Abstract

A dispensing assembly for at least two constituents is provided having flexible walls and at least two compartments, including outlet orifices located adjacent to one another so that when the outlet orifices are opened as by cutting, and pressure is applied to the flexible walls, dispensing and immediate mixing of the constituents will be effected; the viscosity and volumes of the constituents are selected to have certain values to enable the dispensing to properly mix the constituents to form a homogenous product.
