Definitions
- the invention relates to a device for dispensing drops with a cap forming a spout, wherein the spout has a wall adjoining a large diameter end portion, which is partially formed as a ring throat, and having a diameter-reduced end portion adjoining the annular groove with an opening, wherein an extension axis of the spout extends through the opening and the large-diameter end portion.
- Drop dispensers are for example from the US 2,684,789 known.
- a cap closing a storage container has a spout which has a closure collar associated with a large diameter portion of the spout.
- the diameter of the spout decreases in the direction of an extension axis of the spout to form a ring throat, so that forms a concave outer wall.
- the outer wall merges into a small diameter end portion, in which there is an outlet opening for a stored in the container liquid or pasty mass.
- a similarly designed and functioning drop dispenser describes the DE 30 28 079 A1 , From the US 3,552,605 A a dropper is known in which on a bottleneck a grommet is clipped, which has a conical wall portion having at two opposite points indentations on which the summits of two opposing fingers can attack to compress the spout for the purpose of volume reduction.
- the US 2011/0163114 A1 and EP 0 254 810 A2 each describe dropper with spouts, which are curved radially outward.
- the invention has for its object to further develop a generic device nutzsvorteilhaft.
- the object is achieved by the invention specified in the claims.
- the wall of the annular throat is flexible.
- a force applied transversely to the extension direction of the extension axis on the spout leads to a tendency of the spout or by the Opening of the spout extending extension axis.
- a concavity forms in the area of the annular throat.
- the wall of the annular throat bulges in the inner volume of the cap. This leads to a reduction of the surrounding of the wall of the spout inner volume of the cap.
- the cap is preferably located on an opening of a cup part, which forms a storage container for a liquid or pasty mass. The container is thus enclosed around.
- the liquid or pasty mass in the container can only escape through the opening of the spout. If the drop dispenser is turned upside down before tilting of the small-diameter end portion so that the inner volume of the cap fills with the liquid or the pasty mass, part of the pasty mass or liquid escapes from the volume reduction caused by tilting and arching Outlet opening out.
- the flexible wall of the annular groove has sufficient restoring force to move the spout back to its original position after the transverse force has been removed. This leads to a slight suction effect, so that the part of the liquid or pasty mass, which is located in the small diameter end portion, is sucked back into the container.
- the spout is preferably made of a soft plastic, in particular polypropylene.
- the two end portions have a greater wall thickness, as the portion of the spout, which forms the annular groove.
- the annular groove may have a plurality of sections which follow one another in the axial direction. It is thus provided in particular that directly adjoining a diameter-largest edge of the spout, a strongly curved annular groove section follows. At this highly curved annular groove portion, a weakly curved annular groove section connects, which merges into the substantially cylindrical end portion.
- the end section is preferably associated with an actuation zone or an actuation section. This operating zone is haptically different from the adjacent zones. It can be a cylindrical zone. In the zone, the surface of the spout may be roughened.
- the end section is preferably a transversely to the direction of extension in the radial outward direction - with respect to the extension axis - projecting abragender actuating projection.
- This actuating projection forms a haptic resistance against which a user's finger can exert a force.
- This force may include an axial component and a radial component directed toward the axis to tilt the small diameter end portion of the spout relative to the large diameter end portion of the spout to form the above-mentioned indentation.
- the actuating projection may extend around the entire circumference of the rotationally symmetrical end portion.
- the projection may be formed by a collar protruding radially from the outer wall of the end section.
- protrude several individual projections in different directions of the spout It is, for example, provided that four identically shaped projections project in a uniform circumferential distribution about the extension axis in the radial direction outward from the spout.
- Each projection may have a fingertip attack surface.
- the fingertip attack surface may originate from the slightly grooved area of the spout to form a curve.
- One of the fingertip attack surface opposite flank portion of the actuating projection may lie in a plane. It may be a transverse plane to the extension axis.
- the actuating projection or the plurality of actuating projections may also have a floor plan which, like the outline of the collar, extends on a circular arc line.
- the spout is preferably formed as a rotational body.
- the wall of the curvature preferably extends continuously between a diameter-sized end section and a diameter-reduced end section on a convex curvature line, so that the inner wall of the spout has a funnel shape.
- the spout is made of a soft plastic, especially made of polypropylene and has the lowest wall thickness in the area of the annular throat.
- a smaller diameter outlet opening In the area of the opening of the small diameter end portion may be provided with a smaller diameter outlet opening.
- the outlet opening is preferably surrounded by an edge and lies in the axial direction away from the opening of the small-diameter end portion.
- the diameter of the outlet opening can thus be adapted to the viscosity of the material stored in the container. For dosing a liquid with a low viscosity, the outlet opening has a small diameter. For dosing a pasty mass with a high viscosity, the outlet opening has a large diameter.
- the diameter of the outlet opening can be widened to the diameter of the tubular diameter-small end portion, without having to change the design of the spout otherwise.
- the large diameter end portion of the spout is preferably connected to a mounting collar.
- the mounting collar is preferably made of a hard plastic, such as polypropylene.
- the cap is preferably made by 2K injection molding, for which purpose first the mounting collar is made and in the opening of the mounting collar, the spout is injected. The mounting collar is then in a radially outwardly projecting annular groove of the spout, so that the spout protrudes beyond the mounting collar in the axial direction of the extension axis of the spout in both directions.
- the mounting collar With the mounting collar, the attachment of the cap takes place on a preferably cup-shaped container, wherein the cap, an edge of the container is closed. A portion of the spout forms a sealing function by sealing against the inner wall of the edge of the container.
- the mounting collar preferably has latching means, for example an annular latching projection which engages over a Gegenrastwulst of the edge of the container when attaching the cap to the container. Means can be provided with which a rotationally fixed connection of the cap to the container is achieved.
- the anti-rotation preferably has interlocking positive locking means.
- the edge of the container may have a plurality of tooth-like projections extending around the entire circumference of the edge, leaving between them inlet openings for a securing projection of the fastening collar.
- the cap with a lid is closed.
- the lid preferably has a peripheral wall with an opening edge which can be placed on the large diameter end portion of the spout.
- the cap protrudes into the cavity of the lid, the bottom of which preferably has closure means which, when the lid is placed on the cap, close the opening of the small-diameter end section.
- the closure means may have a central sealing projection, which protrudes in the closed state into the opening of the small-diameter end portion.
- the tubular diameter-low end portion protrudes into an annular groove of the lid and is surrounded by an annular projection.
- the diameter-reduced end portion may have a sealing bead. This can be arranged within the opening, so be directed radially inwardly. He then lies on the central sealing projection.
- the sealing bead is in cross section in a point system on the sealing projection. It then forms a line-shaped seal around the sealing projection.
- the lid is preferably formed so that it can be plugged only in a straight direction, so that the spout does not kink when plugging the lid.
- the sealing bead can also point in the radial outward direction to abut against the inner wall of the annular projection.
- the latter can have a funnel-shaped opening, which simplifies the sliding in of the end section.
- the annular groove has sections with a different curvature.
- a highly curved groove portion whose contour line extends, for example, on a circular arc with a small radius, immediately adjoins the edge of the large diameter portion.
- a weakly curved annular groove section connects, which adjoins the actuating projection.
- This ring groove section also has a contour line which runs on a circular arc line. However, the arc has a larger radius.
- the filling of the device according to the invention is carried out in an assembled state in which the cap is inserted in the lid and the mounting collar of the spout is not yet connected to the container.
- the filling of the container can take place through the large diameter opening of the container. Only after filling the container, the spout inserted in the lid is placed on the edge of the container.
- the anti-rotation projections engage in the anti-rotation recesses and the locking projection engages behind the counter-locking projection, so that the cap is rotatably and tensile strength connected to the container.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung gebrauchsvorteilhaft weiterzubilden. Gelöst wird die Aufgabe durch die in den Ansprüchen angegebene Erfindung.The invention has for its object to further develop a generic device nutzsvorteilhaft. The object is achieved by the invention specified in the claims.
Zunächst und im Wesentlichen wird vorgeschlagen, dass die Wand der Ringkehle flexibel ist. Eine quer zur Erstreckungsrichtung der Erstreckungsachse auf die Tülle aufgebrachte Kraft führt zu einer Neigung der Tülle beziehungsweise der durch die Öffnung der Tülle hindurchgehenden Erstreckungsachse. Auf der Seite, gegen die die Tülle geneigt wird, bildet sich im Bereich der Ringkehle eine Einwölbung. Die Wand der Ringkehle wölbt sich in das Innenvolumen der Kappe. Dies führt zu einer Verminderung des von der Wandung der Tülle umgebenden Innenvolumens der Kappe. Die Kappe sitzt bevorzugt auf einer Öffnung eines Becherteiles, welches einen Bevorratungsbehälter für eine flüssige oder pastöse Masse ausbildet. Der Behälter ist somit ringsumschlossen. Die im Behälter befindliche Flüssigkeit oder pastöse Masse kann ausschließlich durch die Öffnung der Tülle entweichen. Wird der Tropfenspender vor dem Verkippen des durchmessergeringen Endabschnitts auf den Kopf gestellt, so dass sich das Innenvolumen der Kappe mit der Flüssigkeit oder der pastösen Masse füllt, so tritt ein Teil der pastösen Masse oder der Flüssigkeit zufolge der beim Verkippen und Einwölben verursachten Volumensverminderung aus der Austrittsöffnung heraus. Die flexible Wand der Ringkehle besitzt eine ausreichende Rückstellkraft, um die Tülle nach Aufheben der Querkraft wieder in die Ursprungsstellung zurück zu verlagern. Dies führt zu einer geringfügigen Sogwirkung, so dass sich der Teil der Flüssigkeit oder pastösen Masse, der sich im durchmessergeringen Endabschnitt befindet, wieder in das Behältnis hineingesogen wird. Die Tülle ist bevorzugt aus einem weichen Kunststoff, insbesondere Polypropylen, gefertigt. Sie besitzt Abschnitte mit verschiedenen Wandstärken. Bevorzugt besitzen die beiden Endabschnitte eine größere Wandstärke, als der Abschnitt der Tülle, der die Ringkehle ausbildet. Die Ringkehle kann mehrere, in Achsrichtung sich hintereinander anschließende Abschnitte aufweisen. So ist insbesondere vorgesehen, dass sich unmittelbar an einen durchmessergrößten Rand der Tülle ein stark gekrümmter Ringkehlenabschnitt anschließt. An diesen stark gekrümmten Ringkehlenabschnitt schließt sich ein schwach gekrümmter Ringkehlenabschnitt an, welcher in den im Wesentlichen zylinderförmigen Endabschnitt übergeht. Dem Endabschnitt ist bevorzugt eine Betätigungszone oder ein Betätigungsabschnitt zugeordnet. Diese Betätigungszone unterscheidet sich haptisch von den daran angrenzenden Zonen. Es kann sich um eine zylindrische Zone handeln. In der Zone kann die Oberfläche der Tülle aufgeraut sein. Sie kann radial nach außen abragende Noppen aufweisen. Dem Endabschnitt ist bevorzugt ein quer zur Erstreckungsrichtung in Radialauswärtsrichtung - bezogen auf die Erstreckungsachse - abragender Betätigungsvorsprung zugeordnet. Dieser Betätigungsvorsprung bildet einen haptischen Widerstand, gegen den der Finger eines Benutzers eine Kraft ausüben kann. Diese Kraft kann eine Axialkomponente und eine zur Achse hin gerichtete Radialkomponente aufweisen, um den durchmessergeringen Endabschnitt der Tülle gegenüber dem durchmessergroßen Endabschnitt der Tülle zu neigen, so dass sich die oben genannte Einwölbung ausbildet. Es reicht aber grundsätzlich aus, wenn gegen den Betätigungsvorsprung eine axiale Kraft ausgeübt wird. Da der Betätigungsvorsprung von der Achse beabstandet ist, bildet sich ein Drehmoment aus, welches die Verkippung des öffnungsseitigen Tüllenabschnitts zur Folge hat. Der Betätigungsvorsprung kann sich um den gesamten Umfang des rotationssymmetrisch gestalteten Endabschnitts erstrecken. Hierzu kann der Vorsprung von einem radial von der Außenwandung des Endabschnitts abragenden Kragen ausgebildet sein. Es ist aber auch vorgesehen, dass mehrere einzelne Vorsprünge in unterschiedliche Richtungen von der Tülle abragen. Es ist bspw. vorgesehen, dass vier gleich gestaltete Vorsprünge in gleichmäßiger Umfangsverteilung um die Erstreckungsachse in Radialrichtung nach außen von der Tülle abragen. Jeder Vorsprung kann eine Fingerkuppen-Angriffsfläche aufweisen. Die Fingerkuppen-Angriffsfläche kann unter Ausbildung einer Rundung aus dem schwach gekehlten Bereich der Tülle entspringen. Ein der Fingerkuppen-Angriffsfläche gegenüberliegender Flankenabschnitt des Betätigungsvorsprungs kann in einer Ebene liegen. Es kann sich dabei um eine Querebene zur Erstreckungsachse handeln. Der Betätigungsvorsprung oder die mehreren Betätigungsvorsprünge können aber auch einen Grundriss aufweisen, der wie der Grundriss des Kragens, auf einer Kreisbogenlinie verläuft. Die Tülle ist bevorzugt als Rotationskörper ausgebildet. Die Wandung der Krümmung verläuft zwischen durchmessergroßem Endabschnitt und durchmessergeringem Endabschnitt bevorzugt durchgängig auf einer konvexen Krümmungslinie, so dass die Innenwandung der Tülle eine Trichterform besitzt. Die Tülle ist aus einem weichen Kunststoff, insbesondere aus Polypropylen gefertigt und besitzt im Bereich der Ringkehle die geringste Wandstärke. Im Bereich der Öffnung des durchmessergeringen Endabschnitts kann eine Austrittsöffnung mit einem geringeren Durchmesser vorgesehen sein. Die Austrittsöffnung ist bevorzugt von einem Rand umgeben und liegt in Achsrichtung entfernt von der Öffnung des durchmessergeringen Endabschnitts. Der Durchmesser der Austrittsöffnung kann somit der Viskosität der in dem Behälter bevorrateten Masse angepasst werden. Zum Dosieren einer Flüssigkeit mit einer geringen Viskosität besitzt die Austrittsöffnung einen geringen Durchmesser. Zum Dosieren einer pastösen Masse mit einer großen Viskosität besitzt die Austrittsöffnung einen großen Durchmesser. Der Durchmesser der Austrittsöffnung kann bis auf den Durchmesser des rohrförmigen durchmessergeringen Endabschnitts aufgeweitet werden, ohne dass die Bauform der Tülle ansonsten geändert werden muss. Der durchmessergroße Endabschnitt der Tülle ist bevorzugt mit einem Befestigungskragen verbunden. Der Befestigungskragen ist vorzugsweise aus einem harten Kunststoff, beispielsweise Polypropylen, gefertigt. Die Kappe wird bevorzugt im 2K-Spritzgussverfahren gefertigt, wozu zunächst der Befestigungskragen gefertigt wird und in die Öffnung des Befestigungskragens die Tülle eingespritzt wird. Der Befestigungskragen liegt dann in einer radial auswärts ragenden Ringnut der Tülle, so dass die Tülle den Befestigungskragen in Achsrichtung der Erstreckungsachse der Tülle in beiden Richtungen überragt. Mit dem Befestigungskragen erfolgt die Befestigung der Kappe an einem bevorzugt becherförmigen Behälter, wobei mit der Kappe ein Rand des Behälters verschlossen wird. Ein Abschnitt der Tülle bildet hierbei eine Dichtfunktion aus, indem er dichtend an der Innenwand des Randes des Behälters anliegt. Der Befestigungskragen besitzt bevorzugt Rastmittel, beispielsweise einen ringförmigen Rastvorsprung, der beim Aufstecken der Kappe auf den Behälter einen Gegenrastwulst des Randes des Behälters übergreift. Es können Mittel vorgesehen sein, mit denen eine drehfeste Verbindung der Kappe zum Behälter erreicht wird. Die Verdrehsicherung besitzt bevorzugt ineinandergreifende Formschlussmittel. So kann der Rand des Behälters eine Vielzahl von zahnartig sich um den gesamten Umfang des Randes erstreckende Vorsprünge aufweisen, die zwischen sich Eintrittsöffnungen für einen Verdrehsicherungsvorsprung des Befestigungskragens belassen. Es ist ferner bevorzugt vorgesehen, dass die Kappe mit einem Deckel verschließbar ist. Der Deckel besitzt bevorzugt eine Umfangswandung mit einem Öffnungsrand, der auf den durchmessergroßen Endabschnitt der Tülle aufgesetzt werden kann. Es kann ein Gewinde vorgesehen sein, welches eine Gewinderippe aufweist, die mit einem Gewindeabschnitt des Befestigungskragens zusammenwirkt, so dass der Deckel auf den Befestigungskragen aufgeschraubt wird. Im verschlossenen Zustand ragt die Kappe in die Höhlung des Deckels, dessen Boden bevorzugt Verschlussmittel aufweist, die bei auf der Kappe aufgesetztem Deckel die Öffnung des durchmessergeringen Endabschnittes verschließen. Die Verschlussmittel können einen zentralen Dichtvorsprung aufweisen, der in verschlossenem Zustand in die Öffnung des durchmessergeringen Endabschnittes hineinragt. Der rohrförmige durchmessergeringe Endabschnitt ragt in eine Ringnut des Deckels und wird von einem ringförmigen Vorsprung umgeben. Der durchmessergeringe Endabschnitt kann einen Dichtwulst aufweisen. Dieser kann innerhalb der Öffnung angeordnet sein, also radial einwärts gerichtet sein. Er liegt dann am zentralen Dichtvorsprung an. Bevorzugt liegt der Dichtwulst im Querschnitt in einer Punktanlage am Dichtvorsprung an. Es bildet sich dann eine linienförmige Abdichtung um den Dichtvorsprung. Der Deckel ist vorzugsweise so ausgebildet, dass er nur in einer geraden Richtung aufgesteckt werden kann, so dass die Tülle beim Aufstecken des Deckels nicht abknickt. Der Dichtwulst kann aber auch in Radialauswärtsrichtung weisen, um an der Innenwandung des ringförmigen Vorsprungs anzuliegen. Letzterer kann eine trichterförmige Öffnung aufweisen, die das Hineingleiten des Endabschnitts vereinfacht. Die Ringkehle besitzt Abschnitte mit einer unterschiedlich starken Krümmung. Ein stark gekrümmter Ringkehlenabschnitt, dessen Konturlinie beispielsweise auf einer Kreisbogenlinie mit einem geringen Radius verläuft, schließt sich unmittelbar an den Rand des durchmessergroßen Abschnitts an. An diesen stark gekrümmten Ringkehlenabschnitt schließt sich ein schwach gekrümmter Ringkehlenabschnitt an, der bis an den Betätigungsvorsprung angrenzt. Auch dieser Ringkehlenabschnitt besitzt eine Konturlinie, die auf einer Kreisbogenlinie verläuft. Der Kreisbogen hat allerdings einen größeren Radius.First and foremost, it is proposed that the wall of the annular throat is flexible. A force applied transversely to the extension direction of the extension axis on the spout leads to a tendency of the spout or by the Opening of the spout extending extension axis. On the side against which the nozzle is tilted, a concavity forms in the area of the annular throat. The wall of the annular throat bulges in the inner volume of the cap. This leads to a reduction of the surrounding of the wall of the spout inner volume of the cap. The cap is preferably located on an opening of a cup part, which forms a storage container for a liquid or pasty mass. The container is thus enclosed around. The liquid or pasty mass in the container can only escape through the opening of the spout. If the drop dispenser is turned upside down before tilting of the small-diameter end portion so that the inner volume of the cap fills with the liquid or the pasty mass, part of the pasty mass or liquid escapes from the volume reduction caused by tilting and arching Outlet opening out. The flexible wall of the annular groove has sufficient restoring force to move the spout back to its original position after the transverse force has been removed. This leads to a slight suction effect, so that the part of the liquid or pasty mass, which is located in the small diameter end portion, is sucked back into the container. The spout is preferably made of a soft plastic, in particular polypropylene. It has sections with different wall thicknesses. Preferably, the two end portions have a greater wall thickness, as the portion of the spout, which forms the annular groove. The annular groove may have a plurality of sections which follow one another in the axial direction. It is thus provided in particular that directly adjoining a diameter-largest edge of the spout, a strongly curved annular groove section follows. At this highly curved annular groove portion, a weakly curved annular groove section connects, which merges into the substantially cylindrical end portion. The end section is preferably associated with an actuation zone or an actuation section. This operating zone is haptically different from the adjacent zones. It can be a cylindrical zone. In the zone, the surface of the spout may be roughened. It may have radially outwardly projecting nubs. The end section is preferably a transversely to the direction of extension in the radial outward direction - with respect to the extension axis - projecting abragender actuating projection. This actuating projection forms a haptic resistance against which a user's finger can exert a force. This force may include an axial component and a radial component directed toward the axis to tilt the small diameter end portion of the spout relative to the large diameter end portion of the spout to form the above-mentioned indentation. However, it is basically sufficient if an axial force is exerted against the actuating projection. Since the actuating projection is spaced from the axis, a torque is formed, which has the tilting of the opening-side Tüllenabschnitts result. The actuating projection may extend around the entire circumference of the rotationally symmetrical end portion. For this purpose, the projection may be formed by a collar protruding radially from the outer wall of the end section. But it is also envisaged that protrude several individual projections in different directions of the spout. It is, for example, provided that four identically shaped projections project in a uniform circumferential distribution about the extension axis in the radial direction outward from the spout. Each projection may have a fingertip attack surface. The fingertip attack surface may originate from the slightly grooved area of the spout to form a curve. One of the fingertip attack surface opposite flank portion of the actuating projection may lie in a plane. It may be a transverse plane to the extension axis. However, the actuating projection or the plurality of actuating projections may also have a floor plan which, like the outline of the collar, extends on a circular arc line. The spout is preferably formed as a rotational body. The wall of the curvature preferably extends continuously between a diameter-sized end section and a diameter-reduced end section on a convex curvature line, so that the inner wall of the spout has a funnel shape. The spout is made of a soft plastic, especially made of polypropylene and has the lowest wall thickness in the area of the annular throat. In the area of the opening of the small diameter end portion may be provided with a smaller diameter outlet opening. The outlet opening is preferably surrounded by an edge and lies in the axial direction away from the opening of the small-diameter end portion. The diameter of the outlet opening can thus be adapted to the viscosity of the material stored in the container. For dosing a liquid with a low viscosity, the outlet opening has a small diameter. For dosing a pasty mass with a high viscosity, the outlet opening has a large diameter. The diameter of the outlet opening can be widened to the diameter of the tubular diameter-small end portion, without having to change the design of the spout otherwise. The large diameter end portion of the spout is preferably connected to a mounting collar. The mounting collar is preferably made of a hard plastic, such as polypropylene. The cap is preferably made by 2K injection molding, for which purpose first the mounting collar is made and in the opening of the mounting collar, the spout is injected. The mounting collar is then in a radially outwardly projecting annular groove of the spout, so that the spout protrudes beyond the mounting collar in the axial direction of the extension axis of the spout in both directions. With the mounting collar, the attachment of the cap takes place on a preferably cup-shaped container, wherein the cap, an edge of the container is closed. A portion of the spout forms a sealing function by sealing against the inner wall of the edge of the container. The mounting collar preferably has latching means, for example an annular latching projection which engages over a Gegenrastwulst of the edge of the container when attaching the cap to the container. Means can be provided with which a rotationally fixed connection of the cap to the container is achieved. The anti-rotation preferably has interlocking positive locking means. Thus, the edge of the container may have a plurality of tooth-like projections extending around the entire circumference of the edge, leaving between them inlet openings for a securing projection of the fastening collar. It is further preferably provided that the cap with a lid is closed. The lid preferably has a peripheral wall with an opening edge which can be placed on the large diameter end portion of the spout. There may be provided a thread having a threaded rib which cooperates with a threaded portion of the mounting collar, so that the lid is screwed onto the mounting collar. In the closed state, the cap protrudes into the cavity of the lid, the bottom of which preferably has closure means which, when the lid is placed on the cap, close the opening of the small-diameter end section. The closure means may have a central sealing projection, which protrudes in the closed state into the opening of the small-diameter end portion. The tubular diameter-low end portion protrudes into an annular groove of the lid and is surrounded by an annular projection. The diameter-reduced end portion may have a sealing bead. This can be arranged within the opening, so be directed radially inwardly. He then lies on the central sealing projection. Preferably, the sealing bead is in cross section in a point system on the sealing projection. It then forms a line-shaped seal around the sealing projection. The lid is preferably formed so that it can be plugged only in a straight direction, so that the spout does not kink when plugging the lid. However, the sealing bead can also point in the radial outward direction to abut against the inner wall of the annular projection. The latter can have a funnel-shaped opening, which simplifies the sliding in of the end section. The annular groove has sections with a different curvature. A highly curved groove portion, whose contour line extends, for example, on a circular arc with a small radius, immediately adjoins the edge of the large diameter portion. At this highly curved annular groove portion, a weakly curved annular groove section connects, which adjoins the actuating projection. This ring groove section also has a contour line which runs on a circular arc line. However, the arc has a larger radius.
Die Befüllung der erfindungsgemäßen Vorrichtung erfolgt in einem Montagezustand, in dem die Kappe in dem Deckel steckt und der Befestigungskragen der Tülle noch nicht mit dem Behälter verbunden ist. Die Befüllung des Behälters kann durch die durchmessergroße Öffnung des Behälters hindurch erfolgen. Erst nach der Befüllung des Behälters wird die im Deckel steckende Tülle auf den Rand des Behälters aufgesetzt. Die Verdrehsicherungsvorsprünge greifen in die Drehsicherungsaussparungen und der Rastvorsprung hintergreift den Gegenrastvorsprung, so dass die Kappe drehfest und zugfest mit dem Behälter verbunden ist. Durch eine Viertelkreisdrehung kann der Deckel gegenüber der Kappe in eine Lösestellung gebracht werden und in Axialrichtung abgezogen werden.The filling of the device according to the invention is carried out in an assembled state in which the cap is inserted in the lid and the mounting collar of the spout is not yet connected to the container. The filling of the container can take place through the large diameter opening of the container. Only after filling the container, the spout inserted in the lid is placed on the edge of the container. The anti-rotation projections engage in the anti-rotation recesses and the locking projection engages behind the counter-locking projection, so that the cap is rotatably and tensile strength connected to the container. By a quarter-circle rotation of the lid relative to the cap can be brought into a release position and withdrawn in the axial direction.

Der durchmessergroße Endabschnitt 10 besitzt einen Außendurchmesser von 25 bis 35 mm und grenzt an einen ersten stark gekehlten Ringkehlenbereich 7 an. Der stark gekrümmte Ringkehlenbereich 7 bildet einen Wandabschnitt der Tülle 2 aus, der im Längsschnitt durch eine Erstreckungsachse A auf einer Kreisbogenlinie verläuft, die einen Radius von etwa 10 mm haben kann. An den stark gekehlten Bereich 7 schließt sich ein schwach gekehlter Bereich an, dessen Wandung entlang einer Kreisbogenlinie verläuft, deren Radius etwa 45 mm beträgt. Die beiden gekehlten Bereiche 6, 7 bilden einen Ringkehlenabschnitt aus, der rotationssymmetrisch zur Erstreckungsachse A verläuft, wobei die Erstreckungsachse A durch das Zentrum des durchmessergroßen Endabschnitts 10 und das Zentrum eines durchmesserkleinen Endabschnitts 4 der Tülle 2 verläuft, welcher sich an den schwach gekehlten Bereich 6 anschließt.
