Abstract

A disposable garment of pants type, such as a disposable diaper of pants type, is constructed by attaching respective leg-hole surrounding flaps and waist-hole surrounding flaps to respective opposite side edges extending longitudinally of a basic assembly for the garment which comprises at least a topsheet and a backsheet. The leg-hole surrounding flaps and the waist-hole surrounding flaps respectively cooperate to form a pair of leg-holes. A pair of shoulder straps can be easily prepared by making a slit which extends longitudinally of the garment on each waist-hole surrounding flap. A disposable garment of the present invention is featured in its simple construction and easy production.

Claims

1. A disposable garment of the pants type comprising a basic assembly including at least a liquid-permeable topsheet (2) and a liquid-impermeable backsheet (3), and elastic bands (7) mounted on said basic assembly for partially surrounding a waist-hole, said basic assembly having outlines traversing longitudinally extending opposite side edges (13A, 13B) and transversely extending opposite end edges (12A, 12B) characterized in that each of said opposite side edges (13A, 13B) is provided with a flap (8) and said elastic band (7), said flap (8) surrounding a leg-hole cooperatively with said elastic band (7), an outer side edge of said leg-hole surrounding flap (8) being attached to said basic assembly along one of said opposite side edges (13A, 13B) and end edges (8A, 8B, 7A, 7B) of said leg-hole surrounding flap (8) and said waist-hole surrounding elastic band (7) being attached to said basic assembly by means of bonding lines (10A, 11A, 10B, 11B) provided along the outlines of said garment, said leg-hole surrounding flap (8) and said waist-hole surrounding elastic band (7) overlapping each other at least on said bonding lines (10A, 11A, 10B, 11B) and adjacent thereto with said elastic band (7) being interposed between said leg-hole surrounding flap (8) and said topsheet (2).

3. A disposable garment of the pants type as recited in claim 1 wherein said waist-hole surrounding elastic band (7) is provided with a longitudinal slit therein so as to form a shoulder strap (35).

2. A disposable garment of the pants type comprising a basic assembly including at least a liquid-permeable topsheet (2) and a liquid-impermeable backsheet (3), and elastic bands (7) mounted on said basic assembly for partially surrounding a waist-hole, said basic assembly having outlines traversing longitudinally extending opposite side edges (13A, 13B) and transversely extending opposite end edges (12A, 12B) characterized in that each of said opposite side edges (13A, 13B) is provided with a flap (8) and said elastic band (7), said flap (8) surrounding a leg-hole cooperatively with said elastic band (7), an outer side edge of said leg-hole surrounding flap (8) being attached to said basic assembly along one of said opposite side edges (13A, 13B) and end edges (8A, 8B, 7A, 7B) of said leg-hole surrounding flap (8) and said waist-hole surrounding elastic band (7) being attached to said basic assembly by means of bonding lines (10A, 11A, 10B, 11B) provided along the outlines of said garment, each leg-hole surrounding flap (8) and its adjacent waist-hole surrounding elastic band (7) is formed by providing a single member with a slit.

4. A disposable garment of the pants type as recited in claim 2 wherein said waist-hole surrounding elastic band (7) is provided with a longitudinal slit therein so as to form a shoulder strap (35).

5. A disposable garment of the pants type comprising in combination

(a) a basic assembly that includes at least a liquid-permeable topsheet (2) and a liquid impermeable backsheet (3), outlines of said basic assembly being defined by opposite end edges (12A, 12B) and opposite side edges (13A, 13B),

(b) leg hole flaps (8) extending inwardly from said side edges (13A, 13B), and overlying said basic assembly when the basic assembly is in a flattened condition, the outer side edges of said flaps (8) being attached to said basic assembly along said opposite side edges (13A, 13B) the inner side edges of said flaps (8) being free from said basic assembly so as to form a pocket (30) in cooperation with the topsheet (2) of said basic assembly, said flaps (8) having end edges (8A, 8B) which are joined to said basic assembly adjacent said opposite end edges (12A, 12B) of said basic assembly, and

(c) waist hole bands (7) extending inwardly from said leg hole flaps (7) and also overlying said basic assembly when the basic assembly is in a flattened condition, the end edges (7A 7B) of said waist hole bands (7) being joined to said basic assembly adjacent said opposite end edges (12A, 12B) of said basic assembly, the outer side edges of said bands (7) being unattached to said basic assembly so that the unattached inner sides of said flaps (8) and the unattached outer sides of said bands (7) cooperate to form leg hole openings.

6. A disposable garment according to claim 5 wherein said leg hole flaps (8) contains rubber strips (21) which are attached under stretched condition.

7. A disposable garment of the pants type as recited in claim 5 wherein said attaching lines for the end edges (7A, 7B, 8A, 8B) of said leg-hole surrounding flap (8) and associated said waist-hole surrounding elastic band (7) to said basic assembly define a substantially continuous single line (14A, 14B).

8. A disposable garment as recited in claim 5 wherein each waist hole band (7) and leg-hole flap (8) is formed by providing a single member with a slit.
