Description

  The present invention relates to an absorbent pad (inner) that is used overlapping with a worn article (outer) such as an absorbent article.

  2. Description of the Related Art 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 on the skin facing surface of a worn article such as a disposable diaper. For example, a urine absorption pad, which is a type of absorption pad, is fixed on the surface sheet of a disposable diaper worn by adults (often elderly people) whose physical function is weakened or weakened by disease, and absorbs incontinence urine When used for holding, if the amount of excreted urine is relatively small, only the urine collection pad needs to be replaced, and the frequency of replacement of the disposable diaper can be reduced.

  Some absorbent pads are provided with a fastening material that is removably fastened to the skin-facing surface of the article to be worn. As this fastening material, there is one using a mechanical fastener. The mechanical fastener includes a so-called male member made of a hook material having a large number of hooks on the outer surface, and a so-called female member to which the male member is detachably attached, and a loop shape in which the female member has a hook of the male member. The male member is fixed to the female member so as to be hooked on the fiber or the non-woven fiber. The skin facing surface of an absorbent article such as a disposable diaper to which an absorbent pad is fastened is often formed of a nonwoven fabric, and the nonwoven fabric has a plurality of fibers that can be entangled with many loop-like fibers and hook materials. Therefore, by using a hook material (male member) as a fastening material for the absorbent pad, the absorbent pad is attached to the skin facing surface of the wearing article, for example, a nonwoven fabric surface sheet, through the hook material as the fastening material. It can be easily fixed.

  A typical absorbent pad includes a top sheet that forms a skin facing surface, a non-skin facing surface, that is, a back sheet that forms a facing surface of an absorbent article that is used in combination, and an absorbent body interposed between both sheets. The absorbent pad is fixed to the top sheet of the absorbent article at a predetermined location on the non-skin facing surface of the main body, that is, the outer surface of the back sheet, for example, in the vicinity of the longitudinal front and rear ends of the main body. Fastening materials are provided for this purpose. However, for example, in the case where a plurality of absorbent pads having such a configuration are exchanged for use with one absorbent article, the operation of peeling the absorbent pad fastening material from the surface sheet of the absorbent article is performed each time the exchange pad is used. Since this is done, the topsheet may be damaged and its constituent fibers may become fluffy. When such an absorbent article with a fuzzy surface sheet is used without an absorbent pad as usual, it may irritate the wearer's skin, which may reduce the feeling of wearing, In addition, the water-absorbing polymer encapsulated by the tearing of the surface sheet may leak out.

  On the other hand, Patent Document 1 describes an absorbent pad in which a fastening material is disposed in a portion other than the main body. That is, in the absorbent pad described in Patent Document 1, the front and back sheets constituting the main body extend outward in the width direction from both side edges along the main body longitudinal direction to form a pair of left and right flaps, and the main body longitudinal length of each flap A fastening material is arranged on the outer surface on the back sheet side in the center in the direction. When fastening the absorbent pad described in Patent Document 1 to an absorbent article such as a disposable diaper, as shown in FIG. It is fastened to a flap located outward in the width direction of the absorbent body, and is not fastened on the absorbent body of the absorbent article like a conventional typical absorbent pad.

  Patent Document 2 describes a vertically long absorbent pad having wings on both sides in the longitudinal direction, and a fastening material made of a pressure-sensitive adhesive layer is disposed on the wing. When the absorbent pad described in Patent Document 2 is fixed to an absorbent article such as a disposable diaper, the absorbent pad is placed on one surface of the absorbent article as shown in FIG. In this state, the wing extending from the side edge of the absorbent article is folded back to the other side of the absorbent article, and the fastening material disposed on the wing is placed on the other side of the absorbent article. Fasten. In Patent Document 2, as a variation of this wing, a pair of arrangements in the longitudinal center of both side edges of the absorbent pad (FIG. 3 of the same document 2) and the longitudinal direction of both side edges of the absorbent pad are omitted. The form (FIG. 9 of the said literature 2) in which several pairs are distribute | arranged and arranged without spacing over the full length is described concretely.

  As shown in FIG. 3, the absorbent pad 1 of the present embodiment can be used by being fastened to a skin facing surface side of a disposable diaper 100 as a separate absorbent article via a fastening material 60. The disposable diaper 100 used in combination with the absorbent pad 1 has the same configuration as a typical disposable diaper, a liquid-permeable surface sheet 101 that forms a skin-facing surface, and a liquid that forms a non-skin-facing surface. It has a permeable back sheet 102 and an absorbent body 103 interposed between both sheets 101 and 102 and is long in one direction in the expanded state in the same manner as the absorbent pad 1. A pair of leak-proof cuffs 104 and 104 are provided on both sides of the disposable diaper 100 on the skin facing side, and a pair of leg flap portions having an elastic member on the outer side in the lateral direction Y of the absorbent body 103. 107 and 107 are provided. The leak-proof cuff 104 of the diaper 100 has the same configuration as the leak-proof cuff 7 of the absorbent pad 1, and one leak-proof cuff forming sheet 105 continuous over the entire length in the longitudinal direction X of the diaper 100. And one or a plurality of (two in this embodiment) thread-like leakproof cuff forming elastic members 106 fixed to the sheet 105 in a stretched state, corresponding to the wearer's front-rear direction. It is continuous in the vertical direction.

  When the absorbent pad 1 according to the present embodiment is fixed to the diaper 100, the fixing material 60 arranged in the fixing portions 6F and 6R is fixed to the leak-proof cuff 104 of the diaper 100 as shown in FIG. To wear. Although only the front side fastening part 6F is shown in FIG. 3, the rear side fastening part 6R is also fastened to the leak-proof cuff 104 of the diaper 100 in the same manner as the front side fastening part 6F. That is, the fastening portions 6F and 6R of the absorbent pad 1 are respectively bent on the non-skin facing surface side of the main body 5, that is, the back sheet 3 side, and arranged on the back sheet 3 side in the folded fastening portions 6F and 6R. The outer surface of the portion (standable portion) that stands up toward the wearer's skin when wearing the fastening material 60 on the leak-proof cuff 104 of the diaper 100, more specifically, the elastic member 106 for forming the leak-proof cuff. It is pressed against the outer surface of the arrangement part of and fixed. In this way, the absorbent pad 1 is not intended to be used by being fastened to a forming member at a site that directly contacts the wearer's skin, such as a surface sheet of an absorbent article to be used together, like a conventional absorbent pad. Therefore, the damage given to the wearing article used together is reduced, and the inconvenience resulting from such damage, for example, a decrease in wearing feeling and leakage of the water-absorbing polymer can be effectively prevented.

  Moreover, according to the absorption pad 1, the fastening operation of the fastening material 60 can be performed easily and reliably. That is, in order to fix the fastening material 60 to the leak-proof cuff 104 of the diaper 100, the fastening parts 6F and 6R and the stand-up possible part of the leak-proof cuff 104 (arrangement part of the elastic member 106) are made to correspond. In the absorbent pad 1, the front fastening part 6F and the rear fastening part 6R are spaced apart in the vertical direction X, where it is necessary to firmly grip them with fingers from the front and back in the longitudinal direction X. Since the fastening portions 6F and 6R are easily operated independently, it is easy to perform gripping with such a finger, and thus the fastening operation of the fastening material 60 can be easily and reliably performed.

  From the viewpoint of further improving the ease and certainty of the fastening operation of the absorbent pad 1 to the worn article, the separation length between the front fastening part 6F and the rear fastening part 6R, that is, the front fastening part 6F. The distance between the inner root 6F1 in the vertical direction X and the inner root 6R1 (see FIG. 1) in the vertical direction X of the rear fastening portion 6R is at least that of each fastening portion 6F, 6R. A range that can secure a space that can be gripped by human fingers from the front and back in the longitudinal direction X is necessary. Specifically, it is preferably 50 mm or more, more preferably 80 mm or more, and preferably 300 mm or less. Is 260 mm or less, more specifically, preferably 100 mm or more and 240 mm or less, and more preferably 120 mm or more and 200 mm or less. In the absorbent pad 1 of the present embodiment, as described above, such a separation length is equal to the total length in the longitudinal direction X of the crotch part 1M.

  In the absorbent pad 1 of the present embodiment, as shown in FIG. 1, from the viewpoint of the ease of the fastening operation to the worn article, the edge part (fastening) of the fastening parts 6 </ b> F and 6 </ b> R opposite to the main body 5. (Extension direction front-end | tip part 61) 61 of the parts 6F and 6R is made in parallel with the vertical centerline which divides the wearing article used together with the absorption pad 1 like the diaper 100 in the horizontal direction, and extends in the vertical direction. Such a configuration is adopted in consideration of the shape in plan view of a fixing portion (not shown) that becomes a starting point when the leak-proof cuff 104 of the diaper 100 stands. The basic configuration of the diaper 100 is the same as that of the absorbent pad 1, and the vertical center line (not shown) in the diaper 100 corresponds to the vertical center line Lx of the absorbent pad 1 shown in FIG. The fixed part has a continuous linear shape parallel to the longitudinal center line Lx, like the fixed part 72 of the absorbent pad 1.

  When the fastening portions 6F and 6R are fastened to the leak-proof cuff 104, the edge portion 61 of the fastening portions 6F and 6R is usually a fixing portion (not shown) that serves as a starting point of the leak-proof cuff 104 (fixing of the absorbent pad 1). As described above, the edge portion 61 is made parallel to the vertical center line (the imaginary line corresponding to the vertical center line Lx of the absorbent pad 1), as described above. In combination with the fact that the front side fastening part 6F and the rear side fastening part 6R are separated from each other in the longitudinal direction X, the leak-proof cuff 104 of the fastening parts 6F, 6R (which is a standable part). The ease of the fastening operation to the arrangement portion of the elastic member 106, and the certainty can be further improved.

  In particular, when the diaper 100 is a so-called pants-type disposable diaper (pants-type wearing article) having a waist opening and a leg opening, the fastening operation of the fastening material 60 to the leak-proof cuff 104 can be performed more smoothly. Is possible. That is, when the absorbent pad 1 is fixed to the pants-type disposable diaper 100, first, the operation of mounting the diaper 100 is performed in the usual manner, and in the middle of the operation, specifically, for example, a pair of legs of the diaper 100 The absorbent pad 1 may be fastened to the diaper 100 while the diaper 100 is pulled up to the crotch side with both the legs of the wearer inserted in the opening. However, even if it is not a complete standing state, it is in the standing state, so that the fastening operation of the fastening material 60 to the leak-proof cuff 104 can be performed smoothly. That is, it can be said that the absorbent pad 1 is particularly effective when used in combination with a pants-type wearing article having a waist opening and a leg opening.

  When the fastening material 60 of the fastening parts 6F and 6R is fastened to the standable part (arrangement part of the elastic member 106) of the leak-proof cuff 104, the elastic member 106 arranged in the stretched state in the leak-proof cuff 104 is a diaper. When the standable part stands up by contracting in the wearing state of 100 or the like, the entire absorbent pad 1, that is, a continuous part extending from the abdominal side part 1F to the back side part 1R is pushed up by the standable part. FIG. 3 is a diagram schematically showing the pushing-up of the absorbent pad 1 by the leak-proof cuff 104 of the diaper 100. The absorbent pad 1 pushed up by the leak-proof cuff 104 and the skin facing surface of the diaper 100, that is, the surface sheet 101. As shown in FIG. 3, a space can be formed between the two. However, FIG. 3 is drawn schematically from the viewpoint of easy explanation, and the space as shown in FIG. 3 is not necessarily formed between the absorbent pad 1 and the skin facing surface of the diaper 100. .

  As described above, when the absorbent pad 1 is used in combination with the diaper 100, the absorbent pad 1 is pushed up by the contraction force of the elastic member 106 constituting the leak-proof cuff 104 of the diaper 100. Therefore, as shown in FIG. When the diaper 100 to which is fixed is worn as usual, as shown in FIG. 4, the absorbent pad 1 can be pushed up to the crotch side of the wearer and can be in close contact with the wearer's skin. And since the absorption pad 1 adheres to a wearer's skin in this way, it is hard to produce the shift | offset | difference from the appropriate position of the absorption pad 1 in wear, the absorption performance which the absorption pad 1 originally has is fully exhibited, and favorable A comfortable feeling can be obtained.

  In particular, in the absorbent pad 1, as described above, the fastening material 60 does not overlap the absorbent body 4 in the thickness direction when the absorbent pad 1 is expanded and stretched as shown in FIG. The fastening portions 6F and 6R that are present are soft. For this reason, the fastening portions 6F and 6R are easy to bend after being fastened to the worn article. Therefore, the followability of the absorbent pad 1 to the wearer's body is enhanced. There is little good wearing feeling.

  FIG. 5 shows an absorbent pad 1A that is another embodiment of the absorbent pad of the present invention. In the absorbent pad 1 shown in FIG. 1, the number of fastening portions 6F and 6R arranged on one end side (front portion 1F) and the other end side (rear portion 1R) in the longitudinal direction X is a pair. In the absorbent pad 1A, as shown in FIG. 5, there are a plurality of pairs, specifically two pairs. In addition, about the absorption pad 1A, the different structure part from the absorption pad 1 is mainly demonstrated, the same code | symbol is attached | subjected to the same structure part, and description is abbreviate | omitted. The description of the absorbent pad 1 is applied as appropriate to components that are not specifically described with respect to the absorbent pad 1A.

  In the absorbent pad 1A, as shown in FIG. 5, in the front portion 1F, the two fastening portions 6F and 6F adjacent in the vertical direction X are separated in the vertical direction X, and also in the rear portion 1R. The two fastening portions 6R, 6R adjacent to each other in the vertical direction X are separated from each other in the vertical direction X. As for the separation length of the “two fastening portions adjacent to each other in the vertical direction”, as described for the absorbent pad 1, the ease and certainty of the fastening operation of the absorbent pad 1A to the wearing article are further improved. In view of the above, a range that can secure a space in which the fastening portions 6F and 6R can be gripped by human fingers from the front and back in the longitudinal direction X is preferable, and specifically as described above. The same effect as that of the absorbent pad 1 can be obtained by the absorbent pad 1A. In particular, the absorbent pad 1A has a larger number of the fastening portions 6F and 6R than the absorbent pad 1, so that it can be firmly attached to the worn article, and the inconvenience of shifting from an appropriate position during wearing can be further reduced. obtain.

In the absorbent pad 1A, the “separation length between the front side fastening portion 6F and the rear side fastening portion 6R” in the above-described absorbent pad 1, that is, “the inner side in the longitudinal direction X of the front side fastening portion 6F”. The length corresponding to the “separation length between the root 6F1 and the inner root 6R1 in the longitudinal direction X of the rear fastening portion 6R” is a plurality (two in the illustrated form) of the front fastening portions 6F. The base 6F1 on the inner side in the longitudinal direction X of the front side fastening portion 6F located on the innermost side in the vertical direction and the innermost side in the longitudinal direction among the plurality (two in the illustrated form) of the rear side fastening portions 6F This is the distance from the inner base 6F1 in the longitudinal direction X of the rear fastening portion 6F located on the side.

Although the present invention has been described above, the present invention is not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit of the present invention. For example, the shape, the number of arrangement, the arrangement position, and the like of the fastening portions 6F and 6R are not limited to the above-described embodiment, and can be adjusted as appropriate.
Moreover, in the said embodiment, the fastening material 60 is distribute | arranged to the same surface side as the non-skin opposing surface side of the main body 5 in the expansion | deployment state of the absorption pad 1 in the fastening parts 6F and 6R (refer FIG. 1). However, it may be arranged on the opposite side, that is, on the same side as the skin facing surface side of the main body 5 (on the top sheet 2 side) in the same state. In that case, in the case where the fastening material 60 is fastened to the standable portion (arrangement portion of the elastic member 106) of the leak-proof cuff 104 of the diaper 100 as shown in FIG. 3, the top sheet at the fastening portions 6F and 6R. The fixing material 60 disposed on the second side may be pressed against the inner side surface of the standable portion (the side opposite to the side on which the fixing material 60 is fixed in FIG. 3) to be fixed.

  The absorbent pad of the present invention can be worn together with various wearing articles, and the wearing articles that can be used in combination include disposable diapers (including both a pants-type and a so-called unfolded type having a fastening tape) as shown in FIG. Various absorbent articles such as light incontinence shorts and light incontinence pants, as well as clothing shorts and underwear / underwear.
