A baby bottle assembly for bottom venting includes a bottle having a top closure member adapted for releasable engagement with a top portion of the bottle, and a bottom closure member adapted for releasable engagement with a base portion of the bottle. The bottom closure member has a base panel with a raised portion having an air passage therethrough and a top sealing surface. A diaphragm is positionable between the bottom closure member and the base portion. The diaphragm has a disc, at least one moveable sealing element for sealingly engaging the top sealing surface, and an air passage extending under the at least one moveable sealing element into the liquid chamber. The diaphragm is moveable between a sealed position and an unsealed position. The moveable sealing element when in the sealed position prevents liquid contained within a liquid chamber of the bottle from entering the air passage. When in the unsealed position, the diaphragm allows bottom venting of the bottle.

The present invention relates to a baby feeding bottle. The baby feeding bottle employs a simple structure in which an assembly portion having a ring-shaped assembly groove is formed on the outside of the top of a feeding bottle body, a horizontal stop protrusion portion and a vertical coupling protrusion portion are formed on the outside of the bottom of the feeding bottle body, a silicone tube is fined into the outside of the feeding bottle body, a ring coupling portion at the upper end of the silicone tube assembly groove is coupled to the assembly portion in a sealed manner by being inserted to the assembly portion, and a horizontally bent portion at the lower end of the silicone tube is coupled to the stop protrusion portion in a sealed manner by locating the horizontally bent portion and then pressing the horizontally bent portion with the sealing cap.

A feeding bottle has a first layer and optionally a second layer. The feeding bottle offers an improved user experience by mitigating against spills, leaks, improving feeding comfort, or offering information to the user about the feeding environment. The feeding bottle has a reusable liner that is compatible with breast pumps. The liner stores fluid such as breast milk in the freezer. The liner is adaptable to feeding bottle holders, collars, and/or nipples and thus facilitates feeding infants. The liner is adaptable to breast pumps, a liner cap, and one or more of a bottle holder, collar and nipple, such that the liner offers a pump, store, feed solution that is reusable and simplifies the number of parts required for any/all of pumping, storing and feeding activities.

There is disclosed a drinking receptacle comprising: a container for containing a fluid for drinking; and an outlet member having an outlet through which the fluid is delivered under a pressure supplied by a user of the receptacle and a collar portion that attaches to an opening of the container such that an undersurface of the collar portion abuts with an upper surface of the opening of the container to form a substantially sealed engagement between the outlet member and the container; wherein either the undersurface of the collar portion or the upper surface of the opening of the container has at least one vent formed therein, the at least one vent being configured such that when said pressure is applied to the outlet member the at least one vent member permits the controlled ingress of air into the container to facilitate flow of fluid from the outlet, and when said pressure is removed the at least one vent member substantially prevents the ingress of air into the container to facilitate a controlled vacuum pressure within the container.

A pacifier structure is mounted on a nursing bottle containing a rotatable cap, a body, and a filtration member. The rotatable cap includes a peripheral groove, the body includes a suction portion and a surround plane, the surround plane has an air valve, the surround plane connects with the peripheral groove to produce an air chamber, and a trench is defined between the body and the peripheral groove. The filtration member includes a ring portion, at least one connection tab, and a mesh portion. The ring portion has an arcuate recess, a diameter defined by the at least two connection tabs is more than an inner diameter of the body, the mesh portion has a large section adjacent to the ring portion and a small section away from the ring portion. The large section has a greater diameter than the small section, and the mesh portion has multiple orifices.
