A teat feeding bottle comprises a container (1) having a neck portion (11) which includes external threads (12) and a pierceable wall (13). A screw cap (5) is provided with internal threads (53) and a flange (52) which sealingly clamps a flange (42) of the teat. A spike (3) accommodated completely within said teat and having a pointed tip (31) on its one end and a pushbutton-like enlargement (32) on its other end, is guided within an opening (22) of a longitudinal guiding portion (2). The longitudinal guiding portion (2) extends partially into the interior of the teat (4) and has a flange (21) thereof fixed by the screw cap (5). The spike (3) has a longitudinally (axially) extending groove (33) which, in combination with the wall of opening (22) opposing this groove, defines a passage for liquid dispensed from the container (1) when the spike has penetrated the pierceable wall (13). Upon penetration of this wall, the spike remains within the interior of the teat or of the container (1), respectively.
In a teat feeding bottle comprising a container, a screw cap, a teat and a spike, said teat having a peripherally extending flange sealingly clamped by the flange of said screw cap against a neck portion of said container, said teat freely extending outwardly from said screw cap, said spike extending to the top of said teat and positioned substantially vertically and the pointed tip of said spike being spaced from a pierceable wall of said container, the improvement characterized by a longitudinal guiding portion for the pointed tip of said spike, said guiding portion being clamped between said pierceable wall and said flange of said screw cap;
