[Basic configuration]
Hereinafter, based on the Example shown in FIG. 1 thru | or FIG. 9, the structure of the sheet | seat 1 which concerns on this invention, its effect | action, and an effect are demonstrated.
First, the basic configuration of the seat 1 according to the present invention 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 during use and absorbing 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 that is processed into a round shape and a tapered portion 19 that has a width that narrows downward at a 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 that is 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 of the seat 1 according to the present invention, its operation, and effects will be described by taking the illustrated embodiment as an example.

  This sheet 1 has (1) a three-dimensional structure excellent in capturing and following of the residual urine U, (2) a folding guide structure applied to the seat body 9 in order to improve the wearing feeling, and the pants P.

Moreover, the formation aspect of the said notch part 49 and the flap piece 51 is not restricted to the formation aspect shown to FIG. 1 thru | or FIG.3 and FIG.6. For example, as shown in FIG. 7A, the notch 49 may be formed by a simple slit 57, or may be formed by an inverted U-shaped narrow groove 59 having a small maximum width D as shown in FIG. 7B. Is possible.

Further, as shown in FIG. 7C, the sheet main body 9 is turned upside down to form a notch 49 in the center of the grip portion 31, and the upper portion of the sheet main body 9 including the grip portion 31 described later (FIG. c) can be used as the flap piece 51.
Further, as shown in FIG. 7 (d), the lower surface of the back sheet 7 of the sheet main body 9 (the flap piece 51) is in a range where the free movement toward the three-dimensional structure of the flap piece 51 is not restricted. It is possible to form the adhesive portion 13C only at the outer edges on the left and right sides in the figure. In this case, it is preferable that the adhesive strength of the adhesive portion 13 </ b> C is weaker than the adhesive strength of the other adhesive portions 13 formed on the back surface of the back sheet 7.

Further, when the three-dimensional structure configured as described above is adopted, the seat body is also provided for the trunks-type pants P3 shown in FIG. The simple container 53 is formed by superimposing the left and right flap pieces 51, 51 with a simple configuration in which a notch portion 49 is formed in a part of 9, and the residual urine in the downward direction by the space A in the simple container 53 It becomes possible to prevent leakage of U.
In addition, the simple container 53 includes the rigidity of the flap pieces 51 and 51 generated by overlapping the left and right flap pieces 51 and 51 as described above, the pants P in the pants P, and the pants worn on the outside of the pants and the like. Since the three-dimensional shape is maintained by the pressure, the residual urine U is changed while following the movement of the user's body without changing the movement of the user's body and changing the overlap amount of the flap pieces 51, 51. Will be captured.
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).

(2) Bending guide structure In FIG. 1, the first bending guide portion 21 for bending the sheet main body 9 along the horizontal axis direction X, which is the width direction of the sheet main body 9, and the length of the sheet main body 9. A second bending guide portion 23 for bending the sheet main body 9 along the longitudinal direction Y, which is the vertical direction, is provided. The bending direction by the first bending guide portion 21 is not limited to the direction exactly parallel to the horizontal axis direction X (a direction parallel to the horizontal axis direction X), and may be a direction slightly inclined from the horizontal axis direction X. . Similarly, the bending direction by the second bending guide portion 23 is not limited to the direction exactly along the vertical axis direction Y (a direction parallel to the vertical axis direction Y), and may be a direction slightly inclined from the vertical axis direction Y. Good.

  As shown in the figure, the first bending guide portion 21 may be formed as a relatively large constricted portion 25A constricted in a curved V shape at or near the center of both side portions of the sheet body 9. . Further, the second bend guide part 23 may use the aforementioned notch part 49 (for example, the inverted V-shaped notch 55) as the constricted part 25B of the second bend guide part 23.

  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, the longitudinal direction Y connecting the constricted portion 25B (notch 55) 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 is provided. The sheet body 9 bends with the two straight lines L2 and L2 generally extending along the lines as folding lines.

A groove 35 having a predetermined length extending along the straight lines L1 and L2 shown in FIG.
Further, as shown in FIG. 8 (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.
Further, as shown in FIG. 8A, the second bending guide portion 23 may be provided on the upper edge 29 side of the sheet body 9, for example, at both end portions 31a of the grip portion 31 described later. Moreover, when providing the 2nd bending guide part 23 in the upper edge 29 side of the sheet | seat main body 9, a recessed part of semicircle shape etc. may be sufficient.

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.

(3) Adhering Guide Structure In FIG. 1, a grip portion 31 having an arc shape is formed so as to protrude upward at the center of the upper edge 29 of the sheet body 9 as an example. 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.

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 position and inclination of the sheet main body 9. By providing the tapered portion 19, the left and right openings of the pants P can be corrected. 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 the portions 45, 45 or from the lower corner portion of the sheet main body 9.

(4) 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 three stages 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. For example, as shown in FIG. 2, the bonding portions 13 formed on the back surface of the back sheet 7 are regularly formed in two rows on the left and right and three steps on the top and bottom. The non-adhesive portions 15 having no adhesive force or weakened adhesive force may be formed so as to be regularly arranged.

  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). In the illustrated embodiment, the dimensions of the adhesive portion 13 </ b> A disposed in the upper two steps of the sheet body 9 and the adhesive portion 13 </ b> B disposed in the lower portion of the sheet body 9 are changed according to the shape of the sheet body 9. 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.

Specifically, the width of the bonding portion 13A arranged in the upper two steps is set to about 39 mm in width and the height is set to about 23 mm, and the size of the bonding portion 13B arranged in the lower one step is set to the width. Is set to about 25 mm and the height is set to about 23 mm.
Further, the adhesive portion 13A arranged in the upper two steps is the same as the adhesive portion 13B, an adhesive portion having a width of about 25 mm and a height of about 23 mm, and an adhesive portion having a width of about 14 mm and a height of about 23 mm. Are arranged so that a gap S of about 1 mm is formed in the middle.

A non-adhesive portion 15A in the vertical axis direction having a width of about 13 mm is formed between the two right and left adhesive portions 13, and a horizontal axis direction in which the height is about 6 mm between the upper and lower three-tier adhesive portions 13. The non-bonding portion 15B is formed. As described above, the non-adhesive portion 15 is provided on the back surface of the back sheet 7 on which the grip portion 31 is provided, the outer side space of the lower one-step adhesive portion 13B, and the peripheral edge of the back surface of the back sheet 7.

  In addition, even if it superimposes the flap piece 51 mentioned above with respect to underpants P before wearing, since the said three-dimensional structure cannot be maintained, about the said three-dimensional process, it implements after wearing. In this case, as shown in FIG. 7 (d) described above, when the structure in which the adhesive portions 13C are formed at the left and right edges of the lower portion of the seat body 9 is used, It becomes possible to hold the formed constant space A.

[Other embodiments]
The above is a basic example of the present invention, but the sheet 1 of the present invention is not limited to the above-described example, and changes in the partial configuration within the scope not departing from the gist of the present invention. It is possible to omit or add conventional techniques known to those skilled in the art.
For example, the characteristic configurations shown in the above (1) to (4) can be applied individually, or a part of them can be applied in combination, or all of them can be applied in combination. Is possible.

Further, in addition to the above-described characteristic configuration, the following color of the top sheet 3 is used in order to make it difficult to notice that the sheet 1 is affixed by a nearby person when adding small items on the go. It is also possible to adopt a structure.
As the color of the top sheet 3, a black or gray achromatic color or a chromatic color having an equivalent lightness (for example, close to an achromatic color) can be employed as an example. Specifically, black or gray color, preferably gray color from 1st to 6th, or equivalent, except for white of 10th among 11 levels of Munsell color system from 0th to 10th A chromatic color having lightness (for example, close to an achromatic color) can be employed.

  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 has a feeling of resistance when used, but the above-mentioned gray color or gray equivalent color reduces the resistance and makes it easy to use. 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.

Further, the shape of the grip portion 31 employed in the pasting guide structure of (3) is not limited to the arc shape, and various shapes such as a rectangular shape, a trapezoidal shape, and a triangular shape are applicable. Further, in order to provide a function of the grip 31 in the vicinity of the lower edge 27 of the sheet body 9 when the sheet 1 is used upside down, the vicinity of the lower edge 27 is used as the non-adhesive portion 15. The grip portion 31 can be changed to a shape that can be easily gripped by hand.
In addition, the cut portion 49 employed in the three-dimensional structure of (1) is provided on both the upper edge 29 side and the lower edge 27 side of the sheet main body 9, and depending on the direction in which the sheet main body 9 is attached, It is also possible to select and use 49. In addition, if the cut body 49 is provided on both the upper edge 29 side and the lower edge 27 side of the sheet body 9 and the required strength of the sheet body 9 cannot be maintained, the cut section 49 is weakened such as perforations. It is also possible to use as the cut portion 49 a portion that is formed by a structure and cut off any portion to which the weakened structure is applied during use.
In addition, it cannot be overemphasized that the technical idea of this invention is applicable to the sheet | seat for women.
