La section gobelet (1) forme un espace fermé entre un sein et la section gobelet (1). Le premier tuyau (10) est relié à l'espace fermé. Le premier tuyau (10) comprend le premier récipient (11), qui stocke le lait. L'ouverture d'admission (31) de la pompe piézoélectrique (30) est reliée au premier tuyau (10). La pompe piézoélectrique (30) aspire l'air à l'intérieur de l'espace fermé par l'intermédiaire de l'ouverture d'admission (31), générant une pression négative dans l'espace fermé. Le second tuyau (20) est relié à l'espace à l'intérieur du premier récipient (11). Une tétine artificielle (9) est prévue à l'extrémité du tube (5). Le second tuyau (20) comprend le second récipient (21), qui stocke le lait arrivant dans celui-ci, en provenance du premier récipient (11) via le tuyau (4).
