Abstract: A device for the controlled removal and re-insertion of the cork used with the conventional champagne bottle. The device has a first member having a cavity which is sized and shaped to straddle the neck of the bottle, with a plastic insert to specifically fit the circumferential rib which the conventional champagne bottle has near the spout. A second member contains annular ridges to slide onto and grip the head of the cork. A single handle utilizes a rack gear mechanism to move the two members apart, linearly and under leverage, so that the cork can be removed and re-inserted with ease.

Abstract: A device for the controlled removal and re-insertion of the cork used with the conventional champagne bottle. The device has a first member having a cavity which is sized and shaped to straddle the neck of the bottle, and specifically the circumferential rib which the conventional champagne bottle has near the spout. A second member is sized and shaped to slide onto the head of the cork. Various types of handles, linkages and gears are shown to move the two members apart, linearly, and under leverage, so that the cork can be removed and re-inserted with ease.

Abstract: Tubular telescoping members have interrupted circumferential lugs which engage through relative axial movement followed by relative turning movement of the members. A releasable locking device prevents reverse relative turning movement of the members and comprises a plurality of threaded lock elements engaging internally threaded openings in an outer tubular member near its terminal shoulder. Each lock element is installed from the inside of the outer member, and has a portion accessible exteriorly of the outer member. Each lock element has a circular flange which projects beyond the terminal shoulder and into a detent provided on an external annular shoulder on the inner member. The circular flange is interrupted at one location by a flat face which is flush with the terminal shoulder when the lock element is turned one-half revolution.
