A bottle assembly is provided including a bottle having an end portion with 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 including a base member and a sealing member. The sealing member is movable, 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 are arranged to allow air to enter the drinking vessel when the sealing member is in the unsealed position.

The present application relates to the technical field of baby appliance structure, and provides a feeding bottle, including: a body and at least one non-return valve integrally formed at a lower of the body. The non-return valve includes a connection portion that is connected at the body, an extension portion for disturbing the laminar flow state of the internal liquid of the body when shaking the body, and a valve for allowing only the air outside to enter into the body, the extension portion is tapered and extends along a surface of the body toward the interior of the body, the extension portion is located at the inside of the bottom of the body, or located above the inside of the bottom of the body and in the vicinity of the inside of the bottom of the body. This design can solve the problem that the structure of the existing feeding bottle may cause flatulence to the baby due to the unbalanced pressure and may easily lead to incomplete dissolution of the milk powder.

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.
