Description

Technical Field

[0001] The present invention relates to men's underwear.

Background Art

[0002] Conventionally, trunks-type and boxer-type men's underwear have been known. Since the fabric of such men's underwear extends to the thigh area, it is possible to reduce the stuffiness between both thighs and the discomfort caused by rubbing. However, since conventional men's underwear does not have a structure for holding the male genitalia, there is a risk that the scrotum and the skin of the crotch area adhere closely and become stuffy, causing discomfort.

[0003] In order to solve such problems, a technique has been developed that uses a mesh fabric and aims to ensure a dry state by relying on natural ventilation. For example, the men's underwear of Patent Document 1 is formed by sewing both side portions and the lower edge of a covering cloth made of a substantially inverted triangular stretchable mesh fabric to both side portions and the lower edge portion of the front body so as to provide an opening at the lower center of the front body and cover the front of the opening. With such a configuration, it is said that the air permeability of the lower front part of the front body is good, it is not easily stuffy, and it is also convenient for urination.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in conventional men's underwear including the above-mentioned Patent Document 1, the male genitalia and the surrounding skin are not completely isolated. Therefore, sweating, stuffiness, discomfort caused by them, and rubbing between the male genitalia and the surrounding skin, which are caused by environmental factors such as high temperature and high humidity, physical factors such as obesity, exercise factors such as walking, and postural factors at rest such as long-term sitting, lying on the back, and standing up, cannot be solved.

[0006] Therefore, the present invention has been developed in view of the above problems, and an object thereof is to provide men's underwear that solves the problems in the above-mentioned issues by isolating the male genitalia from the surrounding skin.

Means for Solving the Problems

[0007] In order to achieve the above object, the men's underwear of the present invention includes a back body corresponding to the buttocks, a front body corresponding to the lower abdomen, a covering portion covering the male genitalia, and left and right close-contact portions arranged on the left and right of the covering portion and extending along the inguinal region from the lower abdomen toward the crotch and closely contacting. The left and right close-contact portions are composed of a fabric having less stretchability than the back body, the front body, and the covering portion, and the left and right close-contact portions are double-constructed by a fabric having less stretchability and a fabric having a cooling effect with at least a part thereof being in an accordion shape.

[0008] Furthermore, the men's underwear of another form of the present invention includes a back body corresponding to the buttocks, a front body corresponding to the lower abdomen, a covering portion covering the male genitalia, and left and right close-contact portions arranged on the left and right of the covering portion and extending along the inguinal region from the lower abdomen toward the crotch and closely contacting. The left and right close-contact portions are composed of a fabric having less stretchability than the back body, the front body, and the covering portion, and only a part of the left and right close-contact portions is sewn to the front body and / or the covering portion arranged on the left and right.

Effects of the Invention

[0009] Thus, the men's underwear of the present invention includes a back body, a front body, a covering portion, and left and right close-contact portions. The left and right close-contact portions are made of a fabric with less stretchability compared to the back body, the front body, and the covering portion. The left and right close-contact portions are double-constructed of a fabric with less stretchability and a fabric having a cooling effect with at least a part thereof being in an accordion shape. With such a configuration, by directly or indirectly contacting the fabric having the cooling effect of the left and right close-contact portions, sweating, stuffiness, and the discomfort caused by them can be suppressed.

[0010] Also, the men's underwear of another form of the present invention includes a back body, a front body, a covering portion, and left and right close-contact portions. The left and right close-contact portions are made of a fabric with less stretchability compared to the back body, the front body, and the covering portion. Only a part of the left and right close-contact portions is sewn to the front body and / or the covering portion arranged on the left and right. With such a configuration, ventilation can be achieved through the unsewn portions (gaps), so sweating, stuffiness, and the discomfort caused by them can be suppressed. In addition, due to the presence of the unsewn portions, the influence of the close-contact portions being pulled by the fabrics of the front body and the covering portion arranged on the left and right can be reduced more, so the adhesion force to the groin portion increases, and the isolation effect is further improved to suppress discomfort.

Mode for Carrying Out the Invention

[0012] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the components described in the following examples are illustrative, and are not intended to limit the technical scope of the present invention thereto.

Examples

[0013] (Configuration) First, in this example, the men's underwear 1 provided with the close contact parts (14, 15) without using a cooling material will be described with reference to FIGS. 1 to 4. The men's underwear 1 of this example is a so-called boxer brief (boxer pants) as shown in FIGS. 1 and 2. However, the present invention is also applicable to other types of men's underwear (for example, briefs, midway briefs, etc.). This men's underwear 1 is mainly composed of the peripheral parts 14, 15, 16 of the male genitalia using materials with strong wearing pressure and tightening, and the other parts 11 to 13, 17 to 19.

[0014] More specifically, the men's underwear 1 includes a back body 19 that covers the buttocks, a right front body 12 and a left front body 13 as front bodies that cover the lower abdomen, a covering part 17 that covers the male genitalia, a right close contact part 14 and a left close contact part 15 that are arranged on the left and right of the covering part 17 and are in close contact with the groin (the base of the thigh), a pressing part 16, and a crotch gusset 18.

[0015] The right close contact part 14, the left close contact part 15, and the pressing part 16 around the male genitalia are formed of a fabric with low stretchability and thus strong wearing pressure and tightening compared to the peripheral parts such as the front bodies 12, 13, the covering part 17, the crotch gusset 18, and the back body 19.

[0016] The left and right close contact parts 14 and 15 extend along the groin from the lower abdomen toward the crotch. The pressing part 16 is arranged at the crotch part (a position corresponding to the lower part of the male genitalia).

[0017] In the vicinity of the center of the front, the pressing portion 16 is formed in a cylindrical shape and is arranged horizontally so as to open in the left-right direction. Then, both left and right end portions of the pressing portion 16 are stitched to the inner portions of the close contact portions 14 and 15. Further, the outer left and right portions of the covering portion 17 are stitched to the inner portions of the close contact portions 14 and 15, the lower end portion of the covering portion 17 is stitched to the upper end portion of the pressing portion 16, the upper end portions of the crotch gussets 18 are stitched to the lower end portions of the close contact portions 14 and 15, and the lower end portion of the pressing portion 16 is stitched.

[0018] In addition, on the front surface, the lower end portion of the waist rubber 11, the upper end portions of the left and right front bodies 12 and 13, the upper end portions of the left and right close contact portions 14 and 15, and the upper end portion of the covering portion 17 are stitched. Also, the inner portions of the left and right front bodies 12 and 13 are stitched to the outer portions of the left and right close contact portions 14 and 15. Further, the lower inner portions of the left and right front bodies 12 and 13 are stitched to the outer left and right portions of the crotch gussets 18.

[0019] On the back surface, the lower end portion of the waist rubber 11 is stitched to the upper end portion of the back body 19, and the lower end portion of the back body 19 is stitched to the upper end portion and the outer both end portions of the crotch gussets 18.

[0020] On the left and right side surfaces, the back body 19 and the front bodies 12 and 13 are stitched at their respective outer portions.

[0021] Therefore, the pressure applied to the male genitalia from the left and right by the close contact portions 14 and 15 made of a material having a high wearing pressure and a high tightening effect, and similarly, due to the small elasticity, the pressure applied to the male genitalia from below by the pressing portion 16 made of a material having a high wearing pressure and a high tightening effect, the entire male genitalia automatically pushed forward is covered by the covering portion 17, forming a form that isolates the male genitalia from the skin around the male genitalia.

[0022] And, in the male underwear 1 of the present embodiment, the left and right close contact portions 14 and 15 are constituted by a fabric having a cold feeling effect together with a high wearing pressure and a high tightening effect. Here, the fabric having a cold feeling effect is a so-called "contact cold feeling material", which refers to a fabric that feels cool when touched.

[0023] As contact-cool feeling materials, among chemical fibers, it is known that rayon and cupra have excellent properties in this contact-cool feeling. As fabrics (materials), specifically, core-sheath composite fibers using polyester for the core and everal (a composite resin of polyethylene resin and polyvinyl alcohol resin) for the sheath are known.

[0024] Furthermore, as shown in FIG. 3, the left and right close-contact parts 14 and 15 of this embodiment can also be formed into a double structure by an outer fabric 141 with low stretchability and an inner fabric 142 with a cooling effect. However, conversely, as will be described later, the outer side can be a fabric with a cooling effect, and the inner side can be a fabric with low stretchability.

[0025] That is, when the stretchability of the fabric 142 with a cooling effect is poor, its stretchability is ensured by forming it in an accordion shape. In addition, as the shape of the inner fabric 142, in addition to the illustrated accordion shape, it may be a wave shape, a zigzag shape, or a folded-back shape. That is, any shape is included as long as it has a margin of a predetermined length in the direction in which the fabric stretches.

[0026] In addition, it is also preferable that the covering part 17 is made of a fabric with high water absorption and quick drying compared to the back body 19, the front bodies 12 and 13, and the close-contact parts 14 and 15.

[0027] (Effect) Next, the effects exhibited by the men's underwear 1 of this embodiment will be listed and described.

[0028] (1) As described above, the men's underwear 1 of this embodiment includes a back body 19 that covers the buttocks, front bodies 12 and 13 that cover the lower abdomen, a covering portion 17 that covers the male genitalia, and left and right close-contact portions 14 and 15 that are arranged on the left and right of the covering portion 17 and are in close contact with the groin. The left and right close-contact portions 14 and 15 are made of a fabric with less stretchability than the back body 19, front bodies 12 and 13, and covering portion 17, thereby strengthening the wearing pressure and tightening. With such a configuration, as shown in FIG. 4, by isolating the male genitalia from the surrounding skin, sweating, stuffiness, discomfort caused by them, and rubbing between the male genitalia and the surrounding skin can be eliminated.

[0029] (2) Further, the left and right close-contact portions 14 and 15 are made of a fabric having a cooling effect. Then, because of the small stretchability, by arranging a fabric with strong wearing pressure and tightening on the close-contact portions 14 and 15, the close-contact portions 14 and 15 made of a fabric with a cooling effect adhere to the groin, so the comfort due to the cooling effect becomes extremely high. That is, instead of simply arranging a fabric with a cooling effect, by applying a fabric with a cooling effect to the close-contact portions 14 and 15 that adhere to the groin due to the small stretchability and the resulting increase in wearing pressure and tightening, the fabric with a cooling effect can surely adhere to the groin with a large area, so that the whole body can be efficiently cooled.

[0030] (3) Furthermore, it is preferable that the left and right close-contact portions 14(15) are composed of an outer fabric 141 with small stretchability and an inner accordion-shaped fabric 142 having a cooling effect. In this way, by making the close-contact portions 14(15) into a double structure, two advantages of stretchability (adhesiveness) and comfort due to the cooling effect can be realized simultaneously. In particular, it is effective to make a double structure when the fabric having a cooling effect has poor stretchability.

[0031] (4) Also, since the covering portion 17 is made of a fabric with high water absorption and quick drying compared to the back body 19, front bodies 12 and 13, and close-contact portions 14 and 15, it is highly effective as a countermeasure against urine leakage and residual urine. In this case, since the male genitalia fit into the covering portion 17, it becomes difficult for urine to leak out to the surroundings, so the effect is even higher.

Example

[0032] Hereinafter, with reference to FIGS. 5 and 6, a men's underwear 1A having adhesion portions 24 and 25 in a form different from that of Example 1 will be described. Note that the same reference numerals will be used to describe the same or equivalent portions as those described in Example 1.

[0033] (Configuration) First, regarding the configuration, the men's underwear 1A of Example 2 has a configuration substantially the same as that of the men's underwear 1 of Example 1 as shown in FIG. 5. That is, the men's underwear 1A of the present embodiment includes a back body 19 that covers the buttocks, a right front body 12 and a left front body 13 as front bodies that cover the lower abdomen, a covering portion 17 that covers the male genitalia, a right adhesion portion 24 and a left adhesion portion 25 that are disposed on the left and right of the covering portion 17 and adhere to the groin, a pressing portion 16, and a crotch gusset 18.

[0034] And the men's underwear 1A of the present embodiment is significantly different from Example 1 in that cooling materials 30 are stored in the left and right adhesion portions 24 and 25. For example, the right adhesion portion 24 (the same applies to the left adhesion portion 25) is composed of double fabrics 241 and 242 as a cylindrical portion configured in a cylindrical shape, and a coolant 30 accommodated inside the cylindrical portion.

[0035] That is, the right adhesion portion 24 is double - configured by an elongated outer fabric 241 and an elongated inner fabric 242 of the same shape, and is configured in a cylindrical shape by sewing both side edges together. Similarly, the left adhesion portion 25 is also double - configured by an elongated outer fabric 251 and an elongated inner fabric 252 of the same shape, and is configured in a cylindrical shape by sewing both side edges together.

[0036] And the cylindrical portions 241, 242, 251, and 252 of the left and right close-contact portions 24, 25 have openings 243, 253 at the upper parts because the upper parts in the worn state are not sewn. Through these openings 243, 253, the coolant 30 can be stored and exchanged. Therefore, by previously cooling a plurality of coolants 30 in a refrigerator or the like and preparing them, it is possible to continuously cool the groin area with the coolant 30 at a low temperature for a long time.

[0037] The coolant 30 is formed in an elongated rod shape, which makes it easy to store in the storage portion. As the coolant 30, commercially available ones can be used, which are composed of water and a highly absorbent polymer and are housed in a polyethylene bag. Of course, a dedicated coolant 30 with a size that is easy to store in the storage portion can also be used.

[0038] (Effect) Next, the effects exhibited by the men's underwear 1A of this embodiment will be listed and explained.

[0039] (1) As described above, the men's underwear 1A of this embodiment includes a back body 19 that covers the buttocks, front bodies 12, 13 that cover the lower abdomen, a covering portion 17 that covers the male genitalia, and left and right close-contact portions 24, 25 that are arranged on the left and right of the covering portion 17 and are in close contact with the groin area. The left and right close-contact portions 24, 25 are made of a fabric with reduced stretchability compared to the back body 19, front bodies 12, 13, and covering portion 17, thereby strengthening the wearing pressure and tightening. This is the same as in Embodiment 1. Therefore, by isolating the male genitalia from the surrounding skin, sweating, stuffiness, the discomfort caused by them, and the rubbing between the male genitalia and the surrounding skin can be eliminated.

[0040] (2) And the left and right close-contact parts 24(25) are composed of double fabrics 241, 242(251, 252) that form a cylindrical part configured in a cylindrical shape, and a coolant 30 housed inside the cylindrical part. With such a configuration, by storing the coolant 30 that has been pre-cooled in a refrigerator or the like in the storage part, the inguinal region can be cooled by the coolant 30. That is, by cooling the inguinal region (the base of the thigh) with the coolant 30 at a low temperature, the blood vessels (arteries and veins) can be cooled, and thus the whole body can be efficiently cooled.

[0041] (3) Further, the double fabrics 241, 242(251, 252) that form the cylindrical parts of the left and right close-contact parts 24, 25 preferably have an opening 243(253) at the upper part in the worn state, and the coolant 30 can be exchanged through the opening 243(253). With such a configuration, since the coolant 30 can be exchanged through the opening 243(253), by preparing a plurality of coolants 30 in advance, the inguinal region - and thus the whole body - can be continuously cooled for a long time.

[0042] Note that since other configurations and effects are substantially the same as those in Example 1, the description thereof is omitted.

Example

[0043] Hereinafter, with reference to FIGS. 7 and 8, a men's underwear 1B provided with close-contact parts 34 and 35 in a form different from those in Examples 1 and 2 will be described. Note that the same reference numerals will be used to describe parts that are the same as or equivalent to those described in Examples 1 and 2.

[0044] (Configuration) Similar to Examples 1 and 2, the men's underwear 1B includes a back body 19 that covers the buttocks, a right front body 12 and a left front body 13 as front bodies that cover the lower abdomen, a covering part 17 that covers the male genitalia, a right close-contact part 34 and a left close-contact part 35 that are arranged on the left and right of the covering part 17 and are in close contact with the inguinal region (the base of the thigh), a pressing upper part 16, and a crotch gusset 18.

[0045] And, the right close contact part 34 and the left close contact part 35 around the male genitalia of the men's underwear 1B of the present embodiment are formed of a fabric with less stretchability, as in the case of the first embodiment, compared with the front body parts 12, 13, the covering part 17, the crotch gusset part 18, and the back body part 19 which are the peripheral parts thereof.

[0046] Furthermore, the left and right close contact parts 34, 35 of the present embodiment are double - configured by fabrics 341, 351 with less stretchability and fabrics 342, 352 having a cooling effect with at least a part being in an accordion shape. Note that "at least a part being in an accordion shape" includes not only the mode in which the whole is in an accordion shape, but also the mode in which only a very small part is in an accordion shape.

[0047] Here, the close contact parts 34, 35 having a two - layer structure may be configured such that, as shown in Fig. 8(a), the inner side is a fabric 341 (351) with less stretchability and the outer side is a fabric 342 (352) having a cooling effect, or conversely, as shown in Fig. 8(b), the outer side is a fabric 341 (351) with less stretchability and the inner side is a fabric 342 (352) having a cooling effect.

[0048] (Function and Effect) Next, the effects exerted by the men's underwear 1B of the present embodiment will be described.

[0049] (1) As described above, the men's underwear 1B of the present embodiment includes a back body part 19 corresponding to the buttocks, front body parts 12, 13 corresponding to the lower abdomen, a covering part 17 covering the male genitalia, and left and right close contact parts 34, 35 arranged on the left and right of the covering part 17 and extending and closely contacting along the inguinal region from the lower abdomen to the crotch. The left and right close contact parts 34, 35 are formed of a fabric with less stretchability compared with the back body part 19, the front body parts 12, 13, and the covering part 17, and the left and right close contact parts 34, 35 are double - configured by a fabric 341 with less stretchability and a fabric 342 having a cooling effect with at least a part being in an accordion shape. With such a configuration, by directly or indirectly contacting the fabric having a cooling effect of the left and right close contact parts, sweating, stuffiness, and the discomfort caused by them can be suppressed.

[0050] In addition, regarding other configurations, operations, and effects, since they are substantially the same as those in the first and second embodiments, the description thereof is omitted.

Embodiment

[0051] Hereinafter, with reference to FIG. 9, a men's undergarment 1C having adhering portions 44 and 45 in a form different from those in the first to third embodiments will be described. Note that, for the description of parts that are the same as or equivalent to those described in the first to third embodiments, the same reference numerals will be used.

[0052] (Configuration) Similar to the first to third embodiments, the men's undergarment 1C includes a back body 19 that covers the buttocks, a right front body 12 and a left front body 13 as front bodies that cover the lower abdomen, a covering portion 17 that covers the male genitalia, right and left adhering portions 44 and 45 that are disposed on the left and right of the covering portion 17 and adhere to the groin (the base of the thigh), a pressing portion 16, and an inseam gusset 18.

[0053] And, the right and left adhering portions 44 and 45 around the male genitalia of the men's undergarment 1C in this embodiment are formed of a fabric with less stretchability compared to the front bodies 12 and 13, the covering portion 17, the inseam gusset 18, and the back body 19, which are the peripheral portions thereof, in the same manner as in the first embodiment.

[0054] Furthermore, as shown in FIG. 9, only a part of the right and left adhering portions 44 and 45 of this embodiment is sewn to the front bodies 12 and 13 and / or the covering portion 17 that are disposed on the left and right. In other words, the right and left adhering portions 44 and 45 have a portion (an ellipse surrounded by a white dotted line in the figure) that is not sewn to the surrounding members, and this portion forms a gap. Of course, it includes the case where only a part of the front bodies 12 and 13 and the right and left adhering portions 44 and 45 are sewn, and only a part of the covering portion 17 and the right and left adhering portions 44 and 45 are sewn, but also includes the case where only a part of either one is sewn.

[0055] More specifically, there is at least a part that is not sewn between the covering part 17 and the adhering part 44 (45), and / or between the adhering part 44 (45) and the front body part 12 (13). Since this part becomes a gap, the breathability inside and outside the underwear can be maintained through the gap. Needless to say, the unsewn part may be concentrated and continuous in one place, or may be dispersed (discrete) in several places.

[0056] (Function and Effect) Next, the effects of the men's underwear 1C of this embodiment will be described.

[0057] (1) As described above, the men's underwear 1C of this embodiment includes a back body part 19 that covers the buttocks, a right front body part 12 and a left front body part 13 as front body parts that cover the lower abdomen, a covering part 17 that covers the male genitalia, right and left adhering parts 44 and 45 that are arranged on the left and right sides of the covering part 17 and adhere to the groin (the base of the thigh), a pressing part 16, and a crotch gusset 18. Among these, the left and right adhering parts 44 and 45 are sewn only partially to the front body parts 12 and 13 arranged on the left and right and / or the covering part 17. With such a configuration, ventilation can be achieved through the unsewn part (gap), so sweating, stuffiness, and the discomfort caused by them can be suppressed. In addition, the presence of the unsewn part can reduce the influence of the adhering parts 44 and 45 being pulled by the fabrics of the front body parts 12 and 13 and the covering part 17 arranged on the left and right, so the adhesion to the groin increases, and the isolation effect is further improved to suppress discomfort.

[0058] As described above, the embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes that do not deviate from the gist of the present invention are included in the present invention.

[0059] For example, in the embodiment, the case where the crotch gusset 18 is provided has been described, but the present invention is not limited to this, and men's underwear without the crotch gusset 18 can also provide the present invention.

[0060] Also, in the embodiment, it has been described that the back body and the front body are stitched on the left and right side surfaces, but it is not limited to this, and other forms - for example, instead of the left and right, stitching around the crack at the back of the buttocks - can also be adopted.
