The packing is used in the food industry for containing soft drinks, detergents and industrial lubricants. It consists of a bag of band -type foil having an opening bottom of the same material, fused along its seams on all sides, and of an inserted neck with airtight cap and handle, all sides being fused thus forming an airtight packing which can be filled during the fusing of its individual parts. The packing can be carried freely and be conveniently held during usage and its content can be partially emptied after which it is closed again and the remainder of the content is protected from spilling or soiling. The empty packing occupies very little space which is an advantage when it is transported away as a waste product. (11) 165
