US 2001/0018581 A1 · SURFACE FASTENER AND PAPER DIAPER USING THE SURFACE FASTENER

Abstract

A surface fastener having a first substrate sheet having on its front surface hook-shaped engaging elements and on its rear surface a low-adhesion adhesive double coated tape to an outer surface of which a backing sheet is adhered, and a second substrate sheet having on its front surface loop-shaped engaging elements and on its rear surface an adhesive layer to an outer surface of which a peel paper is adhered. For attaching the surface fastener to a paper diaper, the adhesive layer of the second substrate sheet is adhered to a front covering portion of the diaper, while the adhesive double coated tape of the first substrate sheet is adhered to an attachment strip of a hip covering portion of the diaper after the backing sheet is peeled off. When casting off the diaper after using, the adhesive double coated tape is separated from the first substrate sheet so as to be left on the attachment strip and then the diaper is folded, whereupon the adhesive double coated tape on the attachment strip is adhered to an outer surface of the folded diaper to wrap up the diaper.

Dependent claims

A surface fastener comprising:

(a) a first substrate sheet having front and rear surfaces, the first substrate sheet having on its front surface a multiplicity of first engaging elements and on its rear surface a first adhesive layer;
(b) a second substrate sheet having front and rear surfaces, the second substrate sheet having on its front surface a multiplicity of second engaging elements engageable with said first engaging elements and on its rear surface a second adhesive layer;
(c) the first adhesive layer having an adhesive strength smaller than that of said second adhesive layer and smaller than an engaging strength of the first and second engaging elements when the first and second engaging elements are engaged with each other.

A paper diaper comprising:

a unitary diaper body having a front covering portion having opposite free sides and a hip covering portion having opposite free sides, said hip covering portion having two attachment strips respectively disposed at said opposite sides, and two surface fasteners respectively releasably fastening said opposite free sides of said front covering portion to said opposite free sides of said hip covering portion, each of said fasteners comprising:
(a) a first substrate sheet having front and rear surfaces, the first substrate sheet having on its front surface a multiplicity of first engaging elements;
(b) a second substrate sheet having front and rear surfaces, the second substrate sheet having on its front surface a multiplicity of second engaging elements engageable with said first engaging elements and on its rear surface an adhesive layer adhered to one of said opposite free sides of said front covering portion;
and
(c) an adhesive double coated tape adhered to the rear surface of said first substrate sheet with an adhesive strength smaller than that of said adhesive layer and smaller than an engaging strength of the first and second engaging elements when the first and second engaging elements are engaged with each other, said adhesive double coated tape being adhered to one of said attachment strips of said hip covering portion.
