Claim 1
Independent Claim 220 words
A flexible container containing a stack of towels and adapted for dispensing said towels comprising a moisture impermeable flexible envelope having a resealable opening and said envelope having in the interior space thereof a movable aperatured stiffening plate of an area substantially equivalent to one surface of said envelope and one surface of said towel stack, said plate being positioned between said towel stack surface and said envelope surface so that said aperture is aligned with said resealable opening in the envelope surface, and said towels being stacked and sized so as to be sequentially removable through said aperture and said opening, and said opening having two opposed edges equipped with opposed closure member strips which are attached adjacent to said edges and are adapted so as to interlock and seal said opening under pressure; wherein said resealable opening is centered on an axis of said envelope surface and is large enough to permit a removed towel to be reinserted between said surface and the stiffening plate; a pair of crimped end walls at opposing ends of said resealable opening, and at least one of said end walls having means for suspending said container attached thereto; and wherein said edges may be sealed together so as to form a flange which acts to cover and protect said interlocked closure members.
Claim 2
