Description

[Technical field]

[0001] The present disclosure relates to holder pants. [Background technology]

[0002] Conventionally, holder pants are used to hold absorbent pads such as urine pads and sanitary napkins between the legs of a wearer. After the absorbent pad has absorbed bodily fluids, the wearer only needs to replace the absorbent pad with a new one, and the holder pants themselves can be washed as needed and reused, which provides cost benefits and reduces the burden on the environment.

[0003] For example, Patent Document 1 discloses sanitary shorts as holder pants for sanitary napkins, which are composed of a front body, a back body, and a crotch cloth portion located between the two, and both the front body and the back body have a front body waist belt portion and a back body waist belt portion at the upper part of the waist. Support shorts are sewn and fixedly attached to the back body waist belt portion of these sanitary shorts. The support shorts are composed of a back body sewn portion, a front body fixed portion, and a straddling portion located between the two. In the thin belt area of ​​the straddling portion of the support shorts, a thin belt opening is provided from the part that contacts the perineum to the part that contacts the urethral opening, which stably holds the napkin and prevents menstrual blood leakage. In addition, the front body fixed portion of the support shorts is composed of two joining bands to adjust the pressure feeling of the napkin. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2022-000201 Summary of the Invention [Problem to be solved by the invention]

[0005] When conventional holder pants were worn with pants pads or urine pads (hereinafter simply referred to as "urine pads"), they applied too much pressure and fitted too tightly to the body, leaving no extra space in the crotch area to receive urine, making it easy for urine to leak.

[0006] The sanitary shorts described in Patent Document 1 are designed to protect against menstrual blood and are not suitable as urine-absorbing pads, and therefore are insufficiently effective against urination.

[0007] Therefore, an object of the present disclosure is to provide holder pants capable of preventing urine leakage. [Means for solving the problem]

[0008] In order to solve the above problems, a first aspect of the present invention is holder pants used to hold an absorbent pad, comprising a front body that is located on the wearer's stomach side when worn, a back body that is located on the back side, and a crotch portion that is located under the crotch and connects the front body and the rear body, and has an opening that is located in the widthwise center of the crotch portion and in the front-to-back center and extends in the front-to-back direction, the opening being trapezoidal in shape with a wider width at the front and narrower width at the rear, and the length of the opening in the front-to-back direction is 125 mm or more.

[0009] A second aspect of the present invention is the holder pants according to the first aspect, further comprising a stretchable covering fabric that covers the opening.

[0010] A third aspect of the present invention is the holder pants according to the second aspect, wherein the covering fabric is a stocking fabric. Effect of the Invention

[0011] According to the present disclosure, holder pants capable of preventing urine leakage can be provided. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, holder pants according to one embodiment of the present invention will be described with reference to the drawings.

[0014] In this specification, wearing the holder pants means a state in which the holder pants are worn on the body, regardless of whether the absorbent pad absorbs bodily fluids before, during, or after the absorption. In addition, the "front side" means the direction that is the wearer's ventral side when the holder pants are worn, and the "rear side" means the direction that is the wearer's dorsal side. In addition, the "upper side" means the direction that is the wearer's head side when the holder pants are worn, and the "lower side" means the direction that is the wearer's foot side. In addition, the left-right direction means the left-right direction as seen from a wearer facing forward. In addition, the width direction means a direction perpendicular to the front-rear direction (a direction along the left and right). In addition, the skin side of each component of the holder pants means the direction toward the wearer's skin side when the holder pants are worn, and the non-skin side means the direction opposite to the skin side. In addition, the body fluid means liquid discharged from the body to the outside, such as urine, blood, and water in loose stool.

[0015] Fig. 1 is an external view of holder pants according to one embodiment of the present invention when worn. Fig. 2 is an external view showing the holder pants as viewed from the front. Fig. 3 is a plan view of the crotch part of the holder pants as viewed from the waist opening side. Fig. 4 is an external view showing a modified example of the holder pants as viewed from the front. Note that each drawing does not stipulate the size relationship of the components of the holder pants, and the dimensions of each component can be appropriately selected from a wide range depending on the purpose of the holder pants, the age of the intended wearer, etc.

[0016] (Holder Pants) As shown in Fig. 1, the holder pants 10 according to this embodiment are worn with an absorbent pad 100, such as a light incontinence pad, positioned in the crotch area of ​​the wearer. That is, the holder pants 10 are used to hold the absorbent pad 100 in the crotch area of ​​the wearer. After the absorbent pad 100 absorbs bodily fluids, the wearer can replace only the used absorbent pad 100 with a new absorbent pad 100, and reuse the holder pants 10. In this way, the holder pants 10 can be reused by washing them as necessary, which is cost-effective and reduces the burden on the environment.

[0017] The absorbent pad 100 to be held by the holder pants 10 may be a urine absorption pad, a light incontinence pad, a light incontinence liner, a sanitary napkin, etc. The dimensions are specified below, but are values ​​measured in an unstretched state.

[0018] As shown in Figs. 1 to 3, the holder pants 10 include a front body 11 located on the wearer's abdomen when worn, a back body 12 located on the back side, and a crotch section 13 located under the crotch and connecting the front body 11 and the back body 12. In addition to the front body 11, the back body 12, and the crotch section 13, the holder pants 10 of this embodiment also include a covering fabric 14 that covers the crotch section 13 from the non-skin side. Note that, in addition to the front body 11, the back body 12, and the crotch section 13, the holder pants 10 may also include leg sections that extend continuously downward from these and cover the wearer's thighs.

[0019] The front body 11, the back body 12, and the crotch part 13 of the holder pants 10 are underwear made by knitting yarn material, and have elasticity in the vertical, horizontal, and front-to-back directions. The yarn material constituting the holder pants 10 includes synthetic fiber yarns such as polyester, polyamide, polypropylene, and polyacrylonitrile, regenerated fiber yarns such as rayon, cupra, and acetate, and spun yarns, processed yarns, and mixed yarns obtained from these. The above-mentioned yarn material further includes natural fibers such as cotton, wool, hemp, and silk, and mixed yarns thereof, but is not limited to these.

[0020] The upper edges of the front body 11 and the back body 12 define a waist opening 15 through which the wearer's waist is inserted when worn. The lower edges of the front body 11, the lower edges of the back body 12, and the left and right edges of the crotch section 13 define left and right leg openings 16 through which the wearer's legs are inserted when worn. The waist opening 15 and the waist opening 15 are each stretchable in the circumferential direction. The upper edges of the front body 11 and the back body 12 that define the waist opening 15 may be made of an elastic stretchable member that extends in the circumferential direction and has stretchability. Examples of the elastic stretchable member include stretchable woven or nonwoven fabrics containing polyurethane fibers, synthetic rubber sheets, and natural rubber sheets.

[0021] (Front) The front body 11 is formed of a thin elastic fabric. The upper edge of the front body 11 defines the front side of the waist opening 15. Of the lower edge of the front body 11, the central part in the width direction is connected to the front edge 13a of the crotch part 13, and both side parts in the width direction define the front sides of the left and right leg openings 16. The front body 11 may be formed of a single piece of fabric, or may be formed by connecting or arranging multiple pieces of fabric in layers.

[0022] (Back) The back body 12 is formed of a thin elastic fabric. The upper edge of the back body 12 defines the rear side of the waist opening 15. Of the lower edge of the back body 12, the central part in the width direction is connected to the rear edge 13b of the crotch part 13, and the two side parts in the width direction define the rear sides of the left and right leg openings 16. The back body 12 may be formed of a single piece of fabric, or may be formed by connecting or arranging multiple pieces of fabric in layers. The back body 12 and the front body 11 may be formed of a single piece of fabric that is continuous with each other.

[0023] (Crotch area) As shown in Fig. 3, the front edge 13a of the crotch portion 13 is curved in a generally arc shape with the widthwise center bulging forward. The rear edge 13b of the crotch portion 13 is curved in a generally arc shape with the widthwise center bulging backward. The left and right edge portions of the crotch portion 13 are curved so that the intermediate portions in the front-rear direction are concave inward in the width direction. The length L1 in the front-rear direction of the crotch portion 13 is at least 125 mm.

[0024] (opening) The crotch portion 13 has an opening 17 extending in the front-rear direction. The shape of the opening 17 is a symmetric trapezoid with a wide width W1 on the front side and a narrow width W2 on the rear side (W1>W2). The opening 17 is disposed in the center of the crotch portion 13 in the width direction. Disposing the opening 17 in the center of the crotch portion 13 in the width direction means disposing the center position of the opening 17 in the width direction at the center position of the crotch portion 13 in the width direction. Also, the opening 17 is disposed in the center of the crotch portion 13 in the front-rear direction. Disposing the opening 17 in the center of the crotch portion 13 in the front-rear direction means disposing the center position of the opening 17 in the front-rear direction at the center position of the crotch portion 13 in the front-rear direction. In other words, the length L2 in the front-rear direction from the front end of the crotch portion 13 to the front end of the opening 17 and the length L3 in the front-rear direction from the rear end of the crotch portion 13 to the rear end of the opening 17 are the same length (L2=L3). Thus, the holder pants 10 have an opening 17 that is disposed at the center in the width direction and the center in the front-rear direction of the crotch portion 13 and extends in the front-rear direction.

[0025] The length L4 in the front-rear direction of the opening 17 is 125 mm or more. If the length L4 in the front-rear direction of the opening 17 is made shorter than 125 mm, it becomes difficult to release the pressure of the absorbent pad 100 that has absorbed and swelled with bodily fluids through the opening 17, and the amount of water that can be absorbed before urine leakage from the absorbent pad 100 occurs decreases. The upper limit of the length L4 in the front-rear direction of the opening 17 is equal to or less than the length L1 in the front-rear direction of the crotch portion 13.

[0026] At the front end portion of opening 17, the widthwise distance from the left and right leg openings 16 (the left and right edges of the crotch portion 13) to opening 17 is preferably 15 mm or more, and more preferably 20 mm or more. The front width W1 of opening 17 is preferably 18 mm or more and 35 mm or less. Also, the rear width W2 of opening 17 is preferably 6 mm or more and less than the front width W1. By setting the front width W1 and rear width W2 of opening 17 within the above ranges, the amount of water absorbed before urine leakage from the absorbent pad 100 occurs can be improved.

[0027] (Covering fabric) The covering fabric 14 is a stretchable fabric that covers the opening 17 and has higher stretchability than the fabric of the crotch portion 13. The covering fabric 14 is breathable. The covering fabric 14 of this embodiment covers the entire area of ​​the opening 17. The covering fabric 14 is provided on the holder pants 10 in a state of surface contact with the non-skin side of the crotch portion 13, for example. Examples of the covering fabric 14 include mesh fabric, tights fabric, stocking fabric, etc., but stocking fabric is preferable from the viewpoint of thinness. The stocking fabric is a stretchable knitted fabric knitted by a known knitting method using knitting yarn containing synthetic fibers. The covering fabric 14 is preferably a decorative fabric that has a design such as color and pattern.

[0028] In this embodiment, the cover fabric 14 that covers the opening 17 is provided on the holder pants 10, but this is not limited to this, and as shown in FIG. 4, the cover fabric 14 does not have to be provided on the holder pants 10.

[0029] In the holder pants 10 configured as described above, the opening 17 is provided in the crotch portion 13, so that the pressure of the absorbent pad 100 that has absorbed bodily fluids and swelled can be released through the opening 17. This makes it possible to secure a space between the wearer's body and the absorbent pad 100, thereby preventing urine leakage.

[0030] Moreover, the opening 17 is disposed at the center of the width direction of the crotch portion 13 and at the center of the front-rear direction. If the opening 17 is disposed closer to the front side than the center of the front-rear direction of the crotch portion 13, there will be no opening on the rear side of the crotch portion 13, so the pressure of the absorbent pad 100 that has absorbed and swelled with bodily fluids cannot be released at the rear side, and the amount of water absorption will decrease. On the other hand, if the opening 17 is disposed closer to the rear side than the center of the front-rear direction of the crotch portion 13, there will be no opening on the front side of the crotch portion 13, so it is difficult to secure a space between the front side of the crotch where the urethral opening is located and the absorbent pad 100, so the amount of water absorption will decrease and urine leakage will easily occur. In the holder pants 10 of this embodiment, the opening 17 is disposed at the center of the width direction of the crotch portion 13 and at the center of the front-rear direction, so the amount of absorption can be secured and urine leakage can be suppressed.

[0031] In addition, since the length L4 of the opening 17 in the front-rear direction is 125 mm or more, the pressure of the absorbent pad 100 that has absorbed bodily fluids and swelled can be released through the opening 17. This makes it possible to secure a space between the wearer's body and the absorbent pad 100, thereby preventing urine leakage.

[0032] Also, the opening 17 is formed in a trapezoid shape with a wide front width and a narrow rear width. In this way, since the opening 17 is wide on the front side close to the urethral opening, the pressure of the absorbent pad 100 that has absorbed bodily fluids and swelled can be released at the front side close to the urethral opening, and a space can be secured between the wearer's body and the absorbent pad 100. Also, since the opening 17 is narrow on the rear side, the tightening force against the body can be increased toward the rear side, and the absorbent pad 100 can be adequately supported. This can prevent urine leakage.

[0033] In this way, according to this embodiment, it is possible to provide holder pants 10 capable of preventing urine leakage.

[0034] In addition, since the cover fabric 14 having elasticity that covers the opening 17 is provided, the opening 17 can be made less visible, improving the appearance. In addition, since the cover fabric 14 has elasticity, the appearance of the opening 17 can be improved without impeding its function.

[0035] Furthermore, by using stocking material for the covering material 14, the function of the opening 17 is not impaired and the appearance can be improved.

[0036] The results of experiments carried out by the inventors will be described below.

[0037] FIG. 5 is a graph showing the relationship between the length of the opening of the holder pants and the amount of water poured in before it leaks from the absorbent pad. FIG. 6 is a graph showing the relationship between the shape of the opening of the holder pants and the amount of water poured in before it leaks from the absorbent pad. FIG. 7 is a graph showing the relationship between the position of the opening of the holder pants and the amount of water poured in before it leaks from the absorbent pad. The horizontal axis of FIG. 5 shows the length of the opening of the holder pants. The horizontal axis of FIG. 6 shows the shape of the opening of the holder pants. The horizontal axis of FIG. 7 shows the front and rear positions of the opening of the holder pants. The vertical axes of FIG. 5 to FIG. 7 show the amount of water poured in until the physiological saline used in the experiment described later leaks from the absorbent pad.

[0038] (Experimental Method) First, the weight of a new absorbent pad before use is measured. Next, the holder pants are put on the dummy in a state where the absorbent pad is placed in the crotch area of ​​the dummy in a standing position. Next, blue-colored saline is injected into the absorbent pad from a virtual urethral opening provided in the crotch area of ​​the dummy at a constant speed (4.6 ml / sec to 5.3 ml / sec). Then, when it is visually confirmed that the saline has leaked from the absorbent pad, the injection of the saline is stopped. After the injection of the saline is stopped, the absorbent pad is removed from the dummy and the holder pants, and the weight of the absorbent pad after the water injection is measured. The difference between the weight of the absorbent pad after the water injection and the weight of the new absorbent pad before use is taken as the amount of water injected until leakage from the absorbent pad (hereinafter, sometimes referred to as "absorption amount"). Note that the method of measuring the amount of water injected until leakage from the absorbent pad is not limited to the above, and may be obtained by, for example, calculating (water injection speed) x (time until leakage). The virtual urethral opening of the dummy doll is located forward of the position directly under the crotch of the dummy doll, and faces approximately the center between the front end of the crotch part and the center of the crotch part in the front-to-rear direction when the holder pants are worn.

[0039] (Opening length and water amount) As shown in FIG. 5, in an experiment on the relationship between the length of the opening of the holder pants and the amount of water injected before leaking from the absorbent pad, four holder pants were prepared, each differing only in the length of the opening in the crotch part in the front-rear direction. The shape of the opening of the four holder pants was a rectangle with a width of 12 mm that was long in the front-rear direction. The position of the opening of the four holder pants was the center of the width direction of the crotch part and the center of the front-rear direction. The length of the opening in the front-rear direction of the holder pants A was 105 mm. The length of the opening in the front-rear direction of the holder pants B was 125 mm. The length of the opening in the front-rear direction of the holder pants C was 145 mm. The length of the opening in the front-rear direction of the holder pants D was 165 mm. The above water injection experiment was performed using these four holder pants. As shown in Figure 5, when the length of the opening in the front-to-back direction was A, 105 mm, the absorption volume was 460 ml, when it was B, 125 mm, the absorption volume was 485 ml, when it was C, 145 mm, the absorption volume was 476 ml, and when it was D, 165 mm, the absorption volume was 499 ml. Thus, it was confirmed that the absorption volume (amount of water injected) increases when the length of the opening of the holder pants in the front-to-back direction is 125 mm or more.

[0040] (Opening shape and water amount) As shown in FIG. 6, in an experiment on the relationship between the shape of the opening of the holder pants and the amount of water poured in before leaking from the absorbent pad, five holder pants (A to E) were prepared, each differing only in the shape of the opening in the crotch area. The opening of the holder pants A was rectangular, with a width of 12 mm and a length of 125 mm in the front-to-back direction. The opening of the holder pants B was lantern-shaped, with the center part in the front-to-back direction being wider in the width direction, and the maximum length in the width direction was 12 mm and the maximum length in the front-to-back direction was 125 mm. The opening of the holder pants C was trapezoidal, with a front side width of 6 mm, a rear side width of 18 mm, and a front-to-back length of 125 mm, with the rear side being wider. The opening of the holder pants D was trapezoidal, with a front side width of 18 mm, a rear side width of 6 mm, and a front-to-back length of 125 mm, with the front side being wider. The opening of the holder pants E was a linear cut with a length of 125 mm in the front-to-back direction. The positions of the openings of the five holder pants were the center of the width direction of the crotch area and the center of the front-to-back direction. The water injection experiment was carried out using these five holder pants. As shown in Figure 6, when the opening shape was rectangular (A), the absorption amount was 485 ml, when it was lantern-shaped (B), the absorption amount was 480 ml, when it was trapezoidal (C) with a wider back side, the absorption amount was 472 ml, when it was trapezoidal (D) with a wider front side, the absorption amount was 510 ml, and when it was a straight cut (E), the absorption amount was 459 ml. Thus, it was confirmed that the absorption amount (water injection amount) was increased when the opening shape of the holder pants was trapezoidal with a wider front side.

[0041] (Opening position and water injection amount) As shown in FIG. 7, in an experiment on the relationship between the position (front-rear position) of the opening of the holder pants and the amount of water poured in before leaking from the absorbent pad, three holder pants were prepared, each differing only in the front-rear position of the opening in the crotch part. The shape of the opening of the three holder pants was a trapezoid with a front side width of 18 mm, a rear side width of 6 mm, and a front-rear length of 125 mm, which was wider at the front. The position in the width direction of the opening of the three holder pants was the center in the width direction of the crotch part. The opening of the holder pants A is arranged so that the center of the opening in the front-rear direction coincides with the center of the crotch part in the front-rear direction. The opening of the holder pants B is arranged so that the center of the opening in the front-rear direction coincides with the virtual urethral opening of the dummy doll. Since the virtual urethral opening of the dummy doll is located forward of the center of the crotch part in the front-rear direction, the opening of the holder pants B is located forward of the opening of the holder pants A. The opening of the holder pants C is arranged so that the front end of the opening is located 10 mm forward from the virtual urethral opening of the dummy doll. The opening of holder pants C is located behind the opening of holder pants A. The above water injection experiment was carried out using these three holder pants. As shown in Figure 7, when the front-to-back position of the opening was in the center of A (the center of the crotch in the front-to-back direction), the absorption amount was 510 ml, when it was in front of B (more forward than A), the absorption amount was 420 ml, and when it was behind C (more forward than A), the absorption amount was 460 ml. Thus, it was confirmed that the absorption amount (amount of water injected) was higher when the front-to-back position of the opening of the holder pants was located in the center of the crotch in the front-to-back direction.

[0042] Although the present invention has been described based on the above embodiment, the present invention is not limited to the contents of the above embodiment, and can be modified as appropriate without departing from the scope of the present invention. In other words, all other embodiments, examples, and operational techniques made by those skilled in the art based on this embodiment are naturally included in the scope of the present invention.
