Description
Die vorliegende Erfindung betrifft eine Sprühdose gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a spray can according to the preamble of Claim 1.
Derartige Sprühdosen finden in vielen Anwendungsgebieten Verwendung.
Dabei können sie mit an Luft aushärtendem PU-Schaum, Farben oder anderen
sprühfähigen Stoffen befüllt sein. Die Kappe bietet in jedem Fall einen Schutz des
Ventiles sowohl vor Verschmutzung sowie vor mechanischer Beschädigung.Such spray cans are used in many areas of application.
They can be filled with air-hardening PU foam, paints or other sprayable substances. In any case, the cap offers protection of the valve against contamination as well as against mechanical damage.
Es sind Sprühdosen bekannt (US 5 234 137), die durch Drehen eine Austrittsöffnung des Ventiles freigeben und nach Gebrauch durch Drehen dieser Austrittsöffnung wieder verschließen. In diesem Sinne werden vorzugsweise Sprühdosen verschlossen, die den genannten PU-Schaum beinhalten.Spray cans are known (US Pat. No. 5,234,137) that rotate an outlet opening release the valve and after use by turning this outlet opening close again. In this sense, spray cans are preferably closed, which contain the PU foam mentioned.
Nachteilig ist hierbei jedoch, daß die Kappen dieser Sprühdosen frei drehbar sind, so daß sie nicht mit Sicherheit in einer die Austrittsöffnung verdeckenden Stellung verharren. Vielmehr besteht die Gefahr, daß sie unbeabsichtigt verdreht werden und dabei die Austrittsöffnung freigelegt wird, wodurch der gewünschte Schutz nicht mehr gegeben ist.The disadvantage here, however, is that the caps of these spray cans are freely rotatable, so that they are not with certainty in a position covering the outlet opening remain. Rather, there is a risk that they will be accidentally twisted and the outlet opening is thereby exposed, whereby the desired protection is no longer given is.
Aber auch bei Sprühdosen mit anderem Inhalt besteht sehr häufig die Forderung, daß
die Kappe positioniert bleiben soll, was bislang nicht möglich ist.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Sprühdose der
gattungsgemäßen Art so auszubilden, daß ihre Funktionsfähigkeit insgesamt verbessert
wird.But even with spray cans with a different content, there is very often a requirement that the cap should remain positioned, which has not been possible until now.
The present invention is therefore based on the object of designing a spray can of the generic type in such a way that its overall functionality is improved.
Diese Aufgabe wird durch eine Sprühdose gelöst, die die Merkmale des Anspruchs 1 aufweist. This object is achieved by a spray can, which has the features of claim 1 having.
Durch diese konstruktive Ausgestaltung ist es nun möglich, die Kappe so weit arretiert zu halten, daß ein unbeabsichtigtes Verdrehen praktisch ausgeschlossen ist.With this design, it is now possible to lock the cap so far to maintain that an unintentional twisting is practically impossible.
In einigen Anwendungsfällen besteht die Forderung, daß die Kappe in einer bestimmten Position verharrt, beispielsweise dann, wenn die Kappe die Basis für ein zusätzliches Bauteil bildet, das aufgesetzt ist, mit dem Ventil verbunden und gegenüber der Kappe verdrehbar ist.In some applications there is a requirement that the cap be in a particular Position persists, for example when the cap is the base for one forms additional component that is attached, connected to the valve and opposite the cap is rotatable.
Da in diesem Fall die Kappe sich nicht mitdrehen darf, bietet die Erfindung hierfür eine besonders einfache Lösung.Since the cap must not rotate in this case, the invention offers this a particularly simple solution.
Nach einem Gedanken der Erfindung ist vorgesehen, daß die Unterkante des umlaufenden Kragens mit Zacken versehen ist, die sich in einem Steg eingraben, der an der Kappe angeformt ist und beim Aufsetzen auf den Ventilteller an der Unterkante des Kragens anliegt.According to an idea of the invention it is provided that the lower edge of the circumferential Collar is provided with serrations, which dig into a web, which on the Cap is formed and when placed on the valve plate on the lower edge of the Collar.
Da die Kappe üblicherweise aus Kunststoff besteht, während der Ventilteller aus Metall ist, graben sich die Spitzen der Zacken in das weichere Material der Kappe ein, so daß hierdurch eine ausreichende Verdrehsicherung der Kappe gewährleistet ist.Since the cap is usually made of plastic, while the valve plate is made of metal the tips of the prongs dig into the softer material of the cap, so that this ensures that the cap is adequately secured against rotation.
Ein weiterer Gedanke der Erfindung sieht vor, daß der Kragen außenseitig mit einer Vielzahl von abständig zueinander angeordneten, nach außen gestülpten Nocken versehen ist, die sich beim Aufstecken der Kappe in deren Seitenwandung eingraben und so gleichfalls in eine Verdrehsicherung bilden. Diese Art der Ausformung hat den Vorteil, daß die bereits lackierte Oberfläche nicht beschädigt wird. Überdies ist die Beanspruchung der Formwerkzeuge sehr gering.Another idea of the invention provides that the collar with an outside Provide a plurality of cams which are arranged at a distance from one another and are turned outwards is, which dig into the side wall when the cap is attached and thus also form an anti-rotation device. This type of formation has the Advantage that the already painted surface is not damaged. Moreover, that is Very little strain on the molds.
Dabei können die Nocken länglich ausgebildet sein, und sich in Längsachsrichtung der Sprühdose erstrecken. The cams can be elongated, and in the longitudinal axis direction the spray can.
Auch eine Kombination von Zacken und Nocken ist denkbar. Ebenso eine Rändelung der Außenseite des Kragens.A combination of teeth and cams is also conceivable. Knurling also the outside of the collar.
Ferner kann vorgesehen sein, daß die dem Tellerdom zugewandte Innenseite des Kragens mit Nocken versehen ist, an denen ein Kappenteil anliegt.It can further be provided that the inside of the collar facing the plate dome is provided with cams on which a cap part rests.
Ein besonders fester Formschluß ergibt sich, wenn der Kragen außen- und innenseitig mit Nocken versehen ist.A particularly firm form fit results when the collar is on the outside and inside is provided with cams.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are characterized in the subclaims.
Ausführungsbeispiele der Erfindung werden nachfolgend anhand der beigefügten Zeichnung beschrieben.Embodiments of the invention are described below with reference to the accompanying Drawing described.
Die
- Figur 1
- zeigt zwei Halbschnitte eines Teilausschnitts einer Sprühdose in einer Seitenansicht.
- Figure 1
- shows two half-sections of a partial section of a spray can in a side view.
In der Figur ist ein Ventilteller 1 einer erfindungsgemäßen Sprühdose gezeigt, der einen umlaufenden Kragen 2 aufweist, auf dem eine Kappe 3 aufgesetzt ist.In the figure, a valve plate 1 of a spray can according to the invention is shown, the one encircling collar 2, on which a cap 3 is placed.
Diese stützt sich mit ihrer Wandung an der Außenseite des Kragens 2 ab, wobei die Kappe 3 an ihrer freien Kante einen Auflagesteg 6 aufweist, der sich an der Unterkante des Kragens 2 abstützt.This is supported with its wall on the outside of the collar 2, the Cap 3 has on its free edge a support web 6, which is located on the lower edge of the collar 2 supports.
Bei dem im linken Halbschnitt gezeigten Ausführungsbeispiel ist die Unterkante des Kragens 2 mit sich über den gesamten Umfang erstreckenden Zacken 5 versehen, die sich aufgrund der unterschiedlichen Härten des aus Metall bestehenden Kragens 2 und der aus Kunststoff gebildeten Kappe 3 in den Auflagesteg 6 eingraben.In the embodiment shown in the left half section, the lower edge of the Collar 2 provided with tines 5 extending over the entire circumference, the due to the different hardness of the metal collar 2 and dig the plastic cap 3 into the support web 6.
Der rechtseitige Halbschnitt zeigt eine Ausbildung des Kragens 2, bei der umlaufend Nocken 4 ausgeprägt sind, die sich nach außen hin zur Wandung der Kappe 3 erstrekken.The right half-section shows an embodiment of the collar 2, in the circumferential Cams 4 are pronounced, which extend outwards to the wall of the cap 3.
Dabei sind die Nocken 4 stegartig ausgebildet und in Mittenachsrichtung des Ventiltellers verlaufend.The cams 4 are web-like and in the central axis direction of the valve disk Gradient.
Im gezeigten Ausführungsbeispiel beginnen die Nocken 4 mit Ihrem Verlauf direkt an
der Unterkante des Kragens, so daß in diesem Bereich eine gewisse scharfkantige
Ausbildung entsteht, durch die eine besonders innige Verzahnung der Nocken 4 mit
der aufgesetzten Kappe 3 erreicht wird.
Anstelle der gezeigten Ausführung der Nocken 4 sind selbstverständlich auch andere
geeignete Ausformungen denkbar, beispielsweise in Form von ausgestülpten Löchern,
die umlaufend einen kleinen, scharfkantigen Kragen aufweisen, der sich gleichfalls in
das elastische Material der Kappe 3 eingräbt.In the exemplary embodiment shown, the cams 4 begin their course directly at the lower edge of the collar, so that a certain sharp-edged design is created in this area, through which a particularly intimate interlocking of the cams 4 with the attached cap 3 is achieved.
Instead of the embodiment of the cams 4 shown, other suitable shapes are of course also conceivable, for example in the form of protruding holes which have a small, sharp-edged collar all around, which likewise digs into the elastic material of the cap 3.
