Guided cork extractor

Abstract

Examples relate to a guided cork extractor for removing corks from beverage containers includes a main body with legs that grip a bottle neck and center a corkscrew over the cork. An insert within the mam body engages the corkscrew to prevent vertical slippage when rotated below a threshold resistance, allowing the corkscrew to penetrate the cork without requiring substantial downward force. When resistance exceeds the threshold, the corkscrew rotates freely to extract the cork upward. The device includes seal cutters for removing bottle covers and flexible gripping members that allow the main body to grip the cork during corkscrew removal. The semi-flexible construction adapts to variations in bottle and cork dimensions.

Description

Docket No. 6826.001 WO1GUIDED CORK EXTRACTOR CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Application No. 63 / 730,970, filed on December 12, 2024, the disclosure of which is incorporated herein in its entirety by this reference as if explicitly set forth.TECHNICAL FIELD

[0002] The present disclosure relates generally to a cork extractor and more particularly (but not exclusively to) to a guided cork extractor configured to remove a cork from a beverage container.BACKGROUND

[0003] Users face challenges when removing corks from wme bottles. Existing corkscrews and wme openers can present challenge during use. For example, users may struggle to center the screw when first penetrating the cork, often requiring multiple attempts and resulting in damaged corks, or portions of the cork getting stuck within a bottle. An off-centered or angled screw can encounter resistance when hitting an interior wall of a bottle, and require repositioning, which may cause further damage to the cork. Traditional corkscrews can be difficult to use, as users must simultaneously apply downward pressure to center and drive the corkscrew into the cork while rotating the handle, which is mechanically challenging due to the corkscrew's long axis.

[0004] Conventional wine opening tools demand frequent adjustments in hand placement during use, resulting in a cumbersome operation. Lever-style openers, for instance, present challenges with initial alignment, tend to slide away from the bottle rim when imprecisely placed, and often necessitate two-handed operation to generate sufficient force.BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

[0032] While a number of example embodiments are shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions will now occur to those skilled in the art. It should be understood that various alternatives to the examples described herein may be employed in practicing the disclosure.Docket No. 6826.001 WO1

[0033] Some examples relate to a guided cork extraction device. Various aspects of the disclosures described herein may be applied to any of the particular applications set forth below or for any other type of beverage containers. The various examples may be applied as a standalone system or method, or as part of a system that may extract corks or other coverings from containers. It should be understood that different aspects of the disclosure can be appreciated individually, collectively, or in combination with each other.

[0034] Wine is among the oldest and most well-established global industries. Over time, practices and delivery methods have become standardized. Today, a 750ml corked wine bottle is the most common method of delivering wine. Since the adoption of this standard from Europe in the United States in the 1970s, there has been little variation in the methods and devices used to open corked bottles of wine,

[0035] Even watching experienced restaurant workers, sommeliers, and wine pourers, there is little ease presented in the process of removing the cork from a bottle of wine. Common corkscrews and wine openers have users fumbling to center the screw upon penetrating the cork, resulting in multiple tries and frayed corks. An off-centered or angled screw can be stopped by the interior of a glass bottle, requiring repositioning. More advanced wine openers require pressured gas or electricity, making them expensive and unreliable.

[0036] Simply put, there is yet to exist an easily portable and reliable cork removal device for wme bottles that answers the practical needs of users. These needs include centering the screw as it enters the cork, applying downward pressure to the corkscrew at the same time as rotating a handle, having the cutter in a practical position for aluminum or wax seal removal, gripping the cork during screw removal, and gripping the bottle concurrently with the device.

[0037] Popular wme openers further require repositioning of the hands over each cycle of use to achieve the needs they can, resulting in an awkward experience for the user. This challenge is apparent for several reasons.

[0038] A static device that drives a corkscrew into a cork will always be mechanically hindered by the process of removing the cork: the downward- driving mechanism inherently contradicts upward motion because it must oppose the screw to move it downward. This forces a user to apply the downward force necessary to drive the screw into the cork at the same time it is centered on the cork, and the long axis of a corkscrew makes this inherently challenging.Docket No. 6826.001 WO1

[0039] Devices that use arms or levers to lift a cork out of a bottle run into the challenge of awkward setup and positioning of the parts needed, resulting in slipping off the lips of bottles when not positioned perfectly, or requiring multiple hands to gain enough leverage to lift the cork. Additionally, these designs still require multiple unnatural placements of the hands over each cycle of use.

[0040] On the global market, there exists an opening to resolve these needs in one simple to use, easily manufactured product. From winemakers to everyday enthusiasts, there is no need to fumble or struggle when removing a cork and no need to complicate a design. A simple, novel application of a modular mechanism, combined with modern manufacturing techniques, can create a simple, novel, inexpensive solution that can be used without frustration or upkeep. That way, users can simply focus on enjoying their wine, company, and creating meaningful memories,

[0041] The described examples address these challenges through a device that includes a main body, and a corkscrew configured to move relative to the main body. The main body may include a central portion and one or more legs extending from the central portion. The legs can wrap around a neck of a beverage container. An interior region may be provided between the legs. The legs may flex to accommodate variations in bottle neck dimensions.

[0042] The central portion of the main body can include a passageway through which the corkscrew passes. An insert or internal feature within the main body may engage with the corkscrew. In some examples, the insert includes a tooth element and a biasing mechanism. The biasing mechanism may be a spring that exerts lateral force on the tooth element. The tooth element can fit between coils of the corkscrew helix. In some examples, the insert may include internal threaded or helical features. The internal features can be complementary to the shape of the corkscrew. The internal features may include protruding portions that fit between turns of the corkscrew. The insert may be formed from a semi-rigid or elastomeric material. An insert may prevent the corkscrew from sliding vertically without rotation. An insert may also allow a rotational force exerted on the corkscrew to be sufficient to drive an upwards or downwards motion of the corkscrew without requiring the application of substantial upwards or downwards force.

[0043] When a user rotates the corkscrew in a first direction, the corkscrew moves downward into the cork. The first direction may be a clockwise or counterclockwise direction. The insertDocket No. 6826.001 WO1engages the corkscrew so that rotational force naturally causes downward motion. A user may not need to apply significant downward force. The corkscrew can penetrate into the cork through rotation alone. This may allow for more precise positioning of the corkscrew within the cork.

[0044] The corkscrew continues to move downward until a handle of the corkscrew contacts an upper surface of the main body. At this point, the corkscrew cannot descend further. The resistance experienced by the corkscrew may exceed a threshold value. The insert can allow the corkscrew to rotate without moving vertically when resistance exceeds this threshold. As the corkscrew continues to rotate in the first direction without vertical movement, upward force is applied to the cork. The cork may be pulled out of the beverage container.

[0045] The main body may include lip features on the legs. These lip features can rest on top of the beverage container. The lip features may help position the mam body relative to the beverage container. This positioning can center the corkscrew over the cork. In some examples, cutter features may be provided on or near the lip features. The cutters can cut through seals or coverings on the beverage container.

[0046] The device may include gripping mechanisms configured to engage the cork after extraction. The gripping mechanisms can be provided on flexible members that move relative to the main body. In some examples, a user may squeeze the flexible members together. This causes gripping features to be driven into sides of the cork. The cork may be prevented from rotating. The user can then rotate the corkscrew in a second direction opposite the first direction. The corkscrew withdraws from the cork while the cork remains gripped.

[0047] The corkscrew may include a handle at a proximal end. In some examples, the handle is a knob configured for twisting. In other examples, the handle may be a crank with a grip. The grip of the crank can revolve around a longitudinal axis of the corkscrew at a distance from that axis. This configuration may provide increased torque, making it easier to drive the corkscrew into the cork and extract the cork from the bottle.

[0048] The main body may be formed from plastic, elastomeric materials, wood, wire, metal, composite materials, or combinations thereof. The materials can provide some flexibility to accommodate different bottle sizes. The components may be formed as a single integral piece or assembled from multiple pieces.Docket No. 6826.001 WO1

[0049] The described examples may provide improved ease of use compared to traditional corkscrews. The automatic centering and downward driving of the corkscrew can reduce cork damage. The extraction phase may allow smooth removal without excessive force.

[0050] FIG. 1A shows a guided cork extractor 100, according to some examples. A cork extractor 100 may include a main body 110. A corkscrew helix 120 may pass through the main body. The corkscrew helix may include a handle 125 at a proximal end of the corkscrew helix. An insert 130 may fit within the main body and may be configured to interface with the corkscrew helix.

[0051] A main body 110 of the cork extractor 100 may include one or more legs 112a, 112b that may extend from a central portion 111 of the main body. An interior region 113 may be provided between the legs 112a, 112b. The central portion 111 of the main body may include a passageway through which the corkscrew helix 120 may pass. The passageway may be oriented along a longitudinal axis of the main body. The longitudinal axis of the main body may be parallel to or collinear with a longitudinal axis of the corkscrew helix when the corkscrew helix is engaged with the main body. The legs 112a, 112b may extend from the central portion in a direction of the longitudinal axis of the main body. In some examples, the legs may extend downward from the central portion of the main body. The legs may have a substantially elongated shape. The legs may be substantially parallel to one another. Some flexibility may be provided so that the legs may be flexed opened or closed relative to one another.

[0052] An interior region 113 of the main body may be provided between the legs 112a, 112b. The interior region may include a space or gap between the legs. The interior region may be a volume of space between the legs. A corkscrew helix 120 may pass into the interior region after passing through the passageway of the central body. A top of a beverage container may be positioned at a portion of the interior region, along with a cork. A cork may be rotated to penetrate the cork and be inserted into the cork. After the corkscrew helix is inserted into the cork, and corkscrew may be further rotated to draw out the cork. As the cork is drawn out of the beverage container, the cork may be pulled up into an upper portion of the interior region.

[0053] An insert 130 may be configured to engage with the corkscrew helix 120. The insert may be positioned within a cavity within the central portion 111 of the main body. A biasing mechanism, such as a spring, may be provided in a biasing space 135 adjacent to the insertDocket No. 6826.001 WO1within the central body. The biasing space may be provided within a central portion of the main body. The biasing space may be part of the cavity within the central portion that may be configured to accept the insert. The biasing space may be adjacent to the insert within the cavity. The biasing space may be laterally adjacent to the insert. The biasing space may or may not be exposed or viewable from an exterior of the main body. For example, an opening may allow a user to view the biasing space and / or biasing mechanism from outside the main body. In some examples, a wall or cover may prevent the biasing space from being viewable or accessible.

[0054] The biasing mechanism may exert a lateral force on the insert, which may be in a direction perpendicular to a longitudinal axis of the main body, A biasing mechanism may include any configuration or material that may provide a biasing force, such as a spring, balloon, piston, pneumatic or hydraulic structure, elastomeric material, flexible structure, memory shaped device, or any other type of biasing mechanism. In some examples, the spring may be a compression spring that may be oriented m a direction to provide lateral force. Other types of springs may include, but are not limited to tension springs, torsion springs, drawbar springs, volute springs, extension springs, or other types of springs. In some examples, the biasing mechanism may include elastic bands. In some examples, the biasing mechanism may include the application of human force. The lateral force may push the insert against the corkscrew helix. When the insert is pushed against the corkscrew helix, the corkscrew helix may not move in a longitudinal direction relative to the main body without rotating along the insert. The insert may prevent the corkscrew helix from sliding or translating relative to the main body (e.g., in a longitudinal direction, or any other direction). The insert may be positioned between the coils of the corkscrew helix, thereby preventing free vertical motion of the corkscrew helix relative to the main body.

[0055] The cork extractor may be configured to remove a cork from a beverage container. The beverage container may include any enclosure or vessel that may include an opening that can be stopped with a cork. When the cork is removed, the liquid within the beverage container may be accessible. In some examples, the beverage container may be a bottle, such as a wine bottle. The wine bottle may have an elongated neck with an opening at the top. The diameter of the wine bottle opening may be less than a maximal diameter along a length of the wine bottle. It can be appreciated that the cork extractor can be used to remove other types ofDocket No. 6826.001 WO1stoppers from various containers, which may include cork, wax, silicone, plastics, polyethylene, biopolyethylene, or other materials that may be penetrated with a corkscrew. Examples of other containers may include bottles, jars, cans, jugs, pitchers, cartons, carafes, or any other type of beverage container. The main body may be sized and / or shaped to fit an opening of a selected type of beverage container.

[0056] FIG. 1B shows a view of a corkscrew helix 120 engaged with an insert 130 within a main body of the cork extractor, according to some examples. A corkscrew helix may include a handle 125 that is positioned at a proximal end of the corkscrew helix. A pointed tip 126 may be provided at a distal end of the corkscrew helix. While a single helix is illustrated for the corkscrew, it can be appreciated that any description of a corkscrew helix can apply to a double helix, triple helix, or any type of multi-helix. In some examples, any description of a helix can apply to any spiral configuration, a conchospiral, a helicoid, a threaded shape, a screw shape, a worm, or any other type of three-dimensional spiral shaped curve that may wind about a central longitudinal axis at a constant angle.

[0057] A handle 125 may be provided at the end of the corkscrew helix 120. The handle may be configured for grasping by a user. In some examples, the handle may be substantially symmetrical about a central plane intersecting with a longitudinal axis of the corkscrew helix. The handle may be configured to rotate about the longitudinal axis of the corkscrew helix. In some examples, the handle may be configured with a knob, a pull, a bar, an ellipsoid, a cylinder, a sphere, a crescent, or any other configuration that a user may grasp. In some examples, the user may grasp the handle so that the longitudinal axis of the corkscrew helix intersects the user’s hand. The handle may be rotated about the longitudinal axis. In some examples, the center of mass of the handle may be in line with the longitudinal axis of the corkscrew helix. A user may twist the handle by rotating the user’s hand (similar to rotating a doorknob).

[0058] A pointed tip 126 of the corkscrew helix may be provided at an end of the corkscrew helix. The pointed tip may be configured to penetrate a cork or any other removable closure of a beverage container. The pointed tip need not be very sharp in order to penetrate the corkscrew. In some examples, the pointed tip may have a slightly rounded or blunted end.

[0059] An insert 130 may be engaged with the corkscrew helix 120. The insert may engage with the corkscrew helix within a central portion of the main body of the cork extractor. InDocket No. 6826.001 WO1some examples, the insert may be a tooth element. Any description herein of an insert may apply to a tooth element and vice versa. The tooth element may include a geometric feature that may be inserted between coils of the corkscrew helix. This may prevent the corkscrew helix from moving straight in a longitudinal fashion. The helix may have to twist in order to cause longitudinal motion of the corkscrew helix. When the tooth element is engaged, the corkscrew helix may not purely translate in a longitudinal direction or other direction. Any motion of the corkscrew helix may be accompanied by a rotation about the longitudinal axis of the corkscrew helix. The corkscrew helix may be prevented from translating directly along the longitudinal rotation without rotation when under a threshold translation value. When the tooth element is engaged, a platform may be created for the corkscrew helix to grip, which may allow the corkscrew helix to drive downwards into a cork or upwards without requiring substantial force in the longitudinal direction (downwards or upwards). A rotational force on the corkscrew helix may be sufficient to deliver the desired longitudinal motion of the corkscrew helix, due to the geometry of the corkscrew helix. Such a configuration may reduce the risk of a cork being pushed into the bottle.

[0060] The insert 130, such as the tooth element, may be pushed against the corkscrew helix 120 with aid of a biasing mechanism. The insert (e.g., tooth element) may be pushed against the corkscrew so that at least a portion of the insert (e.g., tooth element) may be located between one or more coils of the helix. In some examples, the tooth element may penetrate into a cylindrical region defined by the corkscrew shape. The biasing mechanism may be further compressed under higher forces than a typical driving force for the corkscrew helix to penetrate the cork. The higher forces are exerted when the corkscrew reaches its lowest position, and it may rotate freely without lowering further. The higher forces may be experienced when a threshold resistance level is exceeded. When beneath the threshold resistance level, the corkscrew helix may simply rotate past the insert. When the threshold resistance level is exceeded, the helix angle may press inward on the insert (e.g., tooth element), compressing the biasing mechanism. By driving the corkscrew helix forward as it rotates, it may eliminate the need for a user to apply significant vertical pressure to initially force the helix into the cork. In some examples, the tooth element of the insert may include a step 132 or other shape that may form a space where a biasing mechanism may fit. While a step may be illustrated, it can be appreciated that the tooth element could include a recess, a hole, a protrusion, or any other interface that may allow the biasing mechanism to provide aDocket No. 6826.001 WO1directed force against the tooth element. The step 132 or other interfacing mechanism may prevent the biasing mechanism from slipping off the insert or popping out of the main body. The step or other interfacing mechanism may provide a contact surface where a biasing mechanism may provide force in a desired direction.

[0061] In some examples, the insert (e.g., tooth element) may be configured to engage the corkscrew helix, wherein the insert is configured to apply a force to the corkscrew helix to prevent slippage of the corkscrew helix when the corkscrew helix is rotated under below a threshold resistance value, and to allow the corkscrew helix to rotate freely when the corkscrew helix is rotated above the threshold resistance value. When beneath the threshold resistance value, the corkscrew helix may simultaneously move longitudinally while rotating, due to the shape of the corkscrew helix. When above the threshold resistance value, the corkscrew helix may rotate about the longitudinal axis without moving longitudinally. The resistance experienced by the corkscrew and / or insert may be beneath the threshold resistance value while the corkscrew is penetrating into the cork, prior to the handle of the corkscrew contacting the upper surface of the mam body. When the handle of the corkscrew reaches the mam body, the corkscrew may not be able to travel further downwards, which may cause the resistance experienced by the corkscrew and / or the insert to exceed the threshold resistance value. This may result in allowing the corkscrew to rotate within the mam body without traversing further downward. This may be desirable in order to pull the cork upwards out of the beverage container using a rotational movement of the corkscrew. A threshold resistance value may be a value at which the insert (e.g., tooth element) may be pushed back sufficiently to allow for rotation of the corkscrew without translation of the corkscrew. Essentially slippage of the corkscrew may be allowed when the corkscrew is no longer able to move translationally. In some examples, the rotation of the corkscrew may be permitted regardless of the resistance value. When the insert (e.g., tooth element) is engaged, the corkscrew may be rotating and translating at the same time. When the handle of the corkscrew meets the mam body, the corkscrew may no longer be capable of translating due to the force exerted by the main body on the handle, but rotation of the corkscrew may continue. When a user exerts sufficient rotational force on the corkscrew handle, the tooth element may ‘slip’ past the corkscrew turns, which may allow for rotation of the corkscrew’ while the corkscrew’ is not translating longitudinally. In some examples, this value may have a torque value of at least 0.5 Nm, 1.0 Nm, 1.3 Nm, 1.4 Nm, 1.5 Nm, 1.55 Nm, 1.6 Nm, 1.65 Nm, 1.7 Nm, 1.75 Nm, 1.8 Nm, 1.85 Nm, 1.9 Nm, 2.0Docket No. 6826.001 WO1Nm, 2.1 Nm, 2.2 Nm, 2.5 Nm, 3.0 Nm, 3.5 Nm, or 5 Nm. The torque value may be less than any of these values provided or may fall within a range between any two of these values. For example, the torque values may be provided between 1-2 Nm, 1.5-1.9 Nm, or 1.6-1.8 Nm.

[0062] Thus, the insert may be uniquely configured to permit only a first type of motion of the corkscrew during a cork penetrating mode, while permitting a second type of motion of the corkscrew during a cork removal mode. The insert may be configured to allow these different types of motion without altering a motion exerted on the corkscrew (e.g., rotation of the corkscrew). The first type of motion may be a rotating and longitudinal combination motion (e.g,, a drill-down type motion), while the second type of motion may only be a rotational motion without longitudinal motion. In some examples, this insert may be a tooth element, as described herein.

[0063] A tooth element with a biasing mechanism is provided by way of example only and it can be appreciated that the insert can have another configuration that may allow for engagement with the corkscrew helix. Further examples may be provided elsewhere herein and may be provided interchangeably with the tooth element with biasing mechanism. Other configurations or variations may be provided that may provide the same functionality.

[0064] FIG. 2A shows a perspective view of a cork extractor main body 210, according to some examples. The mam body 210 may include a central portion 211. The central portion may be provided at an upper region of the mam body, and may be configured to positioned above a beverage container opening. One or more legs 212a, 212b may extend from the central portion 211. In some examples, a pair of legs can be provided. It can be appreciated that any number of legs may be provided, such as three legs, four legs, five legs, six legs, or more legs. The legs may be distributed circumferentially evenly about a longitudinal axis of the mam body. For example, when two legs are provided, they may be 180 degrees apart from one another about a longitudinal axis of the main body. An interior region 213 may be provided between the legs 212a, 212b.

[0065] The central portion 211 of the main body may include a cavity 220 therein. The cavity may be configured to house an insert within the main body of the cork extractor. The cavity may allow an insert to be housed within the central portion of the main body. The insert may include a tooth element and / or a biasing mechanism, such as a spring. The tooth element and / or biasing mechanism may be housed within the cavity. A passageway 222 may beDocket No. 6826.001 WO1provided through the central body. A corkscrew may pass through the passageway through the central body. The passageway may be oriented along the longitudinal axis. The passageway may be provided along the longitudinal axis of the main body. An upper opening 221 may be provided to accept the corkscrew. The corkscrew may pass through the upper opening, the cavity 220, and the longitudinal passageway 222. In some examples, the passageway may have a sufficiently small diameter to keep the corkscrew oriented in a desired orientation. In some examples, the passageway may not allow much wiggle that may change the orientation of the corkscrew. In some examples, an insert, such as the tooth element, may stabilize the corkscrew regardless of the passageway diameter. The corkscrew may be maintained so that the longitudinal axis of the corkscrew is substantially parallel to and / or colinear with the longitudinal axis of the main body. The insert that exerts a force against the corkscrew may also keep the corkscrew aligned to a desired orientation.

[0066] One or more legs 112a, 112b of the main body may include a lip insert 214a, 214b that may be configured to interface with a beverage container. The lip insert may form a flange or lip that can rest on top of a beverage container. For example, the lip insert may extend into the interior region 213 and may rest on top of the beverage container when a portion of the beverage container is inserted into the interior region. The lip insert may help position the main body of the cork extractor relative to the beverage container. This may ensure that the corkscrew will penetrate a desired portion of the cork (e.g., central region of the cork). The main body may help align the corkscrew when engaged with the beverage container to create a desired penetration of the cork. In some examples, each leg may include one, two, three, four or more lip inserts. Having multiple lip inserts may help provide a greater degree of stabilization of the main body relative to the beverage container. A lip insert may include a cutter insert that may or may not aid in cutting a covering or seal of a beverage container. In some examples, a separate cutting mechanism may be provided beneath the lip insert or may be part of the lip insert itself. A cutting mechanism, such as a cutter insert, may cut through an upper section of a beverage container’s covering or seal when the main body is spun. The lip may remain resting on top of the beverage container’s upper surface while the main body is spun. This spinning motion may allow the cuts to be made in a circular motion.

[0067] One or more legs 112a, 112b of the main body may also include one or more flexible members 215a, 215b. One or more relief cuts 219a, 219b may be provided adjacent to theDocket No. 6826.001 WO1flexible members. The cuts may allow the flexible members to move relative to the rest of the legs. This may allow sectional flexion for the flexible members. The flexible members may be moved inwards or outwards relative to the rest of the legs. In some examples, the flexible members may be bendable at least 3, 5, 10, 15, 20, 25, or 30 degrees relative to the legs. The flexible members may support a cork grip 216a, 216b. The cork grip may include a gripping member 217a, 217b on an interior surface of the flexible member. The gripping member may protrude into an interior region 213 of the main body. The gripping member may be configured to embed into the cork. The gripping member may include one or more pointed tips, rounded tips, bumps, protrusions, fins, spines or any other feature that may grip into the cork. The cork grips 216a, 216b may protrude out of an outer surface of the flexible member, directly opposite the gripping members 217a, 217b. The cork grips may have relatively flat surfaces that a finger may push against comfortably. The cork grips may have a prismatic shape, such as a rectangular prismatic shape, or a trapezoidal shape. The cork grips may have rounded corners and / or edges. When a user presses against the cork grips 216a, 216b from outside the mam body (e.g., squeezing the cork grips together), the flexible members 215a, 215b may flex inwards relative to the rest of the main body, which may cause the gripping members 217a, 217b to be driven into the cork, preventing the cork from moving. The gripping members may be driven into sides of the cork. When the gripping members are driven into the sides of the cork, the cork may be preventing from moving translationally and / or rotationally. This may be useful for gripping the cork in place while the corkscrew is removed from the cork.

[0068] A top of a beverage container may be positioned between the legs of the main body. The main body or the legs of the main body may be formed from a semi-flexible material. This may allow the mam body to adapt to variations in cork size or beverage container sizes.Different thicknesses of a beverage container neck can be accommodated by the flexible main body. The legs of the main body may be flexed together or can be splayed outwards as needed.

[0069] FIG. 2B shows a front view of a cork extractor main body, according to some examples. The main body 210 may include a central portion 211. One or more legs 212a, 212b may extend from the central portion 211. In some examples, a pair of legs can be provided. An interior region 213a, 213b may be provided between the legs 212a, 212b. An exterior surface of the legs may be substantially in line w’ith an exterior surface of the central portion. Alternatively different surface levels can be provided. The legs may be substantially parallel toDocket No. 6826.001 WO1one another when in a resting state. In some examples, the legs may be bendable relative to one another. For example, they can be capable of being splayed outwards at least 3 degrees, 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, or 30 degrees without damage. This may be useful when accommodating beverage containers with a larger neck or opening. The legs may be bendable inwards by at least 3 degrees, 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, or 30 degrees without damage. This may be useful when accommodating beverage containers with a smaller neck or opening, or when gripping a cork that has been extracted from the bottle.

[0070] The central portion 211 of the main body may include a cavity 220 therein. The cavity may be configured to house an insert within the mam body of the cork extractor. The cavity may allow an insert to be housed within the central portion of the main body. The insert may include a tooth element and / or a biasing mechanism, such as a spring. The tooth element and / or biasing mechanism may be housed within the cavity. In some examples, other types of inserts, such as internally threaded spiral shapes or other types of inserts may be used. A passageway may be provided through the central body. A corkscrew may pass through the passageway through the central body. The passageway may be oriented along the longitudinal axis. The passageway may be provided along the longitudinal axis of the main body. An upper opening 221 may be provided to accept the corkscrew. The corkscrew may pass through the upper opening, the cavity 220, and the longitudinal passageway. The corkscrew may be maintained so that the longitudinal axis of the corkscrew is substantially parallel to and / or colinear with the longitudinal axis of the mam body. The insert that exerts a force against the corkscrew may also keep the corkscrew aligned to a desired orientation.

[0071] One or more legs 112a, 112b of the main body may include a lip insert 214a, 214b that may be configured to interface with a beverage container. For example, the lip insert may extend into the interior region 213a, 213b and may rest on top of the beverage container when a portion of the beverage container is inserted into the interior region. In some examples, the lip insert may have a lower surface that may be orthogonal relative to a longitudinal axis of the legs. In some examples, the angle between the lower surface of the lip insert and the lower portion of the leg below the lip insert may be less than 90, 85, 80, 75, or 70 degrees. In some examples, the lip insert may have a tapered or slated upper surface. The lip insert may help position the main body of the cork extractor relative to the beverage container. This mayDocket No. 6826.001 WO1ensure that the corkscrew will penetrate a desired portion of the cork (e.g., central region of the cork). The main body may help align the corkscrew when engaged with the beverage container to create a desired penetration of the cork.

[0072] An interior region beneath the lip inserts 214a, 214b may be a lower interior region 213a. The lower interior region may be provided between lower portions of the legs. A beverage container top, such as a wine bottle top, may fit into the lower interior region. When the main body is engaged with the beverage container, the beverage container top may be gripped around its neck by the lower portions of the legs. The beverage container top may remain in the lower interior region, without traversing past the lip inserts. The beverage container top may be prevented from entering an upper interior region 213b which may be provided above the lip inserts,

[0073] Lower portions of the legs may include an indentation or recessed portion 218a, 218b. This recessed portion may accommodate a protruding portion of a beverage container top. For example, a neck of the beverage container may have a ring, flange, or threads that may extend from the beverage container. The indentation or recessed portion may accept the ring or flange so that the remaining portions of the legs may make stable contact with the rest of the beverage container. The recessed portion may have a sufficient width to accommodate different positionings or sizing of any protruding neck features.

[0074] One or more legs 112a, 112b of the main body may also include one or more flexible members. The flexible members to move relative to the rest of the legs. The flexible members may support a cork grip 216a, 216b. The cork grip may include a gripping member 217a, 217b on an interior surface of the flexible member. The gripping member may protrude into an upper interior region 213b of the main body. The gripping member may be configured to embed into the cork. The gripping member may include one or more pointed tips, rounded tips, bumps, protrusions, fins, spines or any other feature that may grip into the cork. The cork grips 216a, 216b may protrude out of an outer surface of the flexible member, directly opposite the gripping members 217a, 217b. The cork grips may have relatively flat surfaces that a finger may push against comfortably. When a user presses against the cork grips 216a, 216b from outside the main body (e.g., squeezing the cork grips together), the flexible members may flex inwards toward an upper interior region 213b, which may cause the gripping members 217a, 217b to be driven into the cork, preventing the cork from moving. During a cork removalDocket No. 6826.001 WO1process, a corkscrew may be turned so that once the corkscrew is embedded within the cork, the cork may be lifted out of the beverage container. The beverage container top may remain in a low’er interior region 213a, while the cork may be lifted up into the upper interior region 213b. When the cork is clear of the beverage container (e.g., above the lower surface of the lip inserts 214a, 214b) and / or reaches the lower surface of the central portion 211 at the top the upper interior region 213b, it may be desirable to remove the corkscrew’ from the cork. A user may squeeze the cork grips 216a, 216b together so that the gripping members may be driven into the sides of the cork. When the gripping members are driven into the sides of the cork, the cork may be prevented from rotating. This may keep the cork in place while the corkscrew is removed from the cork,

[0075] In some examples, each leg may have a corresponding set of cutter grips (e.g., single cutter grip, pair of cutter grips, multiple cutter grips), and recessed portion. Each leg may have a cork grip with gripping members supported on a corresponding flexible member,

[0076] FIG. 2C shows a side view of a cork extractor main body, according to some examples. The main body 210 may include a central portion 211. The central portion may be provided at an upper region of the mam body, and may be configured to positioned above a beverage container opening. One or more legs 212a may extend from the central portion 211. In some examples, a pair of legs can be provided. An interior region may be provided between the legs. / Xn upper opening 221 may be provided at an upper surface of the central portion.

[0077] A leg 112a of the main body may include one or more flexible members 215a. One or more relief cuts 219a may be provided adjacent to a flexible member 215. The cuts may allow the flexible member to move relative to the rest of the leg 212a. The cuts may form gaps between portions of the flexible member and the rest of the leg. In some examples, a pair of cuts may be provided longitudinally with the flexible member between the longitudinal cuts. The longitudinal cuts may be substantially parallel to one another. In some examples, a lower cut may be provided between a lower end of the flexible member and the rest of the legs. The flexible member may be anchored at an upper portion of the flexible member. The flexible member may be connected to the rest of the leg and / or central body at the top of the flexible member. It can be appreciated that variations may be provided, such as having a cut between an upper end of the flexible member and the rest of the legs or central body so that the flexibleDocket No. 6826.001 WO1member may be anchored at a lower portion of the flexible member. The flexible member can have any shape or orientation.

[0078] A flexible member 215a may support a cork grip 216a. The cork grip may include a gripping member on an interior surface of the flexible member. The gripping member may protrude into an interior region of the main body. The gripping member may be configured to embed into the cork. The cork grip 216a may protrude out of an outer surface of the flexible member, directly opposite the gripping member. The cork grips may have relatively flat surfaces that a finger may push against comfortably. When a user presses against the cork grip 216a from outside the main body (e.g,, squeezing the cork grips together), the flexible member 215a may flex inwards relative to the rest of the mam body, which may cause the gripping member to be driven into the cork, preventing the cork from moving. In some examples, the flexible member may also permit outward flexing relative to the rest of the leg, which may be useful when a cork is being driven upwards and may push against the gripping member as it traverses the interior region upwards. Allowing the gripping member to flex outwards may prevent the cork from getting stuck while it moves upwards.

[0079] FIG. 2D shows a cross-section of a cork extractor main body, according to some examples. The mam body 210 may include a central portion 211. One or more legs 212a, 212b may extend from the central portion 211. In some examples, a pair of legs can be provided. An interior region 213 may be provided between the legs 212a, 212b.

[0080] The central portion 211 of the mam body may include a cavity 220 therein. The cavity may be configured to house an insert within the main body of the cork extractor. The cavity may allow an insert to be housed within the central portion of the main body. The insert may include a tooth element and / or a biasing mechanism, such as a spring. The tooth element and / or biasing mechanism may be housed within the cavity. In some examples, other types of inserts, such as internally threaded spiral shapes or other types of inserts may be used. In some examples, the cavity may be oriented substantially laterally to accommodate an insert and a biasing mechanism, such as a spring that may be positioned laterally relative to the insert. For example, a spring may be positioned laterally relative to a tooth element and provide a force that may be applied in a lateral direction, orthogonal to a longitudinal axis 205 of the main body.Docket No. 6826.001 WO1

[0081] A passageway 222 may be provided through the central body. The passageway may be a channel, or an internal feature within the central portion of the main body. The passageway may have a substantially cylindrical shape. In some examples, the passageway may have any other shape, such as prismatic shape or spiral shape. A corkscrew may pass through the passageway through the central body. The passageway 222 may be oriented along the longitudinal axis 205. The passageway may be provided along the longitudinal axis of the main body. A longitudinal axis of the passageway may be colinear with a longitudinal axis of the main body. An upper opening 221 may be provided to accept the corkscrew. In some examples, the upper opening may have a greater diameter than the passageway 222, This may create an internal shelf 207 within the central portion of the main body. In some examples, an internal shelf may not be required, and a tapered or curved connection may be provided. In some examples, the upper opening and the passageway may have the same diameter.

[0082] The corkscrew may pass through the upper opening 221, the cavity 220, and the longitudinal passageway 222. The corkscrew may be maintained so that the longitudinal axis of the corkscrew is substantially parallel to and / or colinear with the longitudinal axis of the main body. The insert that exerts a force against the corkscrew may also keep the corkscrew aligned to a desired orientation. The insert may exert a force against the corkscrew to prevent the corkscrew from slipping up or down relative to the main body translationally. In order to move upwards or downwards, the corkscrew may need to be rotated. This may occur due to the force exerted by the insert on the corkscrew.

[0083] In some examples, the corkscrew may include a shaped feature that may reach the inner shelf 207 of the central portion of the main body. When the shaped feature reaches the inner shelf, the corkscrew may not descend further. If the corkscrew is further rotated, the corkscrew may move in a rotational direction but may not translate up or down, due to the limit provided by the inner shelf. This may create increased resistance that may rise above a threshold, causing a cork to be pulled up out of a beverage container. In some examples, an inner shelf may not be provided or required. Instead, a shaped feature of the corkscrew, such as a handle may come into contact with an upper surface 206 of the main body. When the shaped feature reaches the upper surface, the corkscrew may not descend further. Similarly, if the corkscrew is further rotated, the corkscrew may move in a rotational direction but may not translate up or down, due to the limit provided by the upper surface. This may create increasedDocket No. 6826.001 WO1resistance that may rise above a threshold, causing a cork to be pulled up out of a beverage container.

[0084] One or more legs 112a, 112b of the main body may include a lip insert 214a, 214b that may be configured to interface with a beverage container. For example, the lip insert may extend into the interior region 213 and may rest on top of the beverage container when a portion of the beverage container is inserted into the interior region. The lip insert may help position the main body of the cork extractor relative to the beverage container. This may ensure that the corkscrew will penetrate a desired portion of the cork (e.g., central region of the cork). The mam body may help align the corkscrew when engaged with the beverage container to create a desired penetration of the cork.

[0085] One or more legs 112a, 112b of the main body may also include one or more flexible members 215a, 215b. The flexible members may move relative to the rest of the legs. The flexible members may support a cork grip 216a, 216b. The cork grip may include a gripping member 217a, 217b on an interior surface of the flexible member. The gripping member may protrude into an interior region 213 of the main body. The gripping member may be configured to embed into the cork. The gripping member may include one or more pointed tips, rounded tips, bumps, protrusions, fins, spines or any other feature that may grip into the cork. The gripping members 217a, 217b may be integrally formed with the cork grips and / or flexible members. The cork grips may have relatively flat surfaces that a finger may push against comfortably. One or more cuts 219a, 219b may be provided between a portion of the flexible member and the rest of the legs to aid in flexibility. For example, one or more cuts may be provided at or around the cork grips.

[0086] When a user presses against the cork grips 216a, 216b from outside the main body (e.g., squeezing the cork grips together), the flexible members 215a, 215b may flex inwards toward an interior region 213, which may cause the gripping members 217a, 217b to be driven into the cork, preventing the cork from moving. During a cork removal process, a corkscrew may be turned so that once the corkscrew is embedded within the cork, the cork may be lifted out of the beverage container. A user may then squeeze the cork grips 216a, 216b together so that the gripping members may be driven into sides of the cork. When the gripping members are driven into the sides of the cork, the cork may be preventing from rotating, which may keep the cork in place while the corkscrew is removed from the cork.Docket No. 6826.001 WO1

[0087] Any of the features of the main body may be optional or different variations of the features may be provided. The main body may be formed from a single integral piece or can be formed from multiple pieces that may be attached together. In some examples, the main body may be formed from injection molding or casting, or any other technique. The main body may be formed from a rigid or semi-rigid material. In some examples, the main body may be formed from a plastic, such as polypropylene (PP), polyethylene (PE), acrylonitrile butadiene styrene (ABS), polyurethane (PU), thermoplastic polyurethane (TPU) or an elastomeric material, such as rubber, silicone, nitrile (NBR), neoprene (CR), ethylene propylene and diene monomer (EPDM), or other materials. The main body may be formed from wood, wire, hinged metal, any metal material (e.g., elemental metal or metal alloy), or composite materials. Any combinations of these materials or types of materials may be utilized in forming the main body. In some examples, a portion of the main body may be formed from a first material while a second portion of the main body may be formed from a second material,

[0088] A corkscrew, including a corkscrew helix and / or handle may be formed from any of these materials or combinations of these materials. A corkscrew helix may be formed from any material with a hardness configured to withstand repeated penetration of a cork or other stopper.

[0089] FIG. 3 shows a cross-section of a cork extractor mam body 310 with an insert 330, according to some examples. The main body 310 may include a central portion 311 with one or more legs 312a, 312b extending therefrom.

[0090] The central portion 311 of the main body may include a cavity 324 that may accept an insert 330. In some examples, the insert may include a tooth that may be movable relative to the main body. A biasing mechanism, such as a spring, may provide a force 326 laterally against the tooth. The tooth may be biased inwards toward a passageway 323 that may extend longitudinally through the central portion 311 of the main body 310.

[0091] A corkscrew 320 may be inserted into the main body. The corkscrew may form a helix or any other type of spiral shape. In some examples, the insert may be biased against the corkscrew and may fit between individual turns 321a, 321b of the corkscrew. In some examples, turns may be referred to as helical threads of the corkscrew. As the insert is provided between the turns, the corkscrew may be prevented from simply sliding upwards or downwards. If a force is exerted purely upwards or downwards without rotation, the corkscrewDocket No. 6826.001 WO1may remain stuck within the main body. In some examples, the insert may push against a far portion 322 of the corkscrew. The force exerted by the insert against the far portion 322 of the corkscrew may help keep the corkscrew aligned within the passageway 323. Furthermore, the shape and dimensions of the passageway itself may help keep the corkscrew aligned relative to the main body 310 of the cork extractor, which may result in the corkscrew being precisely positioned within a desirable region of the cork for extraction.

[0092] The corkscrew 320 may include a handle 325. In some examples, when the corkscrew is rotated, the corkscrew may descend into the main body until the handle 325 contacts an upper surface of the mam body, or any other features of the corkscrew is stopped by any surface of the main body. At this point, the corkscrew may be fully descended, and any further rotation of the corkscrew may not result in up or down translational movement of the corkscrew. As the corkscrew is further rotated, the cork may traverse up the corkscrew and may be pulled out of the beverage container (e.g., wine bottle). The mam body may be disengaged from the beverage container,

[0093] FIG. 4A provides a view of a tooth element 430 of an insert, according to some examples. In some example, the tooth element may be formed from a single integral piece. The tooth element may be formed from any material as described elsewhere herein, such as a plastic or elastomeric material. In some examples, the tooth element can be formed from a metal or other material.

[0094] The tooth element may have any shape that may allow it to press against the corkscrew to prevent it from slipping vertically, while still permitting smooth rotational movement of the corkscrew. The tooth element may receive a biasing force from a biasing mechanism that may be positioned adjacent to the tooth element along a biasing region 432. The biasing region may include a step, recess, cutout, hole, or any other surface feature that may receive a force from the biasing mechanism. In some examples, the biasing region may be shaped to provide a desired alignment of the biasing mechanism relative to the tooth. The biasing region may be shaped to maintain a position of the biasing mechanism without the biasing mechanism falling out or re-orienting.

[0095] The tooth element may include an upper surface 434 and an opposing lower surface. In some examples, the upper and lower surfaces may be substantially parallel. At least one turn of the corkscrew may be positioned over the upper surface, and at least one subsequent turn ofDocket No. 6826.001 WO1the corkscrew may be positioned beneath the lower surface. Thus, the tooth element may be positioned between two turns of the corkscrew. The tooth element may include a curved surface 431 that may allow the tooth to fit between the turns of the corkscrew while allowing a far end 433 of the tooth to contact a far portion of the corkscrew and exert a portion against the far portion of the corkscrew. The curved shape of the tooth may allow for good contact with the various portions of the corkscrew, which may allow for the corkscrew to be tightly held within the cork extractor. This may prevent the corkscrew from wiggling, thereby reducing a risk of inaccuracy of piercing the cork. This may also allow for a positive user experience, while a user may rotate the corkscrew via a handle. In some examples, the curvature of the curved surface 431 may match the curvature of the corkscrew.

[0096] FIG. 4B provides an additional view of a tooth element 430 of an insert, according to some examples. The tooth element may include an upper surface 434 and an opposing lower surface. The tooth element may be positioned between coils of the corkscrew, thereby preventing the corkscrew from vertically sliding up or down relative to the cork extractor without rotating the corkscrew. The tooth element may be biased against the corkscrew to provide a frictional connection with the corkscrew. This may prevent the corkscrew from moving relative to the main body when inserted within the main body absent an outside force. The biasing force from the tooth element against the corkscrew, may keep the corkscrew squeezed in position within a passageway, and may prevent the corkscrew from wiggling or sliding relative to the mam body.

[0097] The tooth element may include a biasing region 432 which may receive a biasing force from a biasing element. The biasing region may be indented into the tooth element or form a step within the tooth element to allow the biasing element to fit within the tooth element within a cavity of the main body. The biasing element may include a surface 435 that may receive the force from the biasing element. The surface may be oriented substantially orthogonally to a primary direction of force from the biasing element. The primary direction of force may be substantially lateral, pushing the corkscrew into a side of the passageway.

[0098] FIG. 5A shows a guided cork extractor 500, according to some examples. A cork extractor 500 may include a main body 510. A corkscrew 520 may pass through the main body. The corkscrew may include a handle 525 at a proximal end of the corkscrew helix. AnDocket No. 6826.001 WO1insert may fit within the main body and may be configured to interface with the corkscrew helix.

[0099] A main body 510 of the cork extractor 500 may include one or more legs 512a, 512b that may extend from a central portion 511 of the main body. An interior region 513 may be provided between the legs 512a, 512b. The central portion 511 of the main body may include a passageway through which the corkscrew 520 may pass. The passageway may be oriented along a longitudinal axis 505 of the main body. The longitudinal axis of the main body may be parallel to or collinear with a longitudinal axis of the corkscrew when the corkscrew helix is engaged with the main body. The legs 512a, 512b may extend from the central portion in a direction of the longitudinal axis of the main body. In some examples, the legs may extend downward from the central portion of the main body. The legs may have a substantially elongated shape. The legs may be substantially parallel to one another. Some flexibility may¬ be provided so that the legs may be flexed opened or closed relative to one another,

[0100] An interior region 513 of the main body may be provided between the legs 512a, 512b. The interior region may include a space or gap between the legs. The interior region may be a volume of space between the legs. A corkscrew 520 may pass into the interior region after passing through the passageway of the central body. A top of a beverage container may be positioned at a portion of the interior region, along with a cork. As the corkscrew is inserted into the cork, and corkscrew may be further rotated to draw out the cork. As the cork is drawn out of the beverage container, the cork may be pulled up into an upper portion of the interior region.

[0101] An insert or interior feature of the main body may be configured to engage with the corkscrew 520. The insert or interior feature may be positioned within the central portion 511 of the main body. When engaged with the corkscrew, the corkscrew may not slide longitudinally with respect to the main body. The corkscrew may only move longitudinally when being simultaneously rotated. Any description herein of an insert may also similar features that may be integrated with, formed on, or attached to the mam body.

[0102] The corkscrew 520 may include a handle 525. The handle may be a crank or similar turning handle. The handle may include a grip 527 that may be supported on a lateral portion of the crank. The grip 527 may have a longitudinal axis 528 that may be substantially parallel to a longitudinal axis 505 of the main body. The grip may rotate about its longitudinal axis.Docket No. 6826.001 WO1The grip may rotate relative to the lateral portion of the crank. In some examples, the longitudinal axis 528 of the grip is not colinear with the longitudinal axis 505 of the main body. The longitudinal axis 528 of the grip may revolve around the longitudinal axis 505 of the main body as the crank is turned. The grip 527 of the crank may revolve around the longitudinal axis 505 of the main body. A user may be able to hold the grip with a particular orientation, and then turn the crank in a circular motion in order to turn the handle of the corkscrew. The force exerted on the handle of the corkscrew may be provided from a location that is not colinear with the longitudinal axis of the corkscrew. A distance d may be provided between the longitudinal axis 528 of the grip and the longitudinal axis 505 of the mam body. This may allow for increased torque (torque τ = force applied F × distance d) to be provided when turning the corkscrew, making it easier to drive the corkscrew into the cork. This may be contrasted to a handle where the twisting force is centered at the longitudinal axis, and where the fingers that apply the twisting force are closer to the longitudinal axis at a second distance d2. When d2 < d, it can be appreciated that less torque will be generated when the force applied is closer to the longitudinal axis of the corkscrew. The torque using the crank handle with grip may be expressed as T = ~~ x where T2 IS the torque generated by providing the twisting forceon the handle. Thus, if the distance d to the grip of the crank is twice the distance than a distance d2 where the force is exerted on the handle by twisting, twice the torque is generated, which means that only half the effort is needed to turn the handle and extract the cork. It can be appreciated that the force needed to generate the same amount of torque F2 = — x p which ^2 indicates that it takes half the force to turn the handle and extract the cork with the increased distance. In some examples, the cork extractor configuration may allow for the distance to be at least 1 cm, 2 cm, 3 cm, 3.5 cm, 4 cm, 4.5 cm, 5 cm, 5.5 cm, 6 cm, 6.5 cm, 7 cm, 10 cm, 12 cm, 15 cm or more.

[0103] Data was collected for required forces and torques in order to reach a threshold torque value that would allow for the cork to be lifted at varying distances. A force gauge was used in conjunction with varying handle sizes in order to measure a force needed to lift a cork from the bottle by rotation of the handle. This may indicate a threshold amount of force where rotation of the handle passes from causing a corkscrew to be rotated and moving in a longitudinal direction to where the corkscrew is stopped from moving in a longitudinal direction and moves rotationally in response to the turning of the handle.Docket No. 6826.001 WO1Handle radius Force to Lift Force to Lift Force to Lift Force to Lift Torque to Lift Cork (Trial 1) Cork (Trial 2) Cork (Trial 3) Cork (Avg) Cork3.6 cm 45.0 N 46.8 N 46.3 N 46.0 N 1.7 Nm5.4 cm 34.1 N 34.6 N 33.9 N 34.2 N 1.8 NmAs illustrated, a relatively consistent torque value may be required. A torque value or threshold torque value may have such values or some variations thereof. An increase in radial distance yielded a reduction in required force. For instance, a 50% increase in radial distance yielded about a 26% reduction in required force. This may illustrate that less force may be required when using a longer handle, which may be enabled by the configuration of the cork extraction device. The corkscrew may be sufficiently stabilized via the inserts as described, which may allow for a user to utilize a longer handle and use configurations, such as cranks, which may allow the force to be exerted at a greater distance from the longitudinal axis.

[0104] In some examples, less than 50 N, 48 N, 47 N, 46 N, 45 N, 44 N, 43 N, 40 N, 38 N, 36 N, 35 N, 34 N, 33 N, 32 N, 30 N, 25 N, or 20 N may be required to be exerted on the handle in order to allow the cork to be penetrated and lifted out of the bottle. Any force values less than those described herein or falling within a range between any two of these values may be provided. In some examples, the force required may be between 1-50 N, 10-50 N, 20-48 N, or 30-48N, The amount of force may depend on a length of the handle or where the distance at which the force is applied to the handle relative to a turning axis of the handle. The force exerted on the handle may be provided in a lateral direction, orthogonal to a radius of the handle.

[0105] Despite the primary force being applied from outside the longitudinal axis 505 of the main body, the corkscrew may remain substantially aligned and may be driven upwards or downwards through the rotational motion, due to an insert or internal features within the mam body. The insert or internal features may engage with the corkscrew turns so that when a rotational force is provided on the corkscrew, the corkscrew naturally moves upwards or downwards, depending on a direction of rotation. An orthogonal force applied to a handle, whether directly manually or by a crank configuration, may be sufficient to cause the corkscrew to move up or down, due to an insert or internal features. The insert or internal features may hold the corkscrew to take advantage of the corkscrew shape without requiring excessive downwards force from a user while providing the rotational moment. In someDocket No. 6826.001 WO1examples, the user need not provide any downward or upward force when turning the corkscrew in order to cause a desired upward or downward motion of the corkscrew. For example, the corkscrew may be capable of penetrating the cork, and pulling the cork out of the beverage container while receiving less than 30 N, 20 N, 16 N, 15 N, 14 N, 13 N, 12 N, 11 N, 10 N, 8 N, 7 N, 6 N, 5 N, 4 N, 3 N, 2N, 1 N, 0.5 N, or 0.1 N of force by a user in the longitudinal direction. Rotational force exerted on the handle may be sufficient on its own to cause the corkscrew to penetrate into the cork and pull the cork out of the beverage container.

[0106] FIG. 5B shows a view of a corkscrew 520 engaged with an insert 530 within a main body 510 of the cork extractor 500, according to some examples. A corkscrew may include a handle 525 that is positioned at a proximal end of the corkscrew. A pointed tip 526 may be provided at a distal end of the corkscrew. The corkscrew may have a helical shape, or any other spiral shape as described elsewhere herein. Any description herein of a corkscrew may apply to a corkscrew helix and vice versa. The corkscrew may define a cylindrical region.

[0107] A handle 525 may be provided at the end of the corkscrew 520. The handle may be a crank that may include a grip 527 for grasping by a user. In some examples, the handle may be asymmetrical about a central plane intersecting with a longitudinal axis of the corkscrew. The handle may be configured to rotate about the longitudinal axis of the corkscrew. In some examples, the user may grasp the grip so that the longitudinal axis of the corkscrew helix need not intersect the user’s hand. The handle may be rotated about the longitudinal axis. In some examples, the center of mass of the handle may be off center with the longitudinal axis of the corkscrew. A user may turn the crank by moving the grip in a circular pattern around the longitudinal axis of the corkscrew.

[0108] An insert 530 may be engaged with the corkscrew 520. The insert may engage with the corkscrew helix within a central portion of the main body of the cork extractor. The insert may include an internally threaded feature. The insert may include a geometric feature that may be inserted between coils of the corkscrew helix. For example, a complementary threaded pattern (e.g., indented spiral or helical pattern) relative to the corkscrew helical shape may be formed within the insert. This may prevent the corkscrew from moving straight in a longitudinal fashion. The corkscrew may have to twist in order to cause longitudinal motion of the corkscrew. When the corkscrew is engaged within the insert, the corkscrew may not purelyDocket No. 6826.001 WO1translate in a longitudinal direction or other direction. Any motion of the corkscrew may be accompanied by a rotation about the longitudinal axis of the corkscrew.

[0109] The insert 530 may be positioned around the corkscrew 520. In some examples, the insert may be provided around at least 50%, 60%, 70%, 80%, 90%, 95% or a full 100% of the circumference of the corkscrew. The insert may be tightly fitted around the corkscrew so that at least a portion of an internal feature of the insert may be located between one or more coils of the helix. An internal feature of the insert may enter into a cylindrical region defined by the corkscrew shape. The insert may provide a contact surface around the circumference of the corkscrew, which may keep the corkscrew tightly positioned within the mam body, preventing slippage or wiggle of the corkscrew,

[0110] In some examples, the insert may be configured to engage the corkscrew helix, wherein the insert is configured to apply a force to the corkscrew helix to prevent slippage of the corkscrew helix when the corkscrew helix is rotated under below a threshold resistance value, and to allow the corkscrew helix to rotate freely when the corkscrew helix is rotated above the threshold resistance value. When beneath the threshold resistance value, the corkscrew helix may simultaneously move longitudinally while rotating, due to the shape of the corkscrew helix. When above the threshold resistance value, the corkscrew helix may rotate about the longitudinal axis without moving longitudinally. The resistance experienced by the corkscrew and / or insert may be beneath the threshold resistance value while the corkscrew is penetrating into the cork, prior to the handle of the corkscrew contacting the upper surface of the main body. When the handle of the corkscrew reaches the main body, the corkscrew may not be able to travel further downwards, which may cause the resistance experienced by the corkscrew and / or the insert to exceed the threshold resistance value. This may result in allowing the corkscrew to rotate within the main body without traversing further downward. This may be desirable in order to pull the cork upwards out of the beverage container using a rotational movement of the corkscrew.

[0111] Thus, the insert may be uniquely configured to permit only a first type of motion of the corkscrew during a cork penetrating mode, while permitting a second type of motion of the corkscrew during a cork removal mode. The insert may be configured to allow these different types of motion without altering a motion exerted on the corkscrew (e.g., rotation of the corkscrew). The first type of motion may be a rotating and longitudinal combination motionDocket No. 6826.001 WO1(e.g., a drill-down type motion), while the second type of motion may only be a rotational motion without longitudinal motion.

[0112] In some examples, the insert may be formed from a semi-rigid material that may prevent slippage of the corkscrew beneath the threshold resistance value, but allow for the corkscrew to rotate without translating when above the threshold resistance value. The insert may be sufficiently rigid in order to prevent the corkscrew from moving longitudinally without moving rotationally. In some examples, the insert may be formed from an elastomeric material, such as such as rubber, silicone, nitrile (NBR), neoprene (CR), ethylene propylene and diene monomer (EPDM), or other materials. The insert may be formed from a material that may allow for some flex or malleability when the resistance exceeds the threshold resistance value.

[0113] An insert within internal threaded or helical features is provided by way of example only and it can be appreciated that the insert can have another configuration that may allow for engagement with the corkscrew. Further examples may be provided elsewhere herein and may be provided interchangeably with the insert with the internal geometric features (e.g., threaded features). Other configurations or variations may be provided that may provide the same functionality.

[0114] FIG. 6 shows a cross-section of a cork extractor 600 with an insert 630, according to some examples. The main body 610 may include a central portion 611 with one or more legs 612a, 612b extending therefrom. An interior region may be provided between the legs.

[0115] A corkscrew 620 may be inserted into the main body 610. The corkscrew' may move upwards or downwards relative to the main body when the corkscrew is rotated relative to the main body. Rotating the corkscrew in a first direction may cause the corkscrew to move downwards, while rotating the corkscrew in a second opposing direction may cause the corkscrew to move upwards. The corkscrew may include a handle 625. The handle may have any configuration as described elsewhere herein. In some examples, the handle may include a crank wdth a grip 627 that may pivot relative to lateral portion 626 of the handle. The grip may be attached to the lateral portion with aid of a pin 629, shaft, or another connector. The pm may allow the grip to spin relative to the lateral portion of the handle. In some examples, the helical portion of the corkscrew may be provided within a recessed portion 628 of the handle. A proximal end of the corkscrew may be embedded within the handle or attached to the handleDocket No. 6826.001 WO1in any manner. The corkscrew may be fixed relative to the handle and may not move relative to a lateral portion of the handle.

[0116] The central portion 611 of the main body may include a passageway 640 that may accept an insert 630. The passageway 640 that may extend longitudinally through the central portion 611 of the main body 610. The insert may be tightly fitted into the passageway or may be affixed relative to the passageway. The passageway may have a shape that may be complementary to an exterior surface or shape of the insert. The insert may not rotate relative to the passageway. Any features or description of the insert may also apply to internal geometric features that may be directly formed within the central body without requiring a separate insert.

[0117] A corkscrew 620 may be inserted into the main body. The corkscrew may fit through the passageway 640 of the main body. The corkscrew may form a helix or any other type of spiral shape. In some examples, the insert may fit tightly around the corkscrew and may have internally protruding features 631 that may fit between individual turns 621a, 621b of the corkscrew. The individual turns of the corkscrew' may fit within internally recessed features 632 of the insert. As protruding feature of the insert is provided between the turns, the corkscrew may be prevented from simply sliding upwards or downwards. If a force is exerted purely upwards or downwards without rotation, the corkscrew may remain stuck within the main body. The insert may exert force around a circumference of the corkscrew. The force exerted by the insert tightly around the corkscrew may help keep the corkscrew aligned within the passageway 640. Furthermore, the shape and dimensions of the passageway itself may help keep the corkscrew aligned relative to the main body 610 of the cork extractor, which may result m the corkscrew being precisely positioned within a desirable region of the cork for extraction.

[0118] A main body 610 may include a plurality of legs 612a, 612b. In some examples, an indentation 615a, 615b may be provided between the legs and the central portion 611 of the main body. The indentation may allow for a reduce thickness to be provided between the legs and the central body. This may allow the legs to flex or bend relative to the central portion. A reduced thickness may allow for greater flexibility or bending range of the legs relative to the central portion of the main body. The legs may be substantially parallel to one another when in a resting state. In some examples, the legs may be bendable relative to one another. ForDocket No. 6826.001 WO1example, they can be capable of being splayed outwards at least 3 degrees, 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, or 30 degrees without damage. This may be useful when accommodating beverage containers with a larger neck or opening. The legs may be bendable inwards by at least 3 degrees, 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, or 30 degrees without damage. This may be useful when accommodating beverage containers with a smaller neck or opening, or when gripping a cork that has been extracted from the bottle.

[0119] One or more legs 612a, 612b of the main body may include a lip insert 614a, 614b that may be configured to interface with a beverage container. For example, the lip insert may extend into the interior region 613a, 613b and may rest on top of the beverage container when a portion of the beverage container is inserted into the interior region. In some examples, the lip insert may have a lower surface that may be orthogonal relative to a longitudinal axis of the legs. In some examples, the angle between the lower surface of the lip insert and the lower portion of the leg below the lip insert may be less than 90, 85, 80, 75, or 70 degrees. In some examples, the lip insert may have a tapered or slated upper surface. The lip insert may help position the main body of the cork extractor relative to the beverage container. This may ensure that the corkscrew will penetrate a desired portion of the cork (e.g., central region of the cork). The main body may help align the corkscrew when engaged with the beverage container to create a desired penetration of the cork.

[0120] An interior region beneath the lip inserts 614a, 614b may be a lower interior region 613a. The lower interior region may be provided between lower portions of the legs. A beverage container top, such as a wine bottle top, may fit into the lower interior region. When the main body is engaged with the beverage container, the beverage container top may be gripped around its neck by the lower portions of the legs. The beverage container top may remain in the lower interior region, without traversing past the lip inserts. The beverage container top may be prevented from entering an upper interior region 613b which may be provided above the lip inserts.

[0121] During a cork removal process, a corkscrew may be turned so that once the corkscrew is embedded within the cork, the cork may be lifted out of the beverage container. The beverage container top may remain in a lower interior region 613a, while the cork may be lifted up into the upper interior region 613b. When the cork is clear of the beverage container (e.g.,Docket No. 6826.001 WO1above the lower surface of the lip inserts 614a, 214b) and / or reaches the lower surface of the central portion 611 at the top the upper interior region 613b, it may be desirable to remove the corkscrew from the cork. A user may squeeze the legs 612a, 612b together so that the cork is gripped between the legs. In some examples, the legs may include gripping members which may include pointed surfaces or other members that may be embedded into the sides of the cork when sufficient force is provided. When the gripping members are driven into the sides of the cork, the cork may be preventing from rotating, which may keep the cork in place while the corkscrew is removed from the cork. In some examples, the inner surfaces of the legs do not require gripping members and the friction from the inner surface of the legs themselves may be sufficient to prevent the cork from rotating, keeping the cork in place while the corkscrew is removed from the cork. In some examples, an elastomeric or high friction material may be provided on an inner surface of the legs in order to aid in grip,

[0122] The legs 612a, 612b of the main body 610 may or may not include flexible members as described elsewhere herein. In some examples, the legs may be substantially identical to one another, which may allow the main body to be substantially symmetrical about a vertical plane including the longitudinal axis. In some examples, the legs may include one or more differences relative to one another, which may prevent the main body from being symmetrical about a vertical plane including the longitudinal axis. A first leg 612a may include a cutting feature 642 which may be used to cut a cover of a beverage container, such as a paper, wax, tape, foil, aluminum, or plastic cover, or any type of seal. The cutting features may be provided on an interior surface of a leg, an outside surface of the leg, a central body, or any other portion of the mam body. In some examples, the lip inserts 614 may be used to cut the cover of the beverage container without requiring a separate cutting feature. The lip inserts may have a pointed end or tip that may be rotated around the beverage container to cut a circumference of the beverage cutter. Other similar features may be formed on an internal surface of the legs. A second leg 612b may include one or more formed features 641 that may be gripped by a user’s hand. For example, the formed features may include finger rests.

[0123] The corkscrew 620 may include a handle 625. In some examples, when the corkscrew is rotated, the corkscrew may descend into the main body until the handle 625 contacts an upper surface of the main body, or any other features of the corkscrew is stopped by any surface of the main body. At this point, the corkscrew may be fully descended, and any furtherDocket No. 6826.001 WO1rotation of the corkscrew may not result in up or down translational movement of the corkscrew. As the corkscrew is further rotated, the cork may traverse up the corkscrew and may be pulled out of the beverage container (e.g., wine bottle). The mam body may be disengaged from the beverage container.

[0124] FIG. 7A shows a view of a threaded insert 730, according to some examples. The insert may include one or more internal geometric features, such as threads, helix, spiral, or other shapes. The internal geometric features may be complementary to a shape of the corkscrew. The internal geometric features may include protruding portions 731 that may hug or come between turns of the corkscrew. The corkscrew turns may fit into recessed portions 732 of the geometric features. The insert may be formed so that the corkscrew tightly fits with the geometric features, so that the corkscrew can not slip vertically past the protruding portions between the coils. The corkscrew must be rotated in order to allow for longitudinal motion of the corkscrew. The corkscrew may follow the recessed portions 732 of the geometric features in order to gradually turn and move upwards or downwards. In some examples, when a resistance falls beneath a resistance threshold level, the corkscrew may only move by rotating and moving longitudinally at the same time, due to the corkscrew geometry. When resistance falls above the resistance threshold level, the corkscrew may rotate in place without moving longitudinally. The internal features may be formed from a material that may have some flexibility to allow such motion when the resistance exceeds the resistance threshold level.

[0125] The insert may include an outer surface or geometry that may be configured to fit within a passageway of a main body. The outer surface or geometry may have a shape that is complementary to an internal shape of the passageway of the main body, or a portion of the passageway of the main body. The insert may have a substantially square, rectangular, triangular, pentagonal, hexagonal, octagonal, circular, elliptical, or other cross section. In some examples, the cross section may be shaped so that the insert is not rotationally symmetrical about its longitudinal axis. This may prevent the insert from turning within the main body when the insert is fitted within the mam body. In some examples, the insert may be friction fit within the main body. Geometric interference may hold the insert in place. In some examples, the insert may be attached to the main body with aid of an adhesive, fastener, soldering or melting, or the features may be directly formed within the main body.Docket No. 6826.001 WO1

[0126] FIG. 7B shows a cross-sectional view of a threaded insert 730, according to some examples. The insert may include one or more internal geometric features, such as threads, helix, spiral, or other shapes. The internal geometric features may be complementary to a shape of the corkscrew. The internal geometric features may include protruding portions 731 that may hug or come between turns of the corkscrew’. The corkscrew turns may fit into recessed portions 732 of the geometric features. The insert may be formed so that the corkscrew tightly fits with the geometric features, so that the corkscrew can not slip vertically past the protruding portions between the coils. The corkscrew must be rotated in order to allow for longitudinal motion of the corkscrew. The corkscrew may follow the recessed portions 732 of the geometric features in order to gradually turn and move upwards or downwards. In some examples, when a resistance falls beneath a resistance threshold level, the corkscrew may only move by rotating and moving longitudinally at the same time, due to the corkscrew geometry. When resistance falls above the resistance threshold level, the corkscrew may rotate in place without moving longitudinally. The internal features may be formed from a material that may have some flexibility to allow such motion when the resistance exceeds the resistance threshold level.

[0127] In some examples, the protruding portions 731 may protrude at least 0.1 mm, 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, or 5 mm relative to a recessed portion 732. The protruding portions and recessed portions may be arranged in a parallel slanted configuration around the internal surface of the insert. The angle of slant may match an angle of slant of the turns of the corkscrew. In some examples, the angle of slant may be less than or greater than an angle of slant of the corkscrew. In some examples, a single protruding portion 731 may fit between each adjacent turn of the corkscrew. In some examples, a plurality of protruding portions, such as two, three, four, or more protruding portions may fit between each adjacent turn of the corkscrews

[0128] FIG. 8A shows a cork extractor 800 with a main body 810 engaged with a beverage container 801, according to some examples. In some examples, the beverage container may be a wine bottle, such as 750 ml wane bottle. The cork extractor may be configured to open any type of bottle, including but not limited to soda bottle, milk bottle, beer bottle, split (187.5 ml) bottle, demie (375 ml) bottle, jennie 500 ml bottle, standard 750 ml bottle, magnum 1.5 LDocket No. 6826.001 WO1bottle, double magnum 3L bottle, or larger bottle. The cork extractor may be configured to remove a cork from any other type of beverage container as described elsewhere herein.

[0129] The main body 810 of the cork extractor may engage with the beverage container 801 by wrapping around a neck of the beverage container (e.g., bottle neck). A plurality of legs 812 may be positioned on different sides of the neck of the beverage container. A set of lip inserts 814 may be provided on the legs of the main body. In some examples, the main body may be rotated so that a cutter insert that is part of the lip inserts or below the lip inserts can cut a cover (e.g., paper, etc.) of the beverage container and remove the cover. In some examples other cutters which may be provided on the main body, or separate cutters may be used to remove the cover. Once the cover is removed, the lip inserts may rest on top of an upper surface of the beverage container, A portion of a cork 802 of the beverage container may or may not extend up out of the upper surface of the beverage container,

[0130] The mam body 810 may wrap around the beverage container neck and apply pressure via flexion. The legs 812 may squeeze together based on a natural bias of the legs. This pressure may be sufficient to hold the main body on the top of the beverage container independent from the user. In other instances, the legs may be manually squeezed together by being gripped by a user’s hand. The positioning of the main body 810 of the cork extractor may naturally center the corkscrew 820 helix relative to the cork 802.

[0131] A corkscrew 820 may include a helix. A handle 825 may be provided at a proximal end of the helix. A tip 826 of the helix may be configured to penetrate the cork. The corkscrew 820 may be movable relative to the main body 810. When a corkscrew is engaged with the mam body, an insert of the main body may be engaged with the corkscrew. The insert of the main body may prevent the corkscrew from slipping upwards or downwards on its own, absent a rotational force. If a user removes the user’s hand from the corkscrew, the corkscrew may remain at the same position relative to the main body without slipping on its own.

[0132] At an initial position, the tip 826 of the corkscrew may be located between the legs 812 of the main body 810. The tip may be arranged over the cork prior to penetrating the cork. The corkscrew 820 may have a relatively raised position relative to the main body 810

[0133] FIG. 8B shows a cork extractor 800 with a corkscrew 820 helix that is being inserted into a cork 802, according to some examples. In some examples, a main body 810 of the cork extractor may be stabilized relative to the beverage container 801. In some example, a user’sDocket No. 6826.001 WO1hand 803 may grasp the legs 812 of the main body to stabilize the main body. The legs may be squeezed together or squeezed around the beverage container 801.

[0134] A user may use another hand to grasp a handle 825 of the corkscrew 820. The handle may be rotated. In some examples, the handle may be rotated in a first direction. The first direction may be a clockwise or counterclockwise direction. The rotation of the handle may result in the corkscrew being driven downwards and rotated. An insert within the main body may engage with the corkscrew helix so that the user does not need to exert substantial downward force while the corkscrew is driven downwards. Rotational force may be sufficient to naturally cause the corkscrew to move downwards. This may allow for improved ease of use of the corkscrew while more precisely positioning the corkscrew, reducing the risk of damage to the cork. The corkscrew may be driven downwards until the tip of the corkscrew penetrates the cork 802.

[0135] In some exampl es, configurations of the insert, such as a tooth element with biasing mechanism, may allow the corkscrew to be pressed down quickly. The corkscrew helix may be pressed downward from the top to cause it to slide downward, as applying sufficient pressure may compress the spring and allow the helix to pass freely. In other examples, the downward force may not allow such translational motion, and translational motion may only occur in conjunction with rotation of the corkscrew. This may depend on the configuration of the tooth and the biasing force provided by the biasing mechanism.

[0136] While a knob-like handle 825 is illustrated, it can be appreciated that the handle can have a crank configuration as illustrated elsewhere herein, or any other configuration. A user may grasp a grip of a crank with the user’s hand and move the grip in a circle to cause the rotation of the handle, and the corresponding movement of the corkscrew.

[0137] FIG. 8C shows a cork extractor where the corkscrew 820 helix is further inserted into the cork 802, according to some examples. As the main body 810 is stabilized relative to the beverage container, the corkscrew 820 may be driven further into the cork 802. The grip from the insert may drive the corkscrew helix downward further into the cork as the handle 825 is rotated. As the corkscrew is being driven further into the cork, a distance h between a surface of the handle and an upper surface 206 of the mam body may be decreasing.

[0138] While the corkscrew is further penetrating into the cork 802, a user may continue holding the legs 812 of the main body 810 to keep the main body stable relative to the beverageDocket No. 6826.001 WO1container 801. In some examples, the pressure from the legs may be sufficient to keep the main body in place while the corkscrew is being driven into the cork.

[0139] FIG. 8D shows a cork extractor 800 where the corkscrew 820 helix is fully inserted into the cork 802, according to some examples. The corkscrew helix may be driven downwards by continuing to be rotated in the first direction. A user may rotate the handle to move the corkscrew downwards until the handle 825 contacts an upper surface 806 of the main body 810. In some examples, the distance h between the handle and the upper surface may be zero. While a handle and upper surface of the main body are described as contact surfaces that stop the downward motion of the corkscrew it can be appreciated that other contact surfaces can be provided between the corkscrew and the main body. The corkscrew' may no longer be driven downwards when a top of the corkscrew helix reaches an upper surface of the main body and cannot freely rotate further.

[0140] Up until the stoppage of the corkscrew from further descending, the corkscrew helix may have been in a penetrating mode, as it was spun further and further into the cork. While in the penetrating mode, the resistance on the corkscrew relative to the insert may be sufficiently low so as to not exceed a resistance threshold level. This may cause the insert to be engaged with the corkscrew helix in a manner that prevents slippage of the corkscrew. The corkscrew may only move rotationally and in the longitudinal direction together.

[0141] After the penetrating phase, the next phase may be an extracting phase. During the extracting phase, the cork may be removed from the beverage container. This may occur while no further vertical movement is possible by the corkscrew helix. This may be due to the limit imposed by the upper surface of the mam body of the cork extractor.

[0142] FIG. 8E shows a cork extractor 800 where the corkscrew 720 helix is rotated to begin removing the cork 802 from the beverage container 801, according to some examples. The corkscrew handle 825 may continue to be rotated in the first direction. As the corkscrew helix continues to correspondingly rotate in the first direction, with no vertical movement possible, a sufficient amount of force may be provided to allow slippage with respect to the insert. For example, a threshold resistance value relative to the insert may be exceeded, which may allow the corkscrew helix to rotate without moving vertically. This rotational motion may apply an upward force to the cork 802, allowing the cork to start lifting from the beverage container 801.Docket No. 6826.001 WO1

[0143] FIG. 8F shows the cork 802 is further removed from the beverage container 801, according to some examples. As the corkscrew handle 825 and corkscrew 820 helix continues to rotate in the first direction without moving upwards or downwards, the cork 802 may be further lifted out of the beverage container 801. In some examples, the lip inserts 814 or internal surfaces or features of the legs may come into contact with the cork to keep it from rotating relative to the main body 810 and / or the beverage container 801. In initial stages, frictional fit between the cork and an interior surface of the beverage container may prevent significant rotation between the cork and interior surface of the beverage container. Additional internal contact surfaces may not be required to prevent or reduce rotation of the cork.Preventing rotation of the cork may cause the cork to primarily translate upwards as the corkscrew helix is rotated.

[0144] FIG. 8G shows the cork 802 has been fully removed from the beverage container 801, according to some examples. The handle 825 of the corkscrew may be rotated until a bottom level of the cork clears the upper surface of the beverage container. The handle of the corkscrew may be rotated until the majority of the cork has cleared the beverage container. The handle of the corkscrew may be rotated until the friction force holding the cork to the beverage container is no longer strong enough to keep the cork within the beverage container. In some examples, a user may yank the cork extractor upwards to free the bottom portion of the cork from the beverage container. In some example, a user may not need to exert any vertical force to remove the cork from the beverage container, as the cork may be freed from the beverage container by the motion of the corkscrew helix. In some examples, the handle of the corkscrew may be rotated until an upper surface of the cork 802 come into contact with a lower surface of a central portion of the main body 810.

[0145] FIG. 8H shows the cork extractor 800 and the cork 802 that have been removed from the beverage container 801, according to some examples. After the cork 802 has been freed from the beverage container 801, the handle 825 and the corkscrew 820 may no longer need to be rotated. The cork extractor 800 including the main body 810 and the corkscrew 820 may be lifted off of the beverage container. The extracting phase of cork removal process may be complete.

[0146] In some examples, a user may manually grip the main body 810 of the cork extractor to keep it at a fixed position relative to the beverage container during the penetrating phaseDocket No. 6826.001 WO1and / or the extracting phase. In some examples, for one or more for the phases, a user does not need to grip the main body of the cork extractor to keep it in place. During the penetrating and / or extracting phase, the user may use a single hand to rotate the handle 825 in a first direction. The user may grasp the handle like knob, may turn a crank, or may provide any other motion that may result in rotation of the corkscrew.

[0147] Following a penetrating and extracting phase, a cork freeing phase may be provided. During the cork freeing phase, the corkscrew may be removed from the cork, separating the cork from the cork extractor.

[0148] FIG. 81 shows a force applied to the main body 810 to engage a gripping mechanism with the cork 802, according to some examples. The mam body may include a set of legs 812. The legs may flex relative to the cork and squeeze the cork between the legs. In some examples, a user may use a user’s hand 803 to grip one or more cork grips 816 that may be provided on the legs of the mam body. The cork grips may protrude outwards from an outer surface of the legs. The cork grips may be provided on flexible members that may move or flex relative to the rest of the legs 812. One or more gripping members, which may include pointed features or other features that may engage with the cork may be provided. The gripping members may be provided opposite the cork grips and may be driven into the cork when the cork grips are flexed together. In some examples, cork grips may not be provided, and user may squeeze together the legs 812 to grip the cork. The user may squeeze the distal ends of the legs or an intermediate portion of the legs. Inner gripping members may or may not be provided when the legs are squeezed together. In some examples, the inner surface of the legs may include a high friction material that may grip the cork when the legs are squeezed together.

[0149] FIG. 8J shows the corkscrew 820 helix is rotated to remove the corkscrew helix from the cork 802 while gripping mechanisms are engaged, according to some examples. A user may squeeze a portion of the legs of the mam body 810 together in order to continue gripping the cork. For example, a user’s hand 803 may be used to squeeze together a distal or intermediate portion of the legs of the main body. The user’s hand may squeeze cork grips together which may or may not be provided on flexible members. Squeezing the legs together may enable a grip on the cork that prevents substantial rotation of the cork. In some examples, surface features, such as pointed surface features, or surface materials may help prevent the cork from rotating while the legs are squeezed.Docket No. 6826.001 WO1

[0150] While a first hand 803 may squeeze the main body, a second hand may twist a handle 805 of the corkscrew in a second direction opposite the first direction. For example, if the first direction was clockwise, the second direction may be counter clockwise, or vice versa.Rotating the handle in the second direction may cause the corkscrew helix to withdraw from the cork, and the corkscrew may move upwards relative to the cork.

[0151] FIG. 8K shows the corkscrew 820 helix has been rotated to fully remove the corkscrew helix from the cork 802 while remaining engaged with the main body 810 of the cork extractor 800, according to some examples. As the handle 825 is rotated in the second direction, the corkscrew 820 helix may be withdrawn from the cork until the tip of the corkscrew helix is no longer penetrated into the cork. A gap 804 may be provided between the end of the corkscrew helix and the cork.

[0152] A user may grasp the mam body 810 of the cork extractor with the user’s hand 803 until the corkscrew 820 helix is free of the cork 802. At this point, the handle 825 may be raised high above the main body 810 of the cork extractor 800. An insert within the mam body 810 of the cork extractor may keep the corkscrew stabilized relative to the mam body, even if the user is no longer holding the corkscrew or handle of the corkscrew.

[0153] FIG. 8L shows the cork 802 that has been separated from the cork extractor 800, according to some examples. After the corkscrew 820 helix has been withdrawn from the cork 802, a user may no longer need to turn the handle 825 of the corkscrew. A user may no longer need to squeeze the main body 810 of the cork extractor 800 in order to keep the cork in place. The cork 802 may be removed from the mam body 810 of the cork extractor 800.

[0154] The cork extractor and methods of use described herein may advantageously allow a user to center the corkscrew within the cork and easily remove the cork without exerting substantial force. The cork may be removed from a beverage container without damaging the cork, or leaving bits of cork within the beverage container. The penetrating phase where the insert engages the corkscrew may allow the corkscrew to cleanly enter a center portion of the corkscrew without damaging the corkscrew. The extracting phase may allow the corkscrew to continue to be rotated, automatically causing the cork to be lifted out of the beverage container without damaging the cork. The cork freeing phase allows the corkscrew to be cleanly removed from the cork.
