A teat for a milk bottle is provided. The teat comprises an attachment portion for attaching the teat to a milk bottle. A breast portion of the teat extends from the attachment portion, the breast portion including a compressible material. A nipple portion of the teat extends from the breast portion. The nipple portion is narrower than the breast portion and includes an outlet. A milk-flow pathway extends through the breast portion, the compressible material and the nipple portion for the passage of milk from a milk bottle attached to the attachment portion to the outlet. The breast portion includes a flexible skin fully enclosing the compressible material, the flexible skin separating the compressible material from the milk-flow pathway.

A vessel includes an inner container, an outer container, a connector, a cap, and a lid. The outer container includes a first coupler and an outer chamber. The inner container includes a second coupler and an inner chamber to hold a liquid. The inner container is receivable at least partially within the outer chamber. The connector includes a third coupler that is complementary to the first coupler, and a fourth coupler that is complementary to the second coupler. When both the first coupler is engaged with the third coupler and the second coupler is engaged with the fourth coupler, the outer chamber is entirely enclosed within a liquid-proof barrier.

A container including at least one connection opening and at least one connection part, wherein grooves and engaging elements are provided as interacting connection elements to connect the container and the connection part, and in the connected state a respective engaging element is arranged in a receiving portion of a groove, which receiving portion is arranged substantially perpendicular to a longitudinal axis of the container, wherein the container and the connection part have run-on elements with run-on surfaces which run obliquely with respect to the longitudinal axis of the container, which run-on surfaces interact by means of rotational movement between the container and the connection part, in such a way that the engaging elements can be moved out of the receiving portion of the respective groove and, in a rotated position, the engaging connection between the container and the connection part is released.

A nut for ensuring compatibility of a nipple having an anti-colic valve affixed to a baby bottle having a bottom vent and a mouth; the nut comprises a flange which has a central opening for receiving the nipple extending therethrough, the central opening has an edge configured to engage in an annular groove of the nipple, the nipple also comprises a flange; the nut comprises means for inhibiting the anti-colic valve which comprise: a first annular rib formed on the inner surface of the flange, which is configured to abut the flange of the nipple between the anti-colic valve and the edge of the central opening of the flange, a second rib, concentric with the first rib, which is configured to provide a hydraulic seal between the flange of the nipple and the mouth of the baby bottle, a depression interposed between the first rib and the second rib, which is configured to abut against the anti-colic valve of the nipple when the nut and the nipple are coupled together and are applied to a baby bottle to inhibit the anti-colic valve.

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.
