Abstract

A closure for receptacles is provided which can be produced in one piece by injection molding or the like from plastic material and has a rigid pouring spout linked to the base of the cap-shaped, substantially rigid closure body which is disposed in swivelling fashion between a locked position folded down in the plane of the base and a position being approximately vertical thereto and is connected to the cap body via a membrane-like flexible wall portion. The pouring spout has at its circumference one or several bar projections, over which a bar projection engages which can be elastically bent outwards in the locked position to secure the pouring spout in this position.

Description

Die Erfindung betrifft einen Verschluß für Behälter zur Aufnahme von fließfähigem Füllgut mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a closure for containers for receiving flowable contents with the features of the preamble of claim 1.

Derartige kappenartige Verschlüsse mit schwenkbarer Ausgießtülle sind in verschiedenen Ausführungsformen bekannt. Es ist dabei zweckmäßig, den Verschluß mit allen seien Teilen einstückig, z.B. durch Spritzgießen herzustellen. Die Herstellung erfolgt dabei in derAusgießstellung der Tülle, wodurch in der demgegenüber verschwenkten Verschlußstellung der Tülle erhebliche Federungskräfte gespeichert sind, welche bestrebt sind, die Verschlußtülle wieder in die Offenstellung zu bewegen. Um jedoch zuverlässig als Verschluß zu wirken muß die Ausgießtülle in der Verschlußstellung ausreichend fest gegenüber diesen in Öffnungsrichtung wirkenden Kräften verriegelt werden.Such cap-like closures with a pivotable pouring spout are known in various embodiments. It is expedient for the closure to be in one piece with all its parts, e.g. manufactured by injection molding. The production takes place in the pouring position of the spout, as a result of which considerable spring forces are stored in the pivoted closure position of the spout, which endeavors to move the closure spout back into the open position. However, in order to act reliably as a closure, the pouring spout must be locked sufficiently firmly in the closed position against these forces acting in the opening direction.

Dies ist Aufgabe der vorliegenden Erfindung, die durch die Maßnahmen des Anspruchs 1 gelöst wird.This is the object of the present invention, which is achieved by the measures of claim 1.

Aufgrund dieser Ausbildung kann die Tülle über einen merklichen Teil ihrer Länge und auf ihren beiden Längsseiten gleichzeitig schnappartig und damit ausreichend fest an dem Verschlußkappenkörper verriegelt werden, wenn die Tülle in die Verschlußstellung verschwenkt wird. Außerdem ergibt sich der Vorteil, daß bei der Herstellung zwischen den miteinander schnappartig wir­kenden Teilen erhebliche Herstellungstoleranzen hingenommen werden können, ohne die sichere Verriegelung der Tülle in der Verschlußstellung zu gefährden.Due to this design, the spout can be locked over a noticeable part of its length and on its two longitudinal sides at the same time snap-fast and thus sufficiently firmly on the closure cap body when the spout is pivoted into the closed position. In addition, there is the advantage that considerable manufacturing tolerances can be tolerated in the manufacture between the parts acting in a snap-like manner without endangering the secure locking of the spout in the closed position.

Besonders vorteilhaft ist es, wenn die am Kappenkörper angeordneten Riegel­vorsprünge auf einer zum Kappenboden etwa parallelen, gegenüber diesem jedoch versenkt angeordneten starren Wandabschnitt des Kappenkörpers ange­ordnet sind, so daß sie eine stabile Ausbildung erfahren und über eine aus­reichende verriegelungswirksame Länge nach innen vorspringen können. Diese, die Riegelvorsprünge tragende Wand kann zugleich vorteilhafterweise als eine Verbindungswand zwischen der Umfangswand der Kapper einerseites und einer dazu konzentrischen Innenhülse ausgebildet sein, die sich vom Kappenboden nach innen erstreckt und an der der Rand des membranartig flexiblen Wandab­schnittes einstückig festgelegt sein kann. Dies erleichtert einerseits die Her­stellung und andererseits über die Länge der Hülse eine ausreichend große Ausdehnung des membranartig flexiblen Wandabschnittes, un ein leichtes Umschnappen dieses Wandabschnittes beim Verschwenken der Ausgießtülle zwischen ihren beiden Stellungen sicherzustellen und gleichzeitig übermäßigen Spannungen in diesem Wandabschnitt oder vorzeitige Materialermüdungen zu vermeiden.It is particularly advantageous if the locking projections arranged on the cap body are arranged on a rigid wall section of the cap body which is approximately parallel to the cap base, but is recessed relative to the latter, so that they have a stable design and can project inwards over a sufficient locking effective length. This wall carrying the locking projections can at the same time advantageously as one A connecting wall between the peripheral wall of the cap and a concentric inner sleeve can be formed, which extends inwards from the cap bottom and on which the edge of the membrane-like flexible wall section can be fixed in one piece. On the one hand, this facilitates the production and, on the other hand, a sufficiently large expansion of the membrane-like flexible wall section over the length of the sleeve, to ensure a slight snapping of this wall section when the pouring spout is pivoted between its two positions, and at the same time to avoid excessive tensions in this wall section or premature material fatigue.

Die Erfindung wird nachfolgend anhand schematischer Zeichnungen an einem Ausführungsbeispiel näher erläutert.The invention is explained in more detail below with the aid of schematic drawings using an exemplary embodiment.

Es zeigen:

  • Figur 1 einen Schnitt entlang der Schnittlinie I-I der Figur 2 und
  • Figur 2 einen Schnitt entlang der Schnittlinie II-II der Figur 1.
Show it:
  • 1 shows a section along the section line II of Figure 2 and
  • FIG. 2 shows a section along the section line II-II in FIG. 1.

Gemäß dem Ausführungsbeispiel weist der Verschluß 1 einen zylindrischen Verschlußkappenkörper 2 mit ebenem Kappenboden 3 auf. In Bezug auf das ver­wendete Kunststoffmaterial ist die Wanddicke des Kappenkörpers so gewählt, daß er relativ starr ist. Der Kappenkörper weist eine etwa rechteckförmige Vertiefung 22 auf, die nach unten durch eine zum Kappenboden 3 etwa parallele Wand 30 und zum Umfang hin durch eine entlang einer Sehne des Kappenumrisses verlaufende Wand 19 abgeschlossen ist. An der Stelle der Wand 19 ist der Kappenkörper zurückgenommen, um eine Griffmulde zum Öffnen des Verschlusses zu bilden. Im vorbestimmten Abstand von der entlang der Sehne angeordneten Wand 19 ragt eine dazu parallele gerade Wand 16 vom Kappenboden 3 nach unten. Im dargestellten Beispiel weisen die beiden Wände 16 und 19 einen gegenseitigen Abstand auf, der gleich oder etwas größer ist als der Radius des Kappenkörpers 2. Ferner ist zur Außenwand 2 des Kappen­körpers konzentrisch eine innere, vom Kappenboden 3 nach innen vorspringende Hülse 8 vorgesehen, die im Bereich der Ausnehmung 22 über die Wand 30 mit der Umfangswand 2 des Kappenkörpers verbunden ist.According to the exemplary embodiment, the closure 1 has a cylindrical closure cap body 2 with a flat cap base 3. With regard to the plastic material used, the wall thickness of the cap body is chosen so that it is relatively rigid. The cap body has an approximately rectangular recess 22 which is closed at the bottom by a wall 30 approximately parallel to the cap base 3 and to the circumference by a wall 19 running along a chord of the cap outline. At the location of the wall 19, the cap body is withdrawn to form a recessed grip for opening the closure. At a predetermined distance from the wall 19 arranged along the chord, a parallel straight wall 16 projects downward from the cap base 3. In the example shown, the two walls 16 and 19 are at a mutual distance which is equal to or slightly larger than the radius of the cap body 2. Furthermore, an inner sleeve 8, which projects inwards from the cap bottom 3, is provided concentrically with the outer wall 2 of the cap body is connected to the peripheral wall 2 of the cap body in the region of the recess 22 via the wall 30.

Im dem Bereich, entlang dem die Innenwand 16 mit dem Kappenkörper 3 ver­ bunden ist, ist über eine Gelenklinie 12, die durch eine Materialschwächung gebildet ist, ein Deckel 10 an dem Kappenboden 3 einstückig angelenkt, der in der Offenstellung in Fig. 1 gezeigt ist und der in der Verschlußstellung nach Fig. 2 die Vertiefung 22 der Kappe nach oben abdeckt. Der Deckel 10 weist ein freies Ende 11 auf, das in der Schließstellung nach Fig. 2 die Griffmulde am äußeren Umfang der Kappe überragt und so leicht mit den Fingern erfaßt werden kann.In the area along which the inner wall 16 ver with the cap body 3 is bound, via a hinge line 12, which is formed by a material weakening, a lid 10 is hinged to the cap base 3 in one piece, which is shown in the open position in FIG. 1 and which in the closed position according to FIG. 2, the recess 22 of the cap covering upwards. The lid 10 has a free end 11 which, in the closed position according to FIG. 2, projects beyond the recessed grip on the outer circumference of the cap and can thus be gripped easily with the fingers.

An der Umfangsseite des Deckels 10 ist einstückig eine langgestreckte Ausgießtülle 14 angeformt, deren Ausgießende 18 nach Verschwenken ent­sprechend dem Pfeil 17 in die Schließstellung mit der Wand 19 zusammenwirkt, während ihr inneres Ende eine angeformte Dichtungsmanschette 15 aufweist, die sich in der Schließstellung unter Vorspannung gegen die Wand 16 legt, so daß in der Verschlußstellung beide Enden der Ausgießtülle 14 zumindestens abgedeckt und das innere Ende zugleich abdichtend verschlossen ist.An elongated pouring spout 14 is integrally formed on the circumferential side of the cover 10, the pouring end 18 of which, after pivoting in accordance with the arrow 17, cooperates with the wall 19 in the closed position, while its inner end has an integrally formed sealing sleeve 15 which, in the closed position, is biased against the wall 16 lays so that in the closed position both ends of the pouring spout 14 are at least covered and the inner end is sealed at the same time.

Die Ausgießtülle 14 ist über den Deckelteil 10 mit dem Kappenboden 3 abdichtend und gelenkig verbunden. Im übrigen steht das innere Ende der Aus­gießtülle 14 mit dem Kappenkörper abdichtend aber beweglich über eine flexibel ausbiegbare Membran 4 in Verbindung. Diese ist mit den Kappenteilen einstückig ausgebildet und von gegenüber den anderen Teilen vergleichsweise geringer Dicke. In der Ebene des Kappenbodens 3 ist die Membran fest mit dem unteren Ende der Ausgießtülle 14 verbunden, wie dies bei 13 angedeutet ist. Außerdem ist der flexible Wandabschnitt 4 mit der Innenfläche der Hülse 8 entlang einer Ebene fest verbunden, die bei 5 angedeutet ist. Der mittlere Bereich des flexiblen Wandabschnittes 4 ist in der in Figur 1 dargestellten Offenstellung konvex nach außen ausgewölbt, wie durch die dick ausgezeichnete Linie 6 angedeutet ist. Wird die Ausgießtülle in der Verschlußstellung bewegt springt dagegen der Wandabschnitt 4 um und gelangt in die gestrichelt dargestellte konkav nach innen gewölbte Stellung 6a, wie sie in Fig. 1 gestrichelt dargestellt ist. Überbeanspruchungen des flexiblen Wandabschnittes werden durch seine relativ große Flächenausdehnung vermieden, die dadurch erreicht wird, daß die Hülse 8 weit in das Innere der Kappe hineinspringt und der flexible Wandab­schnitt 4 bis an das untere ende der Hülse 8 reicht.The pouring spout 14 is connected to the cap base 3 in a sealing and articulated manner via the cover part 10. Otherwise, the inner end of the pouring spout 14 is sealingly but movably connected to the cap body by means of a flexibly bendable membrane 4. This is formed in one piece with the cap parts and of comparatively small thickness compared to the other parts. In the plane of the cap base 3, the membrane is firmly connected to the lower end of the pouring spout 14, as indicated at 13. In addition, the flexible wall section 4 is fixedly connected to the inner surface of the sleeve 8 along a plane which is indicated at 5. The central region of the flexible wall section 4 is convexly curved outwards in the open position shown in FIG. 1, as indicated by the thick line 6. If the pouring spout is moved in the closed position, on the other hand, the wall section 4 jumps over and reaches the concave, inwardly curved position 6a, as shown in dashed lines in FIG. 1, in dashed lines. Overstressing of the flexible wall section is avoided by its relatively large surface area, which is achieved in that the sleeve 8 jumps far into the interior of the cap and the flexible wall section 4 extends to the lower end of the sleeve 8.

Zur Verriegelung der Ausgießtülle 14, die von beliebigem Querschnitt ausgebildet sein kann, weist diese an ihren Seiten langgestreckte Riegelabschnitte auf. Diese sind in dem bevorzugten dargestellten Ausführungsbeispiel als langgestreckte Leisten 20, 27 vorgesehen die sich entlang von diametral gegenüberliegenden Mantellinien der Ausgießtülle 14 erstrecken. Jeder Steg weist eine in der diametralen Ebene liegende in der Verschlußstellung nach oben weisende Ver­riegelungsfläche 20 und eine nach unten weisende abgeschrägte Auflauffläche 27 auf.To lock the pouring spout 14, which can be of any cross-section, it has elongated locking sections on its sides. In the preferred exemplary embodiment shown, these are elongated Strips 20, 27 are provided which extend along diametrically opposed surface lines of the pouring spout 14. Each web has a locking surface 20 lying in the diametrical plane in the closed position and an inclined ramp surface 27 pointing downward.

Ferner sind aus der zwischenwand 30 nach oben ragende Stege 21 bis 24 in einem gegenseitigen Abstand der Flächen 20 entsprechenden Abstand vorgesehen. Diese ragen von der Wand 30 nach oben in richtung auf den Kappenboden 3. An ihren oberen freien Kanten weisen sie in Richtung auf die Ausgießtülle 14 nach innen vorspringende Abbiegungen oder Wülste 23, 25 auf die so angeordnet sind, daß sie in der Verschlußstellung die Flächen 20 hintergreifen. Dadurch wird eine Verriegelung der Ausgießtülle in der Verschlußstellung erreicht, die eine Beibe­haltung dieser Verschlußstellung auch gegenüer erheblichen elastischen Rück­stellkräften oder gegen mechanische Einwirkungen auf den Griffabschnitt 11 des Deckels gewährleisten. Der Verriegelungseingriff erstreckt sich über einemerkliche Länge der Verschlußhülse 14, was den sicheren Halt begünstigt.Furthermore, webs 21 to 24 projecting upward from the intermediate wall 30 are provided at a corresponding distance at a mutual spacing of the surfaces 20. These protrude from the wall 30 upwards towards the cap base 3. At their upper free edges they point towards the pouring spout 14 inwardly projecting bends or ridges 23, 25 which are arranged so that they are in the closed position the surfaces 20 reach behind. As a result, the pouring spout is locked in the closed position, which ensures that this closed position is maintained even against considerable elastic restoring forces or against mechanical effects on the handle portion 11 of the lid. The locking engagement extends over a considerable length of the closure sleeve 14, which promotes a secure hold.
