Abstract
A container closure apparatus having a base for attachment to the container. The base has an opening for passing the contents of the container. A lever is hinged to the base, such that an upward force on a rearward portion of the lever causes a frontward portion of the lever to depress the container material creating an opening directly beneath the opening in the base. A portion of the lever is adapted to seal the opening in the base, and thus the container, when the lever is in its closed position.
Claims5
A closure apparatus comprising:
- a base comprising a post, said base further comprising a wall that defines an opening;
- a lever rotatably secured to said base such that an upward force on a rearward portion of said lever is adapted to cause said lever to rotate about an axis thereby disengaging a frontward portion of said lever from said wall of said base;
- and
- a cover rotatably connected to said base such that said cover has an axis of rotation approximately perpendicular to said axis of rotation of said lever, said cover comprising an annular structure extending around said post;
- wherein said annular structure is adapted to detach from said cover when said cover is rotated away from said base such that said annular structure remains on said post.

A container comprising:
- a substantially rectangular surface;
- and
- a closure apparatus secured to said substantially rectangular surface near an edge thereof, said closure apparatus comprising:
- a base comprising a post, the base further comprising a wall that defines an opening;
- a lever rotatably secured to said base such that an upward force on a rearward portion of the lever is adapted to cause the lever to rotate about an axis thereby disengaging a frontward portion of the lever from the wall of the base;
- and
- a cover rotatably connected to the base such that the cover has an axis of rotation approximately perpendicular to the axis of rotation of the lever, the cover comprising an annular structure extending around the post;
- wherein the annular structure is adapted to detach from said cover when said cover is rotated away from said base such that the annular structure remains on said post.
