Definitions

  • the present invention relates to paint-spray guns and in particular ones with a top cup.
  • Paint-spray guns are widely used in almost all of the sectors in which it is necessary to paint products of various types (for example, car bodies, furniture, ironmongery, etc.). As is known, these are devices consisting basically of a head provided with: a nozzle for outlet of the paint; a first inlet mouth for connection to a compressor; and a second inlet mouth for connection to the reservoir of the liquid to be sprayed.
  • a trigger or push-button which are also normally inserted in the head
  • the compressor is actuated, which, by blowing in the compressed gas enables outlet of the liquid from the tanks and atomization thereof through the nozzle.
  • two types of paint-spray guns are commonly used: ones with a bottom cup and ones with a top cup.
  • the guns with a top cup offer the advantage of enabling a complete use of the liquid to be sprayed, thus eliminating the problem of the residue, which, instead, always remains in guns with a bottom cup.
  • Spray guns with a top cup present, however, problems of loading of the liquid, and the various solutions suggested, such as for example bags of liquid to be inserted into the cup, or two cups, one inserted inside the other, do not meet completely the requirements of practicality on the part of the operators of the sector.
  • Scope of the invention The purpose of the present invention is to make available a new type of disposable cup for spray guns, in particular ones with a top cup, which will enable all the paint to come out completely and will be easy to use.
  • FIG. 1 shows a cross section of the cup according to the invention
  • - Figure 2 shows the plug-valve; and - Figure 3 shows a detail of the invention (easily perforable surface portion with corresponding projecting edge)
  • the disposable cup 10 is substantially a cup of a traditional type but, as may be seen from Figures 1 and 3, it has at least one easily perforable surface portion 11, which is bounded along its perimeter by a raised edge 12, which projects on the outside of the cup and inside which there is a channel 13 (see Figure 3) perpendicular to the surface of the cup.
  • the position of said channel 13 can be marked by an appropriate indication (such as an arrow, a raised portion, etc.) cut into the surface of the cup in a position corresponding to the channel 13.
  • Said easily perforable surface portion normally consists of the same material that forms the rest of the cup but more thin than the rest of the surface of the cup.
  • said easily perforable surface portion is circular, and consequently the raised edge 12 will also be circular.
  • said at least one easily perforable surface portion is set on the base of the cup (i.e., the part of the cup that, in the working position, faces upwards).
  • Figure 2 shows the plug-valve 14, which, as may be seen, consists of a cap 15, to which solidly adheres a wall 16, shaped so as to be engaged on the edge 12 and hence on the perimeter of the easily perforable surface portion 11.
  • the wall 16 will be shaped like the surface of a right cylinder.
  • Said wall 16 has at least one slit 17, preferably two, arranged in positions that are diametrally opposite to one another.
  • the height of the wall 16 will be such as to enable perforation of the perforable surface 11 once the plug-valve is inserted in the hole formed by the raised edge
  • just one portion 18 of the circular wall 16 will be such as to enable perforation of the surface 11 , whilst the other will be as long as the raised edge 12.
  • the presence of the underlying channel 19 may be marked by an appropriate indication (an arrow possibly coloured, a raised portion, a notch, etc.).
  • the edge of the cap can be knurled in order to facilitate its use by the operator.
  • cup according to the invention is immediately understandable. Once the liquid to be sprayed has been poured into the cup, the operator will apply the gun to the cup, using the usual means of engagement; alternatively, the cup may be already filled and will hence be simply connected to the gun in the usual way.
  • one or more plugs-valves will be applied by perforating the respective surface portions.
  • rotating the plug-valve so as to connect the slit 17 or one of the slits 17 to the channel 13 (and thus also to the possible channel 19), it will be possible to cause the air to pass and hence to paint without any problems, whilst in the resting stages it will be sufficient to rotate the plug-valve, thus excluding the inside of the cup from the outside.
  • the operation of rotation is obviously facilitated if the marks indicating the channel 19 and the channel 13 are present, as explained above.
  • the cup may be thrown away and replaced by a new cup, either pre-charged or not.
  • the cup and the plug-valve may be made of materials normally used for this purpose, for example rigid or semi-rigid plastic suitable for being produced by moulding.
  • the cup may be graduated in order to enable ease of evaluation of the amount of liquid remaining.
