Abstract

L'invention porte sur un tissu de filtre préliminaire qui est particulièrement conçu et adapté de façon à être utilisé avec le ShopVac®, le Craftsman™, le Rigid® ou tout autre type similaire d'aspirateur eaux ou poussières. Le tissu de filtre préliminaire est formé sous la forme d'une enveloppe généralement rectangulaire, constituée d'un feutre de tissu tissé et/ou non tissé polyester ayant un poids entre 6 et 16 onces. L'enveloppe rectangulaire forme deux côtés plans généralement parallèles, séparés par une construction plissée ou par tout autre type de construction à bord extensible, et comprend une extrémité ouverte qui est fermée de façon libérable, de préférence avec un agencement de fermeture à boucles et à crochets qui ferme hermétiquement l'extrémité ouverte pendant l'utilisation, mais qui permet l'ouverture afin de permettre la sortie du contenu recueilli. Un côté plan forme un portail d'entrée circonscrit par un rebord de liaison rigide pouvant permettre la fixation au raccord d'entrée de tuyau généralement disponible sur la paroi latérale intérieure de l'aspirateur-traîneau.
