DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the shorts according to the present invention will be described in detail with reference to the drawings. Figure 1,
2 and 3 are a front view, a rear view, and a partially cutaway side view of the shorts of the present invention, respectively.

[0007] The shorts 1 include a suture line 4 extending in the vertical direction on the ventral side of the shorts 1 by connecting the front view piece 2 and the back body piece 3 to each other.
And a shorts main body 1a having a waist opening 11 and a pair of leg openings 12 formed therein. Further, the back body piece 3 is folded back at the center folding line 7 and also serves as the crotch part 6, and is sewn to the front body piece 2 at the suture line 5. Further, the front body piece 2 may be folded back at the center folding line 7 so as to also serve as the crotch portion 6, and may be stitched to the rear body piece 3 at the suture line 8. A crotch pad 6b is in contact with the inside of the crotch part 6. The crotch pad 6b is sewn to the front piece 2 at the front side of the shorts 1 at the suture line 5 and sewn to the back body piece 3 at the rear side of the shorts 1 at the suture line 8. These suture lines 5, 8 extend laterally as shown in FIGS.

In another embodiment of the shorts body 1a,
The shorts 1 are a front look piece 2, a back body piece 3, and a crotch piece 6a.
(See FIG. 3). The front-looking piece 2 and the back body piece 3 are sewn on a suture line 4 extending in the vertical direction on the ventral side of the shorts 1. The crotch piece 6a forms the crotch 6 together with the crotch pad 6b abutted on the inside. The crotch piece 6a and the crotch pad 6b are sewn to the front body piece 2 at the suturing line 5, and are sewn to the back body piece 3 at the suturing line 8. These suture lines 5, 8 are shown in FIGS.
As shown in FIG.

In these shorts 1, the lateral dimension of the rear-viewable piece 3 is formed larger than the lateral dimension of the front-piece piece 2, and the front-body piece 2 is shifted more abdominally than the waist side of the shorts 1. It is sewn in the position where it did. That is, the front piece 2
The suture line 4 between the back body piece 3 and the back body piece 3 is located on the ventral side of the shorts 1 wearer. Further, although not shown, the back body piece 3 may be divided into right and left at a center line in the width direction and integrated by suturing. In these shorts 1,
An absorptive pad (not shown) can be attached inside the crotch part 6, that is, inside the crotch pad 6b.

The front body piece 2 and the back body piece 3 are preferably made of a two-way stretch cloth having elasticity in the vertical and horizontal directions. As the crotch piece 6a, a cloth having elasticity in the front-rear direction and the lateral direction is used, but it is more preferable that the extension force in the front-rear direction is larger than the extension force in the lateral direction, that is, it is more difficult to extend in the front-rear direction.

A waterproof breathable or synthetic resin sheet cloth is used for the crotch pad 6b, but is preferably non-stretchable. This makes it difficult for the crotch part 6 to extend in the vertical and horizontal directions, so that when the absorbent pad is attached, the adhesive tape on the back sheet of the absorbent pad does not easily come off.

At the peripheral edge of the waist opening 11, a decorative tape 13 having elasticity in the waist direction is provided with a sewn line 13a.
Are sewn along the pieces 2 and 3 in front and rear.

In the shorts 1 shown in the drawing, a leg piece 14 separate from the front body piece 2 is provided at a front part of the leg opening 12.
Are sewn along the suturing line 14a, and the pair of leg openings 12 is formed by the leg piece 14, the crotch 6, and the back body piece 3. A decorative tape 15 having elasticity in the leg-circumferential direction is sewn to the periphery of the leg-surrounding opening 12 except for the portion where the leg-circumfering pieces 14 are arranged, along a sewing line 15a.

The leg-surrounding piece 14 has elasticity in the leg-circumferential direction and in a direction perpendicular to the leg-circumferential direction, but the extension force in the leg-circumferential direction is smaller than the extension force in the direction perpendicular to this direction. It is more preferable to use a cloth that easily stretches.

An elastic tape 16 extending in the vertical direction is attached to the inner surface side of the rear body piece 3 at a substantially central position in the width direction. In the present invention, the elastic tape 16 extends from the waist opening 11 side of the back body piece 2 to the front of the crotch portion 6 beyond the center return line 7 of the shorts body 1a, The position 17 is characterized by being 25 to 75 mm above the center folding line 7. As the elastic tape 16, a bias tape having a width of 3 to 20 mm, preferably woven with urethane fiber, is used.

The position 17 at which the distal end of the elastic tape 16 is attached
Is less than 25 mm from the center return line 7,
The elastic tape 16 can only reach the vaginal opening only,
The absorbent pad used together does not adhere to the urethral opening. Further, if the distal end attachment position 17 of the elastic tape 16 exceeds 75 mm, it separates from the genital area of the wearer, so that it is unnecessary to extend it beyond 75 mm for the close contact of the absorbent pad. The tip mounting position 17 is between the center folding line 7 and 35
More preferably up to 65 mm, 50 mm
Most preferably, it is above and below.

In the example shown in FIG. 2, the elastic tape 16 has a contracted elastic gather having a length of 30 to 110 mm in a fixed area 18 above the suture line 8 between the back body piece 3 and the crotch piece 6b. The part 20 is formed. The elastic gathering portion 20 can be formed by attaching the elastic tape 16 vertically below the certain region 18 above the suture line 8 while extending the other portions, while attaching the other portions to the non-stretched lower portion. The elongation rate when the elastic tape 16 is attached under elongation is preferably about 120%.

When the length of the elastic gathering portion 20 is less than 30 mm, the wearer cannot absorb the movement of the wearer, such as standing or sitting, and the wearer's movement tends to shift the absorbent pad. In addition, the length of the elastic gathering portion 20 is 110 m.
When the length exceeds m, the entire shorts 1 shrinks, and when the shorts 1 are worn, the waistline is pulled downward and becomes V-shaped. In order to make the rear part of the absorbent pad adhere to the skin, it is preferable to form the elastic gathering part 20. However, the present invention can be carried out by attaching the entire tape 16 to the shorts 1 without stretching. It is.

By arranging the elastic tape 16 as described above, the crotch 6 of the shorts 1 in contact with the urine absorbent pad or the absorbent pad such as a sanitary napkin is pulled by the elastic tape 16. The elastic force acts as a pressing force via an absorbent pad (not shown) in a region where the anus and the urethral opening and the vaginal opening face each other. As a result, the bodily fluids such as urine and menstrual blood can be effectively absorbed by the absorbent pad, and the bodily fluids such as urine and menstrual blood can be prevented from leaking from the absorbent pad.

The shorts 1 are formed by forming an elastic gathering portion 20 of 30 to 110 mm above the suture line 8.
Can follow the movement of the wearer, so that the absorbent pad does not deviate from the genital area of the wearer, and leakage of body fluid can be further prevented.

Further, by providing the elastic leg piece 14 at the front part of the leg opening 12, the movement of the leg of the wearer of the shorts 1 is not hindered, and the leg part of the wearer, especially the groin, is not hindered. No unnecessary pressure on the part.

Furthermore, the lateral dimension of the back body piece 3 is
The front body piece 2 is formed to be larger than the lateral dimension of the front body piece 2, and the front and rear view piece 2.3 is sewn at a position deviated more abdominally than the waist side of the shorts 1, so that the suture line 4 is formed by the wearer. When wearing shorts 1 without touching the hip bone,
It is possible to eliminate a sense of discomfort due to the suture line 4 coming into contact with the hip bone of the wearer.

Although the embodiment of the present invention has been described in detail above, the present invention is not limited to this.
Changes can be made without departing from the present invention.
