  • Publication number: 20220110834
    Abstract: A teat (1) comprises a hollow teat body (10) including a deformable hollow mouthpiece (11) and a normally-closed valve (30) arranged at a level of the mouthpiece (11) or a level more downstream, the valve (30) being openable under the influence of suction forces exerted to the mouthpiece (11) by a user of the teat (1) during a liquid intake action. The valve (30) is included in a valve area (32) of a valve body (31) that is configured and arranged to prevent a closed-opened condition of the valve (30) from being changed under the influence of deformation of the mouthpiece (11) inflicted by a user of the teat (1) during a liquid intake action, so that the closed-opened condition of the valve (30) is controllable by means of suction forces exerted to the mouthpiece (11) by a user of the teat (1) during a liquid intake action.
