Definitions

  • the invention first relates to a spray can for spraying spray material, in particular liquids, such as hair fixatives, paints, pharmaceuticals or the like, by means of compressed air via an outlet provided with an arbitrarily actuable and self-closing valve.
  • spray material in particular liquids, such as hair fixatives, paints, pharmaceuticals or the like
  • Spray cans which contain environmentally harmful, often also explosive and comparatively expensive propellant gases. Furthermore, mechanical, usually manually operated, spray air spray cans are known, which, however, are only able to produce a spray jet that is not sufficiently finely atomized and insufficiently continuous for some purposes.
  • Spray systems that work with a motor-driven compressor are too expensive and complex for many areas of application.
  • the object of the invention is to provide a spray can which is able to fully replace the widespread but environmentally harmful propellant spray cans and which ensures fine and uniform atomization of the spray material in a simple, inexpensive construction and with easy handling.
  • a spray can of the type described in the introduction, that the interior of the spray storing the spray material is penetrated by a discharge tube which opens into the outlet and can be connected via an inlet to a compressed air source and which; communicates with the inside of the can via at least one suction opening.
  • This solution according to the invention also allows compressed air to enter the interior of the can via the suction openings, and also to promote the escape of the sprayed material from the interior of the can in a finely divided state which is mixed with the compressed air.
  • a suction tube adjoins the suction opening or each suction opening of the dispensing tube, which extends into the inner can and the wall of which is penetrated by recesses.
  • Such suction tubes are preferably arranged in the region of that end of the dispensing tube which is located below the surface of the spray material during the spraying process.
  • the recesses are expediently to be designed or arranged in such a way that a part of them favors the inflow of compressed air into the interior of the can, another part favors the outflow of the spray material from the interior of the can. It is thereby achieved that this outflow via the dispensing device, e.g. a spray nozzle, done very evenly.
  • suction openings preferably diametrically opposite one another, can be provided within the can interior in the vicinity of the compressed air inlet, to which suction tubes, optionally curved, connect, one of which is connected to the one below and the other extends into the area of the interior of the can located above the suction openings.
  • suction tubes optionally curved, connect
  • the interior of the can can be penetrated by a U-shaped delivery tube, which results in the advantage that both the outlet for the spray material and the inlet for the compressed air are on the same side the spray can can be arranged and, if necessary, can be combined into one unit.
  • the size and number (density) of the recesses in the suction tubes must be adapted to the respective viscosity and density of the sprayed material in order to achieve the desired concentration of the sprayed material in the spray jet.
  • At least some of the recesses in the suction tubes can be fitted with devices, e.g. Valves are provided that allow air and sprayed material to flow through these recesses only in one direction.
  • Exchangeable dispensers equipped with spray nozzles e.g. the delivery tube, possibly flexible, can be connected to extend the delivery tube.
  • a spray can according to the invention can be used as a disposable packaging for the Serve spray material.
  • the interior of the can can be made refillable with spray material, for example via a separate refill opening or after removal of a detachable part of the can wall. In the latter case, occasional cleaning or maintenance of the can or replacement of the spray material is also made possible.
  • the invention also extends to a device suitable for supplying it with compressed air.
  • such a device consists of a preferably flexible connecting line which can be coupled at one end to the automatically closing or closable inlet of at least one spray can and can be connected to a compressed air source at the other end.
  • such a connecting line preferably in a branch connection, can have a pressure relief valve which can be set to a desired pressure value and can contain a shut-off valve which can be actuated arbitrarily by means of a handle in order to control the compressed air supply as required .
  • Such a compressor is comparatively inexpensive, quiet in operation and does not need to have any measuring or control equipment in order to be able to be used in the context of the invention.
  • An important advantage of the spray can according to the invention is therefore that a pressure accumulator can be dispensed with.
  • a pressure reducing valve in the connecting line leading to the compressed air source as a throttle.
  • a part of a spray can according to the invention which receives the outlet and the inlet can accordingly be connected to the spray nozzle and also to the compressed air source via a common connecting piece.
  • Such a connector can form a compact and easy-to-use, solid unit which can be coupled to the part of the spray can which receives the inlet for the compressed air and the outlet for the spray material via seals, preferably in a form-fitting manner, and also the valves for dispensing the spray material and to supply compressed air to the inside of the can.
  • this opens up the further advantageous possibility of controlling the dispensing of the spray material and to actuate the valve serving the supply of compressed air jointly, namely in such a way that the latter can be actuated separately, but in any case together with the valve serving to deliver spray material.
  • FIG. 1 shows an axial section through a spray can according to the invention of a first embodiment
  • FIG. 3 also shows an axial section of a dispensing device which can be connected to the outlet of the spray can if necessary.
  • Fig.4 relates to another embodiment of such
  • a suction tube 8 adjoins each suction opening 7 of the dispensing tube 6, which - curved - extends into the interior 3 of the can and the wall of which is penetrated by recesses 9.
  • a dispensing device which consists of a connection cap 11 and a flexible or rigid extension tube 12 which runs coaxially with the dispensing tube 6.
  • This connecting line 13 is provided in a branch connection 16 with an overpressure valve 17 that can be set to a desired value and contains a shut-off valve 18 that can be actuated with a handle 19.
  • this connecting line 13 can be designed so that it can supply several spray cans together with compressed air.
  • the embodiment of the spray can according to FIG. 4 differs from that according to FIG. 1 in that the interior 3 of the can is penetrated by a U-shaped delivery tube 6, in the apex of which a suction opening 7 is provided.
  • a suction tube (8) connects to this suction opening (7), the recesses (9) of which are located in the region of the base of the spray can.
  • the outlet 4 for the spray material 2 and the inlet 5 for the compressed air receiving part of the spray can is via a common connector according to FIG. 5 both to the spray nozzle 10 and connectable to the compressed air source.
  • This connection piece 20 also carries the valves 21 and 22 for controlling the delivery of spray material 2 and for the inlet of compressed air and can be coupled with the upper part of the spray can in any way.
  • the handling of these valves 21 and 22 are arranged in such a way that the valve 22 serving for the supply of compressed air is separate if necessary, but can be operated together with the valve 21 serving to dispense the sprayed material.
  • valve 21 serving to dispense spray material 2 wants to be opened or closed
  • the valve 22 controlling the supply of compressed air is also opened or closed in exactly synchronous fashion.
  • valve controlling the compressed air supply can be actuated separately in order to make the spray can, if it is initially not under pressure, ready for operation by introducing compressed air.
  • a spray can according to the invention can be used as packaging for storing and transporting the spray material to the consumer "and after emptying it can be separated from the compressed air source and - as disposable packaging - replaced by a filled can.
  • a spray can within the scope of the invention with an additional, sealable refill opening and refill spray material; for this purpose, for example, a detachable part of the can can be made removable by means of a sealable screw or plug connection.
