A dental cartridge or capsule for dispensing a dental material, such as an amalgam, cement, or glass ionomer. A body portion has a reduced diameter end. A frangible seal is placed adjacent or within the reduced diameter end. A delivery portion or cap has a metal cannula extending there through. The delivery portion or cap is snap fit onto the reduced diameter end. The metal cannula is positioned within the delivery portion or cap so as to rupture the frangible seal in the reduced diameter end of the body portion when the delivery portion or cap is snap fit onto the reduced diameter end. A material placed within the body portion of the dental cartridge is sealed within the body portion, and prevented from entering and thereby possibly clogging the delivery portion of the dental cartridge having a relatively small diameter bore or lumen prior to placement of the delivery portion or cap. In another embodiment the frangible seal is formed by a twist-off tab at the end of the reduced diameter portion. The mixing of a first component, typically a powder, and a liquid component of a dental material is greatly facilitated.
