Abstract:
1. A discharge device being designed as a multiple syringe for discharging a fluid, first product from at least one first container, comprising: a first container in the form of a tube with a dispensing opening and a cylindrical region having a deformable wall; a movable stopper arranged in the tube, said stopper being arranged at the end opposite the dispensing opening and closing said end of the tube; a housing having at least one first chamber which has a first chamber opening and in which the first container is accommodated and at least one second chamber which has a second chamber opening and in which a second product is accommodated; a movable first advancing member for discharging the first product; and a second advancing member which is arranged movably in the second chamber; the first and the second advancing members being connected to each other at a rear end facing away from the first and second chamber opening, in order to prevent a relative motion between the first and the second advancing members, the first advancing member being adapted to be joined to the stopper and being movable within the tube in the direction of the dispensing opening in order to discharge the fluid, first product from the tube, wherein the dispensing opening of the tube is closed by a pierceable covering, wherein, in the discharge device, an opening device which is displaceable relative to the tube is provided, with a puncturing element for piercing the covering, wherein the tube is arranged movably in the first chamber of the discharge device in such a manner that the puncturing element pierces the covering upon movement of the tube in the direction of the first dispensing opening, and wherein the first and the second advancing member are dimensioned in such a manner that, upon joint advancing of the advancing members, the first advancing member moves the tube in the direction of the first dispensing opening, and as a result, the puncturing element pierces the covering of the tube before the second advancing member ejects the second product from the second chamber.
