INTEGRAL PACKING BOX

摘要

A packing box (case/carton) constructed from sheet material, such as corrugated cardboard, comprises a base (10), side structure walls (12) and foldable flap members (1 and 2) with slits forming slots (3), tongues (4), or combined slot/tongues (3+4) and which incorporate creased bending lines (5), and/or slit bending lines (16 or 17), with creased and perforated bending lines (7) forming ledges (8), when folded with creased bending lines (13), and closure lide flaps (9). When flaps (1 and 2) are folded so that they are in contact with the article surface and engaged within the box, a thin walled structure is created within the void space between an article, less in height than the side structure wall height, and closure lid. This enables the article to be restrained from excessive movement or to enable the separation of articles during handling, transportation and storage.
