Claim 1
Independent Claim
334 words
A container cap comprising: a vertical hollow cylinder closed at its upper end and open at its lower end, the cylinder having a hole in the cylinder wall disposed below the upper end; first and second vertical parallel posts secured to the upper end of the cylinder extend downwardly inside the cylinder on opposite sides of the hole, the posts being adjacent the hole and disposed adjacent but spaced apart from the inner surface of the cylinder wall; a vertical hollow cylindrical member disposed rotatably within the cylinder and having an open lower end, the cylinder and member having a common vertical axis; a flat horizontal circular disc secured to and closing the upper end of the member, the center of the disc being aligned with the common axis, the disc having an off center opening and being provided with a vertical upwardly extending peripheral lip which extends partially around the disc, the disc being disposed within the first cylinder in such manner that the lip extends rotatably between the inner surface of the first cylinder and both posts; a short vertical hollow tube open at both ends, the lower end of the tube being flush with the opening in the disc, the tube extending upwardly from the disc; an elongated hollow nozzle having a vertical discharge port at one end and a horizontal intake port at the other end, the nozzle being disposed above the disc with the tube extending through the horizontal port, the nozzle being rotatable about the tube between first and second extreme positions when either one of the cylinder and member is held stationary and the other one is rotated about the common axis, the first position being the open position at which the lip does not close the hole and the nozzle is fully extended outwardly through the hole, the second position being the closed position at which the lip closes the hole and the nozzle is fully withdrawn into the cylinder and is spaced from the hole.
Claim 2
Dependent Claim

A container cap comprising: a vertical hollow cylinder closed at its upper end and open at its lower end, the cylinder having a hole in the cylinder wall disposed below the upper end; first and second vertical parallel posts secured to the upper end of the cylinder extend downwardly inside the cylinder on opposite sides of the hole, the posts being adjacent the hole and disposed adjacent but spaced apart from the inner surface of the cylinder wall; a vertical hollow cylindrical member disposed rotatably within the cylinder and having an open lower end, the cylinder and member having a common vertical axis; a flat horizontal circular disc secured to and closing the upper end of the member, the center of the disc being aligned with the common axis, the disc having an off center opening and being provided with a vertical upwardly extending peripheral lip which extends partially around the disc, the disc being disposed within the first cylinder in such manner that the lip extends rotatably between the inner surface of the first cylinder and both posts; a short vertical hollow tube open at both ends, the lower end of the tube being flush with the opening in the disc, the tube extending upwardly from the disc; an elongated hollow nozzle having a vertical discharge port at one end and a horizontal intake port at the other end, the nozzle being disposed above the disc with the tube extending through the horizontal port, the nozzle being rotatable about the tube between first and second extreme positions when either one of the cylinder and member is held stationary and the other one is rotated about the common axis, the first position being the open position at which the lip does not close the hole and the nozzle is fully extended outwardly through the hole, the second position being the closed position at which the lip closes the hole and the nozzle is fully withdrawn into the cylinder and is spaced from the hole.
Claim 3
Dependent Claim
50 words
The cap of claim 1 wherein the curvature of the said one nozzle end conforms to the curvature of the inner surface of the cylinder wall and wherein said one nozzle end engages the inner surface to seal off the discharge port when the nozzle is in the closed position.
Claim 4
Dependent Claim
30 words
The cap of claim 2 wherein the tube and the opposite ends of the lip, as viewed in a horizontal plane, define points located approximately along a common horizontal line.
Claim 5
Dependent Claim
19 words
The cap of claim 3 wherein the lower end of the tube is sealed to the off set opening.
Claim 6
Dependent Claim
40 words
The cap of claim 4 further including a vertical stop pin secured to the inner surface of the lip and disposed between the ends of the lip to limit the degree of rotation of the nozzle in the closed position.
Claim 7
Dependent Claim
16 words
The cap of claim 5 wherein the nozzle when in the open position engages the posts.
