The drive member is connected to the filling valve inside the container and when filled with a pressurized gas presses against the piston to force material out of the delivery valve. Preferred Features: The piston (18) and drive member (68) are connected. The driving member is folded like a concertina or rolled up in a spiral shape in the lower chamber (22) of the container (12). The delivery valve (14) is a rocker valve and the plate-like valve member (36) has a delivery tube (38) pressed into and sealed in a housing (24) which itself is pressed into the container. Material enters the tube through a radial bore (43) and the valve member (36) presses against a seating face (38a) of the valve housing.

Description

Die Erfindung bezieht sich auf eine Spenderpackung nach dem Anspruch 1.The invention relates to a dispenser package according to claim 1.

Spenderpackungen der unterschiedlichen Ausgestaltung und für die unterschiedlichsten Materialien sind im großem Umfang bekannt. So werden die verschiedensten strömungsfähigen Medien im Kosmetikbereich, bei Putzmitteln, bei Nahrungsmitteln, in der Bauindustrie und dergleichen in Spenderpackungen abgepackt und mit Hilfe geeigneter Abgabe- und Dosiervorrichtungen abgegeben. Besonders verbreitet sind Aerosolpackungen, bei denen einem flüssigen Medium ein Treibgas unter Druck zugemischt ist. Das Austragen des Mediums erfolgt über ein entsprechendes Abgabeventil und ggf. einen sogenannten Sprühkopf. Es ist auch bekannt, das auszutragende Medium in einem Beutel unterzubringen, der mit dem Ausgabeventil verbunden ist und der in einem Behälter untergebracht ist, der seinerseits mit einem Treibmedium gefüllt ist. Das Treibmedium drückt allseitig auf den Beutel und presst auf diese Weise das Medium aus dem Beutel heraus, wenn das Abgabeventil betätigt wird. Eine derartige Packung wird verwendet, wenn vermieden werden soll, dass das gasförmige Treibmittel mit dem auszutragenden Medium in Berührung kommt. Außerdem lassen sich auf diese Weise pastöse Medien mit Hilfe eines gasförmigen Treibmittels austragen. Es ist auch bekannt, bei der zuletzt beschriebenen Packung die Anordnung umzukehren und das Treibmittel in einen Beutel zu füllen und das auszutragende Medium in den den Beutel umgebenden Behälterraum.Dispenser packs of different designs and for the most varied Materials are widely known. So the most varied flowable media in cosmetics, cleaning agents, food, packed in dispenser packages in the construction industry and the like and dispensed with the help of suitable dispensing and metering devices. Especially Aerosol packs are common in which a propellant is used in a liquid medium is mixed under pressure. The medium is discharged via a corresponding one Dispensing valve and possibly a so-called spray head. It is also known to accommodate the medium to be discharged in a bag with the Dispensing valve is connected and housed in a container, which in turn is filled with a propellant. The propellant presses on the all sides Bag and in this way presses the medium out of the bag when that Dispensing valve is operated. Such a package is used when avoided should be that the gaseous propellant with the medium to be discharged comes into contact. In addition, pasty media can be used in this way Discharge using a gaseous blowing agent. It is also known to last described package to reverse the arrangement and the propellant in one Fill bag and the medium to be discharged into the surrounding the bag Container space.

Der Erfindung liegt die Aufgabe zugrunde, eine Spenderpackung für viskoses oder pastöses Material zu schaffen, bei der ebenfalls ein Kontakt zwischen einem gasförmigen Treibmittel und dem auszutragenden Material verhindert wird.The invention has for its object a dispenser pack for viscous or to create pasty material in which also a contact between a gaseous Propellant and the material to be discharged is prevented.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

Bei der erfindungsgemäßen Packung unterteilt ein in einem zylindrischen Behälter gleitend bewegbarer Kolben diesen in einen oberen und einen unteren Raum. Der obere Raum dient zur Aufnahme des auszutragenden Materials, und der untere Raum nimmt ein schlauch- oder beutelförmiges Treiborgan auf, das am Kolben anliegt und mit Treibgas gefüllt ist. Die Füllung erfolgt über ein Befüllventil am unteren Ende des Behälters, mit dessen Gehäuse das Treiborgan verbunden ist. Am oberen Ende des Behälters ist ein herkömmliches Abgabeventil vorgesehen, das nach einer Ausgestaltung der Erfindung als Kippventil ausgebildet sein kann.In the case of the pack according to the invention, one is divided into a cylindrical container slidably movable piston this into an upper and a lower space. The the upper room is used to hold the material to be discharged, and the lower one Space is taken up by a tubular or bag-shaped drive element, which is attached to the piston is present and is filled with propellant gas. The filling takes place via a filling valve on lower end of the container, to the housing of which the drive element is connected. At the A conventional dispensing valve is provided at the top of the container can be designed as a toggle valve according to an embodiment of the invention.

Das Abgabeventil kann vor dem Befüllen des Behälters mit dem abzugebenden Material bereits montiert sein. Es ist daher nicht erforderlich, das Material, ggf. unter Druck, über das Befüllventil in den Behälter einzugeben. Nach dem Befüllen mit dem abzugebenden Material wird der Kolben eingesetzt und das Treiborgan mit dem Befüllventil montiert. Letzteres wird in an sich bekannter Weise wirksam mit dem Behälter dichtend verbunden. Nunmehr wird über das Befüllventil Treibgas in das Treiborgan unter Druck eingeleitet bis zu einem vorgegebenen Druck, wobei die eingefüllte Menge und der Druck ausreichen, den Kolben wirksam bis zum oberen Ende des Behälters zu treiben. Es versteht sich, dass das Befüllventil so angeordnet ist, dass es nicht über das untere Ende des Behälters übersteht, mithin der Behälter aufrecht auf einer Unterlage abgestellt werden kann. Außerdem kann eine Kappe, z.B. aus Kunststoff, auf das untere Ende des Behälters aufgesetzt werden, um das Befüllventil zu schützen und eine ungewollte Betätigung zu verhindern. Ferner wird dadurch das Äußere des Behälters ansprechender.The dispensing valve can be filled with the dispenser before filling the container Material already installed. It is therefore not necessary to under pressure to enter the container through the filling valve. After filling with the material to be dispensed, the piston is inserted and the drive element with the filling valve. The latter becomes effective in a manner known per se sealed to the container. Now propellant gas is in via the filling valve the driving element is introduced under pressure up to a predetermined pressure, the enough quantity and the pressure are sufficient, the piston effectively up to the top Drive end of the container. It is understood that the filling valve is arranged in this way is that it does not protrude over the bottom of the container, hence the container can be parked upright on a surface. In addition, a cap, e.g. made of plastic, to be placed on the lower end of the container To protect the filling valve and to prevent unwanted actuation. Furthermore, thereby making the exterior of the container more appealing.

Das Treiborgan kann aus einer ggf. beschichteten Kunststofffolie gebildet sein, die spiralig gerollt, gefaltet oder in Form eines Ziehharmonikabalges im unteren Raum angeordnet und in geeigneter Weise mit dem Gehäuse des Befüllventils verbunden ist, beispielsweise durch Verschweißen.The drive member can be formed from a possibly coated plastic film spirally rolled, folded or in the form of an accordion bellows in the lower room arranged and connected in a suitable manner to the housing of the filling valve is, for example by welding.

Der Behälter kann aus Blechmaterial oder aus Kunststoff geformt sein. Bei der Verwendung von Blechmaterial wird zumeist ein sogenannter Ventilteller sowohl für das Abgabe- als auch für das Befüllventil vorgesehen, der durch Pressverformung mit dem Rand des Behälters verbunden ist. Wird hingegen ein Kunststoffbehälter vorgesehen, kann zum Beispiel das Befüllventil in geeigneter Weise mit dem Behälterrand verbunden bzw. verschweißt werden. Für das Abgabeventil kann auch vorgesehen werden, das Gehäuse des Befüllventils in eine Öffnung des Behälters einzupressen. Besondere Formvorgänge sind dann nicht erforderlich. Das Ventilgehäuse kann aus elastischem Material bestehen, um in die Behälteröffnung eingepresst zu werden. Anschließend kann ein Abgabeschaft mit Ventilglied in einen Durchgang des Gehäuses eingepresst werdenThe container can be formed from sheet material or from plastic. When using of sheet material is usually a so-called valve plate for both the dispensing as well as the filling valve provided by press forming is connected to the edge of the container. In contrast, becomes a plastic container provided, for example, the filling valve in a suitable manner with the Container edge are connected or welded. For the dispensing valve too be provided, the housing of the filling valve in an opening of the container press in. Special molding processes are then not necessary. The valve housing can be made of elastic material to be pressed into the container opening to become. A dispensing shaft with a valve member can then be inserted into a Passage of the housing

Die Erfindung dient in erster Linie zur Aufnahme von viskosem oder pastösem Material, z.B. Dichtungswerkstoffe, die vor dem Austragen nicht mit Luft in Berührung kommen dürfen, weil sie sonst aushärten und/oder chemisch reagieren. Hierzu gehören ferner PU-Schaum oder PU-Kleber für das Bauwesen, aber auch Kosmetika, Nahrungsmittel oder dergleichen.The invention serves primarily to absorb viscous or pasty Material, e.g. Sealing materials that are not in contact with air before discharge may come because otherwise they harden and / or react chemically. For this also include PU foam or PU glue for construction, but also cosmetics, Food or the like.

Die Erfindung wird nachfolgend anhand eines in Zeichnungen dargestellten Ausführungsbeispiels näher erläutert.The invention is described below using an exemplary embodiment shown in the drawings explained in more detail.

Fig. 1 zeigt einen Schnitt durch eine Packung nach der Erfindung.Fig. 1 shows a section through a pack according to the invention.

Fig. 2 zeigt verkleinert eine Seitenansicht des Treiborgans der Packung. Fig. 2 shows a reduced side view of the drive member of the pack.

In Fig. 1 ist ein zylindrischer Behälter 10 gezeigt, dessen Mantel 12 aus Kunststoff oder Metallblech besteht. Am oberen Ende des Behälters 10 ist ein Abgabeventil 14 vorgesehen und am unteren Ende ein Befüllventil 16. Innerhalb des Behältermantels 12 ist ein als Kunststoffscheibe ausgebildeter Kolben 18 angeordnet. Er ist gleitend und dichtend im Behälter bewegbar und unterteilt das Innere des Behälters in einen oberen Raum 20 zur Aufnahme eines auszutragenden Materials und einen unteren Raum 22. Da der Behälter 10 relativ lang ist, ist aus zeichnerischen Gründen ein Mittelteil nicht gezeigt.In Fig. 1, a cylindrical container 10 is shown, the jacket 12 made of plastic or sheet metal. At the upper end of the container 10 is a dispensing valve 14 provided and at the lower end a filling valve 16. Inside the container shell 12, a piston 18 designed as a plastic disk is arranged. It is sliding and sealingly movable in the container and divides the interior of the container into one upper space 20 for receiving a material to be discharged and a lower one Room 22. Since the container 10 is relatively long, is a for drawing reasons Middle part not shown.

Das Abgabeventil 14 weist ein Gehäuse 24 aus verformbarem Kunststoffmaterial auf. Es ist hülsenartig geformt mit einem unteren radialen Flansch 26 und einer Ringnut 28 oberhalb des Flansches 26. Der Rand einer oberen Öffnung des Behälters 10 sitzt in der Nut 28. Die Öffnung hat einen im Querschnitt kreisbogenförmigen, nach oben gebogenen Rand 32. Das Ventilgehäuse 24 wird in die Öffnung des Behälters 10 eingepresst, wobei der Rand 32 in die Nut 28 einschnappt. Dadurch ist das Gehäuse 24 am Behälter 10 gehalten. Ein tellerförmiges Ventilglied 36 wirkt mit einem unteren Ventilsitz 38a des Gehäuses 24 dichtend zusammen. Mit dem Ventilglied 36 ist ein hohler Schaft 38 einteilig verbunden, der einen radialen Flansch 40 aufweist, der mit dem oberen hülsenförmigen Ende des Gehäuses 24 zusammenwirkt. In der gezeigten Position wird durch das Gehäuse 24 eine gewisse Spannung zwischen Flansch 40 und Ventilglied 36 ausgeübt. Auf diese Weise erfolgt eine ausreichende Abdichtung am Ventilsitz 38a, welche durch den im Raum 20 herrschenden Druck verstärkt wird.The dispensing valve 14 has a housing 24 made of deformable plastic material on. It is shaped like a sleeve with a lower radial flange 26 and one Ring groove 28 above the flange 26. The edge of an upper opening of the container 10 sits in the groove 28. The opening has an arcuate cross section, upwardly bent edge 32. The valve housing 24 is in the opening of the container 10 pressed in, the edge 32 snapping into the groove 28. As a result, the housing 24 is held on the container 10. A plate-shaped valve member 36 cooperates with a lower valve seat 38a of the housing 24 in a sealing manner. With the valve member 36 is integrally connected to a hollow shaft 38 which is radial Has flange 40 which with the upper sleeve-shaped end of the housing 24th cooperates. In the position shown, a certain amount is created by the housing 24 Tension exerted between flange 40 and valve member 36. In this way there is a sufficient seal on the valve seat 38a, which by the in the room 20 prevailing pressure is increased.

Der Schaft 38, der in einen axialen Durchgang des Gehäuses 24 eingepresst ist, sitzt abgedichtet in dem axialen Durchgang, wie z.B. bei 41 durch eine Dichtlippe angedeutet. Unterhalb von dieser sind mehrere radiale Öffnungen 43 im Schaft 38 geformt für den Eintritt von Material in das Innere des hohlen Schaftes 38.The shaft 38, which is pressed into an axial passage of the housing 24, is seated sealed in the axial passage, e.g. indicated at 41 by a sealing lip. Below this are a plurality of radial openings 43 in the shaft 38 shaped for the entry of material into the interior of the hollow shaft 38.

Zur Betätigung ist erforderlich, den Schaft 38 mehr oder weniger zur Seite zu kippen, wodurch sich das Ventilglied 36 einseitig vom Ventilsitz 38 a abhebt und einen Durchgang zum Inneren des Schaftes 38 freigibt. Ein derartiges Abgabeventil ist im Prinzip bekannt.To actuate it is necessary to tilt the shaft 38 more or less to the side, whereby the valve member 36 stands out on one side from the valve seat 38 a and one Passage to the interior of the shaft 38 releases. Such a delivery valve is in the Principle known.

Das Befüllventil 16 weist ein Gehäuse 44 aus Kunststoffmaterial auf, das mit seinem oberen Ende 46 mit einem Dom 48 eines Ventiltellers 50 durch Pressverformung verbunden ist. Das Ende 46 wirkt mit einer Dichtung 52 zwischen dem oberen Ende des Doms und dem Ventilgehäuse 44 zusammen. Der Ventilteller 50 weist einen im Querschnitt kreisbogenförmigen Rand 54 auf, der eine Dichtung 56 aufnimmt zwecks dichtender Verbindung mit einem eingerollten unteren Rand des Gehäusemantels 12. The filling valve 16 has a housing 44 made of plastic material, which with its upper end 46 with a dome 48 of a valve plate 50 by compression molding connected is. The end 46 acts with a seal 52 between the upper end of the dome and the valve housing 44 together. The valve plate 50 has a Cross-section circular arc-shaped edge 54 which receives a seal 56 for the purpose of a sealing connection with a rolled-in lower edge of the housing shell 12th

Das mit einem axialen Durchgang 58 versehene Ventilgehäuse 44 weist einen inneren verbreiterten Abschnitt 60 auf. Im mittleren Abschnitt des Durchgangs 58 ist eine Druckfeder 62 angeordnet, die gegen das untere Ende eines kolbenförmigen Ventilglieds 64 anliegt, das mit der Dichtung 52 zusammenwirkt. Wird das Ventilglied 64 nach innen gedrückt, wird ein radialer Spalt für den Durchlass eines gasförmigen Mediums freigegeben.The valve housing 44 provided with an axial passage 58 has an inner one widened section 60. In the middle section of the passage 58 is a compression spring 62 arranged against the lower end of a piston-shaped Valve member 64 abuts, which cooperates with the seal 52. Becomes the valve member 64 pressed inwards, a radial gap for the passage of a gaseous Medium released.

Mit dem Abschnitt 60 des Ventilgehäuses 44 ist ein schlauchartiger, spiralförmig gerollter Beutel 68 verbunden (siehe auch Fig. 2), beispielsweise durch Schweißung. Mit Hilfe des Befüllventils 16 kann gasförmiges Medium unter Druck in den Beutel 68 eingefüllt werden. Er versucht sich auszudehnen und wirkt dadurch auf den Kolben 18 und dieser auf das auszutragende Material in der Kammer 20. Der Beutel 68 ist zweckmäßigerweise so geformt, dass er eine gewisse Menge an gasförmigem Treibmedium unter einem relativ hohen Druck aufnimmt, wodurch er sich bei Verschiebung des Kolbens 18 in den Raum 20 hinein ausdehnen kann, bis der Kolben 18 zur Anlage an das Ventilglied 36 gelangt. Auch bei der letzten Bewegung des Kolbens 18 soll der Beutel 68 noch einen ausreichenden Treibdruck auf den Kolben 18 erzeugen.With the section 60 of the valve housing 44 is a hose-like, spiral rolled bag 68 connected (see also Fig. 2), for example by welding. With the help of the filling valve 16, gaseous medium can be put under pressure into the bag 68 can be filled.
