Abstract
Abstract The front barrel of an eye-liner device is tightly fit to an end portion of an outer barrel. A central bore is formed at the center of the front barrel, into which bore a core or brush-type core is inserted. The core is engaged by an end of a spring positioned within the front barrel. Another end of the spring is engaged with a valve member on a knock bar. The valve member engages in a cylindrical valve seat fixed to an inside portion of the front barrel. An ink tank having bellows is connected with the back end portion of the front barrel. The outer surface of the front barrel is fixed to an inside surface of an end portion of an outside cylindrical barrel having an opening through which extends a knocking pin. Fluid ink is fed to the core by pushing the knocking pin.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
106 words
A device comprising a tank including a fluid cosmetic ink, compressible means on said tank and having expanded and compressed states to apply pressure selectively to the ink in said tank, said tank having a discharge opening, a valve means to control the flow of ink through said opening and including a rod extending into said tank to be engaged and displaced by said compressible means for displacement of said valve means, an ink passing core, and barrel means supporting said tank and said core in spaced relationship, said core being fixed relative to said rod and such that the rod moves Relative to said core.
Claim 2
Independent Claim
106 words
A device comprising a tank including a fluid cosmetic ink, compressible means on said tank and having expanded and compressed states to apply pressure selectively to the ink in said tank, said tank having a discharge opening, a valve means to control the flow of ink through said opening and including a rod extending into said tank to be engaged and displaced by said compressible means for displacement of said valve means, an ink passing core, and barrel means supporting said tank and said core in spaced relationship, said core being fixed relative to said rod and such that the rod moves Relative to said core.
Claim 3
Dependent Claim
41 words
A device as claimed in claim 1 comprising a pin extending displaceably through said barrel means for the engagement and compression of said compressible means, said rod being axially spaced from said compressible means in the expanded state of the latter.
Claim 4
Dependent Claim
33 words
A device as claimed in claim 2 wherein said compressible means is a bellows extending from said tank and having collective length therewith, said bellows being less than half of said collective length.
Claim 5
Dependent Claim
51 words
A device as claimed in claim 3 wherein said barrel means includes a first barrel encircling said tank and bellows and a front barrel mounted on the first barrel and supporting said tank in the latter, and a spring in the front barrel to yieldingly resist displacement of said valve means.
Claim 6
Dependent Claim
35 words
A device as claimed in claim 4 wherein said valve means enables the flow of ink from said tank to said core when said compressible means is compressed and said rod displaced towards said core.
Claim 7
Dependent Claim
23 words
A device as claimed in claim 4 comprising perforated washer in said front barrel to limit the passage of ink to said core.
Claim 8
Dependent Claim
16 words
A device as claimed in claim 4 wherein said tank and front barrel are threadably engaged.
Claim 9
Dependent Claim
24 words
A device as claimed in claim 1 comprising a tube extending into said core to accommodate an unimpeded flow of ink into the latter.
