The device (1 ) comprises a cannula (10), constituted by an upper portion (10A) and a lower portion (10B), divided by a plate (11 ); a teat (20) is associated to the upper portion (10A), which at a base thereof forms an annular appendage (21 ) for covering the plate (11 ) and, externally of the appendage (21 ), a bonnet (22). The lower portion (10B) is externally provided with a helical tongue (31 ) and at a lower end (14) thereof is equipped with means for perforating (40), and inserts in a hole (102, 202) made in a wall (101, 201 ) of a container (100, 200). For tetrapak brick containers (100), means for perforating (40) are used to realise the hole (102), a rim of which is screw-engaged with the helical tongue (31 ); in this case the bonnet (22) rests on the wall (101 ) and protects the hole (102). For containers (200) constituted by plastic bottles, the lower portion (10B) is inserted in the hole (202), the bonnet (22) is bent to adhere to a neck (201 ) of the bottle (200) and is connected-up to anchor the device (1 ) to the bottle (200). |
