Abstract:
A dispenser has a plunger ( 3 ) operable in a pump body ( 4 ). The plunger can be locked up or locked down, and formations ( 88,89 ) of a pump plunger stem and pump body insert ( 6 ) for achieving this are described. Components of the dispenser, including a pump body cylinder/closure component ( 5 ), container neck and a pump body insert ( 6 ), are rotationally locked together with non-selective alignment and sealed by sliding-fit seals to prevent damage or leakage caused by relative turning of the components in transit.

Claim (Index 1):
Dispenser comprising a pump to be mounted on a neck of a container of a liquid to be dispensed, the pump comprising a body adapted to be mounted on the container neck and a plunger reciprocable in the pump body in a pumping stroke, and wherein the plunger can be locked in a down position relative to the body;\n the pump body comprising a closure that engages the edge of the container neck, a cylinder portion and an insert fitting in the cylinder body, and the plunger comprising a head and a stem; wherein\n (a) the container neck makes a plug fit or sliding seal with the closure portion, and the container neck edge and the part of the closure portion which engages it make a rotational interlock by respective rotational interlock formations which overlap axially in a circumferential direction, to prevent relative rotation thereof, and/or \n (b) the insert and the cylinder portion make a rotational interlock by means of, on at least one of the insert and cylinder portion where they engage one another, respective rotational interlock formations such as a circumferential series of one, two or multiple projecting lugs with intervening recesses, engageable by one, two or multiple corresponding projections on the other of the insert and cylinder portion, and \n (c) a rotational interlock engagement between the plunger and the body in the down position to inhibit release of locking engagement between them.
