Abstract

Cylindrical container has a piston dividing the interior into two parts, a material delivery valve at the upper end and a valve at the lower end for supplying pressurized gas to an expandable tubular drive member. 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 packages of different design and for different materials are widely known. Thus, the most diverse flowable media in cosmetics, cleaning agents, food, in the construction industry and the like are packaged in dispensing packages and dispensed using appropriate dispensing and metering devices. Aerosol dispensers are particularly widespread, in which a propellant gas is added under pressure to a liquid medium. The discharge of the medium via a corresponding dispensing valve and possibly a so-called spray head. It is also known to house the medium to be discharged in a bag which is connected to the dispensing valve and which is accommodated in a container, which in turn is filled with a propellant. The propellant presses on all sides of the bag and in this way presses the medium out of the bag when the dispensing valve is actuated. Such a package is used to prevent the gaseous propellant from coming into contact with the medium to be discharged. In addition, pasty media can be discharged in this way with the aid of a gaseous propellant. It is also known to reverse the arrangement in the package described last and the propellant in a To fill bag and the medium to be discharged in the container space surrounding the bag.

FR 1 046 624 zeigt eine Spenderpackung zum Austragen eines pastösen Mediums, das in einem zieharmonikaförmig gefalteten Behälter vorgesehen ist. Die Einlaßöffnung für das Treibgas in dem Behälter wird durch eine Schraube verschlossen.FR 1 046 624 shows a dispensing package for dispensing a pasty medium, which is provided in a concertina-folded container. The inlet opening for the propellant gas in the container is closed by a screw.

Aus DE 3 721 099 ist eine Abgabepackung mit einem Kolbenelement bekannt, das über einen mit Gas befüllten zieharmonikaförmigen Beutel angetrieben wird. Das Antriebsgas wird über ein Einflußrohr eingefüllt, das nach dem Befüllen mit einer Kappe verschlossen wird.From DE 3 721 099 a dispensing pack with a piston element is known, which is driven by a gas-filled accordion-shaped bag. The drive gas is introduced via a flow tube, which is closed after filling with a cap.

Aus JP 57194970 ist eine Abgabepackung mit einem Kolbenelement bekannt, das über einen zieharmonikaförmig gefalteten Beutel angetrieben wird. Der befüllte Beutel wird an der Unterseite verschlossen.From JP 57194970 a dispensing pack with a piston element is known, which is driven by a concertina folded bag. The filled bag is closed at the bottom.

Der Erfindung liegt die Aufgabe zugrunde, eine Spenderpackung für viskoses oder pastöses Material zu schaffen, bei der mit einfachen Mitteln ein Befüllen mit einem gasförmigen Treibmittel erfolgen kann.The invention has for its object to provide a dispenser package for viscous or pasty material in which can be done with simple means filling with a gaseous propellant.

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 durch einen in einem zylindrischen Behälter gleitend bewegbaren Kolben den zylindrischen Innenraum 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 package according to the invention divided by a slidably movable in a cylindrical container piston, the cylindrical interior in an upper and a lower space. The upper space serves to receive the material to be discharged, and the lower space receives a tubular or bag-shaped driving member, which rests against the piston and filled with propellant gas. The filling takes place via a filling valve at the lower end of the container, with the housing, the drive member is connected. At the upper end of the container, a conventional dispensing valve is provided, which may be formed as a tilting valve according to one 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 ggfs. 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 may already be mounted prior to filling the container with the material to be dispensed. It is therefore not necessary to enter the material under pressure if necessary, via the filling valve in the container. After filling with the material to be dispensed, the piston is inserted and mounted the drive member with the filling valve. The latter is effectively connected in a manner known per se sealingly with the container. Now propellant gas is introduced into the drive member under pressure via the filling valve to a predetermined pressure, the amount charged and the pressure sufficient to effectively drive the piston to the upper end of the container. It is understood that the filling valve is arranged so that it does not project beyond the lower end of the container, thus the container can be placed upright on a base. In addition, a cap, for example made of plastic, can be placed on the lower end of the container in order to protect the filling valve and to prevent accidental operation. Furthermore, this makes 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 may be formed of an optionally coated plastic film, which is spirally rolled, folded or arranged in the form of a concertina in the lower space and is suitably connected to the housing of the filling valve, 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 may be formed of sheet metal or plastic. When sheet metal material is used, a so-called valve plate is usually provided for both the dispensing valve and the filling valve, which is connected to the edge of the container by press-forming. If, however, a plastic container provided, for example, the filling valve can be suitably connected or welded to the container edge. For the dispensing valve can also be provided to press the housing of the filling valve in an opening of the container. Special molding processes are not required. The valve housing may be made of elastic material to be pressed into the container opening. Subsequently, a dispensing stem with valve member can be pressed 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 receive viscous or pasty material, e.g. Sealing materials that must not come into contact with air before discharge, otherwise they harden and / or react chemically. These include PU foam or PU adhesive for construction, but also cosmetics, food or the like.

Die Erfindung wird nachfolgend anhand eines in Zeichnungen dargestellten Ausführungsbeispiels näher erläutert.The invention will be explained in more detail with reference to an embodiment shown in the drawings.

Fig. 1 zeigt einen Schnitt durch eine Packung nach der Erfindung.Fig. 1 shows a section through a package 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, whose jacket 12 is made of plastic or sheet metal. At the upper end of the container 10, a dispensing valve 14 is provided and at the lower end of a filling valve 16. Within the container shell 12 designed as a plastic disc piston 18 is arranged. It is slidably and sealingly movable in the container and divides the interior of the container into an upper space 20 for receiving a material to be discharged and a lower space 22. Since the container 10 is relatively long, a middle part is not shown for illustrative reasons.

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. It is sleeve-shaped with a lower radial flange 26 and an annular groove 28 above the flange 26. The edge of an upper opening of the container 10 is seated in the groove 28. The opening has a circular arc in cross-section, upwardly bent edge 32. The valve housing 24th is pressed into the opening of the container 10, wherein the edge 32 snaps into the groove 28. As a result, the housing 24 is held on the container 10. A plate-shaped valve member 36 cooperates sealingly with a lower valve seat 38a of the housing 24. With the valve member 36, a hollow shaft 38 is integrally connected, which has a radial flange 40 which cooperates with the upper sleeve-shaped end of the housing 24. In the position shown, a certain tension between the flange 40 and the valve member 36 is exerted by the housing 24. In this way there is a sufficient seal on the valve seat 38a, which is reinforced by the pressure prevailing in the space 20.

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 press-fit into an axial passage of the housing 24, is sealed in the axial passageway, e.g. indicated at 41 by a sealing lip. Below this, a plurality of radial openings 43 are formed in the shaft 38 for 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 lifts off from the valve seat 38 a on one side and a passage to the interior of the shaft 38 releases. Such a dispensing valve is known in principle.

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 is connected at its upper end 46 with a dome 48 of a valve disk 50 by compression deformation. The end 46 cooperates with a seal 52 between the top of the dome and the valve housing 44. The valve disk 50 has a cross-sectionally circular edge 54, which receives a seal 56 for the purpose of sealing connection with a rolled-up lower edge of the housing jacket 12.

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 widened portion 60. In the middle portion of the passage 58, a compression spring 62 is arranged, which abuts against the lower end of a piston-shaped valve member 64, which cooperates with the seal 52. When the valve member 64 is pushed inward, a radial gap for the passage of a gaseous medium is 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.To the portion 60 of the valve housing 44, a tubular, spirally rolled bag 68 is connected (see also Fig. 2), for example by welding. With the help of the filling valve 16 gaseous medium can be filled under pressure into the bag 68. He tries to expand and thereby acts on the piston 18 and this acts on the material to be discharged in the chamber 20. The bag 68 is suitably shaped so that it receives a certain amount of gaseous propellant medium under a relatively high pressure, whereby it moves of the piston 18 can expand into the space 20 until the piston 18 comes to bear against the valve member 36. Even with the last movement of the piston 18, the bag 68 should still generate sufficient driving pressure on the piston 18.

Auch das Befüllventil 16 ist in seinem grundsätzlichen Aufbau an sich bekannt. Es ist versenkt am Behälter 10 angeordnet, so dass der Behälter 10 aufrecht auf einer Unterlage abgestellt werden kann. Eine Kappe 70 ist auf den Rand 54 des Tellers 50 geclipst und verdeckt so das Befüllventil 16. Außerdem ermöglicht er ein sicheres Aufstellen der Packung 10 auf einer Unterlage.Also, the filling valve 16 is known per se in its basic structure. It is sunk on the container 10, so that the container 10 upright on a Pad can be turned off. A cap 70 is clipped onto the edge 54 of the plate 50 and so covers the filling valve 16. In addition, it allows a secure placement of the pack 10 on a base.
