  • Lever elements are attached to the jaws for manual operation of the crusher.
  • the manageability of the device is to be improved in such a way that precise metering of the substance and emptying of the tube are possible even with a relatively low expenditure of force.
  • an apparatus for forcing a substance out of a deformable tube which has a housing with a base end, an upper portion opposite the base end and side wall portions between the base ends and the upper portion.
  • the device also has a squeezer that can be introduced into the housing, the squeezer having a carrier element and two opposing jaws for gripping and pressing a substance out of the tube.
  • the housing further has an opening in the upper portion through which a dispensing outlet of the tube can be passed, and openings on opposite parts of the side wall portions, by means of which the jaws can be actuated, the jaws being fastened at one end to the carrier element and the crusher also having a manual lever element on at least one jaw.
  • the lever element is connected to the jaw in a connection region in an arrangement in which pressure applied manually to the lever element causes a force on the jaw towards the other jaw.
  • the lever element has a body with reinforcing ribs, the reinforcing ribs being at least partially surrounded by a closed outer skin, a region of the outer skin forming a grip area.
  • a device is provided with the aid of which a user can express a substance from the deformable tube by exerting pressure on the manual lever elements in the grip areas. This pressure is transmitted from the lever element to the jaws and from these to the deformable tube.
  • the device has the advantage that the lever element is particularly well suited to transferring a relatively small force particularly effectively to the deformable tube.
  • the lever element is not designed to be completely solid and therefore rigid, but rather has a certain flexibility due to the reinforcing ribs without losing any of its resilience.
  • the reinforcement ribs are not exposed in the grip area, but are covered by a closed outer skin. This significantly improves the handling of the device, since rib-like structures exposed in the grip area can be pressed into the user's fingers when the device is being handled. This is at least uncomfortable, but can also be painful and impair the handling of the device.
  • the lever element has a concave section on the at least one jaw at the level of the connecting area. This has the task of further improving the manageability of the device.

  • grip ribs are arranged on the outer skin of the lever element in the grip area.
  • the grip ribs can be formed, for example, as relatively low elevations of at most 1 mm on the outer skin and in particular can be arranged transversely to the longitudinal direction of the lever element. The task of the grip ribs is to prevent the user's fingers from slipping off, thereby further improving manageability.
  • the grip ribs can, for example, be made from the material of the outer skin and be formed in one piece with it.
  • connection area between the lever element and the jaw has a length L, L being less than 25% of the length of the jaw. A length measurement in the longitudinal direction of the lever element or the jaw is assumed.
  • length L for example, 2 mm L 20 mm, in particular 3 mm L 12 mm.
  • connection between the lever element and the jaw with these dimensions is robust and stable enough to safely transfer to the jaws a force exerted by the user on the lever element.

  • the connection area is arranged in an upper half of the jaw facing away from the carrier element, but not in the area of the top 20% of the jaw.
  • connection area directs the force exerted by a user and distributes it over the entire length of the jaw. If the connection area is arranged too close to the opening of the housing and thus too close to an outlet of the tube, on the one hand there may be problems in handling because the tube is not sufficiently flexible in the immediate vicinity of its outlet. On the other hand, emptying the tube completely can be problematic.
  • connection area is too far away from the opening in the housing and thus from the outlet of the tube, the lever force achieved on the jaw is significantly less and it is no longer possible to handle the device with low forces.
  • the body of the lever element is formed in one piece with the jaws. This has the advantage that the lever element and the jaws can be designed to be particularly flexible and at the same time stable.
  • the housing is open at its base end and the crusher can be introduced into the housing through its open end and can be fixed therein. In this way, a secure connection between the housing and the crusher can be achieved.
  • Figure 1 shows an empty housing 1 of a device for pressing a substance out of a deformable tube according to an embodiment of the invention.
  • the housing 1 has an open base end 2 and an upper section 3 opposite the base end 2 as well as side wall sections 4 which form the housing 1 between the base end 2 and the upper section 3.
  • the open base end 2 is an in Figure 1
  • the squeezer not shown, can be inserted with a tube. An outlet of the tube can be guided through an opening 5 in the upper section 3.
  • the housing 1 has an opening 8 in each of its side wall sections 4 on two opposite sides. Below the openings 8, the side wall sections 4 protrude outwards and form shoulders 9, so that the open base end is not round in cross section, but also has projections.
  • Figure 2 shows the entire device for pressing a substance out of a deformable tube with the housing 1 according to Figure 1 , a squeezer 10 that can be inserted into the housing 1 and has a tube 24, an application nozzle 30 that can be placed on the housing 1, and a closure cap 40 that can be placed on the application nozzle 30.
  • the squeezer 10 which is described in detail in Figures 3 to 5 is shown, with the tube 24 inserted therein, is passed through the open base end 2 of the housing 1 so that a discharge outlet of the tube 24 is passed through the opening 5 and into the Figures 3 to 5
  • Lever elements of the squeezer 10 shown in more detail are exposed in the openings 8 or protrude through the openings 8 to the outside.
  • the Figures 3 to 5 show the squeezer 10 in cross section and in a side view.

  • the connecting region 20 extends in the longitudinal direction of the jaw 12 or the lever element 15 and, in the embodiment shown, is arranged essentially in the third quarter of the jaw 12, seen from the carrier element 11, more precisely: in the upper half of the Jaw 12, but not in the area of the uppermost 20% of the jaw 12. This achieves a very good leverage effect, which enables the tube to be squeezed out precisely and with relatively little effort and at the same time allows the tube to be emptied well.
  • the force to be used to squeeze out the tube is typically in the range between 18 and 28 N, in particular between 20 and 25 N.
  • the connecting area 20 extends only over a maximum of a quarter of the length of the jaws 12, so that the jaws 12 remain flexible. A high degree of flexibility of the jaws 12 is also achieved in that the extension of the connecting area 20 in the transverse direction is at most half the width of the jaws 12. In the embodiment shown, the connecting area 20 is 6.8 mm wide at its widest point.
  • the lever element 15 has a body 16 with reinforcing ribs 17. These have the effect that the lever element 15 is sufficiently stable despite a non-massive design. A massive design of the lever element 15 would lead to a lack of flexibility and thus to a more difficult handling of the device.
  • the reinforcing ribs 17 can, as in FIGS Figures 3a to 3c shown, be formed transversely to the longitudinal direction of the lever element 15. However, they can also run differently and / or reinforcement ribs 17 extending in several directions or curved reinforcing ribs 17 can be provided.
  • the reinforcement ribs 17 are not exposed on the surface of the lever element 15, at least in a grip area 19 of the lever element 15, but are surrounded or covered by an outer skin 18. A user of the device thus does not come into contact with exposed reinforcing ribs 17 when using the device in the intended manner.
  • the outer skin 18 can surround the lever element 15 completely or only in certain areas. In the embodiment shown, the reinforcing ribs 17 lie as in FIG Figure 4 is visible, laterally free from the grip area 19 and are not encased there by the outer skin 18.
  • the lever element 15 has, at the level of the connecting area 20, a concave section 21 in which the grip area 19 is concave in order to offer a finger a better grip.
  • Figure 3a shows the squeezer 10 in a first position, also referred to as the rest position, in which no force is exerted on the lever elements 15.
  • the jaws 12 are wide open.
  • Figure 3b shows the crusher 10 in a second position, which represents an intermediate position, and which is assumed when a certain force is exerted on the lever elements 15 and thus the jaws 12 by the fact that a user presses the lever elements 15 together with his fingers.
  • this intermediate position the jaws 12 still gape clearly at their upper end 14, but are already touching one another in the lower third. It can be seen that the jaws 12 are not simply pressed together by exerting force on the lever elements 15 but that they are each bent in the process.
  • the arrangement and configuration of the connecting area 20 enables the jaws 12 to be bent and thereby enables the tube to be emptied particularly well from below.
  • FIG. 10 shows the crusher 10 in a third position in which the jaws 12 are fully in contact with each other and which is assumed when starting from fig Figure 3b force continues to be exerted on the lever elements 15.
  • FIGS. 3a to 3c show the squeezer 10 without the tube inserted therein.
  • the jaws 12 can no longer touch one another. Instead of contact, there is a close approach with a strongly squeezed tube arranged in between.
  • connection area 20 between the jaw 12 and the lever element 15, not shown in this view. It can be seen that the connection area 20 has its maximum width v in the area of its upper end. Here v is at most half the width b of the jaw 12 in this area.
  • Figure 5 shows a side view of the squeezer 10.
  • Gripping ribs 22 can be seen therein, which are arranged in the grip area 19 on the outer skin 18 and which are intended to prevent the fingers from slipping off during use.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Herausdrücken eines Stoffes aus einer verformbaren Tube. Die Tube kann beispielsweise aus Kunststoff oder Metall bestehen. Bei dem herauszudrückenden Stoff kann es sich insbesondere um einen Klebstoff handeln.The present invention relates to a device for pressing a substance out of a deformable tube. The tube can for example consist of plastic or metal. The substance to be pressed out can in particular be an adhesive.

Derartige Vorrichtungen zum Herausdrücken eines Stoffes aus einer verformbaren Tube sollen die Handhabung der Tube und das Herausdrücken und Auftragen des Stoffes auf eine Oberfläche erleichtern. Insbesondere soll die Dosierung des Stoffes erleichtert werden.Such devices for pressing a substance out of a deformable tube are intended to facilitate the handling of the tube and the pressing out and application of the substance to a surface. In particular, the dosage of the substance should be made easier.

Aus der EP 24 90 956 B1 ist eine Vorrichtung zum Herausdrücken eines Stoffes aus einer verformbaren Tube bekannt, die ein Gehäuse und einen in das Gehäuse einführbaren Quetscher aufweist, wobei der Quetscher ein Trägerelement und zwei einander gegenüberliegende Backen zum Greifen und Auspressen eines Stoffes aus der Tube aufweist. An den Backen sind Hebelelemente angebracht für eine manuelle Betätigung des Quetschers.From the EP 24 90 956 B1 a device for pressing a substance out of a deformable tube is known which has a housing and a squeezer which can be inserted into the housing, the squeezer having a support element and two opposing jaws for gripping and pressing a substance out of the tube. Lever elements are attached to the jaws for manual operation of the crusher.

Weitere Vorrichtungen zum Herausdrücken eines Stoffes aus einer verformbaren Tube zeigen die CN203186657U und die WO00/00405A2 .Further devices for pressing a substance out of a deformable tube show CN203186657U and the WO00 / 00405A2 .

Es ist eine Aufgabe der vorliegenden Erfindung, eine verbesserte Vorrichtung zum Herausdrücken eines Stoffes aus einer verformbaren Tube anzugeben. Insbesondere soll die Handhabbarkeit der Vorrichtung dahingehend verbessert werden, dass auch mit einem verhältnismäßig geringen Kraftaufwand eine genaue Dosierung des Stoffes und eine Leerung der Tube möglich sind.It is an object of the present invention to provide an improved device for forcing a substance out of a deformable tube. In particular, the manageability of the device is to be improved in such a way that precise metering of the substance and emptying of the tube are possible even with a relatively low expenditure of force.

Diese Aufgabe wird gelöst durch den Gegenstand des unabhängigen Patentanspruchs. Weitere Ausführungsformen sind Gegenstand der Unteransprüche.This object is achieved by the subject matter of the independent patent claim. Further embodiments are the subject of the subclaims.

Gemäß der Erfindung wird eine Vorrichtung zum Herausdrücken eines Stoffes aus einer verformbaren Tube angegeben, die ein Gehäuse mit einem Basisende, einen oberen Abschnitt gegenüber dem Basisende und Seitenwandabschnitte zwischen den Basisenden und dem oberen Abschnitt aufweist. Ferner weist die Vorrichtung einen in das Gehäuse einführbaren Quetscher auf, wobei der Quetscher ein Trägerelement und zwei einander gegenüberliegende Backen zum Greifen und Auspressen eines Stoffes aus der Tube aufweist.According to the invention there is provided an apparatus for forcing a substance out of a deformable tube which has a housing with a base end, an upper portion opposite the base end and side wall portions between the base ends and the upper portion. The device also has a squeezer that can be introduced into the housing, the squeezer having a carrier element and two opposing jaws for gripping and pressing a substance out of the tube.

Das Gehäuse weist ferner eine Öffnung im oberen Abschnitt auf, durch die ein Ausgabeauslass der Tube geführt werden kann, und Öffnungen an gegenüberliegenden Teilen der Seitenwandabschnitte, mittels derer sich die Backen betätigen lassen, wobei die Backen an einem Ende am Trägerelement befestigt sind und der Quetscher darüber hinaus ein manuelles Hebelelement an zumindest einer Backe aufweist.The housing further has an opening in the upper portion through which a dispensing outlet of the tube can be passed, and openings on opposite parts of the side wall portions, by means of which the jaws can be actuated, the jaws being fastened at one end to the carrier element and the crusher also having a manual lever element on at least one jaw.

Das Hebelelement ist in einem Verbindungsbereich mit der Backe in einer Anordnung verbunden, in der ein manuell auf das Hebelelement angewendeter Druck eine Kraft auf die Backe in Richtung auf die andere Backe zu bewirkt. Das Hebelelement weist einen Körper mit Verstärkungsrippen auf, wobei die Verstärkungsrippen zumindest teilweise von einer geschlossenen Außenhaut umgeben sind, wobei ein Bereich der Außenhaut einen Griffbereich ausbildet.The lever element is connected to the jaw in a connection region in an arrangement in which pressure applied manually to the lever element causes a force on the jaw towards the other jaw. The lever element has a body with reinforcing ribs, the reinforcing ribs being at least partially surrounded by a closed outer skin, a region of the outer skin forming a grip area.

Es wird eine Vorrichtung bereitgestellt, mit Hilfe der ein Benutzer einen Stoff aus der verformbaren Tube ausdrücken kann, indem er in den Griffbereichen Druck auf die manuellen Hebelelemente ausübt. Dieser Druck wird von dem Hebelelement auf die Backen und von diesen auf die verformbare Tube übertragen.A device is provided with the aid of which a user can express a substance from the deformable tube by exerting pressure on the manual lever elements in the grip areas. This pressure is transmitted from the lever element to the jaws and from these to the deformable tube.

Die Vorrichtung hat den Vorteil, dass das Hebelelement besonders gut geeignet ist, eine verhältnismäßig geringe Kraft besonders wirksam auf die verformbare Tube zu übertragen. Dazu ist das Hebelelement nicht vollständig massiv und damit steif ausgebildet, sondern es weist aufgrund der Verstärkungsrippen eine gewisse Flexibilität auf, ohne an Belastbarkeit zu verlieren. Dabei liegen die Verstärkungsrippen im Griffbereich nicht frei, sondern sind von einer geschlossenen Außenhaut bedeckt. Dies verbessert die Handhabbarkeit der Vorrichtung wesentlich, da im Griffbereich freiliegende rippenartige Strukturen sich bei der Handhabung der Vorrichtung in die Finger des Benutzers eindrücken können. Dies ist zumindest unangenehm, kann jedoch auch schmerzhaft sein und die Handhabbarkeit der Vorrichtung beeinträchtigen.The device has the advantage that the lever element is particularly well suited to transferring a relatively small force particularly effectively to the deformable tube. For this purpose, the lever element is not designed to be completely solid and therefore rigid, but rather has a certain flexibility due to the reinforcing ribs without losing any of its resilience. The reinforcement ribs are not exposed in the grip area, but are covered by a closed outer skin. This significantly improves the handling of the device, since rib-like structures exposed in the grip area can be pressed into the user's fingers when the device is being handled. This is at least uncomfortable, but can also be painful and impair the handling of the device.

Gemäß einer Ausführungsform der Erfindung weist das Hebelelement an der zumindest einen Backe auf Höhe des Verbindungsbereiches einen konkaven Abschnitt auf. Dieser hat die Aufgabe, die Handhabbarkeit der Vorrichtung weiter zu verbessern. Er bewirkt einen sicheren Halt für die Finger eines Benutzers und verhindert, dass diese bei der Ausübung von Druck abrutschen. Zudem hebt der konkave Abschnitt den Griffbereich optisch hervor.According to one embodiment of the invention, the lever element has a concave section on the at least one jaw at the level of the connecting area. This has the task of further improving the manageability of the device. It provides a secure hold for a user's fingers and prevents them from slipping off when pressure is applied. In addition, the concave section visually emphasizes the grip area.

Im Übrigen kann das Hebelelement beispielsweise konvex ausgebildet sein.Otherwise, the lever element can be convex, for example.

Gemäß einer Ausführungsform der Erfindung gilt für einen Krümmungsradius r der Außenhaut des Hebelelements in dem konkaven Abschnitt 5 mm ≤ r ≤ 50 mm, insbesondere 16 mm ≤ r ≤ 35 mm. Wie sich herausgestellt hat, bietet ein derart gekrümmter Abschnitt einen besonders sicheren Halt im Griffbereich.According to one embodiment of the invention, for a radius of curvature r of the outer skin of the lever element in the concave section 5 mm r 50 mm, in particular 16 mm r 35 mm. As has been found, such a curved section offers a particularly secure hold in the grip area.

Gemäß einer Ausführungsform der Erfindung sind im Griffbereich Griffrippen auf der Außenhaut des Hebelelements angeordnet. Die Griffrippen können beispielsweise als verhältnismäßig niedrige Erhebungen von höchstens 1 mm auf der Außenhaut gebildet sein und insbesondere quer zur Längsrichtung des Hebelelements angeordnet sein. Die Griffrippen haben die Aufgabe, ein Abrutschen der Finger eines Benutzers zu verhindern und dadurch die Handhabbarkeit weiter zu verbessern.According to one embodiment of the invention, grip ribs are arranged on the outer skin of the lever element in the grip area. The grip ribs can be formed, for example, as relatively low elevations of at most 1 mm on the outer skin and in particular can be arranged transversely to the longitudinal direction of the lever element. The task of the grip ribs is to prevent the user's fingers from slipping off, thereby further improving manageability.

Die Griffrippen können beispielsweise aus dem Material der Außenhaut und einstückig mit dieser ausgebildet sein.The grip ribs can, for example, be made from the material of the outer skin and be formed in one piece with it.

Gemäß einer Ausführungsform der Erfindung weist der Verbindungsbereich zwischen dem Hebelelement und der Backe eine Länge L auf, wobei L weniger als 25% der Länge der Backe beträgt. Dabei wird eine Längenmessung in Längsrichtung des Hebelelements bzw. der Backe angenommen.According to one embodiment of the invention, the connection area between the lever element and the jaw has a length L, L being less than 25% of the length of the jaw. A length measurement in the longitudinal direction of the lever element or the jaw is assumed.

Für die Länge L gilt beispielsweise 2 mm ≤ L ≤ 20 mm, insbesondere 3 mm ≤ L ≤ 12 mm.For the length L, for example, 2 mm L 20 mm, in particular 3 mm L 12 mm.

Wie sich herausgestellt hat, ist die Verbindung zwischen Hebelelement und Backe bei diesen Abmessungen robust und stabil genug, um eine durch den Benutzer auf das Hebelelement ausgeübte Kraft sicher auf die Backen zu übertragen. Sie ist jedoch auch verhältnismäßig flexibel und erleichtert somit die Handhabung der Vorrichtung.As has been found, the connection between the lever element and the jaw with these dimensions is robust and stable enough to safely transfer to the jaws a force exerted by the user on the lever element. However, it is also relatively flexible and thus facilitates the handling of the device.

Erfindungsgemäß weist der Verbindungsbereich zwischen dem Hebelelement und der Backe eine maximale Breite v auf, die höchstens die Hälfte einer Breite b der Backe in diesem Bereich beträgt. Beispielsweise kann v höchstens 7 mm betragen.According to the invention, the connection area between the lever element and the jaw has a maximum width v which is at most half a width b of the jaw in this area. For example, v can be at most 7 mm.

Ferner ist es zusätzlich vorteilhaft, wenn der Verbindungsbereich zwischen dem Hebelelement und der Backe im Wesentlichen im dritten Viertel der Backe vom Trägerelement aus gesehen angeordnet ist. Somit ist in einer Ausführungsform der Vorrichtung der Verbindungsbereich in einer von dem Trägerelement abgewandten, oberen Hälfte der Backe angeordnet, nicht jedoch im Bereich der obersten 20% der Backe.Furthermore, it is additionally advantageous if the connection area between the lever element and the jaw is arranged essentially in the third quarter of the jaw as seen from the carrier element. Thus, in one embodiment of the device, the connection area is arranged in an upper half of the jaw facing away from the carrier element, but not in the area of the top 20% of the jaw.

Mit dieser Anordnung lässt sich eine optimale Hebelwirkung erzielen. Der Verbindungsbereich leitet die durch einen Benutzer ausgeübte Kraft und verteilt sie über die gesamte Länge der Backe. Falls der Verbindungsbereich zu nah an der Öffnung des Gehäuses und damit zu nah an einem Auslass der Tube angeordnet ist, kann es einerseits zu Problemen in der Handhabung kommen, weil die Tube in unmittelbarer Nähe ihres Auslasses nicht ausreichend flexibel ist. Zum anderen kann eine vollständige Entleerung der Tube problematisch sein.An optimal leverage effect can be achieved with this arrangement. The connection area directs the force exerted by a user and distributes it over the entire length of the jaw. If the connection area is arranged too close to the opening of the housing and thus too close to an outlet of the tube, on the one hand there may be problems in handling because the tube is not sufficiently flexible in the immediate vicinity of its outlet. On the other hand, emptying the tube completely can be problematic.

Falls wiederum der Verbindungsbereich zu weit entfernt von der Öffnung im Gehäuse und somit vom Auslass der Tube angeordnet ist, ist die erzielte Hebelkraft auf die Backe deutlich geringer und es ist nicht mehr möglich, die Vorrichtung mit geringen Kräften zu handhaben.If, in turn, the connection area is too far away from the opening in the housing and thus from the outlet of the tube, the lever force achieved on the jaw is significantly less and it is no longer possible to handle the device with low forces.

Gemäß einer Ausführungsform ist der Körper des Hebelelements einstückig mit den Backen ausgebildet. Das hat den Vorteil, dass das Hebelelement und die Backen besonders flexibel und gleichzeitig stabil ausgebildet sein können.According to one embodiment, the body of the lever element is formed in one piece with the jaws. This has the advantage that the lever element and the jaws can be designed to be particularly flexible and at the same time stable.

Gemäß einer Ausführungsform ist das Gehäuse an seinem Basisende offen und der Quetscher ist in das Gehäuse durch dessen offenes Ende einführbar und in diesem fixierbar. Auf diese Weise kann eine sichere Verbindung zwischen dem Gehäuse und dem Quetscher erzielt werden.According to one embodiment, the housing is open at its base end and the crusher can be introduced into the housing through its open end and can be fixed therein. In this way, a secure connection between the housing and the crusher can be achieved.

Figur 1 zeigt ein leeres Gehäuse 1 einer Vorrichtung zum Herausdrücken eines Stoffes aus einer verformbaren Tube gemäß einer Ausführungsform der Erfindung. Das Gehäuse 1 weist ein offenes Basisende 2 auf und einen oberen Abschnitt 3 gegenüber dem Basisende 2 sowie Seitenwandabschnitte 4, die zwischen dem Basisende 2 und dem oberen Abschnitt 3 das Gehäuse 1 bilden. Durch das offene Basisende 2 ist ein in Figur 1 nicht gezeigter Quetscher mit einer Tube einführbar. Durch eine Öffnung 5 im oberen Abschnitt 3 kann ein Ausgabeauslass der Tube geführt werden. Figure 1 shows an empty housing 1 of a device for pressing a substance out of a deformable tube according to an embodiment of the invention. The housing 1 has an open base end 2 and an upper section 3 opposite the base end 2 as well as side wall sections 4 which form the housing 1 between the base end 2 and the upper section 3. The open base end 2 is an in Figure 1 The squeezer, not shown, can be inserted with a tube. An outlet of the tube can be guided through an opening 5 in the upper section 3.

Ferner weist das Gehäuse 1 auf zwei gegenüberliegenden Seiten in seinen Seitenwandabschnitten 4 jeweils eine Öffnung 8 auf. Unterhalb der Öffnungen 8 kragen die Seitenwandabschnitte 4 nach außen und bilden Schultern 9, so dass das offene Basisende im Querschnitt nicht rund ist, sondern ebenfalls Auskragungen aufweist.Furthermore, the housing 1 has an opening 8 in each of its side wall sections 4 on two opposite sides. Below the openings 8, the side wall sections 4 protrude outwards and form shoulders 9, so that the open base end is not round in cross section, but also has projections.

Figur 2 zeigt die gesamte Vorrichtung zum Herausdrücken eines Stoffes aus einer verformbaren Tube mit dem Gehäuse 1 gemäß Figur 1, einem in das Gehäuse 1 einsetzbaren Quetscher 10 mit einer Tube 24, einer auf das Gehäuse 1 aufsetzbaren Auftragsdüse 30 und einer auf die Auftragsdüse 30 aufsetzbaren Verschlusskappe 40. Figure 2 shows the entire device for pressing a substance out of a deformable tube with the housing 1 according to Figure 1 , a squeezer 10 that can be inserted into the housing 1 and has a tube 24, an application nozzle 30 that can be placed on the housing 1, and a closure cap 40 that can be placed on the application nozzle 30.

Der Quetscher 10, der im Detail in den Figuren 3 bis 5 gezeigt ist, wird mit der darin eingesetzten Tube 24 durch das offene Basisende 2 des Gehäuses 1 geführt, so dass ein Ausgabeauslass der Tube 24 durch die Öffnung 5 geführt wird und in den Figuren 3 bis 5 näher gezeigte Hebelelemente des Quetschers 10 in den Öffnungen 8 freiliegen bzw. durch die Öffnungen 8 nach außen ragen.The squeezer 10, which is described in detail in Figures 3 to 5 is shown, with the tube 24 inserted therein, is passed through the open base end 2 of the housing 1 so that a discharge outlet of the tube 24 is passed through the opening 5 and into the Figures 3 to 5 Lever elements of the squeezer 10 shown in more detail are exposed in the openings 8 or protrude through the openings 8 to the outside.

Die Figuren 3 bis 5 zeigen den Quetscher 10 im Querschnitt bzw. in einer Seitenansicht. Der Quetscher 10 weist zwei einander gegenüberliegende Backen 12 auf, die zangenartig zusammenwirken und an ihrem unteren Ende 13 mit einem Trägerelement 11 verbunden sind. Wenn der Quetscher 10 in das Gehäuse 1 eingesetzt ist, bildet das Trägerelement 11 einen Boden des Gehäuses 1 aus.The Figures 3 to 5 show the squeezer 10 in cross section and in a side view. The crusher 10 has two opposing jaws 12 which cooperate like pliers and are connected at their lower end 13 to a carrier element 11. When the squeezer 10 is inserted into the housing 1, the carrier element 11 forms a base of the housing 1.

An ihrem oberen Ende 14 klaffen die Backen 12 im Ruhezustand auseinander. Dies ist in Figur 3a gezeigt. Zwischen den Backen 12 ist eine Tube, beispielsweise eine Klebstofftube, derart anordenbar, dass die Backen 12 an der Tubenaußenwand anliegen.At their upper end 14, the jaws 12 gape apart in the resting state. This is in Figure 3a shown. A tube, for example an adhesive tube, can be arranged between the jaws 12 in such a way that the jaws 12 rest against the outer wall of the tube.

Jede Backe 12 weist ein manuelles, das heißt durch einen Benutzer von Hand betätigbares, Hebelelement 15 auf. Das Hebelelement 15 ist jeweils in einem Verbindungsbereich 20 mit der Backe 12 verbunden. Es kann beispielsweise als Spritzgussteil einstückig mit der Backe 12 hergestellt sein. Der Verbindungsbereich 20 erstreckt sich in Längsrichtung der Backe 12 bzw. des Hebelelements 15 und ist in der gezeigten Ausführungsform vom Trägerelement 11 aus gesehen im Wesentlichen im dritten Viertel der Backe 12 angeordnet, genauer gesagt: in der von dem Trägerelement 11 abgewandten, oberen Hälfte der Backe 12, nicht jedoch im Bereich der obersten 20% der Backe 12. Dadurch wird eine sehr gute Hebelwirkung erzielt, die ein Ausdrücken der Tube präzise und mit verhältnismäßig wenig Kraftaufwand und gleichzeitig eine gute Restentleerung der Tube ermöglicht. Die zum Ausdrücken der Tube aufzuwendende Kraft liegt dabei typischerweise im Bereich zwischen 18 und 28 N, insbesondere zwischen 20 und 25 N.Each jaw 12 has a manual lever element 15, that is to say which can be actuated manually by a user. The lever element 15 is connected to the jaw 12 in a connection area 20. It can, for example, be manufactured in one piece with the jaw 12 as an injection-molded part. The connecting region 20 extends in the longitudinal direction of the jaw 12 or the lever element 15 and, in the embodiment shown, is arranged essentially in the third quarter of the jaw 12, seen from the carrier element 11, more precisely: in the upper half of the Jaw 12, but not in the area of the uppermost 20% of the jaw 12. This achieves a very good leverage effect, which enables the tube to be squeezed out precisely and with relatively little effort and at the same time allows the tube to be emptied well. The force to be used to squeeze out the tube is typically in the range between 18 and 28 N, in particular between 20 and 25 N.

Zudem erstreckt sich der Verbindungsbereich 20 lediglich über höchstens ein Viertel der Länge der Backen 12, so dass die Backen 12 flexibel bleiben. Eine hohe Flexibilität der Backen 12 wird auch dadurch erreicht, dass die Ausdehnung des Verbindungsbereichs 20 in Querrichtung höchstens die Hälfte der Breite der Backen 12 beträgt. In der gezeigten Ausführungsform ist der Verbindungsbereich 20 an seiner breitesten Stelle 6,8mm breit.In addition, the connecting area 20 extends only over a maximum of a quarter of the length of the jaws 12, so that the jaws 12 remain flexible. A high degree of flexibility of the jaws 12 is also achieved in that the extension of the connecting area 20 in the transverse direction is at most half the width of the jaws 12. In the embodiment shown, the connecting area 20 is 6.8 mm wide at its widest point.

Das Hebelelement 15 weist einen Körper 16 mit Verstärkungsrippen 17 auf. Diese bewirken, dass das Hebelelement 15 trotz einer nicht massiven Ausbildung ausreichend stabil ist. Eine massive Ausbildung des Hebelelements 15 würde zu einer mangelnden Flexibilität und damit zu einer schwierigeren Handhabung der Vorrichtung führen. Die Verstärkungsrippen 17 können, wie in den Figuren 3a bis 3c gezeigt, quer zur Längsrichtung des Hebelelements 15 ausgebildet sein. Sie können jedoch auch anders verlaufen und/oder es können Verstärkungsrippen 17 mit Verlauf in mehreren Richtungen oder gebogene Verstärkungsrippen 17 vorgesehen sein.The lever element 15 has a body 16 with reinforcing ribs 17. These have the effect that the lever element 15 is sufficiently stable despite a non-massive design. A massive design of the lever element 15 would lead to a lack of flexibility and thus to a more difficult handling of the device. The reinforcing ribs 17 can, as in FIGS Figures 3a to 3c shown, be formed transversely to the longitudinal direction of the lever element 15. However, they can also run differently and / or reinforcement ribs 17 extending in several directions or curved reinforcing ribs 17 can be provided.

Die Verstärkungsrippen 17 liegen zumindest in einem Griffbereich 19 des Hebelelements 15 nicht an der Oberfläche des Hebelelements 15 frei, sondern sind von einer Außenhaut 18 umgeben bzw. überdeckt. Ein Benutzer der Vorrichtung kommt somit nicht mit freiliegenden Verstärkungsrippen 17 in Berührung, wenn er die Vorrichtung in der vorgesehenen Weise benutzt. Die Außenhaut 18 kann das Hebelelement 15 vollständig oder nur in bestimmten Bereichen umgeben. In der gezeigten Ausführungsform liegen die Verstärkungsrippen 17, wie in Figur 4 sichtbar ist, seitlich von dem Griffbereich 19 frei und sind dort nicht von der Außenhaut 18 umhüllt.The reinforcement ribs 17 are not exposed on the surface of the lever element 15, at least in a grip area 19 of the lever element 15, but are surrounded or covered by an outer skin 18. A user of the device thus does not come into contact with exposed reinforcing ribs 17 when using the device in the intended manner. The outer skin 18 can surround the lever element 15 completely or only in certain areas. In the embodiment shown, the reinforcing ribs 17 lie as in FIG Figure 4 is visible, laterally free from the grip area 19 and are not encased there by the outer skin 18.

Das Hebelelement 15 weist auf Höhe des Verbindungsbereiches 20 einen konkaven Abschnitt 21 auf, in dem der Griffbereich 19 konkav geformt ist, um einem Finger einen besseren Halt zu bieten.The lever element 15 has, at the level of the connecting area 20, a concave section 21 in which the grip area 19 is concave in order to offer a finger a better grip.

Anhand der Figuren 3a bis 3c wird die Funktionsweise des Quetschers beim Ausdrücken einer in den Figuren der Übersichtlichkeit halber nicht gezeigten Tube erläutert.Based on Figures 3a to 3c explains how the squeezer works when a tube is not shown in the figures for the sake of clarity.

Figur 3a zeigt den Quetscher 10 in einer ersten Stellung, auch als Ruhestellung bezeichnet, in der keine Kraft auf die Hebelelemente 15 ausgeübt wird. Die Backen 12 sind weit geöffnet. Figure 3a shows the squeezer 10 in a first position, also referred to as the rest position, in which no force is exerted on the lever elements 15. The jaws 12 are wide open.

Figur 3b zeigt den Quetscher 10 in einer zweiten Stellung, die eine Zwischenstellung darstellt, und die eingenommen wird, wenn eine gewisse Kraft auf die Hebelelemente 15 und damit die Backen 12 dadurch ausgeübt wird, dass ein Benutzer mit seinen Fingern die Hebelelemente 15 zusammendrückt. In dieser Zwischenstellung klaffen die Backen 12 an ihrem oberen Ende 14 noch deutlich auseinander, berühren einander im unteren Drittel jedoch bereits. Dabei ist erkennbar, dass die Backen 12 durch Ausübung von Kraft auf die Hebelelemente 15 nicht einfach nur zusammengedrückt werden, sondern dass sie dabei jeweils in sich gebogen werden. Insbesondere die Anordnung und Ausgestaltung des Verbindungsbereichs 20 ermöglicht ein Biegen der Backen 12 und dadurch eine besonders gute Entleerung der Tube von unten her. Figure 3b shows the crusher 10 in a second position, which represents an intermediate position, and which is assumed when a certain force is exerted on the lever elements 15 and thus the jaws 12 by the fact that a user presses the lever elements 15 together with his fingers. In this intermediate position, the jaws 12 still gape clearly at their upper end 14, but are already touching one another in the lower third. It can be seen that the jaws 12 are not simply pressed together by exerting force on the lever elements 15 but that they are each bent in the process. In particular, the arrangement and configuration of the connecting area 20 enables the jaws 12 to be bent and thereby enables the tube to be emptied particularly well from below.

Figur 3c zeigt den Quetscher 10 in einer dritten Stellung, bei der die Backen 12 vollständig in Kontakt miteinander sind und die eingenommen wird, wenn ausgehend von Figur 3b weiterhin Kraft auf die Hebelelemente 15 ausgeübt wird. Figure 3c Fig. 10 shows the crusher 10 in a third position in which the jaws 12 are fully in contact with each other and which is assumed when starting from fig Figure 3b force continues to be exerted on the lever elements 15.

Die Figuren 3a bis 3c zeigen den Quetscher 10 ohne darin eingesetzte Tube. Wenn eine Tube zwischen den Backen 12 angeordnet ist, können die Backen 12 einander nicht mehr berühren. An die Stelle einer Berührung tritt dann eine nahe Annäherung mit dazwischen angeordneter, stark gequetschter Tube.The Figures 3a to 3c show the squeezer 10 without the tube inserted therein. When a tube is arranged between the jaws 12, the jaws 12 can no longer touch one another. Instead of contact, there is a close approach with a strongly squeezed tube arranged in between.

Figur 4 zeigt den Verbindungsbereich 20 zwischen der Backe 12 und dem in dieser Ansicht nicht gezeigten Hebelelement 15. Dabei ist erkennbar, dass der Verbindungsbereich 20 seine maximale Breite v im Bereich seines oberen Endes aufweist. Dabei beträgt v höchstens die Hälfte der Breite b der Backe 12 in diesem Bereich. Figure 4 shows the connection area 20 between the jaw 12 and the lever element 15, not shown in this view. It can be seen that the connection area 20 has its maximum width v in the area of its upper end. Here v is at most half the width b of the jaw 12 in this area.

Figur 5 zeigt eine Seitenansicht des Quetschers 10. Darin sind Griffrippen 22 erkennbar, die im Griffbereich 19 auf der Außenhaut 18 angeordnet sind und die ein Abrutschen der Finger bei der Benutzung verhindern sollen. Die Griffrippen 22 können beispielsweise als Ausformungen der Außenhaut 18 selbst ausgebildet sein. Figure 5 shows a side view of the squeezer 10. Gripping ribs 22 can be seen therein, which are arranged in the grip area 19 on the outer skin 18 and which are intended to prevent the fingers from slipping off during use. The grip ribs 22 can, for example, be designed as moldings of the outer skin 18 itself.
