A method of forming a nipple for a baby bottle, comprises: forming a lower conical wall section; forming a higher conical wall section molded above the lower conical wall section; preventing deformation of the higher conical wall section; and cutting an opening through the higher conical wall section into an interior section of the nipple.

A teat for a bottle has a nipple portion at which there is a recessed valve portion. The valve portion is domed outwardly.

A teat (10) for an infant feeding bottle (1), including a resilient wall (12) defining a central nipple (14a) and an areola (14b) that extend around a central axis (L), said teat being elastically transformable between a distended state in which the nipple defines a global maximum (38) and at least one depressed state that is accessible from the distended state by forcing the nipple at least partially into the areola along the central axis, and in which said wall (12) additionally defines an annular double fold (32) that defines an outer local maximum (34) and an inner local minimum (36), both extending circumferentially around the global maximum, wherein the wall defines a circumferential fold region (30) that, in said at least one depressed state, ranges from the local maximum to the local minimum of the double fold, and wherein said fold region has a rotationally asymmetric stiffness distribution.

An improved oral administration coupler for delivery of fluids such as medications and nutritional fluids. Example oral administration couplers have a first end with an applicator for oral delivery to an infant, and a second end with a coupling compatible with an enteral fluid delivery syringe. A fluid delivery conduit extends in fluid communication from the first end to the second end, to deliver fluid from the syringe to the infant. In some example embodiments, the coupler is configured for back-of-mouth delivery, and can comprise a generally elongate and at least partially flexible tube or straw.

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 teat (1, 1′, 1″) comprising at least a shaft (4) and a nipple (2), 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 (7) having a surface roughness of 100 μm at the most, in particular of 50 μm at the most.

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 disposed within the mouthpiece. An exterior surface of the inner core is spaced from an interior surface of the mouthpiece at the position of a fluid pocket guiding face of the exterior surface of the inner core so that a fluid duct between the mouthpiece and the inner core 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 of the inner core has at least one protrusion that is designed to form a fluid barrier between the mouthpiece and the inner core at a position for delimiting the fluid duct at the sides thereof.

A device for heating and concomitantly administering a liquid includes a body having at opposite ends a base and a neck connectable to liquid suction means, and liquid heating means. The body has an inner housing configured to receive and completely enclose a liquid container. The inner housing has fluidic connection means. The neck has one or more tubes adapted to fluidically connect the fluidic connection means to the liquid suction means. The liquid heating means are adapted to heat at least partially the one or more tubes, and the fluidic connection means have one or more sharp spouts for puncturing of a predetermined region of the liquid container and for fluidic connection to the liquid container. A liquid container and a sanitizing system of the device are also provided.
