A sipper type capping assembly engageable with a necked container so as not to pool condensation on the disc seal. It has a unitary moulding ( 1 ) adapted to define a detachable overcap ( 4 ) and at least the container engaging skirt ( 9 ). An insert ( 2 ) and a disc seal member ( 17 ) located within moulding ( 1 ), and a nozzle component ( 3 ) above the seal member is carried through the insert yet moveable relative thereto. In a non-dispensing condition, the nozzle component ( 3 ) and the insert ( 2 ) provide closure. In the dispensing condition of the nozzle component ( 3 ) relative to the insert ( 2 ) there is defined a liquid egress passageway. The insert and the nozzle component, when in or notionally considered in the non-dispensing condition, define together with the moulding a fully enclosed space about part of the nozzle component. When in or notionally considered in at least the dispensing condition, the moulding and the disc seal member fully enclose the nozzle component.
