Description
Gegenstand der Erfindung ist ein Foliendispenser gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a film dispenser according to the preamble of
Aufgerollte Folien wie z.B. Adhäsionsfolien, die in privaten Haushalten oder im Gastrobereich genutzt werden, sind oft in Gebinden aus Karton oder Wellpappe gelagert. In der Regel sind solche Gebinde zugleich auch als Dispenser ausgebildet, aus denen Folienabschnitte herausgezogen und mittels einer Trennvorrichtung abgetrennt werden können.Rolled films such as e.g. Adhesion films used in private households or in the catering industry are often stored in cardboard or corrugated cardboard containers. As a rule, such containers are at the same time also designed as dispensers, from which film sections can be pulled out and separated by means of a separating device.
Aus der Patentanmeldung
Zum Anbringen der Schneidvorrichtung an der Längswand beim Führungsspalt kann die Schneidvorrichtung zweiteilig ausgebildet sein, wobei der Fussteil von innen her mittels einer Schnappverbindung am Hals befestigt wird, nachdem dieser von aussen her durch den Führungsspalt an der Längswand eingeführt worden ist. Die Herstellung und das Zusammenfügen solcher Schneidvorrichtungen unmittelbar am Gehäuse sind kompliziert und teuer.For attaching the cutting device to the longitudinal wall at the guide gap, the cutting device may be formed in two parts, wherein the foot part is fastened from the inside by means of a snap connection on the neck, after this from the outside through the guide gap on the Longitudinal wall has been introduced. The manufacture and assembly of such cutting devices directly on the housing are complicated and expensive.
Alternativ kann der Längsspalt an einem seiner Enden eine grössere Öffnung zum Einführen der Schneidvorrichtung umfassen. Dies erfordert unnötig lange Gehäuselängen und birgt zudem die Gefahr, dass Schneidvorrichtungen im Bereich der Öffnungen aus der Führung springen und verloren gehen.Alternatively, the longitudinal gap at one of its ends may comprise a larger opening for insertion of the cutting device. This requires unnecessarily long housing lengths and also entails the risk that cutting devices in the region of the openings jump out of the guide and get lost.

In den
Die Schneidvorrichtung 1 umfasst weiter ein erstes Führungsorgan 7 mit einer parallel zum Gleitabschnitt 3b angeordneten ersten Führungsplatte 7a. Die Länge L3 und die Breite B3 der ersten Führungsplatte 7a sind ähnlich oder geringfügig grösser als jene der Gleitsohle 3a des Kopfteils 3. Vorzugsweise überragt die Führungsplatte 7a die Gleitsohle 3a in Schneidrichtung S bzw. Längsrichtung und quer dazu um etwa einen bis zwei Millimeter auf jeder der Seiten.The
Der erste Halsabschnitt 5 dient als Stütze oder Abstandshalter, der den Kopfteil 3 und das erste Führungsorgan 7 vorzugsweise in der Mitte der Gleitsohle 3a und der ersten Führungsplatte 7a miteinander verbindet und diese Teile beabstandet zueinander hält.The
Die erste Führungsplatte 7a begrenzt zusammen mit der Gleitsohle 3a einen ersten Führungsraum, der im Bereich des Gleitabschnitts 3b eine Höhe H1 aufweist, die vorzugsweise im Bereich von 1 mm bis 5 mm liegt und beispielsweise 2 mm beträgt.The
In Schneidrichtung S nimmt die Länge L2 des ersten Halsabschnitts 5 ausgehend von einer Länge L2" beim ersten Führungsorgan 7 bis zu einer Länge L2' beim Kopfteil 3 zu. Die Zunahme der Länge L2 kann eine lineare oder vorzugsweise progressive Funktion der Höhenlage über der ersten Führungsplatte 7a sein. In den ersten Halsabschnitt 5 ist eine Klinge 9 eingebettet, die vorzugsweise eine umgekehrte Trapezform aufweist. Mindestens einer, vorzugsweise beide Schenkel der Klinge 9 sind als geschärfte Schneidkanten 9a ausgebildet und ragen in Schneidrichtung S über den ersten Halsabschnitt 5 hinaus. In den Austrittsbereichen der Klinge 9 ist der erste Halsabschnitt 5 angefast, sodass sich seine Breite B2 zur Klinge 9 hin verringert.In the cutting direction S, the length L2 of the
An der ersten Führungsplatte 7a ragen vorzugsweise entlang der beiden Längskanten Kontaktelemente 7b nach oben, deren Höhe etwas kleiner ist als die Höhe H1 des ersten Führungsraums. Der Höhenunterschied zwischen dem Niveau der Unterseite der Gleitsohle 3a und dem Niveau der Oberkanten der Kontaktelemente 7b ist so bemessen, dass er zumindest näherungsweise der Materialstärke der an den ersten Führungsspalt 53 angrenzenden Abschnitte der Faltschachtel 51 einschliesslich eines daran anliegenden Folienabschnitts (nicht dargestellt) entspricht. Dies bewirkt, dass der Bewegungsspielraum der Schneidvorrichtung 1 orthogonal zur Ebene der Führungsplatte 7a, also in Halsrichtung, beschränkt wird. Der Gleitabschnitt 3b ist deshalb an der Aussenwand bzw. der äusseren Führungswand 55 der Faltschachtel 51 oder an einem dort anliegenden Folienabschnitt anliegend gehalten. Das Spiel für Bewegungen der Schneidvorrichtung 1 in Halsrichtung, d.h. orthogonal zur äusseren Führungswand 55, ist minimal. Die Schneidvorrichtung 1 kann jedoch leichtgängig entlang des ersten Führungsspalts 53 verschoben werden. Dabei wird der zu trennende Folienabschnitt durch den in Schneidrichtung S vorderen hochgebogenen Endabschnitt 3c der Gleitsohle 3a mit nur geringem Druck sanft an die den ersten Führungsspalt 53 begrenzenden Abschnitte der äusseren Führungswand 55 angelegt, bevor er von der vorderen Schneidkante 9a in einer definierten Lage durchtrennt wird.At the
Unten an der ersten Führungsplatte 7a ragt ein zweiter Halsabschnitt 15 nach unten, dessen Breite B4 quer zur Schneidrichtung S etwa der Breite eines zweiten Führungsspalts 63 an einer inneren Führungswand 65 der Faltschachtel 51 entspricht (
Wenn die beiden Hälften des Kunststoffkörpers vollständig zusammengeklappt werden, sodass sie aneinander anliegen, greifen die Ausrichtbolzen 21 in die Bolzenaufnahmen 23 ein. Dadurch werden die beiden Hälften des Kunststoffkörpers in einer definierten Lage relativ zueinander gehalten und zugleich die Lage der Klinge 9 in der Trennebene gesichert.When the two halves of the plastic body are completely folded so that they rest against each other, engage the
Analog zu den Ausrichtbolzen 21 und den Bolzenaufnahmen 23 sind an den beiden Hälften des Kunststoffkörpers miteinander korrespondierende Verbindungselemente angeordnet, beispielsweise hervorragende Rastbolzen 31 und vertiefte Rastbolzenaufnahmen 33, welche die beiden zusammengeklappten Hälften des Kunststoffkörpers in der geschlossenen Lage mittels einer form- oder kraftschlüssigen Verbindung sichern.Analogous to the
Die Schutzwand 75 schützt eine im Innern der Faltschachtel 51 gelagerte Folienrolle (nicht dargestellt), damit diese nicht durch die Schneidvorrichtung 1 beschädigt werden kann, wenn diese in Schneidrichtung S verschoben wird. Allgemein sind Ecken und Kanten der Schneidvorrichtung abgerundet. Dies begünstigt das leichtgängige Verschieben der Schneidvorrichtung 1 und trägt ebenfalls dazu bei, dass die Faltschachtel 51 und die Folie beim Verschieben nicht beschädigt werden.The
Die Materialstärke der Faltschachtel 51 liegt vorzugsweise im Bereich von 0.4mm bis 1mm. Dies gilt auch für die Dicken der ersten Führungsplatte 7a und der zweiten Führungsplatte 7b.The material thickness of the
Die innere Führungswand 65 könnte bei alternativen Ausführungsformen der Faltschachtel 51 auch als lose Einlagewand ausgebildet sein.The
Die vergleichsweise geringe Bauhöhe der Schneidvorrichtung 1 ermöglicht eine gute Nutzung des Raums für die von der Faltschachtel 51 aufzunehmende Folienrolle. Dadurch können die vergleichsweise kompakte Faltschachteln 51 hergestellt werden.The comparatively small height of the
Die Führungsspalte 53, 63 müssen nicht zwingend in der Mitte der Führungswände 55, 65 angeordnet sein. Sie können auch zu einer der Längskanten der Führungswände 55, 65 hin versetzt angeordnet sein, wobei sichergestellt werden muss, dass die Schneidvorrichtung 51 ungehindert in Schneidrichtung S verschoben werden kann.The
Die flache Bauweise der Schneidvorrichtung 1, insbesondere der zweiten Führungsplatte 17a stellt sicher, dass selbst bei Foliendispensern ohne Schutzwand 75 eine im Dispenser gelagerte Folienrolle nicht durch die Schneidvorrichtung 1 beschädigt werden kann.The flat design of the
Die innere Führungswand 65 kann an einer oder mehreren Stellen innerhalb der Faltschachtel 51 in ihrer Lage fixiert bzw. gegen unerwünschte Bewegungen in einer oder mehreren Richtungen gesichert sein. Vorzugsweise sind die Breite und optional auch die Länge der zweiten Führungswand 55 so an die Innenmasse der Faltschachtel 51 angepasst, dass Bewegungen der inneren Führungswand 65 in den jeweiligen Richtungen innerhalb der Faltschachtel 51 verhindert werden. Bei einer oder mehreren der langen und/oder kurzen Seitenkanten der inneren Führungswand 65 können optional umgeklappte End-oder Verbindungsabschnitte 59 ausgebildet sein, die als Abstandhalter oder Anschlagelemente zum Vorgeben oder Begrenzen der Lage der inneren Führungswand 65 innerhalb der Faltschachtel 51 genutzt werden können.The
Wenn die Schneidvorrichtung 1 an der Faltschachtel 51 montiert ist, ragt der zweite Halsabschnitt 15 mit geringem Spiel durch den zweiten Führungsspalt 63 weiter ins Innere der Faltschachtel 51. Der zweite Halsabschnitt 15 wirkt demnach als zusätzliches Führungsmittel, das Translationsbewegungen der Schneidvorrichtung 1 quer zur Schneidrichtung S verhindert bzw. begrenzt, in Schneidrichtung S jedoch zulässt. Da die beiden Führungswände 55, 65 und die zugehörigen Halsabschnitte 5, 15 orthogonal beabstandet zueinander angeordnet sind, bewirken sie gemeinsam einen verbesserten Schutz gegen Schwenkbewegungen bzw. unerwünschtem Verkanten der Schneidvorrichtung 1, wenn beispielsweise ein Drehmoment bezüglich der Schneidrichtung S und/oder bezüglich der Halsrichtung auf die Schneidvorrichtung 1 wirkt. Da der zweite Halsabschnitt 15 in Schneidrichtung S über die Schneidkanten 9a hinausragt, steht er beim Verschieben der Schneidvorrichtung 1 in Schneidrichtung S am Ende des zweiten Führungsspalts 63 an der inneren Führungswand 65 an, bevor die Schneidkante 9a auf am Ende des ersten Führungsspalts 53 die äussere Führungswand 55 beschädigen kann.When the
