Tap for a liquid container. |
摘要 |
The tap has a hollow cylindrical body (12) closed by a diaphragm (14) at one end and having a radial outlet (16). A valve closure member (30) is axially movable by pressure on the diaphragm through a mechanism (60) to lift a closure flange (38) off a seat (20). An annular passage (40) is defined between the body wall and a cylindrical wall (35) of the valve closure member to provide laminar flow from the valve seat to the outlet. A conical end (36) of the valve closure member faces the flow of liquid and is surrounded by a frusto-conical wall (53) to define a divergent annular chamber (54) of uniform cross-section leading to the annular passage (40). This chamber reduces in cross-sectional area as the tap is opened. This combination of features substantially prevents swirling and turbulence and permits dispensing of carbonated liquids without loss of carbonation.
