Abstract:
1. A process for construction of a multi-layer cylindrical container comprising the steps of: (a) cutting separately a first sheet and a second sheet in rectangular shapes and with one corner of each sheet having a recess, the first sheet forming an interior sheet, the first sheet being slightly greater in height than the second sheet and being slightly greater in height in the recess, and the first sheet being made of a metallic material; the second sheet comprising at least two layers, including an external layer of plastic material and an inner layer of plastic material, the external layer having a plurality of cylindrical areas forming lenses, the lenses, depending on viewing angle, reflecting different images incorporated on the inner layer of plastic material; (b) superimposing the first and second sheets without adhesives and securing the first and second sheets to each other; (c) uniting end sides of the first and second sheets by hooking the end sides together to form a tube from the first and second sheets so that one corner of the first and second sheets is in an upper vertical position; (d) rounding off a rim of the first sheet to form a small flange at a top portion of the first sheet covering a rim of the second sheet so that one end of the flange overlaps another end of the flange in an area of the recesses of the first and second sheets, leaving an upper horizontal rim of the second sheet completely embedded in the flange of the first sheet except in a segment of the recess, wherein the upper horizontal rim of the second sheet is flush with a lower rim of the flange; (e) inserting a lower lip of the first sheet in a bottom piece of the container, the bottom piece being provided with a stepped portion; and (f) flanging the bottom piece to leave the bottom piece ready for introduction of a product and for insertion of a cover.
