Description

The present invention relates to women's bottom underwear.

In women's bottom underwear, various techniques have been proposed to prevent the hem portion from slipping up and the buttocks from protruding. For example, in Patent Document 1, the front center cloth hanging from the waist cloth to the crotch and the hip support cloth inclined to the left and right sides are connected in a Y shape, and the hip support cloth has a core along the gluteal sulcus. By attaching the material, the hip support cloth expands and contracts and follows the movement of the gluteal sulcus during behavior, and the core material also moves with the skin of the gluteal sulcus to prevent the buttocks from sticking out and stepping due to biting. The technology is described. Further, in Patent Document 2, a compensating region that can be expanded and contracted along the gluteal sulcus in a direction along the gluteal sulcus and in a direction substantially perpendicular to the gluteal sulcus is arranged and connected to the main body region and the hem region. , A technique is described in which the correction region can be made to follow a portion of the skin having a large expansion / contraction ratio, and the main body region and the hem region are interlocked with the correction region to effectively prevent the hem from slipping up. ..

Some conventional women's bottom underwear has been devised to prevent the buttocks from sticking out, but the fit to the wearer's crotch is not taken into consideration. Specifically, the crotch cloth may not fit in the crotch part due to a gap between the crotch part of the wearer and the crotch cloth of the bottom underwear for women. In such cases, the wearer tends to pull up the bottom underwear in an attempt to fit the crotch cloth to the crotch, resulting in the entire bottom underwear sliding up and the hem biting into the buttocks, causing discomfort. The present inventor paid attention to.

Therefore, it is a main object of the present invention to provide bottom underwear for women that has a fit to the crotch and is comfortable to wear.

As a result of diligent studies, the present inventor has found that the fit to the crotch portion of the crotch cloth is improved by forming the rear end portion of the crotch cloth into a specific wavy shape, and completes the present invention. It came to.

That is, the present invention

The women's bottom underwear may have a curved shape in which the outer shape of the crotch cloth is recessed inward when the bottom underwear for women is placed on a flat surface with the front side facing up.

According to the present invention, it is possible to provide a bottom underwear for women that has a fit to the crotch and is comfortable to wear.

It is a top view when the bottom underwear 1 for women is placed on a plane with the front side (ventral side) facing up. It is a top view of the crotch cloth 20. It is a rear view which shows the wearing state of the bottom underwear 1 for women.

Hereinafter, embodiments for carrying out the present invention will be described. In addition, the embodiment described below shows an example of the embodiment of the present invention, and the scope of the present invention is not narrowly interpreted by this.

First, the overall configuration of the women's bottom underwear of the present embodiment will be described. FIG. 1 is a plan view when the bottom underwear for women 1 is placed on a flat surface with the front side (ventral side) facing up.

As shown in FIG. 1, the women's bottom underwear 1 includes a main body cloth 10 and a crotch cloth 20. The configuration of the main body cloth 10 is not particularly limited, and may be composed of one cloth member or a plurality of cloth members. The main body cloth 10 shown in FIG. 1 includes a front main body cloth 11 located on the front side (ventral side) of the wearer and a rear main body cloth 12 located on the rear side (dorsal side) of the wearer.

The crotch cloth 20 is located at the wearer's crotch. The front end 21 of the crotch cloth 20 is joined to the crotch end 111 of the front body cloth 11. The rear end 22 of the crotch cloth 20 is joined to the crotch end 121 of the rear body cloth 12. The rear end portion 22 of the crotch cloth 20 has a specific wavy shape, and this wavy shape contributes to improving the fit of the crotch cloth 20 when worn. The details of the wave shape will be described later.

The rear end portion 22 of the crotch cloth 20 has a specific wavy shape, but the shape of the crotch side end portion 121 of the rear side main body cloth 12 joined to the rear side end portion 22 is not particularly limited. The shape of the crotch side end portion 121 of the rear body cloth 12 may be, for example, a linear shape, a curved shape, a wavy shape, or the like. From the viewpoint of improving the fit of the crotch cloth 20, it is preferable that the shape of the crotch side end portion 121 of the rear body cloth 12 is a curved shape bulging toward the rear (dorsal side) of the wearer.

As shown in FIG. 1, when the bottom underwear 1 for women is placed on a flat surface with the front side facing up, it is preferable that the outer shape 23 of the crotch cloth 20 has a curved shape recessed inward. As a result, when the women's bottom underwear 1 is worn, the crotch cloth 20 has a curved shape toward the crotch portion, and a gap is less likely to be formed between the crotch cloth 20 and the crotch portion. As a result, the fit of the crotch cloth 20 to the crotch portion is improved, and a better wearing comfort can be obtained.

The material of the main body cloth 10 and the crotch cloth 20 is not particularly limited, and materials generally used for women's bottom underwear can be used.

Next, the shape of the crotch cloth 20 will be described. FIG. 2 is a plan view of the crotch cloth 20. In FIG. 2, the seam allowance of the crotch cloth 20 is not shown.

In FIG. 2, the upward direction corresponds to the rear side (dorsal side direction) of the wearer, and the downward direction corresponds to the front side (ventral side direction) of the wearer. As shown in FIG. 2, the rear end portion 22 of the crotch cloth 20 has a first convex curve 22a bulging backward, a concave curve 22b recessed forward, and a second convex curve bulging backward. 22c and 22c form a wave shape in which they are arranged in this order. Here, the wave shape is a shape in which a convex curve and a concave curve appear continuously. Those whose convex or concave vertices form a straight line or an angle are not included in the convex curve and the concave curve.

When the corrugated rear end 22 is joined to the crotch end 121 (see FIG. 1) of the rear main body cloth 12, the corrugated rear end 22 and its peripheral portion become the wearer's crotch. It has a three-dimensional shape that follows the part.

Next, the preferred form of the wave shape will be described with reference to FIG.

Let L be a virtual line passing through a point P which is one end of the rear end portion 22 of the crotch cloth 20 and a point Q which is the other end, that is, a virtual line passing through both ends of the rear end portion 22 of the crotch cloth 20. The maximum distance between the virtual line L and the first convex curve 22a is α1, the maximum distance between the virtual line L and the concave curve 22b is β1, and the virtual line L and the second convex curve 22c. When the maximum distance to and from is γ1, β1 is not particularly limited, but is preferably longer than α1 and γ1.

Further, when the width of the first convex curve 22a is α2, the width of the concave curve 22b is β2, and the width of the second convex curve 22c is γ2, β2 is not particularly limited, but is larger than α2 and γ2. Long is preferred.

In FIG. 2, when the intersection of the rear end portion 22 of the crotch cloth 20 and the virtual line L is set to a point P, a point P1, a point Q1, and a point Q in order from one end of the rear end portion 22, the width is the same. α2 is the length of the virtual line L between the points P and P1, the width β2 is the length of the virtual line L between the points P1 and Q1, and γ2 is the lengths of the points Q1 and Q1. Is the length of the virtual line L between and.

FIG. 3 is a rear view showing a wearing state of the women's bottom underwear 1. Next, with reference to FIG. 3, the positional relationship between the crotch portion and the crotch cloth 20 when the women's bottom underwear 1 is worn will be described.

In FIG. 3, the broken line indicates the buttocks of the wearer W. As shown in FIG. 3, the rear end portion 22 of the crotch cloth 20 is along the skin of the crotch portion of the wearer W when worn. Therefore, a gap is less likely to occur between the crotch cloth 20 and the crotch portion, and the fit of the crotch cloth 20 to the crotch portion is improved.

Further, as described above, the outer shape of the crotch cloth 20 has a curved shape that is recessed inward (see FIG. 1), so that the crotch cloth 20 curves toward the crotch portion and becomes the crotch portion of the wearer W in FIG. The fit with the crotch cloth 20 becomes better.

Women's bottom underwear, which has a curved shape with the outer shape of the crotch cloth recessed inward, has existed for some time, but there was room for improvement in the fit to the crotch. As a result of diligent studies, the present inventor has made the rear end of the crotch cloth a specific wavy shape so that the rear end can be aligned with the skin of the crotch when worn. I found that. As a result, the gap between the crotch cloth and the crotch is reduced, and it is possible to improve the fit of the women's bottom underwear.
