A number of such pouches demountably installed at successive loading stations along the sorter conveyor path are maintained suspended from parallel support arms in normally open, article receiving position with the front walls of the individual pouches bowed outwardly to accommodate the articles being discharged from the conveyor at such stations. With the pouches removed from the support arms, the front walls can be bowed inwardly against the sidewalls and rear wall in order to permit interengaging the cooperating elements of a closure device such as a slide fastener to secure the contents within the pouch for delivery purposes.
