Description

  The present invention relates to a method for manufacturing a male light incontinence pad. More specifically, it is possible to manufacture a male incontinence pad that can be suitably used as a urine pad for mild incontinence by a man who lives in daily life, with reduced waste generation, at a simple and low cost. It relates to a possible manufacturing method.

  Conventionally, a urine pad including a top sheet, a back sheet, and an absorber interposed between both sheets is known as a urine pad for infants or adults such as the elderly and the disabled. It has been.

  By using the urine pad so that the surface of the top sheet is in contact with the skin of the wearer, the urine excreted by the wearer passes through the top sheet and is absorbed and held by the absorber. The back sheet having excellent leakage prevention prevents urine from leaking to the outside.

  Although more women have mild incontinence problems, men may develop urge incontinence or overflow urinary incontinence due to enlarged prostate. Absorbent products are used in a variety of cases to absorb urine, such as functional urinary incontinence that falls short of the toilet due to decreased physical function and treatment of urine when bedridden due to illness. Yes. For example, as a urine pad specialized for men, a type in which male organs are encapsulated and used is known (for example, see Patent Document 1). Such a male urine pad is, for example, a rectangular urine pad that is molded into a triangle using an adhesive tape or the like and encased in a male genitalia, so that it is used as a disposable diaper, or simply a clothing or diaper. The contact area between urine and the wearer's skin can be reduced as compared with the urine pad used by being placed on top.

  Moreover, as a male urine pad, for example, it has an absorbent body disposed between a top sheet and a back sheet, and a flap portion along the longitudinal direction (left-right direction) on the outer side (outer edge) of the absorbent body In which a cut portion (slit) is formed at a substantially central portion in the longitudinal direction of the flap portion (see, for example, Patent Document 2), or a bag shape that has been molded in advance (see, for example, Patent Document 3) ) Has also been proposed.

  Hereinafter, the form for implementing the manufacturing method of the male light incontinence pad of this invention is demonstrated concretely, referring drawings. However, the present invention broadly encompasses a method for manufacturing a male light incontinence pad comprising the invention-specific matters, and is not limited to the following embodiments.

[1] Manufacturing method of light incontinence pads for men (first manufacturing method):
The first method for manufacturing a male light incontinence pad according to the present invention includes an absorbent main body 14 in which a plurality of sheets 18 and 20 are laminated with an absorbent body 22 sandwiched therebetween, as shown in FIGS. 2A and 2B. This is a manufacturing method for manufacturing a light incontinence pad 1a for men, in which the inner surface 32 side constitutes an absorbent surface 32a, and the absorbent surface 32a is used by being directed to the wearer's male genitalia. Here, FIG. 2A is a plan view schematically showing a male light incontinence pad manufactured by an embodiment of the method for manufacturing a male light incontinence pad (first manufacturing method) of the present invention. The folded state before use of the light incontinence pad. Moreover, FIG. 2B is a perspective view which shows the state which expanded the site | part folded of the absorptive main body which comprises the male incontinence pad for men shown to FIG. 2A.

  The male light incontinence pad 1a manufactured by one embodiment of the method for manufacturing a male light incontinence pad according to the present invention is suitable for a male who runs a daily life as a light incontinence pad for mild incontinence measures. Can be used. In particular, such a light incontinence pad for men, as shown in FIG. 2B, in at least a part of the direction (for example, the vertical direction) from one end portion 14X to the other end portion 14Y of the absorbent main body 14, A lower end that is formed with a valley fold 36 that is bent in a valley fold toward the inner surface 32 side and that maintains the valley fold state of the valley fold 36 at at least one end 36X of the valley fold 36. Since it has the junction part 38 and is comprised so that the concave space 33 may be formed by the valley fold part 36 and the lower end junction part 38 at the time of expansion | deployment use of the absorptive main body 14, a light incontinence pad is male. The shape matches the bulge of the vessel, and a good wearing feeling can be obtained.

  That is, by having the above-described valley fold portion and the lower end joint portion that maintains the valley fold state of the valley fold portion, a tack (that is, a crease-like crease) is formed on the absorbent main body. When the main body is deployed, a concave space is formed on the inner surface side of the absorbent main body. In addition, the above-mentioned “deployment use” means that the absorbent main body folded by the valley fold portion is expanded (expanded), a part of the folded state of the valley fold portion is opened, and the inner surface side of the absorbent main body is opened. To make it ready for use by the wearer. That is, the portion where the valley fold state is not maintained spreads while the valley fold state is released at the time of expansion, but the vicinity of the lower end joint portion where the valley fold state is maintained cannot be expanded because the valley fold state is not released at the time of expansion. For this reason, a difference arises in the development area, and a concave space is formed on the inner surface side of the absorbent main body (that is, the male light incontinence pad).

  When the absorbent main body (i.e., the male light incontinence pad) has such a shape, the fit is very good when it is directed to the male genitals. In particular, the light incontinence pad is spread from the testicle side to the front (front body) of the wearer by placing the light incontinence pad so that the lower end joint portion side is located on the testicle side of the wearer. Since male genitalia can be covered, a sense of incongruity when worn can be greatly reduced.

  Further, the angle formed by one side edge portion and the lower end joint portion of the absorbent main body is an obtuse angle, and the outer side of the lower end joint portion of the absorbent main body is on one side of the absorbent main body. From the edge part toward the other side edge part, the angle formed by one side edge part and the locus of the cut part is cut so that it becomes an obtuse angle, and the corner of the lower end part of the absorbent main body is oblique Because it is joined, when the absorbent main body is addressed to the wearer, it can be easily developed near the corner of the lower end, and the corner of the lower end does not protrude, so it does not get in the way and wear well A feeling can be obtained. If the lower end joint portion is 90 ° with respect to the side edge joint portion, a portion that cannot be developed at the corner of the lower end portion of the absorbent main body remains obliquely, thereby hindering the wearer's good wearing feeling.

  In the method for manufacturing a light incontinence pad for men according to the present invention, as shown in FIG. 1A, the absorbent body 50 is sandwiched by a plurality of long sheets 51 (for example, an outer sheet 51a and an inner sheet 51b) at a predetermined interval. The long sheet material 52 is prepared, and two or more of the long sheet materials 52a and 52b are overlapped so that the surfaces constituting the absorbent surface 53 face each other, and one side edge portion overlapped is formed. The step of joining along the longitudinal direction of the long sheet materials 52a and 52b to form the side edge joint portion 54, and the absorber 50 arranged at intervals in the long sheet materials 52a and 52b The lower end joint portion 55 is formed by joining portions corresponding to the lower end portion side of the obtained absorbent main body, and the outer side of the lower end joint portion 55 is cut to produce an absorbent main body 56 having a predetermined shape. A process, In the step of producing the main body 56, the lower end joint portion 55 is obtained from one side edge portion 52x of the joined long sheet material 52 constituting the absorbent main body 56 toward the center portion in the width direction. The angle α1 formed by one side edge portion 52x of the absorbent main body 56 and the lower end joint portion 55 is formed to be an obtuse angle, and the lower end joint portion 55 of the absorbent main body 56 obtained between the absorbers 50 is formed. The angle β1 formed by one side edge 52x of the absorbent main body 56 and the trajectory 57 of the cut portion from the one side edge 52x of the absorbent main body 56 toward the other side edge 52y. It cuts so that becomes an obtuse angle. In addition, an above-described outer surface sheet is a sheet | seat which comprises the outer surface side of an absorptive main body, and an above-described inner surface sheet is a sheet | seat which comprises the inner surface side of an absorptive main body.

  According to the method for manufacturing a light incontinence pad for men of the present invention, a man who operates a daily life as shown in FIGS. 2A and 2B can be suitably used as a urine pad for mild incontinence. A light incontinence pad 1a for men that can be suitably used as an extremely mild urine pad or underwear liner that will wet the underwear extremely lightly after returning the male genitalia to the underwear due to poor sharpness. The production of waste can be reduced and it can be produced easily and at low cost.

  Conventionally, as shown in FIGS. 2A and 2B, a lower end joint portion 38 is formed on one side edge portion of the absorbent main body 14, and the outer side of the lower end joint portion 38 is one side edge portion of the absorbent main body 14. When manufacturing the male light incontinence pad 1a cut so that the angle formed by the trajectory of the cut portion and the cut portion is obtuse, for example, a continuous body of an absorbent main body made of a long sheet material is produced. And it cuts and manufactures an absorptive main body individually from this elongate sheet material at a predetermined space | interval. In such a manufacturing method, there is a problem that a wasteful excess portion in which the long sheet material is not used is formed between each cut-out absorbent main body, and a large amount of waste is generated during manufacturing. In addition, for example, once a rectangular absorbent main body is cut out from a long sheet material, the end of the absorbent main body may be cut (trimmed) obliquely (that is, obtuse), and manufactured. In such cases, a lot of waste is generated. Furthermore, such a manufacturing method complicates the manufacturing process and further increases the manufacturing cost of the male light incontinence pad.

  In the method for manufacturing a light incontinence pad for men according to the present invention, in the step of manufacturing the absorbent main body so as to correspond to the outer peripheral shape of the male light incontinence pad of the final product shape, The angle formed by one side edge of the absorbent main body and the lower end joint is obtuse from the one side edge of the long sheet material to the center in the width direction. While forming, the outer side of the lower end joint portion of the absorbent main body obtained between the absorbent bodies is directed from one side edge portion of the absorbent main body to the other side edge portion, and one side edge portion of the absorbent main body And cutting so that the angle formed by the trajectory of the cut portion becomes an obtuse angle, generation of waste from the long sheet material can be reduced.

  In addition, the lower end joining part mentioned above may be continuous, may be discontinuous by several joining points, or may be joined continuously. Further, the lower end joint portion may be formed by partially providing the joint portion at a position away from the side edge joint portion.

  In addition, as a fixing method of the said lower end junction part, heat sealing, joining (compression) by embossing and a meshing gear, ultrasonic sealing, the process by a needle (needle), adhesion | attachment by a hot-melt-adhesive etc. can be mentioned. As for the method for fixing the side edge joint, as in the case of the lower end joint, heat sealing, joining by embossing or meshing gear (compression), ultrasonic sealing, processing by needle (needle), adhesion by hot melt adhesive Etc.

  As shown to FIG. 1A, since the lower end junction part 55 is formed by joining the site | part corresponding to the lower end part side of the obtained absorptive main body by predetermined width | variety, one side edge part 52x in an absorptive main body and As shown in FIG. 1B, the angle α <b> 1 formed by the lower end joint 55 is along the inner contour line 71 of the side edge joint along the inner side of the side edge joint 54 and along the inner side of the lower end joint 55. The angle (angle α1) defined by the inner angle formed by the intersection of the inner contour lines 72 of the lower end joints. In addition, the inner side outline of a side edge junction part means the straight line used as the boundary line (outline line) of the side edge junction part inside an absorptive main body, and the inner side outline line of a lower end junction part is absorptivity. It means a straight line that becomes a boundary line (contour line) of the lower end joint portion inside the main body. For example, in the case where the lower end joint portion is formed by a plurality of joint points (discontinuous joint points), the inner contour line is formed by connecting the points located on the innermost side of the respective joint points. When at least one inner contour line (boundary line) is a curve, the tangent line of the curve at the intersection is defined as the inner contour line, and the angle formed with the inner contour line (tangent line) is defined as the angle α1 described above. . Here, FIG. 1B is a process diagram in which a part of the process for producing the absorbent main body in FIG. 1A is enlarged. In FIG. 1B, the same components as those shown in FIG. 1A are denoted by the same reference numerals and description thereof is omitted.

  In the method for manufacturing a light incontinence pad for men of the present invention, as shown in FIG. 1A, the cut portion on the lower end side of one absorbent main body 56a is continuously manufactured from a long sheet material 52. It is preferable to be a cut portion on the upper end side of the other absorbent main body 56b. By configuring in this way, a light incontinence pad for men that is extremely excellent in wearing feeling can be easily manufactured without generating any waste at the lower end side and upper end side cut portions of the absorbent main body 56. can do.

  In the method for manufacturing a male light incontinence pad according to the present invention, it is preferable that the cut portion on the lower end side of the absorbent main body 56 is cut by a contour along the lower end joint portion 55. By comprising in this way, the useless part in the cutting margin of the elongate sheet material which comprises an absorptive main body becomes very few, and the manufacturing cost of the light incontinence pad for men can be reduced more.

  Hereinafter, the method for producing a male light incontinence pad of the present invention will be described in more detail. First, as shown in FIG. 1A, a long sheet material 52 is produced in which an absorbent body 50 is sandwiched between a plurality of long sheets 51 (for example, an outer sheet 51a and an inner sheet 51b) at a predetermined interval. . The absorber 50 is formed in a required size by a mat former (not shown). In FIG. 1A, the absorber 50 has a cut-out corner at the lower end portion on the side edge joint portion 54 side. This is because the corner of the absorber 50 interferes with the formation of the lower end joint portion 55 to be formed later. It is to prevent it from becoming.

  As shown in FIG. 1A, the absorbent body 50 is disposed on the outer surface sheet 51b at intervals along the flow direction X of the outer surface sheet 51b. Thereafter, the inner sheet 51a is bonded to the upper surface, the inner sheet 51a and the outer sheet 51b are directly bonded around the absorber 50, and each absorber 50 is sealed to produce a long sheet material 52. .

  In the manufacturing method of the present invention, the two long sheet materials 52a and 52b are produced in this way, the two long sheet materials 52a and 52b are overlapped, and one side edge thereof is joined. A light incontinence pad 1a for men is manufactured. That is, the two long sheet materials 52a and 52b are overlapped so that the surfaces constituting the absorbent surface 53 face each other so as to be in a state before use of the male light incontinence pad (for example, see FIG. 2A). Then, one side edge part is joined along the longitudinal direction of the long sheet materials 52a and 52b to form the side edge joined part 54. The side edge joint portion 54 can be formed by, for example, an embossing roll or the like.

  Next, a portion corresponding to the lower end side of the obtained absorbent main body between the absorbent bodies 50 arranged at intervals in the long sheet materials 52a and 52b is joined to form the lower end joined portion 55. At this time, the lower end joining portion 55 is directed from one side edge portion 52x of the joined long sheet material 52 constituting the absorbent main body 56 toward the center portion in the width direction, and one of the obtained absorbent main body 56 in the absorbent main body 56 is obtained. The angle α1 formed by the side edge portion 52x and the lower end joint portion 55 is formed to be an obtuse angle. The lower end joining portion 55 can be formed by, for example, an embossing roll or the like.

  Next, the outer side of the formed lower end joint portion 55 is cut, and an absorbent main body 56 having a predetermined shape is produced from the long sheet material 52. Under the present circumstances, between the absorbers 50, the outer side of the lower end joint part 55 of the obtained absorbent main body 56 is directed from one side edge 52x to the other side edge 52y in the absorbent main body 56, so that the absorbent main body 56 Is cut so that the angle β1 formed by one side edge portion 52x and the locus 57 of the cut portion becomes an obtuse angle. In this way, the male light incontinence pad 1a as shown in FIG. 2A can be manufactured.

  In the manufacturing method of the present invention, an angle α1 (see FIG. 1A) formed by one side edge of the absorbent main body and the lower end joint is formed to be an obtuse angle, and in the absorbent main body If the angle β1 (see FIG. 1A) formed by one side edge and the locus of the cut portion is cut so that it becomes an obtuse angle, the specific angle is not limited, but for example, the angle α1 and angle β1 are preferably 100 ° or more, and more preferably 120 ° or more. Moreover, as a maximum angle in an obtuse angle, it is preferable that it is 170 degrees or less, and it is still more preferable that it is 150 degrees or less. By comprising in this way, when an absorptive main body is addressed to a wearer, the expansion | deployment of the corner vicinity of a lower end part can be made easy, and a very favorable wearing feeling can be obtained. For example, when the angle α1 and the angle β1 are less than 100 °, there may be a portion that cannot be expanded at the corner of the lower end of the absorbent main body. On the other hand, if the angle α1 and the angle β1 exceed 170 °, minor incontinence may occur. The depth of the space formed inside the pad may become shallow. In addition, an extra sharp point may be formed at the upper end of the adjacent light incontinence pad, which may deteriorate the appearance.

  In FIG. 1A, as described above, from one side edge 52x of the absorbent main body 56 to the center in the width direction of the long sheet material 52 on which the lower end joint 55 is actually formed. The angle β1 is cut so that it becomes an obtuse angle, and thereafter, the angle formed by the locus 57 of the cut portion is about 90 degrees (that is, the other side edge portion) from the central portion to the other side edge portion 52y. The case where it cut | disconnects so that it may become perpendicular | vertical to 52y is shown. Thus, in the manufacturing method of the present invention, if the angle β1 is cut so as to become an obtuse angle in the range where the lower end joint portion 55 is actually formed, the subsequent long sheet material 52 is used. There is no restriction | limiting in particular about the locus | trajectory of cutting | disconnection of this, It can select suitably in consideration of the wearing feeling in the crotch side of the light incontinence pad for men. That is, after the range where the lower end joint portion 55 is formed, it may be cut perpendicularly to the other side edge portion 52y as shown in FIG. 1A, or straight from the range where the lower end joint portion 55 is formed. You may cut | disconnect diagonally so that the angle (beta) 1 may become an obtuse angle.

  In FIG. 1A, two long sheet materials 52a and 52b are prepared, the two long sheet materials 52a and 52b are overlapped, and one side edge thereof is joined to each other to provide a light incontinence pad for men. Although the example in the case of manufacturing la is shown, for example although illustration is omitted, the long sheet material arranged in the center part of the width direction of the male light incontinence pad, and both sides of this long sheet material ( For example, three long sheet materials are produced with two long sheet materials arranged on the left and right), and the long sheet material arranged on the right side is arranged on the long sheet material arranged on the central portion. And the long sheet material arranged on the left side is sequentially arranged, and similarly to FIG. 1A, one side edge portion where each long sheet material is superimposed is joined to form a side edge joint portion. The portion corresponding to the lower end side of the obtained absorbent main body between the absorbent bodies Combined lower joint formed, then cut the outer bottom joint, it is also possible to produce the absorbent body of predetermined shape from three sheets of the long sheet material. According to such a manufacturing method, for example, a male light incontinence pad 1b as shown in FIGS. 3A and 3B can be manufactured.

  Here, FIG. 3A is a plan view schematically showing a male light incontinence pad manufactured by another embodiment of the male light incontinence pad manufacturing method (first manufacturing method) according to the present invention. The folded state before use of the light incontinence pad. Moreover, FIG. 3B is a perspective view which shows the state which expanded the site | part folded of the absorptive main body which comprises the male incontinence pad for men shown to FIG. 3A. In FIGS. 3A and 3B, the same components as those of the male light incontinence pad 1a shown in FIGS. 2A and 2B are denoted by the same reference numerals and description thereof is omitted.

To the opposite side edge 62y, cutting is performed so that the angle β2 formed by the side edge 62x where the fold 64 of the absorbent main body 65 is formed and the locus 67 of the cutting portion becomes an obtuse angle. .

  According to the method for manufacturing a light incontinence pad for men of the present invention, as shown in FIG. 5A and FIG. 5B, a man living in daily life can be suitably used as a urine pad for mild incontinence. A light incontinence pad 1c for men that can be suitably used as an extremely mild urine pad or underwear liner that will wet the underwear extremely lightly after returning the male genitalia to the underwear due to poor sharpness. The production of waste can be reduced and it can be produced easily and at low cost.

  As described above, in the second method for manufacturing a male light incontinence pad of the present invention, the long sheet material 62 is arranged so that the surface constituting the absorbent surface 63 is on the inside. The male light incontinence pad can be manufactured by the same process as the first method for manufacturing the male light incontinence pad of the present invention described so far, except for the step of folding along the longitudinal direction.

  In the method for manufacturing a male light incontinence pad according to the present invention, as shown in FIG. 4, the cut portion on the lower end side of one absorbent main body 66 a is continuously manufactured from a long sheet material 62. It is preferable to be a cut portion on the upper end side of the other absorbent main body 66b. By constructing in this way, a light incontinence pad for men having a very excellent wearing feeling can be produced without generating any waste at the lower end side and upper end side cut portions of the absorbent main body 66. Can do.

  Moreover, in the manufacturing method of the light incontinence pad for men of this invention, it is preferable to cut | disconnect the cutting part in the lower end part side of the absorptive main body 66 by the outline along the lower end junction part 65, and to form. By comprising in this way, the useless part in the cutting margin of the elongate sheet material which comprises an absorptive main body becomes very few, and the manufacturing cost of the light incontinence pad for men can be reduced more.

[3] Male light incontinence pads:
Next, the male incontinence pad 1a shown in FIGS. 2A and 2B is further illustrated as an example of the male incontinence pad manufactured by the first manufacturing method and the second manufacturing method of the present invention described so far. This will be described in detail. A light incontinence pad 1a for men shown in FIGS. 2A and 2B includes an absorbent main body 14 in which a plurality of sheets 18 and 20 are laminated with an absorbent body 22 sandwiched therebetween, and the inner surface 32 side of the male incontinence pad is a wearer's male device. A light incontinence pad 1a for men to be used, wherein the absorbent main body 14 has an inner surface at least partially in a direction (for example, a vertical direction) from one end portion 14X to the other end portion 14Y. A valley fold portion 36 is formed that is bent in a valley fold toward the side 32, and a side edge joint portion 37 in which the valley fold portion is joined with a predetermined width along the fold of the valley fold portion 36. And a lower end joint portion 38 that maintains the valley folded state of the valley folded portion 36 at at least one end portion 36X of the valley folded portion 36, and when the absorbent main body 14 is used for deployment, the inner surface 32 side A concave space 33 is formed in Is constructed sea urchin.

[3-1] Absorbent body:
The light incontinence pad 1a for men shown to FIG. 2A and FIG. 2B is equipped with the absorptive main body 14 as a member which bears the function to absorb and hold | maintain the urine which the wearer excreted. This absorptive main body 14 is formed by laminating a plurality of sheets with the absorber sandwiched therebetween, and as shown in FIGS. 2A and 2B, so as to cover the absorber 22 and the inner surface of the absorber 22. The disposed inner sheet 18 and the outer sheet 20 disposed so as to cover the outer surface of the absorber 22 are included as constituent elements, and the absorber 22 is sandwiched between the inner sheet 18 and the outer sheet 20. A member fixed in a state and integrated into a pad shape can be exemplified.

  The above "inner surface of the absorber" refers to a surface located on the skin side of the wearer when the light incontinence pad for men is worn. On the other hand, the above "external surface of the absorber" When a light incontinence pad is worn, it refers to the surface located on the wearer's clothing side.

  In addition, the absorbent main body used for the light incontinence pad for men may be configured by folding (folding) a sheet-shaped absorbent main body by a valley fold (second folding). (Manufacturing method), a plurality of absorptive main bodies may be integrally formed by joining the valley folds as a boundary (first manufacturing method).

[3-1a] Inner surface sheet:
An inner surface sheet is a sheet | seat arrange | positioned on the surface located in a wearer's skin side. For this reason, it is preferable that at least a part of the inner surface sheet is constituted by a liquid-permeable sheet. By comprising in this way, urine can permeate | transmit a liquid-permeable sheet | seat, reaches | attains an absorber rapidly, and can be absorbed and hold | maintained. In addition, as long as at least one part is comprised with the liquid-permeable sheet, the whole inner surface sheet does not necessarily need to be comprised with the liquid-permeable sheet. As long as the liquid-permeable sheet is a sheet having liquid permeability, the material of the sheet is not particularly limited, and examples thereof include a woven fabric, a nonwoven fabric, and a porous film.

  In addition, as a more suitable example of an inner surface sheet, a liquid-permeable nonwoven fabric can be mentioned. By using such a liquid-permeable nonwoven fabric, the touch is good and the smoothness of the surface after liquid absorption can be improved.

[3-1b] Outer sheet:
An outer surface sheet is a sheet | seat arrange | positioned on the surface located in a wearer's clothing side. The outer sheet is a liquid-impermeable sheet that does not allow urine to pass through to prevent urine absorbed by the absorber from leaking to the outside of the absorbent main body, or it does not easily pass through urine, but can be transmitted by applying pressure. It is preferable that the liquid low permeability sheet is used.

  As the liquid impervious sheet described above, a polyethylene film used for general absorbent products can be cited as a preferred example. Such polyethylene films include a moisture permeable polyethylene film and a non-moisture permeable polyethylene film, and any film can be used as an outer sheet, but a moisture permeable polyethylene film can be more suitably used. By using such a moisture-permeable polyethylene film as an outer sheet, stuffiness is reduced during wearing, and comfort when wearing a light incontinence pad can be improved.

  Moreover, as a liquid low-permeability sheet | seat mentioned above, a nonwoven fabric with a high water pressure resistance can be mentioned as a suitable example. As the nonwoven fabric with high water pressure resistance, for example, nonwoven fabrics such as SMS (spunbond / meltblown / spunbond) and SMMS (spunbond / meltblown / meltblown / spunbond) are preferable.

  Since these non-woven fabrics are obtained by accumulating and bonding hydrophobic synthetic fibers, urine may be repelled, but urine may pass if pressure is applied. However, when a male incontinence pad is used as a light incontinence pad for mild incontinence by men who operate daily life, the amount of urine at the time of incontinence is small. Even so, it can be sufficiently used as an outer sheet. Thereby, air permeability can be further improved as compared with the case where the above-described polyethylene film is used, and the comfort when the light incontinence pad is worn can be further improved.

  The water pressure resistance is a numerical value representing the performance (waterproofness) that suppresses the force applied to the moisture that tries to soak into the fabric constituting the sheet. For example, it conforms to JIS L 1092 water resistance test A method. It can be measured by the method. In the light incontinence pad for men of the present invention, the water pressure resistance is 40 mmAq. The above nonwoven fabrics can be mentioned, and the water pressure resistance is 100 mmAq. The above nonwoven fabric can be used suitably.

  Furthermore, you may use the sheet | seat which laminated | stacked the said polyethylene film and the said nonwoven fabric with high water pressure resistance as an outer surface sheet. By configuring in this way, it is difficult for the wearer to rub around the outer sheet and the underwear of the wearer when touching or touching the outer sheet when replacing the light incontinence pad for men or during wearing. It can be worn safely without worrying about eyes and ears.

[3-1c] Absorber:
The absorber used for the general absorbent product can be used as the absorber. For example, as an absorbent material constituting the absorber, fluff pulp obtained by pulverizing wood pulp into a cotton shape and a highly water-absorbing resin (hereinafter sometimes referred to as “SAP”) can be cited as preferred examples.

  In addition, in order to wrap the said absorber as needed, you may have further the water absorbent paper and the nonwoven fabric which performed the hydrophilic treatment. That is, it may be an absorbent body in which an absorbent material containing fluff pulp and SAP is wrapped with the above water-absorbing paper or a non-woven fabric subjected to hydrophilic treatment.

  In addition, in light incontinence pads for men, the absorbent body does not require a large amount of absorption if it is intended for light incontinence applications and can handle a very small amount of water absorption. In order to meet these needs, the absorbent body and one of the sheets sandwiching the absorbent body may be configured integrally. For example, by directly fixing SAP on the above-described SMS nonwoven fabric or SMMS nonwoven fabric, and further covering the surface with the above absorbent paper or nonwoven fabric for wrapping, the absorbent body and the back sheet are integrated, and one sheet having both functions It may be used as a water absorbing sheet. An SAP sheet in which only SAP is sandwiched between hydrophilic nonwoven fabrics can also be used.

[3-2] Valley fold, and lower end joint for maintaining valley fold state:
The absorbent main body 14 constituting the male light incontinence pad 1a shown in FIGS. 2A and 2B is formed with a valley fold 36 that is bent in a valley fold toward the inner surface 32 side of the absorbent main body 14. At least one end of the valley fold 36 has a lower end joint 38 that maintains the valley fold state of the valley fold 36. A concave space 33 is formed on the inner surface 32 side.

  The said valley fold part is formed so that a crease | fold may be arrange | positioned along a wearer's up-down direction, when an absorptive main body is addressed to a wearer. In addition, in this specification, when an absorptive main body is addressed to a wearer, the direction used as a wearer's up-down direction may be called the vertical direction of an absorptive main body.

  The light incontinence pad for men manufactured by the method for manufacturing a light incontinence pad for men of the present invention is not limited to one (one) valley fold, and a plurality of light incontinence pads may be provided. That is, the valley folds may be formed at two locations, one on each side across the width direction center of the male light incontinence pad, or at three locations in the width direction of the male light incontinence pad. Three valley folds may be formed. Of course, there may be one valley fold. In such a light incontinence pad for men, the lower end joint part that maintains the valley folded state is formed at at least one end of each valley folded part.

  In addition, since the shape (surface shape) of the absorbent main body becomes multifaceted by forming multiple valley folds on the absorbent main body, it is possible to further improve the fit of light incontinence pads for men It becomes.

  If the lower end joint for maintaining the valley folded state of the valley folded portion is, for example, capable of fixing the inner side surfaces of the absorbent main body and maintaining a part of the valley folded state, There are no restrictions on the fixing method. Examples of the fixing method include heat sealing, joining (compression) using embossing or a meshing gear, ultrasonic sealing, processing using a needle (needle), adhesion using a hot melt adhesive, and the like.

[3-3] Side edge joint portion:
As shown in FIG. 2A, the absorbent main body constituting the male light incontinence pad of the present invention has a side edge joint portion 37 in which the valley fold portion is joined with a predetermined width along the fold of the valley fold portion 36. Have. This side edge joint portion is formed by joining the side edges of two long sheet materials at the time of manufacture. By forming such a side edge joint portion 37, the strength of the sheet constituting the absorbent main body 14 is partially improved, the absorbent main body 14 can be stretched along the valley folding direction, and the developed absorbent The main body 14 is less likely to lose its shape. In the second manufacturing method of manufacturing a light incontinence pad for men by folding a single long sheet material, such a side edge joint portion is not formed. After folding, the folds can be further joined to form a side edge joint.

  The male incontinence pad manufacturing method of the present invention can manufacture a male incontinence pad for incontinence measures easily and at low cost by reducing the generation of waste. Light incontinence for men that can be suitably used as an extremely mild urine pad or underwear liner that will wet the underwear extremely lightly, especially after returning the male genitalia to the underwear due to poor urination The pad can be manufactured easily and at low cost with less waste generation.
