ABSTRACT:
The invention comprises a synthetic pack, in the filler container (11) of which there is integrated a compression spring element (16), against whose resistance a dispensing head (12) can be moved downwards with its carrier (18) of the filler container (11) and the filler can be pressurized. A ventilation valve (50) is herewith closed prior to the opening of a dispensing valve (22), which is circuit-connected into a product duct formed by a lifting tube (15) and product ducts (27, 40, 14). The dispensing head (12) is sealtight on the carrier (18) of the filler container (11), but is twistable between a closed position and an open position, the product duct (14, 40) of the dispensing head (12), in the open position, being aligned with the product duct (27) in a lifting tube nipple (20) and the ventilation valve (50) of the dispensing head (12) being aligned with a ventilation opening (29) in a headplate (19) of the carrier (18). With the pack (10), a high spraying quality is obtained, in conjunction with convenient handling, the dispensing head (12) simultaneously forming a transport seal for the pack.
