The invention relates to a feeding bottle device, feeding method and a partitioning component (210) for a feeding bottle device (100), comprising a teat component (110) defining a teat volume (115) therein and a container component (120) defining a container volume (125therein, 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 air and liquid between the container volume (125) and the teat volume (115) and a second passage (214) comprising at least one through hole such that the surface tension of an air bubble will not allow the passage into or out of the teat volume (115) up to a predefined pressure difference.

According to a first embodiment, a feeding bottle comprises a vessel, collar, and nipple. The nipple comprises a base portion, a teat portion, an areola portion allowing movement of the teat portion towards and away from the base portion. According to a second embodiment, a feeding bottle comprises a vessel, collar, nipple and handle portion removeably secured to the vessel by the collar. The invention includes a flexible region or regions to provide a more natural feeding by closely mimicking the human breast.

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 container comprises a nipple, a cap, a ball, a slide connecting a short tube and a long tube. The ball travels inside the slide. The short tube has a short tube bottom and is used for the lying position. The long tube has a long tube bottom and is used for the sitting position. The slide has a slide bottom. The slide bottom and the short tube bottom are interchangeable. When the ball seals the upper portion of the long tube, opening the short tube for fluid flow at the lying position. When the ball seals the short tube bottom, the short tube is closed opening the long tube for the fluid flow through the long tube at the sitting position. The nipple draws in the fluid from either the short or long tube depending upon the position a user is taking.

The present invention overcomes the disadvantages of the prior art and provides for an improved method and apparatus for self-sterilizing a bottle. A self-sterilizing bottle comprises a container, a mouthpiece, a collar and a cap. The container has a sidewall and a bottom defining a liquid holding space, with the sidewall forming an open end with a neck. The collar has a first position and a second position and is adapted to fasten to the neck and for removably fastening the mouthpiece to the collar when in the first position. The cap is configured to have an upright position and an inverted position and when in the upright position is adapted to fasten to the collar and cover the mouthpiece when the mouthpiece and cap are attached to the collar and when in the inverted position to rest stably on a surface. Also when in the inverted position, the cap is further adapted to hold a liquid and support the collar above the liquid when the collar is in the second position.

In another embodiment, a method for self-sterilizing a bottle is described wherein the bottle comprises a cap, a collar, a mouthpiece and a container having an open end. The method comprises placing the cap on a support surface in a position to hold a liquid. Then adding a liquid to the cap. Then placing the collar on the cap so that the collar remains above the liquid in the cap. Then placing the mouthpiece within the container. Then placing the open end of the container with the mouthpiece therein on the collar to form a self-sterilizing assembly. Then placing the self-sterilizing assembly in a microwave oven. Then heating the self-sterilizing assembly in a microwave oven for a time sufficient to sterilize the self-sterilizing assembly.
