<p>The invention provides a baby feed bottle and combination thereof with a screw fitting annular cap to which a teat, preferably moulded of liquid silicone rubber may be assembled before the cap is fitted to the bottle. The bottle is dimensioned with a large capacity per cm height, giving it an unusually large diameter, and the externally threaded neck (12) in particularly wide mouthed as it also has a large diameter of the order of three-quarters the diameter of the main portion (10) of the bottle. The teat is moulded with shape and dimensions such that, when the annular cap/teat subassembly is fitted to the bottle and screwed down, a flap valve arrangement is produced by a depending lip (35) on the teat which seals against the interior of the bottle neck. The flap valve arrangement is operative when the bottle is used to prevent collapse of the teat mouthpiece. (FIGS. 1, 4 and 6).</p> |
