A partitioning component for a feeding bottle device. The feeding bottle device comprising a teat component defining a teat volume therein and a container component defining a container volume therein. The teat component being attachable to the container component by means of an attachment component. The partitioning component comprises a first passage allowing a passage of fluid from the container volume to the teat volume and a second passage allowing a passage of fluid from the teat volume to the container volume, wherein the second passage is provided in the form of a one-way passage. The invention further relates to a corresponding feeding bottle device and a feeding method. The solutions according to the invention reduce the risk of colic-like symptoms for the infant.

A nipple for use with an infant drinking cup is disclosed herein. The nipple comprises a domed portion having a central region and an inner surface, a teat portion radially offset from the central region, and a radially-outer wall. The radially-outer wall is joined to the domed portion at a joining location and comprises an inner fluid-flow surface, defining a fluid flow direction. A region of the inner surface of the domed portion at the joining location is substantially parallel to said fluid flow direction, or the inner fluid-flow surface of the teat portion extends radially outwardly, away from said region of the inner surface of the domed portion at the joining location.

Embodiments of the systems and methods described herein include a system of improved silicone bottle containers, adapters, and nipples that support the collection, storage, and feeding of breast milk. In some embodiments, a bottle system may include a bottle formed from molded silicone rubber including a bottom end having a recess, and a top end having an opening configured to receive and dispel contents, wherein the top end is spaced apart from the bottom end, and an inner adapter composed of molded standard thermo-plastic configured to engage with the top end of the bottle. The bottle system may also include a flat cap, nipple, nipple cover, nipple adapter, and/or breast pump adapter.

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.
