Abstract
A sealing and dispensing cap for a carbonated drink container permits the container to be inverted with the cap disposed in a closed position to trap carbonating gases, whereupon the cap is disposed in an open position to dispense the carbonated drink. This cap prevents carbonated drink from going "flat" by preventing the escape of carbonating gases during drink dispensation.

A sealing and dispensing cap for a container comprising
- a cap body having a cap sealing plate extending laterally across substantially a mid-portion of said cap body thereby dividing said cap body into an upper cap body portion and a lower cap body portion, said upper cap body portion including dispensing means and said lower cap body portion including container attachment means, said cap sealing plate having a sealing plate aperture formed therein communicating with an inside portion of said container, said upper cap body portion being formed having a top wall that includes a nipple integrally formed with the top wall of said upper cap body portion,
- said dispensing means including a lever arm extending laterally through a slot formed in said upper cap body portion between the lower end of said dispensing means and said cap sealing plate, said lever arm projecting to opposing sides of said upper cap body portion, said lever arm having a lever arm opening formed therein, said lever arm being slidably moveable laterally for selective vertical alignment and misalignment of said lever arm opening and said sealing plate aperture,
- said lever arm comprising a substantially flat extended member having a first push/pull tab orthogonally and integrally formed at a first end of said lever arm and a second push/pull tab orthogonally and integrally formed at a second end of said lever arm, said lever arm opening being disposed between the respective first and second ends of said lever arm,
