Description

Fließbecher für eine Farbspritzpistole Flow cup for a paint spray gun
Die Erfindung betrifft einen Fließbecher für eine Farbspritzpistole nach dem Oberbegriff des Anspruchs 1.The invention relates to a flow cup for a paint spray gun according to the preamble of claim 1.
Ein solcher Fließbecher ist aus dem Stand der Technik bekannt, beispielsweise aus der WO 98/32539. Dieser Fließbecher ist für den einmaligen Gebrauch vorgesehen und umfasst einen Behälter aus Kunststoff und einen darauf aufsetzbaren Deckel zum Verschließen des Behälters. An der Deckeloberseite sind Anschlussmittel zum Aufsetzen und Befestigen des Fließbechers auf eine Farbspritzpistole oder einem auf dieser befestigten Adapter vorgesehen. Der Fließbecher wird hierbei "upside- down", also mit der Deckelseite nach unten auf die Farbspritzpistole aufgesetzt. Die in dem Fließbecher befindliche Farbe fließt dann aufgrund der Schwerkraft nach unten in den Farbeiniaufkanal der Farbspritzpistole. Um den schwerkraftgetriebenen Fluss der Farbe zu ermöglichen, ist ein Druckausgleich zwischen dem Innern des Farbbechers und der Umgebung erforderlich. Um diesen Druckausgleich zu gewährleisten, ist im Behälterboden eine Belüftungsöffnung eingebracht, welche mittels eines Klebstreifens oder eines manuell betätigbaren Ventils verschließbar ist.Such a flow cup is known from the prior art, for example from WO 98/32539. This flow cup is intended for single use and comprises a plastic container and a lid that can be placed on it to close the container. On the top of the cover, connection means for placing and attaching the flow cup to a paint spray gun or an adapter fastened thereon are provided. The gravity cup is placed "upside-down" on the paint spray gun with the lid side down. The paint in the flow cup then flows downward into the paint inlet channel of the paint spray gun due to gravity. In order to allow the gravity-driven flow of paint, a pressure equalization between the interior of the paint cup and the environment is required. To ensure this pressure equalization, a ventilation opening is made in the bottom of the container, which can be closed by means of an adhesive strip or a manually operable valve.
Sämtliche aus dem Stand der Technik bislang bekannten Einrichtungen zum Verschließen der Belüftungsöffnung haben sich bezüglich der Dichtigkeit als unzureichend erwiesen. Auch bei einem Ventilmechanismus kann nicht zuverlässig ausgeschlossen werden, dass beim Abstellen des mit Farbe gefüllten Farbbechers auf dessen Boden Farbe durch die Belüftungsöffnung austritt.All of the devices known so far from the prior art for closing the ventilation opening have proven to be inadequate in terms of tightness. Even in the case of a valve mechanism, it cannot be reliably ruled out that when the ink cup filled with ink is placed on the floor, ink will escape through the ventilation opening.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, den aus dem Stand der Technik bekannten Fließbecher nach dem Oberbegriff des Anspruchs 1 so weiterzubilden, dass ein Ausfließen von Farbe durch die Belüftungsöffnung zuverlässig vermieden wird.Proceeding from this, the object of the invention is to further develop the flow cup known from the prior art according to the preamble of claim 1 in such a way that the outflow of paint through the ventilation opening is reliably avoided.
Gelöst wird diese Aufgabe mit einem Fließbecher mit den Merkmalen des Anspruchs 1. Vorteilhafte Ausführungsbeispiele dieses Fließbechers sind den Unteransprüchen zu entnehmen.This object is achieved with a flow cup with the features of claim 1. Advantageous exemplary embodiments of this flow cup can be found in the subclaims.

Wie in Figur 1 gezeigt, umfasst der erfindungsgemäße Fließbecher einen becherförmigen Behälter 1 und einen darauf über ein Gewinde 19 aufschraubbaren Deckel 2. Das am oberen Rand des Behälters 1 angeformte Gewinde 19 zum Aufschrauben des Deckels 2 ist in Figur 2 erkennbar. Der Deckel 2 weist an seiner Oberseite einen Auslassstutzen 20 mit einer in Figur 1 nicht dargestellten Auslassöffnung 19 auf. An der Außenseite des Auslassstutzen 20 ist ein Anschlussteil 3 angeformt. Das Anschlussteil 3 dient zum Aufsetzen und zum Befestigen des Fließbechers auf eine Farbspritzpistole oder auf einem zwischen der Farbspritzpistole und dem Fließbecher angeordneten Adapter. In dem in den Figuren dargestellten Ausführungsbeispiel umfasst das Anschlussteil 3 ein Gewinde 21 und eine keilförmige Nut 22, welche mit korrespondierenden Anschlussteilen der Farbspritzpistole, nämlich einem entsprechenden Innengewinde und einem Zapfen zum Eingreifen in die Nut 22, zusammenwirken. Der Behälter 1 ist becherförmig mit einem kreisrunden Behälterboden 23 und einer vom Behälterboden aus sich nach oben leicht konisch erweiternden Seitenwand 24 ausgebildet, wie aus Figur 2 ersichtlich.As shown in FIG. 1, the flow cup according to the invention comprises a cup-shaped container 1 and a cover 2 that can be screwed onto it by means of a thread 19. The thread 19 formed on the upper edge of the container 1 for screwing on the cover 2 can be seen in FIG. The lid 2 has on its upper side an outlet connector 20 with an outlet opening 19, not shown in FIG. 1. A connection part 3 is formed on the outside of the outlet connection 20. The connecting part 3 is used to place and fasten the flow cup on a paint spray gun or on an adapter arranged between the paint spray gun and the flow cup. In the exemplary embodiment shown in the figures, the connecting part 3 comprises a thread 21 and a wedge-shaped groove 22 which cooperate with corresponding connecting parts of the paint spray gun, namely a corresponding internal thread and a pin for engaging in the groove 22. The container 1 is cup-shaped with a circular container base 23 and a side wall 24 which widens slightly conically upwards from the container base, as can be seen from FIG.
In der Figur 5 ist der Fließbecher in einer Seitenansicht dargestellt, wobei der Behälter 1 im Schnitt gezeigt ist. In der Detailansicht X von Figur 5 ist der zentrale Bereich des Behälterbodens 23 gezeigt. Am Behälterboden 23 ist ein hohlzylindrischer Vorsprung 10 ausgebildet, dessen Wandung 29 vom Behälterboden 23 senkrecht nach außen vorsteht. Der Vorsprung 10 ist einstückig mit dem Behälterboden 23 verbunden. Die Mittelachse A des hohlzylindrischen Vorsprungs 10 ist konzentrisch zur Mittelachse des Behälters 1 angeordnet. Ebenfalls konzentrisch zu dieser Achse A ist eine Belüftungsöffnung 4 im Behälterboden 23 eingebracht. Die Belüftungsöffnung 4 wird von einer ringförmigen Wandung 8 umschlossen. An der Außenseite 9 der Wandung 29 ist eine radial umlaufende Ringrippe 17 angeformt. Aus der Darstellung von Figur 3 ist ersichtlich, dass an der Außenseite 9 eine Mehrzahl von Vertiefungen 18 vorgesehen sind, welche segmentweise in radialer Richtung im Abstand zueinander angeordnet sind. Die Vertiefungen 18 erstrecken sich in axialer Richtung von der Oberkante 30 des Vorsprungs 10 bis etwa zur halben Höhe des Vorsprungs 10 (Figur 4). Statt der Vertiefungen 18 können auch Öffnungen vorgesehen sein.The flow cup is shown in a side view in FIG. 5, the container 1 being shown in section. The central region of the container bottom 23 is shown in the detailed view X of FIG. A hollow cylindrical projection 10 is formed on the container bottom 23, the wall 29 of which projects vertically outwards from the container bottom 23. The projection 10 is integrally connected to the container bottom 23. The central axis A of the hollow cylindrical projection 10 is arranged concentrically to the central axis of the container 1. Likewise concentric to this axis A, a ventilation opening 4 is made in the container bottom 23. The ventilation opening 4 is enclosed by an annular wall 8. A radially encircling annular rib 17 is formed on the outside 9 of the wall 29. It can be seen from the illustration in FIG. 3 that a plurality of depressions 18 are provided on the outer side 9 and are arranged in segments in the radial direction at a distance from one another. The depressions 18 extend in the axial direction from the upper edge 30 of the projection 10 to approximately half the height of the projection 10 (FIG. 4). Instead of the depressions 18, openings can also be provided.
An dem Deckel 2 sind, wie in Figur 5 dargestellt, jeweils über Abreißlaschen 25 zwei Verschlusselemente 5 angeformt. Die Abreißlaschen 25 sind als Sollbruchstellen ausgebildet, damit die Verschlusselemente 5 manuell ohne Zuhilfenahme von Werkzeug vom Deckel 2 abgerissen werden könne. Die Verschlusselemente 5 sind jeweils identisch zueinander und dienen einerseits zum Verschließen der Belüftungsöffnung 4 und andererseits zum Verschließen der Auslassöffnung 19.As shown in FIG. 5, two closure elements 5 are formed on the cover 2 via tear-off tabs 25. The tear-off tabs 25 are designed as predetermined breaking points so that the closure elements 5 can be torn off the lid 2 manually without the aid of tools. The closure elements 5 are identical to each other and serve on the one hand to close the ventilation opening 4 and on the other hand to close the outlet opening 19.
Wie aus der Detailansicht Y von Figur 5 ersichtlich, weist das Verschlusselement 5 einen hohlzylindrischen Grundkörper 11 und einen mit diesem einstückig ausgebildeten Deckel 26 auf. In einem zentralen Bereich ist der Deckel 26 ins Innere des Grundkörpers 11, also in der Detailansicht Y von Figur 1 nach unten, zur Bildung eines Zapfens 12 eingebuchtet. An der Unterseite dieses Zapfens 12 ist ein nach unten sich konisch verjüngender Stopfen 13 angeformt. Die Unterseite 27 des Stopfens 3 ragt über die Unterkante 28 des Grundkörpers 11 hinaus. An der Außenseite des hohlzylindrischen Grundkörpers 11 sind zwei parallel und im Abstand zueinander verlaufende Ringnute 15 und 16 angeformt. Zum Verschließen der Belüftungsöffnung 4 wirkt eines der beiden Verschlusselemente 5 mit dem Vorsprung 10 am Behälterboden 23 zur Bildung eines Ventils zusammen, wobei der Vorsprung 10 das Ventilgehäuse und das Verschlusselement 5 den Ventildeckel bildet. Das Ventil ist hierbei als Doppelventil mit zwei in Strömungsrichtung hintereinander angeordneten und voneinander getrennten Ventilsitzen ausgebildet ist. Jeder Ventilsitz weist eine eigene Dichtfläche 6 bzw. 7 auf. Das Zusammenwirken von Verschlusselement 5 und Vorsprung 10 zur Bildung des Ventils, mit dem die Belüftungsöffnung 4 verschließbar ist, ist in Figur 4 näher dargestellt. Das Verschlusselement 5 wird hierzu über den Vorsprung 10 geschoben, so dass der hohlzylindrische Grundkörper 11 die zylindrische Wandung des Vorsprungs 10 umgreift. Um ein dichtes Anliegen des Verschlusselements 5 am Vorsprung 10 zu gewährleisten, ist der Innendurchmesser des hohlzylindrischen Grundkörpers 11 und der Außendurchmesser des hohlzylindrischen Vorsprungs 10 etwa gleich groß.As can be seen from the detailed view Y of FIG. 5, the closure element 5 has a hollow cylindrical base body 11 and a cover 26 formed integrally therewith. In a central area, the cover 26 is indented into the interior of the base body 11, that is to say in the detailed view Y of FIG. 1, to form a pin 12. A downwardly conically tapering plug 13 is formed on the underside of this pin 12. The underside 27 of the stopper 3 protrudes beyond the lower edge 28 of the base body 11. On the outside of the hollow cylindrical base body 11, two parallel and spaced-apart annular grooves 15 and 16 are formed. To close the ventilation opening 4, one of the two closure elements 5 cooperates with the projection 10 on the container bottom 23 to form a valve, the projection 10 forming the valve housing and the closure element 5 forming the valve cover. The valve is designed as a double valve with two valve seats arranged one behind the other in the flow direction and separated from one another. Each valve seat has its own sealing surface 6 or 7. The interaction of the closure element 5 and the projection 10 to form the valve with which the ventilation opening 4 can be closed is shown in more detail in FIG. For this purpose, the closure element 5 is pushed over the projection 10, so that the hollow cylindrical base body 11 engages around the cylindrical wall of the projection 10. In order to ensure that the closure element 5 bears tightly against the projection 10, the inside diameter of the hollow cylindrical base body 11 and the outside diameter of the hollow cylindrical projection 10 are approximately the same size.
Durch Zusammenwirken der Nuten 15 und 16 an der Innenseite des Grundkörpers 11 und der Ringrippe 17 an der Außenseite des Vorsprungs 10 ist das durch das Verschlusselement 5 und den Vorsprung 10 gebildete Ventil in zwei Ventilstellungen fixierbar. In der in Figur 4 (a) gezeigten Ventilstellung greift die Ringrippe 17 in die obere Ringnut 15 ein und die Unterkante 28 des hohlzylindrischen Grundkörpers 11 sitzt auf dem Behälterboden 23 auf. Gleichzeitig greift der Stopfen 13 in die Belüftungsöffnung 4 ein. Die Außenfläche des Stopfens 13 liegt hierbei an der Wandung 8 der Blüftungsöffnung 4 dicht an. Auf diese Weise wird ein erster Ventilsitz mit einer ersten Dichtfläche 6 gebildet. Daneben ist gleichzeitig ein zweiter Ventilsitz mit einer von der ersten Dichtfläche 6 getrennten zweiten Dichtfläche 7 gebildet, indem die Innenseite des Grundkörpers 11 dicht an der Außenwand 9 des hohlzylindrischen Vorsprungs 10 anliegt. In dieser Ventilstellung ist die Belüftungsöffnung 4 einerseits durch den ersten Ventilsitz (der durch das Eingreifen des Stopfens 13 in die Belüftungsöffnung 4 gebildet ist) und andererseits über den zweiten Ventilsitz (der durch das Anliegen der Innenseite 14 des Grundkörpers 11 am unteren Rand der Außenwand 9 gebildet ist) dicht verschlossen. Sollte eine geringe Menge Farbe durch den ersten Ventilsitz mit der ersten Dichtfläche 6 aus der Belüftungsöffnung 4 herausfließen, wird der weitere Fluss dieser Farbe aus dem Behälter 1 durch den zweiten Ventilsitz verhindert.By interaction of the grooves 15 and 16 on the inside of the base body 11 and the annular rib 17 on the outside of the projection 10, the valve formed by the closure element 5 and the projection 10 can be fixed in two valve positions. In the valve position shown in FIG. 4 (a), the annular rib 17 engages in the upper annular groove 15 and the lower edge 28 of the hollow cylindrical base body 11 is seated on the container bottom 23. At the same time, the plug 13 engages in the ventilation opening 4. The outer surface of the plug 13 lies tight against the wall 8 of the ventilation opening 4. In this way, a first valve seat with a first sealing surface 6 is formed. In addition, a second valve seat is simultaneously formed with a second sealing surface 7 separate from the first sealing surface 6, in that the inside of the base body 11 lies tightly against the outer wall 9 of the hollow cylindrical projection 10. In this valve position, the ventilation opening 4 is on the one hand through the first valve seat (which is formed by the engagement of the plug 13 in the ventilation opening 4) and on the other hand via the second valve seat (which is due to the inner side 14 of the base body 11 resting on the lower edge of the outer wall 9 is tightly sealed. Should a small amount of paint flow out of the ventilation opening 4 through the first valve seat with the first sealing surface 6, the further flow of this paint out of the container 1 through the second valve seat is prevented.
Zum Öffnen der Belüftungsöffnung 4 kann das Verschlusselement 5 in eine zweite Ventilstellung gebracht werden, wie sie in Figur 4 (b) dargestellt ist. Hierzu wird das Verschlußelement nach oben, also vom Behälterboden 23, angehoben, bis die Ringrippe 17 in die untere Ringnut 16 eingreift (Figur 4 (b)). Um dieses Anhebendes Verschlußelements 5 von der ersten in die zweite Ventilstellung zu erleichtern und den anfänglichen Sitz der Ringrippe 19 in der oberen Ringnut 15 zu lösen, ist es vorteilhaft, wenn der Deckelteil 26 des Verschlusselements 5 seitlich über den Grundkörper 11 hervorsteht. Dadurch wird nämlich einerseits ein leichteres Ergreifen des Verschlusselements am Deckel 26 ermöglicht und andererseits kann durch Verbiegen des überstehenden Bereichs des Deckels 26 der Eingriff der Ringrippe 17 in die obere Ringnut 15 gelöst werden, weil durch Hochbiegen dieser überstehenden Bereiche des Deckelteils 26 der Innendurchmesser im Bereich des Grundkörpers 11 vergrößert wird.To open the ventilation opening 4, the closure element 5 can be brought into a second valve position, as shown in FIG. 4 (b). For this, the Closure element raised, that is from the container bottom 23, until the annular rib 17 engages in the lower annular groove 16 (FIG. 4 (b)). In order to facilitate this lifting of the closure element 5 from the first into the second valve position and to release the initial seating of the annular rib 19 in the upper annular groove 15, it is advantageous if the cover part 26 of the closure element 5 protrudes laterally beyond the base body 11. On the one hand, this makes it easier to grip the closure element on the cover 26, and on the other hand, by bending the protruding area of the cover 26, the engagement of the annular rib 17 in the upper annular groove 15 can be released, because by bending these protruding areas of the cover part 26, the inside diameter in the area of the base body 11 is enlarged.
In der in Figur 4 (b) gezeigten zweiten Ventilstellung ist der Stopfen 13 außer Eingriff mit der Belüftungsöffnung 4, so dass diese freigegeben ist. Gleichzeitig ist auch der zweite Ventilsitz gelöst, weil nämlich in dieser Ventilstellung die Unterkante 28 des Grundkörpers 11 im Bereich der Vertiefungen 18 an der Außenseite des Vorsprungs 10 liegt, wie aus Figur 4 (b), rechte Seite, ersichtlich. In dieser Stellung ist ein Luftdurchtritt vom Innern des Behälters 1 durch die Belüftungsöffnung 4 und durch den zwischen den Vertiefungen 18 und der Innenseite 14 des Grundkörpers 11 gebildeten Durchlass ermöglicht.In the second valve position shown in FIG. 4 (b), the plug 13 is out of engagement with the ventilation opening 4, so that the latter is released. At the same time, the second valve seat is also loosened, because in this valve position the lower edge 28 of the base body 11 lies in the region of the depressions 18 on the outside of the projection 10, as can be seen from the right-hand side in FIG. 4 (b). In this position, air can pass from inside the container 1 through the ventilation opening 4 and through the passage formed between the recesses 18 and the inside 14 of the base body 11.
Das zweite, am Deckel 2 angeformte Verschlusselement 5, welches identisch zum anderen Verschlusselement 5 ausgebildet ist, kann zum Verschließen der Auslassöffnung 19 am Anschlussteil des Deckels 2 verwendet werden, indem dieses Verschlusselement 5 zunächst vom Deckel 2 abgebrochen und dann auf den Auslassstutzen 20 aufgesetzt wird. Der Innendurchmesser des Grundkörpers 11 und der Außendurchmesser des Auslassstutzens 20 sind hierfür aufeinander abgestimmt, damit die Innenseite 14 des Grundkörpers 11 dicht an der Außenseite des Stutzens 20 anliegt, wie in Figur 6 gezeigt.The second closure element 5 formed on the cover 2, which is identical to the other closure element 5, can be used to close the outlet opening 19 on the connection part of the cover 2 by first breaking off this closure element 5 from the cover 2 and then placing it on the outlet connector 20 , For this purpose, the inner diameter of the base body 11 and the outer diameter of the outlet connector 20 are coordinated with one another so that the inside 14 of the base body 11 lies tightly against the outside of the connector 20, as shown in FIG.
In der Figur 7 ist ein weiteres Ausführungsbeispiel eines Ventils zum Verschließen der Belüftungsöffnung dargestellt. Figur 7a zeigt eine Draufsicht dieses Ventils, welches ebenso wie das oben beschriebene Ventil zwei in Strömungsrichtung hintereinander angeordnete Ventilsitze aufweist. Gleiche Bauteile dieses Ventils sind mit den gleichen Bezugszeichen versehen wie in den Figuren 3 - 5. Wie bei dem in diesen Zeichnungen dargestellten Ausführungsbeispiel bildet auch bei dem in Figur 7 gezeigten Ventil der Vorsprung 10 das Ventilgehäuse und ein Verschlusselement 5 bildet den Ventildeckel. Das Ventil ist ebenfalls als Doppelventil mit zwei voneinander getrennten Ventilsitzen ausgebildet, wobei jeder Ventilsitz eine eigene Dichtfläche 6 bzw. 7 aufweist. Das Verschlusselement 5 ist klemmend über den Vorsprung 10 geschoben, so dass der hohlzylindrische Grundkörper 11 die zylindrische Wandung des Vorsprungs 10 umgreift. Das Verschlusselement 5 weist im Zentrum einen zylindrischen Stopfen 13 auf, der bei geschlossener Ventilstellung in die Belüftungsöffnung 4 eingreift und dort die erste Dichtfläche 6 bildet. Die zweite Dichtfläche 7 ist wiederum an der Außenwand 9 des Vorsprungs 10 gebildet, wo die Innenfläche 14 des Verschlusselementgrundkörpers 11 anliegt.FIG. 7 shows a further exemplary embodiment of a valve for closing the ventilation opening. FIG. 7a shows a top view of this valve which, like the valve described above, has two valve seats arranged one behind the other in the flow direction. The same components of this valve are provided with the same reference numerals as in FIGS. 3-5. As in the exemplary embodiment shown in these drawings, the projection 10 also forms the valve housing in the valve shown in FIG. 7 and a closure element 5 forms the valve cover. The valve is also formed as a double valve with two separate valve seats, each valve seat having its own sealing surface 6 or 7. The closure element 5 is slid over the projection 10 so that the hollow cylindrical base body 11 engages around the cylindrical wall of the projection 10. The closure element 5 has a cylindrical plug 13 in the center, which engages in the ventilation opening 4 when the valve position is closed and forms the first sealing surface 6 there. The second sealing surface 7 is in turn formed on the outer wall 9 of the projection 10, where the inner surface 14 of the closure element base body 11 bears.
Anders als bei den Ausführungsbeispielen der Figuren 3 - 5 sitzt das Verschlusselement 5 bei dem Ausführungsbeispiel der Figur 7 nicht über einen Rastmechanismus sondern klemmend über dem Vorsprung 10 auf. Das Verschlusselement 5 ist zwischen einer ersten Grenzstellung und einer zweiten Grenzstellung verschieblich, wobei in der ersten Grenzstellung, wie sie in der Figur 7a und 7b gezeigt ist, das Ventil geöffnet ist und in der zweiten Grenzstellung, wie sie in der Figur 8a bzw. 8b gezeigt ist, ist das Ventil geschlossen. An der Außenseite des Vorsprungs 10 ist eine Ringrippe 17a angeformt. An der Innenfläche des hohlzylindrischen Grundkörpers 11 des Verschlusselements 5 ist eine Ringnut 15a vorgesehen, welche mit der Ringrippe 17a zur Bildung von zwei Anschlägen in der ersten bzw. in der zweiten Ventilstellung zusammenwirkt. In der in Figur 7 gezeigten Ventilstellung liegt die Unterkante der Ringnut 15a an der Ringrippe 17a an und in der in Figur 18 gezeigten geschlossenen Ventilstellung liegt die Oberkante der Ringnut 15a an der Ringrippe 17a an. Zwischen diesen beiden Ventilstellungen ist das Verschlusselement 5 gegenüber dem Vorsprung 10 verschieblich.In contrast to the exemplary embodiments in FIGS. 3-5, the closure element 5 in the exemplary embodiment in FIG. 7 does not sit on a locking mechanism, but rather clamps over the projection 10. The closure element 5 is displaceable between a first limit position and a second limit position, the valve being open in the first limit position, as shown in FIGS. 7a and 7b, and in the second limit position, as shown in FIGS. 8a and 8b is shown, the valve is closed. An annular rib 17a is formed on the outside of the projection 10. On the inner surface of the hollow cylindrical base body 11 of the closure element 5, an annular groove 15a is provided, which cooperates with the annular rib 17a to form two stops in the first and in the second valve position. In the valve position shown in FIG. 7, the lower edge of the annular groove 15a bears against the annular rib 17a and in the closed valve position shown in FIG. 18 the upper edge of the annular groove 15a bears against the annular rib 17a. The closure element 5 is displaceable relative to the projection 10 between these two valve positions.
In einem hier nicht zeichnerisch dargestellten Ausführungsbeispiel des Fließbechers ist vorgesehen, dass die Belüftungsöffnung 4 zunächst durch eine dünne Membran verschlossen ist und erst beim Einsetzen des Verschlusselements 5 in die erste Ventilstellung eingestochen wird, indem eine am Stopfen 13 des Verschlusselements 5 angeformte Spitze die dünne Membran durchstößt.In an embodiment of the flow cup, which is not shown here in the drawing, it is provided that the ventilation opening 4 is initially closed by a thin membrane and is only inserted into the first valve position when the closure element 5 is inserted by a tip formed on the plug 13 of the closure element 5 by the thin membrane pierces.
Aufgrund der Ausbildung von zwei separaten Ventilsitzen mit jeweils einer Dichtfläche 6 bzw. 7 wird ein dichter Verschluss der Belüftungsöffnung 4 bei dem erfindungsgemäßen Fließbecher ermöglicht. Gegenüber den aus dem Stand der Technik bekannten Maßnahmen zum Verschließen der Belüftungsöffnung im Behälterboden zeichnet sich dieser Verschluss durch eine wesentlich bessere Dichtigkeit aus. Dies erlaubt es schliesslich, den Behälter auf dem Boden abzustellen, ohne dass die in dem Behälter befindliche Farbe herausläuft. Dadurch wird insbesondere ermöglicht, die Farbe in dem Behälter anzumischen, bevor der Behälter dann in üblicher Weise auf die Farbspritzpistole aufgesetzt wird. Das Ventil zum Verschließen der Belüftungsöffnung zeichnet sich ferner dadurch aus, dass das Verschlußelement 5 leicht wieder vom Behälter weggenommen werden kann, indem das Verschlußelement vom Vorsprung manuell durch Lösen der Rastverbindung abgezogen wird. Auf diese Weise wird ermöglicht, dass überschüssige Farbe, welche beim Lackiervorgang nicht gebraucht wurde, durch die Belüftungsöffnung ausfliessen und einer Wiederverwertung zugeführt werden kann, wenn der Behälter mit dem Behälterboden nach unten gehalten wird.Due to the formation of two separate valve seats, each with a sealing surface 6 or 7, a tight closure of the ventilation opening 4 is made possible in the flow cup according to the invention. This closure is distinguished from the measures known from the prior art for closing the ventilation opening in the container bottom by a much better tightness. This finally allows the container to be placed on the floor without the paint in the container running out. This in particular enables the paint to be mixed in the container before the container is then placed onto the paint spray gun in the usual way. The valve for closing the ventilation opening is further characterized in that the closure element 5 can be easily removed from the container again by manually pulling the closure element off the projection by releasing the latching connection. This enables excess paint, which was not used during the painting process, to flow out through the ventilation opening and to be recycled if the container is held with the container bottom down.
In einem alternativen, hier nicht zeichnerisch dargestellten Ausführungsbeispiel liegt die Belüftungsöffnung 4 und der diese umgebende Vorsprung 10 azentrisch bezüglich der Längsmittelachse des Behälters 1, d.h. die Belüftungsöffnung 4 sowie die Mittelachse A des Vorsprungs 10 liegen außermittig bezüglich des Becherbodens 23.In an alternative embodiment, not shown here in the drawing, the ventilation opening 4 and the projection 10 surrounding it lie eccentrically with respect to the longitudinal central axis of the container 1, i.e. the ventilation opening 4 and the central axis A of the projection 10 are located eccentrically with respect to the cup base 23.
Weiterhin kann das Ventil zum Verschließen der Belüftungsöffnung 4 so ausgebildet sein, dass es in mehr als zwei Ventilstellungen einstellbar ist. Hierfür ist beispielsweise vorgesehen, dass mehr als zwei Ringnute 15, 16 an der Außenseite des hohlzylindrischen Grundkörpers 11 angeordnet sind. Alternativ zu einer Mehrzahl von Ringnuten zur Bildung eines in mehreren Stellungen verrastbaren Ventils können auch parallel und im Abstand zueinander verlaufende Doppelringnute ausgebildet sein. Furthermore, the valve for closing the ventilation opening 4 can be designed such that it can be adjusted in more than two valve positions. For this purpose, it is provided, for example, that more than two ring grooves 15, 16 are arranged on the outside of the hollow cylindrical base body 11. As an alternative to a plurality of ring grooves to form a valve which can be locked in several positions, double ring grooves running parallel and at a distance from one another can also be formed.
