Definitions

  • the present invention relates to a spray can according to the preamble of claim 1.
  • Such spray cans are used in many fields of application. They can be filled with air-hardening PU foam, paints or other sprayable substances. In any case, the cap offers protection of the valve against dirt as well as against mechanical damage.
  • Spray cans are known which open an outlet opening of the valve by turning and close again after use by rotating this outlet opening. In this sense, spray cans are preferably sealed that contain the PU foam mentioned.
  • caps of these spray cans are freely rotatable, so that they do not remain in a position covering the outlet opening with certainty. Rather, there is a risk that they will be inadvertently rotated and thereby expose the outlet opening, as a result of which the desired protection is no longer provided.
  • the present invention is therefore based on the object of designing a spray can of the generic type in such a way that its overall functionality is improved.
  • the cap remain in a certain position, for example when the cap forms the basis for an additional component which is attached, connected to the valve and rotatable relative to the cap.
  • the invention offers a particularly simple solution for this.
  • the lower edge of the circumferential collar is provided with serrations which dig into a web which is integrally formed on the cap and which bears against the lower edge of the collar when it is placed on the valve disk.
  • the cap is usually made of plastic, while the valve disk is made of metal, the tips of the prongs dig into the softer material of the cap, so that this ensures that the cap is adequately secured against rotation.
  • the collar is provided on the outside with a plurality of spaced-apart, outwardly turned cams which dig into the side wall when the cap is attached and thus also form an anti-rotation device.
  • This type of shaping has the advantage that the already painted surface is not damaged. In addition, the strain on the molds is very low.
  • the cams can be elongated and extend in the longitudinal axis direction of the spray can.
  • a combination of prongs and cams is also conceivable. Also knurling the outside of the collar.
  • the inside of the collar facing the plate dome is provided with cams against which a cap part rests.
  • a particularly firm form-fit results if the collar is provided with cams on the outside and inside.
  • Figure 1 shows two half sections of a partial section of a spray can in a side view.
  • valve plate 1 of a spray can according to the invention which has a circumferential collar 2, on which a cap 3 is placed.
  • the lower edge of the collar 2 is provided with prongs 5 extending over the entire circumference dig into the support web 6 due to the different hardnesses of the collar 2 made of metal and the cap 3 made of plastic.
  • the right-hand half-section shows an embodiment of the collar 2, in which cams 4 are formed all the way round, which extend outwards towards the wall of the cap 3.
  • the cams 4 are web-like and extend in the central axis direction of the valve disk.
  • the cams 4 begin their course directly at the lower edge of the collar, so that a certain sharp-edged design is created in this area, through which a particularly intimate interlocking of the cams 4 with the attached cap 3 is achieved.
  • other suitable shapes are of course also conceivable, for example in the form of protruding holes which have a small, sharp-edged collar all around, which likewise digs into the elastic material of the cap 3.
