Claim 15:
16. A teat for use with a container for containing a fluid, the teat comprising:
a deformable mouthpiece for an infant to suck on during a fluid intake action, the mouthpiece defining at least one aperture for allowing the fluid to flow out of the teat:
an inner core disposed within the mouthpieces wherein an exterior surface of the inner core comprises a single fluid pocket guiding face that is spaced from an interior surface of the mouthpiece and extends along a length of the inner core so that a fluid duct between the mouthpiece and the fluid pocket guiding face is defined which allows the infant to perform a peristaltic fluid intake action during which the mouthpiece is deformed and the fluid is forced along the fluid duct in a direction towards the at least one aperture of the mouthpiece, and
at least one valve located within the mouthpiece at a level of the inner core, and configured to allow the fluid to flow through the fluid duct in one direction out of the teat and to resist a flow of fluid in the opposite direction,
wherein at least one of the interior surface of the mouthpiece or the exterior surface of the inner core has protrusions at least at edges of the fluid pocket guiding face and configured to form a fluid barrier between the mouthpiece and the inner core at a position for delimiting the fluid duct at sides thereof, such that the fluid harrier is configured to prevent leakage of the fluid from between the mouthpiece and the inner core at the edges of the fluid pocket guiding face, thus sealing the fluid duct in a sideward direction,
whereby the fluid follows a path of travel along the fluid pocket guiding face during use.
