 1 asf and a part of the second side flap 1 bsf, respectively. That is, it constitutes a portion covering around the legs of the low weight child 101. Then, in order to form the leg gathers by contracting the crotch lower side flaps 1 msf in the longitudinal direction, in each crotch lower side flap 1 msf, the thread rubber 21 along the straight line in the longitudinal direction as the leg elastic 4 It is fixed by adhesion or the like in a stretched state in the direction. Therefore, when the extended state of the leg elastic member 21 is relieved, the crotch lower side flap 1 msf is contracted in the longitudinal direction to form a plurality of folds, and the folds become leg gathers.
Such a leg elastic member 21 is provided straddling at least the crotch 1 m and the second waist portion 1 b as shown in FIG. Moreover, in this example, as shown to FIG. 3B, although the leg elastic member 21 is interposed between the exterior sheet 5 and the solid gathers sheet 6, it is not restricted to this at all. For example, it may be adhered to the non-skin side of the exterior sheet 5 or may be adhered to the skin side of the three-dimensional gather sheet 6. Furthermore, although the rubber thread 21 is used as the leg elastic member 21 in this example, the present invention is not limited thereto. Flat rubber may be used, or a stretchable non-woven fabric or a stretch film having stretchability based on its own elasticity may be used.

As shown in FIG. 2, the fastening tapes 11 and 11 are respectively provided on the outer ends 1 bsfe 2 and 1 bsfe 2 in the lateral direction of the pair of second side flaps 1 bsf and 1 bsf. Each fastening tape 11 uses a horizontally long non-woven non-woven strip as a tape base 11a, and one end of the tape base 11a in the lateral direction is fixed to a part 1bk of the outer end 1bsfe2 of the second side flap 1bsf The other end portion protrudes laterally outward from the outer end portion 1bsfe2 of the second side flap 1bsf.
And male material 11m of a surface fastener is being fixed to the skin side of this projecting part, and also a plurality of locking projections (not shown) are provided on the skin side of male material 11m. . Therefore, the fastening protrusion 11 is locked to the first waist part 1a by the hooking protrusion of the male member 11m being caught on the target area 1at set on the non-skin side of the first waist part 1a. As the male member 11m, one known as a surface fastener can be applied. For example, a hook-like or T-shaped locking projection can be appropriately used.

As shown to FIG. 2 and FIG. 3A, the target area | region 1 at is made into the non-skin side of the exterior sheet 5 which is a non-skin side of the 1st waist part 1a. That is, in this example, since the exterior sheet 5 is a non-woven fabric and the sheet 5 can secure a sufficient locking force with the above-mentioned male material 11m, the non-skin side of the exterior sheet 5 itself is It is used as a locking target of 11 m of male material. However, the present invention is not limited to this, and a separate dedicated target tape may be used to form the target area 1 at.

And when mounting | wearing this absorbent article 1 to the low-weight child 101, a pair of fastening is pulled, pulling the 2nd waist part 1b to the both sides of the transverse direction with a pair of fastening tapes 11 and 11 of the 2nd waist part 1b. The tapes 11 are locked to the target area 1at of the first waist portion 1a (FIG. 4). Incidentally, in the example of FIG. 2, the tape base 11 a further protrudes outside in the lateral direction than the male member 11 m, and this protruding portion 11 ap is used as a pinching portion 11 ap pinching the fastening tape 11 on both sides. Function.

The basic configuration of the absorbent article 1 has been described above, but in the present embodiment, the absorbent article 1 is not only used as the tape-type disposable diaper 1 as described above, but can also be used as the absorbent pad 1p. ing. That is, as shown in FIG. 2, in each of the second side flaps 1bsf and 1bsf of the second waist portion 1b, the tearing lines 1c and 1c are formed in the unfolded state of the absorbent article 1 as shown in FIG. The fastening tapes 11, 11 can be removed by the cut lines 1c, 1c. And if the said tapes 11 and 11 are removed as shown in FIG. 5, the absorptive article 1 can be used as the absorptive pad 1p.

FIG. 6 is an enlarged view of an essential part for explaining the perforation 1c. As shown in FIG. 6, the cutting line 1c is a portion 1bk of the second waist portion 1b to which the tape base 11a of the fastening tape 11 is fixed (a hatched portion 1bk in FIG. , And the fastening tape fixing portion 1bk) is formed by perforations so that it can be cut out. In more detail, the tearing lines 1 c are respectively formed on the second side flaps 1 bsf in correspondence with the fastening tapes 11. And each perforation line 1c passes the position inside the transverse direction from fastening tape fixing part 1bk from the part 1bHB which becomes waist part opening part 1Hb among the 2nd trunk part 1b, respectively, and the 2nd waist part 1b It is formed of a route extending toward the portion 1bHL to be the leg opening 1HL.
Therefore, it is possible to remove all of the fastening tape 11 protruding in the lateral direction from the second waist portion 1b by cutting each perforation line 1c and cutting off the fastening tape fixing portion 1bk from the second waist portion 1b (see FIG. 5). And thereby, as shown in FIG. 5, the remaining part 1bc left at the center of the 2nd waist part 1b can be made into the state where there is no member which protrudes in the transverse direction, and as a result, the tearing line 1c The absorbent article 1p after cutting can be used without any problem as an absorbent pad 1p for which insertability is required.
For example, when inserting under the body of a low-weight child 101 in a lying posture as shown in FIG. 7A, the leg side of the same child 101 in the horizontal direction starting from the second waist part 1 bc from which the fastening tape 11 is removed If the absorbent article 1 p is inserted from the side of the head to the head side, the article 1 p can be spread quickly under the same child 101. Therefore, the article 1p can be used as the absorbent pad 1p. By the way, in the spread state of FIG. 7A and FIG. 7B, the second waist part 1bc is located on the ventral side of the same child 101, but while maintaining this state, as shown by the arrow in FIG. If the same pad 1p is bent upward at a portion 1m so that the buttocks and back of the same child 101 are covered from above with the first waist part 1a, the absorbent pad 1p can be attached to the same child 101. Complete.

In addition, in this example, when using as the absorptive pad 1p, the positional relationship of the vertical direction is reverse to the case of using as the tape type disposable diaper 1 so that it may understand from the above-mentioned. That is, the correspondence between the ventral side and the dorsal side of the low-weight child 101 and the first waist part 1a and the second waist part 1b is opposite to each other between the tape-type disposable diaper 1 and the absorbent pad 1p. And if it is this way, workers, such as a nurse who wears the same article 1 and 1p to the low-weight child 101, will be aware of one side and the other in the longitudinal direction and will do the mounting work , Makes it difficult to make mistakes in the vertical direction.

As shown in FIG. 6, the perforations of the cutting line 1c are schematically illustrated over the whole of the drawings in which the perforations are illustrated, corresponding to a plurality of linear slits (corresponding to through holes and including FIG. 6). Is a collection of That is, a plurality of linear slits (not shown) passing through the second side flaps 1bsf in the thickness direction are arranged along the direction in which the cutting lines 1c should extend. The length of the slits and the pitch of the slits are appropriately set in consideration of the cutting property and the like, but if a specific example is given here, the length of the slits can be exemplified by 1 mm to 3 mm, and The distance between the slits and the slits (ie, the length of the portion without slits located between the slits) can be, for example, 0.5 mm to 2 mm. Incidentally, it can also be said that the pitch of the above-mentioned slit is the sum value of the length of the slit and the above-mentioned interval.

Hereinafter, the cut line 1c will be described in more detail.
As shown in FIG. 6, the tearing line 1 c formed on one second side flap 1 bsf and the tearing line 1 c formed on the other second side flap 1 bsf are mutually in the lateral direction of the absorbent article 1. It is formed in line symmetry with respect to the center line C1. Each of the perforations 1c has a substantially J shape having a linear portion 1cL along the longitudinal direction and a curved portion 1cB of a curved shape.

The straight portion 1cL is a straight line parallel to the longitudinal direction starting from the portion 1bHB which becomes the waist opening 1HB of the second waist portion 1b, that is, the outer edge 1be1 in the longitudinal direction of the second waist portion 1b. It travels inward in the longitudinal direction, and reaches the same position as the position of the fastening tape 11 in the longitudinal direction, or a position slightly beyond the same position. And it is connected with curvilinear part 1cB in this position, and from there, the same curvilinear part 1cB extends in the inside of a lengthwise direction further. Specifically, the curvilinear portion 1cB is displaced outward in the lateral direction with a predetermined radius of curvature as advancing inward in the longitudinal direction, and finally, around the legs of the second waist portion 1b. The portion 1bHL which becomes the opening 1HL, that is, the lateral outer edge 1be2 of the second waist portion 1b is reached.
In addition, as shown in FIG. 2, the cutting line 1 c is such that the maximum value L 1 c of the distance between the pair of cutting lines 1 c and 1 c is smaller than the maximum value L 1 a of the lateral dimension of the first waist part 1 a. , 1c route is set.

Therefore, as shown in FIG. 5, after the fastening tape fixing portions 1bk and 1bk are cut off from the second side flaps 1bsf and 1bsf of the second waist portion 1b at the tearing lines 1c and 1c, respectively, The maximum value L1bc of the lateral dimension of the remaining part 1bc of the two torso portion 1b is smaller than the maximum value L1a of the lateral dimension of the first torso portion 1a. Therefore, as shown in FIGS. 7A and 7B, the absorbent pad 1p is placed with the remaining portion 1bc at the center of the second waist part 1b at the top, and the lower part of the body of the low-weight child 101 in a lying posture as shown in FIGS. 7A and 7B. The plug can be smoothly inserted into the plug. And thereby, the same pad 1p is suitably used as a thing excellent in pluggability.

Further, as shown in FIG. 5, the remaining portion 1bc remaining in the second waist portion 1b after being cut off by the tearing lines 1c, 1c has a narrow portion 1bc1 having a small dimension in the lateral direction at a position outside in the longitudinal direction. The wide width portion 1bc2 having a larger dimension in the horizontal direction than the narrow width portion 1bc1 is provided on the inner side in the longitudinal direction than the narrow width portion 1bc1. Therefore, when inserting the absorbent pad 1p with the second waist portion 1b at the top, since the narrow portion 1bc1 having a small lateral dimension is inserted at the top, the pad 1p can exhibit good insertability.

Furthermore, according to the route of the cutting line 1c, when the article 1 is used as the tape-type disposable diaper 1 as shown in FIG. 8A and FIG. 8B, the person to be worn 101 in a lying posture is not turned over. The article 1 can be removed from the wear target person 101 in the lying position, which is suitable for the idea of minimum handling. The details are as follows. First, in a general wearing mode when the article 1 is used as the tape-type disposable diaper 1, as shown in FIG. 8A, the second waist part 1b to which the fastening tape 11 is fixed is a person to be worn The article 1 is attached to the person to be worn 101 so as to be located on the back side of the seat 101. Therefore, in the reclining posture, the second waist part 1b is usually located above in the vertical direction, but here, the cutting line 1c is formed on the second waist part 1b. Therefore, as shown to FIG. 8B, the part 1bk to which the fastening tape 11 was fixed among the said 2nd trunk parts 1b can be cut off with the perforation line 1c. And thereby, the fastening tape 11 can be removed from the center part 1bc (FIG. 6) of the horizontal direction in the 2nd waist part 1b with a lying posture, and as a result, the absorbent article 1 is kept with the same posture. It can be deployed (FIG. 8B). And thereby, the absorptive article 1 as diaper 1 can be promptly removed from wearing object person 101 of a reclining posture.

Moreover, as shown in FIG. 6, according to the said route, the tearing-off line 1c passes along the position inside a transverse direction rather than the fastening tape fixing | fixed part 1bk among the 2nd waist parts 1b. Therefore, when cutting off the fixing portion 1bk, it is not necessary to cut the fastening tape 11 at all, thereby making it possible to reduce the force required to cut the cutting line 1c. And as a result, when cutting the cutting line 1c in order to remove the diaper 1 from the low-weight child 101 in the reclining posture, the external load that can be given to the child 101 can be reduced, which is also an idea of minimum handling. It is good for you.

Furthermore, if it has the above-mentioned curvilinear part 1cB, the tearing line 1c can be made to reach the lateral outer edge 1be2 of the 2nd waist part 1b by comparatively short route. That is, as shown in FIG. 6, it is possible to end the route of the cutting line 1c without greatly extending the inside in the longitudinal direction. And thereby, the problem which may occur when the route of the tearing line 1c is largely extended inward in the longitudinal direction, for example, when the route reaches the first side flap 1asf (FIG. 2), the positioning posture is low It is possible to effectively prevent that a part of the cutting line 1c is pinched by the abdomen of the weight child 101 and the leg opened in the M-shape and it becomes difficult to cut.

By the way, in the example of this FIG. 6, although the tearing-off line 1c is completely settled in the 2nd side flap 1bsf, it is not restricted to this at all. That is, depending on the case, a part of the tearing line 1c may protrude toward the crotch side flap 1 msf. However, if the amount of protrusion is too large, it becomes difficult to cut the above-mentioned tearing line 1c because it becomes easy to be inserted between the abdomen of the low-weight child 101 and the M-shaped leg or the cutting length becomes long. It can lead to the following problem.

Further, in the example of FIG. 6, a plurality of sheets 4, 5, 6 exist at the formation position of the linear portion 1 cL. Specifically, the three-dimensional gather sheet 6, the leakproof sheet 4 and the exterior sheet 5 are present from the skin side in the thickness direction, and the number of sheets stacked is three. Therefore, in the linear portion 1cL, perforations are formed through the three stacked sheets 4, 5 and 6.
On the other hand, as described above, the formation position of the curvilinear portion 1cB is displaced outward in the lateral direction as it proceeds inward in the longitudinal direction. Therefore, in the process of moving from one end of the curved portion 1cB to the other end, the number of stacked sheets changes. That is, as shown in the left half of FIG. 6, in the portion 1cB1 of the predetermined range continuous to the linear portion 1cL in the curved portion 1cB, the number of laminated sheets is three in the same manner as the linear portion 1cL above. However, in the portion 1cB2 of the curved portion 1cB adjacent to the inside of the predetermined range in the longitudinal direction than the portion 1cB1 of the predetermined range, the leakproof sheet 4 does not exist, so the three-dimensional gather sheet 6, the exterior sheet 5 and It has a two-piece configuration. Therefore, in the former portion 1cB1, perforations are formed by penetrating the three sheets 4, 5 and 6 but in the latter portion 1cB2, perforations are formed by penetrating the two sheets 5 and 6 It is formed.
And even in this way, even in the portion 1cB2 of the curved portion 1cB, when the number of laminated sheets is small, the portion 1cB2 is relatively easy to cut. Therefore, it is possible to facilitate cutting of a curve that is generally considered to be more difficult than a straight line, and as a result, it is possible to cut the curved portion 1cB accurately along the curved target shape.

Furthermore, in this example, as described above with reference to FIG. 6, the tearing line 1 c is formed in the second side flap 1 bsf, and hence the tearing line 1 c is outside the absorber 3 in the lateral direction. It is formed in the position of. Further, as can be seen with reference to FIG. 6, the cutting line 1 c is formed at a position outside in the lateral direction than the base end 6 k and the standing portion 6 s of the three-dimensional gather sheet 6.
Accordingly, even if the cutting line 1c is cut, the base end 6k and the standing portion 6s of the absorber 3 and the three-dimensional gather sheet 6 are not affected at all, and are maintained in a healthy state. And thereby, also when using as the absorptive pad 1p, the absorber 3 and the standing part 6s can exhibit the retention function of excrement without a problem, and, thereby, the same pad 1p is high leakproof. You can play sex.

Further, as described above, the second waist portion 1b is provided with the fixing portion 6j for fixing the end portion 6seb in the vertical direction of the rising portion 6s in a state of putting it down, as shown in FIG. The cutting line 1c is formed at a position outside the fixing portion 6j in the lateral direction. Therefore, the said fixing | fixed part 6j can be left to the absorbent pad 1p which is the absorbent article 1p after having been cut off by the tearing-off line 1c. Then, since the contractile force acting on the rising portion 6s is input to the fixed portion 6j, the absorbent pad 1p can be quickly curved so that the non-skin side in the thickness direction becomes the inner peripheral side. Thus, the pad 1p can be in close contact with the body of the low-weight child 101 quickly along the curved body. And this also contributes to the improvement of the leakproofness of absorptive pad 1p.

By the way, speaking of the positional relationship with the top sheet 2, the cutting line 1c is formed at a position outside the sheet 2 in the lateral direction, that is, the top sheet 2 is present at the position of the cutting line 1c. I did not. Therefore, the number of stacked sheets at the position of the cutting line 1c can be reduced, which contributes to the improvement of the easiness of cutting the cutting line 1c.

Here, from the viewpoint of making it easier to cut the cutting line 1c, desirably, the sheet 4 is disposed so that the stretching direction at the time of production of the resin film forming the leakproof sheet 4 of FIG. Good to have been. That is, in general, the resin film is easily cut along the stretching direction because the resin orientation is aligned in the stretching direction. Therefore, if the stretching direction is along the longitudinal direction, the leak-barrier sheet 4 can be easily cut along the longitudinal direction, and as a result, the above-mentioned linear portion 1cL in which the sheet 4 is present can be obtained. It becomes possible to cut accurately along the vertical direction.

Further, when cutting the curved portion 1cB continuously to the linear portion 1cL of the cutting line 1c as shown in FIG. 6, the momentum when the linear portion 1cL is cut extends the portion 1cL as it is. It is easy to erroneously cut the position on or near the line, that is, there is a possibility that the position deviated from the curvilinear portion 1cB is erroneously cut. In this example, in this example, the following measures are taken There is.
First, although the leg elastic member 21 is located near the tearing line 1c, the leg elastic member 21 and the curvilinear portion 1cB of the tearing line 1c when viewed from the thickness direction here And are intersected at a predetermined intersection position P1c. More specifically, as shown in the right half of FIG. 6, when the curvilinear portion 1cB is virtually divided into a portion 1cBa on the side of the waist opening 1HB and a portion 1cBb on the side of the waist opening 1HL, The intersection position P1c with the member 21 is included in the portion 1cBa on the side of the waist opening 1HB of the former, and therefore, the intersection position P1c is relatively the boundary position PLB of the linear portion 1cL and the curvilinear portion 1cB. It is located in the vicinity.

Therefore, in the process of cutting the curvilinear portion 1cB continuously to the linear portion 1cL of the cutting line 1c, when the cutting position approaches the intersection position P1c near the boundary position PLB, the linear portion The force of the longitudinal cutting attached at 1 cL is absorbed by the elastic deformation of the leg elastic member 21 and the linear cutting operation along the longitudinal direction is restrained. And thereby, trajectory correction to curvilinear part 1cB can be performed promptly, and as a result, it becomes possible to cut correctly along curvilinear part 1cB.

Furthermore, according to the intersecting relationship between the above-mentioned tearing line 1c and the leg elastics 21 (corresponding to the elastic member), after cutting the tearing line 1c, most of the leg elastics 21 are the absorbent pad 1p. Remain in That is, as shown in FIG. 6, according to this crossing relationship, over the predetermined range in the longitudinal direction of the second waist portion 1b, the leg elastics 21 are arranged next to each other in the lateral direction of the perforation 1c. And, at least in a part A21 of the predetermined range, the leg elastics 21 are positioned laterally inside the tear line 1c. Therefore, the leg elastic member 21 remains in the remaining portion 1 bc of the second waist portion 1 b of the absorbent pad 1 p at least in the portion A 21 after the cutting line 1 c is cut.

Therefore, with the contraction force of the leg elastic member 21, as shown by the arrow in FIG. 7A, the remaining part 1bc of the second waist part 1b of the same pad 1p can rise to the skin side in the thickness direction. Therefore, when the absorbent pad 1p is inserted and arranged so that the first waist portion 1a is positioned on the back side while the remaining portion 1bc of the second waist portion 1b is positioned on the ventral side of the low-weight child 101 in the lying position. The remaining portion 1 bc of the second waist portion 1 b standing on the skin side comes in contact with the abdomen of the baby 101. And thereby, the clearance gap between the abdomen of the same child 101 and the remaining part 1bc of the 2nd waist part 1b can be made small, as a result, the absorptive pad 1p concerned can play high leakproofness.

Moreover, in the example of FIG. 9, the easiness of cutting of the perforation line 1c is made to differ according to the position of the vertical direction by devising perforation. For example, when the cutting line 1c is virtually divided into three portions 1c1, 1c2, 1c3 in the vertical direction, the easiness of cutting is set corresponding to the portions 1c1, 1c2, 1c3. Specifically, a first portion 1c1 (corresponding to a first cutting line portion) which is one portion 1c1 of the three portions 1c1, 1c2, 1c3 is a portion 1bHB which becomes the waist opening 1HB of the second waist portion 1b. The first portion 1c1 has perforations that are easy to cut. In addition, another portion 1c2, which is a second portion 1c2 (corresponding to a second cutting line portion), is positioned to include the same position as the fastening tape fixing portion 1bk with respect to the position in the vertical direction. The portion 1c2 has perforations that are more difficult to cut than the first portion 1c1. Furthermore, the remaining third portion 1c3, which is the third portion 1c3, is the above-mentioned curved portion 1cB, but this portion 1c3 has an easy-to-cut perforation having the same specifications as the first portion 1c1.

And if it does in this way, in order to mount the absorbent article 1 on the low-weight child 101 as the tape type disposable diaper 1, when pulling each fastening tape 11,11 outside in the lateral direction, the above-mentioned It is possible to effectively prevent breakage of the two portions 1c2 based on the perforations of the second portions 1c2 that are difficult to cut. Further, when removing the diaper 1 from the low-weight baby 101 or when using the absorbent article 1 as the absorbent pad 1p, the above-mentioned waist opening 1HB based on the perforation line of the first portion 1c1 which is easy to cut The third portion 1c3 can be easily cut from the portion 1bHB, and the third portion 1c3 is also accurately curved along the curved target shape on the basis of the perforations that are easy to cut. Can be cut into

Incidentally, the setting of the above-mentioned easy-to-cut perforations and the difficult-to-cut perforations can be realized by changing the lengths of the slits provided in the perforations, and in this example, this is done. That is, in this example, by keeping the slit pitch constant and making the slit lengths different, the ratio of the slit length to the unit length in the direction in which the perforation line 1c extends is the portion 1c2 The portions 1c1 and 1c3 differ from each other, and generally, the larger the ratio, the easier the cutting is, and the smaller the ratio, the more difficult to cut. Therefore, in this example, the ratio in the second part 1c2 is smaller than the ratio in the first part 1c1 and the ratio in the third part 1c3.

FIG. 10 is an explanatory view of a perforated line 1c 'of the first modified example. In the above-described embodiment, as shown in FIG. 6, the number of stacked sheets changes from three sheets to two sheets in accordance with the position of the cutting line 1c. In this first modification, the cutting line 1c is used. The number of laminated sheets is constant over the entire length of the sheet. That is, as shown in FIG. 10, the position of the perforation line 1c 'of this first modification is shifted to the outside in the lateral direction than the perforation line 1c of the embodiment of FIG. The tearing line 1 c ′ is located laterally outside the leak-barrier sheet 4 along the entire length thereof. And only two sheets of the solid gather sheet 6 and the exterior sheet 5 exist in this position. Therefore, the perforations of the perforations 1c 'are formed by penetrating the two sheets 5 and 6 in the thickness direction, and since the number of laminated sheets is small, the perforations 1c with good cuttability. 'Can be cut. The other points are almost the same as those of the above-described embodiment, so the same reference numerals are given to the same components and the description thereof will be omitted.

FIG. 11 is an explanatory view of a perforated line 1c '' of the second modified example. In the above-described embodiment and the first modification, as shown in FIGS. 6 and 10, the cutting lines 1c and 1c ′ have the linear portion 1cL and the curvilinear portion 1cB. In this case, the perforation line 1c ′ ′ does not have the curvilinear portion 1cB, but has only the linear portion 1cL. That is, in the second modification, the perforation line 1c ′ ′ is further shifted outward in the lateral direction than the first modification, whereby only one linear portion 1cL along the vertical direction is obtained. The fastening tape fixing portion 1bk can be cut out. And since it is only linear part 1cL according to such a tearing line 1c '', the cutting is easy, As a result, it can be cut accurately, without being largely displaced from tearing line 1c '' It is. In addition, only the two sheets of the solid gathers sheet 6 and the exterior sheet 5 exist also in the position of this tearing-off line 1c ''. Therefore, the perforations of the tearing line 1 c ′ ′ are formed by penetrating the two sheets 5 and 6 in the thickness direction.

FIG. 12 is an explanatory view of a perforation line 1 c ′ ′ ′ of the third modified example. In any of the cut lines 1c, 1c ′ and 1c ′ ′ of the above-described embodiment (FIG. 6), the first modification (FIG. 10) and the second modification (FIG. 11), among the second waist portion 1b The portion 1bHB serving as the waist opening 1HB extends from the portion 1bHB serving as the leg circumference opening 1HL to the portion 1bHL so as to form a substantially J shape or a straight line. Is mainly different in that it does not take such a route. That is, as shown in FIG. 12, a cutting line 1c '' 'is formed in a substantially U shape so as to surround the fastening tape fixing portion 1bk from three sides. And in this tearing-off line 1c '' ', the starting end Ps is located in the outermost edge 1bsfee in the lateral direction of the second side flap 1bsf of the second waist portion 1b, and from there, it is substantially U-shaped The fastening tape fixing portion 1bk extends so as to enter the inner peripheral side of the route, and finally reaches the outermost end edge 1bsfee in the lateral direction of the second side flap 1bsf as with the above-mentioned starting end Ps, and the outermost The position Pe leading to the edge 1 bsfee is taken as the end Pe of the cutting line 1 c ′ ′ ′. The other points are almost the same as those of the above-described embodiment and the like, so the same reference numerals are given to the same components and the description thereof will be omitted.

Furthermore, in some cases, a cutout line 1ca similar to the cutout line 1c of the second waist part 1b described above may be formed in the first waist part 1a. FIG. 13 is a schematic plan view of the absorbent article 1 ′ ′ ′ ′ having the tear line 1 ca. In this example, substantially J-shaped cut lines 1ca and 1ca having a similar shape to the cut lines 1c and 1c of the second waist part 1b are also formed on the first side flaps 1asf and 1asf of the first waist part 1a. There is. Then, if the cutting lines 1ca and 1ca are cut, the maximum value L1ac of the lateral dimension of the remaining portion 1ac remaining in the lateral center of the first waist portion 1a is the lateral width of the first waist portion 1a before the clipping. It becomes smaller than maximum value L1a of a size. Therefore, when inserting the absorbent article 1 ′ ′ ′ ′ into an appropriate insertion target with the remaining portion 1 ac of the first waist portion 1 a after cutting out as the head, the insertion property can be improved.

Incidentally, this substantially J-shaped cutout line 1ca also has a linear portion 1caL along the longitudinal direction at the position on the outer side in the longitudinal direction, and a curvilinear portion at the position on the inner side in the longitudinal direction than the linear portion 1caL The lateral portion of the linear portion 1 caL is aligned with the position of the linear portion 1 cL of the cutout line 1 c of the second waist portion 1 b. And if aligned in this way, the remaining part 1ac of the first waist part 1a and the remaining part 1bc of the second waist part 1b of the absorbent article 1 ′ ′ ′ ′ after cutting the perforations 1c, 1c, 1ca, 1ca Since and have mutually the same size in the lateral direction, it is possible to play a good pluggability as the head in the plugging direction.

By the way, at the beginning, although it stated that the diaper 1 of this embodiment is particularly suitable for low-weight children 101 having a weight of 3000 grams or less, the diaper 1 can effectively solve the above-mentioned problems associated with positioning posture and minimum handling. If anything is taken into consideration, it is considered that the diaper 1 is more effective when it is easy to be in the positioning posture and when minimum handling is more required. And such a case is when the weight is lighter.
Therefore, the diaper 1 of the present embodiment is desirably used for low birth weight children of 500 grams or more and less than 2500 grams, and more desirably for very low birth weight children of 1000 grams or more and less than 1500 grams. Good, and even more desirably, for very low birth weight infants less than 1000 grams.

Moreover, since the diaper 1 of this embodiment is specialized for low weight children 101, it is formed smaller than the existing diaper 1 for newborns. For example, while the product length of the diaper for newborns is 365 mm and the circumferential length L1HB of the waist opening 1HB in the mounted state is 304 mm, the product length L1 (FIG. 2) in the diaper 1 of this embodiment. The circumference L1HB of the waist opening 1HB in the mounted state is 160 to 295 mm.

The product length L1 is measured, for example, in the unfolded state of the diaper 1. That is, as shown in FIG. 2, in the unfolded state, the fastening of the fastening tapes 11, 11 to the target area 1at is first released, so that the first waist portion 1a, the crotch 1m and the second waist portion 1b are vertical. Along the direction, until the contraction of the solid gather sheet 6 by the solid gather elastic member 6r and the contraction of the crotch side flaps 1 msf and 1 msf based on the leg elastic members 21 and 21 disappear in the vertical direction. The diaper 1 is in a stretched state. Then, the maximum dimension L1 in the longitudinal direction in the stretched state is measured, and the measured value becomes the product length L1.

On the other hand, with respect to the circumferential length L1HB of the above-mentioned waist opening portion 1HB, the pair of fastening tapes 11, 11 are measured in a locked state in which the fastening tapes overlap. FIG. 14 is an explanatory view thereof. In the following, for convenience of explanation, the fastening tape 11 of the second side flap 1bsf located on the left side in FIG. 14 is referred to as "left side tape 11-1", and similarly, the second side flap located on the right side The 1 bsf fastening tape 11 is called "right side tape 11-2".
First, in preparation for measurement, the two fastening tapes 11-1 and 11-2 are put in the fastening state of the fastening tape overlap form. That is, as shown in FIG. 14, after locking the male material 11m of the left side tape 11-1 to the target area 1at of the first waist part 1a, the male material 11m of the right side tape 11-2 is made of the left side tape 11-1. Lock on non-skin side 11-1s. However, at that time, the front end 11-2e of the right side tape 11-2 is the left side tape 11 while aligning the longitudinal center positions C11-1 and C11-2 of the tapes 11-1 and 11-2 with each other. Align so that it aligns with the end 11me of the root side of the male material 11m of -1. And by this, it will be in the locked state of a fastening tape overlap form.

Then, the waist opening 1HB formed on the basis of the locked state is extended until the contraction due to the waist elastic member 21 is just lost. Then, in such an extended state, the circumferential length L1HB of the waist opening 1HB is measured, whereby the circumferential length L1HB is obtained.

Incidentally, examples of the product length L1 of low birth weight infants and the circumferential length L1HB of waist opening 1HB include 310 mm and 273.5 mm, respectively, and the product length L1 and waist opening of very low birth weight infants 270 mm and 220 mm can be mentioned as an example of perimeter L1HB of part 1HB, and 230 mm and 219 mm can be mentioned as an example of perimeter L1HB of product length L1 and waist opening 1HB of very low birth weight children, respectively. Can be mentioned.

=== Other Embodiments ===
As mentioned above, although embodiment of this invention was described, said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. Further, it goes without saying that the present invention can be modified or improved without departing from the gist thereof, and that the present invention includes equivalents thereof. For example, the following modifications are possible.

In the above-mentioned embodiment, although the perforation was mentioned as an example of perforations 1c, 1c ', 1c ", 1c'", and 1ca, it does not restrict to this at all. That is, as long as the tearing lines 1c, 1c ', 1c ", 1c'" and 1ca are easier to cut than the surrounding portion, it may be other than the perforations. For example, instead of linear slits along the direction in which the cutting lines 1c, 1c ′, 1c ′ ′, 1c ′ ′ ′, 1ca should extend, circular or corrugated slits may be used, or through holes The plane shape of may be a circle, an ellipse or the like. Furthermore, the plurality of through holes may not be aligned. For example, a plurality of recesses may be formed by squeezing or squeeze welding in the thickness direction, and these recesses may form cutting lines 1c, 1c ', 1c ", 1c"', 1ca.

In the above embodiment, as shown in FIGS. 6, 10, 11, and 12, the tearing lines 1c, 1c ', 1c'',1c''' are used as the second side flaps 1bsf of the second waist portion 1b. Thus, the portion 1bk of the second waist portion 1b to which the tape base 11a of the fastening tape 11 is fixed is cut out together with the fastening tape 11. However, the present invention is not limited thereto. That is, as shown in FIG. 15, the tearing line 1c11a may be formed only in the fastening tape 11 without forming a tearing line in the second side flap 1bsf. The details are as follows. In the case of using the absorbent article 1 as the absorbent pad 1p, first of all, the projecting portion 11p of the fastening tape 11 that protrudes in the lateral direction from the second waist portion 1b is a hindrance. Therefore, at least when the protrusion 11p is cut off from the second waist portion 1b, the absorbent article 1p after being cut off can be used without any problem as the absorbent pad 1p. Therefore, as shown in FIG. 15, the cutting line 1 c 11 a may be formed only for the tape base 11 a of the fastening tape 11.
Here, to describe in detail the formation position of the cutting line 1c11a, the cutting line 1c11a is the outermost end edge in the lateral direction of the side flap 1bsf of the second waist portion 1b of the tape base material 11a of the fastening tape 11. It is formed along the vertical direction at the same position as 1bsfee. Therefore, when the cutting line 1c11a is cut, the protruding portion 11p of the fastening tape 11 can be removed. That is, it is possible to make a state in which there is no partially projecting portion in the lateral direction from the second waist portion 1b. And if it is this way, when inserting the same pad 1p with the second waist part 1b as the head and the lower side of the low weight child 101 in the lying posture, large hooking is suppressed and the same pad 1p is quickly It can be inserted into the
