A container for collecting, transporting, storing, delivering and dispensing fluid. The container has a hollow tube with an outer circumference diameter and is configured to receive a plunger. A collection adaptor and a dispensing adaptor provide interchangeable coupling of a variable volume container such as a syringe with a collection device such as a breast pump and a dispensing device such as a nipple. The container also has a circumferential seal assembly secured at one end of the hollow tube. The seal assembly outer diameter is substantially similar to the hollow tube outer diameter.

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.

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.

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.

Disclosed is a disposable container that includes a body portion, a sealing collar, a nozzle, and a sealing disc. The body portion is having a threaded neck formed from the body portion. In an aspect, the body portion is made of a laminated material. The sealing collar adapted to detachably attached with the body portion. The nozzle is removably fixed to the body portion with the sealing collar adapted to be screwed on to the threaded neck. The sealing disc disposed between the sealing collar and the nozzle to stop the flow of a beverage to the nozzle.
