Gusseted bag made of a thermoplastic foil and provided with ventilating openings
Abstract
Ein Sack aus thermoplastischer Kunststoff-Folie besteht aus einem mit eingelegten Seitenfalten versehenen Schlauchabschnitt, der im Bereich seines durch eine querverlaufende Bodenschweißnaht gebildeten Bodens und/ oder im Bereich seiner später durch eine querverlaufende Kopfschweißnaht zu verschließende Öffnungsseite mit sogenannte Eckabschweißungen bildenden, durch die beiden jeweils äußeren Lagen der Seitenfaltung ausgeführten Schweißnähten versehen ist, die schräg von den äußeren Kanten der Seitenfalten nach innen und in Richtung auf die Boden- und/oder späteren Kopfschweißnähte verlaufen und im Bereich der Innenfaltkanten enden. Der Sack ist mit Öffnungen zur Entlüftung des gefüllten Sackes versehen. Damit die Entlüftungsöffnungen besser gegen äußere Einflüsse und insbesondere gegen das Eindringen von Wasser oder Feuchtigkeit geschützt sind, sind die die Eckabschweißungen (7, 7') bildenden Schweißnähte (5) mit Entlüftunskanälen bildenden Unterbrechungen (6) ausgeführt. Mindestens je eine Wandung der durch die Eckabschweißungen gebildeten Zwickel (7, 7') weist Perforationen auf (Figur 1).
