A capsule (20) construction for dispensing the entire volume of dental composite material (M) contained therein, wherein the capsule includes a body portion (21) defining a reservoir for containing a predetermined amount of dental material and having an opening at one end (24) and a connected angularly disposed discharge nozzle (26) with a passageway extending therethrough terminating at a discharge orifice (27) at the other end of the body portion (21). A displaceable piston (25) in the form of an elongated rod or cylinder seals the open end (24) of the capsule body portion (21). The piston (25) is formed of a flexible material which is sufficiently rigid to extrude the material within the reservoir when displaced, e.g. by a syringe device, yet sufficiently flexible to negotiate the angular turn at the nozzle end so as to extend through the passageway of the discharge nozzle (26) to effect the extrusion of all of the material (M) contained within the reservoir. <IMAGE> |
