A portable treated material dispenser comprising a portable fluid-tight container, a cylindrically wound roll of sheet material positioned within said portable container and adapted to be impregnated therein with a treating fluid substance, said portable container defining an exit slit adapted to permit gradual withdrawal of said treated sheet material, roller means disposed adjacent said exit slit within said container and adapted to exert pressure upon said sheet material during withdrawal thereof from said container, said sheet material being a web material with relatively large interstices and sad roll means comprising a compressible surface adapted to be deformed by contact with said sheet material during withdrawal thereof.
Claim 3
Dependent Claim
30 words
A portable treated material dispenser according to claim 1 wherein said roller means comprises a pair of parallel engaged roller members adapted to straddle said sheet material during withdrawal thereof.
Claim 4
Dependent Claim
