Abstract
The invention relates to a deformable container (10) for delivering a liquid from a dispensing opening (12) on the sealing part (14), there being assigned to the ventilating opening (90) of the container (10) a ventilating valve (18) which is open in the event of underpressure in the container (10). The sealing part (14) is disposed on a metering element (20), which is inserted sealingly in the opening in the container (10) and is provided with two outlet ducts (24, 26). The outlet ducts (24, 26) serve to dispense the liquid in jet or drop form and can optionally be connected, by twisting the sealing part (14), to the dispensing opening (12) of the sealing part (14). The liquid is located in an inner bag (50), which is connected, in each case via a shut-off valve (64, 66), to the outlet ducts (24, 26). In an overhead position of the container (10), the liquid can be dispensed by compression of the container walls, depending upon the setting of the sealing part (14), in drop or jet form, by the corresponding nonreturn valve (64, 66) being opened whilst the ventilating valve (18) remains simultaneously closed. The nonreturn valve in question closes automatically, whilst the ventilating valve opens whenever the pressure exerted upon the container walls is lifted.
