Aufsteckbare ReinigerflascheDetachable detergent bottle
Beschreibungdescription
Die Erfindung betrifft eine Reinigerflasche aus einem flexiblen Kunststoffmaterial zum Reinigen von Spritz¬ pistolen zum Verarbeiten von Polyurethan-Schaum¬ bildner aus Druckdosen, die einen Verschlußkörper mit einer Austrittsöffnung für das auszubringende Reinigungsmittel aufweist.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.
Polyurethan-Schaumbildner werden vielfach in Druckdo¬ sen ausgeliefert, die zum Anschluß an mit einem An- schlußteil ausgestattete Spritzpistolen geeignet sind. Die an die Spritzpistole über eine Schraub¬ oder Bajonettverbindung angeschlossene Druckdose kann dann bei Betätigung des Pistolenabzuges über die Pi¬ stolenmündung entleert und der Schaum dem dafür vor¬ gesehenen Ort zugeführt werden. Ein innerhalb der Pi¬ stole angeordneter Ventilmechanismus übernimmt dabei die Rolle des Dosenventils und erlaubt eine genaue mengenmäßige und zeitliche Dosierung des Schaumbild¬ ners. Derartige Spritzpistolen sind beispielsweise aus DE-U 87 04 657 und DE-A 38 15 327.0 bekannt.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.
Die üblichen Polyurethan-Schaumbildner haben die Ei¬ genschaft, nach dem Austreten aus der Druckdose unter dem Einfluß von Luftfeuchtigkeit oder aber einer ge¬ sondert zugegebenen zweiten Komponente unter Vernet¬ zung mehr oder weniger rasch auszuhärten. Der ausge¬ härtete Kunststoff führt dazu, daß die Spritzpistole, wenn überhaupt, nur noch unter erheblichem Aufwand gereinigt werden kann. Insbesondere der komplizierte Abzugs- und Ventilmechanismus ist für rück¬ standsbedingte Störungen anfällig. Aus diesem Grunde ist es unbedingt erforderlich, nach Beendigung des Spritzvorgangs die Spritzpistole mit einem auf den Schaumbildner abgestimmten Lösungsmittel zu reinigen. Derartige Reinigungsmittel sind bekannt und werden üblicherweise in Druckdosen ausgeliefert, die ent¬ sprechend den Druckdosen, in denen der Schaumbildner geliefert wird, an die Spritzpistole angeschraubt und über den Auslösemechanismus betätigt werden können.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. In particular, 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.
Derartige Reinigerflaschen haben den Nachteil, daß sie in der Herstellung sehr aufwendig sind, den an Druckdosen gestellten Anforderungen genügen müssen, bei Gebrauch absolut dicht angeschlossen werden müs¬ sen, was bei einem verschmutzten Anschlußmechanismus nicht immer möglich ist, und, bezogen auf die darin enthaltene Menge Reinigungsmittel, recht viel zu be¬ seitigenden Abfall ergeben.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.
Der Erfindung hat daher zum Ziel, eine Reinigerfla¬ sche zu schaffen, die die oben genannten Nachteile vermeidet, insbesondere einfach zu befüllen, zu transportieren, an eine Spritzpistole mit herkömmli¬ chen Anschlußmechanismus anzuschließen und wiederver¬ wendbar ist.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.
Diese Aufgabe wird mit einer Reinigerflasche der Ein¬ gangs bezeichneten Art gelöst, bei der der Ver¬ schlußkörper ein zentral aufgesetztes Anschlußelement mit kreisförmigem Querschnitt und wenigstens einer konzentrisch umlaufenden elastischen Dichtlippe auf¬ weist.This object is achieved with a cleaner bottle of the type described in the introduction, in which the closure body has a centrally placed connecting element with a circular cross section and at least one concentrically circumferential elastic sealing lip.
Mit der erfindungsgemäß gestalteten Reinigerflasche werden die vorstehend genannten Ziele erreicht. Die Flasche ist nicht mehr als Druckflasche ausgebildet, sondern wird nach Aufsetzen auf das Anschlußteil ei¬ ner Spritzpistole durch einfaches Pressen mit der Hand betätigt. Der Anschluß an die Spritzpistole er- folgt über das Anschlußelemen , das dimensionsmäßig an das Anschlußteil einer herkömmlichen Spritzpistole angepaßt ist, wobei eine oder mehrere Dichtlippen da¬ für sorgen, daß das Reinigungsmittel durch die dafür vorgesehene Eintrittsöffnung in das Innere der Spritzpistole gelangt. Durch die Anpassung des An- schlußelements der Reinigerflasche an die Dimensionen des Anschlußteils der Spritzpistole ist sicherge¬ stellt, daß alle die Teile der Spritzpistole, die mit dem Schaumbildner in Berührung kommen, auch mit Rei¬ nigungsmittel benetzt und gespült werden können.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. By adapting the connection element of the cleaner bottle to the dimensions of the connection part of the spray gun, it is ensured that all the parts of the spray gun that come into contact with the foaming agent can also be wetted and rinsed with cleaning agent.
Dimensionsmäßige Anpassung bedeutet, daß das An¬ schlußelement der Reinigerflasche im wesentlichen die Form und Dimensionen des Ventilstamms einer üblichen Druckdose für Polyurethan-Schaumbildner hat.Dimensional adaptation means that the 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.
Um eine adäquate Abdichtung zwischen Reinigerflasche und Spritzpistole zu erzielen, ist es insbesondere zweckmäßig mehrere Dichtlippen, beispielsweise drei oder vier, parallel zueinander vorzusehen. Diese Dichtlippen befinden sich vorzugsweise am der Flasche abgewandten Ende des Anschlußelements und haben - im Längsschnitt - eine sägezahnartige Struktur. Es ver¬ steht sich, daß zumindest die Dichtlippen, vorzugs¬ weise das gesamte Material des Verschlußkörpers, über eine gewisse Elastizität verfügt, die durchaus ge¬ ringer sein kann, als die Elastizität des flexiblen Kunststoffmaterials der Reingerflasche, jedoch aus¬ reichen muß, um die gewünschte Dichtwirkung auch bei kräftiger Betätigung der Flasche herbeizuführen.In order to achieve an adequate seal between the detergent bottle and the spray gun, it is 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.
Zur Verbesserung der Dichtwirkung und insbesondere auch zur Förderung des Sitzes des Anschlußelements im Anschlußteil der Spritzpistole ist es zweckmäßig, den Verschlußkörper mit einem stufenartig ausgebildeten Vorsprung auszustatten, der sich im Bereich des An¬ satzes des Anschlußelements befindet. Dieser Vor- sprung liegt bei angesetzter Reinigungsflasche auf der hohlzylinderisch ausgebildeten Ventilaufnahme des Anschlußteils der Spritzpistole auf. Der Vorsprung ist zweckmäßigerweise in Richtung auf das Anschluße- lement ansteigend ausgebildet.To improve the sealing effect and in particular also to promote 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 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.
Der Verschlußkörper, der erfindungsgemäßen Reiniger¬ flasche ist zweckmäßigerweise als Schraubverschluß ausgebildet, so daß er zum Nachfüllen der Flasche entfernt werden kann. Um eine fabrikmäßig mit Reini¬ gungsflüssigkeit gefüllte Reinigerflasche lagerfähig zu halten und den Inhalt nicht der Verdunstung auszu¬ setzen, ist es ferner zweckmäßig, die Austrittsöff¬ nung mit einer aufextrudierten und abschneidbaren Kappe zu versehen. Ferner ist es zweckmäßig, am Ver¬ schlußkörper über eine flexible Verbindung eine auf¬ steckbare Abdeckhaube vorzusehen, um angebrochene Reinigerflaschen verschließen zu können.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. In order to keep a detergent bottle filled with cleaning liquid in the factory and not to expose the contents to evaporation, it is also expedient to provide the outlet opening with an extruded cap that can be cut off. Furthermore, it is expedient to provide an attachable cover hood on the closure body via a flexible connection, in order to be able to close opened detergent bottles.
Um ein sauberes Abschneiden der vorstehend erwähnten aufextrudierten Kappe zu ermöglichen und insbesondere eine übermäßige oder unzureichende Ablängung des Aus¬ trittkanals zu vermeiden, sollte die Kappe durch eine Nut gegen das Anschlußelement abgesetzt sein, die als Ansatzpunkt für den Schnitt dienen kann.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.
Bevorzugte Flaschengrößen für die erfindungsgemäßen Reinigerflaschen sind solche mit 250 und 500 ml In¬ halt. Bei solchen Größen kann mit der Hand ein opti¬ maler Preßdruck ausgeübt werden.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.

Die in Fig. 1 gezeigte Reinigerflasche 1 besteht aus dem eigentlichen Flaschenkörper 2 und einem darauf aufgesetzten Verschlußkörper 3 in Form eines Schraub¬ verschlusses. Teil des Verschlußkörpers 3 ist das An¬ schlußelement 4 mit kreisförmigem Querschnitt, daß mittig auf den eigentlichen Verschlußkörper 3 aufge¬ setzt ist und aus einem umlaufenden Vorsprung 6 mit stufenförmigen Ausformung aufsteigt. Der umlaufende Vorsprung, der als Dicht- und Zentrierring aufzufas¬ sen ist, hat eine Stufenfläche, die zum Anschlußele¬ ment hin ansteigt.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.
Am oberen Ende des Anschlußelements 4 befindet sich die kanalförmige Austrittsöffnung 5. Am der Reini¬ gungsflasche abgewandten Ende des Anschlußelements 4 befindet sich ein Abfolge konzentrisch umlaufenden Dichtlippen 7, die im Längsschnitt ein sägezahn- artiges Profil ergeben, wie im Detail A dargestellt. Die Dichtlippen bestehen aus dem Material des Ver¬ schlußkörpers, wobei sich versteht, das dieses Mate¬ rial die für die Erzielung der Dichtwirkung notwen¬ dige Elastizität aufweist. Die erwähnte, im Längs¬ schnitt sägezahnartige Struktur weist im dargestell¬ ten Fall mit den waagerechten Flächen der Dichtlippen nach oben; andere Strukturen sind ebenfalls möglich. So können die Dichtlippen beispielsweise oben wie un¬ ten abgeschrägte Flanken aufweisen oder eine waage¬ rechte Fläche auf der Unterseite.The channel-shaped outlet opening 5 is located at the upper end of the connection element 4. At the end of the connection element 4 facing away from the cleaning bottle there is a sequence of concentrically circumferential sealing lips 7, which in longitudinal section result in a sawtooth-like profile, as shown in detail A. 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. For example, the sealing lips can have beveled flanks at the top or a horizontal surface on the underside.
Im dargestellten Fall ist die Austrittöffnung 5, die kanalförmig ausgebildet ist, mit einer aufextru¬ dierten Verschlußkappe 8 versehen. Diese Verschlu߬ kappe 8 muß vor in Gebrauchnahme der Flasche abge¬ schnitten werden, wobei die zwischen Verschlußkappe 8 und Anschlußelement 4 vorgesehene Nut 9 Ansatzpunkt für den Schneidvorgang ist. Auf diese Weise wird si¬ chergestellt, das eine für den Gebrauch der Reini- gungsflasche schmale Länge des Anschlußelements gege¬ ben ist.In the case shown, 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.
Zum Verschließen der einmal geöffneten Reinigungsfla¬ sche dient eine Abdeckhaube 10, die in an und für sich bekannter Weise einem flexiblen Steg mit dem Verschlußkörper 3 verbunden ist.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.
Der Verschlußkörper 3 selbst ist zweckmäßigerweise als Schraubverschluß ausgebildet, der über ein Innen¬ gewinde 12 auf ein entsprechendes Außengewinde am Hals 13 des Flaschenkörpers 2 aufgesetzt ist.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.
