DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The shorts according to the present invention will be described below in detail with reference to the accompanying drawings.

FIGS. 1, 2 and 3 are front views of shorts 1 suitable for wearing together with a urine absorbing pad or a sanitary napkin.
It is a rear view and a partially broken side view. The shorts 1 have a front body piece 2, a back body piece 3, and a crotch piece 4, and the front and rear body pieces 2, 3 overlap and are sewn together at a line 6 extending in the vertical direction on the ventral side of the shorts 1. . Inseam piece 4
Is an outer sheet 4a that forms the outer surface of the shorts 1 and extends in the front-rear direction at the crotch;
And an inner sheet 4b covering a part of the back body piece 3 from the inside of the outer sheet 4a.
Lines 5 and 7 are sewn to the front and rear body pieces 2 and 3, and these lines 5 and 7 extend in a lateral direction intersecting the front-rear direction. The inner sheet 4b is longer than the outer sheet 4a, and is sewn to the front body piece 2 with a line 5 and to the rear body piece 3 with a line 8 located behind the line 7.

The shorts 1 have a torso opening 11 and a pair of leg openings 12, and a decorative tape 13 having elasticity and elasticity in a waist direction is formed around a line 13 a at the periphery of the torso opening 11.
Along the front and rear body pieces 2 and 3 respectively.
The peripheral edge of the leg opening 12 is formed by a back body piece 3, a crotch piece 4, and a leg circumference piece 14 that is stitched to the back body piece 3, the crotch piece 4, and the front body piece 2 and extends long in the leg circumferential direction. Is formed. The leg surrounding piece 14 and the front body piece 2 are stitched along a line 14a. A decorative tape 15 having elasticity and elasticity in the leg-circumferential direction is sewn along a line 15a to a portion of the peripheral edge of the leg opening 12 other than the leg-circumferential pieces 14.

An elastic stretch tape 16 extending in the longitudinal direction is sewn to the inner surface of the central portion in the lateral direction of the back body piece 3.
The tape 16 extends from the upper edge of the back body piece 3 to the suture line 8 by longitudinally cutting the back body piece 3. In the illustrated example, the tape 16 is sewn to the back piece 3 in a stretched state at a portion 18 near the line 8, and the tape 20 contracts to form a gather 20 at the portion 18. The tape 16 is sewn to other parts of the back body piece 3 in a substantially non-extended state. In order to make the rear part of the urine absorbing pad or the sanitary napkin adhere to the skin, the tape 16 is preferably in such an extended state,
It is also possible to implement the present invention by attaching the entire tape 16 to the shorts 1 in a non-extended state.

Each body piece 2, 3, 4 forming shorts 1
Among them, the front and rear body pieces 2 and 3 have elasticity in the vertical direction of the shorts 1 and the horizontal direction orthogonal to this direction. However, the front body piece 2 has a greater extension force in the vertical direction than that in the horizontal direction, in other words, it is easier to extend in the horizontal direction than in the vertical direction. The back body piece 3 has a smaller extension force in the vertical direction than that in the horizontal direction, and is easier to extend in the vertical direction than in the horizontal direction. In addition, the extension force of the tape 16 in the longitudinal direction of the back body piece 3 is small. The crotch piece 4 in a state where the outer sheet 4a and the inner sheet 4b overlap each other has elasticity in the front-rear direction and the lateral direction, and the extension force in the front-rear direction is greater than that in the lateral direction. It is larger than the longitudinal extension force of the body pieces 2 and 3. In other words, it is easy to extend in the horizontal direction and hard to extend in the vertical direction. The leg-surrounding piece 14 has elasticity in the leg-surrounding direction and in a direction perpendicular to the leg-surrounding direction. . The lateral extension force of the decorative tape 13 extending along the trunk opening 11 may or may not exceed the lateral extension force of the front and rear body pieces 2 and 3.

In the present invention, the extension force of each body piece 2, 3, 4 is measured as follows.

(1) Dimensions of Specimens A specimen having a width of 2.5 cm and a length of 15 cm in each direction in which the elongation force is to be obtained is prepared. As for the inseam piece, a test piece is prepared in a state where the outer sheet and the inner sheet are overlapped. (2) Chuck interval of tensile tester 10 cm (3) Tensile speed 10 cm / min (4) First tensile test specimen is stretched to 180%, and then contracted by releasing the stretching force. (5) Second Tensile The specimen is elongated to 130%. The stretching force at this time is obtained, and the value is used to compare the ease of stretching of each body in each direction.

In a preferred example of the shorts 1 according to the present invention, the extension force measured in this way is 0.754 N and 0.401 in the longitudinal direction and the lateral direction of the front body piece 2.
N, 0.18 in the vertical and horizontal directions of the back body piece 3
0N and 0.563N, the longitudinal extension force of the front body piece 2 is larger than that of the back body piece 3, and the lateral extension force of the front body piece 2 is smaller than that of the back body piece 3. . The longitudinal extension force of the crotch piece 4 is preferably greater than that of the front body piece 2.

The shorts 1 thus formed have a front body piece 2 and a tape 1 which have a large vertical extension when worn with, for example, a urine absorbing pad placed inside the crotch.
6 lifts the pad and makes it adhere to the crotch of the wearer of the shorts 1. Also, the front body piece 2 is easy to stretch in the lateral direction,
The shorts 1 abut on the abdomen of the wearer without compressing the abdomen. Since the back body piece 3 has a large extension force in the lateral direction and further extends to the abdomen covering the waist circumference of the wearer of the shorts 1 (see FIG. 1), it strongly adheres to the waist of the wearer. Such shorts 1 do not easily shift even if the wearer's body moves violently, and the adhesion of the urine absorbing pad to the crotch is maintained in a good state. By providing the leg surrounding cloth piece 14 that is easy to expand and contract and is wide at the periphery of the leg opening 12, it is possible to eliminate the problem that the wearer's shorts 1 hinders the movement of the leg of the wearer. The crotch piece 4 has a large extension force in the front-rear direction, and acts in cooperation with the front body piece 2 and the tape 16 to strongly adhere the urine absorbing pad to the crotch. Such shorts 1 can be used for sanitary napkins in addition to being used for urine absorption pads.

[0018]

In the shorts according to the present invention, the front body piece having a large longitudinal extension force and the elastic elastic tape attached to the rear body piece cooperate to wear the urine absorbing pad or the sanitary napkin. The body fluid can be prevented from leaking by closely contacting the crotch of the person. Further, the front body piece has a small stretching force in the lateral direction of the shorts and abuts against the abdomen of the wearer of the shorts without pressing the abdomen, while the body piece of the back body has a large stretching force in the lateral direction and the wearer wears the shorts. Can firmly adhere to the waist.
