Description

Kindersicherer SchraubverschlußChildproof screw cap

Die vorliegende Erfindung betrifft einen gegen Überdrehen festen kindersicheren Schraubverschluß (bekannt aus US-A 4 436 211). Derartige kindersichere Schraubverschlüsse werden für Vorratsbehältnisse mit Haushaltschemikalien oder dergleichen verwendet, insbesondere für Reinigungsflüssigkeiten enthaltende Flaschen. Der Verschluß ist gleichwohl auch für andere Behältnisse, wie z. B. Arzneien enthaltende geeignet.The present invention relates to a childproof screw closure which is resistant to overturning (known from US Pat. No. 4,436,211). Such childproof screw caps are used for storage containers with household chemicals or the like, in particular for bottles containing cleaning liquids. The closure is also for other containers, such as. B. suitable containing medicinal products.

Bekannt sind Verschlüsse für Reinigerflaschen, bei denen das Öffnen durch Zusammenpressen gegenüberliegender Schraubkappenpartien und gleichzeitiges Drehen im Gegenuhrzeigersinn vorgenommen wird.Closures for detergent bottles are known in which the opening is carried out by pressing opposing screw cap parts together and simultaneously rotating them counterclockwise.

Ein Überdrehen dieser Verschlüsse beim Verschließen ist durch entsprechend starke Dimensionierung des eingesetzten Gewindes erschwert, die Kindersicherung besteht in entsprechende Anschläge der Schraubkappe radial spreitenden auf der Flasche befindlichen Rasten, wobei die Anschläge in geschlossenem Zustand hinter diesen anliegen. Die Schraubkappe ist dabei zweiteilig ausgebildet, die Peripherie stellt die eigentliche (die Anschläge tragende) elastisch durch Handkraft verformbare Kappe dar, innen ist konzentrisch ein Gewindeteil angeordnet.Overtightening these closures when closing is made difficult by the correspondingly large dimensioning of the thread used, the childproof lock consists in corresponding stops of the screw cap which have radially spreading catches on the bottle, the stops being behind them in the closed state. The screw cap is formed in two parts, the periphery represents the actual (carrying the stops) elastically deformable by hand force, inside a threaded part is arranged concentrically.

Wegen der notwendigerweise stark auszulegenden Gewinde und der dadurch bedingten Hinterschneidungen werden derartige Flaschen und ihre Verschlüsse im Blasverfahren hergestellt.Because of the necessary strong thread design and the resulting undercuts, such bottles and their closures are manufactured using the blowing process.

Die vorliegende Erfindung hat sich daher die Aufgabe gestellt, einen Schraubverschluß der eingangs geschilderten Art zu schaffen, der unter gleichzeitiger Erhöhung der Funktionssicherheit im Spritzgußverfahren herstellbar ist.The present invention has therefore set itself the task of creating a screw closure of the type described above, which can be manufactured in an injection molding process while increasing the functional reliability.

Die Lösung dieser Aufgabe gelingt bei einem überdrehfesten kindersicheren Schraubverschluß für Reinigungsflüssigkeiten enthaltende Vorratsflaschen, bestehend aus auf dem Gefäß angeordnetem Ausgießer mit Außengewinde und angeformten radial spreitenden Rasten sowie einer von den Rasten aufweitbaren, Anschläge aufweisenden Schraubkappe mit separatem Innengewindestück, der erfindungsgemäß die folgenden Merkmale besitzt:

  • a) der Ausgießer 1 weist ein zweigängiges Außengewinde 2 auf,
  • b) jeder Gang des Gewindes 2 umgreift einen Winkel von ::ii 180°,
  • c) die Gänge überlappen nicht oder nur unwesentlich,
  • d) zwischen den radial-spreitenden Rasten 3 und dem Ausgießer 1 sind Schwellen 4 angeordnet.
  • e) die Schraubkappe 5 weist ein entsprechendes zweigängiges Gewinde 6 auf dem Innengewindestück 7 auf.
  • f) das Innengewindestück 7 besitzt als Überdrehsicherung gegenüberliegende keilförmige Einschnitte 8 mit in aufgeschraubtem Zustand an den Schwellen 4 anliegenden Stoßkanten 9.
This problem is solved with an overtight childproof screw cap for storage bottles containing cleaning liquids, consisting of a spout arranged on the vessel with an external thread and molded radially spreading catches as well as a screw cap which can be expanded from the catches and has a screw cap with a separate internal thread piece which according to the invention has the following features:
  • a) the spout 1 has a two-start external thread 2,
  • b) each thread of thread 2 encompasses an angle of :: ii 180 ° ,
  • c) the gears do not overlap or only overlap,
  • d) sleepers 4 are arranged between the radially spreading notches 3 and the spout 1.
  • e) the screw cap 5 has a corresponding two-start thread 6 on the internal threaded piece 7.
  • f) the internal threaded piece 7 has opposite wedge-shaped incisions 8 as an anti-overturning device with abutting edges 9 in the screwed-on state on the sleepers 4.

Unter dem separaten Innengewindestück wird dabei ein vorzugsweise zylindrisches Teil mit Innengewinde.verstanden. An dieses ist die äußere Kappenhülle kopfseitig derart angeformt, daß sie sich mit Handkraft zur Freigabe der hinter den Rasten befindlichen Anschläge federnd zusammendrücken läßt.The separate internal threaded part is understood to mean a preferably cylindrical part with an internal thread. On this the outer cap shell is formed on the head side in such a way that it can be pressed together by hand to release the stops located behind the catches.

Durch die Kombination der oben genannten Merkmale ist ein Körper herstellbar, der hinterschneidungsfrei und somit im Spritzgußverfahren herstellbar ist.The combination of the above-mentioned features makes it possible to produce a body which can be manufactured without undercuts and thus by injection molding.

Durch die Ausbildung als zweigängiges Gewinde mit je einem Umschlingungswinkel von s180° entstehen auf dem Ausgießer zwei Gewindehalbgänge, wobei die obere Unterkante des Halbganges über dem oberen Kantenanfang des jeweiligen unteren Gewindehalbganges ausläuft. Ein derartiges Gewinde ist ohne Hinterschneidung herstellbar, jedoch auf relativ niedrige Gangtiefe beschränkt und somit nicht überdrehsicher.The design as a two-start thread, each with a wrap angle of s180 °, creates two half-threads on the spout, the upper lower edge of the half-thread running out over the upper edge of the respective lower half-thread. Such a thread can be produced without an undercut, but is limited to a relatively shallow pitch and is therefore not secure against overturning.

Erfindungsgemäß ist daher die Überdrehsicherung von der Schraubfunktion getrennt und als Stoßkanten-Schwellenpaar ausgelegt. Die Gewindeanfänge und ihre Steigungen sind dabei so ausgelegt, daß die Stoßkanten an die Schwellen bei vollkommen eingeschraubtem Verschluß anschlagen, wobei auch die Kappe normalerweise auf der Gefäßhülle aufliegt.According to the invention, the over-tightening device is therefore separated from the screwing function and is designed as a pair of abutting edges and thresholds. The thread starts and their pitches are designed so that the abutting edges hit the sleepers when the closure is fully screwed in, with the cap also normally resting on the vessel envelope.

Für das Gewinde hat sich eine Gangtiefe von ca. 0,5 mm bewährt, da hierdurch gleichzeitig ausreichende Stabilität und Funktion mit der geforderten Entformbarkeit kombiniert sind.A thread depth of approx. 0.5 mm has proven itself for the thread, as this simultaneously combines sufficient stability and function with the required demoldability.

Für die Herstellung im Spritzgußverfahren hat sich für den vorliegenden Zweck Polypropylen wegen seiner Materialeigenschaften gut bewährt. Die daraus hergestellten erfindungsgemäßen Verschlüsse greifen präzise, rasten auch nach häufigem Gebrauch kindersicher ein und die Federkonstante und damit die für das Öffnen benötigte Handkraft bleiben konstant. Ein die Funktionssicherheit beeinträchtigender Verschleiß, insbesondere Abrieb an den Materialkanten,konnte nicht beobachtet werden.For the present injection molding process, polypropylene has proven itself well because of its material properties. The closures according to the invention produced therefrom engage precisely, snap in childproof even after frequent use, and the spring constant and thus the manual force required for opening remain constant. A wear and tear, particularly abrasion on the material edges, which could impair the functional safety could not be observed.

Falls zur Materialersparnis die durch die keilförmigen Einschnitte entstehenden Stoßkanten zu schmal und damit scharfkantig ausfallen, wird vorgeschlagen, zur Schonung der Schwellen die Stoßkanten mit Plättchen zu versehen.If the abutting edges created by the wedge-shaped incisions are too narrow and therefore sharp-edged to save material, it is proposed to provide the abutting edges with plates to protect the sleepers.

Vorteilhafterweise befindet sich das Gewinde auf dem Ausgießer auf einem an diesem angeordneten Ring. Einmal kann damit die Gewindefläche vergrößert werden, zum anderen kann dieser Ring gleichzeitig als Anschlag für eine aufgeschobene und z. B. durch Prellverschuß gesicherte Spritzdüse oder dergleichen dienen.The thread on the spout is advantageously located on a ring arranged on the spout. On the one hand, the thread area can be enlarged, on the other hand, this ring can also serve as a stop for a deferred and z. B. secured by a bouncing spray nozzle or the like.

Als Formgeometrie hat sich für Schwellen und Rasten eine Stärke von ca.2 mm und für die Schwellen eine Breite von mindestens ca. 1 mm bewährt, wobei die Maße ohne weiteres an die jeweiligen Materialbedingungen angepaßt erhöht werden können.A thickness of approx. 2 mm has proven itself as the shape geometry for sleepers and notches and a width of at least approx. 1 mm for the sleepers, whereby the dimensions can be easily adapted to the respective material conditions.

Eine geringere Auslegung kann auch bei Verwendung des relativ harten und widerstandsfähigen Polypropylen zu Störungen der Funktionssicherheit führen.A smaller design can also lead to malfunctions in functional safety when using the relatively hard and resistant polypropylene.

Vorzugsweise ist der Verschluß mit dem Gefäßoberteil materialeinheitlich ausgeführt, wobei das im Spritzguß hergestellte Gefäßoberteil mit ihrem Unterteil z. B. durch Aufprellen und Verschweißen oder Verkleben verbunden wird.Preferably, the closure is made of the same material with the upper part of the vessel, the upper part of the vessel being produced by injection molding with its lower part, for. B. is connected by bouncing and welding or gluing.

Fig. 1 zeigt den auf einer Vorratsflasche 13 angeordneten zu verschließenden Ausgießer 1. Dieser Ausgießer trägt einen Ring 11, in den zwei halbe Gänge eines Außengewindes 2 eingeformt sind, die sich nicht bzw. nur unwesentlich überlappen, d. h., die obere Kante 14 des rechts dargestellten Gewindehalbganges beginnt unterhalb der Unterkante 15 des links dargestellten Gewindehalbganges. Auf der Platte 16 der Vorratsflasche 13, die den Ausgießer 1 trägt, sind weiterhin die Rasten 3 und die Schwellen 4 dargestellt, wobei die Rückseiten der Schwellen im vorliegenden Falle in die Rückseiten der Rasten 3 auslaufen.1 shows the pouring spout 1 to be closed, which is arranged on a storage bottle 13. This pouring spout carries a ring 11, in which two half gears of an external thread 2 are formed, which do not overlap or only overlap to an insignificant extent, ie. that is, the upper edge 14 of the thread half-way shown on the right begins below the lower edge 15 of the thread half-way shown on the left. The catches 3 and the sleepers 4 are also shown on the plate 16 of the storage bottle 13, which carries the spout 1, the rear sides of the sleepers in the present case running out into the rear sides of the catches 3.

Oberhalb des das zweigängige Gewinde 2 tragenden Ringes 11 ist ein Prellring 12 angeordnet. Uber diesen kann eine Spritzdüse geschoben und mit Hilfe des Prellringes 12 und eines entsprechenden Gegenstücks in der Düse gesichert werden, wobei sie am Durchrutschen nach unten hin durch den Ring 11 gehindert ist.A bouncing ring 12 is arranged above the ring 11 carrying the two-start thread 2. A spray nozzle can be pushed over this and secured in the nozzle by means of the bouncing ring 12 and a corresponding counterpart, whereby it is prevented from slipping downwards by the ring 11.

Fig. 2 zeigt das vorher beschriebene Oberteil einer Vorratsflasche in perspektivischer Draufsicht.Fig. 2 shows the previously described upper part of a storage bottle in a perspective top view.

Im Ausgießer 1 befinden sich die Öffnungen 17, durch die die Inhaltsflüssigkeit aus der Flasche ausgebracht wird. An den Ausgießer 1 sind gegenüberliegend die Schwellen 4 angeschlossen, die in die Rasten 3 auslaufen. Gegen die Vorderflächen 18 dieser Rasten, die bogen- oder keilförmig nach innen gezogen sind, drücken beim Aufschrauben der Kappe deren Aufweitkeile 19 (Fig. 3, 4) um diese über das Hindernis der Rasten 18 zu bewegen und an ihren Rückenflanken,in die die Aufweitkeile schließen, gegen ein Öffnen durch Kinder zu sichern.In the pourer 1 there are the openings 17 through which the liquid content is dispensed from the bottle. On the spout 1, the sleepers 4 are connected opposite, which run into the notches 3. Against the front surfaces 18 of these catches, which are drawn inward in an arc or wedge shape, when the cap is screwed on, the expansion wedges 19 (FIGS. 3, 4) are pressed to move them over the obstacle of the catches 18 and on their back flanks into which Close expanding wedges to prevent children from opening them.

Fig. 3 zeigt die Schraubkappe 5 für die Vorratsflasche. Diese besteht aus der äußeren Hülle 20, der eigentlichen Kappe und dem separaten, mit der Hülle 20 kopfseitig verbundenen Innengewindestück 7. Im Hintergrund der Hülle 20 ist ein Aufweitkeil 19 erkennbar.Fig. 3 shows the screw cap 5 for the storage bottle. This consists of the outer casing 20, the actual cap and the separate internal threaded piece 7 connected to the casing 20 on the head side. In the background of the casing 20 an expanding wedge 19 can be seen.

Hülle 20 und Innengewindestück sind derart miteinander verbunden, daß die Hülle 20 zum Schlie- βen und Öffnen ausreichend federt. Zur Stabilisierung weist die Schraubkappe Rippen 21 auf, um einen Winkel von 90° zu den Aufweitkeilen 19 versetzt befinden sich außen an der Hülle 20 Griffmulden 22, die ein Öffnen unter falschem Winkel verhindern.The sleeve 20 and the internal threaded piece are connected to one another in such a way that the sleeve 20 springs sufficiently for closing and opening. For stabilization, the screw cap has ribs 21, offset by an angle of 90 ° to the expansion wedges 19, recesses 22 on the outside of the casing 22, which prevent opening at the wrong angle.

Am unteren Teil des Innengewindestücks 7 ist das entsprechende 2-gängige Innengewinde 6 angeordnet. Das Innen gewindestück weist gegenüberliegende keilförmige Einschnitte 8 auf, die die Stoßkanten 9 bilden, die an die Schwellen 4 in aufgeschraubtem Zustand stoßen und ein Überdrehen verhindern. Der Winkel zwischen den sichernden Hinterkanten der Aufweitkeile 19 und den Stoßkanten 9 entspricht der projizierten Breite der Schwellen 4.The corresponding 2-thread internal thread 6 is arranged on the lower part of the internal thread piece 7. The internally threaded piece has opposite wedge-shaped incisions 8 which form the abutting edges 9 which abut the sleepers 4 in the screwed-on state and prevent over-tightening. The angle between the securing rear edges of the expanding wedges 19 and the abutting edges 9 corresponds to the projected width of the sleepers 4.
