Abstract: A flexible duct able to be removably inserted to partially nest into a rigid tube that has an annular channel. The flexible duct comprises of a cylindrical flexible plastic film to convey flowable matter. An injection moulded cuff is provided at an end of the cylindrical plastic film that is over-moulded to the flexible film and that is over-moulded to a resilient band that is held captive by the flexible plastic film and/or the injection moulded cuff. The cuff has an annular rib that can nests in the annular channel. The cuff and resilient band are able to inwardly collapsible to facilitate insertion to and removal of the rib from the rigid tube.

Abstract: A bag loading nozzle to confine a flow of material from upstream feed for downstream discharge into a bag having a spouted entrance. The nozzle comprising an interior wall presenting an inlet and an outlet, located intermediate of the inlet and the outlet and about the interior wall is a shape retaining tube through which the material is to pass from the feed into the bag. At least one actuable fluid inflatable collar at least substantially about the shape retaining tube is provided such that when actuated to its inflated form it will effect at least a substantial sealing with a fitted suitable bag from within its spouted entrance.

Abstract: A cuffed connection system for the transport of a particulate material includes a tube, a conduit, or a duct, and a flexible tube end received and snap fit inter-engaged within the tube, the conduit, or the duct. The snap fit is of a pair of outward circumferential forms each into a complementary receiving groove of a ferrule.
