Abstract
Abstract An implement for applying a liquid comprises a container having an opening at its front end, a front tube attached to the container forward end, a hollow accommodating member having a chamber in its interior and formed with a rearward communication hole and a forward communication hole for holding the chamber in communication with the interior of the container and the interior of the front tube respectively, a liquid feed member accommodated in the chamber and movable axially thereof, a biased end valve disposed inside the front tube providing a liquid retaining portion inside the front tube around the end valve for closing the forward end opening of the front tube, and an applicator having a capillary action extending through the forward end opening of the front tube and secured to the front end of the end valve.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
294 words
An implement for applying a liquid comprising: an elongated container having a forward end which is open; a front member attached to said forward end of said container, said front member having a longitudinal axis and an axially extending front tube having a forward end with an outlet opening; an elongated accommodating member disposed within said container and extending into said front member, said accommodating member having an interior chamber having a rearward opening communicating with said container and a forward opening communicating with said front member; a liquid feed member disposed in said interior chamber of said accommodating member, said accommodating member having a longitudinal axis, said feed member being axially movable in said interior chamber; an end valve axially movable in said front tube between open and closed positions, a narrow retaining passage between said end valve and said front tube, said end valve in said open position allowing liquid to pass from said narrow retaining passage out through said outlet opening of said front tube, said end valve in said closed position closing off said outlet opening of said front tube, biasing means in said front tube for biasing said end valve toward said closed position; said feed member being axially and reciprocably movable in said interior chamber upon manually shaking of the implement such that liquid in said interior chamber is forced into said narrow retaining passage via said front opening in said accommodating member; and an applicator secured to said end valve and extending through said outlet opening of said front tube such that when said end valve is in said open position, the liquid in said retaining passage is drawn out by capillary action through said outlet opening to said applicator to be applied to a receiving surface.
Claim 2
Dependent Claim
294 words
An implement for applying a liquid comprising: an elongated container having a forward end which is open; a front member attached to said forward end of said container, said front member having a longitudinal axis and an axially extending front tube having a forward end with an outlet opening; an elongated accommodating member disposed within said container and extending into said front member, said accommodating member having an interior chamber having a rearward opening communicating with said container and a forward opening communicating with said front member; a liquid feed member disposed in said interior chamber of said accommodating member, said accommodating member having a longitudinal axis, said feed member being axially movable in said interior chamber; an end valve axially movable in said front tube between open and closed positions, a narrow retaining passage between said end valve and said front tube, said end valve in said open position allowing liquid to pass from said narrow retaining passage out through said outlet opening of said front tube, said end valve in said closed position closing off said outlet opening of said front tube, biasing means in said front tube for biasing said end valve toward said closed position; said feed member being axially and reciprocably movable in said interior chamber upon manually shaking of the implement such that liquid in said interior chamber is forced into said narrow retaining passage via said front opening in said accommodating member; and an applicator secured to said end valve and extending through said outlet opening of said front tube such that when said end valve is in said open position, the liquid in said retaining passage is drawn out by capillary action through said outlet opening to said applicator to be applied to a receiving surface.
Claim 3
Dependent Claim
35 words
An implement according to claim 1, wherein said accommodating member has a forward tapered guide portion leading to said forward opening, said tapered guide portion decreasing in cross-sectional area as said forward opening is approached.
Claim 4
Dependent Claim
46 words
An implement according to claim 1, wherein said accommodating member has seating means juxtaposed to said forward opening, said liquid feed member being seatable on said seating means to preclude flow of liquid from said interior chamber of said accommodating member out through said forward opening.
Claim 5
Dependent Claim
40 words
An implement according to claim 3, wherein said seating means has a frusto-conical configuration having a large diameter end and a small diameter end, said small diameter end being disposed closer to said forward opening than said large diameter end.
Claim 6
Dependent Claim
98 words
An implement according to claim 1, wherein said interior chamber of said accommodating member has a forward interior end and a rear interior end, said liquid feed member being axially reciprocable in said interior chamber between forward and rear positions, said liquid feed member contacting said forward interior end when in said forward position, said liquid feed member contacting said rear interior end when in said rear position, said rearward opening in said accommodating member providing communication between said container and said interior chamber of said accommodating member when said liquid feed member is in said rear position.
Claim 7
Dependent Claim
19 words
An implement according to claim 1, wherein said rearward opening in said accommodating member comprises an axially extending slit.
Claim 8
Dependent Claim
