Abstract

The device made of two parts is comprised of a threaded ring (10) having a recess (15) for receiving the edges (18) of the aerosol can and is also comprised of a sleeve (11) which may be fitted into the threaded ring (10) to create a force- and form-connection between the ring (10) and the aerosol can (3). The device is sealed at the sleeve (11) by a sealing lip bearing against an adapter part (2). Since the device is held on the outer side by means of the threaded ring (10) and on the inner side by means of the sleeve (11) in the adapter part (2), the tipping of the aerosol can (3) with respect to the adapter part (2) is impossible and the tightness between the adapter part (2) and the aerosol can (3) is provided for during its utilization.

Description

Die vorliegende Erfindung betrifft eine Einrichtung zum Verbinden einer Spritzpistole, die mit einem einen hülsenförmigen Ansatz aufweisenden Adapterteil versehen ist, mit einer Aerosoldose mit einem Ventil und mit einem das Ventil umschliessenden Rand, die einen Gewindering hat, der ein zum Gewinde des Adapterteiles passendes Gewinde und eine zur Aufnahme des Randes der Aerosoldose vorgesehene Ausnehmung aufweist, die so ausgebildet ist, dass ein das Loch des Gewinderinges umschliessender zylindrischer Abschnitt gebildet wird, der einen Wulst zum Hintergreifen des Randes aufweist und der so ausgebildet ist, dass mindestens ein Teil desselben durch den Rand der Aerosoldose radial nach innen verformt wird.The present invention relates to a device for connecting a spray gun, which is provided with an adapter part having a sleeve-shaped projection, with an aerosol can with a valve and with an edge surrounding the valve, which has a threaded ring which has a thread matching the thread of the adapter part and has a recess provided for receiving the edge of the aerosol can, which is designed in such a way that a cylindrical section is formed which surrounds the hole of the threaded ring, which has a bead for engaging behind the edge and which is designed such that at least a part of it passes through the edge the aerosol can is deformed radially inwards.

Zum Aufsetzen von Aerosoldosen, die einen das Ventil umschliessenden Rand haben, auf eine Spritzpistole werden Adapter verwendet. Ein derartiger Adapter weist einen Abschnitt, der über den Rand gestülpt wird, und einen konischen Gewindeansatz auf, der in der Spritzpistole einschraubbar ist. Beim Einschrauben des Adapters wird der über den Rand der Aerosoldose gestülpte Abschnitt zusammengezogen und so die Aerosoldose gehalten.Adapters are used to place aerosol cans that have an edge surrounding the valve on a spray gun. Such an adapter has a section that is slipped over the edge and a conical thread attachment that can be screwed into the spray gun. When the adapter is screwed in, the section slipped over the edge of the aerosol can is pulled together and the aerosol can is held in this way.

Es ist auch bekannt, auf den Rand der Aerosoldose einen Gewindering aufzusetzen und diesen in einen Adapterteil für eine Spritzpistole einzuschrauben.It is also known to place a threaded ring on the edge of the aerosol can and screw it into an adapter part for a spray gun.

Aus der US-A-3 756 512 ist eine Einrichtung gemäss dem Oberbegriff des Patentanspruches 1 bekannt, die einen Gewindering enthält, der ein zum Gewinde des Adapterteiles passendes Gewinde und eine zur Aufnahme des Randes der Aerosoldose vorgesehene Ausnehmung aufweist. Durch diese Ausnehmung wird ein das Loch umschliessender, zylindrischer Abschnitt gebildet, der eine Wulst zum Hintergreifen des Randes der Aerosoldose aufweist und der so ausgebildet ist, dass mindestens ein Teil derselben durch den Rand der Aerosoldose radial nach innen verformt wird.From US-A-3 756 512 a device according to the preamble of claim 1 is known which contains a threaded ring which has a thread matching the thread of the adapter part and a recess provided for receiving the edge of the aerosol can. This recess forms a cylindrical section which surrounds the hole and which has a bead for engaging behind the edge of the aerosol can and which is designed such that at least a portion thereof is deformed radially inward by the edge of the aerosol can.

Diese Lösungen haben den Nachteil, dass die Verbindung zwischen Adapter bzw. Gewindering und Aerosoldose nicht kraft- und formschlüssig ist, um die Dichtheit der Verbindung während des Gebrauchs zu gewährleisten.These solutions have the disadvantage that the connection between adapter or threaded ring and aerosol can is not non-positive and positive to ensure the tightness of the connection during use.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung der eingangs genannten Art zu schaffen, bei der durch die kraft- und formschlüssige Verbindung zwischen Aerosoldose und der Einrichtung und zwischen Adapterteil und der Einrichtung einerseits ein Verkippen der Aerosoldose im Adapterteil und andererseits ein Lösen der auf die Aerosoldose aufgedrückten Einrichtung verhindert wird.The invention has for its object to provide a device of the type mentioned, in which the non-positive and positive connection between the aerosol can and the device and between the adapter part and the device on the one hand tilting the aerosol can in the adapter part and on the other hand releasing the Aerosol can pressed device is prevented.

Diese Aufgabe wird erfindungsgemässen dadurch gelöst, dass der Gewindering mit zwei ringförmigen Wülsten versehen ist, die am zylindrischen Abschnitt und der diesem gegenüberliegenden Seitenfläche der stirnseitigen Ausnehmung so ausgebildet sind, dass sie in die Ausnehmung hineinragen zum Hintergreifen des Randes der Aerosoldose, und dass eine Hülse mit einem zum Innendurchmesser des Gewinderinges passenden Aussendurchmesser vorgesehen ist, die von der anderen Stirnseite her in den Gewindering einführbar ist, um den zylindrischen Abschnitt zu stützen, und an einem Ende mit einem Ansatz versehen ist, um ein Durchdrücken der Hülse durch den Gewindering zu verhindern.This object is achieved according to the invention in that the threaded ring is provided with two annular beads which are formed on the cylindrical section and the side face of the front-side recess opposite this, in such a way that they protrude into the recess for engaging behind the edge of the aerosol can, and in that a sleeve is provided with an outer diameter matching the inner diameter of the threaded ring, which can be inserted into the threaded ring from the other end face to support the cylindrical section, and is provided at one end with a projection to prevent the sleeve from being pushed through the threaded ring .

Die mit der Erfindung erreichbaren Vorteile sind im wesentlichen darin zu sehen, dass die Einrichtung eine bessere Dichtung bewirkt zwischen Ventil und Adapterteil, weil neben der zwischen Ventil und Adapterteil gebildeten Dichtungsstelle eine weitere Dichtungsstelle zwischen dem Adapterteil und einem Abschnitt der inneren Umfangsfläche der Hülse gebildet wird, und die Einrichtung billig herstellbar und einfach in der Anwendung ist.The advantages achievable with the invention are essentially to be seen in the fact that the device brings about a better seal between the valve and the adapter part, because in addition to the sealing point formed between the valve and the adapter part, a further sealing point is formed between the adapter part and a section of the inner peripheral surface of the sleeve , and the device is inexpensive to manufacture and easy to use.

Weitere Vorteile ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels der Erfindung anhand der beiliegenden Zeichnungen, wobei

  • Figur 1 eine im Halbschnitt dargestellte Ansicht einer mit einer Spritzpistole über einen Adapterteil und ein Ausführungsbeispiel der Verbindungseinrichtung verbundene Aerosoldose und
  • Figur 2 einen Schnitt durch die in Figur 1 verwendete Verbindungseinrichtung darstellt.
Further advantages result from the following description of an embodiment of the invention with reference to the accompanying drawings, wherein
  • 1 shows a view in half section of an aerosol can connected to a spray gun via an adapter part and an exemplary embodiment of the connecting device, and
  • Figure 2 shows a section through the connecting device used in Figure 1.

Wie Figur 1 zeigt, ist eine Spritzpistole 1 über einen Adapterteil 2 und eine Verbindungseinrichtung mit einer Aerosoldose 3 mit einem Ventil 4 verbunden. Der als einstückiger Körper ausgebildete Adapterteil 2 weist zwei Abschnitte 5, 6, die jerweils mit einem Innengewinde versehen sind, auf. Somit kann der Adapterteil 2 einerseits über eine Gewindehülse 7 mit der Spritzpistole 1 und andererseits kann die Aerosoldose 3 über die Verbindungseinrichtung mit dem Adapterteil 2 verschraubt werden. Der Adapterteil 2 weist ferner einen hülsenartigen Ansatz 8 auf, durch den das Ventil 4 hindurchragt.As FIG. 1 shows, a spray gun 1 is connected to a valve 4 via an adapter part 2 and a connecting device with an aerosol can 3. The adapter part 2, which is designed as a one-piece body, has two sections 5, 6, which are each provided with an internal thread. Thus, the adapter part 2 can be screwed to the spray gun 1 on the one hand via a threaded sleeve 7 and, on the other hand, the aerosol can 3 can be screwed to the adapter part 2 via the connecting device. The adapter part 2 also has a sleeve-like extension 8 through which the valve 4 projects.

Wie Figur 2 zeigt, ist die Verbindungseinrichtung zweiteilig ausgebildet und besteht aus einem Gewindering 10 und einer Hülse 11. Der Gewindering 10 und die Hülse 11 bestehen beispielsweise aus Kunststoff.As FIG. 2 shows, the connecting device is constructed in two parts and consists of a threaded ring 10 and a sleeve 11. The threaded ring 10 and the sleeve 11 are made of plastic, for example.

Der Gewindering 10 hat ein zum Innengewinde passendes Aussengewinde 12. An einer Seite ist ein Ansatz 13 zum Aufsetzen der nicht dargestellten Verschlusskappe für die Aerosoldose ausgebildet. Der Gewindering 10 hat eine Ausnehmung 15, die koaxial zum Loch 16 in der Stirnseite so ausgebildet ist, dass ein elastisch verformbarer, zylindrischer Abschnitt 17 gebildet wird. Der zylindrische Abschnitt 17 ist so ausgestaltet, dass das freie Ende über die Stirnfläche des Gewinderinges 10 hinausragt.The threaded ring 10 has an external thread 12 that matches the internal thread. On one side, an extension 13 is formed for fitting the closure cap (not shown) for the aerosol can. The threaded ring 10 has a recess 15 which is formed coaxially to the hole 16 in the end face in such a way that an elastically deformable, cylindrical section 17 is formed. The cylindrical section 17 is designed such that the free end projects beyond the end face of the threaded ring 10.

Wie Fig. 1 zeigt, ist der Gewindering 10 so an der Aerosoldose 3 angeordnet, dass der Rand 9 in der Ausnehmung 15 liegt. Um eine im wesentlichen formschlüssige Verbindung zwischen dem Rand 9 und dem Gewindering 10 zu erzeugen, ist der Gewindering 10 mit zwei ringförmigen Wülsten 18, 19 versehen, die am zylindrischen Abschnitt 17 und der diesem gegenüberliegenden Seitenfläche der Ausnehmung 15 so ausgebildet sind, dass sie in die Ausnehmung 15 hineinragen, und der zylindrische Abschnitt 17 ist so ausgebildet, dass mindestens ein Teil desselben durch den Rand 9 der Aerosoldose 3 radial nach innen verformt wird. Durch die in das Loch 16 eingepresste Hülse 11 wird der elastisch verformte Teil des zylindrischen Abschnittes 17 radial nach aussen gegen den Rand 9 der Aerosoldose 3 gepresst, wodurch die Wülste 18, 19 den Rand 9 hintergreifen. Durch diese Verbindung wird die Einrichtung verdrehsicher an der Aerosoldose befestigt.As shown in FIG. 1, the threaded ring 10 is arranged on the aerosol can 3 such that the edge 9 lies in the recess 15. In order to produce a substantially positive connection between the edge 9 and the threaded ring 10, the threaded ring 10 is provided with two annular beads 18, 19 which are formed on the cylindrical section 17 and the side surface of the recess 15 opposite it so that they are in the recess 15 protrude, and the cylindrical portion 17 is formed such that at least a part thereof is deformed radially inward by the edge 9 of the aerosol can 3. Due to the sleeve 11 pressed into the hole 16, the elastically deformed part of the cylindrical section 17 becomes radially outward against the edge 9 of the aerosol can 3 pressed, whereby the beads 18, 19 engage behind the edge 9. With this connection, the device is secured against rotation on the aerosol can.

Der Hülse 11 ist ein Flansch 20 angeformt, der an eine im Gewindering 10 ausgebildete Schulter 21 anliegt, um ein Durchdrücken der Hülse 11 durch den Gewindering 10 zu verhindern. Am äusseren Umfang der Hülse 11 sind zwei zueinander beabstandete Wülste 22, 23 ausgebildet, die mit im Loch 16 des Gewinderinges 10 ausgebildeten Rillen 24, 25 in Eingriff bringbar sind, um die Hülse 11 im Gewindering 10 zu arretieren. An dem den Flansch 20 aufweisenden Ende der Hülse 11 ist ein von der inneren Umfangsfläche abstehender Abschnitt 27 ausgebildet und eine im wesentlichen V-förmige Rille 26 vorgesehen, die in der Stirnfläche so ausgebildet ist, dass eine Seitenfläche der Rille 26 koaxial zur inneren Umfangsfläche ist. Durch diese Ausbildung entsteht eine L-förmige Dichtungslippe, die mit dem hülsenförmigen Ansatz 8 zusammenwirkt.A flange 20 is formed on the sleeve 11, which abuts a shoulder 21 formed in the threaded ring 10 in order to prevent the sleeve 11 from being pushed through by the threaded ring 10. On the outer circumference of the sleeve 11, two mutually spaced beads 22, 23 are formed, which can be brought into engagement with grooves 24, 25 formed in the hole 16 of the threaded ring 10 in order to lock the sleeve 11 in the threaded ring 10. At the end of the sleeve 11 having the flange 20, a portion 27 projecting from the inner circumferential surface is formed and a substantially V-shaped groove 26 is provided, which is formed in the end surface such that a side surface of the groove 26 is coaxial with the inner circumferential surface . This design creates an L-shaped sealing lip which interacts with the sleeve-shaped extension 8.

Um eine sichere Abdichtung zu gewährleisten, kann der hülsenförmige Ansatz 8 aussen leicht konisch so ausgebildet sein, dass dieser sich zum freien Ende hin verjüngt oder im unteren Bereich einen konischen Abschnitt aufweisen. Dadurch wird erreicht, dass beim Einschrauben der Aerosoldose 3, die L-förmige Dichtungslippe verformt wird. Bei eingeschraubter Aerosoldose 3 bildet diese Dichtungslippe neben der zwischen Ventil und hülsenförmigen Ansatz 8 des Adapterteiles 2 gebildeten Dichtungsstelle eine weitere Dichtungsstelle zwischen der Hülse 11 und dem hülsenförmigen Ansatz 8 des Adapterteiles 2, wodurch verhindert wird, dass zu spritzendes Material zwischen Adapterteil 2 und Aerosoldose 3 heraustreten kann.In order to ensure a secure seal, the sleeve-shaped extension 8 can be slightly conical on the outside so that it tapers towards the free end or has a conical section in the lower region. This ensures that when the aerosol can 3 is screwed in, the L-shaped sealing lip is deformed. When the aerosol can 3 is screwed in, this sealing lip forms, in addition to the sealing point formed between the valve and the sleeve-shaped extension 8 of the adapter part 2, a further sealing point between the sleeve 11 and the sleeve-shaped extension 8 of the adapter part 2, which prevents material to be sprayed between the adapter part 2 and the aerosol can 3 can come out.

Da die Einrichtung einerseits durch den Gewindering 10 am Umfang und andererseits durch die Hülse 11 im Bereich der Dichtungslippe an der Innenseite, d.h. an zwei beabstandeten Stellen im Adapterteil 2 gehalten wird, wird ein Verkippten der Aerosoldose 3 im Adapterteil 2 verhindert und somit die Dichtung zwischen Adapterteil 2 und Aerosoldose 3 während der Anwendung aufrechterhalten.Since the device on the one hand by the threaded ring 10 on the circumference and on the other hand by the sleeve 11 in the region of the sealing lip on the inside, i.e. is held at two spaced locations in the adapter part 2, a tilting of the aerosol can 3 in the adapter part 2 is prevented and thus the seal between the adapter part 2 and aerosol can 3 is maintained during use.
