Abstract: A cartridge for dispensing a material, having: a sleeve having a longitudinal axis and a distal wall with a dispensing hole; a barrel defining a chamber for the material, including a proximal open end and a breakable distal wall at its distal end, and being movable in the sleeve between a first position where its distal wall is a distance from the sleeve's distal wall and a second position where its distal wall's sealing portion contacts an inner surface of the sleeve's distal wall; and a piston having a plate movable to seal the barrel's chamber. The sleeve includes an internal piercing element, near the dispensing hole, for breaking the barrel's distal wall upon moving the barrel from the first to the second position. Around the piercing element is an annular cavity delimited peripherally by a beveled inner surface that complements a beveled outer surface of the barrel.
