ABSTRACT:
A dispensing package such as a grease cartridge is made up of a one piece tubular cartridge body and a puncturing end cap. One end of the cartridge body is open and the other end has an imperforate endwall formed with an annular severing zone which surrounds a central cut out panel. The end cap is formed with an interiorly disposed puncturing structure and is adapted to close off the open end of the filled cartridge body. To ready the cartridge for dispensing as in a grease gun, the end cap is removed from the cartridge open end and reapplied over the cartridge closed end. The end cap is then employed to pierce the severing zone of the cartridge endwall and effect removal of the central cut out panel.
