Claim 12:
13. A container for dispensing a flowable product under pressure, the container comprising:
a container body having an opening and a lip adjacent the opening, the container body configured to contain the flowable product under pressure therein; and
a valve coupled to the container body to close the opening, the valve being selectively operable to dispense the flowable product from the container body, the valve including
a mounting cup coupled to the container body, the mounting cup including
an annular inner wall having upper and lower ends, the annular inner wall defining a central axis of the mounting cup, the annular inner wall being positioned in the opening of the container body;
a base extending radially inward from adjacent the lower end of the inner wall toward the central axis of the mounting cup;
a continuous retaining ring radially spaced apart from the annular inner wall, wherein the container body is positioned between the annular inner wall and the continuous retaining ring; and
a plurality of detents on the continuous retaining ring and extending radially inward toward the annular inner wall, the detents engaging an underside of the lip of the container body to secure the mounting cup to the container body,

wherein the container is free of a separate gasket forming a seal between the lip of the container body and the mounting cup,
wherein the annular inner wall is configured to bow radially outward under pressure and push against the interior surface of the container body to form a leak proof seal between the mounting cup and the container body.
