Abstract
A dispensing system and method dispensing flowable materials is disclosed. The system includes a hand-holdable dispensing gun, a holder assembly and a flexible pouch holding a flowable material for dispensing metered amounts of that material. The pouch includes an end portion, which is configured to be torn open to create a mouth for the pouch. The holder assembly includes a tubular member having an outlet including a valve. The tubular member has an open end through which the pouch can be introduced and then a piston cover can then be located in the tubular member to hold the pouch in place. The dispensing gun includes a piston to engage the piston cover and force it into engagement with the pouch to eject a metered amount of the flowable material out of the valve upon each actuation of a trigger of the dispensing gun.
