Abstract
Abstract A nursing bottle supporting a collapsible container and with its cap securing a nipple thereto. An air inlet ring is mounted on a pair of members which extend into the bottle outside the insert to hold the ring in position as the bottle is being assembled. The air inlet ring is corrugated on the bottom side to prevent its sealing with the bottle to permit air to flow into the space between the bottle and the insert. In a modified form of the invention the insert is folded over the threaded top of the bottle and the cap, holding the nipple, is threaded over the insert to seal the insert to the top of the bottle and the nipple. The bottle is perforate to admit air as the collapsible insert collapses.
