<p>The bottle consists of the bottle itself (1), which is basically rigid and has an open end (10) and a threaded neck (11). There is a deformable teat (2) with a collar (21) which is fastened to the neck of the bottle by a screw cap (3) comprising a threaded skirt and ring. At least one of the four facing surfaces of the bottle neck, teat collar and ring is positioned obliquely relative to the locking direction produced by the threaded surfaces of the bottle neck and cap, so that the locking effort applied to the collar is different in different sectors. In addition, the surface of the teat collar in contact with the bottle neck has a series of oblique channels to allow air passing through the teat into the bottle.</p> |
