[0034] With particular reference to the figures, a device to extract the cap 100 of a bottle 102, for example of sparkling wine and/or champagne, is globally indicated with 1.

[0035] Said device 1 is of the type comprising a casing 2, with substantially truncated-conical shape.

[0036] Said casing 2 is adapted to house a mushroom-shaped cap 100, and an ejection system 3 for the cap 100, coaxial to the cap 100 itself, placed on the top 2a of said casing 2.

[0037] The device 1 has a truncated-conical shape so that when it is in a work or engagement position B, a lower base 20b thereof, arranged towards the bottle 102, has a diameter greater than an upper base 20a thereof arranged towards the top 2a of said casing 2 and the top of the cap 100.

[0038] The device 1 also comprises two lever-type locking means 4, placed specularly in two seats 2b present on the side surface of the casing 2, rotating and pivoted to said casing 2.

[0039] Said locking means 4 are adapted to assume an engagement position B in which said locking means 4 engage with the cap 100 to lock it inside the casing 2 and facilitate the extraction thereof.

[0040] In particular, each locking means 4 comprises an arm 4a of said lever, protruding vertically with respect to said casing 2, to allow and facilitate a manual intervention during the step of inserting the casing 2 around the cap 100; each locking means 4 can furthermore comprise at least one pin 6 preferably placed near a lower end 5 of each locking means 4; said pin 6, acts as a rotation fulcrum and is adapted to engage in a concave space 7 of the seat 2b of the casing 2 and around which the locking means 4 itself rotates.

[0041] Said locking means 4, as the name itself implies, have the function of locking the cap 100 inside the casing 2 when the latter is placed above the bottle 102.

[0042] This function of locking the cap 100 inside the casing 2 will be described in more detail below.

[0043] Since said two locking means 4 are completely identical, for simplicity's sake, only one of the two will be referred to below.

[0044] A locking means 4, therefore, can summarily comprise:

[0045] said arm 4a protruding above said casing 2;

[0046] a work surface 4b protruding towards the inside of the casing 2; said surface 4b being concave and shaped so as to adhere to the head 101 of the cap 100 and comprising a knurling 4c that generates friction and improves the grip of the device 1 on the cap 100; said work surface 4b comprises a side profile 4d that is inclined so as to be convergent towards the inside and towards the lower base 2b of the casing 2, when the locking means 4 are in the engagement position B;

[0047] said pin 6, preferably placed below the surface 4b, preferably near a lower end 5 and adapted to engage in a concave space 7 present in each seat 2b of the casing 2 and around which each locking means 4 rotates.

[0048] Any constructive variants are considered to fall within the same scope of protection.

[0049] For example, a design form not depicted in the figure, can provide a device 1 with locking means 4 comprising the arm 4a that works with a lever opposed to that depicted in the figures, that is, the arm 4a rotates around a pin 6 or fulcrum placed above the surface 4b and with the pressing part, adapted to be grasped with the hand, placed below said rotation fulcrum or pin 6.

Preferably, the parts of the locking means 4 facing outwards of the device 1 are shaped so as to increase friction with the hand of a user, in particular with vertical strips 4f arranged side by side and protruding.
Preferably, the arm 4a protrudes above said casing 2 by a height of at least 10 mm, preferably between 10 and 40 mm, preferably 20 mm.
Preferably, the knurling 4c comprises a so-called diamond shape.
In particular, the diamond shape comprises a plurality of protrusions preferably with pointed shape. Said protrusions are preferably arranged according to parallel rows vertically and/or horizontally adapted to form a matrix of protrusions on the surface 4b.

[0050] Said ejection system 3 for the cap 100 comprises a cap-pushing cylinder 9, coaxial to the cap 100 itself and placed on a top 2a of said casing 2. Said cylinder 9 consists of a hollow tubular body 10 and of a head 11 (of larger diameter than the tubular body 10).

[0051] As shown in FIG. 5, said hollow tubular body 10 ends, on the side opposite the head 11, with a plurality of teeth 12 each having a shoulder 13.

[0052] Said teeth 12 ensure that the pin 9, during assembly of the device 1, is easily insertable (and removable) inside a through hole 16 present in a recess 15 on the top 2a of the casing 2.

[0053] As can be seen in the figures, the shoulder 13 retains a sealing element 14, by way of example an O-Ring, which, during the step of ascent of the pin 9, corresponding to the insertion of the cap 100 inside the casing 2, prevents the removal of the pin 9 itself through the through hole 16.

[0054] It should be noted that, during the ascent step, the pin 9 is kept in the guide by a lead-in 17 present below the through hole 16 in the side underlying the top 2a of the casing 2.

[0055] In particular, said locking means 4 have two main positions:

[0056] one of insertion (A), in which the cylinder 9 is partially outside the casing 2 and the locking means 4 have the upper ends 4e spread apart; in this configuration, the surface 4b comprising the knurling 4c is at the height of the head 101 of the cap 100;

[0057] one of engagement (B) in which, the cylinder 9 is at its maximum exposure outside the casing 2 and the locking means 4 again have the arms 4a approaching; in this configuration, the surface 4b wraps the head 101 of the cap 100 with the knurling 4c.

[0058] Advantageously, said work surface 4b with knurling 4c allows the head of the cap to be gripped optimally and to prevent the casing 2 from slipping during the step of uncorking the bottle 102.

[0059] Preferably, between one seat 2b and the other one, the casing 2 has ergonomic grips 2c for the user's hand.

[0060] Operationally, the user wishing to uncork a bottle 102 bearing a cork 100 with a mushroom-shaped head 101, like for examples bottles 102 of sparkling wine and/or champagne, places the device 1 above said bottle 102 so as to insert the head 101 of the cap 100 inside the casing 2. In doing so, the ejection system 3 lifts up pushed by the cap 100 itself, and the locking means 4 rotate in their seat 2b around the cylinders 6 moving into the insertion position (A).

[0061] By continuing the operation of inserting the device 1 on the cap 100, the locking means 4 place themselves in the engagement position (E).

[0062] At this point, the user, by applying with one hand a force F on each locking means 4, causes the arms 4a to approach each other and the knurling 4c to engage against the head 101 of the cap 100 tightening it stably inside the casing 2.

[0063] Finally, by applying a rotation to the device 1 together with a vertical translation away from the bottle 102, the user is able to extract the cap 100 from the neck of the bottle 102.

[0064] Finally, in order to extract the cap 100 from device 1, the cylinder 9 is lowered, holding the rest of the device 1 in place.
