Abstract
A method for dispensing a substance including the steps of housing the substance in a container in a substantially flowable state; establishing a path in proximity to the substance for movement of the substance from the container; and applying pressure to the substance within the container to force the substance from the container and along the path. An apparatus for dispensing a flowable substance including a container having an interior adapted to receive the flowable substance; an assembly adapted operably to be connected to the container and having a first passage through which the flowable substance is to be dispensed and communicating with the interior of the container through an opening; an assembly defining a second passage communicating with the interior of the container; and a mechanism for individually pressurizing the first and second passages to cause the flowable substance to be forced from the interior of the container through the opening and into the first passage to be dispensed.
