- Two pressure pieces are provided at a distance from the projection in order to open the closure strips when the slide is moved in one direction and to close them in the opposite direction.
- the disadvantage of this closure device is that the user hardly recognizes when the slide is in the middle position whether the closure strips are open or closed, because the distance between the closure strips is very small both in the open and in the closed position and can hardly be seen with the eye can be recognized, which makes handling difficult.
- the sealing of the closure strips is inadequate and, especially with liquids in the bag, leaks can occur.
- FR 2 785 259 discloses a bag with closure strips which are opened and closed via a slide.
- the slide engages around the closure strips and has a separating web which protrudes between the closure strips and is triangular.
- the closure device comprises on the slide on a connecting section a projection for opening the closure strips, which when viewed from above on the connecting section is wedge-shaped Has section with two spreading side walls.
- the opening width can be widened by the wedge-shaped contour, so that the user can see which side is the opening side and which is the closing side by looking at the closure strips on opposite sides of the slide.
- the projection has a greatest width of more than 1.5 mm.
- the projection preferably has a width of more than 1.7 mm on the side opposite a tip, for example between 1.8 mm to 2.5 mm.
- the projection has a length in the sliding direction of more than 3 mm, for example between 4 mm and 6 mm.
- a section of the projection can taper to a point in the shape of a wedge and, when moving with gentle pressure, open the profile strips.
- pressure pieces are preferably provided, which are arranged less than 4 mm, in particular between 1 mm to 3 mm, in the sliding direction. These pressure pieces rest on the outside of the profile strips and press them together during a sliding movement in the closing direction, the short distance from the projection ensuring a good seal.
- the slide In the transition area between the open and closed position, the slide can cause the profile strips to rest as positively as possible via the projection with small gaps, so that the seal against liquids is improved.
- the connecting section can also cover any gaps if the projection is provided within the connecting section when viewed from above.
- the projection has a trapezoidal section with side walls converging towards the end.
- the projection is approximately diamond-shaped in plan view and can be dispensed onto the closure strips from both sides during assembly.
- the side walls of the trapezoidal section can be less pointed than the side walls of the wedge-shaped section.
- the pressure pieces have a length in a direction perpendicular to the plane of the connecting section, according to the invention, which is at least 1.5 times, preferably at least twice as long as the length of the projection. This means that even wide closure strips can be closed reliably.
- two webs are provided, in particular at opposite ends in the slide direction, which protrude inward and are guided along strips of the closure strips.
- the handling of the closure device is further simplified if at least one marking for indicating the opening or closing direction is attached to the slide.

Description
Die vorliegende Erfindung betrifft eine Verschlusseinrichtung für einen Beutel nach dem Oberbegriff des Anspruches 1.The present invention relates to a closure device for a bag according to the preamble of
Die
Weitere Verschlussvorrichtungen mit verriegelbaren Profilstreifen für Beutel und einem Schieber zeigen
Es ist daher Aufgabe der vorliegenden Erfindung, eine Verschlusseinrichtung für einen Beutel zu schaffen, die eine verbesserte Handhabung und gute Abdichtung ermöglicht.It is therefore the object of the present invention to create a closure device for a bag which enables improved handling and good sealing.
Diese Aufgabe wird mit einer Verschlusseinrichtung mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with a closure device having the features of
Die erfindungsgemäße Verschlusseinrichtung umfasst an dem Schieber an einem Verbindungsabschnitt einen Vorsprung zum Öffnen der Verschlussstreifen, der in Draufsicht auf den Verbindungsabschnitt gesehen einen keilförmigen Abschnitt mit zwei aufspreizenden Seitenwänden aufweist. Dadurch können sich die Verschlussstreifen an den Vorsprung besser anlegen, was zu geringeren Spalten und somit zu einer verbesserten Abdichtung führt. Zudem kann die Öffnungsweite durch die keilförmige Kontur verbreitert werden, so dass der Benutzer durch eine Ansicht der Verschlussstreifen auf gegenüberliegenden Seiten des Schiebers erkennt, welche Seite die Öffnungsseite und welche die Verschlussseite ist. Der Vorsprung weist in Draufsicht dabei eine größte Breite von mehr als 1,5 mm auf.The closure device according to the invention comprises on the slide on a connecting section a projection for opening the closure strips, which when viewed from above on the connecting section is wedge-shaped Has section with two spreading side walls. As a result, the closure strips can better fit against the projection, which leads to fewer gaps and thus to an improved seal. In addition, the opening width can be widened by the wedge-shaped contour, so that the user can see which side is the opening side and which is the closing side by looking at the closure strips on opposite sides of the slide. In a plan view, the projection has a greatest width of more than 1.5 mm.
Vorzugsweise weist der Vorsprung auf der zu einer Spitze gegenüberliegenden Seite eine Breite von mehr als 1,7 mm auf, beispielsweise zwischen 1,8 mm bis 2,5 mm. Dadurch werden die Verschlussstreifen auf der Öffnungsseite in einem Abstand von rund 2 mm gehalten, was mit dem Auge erkennbar ist und somit die Handhabung gegenüber vorbekannten Schiebern verbessert, bei denen die Verschlussstreifen nur um etwa 1 mm geöffnet werden.The projection preferably has a width of more than 1.7 mm on the side opposite a tip, for example between 1.8 mm to 2.5 mm. As a result, the closure strips are kept at a distance of around 2 mm on the opening side, which can be seen with the eye and thus improves handling compared to previously known slides in which the closure strips are only opened by around 1 mm.
In einer weiteren Ausgestaltung besitzt der Vorsprung eine Länge in Schieberichtung von mehr als 3 mm, beispielsweise zwischen 4 mm und 6 mm. Dadurch kann der Vorsprung mit einem Abschnitt keilförmig spitz zulaufen und bei einer Bewegung mit sanftem Druck die Profilstreifen öffnen. Beabstandet von der Spitze des Vorsprunges sind vorzugsweise Druckstücke vorgesehen, die in Schieberichtung weniger als 4 mm, insbesondere zwischen 1 mm bis 3 mm, angeordnet sind. Diese Druckstücke liegen außen an den Profilstreifen an und drücken diese bei einer Schiebebewegung in Schließrichtung zusammen, wobei der kurze Abstand zu dem Vorsprung für eine gute Abdichtung sorgt. Im Übergangsbereich zwischen Öffnungs- und Schließposition kann der Schieber über den Vorsprung ein möglichst formschlüssiges Anliegen der Profilstreifen bewirken mit geringen Spalten, so dass die Abdichtung gegenüber Flüssigkeiten verbessert ist. Zudem kann auch der Verbindungsabschnitt etwaige Spalte überdecken, wenn der Vorsprung in Draufsicht gesehen innerhalb des Verbindungsabschnittes vorgesehen ist.In a further embodiment, the projection has a length in the sliding direction of more than 3 mm, for example between 4 mm and 6 mm. As a result, a section of the projection can taper to a point in the shape of a wedge and, when moving with gentle pressure, open the profile strips. At a distance from the tip of the projection, pressure pieces are preferably provided, which are arranged less than 4 mm, in particular between 1 mm to 3 mm, in the sliding direction. These pressure pieces rest on the outside of the profile strips and press them together during a sliding movement in the closing direction, the short distance from the projection ensuring a good seal. In the transition area between the open and closed position, the slide can cause the profile strips to rest as positively as possible via the projection with small gaps, so that the seal against liquids is improved. In addition, the connecting section can also cover any gaps if the projection is provided within the connecting section when viewed from above.
Der Vorsprung weist erfindungsgemäß in Draufsicht gesehen einen trapezförmigen Abschnitt mit zum Ende zusammenlaufenden Seitenwänden auf.According to the invention, seen in plan view, the projection has a trapezoidal section with side walls converging towards the end.
Dadurch ist der Vorsprung in Draufsicht annähernd rautenförmig und kann bei der Montage auf die Verschlussstreifen von beiden Seiten aufgespendet werden. Die Seitenwände des trapezförmigen Abschnittes können dabei weniger spitz zulaufen als die Seitenwände des keilförmigen Abschnittes.As a result, the projection is approximately diamond-shaped in plan view and can be dispensed onto the closure strips from both sides during assembly. The side walls of the trapezoidal section can be less pointed than the side walls of the wedge-shaped section.
Für ein zuverlässiges Verschließen der Verschlussstreifen weisen die Druckstücke in eine Richtung senkrecht zu der Ebene des Verbindungsabschnittes erfindungsgemäß eine Länge auf, die mindestens 1,5mal, vorzugsweise mindestens doppelt so lang ist wie die Länge des Vorsprunges. Dadurch können auch breite Verschlussstreifen zuverlässig geschlossen werden.For reliable closing of the closure strips, the pressure pieces have a length in a direction perpendicular to the plane of the connecting section, according to the invention, which is at least 1.5 times, preferably at least twice as long as the length of the projection. This means that even wide closure strips can be closed reliably.
An den Seitenwänden des Schiebers sind jeweils zwei Stege vorgesehen, insbesondere an gegenüberliegenden Enden in Schieberichtung, die nach innen ragen und entlang von Leisten der Verschlussstreifen geführt sind. Dadurch ist der Schieber gegen ein Anheben von den Verschlussstreifen gesichert, und zudem wird eine exakte Führung in eine Richtung senkrecht zur Schieberichtung gewährleistet.On the side walls of the slide, two webs are provided, in particular at opposite ends in the slide direction, which protrude inward and are guided along strips of the closure strips. As a result, the slide is secured against being lifted off the closure strip, and precise guidance in a direction perpendicular to the slide direction is also ensured.
Die Handhabung der Verschlusseinrichtung wird weiter vereinfacht, wenn an dem Schieber mindestens eine Markierung zur Anzeige der Öffnungs- oder Schließrichtung angebracht ist. Eine entsprechende Markierung kann als Pfeil, Piktogramm oder Test vorgesehen sein.The handling of the closure device is further simplified if at least one marking for indicating the opening or closing direction is attached to the slide. A corresponding marking can be provided as an arrow, pictogram or test.
Die Verschlusseinrichtung ist vorzugsweise an einem Beutel zur Aufbewahrung von Lebensmitteln vorgesehen, insbesondere aus einer transparenten Kunststofffolie.The closure device is preferably provided on a bag for storing food, in particular made of a transparent plastic film.

Hierfür werden die hakenförmigen Profilstreifen 10 und 11 zueinander gedrückt und können durch die Hakenform aneinander verrasten. An dem Verschlussstreifen 4 ist noch ein nach innen ragender Führungsstreifen 12 ausgebildet, der verhindert, dass der obere hakenförmige Profilstreifen 10 an dem Verschlussstreifen 5 nach oben ausweichen kann. Dadurch sind beide Profilstreifen 10 formschlüssig an den beiden Profilstreifen 11 verrastbar. Es können natürlich auch andere Geometrien für die Profilstreifen 10 und 11 eingesetzt werden, um diese lösbar miteinander zu verbinden.The closure strip 4 comprises two hook-shaped profile strips 11 which can be brought into engagement with two hook-shaped profile strips 10 on the
Um die Profilstreifen 10 und 11 zu entriegeln und den Beutel 1 zu öffnen, ist an dem Verbindungsabschnitt 19 ein Vorsprung 20 angeformt, der zumindest teilweise zwischen die beiden Verschlussstreifen 4 und 5 eingreift, insbesondere oberhalb der Profilstreifen 10 und 11. Durch den Vorsprung 20 können die Verschlussstreifen 4 und 5 auseinander gedrückt werden, um diese bei Bewegung des Schiebers 6 in Öffnungsrichtung zu öffnen.
