  • 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).

  • Patent number: 5301846
    Abstract: The invention relates to a flexible spray bottle (10) for nasal spray, onto the bottle neck (14) of which a spray cap (12) is placed. The top wall (17) of the spray cap (12) contains a spray opening (20) and, on the underside, a connection piece (18) for a dip tube (21). A mixing-air passage (30, 31) extends between the connection piece (18) and the dip tube (21), with the result that a liquid/air mixture leaves the spray opening (20). An annular flange (15) of the spray cap (12) contains an air-admitting passage (23) which extends radially in the flange and is angled inside the spray cap towards the interior of the bottle (10). The angled part contains an air-admitting valve with a valve body (28) which is pressed against a valve seat (27) in the case of positive pressure in the container and seals off the air-admitting passage (23). In the open position of the air-admitting valve, the valve body (28) rests on supporting arms (29) which make possible the passage of air through the air-admitting passage (23).

  • Patent number: 5249713
    Abstract: Package comprising a liquid receptacle and a hand pump arranged thereon, the actuating and dispensing head of which, which can be operated counter to the action of a compression spring, is provided with an outlet opening for the liquid. A protective cap is detachably secured on the upper side of the liquid receptacle. Secured swivelably in the protective cap is a pump-actuated lever. The actuating lever extends from its swiveling spindle in the protective cap to beyond the dispensing head of the pump. The free lever end is angled in the direction of the receptacle lid. The protective cap is provided in the region of the free lever end with an opening into which the actuating lever at least projects. At the top, the dispensing head is connected with the actuating lever in such a way that it is non-rotatable but axially movable; its outlet opening is in alignment with a passage opening in the protective cap. The package is easy to handle and space-saving.

  • Patent number: 5240149
    Abstract: The invention relates to a closure cap (5) having a dispensing opening (6) for containers with flexible walls, which can be pressed together by hand for the dispensing of spray product which is in connection with the dispensing opening (6) by means of a dip tube (7). Upstream of the dispensing opening (6) is an outlet valve (8), which is open when there is positive pressure in the container, whereas an air-admitting opening (9) is assigned an air-admitting valve (10), which is open when there is negative pressure in the container. By virtue of the outlet valve (8) upstream of the dispensing opening (6), the readmission of air to the container and consequently the risk of sucking in through the dispensing opening (6) substances contaminating the container content is prevented.
