Abstract: A pressure-activated flexible valve (10) for use with a container for dispensing fluid material such as ink. The valve (10) has a single sealing surface and comprises a base (12) having a valve seat (30) and a cap (14) having an annular rim (50) that seats against the valve seat (30) when the valve (10) is closed. The cap (14) has an annular flexible portion (48) that changes shape in response to pressure from the container material, thereby opening and closing the valve. The valve (10) may be locked closed, and the space between the valve rim (50) and the valve seat (30)can be adjusted to accommodate a variety of fluids, including inks having different viscosities.

Abstract: An improved plunger (40) for fluid dispensing cartridges used in automated dispensing systems. The plunger (40) helps control the reflection of ultrasonic signals used to sense the position of the plunger (40) as it moves within the cartridge tube (60). The plunger (40) has a convex bottom, ink-facing surface (42) and a top surface (48) comprising one or more flat, horizontal surfaces. In the preferred embodiment, the horizontal surfaces are concentric steps (50).
