Abstract

The invention relates to a flexible container (10) for dispensing liquid from a delivery aperture (12) on the closure part (14), a venting valve (18) being assigned to a venting aperture (90) of the container (10), which venting valve is opened in the case of negative pressure in the container (10). The closure part (14) is arranged on a metering body (20) which is inserted in a sealing manner in the opening of the container (10) and is provided with two outlet channels (24, 26). The outlet channels (24, 26) serve to deliver the liquid in the form of a jet or of droplets and, by turning the closure part (14), can be connected selectively to the delivery aperture (12) of the closure part (14). The liquid is located in an internal bag (50) which communicates via a shut-off valve (64, 66) in each case with the outlet channels (24, 26). When the container (10) is turned upside down, the liquid can be delivered by squeezing the container walls in the form of droplets or of a jet in dependence on the position of the closure part (14) by opening the corresponding non-return valve (64, 66) whilst the venting valve (18) remains closed. The relevant non-return valve closes automatically while the venting valve opens when the pressure on the container walls is removed. <IMAGE>

Die US-PS 44 01 270 beschreibt eine Sprühvorrichtung für eine Quetschflasche, die zur Abgabe eines Sprühstrahls eines Stromes und zum Verschließen der Flasche vorgesehen ist. Ein Verschlußkörper für die Flasche weist Durchgangskanäle auf, wobei ein Durchgangskanal für Luft nahe einer Mischkammer vorgesehen ist. Die Flüssigkeit wird durch ein Tauchrohr und Zuführkanäle anschliessend in die Seite eines Luftstroms geleitet, so daß die Flüssigkeit durch die entstehende Turbulenz aufgebrochen wird. Nach der Vermischung fließt der Sprühstrahl durch eine Öffnung in einen Ring. Der Ring kann verstellt werden, um die Mischkammer zu verschliessen und die Austrittsöffnung mit einem Flüssigkeitskanal in Deckung zu bringen, so daß ein konstanter Flüssigkeitsstrom aus dem Behälter abgegeben wird, oder es kann der Ring so verstellt werden, daß sämtliche Kanäle gesperrt sind.The US-PS 44 01 270 describes a spray device for a squeeze bottle, which is provided for delivering a spray jet of a stream and for closing the bottle. A closure body for the bottle has through channels, wherein a through channel for air is provided near a mixing chamber. The liquid is then passed through an immersion tube and feed channels into the side of an air stream, so that the liquid is broken up by the turbulence that arises. After mixing, the spray flows through an opening into a ring. The ring can be adjusted to close the mixing chamber and to cover the outlet opening with a liquid channel so that a constant flow of liquid is dispensed from the container, or the ring can be adjusted so that all channels are blocked.

1 shows a container 10 made of plastic with flexible, hand-compressible side walls for dispensing a liquid from a dispensing opening 12 of a closure part 14 of the container 10. The discharge opening 12 of the closure part 14 is formed by a discharge nozzle 36, which is eccentric and parallel to the main axis of the container 10. The closure part 14 is provided with a jacket 38, the inside of which has a circumferential locking groove 40.

Ein Dosierkörper 20 ist in einen Hals 44 eines kappenförmigen Behälterverschlusses 46 eingesetzt. Ein oberes Ende und ein unteres Ende des Dosierkörpers 20 ragen über die entsprechenden Enden des genannten Halses 44 hinaus nach oben bzw. nach unten vor. Das obere Ende des Dosierkörpers 20 weist an seinem Umfang einen sich nach oben kegelstumpfförmig verjüngende Rastwulst 42 auf, den das Verschlußteil 14 mit seinem kappenförmigem Mantel 38 übergreift, so daß der Rastwulst 42 in die Rastnut 40 eingreift und das Verschlußteil 14 auf dem Dosierkörper 20 dicht, aber um eine Hauptachse des Dosierkörpers 20 verdrehbar gehalten ist.A dosing body 20 is inserted into a neck 44 of a cap-shaped container closure 46. An upper end and a lower end of the dosing body 20 protrude the corresponding ends of said neck 44 forward or downward. The upper end of the dosing body 20 has on its circumference an upwardly frustoconical locking bead 42 which the closure part 14 engages with its cap-shaped jacket 38, so that the locking bead 42 engages in the locking groove 40 and the closure part 14 on the dosing body 20 is sealed , but is held rotatable about a main axis of the metering body 20.

Der Dosierkörper 20 ist mit einem ersten Auslaßkanal 24 und einem zweiten Auslaßkanal 26 versehen. Der erste Auslaßkanal 24 ist glattzylindrisch ausgebildet und dient zur Abgabe von Flüssigkeit in Form eines Strahles. Dagegen weist der zweite Auslaßkanal 26 in Strömungsrichtung der Flüssigkeit zunächst einen ersten Längenabschnitt 34 auf, der sich über etwa ein Drittel der Höhe des Dosierkörpers 20 erstreckt. An diesen Längenabschnitt 34 schließt sich in Strömungsrichtung der Flüssigkeit ein zweiter Längenabschnitt 28 des zweiten Auslaßkanals 26 an, dessen Querschnitt wesentlich größer als derjenige des ersten Längenabschnitts 34 bemessen ist. Dieser zweite Auslaßkanal 26 dient zur Abgabe von Flüssigkeit in Form von Tropfen. Zu diesem Zweck wird das Längen- und Durchmesserverhältnis des ersten, engeren Längenabschnitts 34 zu dem zweiten, erweiterten Längenabschnitt 28 des zweiten Auslaßkanals 26 so gewählt, daß die Fließgeschwindigkeit der Flüssigkeit in den erweiterten Längenabschnitt 28 des zweiten Auslaßkanals 26 geringer als die Austropfgeschwindigkeit der Flüssigkeit aus dessen erweitertem Längenabschnitt 28 bemessen ist.The metering body 20 is provided with a first outlet channel 24 and a second outlet channel 26. The first outlet channel 24 is of smooth cylindrical design and serves to dispense liquid in the form of a jet. In contrast, the second outlet channel 26 initially has a first length section 34 in the flow direction of the liquid, which extends over approximately one third of the height of the metering body 20. This length section 34 is adjoined in the flow direction of the liquid by a second length section 28 of the second outlet channel 26, the cross section of which is dimensioned substantially larger than that of the first length section 34. This second outlet channel 26 serves to dispense liquid in the form of drops. For this purpose, the length and diameter ratio of the first, narrower length section 34 to the second, extended length section 28 of the second outlet channel 26 is selected such that the flow rate of the liquid into the extended length section 28 of the second outlet channel 26 is lower than the dropping speed of the liquid whose extended length section 28 is dimensioned.

Die beiden Auslaßkanäle 24, 26 sind parallel zueinander und zur senkrechten Hauptachse des Dosierkörpers 20 ausgerichtet und liegen jeweils mit ihren Auslaßöffnungen 30 bzw. 32 in einem Winkelabstand auf einem Kreis, den die Abgabeöffnung 12 beschreibt, wenn das Verschlußteil 14 auf dem Dosierkörper 20 gedreht wird. Infolgedessen kann das Verschlußteil 14 wahlweise zwischen einer Schließstellung und zwei Offenstellungen über den Auslaßöffnungen 30, 32 verdreht werden.The two outlet channels 24, 26 are aligned parallel to one another and to the vertical main axis of the metering body 20 and each lie with their outlet openings 30 and 32 at an angular distance on a circle which the discharge opening 12 describes when the closure part 14 is open the dosing body 20 is rotated. As a result, the closure part 14 can optionally be rotated between a closed position and two open positions via the outlet openings 30, 32.

Das untere Ende des Dosierkörpers 20 greift abdichtend in die Öffnung eines Halses 22 eines verformbaren Innenbeutels 50 ein, in welchem die abzugebende Flüssigkeit enthalten ist. Von dem Umfangsrand einer unteren Stirnseite 48 des Dosierkörpers 20 stehen Zentrierzungen 54 axial vor, deren Zweck nachstehend erläutert wird.The lower end of the metering body 20 sealingly engages in the opening of a neck 22 of a deformable inner bag 50, in which the liquid to be dispensed is contained. Centering tongues 54 project axially from the peripheral edge of a lower end face 48 of the metering body 20, the purpose of which is explained below.

Die untere Stirnseite 48 des Dosierkörpers 20 liegt auf einer oberen Stirnseite 52 eines Ventilkörpers 60 auf, der ebenfalls in den Hals 22 des Innenbeutels 50 abdichtend eingesetzt ist und den gleichen Durchmesser aufweist wie der Dosierkörper 20. Am Außenumfang der oberen Stirnseite 52 des Ventilkörpers 60 sind Zentrierausnehmungen 56 vorgesehen, in welche die Zentrierzungen 54 des Dosierkörpers 20 genau passend eingreifen. Dabei können die Zentrierausnehmungen 56 und die Zentrierzungen 54 paarweise unterschiedliche Abmessungen oder Winkelabstände aufweisen, so daß bei der Montage zwangsläufig die gewünschte Montagestellung von Dosierkörper und Ventilkörper und damit die Flüssigkeitsverbindung zwischen dem Innern des Innenbeutels 50 und den Auslaßöffnungen 30, 32 des Dosierkörpers 20 sichergestellt ist.The lower end face 48 of the metering body 20 rests on an upper end face 52 of a valve body 60, which is also sealingly inserted into the neck 22 of the inner bag 50 and has the same diameter as the metering body 20. On the outer circumference of the upper end face 52 of the valve body 60 Centering recesses 56 are provided, in which the centering tongues 54 of the metering body 20 engage in a precisely fitting manner. The centering recesses 56 and the centering tongues 54 can have different dimensions or angular spacings in pairs, so that the desired mounting position of the metering body and valve body and thus the fluid connection between the inside of the inner bag 50 and the outlet openings 30, 32 of the metering body 20 is inevitably ensured during assembly .

Zur Herstellung dieser Flüssigkeitsverbindung mit den Auslaßkanälen 24, 26 des Dosierkörpers 20 sind im Ventilkörper 60 zwei Durchtrittskanäle 58, 62 vorgesehen, die, wie Fig. 1 zeigt, mit dem ersten Auslaßkanal 24 bzw. dem zweiten Auslaßkanal 26 des Dosierkörpers 20 fluchten. Diese Durchtrittskanäle 58, 62 sind nach oben zu einer Ventilkammer 59, 61 erweitert. In den Ventilkammern 59, 61 ist jeweils eine Ventilkugel 68, 70 eines Absperrventils 64, 66 angeordnet, die auf einem Ventilsitz 72, 74 durch Druckfedern 76, 78 gehalten sind und daher normalerweise die Durchtrittskanäle 58, 62 des Ventilkörpers 60 abdichten. Die oberen Enden der Druckfedern 76, 78 liegen an der unteren Stirnseite 48 des Dosierkörpers 20 so an, daß die Druckfedern 76, 78 in der zugehörigen Ventilkammer 59, 61 unter einer gewissen Vorspannung stehen.To establish this fluid connection with the outlet channels 24, 26 of the metering body 20, two passage channels 58, 62 are provided in the valve body 60, which, as shown in FIG. 1, are aligned with the first outlet channel 24 and the second outlet channel 26 of the metering body 20. These passage channels 58, 62 are expanded up to a valve chamber 59, 61. In the valve chambers 59, 61 a valve ball 68, 70 of a shut-off valve 64, 66 is arranged, which are held on a valve seat 72, 74 by compression springs 76, 78 and therefore normally seal the passage channels 58, 62 of the valve body 60. The upper ends of the compression springs 76, 78 rest on the lower end face 48 of the metering body 20 so that the compression springs 76, 78 are under a certain pretension in the associated valve chamber 59, 61.

Der Behälterverschluß 46 ist mit einer äußeren Ringschulter 82 versehen, in der eine Belüftungsöffnung 90 vorgesehen ist und die den Hals 44 des Behälterverschlusses 46 mit einem sich abwärts erstreckenden Verschlußmantel 84 verbindet. Der Behälter 10 ist mit einem durch eine Außenschulter 86 abgesetzten Hals 88 versehen, auf den der Behälterverschluß 46 passend aufgesetzt ist. Wie Fig. 1 zeigt, bilden die Außenflächen des Verschlußmantels 84 und des Behälters 10 eine glatte, im wesentlichen nahtlose Oberfläche der Packung, weil die Wandstärke des Verschlußmantels 84 der Breite der Außenschulter 86 entspricht.The container closure 46 is provided with an outer annular shoulder 82, in which a ventilation opening 90 is provided and which connects the neck 44 of the container closure 46 to a downwardly extending closure jacket 84. The container 10 is provided with a neck 88 which is offset by an outer shoulder 86 and onto which the container closure 46 is fitted. 1, the outer surfaces of the closure shell 84 and the container 10 form a smooth, substantially seamless surface of the package because the wall thickness of the closure shell 84 corresponds to the width of the outer shoulder 86.

In den Behälterhals 88 ist ein Träger 100 abdichtend eingepaßt, dessen Kopfwand 101 eine ebenflächige, horizontale Oberseite 103 aufweist, die mit der Stirnfläche des Behälterhalses 88 fluchtet. Eine Unterseite der Kopfwand 101 ist in Höhe einer Innenschulter 102 angeordnet, welche von dem Behälterhals 88 gebildet ist. Von der Unterseite der Kopfwand 101 steht eine ringförmige Wand 104 nach unten vor und umschließt abdichtend die äußere Oberfläche des Beutelhalses 22. Dabei deckt die Unterseite der Kopfwand 101 die Stirnfläche des Beutelhalses 22 dicht ab. Die Kopfwand 101 hat eine mittlere Öffnung, die von einem Rand 106 umgeben ist, der dicht an der Umfangsfläche des unteren Endes des Dosierkörpers 20 anliegt und die Stirnfläche des Halses 22 des Innenbeutels 50 abdeckt.A carrier 100 is sealingly fitted into the container neck 88, the top wall 101 of which has a flat, horizontal upper side 103 which is flush with the end face of the container neck 88. An underside of the head wall 101 is arranged at the level of an inner shoulder 102, which is formed by the container neck 88. An annular wall 104 projects downward from the underside of the top wall 101 and sealingly surrounds the outer surface of the bag neck 22. The underside of the top wall 101 tightly covers the end face of the neck 22 of the bag. The top wall 101 has a central opening which is surrounded by an edge 106 which lies closely against the peripheral surface of the lower end of the dosing body 20 and covers the end face of the neck 22 of the inner bag 50.

Der Träger 100 nimmt das Belüftungsventil 18 auf. Zu diesem Zweck ist die Kopfwand 101 des Trägers 100 mit einer Belüftungsöffnung 16 versehen, die mit der Belüftungsöffnung 90 des Behälterverschlusses 46 fluchtet. Die Belüftungsöffnung 16 erweitert sich zum Innern des Behälters 10 hin und bildet einen konischen Ventilsitz 108 für eine Ventilkugel 110, die durch radial nach innen vorspringende Tragarme 112 normalerweise in der Offenstellung des Belüftungsventils 18 abgestützt ist. Da zwischen den Tragarmen 112 in Umfangsrichtung der Ventilöffnung Zwischenräume vorgesehen sind, kann in der in Fig. 1 gezeigten Offenstellung des Belüftungsventils 18 Luft zwischen der Ventilkugel 110 und den Tragarmen 112 hindurchströmen, so daß ein Zwischenraum 113 zwischen der Wandung des Behälters 10 und der Außenseite des Innenbeutels 50 ständig belüftet ist. Wird zur Betätigung des Behälters 10 dessen flexible Wandung von Hand zusammengedrückt, wird die Ventilkugel 110 nach oben bewegt und gegen ihren Ventilsitz 108 gepreßt, so daß das Belüftungsventil 18 geschlossen ist. Beim weiteren Zusammendrücken der Behälterwandung wird der aus weichem, aber flüssigkeitsdichtem Material bestehende Innenbeutel 50 komprimiert, so daß die im Innenbeutel enthaltene Flüssigkeit eines der beiden Absperrventile 64 oder 66 öffnet, wenn das Verschlußteil 14 sich in einer seiner Öffnungsstellungen befindet. Durch eine Überkopflage der Packung wird die Flüssigkeitsabgabe erheblich erleichtert.The carrier 100 receives the ventilation valve 18. For this purpose, the top wall 101 of the carrier 100 is provided with a ventilation opening 16 which is flush with the ventilation opening 90 of the container closure 46. The ventilation opening 16 widens towards the interior of the container 10 and forms a conical valve seat 108 for a valve ball 110, which is normally supported by radially inwardly projecting support arms 112 in the open position of the ventilation valve 18. Since gaps are provided between the support arms 112 in the circumferential direction of the valve opening, in the open position of the ventilation valve 18 shown in FIG. 1, air can flow between the valve ball 110 and the support arms 112, so that a gap 113 between the wall of the container 10 and the outside of the inner bag 50 is constantly ventilated. If the flexible wall of the container 10 is compressed by hand, the valve ball 110 is moved upwards and pressed against its valve seat 108, so that the ventilation valve 18 is closed. When the container wall is further compressed, the inner bag 50, which is made of soft but liquid-tight material, is compressed, so that the liquid contained in the inner bag opens one of the two shut-off valves 64 or 66 when the closure part 14 is in one of its open positions. The liquid dispensing is considerably facilitated by an upside-down position of the pack.

In den Fig. 2 und 3 ist der Dosierkörper 20 näher dargestellt. Fig. 2 zeigt, daß die Auslaßkanäle 24, 26 in einem Winkelabstand von 90° zueinander versetzt sind, aber im gleichen radialen Abstand zur Hauptachse des Dosierkörpers 20 auf einem hierzu konzentrischen Kreis angeordnet sind. In der oberen Stirnseite des Dosierkörpers 20 ist ferner eine Begrenzungsnut 80 eingelassen, die konzentrisch zur Hauptachse sich über einen Winkel von 90° erstreckt.2 and 3, the dosing body 20 is shown in more detail. Fig. 2 shows that the outlet channels 24, 26 are offset from one another by 90 °, but are arranged at the same radial distance from the main axis of the dosing body 20 on a concentric circle. In the upper end face of the metering body 20 there is also a limiting groove 80 which extends concentrically to the main axis over an angle of 90 °.

Fig. 4 und 5 zeigen das Verschlußteil 14 als Abgabekopf, der dem Dosierkörper 20 angepaßt ist. Das Verschlußteil 14 besteht aus einer Abdeckplatte 92, welche die Abgabeöffnung 12 in dem Abgabestutzen 36 durchsetzt. Der sich abwärts erstreckende Mantel 38 ist am unteren Ende mit der inneren Rastnut 40 versehen, die unter den äußeren Rastwulst 42 des Dosierkörpers 20 unter Schnappwirkung greift, wenn das Verschlußteil 14 auf den Dosierkörper 20 aufgesetzt wird. Das Verschlußteil 14 liegt mit seiner Unterseite 94 dicht auf einer oberen Stirnfläche 96 des Dosierkörpers 20 auf.4 and 5 show the closure part 14 as a dispensing head which is adapted to the dosing body 20. The closure part 14 consists of a cover plate 92 which passes through the discharge opening 12 in the discharge nozzle 36. The downwardly extending jacket 38 is provided at the lower end with the inner locking groove 40, which engages under the outer locking bead 42 of the dosing body 20 with a snap action when the closure member 14 is placed on the dosing body 20. The closure part 14 lies with its underside 94 tightly on an upper end face 96 of the dosing body 20.

Von der Unterseite 94 des Verschlußteils 14 steht ferner ein Anschlagnocken 98 vor, der in die Begrenzungsnut 80 an der Oberseite des Dosierkörpers 20 beweglich eingreift, derart, daß das Verschlußteil 14 mit dem Anschlagnocken 98 um 90° jeweils in die beiden Endstellungen in der Begrenzungsnut 80 verdrehbar ist, wobei die Abgabeöffnung 12 entweder mit dem Auslaßkanal 24 oder dem Auslaßkanal 26 in Verbindung steht. Fig. 4 und 5 zeigen, daß die Abgabeöffnung 12 und der Anschlagnocken 98 auf einem Kreis diametral gegenüberliegend angeordnet sind, der zur Hauptachse des Dosierkörpers 20 konzentrisch angeordnet ist.From the underside 94 of the closure part 14 there is also a stop cam 98, which engages movably in the limiting groove 80 on the upper side of the metering body 20, such that the closure part 14 with the stop cam 98 is at 90 ° in each of the two end positions in the limiting groove 80 is rotatable, the discharge opening 12 being connected either to the outlet channel 24 or to the outlet channel 26. 4 and 5 show that the discharge opening 12 and the stop cam 98 are arranged diametrically opposite one another on a circle which is arranged concentrically to the main axis of the dosing body 20.

Es ist somit ersichtlich, daß das Verschlußteil 14 zwischen den Abgabestellungen für Tropfen bzw. für einen Sprühstrahl und einer Schließstellung von Hand verstellbar ist, in der sich die Abgabeöffnung 12 zwischen den Auslaßkanälen 24, 26 befindet.It can thus be seen that the closure part 14 can be adjusted manually between the dispensing positions for drops or for a spray jet and a closed position in which the dispensing opening 12 is located between the outlet channels 24, 26.
