  • Patent number: 5366115
    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).

  • Patent number: 5340031
    Abstract: A foaming head (10) has a discharge nozzle (12), the discharge channel (14) of which has at the upper end a tubular section (16), the upper end of which is closed by a deflecting plate (18) and is provided with passage slits (22) which open out radially into an outlet slit (24) in the head wall (20). An inner base (26) of each outlet slit (24) extends radially outwardly from the lower end (28) of each passage slit (22) as far as a deflecting wall (30) which together with the discharge channel (14) forms an acute angle which opens towards the head wall (20). An upper end (32) of each deflecting wall (30) is arranged at a level which is approximately two-thirds of the height of the tubular section (16). An outer base (34) of each outlet slit (24) extends radially outwardly from the upper end (32) of the deflecting wall (30) as far as the vicinity of an outer edge (36) of the head wall (20).

  • Patent number: 5328060
    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).
