Abstract

A fluid container having a body for containing fluid, a fluid outlet on a first wall of the body at which the contained fluid exits the body and a filter arranged within the body adjoining the first wall so that the contained fluid passes through the filter before exiting the outlet, wherein the filter is inclined relative to the first wall so that filtered fluid is contained in the body between the filter and the outlet.

Claims (18)

1. A fluid container comprising:

a body having a base and sidewalls for containing fluid;

a fluid inlet;

a fluid outlet defined in a first sidewall of the body;

a float member positioned within the body;

a valve at the inlet;

a valve actuator for selectively opening and closing the valve; and

a filter arranged within the body, said filter adjoining the first sidewall wall so that said contained fluid passes through the filter before exiting the outlet,

wherein the filter is inclined relative to the first sidewall so that filtered fluid is contained in the body between the filter and the outlet, and

wherein the float member is pivotally attached to the valve actuator so that the float member causes the valve actuator to close the valve when the body contains fluid at a predetermined capacity and to open the valve otherwise.

2. A container according to claim 1 , wherein the base of the body beneath the filter adjoins the first sidewall and is substantially parallel to the filter.

3. A container according to claim 1 , wherein the filter comprises a polyester mesh.

4. A container according to claim 3 , wherein the polyester mesh has a pore size of one micron.

5. A container according to claim 1 , wherein an angle between the filter and the first sidewall is 100 degrees.

6. A container according to claim 1 , wherein a base of the float member is configured to conform with the inclined filter.

7. A printer comprising:

an inkjet printhead having an ink inlet;

a container according to claim 1 ; and an ink line connecting the outlet of the container to the inlet of the printhead.
