Description

  The present invention relates to a male urine pad that includes a top sheet, a back sheet, and an absorbent body interposed between a part of both sheets and encapsulates a male genitalia.

  Conventionally, a disposable diaper provided with a top sheet, a back sheet, and an absorbent body interposed between a part of both sheets as an absorbent article for infants or adults such as the elderly and the disabled Urine pads are widely used. And the male urine pad of the type which encloses and uses a male genitalia is known as an absorbent article specialized for men (for example, refer patent document 1). This male urine pad is an absorbent article provided with a top sheet, a back sheet and an absorbent body, similar to conventional disposable diapers and urine pads. It is characterized in that it is encapsulated and used.

For example, a male urine pad 100 shown in FIG. 1 includes a top sheet 2, a back sheet 4, and an absorbent body 6 interposed in a part between both sheets. An adhesive portion 8 for mounting is formed on the surface. Such a male urine pad 100 is addressed from the lower side of the male genitalia 18 so that the upper edge 10 thereof is on the near side (the wearer's body side), and along the straight lines L ₁ and L ₂ , After the right edge 12 and the left edge 14 are turned back to the center side of the pad, the adhesive portion 8 is used in a state of being fixed to the topsheet 2 on the left edge 14 side. By doing so, the male urine pad 100 has a cone shape (sack shape) with the upper end edge 10 side as an opening and the lower end edge 16 side as an apex, so that the male genitalia 18 can be encapsulated.

  Since the male urine pad as described above is used in a state that the male genitalia is encapsulated, compared with a disposable diaper, or a urine pad that is simply placed on the underwear or diaper, the excrement and the skin of the wearer The contact area can be reduced. Therefore, there is an advantage that skin troubles caused by excrement can be reduced.

  However, the male urine pad as described above has a problem that the urine pad is likely to be displaced or detached from the male genitalia due to the wearer's movement or the like, which may cause urine leakage. Therefore, various methods have been proposed in order to prevent the urine pad from shifting or coming off which causes urine leakage.

  For example, it has an absorber disposed between a top sheet and a back sheet, and a flap portion is formed on the outer side (outer edge) of the absorber along the longitudinal direction (left-right direction). The length of the flap portion A male urine pad in which a cut portion (slit) is formed at a substantially central portion in the direction has been proposed (see, for example, Patent Document 2).

JP-A-8-280727 (paragraph 0003, FIG. 1) JP 2001-129002 (paragraph 0007, FIG. 1)

  The male urine pad described in Patent Document 2 can be inserted so as to penetrate the male genital from the back sheet side to the top sheet side of the urine pad by forming a slit. According to such a urine pad, since the male genitalia are sandwiched by the slits, the effect of fixing the urine pad to the male genitalia is higher than in the case where the male genitals are simply encapsulated with the urine pad. It can be expected to prevent the pad from shifting or coming off.

  However, although the male urine pad described in Patent Document 2 has a certain effect in terms of preventing the urine pad from being displaced or detached, the effect has not reached a sufficiently satisfactory level. In addition, when the wearer excretes a large amount of urine at a time, the urine may leak from the slit to the outside of the urine pad. Furthermore, since the male genitals are pressed in an unnatural form at the slit, a comfortable wearing feeling was not obtained. That is, the male urine pad described in Patent Document 2 has room for improvement in terms of fixing effect on male genitalia, urine leakage from the slit portion, and wearing feeling, and still has problems to be solved.

  The present invention has been made to solve such problems of the prior art, has a high fixing effect on male genitalia, can effectively prevent urine leakage from the slit, and is comfortable to wear. The present invention provides a male urine pad that can provide a feeling.

  As a result of intensive studies to solve the problems of the prior art as described above, the inventor formed a three-dimensional flap having a free end and a fixed end along the upper edge of the urine pad, and formed a slit or a The present invention has been completed by conceiving that the above problem can be solved by arranging perforations that can become slits by breakage. Specifically, the following male urine pads are provided by the present invention.

[1] A male urine pad including a top sheet, a back sheet, and an absorbent body interposed between a part of the two sheets and encapsulating a male genitalia, the free end and the fixed end A urine pad for men is formed along the upper edge of the urine pad, and at least one selected from the group of perforations that can form slits by slits and breaks is disposed in the three-dimensional flap .

[2] The male urine pad according to [1], wherein the three-dimensional flap is formed of a sheet material separate from the top sheet and the back sheet.

[3] The male urine pad according to [1] or [2], wherein a three-dimensional flap stretchable material is disposed along the slit and / or the perforation.

[4] The male urine pad according to any one of [1] to [3], wherein an adhesive portion for wearing is further formed on the outer surface of the back sheet.

[5] The male urine pad according to any one of [1] to [3], which is formed in a bag shape having the upper edge side as an opening.

  The male urine pad of the present invention has a high fixing effect on male genitalia, can effectively prevent urine leakage from the slit, and can provide a comfortable wearing feeling.

  Hereinafter, the best mode for carrying out the male urine pad of the present invention will be specifically described with reference to the drawings. However, the present invention broadly encompasses male urine pads having the invention-specific matters, and is not limited to the following embodiments. In addition, about FIG.6 and FIG.8, for the convenience of drawing, drawing was performed in the form which excluded the solid flap elastic material and the solid gather elastic material from the drawing.

[1] Configuration of the present invention:
In the male urine pad of the present invention, for example, like the male urine pad 1 shown in FIGS. 2 and 3, the three-dimensional flap 24 having the free end 40 and the fixed end 42 extends along the upper edge 10 of the urine pad. The slit 22 is formed in the three-dimensional flap 24 formed. As shown in FIG. 4, the male urine pad 1 is used by being inserted into a slit 22 disposed in a three-dimensional flap 24 so as to penetrate a male genitalia 18. The male urine pad of the present invention has the following effects.

1) Since the slit is disposed in the three-dimensional flap that is flexible and easily deformed, even if the wearer moves, the three-dimensional flap, which is a fixed part of the male genitalia, deforms following the movement of the wearer. Therefore, the urine pad is not easily displaced or detached due to the wearer's movement, and the effect of fixing the male genitalia is high. On the other hand, when the slit is arranged in the flap part (“upper flap” referred to in the present specification) like the male urine pad described in Patent Document 2, the upper flap is poor in flexibility and is difficult to be deformed. As the person moves, the urine pad often deviates from or disengages from the male genitalia, and the fixation effect on the male genitalia may be insufficient. The reason why the upper flap is inflexible and difficult to deform is that the upper flap is a rigid structure having a laminated structure of a top sheet and a back sheet, and is adjacent to a relatively thick absorber. Is due to.

2) Since the slit is disposed on the three-dimensional flap that stands up from the absorption surface of the urine pad (upper surface of the top sheet), even if the wearer excretes a large amount of urine at one time, the urine is blocked by the standing surface of the three-dimensional flap. Therefore, the leak-proof property is high even for a large amount of urine, and the effect of effectively preventing leakage of urine from the slit is achieved. On the other hand, when a slit is disposed on the upper flap as in the male urine pad described in Patent Document 2, the slit is disposed on the same surface as the absorption surface of the urine pad. Therefore, if the wearer excretes a large amount of urine at a time, the urine may travel down the absorption surface and reach the slit, and may pass through the slit and leak outside the urine pad.

3) Since the slit is arranged on the three-dimensional flap that stands up from the absorption surface of the urine pad (the upper surface of the top sheet), the male genitalia is substantially perpendicular to the three-dimensional flap, that is, substantially parallel to the absorption surface of the urine pad. Can be inserted. Therefore, the male genitalia is less likely to be pressed in an unnatural state, and a comfortable wearing feeling can be obtained. On the other hand, when a slit is disposed in the upper flap as in the male urine pad described in Patent Document 2, the male genitalia is inserted in a direction substantially orthogonal to the upper flap and, consequently, the absorption surface of the urine pad. Therefore, if the male genital is intended to be directed to the absorbing surface, the male genital is pressed in an unnatural shape at the slit, and a comfortable wearing feeling is often not obtained.

  The male urine pad of the present invention has a characteristic configuration in which a three-dimensional flap is formed. In the present specification, a portion of the urine pad where the absorber is not disposed is referred to as a “flap”, and a flap having a free end and a fixed end is referred to as a “three-dimensional flap”. For example, in the case of the male urine pad 1 shown in FIGS. 2 and 3, the three-dimensional flap 24 having the free end 40 on the lower end edge 16 side and the fixed end 42 on the upper end edge 10 side is formed.

  In the male urine pad of the present invention, the three-dimensional flap is disposed at least along the upper edge of the urine pad. Since the male urine pad is generally configured in a rectangular shape as a whole, a strip-shaped three-dimensional flap is formed so as to be parallel to the upper edge 10 of the urine pad, like the male urine pad 1 shown in FIGS. A configuration in which 24 is arranged is common.

  The position where the three-dimensional flap is arranged is not particularly limited as long as it is along the upper edge of the urine pad, but a general arrangement is such that the fixed end is located on the upper flap of the urine pad. For example, in the case of the male urine pad 1 shown in FIGS. 2 and 3, the absorbent body 6 is arranged at the center of the rectangular urine pad, and the upper edge 10 side so as to surround the absorbent body 6. The upper flap 20 is formed on the lower end edge 16, the lower flap 28 is formed on the right edge 12, the right flap 30 is formed on the right edge 12, the left flap 32 is formed on the left edge 14, and the fixed flap 42 is positioned on the upper flap 20. Is arranged.

  It is sufficient that the three-dimensional flap has at least a length capable of forming a slit. However, like the male urine pad 1 shown in FIGS. 2 and 3, the three-dimensional flap 24 has a width of the urine pad (the urine pad width). It may be formed in a length equivalent to the length between the left and right side edges). Such a form has the advantage of facilitating continuous manufacture of the urine pad.

  The height of the three-dimensional flap is preferably 5 to 80 mm, and more preferably 10 to 50 mm. By setting the thickness to 5 mm or more, a sufficient leak-proof effect can be ensured, and mechanical strength can be ensured even when slits are formed. On the other hand, by setting it as 80 mm or less, it is possible to prevent the problem that the male flap is covered without the solid flap rising.

  The three-dimensional flap may be an overturned flap that tilts toward the outer edge side (upper edge side) from the center side of the urine pad, but from the outer edge side (upper edge side) of the urine pad from the viewpoint of improving leakage prevention. It is preferably an inward-turning flap that tilts toward the center side. For example, the male urine pad 1 shown in FIG. 2 and FIG. 3 is an example in which the three-dimensional flap 24 is turned over to make it a flap. Moreover, it is good also as a three-dimensional flap (C fold flap, Z fold flap, etc.) which formed the bending part and the folding | turning part in a part of height direction.

  In the male urine pad of the present invention, at least one selected from the group of perforations that can form slits by slits and breaks is disposed on the three-dimensional flap as described above. In other words, either one or both of the slit and the perforation are arranged.

  For example, as in the case of the male urine pad 60 shown in FIG. 5, the same effect as the slit can be obtained when the perforation 26 that can form the slit by breaking is formed instead of the slit. In this way, when the perforation is formed instead of the slit, the length of the slit can be adjusted according to the degree of breakage, so it is possible to form a slit with a length that matches the size of the wearer's male genitals It becomes. Accordingly, there is an advantage that the fixing effect on the male genitalia is further improved as compared with the case where the slit is formed. In addition, as an example in which both the slit and the perforation are arranged, there is a configuration in which the central portion is a slit and both side edges are perforated.

  There are no particular restrictions on the positions at which the slits and perforations (hereinafter sometimes referred to as “slits and the like”) are placed as long as they are on the three-dimensional flap. In the male urine pad of the present invention, since the three-dimensional flap is often formed in a strip shape, a configuration in which slits and the like are arranged so as to be parallel to both the free end and the fixed end is common. For example, the male urine pad 1 shown in FIGS. 2 and 3 is arranged at the center in the longitudinal direction (left-right direction) of the urine pad so as to be parallel to the free end 40 and the fixed end 42 of the strip-shaped three-dimensional flap 24. This is an example in which a slit 22 is arranged.

  There is no restriction | limiting in particular also about lengths, such as a slit, What is necessary is just to determine suitably in consideration of the size of a wearer's male genitalia. However, in order to insert male genitalia, it is preferably 20 mm or more, and more preferably 30 mm or more. On the other hand, in order to securely fix the male genitalia, it is preferably 100 mm or less, and more preferably 80 mm or less.

  In the male urine pad of the present invention, it is preferable to arrange a three-dimensional flap stretchable material along the slit or the like. By doing so, an appropriate stretching force acts on the slit portion, so that the male genitalia sandwiched by the slit can be more reliably fixed. Moreover, since a favorable fixing effect is obtained regardless of the size of the wearer's male genitals, the male genitals can be used particularly suitably for the elderly and disabled persons who often atrophy.

  The arrangement method of the three-dimensional flap elastic material is not particularly limited as long as it is arranged along the slit or the like, but normally, a configuration in which the three-dimensional flap elastic material is arranged so as to be parallel to the slit or the like is adopted. For example, the male urine pad 1 shown in FIGS. 2 and 3 is an example in which two three-dimensional flap elastic members 34 a and 34 b are arranged so as to be parallel to the slit 22.

  There is no restriction | limiting in particular about the arrangement position of a three-dimensional flap elastic material, You may arrange | position to the free end side of a three-dimensional flap, may arrange | position to the fixed end (standing line) of a three-dimensional flap, and freedom of a three-dimensional flap You may arrange | position between an end and a fixed end (a bending part, a folding | turning part, etc. of a C fold gather or a Z fold gather). Moreover, as long as it follows a slit etc., there is no restriction | limiting in particular also about the number and length of a three-dimensional flap elastic material. For example, the male urine pad 1 shown in FIGS. 2 and 3 is an example in which the free end side of the three-dimensional flap 24 is folded, and two three-dimensional flap elastic members 34a and 34b are arranged at the folded portion.

  In the male urine pad of the present invention, it is also preferable to dispose a three-dimensional flap stretchable material on both sides such as a slit. By doing so, since the stretching force acts on the entire outer periphery of the slit, it is possible to further improve the fixing effect of the male genitalia.

[2] Specific embodiment of male urine pad:
The male urine pad of the present invention is provided with a top sheet, a back sheet, and an absorber interposed in a part between both sheets. This male urine pad can be assembled using an adhesive portion (hereinafter referred to as an “assembled urine pad”) or a pre-formed bag (hereinafter referred to as “bag-shaped”). It will be roughly classified into “urine pad”. The configuration of the male urine pad of the present invention can be applied to both an assembled urine pad and a bag-shaped urine pad.

[2-1] Assembled urine pad:
The male urine pads 1 and 60 shown in FIGS. 2 to 5 which have already been described are assembled urine pads. For example, the male urine pad 1 shown in FIGS. 2 and 3 includes a top sheet 2, a back sheet 4, and an absorbent body 6 interposed in a part between both sheets, and further the back sheet. A pressure-sensitive adhesive portion 8 for mounting is formed on the surface of 4. The adhesive portion 8 is usually covered with a release liner, and is configured so that the release liner can be peeled off during use to expose the adhesive portion. The adhesive part can be easily formed by a method such as attaching a release liner coated with an adhesive.

When the male urine pad 1 shown in FIGS. 2 and 3 is used, as shown in FIG. 4, the male urine pad 18 is placed so that the upper edge 10 is on the front side (the wearer's body side). The male device 18 is inserted through the slit 22 formed in the three-dimensional flap 24. Then, after the right edge 12 and the left edge 14 of the pad are folded back toward the center of the pad along the straight lines L ₁ and L ₂ , the adhesive portion 8 is used while being fixed to the surface sheet 2 on the left edge 14 side. . By doing so, the male urine pad 1 has a cone shape (sack shape) with the upper end edge 10 side as an opening and the lower end edge 16 side as an apex, so that the male genitalia 18 can be encapsulated.

[2-2] Bag-like urine pad:
The bag-like urine pad is not assembled using the adhesive part, but is a bag-like shape whose opening is the upper edge side (upper flap side) of the urine pad in advance by joining the edges of the urine pad. It is configured. Such a bag-like urine pad does not require assembling work and has an advantage that it can be used easily.

  For example, after folding a urine pad having the same configuration as the assembled urine pad so that the right edge and the left edge overlap, the upper edge of the urine pad is joined in advance by joining the right edge, the left edge, and the lower edge. It can comprise in the bag shape which uses an edge side (upper flap side) as an opening part. In addition, when forming the above joining parts, it is not necessary to arrange | position a surface sheet about the parts (lower end edge, right side edge, left side edge, etc. of a urine pad) used as a joining part.

  When using the pouch-shaped urine pad, the male genital is inserted into the bag through the opening so that the opening on the upper edge side is on the near side (the wearer's body side). At this time, it is inserted and fixed so as to pass through a slit formed in the three-dimensional flap. Since the bag-shaped urine pad is configured in a bag shape in advance, the male genitalia can be encapsulated.

  In addition, the male urine pad (bag-like urine pad) of the present invention as described above has an opening on the upper edge side of the urine pad in addition to the slit which is the insertion part of the male genitals formed in the three-dimensional flap. Will be formed. This opening can be used to insert a hand into the bag-shaped urine pad and pull out the male genitals when it is difficult to insert the male genitals through a slit formed in the three-dimensional flap. Since the opening is formed on the top edge side, there is little possibility of urine leakage from there, but an adhesive fastener or mechanical fastener is attached near the opening and the opening is sealed after fixing the male genitalia You may make it do.

[2-3] Adhesive part:
As already described, in the case of an assembly-type urine pad, it is preferable that an adhesive portion for mounting is formed. The urine pads 1 and 60 for men shown in FIGS. 2 to 5 are those in which the adhesive portion 8 for wearing is formed on the surface on the back sheet 4 side, but naturally formed on the surface on the top sheet 2 side. It is included in the scope of the male urine pad of the present invention.

  Moreover, although the male urine pad 1,60 shown in FIGS. 2-5 has only the adhesion part 8 for mounting | wearing as an adhesion part, in addition to this, a urine pad is used with respect to an underwear or a disposable diaper. You may form the adhesion part for fixation for fixing. That is, in the male urine pad of the present invention, two or more adhesive portions may be formed. By forming such an adhesive part, displacement and detachment of the urine pad due to the wearer's movement or the like are effectively prevented. About the adhesion part for fixation, the structure similar to the adhesion part for mounting | wearing is employable.

[3] Components of male urine pad:
The male urine pad of the present invention includes a top sheet, a back sheet, an absorbent body and a three-dimensional flap as essential components, and may include other components depending on the purpose. Hereinafter, these components will be described.

[3-1] Top sheet:
A surface sheet is a sheet | seat arrange | positioned at a contact surface side with a wearer's skin. Since the top sheet needs to absorb the wearer's urine and body fluid in the absorber disposed on the lower surface side, at least in the vicinity of the top surface of the absorber, the top sheet is liquid permeable so that the wearer's urine and body fluid can permeate. Consists of materials. In other words, as long as the vicinity of the upper surface of the absorber is made of a liquid-permeable material, the entire surface sheet does not necessarily need to be made of a liquid-permeable material.

  For example, it is also preferable that the central portion of the urine pad is made of a liquid-permeable material and the outer edge portions (the vicinity of the upper edge, the right edge, the left edge and the lower edge) are made of a water-repellent material. It is. Such a configuration is preferable because it can suppress leakage of urine from the outer edge of the urine pad. However, from the viewpoint of reducing the number of constituent members and simplifying the manufacturing process, it is preferable to configure the entire top sheet with a liquid-permeable material.

  Examples of the liquid permeable material constituting the surface sheet include a woven fabric, a nonwoven fabric, and a porous film. Especially, it is preferable that it is the nonwoven fabric comprised from the synthetic fiber. Examples of the synthetic fiber include resins composed of components such as polypropylene, polyethylene, polyester, nylon, etc., and may be a single fiber composed of only one of these components, or composed of two or more components. It may be a composite fiber. Of these, polyester / polypropylene, polyester / polyethylene, and polypropylene / polyethylene composite fibers are preferred because of their high strength. There is no restriction | limiting in particular also about the kind of nonwoven fabric, The conventionally well-known nonwoven fabric manufactured by various manufacturing methods, such as air through (card hot air), card | curd embossing, and a spun bond, can be used suitably.

[3-2] Back sheet:
A back sheet is a sheet | seat arrange | positioned at a contact surface side with a wearer's clothes. Since the back sheet needs to prevent the wearer's urine and body fluid from leaking outside the urine pad, at least the vicinity of the lower surface of the absorber is made of a liquid-impermeable material. However, from the viewpoint of reducing the number of constituent members and simplifying the manufacturing process, the entire back sheet is generally made of a liquid-impermeable material.

  Examples of the liquid-impermeable material constituting the back sheet include a liquid-impermeable film made of a synthetic resin such as polyethylene. Moreover, in order to prevent the inside of a diaper from being steamed, it is also one of the preferable forms to use a liquid-impermeable film with moisture permeability. Examples of the liquid-impermeable film with moisture permeability include a microporous polyethylene film produced by adding a filler such as calcium carbonate to a polyethylene resin, kneading, extruding, and then stretching. . This microporous polyethylene film is a water-repellent sheet that has a large number of fine pores of 0.1 to several μm and allows moisture and gas to pass therethrough but does not allow water to pass within the water pressure resistance.

  Note that a sheet made of a material different from that of the back sheet may be bonded to the back surface sheet (hereinafter, such a sheet will be referred to as a “cover sheet”). By this cover sheet, the touch (tactile feeling) of the urine pad can be improved, and the effect of reducing discomfort when the back sheet comes into contact with the wearer's skin can be obtained. In particular, the urine pad for men is different from the urine pad used by placing it on underwear or diapers, and such a form is preferable because the back sheet comes into contact with the wearer's skin during use. Examples of the material constituting the cover sheet include woven fabric and non-woven fabric. Among these, dry nonwoven fabrics and wet nonwoven fabrics made of thermoplastic resins such as polyethylene, polypropylene, and polyester can be suitably used.

[3-3] Absorber:
The absorber is a member for absorbing and holding the wearer's urine and body fluid, and is interposed in a part between the two sheets described above (that is, the top sheet and the back sheet). Usually, an absorber is interposed in the center part of the front sheet and the back sheet configured in a rectangular shape, and an upper flap, a lower flap, a right flap, and a left flap are formed so as to surround the absorber. The absorbent body is made of an absorbent material because it needs to absorb and hold the wearer's urine and body fluid.

  Examples of the absorbent material constituting the absorbent body include disposable diapers and other conventionally known absorbent materials commonly used in other absorbent articles, such as fluff pulp (cotton pulp), super absorbent polymer (Super Absorbent Polymer). Hereinafter referred to as “SAP”), hydrophilic sheets and the like.

As the fluff pulp, for example, a pulp sheet having a fiber length of 5 mm or less can be suitably used by defibrating a pulp sheet with a pulverizer. The pulp sheet used at this time may be a chemical pulp sheet or a mechanical pulp sheet, and the pulp raw material is not particularly limited as long as it is used as a normal pulp raw material, such as softwood, hardwood, straw, bamboo, kenaf, waste paper, etc. Can be used. The amount of fluff pulp used is generally 50 to 400 g / m ² , although it varies depending on the structure of the absorber.

  As SAPs, starch-based, cellulose-based, and synthetic resin-based SAPs are known, and any of these may be used. Specifically, starch-acrylic acid (salt) graft copolymer, saponified starch-ethyl acrylate graft copolymer, saponified starch-methyl methacrylate graft copolymer, starch-acrylonitrile graft copolymer Saponified product of starch, acrylamide saponified graft copolymer, polyacrylic acid (salt), polyethylene oxide crosslinked with acrylic acid, crosslinked product of sodium carboxymethyl cellulose, crosslinked product of polyvinyl alcohol-maleic anhydride Can be used. Among these, it is preferable to use sodium polyacrylate having a high absorption performance capable of absorbing water 20 times or more of its own weight.

Examples of the hydrophilic sheet include tissue, absorbent paper, and non-woven fabric subjected to hydrophilic treatment. Especially, it is preferable to use the thing in the range whose basic weight is 10-30 g / m < ² >.

  These absorbent materials are usually used as a single-layer or multi-layer mat. Under the present circumstances, 1 type may be used independently among the said absorptive materials, and 2 or more types may be used together. Among these, those mainly composed of fluff pulp and combined with SAP are preferable. At this time, the SAP may be uniformly mixed in each mat of fluff pulp, or may be arranged in layers between the layers of the multilayer fluff pulp. The amount of SAP is preferably 10 to 500 parts by mass and more preferably 15 to 300 parts by mass with respect to 100 parts by mass of the dried fluff pulp. By using such an amount, the SAP particles can minimize mutual interference, so that the particles do not form a permeation barrier, and can transmit and absorb urine and body fluid in a three-dimensional direction. It becomes possible.

  In addition, in the male urine pad of this invention, it is preferable to set it as the structure which wraps the whole absorber with a hydrophilic sheet. Such a configuration has an advantage that SAP can be prevented from leaking from the absorber and shape stability can be imparted to the absorber.

  As for the shape of the absorbent body, in addition to a rectangular shape like the absorbent body 6 of the male urine pad 1 shown in FIG. 2 and FIG. Any shape can be adopted as long as it is used.

  However, in the male urine pad of the present invention, it is preferable to use the absorbent body having a notch. Examples of the absorber having a notch include U-shaped absorbers in addition to the hourglass shape described above.

  For example, the male urine pad 70 shown in FIGS. 6 and 7 is an example in which an hourglass-type absorber 50 is used as the absorber 6. The “hourglass-type absorber” is an absorber in which notches are formed on two opposing sides of a rectangular absorber, and the entire shape is constricted. In the case of using an hourglass-type absorbent body, as shown in FIG. 6, it is preferable to arrange the notch portions so as to face the upper edge 10 side and the lower edge 16 side of the urine pad.

  The portion where the absorbent body of the urine pad is disposed has a relatively high rigidity and the deformation of the urine pad is easily restrained, but the hourglass-type absorbent body can reduce the rigidity at the notch portion of the absorbent body. . Therefore, as shown in FIG. 6, when the hourglass-type absorber 50 is arranged so that the notch portions thereof face the upper edge 10 side and the lower edge 16 side of the urine pad, the three-dimensional flap 24 and the three-dimensional gather 46 are notched. Since it rises in the form of biting into the part, the height of the three-dimensional flap 24 and the three-dimensional gather 46 can be earned by the amount of the notch, and the leak-proof property of the urine pad can be improved.

  Further, the male urine pad 80 shown in FIGS. 8 and 9 is an example in which the U-shaped absorbent body 52 is used as the absorbent body 6. The “U-shaped absorber” is an absorber in which a cutout is formed on one side of a rectangular absorber. When using the U-shaped absorbent body, as shown in FIG. 8, the cutout portion is disposed so as to face the upper edge 10 side of the urine pad, that is, at a position corresponding to the insertion portion of the male genitalia. It is preferable to arrange. By adopting such a configuration, it is possible to obtain favorable effects such as improvement of the fixing effect on male genitalia, reduction of an extra flap area, improvement of urine pad attachment, and increase in the amount of absorbent loaded (absorption capacity increase). .

  In addition, you may arrange | position the sheet | seat for diffusing liquids, such as urine and a bodily fluid, incidentally on the upper surface side (for example, between an absorber and a surface sheet) to an absorber. In the present specification, such a sheet is particularly referred to as a “second sheet”. When this second sheet is attached, due to the wearer's posture, etc., even when the space on the lower surface side of the topsheet is not sufficiently formed, the absorption rate of urine, body fluid, etc. is difficult to decrease, and the absorption rate decreases. It is possible to prevent leakage of urine and body fluids.

  Examples of the material constituting the second sheet include hydrophilic and liquid-permeable materials such as woven fabric, non-woven fabric, porous plastic, and fluff pulp. Examples of these constituent materials include polypropylene, polyethylene, polyester, rayon, pulp, and composite fibers thereof. As the pulp, crimped fibers such as curly cellulose fibers can be suitably used.

[3-4] Solid flap:
The three-dimensional flap may be formed by folding back the front sheet or the back sheet in whole or in part. However, the top sheet is often made of a hydrophilic material, and it is difficult to impart leakproofness to the three-dimensional flap, and when the free end side portion of the three-dimensional flap is formed by the back sheet, the entire three-dimensional flap It may become hard and feel pain when it comes into contact with the wearer's skin.

  Therefore, it is preferable that the three-dimensional flap is constituted by the folded portion of the back sheet and the sheet material by a method of folding the back sheet and further bonding the sheet material to the folded portion. For example, in the male urine pad 70 shown in FIGS. 6 and 7 and the male urine pad 80 shown in FIGS. 8 and 9, the back sheet 4 is folded back on the upper edge 10 side of the urine pad, and a sheet material is further added to the folded portion. This is an example in which the three-dimensional flap 24 is configured by the folded portion of the back sheet 4 and the sheet material 44a by the method of bonding 44a. Such a form can ensure the flexibility of the entire three-dimensional flap by a method such as selecting a flexible material such as a nonwoven fabric as the sheet material to be bonded, and the upper edge side of the urine pad by the folded portion of the back sheet There is an advantage that it is possible to prevent bleeding of urine from the urine. In addition, when employ | adopting such a structure, it is preferable to adhere the above-mentioned cover sheet to a back surface sheet.

  Further, the three-dimensional flap may be formed of a sheet material separate from the top sheet and the back sheet. Such a form can form a three-dimensional flap which is rich in flexibility and excellent in leakproofness by a method such as selecting a water-repellent nonwoven fabric as a sheet material. That is, the three-dimensional flap can be configured with a material that meets the required performance. Such a configuration also has an advantage that continuous production is easy. For example, the male urine pad 1 shown in FIGS. 2 and 3 forms a three-dimensional flap 24 by bonding a sheet material 44 a separate from the top sheet 2 and the back sheet 4 to the top sheet 2 and the back sheet 4. This is an example.

  As a material constituting the three-dimensional flap, it is preferable to use a water-repellent material in order to improve leakage resistance. Non-woven fabrics such as spunbond and card embossing can be used as the water repellent material, but SMS (spunbond / meltblown / spunbond), SMMS (spunbond / meltblown / meltblown / It is preferable to use a nonwoven fabric such as spunbond. Alternatively, a liquid-impermeable material obtained by bonding a plastic film to a liquid-permeable material or a water-repellent material may be used.

  In order to enhance the leak-proof property of the three-dimensional flap, it is preferable that both side edges are fixed to the topsheet 2 or the like by the fixing portion 36 as in the male urine pad 1 shown in FIG. The fixing method is not particularly limited, but may be fixed by an adhesive such as a hot melt adhesive, welding, or other means.

[3-5] Solid gather:
Since the male urine pad of the present invention has a three-dimensional flap at least on the upper edge side, an elastic material can be provided on the three-dimensional flap to provide a three-dimensional gathering effect. It is also a preferred form that a three-dimensional gather is formed so as to surround at least a part of the edge, the left edge, and the lower edge. In particular, it is preferable to form a three-dimensional gather along the lower edge of the urine pad because leakage of urine from the outer edge of the urine pad can be suppressed. For example, in the male urine pad 70 shown in FIGS. 6 and 7, the three-dimensional flaps 24a and 34b are arranged on the three-dimensional flap 24 to give the effect as a three-dimensional gather, and then the lower edge 16 side of the urine pad. In this example, the three-dimensional gather 46 is formed.

  The structure of a three-dimensional gather can employ | adopt the structure normally used for the conventional disposable diaper and other absorbent articles. For example, a stretchable material (three-dimensional gather stretchable material) is arranged on a part of the belt-shaped sheet material, and a gather (rib) is formed on the sheet material by the stretchable material, and the like is used as the three-dimensional gather. Further, a three-dimensional gather may be configured by the folded portion of the top sheet or the back sheet and the sheet material by a method of folding the top sheet or the back sheet and further attaching a sheet material to the folded portion. For example, in the male urine pad 70 shown in FIGS. 6 and 7, the back sheet 4 is folded back on the lower edge 16 side of the urine pad, the sheet material 44b is further bonded to the folded portion, and the free end of the sheet material 44b is further bonded. This is an example in which the three-dimensional gather 46 is configured by a method of folding the side and sandwiching a three-dimensional gather elastic material 48 in the folded portion.

  As the material constituting the sheet material, it is preferable to use the water-repellent material exemplified in the section of the surface sheet. However, a liquid-impermeable material obtained by bonding a plastic film to a liquid-permeable material or a water-repellent material may be used. The height of the three-dimensional gather is generally about 10 to 50 mm. About the constituent material, shape, etc. of a three-dimensional gather stretchable material, the structure similar to a three-dimensional flap stretchable material is employable.

[3-6] Three-dimensional flap elastic material:
As the three-dimensional flap stretchable material, it is preferable to use a material having an elongation ratio in the range of 130 to 500% when the non-stretched state is 100%, and a material having an elongation ratio in the range of 200 to 300%. Is more preferable. By using a material having an elongation rate in the range of 130 to 500%, the three-dimensional flap stretchable material can expand and contract following the movement of the wearer. Therefore, it becomes difficult to form a gap around the male genitalia, improving the fixing effect of the male genitalia and effectively preventing urine leakage from around the male genitalia.

  On the other hand, when a material having an elongation rate of less than 130% is used, the elastic force of the three-dimensional flap stretchable material tends to be insufficient, so that a gap is easily formed around the male genitalia. When inserting, it becomes difficult to fully open the slit, and it may be difficult to attach the urine pad. In addition, when a material with an elongation rate exceeding 500% is used, not only the slit is reduced more than necessary, but it becomes difficult to attach the urine pad, and the male genitals of the wearer are tightened too much, so the skin becomes red. There is a risk of skin troubles such as becoming.

  As long as these conditions are satisfied, the constituent material and shape are not particularly limited. For example, thread rubber or flat rubber made of an elastic material such as natural rubber or synthetic rubber (urethane rubber, etc.), stretchable film, or foam A urethane sheet etc. can be mentioned. For example, the male urine pad 80 shown in FIGS. 8 and 9 is an example in which a urethane foam sheet 54 is used as the three-dimensional flap elastic material 34. In this example, in order to prevent the foamed urethane sheet 54 from being peeled off, the foamed urethane sheet 54 is disposed between the back sheet 4 and the sheet material 44a.

  Among the constituent materials, thread rubber or flat rubber is preferable. The thickness of the rubber thread is preferably 310-3730 dtex, more preferably 470-1240 dtex. The flat rubber preferably has a width of 0.5 to 5.0 mm, more preferably 0.8 to 3.0 mm. The thickness of the flat rubber is preferably 0.1 to 1.0 mm, more preferably 0.2 to 0.5 mm. When using a plurality of three-dimensional flap stretchable materials, the thickness, elongation ratio, etc. may be set as appropriate within the above range according to the purpose, and it is not necessary to use the same materials.

  Usually, the three-dimensional flap elastic material is fixed to the back sheet or the like by an adhesive or other means. As a fixing method, for example, a hot melt adhesive, starch-based or water-soluble glue such as carboxymethylcellulose (CMC), and other adhesives with high fluidity may be used. It may be welded by sound waves or the like.

  In addition, the male urine pad of the present invention may be provided with an elastic material other than the three-dimensional flap elastic material (hereinafter referred to as “pad elastic material”). For example, in the male urine pad 1 shown in FIGS. 2 and 3, two pad stretch members 38a and 38b are arranged along the lower end edge 16 of the urine pad, and along the upper end edge 10 of the urine pad, 1 This is an example in which a pad stretchable material 38c is disposed. Since such a structure is gathered by the pad stretch material, when the urine pad is assembled in a cone shape (sack shape), it is possible to effectively prevent urine leakage from the joint portion. Is preferable.

  About a constituent material, a shape, etc. of a pad elastic material, the structure similar to a solid flap elastic material can be employ | adopted. Moreover, there is no restriction | limiting in particular about the number, arrangement position, length, etc. of a pad elastic material, The structure according to the objective can be employ | adopted.

[4] Manufacturing method:
Hereinafter, an example of the method for producing the male urine pad of the present invention will be described with reference to an example of continuously producing the male urine pad 1 shown in FIG. Such a male urine pad is manufactured from a “urine pad continuum” having a structure in which a plurality of male urine pads 1 shown in FIG. 2 are continuously arranged in the vertical direction of the drawing. Can do. Hereinafter, description will be given with reference to FIG.

  First, a long sheet material (three-dimensional flap material) to be the three-dimensional flap 24 of the urine pad is created. The three-dimensional flap material is created by folding a long sheet material along the longitudinal direction, pasting the folded flap material 34a, 34b between the folded portions, and then forming the slits 22 intermittently. can do. This three-dimensional flap material is integrated with the surface sheet material by being bonded to the end of a long sheet material (surface sheet material) to be the surface sheet 2.

  Next, a plurality of absorbent bodies 6 wrapped in a hydrophilic sheet are intermittently disposed on the upper surface of a long sheet material (back surface sheet material) to be the back sheet 4 along the longitudinal direction of the back sheet material. At the same time, the pad stretch members 38a, 38b, and 38c are continuously arranged. Furthermore, the top sheet material is arranged on the upper surface so that the integrated three-dimensional flap material is located on the upper edge side of the urine pad continuum, and the periphery of each absorber is placed on the back sheet material and the top sheet material (integrated) The upper flap 20, the lower flap 28, the right flap 30, and the left flap 32. By doing so, it is possible to obtain a continuous urine pad in which a plurality of urine pads are continuously arranged in the longitudinal direction.

  Furthermore, the adhesive portion 8 is intermittently formed by applying an adhesive to a long release liner and sticking it to a predetermined position on the surface of the back sheet material while cutting it at a predetermined length. Finally, the urine pad continuum is separated at the gaps between the plurality of absorbent bodies 6 (portions corresponding to the right flap 30 and the left flap 32) to obtain a plurality of individually separated male urine pads 1. In this manner, a plurality of male urine pads 1 including the top sheet 2, the back sheet 4, and the absorbent body 6 interposed between the two sheets can be obtained.

  The male urine pad according to the present invention can be used as a urine pad for infants or adults such as elderly people and persons with disabilities who need care. And since the male urine pad of this invention has high leak-proof property also with respect to a lot of urine, it can be used suitably as a urine pad for adults with much urine output. Moreover, since the fixing effect with respect to a male genitalia is high, it can use especially suitably for the elderly person with a disability, etc. with whom a male genital is often atrophied.
