Patent ID: 8863990

Claim:
A personal care article comprising: (1) a personal care composition comprising a low-shear viscosity of at least 100 cps; the personal care composition being shear-thinning; (2) a manually-actuable, non-aerosol dispensers comprising: (a) a reservoir for holding a liquid to be dispensed in the form of foam; the reservoir comprises a volume such that the reservoir volume is larger than the volume of the personal care composition contained within the reservoir; the reservoir further comprising a headspace, the headspace comprising air; (b) a foamer assembly which can be mounted on or in an opening of the reservoir; the foamer assembly comprises a dip tube, a mixing chamber and a dispensing head; the dip tube extends into the reservoir and into contact with the personal care composition, the dip tube fluidly connecting the mixing chamber with the personal care composition, the mixing chamber fluidly connected to a dispensing head, the dispensing head comprising a foam fluid connection contained within the dispensing head and the dispensing head further comprising a dispensing orifice; the foam fluid connection containing one or more porous elements; the mixing chamber comprises an outer wall which defines an internal volume of the mixing chamber; the outer wall comprises a top edge comprising a circumference; the circumference defining a top area; the mixing chamber further comprising one or more air ingress orifice wherein the total area of the one or more air ingress orifices is from about 0.62 mm 2 to about 3.14 mm 2 , one or more liquid ingress orifices wherein the total area of the one or more liquid ingress orifices is from about 1.5 mm 2 to about 3 mm 2 and one or more mixing chamber egress orifices wherein the total area of the one or more mixing chamber egress orifices is from about 0.314 mm 2 to about 9.42 mm 2 ; wherein the at least one air ingress orifice and at least one liquid ingress orifice are selected such that a ratio of personal care composition to air is from about 1:6 to about 1:15; and wherein the dispenser dispenses a foamed personal care composition comprising a foam specific volume from about 6 mL/g to about 14 mL/g.
