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.
Claims15
A valve for dispensing flowable product from a container, the valve having a valve passage extending along a valve axis, the valve being configured so that the flowable product in the container is passable through the valve passage when the valve is opened to discharge the flowable product from the container, the valve comprising:
- 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, wherein the seal and the valve stem define an annular passage section of the valve passage that extends longitudinally along the valve axis radially between the valve stem and the seal;
- wherein the valve stem comprises a baffle extending transverse to the valve axis, the baffle defining a flow restriction along the annular passage section,
- wherein the baffle has first portion and a second portion diametrically opposite the first portion with respect to the valve axis,
- wherein the first portion of the baffle has a first circumferential side, a second circumferential side, and a radially outer edge margin extending from the first circumferential side to the second circumferential side,
- wherein the second portion of the baffle has a first circumferential side, a second circumferential side, and a radially outer edge margin extending from the respective the first circumferential side to the respective second circumferential side,
- wherein the radially outer edge margin of the first portion of the baffle opposes a first circumferential segment of the seal,
- wherein the radially outer edge margin of the second portion of the baffle opposes a second circumferential segment of the seal,
- wherein the first circumferential side of the first portion of the baffle, the second circumferential side of the second portion of the baffle, and a third circumferential segment of the seal define a first restricted opening through which the flowable product is passable across the baffle, and
- wherein the first circumferential side of the second portion of the baffle, the second circumferential side of the first portion of the baffle, and a fourth circumferential segment of the seal define a second restricted opening through which the flowable product is passable across the baffle.
