The following describes an embodiment of a pants-type wearing article with reference to the drawings.

(First embodiment)

Figure 1 shows a pants-type wearing article 1 of the first embodiment in an unfolded state. The pants-type wearing article 1 is intended to be men's pants. Figure 1 shows the inner surface of the pants-type wearing article 1 that faces the skin of the wearer.

Figure 2 is a front view of the pants-type wearing article 1.

Figure 3 is a rear view of the pants-type wearing article 1.

Figure 4 is a cross-sectional view taken along line A-A in Figure 1.

The pants-type wearing article 1 is composed of a pants body 40, antibacterial metal particles 42, a first activated carbon layer 1C, a first skin-side fabric 51, a second activated carbon layer 2C, and a second skin-side fabric 52.

The pants body 40 consists of a front body section 10, a back body section 20, and a crotch section 30. The front body section 10 forms the front side of the pants body 40. The back body section 20 forms the back side of the pants body 40.

The crotch section 30 constitutes the portion located between the front section 10 and the back section 20.

The pants body 40 is made up of a fabric body 41. The fabric body 41 is made from natural fibers such as cotton and linen, or synthetic fibers such as rayon, acetate, acrylic, polyester, and polyurethane.

The pants body 40 may be manufactured by sewing the front body 10, back body 20, and crotch body 30 together as separate pieces of fabric, or the pants body 40 may be manufactured by using any two of the front body 10, back body 20, and crotch body 30 as separate pieces of fabric, or the pants body 40 may be manufactured by using all of the front body 10, back body 20, and crotch body 30 as a single piece of fabric.

The antibacterial metal particles 42 can be, for example, silver ions (Ag+). The silver ions (Ag+) 42 are added throughout the fabric body 41. The silver ions (Ag+) 42 are attached to the fiber surface by, for example, impregnating the fibers of the fabric body 41.

When a fabric body 41 made of natural or synthetic fibers is immersed in a silver ion solution, nano-silver particles are attached to the surface of the fibers. Silver has metallic properties that allow it to maintain a zeta potential (surface charge of the particles) when in the form of nanoparticles. When positively charged silver nanoparticles are adsorbed onto the surface of silver ions (Ag+) and negatively charged odorous substances, the molecules of the odorous substances are oxidized and decomposed, killing them.

The silver ions (Ag+) 42 added throughout the fabric body 41 in this way prevent body odor and fart odor from inside the pants body 40 from being released to the outside.

In addition, silver ions (Ag+) 42 may be added to the fibers of the fabric body 41 by kneading them into the fibers during the spinning process.

In addition, it is also possible to use, for example, copper ions (Cu+) as the antibacterial metal particles 42.

A first activated carbon layer 1C is disposed in the first odor release suppression region 41A, which is a portion of the skin-facing area of the fabric body 41. The first activated carbon layer 1C is made of carbon fiber formed into a sheet.

The first odor release suppression region 41A, which is a portion of the skin-facing region 41A of the fabric body 41, consists of a first crotch region 31A of the crotch region 30, a first front region 11A of the front body portion 10 on the side of the first crotch region 31A, and a first back region 21A of the back body portion 20 on the side of the first crotch region 31A.

The first skin-side fabric 51 is joined to the fabric body 41, for example by sewing, with the first activated carbon layer 1C sandwiched between them. Any joining method, such as heat fusion, can be used. The same applies below.

The first activated carbon layer 1C adsorbs odorous substances using the micropores of the carbon fibers. As a result, the first activated carbon layer 1C prevents the odors of sweat, urine, and other excrement in the first odor emission suppression area 41A from being released to the outside.

A second activated carbon layer 2C is disposed in the fart odor emission suppression area 51A, which is a portion of the skin-side area of the first skin-side fabric 51. The second activated carbon layer 2C is configured to have a smaller area than the first activated carbon layer 1C. Like the first activated carbon layer 1C, the second activated carbon layer 2C is formed from carbon fiber in a sheet shape.

The fart odor emission suppression region 51A, which is a portion of the skin-facing region 51A of the first skin-facing fabric 51, consists of a portion of region 32A of the first crotch region 31A and a portion of region 22A of the first back region 21A.

The fart odor emission suppression area 51A is an area for suppressing the emission of fart odor generated from the anus to the outside.

The second skin side fabric 52 sandwiches the second activated carbon layer 2C and is joined to the first skin side fabric 51, for example by sewing.

The second activated carbon layer 2C adsorbs odorous substances using the micropores in the carbon fibers. As a result, the second activated carbon layer 2C prevents sweat, urine, and other excrement odors, particularly fart odors, from being released to the outside in the fart odor emission suppression area 51A.

(Effects of the pants-type wearing article 1 of the first embodiment)

(Prevents fart odor from being released externally)

When a wearer of the pants-type garment 1 inadvertently releases a fart from the anus, the fart odor is captured by the second activated carbon layer 2C in the fart odor emission suppression region 51A, which is the region that extends around the anus. Furthermore, because the first activated carbon layer 1C is provided in the thickness direction of the second activated carbon layer 2C, the fart odor traveling in the thickness direction that was not completely captured by the second activated carbon layer 2C is captured by the first activated carbon layer 1C. Furthermore, because the fabric main body 41 to which silver ions (Ag+) 42 have been added is provided in the thickness direction of the first activated carbon layer 1C, the fart odor traveling in the thickness direction that was not completely captured by the second activated carbon layer 2C and first activated carbon layer 1C is captured by the fabric main body 41.

In addition, because the first activated carbon layer 1C extends outward from the second activated carbon layer 2C in the fart odor emission suppression area 51A, the outward spreading fart odor that was not completely captured by the second activated carbon layer 2C is captured by the first activated carbon layer 1C. Furthermore, because the fabric main body 41 to which silver ions (Ag+) 42 have been added extends outward from the first odor emission suppression area 41A, the fabric main body 41 captures the outward spreading fart odor that was not completely captured by the second activated carbon layer 2C and first activated carbon layer 1C.

As a result, the first embodiment can prevent the release of fart odors to the outside, compared to conventional technology.

(Fabric and carbon fiber material reduction effect)

According to the first embodiment, the areas of the first skin-side fabric 51 (first odor emission suppression region 41A) and the first activated carbon layer 1C can be made smaller than the area of the fabric main body 41. Furthermore, the areas of the second skin-side fabric 52 (fart odor emission suppression region 51A) and the second activated carbon layer 2C can be made smaller than the first skin-side fabric 51 (first odor emission suppression region 41A) and the first activated carbon layer 1C. This allows for the effect of suppressing the external emission of fart odor to be achieved while minimizing the amount of fabric and carbon fiber material used and costs.

(Improves comfort and lower body appearance)

According to the first embodiment, when the wearer puts on the pants-type garment 1, the waist and side buttocks are only thickened by the main fabric body 41, without the additional thickness of the first skin-side fabric 51 and second skin-side fabric 52. This provides the effect of suppressing the release of flatulence odor to the outside, while also providing a comfortable fit, making the underwear lines around the waist and side buttocks less noticeable, and improving the appearance of the wearer's lower body.

(Second embodiment)

Figure 5 shows the unfolded state of the pants-type wearing article 2 of the second embodiment. The pants-type wearing article 2 is intended to be women's pants. Figure 5 shows the inner surface of the pants-type wearing article 2 that faces the wearer's skin.

Figure 6 is a front view of the pants-type wearing article 2.

Figure 7 is a rear view of the pants-type wearing article 2.

Figure 8 is a cross-sectional view taken along line A-A in Figure 5.

Hereinafter, components that overlap with those in the first embodiment will be assigned the same reference numerals and redundant explanations will be omitted where appropriate. Differences from the first embodiment will be described below.

The pants-type wearing article 2 is composed of a pants body 40, antibacterial metal particles 42, a first activated carbon layer 1C, a first skin-side fabric 51, a third activated carbon layer 3C, and a third skin-side fabric 53.

A third activated carbon layer 3C is disposed in the menstrual odor emission suppression region 51B, which is a portion of the skin-side region of the first skin-side fabric 51. The third activated carbon layer 3C is configured to have a smaller area than the first activated carbon layer 1C. Like the first activated carbon layer 1C, the third activated carbon layer 3C is formed from carbon fiber in a sheet shape.

The menstrual odor emission suppression region 51B, which is a portion of the skin-facing region 51B of the first skin-facing fabric 51, consists of a portion of region 32B of the first crotch region 31A and a portion of region 12A of the first front region 11A.

The menstrual odor emission suppression area 51B is an area that suppresses the release of menstrual odor generated from the vagina to the outside.

The third skin-side fabric 53 sandwiches the third activated carbon layer 3C and is joined to the first skin-side fabric 51, for example by sewing.

The third activated carbon layer 3C adsorbs odorous substances using the micropores of the carbon fiber. As a result, the third activated carbon layer 3C suppresses the release of sweat, urine, and other excrement odors, particularly menstrual odor, from the menstrual odor release suppression region 51B to the outside.

The pants-type wearing article 2 of the second embodiment can prevent menstrual odor from being released to the outside, as described in the first embodiment. It also achieves the same effect of reducing fabric and carbon fiber material. It also achieves the same effect of improving comfort and the appearance of the lower body.

(Third embodiment)

Figure 9 shows the unfolded state of a pants-type wearing article 3 of the third embodiment. The pants-type wearing article 3 is intended to be women's pants. Figure 9 shows the inner surface of the pants-type wearing article 3 that faces the wearer's skin.

Figure 10 is a front view of the pants-type wearing article 3.

Figure 11 is a rear view of the pants-type wearing article 3.

Figure 12 is a cross-sectional view taken along line A-A in Figure 9.

In the following, components that overlap with those in the first and second embodiments will be assigned the same reference numerals and duplicate explanations will be omitted where appropriate. Differences from the first and second embodiments will be described below.

The third embodiment is configured by combining the components of the first and second embodiments.

The pants-type wearing article 3 is composed of a pants body 40, antibacterial metal particles 42, a first activated carbon layer 1C, a first skin-side fabric 51, a second activated carbon layer 2C, a third activated carbon layer 3C, a second skin-side fabric 52, and a third skin-side fabric 53.

The second activated carbon layer 2C and the third activated carbon layer 3C may be integrated or separate. Alternatively, the second activated carbon layer 2C and the third activated carbon layer 3C may be separate and partially overlapped.

The second skin side fabric 52 and the third skin side fabric 53 may be integral or separate. Alternatively, the second skin side fabric 52 and the third skin side fabric 53 may be separate and partially overlapped.

The pants-type wearing article 3 of the third embodiment can prevent the release of flatulence odor and menstrual odor to the outside, as described in the first embodiment. It also achieves the same effect of reducing fabric and carbon fiber material. It also achieves the same effect of improving the wearing comfort and the appearance of the lower body.
