Abstract
A valve dispenses flowable product from a container. The valve includes a mounting cup for mounting the valve on the container, a seal supported on the mounting cup, and a valve stem extending through the seal. The seal and the valve stem define a generally annular passage section of the valve passage that extends longitudinally along the valve axis radially between the valve stem and the seal. At least one of the valve stem and the seal includes a baffle extending transverse to the valve axis, the baffle defining a flow restriction along the generally annular passage section.
Claims9
A valve for dispensing flowable product from a container comprising:
- a mounting cup for mounting the valve on the container;
- a seal supported on the mounting cup, the seal having an interior surface defining a passage having a longitudinal axis;
- and
- a valve stem received in the passage of the seal, the valve stem including
- a stem body having a longitudinal axis extending longitudinally within the seal, wherein at least a longitudinal portion of the stem body is free from engagement with the interior surface of the seal to define an annular longitudinal passage section therebetween, and
- a baffle extending radially outward from the stem body, wherein a radially outer edge margin of the baffle engages the interior surface of the seal to restrict flow of the flowable product between the radially outer edge margin of the baffle and the interior surface of the seal, wherein the baffle defines an opening extending longitudinally therethrough in communication with the annular longitudinal passage section.
