Folded packing with recessed grip, for powders - has hose-like inner case with folded grooves, and without slot-like openings

摘要

The packing (36) is formed from a folded blank with four walls, and connected cover- and base tabs. One wall (4) has a grip opening (38), formed by folding a grip tab (15) along a fold line (19). The side walls of the packing have an internal hose-like case, to form double walls. The side wall (23) of the inner case engaging on the grip tab has a cross line, extending through it parallel to its upper and lower edges. The line is formed under the lower grip opening edge (38). Two V-shaped lines (32, 33) extend from the ends of the cross line towards the upper edge of the inner case. ADVANTAGE - Improved impermeability to powders.
