Pack for free-flowing filler

A pack having a handpump for dispensing free-flowing filler, having a filler container on which there is movably disposed, for the actuation of the pump, a dispensing head, which is provided with an outlet opening linked by a product duct and a lifting tube to the interior of the filler container, wherein a compression spring element forms an integral component part of the filler container and is effective, with a view to stretching the said container, in the longitudinal direction of the latter;

• a carrier for the dispensing head is mounted in a sealtight manner onto the opening of the filler container and is provided with a headplate on whose underside there is disposed, eccentrically to the principal axis of the filler container, a lifting tube nipple to which the upper end of the lifting tube is connected and whose product duct extends through the headplate;
• assigned to the lifting tube nipple is a dispensing valve, which is open whenever the pressure in the filler container lies above the pressure of the external atmosphere;
• the headplate is provided with a pass-through opening for operating air and with a pass-through opening for ventilating air, which are disposed eccentrically to the principal axis of the filler container;
• the dispensing head is disposed in a sealtight manner on the top side of the carrier, but so as to be rotatable between a closed position and an open position, and exhibits on its underside an inlet connecting socket with a product duct which, in the dispensing position of the dispensing head, is aligned with the product duct of the lifting tube nipple and which extends from the upper end of the inlet connecting socket radially outwards up to a dispensing opening in a contacting surface of the dispensing head;
• an operating air duct in the dispensing head extends parallel to the radial product duct up to its dispensing opening;
• a nozzle exhibits an outlet opening and is mounted onto the dispensing opening of the dispensing head, the nozzle being provided on its rear side with a centrifugal chamber, into which the operating air duct opens out and which is connected to the outlet opening of the nozzle;
• a ventilation duct in the dispensing head is aligned with the ventilation opening in the headplate of the carrier in the operating position of the dispensing head and is provided with a ventilation valve, which is open in the event of underpressure in the filler container.
