Abstract:
A packaged antiperspirant cream composition having a penetration force value of from about 75 gram.multidot.force to about 500 gram.multidot.force, wherein the composition comprises:(a) from about 10% to about 80% by weight of a liquid carrier;(b) from about 0.5% to about 35% by weight of an antiperspirant active;(c) from about 0. 1% to about 40% by weight of a gellant; and(d) a dispensing package containing the antiperspirant cream composition, wherein the dispensing package comprisesi) a container body having an interior chamber having a lengthwise extending axis and which contains the antiperspirant cream composition, and a cross sectional area of the interior chamber perpendicular to the extending axis having a ratio of a major axis to minor axis of the cross sectional area from about 1.7:1 to about 5:1;ii) an elevator having a cross section congruent to and mounted for axial movement within the interior chamber;iii) a perforated dome attached to a dispensing end of the container body and having a plurality openings extending through the thickness of the perforated dome and covering from about 15% to about 80% of the total surface area of the perforated dome; andiv) a means for axially advancing the elevator toward the perforated dome and a means for axially reciprocating the elevator away from the perforated dome, said means for axially advancing the elevator and said means for axially reciprocating the elevator cooperating to retract the elevator away from the perforated dome a minimum distance for each predetermined increment of forward axial advancement of the elevator by the means for axially advancing toward the perforated dome, wherein the minimum retracting distance is determined by the expression D.sub.min =[V.sub.max -V.sub.rest ]/A wherein D.sub.min is the minimum retracting distance, V.sub.max is the maximum volumetric deformation of the container body during extrusion, V.sub.rest is the volumetric deformation of the container body prior to extrusion and ""A"" is the cross sectional area of the container body.
