ABSTRACT:
A moist tissue dispenser in which a web of absorbent sheet material divided by transverse lines of perforations into interconnecting tissue is saturated with a liquid cleansing agent and coiled into a roll having a hollow core, the roll being housed within an open-mouthed container. The leading end tissue of the roll extends upwardly from the core and passes through a frusto-conical central orifice in a removable cover received over the mouth of the container. The orifice functions as a converging passage whose constriction forces the end tissue to rope and to effectively plug the orifice, thereby maintaining the container in a sealed state to prevent evaporation of the cleansing agent. The orifice constriction and its configuration are such as to impose a drag on the roped end tissue as it is pulled from the dispenser by a user and funnelled through the orifice. This drag is insufficient to cause severance of the leading end tissue at its perforation line until the line is advanced beyond the orifice and the exposed tissue is then subjected to a snap action causing separation of the end tissue from the web. The tail of the succeeding tissue now protrudes above the orifice to permit its subsequent extraction.
