Can for bulk products

Abstract

A can for bulk products, comprising: a tubular body ( 10 ) in metallic sheet, having at least one peripheral lateral wall ( 11 ), and one annular upper wall ( 12 ) presenting an external edge ( 12 a ) affixed to the peripheral lateral wall ( 11 ), an internal face ( 12 b ) turned to the interior of the tubular body (10) and an internal edge ( 12 c ) defining an opening ( 13 ); and a lid ( 20 ) to be removably fitted and retained in the opening ( 13 ) of the can, in order to close it. According to the invention, the annular upper wall ( 12 ) has any point of its internal face ( 12 b ) disposed at a height, measured in the interior of the tubular body ( 10 ), at minimum equal to the height of another point of said internal face ( 12 b ) which is disposed in a radially external manner, aligned and adjacent in relation to said point.

1 . A can for bulk products, comprising: a tubular body in metallic sheet, having at least one peripheral lateral wall and one annular upper wall presenting an external edge affixed to the peripheral lateral wall, an internal face turned to the interior of the tubular body and an internal edge defining an opening; said can presenting the external edge of its annular upper wall double seamed to an upper edge of the peripheral lateral wall of the tubular body and a lid to be removably fitted and retained in the opening of the can, in order to close it, wherein the annular upper wall has any point of its internal face disposed at a height, measured in the interior of the tubular body, at minimum equal to the height of another point of said internal face disposed in a radially external manner, aligned and adjacent in relation to said point.  
   
   
       2 . The can as set forth in  claim 1 , wherein the points of the internal face of the annular upper wall, disposed according to the same circumferential alignment concentric to the axis of the tubular body, are contained in a plane orthogonal to said axis.  
   
   
       3 . The can as set forth in  claim 2 , wherein along at least one portion of the radial extension of the annular upper wall, the internal face of the latter presents a height which progressively and continuously increases toward the opening.  
   
   
       4 . The can as set forth in  claim 3 , wherein the internal face of the annular upper wall presents the external radial extension portion, adjacent to the peripheral lateral wall of the tubular body, disposed in a plane orthogonal to the axis of the tubular body.  
   
   
       5 . The can as set forth in  claim 3 , wherein the internal face of the annular upper wall presents an internal radial extension portion adjacent to the opening disposed in a plane orthogonal to the axis of the tubular body.  
   
   
       6 . The can as set forth in  claim 1 , wherein the internal edge of the annular upper wall is upwardly and radially outwardly bent, in order to form a circumferential rib with the cross section defined by at least one portion of an arc of a circle with the center in a plane orthogonal to the axis of the tubular body and medianly sectioned by said plane, said lid having a peripheral lateral wall externally provided with a circumferential cradle presenting a cross section in the form of an arc of a circle and within which is fitted the portion in the form of an arc of a circle the circumferential rib, said peripheral lateral wall of the lid having an upper section incorporating an external peripheral flange which is seated on the circumferential rib upon fitting the latter in the circumferential cradle of the lids, which is maintained in the closing condition of the opening.  
   
   
       7 . The can as set forth in  claim 6 , wherein the external peripheral flange is continuous and seated on an adjacent portion of the annular upper wall of the can, when the lid is closed.  
   
   
       8 . The can as set forth in  claim 6 , wherein the external peripheral flange incorporates small radial extensions angularly spaced from each other and which are configured to seat on the annular upper wall of the can, when the lid is closed.  
   
   
       9 . The can as set forth in  claim 8 , wherein the external peripheral flange incorporates two diametrically opposite radial bridges connecting and articulating, to said external peripheral flange, the ends of a pair of opposite semicircular gripping handles, slightly and radially spaced from the peripheral flange and which are medianly incorporated, through breakable radial connections, to the small radial extensions of the external peripheral flange, said gripping handles being medianly and angularly displaced from an inoperative position, substantially coplanar to the small radial extensions and incorporated thereto until the first opening of the lid, and a raised operative position after the rupture of the breakable radial connections.  
   
   
       10 . The can as set forth in  claim 1 , wherein the lid comprises a basic annular wall, from whose external edge is upwardly projected the peripheral lateral wall, which is internally incorporated to an upwardly displaced central tubular drawn portions.  
   
   
       11 . The can as set forth in  claim 1 , wherein the lid is made of any one of the materials defined by plastic, metal, and compositions thereof.  
   
   
       12 . The can as set forth in  claim 2 , wherein said can presenting the external edge of its annular upper wall double seamed to an upper edge of the peripheral lateral wall of the tubular body, wherein the annular lower wall has its height limited by a plane containing the upper edge of the peripheral lateral wall of the tubular body.  
   
   
       13 . The can as set forth in  claim 6 , characterized in that the peripheral lateral wall of the lid has an upper section incorporating an external peripheral flange which is seated on the circumferential rib upon fitting the latter in the circumferential cradle of the lid, which is maintained in the closing condition of the opening.
