Liquid Dispensing Tap And Liquid Container Provided With Said Tap

摘要

Liquid dispensing tap 1 connectable to a liquid container 70, e.g. a bag in box, for controlled dispensing of a liquid therefrom. The tap includes a housing 10 forming an inlet of the tap and including a dispensing chamber wall portion 13 delimiting a dispensing chamber 14 with a valve seat 15 at an axial end and forming a dispensing outlet 17 in communication with the dispensing chamber 14. The tap 1 includes a plunger 30 with a stem 31 and a valve portion 32. The stem having an actuator engagement portion 33 outside the dispensing chamber and extending along an axis 15 through a bore 18 in the dispensing chamber wall portion and throughout the dispensing chamber. The plunger moves axially between a closed and an open position. A manually operable plunger actuator 50 engages the engagement portion of the stem to open the tap.
