Teat for use with a container for containing a fluid

A teat for use with a container for containing a fluid, comprising:

• a deformable mouthpiece for an infant to suck on during a fluid intake action, the mouthpiece having at least one aperture therein for allowing a fluid to flow out of the teat;
• and
• an inner core disposed within the mouthpiece, wherein 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 extending along a length 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 during which the mouthpiece is deformed and a fluid is forced along the fluid duct in a direction towards the at least one aperture of the mouthpiece, wherein the at least one aperture is arranged in a central front area of the mouthpiece, and wherein the mouthpiece and the inner core are designed to leave space between them for a fluid flow path from the fluid pocket guiding face to the at least one aperture,
• characterized in that the interior surface of the mouthpiece and a middle area of the fluid pocket guiding face which is central as seen in a peripheral direction of the teat are further offset from each other along a front part of the fluid pocket guiding face than towards an adjacent part of the fluid pocket guiding face that is more to the back.
