Patent ID: 8622260

Claim:
A flow control assembly for a multi-phase oral composition dispenser, said flow control assembly comprising: a housing defining a flowpath therein, said flowpath terminating in a discharge orifice provided in said housing, said flowpath adapted to fluidly engage a reservoir that is formed in the dispenser such that at least a portion of a multi-phase oral composition being dispensed from the reservoir passes through said flowpath and said discharge orifice; a restrictor blocking at least a portion of said discharge orifice such that a flow of the multi-phase composition dispensed therethrough is reduced relative to a flow if said restrictor were not present; and an insert comprising a plurality of channels therein, said insert disposed within said flowpath such that said housing is adjustable relative to said insert such that upon relative movement between them, at least one of said channels fluidly cooperates with said discharge orifice and said restrictor to vary the way at least a portion of the multi-phase composition is dispensed through said flow control assembly; wherein said housing is adjustable relative to said insert by having said housing be selectively rotatable about a composition-dispensing axis defined in said flowpath; wherein said plurality of channels comprise an inner channel fluidly coupled to a first phase of the multi-phase composition and at least one outer channel fluidly coupled to a second phase of the multi-phase composition; and wherein said restrictor is cooperative with said insert such that upon said relative movement between said housing and said insert, said restrictor may completely block one of said inner and outer channels; and wherein ribs define numerous fluid channels over the portion of the flowpath that is occupied by the insert.
