ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a trunks-type garment and more particularly to such a garment suitable as disposable garment.
BACKGROUND ART
In many cases, a transition between front and rear bodies in a crotch region of a trunks-type garment has conventionally been formed by putting and bonding a pair of sheets flat together along a margin defining the transition. Particularly for such a disposable type garment, a nonwoven fabric or a plastic film has usually been used as stock material and bonding thereof has often been carried out by means of hot melt adhesive or sealing techniques.
The prior art has already taken account of the fact that the margin for bonding the sheets together should not be dimensioned to be excessively wide. Excessive wide margin for bonding would correspondingly increase an amount of the sheets to be used and, in addition, make the sheets liable to be frayed and/or locally tensioned. Consequently, such excessively wide margin for bonding would make it difficult to obtain a good tailored garment. If the sheets are put flat and bonded together along margins that are dimensioned to be sufficiently narrow, the sheets would have a rigidity along the margin for bonding that is substantially higher than a rigidity of the remaining portions. As a result, the margin for bonding may cause uncomfortable skin stimulation from which the garment wearer suffers. Nevertheless, reduction of the manufacturing cost is essential to the disposable garment and, to meet this requirement, the relatively simple manner of bonding has usually been adopted, i.e., the sheets have been put and bonded flat together.
SUMMARY OF THE INVENTION
It is an object of this invention to alleviate uncomfortable stimulation from which the wearer of a trunks-type garment has conventionally suffered due to the presence of a margin for bonding even when the sheets forming the garment are put and bonded flat together along the margin for bonding in order to form a transition between front and rear bodies of the garment in a crotch region.
The object set forth above is achieved, according to this invention, by a trunks-type garment including a pair of sheets having U-shaped cutouts which are identical to each other in shape as well as in size wherein the pair of sheets are put flat together so as to align said cutouts with each other and respective peripheries of the cutouts put flat are bonded together to form a transition from a front body to a rear body in a crotch region.
The trunks-type garment of the present invention includes the pair of sheets respectively have relatively long extensions which extend outward from edges of the U-shape cutouts at bottoms of respective the U-shaped cutouts and are folded back onto inner surfaces of the sheets forming respective said extensions.
According to one embodiment of this invention, the extensions are folded back so as to describe annular curves in the vicinity of their proximal ends and bonded to the inner surfaces of respective the sheets.
According to another embodiment of this invention, the pair of sheets are made of a nonwoven fabric containing thermoplastic synthetic fibers and bonded to each other along the edges of the cutouts by use of hot melt adhesive or sealing technique.
