Abstract
Abstract A disposable ink cartridge for use in automatic marking systems. The ink cartridge is composed of a housing which contains a collapsible elastomeric ink reservoir having an open end secured to a plurality of barrier disks. The barrier disks are apertured to permit passage of ink through and between them, from the reservoir. An ink absorbing member of fibrous or porous material is positioned at the other, outlet end of the cartridge housing. The ink cartridge provides a constant flow of ink when the ink absorbing member is contacted by a print head or the like until the supply of ink is depleted from the reservoir. The cartridge design permits depletion of essentially the entire reservoir under the above conditions.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
158 words
An ink applicator device comprising a collapsible reservoir for storing a supply of ink having an open end; a container for said reservoir; an ink-absorbing member located at the outlet end of said applicator device; and barrier means located between the ink-absorbing member and the reservoir for regulating the flow of ink from said reservoir to said ink-absorbing member; said barrier means comprising a plurality of disks having a plurality of apertures through which ink can flow, said disks coaxially juxtaposed so that the apertures of adjacent disks are in substantial nonalignment and said disks being in nonadhesive contact; wherein the container has at least one air vent thereby exposing the reservoir exterior surface to ambient pressure; wherein upon external ink removal from the ink-absorbing member, ink flows from the reservoir through said nonaligned apertures of the disks to the ink-absorbing member creating a partial vacuum in the reservoir partially collapsing the reservoir around the remaining ink therein.
Claim 2
Dependent Claim
158 words
An ink applicator device comprising a collapsible reservoir for storing a supply of ink having an open end; a container for said reservoir; an ink-absorbing member located at the outlet end of said applicator device; and barrier means located between the ink-absorbing member and the reservoir for regulating the flow of ink from said reservoir to said ink-absorbing member; said barrier means comprising a plurality of disks having a plurality of apertures through which ink can flow, said disks coaxially juxtaposed so that the apertures of adjacent disks are in substantial nonalignment and said disks being in nonadhesive contact; wherein the container has at least one air vent thereby exposing the reservoir exterior surface to ambient pressure; wherein upon external ink removal from the ink-absorbing member, ink flows from the reservoir through said nonaligned apertures of the disks to the ink-absorbing member creating a partial vacuum in the reservoir partially collapsing the reservoir around the remaining ink therein.
Claim 3
Dependent Claim
18 words
An ink applicator as in claim 1 wherein the ink absorbing member is comprised of nonwoven fibrous material.
Claim 4
Dependent Claim
23 words
An ink applicator as in claim 1 wherein the ink absorbing member is comprised of a porous plastic having an open cell structure.
Claim 5
Dependent Claim
43 words
An ink applicator as in claim 1 wherein the ink absorbing member comprises a member of nonwoven fibrous material in contact with said barrier means and a porous plastic member having an open cell structure at the outlet of said ink applicator device.
Claim 6
Dependent Claim
27 words
An ink applicator as in claim 1 wherein the total volume of the ink absorbing member is substantially less than the maximum ink capacity of said reservoir.
Claim 7
Dependent Claim
17 words
An ink applicator as in claim 1 wherein the collapsible reservoir is comprised of an elastomeric material.
Claim 8
Dependent Claim
15 words
An ink applicator as in claim 6 wherein the reservoir is comprised of latex rubber.
