Outlet valve for use with a pressurized fluid container

An outlet valve (700) adapted for use with a pressurized fluid container, the outlet valve (700) comprising:

• an outlet valve chamber (701) including an upper groove (722) and a lower groove (725);
• an outlet valve member (760) configured to move between substantially open and substantially closed positions in the outlet valve chamber (701);
• a non-return member (780) configured to be retained in one of the upper groove (722) or the lower groove (725) in a snap-fit arrangement, wherein when the non-return member (780) is retained in the upper groove (722) the non-return member (780) does not contact the outlet valve member (760) and wherein when the non-return member (780) is retained in the lower groove (725) the non-return member (780) blocks the outlet valve member (760) in the substantially open position;
• and
• an outlet valve actuator (790) configured to contact the non-return member (780) and move the non-return member (780) from the upper groove (722) to the lower groove (725) when the outlet valve (700) is actuated, thereby blocking the outlet valve member (760) in the substantially open position.

A method of forming an outlet valve adapted for use with a pressurized fluid container, the method comprising:

• forming an outlet valve chamber including an upper groove and a lower groove;
• providing an outlet valve member in the outlet valve chamber, with the outlet valve member being configured to move between substantially open and substantially closed positions in the outlet valve chamber;
• and
• providing a non-return member in the outlet valve chamber, with the non-return member being configured to be retained in one of the upper groove or the lower groove in a snap-fit arrangement, wherein when the non-return member is retained in the upper groove the non-return member does not contact the outlet valve member and wherein when the non-return member is retained in the lower groove the non-return member blocks the outlet valve member in the substantially open position.
