Description

Die vorliegende Erfindung betrifft einen Behälter für pastöse Massen, bestehend aus einem zylindrischen Gehäuse und einer Ausdrückanordnung, wobei das Gehäuse durch eine in Längsrichtung angeordnete Trennwand in zwei separate Kammern unterteilt ist, wobei am oberen Ende einer jeden Kammer jeweils eine Ausblasöffnung vorgesehen ist, auf die eine Mischspitze bzw. ein Verschlußstopfen aufschraubbar ist und wobei in jeder Kammer ein halbkreisförmiger Kolben vorgesehen ist, der in Richtung zur Auslaßöffnung verschiebbar ist.The present invention relates to a container for pasty masses, consisting of a cylindrical housing and a push-out arrangement, the housing being divided into two separate chambers by a longitudinally arranged partition wall, a blow-out opening being provided at the upper end of each chamber a mixing tip or a sealing plug can be screwed on, and in each chamber a semicircular piston is provided which is displaceable in the direction of the outlet opening.

Es sind bereits Behälter mit Vorrichtungen zur dosierten Abgabe von pastösen oder viskosen Massen bekannt, bei denen gewöhnlich ein verschiebbarer Kolben innerhalb des im allgemeinen rohrförmigen Behälters vorhanden ist. Mit derartigen Behältern können Einkomponentenmassen, wie z.B. Klebstoffe, dosiert aufgetragen werden.Containers with devices for the metered delivery of pasty or viscous masses are already known, in which a displaceable piston is usually present within the generally tubular container. With such containers one-component masses, e.g. Adhesives, applied in doses.

Bei der Verwendung von Zweikomponentengemischen, wie z.B. Klebstoffen, wurden üblicherweise zwei derartige Behälter verwendet, da die beiden Komponenten vor dem Gebrauch nicht miteinander in Berührung gebracht werden dürfen und demzufolge in zwei separaten Behältern aufbewahrt werden müssen, aus denen sie bei Gebrauch getrennt aufgetragen und miteinander vermischt werden müssen. Eine derartige Handhabung ist jedoch umständlich und zeitaufwendig.When using two-component mixtures, e.g. Adhesives, two such containers have usually been used since the two components must not be brought into contact with one another before use and consequently must be kept in two separate containers, from which they must be applied separately and mixed together during use. Such handling is cumbersome and time consuming.

Um diese Nachteile zu vermeiden, wurde bereits in der CH-­PS 659 629 ein Behälter für pastöse Massen der eingangs näher genannten Art vorgeschlagen, mit dem die beiden Kom­ponenten eines Zweikomponentengemisches separat aufbewahrt und gleichzeitig abgegeben werden können und der einfach im Aufbau und billig in der Herstellung ist. Die beiden ge­trennt aufbewahrten Komponenten z.B. eines Zweikomponenten-­Klebstoffs werden durch eine geeignete Auspreßvorrichtung gleichzeitig in eine aufschraubbare Mischspitze gefördert und dort gründlich miteinander vermischt bevor sie an der entsprechenden Klebstelle aufgetragen werden. Durch die gleichzeitige Betätigung z.B. zweier halbkreisförmiger Kol­ben mittels einer gemeinsamen Druckvorrichtung wird sicher­gestellt, daß jeweils eine gleich große Menge aus den bei­den Kammern abgegeben wird, so daß das Mischungsverhältnis konstant ist.In order to avoid these disadvantages, a container for pasty masses of the type mentioned in the introduction was already proposed in CH-PS 659 629, with which the two components of a two-component mixture can be stored separately and released at the same time and which is simple in construction and inexpensive to use Manufacturing is. The two separately stored components, for example a two-component adhesive, are separated by a suitable squeezing device at the same time conveyed into a screw-on mixing tip and mixed there thoroughly before they are applied to the appropriate gluing point. The simultaneous actuation, for example, of two semicircular pistons by means of a common pressure device ensures that an equal amount is dispensed from the two chambers, so that the mixing ratio is constant.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ei­nen derartigen Behälter für pastöse Massen dahingehend zu verbessern, daß eine optimale Abdichtung der Kolben inner­halb der Kammern gewährleistet ist, um so auch nach länge­rem Gebrauch den Zutritt von Luft zuverlässig zu verhin­dern.The present invention has for its object to improve such a container for pasty masses in such a way that an optimal sealing of the pistons is ensured within the chambers, so as to reliably prevent the entry of air even after prolonged use.

Ausgehend von einem Behälter der eingangs näher genannten Art wird zur Lösung dieser Aufgabe vorgeschlagen, daß die mit der pastösen Masse in Berührung stehende Oberfläche des Kolbenbodens eine Wölbung in Richtung zur pastösen Masse hin aufweist, daß auf der Unterseite des Kolbenbo­dens mehrere Rippen vorgesehen sind zur Aufnahme einer Aus­drückplatte und daß entlang des Außenrandes des Kolbenbo­dens eine Dichtungslippe vorgesehen ist, deren Außenfläche unter einem Winkel zur Kolbenwand angeordnet ist und die sich über die Kolbenwand hinaus erstreckt.Starting from a container of the type mentioned in the introduction, it is proposed to solve this problem that the surface of the piston crown in contact with the pasty mass has a curvature in the direction of the pasty mass, that several ribs are provided on the underside of the piston crown for receiving an ejection plate and that a sealing lip is provided along the outer edge of the piston crown, the outer surface of which is arranged at an angle to the piston wall and which extends beyond the piston wall.

Die Rippen können vorteilhafterweise unterschiedliche Höhen aufweisen , wobei bei einem bevorzugten Ausführungs­beispiel vier Rippen vorgesehen sind, von denen die beiden innenliegenden Rippen eine geringere Höhe als die beiden außenliegenden Rippen aufweisen.The ribs can advantageously have different heights, four ribs being provided in a preferred exemplary embodiment, of which the two inner ribs have a lower height than the two outer ribs.

Vorteilhafterweise ist zwischen den Rippen wenigstens ein kreisförmiges Verstärkungsteil angeordnet.At least one circular reinforcement part is advantageously arranged between the ribs.

Die Winkel der Außenfläche der Dichtungslippe mit der Kol­benwand kann zwischen 10° und 30° liegen und beträgt vor­zugsweise 20°.The angle of the outer surface of the sealing lip with the piston wall can be between 10 ° and 30 ° and is preferably 20 °.

Mit der erfindungsgemäßen Ausgestaltung der Kolben wird der Vorteil erzielt, daß beim Anliegen der Ausdrückplatte auf die Rippen großer Höhe durch die Wölbung des Kolben­bodens ein Gegendruck auf die Dichtungslippe ausgeübt wird, wodurch der Durchmesser des Kolbens erhöht wird. Die­se Erweiterung des Kolbendurchmessers gewährt während des Auspreßvorgangs eine optimale Dichtung zwischen Kolben und Behälterinnenwand.With the design of the piston according to the invention, the advantage is achieved that when the pressure plate rests on the ribs of great height, a counter pressure is exerted on the sealing lip by the curvature of the piston crown, which increases the diameter of the piston. This expansion of the piston diameter ensures an optimal seal between the piston and the inner wall of the container during the extrusion process.

Im folgenden wird die Erfindung anhand der Zeichnung näher erläutert, in der ein vorteilhaftes Ausführungsbeispiel dargestellt ist. Es zeigen:

  • Figur 1 einen Schnitt durch einen erfindungsgemäßen Kolben;
  • Figur 2 eine Unteransicht dieses Kolbens;
  • Figur 3 einen Schnitt durch einen Behälter für pastöse Massen entlang der Trennwand, der mit den beiden erfindungsgemäßen Kolben zu versehen ist;
  • Figur 4 einen Schnitt, der um 90° versetzt zu demjenigen von Figur 3 ist;
  • Figur 5 einen Schnitt durch einen Verschlußstöpsel;
  • Figur 6 eine Draufsicht auf den Behälter und
  • Figur 7 eine Einzelheit der Befestigung des Verschlußstöp­sels.
The invention is explained in more detail below with reference to the drawing, in which an advantageous exemplary embodiment is shown. Show it:
  • 1 shows a section through a piston according to the invention;
  • Figure 2 is a bottom view of this piston;
  • Figure 3 shows a section through a container for pasty masses along the partition, which is to be provided with the two pistons according to the invention;
  • FIG. 4 shows a section which is offset by 90 ° to that of FIG. 3;
  • Figure 5 shows a section through a plug;
  • Figure 6 is a plan view of the container and
  • Figure 7 shows a detail of the fastening of the closure plug.

Bei dem in Figur 1 dargestellten Schnitt durch einen erfin­dungsgemäßen halbkreisförmigen Kolben, wie er zum Einsatz in einer Zweikomponenten-Kartusche nach Figur 3 vorgesehen ist, ist mit 1 eine nach oben gerichtete, d.h. in Kontakt mit der pastösen Masse stehende Wölbung des Kolbenbodens 8 bezeichnet. Der Kolbenboden wird entlang seines Umfangs durch eine senkrechte Kolbenwand 4 begrenzt, deren Wand­stärke c z.B. 2 mm beträgt.In the section shown in FIG. 1 through a semicircular piston according to the invention, as is intended for use in a two-component cartridge according to FIG. 3, 1 denotes an upward, i.e. referred to in contact with the pasty mass curvature of the piston crown 8. The piston crown is delimited along its circumference by a vertical piston wall 4, the wall thickness c of which is e.g. Is 2 mm.

Auf der Unterseite des Kolbenbodens 8 und innerhalb der Kolbenwand 4 sind mehrere Rippen vorgesehen, wobei im gewählten Ausführungsbeisiel vier Rippen 5, 5′, 6, 6′ dargestellt sind. Diese Rippen verbinden den halbkreisför­migen Teil der Kolbenwand 4 mit dem dem Kreisdurchmesser entsprechenden Teil der Kolbenwand, so daß sich auf ihnen eine ebenfalls halbkreisförmige Ausdrückplatte abstützen kann, die den Kolben in Richtung der Auslaßöffnung verschiebt.
Wie Figur 1 zu entnehmen ist, weisen dabei zwei Rippen, in diesem Fall die beiden außenliegenden Rippen 5, 5′ eine größere Höhe auf als die beiden innenliegenden Rippen 6, 6′, so daß bei der ersten Berührung der Ausdrückplatte mit dem Kolben diese sich zuerst auf den Rippen 5, 5′ abstützt, nachdem diese in die Kolbenwand 4 eingefahren worden ist.
On the underside of the piston crown 8 and within the piston wall 4, several ribs are provided, four ribs 5, 5 ', 6, 6' being shown in the selected embodiment. These ribs connect the semicircular part of the piston wall 4 to the part of the piston wall corresponding to the circular diameter, so that a likewise semicircular ejection plate can be supported on them, which displaces the piston in the direction of the outlet opening.
As can be seen in Figure 1, two ribs, in this case the two outer ribs 5, 5 'have a greater height than the two inner ribs 6, 6', so that when the ejection plate touches the piston for the first time, the latter first supported on the ribs 5, 5 'after it has been inserted into the piston wall 4.

Entlang des Außenumfangs des Kolbenbodens 8 ist weiterhin eine Dichtungslippe 2 vorgesehen, die derart angeordnet ist, daß ihre Außenfläche 3 sich über den Durchmesser der Wand 4 hinauserstreckt und unter einem Winkel α zur Wand 4 angeordnet ist.Along the outer circumference of the piston crown 8, a sealing lip 2 is further provided, which is arranged such that its outer surface 3 extends beyond the diameter of the wall 4 and is arranged at an angle α to the wall 4.

Mit 7 ist ein kreisförmiges Verstärkungsteil bezeichnet, das z.B. zwishcen den beiden innenliegenden Rippen 6, 6′ fest angeordnet ist.7 with a circular reinforcing part is designated, for example between the two inner ribs 6, 6 'is fixedly arranged.

Die beiden nebeneinander in den beiden getrennten Kammern des Behälters angeordneten Kolben gemäß Figuren 1 und 2 werden parallel zueinander von jeweils einer Ausdrückplatte in Richtung zur Auslaßöffnung verschoben, die in die Kolbenwand 4 eingreift und sich bei Erstkontakt auf den Rippen größerer Höhe 5, 5′ abstützt. Während jeder Kolben nach vorne geschoben wird, erzeugt die Wölbung 1 einen Gegendruck auf die Dichtungslippe 2, wodurch der Durchmes­ser des Kolbens auf Höhe der Dichtungslippe vergrößert wird und dabei eine optimale Abdichtung innerhalb der Kammern erzielt wird. Der Druck kann dabei so weit erhöht werden, bis die Rippen größerer Höhe 5, 5′ zusammengedrückt werden und sich die (nicht dargestellte) Ausdrückplatte zu­sätzlich auf den innenliegenden Rippen geringerer Höhe 6, 6′ abstützt.The two pistons arranged side by side in the two separate chambers of the container according to Figures 1 and 2 are moved parallel to each other by a push-out plate in the direction of the outlet opening, which engages in the piston wall 4 and is supported at first contact on the ribs of greater height 5, 5 ' . While each piston is pushed forward, the curvature 1 creates a counterpressure on the sealing lip 2, which increases the diameter of the piston at the level of the sealing lip and thereby achieves an optimal seal within the chambers. The pressure can be increased until the ribs of greater height 5, 5 'are compressed and the (not shown) ejection plate is additionally supported on the inner ribs of lower height 6, 6'.

Bei einem vorteilhaften Ausführungsbeispiel, wie es sich in der Praxis bewährt hat, beträgt die Längenabmessung D zwischen den Außenrändern der Dichtungslippe 2 60 mm, die Längenabmessung d des geraden Teils der Kolbenwand 4 58 mm und die Dicke einer der Rippen 5, 6 1,5 mm. Die Wand­stärke a der Kolbenwand 4 kann 2 mm betragen.In an advantageous exemplary embodiment, as has proven itself in practice, the length dimension D between the outer edges of the sealing lip 2 is 60 mm, the length dimension d of the straight part of the piston wall 4 58 mm and the thickness of one of the ribs 5, 6 1.5 mm. The wall thickness a of the piston wall 4 can be 2 mm.

Der Winkel α, unter dem die Außenfläche der Dichtungslip­pe 2 zur senkrechten sich vom Kolbenboden 8 erstreckenden Kolbenwand 4 angeordnet ist, kann zwischen 10 und 30° lie­gen und beträgt vorteilhafterweise 20°.The angle α at which the outer surface of the sealing lip 2 is arranged relative to the vertical piston wall 4 extending from the piston head 8 can be between 10 and 30 ° and is advantageously 20 °.

Figur 3 zeigt einen Schnitt durch einen Behälter für pastöse Massen, der als Zweikomponenten-Kartusche ausgebil­det ist. Mit 9 ist dabei ein zylindrischer Behälter bezeichnet, der durch eine in Längsrichtung angeordnete Trennwand 10 in zwei gleich große symmetrische Kammern 11 unterteilt ist. Die beiden Kammern 11 stehen nicht miteinander in Verbindung; jede Kammer 11 weist an ihrem oberen Ende jeweils eine Auslaßöffnung 12, 13 auf, die unterschiedlichen Durchmesser aufweisen können, wobei die beiden Öffnungen 12, 13 durch die Verlängerung der Trennwand 10 voneinander getrennt sind.Figure 3 shows a section through a container for pasty masses, which is designed as a two-component cartridge. With 9 a cylindrical container is designated, which is divided by a longitudinally arranged partition 10 into two symmetrical chambers 11 of the same size. The two chambers 11 are not connected to one another; each chamber 11 has its each have an outlet opening 12, 13, which can have different diameters, the two openings 12, 13 being separated from one another by the extension of the partition 10.

Die beiden Öffnungen 12, 13 können, wie insbesondere Figur 6 erkennen läßt, in einem Auslaßstutzen 19 mit Außengewinde vorgesehen sein, auf das eine Überwurfmutter 18 aufschraub­bar ist. Die Auslaßöffnungen 12, 13 können gleiche oder unterschiedliche Durchmesser aufweisen, so daß in jedem Fall ein konstantes Mischungsverhältnis der beiden in den getrennten Kammern 11 vorgesehenen Komponenten eingehalten wird.As can be seen in particular in FIG. 6, the two openings 12, 13 can be provided in an outlet connector 19 with an external thread, onto which a union nut 18 can be screwed. The outlet openings 12, 13 can have the same or different diameters, so that in each case a constant mixing ratio of the two components provided in the separate chambers 11 is maintained.

Im Normalbetrieb ist die Zweikomponenten-Kartusche 9, wie die Figuren 3 und 4 zeigen, durch den aufgesetzten Verschlußstöpsel 15 (Figur 5) verschlossen, wobei die beiden Vorsprünge 16, 17 des Verschlußstöpsels 15, deren Durchmesser an den Durchmesser der Auslaßöffnungen 12, 13 angepaßt ist und zwischen denen eine Aussparung 20 vorgesehen ist, auf die Kartusche derart aufgesetzt sind, daß die beiden Vorsprünge 16, 17 in die Auslaßöffnungen 12, 13 eingreifen und diese luftdicht verschließen. Da sie dabei gleichzeitig in die Massen in den Kammern 11 eintauchen und der Verschlußstöpsel 15 durch die Überwurf­mutter 18 festgehalten wird, kann auch nach einem teilwei­sen Entleeren der Kammern 11 mittels der beiden in diesen Figuren nicht dargestellten erfindungsgemäßen Kolben nach Figuren 1 und 2, durch eine ebenfalls nicht dargestellte Ausdrückvorrichtung mit zwei getrennten Ausdrückplatten, diese monatelang aufbewahrt werden, bevor ein weiterer Teil der Komponenten entnommen wird.In normal operation, the two-component cartridge 9, as shown in FIGS. 3 and 4, is closed by the plug 15 (FIG. 5), the two projections 16, 17 of the plug 15, the diameter of which is adapted to the diameter of the outlet openings 12, 13 is and between which a recess 20 is provided, are placed on the cartridge in such a way that the two projections 16, 17 engage in the outlet openings 12, 13 and close them airtight. Since they are simultaneously immersed in the masses in the chambers 11 and the closure plug 15 is held in place by the union nut 18, even after the chambers 11 have been partially emptied by means of the two pistons according to the invention according to FIGS. 1 and 2, not shown in these figures, by a also not shown ejection device with two separate ejection plates, these are kept for months before another part of the components is removed.

Vorteilhafterweise ist der Innenumfang der Überwurfmutter 18 (Figur 7) mit einer ringförmigen sich nach innen erstreckenden Rippe versehen, so daß eine gewisse Klemmwir­kung zwischen Überwurfmutter 18 und Verschlußstöpsel 15 entsteht. Nach dem Lösen der Überwurfmutter 18 wird der Verschlußstöpsel 15 entfernt, wonach durch leichten Druck die Mutter 18 vom Stöpsel 15 getrennt werden kann und eine Mischspitze einsetzbar ist, die zum Gebrauch auf das Außengewinde des Auslaßstutzens 19 aufschraubbar ist.Advantageously, the inner circumference of the union nut 18 (FIG. 7) is annular inward extending rib so that there is a certain clamping effect between the union nut 18 and the plug 15. After loosening the union nut 18, the closure plug 15 is removed, after which the nut 18 can be separated from the plug 15 by light pressure and a mixing tip can be used which can be screwed onto the external thread of the outlet connector 19 for use.

Jede der beiden Kammern 11 ist mit einem erfindungsgemäßen Kolben gemäß den Figuren 1 und 2 versehen, die durch die Ausdrückvorrichtung mit zwei symmetrisch zueinander ange­ordneten Ausdrückplatten, die in die Kammern 11 und in die Kolbenwand eingreifen, gleichzeitig in Richtung der Auslaß­öffnungen 12, 13 gedrückt werden können und demzufolge in einem konstanten Mischungsverhältnis von 50:50 bei gleich großen Auslaßöffnungen bzw. je nach deren Durchmesser in einem anderen beliebig einstellbaren Mischungsverhältnis in Richtung der aufschraubbaren Mischungsspitze die beiden Komponenten befördern.Each of the two chambers 11 is provided with a piston according to the invention as shown in FIGS. 1 and 2, which are simultaneously pressed in the direction of the outlet openings 12, 13 by the ejection device with two ejection plates arranged symmetrically to one another, which engage in the chambers 11 and in the piston wall can and therefore convey the two components in a constant mixing ratio of 50:50 with outlet openings of the same size or, depending on their diameter, in another mixing ratio which can be set as desired in the direction of the screw-on mixing tip.
