The neck of the container has arranged therein a tightly fitting insert comprising a bottom which is closed in an initial state and which, prior to the activation of a pump engaging with its end section into the insert, is opened in that a housing part of the pump is screwed forwardly in the axial direction of the container. The bottom of the insert and the pump have provided thereinbetween a receiving chamber for an active substance which, after the bottom has been opened, is mixed with a liquid contained in the container. A liquid drug containing an active substance which has no long-time stability can thus be discharged with a vacuum pump after a long storage period.
