  • Patent number: 11857500
    Abstract: 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.
