Device for ejecting a cork from a corkscrew and corkscrew provided with such an ejection device

A tubular cradle for ejecting a cork from a corkscrew having a body forming a housing and tubular passage and a spiral, the tubular cradle comprising:

• a stationary sleeve having a stationary sleeve upper end and a stationary sleeve lower end opposite said stationary sleeve upper end, wherein said stationary sleeve is comprised of a first stationary sleeve section having a first stationary sleeve section diameter at said stationary sleeve upper end, a second stationary sleeve section having a second stationary sleeve section diameter at said stationary sleeve lower end, and a stationary sleeve shoulder between said first stationary sleeve section and said second stationary sleeve section, and wherein said second stationary sleeve section diameter is greater than said first stationary sleeve section diameter, a sliding sleeve having a sliding sleeve upper end and a sliding sleeve lower end opposite said sliding sleeve upper end, wherein said sliding sleeve is comprised of a first sliding sleeve section having a first sliding sleeve section diameter at said sliding sleeve upper end, a second sliding sleeve section having a second sliding sleeve section diameter at said sliding sleeve lower end, and a sliding sleeve shoulder between said first sliding sleeve section and said second sliding sleeve section, and wherein said second sliding sleeve section diameter is greater than said first sliding sleeve section diameter;
• and a means to exert force on the cork positioned at said sliding sleeve upper end, wherein said sliding sleeve has a nested position within said stationary sleeve, said first sliding sleeve section being housed in said first stationary sleeve section, said second sliding sleeve section being housed in said second stationary sleeve section, wherein said sliding sleeve has a translated position partially within said stationary sleeve, said first sliding sleeve section being housed in said second stationary sleeve section, said second sliding sleeve section extending outward from said a second stationary sleeve section, and wherein said sliding sleeve is moveable from said nested position to said translated position and back to said nest position so as to eject a cork from said corkscrew;
• and a membrane seal having a central orifice and being positioned over said sliding sleeve upper end, wherein the membrane seal further comprises an annular stop having an annular stop height centered on said center orifice, said annular stop extending downward from said sliding sleeve upper end so as to form said means to exert force on the cork.
