Abstract
A dispensing closure (1) incorporating a flexible, self-closing valve (5) and a transport seal for preventing accidential dispensing of product through the valve during transportation and storage of a filled container. The closure includes a cover (4), which is adapted to move axially between raised and lowered positions, to actuate the transport seal. The transport seal comprises a sealing plate (8), located between the valve and the container opening, which partially occludes the container opening but defines at least one dispensing orifice (9). To form the transport seal, the cover is lowered so that it presses part of the flexible valve against the sealing plate around the dispensing orifice/s, thereby blocking the dispensing passageway to the valve.
