Abstract

Here are disclosed disposable garments such as a diaper having adhesive areas on top- and/or backsheet(s) along leg-openings. Each of the adhesive areas is defined by a plurality of spiral adhesive traces. The stretchable elastic means are bonded to the top- and/or backsheet(s) along the adhesive areas, respectively.

Claims

1. A disposable garment comprising a topsheet, a backsheet, and stretchable elastic means mounted around spaced apart leg-openings formed on opposite sides of a crotch section defined between front and rear sections of said sheets, spaced apart adhesive areas provided on at least one of said sheets along curved configurations of the leg-openings, each of said spaced apart adhesive areas being composed of a plurality of separated elongated segments of adhesive each segment having a longitudinal axis, each segment consisting of a plurality of connected loops arranged along the longitudinal axis of the segment and portions of said stretchable elastic means are bonded to at least one of said sheets by said spaced apart adhesive areas.

2. A garment as recited in claim 1 wherein substantially all of said stretchable elastic means are stretchable transversely of the longitudinal axes of said adhesive segments.
