Abstract: The corkscrew comprises a housing (12) in which is screw-engaged a barrel (14). The barrel has an internal screw thread (56), of opposite hand to its outer thread (52), engaged with the housing, and a drive member (16), carrying a screw (24), and a handle (22) has a projection (58) engaged in the internal screw thread. The bottom of the barrel has a cork engaging portion (66) for gripping the top of a cork when the housing is seated on the neck of a bottle with the screw piercing the cork. The handle (22) is rotatable in one direction to drive the screw into the cork. The projection (58) moves down the internal thread (56) and engages a stop (72) so that continued rotation raises the barrel with the drive member to draw the cork into the housing. On reverse rotation of the handle, the projection moves up the internal thread to withdraw the screw such that the cork is pushed out and released from the screw by the cork engaging portion ( 66).
