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.

A baby bottle device (100) is provided which comprises a teat (110) having a teat volume (115), a container (120) having a container volume (125) and a partitioning element (300) between the teat volume (110) and the container volume (125). The partitioning element (300) comprises a plurality of openings (310) for letting fluid in the container volume (125) flow into the teat volume (115). The baby bottle device comprises a floater (400) having a buoyancy, being coupled to the partitioning element (300) and being adapted to close at least one of the plurality of openings (310) in the partitioning element (300).

A vent valve, and a vent valve assembly, for a liquid dispensing container, employ a vent disc having small open vent holes in cooperation with an overlying thin flexible flap that covers and closes the vent holes to limit liquid pressure on the holes when the container is upright, yet require little suction pressure to move the flap to draw liquid or vent through the holes. The vent valve can be used in a bottom cap that is attachable to the bottom open end of the container. The vent valve assembly includes such a bottom cap, a sealing member for sealing the bottom cap to the container, and a vent valve. The vent valve and/or bottom cap have an elevated vent disc and a top portion having the thin flexible flap.

In one aspect of the invention features nursing bottle. The nursing bottle includes a container for holding a liquid and having a rim defining an open end and a nipple assembly secured to the container at the open end. The nipple assembly includes a flexible nipple extending away from the container and defining an interior nipple volume, a vent bulb disposed within the interior nipple volume and defining an interior bulb volume, a tube extending into the container to a distal end disposed in a closed end of the container, and a vent manifold. The vent manifold defines a first aperture providing fluid communication between the container and the interior nipple volume, a second aperture providing fluid communication between the tube and the interior bulb volume, and a vent conduit providing fluid communication between the interior bulb volume and atmosphere.

A bottle assembly is provided. The bottle assembly comprises a bottle having an end portion including a first detent formation, and a collar having a second complementary detent formation. The collar is arranged to snap fit to the end portion by engagement of the detent formations by application of force only in a direction towards the bottle. In addition, a valve assembly for use with a drinking vessel is provided. The valve assembly comprises a base member and a sealing member. The sealing member is moveable, dependent on a pressure difference across it, between a sealed position, wherein the sealing member is sealed against the base member, and an unsealed position, wherein the sealing member is unsealed from the base member. One or more channels are formed between the base member and the sealing member and extend to a periphery of the sealing member. The one or more channels are arranged to allow air to enter the drinking vessel from the periphery of the sealing member when the sealing member is in the unsealed position.
