A feeding bottle teat includes a body having an interior cavity and an exterior surface, an inlet including a flange for engagement within an aperture of a feeding bottle cap in use, and a nipple including one or more outlet apertures wherein the flange, cavity, nipple and apertures form a passageway for delivery of milk from the bottle in use, wherein a transverse dimension of the interior surface of the body at the inlet is greater than a transverse dimension at the nipple, and wherein the interior surface includes a plurality of concentric strengthening formations extending inwardly from the inner surface between the inlet and the nipple, wherein the strengthening formations comprise coaxial concentric spirals which rotate about a common central axis, wherein each strengthening member comprises a spiral having two to four rotations about the central axis.

A breastfeeding device is disclosed comprising a liquid pouch assembly, a silicone housing, a silicone areola, and an adjustable strap. The liquid pouch assembly comprises a nipple removably coupled to an amorphous liquid bag. The silicone housing comprises a silicone cup and a rear silicone component attached to one another and forming an interior cavity. An entrance to the cavity is formed at the top of the silicone cup and the rear silicone component, and the liquid pouch assembly is insertable through the entrance. The silicone cup includes a central hole. The nipple of the liquid pouch assembly is insertable into the central hole and protrudes through the central hole while the amorphous liquid bag remains within the interior cavity. The silicone areola is external to the silicone housing, and the silicone areola is removably coupled to the nipple and concentric with the central hole of the silicone cup.

A bottle teat (1) having a base portion (2), which has a connecting flange (3) and in which the bottle teat (1) is substantially circular in a cross section running perpendicularly to a longitudinal axis (9), having a lip-support portion (5) and having a nipple portion (6), which opens out in a teat tip (7), wherein, in a direction perpendicular to its longitudinal axis (9), the bottle teat (1) has, in the lip-support portion (5), a non-circular cross section with a longitudinal axis (10) and a transverse axis (11), which is shorter than the longitudinal axis (10), characterized in that the base portion (2) and the lip-support portion (5) have provided between them a flex portion (4), which has enhanced flexibility in relation to the base portion (2) and the lip-support portion (5), wherein the flex portion (4) has a circumferentially encircling depression (15) in the form of anindent (19) and/or of a smaller wall thickness than in the portions adjacent to the depression (15), and therefore, about an axis running substantially in the direction of the transverse axis (11), the bottle teat (1) has a level of flexibility, for the purpose of pivoting the lip-support portion (5) and nipple portion (6), which is enhanced in relation to a similarly designed bottle teat without a depression.

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.

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.

An apparatus for use with baby bottles, a baby bottle assembly, and a method of preparing liquid infant formula for feeding to a baby are disclosed. A measuring and mixing pod allows the appropriate amount of powdered infant formula to be measured out in advance and stored within the baby bottle from which it is to be served. The same bottle may be filled with water or other liquid while keeping the powdered formula dry. Further, a simple and quick method is provided for mixing the powdered formula with the liquid stored in the bottle when it is time to feed the baby.

The production of a protein free synthetic polyisoprene which has both low levels of chemical impurities and good physical properties has yet to be realized. It has now been envisioned that the use of neodymium catalyzed polyisoprene will offer the combined advantages of both a clean, as well as, high cis-1,4 polymer. Synthesis of polyisoprene rubber using a neodymium based catalyst system is described. Characterization of the material shows the absence of an ultra high molecular weight fraction and the presence of very high cis-1,4-microstructure. Gum stock and black filled compound studies comparing neodymium polyisoprene with natural rubber, titanium polyisoprene, and lithium polyisoprene have been performed. Results indicate that polyisoprene rubber synthesized using a neodymium catalyst system (NdPI) has similar stress-strain and tear properties as synthetic titanium polyisoprene. Analysis of residual volatile, extractable, and oligomer levels indicates NdPI is indeed a clean source of high cis synthetic polyisoprene.

Apparatus and methods provide for a feeding bottle. According to embodiments described herein, a feeding bottle may include a container and a one-piece nipple assembly. The one-piece nipple assembly may include a ring substrate encompassed by a dome overmold with a nipple head. The nipple head and dome overmold may include a texture gradient and variable wall thickness to simulate a human breast. The interior of the nipple assembly 104 may additionally include an internal flow assist mechanism for assisting the fluid flow while the nipple head is bitten or pulled.
