The closure assembly according to claim 1, wherein the gripping tab is substantially leveled with the upper ring and with the lower skirt, maintaining with said parts a gap along the whole extension thereof. 3. The closure assembly, according to claim 1, wherein the gripping tab is at least partially hollow, in order to define a handle. 4. The closure assembly, according to claim 3, wherein the gripping tab is axially and inferiorly extended beyond the lower skirt. 5. The closure assembly according to claim 1, wherein the gripping tab is solid. 6. The closure assembly according to claim 1, wherein the lower skirt is tightly seated around the circumferential extension of the upper end of the tubular body. 7. The closure assembly, according to claim 6, wherein the lower skirt incorporates the ends of a seal bridge, circumferentially extended over the interruption of the seal portion and over the gripping tab, a first end of said ends of the seal bridge being incorporated to the lower skirt by connecting means to be ruptured when said first end is forced away from the lower skirt, in order to liberate the manual access to the gripping tab. 8. The closure assembly, according to claim 7, wherein the seal bridge has its first end disposed over the lower skirt and incorporated to the lower skirt by two connecting means that are circumferentially spaced from each other. 9. The closure assembly according to claim 6, wherein the seal portion comprises at least one breakable lock connecting the gripping tab to at least one of the parts defined by the upper ring and by the lower skirt of the seal portion. 10. The closure assembly according to claim 1, wherein the upper ring incorporates an upper circumferential rib projecting over the upper end of the tubular body, in order to fit loosely and telescopically in the lower end of another tubular body stacked over the first one. 11. The closure assembly according to claim 10, wherein the upper circumferential rib is continuous. 12. The closure assembly according to claim 10, wherein the upper circumferential rib fits around the lower end of said other tubular body stacked over the first one. 13. The closure assembly according to claim 10, wherein the upper circumferential rib fits in the interior of a circumferential recess provided internal to the lower end of said other tubular body stacked over the first one. 14. A closure assembly comprising: a lid; and a can comprising a tubular body having a lower end and an upper end carrying a seat for the hermetic seating of the lid, the lid comprising: a sealing portion, which is removably seated and retained in the seat and provided with an upper edge projecting radially outwardly from the seat; and a seal portion having a lower skirt seated around part of the upper end of the tubular body, and an upper ring seated on part of the upper end of the tubular body and being incorporated, externally, to the lower skirt and, internally and through radial bridges, to the upper edge of the sealing portion, the seal portion presenting, in its circumferential extension, an interruption extending through a width of the upper ring and through at least part of a height of the lower skirt, wherein the sealing portion incorporates a solid gripping tab projecting radially outwardly and axially downwardly through said interruption of the seal portion, the gripping tab being manually operable only when part of the seal portion is ruptured, said radial bridges being ruptured when submitted to a certain pulling force to separate the seal portion from the sealing portion, when the lid is opened for the first time, and wherein the seal portion incorporates a first and a second axial cut, each extending through at least the height of the lower skirt and defining a rupture portion of the lower skirt that is superiorly incorporated to the upper ring, and wherein each of the first and the second axial cuts define a spacing between respective confronting edges of the rupture portion of the lower skirt and a remaining portion of the lower skirt, and wherein the gripping tab is defined in a the rupture portion of the lower skirt , and wherein the rupture portion of the lower skirt is adapted to be ruptured after the sealing portion is separated from the seal portion when the lid is opened for the first time, such that the seal portion is completely removable from the tubular body. 15. The closure assembly according to claim 14, wherein the rupture portion of the lower skirt is defined by a “U” shaped strip maintaining a gap around a respective extension of the gripping tab, separating it from the rupture portion. 16.
