Abstract: 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).

Abstract: The present application relates to a mouthpiece (20) for an infant feeding vessel (10). The vessel (10) has a mounting collar (60) configured to be received between a receptacle (30) for holding fluid and a connector (40) for mounting the mouthpiece (20) to the receptacle (30) when assembled. The vessel (10) also has an air valve (70) in the mounting collar (60) to allow the flow of air into the receptacle (30) when the mouthpiece (20) is mounted to the receptacle (30). The air valve is biased towards an open condition in its un-assembled state. At least part of the mounting collar (60) is resilient and is configured to be received between the receptacle (30) and the connector (40) when assembled.
