Claim 9

The closure defined in claim 3 further including an annular seal adapted to be placed between the open edge of the neck of an associated container and the conical surface of said mouthpiece.

Claim 10

The closure defined in claim 3 wherein said apertures are annularly arranged.

Claim 11

The dispensing closure defined in claim 3 wherein said stopper has a hollow interior filled with thermal insulating material.

Claim 12

The dispensing closure defined in claim 9 wherein said stopper is made in two pieces including a body which includes said conical surface portion and said stopper sleeve, and a cap secured on said body.

Claim 13

A dispensing closure for a container or the like, the closure comprising in combination, a mouthpiece having means for securement to the neck of a container, said mouthpiece having an interior sleeve received in the neck of the associated container when the mouthpiece is secured on the latter, said sleeve having projecting outwardly therefrom an inverted conical surface adapted to overlie the neck of the container when the mouthpiece is secured thereon, a stopper having a sleeve mounted in said internal sleeve of said mouthpiece for movement relative thereto, said stopper having a conicaL surface complementary to said conical surface of said mouthpiece and overlying the same, said conical surfaces when spaced from each other forming an annular spout for dispensing contents from an associated container, said conical surfaces adapted to engage each other to prevent dispensing of the contents from an associated container, apertures formed through one of said conical surfaces of said mouthpiece and said sleeve of said stopper for communicating the interior of the associated container with said annular spout for dispensing contents of the associated container, said internal sleeve of said mouthpiece being spaced from the wall of the associated container when the mouthpiece is secured on the container to provide an annular space between the internal sleeve of the mouthpiece and the wall of the container at the neck of the container, an annular seal adapted to be placed between the open edge of the neck of the container and the conical surface of the mouthpiece, said apertures being formed radially through said sleeve of said stopper and being located at a top portion of the sleeve adjacent the conical surface of said stopper, said apertures also being spaced annularly about the sleeve, and wherein the terminal end of said sleeve of said stopper is open permitting the contents of the associated container to move into the interior of the stopper sleeve and through said apertures and into said spot formed by said conical portions when said stopper is initially moved away from said mouthpiece.

Claim 14

A dispensing closure for a container or the like, the closure comprising in combination, a mouthpiece having means for securement to the neck of a container, said mouthpiece having an interior sleeve received in the neck of the associated container when the mouthpiece is secured on the latter, said sleeve having projecting outwardly therefrom an inverted conical surface adapted to overlie the neck of the container when the mouthpiece is secured thereon, a stopper having a sleeve mounted in said internal sleeve of said mouthpiece for movement relative thereto, said stopper having a conicaL surface complementary to said conical surface of said mouthpiece and overlying the same, said conical surfaces when spaced from each other forming an annular spout for dispensing contents from an associated container, said conical surfaces adapted to engage each other to prevent dispensing of the contents from an associated container, apertures formed through one of said conical surfaces of said mouthpiece and said sleeve of said stopper for communicating the interior of the associated container with said annular spout for dispensing contents of the associated container, said internal sleeve of said mouthpiece being spaced from the wall of the associated container when the mouthpiece is secured on the container to provide an annular space between the internal sleeve of the mouthpiece and the wall of the container at the neck of the container, an annular seal adapted to be placed between the open edge of the neck of the container and the conical surface of the mouthpiece, said apertures being formed radially through said sleeve of said stopper and being located at a top portion of the sleeve adjacent the conical surface of said stopper, said apertures also being spaced annularly about the sleeve, and wherein the terminal end of said sleeve of said stopper is open permitting the contents of the associated container to move into the interior of the stopper sleeve and through said apertures and into said spot formed by said conical portions when said stopper is initially moved away from said mouthpiece.
