The invention relates to a device (V) for dispensing portioned amounts, such as for example a WC cleaning/disinfecting liquid and/or a fragrance, comprising a reservoir (2) in which fluid product (1) is housed. The liquid product (1) forms a first free level (Sp1) and is associated with a closed space (3). The aim of the invention is to produce exactly reproducible portioned amounts of fluid product. Said aim is achieved, whereby the closed space (3) is formed on the upper side of the reservoir (2), a product opening (6) is embodied in the lower region (U) of the reservoir (2), connected to a first receiver basin (10), in which the fluid product (1) forms a second free level (Sp2) at a level closing off the product opening (6) and a second receiver basin (11) is provided, connected to the first receiver basin (10) below the free level (Sp2), comprising an overflow (U) for the dispensing of the portioned amount of fluid product for dosing.
