  • Patent number: 4296653
    Abstract: A method and a device for removing corks from vessels. The device comprises a pair of knives and a holder for the knives, which holder fixes the position of the knife-edges relative to each other and with a spacing between the knife-edges, which spacing is smaller than the diameter of the cork to be removed from a vessel measured immediately above the position on the cork where it is intended to be gripped between the knives. By use of the device the cork is removed by moving the vessel with the attached cork towards the knives at a level suitable to position the portion of the cork that extends above the vessel between the knife-edges and moving the vessel away from the knives.
