Teat for use with a container for containing liquid

A teat for use with a container for containing liquid, the teat comprising:

• a hollow teat body including a deformable hollow mouthpiece for a user of the teat to suck on during a liquid intake action to displace liquid in a downstream direction through the teat body and out of the teat through the mouthpiece;
• and
• a normally-closed valve arranged at a level of the mouthpiece, the normally-closed valve being adapted to open under an influence of suction forces exerted to the mouthpiece by the user of the teat during the liquid intake action, and the normally-closed valve being included in a valve area of a valve body that is configured and arranged to prevent the normally-closed valve from being opened under the influence of compression forces on the mouthpiece inflicted by the user of the teat during the liquid intake action, wherein:
• positioning and dimensioning of the valve body provide a radial distance (R) between an outer wall of the valve body and an inside surface of the mouthpiece that is sufficient to substantially prevent the compression forces on an outer wall of the mouthpiece from causing contact between the inside surface of the mouthpiece and the outer wall of the valve body;
• the normally-closed valve is recessed from a top end of the mouthpiece and disposed within the mouthpiece;
• and the valve body is cup-shaped and has a bottom and a wall portion, and wherein the valve body extends in an upstream direction in the mouthpiece from the top end thereof, the bottom of the valve body being located at a most upstream level in the mouthpiece and the valve area being located in the bottom.
