| 摘要 |
The invention provides a miniature capsule-like cartridge having a hollow elongated generally cylindrical body having an inner wall with a substantially uniform diameter. The inner wall encloses a chamber. One end of the body is open and formed at the extremity thereof with an annular circular exterior flange. The opposite end of the body is closed by an end wall. A discharge nipple integrally connected to the body and has a passageway therethrough extending from the chamber at the closed end of the body to facilitate discharge of a polymerizable dental composition from the cartridge. The nipple has an outer wall. The outer wall has a proximal diameter proximal to the body and a medial diameter at a medial position along the central axis of the nipple and medial to the body. The medial diameter is greater than or equal to the proximal diameter. A cup-shaped cap is removably connected to the discharge nipple on the body to close the opening of the passageway at the outer end of the nipple. The cap extends over the medial position of the nipple. <IMAGE> |
