Dispensing stopper for a bottle

A dispensing stopper for a bottle, comprising:

• a stopper base adapted to be mounted on the mouth of a bottle;
• a unitary seal of elastomer mounted on said base, said seal including a fixed section fixed to said base, a movable gasket section movable toward and away from said stopper base and away and toward a sealing surface about the mouth on a bottle to which said base is mounted, and a thin, web of resilient material interconnecting and sealing said fixed section and said movable gasket section;
• an actuator attachment section affixed to said movable gasket section;
• said base including a radially inward directed circular flange and said actuator section including a radially outward directed circular edge, and said seal being a unitary ring of resilient elastomer with said fixed section having a radially outward opening groove sealingly receiving said flange and said gasket section having a radially inward opening groove sealingly receiving said edge;
• and
• a lever pivoted to said base and to said actuator attachment section at spaced locations;
• whereby application of a pivoting force to said lever will move said gasket section toward said fixed section to move said gasket section away from the mouth of a bottle on which said base is mounted and the absence of said force will allow tie resiliency of said web to return said gasket section toward the mouth of a bottle on which said base is mounted.

• a unitary seal of elastomer mounted on said base, said seal including a fixed section fixed to said base, a movable gasket section movable toward and away from said stopper base and away from said stopper base and away and toward a sealing surface about the mouth on a bottle to which the base is mounted and adapted to seal about the mouth of a bottle, and a thin, web of resilient material interconnecting and sealing said fixed section and said movable gasket section;
• an actuator attachment section affixed to said movable gasket section;
• a lever pivoted to said base and to said actuator attachment section at spaced locations;
• and
• a cap secured to said base, one of said cap and said base including spaced saddles for receiving a pivot located intermediate said ends of said lever and the other of said cap and said base including spaced projections aligned with and directed toward said saddles for holding, said pivot in said saddles;
• whereby application of a pivoting force to said lever will move said gasket section toward said fixed section to move said gasket section away from the mouth of a bottle on which said base is mounted and the absence of said force will allow the resiliency of said web to return said gasket section toward the mouth of a bottle on which said base is mounted.

• an actuator attachment section affixed to said movable gasket section;
• a lever pivoted to said base and to said actuator attachment section at spaced locations;
• a cap on said base;
• and
• a funnel-like structure formed in said cap and extending to an opposite side of said stopper;
• whereby application of a pivoting force to said lever will move said gasket section toward said fixed section to move said gasket section away from the mouth of a bottle on which said base is mounted and the absence of said force will allow the resiliency of said web to return said gasket section toward the mouth of a bottle on which said base is mounted.
