Patent ID: 8033433

Claim:
A dispensing nozzle comprising: (i) an elongate nozzle body having a longitudinal axis and a base portion and a dispensing end; (ii) an internal conduit in the nozzle body for delivering product from the base portion to the dispensing end; (iii) engaging formations on the nozzle for inter-engaging with co-operating engaging formations on a cap, to hold said cap in a position over-fitting the nozzle; (iv) a first set of external ramps, the ramps of the first set being spaced apart on the nozzle transversely relative to the longitudinal axis of the nozzle body; and (v) a second set of external ramps provided longitudinally spaced apart from the first set of external ramps on the nozzle body, the ramps of the second set being transversely spaced apart on the nozzle relative to the longitudinal axis of the nozzle body, and against each of which sets of ramps respective co-operating portions on the cap may act by rotation of the cap with respect to the nozzle in at least one direction, to provide relative force between the cap and the nozzle body, to separate the engaging formations on the cap and the nozzle from an inter-engaged position, wherein the first set of external ramps and the second set of external ramps each comprise a ramping surface oblique to the direction of rotation of the cap.
