Abstract
A closure cover for sealing a liquid container including a body having an orifice for dispensing the liquid in the container, and a rotating disk pivotally attached to the body and providing an effective seal for the dispensing orifice. The effective seal is created by a downward force upon a sealing gasket, such force being the result of the rotation of the disk member containing a ramp which is moved under a cam on the body.
Claims38
A closure device for sealing a container, comprising:
- a body having a dispensing orifice;
- a rotating member pivotally attached to said body and having sealing means for sealing said orifice such that said orifice is in a closed condition, said rotating member allowing flow through said dispensing orifice when said orifice is in an open condition;
- and
- pressing means responsive to the rotation of said rotating member for pressing said sealing means at said orifice to ensure proper seal of said orifice, said pressing means applying a downward force to a top surface of said rotating member along a portion of a perimeter of said rotating member that is adjacent said dispensing orifice.

A closure device for sealing a container, comprising:
- a body having a dispensing orifice;
- a rotating member pivotally attached to said body and having sealing means for sealing said orifice such that said orifice is in a closed condition, said rotating member allowing flow through said dispensing orifice when said orifice is in an open condition;
- a ramp attached to said rotating member, said ramp having a planar surface and an inclined surface, said inclined surface is inclined relative to and is adjacent to said planar surface;
- and
- a cam attached to said body, said cam riding along said inclined surface when said rotating member is rotated to apply a downward force to said rotating member to seal said orifice, said cam resting on said planar surface when said orifice is in the closed condition.

A closure device for sealing a container, comprising:
- a body having a dispensing orifice;
- a rotating member pivotally attached to said body and having sealing means for sealing said orifice such that said orifice is in a closed condition, said rotating member allowing flow through said dispensing orifice when said orifice is in an open condition;
- a ramp attached to said rotating member, said ramp being positioned on and extending upwards from a top surface of said rotating member;
- and
- a cam attached to said body and extending inward from the perimeter of said body, wherein said ramp engages said cam and thereby presses said sealing means into said orifice when said orifice is in the closed condition.
2 more elements
A closure device for sealing a container, comprising:
- a body having a dispensing orifice;
- a rotating member pivotally attached to said body;
- a flange attached to and extending downward from said rotating member, said flange having a lower surface that protrudes into said orifice when said orifice is in a closed condition, said flange having an annular channel disposed on a side surface of said flange;
- a gasket disposed in said channel and extending around said flange, said gasket engaging a top surface of said body adjacent said dispensing orifice when said orifice is in the closed condition such that said dispensing orifice is properly sealed;
- and
- said rotating member having a cutout portion disposed along its periphery, and when said orifice is in an open condition, said cutout portion is disposed directly over said dispensing orifice and thereby allows direct access to said dispensing orifice.

A closure device for sealing a container, comprising:
- a body having a dispensing orifice, an upstanding lip with a longitudinal aperture disposed therein, and a body top surface;
- a rotating member pivotally attached to said body;
- a flange attached to and extending downward from said rotating member, said flange having a lower surface that protrudes into said orifice when said orifice is in a closed condition, said flange having an annular channel disposed on a side surface of said flange;
- a gasket disposed in said channel and extending around said flange, said gasket engaging said body top surface adjacent said dispensing orifice when said orifice is in the closed condition such that said dispensing orifice is properly sealed;
- and
- a lever attached to said rotating member for rotating said member, said lever extending through said aperture.
3 more elements
A closure device for sealing a container, comprising:
- a body having a dispensing orifice and a body top surface, said body top surface having a depression;
- a rotating member pivotally attached to said body;
- a flange attached to and extending downward from said rotating member, said flange having a lower surface that protrudes into said orifice when said orifice is in a closed condition, said flange having an annular channel disposed on a side surface of said flange, said lower surface of said flange extending into said depression when said orifice is in an open condition;
- and
- a gasket disposed in said channel and extending around said flange, said gasket engaging said body top surface adjacent said dispensing orifice when said orifice is in the closed condition such that the dispensing orifice is properly sealed.
