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.

A valve for dispensing flowable product from a container body under pressure, the valve comprising:
- a stem including a stem body and a disc at a lower portion of the stem body;
- a seal coupled to the stem body, the seal including a seat on which an upper surface of the disc is configured to sealingly engage to close the valve, and 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, 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,
- wherein the stem is longitudinally movable relative to the seal under force of gravity to an unseated position, in which the disc of the stem is unseated and spaced apart from the seat of the seal in a downward direction, when an upward pressure applied to a lower surface of the disc of the stem is at or below a predetermined threshold pressure.
A valve for dispensing flowable product from a container body under pressure, the valve comprising:
- a stem including a stem body and a disc at a lower portion of the stem body;
- a seal coupled to the stem body, the seal including a seat on which an upper surface of the disc is configured to sealingly engage to close the valve, and 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, 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,
- wherein the stem is biased to an open position under the force of gravity when an upward pressure applied to a lower surface of the disc of the stem is at or below a predetermined threshold pressure.
A container for a pressurized flowable product comprising:
- a container body having an open top;
- and
- a valve secured to the open top of the container body, the valve including:
- a stem including a stem body and a disc at a lower portion of the stem body;
- a seal coupled to the stem body, the seal including a seat on which an upper surface of the disc is configured to sealingly engage to close the valve, and a neck extending from the seat and surrounding at least a longitudinal portion of the stem body;
- and
- a mounting cup secured to the container, 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,
- wherein the stem is biased to an open position under the force of gravity when an internal pressure in the container body is at or below a predetermined threshold pressure.
