Description

  The present invention relates to a tape-type disposable diaper and a method for manufacturing and attaching a fastening tape.

  A general tape-type disposable diaper has a ventral part extending from the center in the front-rear direction to the front side and a back side part extending to the rear side, and has a fastening tape protruding from both sides of the back side part. And when mounting | wearing with a body, it has a structure which turns a fastening tape from the both sides of a waist to the ventral | abdominal outer surface, and latches to an abdominal outer surface.

  Such a tape-type disposable diaper is used not only for infants but also widely used for nursing care (adult use), but has a problem that the waist and legs are easily loosened.

  The solution of this problem has become one of the important issues of tape-type disposable diapers. One solution is to apply the waist-side end and the leg-around end of each side of the dorsal part. Fastening tapes are provided (see, for example, Patent Document 1), and the waist-side fastening tapes are locked while being pulled diagonally downward, so that the waist is firmly tightened, and the fastening tapes on the leg-surrounding side are pulled diagonally upward. There is a method of tightening around the legs by stopping.

  However, inexperienced users such as home caregivers often lock the fastening tape while pulling it straight in the horizontal direction, resulting in gaps around the waist and legs, resulting in leakage. May lead to

  In order to solve this problem, it was considered that the direction of the fastening tape was displayed on the outer surface of the abdomen. However, tilting and pulling the fastening tape at an angle may appear unnatural. Unless you are conscious of it, it will be a more natural wearing configuration, that is, a configuration in which it is pulled and locked straight in the lateral direction.

  Also, Patent Documents 2 and 3 propose that the fastening tape is inclined in advance in order to improve the fit around the waist and legs. However, the thing of patent document 2 cannot prevent the leg circumference loosening even if the waist circumference is tightened firmly, and the leg circumference looseness is affected, and the waist circumference of the dorsal part falls and eventually loosens around the waist. Is difficult to prevent. In addition, the one described in Patent Document 3 is provided with a waist-side fastening tape obliquely upward, and extends a portion around the leg obliquely downward along the leg circumference to lock its tip. If it is not consciously attached to an appropriate position in an appropriate direction, not only the loosening around the waist and the legs can be prevented, but also the structure is complicated and the manufacture is difficult.

  Therefore, a main problem of the present invention is to provide a tape-type disposable diaper that can be firmly tightened around both the waist and legs unconsciously even by an inexperienced user.

The present invention that has solved the above problems is as follows.
<Invention of Claim 1>
It is configured to cover the crotch from the wearer's ventral side to the back side,
Fastening tape having a root portion fixed to the side portion of the back side portion and a main body portion protruding outward in the width direction from the side edge of the back side portion is provided on both sides of the back side portion,
In mounting on the body, in the tape type disposable diaper, the fastening tape is turned from the both sides of the waist to the ventral outer surface and locked to the ventral outer surface,
While providing the fastening tape at the end on the waist side and the end around the leg in each side of the dorsal portion,
The upper edge and the lower edge of the body part of the fastening tape on the waist side are obliquely upward from the base end of the tape toward the tip, respectively, and the upper edge and the lower edge of the body part of the fastening tape on the leg circumference side are respectively The tape was slanted downward from the base end to the tip
This is a tape-type disposable diaper.

(Function and effect)
In the tape-type disposable diaper of the present invention, the upper edge and the lower edge of the waist-side fastening tape main body are obliquely upward from the base end of the tape toward the tip, respectively, By making the upper edge and the lower edge diagonally downward from the base end of the tape toward the tip, just pulling these fastening tapes straight in the lateral direction toward the center in the width direction, and around the waist of the back side part By pulling diagonally downward and diagonally upward around the legs on the dorsal portion, the waist and legs can be firmly tightened without being aware of the direction of the fastening tape. At this time, the portion between the waist-side fastening tape and the leg-surrounding-side fastening tape is left in a bowl shape, but this excess portion disappears toward the hip side, so there is no risk of leakage.

  In addition, when the upper and lower edges of the fastening tape are linear, the direction of the straight line means the direction of the upper and lower edges. For example, in the case of a curved or bent shape that bulges or sinks up or down, the direction of the approximate straight line (such as the least square method) means the direction of the upper edge and the lower edge.

<Invention of Claim 2>
The tape-type disposable according to claim 1, wherein the waist-side fastening tape and the leg-around fastening tape have an inclination angle of the upper edge and the lower edge of the main body with respect to the width direction of the diaper of 5 to 20 degrees. Diapers.

(Function and effect)
Although the inclination angle of the upper edge and the lower edge of the fastening tape can be determined as appropriate, it is preferably within this range in normal cases. In addition, as can be seen from the definition of “orientation” described above, when the upper and lower edges of the fastening tape are linear, the angle between the straight line and the diaper width direction means the above-mentioned inclination angle. In the case of, for example, in the case of a shape in which fine irregularities such as wavy are repeated, or in the case of a curved or bent shape that bulges or sinks up or down, the approximate straight line (least square method etc.) and the diaper width The angle made with the direction means the tilt angle.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

(Basic configuration)
1 to 6 show an example 100 of a tape-type disposable diaper according to the present invention. This disposable diaper 100 is composed of a back sheet 1 located on the back side and a liquid-permeable top sheet 2 in contact with the skin. The absorbent body 3 is interposed therebetween, and is configured to cover from the abdomen side of the wearer to the back side through the crotch. Here, the ventral part (front part) F means a part in front of the center in the front-rear direction, and the back part (rear part) B means a part in the rear from the center in the front-rear direction.

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. . 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 pulp in the absorbent body 4 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.

The back 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 back 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 backsheet 1 is preferably 13 to 40 g / m ² , and the thickness is preferably 0.01 to 0.1 mm.

  The back surface of the back sheet 1 is covered with an exterior sheet 12, and both side portions of the exterior sheet 12 extend outward from the side edges of the back sheet 1. 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. In this case, the back sheet 1 is formed in the same shape as the exterior sheet 12.

The top sheet 2 extends outward from the periphery of the absorber 3, and a portion extending outward from the side edge of the absorber 3 is fixed to the back sheet 1 by a hot melt adhesive or the like. In addition, the diagonal line pattern in a figure represents the adhering part. As the top sheet 2, a perforated or non-porous nonwoven fabric or a perforated plastic sheet is used. As the material fiber constituting the nonwoven fabric, synthetic fibers such as polyethylene or polypropylene, synthetic fibers such as polyester and amide, recycled fibers such as rayon and cupra, and natural fibers such as cotton can be used. The basis weight of the nonwoven fabric used for the liquid-permeable top sheet 2 is preferably 15 to 30 g / m ² , and the thickness is preferably 0.05 to 1 mm.

  As shown in FIGS. 3 and 4, both sides of the inner surface of the article (in the illustrated form, the surface of the exterior sheet 12 extending from the side edge surface of the top sheet 2 to the side thereof) The portion 4x on the outer side in the width direction is pasted over the entire front-rear direction. As the barrier sheet 4, various non-woven fabrics (preferably spunbonded non-woven fabrics), plastic films similar to those used for the back sheet, or laminated sheets thereof can be used. Thus, a nonwoven fabric subjected to water repellent treatment is suitable. The central portion 4c in the width direction of the barrier sheet 4 is fixed to the inner surface of the article (the surface of the top sheet 2 in the illustrated embodiment) at both ends in the front-rear direction by means such as hot melt adhesive. Is a non-fixed free part, and an elongate elastic expansion / contraction member 4G is stretched along the front-rear direction at the tip of the free part (end on the center side in the width direction in the unfolded state). It is fixed with agents. As the elongated elastic elastic member 4G (the same applies to other elongated elastic elastic members), a styrene rubber, an olefin rubber, a urethane rubber, an ester rubber, a polyurethane formed in a thread shape, a string shape, a belt shape, or the like. Commonly used materials such as polyethylene, polystyrene, styrene butadiene, silicon, and polyester can be used. As shown in FIG. 4, this free portion constitutes a barrier that stands up against the inner surface of the article (the surface of the top sheet 2 in the illustrated embodiment) as a result of the contraction force of the elongated elastic elastic member 4G. The base end 4b of the standing portion is positioned at the boundary between the outer fixed portion 4x and the inner portion 4c in the barrier sheet 4.

  At both ends in the front-rear direction of the disposable diaper 100, the back sheet 1, the exterior sheet 12, the liquid-permeable top sheet 2, and the barrier sheet 4 are respectively extended from the front and rear ends of the absorbent body 3 to the front and rear sides. A non-end flap portion EF is formed.

  On the other hand, on the left and right side portions of the disposable diaper 100, the back sheet 1, the exterior sheet 12, the liquid-permeable top sheet 2 and the barrier sheet 4 are respectively extended from the side edges of the absorbent body 3 to the side of the absorbent body 3. Side flap portions that do not exist are formed, and between the seats in each side flap portion (between the back seat 1 and the top seat 2 in the illustrated example), from the waist side portion of the ventral portion F to the waist side of the back portion B Up to the portion, a plurality of elongated elastic elastic members 30 are sandwiched and fixed in a state where they are extended in parallel and spaced in the longitudinal direction.

  Of the side flap portions, the portions located in the waist side portion of the abdominal side portion F and the waist side portion of the back side portion B are extended laterally from the intermediate portion therebetween, and these portions are The waist side side flap part SF which becomes a waist part of a diaper is comprised, respectively, The lower edge forms the edge along a leg periphery. The longitudinal length of the side edge of the waist side side flap part SF of the ventral part F is shorter than that of the back part B.

(Fastening tape)
Fastening tapes 5 and 6 are attached to the both side waist flaps SF of the back portion B so as to protrude outward in the width direction from the waist-side end and the leg-around end of the side edge, respectively. . Moreover, the target tape 7 is stuck along the width direction on the surface of the waist part of the abdominal part F, and when attaching to the body, the fastening tapes 5 and 6 on both sides are placed with the diaper 100 applied to the body. Is attached to the target tape 7 by rotating from each side of the waist to the outer surface of the ventral side. The target tape 7 can be omitted. In this case, the fastening tapes 5 and 6 are fixed directly to the outer surface of the diaper (in the illustrated embodiment, the exterior sheet 12).

  The fastening tapes 5 and 6 have a root portion 8B fixed to the side portion of the back side portion B by a hot melt adhesive or the like, and a main body portion 8A protruding outward in the width direction from the side edge of the back side portion B. In the example shown in the figure, the substrate 8A, 8B constituting the whole and a locking portion 9 provided on the inner surface of the intermediate portion in the width direction of the main body 8A. As the base materials 8A and 8B, known materials such as non-woven fabrics, resin sheets, and laminates thereof can be used, and the locking portion 9 is made of an adhesive or a hook tape (male material) of a mechanical fastener (surface fastener). Can be formed.

  Characteristically, as shown in FIGS. 1 and 5, the upper edge d and the lower edge e of the main body portion 8A of the fastening tape 5 on the waist side are inclined upward from the base end to the tip end of the tape, respectively. An upper edge d and a lower edge e in the main body portion 8A of the surrounding fastening tape 6 are respectively inclined downward from the base end to the front end of the tape. Accordingly, as indicated by the white arrows in FIGS. 6 and 7, the fastening tapes 5 and 6 are simply pulled straight in the lateral direction toward the center in the width direction, and attached around the waist of the back portion B. The legs around the legs of the back portion B are pulled obliquely upward, and the waist and legs can be firmly tightened without being aware of the direction of the fastening tapes 5 and 6. At this time, the portion 10 between the waist-side fastening tape 5 and the leg-surrounding-side fastening tape 6 is left in a bowl shape, but the excess portion 10 disappears toward the hip side, so there is no risk of leakage.

  Although the shape of the specific fastening tapes 5 and 6 can be determined as appropriate, the root portion 8B is arranged in the vertical direction so that the fastening tape does not come off the diaper even when the tape is attached to the target tape 7 so as to pull the tape body portion 8A. It is preferable to take a long bonding area so that the main body 8A has a shape that is long in the lateral direction in order to improve the operability of mounting on the target tape 7. As the shape of the main body 8A, for example, the upper edge d and the lower edge e are not parallel (but the inclination direction is the same) as well as a straight line in which the upper edge d and the lower edge e are parallel as in the illustrated example. Linear shape, at least one of the upper edge d and the lower edge e is curved or bent, and at least one of the upper edge d and the lower edge e has a shape with repeated irregularities such as wavy, or the upper edge d and the lower edge The body portion 8A as a whole that intersects with e at the tip can have a substantially triangular shape. In these cases, the directions of the upper edge d and the lower edge e of the fastening tapes 5 and 6 are as defined above.

  Although the inclination angle of the upper edge d and the lower edge e of the fastening tape 5 on the waist side and the fastening tape 6 on the leg circumference side can be determined as appropriate, the upper edge d and the upper edge d of the main body portion 8A with respect to the width direction of the diaper is normal. The inclination angle θ of the lower edge e is preferably 5 to 20 degrees, particularly 10 to 15 degrees.

  In the present invention, although the direction of the fastening tapes 5 and 6 is inclined, the fastening tapes 5 and 6 are attached to the abdominal portion F because the fastening tapes 5 and 6 are not inclined when locked to the ventral outer surface but are locked straight in the width direction. It is preferable to provide a linear mark along the width direction as a mark for attaching the. Such a mark can be formed by an appropriate method. However, when the target tape 7 is provided, the upper edge d and the lower edge e may be formed in a straight line along the width direction as a mark. As described above, the linear mark 7p may be printed on the constituent member of the ventral portion F (the target tape 7 in the illustrated example, but may be the exterior sheet 12, the back sheet 1 or the like). Further, when such a mark 7p is provided, if the upper edge d and the lower edge e of the main body portion 8A of the fastening tapes 5 and 6 are linear, the fastening tapes 5 and 6 are locked to the target tape 7. At this time, the direction of the fastening tapes 5 and 6 is more unconsciously straight sideways.

  Furthermore, as shown in the figure, when a plurality of linear marks 7p along the width direction are provided at intervals in the vertical direction, the waist side edge of the ventral part F and the waist side edge of the back part B are combined. As described above, when the diaper 100 is folded in half with respect to the center in the front-rear direction, at least the distal end portion of the body portion 8A of the waist-side fastening tape 5 is located on the waist side more than the mark 7p on the most waist side, When at least the tip of the main body 8A of the fastening tape 6 is configured to be located on the leg circumference side with respect to the mark 7p on the most leg circumference side, the user can fasten the fastening tape 5 on the waist side and the leg circumference side. Even if it is attempted to lock 6 to the ventral portion F in an inclined state, it protrudes from the mark 7p, so that it is naturally guided to the above-described wearing state of the present invention.

  The size and shape of the root portion 8B can be appropriately determined according to the required strength or the like, but in the present invention, the portion 10 between the waist side fastening tape 5 and the leg periphery side fastening tape 6 in the mounted state. Therefore, if the base portion 8B of the fastening tapes 5 and 6 is present in the surplus portion 10, the surplus portion 10 becomes hard and thick, resulting in deterioration of wearing feeling and the like. Therefore, as shown in FIG. 9, the fastening tape 5 on the waist side has a lower edge e of the root portion 8B that is located on the waist side or the same as the extension line of the lower edge e of the main body portion 8A. The fastening tape 6 on the side is formed in the shape of the fastening tapes 5 and 6 so that the upper edge d of the root portion 8B is positioned on the same side as the extension line of the upper edge d of the main body portion 8A or on the waist side. I also propose.

  In this way, by preventing the root portions 8B of the fastening tapes 5 and 6 on the waist side and the leg-surrounding sides from extending to the opposite sides, the waist-side and leg-around fastening tapes 5 and 6 are straightened in the lateral direction. When pulled, the portions between the waist-side fastening tape 5 and the leg-side fastening tape 6 on both sides of the back-side portion B are flexibly deformed so that the above-described wearing state of the present invention can be more easily formed. become.

(Fastening tape manufacturing and mounting method)
On the other hand, when manufacturing the tape-type disposable diaper 100 described above, the fastening tapes 5 and 6 can be manufactured and attached by the following method. That is, as shown in FIG. 8, in the first fastening tape manufacturing process, the continuous belt-shaped first base material 21 is transferred along the continuous direction, and the continuous belt-shaped first locking portion is formed on the center in the CD direction. After the 22 (hook tape or adhesive layer) is pasted along the MD direction, a periodic wavy line extending along the MD direction while reciprocating in the width direction so as to cross the first locking portion 22 Fastening tape 5 on the left waist side from the divided part on the one side in the CD direction by cutting at a transverse cutting line 24 that divides into two at 23 and intermittently crosses the CD direction with a predetermined interval in the MD direction. And the fastening tape 6 on the right leg circumference side from the divided part on the other side in the CD direction.

  Further, in parallel with the first fastening tape 5 and 6 manufacturing process, in the second fastening tape manufacturing process, while the continuous belt-like second base material 25 is transported along the continuous direction, After the continuous belt-like second locking portion 26 is pasted along the MD direction, the periodic wavy shape extending along the MD direction while reciprocating in the width direction so as to cross the second locking portion 26 Fastening tape on the right waist side from the divided part on one side in the CD direction by cutting along a transverse cut line 28 that bisects in the MD direction and intermittently crosses in the CD direction with a predetermined interval in the MD direction 5 and the fastening tape 6 on the left leg periphery side from the divided part on the other side in the CD direction.

  In manufacturing these fastening tapes 5 and 6, the first locking portion 22 and the second locking portion 26 are attached to the first base material 21 and the second base material 25 by a known fixing means such as a hot melt adhesive. Can do.

  The left waist fastening tape 5 and the right leg fastening tape 6 formed in the first fastening tape manufacturing process, and the right waist fastening tape 5 formed in the second fastening tape 5 and 6 manufacturing process, and The fastening tape 6 on the left leg circumference side is supplied to the diaper production line, is attached to both sides of the back side portion B of the diaper in the fastening tape attaching process, and is folded to the inner side of the diaper as necessary. By such a method, the tape-type disposable diaper 100 of the present invention can be manufactured without waste and only by changing the division pattern of the existing technology.

  In addition, as shown in FIG. 10, after affixing the 1st latching | locking part 22 and the 2nd latching | locking part 26 to the 1st base material 21 and the 2nd base material 25, it interrupts at predetermined intervals in MD direction. When cutting along the transverse cutting lines 24 and 28 that cross in the CD direction, the cutting lines 24 and 28 are connected to the upper edge d (or the lower edge e) of the main body portion 8A included in the periodic wavy lines 23 and 28, respectively. Fastening tapes 5 and 6 of the type shown in FIG. 9 can be manufactured by crossing the line.
