Definitions

  • the invention relates to a cleaner bottle made of a flexible plastic material for cleaning spray guns for processing polyurethane foaming agents from pressure cans, which has a closure body with an outlet opening for the detergent to be dispensed.
  • Polyurethane foaming agents are often supplied in pressure sockets which are suitable for connection to spray guns equipped with a connecting part.
  • the pressure can connected to the spray gun by means of a screw or bayonet connection can then be emptied when the gun trigger is actuated via the gun mouth and the foam can be fed to the location provided for this purpose.
  • a valve mechanism arranged inside the spray gun takes over the role of the can valve and permits precise quantitative and temporal metering of the foaming agent.
  • Such spray guns are known for example from DE-U 87 04 657 and DE-A 38 15 327.0.
  • the usual polyurethane foaming agents have the property of hardening more or less quickly after they emerge from the pressure can under the influence of atmospheric humidity or else a separately added second component with crosslinking.
  • the hardened plastic means that the spray gun can only be cleaned, if at all, with considerable effort.
  • the complicated trigger and valve mechanism is susceptible to residues due to residues. For this reason it is absolutely necessary to clean the spray gun with a solvent that is suitable for the foaming agent after the end of the spraying process.
  • Such cleaning agents are known and are usually supplied in pressure cans which, according to the pressure cans in which the foaming agent is supplied, can be screwed onto the spray gun and actuated via the trigger mechanism.
  • Detergent bottles of this type have the disadvantage that they are very complex to produce, must meet the requirements placed on pressure cans, must be connected absolutely tight when in use, which is not always possible with a dirty connection mechanism, and, based on the contained therein Amount of detergent, quite a lot of waste to be removed.
  • the aim of the invention is therefore to create a cleaner bottle which avoids the disadvantages mentioned above, in particular is easy to fill, to transport, to connect to a spray gun with a conventional connection mechanism and is reusable.
  • the above-mentioned goals are achieved with the detergent bottle designed according to the invention.
  • the bottle is no longer designed as a pressure bottle, but is actuated by simply pressing it by hand after it has been placed on the connecting part of a spray gun.
  • the connection to the spray gun follows via the connecting element, which is dimensionally adapted to the connecting part of a conventional spray gun, one or more sealing lips ensuring that the cleaning agent reaches the interior of the spray gun through the inlet opening provided therefor.
  • connection element of the cleaner bottle essentially has the shape and dimensions of the valve stem of a conventional pressure cell for polyurethane foaming agents.
  • sealing lips are particularly expedient to provide a plurality of sealing lips, for example three or four, parallel to one another.
  • These sealing lips are preferably located at the end of the connecting element facing away from the bottle and have a sawtooth-like structure in longitudinal section. It goes without saying that at least the sealing lips, preferably the entire material of the closure body, have a certain elasticity, which may well be less than the elasticity of the flexible plastic material of the cleaning bottle, but must be sufficient to achieve the desired sealing effect even when the bottle is pressed vigorously.
  • the closure body with a step-like projection which is located in the region of the attachment of the connection element. This pre jump is when the cleaning bottle is attached to the hollow cylindrical valve seat of the connecting part of the spray gun.
  • the projection is expediently designed to rise in the direction of the connecting element.
  • the closure body, the cleaning bottle according to the invention is expediently designed as a screw cap, so that it can be removed for refilling the bottle.
  • the cap In order to enable the above-mentioned extruded cap to be cut cleanly and in particular to avoid excessive or inadequate cutting of the outlet channel, the cap should be offset against the connecting element by a groove which can serve as a starting point for the cut.
  • Preferred bottle sizes for the cleaning bottles according to the invention are those with 250 and 500 ml content. In such sizes, an optimal pressure can be exerted by hand.
  • FIG. 1 shows an embodiment of the cleaner bottle according to the invention
  • FIG. 2 shows a conventional spray gun with attached detergent bottle and Fig. 3 shows the connection part of the spray gun of Fig. 2 in an enlarged view.
  • the cleaning bottle 1 shown in FIG. 1 consists of the actual bottle body 2 and a closure body 3 placed thereon in the form of a screw closure.
  • Part of the closure body 3 is the connection element 4 with a circular cross-section, which is placed centrally on the actual closure body 3 and rises from a circumferential projection 6 with a stepped shape.
  • the circumferential projection which is to be regarded as a sealing and centering ring, has a step surface that rises towards the connecting element.
  • the channel-shaped outlet opening 5 is located at the upper end of the connection element 4.
  • the sealing lips consist of the material of the closure body, it being understood that this material has the elasticity necessary for achieving the sealing effect.
  • the mentioned sawtooth-like structure in the longitudinal section points in the illustrated case with the horizontal surfaces of the sealing lips upwards; other structures are also possible.
  • the sealing lips can have beveled flanks at the top or a horizontal surface on the underside.
  • the outlet opening 5, which is channel-shaped, is provided with an extruded closure cap 8.
  • This closure cap 8 must be cut off before the bottle is put into use, the between the closure cap 8 and connecting element 4 provided groove 9 is the starting point for the cutting process. In this way it is ensured that the connecting element has a narrow length for the use of the cleaning bottle.
  • a cover 10 is used to close the opened cleaning bottle, which is connected in a manner known per se to a flexible web with the closure body 3.
  • the closure body 3 itself is expediently designed as a screw closure, which is placed over an internal thread 12 on a corresponding external thread on the neck 13 of the bottle body 2.
  • FIG. 2 shows a conventional spray gun 15 with a detergent bottle 1 placed thereon, the bottle body 2 being shown broken off.
  • the cleaning bottle 1 is inserted with the connecting element 4 of the closure body 3 into the connecting part 16 of the spray gun, the connecting element 4 being partially inside the connecting part 16.
  • FIG. 3 shows an enlargement of the connecting part 16 from FIG. 2 in a longitudinal section.
  • the pressurized can containing prepolymer can be screwed into an outer receptacle 17 with an internal thread 18 for operating the spray gun.
  • An inner receptacle 19 concentrically surrounds a cavity 20 into which the valve of the pressurized can containing prepolymer protrudes.
  • This receiving part 19, which gives the cavity 20 concentrically and also receives the connecting element 4 of the cleaning bottle according to the invention, the projection 6 resting on the upper side 21 of the receiving part 19 and the sealing lips 7 of the connecting element 4 abutting the inner wall 22.
  • a ball valve 23 arranged underneath can be pulled over the trigger of the spray gun.
  • Stole 15 are actuated so that the valve mechanism opens and prepolymer or cleaning fluid can be pressed into the interior of the spray gun.
  • the detergent bottle 1 has not yet been fully inserted into the receiving part 19; with complete insertion in the direction of arrow B, the concentric projection 6 rests on the upper side 21 of the receiving part 19.
