ABSTRACT:
TECHNICAL FIELD
The present invention relates to a garment with a crotch part having a structure for holding an absorbent article, such as a sanitary napkin or an incontinence pad, on the crotch part with stability and security.
BACKGROUND ART
Absorbent articles such as a sanitary napkin or an incontinence pad are used widely as sanitary goods for absorbing a body fluid such as menstrual blood or urine. Taking a sanitary napkin as a representative example to be described, various improvements have been added so that it can be mounted to a garment with a crotch part, such as a short panty, on the crotch part with stability and ease. Recently, as illustrated in
FIG. 26
, a sanitary napkin in which foldable pieces
202
(hereinafter may be referred to as wings) are provided on the right and left sides of a napkin body
201
and these foldable pieces
202
have adhesive portions
203
covered with separable protection films (not illustrated) is common.
In such a conventional napkin, as illustrated in
FIG. 27
, the napkin body
201
is applied onto the inner side of a crotch part
206
of a short panty main body
205
. While the wings
202
are folded onto the outer side of the short panty main body
205
, the separable protection films are removed from the adhesive portions
203
, and the wings
202
are adhered to the outer side of the crotch part
206
with the adhesive portions
203
.
Thus, the napkin is held on the crotch part
206
of the short panty main body
205
with stability and security.
However, in a sanitary garment with a crotch part such as the above-described conventional sanitary short panty, because the wings
202
of the napkin are exposed on the outer side of the short panty main body
205
, it has poor appearance.
Although a sanitary napkin is described herein as a representative example, an incontinence pad or other absorbent article for absorbing urine or other discharged body fluid, other than menstrual blood, which has wings just as the napkin shown in
FIG. 26
, also may be assumed. With respect to the case of using such an assumed absorbent article with wings, the same matters are considered. In the following, a case of using a sanitary napkin is described as a representative example.
To solve these problems, for example, a sanitary short panty as described in Japanese Utility Model Registration No. 3002607 has been proposed.
In this sanitary short panty, as shown in the perspective view for its main parts in
FIG. 28
, a waterproof cloth
213
is placed on the inner side of a crotch part
212
of a short panty main body
211
. Front and rear ends
214
and
215
of the waterproof cloth
213
, and portions
216
and
217
of the right and left sides of the waterproof cloth
213
near the front and rear ends are sewn to the short panty main body
211
. The right and left edges
218
of the waterproof cloth
213
are not sewn to the short panty main body
211
and are in free state. That is, the wings
202
of the napkin are folded into the gap between the waterproof cloth
213
and the crotch part
212
, where the waterproof cloth
213
is not sewn to the short panty main body. These folded wings
202
are adhered to the back side of the waterproof cloth
213
.
Thus, in a conventional sanitary short panty, by folding the wings
202
of the napkin onto the back side of the waterproof cloth
213
, the wings
202
are prevented from being exposed on the outside of the short panty main body.
However, such a conventional sanitary short panty does not have a structure to make the mounting of a napkin with wings easy. The gap between the crotch part
212
of the short panty main body
211
and the waterproof cloth
213
is small, and folding of the wings to mount the napkin is difficult. Furthermore, because the adhesive portions
203
of the wings
202
are adhered directly to the back side of the waterproof cloth
213
, when changing the napkin or washing the short panty, the napkin is peeled away from the short panty. When peeling the wings
202
of the napkin frequently, the waterproof resin coating on the waterproof cloth
213
also is peeled by the adhesive strength of the adhesive portions. This causes reduced waterproof property and leaking. Furthermore, close contact of a napkin mounted on the waterproof cloth with respect to the crotch region of the body of the wearer is not considered much in a conventional sanitary short panty.
To dissolve these problems, for example, a sanitary short panty as described in Japanese Utility Model Registration No. 3047126 has been proposed.
FIG. 29
is a plan view of a crotch part and its vicinity of the above-mentioned short panty, viewed from the inside of the short panty.
FIG. 30
is an approximate sectional view taken along the line A-A′ of FIG.
29
.
FIG. 31
is a detailed sectional view of only a cloth piece
225
for holding a sanitary napkin (second crotch cloth piece) of
FIGS. 29 and 30
. The crotch part of the sanitary short panty shown in
FIGS. 29
to
31
has the following structure.
The sanitary short panty includes a short panty main body, which is comprised of a front body fabric
222
, a rear body fabric
223
, and a crotch cloth piece
224
for joining the lower end of the front body fabric
222
and the lower end of the rear body fabric
223
. A cloth piece
225
(a second crotch cloth piece) for holding a napkin (see
FIG. 26
) applied is mounted on the crotch cloth piece
224
, and a stretch tape
226
having a smaller width and a slightly shorter length than the second crotch cloth piece
225
and the crotch cloth piece
224
is mounted between the second crotch cloth piece
225
and the crotch cloth piece
224
at the center in the width direction. As illustrated in
FIG. 31
, the second crotch cloth piece
225
has a three-layer structure consisting of a stretchable net cloth
225
e
to be in direct contact with the skin, a waterproof cloth
225
f
, and a stretchable net cloth
225
g
on which the right and left wings
202
of a napkin are to be applied. The entire shape of the second crotch cloth piece
225
is approximately the same as that of the crotch cloth piece
224
. The stretchable net cloth
225
e
to be in direct contact with the skin and the waterproof cloth
225
f
are integrated by adhesion (lamination) in overall. The net cloth
225
e
and waterproof cloth
225
f
are integrated with the net cloth
225
g
by sewing them at the whole peripheries thereof.
Thus, by mounting the stretchable net cloth
225
g
as a backing cloth for the waterproof cloth
225
f
, direct adhesion of the adhesive portions
203
in the right and left wings
202
of the napkin to the waterproof cloth
205
f
is prevented. According to this structure, when peeling the right and left wings
202
of the napkin frequently, the waterproof resin coating on the waterproof cloth
225
f
is not peeled by the adhesive strength of the adhesive portions
203
, so that reduced waterproof property and leaking are not caused.
Furthermore, the rear edge
226
b
of the stretch tape
226
is sewn to the lower end of the rear body fabric
223
together with the rear edge
224
b
of the crotch cloth piece
224
. Right and left edges
225
c
and
225
d
of the second crotch cloth piece
225
are open edges not sewn to the crotch cloth piece
224
. Right and left edges
226
c
and
226
d
of the stretch tape
226
also are open edges not sewn to the crotch cloth piece
224
. That is, both the second crotch cloth piece
225
and the stretch tape
226
are mounted to the short panty main body only at the front and rear edges
225
a
and
225
b
or the front and rear edges
226
a
and
226
b.
However, in both the sanitary short panty illustrated in FIG.
28
and the sanitary short panty illustrated in
FIGS. 29
to
31
, it is necessary that a waterproof cloth treated with a liquid-impermeable coating such as resin, like the waterproof cloth
213
or the waterproof cloth
225
f
, is used in the crotch part thereof. However, when using a waterproof cloth, it is easy to be steamed and itching or the like is easy to occur
