Closure assembly with breakaway sealing portion with gripping tab

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.

A lid comprising:

• a sealing portion, which is provided with an upper edge defined by an outer peripheral flange superiorly incorporated to the sealing portion;
• and
• a seal portion having a lower skirt and an upper ring being incorporated, externally, to the lower skirt and, internally and through radial bridges, to the upper edge of the sealing portion, the upper ring being provided in a plane which is substantially parallel to a plane defined by the upper edge, 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, the interruption defining a certain circumferential spacing between respective confronting edges of each of the upper ring and the lower skirt,
• wherein the sealing portion incorporates a gripping tab projecting radially outwardly and axially downwardly through said interruption of the seal portion, said 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 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, and
• wherein, for the purpose of forming a closure assembly comprising the lid and a tubular body, the lower skirt is adapted to be seated around part of an upper end of the tubular body, the upper ring is adapted to be seated onto a circumferential extension of the upper end of the tubular body, and the sealing portion is adapted to be removably seated in a seat defined by an annular upper wall that is internal to the tubular body.
