Abstract
A valve for dispensing a flowable product from a container includes a mounting cup. The mounting cup includes a bottom wall having a central portion defining a seal-mounting opening through which a seal and a stem extend. An external seal bead of the seal overlies an upper end of the central portion. The upper end of the central portion is disposed at or below a plane extending transverse to a central axis of the mounting cup and defined by a juncture of a sidewall and an annular sidewall-bottom transition portion of the mounting cup.
