However, since the light incontinence pad for men disclosed in Patent Document 1 is intended for urine leakage caused by illness or aging, emphasis is placed on reliably capturing leaked urine and processing at the time of disposal. There is much room for improvement in terms of actual usability and wearability that will be worn with pants on.
In addition, many men who are healthy men and young men have residual urine attached to the pants during daily use, and the attached part turns yellow, or the residual urine seeps into the pants and feels embarrassed. Has experienced. However, a sheet for absorbing residual urine for men targeting such a small amount of residual urine has not yet appeared on the market.

In order to solve the above problems, an embodiment of a sheet including a sheet body attached to the inner surface of a front portion of a male undergarment according to the present invention to absorb residual urine, the sheet body is bonded to the back surface It is characterized by comprising a grip part in which no part is formed.
Preferably, the grip portion is a protruding portion protruding from an upper edge of the sheet main body.

Preferably, at least one of an upper edge or a lower edge of the seat body is provided with a positioning portion for positioning the seat body with respect to the underwear.
Preferably, the positioning part is a linear part extending in parallel with the horizontal axis direction.

Preferably, the lower portion of the seat body is formed in a tapered shape so that the width becomes narrower downward.
Further, preferably, depending on the type of the undergarment, the sheet body can be attached to the undergarment with the upper edge or lower edge of the seat body arranged upward.

Preferably, the color of the surface on the user side of the sheet main body is a black or gray achromatic color or a chromatic color having lightness equivalent to the achromatic color.
Preferably, the color of the user-side surface of the sheet body is a gray achromatic color from No. 1 to No. 6 in the Munsell color system.

According to the present invention, when the seat body is attached to the inner surface of the front part of the underpants as male underwear, the grip portion can be held by hand, so that the usability during attachment is improved.

[Basic configuration]
Hereinafter, based on Example 1 shown in FIG. 1 thru | or FIG. 8, and Example 2 shown in FIG. 9 thru | or FIG. 11, the structure of the sheet | seat 1 which concerns on this invention, its effect | action, and an effect are demonstrated.
First, a basic configuration common to the seat 1 according to the present invention including the first and second embodiments will be described.

In FIG. 1, a sheet 1 is a sheet for detachably attaching to a front inner surface of a pant P as male underwear when used to absorb residual urine. The sheet 1 may be a disposable type. As shown in FIG. 1, the sheet main body 9 constituting the sheet 1 may have a substantially rectangular shape including a shoulder portion 17 processed into a round shape and a tapered portion 19 whose width is narrowed downward at the lower portion of the sheet 1. .
The outer dimensions of the sheet main body 9 excluding the grip portion 31 described later are, for example, a width W of about 105 mm and a length H of about 125 mm, and the width W ranges from 50 mm to 150 mm depending on the size of the pants P. Thus, the length H can be adjusted in the range of 100 mm to 180 mm.
The sheet body 9 includes, for example, a liquid-permeable surface sheet 3 addressed to the user's crotch (male genitals) during use, and residual urine that has entered from the front surface of the surface sheet 3 as shown in the cross-sectional view of FIG. Absorbent liquid 5 for absorbing U, and impervious liquid applied to the inner surface of the front part of the pants P in order to prevent the residual urine U absorbed by the absorbent sheet 5 from adhering to the pants P The back sheet 7 having the properties may be laminated in order.

  As shown in FIG. 2, an adhesive portion 13 for attaching the sheet body 9 to the inner surface of the front portion of the pants P is formed on the back surface of the back sheet 7. The adhesion part 13 is formed by apply | coating an adhesive, for example. As shown in FIG. 3, a covering sheet 11 having peelability may be attached to the adhesive portion 13 so as to cover the back surface of the back sheet 7.

  The material of the top sheet 3 is preferably a material having softness and soft contact with the skin, and woven fabrics, knitted fabrics, nonwoven fabrics, pulp products, etc. using natural fibers or synthetic fibers can be used. Uses synthetic fibers made by blending rayon and polyester. Moreover, as the structure of the surface sheet 3, it can be configured in a mesh shape or embossed on the surface. When such a structure is adopted, the liquid permeability of the residual urine U is improved. In addition, wearability is improved by reducing the contact area with the skin.

Moreover, as a material of the absorbent sheet 5, a composite fiber in which the surface of a cellulose-based natural fiber such as cotton or pulp having excellent liquid absorbability is covered with a synthetic fiber such as polyethylene, polyester, or polypropylene can be used. In addition, the synthetic fibers such as polyethylene, polyester, and polypropylene are excellent in heat sealability and are excellent in dryness that prevents the stickiness of the surface.
Moreover, the blending ratio of the natural fiber and the synthetic fiber can be blended at a ratio of 3: 7 to 7: 3 by weight ratio, and 4: 6 to 6 when it is desired to improve the feel and wearing feeling. : The said natural material and synthetic fiber are mix | blended in the ratio of 4.

Moreover, as a material of the back sheet 7, for example, materials such as polyethylene, polyester, polyvinyl alcohol, polypropylene, nylon, cellophane, vinylon, and vinyl chloride, which are excellent in liquid impermeability, can be used. If an inorganic material such as calcium carbonate powder is kneaded and then biaxially stretched, unpleasant sensation due to stuffiness or the like can be reduced.
Moreover, it is also possible to use what was uniaxially stretched without using an inorganic substance such as calcium carbonate. In this case, it is possible to reliably prevent the residual urine U from flowing out to the pants P side. . In the following examples, the thickness of the back sheet 7 is set in the range of 10 to 50 μm in order to reduce the uncomfortable feeling at the time of mounting and ensure the necessary liquid impermeability.

Further, as the pressure-sensitive adhesive forming the adhesive part 13, water-soluble adhesives such as acrylic water-soluble adhesives and water-insoluble adhesives such as rubber hot melts and olefin hot melts can be used, preferably pants. A water-insoluble adhesive such as a rubber-based hot melt having an appropriate adhesive strength that does not cause twisting or misalignment when applied to P and an appropriate elasticity that does not restrict the elongation of the pants P is used.
Moreover, as a peel force which shows the adhesive strength of the said adhesive, the range of 80-500gf is practical, Preferably the adhesive whose peel force is 100-300gf is used. Incidentally, when the peel force is less than 80 gf, the adhesive strength is weakened and the sheet body 9 is likely to be twisted, displaced, or dropped. On the other hand, when the peel force exceeds 500 gf, an adhesive residue is generated on the pants P.

Moreover, as a material of the covering sheet 11, a release layer provided with a solvent-type or solvent-free type silicone resin or the like is provided on one surface of paper as a base material through a sealing layer formed of polyethylene or the like. Paper can be used as an example.
Next, the characteristic configuration, the operation, and the effect of the sheet 1 according to the present invention will be described using the above-described Example 1 and Example 2 as examples.

Further, the second bending guide portion 23 may be formed as a relatively small constricted portion 25B constricted in a semicircular shape at or near the center of the lower edge 27 of the sheet body 9.

  When a force that folds the sheet main body 9 is applied, the sheet main body 9 bends with a straight line L1 along the horizontal axis direction X connecting the center of the constricted portion 25A as the first bending guide portion 21 as a folding line. . In addition, two generally along the longitudinal direction Y connecting the constricted portion 25B as the second bending guide portion 23 and both end portions 31a of the grip portion 31 provided at the center portion of the upper edge 29 of the sheet main body 9. The sheet body 9 bends with the straight lines L2 and L2 as folding lines.

Further, the first fold guide portion 21 and the second fold guide portion 23 are provided with slits 33 having predetermined lengths provided at predetermined positions on both sides and the lower portion of the sheet body 9 shown in FIG. A groove 35 having a predetermined length extending along the straight lines L1 and L2 shown in FIG.
Further, as shown in FIG. 6 (c), the first folding guide portion 21 and the second folding guide portion 23 are provided with perforated slits or the like so as to be easier to bend than other portions. The weakened structure 37 may be configured at a predetermined position of the sheet main body 9 by reducing the hardness difference or the thickness.

By adopting the bending guide structure configured in this way, the seat body 9 bends following the movement of the daily body sitting on the chair, standing, bending the waist, and twisting, A feeling of wearing improves.
Moreover, since it follows also the operation | movement which bends and lowers the front upper part of the underpants P at the time of small use, it contributes also to the improvement of usability. Further, since the approximate position of the center of gravity G of the sheet body 9 can be grasped from the first bending guide portion 21 and the second bending guide portion 23, it also functions as a sticking guide structure described below.

(2) Adhering Guide Structure In FIG. 1, a grip portion 31 having an arc shape as an example is formed at the center of the upper edge 29 of the sheet body 9 so as to protrude upward. It is preferable that the bonding portion 13 is not provided on the back surface of the back sheet 7 of the grip portion 31.
The upper edge 29 of the sheet body 9 is constituted by a straight line portion 39A extending in parallel with the horizontal axis direction X. The straight line portion 39A is arranged in parallel to the line of the rubber cord 41 (see FIG. 5) on the upper part of the pant P when the sheet main body 9 is affixed to the inner surface of the front part of the pant P. It functions as a positioning part 43A for determining the position. Of course, the seat body 9 may be positioned by positioning the positioning portion 43A along the line of the rubber cord 41 or by determining the relative position of the positioning portion 43A with respect to other portions of the pants P by a predetermined method.

Further, a linear portion 39B extending in parallel with the horizontal axis direction X is also formed on the lower edge 27 of the seat body 9. The straight line portion 39B functions as a positioning portion 43B that serves as a mark when correcting the inclination or the like of the sheet body 9 when the sheet body 9 is affixed to the inner surface of the front portion of the pants P. The positioning portion 43 may have other configurations such as a marker or a color as a mark.
Moreover, the taper part 19 formed in the lower part of the sheet | seat main body 9 of the opening parts 45 and 45 for putting out the leg provided in the right and left of the crotch part in brief type underpants P2 shown in FIG.5 (b). You may comprise at the angle matched with the inclination.

The types of pants P worn by men include the boxer-type pants P1 shown in FIG. 5 (a), the brief-type pants P2 shown in FIG. 5 (b), and the trunks type shown in FIG. 5 (c). Pants P3. In the boxer-type pants P1 and the brief-type pants P2, since the adhesion can be relatively secured, the male genitalia often faces upward when worn. Moreover, it is assumed that there are many cases where the upper portions of the pants P1 and P2 are bent forward when used for small use. Therefore, by sticking the sheet 1 to the pants P1 and P2 with the gripping portion 31 (upper edge 29) arranged upward so that the upper area can be widely covered as shown in the figure, the sheet 1 absorbs residual urine from leakage. It can be prevented more effectively.
On the other hand, when the seat body 9 is affixed to the loose trunks-type pants P3 shown in FIG. 5 (c), since the adhesion by the pants P3 cannot be expected so much, the male genitals face down when worn. There are many. In addition, it is assumed that the openings 45 and 45 of the pants P3 are used for small use. Therefore, as shown in the figure, the seat 1 is arranged upside down as in the case of the above-described pants P1 and P2, that is, with the grip portion 31 (upper edge 29) arranged downward, so that the lower area can be covered widely. By sticking to the pants P3, it is possible to more effectively prevent residual urine from being absorbed by the sheet 1.

When the sticking guide structure configured as described above is adopted, when the sheet main body 9 is stuck on the inner surface of the front part of the pants P with the pants P worn, the gripping part in which the adhesive part 13 is not formed. Since 31 can be attached by hand, the usability at the time of application is improved. Further, since the area that can be covered by the sheet main body 9 can be enlarged by the grip portion 31, leakage of the residual urine U can be reduced.
Further, the positioning positions 43A and 43B provided on the upper edge 29 and the lower edge 27 of the sheet main body 9 can correct the attaching position and the inclination of the sheet main body 9, and the right and left openings of the pants P can be provided by providing the tapered portion 19. It is possible to prevent the sheet main body 9 from being displaced or dropped, or the sheet main body 9 from being twisted or wrinkled due to the protrusion of the sheet main body 9 from 45 or 45 or from the lower corner portion of the sheet main body 9.

(3) Cover Sheet Dividing Structure and Adhesive Arrangement Structure As shown in FIG. 2, the adhesive portion 13 formed on the back surface of the back sheet 7 has a plurality of stages (for example, two rows on the left and right, and four on the top and bottom) It may be arranged regularly over. A non-adhesive part 15 having an adhesive force weaker than the adhesive force of the adhesive part 13 between the adhesive parts 13 adjacent in the vertical axis direction or the horizontal axis direction, that is, having no adhesive force or weakened adhesive force. May be arranged regularly. As shown in FIG. 3, the covering sheet 11 includes two covering sheet pieces 47 and 47 that are vertically divided into two along the longitudinal axis direction Y.

  In addition, the non-bonding portion 15 may be provided at a position corresponding to at least one of the first bending guide portion 21 and the second bending guide portion 23 (the straight lines L1 and L2 as bending curves) described above. Good (see FIG. 1). As shown in FIG. 2, the dimensions of the adhesive portion 13 </ b> A disposed in the upper two stages of the sheet body 9 and the adhesive portion 13 </ b> B disposed in the lower two stages are the same shape so as to match the shape of the sheet body 9. Not necessarily. Note that the adhesive may not be applied to the portion of the back sheet 7 corresponding to the position of the dividing line that bisects the peripheral portion of the back sheet 7 and the cover sheet 11.

  In the embodiment shown in FIG. 2, the dimensions of the adhesive portion 13A arranged in the upper two steps are set to a width of 39 mm and a height of about 23 mm, and the dimensions of the adhesive portion 13B arranged in the lower two steps. Is set to a width of about 25 mm and a height of about 23 mm. The adhesive portion 13A arranged in the upper two steps is separated by a gap S of about 1 mm, the same width as the adhesive portion 13B is about 25 mm, the height is about 23 mm, and the width is about 14 mm. Is composed of an adhesive portion of about 23 mm. The bonding portion 13A may be configured as an integrated bonding portion.

A non-adhesive portion 15A in the vertical axis direction having a width of about 13 mm is formed between the left and right rows of the adhesive portions 13, and a horizontal height of about 6 mm is provided between each of the upper and lower four-level adhesive portions 13. A non-adhesive portion 15B in the axial direction is formed. Further, as described above, the back surface of the back sheet 7 on which the grip portion 31 is provided, the outer side space of the lower two-step adhesive portion 13B, and the peripheral edge of the back surface of the back sheet 7 are non-adhesive portions. 15 is formed.
The dimensions of the adhesive portions 13A and 13B and the non-adhesive portions 15A and 15B can be appropriately adjusted in accordance with the outer dimensions of the sheet main body 9, the purpose of use, and the like. The number of parts 15 can be increased or decreased as appropriate.

When the vertically divided two-part structure of the covering sheet 11 configured as described above and the regular arrangement structure of the adhesive portion 13 and the non-adhesive portion 15 are employed, as shown in FIG. 9 is used as an adhesive part for temporary fixing, and after temporarily fixing the sheet main body 9 using the adhesive part 13A, put hands in the left and right openings 45, 45 of the pants P. The left and right covering sheet pieces 47 and 47 can be pulled out obliquely downward, and the usability at the time of sticking is improved.
In addition, since the adhesive portion 13 and the non-adhesive portion 15 are regularly arranged, the wrinkles of the sheet main body 9 become constant, and the followability to the movement of the user is further improved. Further, the non-bonding portion 15 also functions as the bending guide portions 21 and 23 described above.

(4) Color structure of surface sheet In this embodiment, the color structure of the surface sheet 3 is used in order to make it difficult to notice that the sheet 1 is stuck by a nearby person when adding a small amount of money when going out. Is adopted. The color of the surface on the user side of the top sheet 3 is a black or gray achromatic color. The color of the top sheet 3 may be a chromatic color having lightness equivalent to that of the achromatic color (for example, close to an achromatic color).

Specifically, black or gray except for white 10 in the 11-stage Munsell color system of 0 to 10 shown in FIG. 8A, preferably gray 1 to 6 Use achromatic colors or chromatic colors with similar brightness (eg, close to achromatic colors).
When the color structure of the top sheet 3 configured as described above is adopted, it is difficult for others to notice that the sheet 1 is pasted assimilating the shadow inside the pants P. Also, white is the same color used in sanitary products and diapers, and there is a sense of resistance when used. However, if the color is the same as the above gray or achromatic color, the resistance is reduced and it is easy to use. Become. In addition, these colors are colors that make stains, dirt, yellowing, etc. made by the residual urine U inconspicuous, and are colors that make an image of charcoal with a deodorizing effect. Demonstrate the effect of improvement.

Next, the contents and results of the color sensory evaluation test of the surface sheet 3 carried out in order to confirm the effect when the color structure of the surface sheet 3 is adopted will be described.
In this color sensory evaluation test, as shown in FIG. 8 (a), there is a surface sheet 3 to which 11 achromatic colors (gray tones) having different brightness from 0th to 10th in the Munsell color system are applied. A sample of sheet 1 was prepared, and an adult male as a test subject actually applied a sample to which the above 11 colors were applied to pants P, and sensory evaluation of the color was performed. The test subjects consisted of 10 users of trunks pants P and 10 users of boxer type pants P. The pants worn by the test subjects were used as pants P as they were. The average value of the upper limit value and the lower limit value of the Munsell color system selected by the test subject as the “level that he / she wants to use” and “the level that is not easily noticeable” was rounded off to obtain the evaluation result.

  As a result of the above test, as shown in FIG. 8 (b), the pants P having an eye structure composed of achromatic colors from No. 0 to No. 8 of the Munsell color system are evaluated as “I want to use”. The pants P having a color structure composed of achromatic colors up to No. 6 were evaluated as “not easily noticeable”. In the figure, “I want to use” means that it is within an acceptable range (preferable range) of colors that may be used by the user, and “Unremarkable” means that the user wants to use among the above-mentioned things that he wants to use. Indicates that it is more inconspicuous (more preferable range).

[how to use]
Next, a procedure for sticking the sheet 1A according to the first embodiment will be described with reference to FIGS.
When the sheet 1A is pasted on the pants P before being worn, the cover sheet 11 on the back surface of the back sheet 7 is peeled off, and the sheet main body 9 is stuck on the inner surface of the front portion of the pants P. At this time, the user uses the positioning portions 43A and 43B formed by the linear portions 39 provided on the upper edge 29 and the lower edge 27 of the seat body 9 to change the position and angle as shown in FIG. The sheet body 9 can be pasted at a predetermined position while checking.
Moreover, as above-mentioned, the sheet | seat main body 9 can be affixed changing a vertical direction suitably according to the kind of pants P to wear (refer FIG. 5).

  When the sheet 1A is pasted on the pants P with the pants P worn, the upper edge of the covering sheet 11 covering the upper first-stage adhesive portion 13 as shown in FIG. As shown in FIG. 7B, the front part of the pants P is pushed forward with one hand. Hold the grip portion 31 with the other hand, put the sheet 1A into the pants P, and place the straight portions 39 of the upper edge 29 to the lower edge 27 of the sheet body 9 as the positioning portions 43A and 43B of the rubber cord 41 of the pants P. It arrange | positions in parallel with a line and positions with respect to the underpants P of the sheet | seat 1A. Of course, the seat 1A is positioned by setting the straight portion 39 along the line of the rubber cord 41 or by determining the relative position of the straight portion 39 (positioning portions 43A, 43B) with respect to other portions of the pants P by a predetermined method. May be.

  Subsequently, as shown in FIG. 7 (c), the upper portion of the outer surface of the front portion of the pants P is pressed with one hand to temporarily fix the seat body 9, and the left and right openings 45, 45 of the pants P are held with the other hand. After putting the hand and pulling out the left and right covering sheet pieces 47 and 47 respectively obliquely downward as described above, the entire sticking part of the sheet body 9 is pressed from the outer surface of the front part of the pants P. In this way, the sheet 1A can be smoothly pasted even when the pants P are worn.

[Example 2]
The sheet 1B according to Example 2 basically includes all the configurations of the sheet 1A according to Example 1 described above, and further adopts a three-dimensional structure with excellent followability as a configuration unique to the present example. .
Therefore, the description of the configuration common to the first embodiment is omitted, and the three-dimensional structure unique to the present embodiment will be mainly described. In addition, about the structure which is common in Example 1 of the sheet | seat 1B which concerns on Example 2, the same code | symbol as Example 1 is used.

(5) Three-dimensional structure In FIG. 9, along the longitudinal axis Y as shown in FIG. 9 instead of the constricted portion 25B of the first embodiment described above, at the center of the lower edge 27 with respect to the sheet body 9 described above. A extending cut portion 49 is formed.
When the sheet main body 9 is affixed to the inner surface of the front portion of the pants P, the cut portion 49 is overlapped by bending the flap pieces 51 and 51 formed on the left and right sides of the cut portion 49 backward as shown in FIG. By combining, it acts to function as a three-dimensional simple container 53 having a space A for capturing the residual urine U flowing downward.

In addition, this three-dimensional structure has the rigidity of the flap piece 51 produced by bending the left and right flap pieces 51, 51 of the cut portion 49 of the seat body 9 in a backward direction, and the pants P in the pants P. It is maintained by the pressure applied by trousers or the like worn on the outside, and the amount of overlap of the left and right flap pieces 51, 51 changes following the movement of the user's body.
In order to exert such a function, it is preferable to set the shape and length of the cut portion 49 to a predetermined shape or length as described in detail below.

  The notch 49 is formed by an inverted V-shaped notch 55. The length B in the vertical direction Y from the lower edge 27 of the sheet body 9 of the notch 55 may be 40% or less of the length H in the vertical direction Y excluding the grip portion 31 of the sheet body 9. More preferably, it may be 30% or less. The maximum width D of the lower end portion of the notch 55 may be 50% or less of the length E in the horizontal axis direction X of the lower edge 27 of the sheet body 9, and more preferably 30% or less.

  The left and right flap pieces 51, 51 are tapered so as to be narrowed downward as shown in the figure, and the length E in the horizontal axis direction X of the lower edge 27 of the seat body 9 is larger than the width dimension W of the seat body 9. May be smaller. The position of the taper-shaped starting point C of the left and right flap pieces 51, 51 may be provided higher than the position of the front end portion 55 a of the notch 55. Of the back surface of the back sheet 7 of the flap pieces 51, 51, the portion below the tip 55 a of the notch 55 is not formed with the bonding portion 13 as shown in FIG. May be.

Moreover, when providing the 1st bending guide part 21 extended in the horizontal axis direction X like a present Example, it is notched rather than the straight line L1 used as the bending curve formed by the 1st bending guide part 21. The position of the front end portion 55a of 55 may be arranged below so that the function of the bending guide structure by the first bending guide portion 21 is not impaired.
In addition, the formation aspect of the said notch part 49 and the flap piece 51 is not restricted to the formation aspect shown to FIG.

May be formed. In this case, it is preferable that the adhesive strength of the adhesive portion 13 </ b> C be weaker than the adhesive strength of the other adhesive portions 13.

  When the sheet 1B according to the second embodiment is applied to the inner surface of the front portion of the pants P, a three-dimensional process by adding the flap pieces 51 described above is added, but other procedures are the same as those of the first embodiment described above. It is. Even if the flap pieces 51 described above are superimposed on the pants P before wearing, the three-dimensional structure cannot be maintained after wearing. Therefore, the three-dimensional process is performed after wearing.

In addition, when the three-dimensional structure configured in this way is adopted, a cut portion is formed in a part of the seat body 9 for the trunks-type pants P3 that are worried about leakage of the residual urine U. The simple container 53 is formed by overlapping the left and right flap pieces 51, 51 with a simple configuration that only forms 49, and the space A in the simple container 53 prevents leakage of the residual urine U downward. It becomes possible.
Further, the simple container 53 is formed by the rigidity of the flap pieces 51 and 51 generated by overlapping the left and right flap pieces 51 and 51 as described above, and the pressure applied by the pants P in the pants P and the pants worn on the outside thereof. Since the three-dimensional shape is maintained, the remaining urine U is captured while changing the overlap amount of the flap pieces 51 and 51 following the movement of the user's body without restricting the movement of the user's body. It will be.
The notches 49 may be formed at a plurality of locations below the sheet body 9 (for example, two locations so that the lower edge 27 of the sheet body 9 is roughly divided into three in the length direction).
