Eine derartige Auspressvorrichtung dient dem Ausbringen von in Gebinden verpackten Massen, wie Mörtel- oder Dichtmassen, an einem Applikationsort. Gebinde umfassen beispielsweise Kartuschen mit einem oder mehreren Aufnahmeräumen für eine oder mehrere Komponenten der auszubringenden Masse, die direkt oder z. B. in Folienbeutel verpackt in den Aufnahmeräumen der Kartusche vorgesehen sind. Der Begriff "Gebinde" umfasst zudem mit einer oder mehreren Komponenten der auszubringenden Masse befüllte Folienbeutel, die in einen separaten oder an der Auspressvorrichtung angeordneten Aufnahmekörper eingesetzt werden.Such a squeezing device serves to dispense packaged masses, such as mortar or sealants, at an application site. Containers include, for example cartridges with one or more receiving spaces for one or more components of the mass to be applied, the direct or z. B. in foil bags are provided in the receiving spaces of the cartridge. The term "container" also includes foil bags filled with one or more components of the mass to be delivered, which are inserted into a separate receiving body or arranged on the ejection device.
Die Auspresseinrichtung der Auspressvorrichtung weist üblicherweise einen Vorschubmechanismus auf, bei dessen Betätigung ein Vorschubmittel, wie beispielsweise eine Kolbenstange über ein vorbestimmtes Mass vorgeschoben wird. Ein an der Kolbenstange angeordnetes Druckübertragungsmittel, wie z. B. ein Kolben wirkt auf die in dem Gebinde befindliche Masse ein, so dass bei jedem Vorschub eine entsprechende Menge der Masse durch eine Ausgabeöffnung ausgebracht wird.The squeezing device of the squeezing device usually has a feed mechanism, upon the actuation of which an advancing means, such as a piston rod, is advanced beyond a predetermined amount. A arranged on the piston rod pressure transmitting means, such. B. a piston acts on the mass located in the container, so that at each feed a corresponding amount of the mass is discharged through a dispensing opening.
Aus der
Nachteilig an der bekannten Lösung ist, dass während dem Auspressvorgang, insbesondere von Mörtel- und Dichtmassen, hohe Kräfte auf die verschwenkbare Frontplatte wirken. Diese Kräfte werden unter anderem über den Schnappverschluss auf die Auspressvorrichtung übertragen. Dabei kann sich das flexible Schnappmittel verformen und der Schnappverschluss sich lösen, so dass die Frontklappe unbeabsichtigt von der geschlossenen Stellung in eine zumindest teilweise offene Stellung verschwenken kann. Dies führt zu Störungen beim Auspressvorgang und stellt für den Anwender einen zusätzlichen Aufwand dar.A disadvantage of the known solution that act during the Auspressvorgang, in particular of mortar and sealants, high forces on the pivotable front panel. Among other things, these forces are transmitted to the squeezing device via the snap lock. In this case, the flexible snap means may deform and the snap closure may loosen, so that the front flap may inadvertently pivot from the closed position to an at least partially open position. This leads to disturbances in the pressing process and represents an additional expense for the user.
Aufgabe der Erfindung ist es, eine Auspressvorrichtung für Massen enthaltende Gebinde mit einer verschwenkbaren Frontplatte zu schaffen, die während des gesamten Auspressvorgangs sicher in der geschlossenen Stellung gehalten ist.The object of the invention is to provide a squeezing device for mass-containing container with a pivotable front panel, which is securely held in the closed position during the entire Auspressvorgangs.
Die Aufgabe ist durch die Merkmale der unabhängigen Ansprüche gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen dargelegt.The object is solved by the features of the independent claims. Advantageous developments are set forth in the subclaims.
Gemäss der Erfindung weist der Schnappverschluss neben dem flexiblen Schnappmittel einen starren Halteabschnitt auf.According to the invention, the snap closure in addition to the flexible snap means on a rigid holding portion.
Mit dem starren Halteabschnitt lassen sich die beim Auspressvorgang auf die Frontklappe wirkenden Kräfte ohne eine wesentliche Verformung des Schnappverschlusses auf die Auspressvorrichtung übertragen. In der Kombination des starren Halteabschnitts mit dem flexiblen Schnappmittel ist die Frontplatte während des gesamten Auspressvorgangs und in verschiedenen Ausrichtungen der Auspressvorrichtung gegen ein unbeabsichtigtes Lösen gesichert. Zudem ist die Frontplatte einfach wieder von der geschlossenen Stellung in die offene Stellung verschwenkbar, da sich der Schnappverschluss mit einem Druck in die entsprechende Verschwenkrichtung öffnen lässt.With the rigid holding section, the forces acting on the front flap during the pressing operation can be transmitted to the squeezing device without any significant deformation of the snap closure. In the combination of the rigid holding portion with the flexible snap means, the face plate is secured against inadvertent loosening during the entire squeezing operation and in different orientations of the squeezing device. In addition, the front panel is easily pivoted again from the closed position to the open position, since the snap closure can be opened with a pressure in the corresponding pivoting direction.
In diesem Zusammenhang wird unter einem starren Halteabschnitt ein Halteabschnitt verstanden, der aus einem Material gefertigt ist, das eine höhere Steifigkeit im Vergleich mit dem Material des flexiblen Schnappmittels aufweist. Vorteilhaft ist der starre Halteabschnitt aus dem gleichen Material wie die Frontplatte gefertigt.In this context, a rigid holding portion is understood to mean a holding portion made of a material having a higher rigidity in comparison with the material of the flexible snap means. The rigid holding section is advantageously made of the same material as the front plate.
Vorzugsweise ragt das flexible Schnappmittel in eine von dem starren Halteabschnitt gebildete Halteausnehmung für eine als Bolzen ausgebildete Schnappaufnahme bereichsweise hinein, wobei das flexible Schnappmittel vorteilhaft den Bolzen hintergreift. Besonders vorteilhaft ist das flexible Schnappmittel am freien Ende einer vorteilhaft U-förmig ausgebildeten Halteausnehmung des starren Halteabschnitts vorgesehen, was ein einfaches Ver- und Entriegeln der verschwenkbaren Frontplatte und sicheres Halten derselben in der geschlossenen Stellung gewährleistet.Preferably, the flexible snap means projects into a retaining recess formed by the rigid holding portion for a snap-action receptacle designed as a bolt, in regions, wherein the flexible snap means advantageously engages behind the bolt. Particularly advantageously, the flexible snap means is provided at the free end of an advantageous U-shaped retaining recess of the rigid holding portion, which ensures a simple locking and unlocking of the pivotable front panel and secure holding the same in the closed position.
Bevorzugt ist das flexible Schnappmittel federnd ausgebildet, was eine einfache Entriegelung der Frontplatte ermöglicht und eine ausreichende Sicherung der Frontplatte zum Halten in der geschlossenen Stellung gewährleistet. Beispielsweise ist das flexible Schnappmittel aus einem Federstahl gefertigt und entsprechend der Ausgestaltung der Schnappaufnahme beziehungsweise der Verriegelung ausgebildet.Preferably, the flexible snap means is resilient, which allows easy unlocking of the front panel and ensures sufficient securing of the front panel for holding in the closed position. For example, the flexible snap means is made of a spring steel and formed according to the configuration of the snap-action receptacle or the latch.
