Abstract
A disposable undergarment having a tape fastener for releasably joining front and rear regions of the undergarment to each other is disclosed. The tape fastener includes a relatively soft base panel member extending laterally outward from a transverse side edge of the undergarment, relatively rigid fastening panel members provided at longitudinally spaced apart locations of the base panel member and an adhesive region provided between the fastening panel members.
Claims9
In a disposable undergarment having a front waist region and a rear waist region and at least one tape fastener connected to secure the regions together during use, the improvement comprising:
- said tape fastener including a relatively soft base panel member extending laterally outward from a transverse side edge of said rear waist region and having a base end and a free end, inner and outer surfaces and upper and lower edges, and at least two relatively rigid fastening panel members having a plurality of one hook elements and loop elements provided at longitudinally spaced apart locations on the inner surface between the upper and lower edges of said base panel member, and an adhesive region provided on the inner surface of said base panel member between said fastening panel members;
- said fastening panel members being fixedly bonded to the inner surface of said base panel member;
- and
- a fastening region having a plurality of the other of said hook elements and loop elements provided on an outer surface of said front waist region to be releasably engaged with said fastening panel members, wherein said fastening panel members are arranged such that, even if one of the spaced apart fastening panel members is inadvertently disengaged from said fastening region with a disengaging force, the other one of said fastening panel members is unaffected by the disengaging force to thereby remain in fastening contact with said fastening region, and wherein said adhesive region is provided between said fastening panel members to enable a soiled said disposable undergarment to be rolled up and remain in a rolled condition with said adhesive regions.
In a disposable undergarment having a front waist region and a rear waist region and at least one tape fastener connected to secure the regions together during use, the improvement comprising:
- said tape fastener including a relatively soft base panel member extending laterally outward from a transverse side edge of said rear waist region and having a base end and a free end, inner and outer surfaces and upper and lower edges, and at least two relatively rigid fastening panel members having a plurality of hook elements provided at longitudinally spaced apart locations on the inner surface between the upper and lower edges of said base panel member and which are transversely dimensioned so as to be relatively narrow in the proximity of the upper and lower ends of said base panel member and relatively large at a vertical mid-portion thereof between the upper and lower ends of said base panel member, said fastening panel members being fixedly bonded to the inner surfaces of the base panel member by a hot melt adhesive and heat-sealed partially to the inner surface of the base panel member, and an adhesive region provided on the inner surface of said base panel member between said fastening panel members;
- and
- a fastening region having a plurality of loop elements provided on an outer surface of said front waist region to be releasably engaged with said fastening panel members.
