Abstract: A pacifier of the dummy type comprises a bubble body (18) on which the child sucks, and a stop disc (16) against which the child's lips (22, 24) rest supportingly in the pacifier's position of use. The bubble body (18) and the stop disc (16) are interconnected through an intermediate transition and connecting portion (20) accommodating possible front teeth (26, 28)/gums. The bubble body (18) is given an asymmetrical shape in respect of its connection point on the transition and connecting portion (20), comprising at least one elongate leg (18a) sloping downwardly in its longitudinal direction towards the free end thereof, forming an impact and support face for the adjacent portion of the tongue (34). The stop disc (16) comprises an upper and a lower portion (16a, 16b) somewhat displaced from each other in the longitudinal axial direction of the pacifier, forming suitable stop and support faces for the child's lips (22, 24).
