Abstract

A two-chamber dispensing package comprises a supply chamber and a discharge chamber. The discharge chamber has a discharge opening closed by means of a self-closing closure and communicates with the supply chamber via an opening. The discharge member has a flexible wall which may be manually deformed to generate a pressure upon the content of said discharge chamber thereby opening said closure and discharging content therefrom. The partition between the two chambers may be a curved flexible wall with an opening and the manual pressure may be exerted upon a wall of the package which thereby covers said opening to give an accurately measured discharge from said discharge chamber.
