Abstract
An ink supply for a printing system is disclosed which provides a high barrier to air yet is inexpensive to produce. The ink supply includes a chassis having a first and second protrusion. An aperture extends through each of the protrusions to allow fluid communication with a bag; the bag is attached to the chassis so that at least a portion of the first protrusion is surrounded by the bag. Embodiments of the supply include least one air barrier insert, located in the aperture; a septum located in the air barrier; a film attached to the second protrusion and covering the aperture in the protrusion; and a shell which extends around at least a portion of the bag.
Claims55
An ink supply for a printing system comprising:
- a chassis with at least one aperture extending therethrough;
- a bag comprising material that is resistant to air diffusion, wherein the bag is attached to the chassis to allow ink communication from the bag through the aperture in the chassis;
- and
- at least one air barrier insert with an aperture therethrough positioned in the at least one aperture of the chassis.
An ink supply for a printing system comprising:
- a chassis, wherein the chassis comprises first and second protrusions, and wherein an aperture extends through each of the protrusions to allow fluid communication therethrough;
- a bag, wherein the bag is attached to the chassis so that at least a portion of the first protrusion is surrounded by the bag;
- at least one air barrier insert, wherein the air barrier insert is located in the aperture;
- a septum, wherein the septum is located in the air barrier;
- a film, wherein the film is attached to the second protrusion and covers the aperture in the protrusion;
- and
- a shell, wherein the shell extends around at least a portion of the bag.
A printer, comprising:
- an ink supply station comprising a needle, adapted to interface with a replaceable ink supply, wherein the ink supply comprises:
- a chassis, wherein the chassis comprises first and second protrusions, and wherein an aperture extends through each of the protrusions to allow fluid communication therethrough;
- a bag, wherein the bag is attached to the chassis so that at least a portion of the first protrusion is surrounded by the bag;
- at least one air barrier insert, wherein the air barrier insert is located in the aperture;
- a septum, wherein the septum is located in the air barrier;
- a film, wherein the film is attached to the second protrusion and covers the aperture in the protrusion;
- and
- a shell, wherein the shell extends around at least a portion of the bag.
A method of making ink supply comprising:
- attaching a chassis to a bag for containing ink, wherein the chassis comprises a first and second protrusion, and wherein an aperture extends through each of the protrusions to allow fluid communication, and wherein the bag is attached to the chassis so that at least a portion of the first protrusion is surrounded by the bag;
- inserting at least one air barrier insert into the chassis, wherein the air barrier insert is inserted in the aperture;
- inserting a septum into the air barrier;
- attaching a film to the second protrusion so that the film covers the aperture in the protrusion;
- and
- attaching a shell to the chassis so that the shell extends around at least a portion of the bag.
