Mode for Carrying Out the Invention

[0019] Hereinafter, the underwear according to the embodiment of the present invention will be described. In the present embodiment, a women's underwear will be described as an example. Note that the present invention is not limited to women's underwear and is similarly applicable to men's underwear. FIG. 1 is a front view of the women's underwear 11 of the present invention, FIG. 2 is a rear view of the women's underwear 11 shown in FIG. 1, FIG. 3 is a front side view of the back surface of the women's underwear 11 shown in FIG. 1, FIG. 4 is a rear side view of the wrong side of the women's underwear 11 shown in FIG. 1, FIG. 5 is a view of the inside of the women's underwear 11 shown in FIG. 1 as seen from the body opening, and FIG. 6 is a cross-sectional view taken along the cross-section line A shown in FIG. 1.

[0020] As shown in FIGS. 1 to 4, the underwear body 21 of the women's underwear 11 has a body opening 23 at the upper edge, a right leg opening 25 at the lower right edge, and a left leg opening 27 at the lower left edge.

[0021] It should be noted that there seems to be an error in the original text where "図1~図4に示すように、女性用下着11の下着本体21は、上縁に胴口23が位置し、下縁右に右脚口25が位置し、下縁左に左脚口27が位置している。" is translated as "As shown in FIGS. 1 to 4, the underwear body 21 of the women's underwear 11 has a body opening 23 at the upper edge, a right leg opening 25 at the lower right edge, and a left leg opening 27 at the lower left edge. " with an extra "less than" in the translation of "図3は図1に示す女性用下着11の裏面の正面側図 ". Also, the "二十九" in the original seems to be a mislabeled ID which should be corrected during the translation process. The above translation is based on the corrected understanding of the text. As shown in Figures 1 to 5, an absorbent section 35 is provided on the inside of the underwear body 21, extending from the front of the underwear body 21 through the crotch area to the rear.

[0022] Figure 6 is a cross-sectional view along the cross-sectional line A (from the front to the back of the paper) shown in Figure 1. As shown in Figure 6, the water-absorbing section 35 includes, for example, a first water-absorbing member 61 and a linear member 65. The first absorbent member 61 is located on the inside of the underwear body 21. The first absorbent component 61 is thicker than the underwear body 21. A closed space 51 is formed between the underwear body 21 and the first water-absorbing member 61.

[0023] As shown in Figure 6, multiple linear members 65 are housed within the enclosed space 51. As shown in Figure 6, the women's underwear 11 has a multi-layer structure consisting of an underwear body 21, a layer (closed space 51) containing a plurality of linear members 65, and a first water-absorbing member 61. Here, a high water absorption effect is achieved by the multiple linear members 65 housed in the enclosed space 51.

[0024] One end of the linear member 65 is located at the first boundary portion 125 on the right leg opening 25 side between the underwear body 21 and the absorbent portion 35. The other end of the linear member 65 is located at the second boundary portion 127 on the left leg opening 27 side between the underwear body 21 and the absorbent portion 35. The linear member 65 is longer than the widthwise length of the first water-absorbing member 61 at one end of the linear member 65.

[0025] One end of each of the multiple linear members 65 is positioned at equal intervals along the first boundary 125, and the other end is positioned at equal intervals along the second boundary 127.

[0026] Of the enclosed space 51, the space at the position corresponding to the front part of the underwear body 21 is designated as the first space 111, the space at the position corresponding to the crotch part of the underwear body 21 is designated as the second space 113, and the space at the position corresponding to the rear part of the underwear body 21 is designated as the third space 115. Here, the number (density) of linear members 65 located in the first space 111 and the third space 115 is greater (higher) than the number (density) of linear members 65 located in the second space 113. The thickness of the linear member 65 is 1 to 4 mm in diameter.

[0027] In this embodiment, the underwear body 21 is a knit made of a first material such as polyester, nylon, acrylic, or rayon. Furthermore, the first water-absorbing member 61 and the linear member 65 are knitted from a second material, such as polyester, which has higher water absorption than the first material.

[0028] The women's underwear 11 is formed by seamlessly knitting together the underwear body 21, the enclosed space 51, the first absorbent member 61, and the linear member 65 that constitute it.

[0029] The manufacturing process for women's underwear 11 is described below. Figure 7 is a diagram illustrating the manufacturing process of the women's underwear 11 shown in Figure 1. As shown in Figure 7, the first material is supplied to the knitting machine to knit the upper part of the underwear body 21 (above the dotted line x in Figure 7), with the front and back parts knitting simultaneously.

[0030] Then, when knitting reaches the position indicated by the dotted line in Figure 7, the knitting process for the front section stops. The stopped section is then secured to prevent it from unraveling. Next, the knitting process for the rear section, located below the dotted line x in Figure 7, proceeds. At this time, the knitting machine is supplied with the first material that makes up the underwear body 21, as well as the second material, and the first absorbent member 61 and the linear member 65 are knitted together with the lower rear section of the underwear body 21.

[0031] The knitting machine continues the knitting process even after completing the knitting of the rear section, knitting the crotch and front sections of the underwear body 21. This forms the crotch and front sections of the underwear body 21, the closed space 51, the first water-absorbing member 61, and the linear member 65. Finally, the end of the front section is moved upwards (folded back) and woven into the fastening section 131 shown in Figure 7 to secure it. This completes the production of the women's underwear 11 shown in Figure 1.

[0032] As explained above, in the women's underwear 11, the area corresponding to the delicate zone where menstrual blood flows has a multi-layer structure, as shown in Figure 6, consisting of the underwear body 21, a layer (closed space 51) containing multiple linear members 65, and a first absorbent member 61. Furthermore, the linear members 65 and the first absorbent member 61 are made of a second material with high water absorption. Therefore, leakage of menstrual blood can be effectively suppressed. In particular, the enclosed space 51 contains multiple linear members 65, which have a high water absorption effect.

[0033] Furthermore, according to the women's underwear 11, the underwear body 21, the first absorbent member 61, and the linear member 65 are knitted in a single step, resulting in a seamless construction that is highly durable and simplifies the manufacturing process.

[0034] Furthermore, according to women's underwear 11, it not only prevents menstrual blood leakage but also has the effect of preventing urinary incontinence.

[0035] Furthermore, according to the manufacturing method for women's underwear 11 described above, women's underwear 11 can be manufactured efficiently in a short amount of time. This makes it possible to reduce the price.

[0036] The present invention is not limited to the embodiments described above. In other words, those skilled in the art may make various modifications, combinations, subcombinations, and substitutions with respect to the components of the embodiments described above, within the technical scope of the present invention or its equivalents.

[0037] For example, although the above embodiment illustrates a seamless design, at least one or part of the underwear body 21, the first absorbent member 61, and the linear member 65 can be knitted separately and then sewn together. They may be combined. Furthermore, all or part of the materials that make up the women's underwear 11 may be made of antibacterial materials.

[0038] Furthermore, the first water-absorbing member 61 and the linear member 65 may be formed from a different material that has higher water absorption than the underwear body 21.

[0039] Furthermore, in the embodiments described above, women's underwear 11 was exemplified as the underwear of the present invention, but men's underwear may also be used. [Industrial applicability]
