The disclosure discloses an anti-flatulence milk bottle, which comprises a bottle body and a nipple, wherein an edge of the nipple is arranged at a bottleneck of the bottle body through a threaded cover, the threaded cover is in threaded connection with a periphery of the bottleneck, a first air returning cover and a second air returning cover are arranged between the nipple and the bottleneck, a first gap is formed between the first air returning cover and the second air returning cover, a second gap is formed between the threaded cover and an outer surface of the bottleneck, the first gap is communicated with the second gap, the first air returning cover is provided with a first opening communicated with an interior of the bottle body, and the first gap, the second gap and the first opening form a confluence passage.

A bottle assembly includes a container having a liquid chamber defined therein, and a vent assembly positionable substantially entirely within the liquid chamber of the container. A collar assembly generally defines a closure for the container and is releasably engageable with a neck of the container. The collar assembly and the container are configured relative to each other to enable selective configuration between a first configuration in which the vent assembly is disposed substantially entirely within the liquid chamber of the container and a second configuration in which the vent assembly is omitted from the container.

Bottle apparatuses, storage containers used in bottle apparatuses, beverage dispensing apparatuses, and methods of making and using the same are disclosed. A bottle apparatus can include a neck portion; a bottle portion having an upper end and a lower end, the bottle portion defining an internal volume, and the neck portion attached to the upper end of the bottle portion; a base portion attached to the lower end of the bottle portion; a dispense assembly attached to the neck portion, and the dispense assembly providing for outflow of consumable liquid from the bottle portion; and a flow meter assembly disposed within the base portion, and the flow meter assembly monitoring an amount of the consumable liquid that flows out of the dispense assembly.

There is disclosed a drinking receptacle comprising: a container for containing a fluid for drinking; and an outlet member having an outlet through which the fluid is delivered under a pressure supplied by a user of the receptacle and a collar portion that attaches to an opening of the container such that an undersurface of the collar portion abuts with an upper surface of the opening of the container to form a substantially sealed engagement between the outlet member and the container; wherein either the undersurface of the collar portion or the upper surface of the opening of the container has at least one vent formed therein, the at least one vent being configured such that when said pressure is applied to the outlet member the at least one vent member permits the controlled ingress of air into the container to facilitate flow of fluid from the outlet, and when said pressure is removed the at least one vent member substantially prevents the ingress of air into the container to facilitate a controlled vacuum pressure within the container.

A feeding assembly generally comprises a container having an open top and defining a liquid chamber therein for holding a liquid. A collar assembly defines a closure for the open top of the container upon assembly with the container. The collar assembly includes a collar releasably securable to the container and a nipple coupled to the collar and having an opening through which liquid exits the feeding assembly during feeding. A vent assembly is positionable at least in part on the open top of the container and is configured to facilitate venting of the container to atmosphere as liquid exits the feeding assembly during feeding. The vent assembly is disposed intermediate the container and the nipple and has a vent tube through which air is able to flow from external of the feeding assembly to the container during feeding. The vent tube has an internal rib extending longitudinally of the feeding assembly and is configured to facilitate the flow of liquid from vent assembly back into the container when feeding is ceased and the container is oriented generally upright.

An insert that has a one-way valve that allows for one-way flow of liquid in response to reduced pressure. The insert is configured to be installed in a baby bottle to form two chambersa reservoir chamber and a dispensing chamber. The insert also is provided with a valve failure mechanism which allows a user to force the one-way valve open in the absence of reduced pressure, which allows a user to prime the dispensing chamber (the nipple) prior to beginning feeding.
