Tape type disposable diaper

  The present invention relates to a tape-type disposable diaper.

  A general tape-type disposable diaper includes a ventral part extending from the center in the front-rear direction to the front side, a back side part extending to the rear side, a fastening tape protruding from both side edges of the back side part, and a ventral side. A target tape provided on the outer surface of the portion, and when being attached to the body, the fastening tape is rotated from the left and right sides to the ventral side and is detachably connected to the outer surface of the target tape (for example, Patent Documents) 1 and 2).

  In such a tape-type disposable diaper, the fastening tape needs to have a sufficiently high peel strength with respect to the target tape so that the fastening tape does not come off from the target tape during mounting. It is desirable that the fastening tape be easily detached from the target tape when the position is appropriately adjusted or when the diaper is discarded.

  However, with conventional general tape-type disposable diapers, it is necessary to pinch the tip of the fastening tape with a finger and peel it off, and it can be easily removed for users with weak grip strength or users who are hard to bend their fingers. It was not a thing.

As the absorbent body 3, it is possible to use a laminate of pulp fibers, an aggregate of filaments such as cellulose acetate, or a nonwoven fabric, and a mixture obtained by mixing and fixing a superabsorbent polymer as necessary. . Although the illustrated absorber 3 has a single layer structure, it may have a two-layer structure including a lower layer absorber and an upper layer absorber stacked thereon. Moreover, the absorber 3 can be wrapped with crepe paper (not shown) as needed. Moreover, the shape of the absorber 3 can be determined as appropriate, but in addition to the hourglass shape as illustrated, a shape that extends from the front side to the rear side of the crotch portion, such as a rectangle, is preferable. It is desirable that the basis weight of the absorbent body 3 is about 100 to 500 g / m ² and the thickness is about 1 to 15 mm. The basis weight of the highly water-absorbent resin is preferably about 0 to 300 g / m ² . If the content of the superabsorbent resin is too small, sufficient absorbability cannot be provided, and if it is too large, the entanglement between the pulp fibers is lost, and twisting or cracking is likely to occur.

(Liquid impervious sheet)
The liquid-impermeable sheet 1 extends outward from the periphery of the absorber 3 and blocks movement of excrement absorbed by the absorber 3 to the back side. As the liquid-impermeable sheet 1, in addition to a plastic film such as a polyethylene film, a sheet having moisture permeability can be used without impairing water shielding from the viewpoint of preventing stuffiness. This water-impervious and moisture-permeable sheet is a microporous sheet obtained by, for example, melt-kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene to form a sheet, and then stretching in a uniaxial or biaxial direction. Can be used. The weight per unit area of the liquid-impermeable sheet 1 is preferably 13 to 40 g / m ² , and the thickness is preferably 0.01 to 0.1 mm.

  In order to make the outer surface of the diaper look and feel like cloth, the entire back surface of the liquid-impermeable sheet 1 is covered with an exterior sheet 12, and the outer peripheral edges of both sheets 1 and 12 extend to the outer peripheral edge of the diaper. Yes. Although various nonwoven fabrics can be used as the exterior sheet 12, a spunbond nonwoven fabric is preferable. The exterior sheet 12 can be omitted.

As shown in FIGS. 3 to 5, on both sides of the inner surface of the article (in the illustrated form, the surface of the liquid-impermeable sheet 1 extending from the surface of the side edge 54 a of the top sheet 2 to the side) A root portion 4x on the outer side in the width direction WD of the leg-surrounding three-dimensional gather 4 sheet 4s constituting the leg-surrounding three-dimensional gather 4 is attached to the entire front-rear direction LD. As the leg gathered three-dimensional gather 4 sheet 4s, various non-woven fabrics (spunbond non-woven fabrics are suitable), plastic films similar to those used for the liquid-impermeable sheet 1, or a laminate sheet thereof can be used. A nonwoven fabric subjected to a water repellent treatment is preferable in terms of touch to the skin. The protruding portion 4c on the center side in the width direction WD of the three-dimensional gather 4 sheet 4s around the legs is fixed to the inner surface of the article (in the illustrated form, the surface of the top sheet 2) with hot melt adhesive or the like in a lying state at both ends in the front-rear direction LD. The intermediate portion between these is an unfixed free portion 4f, and the free portion 4f has a tip portion or the like (an end portion on the center side in the width direction WD in the unfolded state). Is fixed with a hot melt adhesive or the like in a state where the elongated elastic elastic member 4G extends along the front-rear direction LD. In the illustrated example, a plurality of the elongated elastic elastic members 4G are provided with a predetermined interval, but one may be used. The elongated elastic elastic member 4G (same for other elongated elastic elastic members) includes natural rubber or synthetic rubber formed into a thread shape, string shape, belt shape, etc., specifically, styrene rubber, olefin rubber, urethane. Commonly used materials such as rubber, ester rubber, polyurethane, polyethylene, polystyrene, styrene butadiene, silicone , and polyester can be used. As shown in FIG. 4, as a result of the contraction force of the elongated elastic elastic member 4G acting on the free portion 4f, the leg-shaped three-dimensional gathers 4 standing on the inner surface of the article (the top sheet 2 surface in the illustrated embodiment) Configure. The base end 4b of the standing part is located at the boundary between the fixed part 4x on the outer side in the width direction and the inner part 4c in the leg-around three-dimensional gather 4.

  At the front and rear direction both ends of the disposable diaper, the liquid impermeable sheet 1, the exterior sheet 12, the liquid permeable top sheet 2 and the leg-around three-dimensional gather sheet 4s are respectively extended on the front and rear sides than the front and rear ends of the absorbent body 3, An end flap portion EF in which the absorber 3 does not exist is formed. On the other hand, the liquid-impermeable sheet 1, the exterior sheet 12, the liquid-permeable top sheet 2, and the leg-around three-dimensional gather sheet 4 s extend from the side edges of the absorbent body 3 on the left and right sides of the disposable diaper. A side flap portion SF in which the absorber 3 does not exist is formed. Of the side flap portion SF, the portions located in the waist portion of the ventral portion F and the waist portion of the dorsal portion B are extended laterally from the intermediate portion therebetween, and these portions However, the middle part of the diaper becomes the surrounding part of the leg, and the side edges thereof become the edges Le of the leg openings.

(Plane gathering)
An elongated elastic member 7 is fixed between the liquid impervious sheet 1 and the exterior sheet 12 with a hot melt adhesive or the like in the stretched state along the front-rear direction at the middle part in the front-rear direction of the side flap part SF. The so-called planar gathers are formed in the side flap portion SF by the contraction of the elongated elastic member 7. By this flat gather, the side part of the diaper is elastically stretched to fit around the leg.

The number of the elongated elastic members 7 on each of the left and right sides can be appropriately determined, but about 1 to 10, more preferably about 3 to 8, is appropriate. It is preferable to be about 15 mm, especially about 6-10 mm. Each of the elongated elastic members 7 includes a styrenic rubber, an olefinic rubber, a urethane rubber, an ester rubber, polyurethane, polyethylene, polystyrene, styrene butadiene, silicone , Normally used materials such as polyester can be used, and the thickness is preferably about 500 to 1500 dtex, and in the case of natural rubber, about 0.1 to 3 mm, particularly about 0.5 to 3 mm is preferable. Moreover, it is preferable that the elongation rate at the time of fixation of each elongate elastic member 7 is about 150 to 250%.

(Fastening tape)
A fastening tape 5 protruding from the side edge is attached to the side flap portion SF of the back side portion B, and a target tape 6 is adhered to the surface of the waist portion of the abdominal side portion F along the width direction. When the diaper 100 is applied to the body, the fastening tape 5 on both sides is rotated from the left and right sides to the ventral side and connected to the target tape 6 when the diaper 100 is applied to the body.

  As shown in FIG. 3, the fastening tape 5 includes a fixing portion 5 f fixed between the sheets in the waist side flap portion SF of the back portion B by means such as hot melt adhesive, and the side flap portion SF side. The protrusion 5e protrudes outward in the width direction from between the sheets on the edge, and the protrusion 5e has a distal end 5p and a main body 5b on the proximal side of the distal end 5p. . On the inner surface side (the top sheet 2 side) of the front end portion 5p of the fastening tape 5, as a connecting means 9 for detachably connecting to the target tape 6, a hook material (mechanical fastener (surface The male material) of the fastener) is attached, but an adhesive layer can be used instead of the hook material.

  Further, as shown in FIG. 5, the fastening tape 5 is provided with a perforation 10 extending in the width direction from the outer edge in the width direction of the intermediate portion in the front-rear direction to the inside of the main body portion 5 b, and the perforation 10 is cut off. Thus, as shown in FIG. 6, each can be separated into an upper step portion 5W and a lower step portion 5U each having a fixing portion, a main body portion, a tip portion, and a fixing portion. Instead of the perforation 10, it may be separated by cutting or the like in advance. As shown in FIG. 6, such a fastening tape 5 can be detachably connected to the target tape 6 of the ventral portion F in a state where the upper step portion 5W and the lower step portion 5U are crossed. Of course, the present invention is not limited to the upper and lower two-stage division type, and can be applied to other known fastening tapes such as a type that does not divide into two stages.

(Target tape)
The target tape 6 is intended to make it easy to attach and detach the fastening tape 5, and when the connecting means 9 of the fastening tape 5 is formed of a hook material, the hook-shaped protrusion is detachably hooked. A sheet material having a surface that can be used, for example, a female material or a nonwoven fabric of a mechanical fastener (surface fastener), and when a pressure-sensitive adhesive layer is used instead of a hook material, a resin sheet that can sufficiently exhibit its adhesiveness is used. Can be used. Although the dimension of the target tape 6 is not particularly limited, it is preferably about 60 to 90% of the maximum width of the ventral part. Further, when the connecting means 9 of the fastening tape 5 is a hook material of a mechanical fastener and the outer surface of the ventral portion F is formed of a nonwoven fabric, the target tape 6 is omitted and the hook material of the fastening tape 5 is used. It can also be directly connected to the nonwoven fabric on the outer surface of the ventral portion F.

(Finger insertion part / opening)
As shown in an enlarged view in FIG. 5, in the fastening tape 5, the connection force to the ventral part F is weaker than the connection part 51 in the connection region 50 that is the width direction WD range having the connection part 51 to the ventral part F. Or a finger insertion portion 52 that is not connected to the ventral portion F. The connection region 50 has a distal end edge 50 a located on the distal end side of the fastening tape 5 and a proximal end edge 50 b located on the proximal end side of the fastening tape 5, and the finger insertion portion 52 is a proximal end edge of the connection region 50. It continues from 50b to the tip edge 50a. Further, the connecting portions 51 are provided at least on both the front and rear sides of the finger insertion portion 52 in the connecting region 50.

  The finger insertion part 52 is not specifically limited as long as the connection force with respect to the ventral part F is weaker than the connection part 51, or is not connected with the ventral part F. Therefore, for example, as shown in FIG. 11 (a), the connecting means 9 is provided with an interval in the front-rear direction LD, and a portion between the connecting means 9 is used as a finger insertion portion 52, as well as in FIG. As shown, a connecting means 9 having a connecting surface can be provided over both front and rear sides of the finger insertion portion 52 to weaken or lose the connecting force in the front-rear direction LD of the connecting surface. Further, as the latter technique, as shown in FIG. 11B, for example, as shown in FIG. 5 and the like, in addition to a technique of subjecting the connecting means 9 itself to partial processing such as melting and crushing the pin of the hook material. As described above, a method of partially covering the connecting surface with the cover piece 53 can also be employed. In the form of the cover piece 53, the portion of the connecting surface of the connecting means 9 that is covered with the cover piece 53 becomes the finger insertion portion 52, and the portion of the connecting surface of the connecting means 9 that is not covered with the cover piece 53 is the connecting portion. 51. The cover piece 53 and the connecting surface of the connecting means 9 may be connected by a separate adhesive or welding, but it is preferable to use the connecting function of the connecting means 9. For this reason, it is preferable that the cover piece 53 is a material which can be attached and detached by the connection function of the connection means 9, and it is preferable that it is a nonwoven fabric in normal cases. If it is a nonwoven fabric, even if the connection means 9 is a hook material or an adhesive, it can connect, without preparing an additional means.

  In addition, as shown in FIG. 5 and the like, in the present tape-type disposable diaper, an opening 54 penetrating the front and back is provided on the center side in the width direction from the connecting portion 51 in a state where the fastening tape 5 is unfolded. Instead of the opening 54, a perforation for forming the opening 54 may be formed at the periphery of the portion that becomes the opening 54. The opening 54 is desirably provided in the fastening tape 5, but may be provided in the side flap portion of the back portion B depending on the position of the connection region 50 in the fastening tape 5.

  As shown in FIGS. 7A and 8, when the fastening tape 5 is peeled from the state in which the connecting portion 51 of the fastening tape 5 is connected to the outer surface of the ventral portion F, the inside of the fastening tape 5 is opened from the opening 54. When the finger 60 is introduced into the finger 60, the finger 60 is inserted into the finger insertion portion 52, and the fastening tape 5 is pinched by the inserted finger 60, the connecting portion 51 can be peeled without pinching the fastening tape 5. . Therefore, the fastening tape 5 can be easily removed even if the user has a weak gripping force or the user whose finger 60 is difficult to bend. In particular, as shown in FIG. 8, when the finger insertion portion 52 is formed by covering the connection surface of the connection means 9 with the cover piece 53, the connection means 9 of the finger insertion portion 52 is covered with the cover piece 53. Even if the finger 60 is inserted into the insertion portion 52, the skin is damaged (when the connecting means 9 is a hook material of a mechanical fastener), or the finger 60 cannot be inserted smoothly (when the connecting means 9 is an adhesive). It is prevented.

  In order to realize such a peeling function, it is necessary to form the finger insertion part 52 and the connection part 51 and the formation of the opening 54. However, when these are performed individually, it is preferable in terms of manufacturing complexity. Absent. Therefore, as shown in FIGS. 3 and 5, while the basic structure is that the finger insertion portion 52 is formed by partially covering the connecting means 9 with the cover piece 53, FIGS. 9B and 10B. ), The first portion located on the side having the connecting region 50 has the opening 54 so that the connecting portion 9 is hidden inside with the edge 54a of the opening 54 on the connecting region 50 side as the folding position. The cover piece 53 is folded back on the second portion located on the side, and has a peripheral shape that fits in the opening 54, and the edge 54 a on the connection region 50 side of the opening 54 on the connection surface of the connection means 9. A form in which the cover piece 53 is connected to the connecting means 9 is proposed.

  In this case, in the folded state in which the first portion is folded back onto the second portion, the cover piece 53 overlaps the opening 54 in a state of being connected to the connecting surface of the connecting means 9, and the first portion is folded. When unfolded from the state, as shown in FIGS. 5 and 8, the cover piece 53 connected to the connection surface of the first portion is folded back with the edge portion 54 a on the connection region 50 side in the opening 54 being folded, Opening 54 opens. Further, a cover piece 53 is connected to the connection surface of the connection means 9, and a portion covered with the cover piece 53 on the connection surface of the connection means 9 becomes a finger insertion portion 52.

  Therefore, for example, as shown in FIG. 9A and FIG. 10A, after the portion where the opening 54 is formed is separated from the periphery leaving the edge portion 54a on the connection region 50 side, the connection region 50 side of the opening 54 is removed. As shown in FIGS. 9B and 10B, the first portion on the side having the connection region 50 is folded back onto the second portion on the side having the opening 54, with the edge portion 54a being the folding position. The opening 54 and the cover piece 53 (that is, the finger insertion part 52 and the connecting part 51, and the opening 54) can be formed simultaneously by simply connecting the part surrounded by the separating part to the connecting surface of the connecting means 9, and easily And it can manufacture efficiently. In particular, in the manufacture of a general tape-type disposable diaper, each fastening tape 5 is formed by cutting, and after the fastening tape 5 is attached to a target member, the fastening tape 5 is folded to the center side in the width direction WD. Has been done. Therefore, in such a manufacturing method, the cover piece 53 is automatically formed when the fastening tape 5 is folded only by making a cut around the portion that becomes the opening 54 at the time of cutting the individual fastening tape 5. A finger insertion part 52 is formed by being connected to the connection surface, and as shown in FIGS. 9C and 10C, when the fastening tape 5 is unfolded in use, the opening 54 automatically opens. . In addition, similarly to a general tape type disposable diaper, it can be further folded and packed into a product packaging bag from the state shown in FIG. 9B and FIG. 10B.

  In this case, it is preferable that the cover piece 53 has the same shape as the opening 54 as shown in the figure because a portion that becomes a waste material (trim) is not generated by excision, but the first portion is folded back onto the second portion. As long as the cover piece 53 has a peripheral shape that fits in the opening 54 in the folded state, it may have a shape different from the opening 54.

  Further, in this embodiment, the width direction dimension of the cover piece 53 can be determined as appropriate, but the width direction WD dimension of the cover piece 53 needs to be longer than the shortest distance between the opening 54 and the connection region 50. . Further, in this embodiment, the distance in the width direction WD from the folding position (edge 54 a) to the tip of the fastening tape 5 is D, and the distance in the width direction WD from the folding position (edge 54 a) to the tip of the cover piece 53. When C is C, as shown in FIG. 8A, if D ≧ C, especially D> C, the cover piece 53 does not protrude from the tip of the fastening tape 5 as shown in FIG. It will be excellent. On the other hand, as shown in FIG. 8B, when C> D, the cover piece 53 protrudes from the tip of the fastening tape 5, but the finger insertion portion 52 continues in the width direction WD, and the fastening is performed. There is an advantage that the finger 60 can be inserted also from the front end side of the tape 5 to separate the connecting portion 51 and the insertion position can be visually recognized. Further, the connecting piece 51 of the fastening tape 5 can be peeled off by pinching the cover piece 53 protruding from the tip of the fastening tape 5.

(Finger insertion part shape)
As shown in FIG. 12A, the finger insertion part 52 inserts the finger 60 from the front end side of the fastening tape 5 when it continues from the base end edge 50 b of the connection region 50 to the front end edge 50 a. Since the connection part 51 can be peeled off and the finger insertion part 52 is continuous in the width direction WD, the finger 60 can be easily inserted from one side of the connection region 50 to the other side (first form). Further, as shown in FIG. 13B, when the finger insertion part 52 has a continuous portion from the proximal end edge of the connection region 50 to at least one edge in the front-rear direction LD of the connection region 50, The connection part 51 can be peeled by inserting the finger 60 from the front-rear direction LD of the tape 5 (second form).

  The shape of the finger insertion part 52 can be an appropriate shape such as a rectangle. For example, in the first embodiment, the connecting means 9 is continuous across the front and rear sides of the finger insertion part 52 in the connection region 50. 12A, the finger insertion part 52 has a shape in which the length in the front-rear direction LD becomes longer toward the proximal end side of the fastening tape 5. It is. In this embodiment, since the length of the finger insertion portion 52 in the front-rear direction LD is wide on the opening 54 side, the finger 60 can be easily inserted into the finger insertion portion 52 through the opening 54, but on the opposite side. Since the length of the finger insertion portion 52 in the front-rear direction LD is reduced and the length of the connection surface in the front-rear direction LD is increased accordingly, the connection force is reduced due to the provision of the finger insertion portion 52 (particularly the fastening). (At the front end side of the tape 5).

  Further, for example, in the first embodiment, when the connecting means 9 is continuous over both front and rear sides of the finger insertion portion 52 in the connection region 50, as shown in FIG. The length of the front-rear direction LD may increase as it goes toward the front end side of the fastening tape 5. In this case, since the length of the finger insertion portion 52 in the front-rear direction LD is wider on the distal end side, the finger 60 can be easily inserted from the distal end side, but on the opposite side, the front-rear direction LD of the finger insertion portion 52 is increased. And the length of the connecting surface in the front-rear direction LD is increased accordingly, so that the connection force is reduced due to the provision of the finger insertion portion 52 (particularly on the proximal end side of the fastening tape 5). Can be suppressed.

  Further, for example, in the first embodiment, when the connecting means 9 is continuous across both front and rear sides of the finger insertion portion 52 in the connection region 50, as shown in FIG. Is a preferable embodiment that has a shape in which the length of the front-rear direction LD increases from the intermediate position of the connecting region 50 in the width direction WD toward both sides of the width direction WD. That is, in this embodiment, since the length of the finger insertion portion 52 in the front-rear direction LD is wide on the opening 54 side and the distal end side of the fastening tape 5, it is easy to insert the finger 60 into the finger insertion portion 52 through the opening 54. However, in the middle of the width direction WD, the length of the finger insertion portion 52 in the front-rear direction LD becomes narrower, and accordingly, the length of the connecting surface in the front-rear direction LD increases, so the finger insertion portion 52 is provided. It is possible to suppress a decrease in the coupling force due to.

  Further, for example, in the second embodiment, when the connecting means 9 is continuous across both front and rear sides of the finger insertion portion 52 in the connection region 50, as shown in FIG. Can be configured to extend in an oblique direction from either one of the front and rear edges of the connecting means 9 toward the base edge 50 b of the connecting region 50. In this embodiment, the finger 60 can be inserted also from the front-rear direction LD of the fastening tape 5 to peel off the connecting portion 51, and the finger inserting portion 52 continues in an oblique direction. It can be easily inserted from one side of the direction to the other side.

  What is necessary is just to determine the dimension of the finger insertion part 52 suitably. For example, in the case of the first embodiment, the front-rear dimension of the finger insertion portion 52 is preferably about 15 to 60% of the front-rear dimension of the connection region 50. However, when the finger insertion part 52 is reasonably narrow, the part close to the finger insertion part 52 of the connecting part 51 of the fastening tape 5 is automatically peeled off simply by inserting the finger 60 into the finger insertion part 52. It becomes easy to completely peel off. Further, in the case where the connecting means 9 is continuous across the front and rear sides of the finger insertion part 52 in the connection region 50, the smaller the finger insertion part 52 area, the lower the connection force due to the provision of the finger insertion part 52. Can be suppressed. From such a viewpoint, for example, in the case of the first embodiment, it is preferable that the dimension in the front-rear direction of the finger insertion portion 52 (maximum value when changing) is in the range of 5 to 25 mm. The front-rear direction dimension of the cover piece 53 in the first embodiment is the same as the dimension of the finger insertion part 52.

  The size and shape of the opening 54 are limited by the size of the cover piece 53 when the cover piece 53 is formed of a material forming a portion in the opening 54. If there is no, the size and shape of the opening 54 can be determined as appropriate. In normal cases, considering the ease of insertion of the finger 60, it is desirable that the dimension in the width direction of the opening 54 is 10 to 50 mm, and the dimension in the front-rear direction of the opening 54 is 5 to 25 mm. The shape of the opening 54 can be determined as appropriate, such as a polygonal shape such as a triangle or a quadrangle, a circle, or an ellipse. In particular, as shown in FIG. 5 and the like, when the opening 54 has the shape of an arrow indicating the direction toward the finger insertion portion 52, the user inserts the finger 60 into the opening 54 and the direction in which the finger 60 is inserted. This is preferable because it is easy to recall.

(Other)
As shown in FIG. 6A, in the state where the fastening tape 5 is connected to the ventral part F, the color of the part viewed from the opening 54 in the ventral part F (for example, the color of the surface of the target tape 6 as shown in the figure). If the color around the opening 54 is different, it is preferable because the user can easily see the opening 54.

  The present invention can be used for a tape-type disposable diaper as in the above example.
