Definitions

  • the invention relates to a valve disk for a spray can, with a Tellerdom for receiving a spray valve and a molded to form a circumferential annular groove concentric collar, in which an elastic sealing ring is held positively.
  • valve disks are prefabricated, that is, they are necessarily shaped and equipped with the sealing ring. This assembly is then connected by means of suitable tools with a spray container in which usually a spray liquid is stored, which emerges when operating the spray valve as an aerosol.
  • the seal u.a. is required by an exact position of the sealing ring within the trained annular groove.
  • the invention is therefore the object of further developing a valve disk of the generic type so that a secure locking of the sealing ring while minimizing the manufacturing costs and the use of materials is possible.
  • valve disk having the features of claim 1.
  • a trained in this sense valve plate is initially characterized by its simple and extremely cost-effective production, since the bending of the annular groove bounding outer edge in the direction of the sealing ring or the interior of the annular groove can be done as a simple manufacturing process that can be carried out without significant additional manufacturing time ,
  • the seen in the axial direction of the valve disk support surface on which the sealing ring partially rests, can be achieved by an angling, wherein the outer edge initially parallel to the central axis of the valve disk and is bent in its free end, preferably at right angles, ie in the interior directed the annular groove.
  • the outer edge at least in regions, is bent around at an acute angle, namely over almost the entire height of the outer edge.
  • the outer edge may be provided with recesses, preferably in the form of adjacent triangles, so that the outer edge is serrated.
  • a spray is shown, which is generally designated by the reference numeral 1 and having a spray container 2, with which a Tellerdom-looking valve disk 3 is positively connected, wherein in the connection area a circumferential, elastic sealing ring 7 is arranged through prevents that located in the spray container 2 located under pressure medium can escape.
  • the plate dome not shown as a detail, serves to receive a spray valve 15.
  • the elastic sealing ring 7 consisting for example of a rubber or plastic, is positively held in an annular groove 6, which is formed by molding a collar 5 on the valve plate 3, wherein the collar 5 is concentric.
  • the positive connection of the sealing ring 7 is achieved in that an annular groove 6 delimiting outer edge 8 is at least partially circumferentially bent in the direction of the annular groove 6 to form a support surface 9 for the sealing ring 7.
  • valve disk 3 Since the valve disk 3 is supplied with the inserted sealing ring 7 as a prefabricated structural unit and the spray container 2 is then fitted with it, the sealing ring 7 is held securely until then on the valve disk.
  • the illustrated embodiments all show the valve disk 3 in the mounted position, wherein the sealing ring 7 is supported on a bead 4 of the spray container 2, while a wall 16 of the valve disk 3 is shaped such that it is held in a form-fitting manner on the bead 4.
  • the support surface 9 is bent approximately at right angles to the axially extending outer edge 8 in the rest and abuts the lower outer edge of the sealing ring 7 under its slight deformation.
  • the wall 16 has a circumferential bead 10, which also extends approximately in the amount of the support surface 9 in the direction of the annular groove 6, so that the sealing ring 7 is clamped, so to speak.
  • a bead 11 is additionally pressed into the collar 3 of the example according to FIG. 3, by means of which the sealing ring 7 bears against the beading 4 at higher pressure in the covering area of the bead 11, resulting in a greater tightness.
  • the support surface 9 is formed as embossing edge 12, in which the material thickness is smaller than that of the outer edge 8 in the rest.
  • FIG. 6 shows the support surface 9 is not bent at right angles to the axial extent of the valve disk 3, but at an acute angle, wherein also a certain deformation of the sealing ring 7 takes place.
  • the elastic material of the sealing ring 7 swells partially in these gaps 14, whereby said positive engagement is achieved.
  • the formation of the gaps 14 can be seen as an enlarged view in FIG.
