<p>An assembly for mounting a nipple (18) to a baby bottle (10) includes an adapter (24) supporting the nipple against free movement through the bottle mouth, and a mounting collar (32) with thread portions (46) engaging complementary thread portion (44) on the bottle and clamping the nipple (18) and adapter (24) to the bottle. The position of the thread portions allows free rotation of the collar (32) relative to the bottle in the absence of the adapter (24) so as to draw attention to incorrect assembly. <IMAGE></p> |
