Ink cartridge plunger |
摘要 |
An improved plunger for a lithographic printing ink cartridge prevents air entrapment between the plunger and the ink when the plunger is pressed into the ink during cartridge assembly. The plunger bottom portion has a positive radius and a textured surface that facilitates the flow of air away from the center of the plunger toward the cartridge sidewall as the plunger is pressed into the ink.
