An arrangement for emptying a bag-like envelope (11) containing a pasty liquid (12) consists substantially of a rigid housing (13) for the envelope and an axially movable piston (10) for compressing the envelope (11) and for discharging the liquid (12) through a discharge opening (14) in the housing. The piston comprises on its outer edge (15) at least one scraping element (16) which is movable between an insertion position (I), and a scraping position (S). In the insertion position (I), the scraping edge (17) of the scraping element (16) is spaced from the inner surface (19) of the housing (13). In the scraping position (S), the scraping edge (17) is pressed against the inner surface (19) of the housing (13).
