Abstract
An apparatus for automatically dispensing flowable material which automatically ensures a substantially constant and even supply of flowable material from a source of the flowable material to some destination at which the flowable material needed or is used. The flowable material may be any material that can be extruded from a collapsible tube upon the exertion of pressure on the tube and includes liquids or gels. The apparatus comprises a collapsible tube having a nozzle end and a sealed end and containing a flowable material; a tube squeezer; a rotatable drum for pulling the collapsible tube through the tube squeezer as the drum rotates; a motor for rotating the drum; and an electronic feedback mechanism for disengaging the motor so as to maintain pressure of the flowable material within a selected pressure range and the supply of flowable material to a destination is substantially even and constant.
