Abstract
Abstract An instrument for applying fingernail polish or the like having shiftable and interrelated parts, which automatically open a fluid passage from a reservoir to a brush element when a cover cap is removed and the main body of the instrument is squeezed, and which automatically close said passage and seal the brush element in a closed zone when the cover cap is emplaced on the main body.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
131 words
A liquid applicator instrument comprising: a hollow body adapted to contain said liquid and having an open extremity; a nozzle assembly mounted in the open extremity of the body and including relatively shiftable stem and ferrule elements; liquid passage means through the nozzle, said passage means being open when said elements are in one relative position thereof and closed when said elements are in another relative position thereof; brush means mounted on the nozzle assembly and disposed to receive liquid from the passage means when the latter is open; and cap means Removably mountable on the body in covering relationship to said brush means, said cap means being engagable with the nozzle assembly when the cap means is on the body for relatively shifting said elements to close the passage means.
Claim 2
Dependent Claim
131 words
A liquid applicator instrument comprising: a hollow body adapted to contain said liquid and having an open extremity; a nozzle assembly mounted in the open extremity of the body and including relatively shiftable stem and ferrule elements; liquid passage means through the nozzle, said passage means being open when said elements are in one relative position thereof and closed when said elements are in another relative position thereof; brush means mounted on the nozzle assembly and disposed to receive liquid from the passage means when the latter is open; and cap means Removably mountable on the body in covering relationship to said brush means, said cap means being engagable with the nozzle assembly when the cap means is on the body for relatively shifting said elements to close the passage means.
Claim 3
Dependent Claim
19 words
The invention of claim 1, wherein is provided means for yieldably biasing said elements toward their passage-opening relative position.
Claim 4
Dependent Claim
35 words
The invention of claim 1, wherein said body is constructed of yieldable material and is manually compressable for forcing liquid from the interior of said body through said passage means and onto said brush means.
Claim 5
Dependent Claim
26 words
The invention of claim 1, wherein said stem element is fixedly mounted on said body; and said ferrule element is reciprocable relative to said stem element.
Claim 6
Dependent Claim
27 words
The invention of claim 4, wherein said body and said ferrule element are provided with cooperating interengagable parts for limiting the reciprocable movement of said ferrule element.
Claim 7
Dependent Claim
43 words
The invention of claim 5, wherein said parts include a pair of spaced, opposed shoulders on said ferrule element, and a flange on said body disposed between said shoulders, the spacing between said shoulders being greater than the corresponding dimension of said flange.
Claim 8
Dependent Claim
44 words
The invention of claim 4, wherein said cap means is threadably mountable on said body, and includes a shoulder surface slidably and rotatably engagable with an opposed surface on said ferrule element for shifting the latter relative to the body and the stem element.
Claim 9
Dependent Claim
34 words
The invention of claim 4, wherein there is provided a compression spring oppositely engaging said elements for urging said elements into their passage-opening relative position when said cap means is removed from the body.
Claim 10
Dependent Claim
73 words
The invention of claim 1, wherein said passage means includes a chamber between said elements, an opening through said stem element communicating said chamber with the interior of said body, and a bore through said ferrule element communicating said chamber with the exterior of the instrument when said cap means is removed, said passage means being interrupted between said chamber and said bore when said elements are shifted to their passage-closing relative position.
Claim 11
Dependent Claim
21 words
The invention of claim 9 wherein said brush means is mounted on said stem element and extends outwardly through said bore.
