Patent ID: 7850384

Claim:
A fluid flow assembly comprising: (a) a storage container having a base and a ball valve assembly axially disposed at said base along a longitudinal axis of said storage container, the ball valve assembly including a spring that biases a valve ball against a sealing gasket; and (b) a fluid coupling and retaining cylinder having a base and an axial hollow elongate fluid outlet co-axially aligned with said ball valve assembly of said storage container, said fluid outlet having a male coupling extending upwardly from said base of said cylinder, wherein when said base of said storage container is connected to said fluid coupling and retaining cylinder, said male coupling penetrates into an outlet port of said ball valve assembly of said storage container, and axially displaces the valve ball of said ball valve assembly against a force of the spring from a closed position into an open position, enabling a fluid flow from said storage container, through said ball valve assembly, into said hollow fluid outlet, the ball valve assembly is located in a cylindrical lower extension that protrudes downwardly from the base of the container, and a complementary co-axial circumferential guide wall extends upwardly from the base of the fluid coupling and retaining cylinder, and the cylindrical lower extension engages in the co-axial circumferential guide wall as the base of the storage container is connected to the fluid coupling and retaining cylinder to guide the male coupling into the outlet port, and a sealing ring is located on the base of the fluid coupling and retaining cylinder when said base of said storage container is disconnected from said fluid coupling and retaining cylinder, and the sealing ring is in contact with a lower surface of the cylindrical lower extension when the base of the storage cylinder is connected to the fluid coupling and retaining cylinder, and when the ball valve assembly is in the open position, the sealing ring provides an additional seal.
