Abstract: A method for the production of a filled metering pump arrangement fills a product capable of flow into a film bag, which is accommodated in a container. The film bag and the container are closed by means of a pump that can be activated manually, which blocks a fluid connection between an outlet opening and the interior of the film bag, in the unstressed state, by means of at least one kick-back valve. Furthermore, the gas situated in the film bag is removed, at least approximately completely, by having at least one feed channel remain open in the container after it has been closed by the pump. By means of the at least one feed channel, a fluid that is under pressure is introduced into the container so that the film bag is compressed in the container and as a result, the gases situated in the film bag are ejected from it through the pump and/or through a bypass channel that circumvents it.

Abstract: A method for the production of a filled metering pump arrangement fills a product capable of flow into a film bag, which may be received in a container, for example. The film bag is closed by means of a pump that can be activated manually, which blocks a fluid connection between an outlet opening and the interior of the film bag, in the unstressed state, by means of at least one kick-back valve. The gas situated in the film bag is removed, at least substantially completely, by compressing the film bag, particularly by means of a punch or similar device.

Abstract: A device for dispensing fluids from a sealed off-storage container includes a housing placed on the container that receives a pressure cylinder for insertion in the container. The cylinder has a pressure chamber defined at the upper end by a piston guided in the cylinder and at the lower end by a valve. The valve acts upon the container and is closed when there is an excess pressure and opens when there is a negative pressure in the chamber. The piston has a pump channel linked with the chamber, and the cylinder has openings upstream of the chamber for drawing off residual air present in the container. A passage between an outer wall of the piston and an inner wall of the cylinder upstream of the openings is closed by a sealing washer. Residual air is drawn off via the openings and the passage, whereby the sealing washer loses its sealing effect on the piston.

Abstract: A valve for a pressurized dispenser which includes, within a mounting cup, a valve housing and an annular gasket clamped between the cup and the housing for sealing a discharge passage of a movable valve stem, and which incorporates a clearance space in the cup around the outer marginal portion of the gasket to accommodate the marginal portion when the gasket is stretched during the filling of the dispenser to provide a flow path to the outside of the housing, and which has spacers spaced apart around the periphery of the gasket to define the distance between the cup and the housing within which the gasket is clamped, and between which the stretched gasket extends.
