Abstract
A dispenser apparatus and dispensing method for dispensing a product stored in a container by pressing a dispensing tube connected to the container. A motor rotates a cam that extends a press plate to press the dispensing tube against a back plate. A check valve permits unidirectional dispensing of the product from the container. A pinch-off unit pinches the dispensing tube or a second check valve is used to prevent the product from returning to the container while the press plate presses against the dispensing tube.
