A ribbon of packaging comprises individual packages (11) adjacently and separably arranged for separation prior to filling. The ribbon is preferably drawn under tension from a reel, and the packages are linked by mechanical couplers (FIG. 11) which are separable in a direction orthogonally to the traction force. The packages have a closure (FIG. 8) which is removed and replaced to permit filling. Also disclosed are preferred package couplers, and filling and dispensing arrangements.
