Description

[Technical field]

[0001] The present invention relates to underwear, and more particularly to underwear for men in which a urine collection device having a flexible and stretchable tubular main body and a hollow portion formed in the main body is worn on the penis. [Background technology]

[0002] Conventionally, urine collection devices have been used that are attached to the urination part of the body to collect and retain urine. For example, a male urinary device is known that includes a funnel-shaped attachment part that is attached to a man's penis, an external urination cylinder connected to the lower end of the attachment part, and a storage container connected to the lower end of the external urination cylinder, and that collects urine excreted in the attachment part into the storage container via the external urination cylinder (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2012-110638 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional urine collection devices as described above, the urination external cylinder must be fitted along the leg and the storage container must be fixed to the thigh or below the knee, which makes them bulky and gets in the way of movement, and does not provide a comfortable fit that allows for an active lifestyle.In addition, the fitting part is harder than the human body, which can cause discomfort to the wearer and urine leakage from the fitting part.

[0005] Therefore, the inventors of the present application have conducted intensive research and developed a collection tool that can suppress leakage of collected urine and has good usability (International Publication No. 2023 / 013492). This collection tool has a cylindrical main body having flexibility and stretchability, and a hollow part formed in the main body, and the hollow part has an introduction part where one end side of the main body is opened to introduce urine, and a collection part formed continuously from the introduction part to accommodate urine. The collection tool configured in this way is worn on the penis of the wearer and used. Since such a collection tool did not exist in the past, naturally, underwear intended for use by a wearer wearing this collection tool did not exist in the past.

[0006] The present invention has been made to solve such problems, and has an object to provide underwear suitable for use by a male wearer who wears a urine collection device having a flexible and stretchable tubular main body and a hollow portion formed in the main body around the penis. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the underwear according to the present invention is underwear for men in which a urine collection device having a flexible and extensible tubular main body and a hollow portion formed in the main body is worn on the penis, and comprises a waist part that can be fixed around the waist of a wearer, a front body extending downward from the waist part, the front body having a slit that extends in the vertical direction and has a length allowing the urine collection device to be inserted and removed, and a through-hole located at the lower end of the slit and through which the penis can be inserted, and a cover member that can be opened and closed between a closed state in which the urine collection device located on the outside of the front body is covered from the outside, and an open state in which the urine collection device is exposed, and which is fixed to the front body in the closed state.

[0008] According to the present invention thus constructed, the front body of the underwear is formed with a slit that extends in the vertical direction and has a length that allows the urine collection device to be inserted and removed, and a through hole that is located at the lower end of the slit and through which the penis can be inserted, so that the underwear can be easily put on and taken off while the urine collection device is worn, or the urine collection device can be put on and taken off while the penis is passed from the inside to the outside of the front body through the through hole, and the urine collection device arranged on the outside of the front body can be prevented from coming into contact with the wearer's body while the underwear is worn. In addition, the cover member of the underwear can be opened and closed between a closed state in which the urine collection device arranged on the outside of the front body is covered from the outside, and an open state in which the urine collection device is exposed, and since it is fixed to the front body in the closed state, the urine collection device can be reliably held between the cover member and the front body in the closed state. In addition, when the cover member is in the open state, the urine collected in the urine collection device can be discharged into a urinal while standing, without having to take off all of the pants and underwear, just like a normal urination action, and discharge can be easily performed. Therefore, it is possible to realize proper use of the urine collection device while reducing the burden on the wearer.

[0009] In the present invention, both widthwise ends of the cover member are preferably detachably attached to the front body.

[0010] According to the present invention configured in this manner, both widthwise ends of the cover member can be detached from the front body to open it wide, making it easier to handle the urine collection device when pulling it out through the slit in the front body while wearing the underwear or when discharging urine from the urine collection device. Also, by attaching both widthwise ends of the cover member to the front body in the closed state, it is possible to prevent the urine collection device from falling left or right or expanding in the width direction and becoming exposed to the outside from the cover member.

[0011] In the present invention, preferably, a lower end portion of the cover member is joined to the front body portion below the through hole, and the cover member can be opened and closed with the lower end portion as a fulcrum.

[0012] According to the present invention configured in this manner, the cover member can be opened and closed easily, and the urine collection device can be handled more easily when pulling it out through the slit in the front body while wearing underwear, or when discharging urine from the urine collection device. Also, the urine collection device can be seen easily from above when discharging urine collected in the urine collection device into a urinal while standing.

[0013] In the present invention, the underwear preferably comprises a retaining member which is provided on the outer surface of the front body or on the inner surface of the cover member and which retains the tip of the urine collection device arranged on the outer side of the front body.

[0014] According to the present invention thus configured, the holding member restricts the left-right movement of the tip of the urine collection device, making it possible to hold the urine collection device more stably.

[0015] In the present invention, the underwear preferably comprises a movable fabric arranged on the inner surface of the cover member, the portion of the movable fabric that comes into contact with the urine collection device being capable of sliding up and down relative to the inner surface of the cover member.

[0016] According to the present invention configured in this way, the urine collection device in contact with the movable fabric can slide up and down relative to the cover member together with the movable fabric. Therefore, when the wearer walks or sits down or stands up, the movement of the cover member is not directly transmitted to the urine collection device, and it is possible to prevent the urine collection device from falling off the penis and causing leakage.

[0017] In the present invention, the cover member and the movable fabric are preferably woven fabrics, and the front, back, and direction of the fabric forming the cover member and the front, back, and direction of the fabric forming the movable fabric are determined so that the coefficient of friction in the vertical direction between the inner surface of the cover member and the outer surface of the movable fabric is minimized.

[0018] According to the present invention configured in this way, the contact surfaces of the cover member and the movable fabric slide easily against each other in the vertical direction. As a result, when the wearer walks or sits down or stands up, the movement of the cover member is not directly transmitted to the urine collection device, and it is possible to more reliably prevent the urine collection device from slipping off the penis and causing leakage.

[0019] In the present invention, the cover member and the movable fabric are preferably made of woven fabric, and a low-friction coating is applied to the fibers of the fabric forming the cover member and the fibers of the fabric forming the movable fabric.

[0020] According to the present invention configured in this way, the contact surfaces of the cover member and the movable fabric slide easily against each other in the vertical direction. As a result, when the wearer walks or sits down or stands up, the movement of the cover member is not directly transmitted to the urine collection device, and it is possible to more reliably prevent the urine collection device from slipping off the penis and causing leakage.

[0021] In the present invention, preferably, the inner surface of the cover member and the outer surface of the movable fabric are provided with a low-friction coating.

[0022] According to the present invention configured in this way, the contact surfaces of the cover member and the movable fabric slide easily against each other in the vertical direction. As a result, when the wearer walks or sits down or stands up, the movement of the cover member is not directly transmitted to the urine collection device, and it is possible to more reliably prevent the urine collection device from slipping off the penis and causing leakage.

[0023] In the present invention, the underwear preferably comprises a crotch portion located between the wearer's crotch and a back portion extending downward from the waist portion on the wearer's back, and an opening for exposing the anal area in a position in the crotch portion and / or the back portion corresponding to the wearer's anal area.

[0024] According to the present invention configured in this manner, the anus can be exposed through the opening, so that defecation is possible through the opening while wearing the underwear holding the urine collection device. This eliminates the need to remove the underwear and hold the urine collection device with the hand or remove the urine collection device when defecation, improving convenience when defecation.

[0025] In the present invention, the opening is preferably openable and closable.

[0026] According to the present invention thus configured, by making the opening openable and closable, the anus area can be covered by the underwear except when defecation is being performed.

[0027] In the present invention, the underwear preferably has leg fixing belts that can be fixed to the wearer's thighs and are connected to the lower part of the front body, and does not have a member that covers the wearer's anus.

[0028] According to the present invention configured as described above, since the underwear does not have a member covering the wearer's anus, the wearer can defecate while wearing the underwear holding the urine collection device, and there is no need to take off the underwear to hold the urine collection device with one's hand or to remove the urine collection device when defecation occurs, improving convenience when defecation occurs. In addition, by wearing a diaper over the underwear, the wearer can defecate into the diaper while wearing the underwear even when he or she is unable to go to the toilet by himself or herself or is unable to go to the toilet for an extended period of time. In addition, the movement of the lower part of the front body is restricted by the leg fixing belt fixed to the wearer's thighs, so that the lower part of the front body can be made to fit closely to the wearer's body and follow the movement of the body even without a crotch part or a back body.

[0029] In the present invention, the underwear preferably includes a connecting belt connecting the waist portion and the leg fixing belts.

[0030] According to the present invention configured in this manner, by connecting the waist portion and the leg fixing belt with a connecting belt, the position of the leg fixing belt can be stabilized and the lower part of the front body connected to the leg fixing belt can more reliably follow the movement of the body.

[0031] In the present invention, the cover member is preferably formed from an elastic material that is stretchable in response to the expansion of the urine collection device.

[0032] According to the present invention thus configured, the cover member can cover and hold the urine collection device without compressing it. Effect of the Invention

[0033] According to the underwear of the present invention, it is possible to provide underwear suitable for use by a male wearer who wears a urine collection device, which has a flexible and extensible tubular main body and a hollow portion formed in the main body, on his penis.

[0035] Below, underwear according to embodiments of the present invention will be described with reference to the accompanying drawings. In all drawings for describing each embodiment, the same components are generally given the same reference numerals, and repeated description thereof will be omitted. In addition, although each embodiment and modified example are described independently, this does not exclude the underwear being constructed by combining each of the components.

[0036] The underwear of this embodiment is intended for use by a wearer who wears a urine collection device developed by the inventors of the present application on their penis, as described in International Publication No. WO 2023 / 013492.

[0037] The urine collection device has a cylindrical main body made of a flexible and extensible material (e.g., an elastomer having a hardness of 20 degrees or less according to durometer type E in accordance with "JIS K 6253" and an elongation rate of 70% or more), and a hollow part formed in the main body. The hollow part is provided with an introduction part that opens at one end side (base end side) of the main body part to introduce urine, a collection part that is formed continuously from the introduction part and stores urine, and a discharge part that is formed continuously from the collection part and opens at the other end side (tip side) of the main body part to discharge urine. For example, the main body part has a total length of 15 cm and a diameter of 6 cm when no urine is stored, and when urine is introduced into the collection part, the main body part can expand and deform in the radial direction according to the amount of urine collected. In addition, a closing part (e.g., a pinch that closes the discharge part by pinching the tip of the main body part) for closing the discharge part is provided at the tip of the urine collection device.

[0038] [First embodiment] [Underwear configuration] Next, the configuration of the underwear according to the first embodiment of the present invention will be specifically described with reference to Figs. 1 to 7. Fig. 1 is a front view of the underwear according to the first embodiment, showing a state in which the cover member is closed (closed state). Fig. 2 is a front view of the underwear according to the first embodiment, showing a state in which the cover member is open (open state). Fig. 3 is a cross-sectional view taken along line III-III in Fig. 1, showing a side cross-sectional view of the underwear according to the first embodiment. Fig. 4 is a plan view showing the inner surface 14A of the cover member 14 of the underwear according to the first embodiment. Fig. 5 is a top view of the cover member according to the first embodiment. Fig. 6 is a front view of the underwear according to the first embodiment, showing a state before the urine collection device collects and stores urine. Fig. 7 is a front view of the underwear according to the first embodiment, showing a state after the urine collection device collects and stores urine. In Figs. 3, 6 and 7, the state in which the urine collection device configured as described above is worn on the penis of a male wearer is illustrated by imaginary lines (two-dot chain lines).

[0039] In each drawing, the front of the wearer when the underwear is worn by the wearer is the front of the underwear, and the rear of the wearer is the rear of the underwear. In addition, the left-right direction of the wearer when the underwear is worn by the wearer (the direction perpendicular to the front-to-back direction of the underwear) is referred to as the width direction. Furthermore, the surface of the underwear facing the body when worn by the wearer is referred to as the inner surface, and the surface facing the outside of the body (the surface opposite to the inner surface) is referred to as the outer surface.

[0040] The underwear 1 illustrated in the first embodiment is boxer shorts type underwear, however, the present invention can also be applied to underwear of other shapes such as briefs type, trunks type, spats type, etc.

[0041] 1 to 3, underwear 1 comprises a waist section 2 that can be fixed around the waist of a wearer, a front body section 4 that extends downward from the waist section 2 on the wearer's abdominal side, a crotch section 6 that is located between the wearer's legs, and a back body section 8 that extends downward from the waist section 2 on the wearer's back side. The front body section 4, crotch section 6, and back body section 8 can be made of natural fibers such as cotton, chemical fibers such as polyester, or a woven fabric of a blend of these fibers.

[0042] A slit 10 extending in the vertical direction is formed in the center of the front body 4. The slit 10 has a length that allows the urine collection tool C to be inserted and removed. Specifically, the slit 10 has a length at least equal to or greater than the diameter of the urine collection tool C. The total length of the urine collection tool C varies depending on the amount of collected urine. Specifically, the total length is shortest when the urine collection tool C is empty and does not store urine, and is longest when the urine collection tool C stores the maximum amount of urine. Therefore, for example, the slit 10 may have a length equal to or greater than the total length of the urine collection tool C when it is empty and does not store urine. Also, it is desirable to use a highly extensible material for the front body 4 so that the slit 10 can be opened wide to allow the urine collection tool C to pass through even when the urine collection tool C expands in the width direction due to storing urine. Also, one edge of the slit 10 and the other edge are formed to overlap each other front and rear. As a result, the urine collection device C is placed in front of the front body 4 through the slits 10 and then the slits 10 are closed, reliably preventing the urine collection device C from coming into contact with the wearer's body. In addition, because the slits 10 overlap, the slits 10 do not open even if the fabric of the front body 4 is stretched due to stretching caused by the abdominal area, preventing the urine collection device C from directly touching the skin.

[0043] In addition, a through hole 12 through which the penis can be inserted is formed at the lower end of the slit 10 in the front body 4. The diameter of the through hole 12 is formed to be equal to or larger than the outer diameter of the penis, for example.

[0044] A cover member 14 is provided in front of the front body 4, which can be opened and closed between a closed state in which the urine collection device C arranged on the outside of the front body 4 is covered from the outside, and an open state in which the urine collection device C is exposed. The cover member 14 holds the urine collection device C arranged in front of the front body 4 through the slit 10. The cover member 14 is formed in a substantially trapezoidal shape, and the width of the upper end is wider than the width of the lower end, but the width of the upper end may be equal to the width of the lower end or narrower than the width of the lower end. The size of the cover member 14 in the vertical direction and the width direction is large enough to cover the entire urine collection device C expanded by collecting urine from the outside. The cover member 14 is formed of a stretchable material that can stretch in response to the expansion of the urine collection device C, for example, a woven fabric containing polyurethane elastic fiber with excellent stretchability. Furthermore, the front and back and the direction of the woven fabric forming the cover member 14 are determined so that the coefficient of friction in the vertical direction between the inner surface 14A of the cover member 14 and the outer surface of the movable fabric described later is minimized.

[0045] The lower end of the cover member 14 is joined to the front body 4 at a seam 18 below the through hole 12. Furthermore, hook-and-loop fasteners 16 are provided on the inner side of both widthwise ends of the cover member 14 facing the front body 4, and the cover member 14 can be detached from the hook-and-loop fasteners 16 attached to the corresponding positions on the outer side of the front body 4. This allows the cover member 14 to be opened and closed vertically with the lower end as a fulcrum. In the closed state, both widthwise ends of the cover member 14 are fixed to the front body 4 by the hook-and-loop fasteners 16, so that the urine collection device C is held between the cover member 14 and the front body 4, and the left and right movement and widthwise expansion of the urine collection device C are restricted by the left and right hook-and-loop fasteners 16.

[0046] A retaining member 20 is provided at the upper center of the inner surface 14A of the cover member 14, for retaining the tip (discharge portion) of the urine collection device C arranged on the outside of the front body 4. The retaining member 20 is formed into a pocket shape that is open downwards, for example, by folding back the upper end of the fabric constituting the cover member 14 inward and sewing together locations a specified distance to the left and right from the center. As shown in Figures 3, 6 and 7, by inserting the tip of the urine collection device C from below into the retaining member 20, the left and right movement of the tip of the urine collection device C is restricted, and the urine collection device C can be held more stably.

[0047] In addition, a movable fabric 22 is provided below the holding member 20 on the inner surface 14A of the cover member 14. Both ends of the movable fabric 22 in the width direction are fixed to the inner surface 14A of the cover member 14, and the central part of the movable fabric 22, i.e., the part of the movable fabric 22 that contacts the urine collection device C, is slidable up and down relative to the inner surface 14A of the cover member 14. The movable fabric 22 is formed of a woven fabric made of a stretchable material, just like the cover member 14. In addition, the front and back and the direction of the woven fabric forming the movable fabric 22 are determined so that the coefficient of friction in the vertical direction between the outer surface 22A of the movable fabric 22, i.e., the surface 22A of the movable fabric 22 facing the cover member 14, and the inner surface 14A of the cover member 14 is minimized. As a result, the contact surfaces of the cover member 14 and the movable fabric 22 easily slide against each other in the vertical direction, so that the urine collection device C in contact with the movable fabric 22 can slide up and down relative to the cover member 14 together with the movable fabric 22. Therefore, when the wearer walks or sits down or stands up, the movement of the cover member 14 is not directly transmitted to the urine collection device C, and the urine collection device C can be prevented from coming off the penis and causing leakage.

[0048] When a wearer wearing the urine collection device C puts on the underwear 1, first, the wearer puts on the urine collection device C, then puts on the underwear 1 with the cover member 14 open, and places the urine collection device C in front of the front body 4 through the slit 10, while passing the penis through the hole 12 of the front body 4. Alternatively, after putting on the underwear 1, the penis may be passed through the hole 12 of the front body 4, and the urine collection device C may be put on in that state.

[0049] Next, while closing the cover member 14 with its lower end as a fulcrum, the tip of the urine collection device C is inserted from below the holding member 20, and the hook-and-loop fasteners 16 on both ends of the cover member 14 are pressed against the hook-and-loop fasteners 16 on the front body 4 to fix the cover member 14 in place (the state shown in FIG. 6). This ensures that the urine collection device C is held securely between the front body 4 and the cover member 14.

[0050] When the wearer excretes urine in the state shown in Fig. 6, the collecting part in the center of the urine collection device C expands to collect and hold the urine therein, as shown in Fig. 7. As described above, the cover member 14 is large enough to cover the entire urine collection device C that has expanded by collecting urine from the outside, and is stretchable, so that it can hold the urine collection device C without compressing it. In addition, since both ends in the width direction of the cover member 14 are fixed to the front body 4 by hook-and-loop fasteners 16 and the tip of the urine collection device C is held by the holding member 20, the urine collection device C is prevented from falling left or right and being exposed to the outside from the cover member 14.

[0051] When discharging urine collected in the urine collection device C, the wearer stands in front of a urinal, opens the cover member 14 forward, pulls the tip of the urine collection device C out of the holding part of the cover member 14 and points it towards the urinal, opens the closure part provided at the tip of the urine collection device C, and discharges urine from the discharge part into the urinal. In other words, just like normal urination, urine can be discharged into the urinal while standing without having to remove trousers or underwear 1, making it extremely easy to discharge.

[0052] [Second embodiment] Next, the configuration of underwear according to a second embodiment of the present invention will be described with reference to Figs. 8 to 10. Fig. 8 is a front view of the underwear according to the second embodiment, showing a state in which the cover member is closed (closed state). Fig. 9 is a cross-sectional view taken along line IX-IX in Fig. 8, showing a side cross-sectional view of the underwear according to the second embodiment. Fig. 10 is a front view of the underwear according to the second embodiment, showing a state in which the cover member is open (open state). In Fig. 9, the state in which the urine collection device configured as described above is worn on the penis of a male wearer is illustrated by an imaginary line (two-dot chain line).

[0053] The underwear 1 exemplified in the second embodiment comprises a waist part 2 that can be fixed around the waist of a wearer, and a front body part 4 that extends downward from the center of the waist part 2 on the abdominal side of the wearer. The front body part 4 is large enough to separate the entire urine collection device C that expands by collecting urine from the wearer's body. For example, as shown in Figs. 8 to 10, the front body part 4 is formed in a substantially trapezoidal shape that is slightly larger than the cover member 14. Other configurations of the front body part 4 are similar to those of the front body part 4 in the first embodiment, and therefore detailed explanations will be omitted.

[0054] 8 to 10, the underwear 1 of the second embodiment is different from the underwear 1 of the first embodiment in that it does not include any member for covering the anus of the wearer, such as the crotch portion or the back body. Instead, the underwear 1 of the second embodiment includes leg fixing belts 30 for allowing the lower part of the front body 4 to follow the movement of the wearer's body.

[0055] Specifically, the underwear 1 includes leg fixing belts 30 that can be fixed around the left and right thighs of the wearer. Both ends of the leg fixing belts 30 are provided with hook-and-loop fasteners 32, and the leg fixing belts 30 can be fixed by the hook-and-loop fasteners 32 in a state where the leg fixing belts 30 are wrapped around the thighs. Furthermore, the leg fixing belts 30 are connected to the lower part of the front body 4 by a connecting belt 34. As a result, the movement of the lower part of the front body 4 is restricted by the leg fixing belts 30 fixed to the thighs of the wearer, so that the lower part of the front body 4 can be made to fit closely to the body of the wearer and follow the movement of the body even without a crotch part or a back body.

[0056] A cover member 14 is provided in front of the front body 4, which can be opened and closed between a closed state in which the urine collection device C arranged on the outside of the front body 4 is covered from the outside, and an open state in which the urine collection device C is exposed, similar to the cover member 14 of the first embodiment.

[0057] A slit 36 ​​extending in the vertical direction is formed in the center of the cover member 14. The slit 36 ​​has a length that allows the tip of the urine collection device C to be inserted and removed. When the underwear 1 of the second embodiment is worn inside undergarments such as ordinary pants, briefs, trunks, etc., it is possible to remove the tip of the urine collection device C from the slit 36 ​​and discharge urine from the discharge part of the urine collection device C while wearing the underwear 1 and keeping the cover member 14 in a closed state. Other configurations of the cover member 14 are similar to those of the cover member 14 of the first embodiment, so a detailed description will be omitted.

[0058] As in the first embodiment, in the underwear 1 of the second embodiment, the wearer may first put on the urine collection device C and then put on the underwear 1, and place the urine collection device C in front of the front body 4 through the slit 10 and pass the penis through the hole 12 of the front body 4, or may put on the underwear 1, and then pass the penis through the hole 12 of the front body 4 and put on the urine collection device C in that state.

[0059] After putting on the underwear 1 and the urine collection device C, the tip of the urine collection device C is inserted from below the holding member 20, and the cover member 14 is closed and fixed with the hook-and-loop fastener 16. As a result, in the underwear 1 of the second embodiment as well, the urine collection device C is securely held between the front body 4 and the cover member 14.

[0060] In addition, the underwear 1 of the second embodiment does not have a crotch portion or a back portion, so the wearer's anus is not covered by the underwear 1. Therefore, the wearer can defecate while wearing the underwear 1 holding the urine collection device C, and there is no need to take off the underwear 1 and hold the urine collection device C with hands or remove the urine collection device C when defecation is required, improving convenience when defecation is required. In addition, by wearing a diaper over the underwear 1 of the second embodiment, the wearer can defecate into the diaper while wearing the underwear 1 even when he or she is unable to go to the toilet by himself or when he or she is unable to go to the toilet for a long period of time.

[0061] [Variations] Next, modified examples of each embodiment will be described. In each of the above-mentioned embodiments, the retaining member 20 is formed in a pocket shape that opens downward, but it may be formed in a belt shape that extends in the width direction. In this case, both ends of the belt-shaped retaining member 20 are fixed to the inner surface 14A of the cover member 14, and a gap is formed between the center of the retaining member 20 and the cover member 14. By inserting the tip of the urine collection device C from below into this gap, the retaining member 20 restricts the left-right movement of the urine collection device C.

[0062] Furthermore, in each of the above-described embodiments, the holding member 20 is provided on the inner surface 14A of the cover member 14, but the holding member 20 may be provided in the upper center of the front body 4.

[0063] In the above-described embodiments, the cover member 14 is formed in a substantially trapezoid shape and the lower end is connected to the front body 4. However, the shape and the fixed position of the cover member 14 may be changed as long as the urine collection device C can be held between the cover member 14 and the front body 4 by fixing both ends of the cover member 14 in the width direction to the front body 4 in the closed state. For example, the cover member 14 may be configured so that one of the left end or the right end is connected to the front body 4 and the other end is detachably attached to the front body 4 by a hook-and-loop fastener 16, so that the cover member 14 can be opened and closed left and right. Alternatively, the cover member 14 may be configured so that the upper end is fixed to the front body 4 and the cover member 14 can be opened and closed up and down with the upper end as a fulcrum. However, from the viewpoint of protecting the urine collection device C and taking into consideration the embarrassment of the wearer, it is preferable that the cover member 14 covers the through-holes 12 and the urine collection device C from the outside.

[0064] In addition, the woven fibers forming the cover member 14 and the woven fibers forming the movable fabric 22 may be coated with a low-friction coating, and the inner surface 14A of the cover member 14 and the outer surface 22A of the movable fabric 22 may be coated with a low-friction coating. Examples of low-friction coatings include fluororesin coatings and silicone coatings. This makes it easier for the contact surfaces of the cover member 14 and the movable fabric 22 to slide against each other in the vertical direction, so that when the wearer walks or sits down or stands up, the movement of the cover member 14 is not directly transmitted to the urine collection device C, and it is possible to more reliably prevent the urine collection device C from coming off the penis and causing leakage.

[0065] In the above-mentioned first embodiment, the underwear 1 is described as having the waist portion 2, the front body 4, the crotch portion 6, and the back body 8. However, an opening for exposing the anal area may be provided in the crotch portion 6 and / or the back body 8 at a position corresponding to the wearer's anal area. For example, an openable / closable slit may be provided in the crotch portion 6 and / or the back body 8 at a position corresponding to the wearer's anal area. Alternatively, a hole may be formed in the crotch portion 6 and / or the back body 8 at a position corresponding to the wearer's anal area, and a cover that can be opened and closed between a state in which the hole is covered and a state in which the hole is exposed may be provided. This allows defecation through the opening while wearing the underwear 1 holding the urine collection device C, and there is no need to take off the underwear 1 to hold the urine collection device C with a hand or to remove the urine collection device C when defecation, improving convenience when defecation.

[0066] In addition, in the above-mentioned second embodiment, it was explained that the leg fixing belt 30 can be wrapped around the thigh and fixed with the hook-and-loop fastener 32, but the leg fixing belt 30 may be formed into a ring shape using an elastic material such as a rubber band, and the leg fixing belt 30 may be fixed to the thigh by its elasticity.

[0067] In the above-mentioned second embodiment, the leg fixing belt 30 is connected to the lower part of the front body 4 by the connecting belt 34. However, the leg fixing belt 30 may be directly connected to the lower part of the front body 4 without the connecting belt 34. Also, a connecting belt may be added to connect the side or rear part of the waist part 2 to the leg fixing belt 30. For example, as shown in Figs. 11 and 12, a connecting belt 38 may be added to connect the left and right side parts of the waist part 2 to the left and right side parts of the leg fixing belt 30. In this way, by connecting the waist part 2 to the leg fixing belt 30 by the connecting belt 38, the position of the leg fixing belt 30 can be stabilized, and the lower part of the front body 4 connected to the leg fixing belt 30 can be more reliably moved according to the movement of the body.

[0068] [Action and Effects] Next, the functions and effects of the underwear 1 according to each of the above-described embodiments and modifications will be described.

[0069] The front body 4 of the underwear 1 is formed with a slit 10 that extends in the vertical direction and has a length allowing the urine collection device C to be inserted and removed, and a through-hole 12 that is located at the lower end of the slit 10 and through which the penis can be inserted. This allows the underwear 1 to be easily put on and taken off while the urine collection device C is worn, or the urine collection device C can be put on and taken off with the penis passed from the inside to the outside of the front body 4 through the through-hole 12, and prevents the urine collection device C arranged on the outside of the front body 4 from coming into contact with the wearer's body when the underwear 1 is being worn.

[0070] The cover member 14 of the underwear 1 can be opened and closed between a closed state in which the urine collection device C arranged on the outside of the front body 4 is covered from the outside, and an open state in which the urine collection device C is exposed, and since it is fixed to the front body 4 in the closed state, the urine collection device C can be securely held between the cover member 14 and the front body 4 in the closed state. Furthermore, when the cover member 14 is in the open state, the urine collected in the urine collection device C can be discharged into a urinal while standing, with the urine collection device C still on, in the same way as normal urination, without having to remove the trousers and underwear 1, and discharge can be easily performed. Therefore, the urine collection device C can be used appropriately while reducing the burden on the wearer.

[0071] Furthermore, because both widthwise ends of the cover member 14 are detachably attached to the front body 4, the widthwise ends of the cover member 14 can be removed from the front body 4 to open the cover member 14 wide, making it easier to handle the urine collection device C when pulling the urine collection device C outward through the slits 10 in the front body 4 or when discharging urine from the urine collection device C while wearing the underwear 1. Furthermore, by attaching both widthwise ends of the cover member 14 to the front body 4 in the closed state, the urine collection device C can be prevented from falling left or right or expanding widthwise and becoming exposed to the outside from the cover member 14.

[0072] Moreover, since the cover member 14 can be opened and closed with its lower end as a fulcrum, the cover member 14 can be opened and closed easily, and the urine collection device C can be handled more easily when pulling the urine collection device C outward from the slit 10 in the front body 4 while wearing the underwear 1, or when discharging urine from the urine collection device C. Furthermore, visibility of the urine collection device C is good when viewed from above when discharging urine collected in the urine collection device C into a urinal while standing.

[0073] In addition, the garment is provided with a retaining member 20 which is provided on the outer surface of the front body 4 or the inner surface 14A of the cover member 14 and holds the tip of the urine collection device C arranged on the outside of the front body 4. This restricts the left-right movement of the tip of the urine collection device C by the retaining member 20, thereby enabling the urine collection device C to be held more stably.

[0074] In addition, the cover member 14 is provided with a movable fabric 22, the portion of which that is disposed on the inner surface 14A of the cover member 14 and that is in contact with the urine collection device C, is capable of sliding up and down relative to the inner surface 14A of the cover member 14, so that the urine collection device C that comes into contact with the movable fabric 22 can slide up and down together with the movable fabric 22 relative to the cover member 14. Therefore, when the wearer walks or sits down or stands up, the movement of the cover member 14 is not directly transmitted to the urine collection device C, and it is possible to prevent the urine collection device C from falling off the penis and causing leakage.

[0075] Furthermore, the front / back and direction of the fabric forming the cover member 14 and the front / back and direction of the fabric forming the movable fabric 22 are determined so that the coefficient of friction in the vertical direction between the inner surface 14A of the cover member 14 and the outer surface 22A of the movable fabric 22 is minimized, so that the contact surfaces of the cover member 14 and the movable fabric 22 tend to slide against each other in the vertical direction. This prevents the movement of the cover member 14 from being directly transmitted to the urine collection device C when the wearer walks or sits down or stands up, and more reliably prevents the urine collection device C from slipping off the penis and causing leakage.

[0076] In addition, since a low-friction coating is applied to the woven fibers forming the cover member 14 and the woven fibers forming the movable fabric 22, or a low-friction coating is applied to the inner surface 14A of the cover member 14 and the outer surface 22A of the movable fabric 22, the contact surfaces of the cover member 14 and the movable fabric 22 tend to slide against each other in the vertical direction. This prevents the movement of the cover member 14 from being directly transmitted to the urine collection device C when the wearer walks or sits down or stands up, and more reliably prevents the urine collection device C from coming off the penis and causing leakage.

[0077] Furthermore, since the cover member 14 is made of a stretchable material that can stretch in response to the expansion of the urine collection device C, the cover member 14 can cover and hold the urine collection device C without compressing it.

[0078] Furthermore, if an opening for exposing the anal area is provided in the crotch portion 6 and / or back body 8 of the underwear 1 of the first embodiment at a position corresponding to the wearer's anal area, the anal area can be exposed through the opening, and therefore defecation is possible through the opening while wearing the underwear 1 holding the urine collection device C, and there is no need to take off the underwear 1 and hold the urine collection device C with one's hand or remove the urine collection device C when defecation is required, improving convenience when defecation is performed. Furthermore, by making the opening openable, the anal area can be covered by the underwear 1 except when defecation is being performed.

[0079] In addition, since the underwear 1 of the second embodiment does not have a member covering the anus of the wearer, such as the crotch part or the back part, the wearer can defecate while wearing the underwear 1 holding the urine collection tool C, and there is no need to take off the underwear 1 to hold the urine collection tool with hands or remove the urine collection tool C when defecation is required, improving convenience during defecation. In addition, by wearing a diaper over the underwear 1 of the second embodiment, the wearer can defecate into the diaper while wearing the underwear 1 even when he or she cannot go to the toilet by himself or herself or when he or she cannot go to the toilet for a long time. In addition, the movement of the lower part of the front body 4 is restricted by the leg fixing belt 30 fixed to the wearer's thighs, so that the lower part of the front body 4 can be made to adhere closely to the wearer's body and follow the movement of the body even without the crotch part or the back body.

[0080] In addition, by connecting the waist portion 2 and the leg fixing belt 30 with the connecting belt 38, the position of the leg fixing belt 30 can be stabilized, and the lower part of the front body 4 connected to the leg fixing belt 30 can more reliably follow the movement of the body.

[0081] The embodiments and modifications of the present invention can be appropriately combined and implemented. The above-mentioned embodiments and modifications are merely examples for explaining the present invention, and the present invention is not limited to these embodiments and modifications. The present invention can be implemented in various forms without departing from the gist of the present invention. [Explanation of symbols]
