ABSTRACT:
The invention pertains to a seal for dispensing wet wipes from a container comprising a tube of generally tapered form having a relatively wide mouth for receiving wipes and a relatively narrow orifice for dispensing them, the tube being divided circumferentially into relatively rigid and relatively flexible axially extending zones, so that when a wet wipe is dispensed the orifice is capable of expansion.
The seal according to the invention provides good dispensing action and prevents to a significant extent evaporation of the impregnated liquid.
