Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a device for opening bottles with natural corks, and preferably bottles of sparkling wine. The bottle opening device may include a bottle rest to be laterally pushed onto a neck of the bottle to encircle a mouth of the bottle on three sides and from above and below. The device may also include a holding tongue formed from the bottle rest to rest against the neck of the bottle, and a cork holder to hold a head of a cork on three sides and from above and below. The cork holder may be movably mounted in the bottle rest to perform a lifting motion relative to the bottle rest. The device may also include a lever pivotably mountable to the bottle rest to move the cork holder relative to the bottle rest. The cork holder can be pivoted around a rotational axis of the bottle rest at an upper end of a lifting motion. The rotational axis may be positioned to run substantially perpendicular to an axis of the bottle and may be positioned eccentrically at a level of a bottle opening. The lever may include a stop mechanism to stop the cork holder at the upper end of the lifting motion, and the lever may include a curved deaeration track arranged such that when the lever may be moved to rotate the cork holder around the rotational axis of the bottle rest under the pressure of the cork.

2. Discussion of the Background Information

Numerous devices substantially similar to the devices generally described above are known in the prior art.

For example, in U.S. Pat. No. 2,761,338 a device is shown in which a holder is pushed laterally onto the neck of a bottle. U.S. Pat. No. 4,527,450 shows a device which can be pushed laterally onto the head of the cork jutting out of the bottle. In this manner, the cork is pulled out by via of a pulling lever. European Patent Publication 0 164 955 describes device with which a cork is removed from the bottle via a pivoting lever mounted on a part that holds the bottle. Finally, in European Patent Publication 0 291 546 a device is known which is similar in general to the features of the present invention.

In accordance with the prior art devices, a cork may be extracted or removed from a bottle. However, these devices suffer certain disadvantages in that they cannot open a bottle in a controlled fashion. That is, according to the pressure and temperature, the cork is released with a greater or lesser explosion. When the bottle contains, e.g., sparkling wine, the explosion of the cork removal also releases much of the "carbon dioxide" found in the sparkling wine. In this manner, the contents of the bottle generally ends up foaming over adversely affecting the taste of the wine.

SUMMARY OF THE PRESENT INVENTION

The present invention provides a device to open bottles having natural corks so as to reduce the pressure in a controlled fashion. Thus, the present invention provides a cork holder, i.e., a component to hold the cork, that may be pivotably rotated around a rotational axis of a bottle rest, i.e., a component to hold the bottle, at an upper end of a lifting motion. The rotational axis may run substantially perpendicular to the bottle axis and may be eccentrically mounted at a level of a bottle opening. The lever may have a stop mechanism to stop the cork holder at the upper end of the lifting motion, and the lever may include a curved deaeration track positioned to rotate the cork holder around the rotational axis of the bottle rest under the pressure of the cork.

The advantages to the device of the present invention are evident in, e.g., that bottles with natural corks can be opened easily, that an explosion of the cork and thus a sudden release of the "carbon dioxide" contained in the wine may be avoided, and that the device is very simple and comfortable to use.

The present invention is directed to a device for opening bottles with natural corks. The device may include a bottle rest to be laterally positioned around a neck of the bottle to encircle a mouth of the bottle on three sides and from above and below the mouth, a holding tongue downwardly extending from the bottle rest adapted to be positioned adjacent the bottle neck, and a cork holder to hold a head of the cork on three sides and from above and below the head of the cork. The cork holder may be movably mounted in the bottle rest, and a lever may be rotatably mounted to the bottle rest, such that rotational movement of the lever provides relative movement between the bottle rest and the cork holder. The cork holder may be pivotably mounted around a rotational axis of the bottle rest at an upper end of a lifting motion, such that the rotational axis runs perpendicular to a longitudinal axis of the bottle and is positioned eccentrically at a level of a bottle opening. The lever may include a stop mechanism to define the upper end of the lifting motion and a curved deaeration track arranged such that, during rotation of the lever, the cork holder rotates around the rotational axis under the pressure of the cork.

In accordance with another feature of the present invention, the lever may further include a substantially u-shaped yoke having two substantially parallel plate-shaped ends. The substantially parallel plate-shaped ends may include the stop mechanism and the curved deaeration track and further may include a curved lifting track to raise the cork holder with respect to the bottle rest, and a curved guiding track to pivot the cork holder to a final open position. Further, the curved lifting track, the stop mechanism, the curved deaeration track, and the curved guiding track may be arranged to merge together to form a single continuous groove. When the cork is pulled up, a force applied to the lever a substantially vertically downward force, and a deaeration of the bottle and removal of the cork occur by moving the lever in an opposite direction.

In accordance with a further feature of the present invention, the stop mechanism may include a cylindrical peg coupled to the cork holder and the curved deaeration track may include a wavy profile having interior radii approximately corresponding with a radius of the cylindrical peg.

In accordance with still another feature of the present invention, the cork holder may be mounted to the bottle rest with at least two bolts and at least one of the at least two bolts mount the lever to the bottle rest. Further, the at least two bolts may include at least one upper bolt and at least one lower bolt, and the at least one of the at least two bolts mounting the lever to the bottle rest being the at least one upper bolt. Alternatively, the at least two bolts may include two upper bolts and two lower bolts, and the at least one of the at least two bolts mounting the lever to the bottle rest being the two upper bolts.

In accordance with another feature of the present invention, the device may be positionable in a closed position by pivoting the lever into a position substantially parallel to the holding tongue.

In accordance with still another feature of the present invention, the device may also include at least one pulling spring positioned between the bottle rest and the cork holder. The at least one pulling spring may bias the cork holder to abut the bottle rest at a beginning of the lifting motion, may bias the device into an open position after extraction of the cork, and may bias the device into a closed position when closed.

In accordance with a further feature of the present invention, the cork holder may include a curve to facilitate removal of the cork.

In accordance with still another feature of the present invention, the bottle may contain sparkling wine.

The present invention may also be directed to a device for removing a cork from a bottle. The bottle may have a neck and an opening within a mouth portion of the bottle located at an end of the neck. The device may include a bottle rest that is positionable around at least a portion of the mouth portion, and a cork holder that is positionable around at least a portion of the cork. The cork holder may be movably coupled to the bottle rest for rotational and axial movement with respect to the bottle rest. The device may also include a lever coupled to the bottle rest and the cork holder for selectively moving the cork holder one of axially relative to the bottle rest and angularly relative to the bottle rest. The lever may include a stopper mechanism to restrict the axial movement of the cork holder relative to the bottle rest and further include an aerating track for angularly guiding the cork holder relative to the bottle rest.

In accordance with another feature of the present invention, the stopper mechanism and the aerating track may be arranged such that the lever is moved in opposite directions to effect the axial movement and the angular movement of the cork holder relative to the bottle rest.

In accordance with another feature of the present invention, the device may also include a holding tongue extending from bottle rest to stabilize the device during use.

In accordance with a further feature of the present invention, the lever may also include a lifting track arranged to effect axial movement of the cork holder relative to the bottle rest from a position in which the cork holder and the bottle rest are in contact to a point defined by the stop mechanism. Further, the device may include at least one peg coupled to the cork holder and engaging with the lifting track. The lifting track and the deaerating track may be coupled together.

In accordance with a still further feature of the present invention, the device may also include at least one peg coupled to the cork holder and engaging the deaerating track.

In accordance with still another feature of the present invention, the device may include at least one pulling spring for biasing the cork holder and the bottle rest toward each other.

In accordance with another feature of the present invention, the lever may also include a curved track for placing the device in a closed position.

In accordance with a further feature of the present invention, the deaerating track may include a wavy profile for controlling deaeration of the bottle.

DETAILED DESCRIPTION OF THE INVENTION

The particulars shown herein are by way of example and for purposes of illustrative discussion of the present invention only and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the invention. In this regard, no attempt is made to show structural details of the invention in more detail than is necessary for the fundamental understanding of the invention, the description taken with the drawings making apparent to those skilled in the art how the several forms of the invention may be embodied in practice.

As shown in FIGS. 1-6, the bottle opening device in accordance with the present invention includes a bottle rest 1, a cork holder 2, and a lever 3 that may be connected by two bolts 4 and 5. At least one pulling spring 6, which may initially hold the opening device in a starting position, may be suspended between bottle rest 1 and cork holder 2.

Bottle rest 1 may include a c-shaped curve la conformed to fit, e.g., a diameter and cross-section of the bottle. In this manner, bottle rest 1 may be laterally slid or pushed from its open side onto the mouth of a wine bottle. A cross-sectional contour of curve 1a may be formed such that mouths of commercially available bottles of champagne and sparkling wine may be held on an upper and lower surface or portion of the bottle mouth. To facilitate placement of bottle rest 1 on the mouth of the bottle, guiding bevels 1b may be formed on the open side of curve 1a. Guiding bevels 1b may also be utilized for retaining the upper and lower portions of the bottle mouth.

On a closed side of c-shaped curve 1a, a holding tongue 1c may be formed to extend downward from bottle rest 1. Holding tongue 1c may be formed to preferably follow a curve of a neck of the bottle and to rest against the curve.

A length of holding tongue 1c may be selected such that it may ends in an area in which the neck of the bottle has yet to be sharply curved.

Two substantially vertically parallel holders 1d may be positioned on the lateral sides of bottle rest 1, i.e., adjacent the open and closed sides of c-shaped curve 1a. Each parallel holder 1d may include a lower hinge point 1e and an upper hinge point 1f.

Between parallel holders 1d and an interior portion of c-shaped curve 1a, two substantially vertical openings 1g may be formed. Further, two vertical tongues 2a of cork holder 2 may engage openings 1g such that, in a starting position, a lower horizontal surface 2b may rest against or abut an upper horizontal surface 1h of bottle rest 1 in a vicinity of c-shaped curve 1a.

Above resting surface 2b, which may rest exactly on an upper edge of the mouth of the bottle being opened and under the head of the cork, cork holder 2 may also have a c-shaped curve 2c which may sit axially over curve 1a of bottle rest 1. Further, curves 1a and 2a may be positioned such that their open ends may be directed toward a same side, and their diameters and cross-sections may be formed to enable cork holder 2 to be laterally slid or pushed onto the head of the cork in the bottle. In this regard, cork holder 2 may also include guiding bevels 2d located on the open side of curve 2a so as to facilitate placement of cork holder 2.

Cork holder 2 may be rigidly mounted in bottle rest 1 via bolts 4 and 5 at hinge points 1e and 1f. Bolts 4 and 5 may be pointed inward so that they can slide back and forth in sliding guide tracks 2e, 2f, and 2g of vertical tongue 2a.

Sliding guide tracks 2e and 2f may extend substantially vertically and may be of a same length. At a lower end of guide track 2f, an arc-shaped guide track 2g may be formed to include a center that lies within the lower hinge point of guide 2e.

In an upper rear area of c-shaped curve 2c of the cork holder, a semi-circular opening 2h may be formed to approximately correspond sizewise with a thumb. This facilitates removal of the extracted cork from the cork holder.

Cork holder 2 may be moved across bottle rest 1, e.g., via cylindrical pegs 2i which laterally extend outward from cork holder 2 and extend along an axis through and over parallel holders 1d. Accordingly, holders 1d may be recessed in a vicinity of motion of pegs 2i.

Pegs 2i may laterally engage with a curved section of a plurality of guiding tracks of lever 3. Lever 3 may be a substantially u-shaped arch and may be rotatably secured at hinge points 1f. The plurality of guiding tracks of lever 3 are positioned outwardly adjacent holders 1d in a plate-shaped and substantially parallel arrangement.

The plurality of curved guiding tracks arranged in the plates of lever 3 may be axially aligned and may include a curved lifting track 3a, a stop mechanism 3b, a curved deaeration track 3c, a curved guiding track 3d, and a curved track 3e. Tracks 3a-3e may be incorporated into a single curved guide track.

Between bottle rest 1 and cork holder 2, and alongside c-shaped curves 1a and 2a, at least one pulling spring 6 may be suspended to selectively hold the opening device in starting position, in a final open position, or in a closed position. The specific position being selected in accordance with a specific position of the lever.

In an exemplary manner, the opening device of the present invention may be stored in the closed position, as illustrated in FIG. 8. In the closed position, pegs 2i may lie in curved track 3e and lever 3 is located in a substantially parallel position to holding tongue 1c. In this arrangement, pulling spring 6 holds the opening device in the closed position with a pulling force.

To operate the opening device, lever 3 is pulled outwardly, i.e., away from holding tongue 1c, so that pegs 2i slide along curved track 3e and, due to the force of pulling spring 6, slide into curved lifting track 3a until reaching the stopping point 3f, as shown in FIG. 1. The opening device is now in the starting position, the surfaces 1h and 2b are positioned adjacent and in contact with each other, as shown in FIG. 3. In this position, the opening device may be laterally pushed onto a bottle with a cork.

When operating the opening device, the user should grip the neck of the bottle with one hand such that holding tongue 1c is firmly enclosed. That is, the opening device is inserted around the bottle and cork until holding tongue 1c is positioned adjacent the bottle neck.

In the starting position, lever 3 may preferably extend upward at a small angle above the horizontal and the user may easily press lever 3 downward with the other hand. Due to the substantially flat curvature of curved lifting track 3a, i.e., with respect to a direction of motion of the cork holder 2, cork holder 2 and the cork may be released from the starting position under light pressure. As the counter pressure of the cork increases, lever 3 may be depressed more and more easily until the force, due to the shape of the cork portion inserted within the bottle neck, is reversed and the cork is pushed out of the bottle by the internal pressure within the bottle. Lever 3 may be continually be moved downward until pegs 2i come out of, or exit, curved lifting track 3a and come to rest on stop mechanism 3b arranged radially to rotation point 1f. In this position, as illustrated in FIG. 6, cork holder 2 is in its uppermost position at stop mechanism 3b. A safety edge 3g prevents lever 3 from being pressed further downward. The position of safety edge 3g may be calculated or determined so as to prevent the user's hand from being pinched between lever 3 and the bottle.

Finally, to completely uncork the bottle, the bottle should be deaerated. In this embodiment, curved deaeration track 3c extends from stop mechanism 3b so that deaeration may occur by pressing or moving lever 3 in an opposite direction, i.e., upward and away from the bottle. In this manner, pegs 2i may enter curved deaeration track 3c due to the upward pressure exerted by the cork. Curved deaeration track 3c may be arranged to become radially narrower in a direction of lever rotation point 1f. Thus, while lever 3 is being pressed or moved, cork holder 2 may be turned around or rotated about its rotational axis le under the pressure of the cork. The cork may be pushed over the edge of the bottle opening, and may be released on an opposite side thereof, as illustrated in FIG. 7. In this manner, the pressure within the bottle is released.

The more slowly and sensitively the deaeration process is performed, the more the air can be released in a controlled fashion.

To assist in providing a slow and controlled deaeration, curved deaeration track 3c may include a wavy profile 3h having interior radii approximately corresponding to a radius of pegs 2i. Pegs 21 may be moved from crest to crest and the bottle can be slowly deaerated in a steady controlled manner. When the bottle is completely deaerated, the lever is pressed or moved frther until curved guiding track 3d pivots cork holder 2, and the retained cork, away from the bottle opening into the final open position shown in FIG. 7. In this final position, pulling spring 6 holds the opening device in this position so that the opening device may be detached from the bottle and so that the cork can be removed from cork holder 2. The device may then be returned to the closed position and stored until its next use.
