ABSTRACT:
An aerosol tilt valve assembly (30, 30') with a valve cup (32) for mounting of a grommet (34) and valve stem (36) includes an annular shoulder (32K, 42A, 42B) formed in the bottom of the cup for strengthening it against distortion from excess aerosol pressures and to otherwise reduce leakage between the valve cup (32) and the grommet (34). In one embodiment, the shoulder (32K) defines a recess for mating receipt of the grommet (34). In another embodiment, the shoulder (42A, 42B) defines a portion of both a reservoir groove (44) and a complementary strengthening rib 42.
