Description

  The present invention relates to a compact and bulky urine absorbent pad for men that can hold a relatively small amount of urine.

Note that the "absorbent" to hold it absorbs urine described herein, fluff pulp and super absorbent polymer: not (SAP S uper A bsorbent P olymer ) only, these It is also intended to include a tissue or a sheet for maintaining the shape in a desired shape.

  Many people who are seriously bedridden and need urination care use a combination of a deployable disposable diaper and a urine pad in a time zone when the amount of urination is large at night. In this case, the urine pad functions as a main component of urine absorption, and the deployable diaper is used as an auxiliary role such as a diaper cover. In the case of men, since the penis part moves and urine leaks from the urine pad, a urine pad of the type wound around the penis part as disclosed in Patent Document 1 is also known. On the other hand, the existence of men of the middle age (30's) who have trouble with nocturnal enuresis caused by social stress is also becoming known. For men who do not need such care, it is possible to use a pants-type disposable diaper that can be attached and detached by one person, a urine pad that can hold a relatively small amount of urine, and the like.

  Conventional absorbent products such as disposable diapers and urine pads used for the above-mentioned purposes are absorbent bodies for absorbing and holding urine between a liquid-impermeable cover sheet and a liquid-permeable skin contact sheet. Generally, it has a structure with intervening. The liquid-impermeable cover sheet has a function of covering the absorber in order to prevent leakage of urine, but a polyethylene film or the like in which minute ventilation holes are formed is used to provide moisture permeability. The absorbent body is mainly configured by mixing a fluffy pulp and a superabsorbent resin (hereinafter referred to as SAP) into a mat shape and wrapping it with a covering material such as tissue.

  In the case of a male urine pad, it is necessary to make the urine pad follow the movement of the penis while wearing, but the conventional one is insufficient in this regard, and the urine is detached from the urine pad during wearing Often leaked out of the urine pad.

  Moreover, in what was disclosed by patent document 1, since the bulky urine pad was folded and wound around the penis part, a crotch part abnormally swelled and disturbed daily walking operation | movement, and uncomfortable feeling. However, there was a drawback that the feeling of wearing was remarkably impaired.

  An object of the present invention is to provide a urine pad that can maintain a proper wearing state with respect to a penis part more reliably than the conventional one and has a good wearing feeling.

  The first aspect of the present invention is a rectangular cover sheet having a front surface portion and a back surface portion, an absorber provided on the back surface side of the cover sheet for absorbing and holding urine, and a central portion of the absorber. Bonding tape that is joined to the back side of the cover sheet and wrapped around the penis part of the male genital so that both ends overlap each other, and provided at both ends of this tethering tape and overlaps each other A pair of joints for releasably joining the parts, and an elastically deformable layer formed on the tether tape so as to abut the penis part of the male genitalia and compressible in the thickness direction of the tether tape The urine absorption pad is characterized by.

  In the present invention, the back of the urine absorption pad is overlapped so that it touches the penis part of the male genitalia. In this state, the left and right free ends of the tethering tape are wrapped and overlapped with each other. These are connected. The elastic deformation layer is held in a compressed state between the tethering tape and the penis part of the male genitalia, whereby the urine absorbing pad is held in the penis part. Urine is absorbed and held by an absorber provided on the back surface of the urine absorption pad.

  In the urine absorption pad according to the present invention, a liquid-permeable skin contact sheet can be bonded to the back surface of the cover sheet, and the skin can be held with the absorbent body sandwiched between the skin contact sheet and the cover sheet.

  In this case, a nonwoven fabric, a synthetic resin film, or a laminated sheet obtained by superimposing these can be used as the cover sheet. Examples of the nonwoven fabric that can be employed here include those made of synthetic fibers made from polyethylene, polypropylene, polyester, and other thermoplastic resins. Further, as the synthetic resin film, for example, a polyethylene sheet, particularly a polyethylene sheet having micropores, or a liquid-impermeable film having moisture permeability by adding a filler to a thermoplastic resin and stretching it is preferable. When such a liquid-impervious synthetic resin film is employed, it is possible to suppress the peeling during wearing, and thus a more comfortable wearing feeling can be obtained. As the cover sheet, it is naturally possible to adopt not only liquid permeable but also liquid impermeable depending on the use form of the urine absorption pad. In this case, it is preferable to use a nonwoven fabric alone.

  Also, the skin contact sheet may be either hydrophilic or hydrophobic, but if it has hydrophilic properties, it can be expected to improve wearability to sweat, but urine will also permeate into the skin contact sheet. If anything, it can be said that it is preferable to be hydrophobic. As the skin contact sheet, a nonwoven fabric, a mesh sheet or a film made of synthetic fibers made from polyethylene, polypropylene, polyester, or other thermoplastic resin can be used. When the nonwoven fabric is adopted, a card nonwoven fabric, a spunbond nonwoven fabric, a nonwoven fabric obtained by laminating the spunbond (S) nonwoven fabric and the melt blown (M) nonwoven fabric in the form of SMS, SMMS, SMMMS, etc. are preferable.

  Any of the absorbers described above can be used as long as they are used in absorbent articles such as ordinary diapers. However, it is preferable that the absorber has a high SAP content and is thin. That is, a combination of cotton-like pulp and SAP, or a material added with heat-sealing fibers can be used, and the whole is preferably wrapped with a hydrophilic sheet such as tissue. In addition, it is also possible to use a sheet-like absorbent body such as one in which a SAP layer is formed on one side of a hydrophilic sheet or one in which SAP is sandwiched between two hydrophilic sheets.

  In the urine absorption pad according to the first aspect of the present invention, a pair of elastic members are joined in an extended state along the left and right side edge portions of the cover sheet, thereby forming gathers on the left and right side edge portions of the cover sheet. be able to. As this elastic member, a stretchable elastic member such as a natural rubber flat rubber, urethane thread, thread rubber or the like is used, and it can be bonded and fixed to the cover sheet using a hot melt adhesive or the like.

  The tethering tape can be formed of an elastic body that can be stretched along its longitudinal direction, and the elastically deformable layer can be elastically deformed as the tethering tape is stretched. As the tethering tape, a strip-shaped foam sheet such as urethane foam can be used from the viewpoint of stretchability and touch. When this urethane foam is used, the friction between the epidermis of the penis is large, so it is convenient to prevent falling off. You may paste a nonwoven fabric on the surface. In addition, natural elastic or synthetic urethane thread, thread rubber, flat rubber, etc., which is used as a stretchable elastic member used for ordinary diapers and fixed between stretched nonwoven fabrics, hot melt adhesive, etc. An adhesive sheet and a stretchable sheet, a stretchable film sandwiched between stretchable nonwoven fabrics, or a stretchable net sandwiched between stretchable nets can be used as a tethering tape.

  An anti-slip adhesive portion for releasably joining the urine absorbing pad to the inside of the lower cover to be worn can be provided on the surface portion of the cover sheet.

  According to the urine absorption pad of the present invention, an absorbent body that absorbs urine and holds the urine is provided on the back surface side of the cover sheet, and the tethering tape that is wound around the penis portion of the male genital so that both ends overlap each other The center part is joined to the back side of the cover sheet, and a pair of joining parts are provided at both ends of the tethering tape so that the overlapping parts of the tethering tape can be peeled from each other. Since the elastic deformation layer compressible in the thickness direction of the tethering tape is provided on the tethering tape, the urine absorbing pad is not bulky, and it is possible to securely tether the urine absorbing pad to the penis part with the tethering tape, The tethering tape can be placed in soft contact with the penis and the urine absorption pad is positioned against the penis without compromising the feeling of wearing. It is possible to prevent the shift.

  When a pair of elastic members are joined in a stretched state along the left and right edge portions of the cover sheet, and a gather is formed on the left and right edge portions of the cover sheet, the urine absorption pad is placed along the penis portion of the male genitalia. Can be curved naturally, and leakage of urine can be suppressed.

  When a liquid-permeable skin contact sheet is joined to the back surface of the cover sheet so as to sandwich the absorbent body, it is possible to cover the absorbent body having a poor touch with the skin contact sheet, and to improve the wearing feeling.

  When the tethering tape is formed of an elastic body that can be stretched along its longitudinal direction, and the elastically deformable layer can be elastically deformed along with the extension of the tethering tape, the clamping force on the penis part is easily adjusted. And the continuous connection of the first and second tethering tapes to the penis portion, whose state is likely to change over time, can be more reliably maintained.

  If a slip-off adhesive part for releasably bonding the urine absorbing pad to the inside of the lower cover to be worn is provided on the surface part of the cover sheet, the urine pad can be more securely held by the lower cover. The wearability can be further improved by preventing the urine pad from shifting.

  Embodiments of a urine collection bag according to the present invention will be described in detail with reference to FIGS. 1 to 3, but the present invention is not limited to these embodiments, and these may be further combined or claimed in this specification. Any change or modification included in the concept of the present invention described in the scope of the present invention can be made, and can be naturally applied to any other technique belonging to the technical idea of the present invention.

  The external appearance of the urine absorption pad according to the present embodiment is shown in FIG. 1, the development state on the opposite side is partially broken and shown in FIG. 2, and the cross-sectional structure taken along the line III-III is shown in FIG. That is, the urine absorption pad 10 in the present embodiment is joined to a rectangular vertically long cover sheet 11 having a front surface portion 11a and a back surface portion 11b along the left and right side edge portions of the cover sheet 11 in an expanded state. A pair of elastic members 13 that form gathers 12 on the left and right sides of the cover sheet 11, an absorber 14 that is provided on the back surface 11 b side of the cover sheet 11, absorbs urine and holds the urine, and this absorber 14 and the liquid-permeable skin contact sheet 15 joined to the back surface portion 11b of the cover sheet 11 so as to sandwich the pair of elastic members 13, and the center portion is joined to the back surface portion 11b side of the cover sheet 11, and both end portions are joined. A tethering tape 16 wound around the penis portion of the male genitalia indicated by a two-dot chain line in FIG. 3 so as to overlap each other, and this tethering tape 1 A pair of joints 17a, 17b that are provided at both ends of the jointing tape 16 so as to detachably join the overlapping parts of the fastening tape 16, and the fastening tape 16 is formed so as to contact the penis portion of the male genitals. The elastic deformation layer 18 compressible in the thickness direction of the tethering tape 16 and the surface portion 11a of the cover sheet 11 are provided so that the urine absorbing pad 10 can be peeled inside the underwear of a brief or diaper to be worn. The anti-slip adhesive portion 19 is provided.

  As described above, the flexible cover sheet 11 has a front surface portion 11a facing the outer side when worn, that is, a lower side such as a brief or a diaper, and a rear surface portion 11b facing the inner side, that is, the wearer side. The pair of elastic members 13 and the absorber 14 are sandwiched between the cover sheet 11 and the liquid-permeable skin contact sheet 15 joined to the back surface portion 11b, and these are integrated. Thus, the wearing feeling can be improved by joining the skin contact sheet 15 to the back surface portion 11b of the cover sheet 11 so that the male genitalia does not directly touch the absorbent body 14 or the elastic member 13 having a poor touch. . The cover sheet 11 may be liquid-impermeable or liquid-permeable depending on the usage pattern of the urine absorption pad 10, and is intended to be worn inside the cover sheet 11 as an aid for a nursing diaper in the present embodiment. Therefore, liquid-permeable ones are used. In addition, when the liquid-impermeable cover sheet 11 is employed, it is desirable that the cover sheet 11 has moisture permeability, that is, air permeability, in order to prevent the cover sheet 11 from being detached.

  The absorbent body 14 in the present embodiment is in the form of a sheet containing 50 to 95% by weight of SAP, and the surface of the base sheet 20 made of a nonwoven fabric, preferably a nonwoven fabric having bulkiness and breathability, such as a curtain coat. It is formed by applying a line coating technique and applying strip-like superabsorbent layers 21 parallel to each other along the longitudinal direction of the base sheet 20. Such an absorber 14 should have a thickness of about 1/3 or less, specifically a maximum of 2 mm, generally 1 mm or less, compared to a conventional mixed absorbent of pulp and SAP. Can do. These high absorption layers 21 contain SAP in a proportion of preferably 80 to 90%. The absorbent body 14 having such a sheet shape has a portion having only the base sheet 20 and a portion on which the high-absorption layer 21 is formed, and therefore has good urine diffusibility, and also has a conventional pulp and SAP. Therefore, it is possible to obtain a comfortable wearing feeling while minimizing the bulkiness during wearing. For this reason, it is also possible to avoid the trouble that the wearing state is recognized from the outside.

  The tethering tape 16 in the present embodiment in the form of a flexible ribbon is formed of an elastic body that can be stretched along its longitudinal direction, and has a length that allows the penis base to be wound once. The pair of joint portions 17a and 17b formed at the left and right free ends of the tethering tape 16 is constituted by a surface fastener in which one is formed on the front surface side and the other is formed on the back surface side. An elastic deformation layer 18 that is compressible in the thickness direction of the tethering tape 16 is formed on the back surface side of the tethering tape 16 except for the joint portion 17b so that the tethering tape 16 does not directly contact the male genitalia. Consideration. The elastically deformable layer 18 formed of continuous foamed resin having a surface friction higher than that of the tethering tape 16 can be elastically deformed along the longitudinal direction thereof as the tethering tape 16 is stretched. The surface is finished flat, but it is effective to form corrugations and other anti-skid effects on the penis epidermis, and the thickness is changed along the longitudinal direction of the tether tape 16. Is also possible.

  When using this urine absorbing pad 10, first, the back surface portion 11b of the urine absorbing pad 10 is overlaid on the penis portion of the male genitalia, and in this state, while winding one free end of the tethering tape 16, it is wound around the penis base portion. Tightening tape to the penis base by wrapping around the penis base while pulling the other free end and joining the joint 17b of the back surface part 11b to the joint 17a of the surface part 11a of one free end 16 is wound with the elastic deformation of the elastic deformation layer 18, and the penis is prevented from coming off from the tethering tape 16 of the urine absorbing pad 10. The gathers 12 formed on both the left and right sides of the urine absorption pad 10 regulate the relative position of the urine absorption pad 10 with respect to the penis so as to urge the deformation of the urine absorption pad 10 so as to wrap the penis. Together, reduce the chance of urine leakage. Furthermore, by wearing a lower cover such as a brief or a diaper in this state, and joining the anti-slip adhesive part 19 provided in the central part of the surface part 11a of the urine absorbing pad 10 to the inner surface of the lower cover, Misalignment between the lower exposure and the urine absorption pad 10 is reliably prevented.

  In this way, the urine absorbing pad 10 can be securely connected to the male genital wrap by winding the tether tape 16 around the penis base of the male genital in a stretched state, and the lower part of the brief or diaper to be worn can be used. An anti-slip adhesive portion 19 for releasably bonding the urine absorbing pad 10 to the inside of the mushroom is provided in the central portion of the surface portion 11a of the cover sheet 11, so that urine absorption for a worn brief or diaper is performed. It becomes possible to prevent the positional deviation of the pad 10 more reliably. For example, the penis can be prevented from coming off from the urine absorbing pad 10 even if the wearer exercises to move the hip joint violently on a bicycle or the like.
