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.
1 Claim, 7 Drawing Figures NURSING BOTTLE BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to baby nursing bottles of the type which include a disposable collapsible insert for holding the milk.
2. Summary of the Invention A nursing bottle including a corrugated air admitting ring engaged with the top of the bottle supporting a sealing ring on the top of a collapsible insert. The nipple engages the sealing ring and a perforate screw cap binds the nipple in sealing engagement with the sealing ring of the collapsible insert. Air is permitted to flow into the bottom through the perforations in the cap and between the corrugated ring and the bottle top as required to balance the pressure within the bottle with the ambient pressures.
In a modified form of the invention the collapsible insert is engaged over the threads of a perforate bottle and a cap sealingly engaging a nipple engages over the insert and threads to secure and seal the insert in the bottle.
The primary object of the invention is to provide a nursing bottle which includes a disposable collapsible bag which will prevent air from reaching the infant.
Other objects and advantages will become apparent in the following specification when considered in the light of the attached drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures the reference numeral 10 indicates generally a nursing bottle constructed in accordance with the invention.
The nursing bottle 10 includes a generally cylindrical container 11 having a neck 12 threaded at 13 on its upper end. The container 11 may be formed of any suitable material such as glass, plastic or rubber. A corrugated ring 14 is provided with a pair of oppositely disposed depending ribs 15, 16 which are adapted to engage in the bottle 11 to support the ring 14 in position on the top of the threaded neck 12. The ring 14 is perfectly flat on its upper surface 17 and has its lower surface 18 corrugated to maintain an air space between the top of the bottle neck 12 and the ring 14. A plastic insert 19 is positioned in the bottle 1 1 and has an annular sealing ring 20 integrally secured to its upper end for supported engagement with the ring 14. A screw cap 21 is adapted to threadably engage the threads 13 to thus clamp a nipple 22 against the upper face of the ring 20 on the collapsible insert 19. The cap 21 has a bore 23 to permit the nipple 22 to extend upwardly therefrom. The cap 21 also has a plurality of bores 24 formed therein around the periphery thereof. The bores 24 allow air to enter the cap 21 and to enter the bottle 11 through the corrugations 18 in the ring 14. In the use and operation of the invention the bottle 11 is assembled with the corrugated ring 14 engaging the upper edge of the neck 12 and with the ring 20 of the insert container in sealing engagement with the upper face of the corrugated ring 14.
The plastic ring supports 15, 16 are of course within the container 11. The cap 21 is screwed under the threaded neck 12 of the container 11 to provide a seal between the nipple and the collapsible container. As the infant uses suction to empty the baby nursing bottle container air is admitted to the container 11 through the corrugations l8 and the bores 24 to fill the space in the container 11 created when milk was removed from the bag 19 by suction.
Referring now to FIGS. 5 through 7 a modified nursing bottle is indicated generally at 110. The nursing bottle includes a generally cylindrical container 111 having a neck 112 threaded at its upper end at 113. The container 111 has a bore 114 formed in the bottom thereof to balance the air pressure inside and outside of the container 111. A flexible collapsible plastic bag 115 is positioned in the container 111 and has the upper portion 116 thereof reversed and engaged over the threads 113 on the neck 112. A screw cap 117 has a central bore 118 to receive a nipple 119. The cap 117 is adapted to mate with the threads 113 with the reverted portion 116 of the bag 115 therebetween. A sealing ring engages between the nipple 119 and the upper edge of the bag 115 to seal the nipple to the bag to prevent the loss of milk or the admission of air therebetween.
In the use and operation of the invention as the infant removes milk from the bag 1 15 by suction on the nipple 119 air flows into the container 111 through the bore 114 to balance the pressures in the container 111 with respect to the atmosphere so that no air of any kind reaches the infant through the nipple 119.
The container 111 like the container 11 may be formed of any desired material such as glass, rubber, plastic and the like.
Having thus described the preferred embodiments of the invention it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the spirit of the invention.
1. A nursing bottle comprising a container, an externally screw threaded neck on said container, a ring corrugated on its lower surface for engagement with the open end of said neck, said ring having a planar upper surface, a pair of ribs integrally secured to the opposite sides of said ring for engaging within said container to maintain said ring in contact with the open end of said neck, a flexible collapsible bag removably positioned in said bag, said ring and the neck of said container together, said perforations in said ring cap and the corrugations in said ring providing an airway to admit air to the space between said bag and said container as fluids are removed from said bag.
