A spillproof container assembly includes a container body and a lid body that is adapted to be fastened onto the container body by screwing. Both the container body and the lid body are advantageously provided with outwardly extending wing portions for enhancing the grippability of and properly orienting the container assembly for small children. The outwardly extending wing portions of the container body are aligned with the outwardly extending wing portions of the lid body. The lid body is provided with an acoustic waveguide, and sound generating structure is provided in communication with the acoustic waveguide for creating an audible feedback when the lid body has been tightened onto the container body to a predetermined relative position and tightness. The acoustic waveguide further functions as a viewing port that provides a visual feedback so that a user can visually verify the position of the lid body with respect to the container body. In addition, the wing portions of the lid body are designed to slightly interfere with and cam over respective upper platforms on the wing portions of the container body so that a user will be provided with a tactical feedback as a lid body is approaching an optimal amount of tightness with respect to the container body.

A baby feeding bottle (1) comprising a cavity (2) adapted to hold a fluid; and a nipple (3) having an opening (4), the nipple (3) is coupled to the cavity, so as to allow the fluid to pass through the opening (4) of the nipple (3), wherein the nipple (3) further comprises a tube (5) which is placed within the nipple (3), and a sealed end (6) of the tube (5) is coupled to the opening of the nipple, and a free end (7) opposite to the sealed end (6) is having a flexible closure (8) adapted to be in an open position to allow the flow of the fluid on application of force onto an outer surface of the nipple (3), and to be in a closed position to disallow the flow of the fluid on removing the force onto the outer surface of the nipple (3). Embodiments including an assembly of the feeding bottle and method for using the feeding bottle is are also presented.

An insert that has a one-way valve that allows for one-way flow of liquid in response to reduced pressure. The insert is configured to be installed in a baby bottle to form two chambersa reservoir chamber and a dispensing chamber. The insert also is provided with a valve failure mechanism which allows a user to force the one-way valve open in the absence of reduced pressure, which allows a user to prime the dispensing chamber (the nipple) prior to beginning feeding.

A feeding assembly includes a container having an open top and defining a liquid chamber therein for holding a liquid. A collar assembly defines a closure for the open top of the container upon assembly with the container. A vent assembly is positionable at least in part on the open top of the container and is configured to facilitate venting of the container to atmosphere as liquid exits the feeding assembly during feeding. The vent assembly being disposed intermediate the container and the nipple, has at least one opening through which liquid is able to flow from the container to the nipple during feeding. The vent assembly has a siphon member extending longitudinally of the feeding assembly and generally away from the nipple and is configured to facilitate the flow of liquid from the nipple back into the container when feeding is ceased and the container is oriented generally upright.
