ABSTRACT:
A dosage dispenser comprises a rack having a one-way engagement connection with a piston slidable in a barrel. Reciprocation of the rack is actuated by an obliquely movable slide cammingly engaging the rack and results in incremental advance of the piston to dispense the product, for example toothpaste. The slide is alongside the discharge end of the barrel so the product can be aimed accurately.
