Multi-phase oral composition dispenser with adjustable flow

摘要

A flow control device for dispensing a multi-phase oral composition. The device includes a housing, a restrictor and an insert that fits within and cooperates with the housing and restrictor to dispense the oral composition. A flowpath is formed in and around the insert, as well as in the housing such that the composition passes through one or more channels defined by the cooperative arrangement of the insert and housing. Changes in relative position between the insert and the housing facilitate selective alignment of the various channels with a discharge orifice formed in the housing such that a user can vary the way the proportions of discreet fluids making up the oral composition are dispensed through the orifice.

主权项

1. An oral composition dispenser comprising:
a reservoir configured to contain an oral composition made up of a plurality of substantially discreet phases; and a flow control assembly in fluid communication with said reservoir, said flow control assembly comprising:
a housing fluidly coupled to said reservoir and defining a flowpath through which at least a portion of the oral composition dispensed from said reservoir passes, wherein a discharge orifice is provided in said housing; anda restrictor blocking at least a portion of said discharge orifice such that a flow of the oral composition dispensed therethrough is reduced relative to a flow if said restrictor were not present; andan insert disposed within said flowpath and adjustable relative to said housing such that upon relative movement between said insert and said housing, said restrictor cooperates with said discharge orifice to vary relative portions of the discreet phases that are dispensed through said orifice; wherein said reservoir comprises a plurality of material compartments, each to contain at least one of the substantially discreet phases; and wherein at least two of said plurality of material compartments are arranged concentrically relative to one another.
