Hermetically sealed container with twistable overcap

Claim 2

A hermetically sealed container comprising: a hollow body portion for containing a liquid; a neck portion at one end of said hollow body portion, defining a container access opening and unitary with the hollow body portion; a closure portion at the distal end of said neck portion and unitary therewith; said closure portion including a substantially planar end wall extending across said access opening, a removable cap means, and a frangible web unitary with said cap means and said end wall; an overcap covering said closure portion, rotatably mounted on said neck portion, and provided with an integral dispensing nozzle, said nozzle spaced from and communicating with said closure portion end wall; said closure portion end wall defining a container contents-dispensing aperture therein and being unitary with said neck portion; said removable cap means beig situated over said aperture; and said overcap being provided with retainer means mating with said removable cap means and adapted to break said frangible web when the overcap is rotated.

Claim 3

The container in accordance with claim 1 in which said neck portion is generally cylindrical, in which said overcap is mounted on said neck portion for rotation about the longitudinal axis of the neck portion, and in which said aperture and overlying cap means are radially spaced away from said longitudinal axis; whereby when said overcap is rotated, said cap means is moved away from said aperture so as to provide a free flow path for said liquid out of said hollow body portion and through said nozzle.

Claim 4

The container in accordance with claim 2 in which said neck portion is provided with an outwardly extending circumferential protuberance and in which said overcap is retained in place on said neck portion by said protuberance.

Claim 5

The container in accordance with claim 1 in which said cap means has a generally disc-like configuration with an upstanding fin adapted to mate with said overcap.

Claim 6

The container in accordance with claim 1 in which said neck portion is generally cylindrical and in which said end wall defines said container contents-dispensing aperture therein with a non-circular configuration, whereby when said overcap is rotated a predetermined amount, said cap means rotates together with said overcap about the longitudinal axis of said generally cylindrical neck portion to break said frangible web and exposed at least a portion of said aperture

Claim 7

The container in accordance with claim 5 in which said end wall defines a container contents-dispensing aperture therein having a generally oblong configuration.

Claim 8

The container in accordance with claim 6 in which said end wall defines a container contents-dispensing aperture therein having a generally elliptical configuration.

Claim 9

The container in accordance with claim 5 in which said retainer means of said overcap defines a cap receiving cage means extending outwardly from said end wall for permitting said removable cap means to move away from said end wall when said frangible web is broken so as to provide a free flow path for said liquid out of said hollow body portion and through said nozzle.

Claim 10

The container in accordance with claim 8 in which said cap receiving cage means includes at least one pair of spaced apart wall members.

Claim 11

The container in accordance with claim 1 in which said cap means has a generally cylindrical, disc-like configuration; in which said neck portion is generally cylindrical; in which said cap means is oriented on said end wall with the center of the cap means substantially coincident with the longitudinal axis of said neck portion; and in which said retainer means of said overcap defines a cap receiving cage means for permitting said cap means to move outwardly from said end wall after said frangible web has been broken so as to provide a free flow path for said liquid out of said hollow body portion and through said nozzle.

Claim 12

The container in accordance with claim 1 in which said overcap has outwardly projecting exterior members.

Claim 13

The container in accordance with claim 1 in which said neck portion has a generally cylindrical configuration and in which said neck portion has a circumferential snap-fit protuberance for engaging and retaining said overcap in a snap-fit interlock while permitting rotation of said overcap relative to said neck portion.

Claim 14

The container in accordance with claim 1 in which said cap means has a generally disc-like configuration; in which said neck portion is generally cylindrical; in which said cap means is located on said end wall with the center of said cap means displaced from the longitudinal axis of said cylindrical neck portion whereby said overcap can be rotated to break said frangible web and carry said cap away from said aperture on an arc of revolution around the longitudinal axis of said generally cylindrical neck portion so as to provide a free flow path for said liquid out of said hollow body portion and through said nozzle.

Claim 15

A hermetically sealed container comprising: a hollow body portion for containing a liquid; a generally cylindrical neck portion at one end of said hollow body portion, defining a container access opening and unitary with the hollow body portion; a closure portion at the distal end of said neck portion and unitary therewith; an overcap covering said closure portion, rotatably mounted on said neck portion, and provided with an integral dispensing nozzle; said closure portion including a substantially planar end wall extending across said access opening, a removable cap means, and a frangible web unitary with said cap means and said end wall; said end wall defining a container contents-dispensing aperture therein and being unitary with said neck portion; said removable cap means including a generally cylindrical disc-like cap with an outwardly projecting fin; said removable cap means being situated over said aperture on said end wall with the center of the disc-like cap substantially coincident with the longitudinal axis of said neck portion; and said overcap being provided with a cap receiving cage means for mating with said cap and fin to break said frangible web when the overcap is rotated; said cap receiving cage means permitting said cap and fin to move outwardly from said end wall after said frangible web has been broken so as to provide a free flow path for said liquid out of said hollow body portion and through said nozzle.

Claim 16

A hermetically sealed container comprising: a hollow body portion for containing a liquid; a generally cylindrical neck portion at one end of said hollow body portion, defining a container access opening and unitary with the hollow body portion; a closure portion at the distal end of said neck portion and unitary therewith; an overcap covering said closure portion, rotatably mounted on said neck portion, and provided with an integral dispensing nozzle; said closure portion including a substantially planar end wall extending across said access opening, a removable cap means, and a frangible web unitary with said cap means and said end wall; said end wall defining a container contents-dispensing aperture therein and being unitary with said neck portion; said removable cap means including a generally cylindrical disc-like cap with an outwardly projecting fin; said removable cap means being situated over said aperture on said end wall with the center of the disc-like cap substantially coincident with the longitudinal axis of said neck portion; and said overcap being provided with a cap receiving cage means for mating with said cap and fin to break said frangible web when the overcap is rotated; said cap receiving cage means permitting said cap and fin to move outwardly from said end wall after said frangible web has been broken so as to provide a free flow path for said liquid out of said hollow body portion and through said nozzle.
