The invention relates to a device for equalizing the pressure inside a milk-containing baby bottle, by bottom venting, during suction from the nipple.

The device is positioned inside the cover which closes the bottom of the baby bottle.

The cover comprises a dome-shaped element axially emerging from said bottom wall, which has at least one hole located in its cusp-shaped end and in communication with the environment outside the cover.

A diaphragm member with a flexible region is placed above said dome-shaped element of the cover and, when the device is mounted in the bottle, is arranged axially above said hole.

A central disk-shaped element is provided in the flexible region and has at least one cut that opens toward the hole and hence toward the exterior of the bottle, as milk is being sucked, and equalizes the pressure inside the bottle.

The flexibility of the flexible region is obtained, in particular, by the presence of a central dome-shaped region, an annular depression, concentric with said dome-shaped region, located radially outside the latter, and an annular rib, concentric with said depression, located radially outside both said depression and said dome-shaped region.

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.

Provided is a nursing bottle. The nursing bottle includes a bottle body and a bottle bottom. The bottle body is detachably connected to the bottle bottom. Both the bottle body and the bottle bottom are made of silica gel, and the bottle body has an arc shape imitating a woman's breast. An outer side of the bottle body is provided with a nipple. The nipple is provided with a water outlet. The bottle body is provided with a containing cavity and a first opening. A storage bin for storing liquid is provided in the containing cavity. The water outlet is in communication with the storage bin. A side of the storage bin facing towards the bottle bottom is provided with a second opening. Reinforcing ribs are provided between the cavity wall of the containing cavity and the outer periphery of the storage bin.

A self-warming bottle assembly includes a bottle that may contain a fluid. The bottle has a chamber that is fluidly discrete from an interior of the bottle. A warming media is positioned within the chamber. Thus, the warming media selectively warms the fluid in the bottle. A sleeve is removably positioned around the bottle and the sleeve may be manipulated. The sleeve inhibits the warming media from warming the fluid.
