Abstract
The present disclosure relates to a valve for dispensing flowable product from a container under pressure, the valve comprising a stem, a seal coupled to the stem, and a mounting cup configured to mount the valve to the container, wherein each of the stem, seal, and mounting cup comprises a recyclable plastic, and wherein the valve is free from a gasket configured to surround an opening of the container to form a seal between the valve and the container. Also provided herein is a container for dispensing a flowable product under pressure comprising the valve as described above.
Claims19
A container for dispensing a flowable product under pressure, the container comprising:
- a container body having an opening and configured to contain the flowable product under pressure therein;
- and
- a valve coupled to the container body at the opening, the valve being selectively openable to allow dispensing of the flowable product from the container body under pressure, the valve including
- a stem including a stem body defining a passage therein, and a disc at a lower portion of the stem body;
- a seal coupled to the stem body, the seal including a seat sealingly engaging the disc of the stem when the valve is closed, a neck extending from the seat and surrounding at least a longitudinal portion of the stem body;
- and
- a mounting cup configured to mount the valve to the container body, the mounting cup including a base and a sidewall extending from the base, wherein the base defines an opening through which the stem and the seal extend such that the sidewall of the mounting cup surrounds at least respective longitudinal portions of the stem body and the neck of the seal,
- wherein each of the container body, the stem, the seal, and the mounting cup comprises a recyclable plastic;
- and
- wherein the stem is biased to an open position under the force of gravity when an upward pressure applied to the disc of the stem is at or below a predetermined threshold pressure.
