Abstract
A pressurized fluid container for use with a cam-activated fluid outlet connector. The container includes a canister, for containing pressurized fluid and a canister cap sealing an end of the canister. The cap includes (i) a base, (ii) a pedestal protruding from the base, the pedestal including a non-cylindrical camming surface adapted to engage a corresponding surface of the cam-activated connector, (iii) a fluid outlet disposed through the pedestal, and (iv) an annular perimeter wall extended from the base around the pedestal, the perimeter wall having a groove therein.

A pressurized fluid container for use with a cam-activated fluid outlet connector, the container comprising:
- a canister, for containing pressurized fluid;
- and
- a canister cap sealing an end of the canister, the cap comprising (i) a base, (ii) a pedestal protruding from the base, the pedestal including a noncircular, cylindrical contact surface adapted to slide axially with respect to the cam-activated connector and to rotate a corresponding surface of the cam-activated connector, (iii) a fluid outlet disposed through the pedestal, and (iv) an annular perimeter wall extending from the base around the pedestal, the perimeter wall having a groove therein for receiving an engaging element of the cam-activated connector.
A pressurized fluid container for use with a cam-activated fluid outlet connector, the container comprising:
- a canister, for containing pressurized fluid;
- and
- a canister cap sealing an end of the canister, the cap comprising (i) a base, (ii) a pedestal protruding from the base, the pedestal including a noncircular, cylindrical contact surface adapted to engage a corresponding surface of the cam-activated connector and adapted to slide axially with respect to the cam-activated connector, (iii) a fluid outlet disposed through the pedestal, and (iv) an annular perimeter wall extending from the base around the pedestal, the perimeter wall having a groove therein, wherein the pedestal has a substantially polygonal cross section.
A pressurized fluid container for use with a cam-activated fluid outlet connector, the container comprising:
- a substantially cylindrical canister, for containing pressurized fluid;
- and
- a canister cap sealing an end of the canister, the cap comprising (1) a base, (ii) a pedestal protruding from the base, the pedestal having a noncircular, cylindrical contact surface having a common axis with the canister, the contact surface adapted to engage a corresponding surface of the cam-activated connector and adapted to slide axially with respect to the cam-activated connector, (iii) an outlet valve disposed through the pedestal, and (iv) an annular perimeter wall extending from the base around the pedestal, the perimeter wall having a groove therein, wherein the pedestal has a substantially polygonal cross section perpendicular to the common axis.
A pressurized fluid container for use with a cam-activated fluid outlet connector, the container comprising:
- a substantially cylindrical canister, for containing pressurized fluid;
- and
- a canister cap sealing an end of the canister, the cap comprising (1) a base, (ii) a pedestal protruding from the base, the pedestal having a noncircular, cylindrical contact surface having a common axis with the canister, the contact surface adapted to slide axially with respect to the cam-activated corrector and to rotate a corresponding surface of the cam-activated connector, (iii) an outlet valve disposed through the pedestal, and (iv) an annular perimeter wall extending from the base around the pedestal, the perimeter wall having a groove therein for receiving an engaging element of the cam-activated connector.
A pressurized fluid container for use with a cam-activated fluid outlet connector, the container comprising:
- a canister containing pressurized fluid;
- a canister cap, the cap comprising (1) a base, (ii) a pedestal protruding from the base, the pedestal including a noncircular, cylindrical camming surface with a regular hexagonal cross section adapted to engage a corresponding surface of the cam-activated connector, (iii) a fluid outlet disposed through the pedestal, and (iv) an annular perimeter wall extending from the base around the pedestal, the perimeter wall having a groove therein;
- and a dip tube hingedly disposed within the canister, depending from and in flow communication with the outlet, the dip tube being weighted sufficiently to insure that a free end of the dip tube will settle within the canister, the dip tube comprising a rigid tubular member and a bendable portion disposed between the outlet and the rigid tubular member.
A coupling system for securing a pressurized fluid container to a cam-activated fluid outlet connector, the coupling system comprising:
- a cap sealing an end of the container, the cap comprising (i) a base, (ii) a pedestal protruding from the base, the pedestal including a noncircular, cylindrical first camming surface, (iii) a fluid outlet disposed through the pedestal, and (iv) an annular perimeter wall extending from the base around the pedestal, the perimeter wall having a groove therein;
- a collet attached to the cam-activated connector comprising a base and a plurality of fingers extending from the base, each finger including a radially extending pawl;
- and
- an aimular cam seated within the collet and rotatable within the collet, the cam having a second camming surface engageable with the first camming surface, the cam including a contact surface which, when the cam is rotated, forces the pawls into the groove.
A pressurized fluid container for use with a cam activated fluid outlet connector, the container comprising:
- a canister, for containing pressurized fluid;
- a canister cap sealing an end of the canister, the cap comprising (i) a base, (ii) a pedestal protruding from the base, the pedestal including a noncircular, cylindrical camming surface adapted to engage a corresponding surface of the cam-activated connector, the pedestal having a substantially polygonal cross section, (iii) a fluid outlet disposed through the pedestal, and (iv) an annular perimeter wall extending from the base around the pedestal, the perimeter wall having a groove therein.
