Abstract
Abstract An end closure for a shake and pour container is disclosed having a cover which is mounted on a canister type container. The cover has a rotor rotatably mounted on the cover. The cover has a break-away, hinged lid formed therein with the lid having a tab extending out from the lid beyond the hinge line. Upon applying a downward force on the lid, the lid may be broken away from the cover and rotated downwardly into the container along the hinge line thus opening the container. As the lid rotates down, the tab is also broken away from the cover and rotates upwardly above the level cover so as to be engaged by the rotor thereby to hold the lid in its full open position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
183 words
An end closure for a container comprising a cover mountable on end of said container, said cover having a generally planar center face, a rotor having an opening therethrough rotatably mounted on said cover, and a break-open lid comprising a portion of said cover center face and defined within said cover by at least one frangible line and by hinge means, said lid having an integral tab portion generally within the plane of said lid and extending from said lid beyond said hinge means, said lid upon breaking said frangible line being movable from a closed position in which said lid is generally within the plane of said cover center to a face open position in which said lid is pivoted downwardly about said hinge means such that at least a portion of said lid extends downwardly into said container through the opening created by breaking of said frangible line and such that said tab portion extends at least partially above said cover center face with said tab portion cooperating with said rotor so as to hold said lid in its open position.
Claim 2
Dependent Claim
183 words
An end closure for a container comprising a cover mountable on end of said container, said cover having a generally planar center face, a rotor having an opening therethrough rotatably mounted on said cover, and a break-open lid comprising a portion of said cover center face and defined within said cover by at least one frangible line and by hinge means, said lid having an integral tab portion generally within the plane of said lid and extending from said lid beyond said hinge means, said lid upon breaking said frangible line being movable from a closed position in which said lid is generally within the plane of said cover center to a face open position in which said lid is pivoted downwardly about said hinge means such that at least a portion of said lid extends downwardly into said container through the opening created by breaking of said frangible line and such that said tab portion extends at least partially above said cover center face with said tab portion cooperating with said rotor so as to hold said lid in its open position.
Claim 3
Dependent Claim
17 words
The end closure of claim 1 further comprising means for rotatably mounting said rotor on said cover.
Claim 4
Dependent Claim
46 words
The end closure of claim 2 wherein said rotor has a bottom face, and wherein said means for rotatably mounting said rotor on said cover comprises a stud on the bottom of said rotor and a center opening in said cover for rotatably receiving said stud.
Claim 5
Dependent Claim
16 words
The end closure of claim 3 wherein said stud snap fits into said cover center opening.
Claim 6
Dependent Claim
110 words
The end closure of claim 1 wherein said at least one frangible line defining said lid comprises a curvilinear line generally concentric with said cover, and wherein said hinge means comprises a chord-like straight hinge line, said opening in said rotor having a curvilinear outer edge and a chord-like straight edge with the curvilinear and straight edges of said opening in said rotor being generally coextensive with the corresponding curvilinear frangible line and straight hinge line of said lid such that with said lid in its open position, said tab cooperates with said straight chord-like edge of said rotor opening thereby to positively hold said lid in its open position.
Claim 7
Dependent Claim
68 words
The end closure of claim 1 wherein said hinge means comprises a hinge line in said cover, and wherein with said lid in its closed position said lid is substantially within the plane of said cover center face, being defined in said cover by one or more frangible lines in said cover extending from said hinge line on the side of said hinge line opposite from said lid.
