Abstract
A method of dispensing fluid or semi-fluid liquids or pastes in which the liquid or paste is contained in a container having a top flexible dome and a bottom dome connected at their open ends to each other. The method comprises pressing the top dome downwardly toward the bottom dome and forcing the top dome into the bottom dome and discharging the liquid or paste from the bottom dome under the action of the forcing of the top dome into the bottom dome. The top dome can be formed with an internal annular bead which is displaced along the inner walls of the bottom dome to scrape off material stuck to the inside walls of the bottom dome.
