Abstract
A tap (1) is disclosed for delivering liquids, particularly for delivering high- and medium-density liquids from rigid vessels, comprising: a body (3); stem means (9); and elastic actuating means (11) of the stem means (9); air inlet/outlet means (13, 25, 28) in the body (3) and inside the vessel; valve means (7) for passing air; non-return valve means (26) placed between the air inlet and outlet means (13, 25, 28) and the vessel interior and adapted to be guided and driven by the pressure difference between outside the tap (1) and inside the vessel; anti-counterfeiting and protecting means (A); supporting means (E); and an integrated glass (D).
Claims19
A tap for delivering liquid, the tap comprising:
- a body equipped with a connection part to a vessel of liquid to be delivered and with a liquid delivering passage, the connection part including an internal sealing cylinder, and the body including an air chamber;
- stem means adapted to open and close the liquid delivering passage;
- elastic actuating means adapted to actuate said stem means in their delivery opening and closing positions;
- air inlet and outlet means in the body and inside the vessel;
- valve means adapted to open and close an air passage in said air inlet and outlet means;
- an air duct placed in said body between said internal sealing cylinder of the connection part and said air chamber;
- non-return valve means placed in said body between said air inlet and outlet means and a vessel interior, and said non-return valve means placed entirely upstream of the internal sealing cylinder, said non-return valve means being adapted to be guided and driven by a pressure difference between outside the tap and inside the vessel;
- a first engaging element with anti-counterfeiting and protecting function;
- a second engaging element with anti-counterfeiting and protecting function, adapted to operate with a plane obtained on the body to determine a correct positioning of the tap on the vessel;
- a first small flexible lip adapted to block the tap;
- and
- a third engaging element with anti-counterfeiting and protecting function, shaped as a second small flexible lip at 180° from the first small lip, adapted to engage an external side of the first engaging element, generating a combination of forces which performs the anti-counterfeiting and protecting function.

A tap configured to be connected to a vessel containing liquid, the vessel including a vessel interior, the tap comprising:
- a body including a connection part with a liquid delivering passage, the connection part including an internal sealing cylinder, and the body including an air chamber;
- a stem adapted to open and close the liquid delivering passage;
- an actuating member adapted to actuate the stem to a delivery opening position or a delivery closing position;
- an air hole in the body;
- a valve adapted to open and close an air passage in the air hole;
- an air duct disposed in the body between the internal sealing cylinder of the connection part and the air chamber;
- a non-return valve in the body disposed between the air hole and the vessel interior, and the non-return valve disposed entirely upstream of the internal sealing chamber, the non-return valve being adapted to be guided and driven by a pressure difference between outside the tap and inside the vessel;
- a first engaging element;
- a second engaging element adapted to operate with a plane obtained on the body to determine a correct positioning of the tap on the vessel;
- a first small flexible lip adapted to block the tap;
- and
- a third engaging element shaped as a second small flexible lip, the third engaging element adapted to engage an external side of the first engaging element to generate a combination of forces which perform an anti-counterfeiting and protecting function.

A system for delivering liquid, comprising:
- a vessel including a vessel interior adapted to contain a liquid;
- and
- a tap including:
- a body including a connection part with a liquid delivering passage adapted to connect to the vessel, the connection part including an internal sealing cylinder, and the body including an air chamber;
- a stem adapted to open and close the liquid delivering passage;
- an actuating member adapted to actuate the stem to a delivery opening position or a delivery closing position;
- an air hole in the body;
- a valve adapted to open and close an air passage in the air hole;
- an air duct disposed in the body between the internal sealing cylinder of the connection part and the air chamber;
- a non-return valve in the body disposed between the air hole and the vessel interior, and the non-return valve disposed entirely upstream of the internal sealing cylinder, the non-return valve being adapted to be guided and driven by a pressure difference between outside the tap and inside the vessel;
- a first engaging element;
- a second engaging element adapted to operate with a plane obtained on the body to determine a correct positioning of the tap on the vessel;
- a first small flexible lip adapted to block the tap;
- and
- a third engaging element shaped as a second small flexible lip, the third engaging element adapted to engage an external side of the first engaging element to generate a combination of forces which perform an anti-counterfeiting and protecting function.
