Abstract
A reclosable can lid is described which does not require a separation of a metal surface associated with chip formation in the opening process, which ensures the respective required leak tightness on the reclosing, even in the case of a pressure build-up resulting in the respective container, and which has a high functional reliability with a particularly economical manufacturing option.
Claims15
A metallic can lid comprising:
- a reclosable opening;
- a microgap which extends peripherally, which is provided in a metallic lid surface and which is sealed off at an inner lid side by a film;
- a weakening line extending adjacent to said microgap in the film;
- a sealing frame composed of a plastic material which is connected to a fixed lid surface and which surrounds an opening region;
- a closure unit composed of a plastic material which is connected to a metallic lid region which is disposed within the microgap and which can be pivoted open, said closure unit being pivotably attached to the fixed lid surface and being provided with a tear-open member disposed diametrically opposite a pivot bearing region,
- wherein the sealing frame and the closure unit cooperate via sealing and latching ribs and associated receiving grooves and the metallic lid region disposed within the annular microgap is received and held in the opening region of the lid;
- wherein the film provided at the inner lid side and covering the microgap consists of a molded part, which reproduces a lower side structure of the can lid forming a continuous metallic surface;
- and
- wherein both the sealing frame is connected to the fixed lid surface in a bonded manner and the closure unit is connected to the metallic lid region that can be pivoted open in a bonded manner.
