<p>Packing boxes with a lower and an upper part (3 and 4) of cardboard material with an inner lining or facing, made from a single-piece cut-out (1), folded to form the box (2), ensure that the product packed is preserved as required for longer than if packed in known packing boxes, without other qualities of the packing box being thereby appreciably impaired. Such packing boxes should be even cheaper to produce than known packing boxes. This is possible either because the entire inner surface (6') of the lower part (3) is lined or faced, whilst the entire inner surface (7') of the upper part (4) is made entirely of cardboard material, or because the entire inner surface (6') of the lower part (3) is lined or faced with a first material whilst the entire inner surface (7') of the upper part (4) is lined or faced with a second material, the two lining or facing materials being physically different from one another.</p> |
