Description

Die Erfindung betrifft eine Zweikomponentenverpackung, welche besteht aus einem die Hauptkomponente aufnehmenden, einteiligen Bodenbehälter und einem die Zusatzkomponente aufnehmenden, einteiligen Kopfbehälter, der auf den Bodenbehälter auf- oder in diesen eingesetzt ist und wobei einer von diesen in Richtung auf die Begrenzungswand elastisch deformierbar ist, mit einer Applikationsspitze sowie einem, dem Durchstoßen der als Trennfolie ausgebildeten Begrenzungswand der Behälter gegeneinander dienenden und bis in die Nähe der Trennfolie reichenden Stanzwerkzeug in Form eines dem Querschnitt des Behälters angepaßten, jedoch geringfügig kleiner als dieser ausgeführten Messers, woran korbartig angeordnete Streben angeformt sind, welche sich bis in die Nähe der Wandung des das Messer umschließenden Behälters erstrecken.The invention relates to a two-component packaging, which consists of a one-part bottom container receiving the main component and a one-part head container receiving the additional component, which is placed on or in the bottom container and one of which is elastically deformable in the direction of the boundary wall. with an application tip and a punching tool which serves to puncture the boundary wall of the container, which is designed as a separating film, and which extends into the vicinity of the separating film, in the form of a knife which is adapted to the cross section of the container, but is slightly smaller than this, with struts arranged in a basket-like manner, which extend into the vicinity of the wall of the container surrounding the knife.

Bei einer Verpackung dieser Gattung entsprechend einer vorveröffentlichen Anmeldung DE-A-2 724 519 hat sich herausgestellt, daß die erst kurz von Gebrauch erfolgende Vermischung von viskosen Produkten gelegentlich schwierig ist, weil diese Produkte zu langsam ineinanderfließen.In the case of packaging of this type in accordance with a previously published application DE-A-2 724 519, it has been found that the mixing of viscous products, which has only recently been used, is sometimes difficult because these products flow into one another too slowly.

Die Aufgabe bestand deshalb darin, diese Verpackung weiter zu entwickeln, dergestalt, daß die zum Vermischen erforderliche Zeit noch wesentlich abgekürzt und die Mischintensität wesentlich verbessert wird.The task was therefore to further develop this packaging in such a way that the time required for mixing was shortened considerably and the mixing intensity was significantly improved.

Die Lösung besteht in der Ausgestaltung gemäß Anspruch 1.The solution consists in the configuration according to claim 1.

Danach ist das Stanzwerkzeug in Form eines dem Querschnitt des Behälters angepaßten Messers ausgebildet. Selbstverständlich muß das so ausgestaltete Messer geringfügig kleiner als dieser Querschnitt ausgebildet sein, damit eine Bewegung relativ zum anderen Behälter möglich ist. Weiterhin sind an das Messer korbartig angeordnete Streben angeformt.The punching tool is then designed in the form of a knife adapted to the cross section of the container. Of course, the knife designed in this way must be made slightly smaller than this cross-section so that movement relative to the other container is possible. Furthermore, struts arranged in a basket-like manner are molded onto the knife.

Es empfiehlt sich, drei oder mehr Streben gleichzeitig über den Umfang des Messers verteilt anzuordnen. Diese Ausgestaltung bewirkt einen sehr intensiven Quirfeffekt, wodurch das Vermischen der beiden Komponenten durch Umschütteln der Verpackung wirksam unterstützt wird.It is advisable to arrange three or more struts simultaneously over the circumference of the knife. This configuration produces a very intensive swirling effect, which effectively supports the mixing of the two components by shaking the packaging.

Beim Deformieren des einbeulbaren Bodens des Bodenbehälters wird gleichzeitig auch vermittels der Streben das Messer in Richtung auf die Trennfolie verlagert. Die Trennfolie wird großflächig aufgeschnitten und schafft somit für die Vereinigung beider Komponenten einen maximalen Durchtrittsquerschnitt.When deforming the dentable bottom of the bottom container, the knife is simultaneously displaced in the direction of the separating film by means of the struts. The separating film is cut open over a large area, thus creating a maximum passage cross-section for combining the two components.

Es hat sich gezeigt, daß durch die vorgeschlagene Merkmalskombination eine Mischwirkung erzielbar ist, welche derjenigen der bekannten Zweikomponentenverpackung noch überlegen ist. Die Streben sind scharfkantig ausgeführt und lediglich im oberen Drittel des Stanzwerkzeuges angeordnet. Sie bilden eine Einschnürung auf etwa dem halben Durchmesser des Stanzwerkzeuges. Die Verbindung des Stanzwerkzeuges mit dem einbeulbaren Boden des Bodenbehälters geschieht durch ein schwach konisch an das Stanzwerkzeug angeformtes Stützelement.It has been shown that the proposed combination of features can achieve a mixing effect which is still superior to that of the known two-component packaging. The struts are sharp-edged and only arranged in the upper third of the punching tool. They form a constriction on approximately half the diameter of the punch. The connection of the punching tool to the dentable bottom of the floor container is done by a weakly conically shaped support element on the punching tool.

Die den Abschluß eines der Behälter bildende Trennfolie ist eine mindestens im Randbereich beidseitig mit thermoplastischem Kunststoff beschichtete Aluminiumfolie. Diese Trennfolie verbindet mit einem den Flansch dieses Behälters überdeckenden Ringteil Bodenbehälter und Kopfbehälter dicht miteinander, wobei sich durch induktives Verschweißen eine dichte Schweißnaht im Bereich der Flansche der beiden Behälter ergibt. Der hier geschilderten Flanschverbindung kommt dabei noch besondere Bedeutung zu, weil im Flanschbereich . beide Behälter unter einer gewissen Spannung stehen, unter der beim Verschweißen der erforderliche Schweißdruck erzeugt wird. Durch Riffelung der Behälter im Flanschbereich läßt sich dieser Effekt noch verstärken.The separating film forming the end of one of the containers is an aluminum film coated at least in the edge area on both sides with thermoplastic material. This separating film connects the bottom container and the head container tightly to one another with an annular part covering the flange of this container, inductive welding resulting in a tight weld seam in the region of the flanges of the two containers. The flange connection described here is of particular importance because it is in the flange area. both containers are under a certain tension, under which the required welding pressure is generated during welding. This effect can be intensified by corrugating the containers in the flange area.

Der Vorteil der erfindungsgemäßen Zweikomponentenverpackung besteht in der überraschend verbesserten Mischwirkung gegenüber der bekannten Verpackung des Standes der Technik. Dadurch wird die erforderliche Mischzeit wesentlich abgekürzt.The advantage of the two-component packaging according to the invention lies in the surprisingly improved mixing effect compared to the known packaging of the prior art. This significantly shortens the required mixing time.

Durch die Möglichkeit der induktiven Verschweißung beider Behälter miteinander mit Hilfe der beidseitig kunststoffbeschichteten Trennfolie können Behälter aus den verschiedenartigsten Materialien miteinander verschweißt und damit die Auswahl des Materials sowohl für den Bodenwie auch den Kopfbehälter optimal auf den jeweiligen Füllstoff abgestellt werden. Es müssen also nicht mehr die Behältermaterialien als solche miteinander verschweißbar sein, sondern lediglich mit der Kuntstoffbeschichtung der Trennfolie, die jeweils einer Behälterwand anliegt. Da hinsichtlich der Kunststoffbeschichtungen der Trennfolie, die durchaus beidseitig unterschiedlich sein können, eine große Variationsbreite gegeben ist, läßt sich praktisch für jedes Behältermaterial die optimal angepaßte Trennfolie einsetzen. Der Begriff Trennfolie ist hier gewählt, weil es sich um die durch das Stanzwerkzeug zu durchtrennende Folie handelt, um die Füllsubstanzen beider Behälter miteinander zu vereinigen. Die Trennfolie erfüllt jedoch im Randbereich eine genau entgegengesetzte Funktion, nämlich die der dichten Verbindung beider Behälter untereinander. Wenn es auch ausreichend ist, die dafür eingesetzte Aluminiumfolie lediglich im Randbereich mit Kunststoff zu beschichten, weil nur dort die Kunststoffbeschichtung für die Verschweißung benötigt wird, so ist jedoch zweckmäßig die Aluminiumfolie in ihrer Gesamtheit beidseitig zu beschichten, schon allein, weil eine durchgehende Beschichtung leichter herzustellen ist.Thanks to the option of inductively welding the two containers to one another with the aid of the separating film coated with plastic on both sides, containers made from a wide variety of materials can be welded to one another and the choice of material for both the bottom and the head container can be optimally adjusted to the respective filler. It no longer has to be possible to weld the container materials as such, but only with the plastic coating of the separating film, which lies against one container wall. Since there is a wide range of variation with regard to the plastic coatings of the separating film, which can be different on both sides, the optimally adapted separating film can be used for practically every container material. The term separating film is chosen here because it is the film to be cut by the punching tool in order to combine the filling substances of both containers with one another. In the edge area, however, the separating film fulfills an exactly opposite function, namely that of the tight connection between the two containers. If it is also sufficient to coat the aluminum foil used for this with plastic only in the edge area, because only there is the plastic coating required for welding, it is advisable to coat the aluminum foil in its entirety on both sides, if only because a continuous coating is easier is to be produced.

Das Verfahren zur Herstellung der erfindungsgemäßen Zweikomponentenverpackung besteht darin, daß einer der Behälter nach dem Befüllen mit der einen Füllsubstanz mit der Trennfolie stirnseitig dicht verschweißt wird, was in üblicher Weise mit einem beheizten Schweißstempel oder ringförmigen, dem Grundriß angepaßten Schweißbacken geschieht. Nach dem Einsetzen des anderen, mit der zweiten Füllsubstanz befüllten Behälters in den Flansch werden Kopf- und Bodenbehälter von außen her induktiv dicht miteinander verschweißt.The method for producing the two-component packaging according to the invention is that one of the containers after filling with the one filler with the separating film is sealed on the end face, which is done in the usual way with a heated welding stamp or ring-shaped welding jaws adapted to the plan. After the other container filled with the second filling substance has been inserted into the flange, the top and bottom containers are inductively welded together from the outside.

Auf diese Weise können auch Packungen mit unrundem, beispielsweise ovalem und rechteckigem Grundriß einfach und sicher verschweißt werden.In this way, packs with a non-circular, for example oval and rectangular plan can also be welded easily and securely.

Boden- und Kopfbehälter bestehen aus Kunststoff mit einer Wandstärke von 0,3 bis 0,6 mm. Die Wanddicken der übrigen Behälterteile des Kopfbehälters und des Bodenbehälters sind, um diesem genug Steifigkeit zu verleihen, zweckmäßig stärker gehalten und betragen ca. 1 bis 1,5 mm. Wenn auch Kunststoff als Behältermaterial bevorzugt ist, so können Haupt- und Zusatzbehälter auch aus anderem Material bestehen, beispielsweise aus konventionellen Materialien, wie Glas und Metall, wenn das aus bestimmten Gründen zweckmäßig sein sollte, beispielsweise weil die Füllung Kunststoff angreifen würde oder die Füllsubstanzen vor oder nach der Vereinigung erhebliche Drücke entwickeln.Bottom and head containers are made of plastic with a wall thickness of 0.3 to 0.6 mm. The wall thicknesses of the other container parts of the head container and of the base container are appropriately kept thicker in order to give them sufficient rigidity and are approximately 1 to 1.5 mm. If plastic is also preferred as the container material, the main and additional containers can also consist of other material, for example conventional materials such as glass and metal, if this should be appropriate for certain reasons, for example because the filling would attack plastic or the filling substances before or develop significant pressures after merging.

Der Einsatz und die vielseitige Verwendungsmöglichkeit der erfindungsgemäßen Verpackung werden an einigen Beispielen näher erläutert, ohne daß diese erschöpfend sind. So eignet sich diese Zweikomponentenverpackung hervorragend für kosmetische Präparate, wie beispielsweise Haarfärbemittel, indem der Bodenbehälter H202-Lösung aufnimmt, der Kopfbehälter die Farbstoffcreme. Ein breites Anwendungsgebiet liegt auf dem chemischen Sektor, beispielsweise bei der Herstellung und Anwendung von Zweikomponentenklebern, z. B. auf der Basis von Epoxiden und dafür geeigneten Härtungsmitteln und bei Zweikomponentenfarben, beispielsweise für die Autolackierung.The use and versatility of the packaging according to the invention are explained in more detail using a few examples, without these being exhaustive. This two-component packaging is ideally suited for cosmetic preparations, such as hair dyes, for example, in that the bottom container absorbs H 2 0 2 solution and the head container the dye cream. A wide range of applications is in the chemical sector, for example in the manufacture and use of two-component adhesives, e.g. B. on the basis of epoxies and suitable hardening agents and in two-component paints, for example for automotive painting.

Ein anderes Einsatzgebiet ist die Herstellung von Kunststoffschäumen, wie beispielsweise Polyurethanschäumen zum Ausschäumen von Skistiefeln, Autokarosserien, Kühlzellen u. ä. In den folgenden Zeichnungen ist der Stand der Technik sowie eine Ausgestaltung der erfindungsgemäßen Verpackung beispielhaft dargestellt. Es zeigen :

  • Figur 1 den Längsschnitt durch eine bekannte Verpackung, wobei der Bodenbehälter einen ziehharmonikaartigen Bereich besitzt.
  • Figur 2 den Längsschnitt durch die erfindungsgemäße Verpackung mit einem kreisrundem Querschnitt. Der Bodenbehälter besitzt einen eindrückbaren Bereich.
  • Figur 3 die Vorderansicht der Verpackung gemäß-Fig. 2.
Another area of application is the production of plastic foams, such as polyurethane foams for foaming ski boots, car bodies, cold rooms and the like. In the following drawings, the prior art and an embodiment of the packaging according to the invention is shown as an example. Show it :
  • Figure 1 shows the longitudinal section through a known packaging, the floor container has an accordion-like area.
  • Figure 2 shows the longitudinal section through the packaging according to the invention with a circular cross section. The bottom container has an indentable area.
  • 3 shows the front view of the packaging according to - Fig. 2.

Eine aus spritz- oder blasfähigen Thermoplasten hergestellte bekannte Verpackung wie in DE-A-2 724 519 beschrieben, besteht aus dem einteiligen Bodenbehälter 2 für die Hauptkomponente-1 (Fig. 1) und dem die Zusatzkomponente 11 aufnehmenden, einteiligen Kopfbehälter 3. Durch mehrmaliges Eindrücken des Bodenbehälters 2, welcher nach Aufhören des Druckes jeweils in seine Ausgangslage zurückkehrt, kann eine Pumpwirkung erzielt werden. Die Wandstärke des Bodenbehälters 2 beträgt etwa 0,3 bis 0,5 mm.A known packaging made of injection-moldable or blow-molding thermoplastics, as described in DE-A-2 724 519, consists of the one-piece bottom container 2 for the main component-1 (FIG. 1) and the one-piece head container 3 receiving the additional component 11 Pressing in the bottom container 2, which returns to its starting position after the pressure has ceased, a pumping effect can be achieved. The wall thickness of the bottom container 2 is approximately 0.3 to 0.5 mm.

Es ist ferner das Messer 12 vorhanden, welches dem Durchstoßen der Trennfolie 7 dient. Die Folie 7 besteht aus Aluminium und ist beidseitig mit thermoplastischem Kunststoff beschichtet. Das Messer 12 ist dem Querschnitt des Kopfbehälters 3 angepaßt. Der Querschnitt des Messers 12 ist jedoch geringfügig kleiner als der Querschnitt des Bodenbehälters 2. Dadurch kann das Messer 12 in Richtung auf die Trennfolie 7 verlagert werden. Das Messer 12 ist weiterhin durch die korbartig angeordneten Streben 6 gegen das Unterteil des Bodenbehälters 2 abgestützt. Die Streben 6 mit dem Messer 12 nehmen in der Höhe gesehen nahezu den ganzen Innenraum des Kopfbehälters 3 ein. Beim Eindrücken des Bodenbehälters 2 trennt das Messer 12 die Trennfolie 7 durch.There is also a knife 12 which serves to pierce the separating film 7. The film 7 consists of aluminum and is coated on both sides with thermoplastic. The knife 12 is adapted to the cross section of the head container 3. However, the cross section of the knife 12 is slightly smaller than the cross section of the bottom container 2. As a result, the knife 12 can be displaced in the direction of the separating film 7. The knife 12 is further supported by the struts 6 arranged in a basket-like manner against the lower part of the base container 2. Seen in height, the struts 6 with the knife 12 occupy almost the entire interior of the head container 3. When the bottom container 2 is pressed in, the knife 12 cuts through the separating film 7.

Die Streben 6 sind scharfkantig ausgebildet und an ihrem, dem Messer 12 abgewandten Ende untereinander durch Stege verbunden. Das Messer 12 weist an der Stelle 14 eine Stumpfzone auf. An dieser Stelle erfolgt kein Durchtrennen der Folie 7. Die Folie 7 kann nach dem Ausschneiden nicht die Austrittsöffnung der Applikationsspitze 4 versperren, weil sie scharnierartig mit dem Kopfbehälter 3 verbunden ist.The struts 6 are formed with sharp edges and are connected to one another by webs at their end facing away from the knife 12. The knife 12 has a stump zone at the point 14. At this point there is no cutting through of the film 7. After cutting out, the film 7 cannot block the outlet opening of the application tip 4 because it is connected to the head container 3 like a hinge.

Nach Eindrücken des Bodenbehälters 2 wird die Folie 7 nahezu vollständig ausgestanzt. Die Zusatzkomponente 11 gelangt in den Behälter 2, wo eine Vermischung mit der Hauptkomponente 1 stattfindet. Durch Umschüttein der Verpackung und damit Wirksamwerden der Streben 6 als Mischelemente stellt sich eine homogene Mischung ein.After pressing in the bottom container 2, the film 7 is punched out almost completely. The additional component 11 enters the container 2, where mixing with the main component 1 takes place. By shaking the packaging and thus the struts 6 becoming effective as mixing elements, a homogeneous mixture is established.

Bei der bekannten Verpackung gemäß Fig. 1 besitzt der Bodenbehälter 2 einen ziehharmonikaartigen Bereich 15.In the known packaging according to FIG. 1, the bottom container 2 has an accordion-like area 15.

Das Stanzwerkzeug 6, 12 befindet sich in dem Bodenbehälter 2. Das Stanzwerkzeug 6, 12 ist ferner bei 21 am Boden des Behälters 2 arretiert. Es sind ferner Zentriernasen 16 zum Zentrieren des Messers 12 vorgesehen. Der Kopfbehälter 3 ist durch die Trennfolie 7 verschlossen. Die Trennfolie 7 überdeckt den Behälter 3 und verbindet den Bodenbehälter 2 und den Kopfbehälter 3 dicht miteinander. Im Bereich der Flansche 18, 19 ergibt sich nämlich durch induktives Verschweißen eine dichte Schweißnaht.The punch 6, 12 is located in the bottom container 2. The punch 6, 12 is also locked at 21 on the bottom of the container 2. Centering lugs 16 are also provided for centering the knife 12. The head container 3 is closed by the separating film 7. The separating film 7 covers the container 3 and connects the bottom container 2 and the head container 3 tightly to one another. In the area of the flanges 18, 19 there is namely a tight weld seam by inductive welding.

Zum Durchtrennen der Trennfolie 7 wird der Bodenbehälter 2 zusammengedrückt, um gegebenenfalls zusätzlich noch einen Pumpeffekt zu erzielen.
