Description: DESCRIPTION CORKSCREW THAT EXTRACTS SIMULTANEOUSLY WITH THE CORK A PREVENTIVELY CUT PORTION OF THE CAPSULE ON THE NECK OF THE BOTTLE. Technical Field My invention relates to a corkscrew that extracts simultaneously along with the cork a preventively cut portion of the capsule on the neck of the bottle. This solution is conveniently applicable to open bottles which corks are covered with a capsule. Background Art In prior art are known corkscrews and are known also devices that cut the capsule that covers them. In particular: - corkscrews with an extraction screw that screw axially in the cork, involving means that consent the axial extraction are known. - there are also known devices that cut the upper portion of the capsule to remove it and take away the cork (US-786892; EP0220850). These devices if integrated in only one device (DE-839319; FR- 8200828) can operate only by means of two separate extraction operations, i.e.: - firstly, to cut and take away the upper portion of the capsule and then , - extract the cork. In fact, these last devices have at one end the screw means to extract the cork and at the other, the means to cut and extract the capsule. Disclosure of Invention The aim of this invention is to avoid said inconveniences. This and other aims are reached with this invention as claimed, by means of a corkscrew that extracts simultaneously along with the cork also a preventively cut capsule portion on the neck of the bottle, characterized in that it comprises coaxially with the extraction screw of the cork, an element equipped with a means for cutting towards the interior, that can be clamped around the neck of the bottle and rotated before, after or during the screwing: - to cut the coverage capsule of the cork from the neck of the bottle and - extract it directly with the same cork. With this solution we obtain the advantage of cutting the capsule and extracting the cork with only one operation, during the same extraction phase of the cork with the further advantage that the cut capsule portion rests directly encapsulated on the extracted cork. The invention is better understood with the enclosed description and data supplied for example only, in which: Figure 1 represents a schematic view of one of the many forms to use corkscrews with a lever which cut the capsule with a clamping means of conic coupling. 1 Figure 2 represents an alternative schematic view of a system of 2 clamping by means of a ring with a lever for tightening. 3 Figure 3 represents a view of a corkscrew simplified with a cutting 4 device with levers for clamping manually. 5 6 Referring to the Figures it is disclosed that: 7 - with 1 is indicated the extractor screw ensemble; 8 - with 2 the guide means and abutment to react to the extraction 9 force of the screw. I 0 According to invention the cutting device is substantially associated I I to this second element in order that, after screwing a part of the 1 2 screw in the cork and clamping, by means of the rotation of the 1 3 abutment guide and cutting means, we have the cutting of the 1 4 capsule by its rotation and then with the extraction of the cork the 5 cut capsule portion is extracted along with the respective cork. 6 On the basis of Figure 1 is illustrated a classic corkscrew with a lever 7 screw 1 supporting a toothed portion 12 and at one end, a screw for 8 screwing 13 inside cork 5 in the neck of bottle 4 covered by capsule 9 6. 0 The screw is moved axially by a pair of force levers 22 by means of 1 the toothing 21 on a guide compass and reaction 2 that extends 2 down with a tube to connect cork 16 and abutment and with free 3 elastic wings extending downwards towards the lower 23 supporting 4 idle rotating cutting wheels 24 and over this is brought an axially 5 sliding, conic coat 31 supporting two lower elastic guide arms 32, in 6 order to push, if lowered, the elastic wings towards the interior and 7 then the wheels 24 against the capsule 6 of the bottle in order to 8 rotate compass 2 and obtain the annular cutting of the capsule. This conic coat (31) allows the elastic fins (23) to scroll inside of it and to rotate freely even if clamped by the same coat against the neck of the bottle, favouring also automatic screw centering. Said rotation is made automatically by the eccentric peg 11 that when the screw 13 is almost completely screwed inside the cork 5, it engages with compass 2 making it rotate and therefore cut the capsule. After this it is sufficient to use the levers 22 lowering them in order to extract the cork (5) and the cut capsule portion (6). To facilitate the rotation we can provide also an annular thrust- bearing abutment at the basis of the connecting tube of cork 16 in order that this rests on the neck of the bottle (not illustrated). The clamping of the little cutting wheels 24 can be made also by means of the elastic ring 25 clamped by lever 25' or other equivalent means as indicated in Figure 2. In a simplified form the corkscrew includes, as indicated in Figure 3, the extractable screw 1 in a compass-support 2 accomplished by means of the pivoting 2c of two arms with foldable wings 23 having an abutment 23' and under this the little cutting wheels 24 (Fig.3 ). In this way we simply fold the wings 23 on the neck of the bottle and we clasp manually to press the wheels on the external part of the capsule, and with a rotating action they cut the capsule, after that the cork is extracted with screw 1 by the simple action of screwing . The advantage of having the openable arms (23) is that they facilitate the extraction of the cork and capsule portion by the screwing of the corkscrew. With occurred extraction the two arms of the compass (23) are opened for the extraction of the cork with the capsule portion. Obviously said cutting means (24) can be also not rotatable cutters or also knurled steel wire annularly clamped around to the neck of the bottle. We have illustrated two manual solutions but is evident that the system can be adopted also in motored solutions.
