<p>A dispensing package (1) for cream compositions comprising (a) a container body (2) having a longitudinal central axis; (b) the container body defining a storage chamber (9) for the composition; (c) an opening (7) in the container body for discharging the composition; (d) a fixed cam (25) opposite said opening having teeth (26) orientated tangentially to said longitudinal axis; (e) rotatable cog (18) mounted on said cam having a plurality of ratchet teeth (20) engageable with the teeth of said fixed cam; (f) the cog being provided with external peripheral cams (19) oriented parallel with said longitudinal axis; (g) a spindle (21) mounted on said cog and extending along said central longitudinal axis between the cog and the opening; (h) an elevator (36) mounted on said spindle and displaceable between the cog and the opening (7) to dispense the composition through the opening; (i) a pawl (30) oriented transverse to the longitudinal axis and engageable with said peripheral cams to rotate the cog and spindle on the fixed cam; and (j) an actuator button (12) attached to said pawl to urge the pawl against the peripheral cam, such that, upon actuation of the button, the cog and spindle ride on the fixed cam with a reciprocating motion which is transferred to the elevator via the spindle.</p> |
