A baby bottle is provided for improving feeding tolerance and reducing nipple confusion. The bottle includes a cylindrical bottle; a nipple disk; a valve disk; and a retaining ring. The valve disk prevents liquid flow until the nipple is elongated to at least a predetermined length. The bottle has a threaded surface on an exterior of one end and the retaining ring has mating threads. The nipple disk is configured to mimic a natural breast, with an areola portion and a nipple portion. The valve disk has multiple openings. The valve disk is adjacent to the inside of the nipple disk. The baby bottle includes a piston slides within the bottle. The piston maintains vacuum within the bottle as liquid exits the nipple.

A teat for use with a fluid container comprises a deformable mouthpiece for an infant to suck on during a fluid intake action and an inner core (20) disposed within the mouthpiece. An exterior surface (21) of the inner core (20) is spaced from an interior surface of the mouthpiece at the position of a fluid pocket guiding face (22) of the exterior surface (21) of the inner core (20) so that a fluid duct between the mouthpiece and the inner core (20) is defined which allows the infant to perform a peristaltic fluid intake action. At least one of the interior surface of the mouthpiece and the exterior surface (21) of the inner core (20) has at least one protrusion (23) that is designed to form a fluid barrier between the mouthpiece and the inner core (20) at a position for delimiting the fluid duct at the sides thereof.

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.

Disclosed are artificial nipples and methods of producing artificial nipples. Disclosed are methods of producing an artificial nipple comprising imaging a nipple region of a breast, wherein at least a portion of the breast comprising the nipple region is distorted due to at least a partial vacuum created through motions of lips and a tongue, wherein the imaging provides imaging data of the nipple region; and generating, based on the imaging data, an artificial nipple.

A teat has a stimulation portion for stimulating the incisive papilla. The stimulation portion is located at a central region of the teat between a base region and a tip region.

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 teat (1) for use with a container for containing a fluid comprises a deformable mouthpiece (13) for an infant to suck on, and an inner core (20) disposed within the mouthpiece (13). The mouthpiece (13) has at least one aperture (12) therein for allowing a fluid to flow out of the teat (1). A fluid duct (30) between the mouthpiece (13) and the inner core (20) is defined at the position of a fluid pocket guiding face (23) of the inner core (20) whereby the infant is allowed to perform a peristaltic fluid intake action. The at least one aperture (12) is arranged in a central front area (15) of the mouthpiece (13), while the mouthpiece (13) and the inner core (20) are designed to leave space between them for a fluid flow path from the fluid pocket guiding face (23) to the at least one aperture (12).

The liquid-dispensing pacifier comprises a nipple, a fluid dispenser, and a guard. The guard prevents the liquid-dispensing pacifier from being swallowed by the baby. The nipple is shaped to resemble a female human teat and provides one or more apertures through which a fluid may exit the nipple from a chamber within the nipple. As non-limiting examples, the fluid may be breast milk or formula. The fluid is introduced into the nipple from the fluid dispenser. The fluid dispenser may be a reservoir or syringe that is coupled to the nipple. Fluid may travel from the reservoir to the chamber in the nipple via a valve or feeding tube. The valve may be opened by sucking action of the baby. The syringe may inject fluid into the chamber through one or more apertures, values, or tubes.

The nursing device is for use with livestock. The nursing device is for use with one or more living cats. The nursing device is for use with a liquid feeding formula (hereinafter formula) for use with livestock. The nursing device is specifically for use with a formula for use with a living cat. The nursing device includes a feline shell, a fluid handling system, and an electrical system. The feline shell is a puppet that resembles a cat. The feline shell contains the fluid handling system and the electrical system. The fluid handling system: 1) contains the formula; and, 2) distributes the formula to the one or more living cats. The electrical system: 1) heats the formula; and, 2) creates audible sounds intended to soothe the one or more living cats.

An artificial nipple is formed of an elastomeric polymer by use of 3D printing after imaging of a mother's breast in an active state of lactation. The artificial nipple used as an attachment to a baby bottle or as the nipple component of a pacifier. Use of an artificial nipple formed in this manner mitigates a problem with nipple confusion, as may otherwise manifest in newborn offspring.
