Abstract
Description
Die Erfindung betrifft eine Zweikammerdruckgaspackung, im wesentlichen bestehend aus einem Dosenkörper und einem Balg mit Boden und sich während der Bewegung im Dosenkörper umstülpendem flexiblen Kragen, sowie ein Verfahren zu dessen Herstellung (WO 82/01176).The invention relates to a two-chamber compressed gas pack, essentially consisting of a can body and a bellows with a bottom and a flexible collar that is turned inside the can body during movement, and a method for its production (WO 82/01176).
Eine Zweikammerdruckgaspackung stellt einen Behälter zur Aufnahme und Abgabe von flüssigen und pastösen Produkten unter Druck dar und besteht aus einem steifen, meist metallischen Aussenbehälter, dem Dosenkörper, in dem ein Balg mit steifem Boden und umstülpbarem Kragen derart befestigt ist, dass zwei Kammern gebildet werden, wobei die eine mit dem Entnahmeprodukt und die andere mit einem unter erhöhtem Druck stehenden Treibgas oder eine druckerzeugende Flüssigkeit gefüllt wird. Die Druckentlastung des Treibgases erfolgt über ein produkteseitig angebrachtes Ventil, welches bei Betätigung Produkt aus der Packung fliessen lässt.A two-chamber pressurized gas pack is a container for holding and dispensing liquid and pasty products under pressure and consists of a rigid, mostly metallic outer container, the can body, in which a bellows with a rigid bottom and an invertible collar is attached in such a way that two chambers are formed, one being filled with the removal product and the other being filled with a propellant gas or a pressure-generating liquid under increased pressure. The propellant gas is relieved of pressure via a valve on the product side, which allows product to flow out of the pack when actuated.
Derartige Behälter haben gegenüber den bekannten Sprühdosen den Vorteil, dass das das Produkt austreibende Treibmittel im Behältnis verbleibt und darüber hinaus mit dem Produkt nicht in Berührung kommt. Der letztgenannte Umstand ist insbesondere von grosser Bedeutung, wenn es sich bei dem Produkt um ein Lebensmittel, Kosmetika oder Heilmittel handelt.Such containers have the advantage over the known spray cans that the propellant which expels the product remains in the container and, moreover, does not come into contact with the product. The latter circumstance is of particular importance if the product is a food, cosmetic or medicinal product.
Bei der Zweikammerdruckgaspackung treten jedoch immer wieder Probleme im Bereich der Verbindungsstelle des Balgs mit dem Aussenbehälter oder bei deren Handhabung auf. Der sich während der Bewegung im Dosenkörper umstülpende Kragen wird nach der US-PS 3 415 425 mit seinem Oeffnungsrand in den bodenseitigen Falz des aus Boden, Zylinder und Ventilteller bestehenden dreiteiligen Aussenbehälters integriert, um die notwendige Abdichtung zwischen Produktekammer und Treibmittelkammer zu gewährleisten. In analoger Weise ist nach der US-PS 3 620 420 der Oeffnungsbereich des sich umstülpenden Kragens unter anderem in den Falz des Deckels zur Befestigung des Ventil-Tellers eingeklemmt oder im oberen Teil des Dosenkörpers angeklebt. Zusätzlich wird die Einbringung eines rohrförmigen Stützringes im Bereich des sich umstülpenden Kragens vorgeschlagen, damit dieser kontrolliert geführt wird und sich nicht radial nach innen drückt, was einen Einfluss auf die Ausbringung des Produkts und die Dichtwirkung des Balgs haben könnte.In the case of the two-chamber compressed gas packing, however, problems repeatedly occur in the area of the connection point of the bellows with the outer container or in their handling. According to US Pat. No. 3,415,425, the collar which is turned inside the can body during the movement is integrated with its opening edge into the bottom-side fold of the three-part outer container consisting of bottom, cylinder and valve plate in order to accommodate the to ensure the necessary seal between the product chamber and the propellant chamber. In an analogous manner, according to US Pat. No. 3,620,420, the opening area of the everting collar is, inter alia, clamped in the fold of the cover for fastening the valve plate or glued in the upper part of the can body. In addition, the introduction of a tubular support ring in the region of the everting collar is proposed, so that it is guided in a controlled manner and does not press radially inward, which could have an effect on the output of the product and the sealing effect of the bellows.
Die WO 82/01176 beschreibt eine Zweikammerdruckgaspackung aus einem Dosenkörper, einem Balg im Boden und einem umstülpbaren Kragen. Zur vorgesehenen Handhabung dieser Packung muss der Boden flexibel gestaltet sein. Die Zweikammerdruckgaspackungen nach dem vorgelegten Stand der Technik haben die wesentlichen Nachteile, dass zwingend mehrteilige Dosenkörper erforderlich sind und/oder dass der eingelegte Stützring eine sehr grosse Reibkraft aufbaut, die das Ausbringen des Produkts aufgrund mangelnden Differenzdrucks zwischen den Kammern behindert. Zudem ist der Materialaufwand des Balgs und allenfalls des Stützrings erheblich.WO 82/01176 describes a two-chamber pressurized gas pack consisting of a can body, a bellows in the bottom and an invertible collar. For the intended handling of this pack, the floor must be flexible. The two-chamber pressurized gas packs according to the prior art presented have the major disadvantages that multipart can bodies are absolutely necessary and / or that the inserted support ring builds up a very large frictional force which hinders the application of the product due to a lack of differential pressure between the chambers. In addition, the material expenditure of the bellows and possibly the support ring is considerable.
Die Erfinder haben sich daher die Aufgabe gestellt, eine Zweikammerdruckgaspackung auszubilden, die derartige Nachteile nicht aufweist, und Verfahren zu deren Herstellung zu entwickeln.The inventors have therefore set themselves the task of designing a two-chamber compressed gas pack which does not have such disadvantages and of developing processes for its production.
Der erste Teil der Aufgabe ist durch die in Anspruch 1 angegebenen Merkmale beim Erfindungsgegenstand und durch deren vorteilhafte Weiterbildungen gemäss Anspruch 2 gelöst. Bezüglich des Verfahrens wird erfindungsgemäss die gestellte Aufgabe mit den Merkmalen des Anspruches 3 gelöst.The first part of the object is achieved by the features specified in claim 1 for the subject matter of the invention and by their advantageous developments according to
Die erfindungsgemässe Zweikammerdruckgaspackung zeichnet sich somit dadurch aus, dass nicht allein das Kragenende zur Abdichtung der Kammern verwendet wird, mit der Wirkung, dass der Kragen radial in sich zusammenfallen kann. Darüberhinaus ist zumindest während des Zeitraums, in dem die Druckgaspackung noch grössere Mengen Produkt enthält und somit auch der Treibmitteldruck noch sehr hoch ist, die Dichtfläche gross -- zumindest grösser als bei der Dichtung nach dem vorgelegten Stand der Technik --, sodass geringe Verformungen des zylindrischen Körpers der Druckgaspackung ohne Einfluss auf die Dichtigkeit des sich während der Bewegung umstülpenden Kragens während der Handhabung der Packung bleibt.The two-chamber compressed gas pack according to the invention is thus characterized in that not only the collar end is used to seal the chambers, with the effect that the collar can collapse radially. Furthermore the sealing surface is large, at least during the period in which the compressed gas pack still contains large amounts of product and the propellant pressure is still very high - at least larger than in the case of the seal according to the prior art presented - so that small deformations of the cylindrical Body of the pressurized gas pack without affecting the tightness of the collapsed during movement during handling of the pack remains.
Der Dosenkörper kann in an sich bekannter Weise aus den üblicherweise dazu verwendeten Materialien hergestellt werden. Für die Fertigung des Balgs mit dem sich umstülpenden Kragen kommen sowohl Kunststoffe als auch duktile metallische Werkstoffe und/oder deren Verbunde -- z.B. ein spritzgeformter Kunststoffrohling, dessen Wand durch Thermoformung ausgedünnt ist, thermogeformter Kunststoffverbund, tiefgezogener und/oder streckgezogener Aluminium-Kunststoffverbund oder insbesondere eine fliessgepresste, weichgeglühte und innenlackierte Hülse mit gegebenenfalls ein Nebenformelement aufweisendem Boden, wobei bei den letzten beiden Möglichkeiten am offenen, dem Produkt zugewandten Ende eine nach aussen gelegte Doppelung des Kragens vorgesehen sein kann -- zur Anwendung.The can body can be produced in a manner known per se from the materials usually used for this purpose. For the production of the bellows with the everting collar, both plastics and ductile metallic materials and / or their composites are used - e.g. an injection-molded plastic blank, the wall of which is thinned out by thermoforming, thermoformed plastic composite, deep-drawn and / or stretch-drawn aluminum-plastic composite, or in particular an extruded, soft-annealed and internally varnished sleeve with a base that may have a secondary molding element, with the last two options using the open, product-facing element At the end, an outward doubling of the collar can be provided - for use.

Die erfindungsgemässe Zweikammerdruckgaspackung besteht aus einem Dosenkörper 10 mit ein Ventil 5 enthaltendem Boden 6 und einem durch Rollrand 7 befestigten, ein Produktentnahmeventil 8 enhaltenden Ventilteller 9. Im Dosenkörper 10 ist ein Balg 20 mit formfestem Boden 23, dem ein ringförmiges oder sonstwie gestaltetes Nebenformelement 2 angeformt sein kann, und Kragen 21 enthalten. Der aus flexiblem Material bestehende Kragen 21 ist mit seiner gesamten Mantelfläche an der Innenwand 11 des Dosenkörpers 10 befestigt. Die Befestigung kann z.B. durch Reib- und/oder Formschluss oder mit Hilfe eines Klebers 30 erfolgen. Im Innenraum des Dosenkörpers 10 entstehen dadurch zwei Kammern, nämlich eine zwischen Boden 23 des Balgs 20 und Boden 6 des Dosenkörpers 10 liegende, das Treibgas enthaltende Kammer 12 und eine zwischen Boden 6 des Balgs 20 und Ventilteller 9 des Dosenkörpers 10 liegende, das Entnahmeprodukt enthaltende Kammer 22. Die Befestigung des Kragens 21 an die Innenwand 11 des Dosenkörpers 10 ist derart, dass bei Betätigung des Ventils 8 das mit Ueberdruck in die Kammer 12 eingebrachte Treibgas durch Druckentlastung den Boden 23 des Balgs 20 in Richtung Ventil 8 drücken kann, wobei sich die Verbindung zwischen Kragen 21 und Innenwand 11 soweit abschält wie die Umstülpung des Kragens 21 (im Bereich der Vorformung 24) von Boden 23 und Kragen 21 erfolgt. Zur Verhinderung von Faltenbildungen in diesem Bereich kann zusätzlich ein ringförmiger Faltenhalter 26 in den Balg 20 eingeführt werden.The two-chamber compressed gas pack according to the invention consists of a
Der Befestigung des Balgs 20 an die Innenwand des Dosenkörpers kommt bei der erfindungsgemässen Zweikammerdruckgaspackung grösste Bedeutung zu. Fig. 2 zeigt eine Möglichkeit der Befestigung. Der Balg 20 mit einem gegenüber dem Innendurchmesser des Dosenkörpers 10 geringfügig geringeren Aussendurchmesser wird in den Dosenkörper 10 eingeschoben und anschliessend der Dosenkörper 10 zumindest im Mantelbereich des Kragens 21 durch einen Einziehring 60 mit konischem Einlauf 61 im Durchmesser reduziert und dadurch auf den Balg 10 aufgeschrumpft. Dieses besonders geeignete Verfahren findet bevorzugt Anwendung, wenn sowohl der Dosenkörper 10 als auch der Balg 20 aus Metall, insbesondere aus einem Aluminiumwerkstoff, bestehen.The attachment of the
Eine weitere Möglichkeit besteht darin, dass der Kragen 21 mit der Innenwand 11 des Dosenkörpers 10 dadurch verbunden wird, dass durch Druckbeaufschlagung über entsprechende Zuführungen 47 auf die inseits dem Kragen 21 zugewandte Wandung 46 eines in den Dosenkörper 10 vor Montage des Ventiltellers 9 eingebrachten Expansionsdorns 45 der Kragen 21 auf die Innenwand 11 des Dosenkörpers 10 gepresst wird.A further possibility is that the
Bei einer noch weiteren Möglichkeit zur Herstellung der erfindungsgemässen Zweikammerdruckgaspackung werden der Kragen 21 und die Innenwand 11 des Dosenkörpers 10 durch Aufstecken des Balgs 20 auf einen im Bereich des Kragens 21 einen gegenüber dem Innendurchmesser des Balgs geringfügig geringeren Durchmesser aufweisenden Dorn 40, - bei Verwendung eines Kontaktklebers befindet sich dieser auf Raumtemperatur, bei Verwendung eines Hotmelts wird er vorgewärmt -, Einführen dieser Teileanordnung vor Montage des Ventiltellers 9 in den Dosenkörper 10 und anschliessendes Abrollen einer auf einer Welle 51 drehbar angeordneten Walze 50 auf der Aussenwand 13 des Dosenkörpers 10 im Umbereich des Kragens 21 miteinander verbunden.In a still further possibility of producing the two-chamber compressed gas pack according to the invention, the
