Metal packaging with tubular part

Abstract

The metal packaging includes a tubular part ( 1 ) defining a longitudinal axis ( 1′ ), which tubular part ( 1 ) includes a one-piece annular structure ( 10 ) made up of one moulding ( 11 ) or of several mouldings ( 11 ) which are formed on a plane ( 13 ) running perpendicular to the longitudinal axis ( 1′ ) and on the circumference of the tubular part ( 1 ) to form an annular lower surface ( 12 ) against which a handling member is intended to rest.

1 . A metal package including a tubular part ( 1 ) defining a longitudinal axis ( 1 ′), characterized in that said tubular part ( 1 ) includes an integral annular structure ( 10 ) consisted of one bead ( 11 ) or several beads ( 11 ) that are formed in a plane ( 13 ) extending perpendicular to said longitudinal axis ( 1 ′) and at the circumference of said tubular part ( 1 ), to form a lower annular surface ( 12 ) against which a handling member is intended to rest. 
     
     
         2 . The metal package according to  claim 1 , characterized in that the integral annular structure ( 10 ) includes one or several beads ( 11 ) formed in protrusion towards the inside and/or towards the outside of the tubular part ( 1 ). 
     
     
         3 . The metal package according to  claim 1 , characterized in that the integral annular structure ( 10 ) includes a continuous annular bead ( 11 ) extending over the whole circumference of the tubular part ( 1 ). 
     
     
         4 . The metal package according to  claim 3 , characterized in that the continuous annular bead ( 11 ) has the shape of an open rib, opening towards the inside or towards the outside of the tubular part ( 1 ). 
     
     
         5 . The metal package according to  claim 3 , characterized in that the continuous annular bead ( 11 ) has the shape of a closed rib, constituting an integral collar, protruding outwardly, which is formed of two planar annular flanges ( 16 ) in rest against each other and connected by a peripheral folding line ( 17 ). 
     
     
         6 . The metal package according to  claim 1 , characterized in that the integral annular structure ( 10 ) includes at least one variation of curvature ( 20 ) in the plane ( 13 ) passing through said annular structure ( 10 ). 
     
     
         7 . The metal package according to  claim 6 , characterized in that the integral annular structure ( 10 ) comprises at least one bead ( 11 ) extending over only a portion of the circumference of the tubular part ( 1 ). 
     
     
         8 . The metal package according to  claim 7 , characterized in that the integral annular structure ( 10 ) includes several beads ( 11 ) that are distributed over the circumference of the tubular part ( 1 ). 
     
     
         9 . The metal package according to  claim 6 , characterized in that the integral annular structure ( 10 ) includes one or several notches ( 20 ). 
     
     
         10 . The metal package according to  claim 9 , characterized in that the bottom ( 20   a ) of the notch ( 20 ) or of at least one of the notches ( 20 ) extends in the circumference, or at least approximately in the circumference, of the tubular part ( 1 ). 
     
     
         11 . The metal package according to  claim 1 , characterized in that it consists in a container including a neck ( 1 ) forming said tubular part, and in that said neck ( 1 ) is ended by a mouth ( 2 ) provided with an upper portion ( 2   a ) for receiving a plug and a lower portion ( 2   b ) including the integral annular structure ( 10 ). 
     
     
         12 . A method for manufacturing a metal package according to  claim 1 , characterized in that it consists in:
 (a) manufacturing the tubular part ( 1 ) of the package, and   (b) locally deforming said tubular part ( 1 ) to form the integral annular structure ( 10 ) consisted of one or several beads ( 11 ).   
     
     
         13 . The metal package according to  claim 2 , characterized in that the integral annular structure ( 10 ) includes a continuous annular bead ( 11 ) extending over the whole circumference of the tubular part ( 1 ). 
     
     
         14 . The metal package according to  claim 2 , characterized in that the integral annular structure ( 10 ) includes at least one variation of curvature ( 20 ) in the plane ( 13 ) passing through said annular structure ( 10 ). 
     
     
         15 . The metal package according to  claim 7 , characterized in that the integral annular structure ( 10 ) includes one or several notches ( 20 ). 
     
     
         16 . The metal package according to  claim 8 , characterized in that the integral annular structure ( 10 ) includes one or several notches ( 20 ).
