Abstract
Abstract An ink supply for a film marking apparatus from which a fast drying ink is obtained for prolonged periods of time without recharging. Recharging is accomplished by replacement of an ink storage container having a foam-like filler spaced from a closed end and exposed to a marking device at an open end through a porous pad and a restricted opening in a porous closure disk.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
115 words
In combination with a movable marking device having a planar sealing surface, an ink absorbent body, a body of liquid ink in contact therewith, a common container for the absorbent body and the ink having an opening into which the marking device is projected, displaceable closure means mounted within the container for intermittant compression of the absorbent body in response to displacement of the marking device, said closure means having an opening closed by the planar sealing surface of the marking device when projected into the container, and an inking pad spacing the absorbent body from the closure means transmitting ink from the absorbent body through the opening in the closure means during displacement thereof.
Claim 2
Dependent Claim
115 words
In combination with a movable marking device having a planar sealing surface, an ink absorbent body, a body of liquid ink in contact therewith, a common container for the absorbent body and the ink having an opening into which the marking device is projected, displaceable closure means mounted within the container for intermittant compression of the absorbent body in response to displacement of the marking device, said closure means having an opening closed by the planar sealing surface of the marking device when projected into the container, and an inking pad spacing the absorbent body from the closure means transmitting ink from the absorbent body through the opening in the closure means during displacement thereof.
Claim 3
Dependent Claim
104 words
An ink storage means for a movable marking device comprising an elongated, non-porous container having a closed end and an open end, an absorbent body of material in said container, means spacing the body of absorbent material from the closed end to form a reservoir chamber for ink and sealing means within the container displaceable by the moveable marking device and engageable with the absorbent material at said open end of the container for inducing flow of ink from the absorbent body and substantially sealing the ink in the container while in contact with the marking device to prevent rapid drying of the ink.
Claim 4
Dependent Claim
104 words
An ink storage means for a movable marking device comprising an elongated, non-porous container having a closed end and an open end, an absorbent body of material in said container, means spacing the body of absorbent material from the closed end to form a reservoir chamber for ink and sealing means within the container displaceable by the moveable marking device and engageable with the absorbent material at said open end of the container for inducing flow of ink from the absorbent body and substantially sealing the ink in the container while in contact with the marking device to prevent rapid drying of the ink.
Claim 5
Dependent Claim
48 words
The combination of claim 2 wherein the displaceable sealing means includes a non-porous closure element at the open end of the container having an opening closed by the marking device while in contact therewith, and a porous pad spacing the body of absorbent material from the closure element.
Claim 6
Dependent Claim
22 words
The combination of claim 3 wherein the container includes means for limiting axial displacement of the sealing means at the open end.
Claim 7
Dependent Claim
41 words
The combination of claim 3 wherein the marking device includes a planar surface displaceable between marking and ink-receiving positions, said planar surface engaging the closure element in the ink-receiving position to axially compress the body of absorbent material within the container.
Claim 8
Dependent Claim
38 words
The combination of claim 5 wherein the marking device further includes type projecting from the planar surface through the opening in the closure element into contact with the porous pad in the ink-receiving position of the marking device.
Claim 9
Dependent Claim
22 words
The combination of claim 6 wherein the container includes means for limiting axial displacement of the closure element at the open end.
Claim 10
Dependent Claim
41 words
The combination of claim 2 wherein the marking device includes a planar surface displaceable between marking and inK-receiving positions, said planar surface engaging the sealing means in the ink-receiving position to axially compress the body of absorbent material within the container.
Claim 11
Dependent Claim
22 words
The combination of claim 8 wherein the container includes means for limiting axial displacement of the sealing means at the open end.
