The present invention relates to a technical cap (1) for bottles (2) for fizzy
wine or sparkling
wine refermented in
bottle, comprising: a
capsule (3), inside which a first cavity (4) is defined, having an at least partially substantially cylindrical conformation, comprising a first lateral surface (5) in which there is a first access opening (6), in f luid communication with a substantially cylindrical chamber (7) of said
capsule (3), designed to accommodate an open end (8) of the neck (9) of a
bottle (2) and to be hermetically fixed to the same by hermetic fixing means (10, 13) of a such technical cap (1), the first cavity (4) being also accessible through a, substantially cylindrical, access hole ( 14 ), obtained coaxially with the first cavity (4); - a
shutter (16), inserted into the first cavity (4) through the access hole (14) in such a way as to hermetically close the latter, wherein the
shutter (16) comprises an operating portion (17), comprising a second lateral surface (18), facing the first lateral surface (5) of the first cavity (4), in which a second access opening (19) to a second cavity (20), obtained inside the
shutter (16), is obtained, wherein the shutter (16) is rotatable inside the first cavity (4), around a medium cylindrical axis (15) of said first cavity (4), between a collection position thereof, in which the second access opening (19) faces the first access opening (6), and a storage position thereof, in which the second access opening (19) faces a first closed region (21) of the first lateral surface (5) of the first cavity (4), so as to be hermetically closed by it, and a second closed region (22) of the second lateral surface (18) faces the first access opening (6), so as to hermetically close it.
