Abstract
A consumable supply item for an imaging device holds an initial or refillable volume of fresh fluid for use in an imaging device. A housing defines an interior having an expandable fluid receptacle to receive waste fluid from the imaging device. As the fresh fluid depletes in the interior over time, the fluid receptacle expands as it accommodates waste fluid. In this way, a single container can both 1) supply fresh fluid and 2) retrieve waste fluid. When full of fresh fluid initially, the fluid receptacle is empty in a compressed state. Upon fresh fluid leaving the container for the imaging device, waste fluid can begin filling the receptacle. Upon depletion of fresh fluid, the container is full of waste fluid. The container is ready for disposal or recycling.

With reference to Figure 1A and Figure 1B, the supplies container 10 used in an imaging device comprises housing 12.This housing defines inner space 14, and the initial of this accommodating fresh fluid in inner space 14 (such as ink 16) maybe can recharge supply.This fluid can be any kind, but typical fluid is water color ink, such as those ink of filling a prescription based on dyestuff or pigment.This fluid also represents shades of colour, such as, and blue-green, carmetta, yellow, black etc.In many application of such as inkjet printing and so on, this supplies is useful, but certainly in administration, formation circuit patterns, Food processing, chemistry manufacture etc., adopts other fluids to be also useful.
During use, the volume of ink downwardly basal surface 18 in enclosure interior space and emptying on the direction of gravity G.This basal surface normally flat or tilt so that ink is derived outside (funnel) to inner space in funnel mode.Ink flows to imaging device by fresh fluid discharge port 20.Breather port 22 provides the suction to around recirculation air or other air, to overcome the counter-pressure in the inner space 14 that increases during imaging operation.These ports can be any kind, typically column tube 24, and this column tube 24 cuts out (Fig. 1 C) by internal ball 26 and spring 28 bias voltage.They coordinate with the barrier film pin 30 from imaging device.This pin is inserted into overcome the bias voltage of spring in these ports, and this ball slides backward.When fully inserting, the opening in port is communicated with pin 32,34, and fluid passage is opened between the inner space 14 and pin of housing.Fluid passage can be air duct or fluid passage.
