         2 . The pourer according to  claim 1 , wherein the pourer further comprises a first non-return valve which is at the liquid flow channel and is configured to permit the liquid to flow via the first non-return valve towards the outflow direction when the pourer is at the pouring position, and inhibit the liquid to flow via the first non-return valve in the direction opposite the outflow direction when the pourer is at a resting position. 
     
     
         3 . The pourer according to  claim 2 , wherein the first non-return valve is a check ball valve, comprising a ball which is made of a copper alloy and/or is silver anodized. 
     
     
         4 . The pourer according to  claim 1 , wherein the first portion is helicoidal and/or the second portion is helicoidal. 
     
     
         5 . The pourer according to  claim 1 , wherein the pourer comprises a tube which forms the third portion of the liquid flow channel, a length of the tube being at least three times larger than a diameter of the tube. 
     
     
         6 . The pourer according to  claim 1 , further comprising a protector which comprises an opening through which passes the third portion of the liquid flow channel;
 wherein an end of the third portion is located on a first side of the protector;   the filter is located on a second side of the protector, the second side being opposite the first side;   the protector is configured to cover and protect the filter from the liquid which exits the end of the third portion when the liquid flows via the third portion in the outflow direction.   
     
     
         7 . The pourer according to  claim 6 , comprising a cap receptor which is attached to the filter and to the protector and comprises a cylindrical wall;
 the pourer comprises a chamber formed between the filter, the protector and the cylindrical wall;   the cylindrical wall comprises openings configured to allow air to flow through the openings towards the chamber and the filter;   the cylindrical wall comprising a screw thread configured for the screwing thereon of a screw cap.   
     
     
         8 . The pourer according to  claim 1 , further comprising a second non-return valve which is at the air intake channel and is configured to permit the air to flow via the second non-return valve towards the inflow direction and inhibit a flow of the liquid via the second non-return valve towards a direction opposite the inflow direction and towards the filter when the pourer is at the pouring position. 
     
     
         9 . The pourer according to  claim 8 , wherein the second non-return valve is a duck bill valve. 
     
     
         10 . The pourer according to  claim 1 , further comprising;
 an adaptor configured to be firmly attached to an opening of the container;   an intermediate part configured to be firmly attached to the adaptor such that at least part of the intermediate part is surrounded by the adaptor;   the intermediate part comprising a peripheral wall;   a central part configured to be firmly attached to the intermediate part such that at least a part of the central part is surrounded by the peripheral wall of the intermediate part;   the first portion and the second portion of the liquid flow channel are at least partially formed by an open space between the peripheral wall and the part of the central part surrounded by the peripheral wall of the intermediate part.   
     
     
         11 . The pourer according to  claim 10 , wherein:
 the central part comprises a tube, two helicoidal protrusions which protrude from and around a first portion of a wall of the tube, and a disc shaped protrusion which protrudes from the wall of the tube between the first portion and a second portion of the wall of the tube;   a first end of the tube is closed;   the tube comprises a first opening at the first portion of the wall of the tube, and a second opening at a second end of the tube opposite the first end;   the tube forms the third portion of the liquid flow channel, and said third portion extends from the first opening to the second opening;   the first opening connects the third portion to the second portion of the liquid flow channel;   at least a part of the first portion of the liquid flow channel and at least a part of the second portion of the liquid flow channel are formed between the first portion of the wall of the tube, the disc shaped protrusion, the helicoidal protrusions and the peripheral wall of the intermediate part.
