Definitions
- the invention relates to a dispenser for a two-component adhesive with two chambers provided for receiving one of the components with the mixing ratio of the components corresponding volume ratio, the chamber bottoms being designed as pistons for simultaneously pressing out the chamber contents.
- a dispenser configuration for dispensing toothpaste and similar pasty products is also known from FR - A 1 123 773.
- the containers can have different cross-sectional shapes.
- the product is fed by means of a piston.
- the piston can for example be arranged within a tube and have a wedge shape.
- the piston is then moved axially forward by pressure on the tube end and drives the product mass to the outlet opening. It is also possible to actuate the piston from the outside by means of a threaded spindle.
- an embodiment can be selected, the piston being under spring tension.
- the spring can be relieved from the outside by means of a chain as required, which then drives the piston in the direction of the outlet opening.
- FR - PS 763 219 Also known from FR - PS 763 219 is a dispenser construction for dosing two types of different creams.
- This dispenser has two compartments intended to hold one cream each. The two amounts of cream are brought together in the head of the dispenser and mixed there.
- the chamber bottoms are designed as pistons, each of which can be moved forward individually.
- a dispenser has also become known from US Pat. No. 3,330,444, which allows the dosing of, for example, two-component epoxy resin.
- the arrangement is such that two chambers are provided for receiving one of each component.
- the chambers have a volume ratio which corresponds to the mixing ratio of the component.
- the chamber bottoms are designed as pistons for simultaneously pressing out the chamber contents.
- the invention is based on the object, based on this known construction, of creating a less complex packaging for a two-component adhesive, which likewise enables targeted dosing of the two components with simple handling and which is less susceptible to failure despite less effort.
- the solution of the above object is that the chambers are separated in a container shaped as a straight prism by dividing the interior thereof by a partition wall parallel to the longitudinal axis of the prism and displaceable in the direction of this axis, so that the bottom surfaces of the Pistons forming chambers are attached laterally to the lower end of the intermediate wall facing the bottom of the container and that the intermediate wall has at least one cam which can be actuated from the outside of the container for displacing the intermediate wall in the direction parallel to the longitudinal axis of the prism.
- the container according to the invention is preferably cuboid.
- the intermediate wall can then extend perpendicular to the wide side faces of the cuboid and parallel to its narrow side faces. It has proven to be advantageous if a cam attached to the intermediate wall, which is provided for displacing the intermediate wall in the direction of the longitudinal axis of the prism, projects outwards through a longitudinal slot made in one of the wide side surfaces of the container, which slit (in the side surface) lengthways one edge of the partition.
- the invention accordingly is a container ter has been created, the interior of which is separated into two compartments in the simplest way, namely by an intermediate wall formed by a side piston.
- the division can be made exactly in the intended mixing ratio of the two components, for example resin and hardener.
- the intermediate wall and the pistons attached laterally at its lower end form a single component according to the invention, so expensive means for simultaneous actuation of the pistons are no longer required.
- the product or the individual components can be wiped off with a spatula on the preferably flat upper edge of the container - up to the intermediate wall in each case.
- the partition thus prevents the (unintentional) mixing of the respective residual amounts in the container even when the product is removed.
- the partition and thus the remaining amount of the two components can be pushed back into the container and the packaging closed with a lid.
- the dispenser according to the invention consists of a cuboid-shaped container 1, an intermediate wall 2 and a lid 3.
- a slot 5 is provided in one large side surface 4, through which a cam 6 connected to the intermediate wall 2 extends outwards protrudes. By moving the cam 6 in the direction of arrow 7, the intermediate wall 2 running parallel to the narrow side surfaces 8 is moved.
- pistons 9 and 10 are attached laterally to the lower end of the intermediate wall and form the bottom of the two chambers 11 and 12 (FIG. 1) of the container 1 separated by the intermediate wall 2.
- the intermediate wall 2 When the intermediate wall 2 is actuated by moving the cam 6 in the direction of the arrow 7, the contents of both chambers 11 and 12, namely the first component 13 and the second component 14, can be pushed upwards or outwards simultaneously.
- the contents of the container 1 reach an area above the scraper edges 15 and 16 and can be removed, for example with a spatula. Since the intermediate wall 2 is also moved out of the container 1 when components 13 and 14 are pressed out, mixing of the two components 13 and 14 and, in particular, the respective residual amount in the chambers 11 and 12 cannot occur (unintentionally) even when the product is removed.
- the intermediate wall 2 can be pushed downward again by actuating the cam 6 in the direction of the arrow 7, the content of the two chambers 11 and 12 generally being drawn along.
- the lid 3 can be put on as shown in FIG. 2, so that there is no risk of the container contents drying out.

Description
Die Erfindung betrifft einen Spender für einen Zweikomponentenkleber mit zwei zur Aufnahme je einer der Komponenten vorgesehenen Kammern mit dem Mischungsverhältnis der Komponenten entsprechendem Volumenverhältnis, wobei die Kammerböden als Kolben zum gleichzeitigen Herauspressen des Kammerinhalts ausgebildet sind.The invention relates to a dispenser for a two-component adhesive with two chambers provided for receiving one of the components with the mixing ratio of the components corresponding volume ratio, the chamber bottoms being designed as pistons for simultaneously pressing out the chamber contents.
Bei bisherigen Verpackungen für zwei getrennt vorliegende Komponenten eines Klebers, zum Beispiel Doppelkammern, Tube und Kammer, Doppeltube, zwei Tuben oder Doppelflasche, erfolgen das Entnehmen und Vermischen der Komponenten mit Hilfe eines Spachtels. Die beiden Komponenten werden dabei in den meisten Fällen lediglich visuell dosiert. Bei einem Zweikomponentenklebstoff kann daher eine optimale Klebefestigkeit meist nur durch Zufall erreicht werden.With previous packaging for two separate components of an adhesive, for example double chambers, tube and chamber, double tube, two tubes or double bottle, the components are removed and mixed using a spatula. In most cases, the two components are only dosed visually. With a two-component adhesive, optimal adhesive strength can usually only be achieved by chance.
Es ist auch schon versucht worden, einen Doppelbehälter mit zwei nebeneinanderliegenden Zylindern und Kolben herzustellen, wobei das Volumenverhältnis der Zylinderkammern dem gewünschten Mischungsverhältnis der Komponenten entspricht. Die beiden Komponenten können dabei gleichzeitig mit Hilfe der Kolben aus den Zylindern ausgepreßt werden. Zum Betätigen der Kolben können beispielsweise zwei 'mit je einem der Kolben und untereinander über Zahnräder in Eingriff stehende Spindeln vorgesehen sein. Der Inhalt der beiden Zylinder kann daher gleichzeitig durch Drehen an den Zahnrädern und damit durch Vorschieben der Kolben aus den Zylindern - in der jeweils gewünschten Menge - ausgepreßt werden. Auf diese Weise ist zwar eine Zwangsdosierung der beiden Komponenten möglich, der Aufbau des Behälters mit den beiden getrennten zylinderförmigen Kammern ist aber so aufwendig, daß eine wirtschaftlich vertretbare Anwendung kaum in Frage kommt. Außerdem besteht am Kopf des Behälters, an dem die Komponenten entnommen werden, stets die Gefahr einer ungewollten Vermischung der jeweiligen Restmenge der Komponenten.Attempts have also already been made to produce a double container with two cylinders and pistons lying next to one another, the volume ratio of the cylinder chambers corresponding to the desired mixing ratio of the components. The two components can be pressed out of the cylinders simultaneously using the pistons. To actuate the pistons, for example, two spindles, each of which engages with one of the pistons and with one another via gear wheels, can be provided. The contents of the two cylinders can therefore be pressed out at the same time by rotating the gearwheels and thus by pushing the pistons out of the cylinders in the desired quantity. In this way, a forced metering of the two components is possible, but the construction of the container with the two separate cylindrical chambers is so complex that an economically justifiable application is hardly possible. In addition, there is always the risk of undesired mixing of the respective remaining amount of the components at the head of the container from which the components are removed.
Eine Spenderausgestaltung für die Abgabe von Zahnpasta und ähnlichen pastösen Produkten ist auch aus der FR - A 1 123 773 bekannt. Dabei können die Behälter unterschiedliche Querschnittsformen aufweisen. Der Produktvorschub geschieht mittels eines Kolbens. Der Kolben kann beispielsweise innerhalb einer Tube angeordnet sein und Keilform besitzen. Durch Druck auf das Tubenende wird der Kolben dann axial vorwärtsbewegt und treibt die Produktmasse zur Austrittsöffnung. Es ist auch möglich, den Kolben vermittels Gewindespindel von außen zu betätigen. Schließlich kann eine Ausgestaltung gewählt werden, wobei der Kolben unter Federspannung steht. Die Feder kann vermittels einer Kette von außen je nach Erfordernis entlastet werden, wodurch dann der Kolben in Richtung Austrittsöffnung vorgetrieben wird.A dispenser configuration for dispensing toothpaste and similar pasty products is also known from FR - A 1 123 773. The containers can have different cross-sectional shapes. The product is fed by means of a piston. The piston can for example be arranged within a tube and have a wedge shape. The piston is then moved axially forward by pressure on the tube end and drives the product mass to the outlet opening. It is also possible to actuate the piston from the outside by means of a threaded spindle. Finally, an embodiment can be selected, the piston being under spring tension. The spring can be relieved from the outside by means of a chain as required, which then drives the piston in the direction of the outlet opening.
Bekannt ist ferner aus der FR - PS 763 219 eine Spenderkonstruktion für die Dosierung von zwei Sorten verschiedener Cremes. Dieser Spender besitzt zwei zur Aufnahme von je einer Creme vorgesehene Kammern. Die beiden Crememengen werden im Kopf des Spenders zusammengefuhrt und dort vermischt. Die Kammerböden sind als Kolben ausgebildet, welcher jeder für sich - also individuell - vorwärtsbewegt werden kann.Also known from FR - PS 763 219 is a dispenser construction for dosing two types of different creams. This dispenser has two compartments intended to hold one cream each. The two amounts of cream are brought together in the head of the dispenser and mixed there. The chamber bottoms are designed as pistons, each of which can be moved forward individually.
Schließlich ist auch ein Spender aus der US - PS 33 30 444 bekannt geworden, welcher die Dosierung beispielsweise von Zwikomponenten-Epexid-Harz gestattet. Die Anordnung ist dabei dergestalt getroffen, daß zwei Kammern zur Aufnahme je einer der Komponente vorgesehen ist. Die Kammern weisen ein Volumenverhältnis auf, welches dem Mischungsverhältnis der Komponente entspricht. Die Kammerböden sind als Kolben zum gleichzeitigen Herauspressen des Kammerinhaltes ausgebildet.Finally, a dispenser has also become known from US Pat. No. 3,330,444, which allows the dosing of, for example, two-component epoxy resin. The arrangement is such that two chambers are provided for receiving one of each component. The chambers have a volume ratio which corresponds to the mixing ratio of the component. The chamber bottoms are designed as pistons for simultaneously pressing out the chamber contents.
Der Erfindung liegt demgegenüber die Aufgabe zugrunde, ausgehend von dieser bekannten Konstruktion, eine weniger aufwendige Verpackung für einen Zweikomponentenklebstoff zu schaffen, die ebenfalls ein gezieltes Dosieren der beiden Komponenten bei einfacher Handhabung ermöglicht und die trotz geringeren Aufwandes weniger störanfällig ist.In contrast, the invention is based on the object, based on this known construction, of creating a less complex packaging for a two-component adhesive, which likewise enables targeted dosing of the two components with simple handling and which is less susceptible to failure despite less effort.
Zu dem Spender eingangs genannter Art besteht die erfindungsgemäße Lösung vorstehender Aufgabe darin, daß die Kammern in einem als gerades Prisma geformten Behälter durch Abteilen von dessen Innenraum durch eine parallel zur Prismalängsachse stehende und in Richtung dieser Achse verschiebbare Zwischenwand getrennt sind, daß die die Bodenflächen der Kammern bildenden Kolben seitlich an das dem Boden des Behälter zugewandte untere Ende der Zwischenwand angesetzt sind und daß die Zwischenwand mindestens eine von der Außenseite des Behälters her betätigbare Nocke zum Verschieben der Zwischenwand in der Richtung parallel zur Prismalängsachse aufweist.To the dispenser of the type mentioned above, the solution of the above object is that the chambers are separated in a container shaped as a straight prism by dividing the interior thereof by a partition wall parallel to the longitudinal axis of the prism and displaceable in the direction of this axis, so that the bottom surfaces of the Pistons forming chambers are attached laterally to the lower end of the intermediate wall facing the bottom of the container and that the intermediate wall has at least one cam which can be actuated from the outside of the container for displacing the intermediate wall in the direction parallel to the longitudinal axis of the prism.
Der erfindungsgemäße Behälter ist vorzugsweise quaderförmig ausgebildet. Die Zwischenwand kann sich dann senkrecht zu den breiten Seitenflächen des Quaders sowie parallel zu dessen schmalen Seitenflächen erstrecken. Dabei hat es sich als günstig erwiesen, wenn eine an die Zwischenwand angesetzte Nocke, die zum Verschieben der Zwischenwand in Richtung der Prismalängsachse vorgesehen ist, durch einen in eine der breiten Seitenflächen des Behälters eingebrachten Längsschlitz nach außen vorspringt, welcher (in der Seitenfläche) längs einer Kante der Zwischenwand verläuft.The container according to the invention is preferably cuboid. The intermediate wall can then extend perpendicular to the wide side faces of the cuboid and parallel to its narrow side faces. It has proven to be advantageous if a cam attached to the intermediate wall, which is provided for displacing the intermediate wall in the direction of the longitudinal axis of the prism, projects outwards through a longitudinal slot made in one of the wide side surfaces of the container, which slit (in the side surface) lengthways one edge of the partition.
Durch die Erfindung ist demgemäß ein Behälter geschaffen worden, dessen Innenraum auf einfachste Weise, nämlich durch eine verschiebbare, mitseitlichem Kolben ausgebildete Zwischenwand, in zwei Abteile getrennt ist. Die Teilung kann dabei exakt in dem vorgesehenen Mischungsverhältnis der beiden Komponenten, zum Beispiel von Harz und Härter, vorgenommen werden. Durch Verschieben der Zwischenwand - in ihrer Fläche - mit Hilfe des außenliegenden Nockens wird eine Zwangsdosierung erreicht, so daß jede gewünschte Produktmenge in immer gleichem Mischungsverhältnis aus dem Behälter auspreßbar ist.The invention accordingly is a container ter has been created, the interior of which is separated into two compartments in the simplest way, namely by an intermediate wall formed by a side piston. The division can be made exactly in the intended mixing ratio of the two components, for example resin and hardener. By moving the partition - in its surface - with the help of the external cam, a forced dosage is achieved so that any desired amount of product can always be squeezed out of the container in the same mixing ratio.
Gegenüber früheren Vorschlägen ist dabei wesentlich, daß die Zwischenwand und die an deren unteres Ende seitlich angesetzten Kolben erfindungsgemäß ein einziges Bauteil bilden, aufwendige Mittel zum gleichzeitigen Betäti- gen der Kolben sind also nicht mehr erforderlich. Beim Anwenden kann das Produkt bzw. können die einzelnen Komponenten mit Hilfe eines Spachtels an der vorzugsweise planen Oberkante des Behälters - bis jeweils zur Zwischenwand - abgestreift werden. Die Zwischenwand verhindert somit auch beim Entnehmen des Produkts ein (ungewolltes) Vermischen der jeweiligen Restmengen im Behälter.Compared to previous proposals, it is essential that the intermediate wall and the pistons attached laterally at its lower end form a single component according to the invention, so expensive means for simultaneous actuation of the pistons are no longer required. When used, the product or the individual components can be wiped off with a spatula on the preferably flat upper edge of the container - up to the intermediate wall in each case. The partition thus prevents the (unintentional) mixing of the respective residual amounts in the container even when the product is removed.
Nach dem Entnehmen des Produkts können die Zwischenwand und somit auch die Restmenge der beiden Komponenten wieder in den Behälter eingeschoben sowie die Verpackung mit einem Deckel verschlossen werden.After removing the product, the partition and thus the remaining amount of the two components can be pushed back into the container and the packaging closed with a lid.
Anhand der schematischen Darstellung eines Ausführungs-beispiels werden weitere Einzelheiten der Erfindung erläutert. Es zeigen:
- Fig. 1 einen geöffneten Behälter mit abgehobener Zwischenwand; und
- Fig. 2 den verschlossenen Spender und teilweise dessen Inneres.
- Figure 1 shows an open container with a raised partition. and
- Fig. 2 shows the closed dispenser and partially its interior.
Der erfindungsgemäße Spender besteht gemäß Ausführungsbeispiel nach Fig. 1 und 2 aus einem quaderförmigen Behälter 1, einer Zwischenwand 2 und einem Deckel 3. In der einen großen Seitenfläche 4 ist ein Schlitz 5 vorgesehen, durch den eine mit der Zwischenwand 2 verbundene Nocke 6 nach außen ragt. Durch Verschieben der Nocke 6 in Pfeilrichtung 7 wird die parallel zu den schmalen Seitenflächen 8 verlaufende Zwischenwand 2 bewegt.1 and 2, the dispenser according to the invention consists of a cuboid-shaped container 1, an
Wie aus Fig. 2 ersichtlich, sind an das untere Ende der Zwischenwand 2 Kolben 9 und 10 seitlich angesetzt, die den Boden der beiden durch die Zwischenwand 2 getrennten Kammern 11 und 12 (Fig. 1) des Behälters 1 bilden. Beim Betätigen der Zwischenwand 2 durch Verschieben der Nocke 6 in Pfeilrichtung 7 kann der Inhalt beider Kammern 11 und 12, nämlich die erste Komponente 13 und die zweite Komponente 14, gleichzeitig nach oben bzw. außen geschoben werden. Der Inhalt des Behälters 1 gelangt dabei in einen Bereich oberhalb der Abstreifkanten 15 und 16 und kann, beispielsweise mit einem Spachtel, abgenommen werden. Da die Zwischenwand 2 beim Herauspressen der Komponenten 13 und 14 ebenfalls aus dem Behälter 1 ausgefahren wird, kann auch beim Entnehmen des Produkts ein Vermischen der beiden Komponenten 13 und 14 un insbesondere der jeweiligen Restmenge in den Kammern 11 und 12 nicht (ungewollt) eintreten.As can be seen from FIG. 2,
Jeweils nach dem Entnehmen von Produkt aus dem erfindungsgemäßen Behälter 1 kann die Zwischenwand 2 durch Betäti-gen der Nocke 6 in Pfeilrichtung 7 wieder nach unten geschoben werden, wobei der Inhalt der beiden Kammern 11 und 12 in der Regel mitgezogen wird. Bei vollständig wieder abgesenkter Zwischenwand 2 kann gemäß Fig. 2 der Deckel 3 aufgesetzt werden, so daß die Gefahr eines Austrocknens des Behälterinhalts nicht besteht.
