Cork extractor

A cork extractor device for use with a removable compressed fluid container having a substantially cylindrical body, an outlet tube, and a self-contained valve actuated by depressing said outlet tube, therein comprising:

• an elongated body having a containing section, a sliding section, and a positioning section;
• said containing section having a substantially circular cross section having a length, an upper end being open, an inner cavity adapted to removably receive said container, and a lower end comprising a needle assembly extending across substantially said cross section of said lower end;
• said needle assembly comprising a fluid channel having an inlet cavity and an outlet;
• said inlet cavity adapted to a partially receive the length of said outlet tube, said fluid channel having a diameter smaller than an inner diameter of said outlet tube, wherein when said outlet tube is positioned in said inlet cavity and said container is forced downward, said outlet tube abuts against said fluid channel releasing fluid into said fluid channel;
• and
• a needle having a hollow longitudinal passageway being operatively connected to said fluid channel outlet and of sufficient length to axially traverse downstream of said fluid channel to receive fluid therefrom and pass said fluid through the length of a cork into a bottle when said extractor is in a compressed state.
• said sliding section comprising a first portion and a second portion;
• and
• said first portion is disposed adjacent to said lower end of said containing section, having an open interior and adapted to slidably engage with said containing section;
• said second portion terminating at a second end comprising a centrally disposed needle passageway of sufficient diameter to spatially relate from said needle and further comprising a needle inlet extending downward to terminate at a needle outlet at said second end;
• said needle inlet further comprising a needle inlet support extending substantially across an entire cross-section of said sliding section;
• and said needle outlet having a diameter less than the diameter of said cork to create an abutment against said cork;
• said positioning section having a substantially circular cross section and being rotationally engaged to said sliding section, comprising an interior section, an exterior section, and a tubular sleeve;
• said interior section disposed within said second portion of said sliding section, wherein said interior section extends substantially from said second end of said sliding section towards said needle inlet support defining an interior inner cavity containing said needle passageway and said tubular sleeve therein;
• said exterior section comprising a lip disposed adjacent to said second end of said sliding section and extending substantially linearly downward defining an exterior inner cavity dimensioned to receive the circumference of a bottleneck within and extend at least partially downward over said bottleneck to coaxially position said needle over said cork;
• said tubular sleeve is coaxially disposed about said needle passageway, wherein said tubular sleeve is dimensioned to extend longitudinally along said needle passageway at least to said needle outlet;
• said tubular sleeve having at least one helical groove extending longitudinally around the exterior length of said tubular body;
• and
• said interior inner cavity having a protuberance corresponding to said at least one helical groove to rotationally drive said tubular sleeve in an axial direction when said positioning section is rotated;
• wherein, when said exterior inner cavity of said positioning section engages said bottleneck and a downward force is applied, said containing section slides along the length of said first section of said sliding section towards said cork, said needle is driven through said cork, and when said container is subsequently forced downward, said outlet tube depresses to release said fluid into said bottle increasing the pressure therein and ejecting said cork upon said needle;
• wherein, when exterior section of said positioning section is rotated, said tubular sleeve traverses downward along said needle abutting against said removed cork to facilitate removal of said cork from said needle.

A method for withdrawing a cork from a bottleneck of a bottle with a cork extractor device having a containing section, a sliding section, and a positioning section, for use with a removable compressed fluid container having a substantially cylindrical body, an outlet tube, and a self-contained valve actuated by depressing said outlet tube, therein comprising steps:

• positioning said compressed fluid container within said containing section;
• positioning said positioning section over said bottleneck extractor device;
• applying a downward force to slidably engage said containing section along at least part of the length of said sliding section towards said cork and against a resistance means housed therein and drive said needle through said cork;
• and
• applying a downward force to said container causing said outlet tube to abut against said containing section releasing fluid through said needle into said bottle, thereby increasing the pressure therein and ejecting said cork upon said needle.
