Abstract: A cork remover for removing corks from bottles, particularly bottles having substantial internal gas pressure, such as champagne bottles, includes a tapered, generally tubular part, which is placed over the shoulder of the bottle. A hollow, threaded, tubular member is secured to the tapered part and is threaded to a tubular sleeve which has ports on opposite sides of its sidewall. Sharpened pins are movable through the ports to puncture and hold the cork. In one embodiment, the pins are threaded to the sleeve and are turned into the cork by means of handles secured to the pins. In another embodiment, the pins are replaced with C-shaped members having abrasive surfaces which are pressed into the sides of the cork, enabling it to be turned by use of the handles. Further embodiments utilize an L-shaped handle pivotally secured to the sleeve to force one or both pins into the corks. The handle can then be turned to break the cork loose and enable it to be removed.

Abstract: A corkscrew assembly capable of use with a lever-type cork extractor and comprising a bearing-rivet combination fixedly attached to a helical component forming a corkscrew head. A spacer is mounted on the bearing of the corkscrew head and both the spacer and the corkscrew head are disposed in the cavity of a cup-shaped nut forming the corkscrew assembly of the present invention. The corkscrew assembly is detachably mounted to a component of a cork extractor body and thus removably coupled to a cork extractor. The mounted corkscrew is caused to simultaneously move longitudinally and rotate by the cork extractor body. Due to the presence of the spacer, the corkscrew assembly rotates in a smooth and unhampered fashion about a relatively fixed axis of rotation. The cup-shaped nut protects the bearing from debris and liquids. The corkscrew assembly or any portion thereof can be replaced when damaged.

Abstract: An apparatus for removing a cork from a bottle in which an anchor is embedded in the cork and a cork-pulling sleeve is provided for engaging the anchor for removal of the cork. The cork-pulling sleeve includes inner threads that mate with external threads on the neck of the bottle, and rotation of the cork-pulling sleeve in relation to the bottle extracts the cork.

Abstract: The invention refers to the attachment for extraction of cork and similar bottle stoppers enabling extraction of cork stopper without application of additional tool and/or special opener, designed for the respective purpose. The attachment referred to in this invention consists of the basic threaded body (2) with a tape shaped pull cord (5) coming out of the upper part of the attachment. The attachment referred to in this invention may also be built in the body (1) as a screw (2′) with a preliminarily inserted washer (3) provided with a groove (4) that serves as a channel for the pull cord (5′). In the second example the attachment in the body (1′) is shaped as a screw (2′) with recess (7) with an edge (8) at the bottom, while the pull cord (5′) is attached to the bayonet plug (9).

Abstract: A corkscrew includes a body having first and second elongate handgrips connected together for gripping the neck of a wine bottle, a central helical screw between the handgrips to remove a cork from bottle, and a turning knob atop the body and co-axially supporting the screw. The first handgrip has at its upper end a downwardly-opening cavity. The second handgrip is pivotably connected at its upper end to the first handgrip by a connector inserted from below into the cavity. The connector incorporates a hinge pin that passes through the connector and the upper end of the second handgrip. The pin is confined by a peripheral wall of the cavity extending around the connector.

Abstract: A multipurpose corckscrew has a main body, a helical screw connected with the main body and introducible into a cork to be removed, an arm provided with an end tab and connected with the main body, a guide connecting the arm with the main body so that the arm is displaceable on the guide between a rear position and a forward position, means keeping the arm in the forward position, and elastic means pushing the arm toward the rear position.

Abstract: A spiral for a corkscrew has a spiral member with a pointed end for introduction into a cork of a bottle and also, with a part which is located opposite to the pointed introduction end and having an opposite end, a ball bearing connected with the opposite end of the spiral member, so that during introduction of the spiral member into a cork and removal of the screw member from the cork the spiral member is rotated relative to a rest of the corkscrew, and an element for connecting the ball bearing with the opposite end of the part of the screw member.

Abstract: A force minimizing corkscrew which comprises a guiding holder, a cork engaging means which is inserted into said guiding holder, and a force generating member which is attached to said cork engaging means, after first placing upper and lower bearings between the elements.

Abstract: A multipurpose folding tool, for use by picnickers and travelers, including a corkscrew, a crown cap remover, and a can opener, as well as a small fork and a small butter knife. Both the corkscrew and a brace for use together with it fit close to the handles of the tool when the tool is in a compact, folded configuration. A spring in one handle keeps the corkscrew safely folded when not in use, and a spring on the brace keeps it in a desired position relative to the handles. The tool also includes folding pliers and may include folding screwdrivers, knife blades, and scissors.

Abstract: An apparatus for removing a cork from a bottle in which an anchor is embedded in the cork and a cork-pulling handle is provided for engaging the anchor for removal of the cork. The cork-pulling handle can be connected to the anchor by any of several means, and can be stored with the bottle as an integral part of the bottle/capsule/label package or provided separately.
