Description

The present invention relates to an absorbent article such as a disposable diaper, and more particularly to an absorbent article that can be used by attaching a separate absorbent pad.

Conventionally, for the purpose of reducing the economical and labor burden associated with the treatment of excrement such as urine, an absorbent pad has been used by superimposing it on the skin-facing surface of an absorbent article such as a disposable diaper. .. For example, a urine absorbing pad, which is a type of absorption pad, is fixed on the surface sheet of a disposable diaper worn by an adult whose physical function has deteriorated or an adult who has been weakened by a disease (mostly elderly people) to collect incontinent urine. When used for absorption and retention, when the amount of urine excreted is relatively small, only the urine absorbing pad needs to be replaced, and the frequency of changing disposable diapers can be reduced.

Since the absorbent pad exhibits its original performance only when it is attached to a predetermined appropriate position in the absorbent article, a positioning operation is important when the absorbent pad is attached to the absorbent article. However, in such a positioning operation, the mounting position of the absorbent pad cannot be determined by a single operation due to the user's own preference for the mounting position of the absorbent pad, and the absorbent pad can be attached to and detached from the absorbent article many times. Is often repeated. However, the absorbent pad is attached to the absorbent article by engaging the adhesive tape or hook material attached to the non-skin facing side of the absorbent pad with the surface sheet portion made of the non-woven fabric in the absorbent article. In many cases, if the absorbent pad is repeatedly attached and detached, the absorbent article may be physically damaged, resulting in inconvenience such as being unable to attach the absorbent pad.

Therefore, various improved techniques for smoothly positioning the absorption pad have been proposed. For example, Patent Document 1 includes a front surface sheet forming a skin facing surface, a back surface sheet forming a non-skin facing surface, and an absorber interposed between the two sheets, and vertically corresponding to the front-back direction of the wearer. In an absorbent article having a ventral, inseam and dorsal portion along the direction, a pair of visible color markers indicating the attachment position of the absorbent pad on the surface sheet at least one of the ventral and dorsal portions. It is described that the portions are arranged symmetrically with respect to the lateral centerline. A plurality of color marking portions are arranged in different colors corresponding to the edge portions of a plurality of types of absorption pads having different sizes, whereby the corresponding absorption pad types can be easily selected by color. It is said that the corners of absorption pads of different sizes can be easily aligned to the mounting position simply by aligning them with the corresponding pair of color markings. Further, in Patent Document 2, not the absorbent article to which the absorbent pad is attached, but the absorbent pad itself, specifically, the exterior sheet forming the facing surface of the absorbent article to the skin facing surface of the absorbent pad. It is described that the front and back notation is printed directly.

Further, for a purpose different from the positioning of the absorbent pad, it has been conventionally performed to visually display various information on the absorbent article. For example, in Patent Document 3, when a plurality of types of pants-type disposable diapers are stored in layers, the absorbent body of the diaper is used for the purpose of facilitating the operation of selecting and taking out a specific diaper from the stacks. A display unit that displays identification information such as the size and front-back direction of each diaper so that it can be confirmed from the side position of each diaper when multiple diapers are stacked so that the ventral and dorsal parts overlap. In the embodiment, the sheet constituting the crotch portion located between the ventral portion and the dorsal portion is folded back, and the display portion is formed on the outer surface of the folded portion. It is shown.

For example, when a wearer of a pants-type disposable diaper wears an absorbent pad by himself / herself, he / she inserts both feet into the leg opening of the diaper and pulls the diaper up to the height of the knee. While visually checking the inner surface (skin facing surface) of the diaper through the waist opening of the diaper, the absorption pad is often positioned with respect to the inner surface, so that it is easy to distinguish between the front and back of the diaper. However, a technique capable of smoothly performing such a positioning operation has not yet been provided.

Therefore, an object of the present invention is to provide an absorbent article which can smoothly perform a positioning operation when the absorbent pad is attached and can sufficiently obtain the effect of the combined use of the absorbent pad.

The present invention is an absorbent article comprising an absorbent body provided with an absorber capable of absorbing and holding excreted body fluid, and having a vertical direction corresponding to the front-back direction of the wearer and a horizontal direction orthogonal to the vertical direction. ,

Hereinafter, the present invention will be described based on the preferred embodiment thereof with reference to the drawings. 1 to 3 show a pants-type disposable diaper 1 which is an embodiment of the absorbent article of the present invention. The diaper 1 has an absorbent main body 2 provided with an absorbent body 23 capable of absorbing and holding the excreted body fluid, and is arranged on the non-skin facing surface side of the absorbent main body 2 to fix the absorbent main body 2. It includes an exterior body 3, and has a vertical direction X corresponding to the front-back direction of the wearer and a horizontal direction Y orthogonal to the vertical direction X.

In the present specification, the "skin facing surface" is a surface of the absorbent article or a component thereof (for example, an absorbent main body) that is directed toward the skin side of the wearer when the absorbent article is worn, that is, relatively of the wearer. The side closer to the skin, the "non-skin facing surface" is the side of the absorbent article or its constituents that is opposite to the skin side when the absorbent article is worn, that is, toward the side relatively far from the wearer's skin. It is the surface to be. In addition, "when worn" here means a state in which the normal proper wearing position, that is, the correct wearing position of the absorbent article is maintained, and the absorbent article is in a state deviated from the wearing position. Does not include.

In the diaper 1, both side edges FS and RS along the vertical direction X of the exterior body 3 on the front body 1F and the rear body 1R are bonded to each other by known bonding means such as an adhesive, a heat seal, and an ultrasonic seal. Then, as shown in FIG. 1, a pair of side seal portions S, S, a waist opening WH through which the wearer's body is passed, and a pair of leg openings LH, LH through which the wearer's lower limbs are passed. Is formed. As shown in FIG. 2, the front body 1F is the front side (ventral side) of the wearer's body when worn, with reference to the vertical center line CLx extending in the horizontal direction Y by dividing the diaper 1 or the exterior body 3 into two in the vertical direction X. ), And the back body 1R is a part that covers the back side (dorsal side) of the wearer's body.

The diaper 1 is a ventral portion 1A arranged on the ventral side of the wearer when worn, a dorsal portion 1C arranged on the dorsal side, and an inseam 1B located between them and arranged on the wearer's crotch portion. have. The vertical direction X of the diaper 1 is a direction extending between the front body 1F and the back body 1R, that is, a direction extending between the ventral side portion 1A and the dorsal side portion 1C via the inseam 1B, and is absorbent. It coincides with the longitudinal direction of the main body 2. The ventral part 1A is a part of the front body 1F, the dorsal part 1C is a part of the back body 1R, and the inseam 1B straddles the front body 1F and the back body 1R. The ventral side portion 1A and the dorsal side portion 1C are both portions at the same positions as the side seal portion S in the vertical direction X, and are waist circumference portions corresponding to the wearer's waist circumference when the diaper 1 is worn. The inseam 1B is a region in which notches for forming leg openings LH and LH are formed on both side edges of the exterior body 3 along the vertical direction X. The inseam 1B has an excretion portion facing portion that is arranged to face the wearer's excretion portion when the diaper 1 is worn, and the excretion portion facing portion is usually the central portion (vertical center) of the diaper 1 in the vertical direction X. It is located on or near the line CLx).

The absorbent body 2 has a rectangular shape in a plan view as shown by the outline in FIG. 2, and its longitudinal direction is aligned with the vertical direction X of the diaper 1 in the expanded and extended state, and the lateral direction Y of the exterior body 3 is matched. It is arranged in the central portion of the above and is joined to the exterior body 3 by an adhesive. The exterior body 3 forms the outer shape of the diaper 1 in the expanded and extended state as shown in FIG. 2, and the peripheral edge of the exterior body 3 forms the contour line of the diaper 1 in that state. The "expanded and extended state" of the diaper 1 means that the diaper 1 is separated by the side seal portion S to be in the expanded state, and the diaper 1 in the expanded state is extended with the elastic members of each part to have design dimensions (the influence of the elastic members is completely affected). It means the state of being expanded until it becomes the same as the dimensions when it is expanded in a plane with it removed.

As shown in FIG. 2, the absorbent main body 2 is a liquid-permeable front sheet 21 that forms a skin-facing surface, and a liquid-impermeable, liquid-impermeable, or water-repellent back sheet 22 that forms a non-skin facing surface. , And a liquid-retaining absorber 23 interposed between the sheets 21 and 22, and these are integrated by a known joining means such as an adhesive. The absorber 23 has a rectangular shape in a plan view and forms the outer shape of the absorbent body 2. As the front surface sheet 21, the back surface sheet 22, and the absorber 23, various types conventionally used for this kind of absorbent article can be used without particular limitation. For example, various non-woven fabrics, perforated films and the like can be used as the front surface sheet 21, and a resin film or a laminate of a resin film and a non-woven fabric or the like can be used as the back surface sheet 22. As the absorber 23, one having an absorbent core composed of an aggregate of fiber materials such as pulp fibers or water-absorbent polymer particles can be used, and the outer surface of the absorbent core is liquid permeable. It may be covered with a core wrap sheet.

As shown in FIG. 2, a pair of leak-proof cuffs 24 made of a liquid-resistant or water-repellent and breathable sheet material are placed on the left and right sides of the absorbent body 2 on the skin-facing surface along the vertical direction X. , 24 are provided. One or more thread-shaped elastic members 25 for forming a leak-proof cuff are arranged in an extended state in the vicinity of the free end of each leak-proof cuff 24. The leak-proof cuff 26 stands up at least at the inseam 1B due to the elastic member 25 arranged in the extended state contracting when the diaper 1 is worn, whereby the excrement liquid such as urine flows out in the lateral direction Y. To prevent.

As shown in FIG. 2, the exterior body 3 has a ventral portion 1A which is a waist circumference portion of the front body 1F, a dorsal portion 1C which is a waist circumference portion of the rear body 1R, and a ventral side portion 1A and a dorsal portion 1C. It is arranged over the inseam 1B sandwiched between the two, and both side edges along the vertical direction X are curved inward in an arc shape in the inseam 1B to form a pair of leg edges LS and LS. In a plan view as shown in FIG. 2, the central region of the vertical direction X has an hourglass-like shape constricted inward in the horizontal direction Y.

As shown in FIG. 3, the exterior body 3 includes a laminated body of an outer layer sheet 31 and an inner layer sheet 32. In the wearing state of the diaper 1, the outer layer sheet 31 is located on the side far from the wearer's body to form the non-skin facing surface (outer surface) of the diaper 1, and the inner layer sheet 32 is on the side closer to the wearer's body. Positioned to form the skin facing surface (inner surface) of the diaper 1. The outer layer sheet 31 and the inner layer sheet 32 are joined by an adhesive at a predetermined portion. The outer layer sheet 31 has the same shape and dimensions as the inner layer sheet 32, and when both sheets 31 and 32 are laminated, the outer layer sheet 31 is outward from the end portion of the inner layer sheet 32 on the ventral side A side in the vertical direction X. It has a ventral extending portion 31AE extending outward and a dorsal extending portion 31CE extending outward from the end portion of the inner layer sheet 32 on the dorsal side C side in the vertical direction X. As shown in FIG. 2, the two extending portions 31AE and 31CE of the outer layer sheet 31 cover both ends of the absorbent body 2 arranged and fixed on the inner layer sheet 32 in the vertical direction X, respectively. It is folded back to the side and fixed to other components of the diaper 1 facing both the extending portions 31AE and 31CE by an adhesive. As the outer layer sheet 31 and the inner layer sheet 32, various types conventionally used as an exterior body in this type of absorbent article can be used without particular limitation, and for example, a spunbonded nonwoven fabric, an air-through nonwoven fabric, and a needle punch can be used. Examples thereof include non-woven fabrics produced by various manufacturing methods such as non-woven fabrics.

As shown in FIGS. 1 to 3, the leg edge portion LS forming the opening edges of each of the pair of leg openings LH and LH has leg elasticity for forming one or a plurality of thread-like or band-shaped leg gathers. The members 33 are arranged in an extended state, whereby a substantially continuous annular leg gather is formed at the opening edges of each of the pair of leg openings LH and LH. In the present embodiment, as shown in FIGS. 2 and 3, the leg elastic member 33 is located on the outer side in the lateral direction Y from the side edges 2S and 2S along the vertical direction X of the absorbent body 2 in the exterior body 3. It is arranged in a portion to be used and an arrangement region of the absorbent main body 2 in the exterior body 3 (a region overlapping the absorbent main body 2 in a plan view). However, in the arrangement region of the absorbent main body 2 in the exterior body 3 (the region overlapping the absorbent main body 2 in a plan view), the leg elastic member 33 is divided and the elasticity is hindered, and the elastic elasticity is impaired. Is not arranged in the state where is expressed.

Further, at least one of the front body 1F and the back body 1R, a plurality of elastic members 34, 35 arranged in an extended state in the lateral direction Y are intermittently arranged in the vertical direction X at the portion corresponding to the wearer's waist circumference. It is arranged. In the present embodiment, as shown in FIGS. 1 to 3, the ventral portion 1A, which is a portion corresponding to the waist circumference of the front body 1F, and the dorsal portion 1C, which is a portion corresponding to the waist circumference of the back body 1R. A plurality of thread-like or strip-shaped elastic members 34, 35 are arranged in both in an extended state in the lateral direction Y, and the plurality of elastic members 34, 35 are intermittently arranged at predetermined intervals in the vertical direction X.

Further explaining the portion of the diaper 1 corresponding to the waist circumference of the wearer, a plurality of waist elastic members 34 for forming waist gathers are laterally Y on the waist portion W1 in each of the ventral side portion A and the dorsal side portion C. It is arranged in an extended state. The waist elastic member 34 extends over substantially the entire length of the waist portion W1 in the lateral direction Y. The waist portion W1 is a portion of the exterior body 3 located around the waist of the wearer, and is usually located in the vertical direction X from the end of the ventral side A side or the dorsal side C side of the exterior body 3 in the vertical direction X. It is an area up to 1 to 15% of the total length. As described above, the waist elastic member 34 is arranged on the waist portion W1 in a state in which the elastic elasticity is exhibited, so that the opening edge portion of the waist opening portion WH is substantially continuous over the entire circumference thereof. An annular waist gather is formed.

Further, in the waist circumference portion W2 located between the waist portion W1 and the crotch lower portion 1B in each of the ventral side portion A and the dorsal side portion C, a plurality of waist circumference elastic members 35 for forming waist circumference gathers are laterally arranged. It is arranged in the extended state in the direction Y. In the present embodiment, as shown in FIGS. 2 and 3, the waistline elastic member 35 is located at least at a portion of the exterior body 3 located on the outer side of the lateral edges 2S and 2S of the absorbent body 2. Is arranged in an elongated state so as to exhibit elastic elasticity, but is divided in the arrangement region of the absorbent main body 2 in the exterior body 3 (the region overlapping with the absorbent main body 2 in a plan view). Therefore, the elasticity is inhibited, and it is not arranged in a state where elastic elasticity is exhibited.

Each of the above elastic members 33, 34, and 35 is sandwiched and fixed between the outer layer sheet 31 constituting the exterior body 3 and the inner layer sheet 32 by a joining means such as an adhesive. As the elastic members 33, 34, and 35, elastic materials such as natural rubber, polyurethane resin, urethane foam resin, and hot melt elastic member are formed into a thread-like (thread rubber) or band-like (flat rubber). It is preferably used.

As one of the main features of the diaper 1 of the present embodiment, as shown in FIGS. 1 and 2, a plurality of elastic members around the waist 35 arranged in the elastic member around the waist W2 are a white elastic member 350 and at least one. A type of non-white elastic member 351 is included, and the non-white elastic member 351 is arranged at a position overlapping the absorbent body 2 in the vertical direction X, and the vertical side edges 2S, 2S of the absorbent body 2 are arranged. The point is that the extended portion of the non-white elastic member 351 is made visible from the skin facing surface side, that is, the inner surface side (the surface sheet 21 and the inner layer sheet 32 side). Be done. In FIGS. 1 and 2, among the elastic members around the waistline 35 shown by the dotted lines, the relatively thin dotted line is the white elastic member 350, and the relatively thick dotted line is the non-white elastic member 351. The "position that overlaps with the absorbent body 2 in the vertical direction" here is "the same position as the absorbent body 2" (the position that overlaps with the absorbent body 2 in a plan view) and "outside the lateral direction Y of the absorbent body 2". Includes "position" (a position that does not overlap with the absorbent body 2 in a plan view). The non-white elastic member 351 exists at least in the "outer position of the absorbent body 2 in the lateral direction Y" in the form of an extending portion from the side edge 2S of the absorbent body 2.

As shown in FIGS. 1 and 2, in the present embodiment, a plurality (three) of non-white elastic members 351 are arranged on both the ventral side portion 1A and the dorsal side portion 1C, and all of them are absorbent. It extends outward in the lateral direction Y from both side edges 2S and 2S of the main body 2. Further, in the present embodiment, the non-white elastic member 351 is not arranged at the outer position of the absorbent body 2 in the vertical direction X. However, if at least one non-white elastic member 351 is arranged at a position overlapping the absorbent body 2 in the vertical direction X, the other non-white elastic member 351 is outside the vertical direction X of the absorbent body 2. It may be arranged in a position.

From the viewpoint of further enhancing the visibility of the non-white elastic member 351 from the side facing the skin of the diaper 1, a member arranged closer to the wearer's skin than the elastic member 351 and covering the elastic member 351 is carried out. In the form, it is preferable that the extending portions 31AE and 31CE of the inner layer sheet 32 and the outer layer sheet 31 have a light transmissive color and have a color different from the color of the elastic member 351. In this type of diaper, a white non-woven fabric is usually used as a sheet constituting the exterior body, but when the inner layer sheet 32 and the outer layer sheet 31 are white non-woven fabrics usually used in diapers, there is no particular problem in the inner layer sheet. The non-white elastic member 351 can be visually confirmed via 32.

As described above, in addition to the white elastic member 350 that is generally used as the waistline elastic member 35, the non-white elastic member 351 exists, and the non-white elastic member 351 is in the lateral direction Y from the absorbent body 2. Since the outward extending portion is visible from the skin facing surface side, the non-white elastic member 351 extending laterally Y when the absorption pad is attached to the skin facing surface side of the diaper 1. Since the extended portion of the absorption pad functions as a mark for alignment in the vertical direction X of the absorption pad, the positioning operation of the absorption pad can be performed smoothly. The effect of the combined use of the absorbent pad can be sufficiently obtained without causing inconvenience such as leakage. In particular, since the non-white elastic member 351 is visible from the skin facing surface side of the diaper 1, the wearer of the diaper 1 can smoothly wear the absorbent pad by himself / herself. That is, when the wearer of the diaper 1 wears the absorbent pad by himself / herself, usually, both feet are inserted into the leg openings LH and LH to raise the diaper 1 to the height of the knee, and the diaper 1 in that state is used. Positioning the inside of the diaper 1 by inserting the absorbent pad from the 1st floor side of the front body while visually checking the inside, that is, the side facing the skin (the surface sheet 2 side) through the waist opening WH in a state of being expanded with both feet. When performing the operation, since the wearer can visually confirm the non-white elastic member 351 through the waist opening WH in such a positioning operation, the absorption pad can be smoothly positioned by relying on the non-white elastic member 351. be able to.

Whether or not the non-white elastic member 351 is visible from the non-skin facing surface side, that is, the outer surface side (outer layer sheet 31 side) of the diaper 1 is not important in the present embodiment. As described above, the non-white elastic member 351 is used as a mark when the absorption pad is attached to the inner surface side while visually checking the inner surface side of the diaper 1, and is non-white from the outer surface side of the diaper 1. This is because even if the elastic member 351 cannot be visually confirmed, there is no problem in the operation of attaching the absorption pad. When the non-white elastic member 351 is visible from the outer surface side of the diaper 1, advantages such as improvement in the appearance of the diaper 1 can be achieved. In the case of a member arranged on the side farther from the wearer's skin than the non-white elastic member 351 and covering the elastic member 351; in the present embodiment, the outer layer sheet 31 is a white non-woven fabric normally used in a diaper. The elastic member 351 can be visually confirmed from the outside of the diaper 1 via the outer layer sheet 31.

Considering the improvement of the operability of the positioning operation when the diaper wearer himself wears the absorbent pad as described above, at least the part corresponding to the wearer's waist circumference (ventral part 1A) on the front body 1F. , It is preferable that a non-white elastic member 351 is arranged. When the wearer of the diaper 1 wears the absorbent pad by himself / herself, as described above, insert both feet into the leg openings LH and LH of the diaper 1 and wear the diaper 1 so as to stay below the crotch part of the wearer. The inside of the diaper is visually confirmed through the waist opening WH of the diaper 1 with the wearer facing down while being supported by both feet. This is because the part that is particularly easy to see is the front body 1F. The form in which the non-white elastic member 351 is arranged on only one of the front body 1F and the back body 1R has an advantage that the front-back direction of the diaper can be easily discriminated.

In the present embodiment, since the non-white elastic member 351 is arranged not only on the front body 1F but also on the back body 1R at the portion (dorsal side portion 1C) corresponding to the wearer's waist circumference, the back body Even in 1R, the absorption pad can be smoothly positioned by relying on the non-white elastic member 351. Generally, when the absorbent pad is worn by a third party (for example, the wearer's caregiver) instead of the wearer himself, the absorbent pad is supported by both feet of the wearer at a position below the crotch of the wearer. After that, the absorbent pad is often inserted into the diaper from the body side, and in that case, a non-white elastic member 351 is arranged on the back side 1C of the back body 1R as in the diaper 1 of the present embodiment. Then, the alignment in the vertical direction can be easily performed by using the non-white elastic member 351 as a mark.

In the front body 1F or the back body 1R, the non-white elastic members 351 extending outward in the lateral direction Y from the absorbent main body 2 (main body extension region 2V) may be of two or more types having different colors from each other. can. For example, in FIG. 2, three non-white elastic members 351 extending in the lateral direction Y are arranged on the ventral side portion 1A, but these three may not be the same color but different colors. Specifically, for example, green, blue, and red are in order from the side closest to the vertical center line Clx. By doing so, for example, when a plurality of types of absorption pads having different sizes (length X in the vertical direction) are used properly, an appropriate non-white elastic member 351 is selected according to the size of each absorption pad. However, the elastic member 351 of the selected color can be used for positioning the absorption pad, and can be used for various absorption pads.

Further, when the non-white elastic member 351 is arranged on both the front body 1F and the back body 1R as in the present embodiment, the color of the non-white elastic member 351 is arranged on the front body 1F and the back body 1R. May be different. "Colors are different" here means that when a plurality of non-white elastic members 351 are arranged on each of the front body 1F and the back body 1R, 1) all the non-white elastic members 1F and the back body 1R are arranged. Not only the forms in which the colors of the elastic members 351 of the above are different from each other, but also the forms in which only the colors of some non-white elastic members 351 are different from each other in the front body 1F and the back body 1R are included. In 1), for example, the plurality of non-white elastic members 351 on the front body 1F are all blue, and the plurality of non-white elastic members 351 on the back body 1R are all green. Three types of elastic members of red, blue, and green are arranged as non-white elastic members 351 on the 1st floor, and one type of blue elastic members are arranged as non-white elastic members 351 on the back body 1R. If the color of the non-white elastic member 351 is different between the front body 1F and the back body 1R, it becomes easier to discriminate the front-rear discrimination direction of the diaper, which may lead to improvement in the mounting operability of the absorption pad.

Further, the non-white elastic member 351 may be thicker than the white elastic member 350. As a result, the visual visibility of the non-white elastic member 351 is further enhanced, which may lead to an improvement in the mounting operability of the absorption pad. The color of the non-white elastic member 351 is not particularly limited, and may have a color-coded pattern consisting of two or more colors in addition to a single color such as red, blue, and green.

Although the present invention has been described above based on the preferred embodiment thereof, the present invention is not limited to the above embodiment. For example, in the above embodiment, the non-white elastic member 351 is arranged on both the front body 1F and the back body 1R, but even if it is arranged on only one of the front body 1F and the back body 1R. good. Further, in the above-described embodiment, the elastic member 35 (350,351) around the waist is divided in the arrangement region of the absorbent main body 2 to inhibit the elasticity, but such elasticity inhibition processing is performed. However, it may extend continuously in the lateral direction Y from one end to the other end of the exterior body 3 in the lateral direction Y, that is, over the pair of side seal portions S, S. Further, in the above-described embodiment, the outer layer sheet 31 and the inner layer sheet 32 constituting the exterior body 3 are each composed of one continuous sheet, but even if a plurality of sheets are combined and configured. good. Further, the exterior body 3 is divided into an exterior body ventral region located in the ventral portion 1A and an exterior body dorsal region located in the dorsal portion 1C, and the absorbent main body 2 is divided into the exterior body ventral region and the exterior body ventral region. It may be bridged and fixed to the dorsal region of the exterior body. Further, the absorbent article of the present invention is not limited to the pants-type disposable diaper, but broadly includes the article used for absorbing the liquid discharged from the human body, and also includes the deployable disposable diaper, the sanitary shorts and the like.
