Blistern finden in zahlreichen Gebieten breite Anwendung, in denen mehrere oder unterschiedliche Stoffe in einer gemeinsamen Verpackung aufbewahrt werden sollen, beispielsweise bei Medikamenten.Multi-compartment or blister packs are widely used in many areas in which several or different materials are to be stored in a common package, for example, medicines.

Die WO 00/09414 offenbart einen Mehrkammerbehälter mit zwei Kammern bzw. Näpfen, die mittels eines Steges voneinander getrennt und durch eine Deckfolie verschlossen sind. Dabei ist die Aufsiegelung der Deckfolie derart ausgelegt, dass diese im Bereich des Verbindungssteges leicht durchbrochen werden kann, um den vorzugsweise flüssigen Inhalt der beiden Kammern miteinander zu mischen.The WO 00/09414 discloses a multi-chamber container with two chambers or wells, which are separated by a ridge and closed by a cover sheet. The Aufsiegelung the cover sheet is designed such that it can be easily broken in the region of the connecting web to mix the preferably liquid content of the two chambers with each other.

Derartige Mehrkammerverpackungen kommen prinzipiell für beliebige Anwendungen in Betracht, bei denen zwei oder mehr Komponenten gelagert und kurz vor dem Gebrauch gemischt werden müssen. Allerdings haben sich die bekannten Mehrkammerverpackungen für einige Anwendungen als nicht geeignet erwiesen. So sind beispielsweise die in der WO 00/09414 offenbarten Mehrkammerbehälter mit Kunststoffnäpfen nicht für Stoffe geeignet, die gasdicht verpackt werden müssen, da diese sonst einer Qualitätsverschlechterung unterliegen, wie beispielsweise Farbcremes von 2-Komponenten-Haarfärbemitteln.Such multi-chamber packages are in principle for any applications into consideration, in which two or more components must be stored and mixed just before use. However, the known multi-chamber packaging for some applications have proved to be unsuitable. For example, those in the WO 00/09414 disclosed multi-chamber container with plastic cups not suitable for substances that are packaged gas-tight otherwise they are subject to quality deterioration, such as color creams of 2-component hair dye.

Ferner offenbart die WO 02/064444 A2 eine Mehrkomponentenverpackung, bei der die Kammern bzw. Näpfe der Verpackung aus Aluminiumfolie gebildet sind, so dass die verpackten Stoffe weitgehend gasdicht verpackt werden. Eine derartige Verpackung eignet sich jedoch nicht für oxidierende Stoffe, wie beispielsweise Peroxid, die in einer gasdichten Verpackung aufgrund von Entgasungsvorgängen zu starken Verformungen und ggf. einer Beschädigung der Verpackung führen können.Further, the WO 02/064444 A2 a multi-component packaging, in which the chambers or wells of the packaging are formed from aluminum foil, so that the packaged substances are largely sealed gas-tight. However, such a package is not suitable for oxidizing substances, such as peroxide, which can lead to severe deformations and possibly damage to the packaging in a gas-tight packaging due to degassing operations.

Weiterhin offenbart die WO 02/074657 A1 einen Mehrkammerbehälter, der aus einem Verbundmaterial hergestellt ist, das eine gasundurchlässige Kunststoffschicht aufweist. Dabei kann die gasundurchlässige Schicht derart angeordnet sein, dass nur ein Teil der Kammern gasdicht verschlossen werden. Zur Herstellung des Mehrkammerbehälters muss das Verbundmaterial in jedem Einzelfall entsprechend der Geometrie und Anordnung der Kammern vorbereitet werden.Furthermore, the disclosure WO 02/074657 A1 a multi-chamber container made of a composite material having a gas-impermeable plastic layer. In this case, the gas-impermeable layer may be arranged such that only a portion of the chambers are sealed gas-tight. To produce the multi-chamber container, the composite material must be prepared in each individual case according to the geometry and arrangement of the chambers.

Ferner offenbaren die JP 07155361 A , EP-A-0 639 364 und JP 11227843 A verschiedene Verpackungen mit mehreren Speicherkammern.Furthermore, the JP 07155361 A . EP-A-0 639 364 and JP 11227843 A different packaging with several storage chambers.

Darstellung der ErfindungPresentation of the invention

Es ist daher Aufgabe der vorliegenden Erfindung, ein einfaches Verfahren, zur Herstellung einer verbesserten Verpackung mit mindestens zwei Speicherkammern, bereitzustellen.It is therefore an object of the present invention to provide a simple method for producing an improved packaging with at least two storage chambers.

Diese Aufgabe wird gemäß der vorliegenden Erfindung durch ein Verfahren nach Anspruch 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved according to the present invention by a method according to claim 1. Advantageous developments of the invention are specified in the dependent claims.

Der Erfindung liegt der Gedanke zugrunde, eine Verpackung zu schaffen, bei der die Herstellung stets mit demselben Ausgangsmaterial erfolgen kann, ohne dass in jedem Einzelfall eine Vorkonfektionierung entsprechend der gewünschten Permeabilitätseigenschaften der Kammern erforderlich ist. Zu diesem Zweck ist erfindungsgemäß vorgesehen, dass
die Blisterabschnitte aus einem Verbundmaterial mit mindestens zwei Schichten gebildet sind, wobei zumindest eine der Schichten im wesentlichen gasundurchlässig, insbesondere sauerstoffundurchlässig ist und eine geringere Bruchdehnung bei Zugbeanspruchung besitzt als die übrigen Schichten.The invention is based on the idea to provide a packaging in which the production always with the same Starting material can be done without in each case a prefabrication according to the desired permeability properties of the chambers is required. For this purpose, the invention provides that
the blister sections are formed from a composite material having at least two layers, wherein at least one of the layers is substantially gas-impermeable, in particular impermeable to oxygen, and has a lower tensile elongation at tensile stress than the remaining layers.

Hierdurch können die Blisterabschnitte derart ausgebildet werden, dass die mindestens eine, im Wesentlichen gasundurchlässige Schicht in einem oder mehreren Blisterabschnitten durchgängig vorhanden ist, sodass sich eine im Wesentlichen gasdichte Speicherkammer ergibt, während die mindestens eine, im Wesentlichen gasundurchlässige Schicht in den übrigen Kammern zumindest abschnittsweise unterbrochen sein kann, sodass sich in diesen Kammern eine Gasdurchlässigkeit mit einem gewünschten Ausmaß einstellt. Auf diese Weise lassen sich verschiedenartigste Speicherkammern in einer einzigen Verpackung zusammenfassen, wobei die Speicherkammern jeweils eine gewünschte Gasdurchlässigkeit besitzen und somit Lagerbedingungen bereitstellen, wie sie von bestimmten Stoffen jeweils gefordert werden. Insbesondere lässt sich eine derartige Verpackung problemlos ausgehend von einem einzigen Verbundmaterial herstellen, das in keiner Weise vorkonfektioniert werden muss. Hierdurch wird die Herstellung der erfindungsgemäßen Verpackung gegenüber dem Stand der Technik erheblich vereinfacht.As a result, the blister sections can be formed in such a way that the at least one essentially gas-impermeable layer is present in one or more blister sections, so that a substantially gas-tight storage chamber results, while the at least one, essentially gas-impermeable layer in the remaining chambers at least in sections may be interrupted, so that sets in these chambers a gas permeability to a desired extent. In this way, a variety of storage chambers can be summarized in a single package, the storage chambers each have a desired gas permeability and thus provide storage conditions, as required by certain substances. In particular, such a package can be easily prepared from a single composite material which need not be pre-assembled in any way. As a result, the production of the packaging according to the invention over the prior art is considerably simplified.

In der erfindungsgemäßen Verpackung können bei einfacher Herstellung beispielsweise 2-Komponenten-Haarfärbemittel, 2-Komponenten-Klebstoffe oder dergleichen bis zum Gebrauch in einer einzigen Verpackung gelagert und auch in dieser gemischt werden, ohne dass eine der beiden Komponenten seine Eigenschaften während der Lagerung wesentlich verändert oder die Verpackung beschädigt.In the packaging according to the invention, for example, 2-component hair dyes, 2-component adhesives or the like can be stored in a single package until use and also mixed in this, without either of its two components Properties during storage changed significantly or damaged the packaging.

Gemäß einer Weiterbildung der vorliegenden Erfindung beträgt die Bruchdehnung der mindestens einen, im wesentlichen gasundurchlässigen Schicht (14) höchstens 50 %, bevorzugt höchstens 25 %, besonders bevorzugt höchstens 10 % derjenigen der übrigen Schichten (12, 16). Hierdurch lässt sich in vorteilhafter Weise der Herstellungsvorgang der erfindungsgemäßen Verpackung weiter vereinfachen, indem die gewünschte Differenz der Gasdurchlässigkeit zwischen den Kammern bereits bei geringen Verformungsgraden erzielen lässt.According to a development of the present invention, the elongation at break of the at least one essentially gas-impermeable layer (14) is at most 50%, preferably at most 25%, particularly preferably at most 10%, of that of the remaining layers (12, 16). As a result, the manufacturing process of the packaging according to the invention can be further simplified in an advantageous manner by the desired difference in gas permeability between the chambers can be achieved even at low deformation levels.

Dabei ist es erfindungsgemäß besonders bevorzugt, dass die Blisterabschnitte aus einem Metall-Kunststoff-Verbundmaterial, insbesondere einem Aluminium-Kunststoff-Verbundmaterial gebildet sind, wobei die mindestens eine, im wesentlichen gasundurchlässige Schicht (14) bevorzugt Metall aufweist. In einem derartigen Verbundmaterial sorgt mindestens eine Metallschicht für die gewünschte Gasundurchlässigkeit, während der Kunststoffanteil je nach Aufbau, Verformungsgrad etc. einen gewissen Gasaustausch entsprechend den Anforderungen ermöglicht. Ferner lassen sich Metall-Kunststoff-Verbundmaterialien leicht und kostengünstig herstellen und problemlos in die gewünschte Form bringen.It is particularly preferred according to the invention that the blister sections are formed of a metal-plastic composite material, in particular an aluminum-plastic composite material, wherein the at least one, substantially gas-impermeable layer (14) preferably comprises metal. In such a composite material provides at least one metal layer for the desired gas impermeability, while the plastic content, depending on the structure, degree of deformation, etc. allows a certain gas exchange according to the requirements. Furthermore, metal-plastic composites can be easily and inexpensively manufactured and easily bring in the desired shape.

Das Ausformen der Blisterabschnitte erfolgt gemäß einer Weiterbildung der vorliegenden Erfindung zumindest teilweise durch Verformung, insbesondere durch Tiefziehen. Dabei ergibt sich eine radikal vereinfachte Herstellung der Blisterabschnitte mit unterschiedlicher Gasdurchlässigkeit, wenn der mindestens eine Blisterabschnitt mit der größeren Gasdurchlässigkeit einen höheren Verformungsgrad besitzt als die übrigen Blisterabschnitte. Die Erfinder haben nämlich überraschenderweise festgestellt, dass sich über die Wahl des Verformungsgrades die Gasdurchlässigkeit der einzelnen Blisterabschnitte auf einfache und zuverlässige Weise steuern lässt. Dies gilt insbesondere bei Metall-Kunststoff-Verbundmaterialien, bei denen bei geringen Verformungsgraden die mindestens eine Metallschicht ungerissen bleibt, sodass die entsprechende Blisterkammer im Wesentlichen gasundurchlässig ist, während die mindestens eine Metallschicht bei höheren Verformungsgraden zunehmend Mikrorisse bzw. auch diskrete Risse oder Spalte aufweist, sodass die Gasdurchlässigkeit mit zunehmendem Verformungsgrad ebenfalls zunimmt. Die vorliegende Erfindung ist jedoch nicht auf die Verwendung von Metall-Kunststoff-Verbundmaterialien beschränkt, sondern ist auch auf andere Materialien anwendbar, wobei allgemein Verbundmaterialien bevorzugt sind.The blister sections are formed at least partially by deformation, in particular by deep drawing, according to a development of the present invention. This results in a radically simplified production of the blister sections with different gas permeability, if the at least one blister section with the larger gas permeability has a higher degree of deformation than the other blister sections. The inventors have surprisingly found that the choice of the degree of deformation, the gas permeability of the individual Blister sections in a simple and reliable way can be controlled. This applies in particular in the case of metal-plastic composite materials in which the at least one metal layer remains non-cracked at low degrees of deformation, so that the corresponding blister chamber is essentially impermeable to gas, while the at least one metal layer increasingly exhibits microcracks or even discrete cracks or gaps at higher degrees of deformation, so that the gas permeability also increases with increasing degree of deformation. However, the present invention is not limited to the use of metal-plastic composite materials, but is also applicable to other materials, with composite materials being generally preferred.

Gemäß einer Weiterbildung der vorliegenden Erfindung umschließt der mindestens eine Blisterabschnitt mit der größeren Gasdurchlässigkeit ein größeres Volumen und/oder besitzt eine größere Höhe als die übrigen Blisterabschnitte. Durch diese Maßnahme kann ohne direkte oder indirekte Messung des Verformungsgrades sichergestellt werden, dass der mindestens eine Blisterabschnitt tatsächlich eine größere Gasdurchlässigkeit besitzt, wodurch Steuerung und Kontrolle bei der Herstellung und Befüllung der Verpackung vereinfacht werden.According to a development of the present invention, the at least one blister section with the greater gas permeability encloses a larger volume and / or has a greater height than the remaining blister sections. By this measure it can be ensured, without direct or indirect measurement of the degree of deformation, that the at least one blister section actually has a greater gas permeability, whereby control and control in the production and filling of the packaging are simplified.

Im Hinblick auf ein einfaches und sicheres Mischen der verschiedenen in den Blisterabschnitten enthaltenen Komponenten ist gemäß einer Weiterbildung der vorliegenden Erfindung vorgesehen, dass die Deckabschnitte mit den Blisterabschnitten derart verbunden sind, dass die Siegelfestigkeit im Bereich zwischen benachbarten Blisterabschnitten zumindest abschnittsweise geringer ist als an freien Rändern der Blisterabschnitte. Hierdurch wird sichergestellt, dass das Mischen der Komponenten durch einfaches Drücken der Blisterabschnitte eingeleitet und durchgeführt werden kann, da hierdurch die Siegelnaht im Bereich zwischen benachbarten Blisterabschnitten gelöst wird, während die umlaufende Siegelnaht intakt bleibt und dafür sorgt, dass die Komponenten nicht vorzeitig aus der Verpackung austreten.With regard to a simple and secure mixing of the various components contained in the blister sections is provided according to a development of the present invention that the cover sections are connected to the blister sections such that the seal strength in the area between adjacent Blisterabschnitten is at least partially smaller than at free edges the blister sections. This ensures that the mixing of the components can be initiated and carried out by simply pressing the blister sections, since this causes the sealed seam to be released in the area between adjacent blister sections, while the circumferential seal remains intact and ensures that the components do not escape from the package prematurely.

Die erfindungsgemäße Verpackung ist selbstverständlich für beliebige Stoffe und Stoffkombinationen geeignet. Es hat sich jedoch gezeigt, dass die erfindungsgemäße Verpackung besonders zur Aufnahme von Komponenten von Haarpflege und/oder Haarkosmetikmitteln geeignet ist, wobei die mindestens eine Speicherkammer mit der größeren Gasdurchlässigkeit bevorzugt oxidierende Komponenten wie insbesondere Peroxid enthält. Die Komponenten derartiger Mittel wurden bisher üblicherweise in getrennten Verpackungen mit einem zusätzlichen Mischgefäß ausgeliefert, was ein umständliche Handhabung und ein hohes Maß an Verpackungsmaterial mit sich brachte. Demgegenüber ist es mit der erfindungsgemäßen Verpackung möglich, die Komponenten in einer einzigen Verpackung zusammenzufassen, in der kurz vor dem Gebrauch auch noch das Mischen durchgeführt werden kann, sodass die erfindungsgemäße Verpackung dem Benutzer ausgezeichnete Gebrauchseigenschaften bietet. Diese Vorteile sind insbesondere auch für Endverbraucher von Bedeutung, die in der Handhabung chemischer Substanzen, die teilweise aggressive Wirkungen besitzen, keine oder nur geringe Erfahrung besitzen. Daher wird durch die erfindungsgemäße Verpackung auch die Anwendungssicherheit erhöht.The packaging according to the invention is of course suitable for any substances and combinations of substances. However, it has been found that the packaging according to the invention is particularly suitable for receiving components of hair care and / or hair cosmetics, wherein the at least one storage chamber with the greater gas permeability preferably contains oxidizing components such as in particular peroxide. The components of such agents have traditionally been delivered in separate packages with an additional mixing vessel, resulting in cumbersome handling and a high level of packaging material. In contrast, with the packaging according to the invention it is possible to combine the components in a single package in which mixing can be carried out shortly before use so that the packaging according to the invention offers the user excellent performance characteristics. These advantages are particularly important for end users who have little or no experience in the handling of chemical substances that sometimes have aggressive effects. Therefore, the application security is increased by the packaging according to the invention.

Ausführliche Beschreibung bevorzugter AusführungsformenDetailed description of preferred embodiments

Bevorzugte Ausführungen der vorliegenden Erfindung werden nachfolgend ausführlich unter Bezugnahme auf Fig. 1 beschrieben, die schematisch eine Schnittansicht einer bevorzugten Ausführungsform einer erfindungsgemäßen Verpackung 1 zeigt.Preferred embodiments of the present invention will be described below in detail with reference to FIG Fig. 1 which schematically shows a sectional view of a preferred embodiment of a package 1 according to the invention.

Die Verpackung 1 umfasst in der vorliegenden Ausführungsform zwei Speicherkammern 2, 4 zur Aufnahme zu verpackender Stoffe. Es ist jedoch selbstverständlich, dass die erfindungsgemäße Verpackung 1 eine beliebige Anzahl von Speicherkammern aufweisen kann. Bei den zu verpackenden Stoffen kann es sich prinzipiell um beliebige, flüssige, feste oder auch gasförmige Stoffe handeln, wobei die Verpackung bevorzugt für Stoffe zum Einsatz kommt, die miteinander gemischt werden sollen und/oder ein unterschiedliches Entgasungsverhalten besitzen.The packaging 1 in the present embodiment comprises two storage chambers 2, 4 for receiving substances to be packaged. However, it goes without saying that the packaging 1 according to the invention can have any desired number of storage chambers. The substances to be packaged can in principle be any liquid, solid or also gaseous substances, the packaging preferably being used for substances which are to be mixed with one another and / or have a different degassing behavior.

Die Speicherkammern 2, 4 sind jeweils durch einen Blisterabschnitt 2', 4' und einen Deckabschnitt 2'', 4'' begrenzt. Dabei ist es erfindungsgemäß bevorzugt, dass die Deckabschnitte, die beispielsweise durch eine oder mehrere Folien gebildet sein können, mit den Blisterabschnitten durch Siegelnähte S, R verbunden sind, wobei die Siegelfestigkeit der Nähte S zwischen benachbarten Blisterabschnitten geringer ist als diejenige der Siegelnähte R an freien Rändern der Blisterabschnitte. Bei dem Material der Deckabschnitte kann es sich beispielsweise um eine Kunststoff- oder Aluminiumfolie handeln, wobei auch dasselbe Material wie bei den Blisterabschnitten zum Einsatz kommen kann.The storage chambers 2, 4 are each bounded by a blister section 2 ', 4' and a cover section 2 '', 4 ''. It is inventively preferred that the cover sections, which may be formed for example by one or more films are connected to the blister sections through sealing seams S, R, wherein the seal strength of the seams S between adjacent Blisterabschnitten is less than that of the sealed seams R to free Edges of the blister sections. The material of the cover sections may, for example, be a plastic or aluminum foil, whereby the same material as in the blister sections may also be used.

Die Blisterabschnitte sind aus einem Verbundmaterial 10 gebildet, das in der vorliegenden Ausführungsform drei Schichten 12, 14, 16 aufweist, wobei es sich bei den beiden äußeren Schichten 12, 16 um ein Kunststoffmaterial handelt, während die mittlere Schicht 14 in der vorliegenden Ausführungsform durch einen Aluminiumfilm gebildet ist. Das Verbundmaterial kann jedoch auch einen andersartigen Schichtaufbau besitzen, wobei allgemein Metall-Kunststoff-Verbundmaterialien bevorzugt sind. Wesentlich ist ferner, dass zumindest eine Schicht des Verbundmaterials im Wesentlichen gasundurchlässig ist, wie beispielsweise die Aluminiumfolie, und ferner eine geringer Bruchdehnung bei Zugbeanspruchung besitzt als die übrigen Schichten. Die Bruchdehnung kann dabei beispielsweise nach DIN EN ISO 527 bestimmt werden.The blister sections are formed from a composite material 10 which, in the present embodiment, has three layers 12, 14, 16, the two outer layers 12, 16 being a plastic material, while the middle layer 14, in the present embodiment, is a Aluminum film is formed. However, the composite material can also be a different type Have layer structure, with metal-plastic composite materials are generally preferred. It is also essential that at least one layer of the composite material is substantially gas-impermeable, such as the aluminum foil, and further has a low elongation at break in tensile stress than the other layers. The elongation at break can be determined, for example, according to DIN EN ISO 527.

Wie in Fig. 1 zu erkennen, ist bei dem Blisterabschnitt 2' die mittlere (Aluminium-)Schicht 14 durchgängig vorhanden, während bei dem Blisterabschnitt 4' die mittlere Schicht 14 Unterbrechungen U aufweist. Dementsprechend ist der Blisterabschnitt 2' bzw. die Speicherkammer 2 im Wesentlichen gasdicht ausgebildet, während der Blisterabschnitt 4' bzw. die Speicherkammer 4 eine bestimmte Gasdurchlässigkeit besitzt, die von der Gasdurchlässigkeit des (Kunststoff-)Materials der Schichten 12, 16 abhängt. Die Gasdurchlässigkeit der Blisterabschnitte 2', 4' kann dabei insbesondere nach DIN 53380 oder vergleichbaren Messverfahren bestimmt werden.As in Fig. 1 can be seen in the blister section 2 ', the middle (aluminum) layer 14 is continuously present, while in the blister section 4', the middle layer 14 has interruptions U. Accordingly, the blister section 2 'or the storage chamber 2 is formed essentially gas-tight, while the blister section 4' or the storage chamber 4 has a certain gas permeability, which depends on the gas permeability of the (plastic) material of the layers 12, 16. The gas permeability of the blister sections 2 ', 4' can be determined in particular according to DIN 53380 or comparable measuring methods.

In Fig. 1 ist ferner zu erkennen, dass der Blisterabschnitt 4' mit der größeren Gasdurchlässigkeit in der vorliegenden Ausführungsform ein größeres Volumen V umschließt und auch eine größere Höhe h besitzt als der benachbarte Blisterabschnitt 2'. Hierdurch lassen sich die verschiedenen Blisterabschnitte mit den unterschiedlichen Eigenschaften nicht nur leicht unterscheiden, sondern der Volumen- bzw. Höhenunterschied ergibt sich oft aus dem erfindungsgemäßen Herstellungsverfahren, das nachfolgend ausführlicher beschrieben wird.In Fig. 1 It can also be seen that the blister section 4 'with the greater gas permeability in the present embodiment encloses a larger volume V and also has a greater height h than the adjacent blister section 2'. As a result, not only can the various blister sections with the different properties be slightly different, but the difference in volume or height often results from the production method according to the invention, which will be described in more detail below.

Bei der Herstellung der erfindungsgemäßen Verpackung 1 wird zunächst von dem Metall-Kunststoff-Verbundmaterial 10 mit den oben beschriebenen Eigenschaften ausgegangen. In diesem Material werden durch Verformung, insbesondere durch Tiefziehen, Warmverformen oder ein ähnliches Verformungsverfahren, die Blisterabschnitte 2', 4' ausgebildet, wobei der Verformungsgrad des Blisterabschnitts 4' größer eingestellt wird als derjenige des Blisterabschnitts 2'. Dabei kann der Verformungsgrad mit einfachen Mitteln abgeschätzt werden, beispielsweise anhand des gebildeten Volumens V und/oder der gebildeten Höhe h der jeweiligen Blisterabschnitte, oder kann auch durch anerkannte Prüfmethoden ermittelt werden, beispielsweise auf der Grundlage von DIN EN ISO 527 oder dergleichen.In the production of the packaging 1 according to the invention, initially the metal-plastic composite material 10 is assumed to have the properties described above. In this material by deformation, in particular by Deep drawing, hot working or a similar deformation process, the blister sections 2 ', 4' formed, wherein the degree of deformation of Blisterabschnitts 4 'is set greater than that of Blisterabschnitts 2'. In this case, the degree of deformation can be estimated by simple means, for example based on the volume V formed and / or the height h of the blister sections formed, or can also be determined by recognized test methods, for example on the basis of DIN EN ISO 527 or the like.

Die unterschiedlichen Verformungsgrade werden derart eingestellt, dass die im Wesentlichen gasdichte (Metall-)Schicht 14 im Bereich des Blisterabschnitts 2' ihre Bruchdehnung nicht überschreitet und somit ein im Wesentlichen gasdichter Blisterabschnitt 2' erhalten wird, während bei dem Blisterabschnitt 4' die Bruchdehnung der Schicht 14 zumindest abschnittsweise überschritten wird, sodass sich Mikrorisse oder gegebenenfalls Trennrisse oder Spalte in der Schicht 14 einstellen, was dem Blisterabschnitt 4' mit steigendem Verformungsgrad eine zunehmende Gasdurchlässigkeit verleiht, wobei die Gasdurchlässigkeit zusätzlich von den Eigenschaften der weitern Schichten des Verbundmaterials abhängt.The different degrees of deformation are set such that the substantially gas-tight (metal) layer 14 in the region of the blister section 2 'does not exceed its elongation at break and thus a substantially gas-tight blister section 2' is obtained, while in the blister section 4 'the elongation at break of the layer 14 is at least partially exceeded, so that set microcracks or optionally separation cracks or gaps in the layer 14, which gives the blister section 4 'with increasing degree of deformation increasing gas permeability, wherein the gas permeability additionally depends on the properties of the further layers of the composite material.

Danach werden die gebildeten Blisterabschnitte 2', 4' mit den zu verpackenden Stoffen gefüllt, um anschließend die Deckfolien 2'', 4'' aufzulegen, die selbstverständlich auch aus einer einzigen, durchgängigen Folie gebildet sein können. Nun werden die Deckfolien 2'', 4'' mit den Rändern der Blisterabschnitte 2', 4' durch eine Siegelnaht verbunden, beispielsweise mittels Thermosiegeln, Hochfrequenzsiegeln oder Widerstandsschweißen. Dabei werden die Siegelnähte S zwischen den benachbarten Blisterabschnitten 2', 4' mit einer geringeren Siegelfestigkeit ausgeführt als die Siegelnähte R an den freien Rändern der Blisterabschnitte.Thereafter, the blister sections 2 ', 4' formed are filled with the substances to be packaged in order subsequently to place the cover films 2 '', 4 '', which can of course also be formed from a single, continuous film. Now the cover sheets 2 '', 4 '' with the edges of Blisterabschnitte 2 ', 4' connected by a sealed seam, for example by means of thermosealing, high-frequency sealing or resistance welding. In this case, the sealing seams S between the adjacent blister sections 2 ', 4' are designed with a lower sealing strength than the sealed seams R at the free edges of the blister sections.

Bei den zu verpackenden Stoffen kann es sich grundsätzlich um beliebige Stoffe handeln, wobei sich die erfindungsgemäße Verpackung 1 besonders gut für Zwei- oder Mehrkomponentenstoffe eignet, die kurz vor dem Gebrauch miteinander gemischt werden müssen und/oder ein unterschiedliches Entgasungsverhalten besitzen. Beispiele für derartige Stoffe sind kosmetische Mittel, Haarpflegemittel, Klebstoffe, Nahrungsmittel, Medikamente und dergleichen.The substances to be packaged may in principle be any substances, with the packaging 1 according to the invention being particularly well suited for two- or multi-component substances which have to be mixed together shortly before use and / or have a different degassing behavior. Examples of such substances are cosmetics, hair care products, adhesives, foods, medicines and the like.

Beim Gebrauch der erfindungsgemäßen Verpackung 1 wird zunächst durch Drücken der Blisterabschnitte 2', 4' die Siegelnaht S zwischen den benachbarten Blisterabschnitten 2', 4' durchtrennt, sodass die in den Speicherkammern 2, 4 enthaltenen Stoffe durch weiteres Drücken der Blisterabschnitte 2', 4' miteinander vermischt werden können. Anschließend können die Siegelnähte R an den freien Rändern der Blisterabschnitte 2', 4' aufgerissen oder durchtrennt werden, um die miteinander gemischten Stoffe zu entnehmen. Dabei können die miteinander gemischten Stoffe direkt auf das Anwendungsgebiet aufgetragen werden, beispielsweise Kopfhaut und Haare, ohne das zusätzliche Behälter oder dergleichen erforderlich sind.When using the packaging 1 according to the invention, the sealing seam S between the adjacent blister sections 2 ', 4' is first severed by pressing the blister sections 2 ', 4', so that the substances contained in the storage chambers 2, 4 by further pressing the Blisterabschnitte 2 ', 4th 'can be mixed together. Subsequently, the sealing seams R at the free edges of Blisterabschnitte 2 ', 4' are torn open or cut to remove the mixed substances. In this case, the substances mixed with one another can be applied directly to the field of application, for example scalp and hair, without the need for the additional container or the like.

Die vorliegende Erfindung stellt somit eine neuartige Verpackung bereit, die bei einem Minimum an Verpackungsmaterial eine sichere und dauerhafte Lagerung von Substanzen ermöglicht, die aus mehreren Komponenten bestehen, und gleichzeitig eine einfache und sichere Benutzung ermöglicht. Darüber hinaus stellt die vorliegende Erfindung ein Verfahren zur Herstellung der Verpackung bereit, das einfach uns wirtschaftliche durchführbar ist und problemlos eine Anpassung der Eigenschaften der Verpackung, insbesondere der Gasdurchlässigkeit, an die jeweils durch die zu verpackenden Stoffe gestellten Anforderungen ermöglicht.The present invention thus provides a novel packaging which, with a minimum of packaging material, allows safe and permanent storage of substances consisting of several components, while allowing easy and safe use. In addition, the present invention provides a method for producing the packaging, which is easy us economically feasible and easily allows adjustment of the properties of the packaging, in particular the gas permeability, which in each case by the substances to be packaged requirements.
