The container includes a body including a tubular side wall with upper and lower edges that are double-seamed to end walls. The tubular side wall includes a deformation region formed by circumferential friezes, which are parallel and adjacent to each other and have a Z-shaped profile with their end legs disposed in planes which define, with the axis of the tubular side wall, an angle between 45° and 90°. The end legs are interconnected by a median leg inclined in relation to the axis and defining, with the respective end legs, an angle not superior to 90°. The adjacent end legs of two consecutive friezes being coplanar and interconnected, by their opposite ends, to the respective median legs.

1. An improvement in a container of metal sheet, comprising a body formed by a tubular side wall having an axis and having an upper end edge and a lower end edge to which are affixed, by an upper double-seam and a lower double-seam respectively, an upper wall and a lower wall, said tubular side wall
1. An improvement in a container of metal sheet, comprising a body formed by a tubular side wall having an axis and having an upper end edge and a lower end edge to which are affixed, by an upper double-seam and a lower double-seam respectively, an upper wall and a lower wall, said tubular side wall presenting, close to at least one of the upper double-seam and lower double-seam, at least one circumferential deformation region formed by a plurality of circumferential friezes parallel and adjacent to each other and occupying a certain axial extension of the tubular side wall, the improvement being characterized in that each frieze presents a Z-shaped profile having end legs disposed in planes which define, with the axis of the tubular side wall, an angle (α) between 45° and 90°, said end legs being interconnected by a median leg inclined in relation to said axis and defining, with respective end legs, an angle not superior to 90°, the end legs of two adjacent friezes being coplanar and interconnected, by opposite ends thereof, to respective median legs and characterized in that a junction of the median leg with the end leg, of each frieze, is obtained by a rounded vertex portion, coincident with the adjacent median leg and end leg and each rounded vertex portion presents a bend radius “r” having a value defined between ½ and ⅔ of a radial extension of the end legs of each frieze and further characterized in that the median legs of the friezes of an upper circumferential deformation region are downwardly and radially outwardly inclined from the upper double-seam, whilst the median legs of the friezes of a lower circumferential deformation region axe upwardly and radially outwardly inclined from the lower double-seam. 2. The improvement, as set forth in claim 1, characterized in that each upper circumferential deformation region and lower circumferential deformation region are connected to the adjacent upper double-seam and lower double-seam by an end leg of the outermost frieze, in the axial direction. 3. The improvement, as set forth in claim 1, in which the container has a tubular side wall with a square cross section, a metal sheet thickness of 0.34 mm and a volumetric capacity of 18 liters, the improvement being characterized in that each circumferential deformation region presents four friezes, each one having a height of 7.5 mm and a total width of 9 mm. 4. The improvement, as set forth in claim 1, characterized in that the median legs of the friezes intersect the certain axial extension of a contour of the tubular side wall. 5. The improvement, as set forth in claim 4, characterized in that the median legs of each frieze and the coplanar end legs of each consecutive two friezes are symmetrical in relation to the axial extension of the contour of the tubular side wall.
