摘要

The distributor head for cosmetics in a flexible bottle (2) has an outlet (11) which can be closed by rotating a cap (36). A flexible cup (21) is attached to a piston (26) mounted in a tube (50). As the bottle is squeezed the cup moves between a position where a lip (62) fits against the wall (5), sealing the outlet, and a position where there is a gap and cosmetic is dispensed.
