A metallic can end having a reclosable opening has a microgap or a weakening line peripherally around the opening, a sealing frame composed of plastic material surrounding the opening region, a closure unit composed of plastic that is disposed within the microgap or weakening line and that is pivotably attached to the fixed end surface via a pivot bearing. The sealing frame and the closure unit cooperate in a sealing manner. The metallic end region disposed within the peripheral microgap or the weakening line is received and held in the opening region of the end. The sealing frame is bonded to the fixed end surface and the closure unit is bonded to the upwardly pivotable metallic end region. Except for a possibly provided lacquer layer, the inner end side is at least largely free of lamination and the like.
A metallic can end having a reclosable opening, the metallic can end having an inner end side and an outer end side, the metallic can end having an upwardly pivotable metallic end region abutting a fixed end surface along a peripheral microgap or a weakening line provided in the metallic end surface and peripherally around an opening region, having a sealing frame composed of plastic material connected to the fixed end surface and surrounding the opening region, having a closure unit composed of plastic that is disposed within the microgap or the weakening line, that is connected to the upwardly pivotable metallic end region, and that is pivotably attached to the fixed end surface via a pivot bearing, wherein the sealing frame and the closure unit cooperate in a sealing manner, and the upwardly pivotable metallic end region disposed within the peripheral microgap or the weakening line is received and held in the opening region of the end, wherein the sealing frame is bonded to the fixed end surface and the closure unit is bonded to the upwardly pivotable metallic end region on the outer end side, and wherein, except for a possibly provided lacquer layer, the inner end side is at least largely free of lamination and the like.
The can end in accordance with claim 16, wherein the upwardly pivotable end region has a kind of droplet shape with a pointed region at the point of engagement of the tear-open member and a round region at the end remote therefrom at the pivot bearing.
The can end in accordance with claim 16, wherein the can end has an elongate hole in the region of the tear-open member which is adjoined at both sides by the microgap or by the weakening line;
A method of manufacturing a metallic can end having a reclosable opening, the metallic can end having an inner end side and an outer end side, the metallic can end having an upwardly pivotable metallic end region abutting a fixed end surface along a peripheral microgap or a weakening line provided in the metallic end surface and peripherally around an opening region, having a sealing frame composed of plastic material connected to the fixed end surface and surrounding the opening region, having a closure unit composed of plastic that is disposed within the microgap or weakening line, that is connected to the upwardly pivotable metallic end region, and that is pivotably attached to the fixed end surface via a pivot bearing, wherein the sealing frame and the closure unit cooperate in a sealing manner, and the upwardly pivotable metallic end region disposed within the peripheral microgap or the weakening line is received and held in the opening region of the end, wherein the sealing frame is bonded to the fixed end surface and the closure unit is bonded to the upwardly pivotable metallic end region on the outer end side, wherein a bonding agent is admixed to the respective plastic material to manufacture an injection molded plastic part.
