A teat including at least a shaft and a nipple, wherein structured surface areas are provided at least in a partial region thereof, and the structured surface areas are formed by at least one rough surface zone having a surface roughness of 100 m at the most, or 50 m at the most.

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.

Embodiments described herein include a baby bottle with integrated pacifier apparatus and method of use including a substantially elongated baby bottle and nipple mounted assembly which includes a pressure valve mechanism configured to regulate the flow of liquid through the nipple and prevent excess air from being ingested.

A drink container with torque-limiting lid is provided. The drink container includes a lid that can be threadably coupled to a container body having a volume to hold fluids. The lid can include an inner lid assembly concentric with an outer lid assembly. The inner lid assembly can include a multiple ratchet teeth along an outer perimeter and the outer lid assembly can include one or more ratchet pawls along an inner perimeter and configured to engage the ratchet teeth. Rotational force on the outer lid assembly can be transferred to the inner lid assembly from the ratchet pawls to the ratchet teeth to threadably couple the inner lid assembly to the container body. Once a torque limit is reached, the ratchet pawls can slip along the ratchet teeth preventing further tightening of the inner lid assembly to the container body.

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 one connection tab 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 is more than the small section, and the mesh portion has multiple orifices.

A child feeding system includes a spout pouch having a spout and a pouch formed integrally with the spout and configured to hold a liquid for feeding to a child, and a holder having a top and a body, the top having an opening configured to laterally receive and removably secure the spout to the holder when the spout is pushed transversely into the opening, the opening partially surrounding the spout, and the body having an interior area configured to receive at least a portion of the pouch. Other systems, methods, and components are also provided.

Closures are provided consisting of a lid or cap member and a container member. These are inter-engageable with one another. The lid or cap member has a skirt and the container member has an upstanding rim, each of which is of generally polygonal (preferably square) shape. Located on each of the facing walls on each side of the polygonal shape are inter-engageable projections. The inter-engaging surfaces of the projections run substantially in a plane perpendicular to the axis of the polygonal shape and are of relatively small angular extent about that axis. The material of one or both of the skirt and container portion is resiliently elastic. The closure may be assembled with an axial push, and removed by twisting.

It is important for the healthy growth of infants or newborn animals that any artificial teats or nipples that are used to feed them, are designed to provide consistent and measured flow rates when in use. Slits in the end of artificial teats or nipples are often used to provide openings for milk flow, and the slits naturally close to seal the end of the teats or nipples when not in use. However, slits need to be carefully aligned with the suckling action of the infant or newborn animal for the milk to flow at a correct rate. An artificial teat with a number of slits, each orientated at a different angle, and which are situated within a generally circular shaped valley or ridge that is formed in the end of the artificial teat or nipple is also disclosed.

A spring loaded nipple assembly includes a cover including a top wall and a perimeter wall that is attached to and extends downwardly from the top wall. The perimeter wall has a cylindrical shape and the top wall has a central opening extending therethrough. A nipple is integrally coupled to the top wall and extends upwardly therefrom. The nipple extends around the opening and forms a seal around the opening. The nipple has a distal end with respect to the top wall and the distal end has an aperture extending therethrough. A threading engagement member is positioned on an inner surface of the perimeter wall. The threading engagement member engages threading on a neck of a fluid container.

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.
