Abstract
Plastic rubbish bag with an attached closure device for closing the bag opening and formed from strips of heat-weldable material, pref. the same as the bag itself, welded to each other at the longitudinal edges of the bag.
Description
Es ist bekannt an Abfallbeuteln aus Papier oder Kunststoff z.B. aus Polyäthylen ein Verschlussorgan, z.B. ein Band zu befestigen, mit welchem der gefüllte Beutel, nach erfolgtem Zusammenraffen der Öffnung verschlossen werden kann.
Beim erfindungsgemässen Abfallbeutel sind nun unterhalb der Einfüllöffnung z.B. beidseitig der Schlauchbahn des Beutels, Bänder aus schweissbarem Material, z.B. aus dem gleichen Kunststoff, aus welchem der Beutel gebildet ist, angebracht, die an den Längsrändern des Beutels mit demselben verschweisst sind. Beim Gebrauch des Verschlussorgans können z.B. zwei Bänder eines Beutels in der Nähe des einen Längsrandes durchschnitten werden, so dass sie nur noch beim anderen Längsrand mit dem Beutel verbunden sind. Die beiden freien Enden lassen sich dann um die zusammengeraffte Öffnung schlingen und verknüpfen.
Der erwähnte Beutel lässt sich auf sehr wirtschaftliche Weise herstellen, indem es möglich ist, den Beutel, zusammen mit dem daran befestigten Verschlussorgan in einem Arbeitsgang herzustellen. Das erfindungsgemässe Verfahren zur Herstellung des Beutels ist dadurch gekennzeichnet, dass unterhalb und oberhalb der Schlauchbahn des Beutels quer zu derselben verlaufende Bänder aus verschweissbarem Material verlaufen, die anlässlich der Bildung der Längsränder mit denselben verschweisst werden.
In der Zeichnung ist eine beispielsweise Ausführungsform eines Abfallbeutels mit Verschlussorgan gemäss der Erfindung dargestellt. Der dargestellte Beutel besteht aus einer Kunststoffolie, z.B. aus durchsichtigem Polyäthylen, die längs der Bodenkante 1 gefaltet und längs ihren Längsrändern 2, 3 verschweisst ist. Unterhalb der Beutelöffnung 4 sind zwei Bänder 5, 6, zweckmässig ebenfalls aus Polyäthylen quer zur Längsrichtung des Beutels angeordnet, die an den Längsrändern 2, 3 mit der den Beutel bildenden Folie verschweisst sind. Zum Verschliessen des gefüllten Beutels werden die Bänder 5, 6 in der Nähe der einen Schweissnaht durchschnitten, während sie mit der anderen Schweissnaht nach wie vor verbunden sind. Die freien Enden der beiden Bänder können dann um die zusammengeraffte Beutelöffnung geschlungen und miteinander verknüpft werden.
Die Herstellung des beschriebenen Beutels einschliesslich des daran angebrachten Verschlussorgans erfolgt in einem Arbeitsgang. Hierbei wird auf einer handelsüblichen Beutelmaschine für grosse Kunststoff-Beutel eine Vorrichtung zur Aufnahme von zwei z.B. etwa 4 cm breiten Rollen geschaffen.
Je ein endloses Band läuft von unten und von oben auf die in der Beutelmaschine durchlaufende Schlauchbahn des Beutels.
Zusammen mit der letzteren werden die Bänder in die Schweissstation eingeführt. Hier wird die Schlauchbahn mittels Trennahtschweissung getrennt. Dabei entstehen die einzelnen Beutel und die beiden Bänder 5, 6 werden gleichzeitig seitlich angeschweisst und vom endlosen Band getrennt.
PATENTANSPRUCHE
I. Abfallbeutel aus Kunststoff, mit einem daran befestigten Verschlussorgan zum Verschliessen der Beutelöffnung, dadurch gekennzeichnet, dass das Verschlussorgan durch unterhalb der Einfüllöffnung angeordnete Bänder aus schweissbarem Material gebildet ist, die an den Längsrändern des Beutels mit demselben verschweisst sind.
II. Verfahren zur Herstellung des Abfallbeutels nach Patentanspruch I, bei welchem die Längsränder desselben durch Verschweissen einer Kunststoffolie gebildet werden, dadurch gekennzeichnet, dass unterhalb und oberhalb der Schlauchbahn des Beutels quer zu derselben verlaufende Bänder aus verschweissbarem Material verlaufen, die anlässlich der Bildung der Längsränder mit denselben verschweisst werden.
**WARNUNG** Ende DESC Feld konnte Anfang CLMS uberlappen**.
It is known on paper or plastic waste bags e.g. a closure member made of polyethylene, e.g. to attach a tape with which the filled bag can be closed after the opening has been gathered together.
In the case of the waste bag according to the invention, e.g. on both sides of the tubular web of the bag, tapes made of weldable material, e.g. made of the same plastic from which the bag is formed, attached, which are welded to the same at the longitudinal edges of the bag. When using the closure member, e.g. two straps of a bag are cut in the vicinity of one longitudinal edge so that they are only connected to the bag at the other longitudinal edge. The two free ends can then be looped around the gathered opening and linked.
The aforementioned bag can be manufactured in a very economical manner in that it is possible to manufacture the bag together with the closure element attached to it in one operation. The method according to the invention for producing the bag is characterized in that strips of weldable material running transversely to the same run underneath and above the tubular path of the bag, which are welded to the same on the occasion of the formation of the longitudinal edges.
The drawing shows an example of an embodiment of a garbage bag with a closure member according to the invention. The bag shown consists of a plastic film, e.g. made of transparent polyethylene, which is folded along the bottom edge 1 and welded along its longitudinal edges 2, 3. Below the bag opening 4 are two bands 5, 6, also suitably made of polyethylene, arranged transversely to the longitudinal direction of the bag, which are welded at the longitudinal edges 2, 3 to the film forming the bag. To close the filled bag, the straps 5, 6 are cut in the vicinity of one weld seam, while they are still connected to the other weld seam. The free ends of the two straps can then be looped around the gathered bag opening and linked together.
The production of the described bag, including the closure member attached to it, takes place in one operation. Here, a device for receiving two e.g. about 4 cm wide rolls created.
An endless belt each runs from below and from above onto the bag's hose path running through the bag machine.
Together with the latter, the tapes are fed into the welding station. Here the hose web is separated by means of separating seam welding. This creates the individual bags and the two belts 5, 6 are welded on at the same time and separated from the endless belt.
PATENT CLAIMS
I. Waste bag made of plastic, with a closure member attached to it for closing the bag opening, characterized in that the closure member is formed by strips of weldable material which are arranged below the filling opening and which are welded to the same at the longitudinal edges of the bag.
II. A method for producing the garbage bag according to claim I, in which the longitudinal edges of the same are formed by welding a plastic film, characterized in that below and above the tubular path of the bag, transversely to the same running bands of weldable material, which on the occasion of the formation of the longitudinal edges be welded to the same.
