Can with a Polygonal Cross Section

Abstract

The present can includes a tubular body (C) formed by lateral walls of rectangular contour and which are connected, two by two, by longitudinal edges, said tubular body (C) being closed by an upper wall and a lower wall. Each lateral wall incorporates a structural reinforcing means defined by a plurality of depressions having a polygonal or circular contour and located side by side, without overlapping and occupying at least one portion of the area of each lateral wall

1 . A can with a polygonal cross section, comprising a tubular body formed by lateral walls of rectangular contour and which are connected, two by two, by longitudinal edges, said tubular body being closed by an upper wall and a lower wall, the can being characterized in that each lateral wall incorporates a structural reinforcing means defined by a plurality of depressions, having a contour selected between the polygonal and circular shapes and located side by side, without overlapping and occupying at least one portion of the area of each lateral wall. 
     
     
         2 . The can, according to  claim 1 , characterized in that the contour area of each depression corresponds from 1/16 to ⅛ of the area of the lateral wall, and in that the depth of each depression is defined between 0.1 to 20 times the thickness of the metallic sheet. 
     
     
         3 . The can, according to  claim 1 , characterized in that the depth of the depressions, in each lateral wall of the tubular body, is progressively reduced in the vertical direction, from the lower depressions toward the upper depressions. 
     
     
         4 . The can, according to  claim 3 , characterized in that each depression has a bottom wall projecting toward the interior of the tubular body, the depth of the depressions in each lateral wall of the tubular body being progressively reduced according to a plane inclined in relation to said lateral wall and containing the bottom walls of the depressions. 
     
     
         5 . The can, according to  claim 4 , characterized in that the depressions are frusto-conical 
     
     
         6 . The can, according to  claim 5 , characterized in that the frusto-conical depressions are approximately tangent to each other. 
     
     
         7 . The can, according to  claim 4 , characterized in that the depressions are truncated pyramids having rectangular bases and rounded corners. 
     
     
         8 . The can, according to  claim 7 , characterized in that the depressions are spaced from each other by a distance corresponding from 1/40 to 1/20 of the width of the lateral wall.
