Description

The present invention relates to an absorbent article used as a male underwear, and particularly as an incontinence countermeasure article for adult males.

  An incontinence pant having a so-called urine absorption pad that can absorb a small amount of urine as a countermeasure against mild incontinence is known. This incontinence pant is an integrated pant body and urine absorption pad that is easy for the wearer to attach and detach, and the feeling of wearing is not so great compared to normal underwear. In some cases, it can be worn as if it were underwear.

  In the case of men with a light degree of incontinence of the wearer of such incontinence pants, it is also desired to be able to urinate in a standing posture with respect to the toilet for men, from such a viewpoint, Patent Document 1 proposes a perforated type absorbent article specialized for men.

JP 2013-154038 A

  In the absorbent article for mild incontinence proposed in Patent Document 1, the central portion of the urine absorption pad that most needs to absorb urine in order to secure the front perforated structure is a void. For this reason, if a wearer is incontinence in such a state, urine may leak out of the exterior sheet from this void portion. In particular, when the wearer is leaning forward or sitting on a chair, the urine absorption pad will bend in the vertical direction and the gap will expand, so if incontinence occurs in this state, urine will almost certainly be Leak out of the exterior sheet.

  An object of the present invention is to provide an absorbent article in which a man can easily urinate in a standing position with respect to a male toilet and can prevent the above-described problems in the cited document 1 in advance. There is.

An absorbent article according to the present invention has a front body region and a back body region, and an outer sheet in which a waist opening and a pair of left and right leg openings are formed,
A liquid-impermeable back sheet disposed in at least the front body region of the inner side surface of the exterior sheet, a liquid-permeable top sheet joined to the back sheet, and a space between the top sheet and the back sheet An absorbent main body having an absorbent body disposed on the outer sheet, and the exterior sheet further includes a slit extending from the front body region toward the rear body region, and the absorbent main body includes the waist The edge on the side of the surrounding opening and the edge on the side close to the back body region and the side edge on the side near the one leg opening are joined to the exterior sheet so as to surround the slit, From the other side edge near the opening around the other leg to the portion surrounding the slit, the outer sheet is in a non-bonded state.

  In a state where the absorbent article is worn, the wearer's penis is in contact with the surface of the top sheet of the absorbent main body. In this state, if the male wearer of the absorbent article can urinate in a standing position with respect to the toilet for men, insert a finger from the slit formed on the exterior sheet and slit from the side edge of the absorbent body The penis is pulled out of the slit through a non-bonded area between the outer sheet and the outer sheet that reaches the portion surrounding the urine, and urination is performed. Thereafter, the penis is pushed back again so as to come into contact with the surface of the top sheet of the absorbent main body through a non-joining region between the slit and the exterior sheet extending from the slit to the side edge of the absorbent main body. On the other hand, when incontinence occurs while the wearer's penis is in contact with the surface of the top sheet of the absorbent main body, urine is immediately absorbed and retained by the absorbent body of the absorbent main body, and leakage to the outside is prevented. In the case of such incontinence, the wearer can change to a new absorbent article as necessary.

  In the absorbent article according to the present invention, it is effective to incline the slit with respect to the edge of the opening around the waist. In this case, it is preferable that the slit is formed along and closer to the one leg opening than the other leg opening.

  In addition, it is effective to further include a slit position display unit that can determine the position of the slit from the outside of the exterior sheet. In this case, the slit position display unit may use at least one of sight and touch. The slit position display unit using vision has a different hue with respect to the exterior sheet, and can include any of figures, characters, and regions. The slit position display unit using the tactile sense may be one in which the properties of the surface of the corresponding sheet are changed so that the touch is different from other parts.

  Also, the absorbent main body is arranged from the front body region to the back body region, and the width of the absorber in the crotch region between the front body region and the back body region is set to the width of the absorber on the waist side opening side. You may make it set narrower than.

  The absorbent main body is joined in a stretched state to a pair of side sheets extending along the left and right sides, and inner side edge portions of the pair of side sheets facing each other, and the inner side edge edges. A pair of elastic members extending along the portion, and the outer side edge portion side of the side sheet opposite to the inner side edge portion to which these elastic members are respectively joined is the top sheet side. Adsorbing along the side edge of the side sheet is the distance between the joints of the pair of side sheets on both sides of the absorbent body along the side edge of the side sheet. It can be set narrower than the interval between the joint portions of the pair of side sheets on the center side of the main body. In this case, a folded portion is formed by folding back side edges of the back sheet and the top sheet that overlap without passing through the absorber on the side close to the opening around the other leg, and the pair of side sheets forms the folded portion. It is preferable that each is joined to the surface of the absorbent main body so as to be wrapped.

  On the side close to the opening around the other leg, the folded back portion is formed by folding the side edges of the back sheet and the top sheet that do not pass through the absorbent body, and the absorbent main body is formed so as to wrap around the folded portion. It may further have a hydrophobic edge sheet bonded to the surface.

  According to the absorbent article of the present invention, the absorbent main body is in a non-bonded state with respect to the exterior sheet until it reaches the portion surrounding the slit from the side edge on the side close to the opening around the other leg. Similar to the case of wearing normal underwear, the male wearer can easily urinate in a standing position with respect to the male toilet. For this reason, it becomes possible to make it difficult for others to recall wearing incontinence products.

  In addition, when the slit is inclined, an exterior sheet is formed along the wearer's buttocks at the time of wearing, particularly by forming the slit closer to the one leg opening than the other leg opening. The slits can be made substantially parallel to the direction of the tension generated on the surface. As a result, a phenomenon that the slit opens unintentionally can be suppressed.

  When it further has a slit position display part which can discriminate | determine the position of a slit from the outer side of an exterior sheet | seat, when a wearer pulls out a penis part, the position of a slit can be grasped | ascertained easily using visual sense or touch.

  The absorbent main body is arranged from the front body region to the back body region, and the width of the absorber in the crotch region between the front body region and the back body region is larger than the width of the absorber on the waist opening side. When set narrowly, the wear feeling in the crotch part of the wearer when the absorbent article is worn can be improved.

  When the gap between the pair of side sheets on both ends of the absorbent main body along the side edge of the side sheet is set to be narrower than the gap on the center side, the gap between the pair of left and right side sheets serving as a three-dimensional gather The wearer's male genitalia can be stably held. Thereby, even if there is incontinence, it becomes possible to prevent urine from leaking from the left and right side ends of the absorbent main body to the exterior sheet side. In particular, the side sheets of the back sheet and the top sheet or the side sheet that overlap without passing through the absorber are folded and joined to the skin contact surface side, so that the liquid impermeable back sheet can be connected to the side of the absorber. The end edge is wrapped, and urine absorbed in the absorbent body can be prevented from oozing out from the width direction side edge of the absorbent main body. Here, a three-dimensional gather may be formed by providing a free end on the center side of the absorbent main body in the side sheet and disposing an elastic member on the free end. Moreover, in order to avoid that the back sheet which is not touching touches a wearer's skin, you may arrange | position a nonwoven fabric on the outer side of a back sheet.

  In addition, a hydrophobic edge joined to the surface of the absorbent main body so as to fold back side portions of the back sheet and the top sheet that are not interposed through the absorbent body to form a folded portion and wrap the folded portion on the absorbent main body. If it is set as the structure which has a sheet | seat, it can prevent that the urine absorbed by the absorber oozes out from the width direction side edge of an absorptive main body. In this case, a three-dimensional gather may be formed by providing a free end portion at the side end portion of the edge sheet on the skin contact surface side and disposing an elastic member at the free end portion. In addition, it is possible to avoid the back sheet that is not soft to the touch due to the presence of the edge sheet from coming into contact with the wearer's skin.

It is a three-dimensional projection figure showing typically the appearance of one embodiment which applied the absorptive article by the present invention to incontinence pants. It is a top view which expand | deploys the incontinence pants by this embodiment shown in FIG. 1, and shows the inner side. It is the top view which extracted and expanded the part of the absorptive main body in embodiment shown in FIG. It is an expanded sectional view along the IV-IV arrow in FIG. It is an expanded sectional view along the VV arrow in FIG.

  One embodiment in which the absorbent article according to the present invention is applied to disposable incontinence pants will be described in detail with reference to FIGS. However, the present invention is not limited to such an embodiment, and the configuration can be freely changed according to the characteristics required for the absorbent article.

  The external appearance of the incontinence pants according to the present embodiment is schematically shown in FIG. 1, and the inner planar shape obtained by breaking and developing the pants is shown in FIG. Further, the portion of the absorbent main body shown in FIG. 2 is extracted and enlarged, and a part thereof is broken and shown in FIG. 3, and the cross-sectional structures taken along arrows IV-IV and VV are shown in FIG. And schematically shown in FIG.

  The incontinence pant 10 according to the present embodiment includes a front body region 10F, a back body region 10R, and a crotch region 10C that connects the front body region 10F and the back body region 10R. Moreover, the waist periphery opening part 11 which surrounds a wearer's waist part by joining the front body area | region 10F and the back body area | region 10R mutually is formed. Similarly, a pair of left and right leg openings 12R, 12L that surround the thighs of the wearer's legs are formed by the lower end portions of the front body region 10F and the back body region 10R and the crotch region 10C.

  This incontinence pant 10 is an outer sheet 13, an inner sheet 14, and an absorbent main body 15 that are stacked and joined in order from the outside, and the inner sheet 14 for maintaining the wearer's feel well, It has the same shape as the exterior sheet 13.

  Between the outer sheet 13 and the inner sheet 14, an elastic member 16 such as a rubber thread for forming the leg gathers 12g and an elastic member 17 such as a rubber thread for forming the waist gathers 11g are provided. Joined in an extended state. It is also possible to form a waistline gather in addition to the waistline gather 11g. On the left and right sides of the crotch region 10C of the outer sheet 13 and the inner sheet 14, a pair of notch portions 12c having a semicircular arc shape that forms the leg periphery openings 12R and 12L are formed. The left and right side edges of the exterior sheet 13 that define the front body region 10F and the back body region 10R of the incontinence pants 10 together with the crotch region 10C are joined together with the inner sheet 14 to form a closing portion 10J. As a result, the front waist opening 11 and a pair of left and right leg openings 12R and 12L surrounding the thighs of both legs are defined.

  The exterior sheet 13 and the inner sheet 14 integrated therewith are formed with slits 18 extending from the front body region 10F toward the back body region 10R and for inserting and removing the wearer's penis P (see FIG. 4). Has been. The slit 18 in the present embodiment is formed along the leg opening 12R closer to the leg opening 12R than the other leg opening 12L while being inclined with respect to the edge of the waist opening 11. At times, consideration is given along the buttocks. The slit 18 may be formed close to the other leg opening 12L. The slit 18 in the present embodiment is formed by cutting the exterior sheet 13 and the inner sheet 14 with a cutter or the like so as not to generate chips, but is punched so as to have an elongated opening and has a width. Is also possible.

  The exterior sheet 13 has an elongated slit position display portion 18I having a hue that is clearly different from that of the exterior sheet 13, and the slit 18 described above is formed in the area of the slit position display portion 18I. The slit position display portion 18I can be formed in at least one of the outer sheet 13 and the inner sheet 14 facing the absorbent main body 15 and the surface of the absorbent main body 15 facing the inner sheet 14. In any case, the wearer can easily visually recognize the position of the slit 18 formed on the surface of the exterior sheet 13 by the slit position display portion 18I.

  Thus, in this embodiment, the area | region which has a different hue with respect to the exterior sheet | seat 13 was formed as the slit position display part 18I, However, Forming the slit position display part 18I using figures and characters, such as a character and an arrow. It is also possible to combine these further. Further, instead of visually grasping the position of the slit 18, it is also possible to grasp the position of the slit 18 using a tactile sense. For example, an elongated sheet that can be recognized as having a distinctly different feel to the surface of the exterior sheet 13 is joined to the exterior sheet 13 so as to overlap the slit 18, and the slit 18 is formed in the elongated sheet. Good. Alternatively, it is possible to join an elongated sheet to the surface of the exterior sheet 13 along the slit 18 formed in the exterior sheet 13 in advance.

  The absorbent main body 15 is arranged from the front body region 10F of the inner sheet 14 to the crotch region 10C. Then, the edge on the waist opening 11 side, the edge on the side close to the rear body region 10R, and the side edge near the one leg opening 12R surround the previous slit 18. In this way, it is joined to the inner sheet 14 to define a joining region 15J of the absorbent main body 15. In other words, the part of the absorbent main body 15 other than the joining region 15J defines a non-joining region 15N that is in a non-joining state with respect to the inner sheet 14 integrated with the exterior sheet 13. The non-bonding region 15N is formed between the non-joint region 15N and the inner sheet 14 from the side end edge near the other leg-hole opening 12L to at least a portion surrounding the slit 18. Therefore, the slit 18 is formed on the side edge of the absorbent main body 15 on the side close to the other leg-hole opening 12L via the non-joining region 15N between the inner sheet 14 and the absorbent main body 15 and the inner edge. The gap 19 formed between the sheet 14 and the sheet 14 is in communication.

  Therefore, in the incontinence pants 10 according to the present embodiment, the male wearer can perform the urination process in a standing posture with respect to the male toilet as in the case of normal underwear. That is, by inserting a finger from the slit 18 formed in the exterior sheet 13 through the non-joining region 15N of the absorbent main body 15 and the gap 19 above, and shifting the absorbent main body 15, the own penis P is slit into the slit 18. Can be pulled out of. Conversely, the penis P can be pushed back from the slit 18 through the non-joining region 15N and the gap 19 so as to contact the inner surface of the absorbent main body 15 (a top sheet described later).

  The absorbent main body 15 in this embodiment includes a liquid-impermeable back sheet 20, an absorbent body 21 for absorbing and holding urine, a liquid-permeable top sheet 22, a hydrophobic side sheet 23, and a thread. It is comprised with elastic members 24, such as rubber | gum.

  The back sheet 20 is for preventing urine absorbed in the absorbent body 21 from leaking from the absorbent body 21, and the top sheet 22 is formed in the form of a non-woven fabric so as to obtain a good touch. . The left and right end portions of the backsheet 20 and the topsheet 22 that overlap with each other without the absorber 21 form a folded portion 15T that is folded back with the backsheet 20 outside. It is possible to form the folded portion with the top sheet 22 facing outside, but in this case, the folded portion is hydrophobic so that urine does not ooze out from the absorbent body 21 through the top sheet 22. It is preferable to bond the conductive side sheet 23 to the surface of the absorbent main body 15.

  The absorbent body 21 disposed between the top sheet 22 and the back sheet 20 is obtained by dispersing SAP (Super Absorbent Polymer) in a fluff pulp having a mat shape and enclosing it with tissue. It is common. In this embodiment, the width dimension of the absorbent body 21 on the crotch region 10C side (in the left-right direction in FIG. 2) is set to be narrower than the width dimension of the absorbent body 21 on the waist opening 11 side. We consider so that there is less. The absorbent main body 15 may be arranged from the front body region 10F to the back body region 10R, and in this case also in the crotch region 10C between the front body region 10F and the back body region 10R. If the width dimension of the absorbent body 21 is set to be narrower than the width dimension of the absorbent body 21 on the waist opening 11 side, the uncomfortable feeling at the crotch portion when worn can be reduced.

  The hydrophobic side sheet 23 extends along both the left and right sides of the absorbent main body 15, and both longitudinal ends thereof are joined to the top sheet 22. The elastic members 24 are joined to the inner side edge portions in an extended state so as to extend along the inner side edge portions of the pair of side sheets 23 facing each other. The outer side edge portions of the side sheet 23 opposite to the inner side edge portions to which the elastic members 24 are joined are joined to the backsheet 20 so as to wrap around the folded portion 15T. Furthermore, the distance between the joint portions 23J of the pair of side sheets 23 on both ends of the absorbent main body 15 along the side edge of the side sheet 23 is the distance between the absorbent main body 15 along the side edge of the side sheet 23. It is set narrower than the interval between the joint portions 23J of the pair of side sheets 23 on the center side.

  Thereby, in a state where the incontinence pants 10 are worn, the side sheet 23 defines a three-dimensional gather 23g by the elastic force of the rubber thread 24, and urine from the left and right ends of the absorbent main body 15 to the exterior sheet 13 side at the time of incontinence. It functions as a weir that prevents leakage. Moreover, it becomes possible to hold | maintain a wearer's male instrument V stably between a pair of right and left solid gathers 23g in a wearing state. For this reason, even if there is incontinence, urine is immediately absorbed and held in the absorbent body 21 of the absorbent main body 15, and leakage to the outside can be reliably prevented.

  On the other hand, when the male wearer can urinate in a standing posture with respect to the male toilet, a finger is inserted through the slit 18 formed in the exterior sheet 13 and the side edge of the absorbent main body 15 What is necessary is just to pull out the own penis part P out of the slit 18 through the clearance gap 19 formed between the exterior sheets 13. Thereby, urination can be performed without polluting the absorbent main body 15 with urine. After that, if the penis P is pushed back again from the slit 18 through the gap 19 between the absorbent main body 15 and the exterior sheet 13 so as to be positioned between the left and right three-dimensional gathers 23g of the absorbent main body 15. Good.

  As described above, the distance between the slit 19 and the gap 19 formed between the side edge of the absorbent main body 15 on the side near the other leg opening 12L and the inner sheet 14 is large. While the incontinence pants 10 are worn, the slit 18 is covered with the absorbent main body 15. Thereby, even if the absorbent main body 15 is slightly displaced by the movement of the wearer, the slit 18 does not directly contact the wearer, and there is a possibility that urine may leak to the outside of the incontinence pant 10 through the slit 18. do not do. Moreover, when the absorbent main body 15 is shifted for urination and the male genital V is pulled out from the slit 18 and the male genital V is returned to the incontinence pants 10 again after urination, the absorbent main body 15 is separated from the wearer and the slit 18. It will naturally fit in the position between them. For this reason, there is no possibility that urine leaks through the slit 18.

  In the above-described embodiment, the pair of left and right side sheets 23 that define the three-dimensional gathers 23g are arranged on the absorbent main body 15. However, these side sheets 23 may be omitted to facilitate the insertion and removal of the male genital V. Is possible. In this case, it is desirable to prevent the male genital V from directly touching the back sheet 20 which is not comfortable to touch and to prevent the urine from seeping out from the absorbent main body 15 through the side end of the top sheet 22. For this reason, you may make it join the hydrophobic edge sheet | seat formed with the nonwoven fabric with favorable touch to the side edge part of the back sheet | seat 20 instead of the side sheet 23 mentioned above. In this case, the edge sheet is arranged so as to wrap around the folded portion 15T so that the back sheet 20 does not touch the wearer's skin.

  It should be noted that the present invention should be construed only from the matters described in the claims, and in the above-described embodiment, all the changes and modifications included in the concept of the present invention are other than those described. Is possible.
