Abstract: Bottle opening device, particularly for cutting the capsule covering the stopper of a bottle, comprising a shaft provided with a threaded portion and, above, with a widened portion that has a hole in it. The widened portion comprises two plates which are provided internally with mutually aligned openings for the transversal insertion of a stopper. The plates are spaced apart so as to define a space for accommodating a supporting body which is provided with at least one cutting element.

Abstract: A cutting device for removing the upper part of capsules covering the cork in bottles of wine and the like, including a body made of rigid plastics that is substantially shaped externally like a parallelepiped and substantially has the profile of a stylized uppercase U, the internal opposite faces of the wings of said U having two opposite and identical step-like recesses, on each whereof two raised portions or teeth are provided which support, in a recessed position with respect to the inner edge of the wings, a sharp metal cutting blade that is substantially curved in a semicircular shape so as to allow the mutually opposite and co-planar blades to form, therebetween, the space for insertion on the capsule that is anchored to the bottle neck, thinner regions being furthermore provided on the wings that support the laminae and being adapted to make the wings flexible, so as to allow to clamp them on the capsule and cut the upper part of the capsule by a rotation of the wings through approximately 180.degree.

Abstract: The corkscrew has a Teflon-coated worm and a body, which can be associated with the neck of a bottle and rotatably and slidably supports, in an upward region, the Teflon-coated worm, which is connected to an actuation butterfly. The corkscrew also has a guiding slider which slidably engages the body and defines a guiding hole which engages and axially positions the worth to position it axially.
