A bottle assembly includes a container, a collar assembly, and a vent insert. The collar assembly includes a collar and a nipple. The vent insert is configured for selective placement on an open top of the container. The vent insert, when placed on the open top of the container, defines a gap for allowing liquid in the liquid chamber of the container to flow towards the nipple and a vent passage having at least one vent opening in flow communication with the liquid chamber for allowing air to flow into the liquid chamber. The vent insert further defines an annular gap forming a portion of the vent passage. The bottle assembly is selectively operable in two different configurations, a first configuration in which the vent insert is placed on the open top of the container and a second configuration in which the vent insert is omitted.

A bottle assembly includes a container having an open end, a closed end, a base portion, and a neck together defining a liquid chamber within the container. The neck has a rim defining the open end of the container. The bottle assembly also includes a collar assembly generally defining a closure for the container. The collar assembly is configured for releasable engagement with the neck of the container over the open end thereof. The collar assembly includes a collar and a nipple. The bottle assembly further includes a cap including a closed end, an open end, and a side wall extending between the closed end and the open end together defining an interior. The cap is configured for releasable engagement with the collar assembly such that the nipple is received within the interior of the cap. In some embodiments, the bottle assembly includes a vent assembly positionable at least in part on the rim of the container to permit venting of the container during use.

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 universal single piece venting insert for a container, the insert, when applied, holding a vent tube in position within the container, and extending in proximity with its interior bottom, the vent insert forming a cylindrical member, having an integral flange, the cylindrical member extends through the lid of the container, and the flange is otherwise adhered or held contiguously against the exterior of the lid, to function as a support for the venting structure. The interior of the venting insert, and more specifically its cylindrical member, has a series of communicating channels, a first tapered channel extending upwardly from its bottom, a second flaring portion extending further upwardly within the member, and the remainder being a cylinder forming the vent reservoir, where liquid may accumulate when the container is inverted during consumption of its fluids.

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.
