A viscous material dispenser for applying a viscous dental material from a
capule, cartridge or capsule. The dispenser includes a locking mechanism
mounted on the syringe type dispenser to securely retain the capule,
cartridge or capsule within the syringe type dispenser while the viscous
material is being applied from the syringe type dispenser. The locking
mechanism can be positioned so that it rotates around and over the outer
circumference of the dispensing barrel of the syringe type dispenser. The
locking mechanism can be rotated to an open position where a capule,
capsule or cartridge can be inserted or removed from the syringe type
dispenser. After a capule, cartridge or capsule is inserted within the
syringe barrel, the locking mechanism can be rotated to a closed position
where the capule, cartridge or capsule is locked and retained in place for
dispensing.
