Description

  The present invention relates to an absorbent article suitable as a flat type auxiliary absorbent article used in combination with a basic absorbent article such as a pad type, a tape type, and a pants type.

In addition to basic absorbent articles (also called outer) such as pad type, tape type, and pants type, excrement absorbent articles (diapers) for adults are expected to be used in combination with these. What is called a type is provided, and these combinations are widely used particularly in nursing care sites such as care facilities.
That is, in the case of a wearer or the like in which crimping has occurred, it may be difficult to properly fit the wearer's body surface with only the above basic absorbent article. The auxiliary absorbent article is deformed into an appropriate shape such as a loose shape, and is sandwiched in the gap between the body surface and the basic product (or the part where gaps are likely to be generated), or rolled into a cone when the wearer is male. A measure such as winding around the penis (hereinafter also referred to as male winding) has been taken (see, for example, Patent Documents 1 and 2).

On the other hand, in patent document 3, the structure provided with the corner | surface part fastener 41 in the four corner | angular parts of the main-body part 1 which is an auxiliary | assistant absorbent article is shown. And these corner | angular surface fastener 41 comes to be used as an absorption pad which receives the excretion from a wearer by fixing to the inner side of a basic absorbent article.
Along with this, the absorbent article of Patent Document 3 has the edge portion folded back to the back sheet side at one end portion in the longitudinal direction of the main body portion 1 and fixed to the corner surface fastener 41. The corners are folded back to the top sheet side and fastened to each other by the corner surface fasteners 41, so that the male wrap around the penis is used as a male urine absorbent article.

Hereinafter, an embodiment of the present invention will be described in detail with reference to an example of an auxiliary absorbent article used in combination with a basic absorbent article such as a tape-type disposable diaper.
(First form)
1 and 2 show a first form of the auxiliary absorbent article 100. This auxiliary absorbent article is a flat-type absorbent article in which an absorbent body 3 capable of absorbing liquid is interposed between a back sheet 1 and a top sheet 2 each formed of a nonwoven fabric and having liquid permeability. is there. Since the back sheet 1 and the top sheet 2 each have liquid permeability, liquid permeation in the front and back directions is possible on both surfaces of the auxiliary absorbent article 100.

  Around the absorber 3, a flap 5 is formed by fusing the protruding portions of the top sheet 2 and the back sheet 1 together. The flaps extending on both sides in the longitudinal direction of the absorber 3 are end flaps, and the flaps extending on both sides in the width direction of the absorber 3 are side flaps. The flap 5 may be formed around the absorber 3 by adding one of the top sheet 2 and the back sheet 1 or another sheet. In the illustrated example of the flat type auxiliary absorbent article 100, an elongated elastic elastic member may be fixed in an extended state along the front-rear direction between the top sheet 2 and the back sheet 1 on both sides.

  Characteristically, a perforation M1 is formed along the longitudinal direction in the portion of the flap 5 on both sides in the width direction near one side (the upper end side in FIGS. 1 and 2) with respect to the center in the longitudinal direction of the auxiliary absorbent article 100. Are formed respectively. The perforation M1 extends from the end of the absorbent body 3 to a position that is about one third of the longitudinal direction of the absorbent body 3. The perforation M1 changes at a right angle to the outer end of the flap 5 at this position. M1 exists. Further, a perforation M2 along the width direction is formed at the center portion in the width direction of the flap 5 located at the end portion on the other side (the lower end side in FIGS. 1 and 2) with respect to the center in the longitudinal direction of the auxiliary absorbent article 100. Has been. The perforation M1 and the perforation M2 can be easily formed on the flap 5 by using a leg circumference cutter in a general manufacturing apparatus.

  On the other hand, as shown in FIG. 2, a locking portion 8 is provided in the vicinity of the perforation M2 (string insertion hole 7) on the back surface (made of the back sheet 1 in the illustrated example) of the auxiliary absorbent article 100. Yes.

  In use, the user cuts the perforations M1 on both sides in the width direction on the one side in the longitudinal direction of the auxiliary absorbent article 100, so that this portion becomes a string shape, and on both sides in the width direction in the one side in the length direction. A pair of string portions each having a root portion is formed. Further, by separating the perforation M2 located at the end portion on the other side in the longitudinal direction of the auxiliary absorbent article 100, this portion becomes a slit-like string insertion hole 7 penetrating the front and back. Then, as shown in FIGS. 3, 4 and 10, the pair of string portions 6 are passed through the string insertion holes 7 from both sides of the penis from the surface side of the article, and are further locked to the locking portions on the back surface side. By doing so, the middle part of the base part of the string part 6 and the string insertion hole 7 can be folded in half as a folded part and fixed in a folded state with the penis IK sandwiched therebetween. At this time, the portion on one side in the longitudinal direction of the string portion 6 has a substantially truncated conical cylinder shape so as to wrap the penis, and the top portion side of the cylindrical portion fits to the root of the penis IK, and this state is maintained. . Moreover, it becomes possible to adjust the magnitude | size of the roundness for putting a penis by squeezing a pair of string part 6 which passed the string insertion hole 7, for example.

  The locking portion 8 can be installed by applying an adhesive layer to the surface of the backsheet 1. The locking portion 8 may be disposed within the reach of both the strap portions 6 from the viewpoint of fixing the strap portion 6, but if the distance from the strap insertion hole 7 is increased, the above-described two-fold mounting state may be loosened. Therefore, it is installed in the vicinity of the string insertion hole 7. If the string portion 6 has a fiber layer entangled with a hook of a male tape such as a non-woven fabric surface, the male tape (hook) of a mechanical fastener (surface fastener) such as a magic tape (registered trademark) is used as the locking portion 8. Material) can also be adopted.

Next, the operation of the auxiliary absorbent article 100 according to this embodiment will be described below.
According to the auxiliary absorbent article 100 of the present embodiment, a part of the absorbent body 3 is rolled so as to be wound around the penis, and the string insertion hole 7 is formed in a state where the absorbent body 3 is bent in a bi-fold shape near the central portion. This state can be maintained because the distal end sides of the pair of inserted string portions 6 are securely fixed by the locking portions 8. Since such a state can be maintained, it is possible to effectively prevent the auxiliary absorbent article 100 from being displaced or detached from the penis.

  Furthermore, when a part of the absorbent body 3 is rounded, even if the penis size is different, a penis hole formed by rounding by changing the insertion degree of the pair of string portions 6 into the string insertion hole 7 The size of the lens can be adjusted, and the shape is stabilized without any change in shape even when the wearer moves or bulges after absorption of urine. On the other hand, according to the auxiliary absorbent article 100 of the present embodiment, the locking portion 8 fixes the distal end side of the string portion 6 to the surface of the backsheet 1, so that the locking portion 8 such as a hook-and-loop fastener is used as the penis. There is no fear of hitting, and the feeling of wearing is improved. Further, if the locking part 8 is mounted so as to be located on the opposite side of the scrotum, the part of the locking part 8 exposed around the string part 6 is fixed to the surface of the basic absorbent article or underwear (outer). It is possible to prevent the auxiliary absorbent article 100 from being displaced from the basic absorbent article. Of course, an adhesive layer or a male tape of a mechanical fastener (surface fastener) can also be provided at a position different from the engaging portion 8 on the back surface for preventing misalignment.

  On the other hand, a perforation M1 and a perforation M2 are formed on the flap 5, respectively, and a pair of string portions 6 are provided to be separable from the absorber 3, and a slit-like string insertion hole 7 is provided to be openable. The pair of string portions 6 and the string insertion holes 7 can be easily formed simply by providing the perforations M1 and M2 at locations necessary when the auxiliary absorbent article 100 is manufactured. Furthermore, if there is a pair of string portions 6, this state can be easily maintained when one end side in the length direction of the auxiliary absorbent article 100 is rounded into a cylindrical shape. Further, if only one string insertion hole 7 is provided, a pair of string portions 6 can be fixed by a single locking portion 8, and the pair of string portions are formed at the opposite end of the absorber 3. 6 can be fixed at once.

  Here, as the top sheet 2 in the auxiliary absorbent article 100, a perforated or non-porous nonwoven fabric, a perforated plastic sheet, or the like 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.

  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. . If necessary, the absorber 23 can be wrapped with crepe paper (not shown). In addition, the shape of the absorbent body 23 can be determined as appropriate, and in the illustrated example, in order to improve the fit to the inside of the thigh, the front-rear direction intermediate region including the crotch portion C2 has a constricted shape along the leg circumference. A rectangular shape or the like can also be used.

The fiber basis weight and the basis weight of the absorbent polymer in the absorbent body 3 can be appropriately determined. The fiber basis weight is preferably about 250 to 500 g / m ^2, and the basis weight of the absorbent polymer is about 50 to 250 g / m ^2. Is preferable.

  As the back sheet 1, the same liquid-permeable material as that of the top sheet 2 can be suitably used. If the front and back surfaces are not liquid-permeable, but only the surface has liquid permeability and the back does not allow liquid penetration, the backsheet 1 can be made of polyethylene film, etc. It is also possible to use a sheet having moisture permeability without impairing water shielding. This water-impervious / breathable 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. Even in such a moisture-permeable sheet, the transmission of odor is suppressed. When using these liquid-impermeable sheets, in order to make the back surface of the pad-type absorbent article feel like a cloth, an outer sheet such as a non-woven fabric is laminated on the outer surface of the back sheet, or a non-woven fabric is used on the outer surface as a back sheet. Laminated laminate sheets can be used. As raw materials for these non-woven fabrics, 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 size and shape of the auxiliary absorbent article 100 can be determined as appropriate, but in a normal case, the width W2 of the auxiliary absorbent article 100 is preferably about 60 to 250 mm, and the length L2 of the auxiliary absorbent article 100 is The thickness is preferably about 150 to 500 mm.

  Since the illustrated example is an auxiliary absorbent article, it does not have solid gathers protruding on the body side on both sides in the width direction of the surface. It is possible to adopt a known additional structure in the absorbent article, such as providing

(Second form)
In the present embodiment, as shown in FIG. 5, the perforation M <b> 1 on both side portions of the auxiliary absorbent article 100 extends to the other end side without bending at a right angle on the way. For this reason, in this embodiment, the pair of string portions 6 has a length that is about 5 mm shorter than the entire length of the auxiliary absorbent article 100, which is about three times that of the first embodiment. That is, by increasing the length of the pair of string portions 6 in this manner, the degree of freedom when using the auxiliary absorbent article 100 is further increased.

(Third form)
In the present embodiment, as shown in FIGS. 6 and 7, a pair of perforations M <b> 1 exist so as to immediately face the outer end of the flap 5. In addition, a perforation M2 extending in the same direction as that of the first embodiment is formed in a central portion near the other end of the auxiliary absorbent article 100 and in the absorbent body 3.

  Along with this, the pair of string portions 6 is shortened, so that the locking portion 8 of the present embodiment is barely at the other end of the auxiliary absorbent article 100 which is the reverse of the first embodiment as shown in FIG. It is conceivable to arrange them at places. That is, when shortening a pair of string parts 6 like this embodiment, it is possible to arrange the string penetration hole 7 by the perforation M2, and the locking part 8 according to this. In addition, you may arrange | position the latching | locking part 8 so that the string insertion hole 7 may overlap.

(4th form)
In the present embodiment, as shown in FIG. 8, a pair of perforations M1 are formed in the same manner as in the first embodiment, but circular string insertion holes 7 are formed instead of the perforations M2. From this, insertion of a pair of string part 6 with respect to the string insertion hole 7 becomes easier. Moreover, the absorber 3 of this embodiment is formed in the form except the circumference | surroundings of the string insertion hole 7, and the protrusion part 3A is extended from the absorber 3 to the both sides of the string insertion hole 7, respectively.

  From the above, the wearer or the like does not need to open the string insertion hole 7 later, and the absorber 3 does not leak into the string insertion hole 7 from the periphery of the string insertion hole 7. However, if there is no leakage of the absorbent body 3, the absorbent body 3 may be arranged including the periphery of the string insertion hole 7.

(5th form)
In this embodiment, as shown in FIGS. 9 and 10, the portion on one side in the longitudinal direction of the backsheet 1 is covered with a water repellent nonwoven fabric 9 </ b> A that becomes liquid-impermeable, and the portion 9 </ b> B on the other side in the longitudinal direction. Are exposed without being covered. The length dimension of the water-repellent nonwoven fabric 9A can be determined as appropriate, but is usually about 3 cm at the shortest and about one-half of the length of the auxiliary absorbent article 100 at the longest.

  According to the present embodiment, when the auxiliary absorbent article 100 is attached, the portion between the pair of perforations M1 of the backsheet 1 is attached to the scrotum IN located below the penis IK as shown in FIG. Will be in touch. Without this water-repellent nonwoven fabric 9A, urine that has passed through the back sheet 1 may adhere to the scrotum IN and cause skin troubles such as the scrotum IN being rashed. The nonwoven fabric 9 blocks urine and skin trouble does not occur. In place of the water-repellent nonwoven fabric 9 of the present embodiment, the nonwoven fabric may be silicone-treated, or a liquid-impermeable resin sheet such as polyethylene may be attached instead of the water-repellent nonwoven fabric 9A.

(Other)
The string insertion hole 7 can be provided at a plurality of locations. For example, although the illustrated example has a form provided at one central portion in the width direction, instead of or together with this, at least one string insertion hole is provided symmetrically with respect to the width direction center on both sides of the width direction center. Can be provided.

  The present invention is suitable for auxiliary absorbent articles used in combination with basic absorbent articles such as pad type, tape type, pants type, etc., but by using a liquid-impermeable sheet as a back sheet, It can also be used as an absorbent article.
