摘要

The tube forms part of the upper part (8) as fixed to the container and the pump dome (10) is sealably fixed to the top rim (9) of the upper part specified. The tube is angled round from its outlet towards the diaphragm. The upper part has a flap-down lid hinged to it and an endstop (13) is at set spacing above the tube within the dome. A bottom air hole (15) is inserted in the bottom part outside the suction space (14) to communicate with the container interior. A flexible diaphragm is arranged between the dispenser tube (3) opening (2) towards the container (1) and the upwards opening (4) of the container bottom part (6) neck (5).
