Patent ID: 7721755

Claim:
A valve assembly for controlling the flow of fluids from a container comprising: a first tube having a cylindrical wall defining a first internal liquid flow path, a first open end of the tube being disposed oppositely a second open end; a second tube having a cylindrical wall defining a second internal liquid flow path, an open third end of the tube being disposed oppositely an open fourth end, a fluid inlet formed in the cylindrical wall intermediate the third end and the fourth end and a fluid outlet formed at the fourth open end, the second open end of the first tube being attached to the fluid inlet such that the first internal liquid flow path is in fluid communication with the second internal liquid flow path, the second tube being transversely disposed to the longitudinal axis of the first tube, the second tube having a pair of circumferentially spaced protrusions extending from an outer surface of the second tube proximate the third end; at least two sealing beads formed on an inside surface of the second tube and being integral therewith, a first sealing bead being located between the third end and the fluid inlet and a second sealing bead being located between the fourth end and the inlet; and a member mounted on the third end of the second tube for rotational movement about an axis of the second tube, the member having a first generally cylindrical wall and a second generally cylindrical wall coaxially disposed and spaced radially inwardly from the first cylindrical wall, the first cylindrical wall having a pair of grooves forming a spiral pattern from a bottom of the first cylindrical wall to a top of the first cylindrical wall, one of each of the pair of protrusions being positioned within one of each of the grooves, and wherein each of the grooves extends through the entire thickness of the first cylindrical wall and an end portion of the protrusions being visible, the first cylindrical wall and second cylindrical wall being integrally formed such that a first edge of the second cylindrical wall is connected to a first edge of the first cylindrical wall by a shoulder element, an opposing second edge of the first cylindrical wall defining an opening between the first and second cylindrical walls, an annular space between the first cylindrical wall and second cylindrical wall extending from the first edge to the second edge, the annular space being coaxially disposed about a portion of the third end of the second tube, and the second cylindrical wall extending axially within the second tube, the member is being moveable from a first, closed position where the second cylindrical wall seals a fluid flow path between the fluid inlet and the fluid outlet to a second open position where fluid is allowed to flow from the fluid inlet though to the fluid outlet.
