Abstract
A seal member for a dispensing cartridge includes a flat circular seal disk, a frustoconical wall extending outwardly away from the seal disk, and a ring at an open end of the frustoconical wall. The seal member is assembled with a cap having an end wall and a cylindrical skirt wall. The skirt wall has an internal diameter and the ring has a slightly smaller outer diameter. The ring abuts the end wall. A central opening extends through the end wall with a diameter no larger than a ring inner diameter. The dispensing cartridge has a cylindrical mouth wall with inner and outer diameters. The skirt wall has an internal diameter sized to receive the mouth wall outer diameter and the diameter of the seal disk is larger than the mouth wall inner diameter. The ring outer diameter is at least equal to the mouth wall outer diameter.
