Definitions

  • 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.
  • 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.
  • a device 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.
  • 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.
  • 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 .
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the threaded ring 10 is arranged on the aerosol can 3 such that the edge 9 lies in the recess 15.
  • 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.
  • 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.
  • 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.
  • 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.

Abstract

Le dispositif en deux parties est constitué par un anneau fileté (10) comportant un évidement (15) pour la réception des bords (18) du réservoir d'aérosol (3) et par une douille (11), qui peut être encastrée dans l'anneau fileté (10) pour créer une liaison de force et de forme entre l'anneau (10) et le réservoir d'aérosol. Le dispositif est étanché au niveau de la douille (11) par une lèvre d'étanchéité s'appuyant contre une pièce d'adaptation (2). Le dispositif étant tenu à l'extérieur par l'anneau fileté (10) et à l'intérieur par la douille (11) dans la pièce d'adaptation (2), le basculement du réservoir d'aérosol (3) par rapport à la pièce d'adaptation (2) est impossible et l'étanchéité entre la pièce d'adaptation (2) et le réservoir d'aérosol (3) est assurée pendant l'utilisation.
