Abstract
Abstract A dispensing port in a wall of a container 10 for dispensing perforated sheets. The dispensing port comprises three slots 62 generally extending radially from a central opening 61 of the dispensing port to form three flexible, triangular flaps 56, the apex 58 of each flap 56 being rounded. The flaps 56 apply tension to a leading sheet being pulled through the slots 62 to cause the leading sheet to be separated from the next sheet at the perforations while leaving a tip 75 of the next sheet projecting through the dispensing port.
