Die Federzungen 20 laufen von der Deckenwand 12 weg, im unbeladenen Zustand der Schutzhaube 10, vorzugsweise aufeinander zu. Daher formen die Kanten der Deckenwand 12 und der Federzungen 20 mit den Führungszungen 22, welche zusammen die Einschuböffnung 11 bilden, im unbeladenen Zustand der Schutzhaube 10 vorzugsweise zumindest annähernd ein Trapez, wobei die einander gegenüberliegenden freien Enden der Führungszungen 22 in einem geringen Abstand zueinander angeordnet sind, oder sich gegebenenfalls berühren. Dieser geometrische Aufbau erlaubt beim Einschieben eines Bürstenkopfes 41 eine gewisse Federkraft der Federzungen 20 auf den Borstenträger 42. Der Winkel zwischen den Seitenwänden 16a, 16b beziehungsweise den Federzungen 20 und der Deckenwand 12 beträgt zwischen 0° und 20° vorzugsweise zwischen 5° und 9°. Der Querschnitt der Einschuböffnung 11 ist symmetrisch oder asymmetrisch gestaltet, vorzugsweise symmetrisch. Der Querschnitt ist demzufolge in der Gestaltung unter Einhaltung der Rahmenbedingungen der Funktionalität und des Entformens frei.The
Die Führung 18 erlaubt eine einfachste Handhabung der Schutzhaube. Einbringen und Entnehmen des Zahnbürstenkopfes geschieht durch eine einfache, lineare Bewegung in beziehungsweise entgegen der Einschubrichtung E, ohne das ein Klappmechanismus oder eine Mechanik bedient werden müssen. Die einzelnen Federzungen 20 liegen aufgrund der mit der geometrischen Form vorgegebenen Federkraft individuell am Borstenträger an.
Die Schlitze 28, die die Federzungen 20 mit den entsprechenden Führungszungen 22 von einander abgrenzen, verlaufen vom freien Ende der Federzungen 20 in Richtung zur Deckenwand 12 hin und enden zum Teil in unterschiedlichen Abständen zur Deckenwand 12. Dadurch lässt sich bei gleicher Wandstärke der Schutzhaube 10 die Federkraft und die elastische Auslenkbarkeit der Federzungen 20 variieren.The
Die Schlitze 28 erlauben weiter eine optimale Luftzirkulation zum Trocknen der Reinigungselemente 43 und / oder des Borstenbesatzes nach dem Gebrauch der Zahnbürste 40.The
Der Borstenträger 42 des Zahnbürstenkopfes 41 der Zahnbürste 40 ist leicht oval geformt. Die Federzungen 20 liegen aufgrund der Federkraft individuell am Borstenträgers 42 an. Daher sind die der Einführungsöffnung 11 zugewandten Federzungen 20 wieder nahezu vollständig in die Ausgangslage der unbeladenen Schutzhaube 10 zurück gefedert und halten den Zahnbürstenkopf 41 zusätzlich in der Schutzhaube fest. Die weiteren Federzungen 20 geben je nach Form des Borstenträgers 42 mehr oder weniger nach und halten den Zahnbürstenkopf 41 mittels Klemmwirkung und Reibkraft fest in der Schutzhaube 10.The
In
Erfindungsgemässe Schutzhauben 10 werden vorzugsweise einstückig aus mindestens einer Hartkomponente geformt, zusätzlich können eine Weichkomponente oder mehrere Weichkomponenten angebracht sein. Aus der Hartkomponente sind vorzugsweise die Deckenwand 12, die Seitenwände 16a, 16b, die Federzungen 20, die Führungszungen 22, die Rippen 26 und die Rückwand 30 geformt.
Als Hartkomponente können insbesondere Hart-Kunststoffe wie zum Beispiel Polypropylen (PP), Polyester (PET), Polycyclohexandimethanoltherasthalat (PCT/PCT-A (säuremodifiziert)/PCT-G (glykolmodifiziert)), Polyethylen (PE), Polystyrol (PS) wie beispielsweise Styrene-Butadiene (SB), Styrolacrylnitril (SAN), Polymethylmethacrylat (PMMA), Acrylbuthadienstyrol (ABS), Polyoxymethylen (POM), oder Polyamid (PA), Polyvinylchlorid (PVC) etc., vorzugsweise Polypropylen (PP) verwendet werden.In particular, hard plastics such as polypropylene (PP), polyester (PET), polycyclohexanedimethanoltherasthalate (PCT / PCT-A (acid-modified) / PCT-G (glycol-modified)), polyethylene (PE), polystyrene (PS) such as Styrene-butadiene (SB), styrene-acrylonitrile (SAN), polymethylmethacrylate (PMMA), acrylobutadiene-styrene (ABS), polyoxymethylene (POM), or polyamide (PA), polyvinylchloride (PVC) etc., preferably polypropylene (PP).
Als weiches Material bzw. Weichkomponente können insbesondere Weich-Kunststoffe wie zum Beispiel low density Polyethylen (PE-LD), high density Polyethylen (PE-HD), Polyethylen (PE), Polyvinylchlorid (PVC), gummielastischer Werkstoff wie Polyurethan (PUR), thermoplastisches Elastomer (TPE), Polyolefin basiertes Elastomer etc. vorzugsweise ein thermoplastisches Elastomer (TPE) verwendet werden. Die Shore A Härten des Weich-Kunststoffes liegen vorzugsweise unter 90.As a soft material or soft component in particular soft plastics such as low density polyethylene (PE-LD), high density polyethylene (PE-HD), polyethylene (PE), polyvinyl chloride (PVC), rubber-elastic material such as polyurethane (PUR), thermoplastic elastomer (TPE), polyolefin-based elastomer, etc., preferably a thermoplastic elastomer (TPE) may be used. The Shore A hardnesses of the plastic are preferably below 90.
Das Anbringen von verschiedenen Komponenten in der Schutzhaube 10 passiert vorzugsweise mittels Spritzgiessen. Die verschiedenen Komponenten können jeweils nur auf der Innenseite, nur auf der Aussenseite oder auf beiden Seiten vorhanden, bzw. angespritzt sein. Die jeweils gewünschte Funktion der weiteren Komponente wird durch diese Anordnung bestimmt. Beispielsweise bringt auf der Innenseite angebrachte Weichkomponente eine Verminderung des Abrutschens der Schutzhaube 10 vom Zahnbürstenkopf 41, eine Weichkomponente auf der Aussenseite verbessert die Griffigkeit, bezw. Haptik für die menschliche Hand bei der Manipulation.The attachment of various components in the
Die Herstellung der Schutzhaube 10 passiert vorzugsweise mittels günstigem und einfachem Spritzgiessens in einer Spritzgiessform.The production of the
Die Wandstärke der Schutzhaube 10 beziehungsweise der einzelnen Komponenten ist vorzugsweise im Wesentlichen konstant, was eine optimierte Zykluszeit erlaubt und die Qualität des Endprodukts verbessert da Lunker oder Einfallstellen vermieden werden können.The wall thickness of the
Die Seitenwände 16a und 16b, die Federzungen 20, die Führungszungen 22, die Deckenwand 12 und die Rückwand 30 weisen vorzugsweise eine wenigstens annähernd konstante Wandstärke von vorzugsweise 0.5mm bis 1.5mm, insbesondere von 0.7mm bis 1mm, auf.The
Die Herstellung der Schutzhaube 10 erfolgt in einem Spritzguss-Werkzeug mit Schiebern und einem Kern. Zur Entformung wird als erstes das Werkzeug in Richtung der Einschubrichtung E der Schutzhaube geöffnet. Die Formtrennung liegt hierbei im Übergangsbereich der Schutzhaube 10 von den elastischen Seitenwänden 16a, 16b zur Rückseite 30. Parallel dazu erfolgt die Entformung der Federzungen 20 senkrecht zur ersten Bewegungsrichtung und senkrecht zur Deckenwand 12 der Schutzhaube 10. Die Formtrennung liegt in diesem Fall im Übergang von den Seitenwänden 16a, 16b zur Deckenwand 12 der Schutzhaube 10. Nach Abschluß dieser beiden Entformungen wird der Kern, der den Hohlraum in der Schutzhaube 10 für das Einbringen des Zahnbürstenkopfes 41 formt, gezogen. Hierbei werden die Führungsrippen 26 mit den Führungsschultern 24 mindestens teilweise zwangsentformt. Nach diesen Schritten ist die Schutzhaube 10 komplett entformt.The production of the
Die Federzungen 20 sind, in Einschubrichtung E gemessen, zwischen 2mm bis 10mm, vorzugsweise zwischen 4mm bis 7.5mm, breit, sie können in der Breite konstant sein oder über den angegebenen Bereich variieren.The
Die elastischen Seitenwände 16a, 16b werden vorzugsweise durch zwei bis zehn, insbesondere drei bis sieben Federzungen 20 gebildet. Die Bestückung erfolgt symmetrisch oder asymmetrisch, vorzugsweise asymmetrisch.The
In einer nicht gezeigten Ausführungsform trägt die Führung 18 zumindest teilweise einen weichelastischen Belag, der die Reibkraft zwischen Führung 18 und Borstenträger 42 erhöht und somit den Zahnbürstenkopf 41 noch sicherer in der Schutzhaube 10 hält. Dadurch kann die Möglichkeit, dass die Schutzhaube 10 beispielsweise durch Vibrationen vom Kopf abrutscht, vermindert werden. Ebenfalls ist es möglich die Führungsrippen 26 mindestens teilweise mit einem weichelastischen Belag zu versehen oder diese mindestens teilweise komplett aus Weichmaterial herzustellen.In one embodiment, not shown, the guide 18 at least partially carries a soft-elastic coating, which increases the frictional force between the guide 18 and bristle
Die Schlitze 28, 29 zwischen den Federzungen 20 und Führungszungen 22 könne zumindest teilweise mit einem bezüglich der restlichen Schutzhaube 10 weicheren Kunststoff gefüllt sein. Das Füllen der Schlitze 28, 29 mit Weichkomponente bringt einen zusätzlichen Einstellparameter für die Flexibilität der Federarme. In diesem Fall wie auch in allen anderen angegebenen Ausführungsarten der Schlitze können diese innerhalb der Schutzhaube 10 variieren, das heisst, es müssen nicht alle gleich ausgestaltet sein.The
Die Schlitze 29 können vor dem ersten Einführen eines Zahnbürstenkopfs 41 in die Schutzhaube 10 auch über Stege aus Hart- oder Weichmaterial mit einem Durchmesser von unter 1mm vorzugsweise von unter 0.5mm miteinander verbunden sein. Die Ausführung ist in diesem Fall so, dass diese Stege beim ersten Gebrauch der Schutzhaube 10 reissen und den Gebrauch als Schutzhabe ermöglichen. Die Stege bilden somit einen zuverlässigen Neuheitsindikator der Schutzhaube 10. Zusätzlich sind verbundene Führungszungen 22 für das Handling während dem Verarbeitungsprozess besser, wenn die Schutzhauben 10 als Schüttgut aufbewahrt und gefördert werden, verharken sie durch die Verbindung weniger und die Produktionssicherheit steigt.The
In einer weiteren nicht gezeigten Ausführungsform der Schutzhaube 10 können die Schlitze 28, 29 auch unterbrochen ausgeformt sein. Dabei können sich die oben erwähnten, in diesem Fall vorzugsweise aus weichem Material bestehenden Stege flexibel ausdehnen, ohne im weiteren Gebrauch zu reissen, d.h. es besteht eine flexible Verbindung der Federzungen über den Schlitz 29 hinweg.In a further embodiment, not shown, of the
Bei einer weiteren nicht gezeigten Ausführungsform wird die Führung 18 durch zwei im Endbereich der Federzungen 20 ausgebildeten Führungsrippen 26 bereitgestellt. Die Führungsrippen 26 sind einerseits von den Führungszungen 22 und andererseits voneinander beabstandet und bilden sich gegenüberliegende Führungsschultern 24. Dadurch wird der Borstenträger 42 weiter im Inneren der Schutzhaube 10 zwischen den Führungsrippen 26 geführt und gehalten. Damit werden an der Unterseite 44 des Borstenträgers 42 angebrachte vorstehende Elemente, beispielsweise Zungenreiniger, geschützt und von den Führungszungen 22 beabstandet und zumindest teilweise überdeckt in der Schutzhaube 10 gehalten.In another embodiment, not shown, the guide 18 is provided by two
Die Schutzhaube 10 hat entlang der Einschubrichtung E eine Länge von 15mm bis 45mm vorzugsweise 29mm bis 40mm. Die Breite entlang der Deckenwand 10 gemessen, beträgt zwischen 10mm und 25mm vorzugsweise zwischen 12mm und 20mm. Die Höhe zwischen der Deckenwand 10 und den Führungszungen 22 beträgt zwischen 15mm und 30mm vorzugsweise zwischen 17mm und 27mm.The
Die erfindungsgemässe Schutzhaube 10 für Zahnbürsten kann analog für jegliche Arten von Zahnbürsten, sowohl für elektrische und auch manuelle Zahnbürsten oder andere Dentalreinigungsgeräte mit einem Behandlungs- bezw. einem Reinigungskopf verwendet werden. Dabei kann der Behandlungskopf bzw. die Reinigungselemente auch in Richtung der Einschubrichtung E vom Reinigungsgerät abstehen.The
Je nach spezifischer Ausgestaltungsvariante sind Anpassungen beispielsweise in Grösse, geometrischer Grundform und Federzungen-Anzahl nötig. So ist beispielsweise für den Bürstenkopf einer oszillierenden Elektro-Zahnbürste die Schutzhaube 10 in ihren Dimensionen Länge, Breite zu verkleinern und allenfalls die Federzungen-Breite zu minimieren und die Anzahl der Federzungen zu erhöhen.Depending on the specific embodiment variant adjustments, for example, in size, geometric shape and number of spring tongues are necessary. Thus, for example, for the brush head of an oscillating electric toothbrush, the
Selbstverständlich sind die in dieser Schrift gezeigten Ausgestaltungsvarianten beispielhaft. Die einzelnen Ausprägungen und Elemente dieser Ausgestaltungsvarianten können mit anderen Ausgestaltungsvarianten kombiniert werden ohne den Rahmen dieser Erfindung zu verlassen.Of course, the design variants shown in this document are exemplary. The individual forms and elements of these design variants can be combined with other design variants without departing from the scope of this invention.
