The interior of the nipple assembly 104 may additionally include an internal flow assist mechanism for assisting the fluid flow while the nipple head is bitten or pulled.

The present invention relates to a feeding bottle device (100) comprising at least one air vent valve (140) for allowing the passage of air from outside the feeding bottle device (100) to within a container volume (125) when the feeding bottle device (100) is assembled, a confined volume forming component (150) for defining a confined volume (155) within a container volume (125) of a container component (120) of the feeding bottle device (100), wherein the confined volume (155) is configured to provide a controlled opening (165) for air entering through the air vent valve (140) into the container volume (125), and an optional duct forming component (170) for forming a guidance duct (175) from the at least one air vent valve (140) to the confined volume (155). The feeding bottle device (100) reduces the risk of colic-like symptoms for an infant.

A nursing bottle having an air returning function comprises a bottle body, a fixing cover, a nipple, a ventilation component, an air conduit, an elastic one-way valve set at a second opening of the air conduit and is located at the interior of the air conduit, a mounting part located on the second opening of the air conduit to secure the elastic one-way valve. The ventilation component, the air conduit, the elastic one-way valve and the mounting part form a gas returning device and are located on the interior of the bottle. The bottle reduces the contacting area between the air and the milk, lowering the amount of vitamin loss. The phenomenon of vomiting milk, choking and flatulence will be omitted since no air bubble is generated.

The present invention relates to a partitioning component (210) for a feeding bottle device (100), the feeding bottle device (100) comprising a teat component (110) defining a teat volume (115) therein and a container component (120) defining a container volume (125) therein, the teat component (110) being attachable to the container component (120) by means of an attachment component (130). The partitioning component (210) comprises a first passage (212) allowing a passage of fluid from the container volume (125) to the teat volume (115) and a second passage (214) allowing a passage of fluid from the teat volume (115) to the container volume (125), wherein the second passage (214) is provided in the form of a one-way passage. The invention further relates to a corresponding feeding bottle device (100) and a feeding method. The solutions according to the invention reduce the risk of colic-like symptoms for the infant.

An internal element (310) for a feeding bottle (100) is provided, the feeding bottle comprising a teat component (110), and a container component (120), which together define a bottle volume extending longitudinally between a base end of the container component, and a top end of the teat component. The internal element (310) comprises a disc element (620) configured to be positioned within the bottle volume extending transverse the longitudinal axis, and further comprises one or more tab elements (640) protruding from an outer periphery (630) of the disc element for being received between interfacing parts of a coupling arrangement (340, 342) of the bottle.

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.
