ABSTRACT:
A device for the apportioned delivery of liquid (3) from a storage container (2) through an outlet tube (20) which enters into the low position, the delivery taking place only upon the second turning over the device. A cup-shaped housing (5) is divided by a partition wall (16) into an upper chamber (I) and a lower discharge chamber (II), the discharge chamber (II) and upper chamber (I) of the housing being connected to each other by a passage hole (17), and a feed opening (33) is formed in the upper chamber (I). An outlet tube (20) debouches above the partition wall (16), and an air passage is formed in the region of the upper chamber (I). In order to obtain a more advantageous development from a manufacturing standpoint while retaining or possibly even increasing the accuracy of dosaging, the outlet tube (20) is attached to the upper chamber (I) and the discharge chamber (II) is attached by detent to the upper chamber (I).
