Description

[Technical Field]

[0001] The present invention relates to underwear, and more particularly to underwear worn under a brassiere. [Background technology]

[0002] Bras, a type of underwear for women, are worn around the chest to protect the bust and correct the figure. Conventional bras, despite being in direct contact with the skin, have not been designed with sufficient consideration given to moisture absorption, which means that sweat accumulates in the cleavage and under the bust during hot summer months, causing stains on outerwear and causing itching and odors. Summary of the Invention [Problem to be solved by the invention]

[0003] The present invention has been developed in consideration of the above-mentioned conventional problems, and its purpose is to provide underwear that prevents sweat from accumulating in the cleavage or under the bust when wearing a brassiere. [Means for solving the problem]

[0004] The invention described in claim 1 is A cylindrical undergarment consisting of a cylindrical body with a neckline and left and right armholes, worn between the brassiere and the skin of the chest, The body is made of a stretchy and water-absorbent or moisture-wicking fabric, and has a length from the shoulders to the underside of the bust. The armholes are made wider on the back side of the body, with the body divided into front and back. It is characterized by: The invention described in claim 2 is The armhole is roughly oval or egg-shaped, with the long axis tilted forward. It is characterized by: The invention described in claim 3 is The long axis is tilted forward 30 to 40 degrees from the vertical axis. It is characterized by: The invention described in claim 4 is The neckline is formed so that the lower edge of the front is at the same height as the upper end of the armhole. It is characterized by: The invention described in claim 5 is Anti-stretch tape sewn along the edge of the neckline; It is characterized by: [Effects of the Invention]

[0005] According to this invention, when the wearer wears the underwear between the bra and the skin of the chest during hot weather, such as summer, the body is stretchy, so the front body stretches as it is lifted forward by the bust, but the area of ​​the left and right armholes is larger on the back side of the body, and the fabric area of ​​the front body is larger, so the stretch rate around the bust is small and the underwear fits well to the skin of the chest. Therefore, even if sweat occurs in the cleavage or under the bust, it is immediately absorbed by the underwear, so there is no unpleasant stickiness. In addition, the armholes are roughly oval or egg-shaped, elongated from top to bottom, and the long axis is tilted forward, which increases the fabric area around the sides of the bust and improves the fit of the body around the bust. In addition, the neckline is formed so that the lower edge on the front is at approximately the same height as the upper end of the armholes, which increases the fabric area above the bust, thereby improving the fit of the body around the bust and ensuring that sweat in the cleavage is absorbed. In addition, by sewing anti-stretch tape along the edge of the neckline, stretching of the neckline when worn can be suppressed, improving the fit between the left and right shoulder straps and the wearer's shoulders.

DETAILED DESCRIPTION OF THE INVENTION

[0007] Preferred embodiments of the present invention will be described below using examples. [Example]

[0008] An embodiment of underwear according to the present invention will be described with reference to Figures 1 to 6. Figure 1 is a perspective view of underwear according to one embodiment of the present invention, Figure 2 is a front view of the underwear of Figure 1 folded flat so that the front and back bodies overlap each other, Figure 3 is a back view of Figure 2, Figure 4 is a right side view of the underwear of Figure 1 folded flat so that the left and right halves overlap each other, Figure 5 is an explanatory diagram of the shape of the underwear of Figure 1, and Figure 6 is an explanatory diagram showing the underwear in use. In these figures, reference numeral 1 denotes a tubular undergarment worn between the brassiere and the skin of the chest, and is composed of a tubular body 5 with a neckline 2 and left and right armholes 3 and 4. The body 5 is made of a seamless, tubular knit fabric made from stretchy, water-absorbent, and moisture-wicking fibers such as cotton, linen, silk, wool, rayon, and cupra. The body 5 has a length from the shoulders to the underside of the bust (to the waist in this embodiment). The circumference of the body 5, where the length is H, is preferably 1.60H to 1.80H.

[0009] The neckline 2 has a smooth and rounded round-neck shape. Inside the body 5 is divided into the front body 6 and the back body 7, the depth d1 on the front body 6 side is shallower than the depth d2 on the back body 7 side, and the lower end edge of the front side of the neckline 2 is formed to be approximately the same height as the upper ends of the armholes 3 and 4. As a result, a wide raw area is secured under the neckline 2 on the front body 6 side. Taking the length of the body 5 as H, preferably, it is in the range of 0.15H ≤ d1 ≤ 0.25H, 0.22H ≤ d2 ≤ 0.32H (however, d1 < d2).

[0010] The left and right armholes 3 and 4 are approximately elliptical and long in the vertical direction. Inside the area is divided into the front body 6 and the back body 7, the area on the back body 7 side is formed to be wide, and a wide raw area is secured on the front body 6 side. That is, as shown in Fig. 5, the center C of the left and right armholes 3 and 4 is inside the back body 7. Also, the long axis L of the left and right armholes 3 and 4 is inclined with respect to the vertical axis, and the inclination angle θ is preferably in the range of 30 degrees to 40 degrees. Preferably, the major diameter L1 of the left and right armholes 3 and 4 is 0.30H to 0.36H, and the minor diameter L2 is 0.17H to 0.23H.

[0011] When the wearer wears the undergarment 1 formed as described above between the bra 20 and the chest skin during hot seasons such as summer as shown in Fig. 6. Then, since the body 5 has elasticity, the front body 6 extends while being lifted forward by the bust, but the area of the left and right armholes 3 and 4, inside the body 5 is divided into the front body 6 and the back body 7, the area on the back body 7 side becomes wider, and thus the raw area of the front body 6 becomes wider. Therefore, the elongation rate around the bust can be small, and the adhesion to the chest skin is good. Consequently, even if sweat occurs in the valley between the breasts or under the bust, it is immediately absorbed by the undergarment 1, so an unpleasant sticky feeling does not occur. Also, the armholes 3 and 4 are approximately elliptical and long in the vertical direction, and the long axis L is tilted forward, so the raw area near the sides of the bust becomes wider, and the adhesion of the body 5 around the bust becomes even better. Furthermore, the neckline 2 is formed so that the lower edge on the front side is at approximately the same height as the upper ends of the armholes 3 and 4, which increases the fabric area above the bust, thereby improving the fit of the body 5 around the bust and ensuring that sweat in the cleavage can be absorbed.

[0012] In the above embodiment, the armholes are generally oval in shape, but as shown by reference numeral 40 in Fig. 7, they may be generally egg-shaped and long from top to bottom, with the radius of curvature Ra of the arc at the upper edge 40a being smaller than the radius of curvature Rb of the arc at the lower edge 40b, and the major axis L' tilting forward by approximately 30 to 40 degrees. By making the upper part of the armhole 40 smaller, a larger area of ​​fabric can be secured at the sides of the bust compared to a generally oval shape. Furthermore, as shown in Figure 8, anti-stretch tape 8 may be sewn along the edge of the neckline 2, thereby preventing the neckline from stretching when worn and improving the fit between the left and right shoulder straps 9, 10 and the wearer's shoulders. [Industrial Applicability]

[0013] The present invention can be applied to underwear worn between a brassiere and the skin. [Explanation of symbols]
