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). The projection engages a stop (74) so that further reverse rotation returns the barrel to the initial position.

A corkscrew comprising a housing having means for locating the housing over the mouth of a corked bottle, a screw member having a handle outside the housing and a screw within the housing, whereby rotation of the member in a first direction drives the screw into the cork in the bottle and the member axially into the housing, and first limiting means limiting said axial movement whereby continued rotation of the member in said first direction drives the cork into the housing and out of the bottle, wherein a barrel is screw-engaged in the housing and the limiting means is between the barrel and the member so that the cork is driven into the housing by axial movement of the barrel relative to the housing, means is provided in the housing for engaging the end of the cork, whereby rotation of the member in a second direction, opposite to the first direction, releases, or almost releases, the screw from the cork with axial movement of the member relative to the barrel and the housing, and second limiting means between the barrel and the member whereby continued rotation of the member in said second direction effects return axial movement of the barrel relative to the housing.
