Abstract
Corkscrew comprising a handle and a helically-shaped screw part, where the helically-shaped part (2) being formed is extended spirally, having its smallest diameter near the handle, and being flat with the outside aligning with a conical envelope surface, the terminating end (3) remote from the handle also being flat but being arranged radially and perpendicularly to the center axis of the corkscrew, the screw part having decreasing diameter toward the end (3) from the point where the screw part is twisted from a position aligned with the conical surface, to a position perpendicular to the center axis, and a center peg (1) being secured to the handle, concentric to the screw part (2).
Claims5
A corkscrew comprising a handle and a helically-shaped flat screw part with the outside aligning with a conical envelope surface with its smallest diameter near the handle, the terminating end remote from the handle being arranged radially and perpendicular to the center axis of the corkscrew, the screw part having a decreasing diameter toward the end from the point where the screw part is twisted from a position aligned with a conical surface to a position perpendicular to the center axis, and a center peg secured to the handle, concentric to and spaced from the screw part outside said handle and extending at least to the end of the screw part.
A corkscrew comprising a handle and a helically shaped screw part, characterized in that the helically shaped part is formed as an extended conical spiral having its smallest diameter near the handle, and having a center peg secured to the handle, concentric to and spaced from the screw part throughout its entire length outside said handle and extending at least to the end of the screw part.
Corkscrew comprising a handle and a helically-shaped screw part, characterized in the helically-shaped part (2) being formed as an extended spiral having its smallest diameter near the handle, and being flat with the outside aligning with a conical envelope surface, the terminating end (3) remote from the handle also being flat but being arranged radially and perpendicularly to the center axis of the corkscrew, the screw part having decreasing diameter towards the end (3) from the point where the screw part is twisted from a position aligned with the conical surface, to a position perpendicular to the center axis, and a center peg (1) being secured to the handle, concentric to the screw part (2).
