Abstract
A dispenser for viscous or pasty materials comprises a storage container in the form of a flexible tube () and an applicator (). The tube () comprises an elongate, 1-piece hollow moulding of polymeric material, one end of which is closed and formed at the other end of which is an integral dispensing valve defining one or more dispensing slits (). The or each dispensing slit is defined by a respective pair of resilient plates (), which are opposed and inclined to one another and have a respective free edge, the two free edges defining a dispensing slit. The applicator has an applicator surface and one or more passages (), into which the free edges of a respective pair of resilient plates is received. The width of each passage in the applicator is dimensioned such that there is a gap between the free edges of the resilient plates and the associated side surfaces of the passage, when the dispensing slit is closed and so that this gap is substantially closed, when the dispensing slit is opened by the application of pressure to the flexible tube in order to dispense material within the tube.
