Abstract: The present invention refers to a snap-type corkscrew, i.e. a corkscrew that snaps open when it has to be used. A corkscrew according to the invention comprises a handle (1), a screw (16) that is pivotally associated to said handle (1), and an arm (14) that is in turn pivotally associated to said handle (1), said screw (16) and said arm (14) being movable between a first resting position thereof, in which the screw (16) and the arm (14) are at least partially lying upon each other, and a second operative position thereof. The inventive corkscrew is characterized in that it comprises actuation means (18) adapted to impart a movement to the screw (16) and the arm (14) causing them to displace from the resting position towards the operative or working position thereof, and in that it comprises retaining means (20, 220, 320, 420) adapted to positively retain the arm (14) or the screw (16) in their folded position against said handle (1) of the corkscrew.

Abstract: A corkscrew includes a handgrip (1), a screw (2) associated to the handgrip (1) by means of a first pivoting connection (3), and an arm (4, 4?) comprising first abutting members (5, 5?) and associated to the handgrip (1) by means of a second connection (21) that enables the arm (4, 4?) to rotate, with the arm (4, 4?) being further capable of performing a second movement relative to the handgrip (1). The inventive corkscrew is characterized in that it comprises elastic means (10) that are adapted to affect at least the second movement of the arm (4, 4?) so as to assist in pulling out a cork (7) from a bottle (6).
