ABSTRACT:
A child resistant tap has a valve body (12) with an inlet (22) and an outlet (24) and a valve seat (26) therebetween. An axially slidable valve element (28) engages the valve seat (26) to open and close the valve. A handle or lever (1) is pivotally connected to the valve element (28) outside the valve body. The handle has a fulcrum portion (1-2), so that pivotal movement of the handle (1) operates the valve element (28). A safety lever (6) is pivotally attached to the handle (1) and has a locking arm (6-2) which engages the valve body (12) to prevent the handle from pivoting to open the valve. The safety lever (6) also has an actuator arm (6-1) located adjacent to a transverse lever arm (1—1) of the handle, so that squeezing together of the actuator arm (6-1) and the handle lever arm (1—1) causes the safety lever (6) to pivot out of engagement with the valve body (12) allowing the valve to be opened.
