A flowable substance dispenser for use with at least one flexible bag, each bag capable of holding one or more flowable substances, the dispenser comprising a hollow tubular body, adapted to receive the flexible bag, and a plunger assembly. The tubular body includes a proximal end, a distal end, an inner periphery, an outer periphery, one or more longitudinal slots, and at least one transverse exit port disposed near the distal end of the tubular body. The plunger assembly includes a piston adapted to slide within the tubular body, a ring member having an inner periphery adapted to fit around the outer periphery of the tubular body, and a transverse bar attached to the inner periphery of the ring member. The bar is adapted to slide within the one or more slots and is capable of engaging the piston.
