Abstract
A liquid dispensing valve including a flexible length of tubing. The tubing is bent along two parallel lines transverse to the axis of the tubing. The tubing is held in an actuator which, in a first position folds the tubing along the two parallel lines to close the tubing to the passage of fluid. In a second position the tubing is partially straightened whereby fluid can pass through the tubing.
Claims5
A dispenser valve for dispensing a liquid from a container wherein the container contains a liquid to be dispensed and a pressurized gas, said dispensing valve comprising:
- a length of flexible tubing, said tubing divided into three segments by two folds along two substantially parallel lines arranged perpendicularly to the axis of said tubing, said folds separated by a section of said tubing, a first said segment movable relative to a second said segment, one end of said tubing adapted to be immersed in said liquid;
- a straightener for selectively retaining said length of tubing in a folded condition to block passage of fluid therethrough and for selectively moving said first segment relative to said second segment to permit fluid to pass therethrough, whereby liquid is selectively dispensed from a said container.
A dispenser valve for a liquid comprising:
- a body including a connector for connecting to a corresponding connector on a bottle;
- a moveable member pivotally connected to said body and including an actuator;
- a spring for urging said moveable member into a first position;
- a flexible tube including an inlet, an outlet and a folded section located intermediate said inlet and outlet and defined by two spaced apart parallel fold lines arranged transverse to the longitudinal axis of said tube, said folded section defining first and second segments of said tubing which are relatively movable with respect to each other, said tube connected to said moveable member to be selectively folded to block passage of fluid therethrough and unfolded to relatively move said first segment with respect to said second segment to thereby permit the passage of fluid therethrough.
