Description

Push-cleaner bottle

description

The invention relates to a cleaner bottle made of a flexible plastics material for cleaning Spritz¬ guns for processing of polyurethane foam-forming agents from pressurized containers comprising a closure body having an outlet opening for the auszubringende detergent.

Polyurethane foaming agents are often delivered in Druckdo¬ sen, which are suitable for connection to a trailer equipped arrival spray guns. The connected to the spray gun via a bayonet connection or Schraub¬ pressure box can then stolen muzzle emptied on actuation of the trigger on the gun Pi¬ and the foam are for the supplied vor¬ viewed place. A arranged within the Pi¬ stole valve mechanism assumes the role of the can valve and allows precise quantitative and temporal dosage of Schaumbild¬ listeners. Such spray guns are known for example from DE-U 87 04 657 and DE-A 38 15 327.0.

The usual polyurethane foaming agent have the Ei¬ genschaft, after emerging from the pressure cell under the influence of humidity or a ge secretes added second component under Vernet¬ wetting rapidly harden more or less. The ausge¬ hardened plastic causes the spray gun, if any, can be cleaned only with considerable effort. In particular, the complicated trigger and valve mechanism is prone to residue is taken up use disorders. For this reason it is imperative to clean after you stop dispensing the spray gun with a tuned to the foaming solvent. Such cleaning agents are known and are usually delivered in pressurized cans, which can be correspondingly screwed the pressure doses in which the foaming agent is supplied to the spray gun and activated via the triggering mechanism.

Such cleaner bottles have the disadvantage that they are very expensive to produce, have to satisfy the requirements placed on pressure cells, müs¬ be connected completely sealed, in use, sen, which is not always possible in a polluted connection mechanism, and, based on the therein contained amount of detergent, give quite a lot to be¬ side of waste.

The invention therefore aims to provide a specific Reinigerfla¬ that avoids the aforementioned disadvantages, particularly easy to fill, transport to connect with a spray gun with herkömmli¬ chen connection mechanism and wiederver¬ reversible.

This object is achieved with a designated type transfer cleaner bottle Ein¬, wherein said yoke body has a centrally Ver¬ be translated connecting element of circular cross section and at least one concentric circumferential elastic sealing lip auf¬.

With the inventively designed cleaner bottle, the above objectives are achieved. The bottle is no longer designed as a pressure bottle but is to be placed on the connecting part ei¬ ner spray gun operated by simply pressing with the hand. The connection to the spray gun ER- follows on the Anschlußelemen, which is dimensionally adapted to the connection part of a conventional spray gun, wherein one or more sealing lips da¬ for ensure that the cleaning agent passes through the provided entry port into the interior of the spray gun. By adapting the arrival circuit elements of the detergent bottle to the dimensions of the connecting part of the spray gun is sicherge¬ assumes that all the parts of the spray gun, which come into contact with the foaming agent, can be wetted with cleansers on Rei¬ and rinsed.

Dimensional adjustment means that the circuit element An¬ the cleaner bottle has substantially the shape and dimensions of the valve stem of a conventional pressurized can for polyurethane foaming.

In order to achieve an adequate seal between the bottle and the spray gun cleaner, it is particularly expedient multiple sealing lips to provide, for example, three or four, parallel to each other. These sealing lips are preferably located at the bottle end facing away from the connecting element and have - in longitudinal section - a sawtooth-like structure. It is se, whereby that at least the sealing lips, preferred wise all the material of the closure body, has a certain elasticity, which can be quite ge ringer when the elasticity of the flexible plastic material of the Reingerflasche but must aus¬ enough to bring about the desired sealing effect even at stronger actuation of the bottle.

To improve the sealing effect and in particular also for the promotion of the seat of the connection element in the connection part of the spray gun, it is expedient to provide the closure body with a step-like projection which is located in the region of the An¬ set of the connection element. This process is leaps and mixed cleaning bottle on the hohlzylinderisch trained valve receiving the connection part of the spray gun. The projection is expediently designed lement rising toward the Anschluße-.

The closure body Reiniger¬ bottle according to the invention is advantageously designed as a screw, so that it can be removed for refilling of the bottle. In order to maintain a factory-supply fluid-filled with Reini¬ cleaner bottle shelf life and do not expose the content auszu¬ the evaporation, it is also advantageous to provide the Austrittsöff¬ voltage with an extruded-cuttable and cap. Furthermore, it is expedient to provide at Ver¬ path body via a flexible connection auf¬ a plug cover to seal opened cleaner bottles.

To allow a clean cutting of the extruded-on cap mentioned above and in particular to avoid an excessive or inadequate cutting to length of the channel Aus¬ occurs, the cap should be offset by a groove against the connecting element, which can serve as a starting point for cutting.

Preferred bottle sizes for the inventive detergent bottles are those with 250 and 500 ml In¬ halt. In such quantities by hand a opti¬ painter pressing pressure can be exerted.

The invention is further illustrated by the accompanying drawings. Of these shows

Fig. 1 shows an embodiment of the cleaner bottle according to the invention,

Fig. 2 shows a conventional spray gun cleaner bottle aufge¬ translated and Fig. 3 shows the terminal portion of the spray gun of FIG. 2 in an enlarged representation.

The cleaner bottle 1 shown in Fig. 1 consists of the actual bottle body 2 and a body 3 placed thereon closure shutter in the form of a Schraub¬. Part of the closure body 3 is the An¬-circuit element 4 is provided with a circular cross section, that is centrally aufge¬ linked to the closure body 3 and rises from a circumferential projection 6 with step-like shape. The circumferential projection sen aufzufas¬ as a sealing and centering, has increased a step face that ment to Anschlußele¬ out.

At the upper end of the connecting element 4, the channel-shaped outlet opening supply bottle facing away is 5. On the Reini¬ end of the connecting member 4 is a sequence concentrically encircling sealing lips 7, which result in a sawtooth-like profile in the longitudinal section, as shown in detail A. The sealing lips consist path body from the material of the method, it being understood that this Mate¬ rial having for achieving the sealing effect notwen¬ ended elasticity. The above-mentioned, in the longitudinal section in the sawtooth-like structure has dargestell¬ th case with the horizontal surfaces of the sealing lips upwards; other structures are also possible. Thus, the sealing lips may for example comprise as above un¬ th beveled edges or waage¬ right surface on the bottom.

In the illustrated case, the outlet opening 5, which is channel-shaped, is provided with a closure cap aufextru¬-founded. 8 This Verschlu߬ cap 8 has to be cut before abge¬ use in acquisition of the bottle, the closure cap 8 provided between and connecting element 4 Groove 9 is a starting point for the cutting operation. In this way, chergestellt si¬ which is gege¬ ben a supply bottle for the use of cleaning narrow length of the connecting element.
