  However, in the men's underwear described in Patent Document 1, it is necessary to provide a storage section at the front in order to insert the water absorbing pad, and it is necessary to use a dedicated item. Moreover, when a water absorbing pad is used for pants, there existed a problem that a water absorbing pad shifted with respect to pants.

  The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a water-absorbent pad which can cope with urine leakage and which can be easily attached and fixed while wearing the pants.

A water absorbing pad according to an aspect of the present invention is a water absorbing pad used by being attached to a pants, wherein a surface contacting the inner surface of the pants, a back surface opposite to the front surface, and water from the back surface side A pad portion to absorb, a bag portion into which a human hand can be inserted, and an adhesive applied or applied along the vertical direction in the state where the water absorbent pad is attached to the pants on the surface; A cover member for covering the adhesive, the bag portion being provided on at least one of either the lower end side of the front surface or the lower end side of the back surface, the cover member extending in the vertical direction along the adhesive extending the formed longer than the pressure-sensitive adhesive to have a portion that is not in contact with the adhesive part comprising at least one longitudinal end, Ri peelable der from the pressure-sensitive adhesive, said bag portion, Installed at the lower end of the surface The cover member is inserted into the inside of the bag portion, is folded back at the inside of the bag portion at the folded back portion, and a portion which does not contact the adhesive between the folded back portion and the longitudinal end portion There further portion between said folded portion said longitudinal ends is characterized that you have exposed from the bag portion.

According to this, since the water-absorbent pad is provided with a bag portion into which the hand of a person can be inserted in at least one of either the lower end side of the surface or the lower end side of the back surface It is easy to put in and insert in pants. In addition, since the adhesive is stuck or applied along the vertical direction, it does not shift even if the absorbent pad is attached to the pants. In addition, the cover member extends in the vertical direction along the adhesive and is formed longer than the adhesive, and has a portion not in contact with the adhesive at a part including at least one longitudinal end, and is peeled from the adhesive It is possible. Therefore, it is possible to peel off the adhesive by pinching a part of the cover member while wearing the pants. In addition, since the cover member is inserted into the inside of the bag portion and folded back inside the bag portion, the cover member does not easily come off from the adhesive when the water absorbent pad is inserted into the pants. In addition, since the cover member can be pinched even when the hand is put in a bag provided on the lower end side of the surface or the hand is pulled out of the bag, the cover member can be peeled off more easily.

  Further, the folded portion of the water absorbent pad may be in contact with the bottom of the bag portion. In this case, since the user does not have to be aware that the lower end of the cover member peels off when inserting the hand into the bag portion, the absorbent pad can be firmly pushed into the pants.

  Moreover, the said bag part of a water absorbing pad may be provided in the lower end side of the said back surface. In this case, since the absorbent pad can insert the hand into the bag without touching the cover member, the hand does not accidentally peel off the cover member when mounted on the pants.

  In addition, the cover member of the water absorbent pad may have a length twice or more the length of the adhesive applied or applied. In this case, even if a portion of the cover member not in contact with the adhesive moves in the pants, a part of the cover member can be easily grasped, so the cover member can be peeled off more easily.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The drawings referred to are used to explain the technical features that can be adopted by the present invention. The configurations described in the drawings are not intended to limit the present invention, but merely illustrative examples.

<Schematic Configuration of Water Absorbent Pad 1>
The schematic configuration of the water absorbent pad 1 according to the embodiment of the present invention will be described with reference to FIGS. 1 to 8. The water absorbent pad 1 is used by being attached to the pants 25 (see FIG. 8). In the following description, as shown in FIG. 1 and FIG. 6, in the water absorbent pad 1, the upper and lower directions in the state of being attached to the pants 25 are referred to as the vertical direction. It is defined as right and left. Further, as shown in FIGS. 2 to 5 and 7, the left side and the right side are defined as the front and the back, respectively, the side in contact with the pants 25 is the front 11, and the opposite side is the rear 12.

  The water-absorbent pad 1 has a surface 11 in contact with the inner surface of the pants 25, a back surface 12 opposite to the surface 11, a pad portion 2 for absorbing water from the back surface 12, and a bag into which a human tip 20 can be inserted. The unit 3 is provided. Further, on the surface 11 of the water absorbing pad 1, the adhesive 4 attached or applied along the vertical direction in the state where the water absorbing pad 1 is attached to the pants 25, and the cover member 5 covering the adhesive 4 Equipped with The bag portion 3 is provided on at least one of the lower end side of the front surface 11 and the lower end side of the back surface 12. The cover member 5 extends in the vertical direction along the adhesive 4 and is formed longer than the adhesive 4 and has a portion 5a which does not contact the adhesive 4 at a part including at least one longitudinal end 8 or 9 Can be removed from the adhesive 4.

  <Detailed Configuration of Water Absorbent Pad 1> Next, the water absorbent pad 1 according to the embodiment of the present invention will be described in detail. The embodiment includes the first to fourth embodiments as will be described later. First, the common parts will be described. As shown in FIGS. 1 and 6, the adhesive 4 is attached or applied in the vertical direction along the center line in the left-right direction (A-A cutting line, B-B cutting line correspond) to the surface 11 of the pad portion 2 It is done. The adhesive 4 may be attached with an adhesive tape, or the adhesive 4 may be directly applied to the surface 11 of the pad portion 2. The cover member 5 has a width in the left-right direction equal to or greater than the width of the adhesive 4 at least in a portion covering the adhesive 4. Further, the cover member 5 does not necessarily extend in parallel to the adhesive 4, and may extend in the vertical direction including the portion 5 a not in contact with the adhesive 4.

  As shown in FIGS. 2 to 5 and 7, the pad portion 2 is a pad that absorbs water such as urine, and has a three-layer structure. The pad portion 2 is formed by covering the water-absorbent core material 10 having water absorbability with the liquid-impervious sheet 11 a which is the surface 11 and the liquid-permeable sheet 12 a which is the back surface 12. The liquid-impervious sheet 11 a prevents the moisture absorbed by the water-absorbent core material 10 from leaking out to the outside of the surface 11. The liquid-permeable sheet 12 a allows moisture such as urine to permeate from the back surface 12 and causes the water-absorbent core material 10 to absorb water. As shown in FIGS. 1 and 6, both side edge flaps 13, an upper flap 14 and a lower flap 15 are formed on the outer side of the periphery of the water absorbent core 10, and the water absorbent core 10 is impervious to liquid And the liquid-permeable sheet 12a. The sack portion 3 has an insertion opening 3a into which the tip 20 of a person is inserted at the lower end side of the front surface 11 or the lower end side of the back surface 12, and is joined to the side edge flap 13 and the lower flap 15.

  The pad portion 2 has a constant thickness in the front and back direction. The thickness of the water-absorbent core material 10 which is a part of the pad portion 2 in the front and back direction is, for example, 3 mm, 5 mm, 10 mm or the like. The thickness in the front and back direction may be selected according to the material and the amount of water absorption of the material of the water-absorbent core 10. In addition, the pad part 2 does not necessarily need to be fixed thickness, and thickness may differ partially.

  As shown in FIGS. 1 and 6, the pad portion 2 has a shape in which the width in the left-right direction narrows downward. The lower end portion of the pad portion 2 may be semicircular as shown in FIG. 1, or the lower end portion may be straight in the horizontal direction and the whole may be in the shape of inverted trapezoidal. As a result, the water absorbent pad 1 can be fitted and fitted to the inner shape of the pants 25 (see FIG. 8). Furthermore, the pad portion 2 may be in the shape of an inverted triangle. In addition, the pad portion 2 may be made of a water-soluble material so that it can be flushed to the flush toilet. In addition, although the pad part 2 demonstrated three-layer structure, it does not restrict to this. For example, the pad portion 2 may have a two-layer structure including the water-absorbent core 10, a single-layer structure of only the water-absorbent core 10, or a structure of four or more layers. When the pad portion 2 has a single-layer structure of only the water absorbent core 10, the front surface of the water absorbent core 10 is the front surface 11, and the rear surface is the rear surface 12.

  <Method of Wearing Water Absorbent Pad 1> Next, a method of wearing the water absorbent pad 1 with the pants 25 worn will be described with reference to FIG. The absorbent pad 1 is inserted between the penis 21 and the scrotum 22 and the front of the pants 25 with the pants 25 worn. The front surface 11 is a side in contact with the inner surface of the pants 25, and the back surface 12 is a side in contact with the penis 21, and is inserted into the pants 25 with the hand 20 inserted in the bag portion 3. When the water absorbent pad 1 reaches the mounting position, the portion 5a of the cover member 5 not in contact with the adhesive 4 is pinched, and the cover member 5 is pulled upward while being peeled from the adhesive 4. When the cover member 5 is peeled off, the adhesive 4 is exposed on the surface 11, so the adhesive 4 is attached to the inside of the front of the pants 25. As shown in FIG. 8, the water absorbent pad 1 can be attached to the inside of the pants 25.

<Common effect of absorbent pad 1>
As described above, the water absorbent pad 1 exhibits various effects. As shown in FIG. 1 to FIG. 7, the water absorbent pad 1 is provided with a bag portion 3 into which a human hand 20 can be inserted in at least one of the lower end side of the surface 11 and the lower end side of the back surface 12. Therefore, the absorbent pad 1 can be easily inserted into the pants 25 by putting the hand 20 in the bag portion 3 with the pants 25 worn. In addition, since the adhesive 4 is attached or applied along the vertical direction, even when the absorbent pad 1 is attached to the pants 25, there is no deviation. In addition, the cover member 5 extends in the vertical direction along the adhesive 4 and is formed longer than the adhesive 4, and a portion 5 a which does not contact the adhesive 4 at a part including at least one longitudinal end 8, 9 And is peelable from the pressure-sensitive adhesive 4. Therefore, in the state where the pants 25 are worn, part of the cover member 5 can be pinched and peeled off from the adhesive 4.

  When the user wears the pants 25 to which the water absorbent pad 1 is attached, urine or the like is absorbed by the water absorbent core 10 through the liquid permeable sheet 12 a which is the back surface 12 in contact with the penis 21. Since the surface 11 is the liquid-impervious sheet 11 a, the urine absorbed by the water-absorbent core material 10 does not penetrate the inside of the pants 25. Further, the pad portion 2 is formed so as to conform to the shape of the pants 25 because the width in the left-right direction narrows downward as the pad portion 2 narrows, and the user feels uncomfortable when the water absorbent pad 1 is used by wearing the pants 25. There is not. Furthermore, the water absorbent pad 1 can be removed from the pants 25 after use and discarded.

<Configuration and Effect of First Embodiment>
Next, the configuration of the water absorbent pad 1a according to the first embodiment of the present invention will be described. The water absorbing pad 1a is different from the water absorbing pad 1b of the second embodiment to be described later and the water absorbing pad 1c of the third embodiment in the configuration of the cover member 5, and is different from the water absorbing pad 1d of the fourth embodiment. The configuration of the unit 3 is different, and the other configurations are common. In the second, third, and fourth embodiments, elements having the same configuration or function as the first embodiment may be denoted by the same reference numerals, and the description may be omitted.

  The structure of the water absorbing pad 1a will be described with reference to FIGS. 1 and 2. In the water absorbent pad 1a, the bag portion 3 is provided on the lower end side of the surface 11, the cover member 5 is inserted into the inside 6 of the bag portion 3, and the inside 6 of the bag portion 3 is folded back at the folding portion 7. Of the cover member 5, a portion 5 a which does not contact the adhesive 4 is between the folded portion 7 and the longitudinal end portion 8. Furthermore, a part between the folded back portion 7 and the longitudinal end 8 is exposed from the bag portion 3. Therefore, since the cover member 5 is inserted into the inside 6 of the bag portion 3 and is folded back in the inside 6 of the bag portion 3, the cover member 5 is the adhesive 4 when the water absorbent pad 1 a is inserted into the pants. It is hard to peel off from. In addition, since the cover member 5 can be pinched even when the hand 20 is put in the bag portion 3 or the hand 20 is pulled out of the bag portion 3, the cover member 5 can be peeled off more easily.

  Further, as shown in FIG. 2 and FIG. 3, the folded back portion 7 of the water absorbent pad 1 is in contact with the bottom portion 3 b of the bag portion 3. Therefore, the user does not have to be aware that the lower end portion of the cover member 5 peels off when inserting the hand 20 into the bag portion 3, so the absorbent pad 1 can be firmly pushed into the pants 25. . Here, the bottom portion 3 b of the bag portion 3 is in the vicinity of a portion where the inside of the bag portion 3 is in contact with the liquid-impervious sheet 11 a which is the surface 11. The cover member 5 is in contact with at least one of the liquid-impervious sheets 11 a which is the inside of the bag portion 3 or the surface 11 in the vicinity of the folded-back portion 7 in the bottom portion 3 b. The relationship between the folded-back portion 7 and the sack portion 3 described here is the same as in the water-absorbent pad 1b of the second embodiment described later, as shown in FIG.

  In addition, the cover member 5 of the water absorbent pad 1a has a length twice or more the length of the adhesive 4 applied or applied. Therefore, even if the portion 5a of the cover member 5 not in contact with the adhesive 4 moves easily in the pants 25, a part of the cover member 5 can be easily grasped, and thus the cover member 5 can be peeled off more easily.

<Configuration and Effect of Second Embodiment>
Next, the configuration of a water absorbent pad 1b according to a second embodiment of the present invention will be described with reference to FIG. The cover member 5 of the water absorbent pad 1 b has a length different from that of the water absorbent pad 1 a. The cover member 5 is less than twice the length of the adhesive 4 applied or applied, but a part of the portion 5a not in contact with the adhesive 4 is between the folded portion 7 and the longitudinal end 8 It is exposed from the bag portion 3. In FIG. 4, although the longitudinal end 8 is exposed from the sack 3, even if the longitudinal end 8 is not exposed from the sack 3, it is between the folded portion 7 and the longitudinal end 8. It is sufficient if a part is exposed.

  As described above, in the water absorbent pad 1 b, a part of the portion 5 a of the cover member 5 not in contact with the adhesive 4 is exposed from the bag portion 3 between the folded portion 7 and the longitudinal end 8. There is. Therefore, the absorbent pad 1b can pinch the cover member 5 even after the hand 20 is pulled out of the bag portion 3 at the time of mounting. The water absorbing pad 1 b has an effect that the material cost of the cover member 5 can be reduced in addition to the same effect as the water absorbing pad 1 a.

<Configuration and Effect of Third Embodiment>
Next, the configuration of a water absorbent pad 1c according to a third embodiment of the present invention will be described with reference to FIG. The water absorbing pad 1c is different from the water absorbing pads 1a and 1b in that the portion 5a of the cover member 5 not in contact with the adhesive 4 includes the opposite longitudinal end 9. According to this configuration, even after the absorbent pad 1c is attached to the pants 25 and the hand 20 is pulled out, a part of the cover member 5 is exposed from the pants 25. It can peel off.

<Configuration and Effect of Fourth Embodiment>
Next, the configuration of a water absorbent pad 1 d according to a fourth embodiment of the present invention will be described with reference to FIGS. Unlike the water absorbent pads 1 a to 1 c, the water absorbent pad 1 d is provided with the bag portion 3 on the lower end side of the back surface 12. According to this configuration, the bag portion 3 is provided on the back surface 12 so that the tip 20 of the person does not touch the adhesive 4 and the cover member 5 when the water absorbent pad 1 d is mounted inside the pants. Therefore, when the absorbent pad 1 d is attached to the pants 25, the hand 20 does not accidentally peel off the cover member 5.

  Moreover, since the water absorbing pad 1 d is not provided with the bag portion 3 on the surface 11, the adhesive 4 can be stuck or applied to the vicinity of the lower end of the pad portion 2. Therefore, the contact length with the inside of the pants 25 becomes long, and the water absorbent pad 1d can be attached more firmly. In the example shown in FIG. 6, the width in the left-right direction of the adhesive 4 and the cover member 5 is wider than that of the water absorbent pads 1a to 1c. The water-absorbent pad 1d has no sack portion 3 on the surface 11 and has less restriction in the left-right direction of the adhesive 4. Therefore, the width of the adhesive 4 in the left-right direction can be wider, and the area can be increased. Thus, the water absorbent pad 1 d can be firmly attached to the inner surface of the pants 25.

  The width in the left-right direction of the pressure sensitive adhesive 4 can be appropriately set based on the required adhesive strength and the material of the pressure sensitive adhesive 4 and the like. The length of the cover member 5 can be variously configured as in the water absorbent pads 1a to 1c. Moreover, since the sack part 3 is provided in the lower end side of the back surface 12, it is desirable to use the material which permeate | transmits water | moisture content, such as urine similarly to the liquid-permeable sheet 12a.

<Modification>
In addition, this invention is not limited to said embodiment, A various change is possible. In the above embodiment, although the example in which the water absorbent pad 1 is mainly used for men is described, it is needless to say that it can be used for women. Moreover, although the water absorption pad 1 demonstrated the shape to which the width | variety of the left-right direction becomes narrow toward the downward direction as an example, it does not restrict to this. For example, the pad portion 2 may have another shape such as an elliptical shape, a circular shape, or a rectangular shape. Furthermore, although the bag part 3 showed the example provided only in the lower end side of any one of the surface 11 or the back surface 12, it may be provided in the lower end side of both the surface 11 and the back surface 12.

  Moreover, although the cover member 5 was integrally formed in the full length of a longitudinal direction and the width | variety of the left-right direction demonstrated the same, it does not restrict to this. For example, the cover member 5 may connect the portion in contact with the adhesive 4 and the portion 5a not in contact with the adhesive 4 in the longitudinal direction separately. Alternatively, the width in the left-right direction of the portion 5 a of the cover member 5 not in contact with the adhesive 4 may be larger or smaller than the portion in contact with the adhesive 4.
