    摘要： A method of venting during sealing the cartridge. The cartridge body has an external wall, a generally cylindrical internal chamber wall having an internal chamber wall diameter and enclosing a cartridge chamber, and at least one channel wall forming a channel (or groove) in the chamber wall. The piston has a generally cylindrical plug wall positioned adjacent to the generally cylindrical internal chamber wall. The cylindrical plug wall has a diameter substantially equal to the diameter of the cylindrical internal chamber wall. Dental material is conveyed into the cartridge chamber. The piston is pressed into the cartridge chamber while venting gas from the cartridge chamber through the channel prior to forming a hermetic seal around the dental material in the cartridge chamber.
