A lid-seal for a metal container constituted by fixing, through a beading process, on the upper edge of a metal container (1) made of sheet metal, an assembly formed by a plastic membrane (2) and a stamped metal ring (3). The plastic membrane (2) has a peripheral portion (9), followed internally by a recess having therein a ring-like recess (10) and a perimetral ring-like reinforcement (11) and with a lower ring-shaped thin breaking line (12) which breaks when pulled, after the breaking of the short breaking portion (13) of the incorporated pulling ring (14). The stamped metal ring (3) has a flat inner section (4) with a central circular opening (5) with the inner edge beaded inwards (6) and an elevation to form an upper bed (7) and a peripheral edge turned downwards (8) so that, jointly with the peripheral portion (9) of the membrane (2) it can be beaded in the container (1). The disclosed lid-seal assures the necessary sealing and the consequent quality of the packaged product, and the certainty that there will not be any possibility of hurting the fingers upon opening.

1. A two-part lid-seal adapted for being fixed by beading on an upper edge of a container, comprising in combination a first part which is a unitary plastic membrane and a second part which is a metal ring;the plastic membrane having a peripheral flange portion and a central opening portion with a narrow breaking line therebetween, a pull ring being attached to the central opening portion for breaking the plastic membrane along the breaking line, to provide an opening giving access to the interior of such container; the metal ring having a central opening corresponding to said central opening portion in said plastic membrane and having an elevated outer section which forms an upper bed having a peripheral edge; said plastic membrane extending continuously over an entire underside and said central opening of said metal ring: the peripheral flange portion of the plastic membrane being shaped and located so as to nest in said upper bed of said metal ring, whereby said peripheral edge of said metal ring can be beaded on such container with the plastic flange portion forming a seal between said metal ring and such container. 2. The lid-seal of claim 1, in combination with a container, the peripheral edge of said metal ring being beaded on an upper edge of the container with said plastic flange portion forming a seal therebetween.3. The lid-seal of claim 1, wherein said breaking line is disposed inwardly from the central opening of the metal ring, whereby a user is protected from contacting the metal ring after the central opening portion of the plastic membrane has been opened.4. The lid-seal of claim 3, further comprising a reinforcement ring formed in the plastic membrane between the metal ring and the breaking line.5. The lid-seal of claim 4, wherein an inner edge of said metal ring, which defines said central opening, is bent outwardly, forming a beaded edge for said central opening.6. The lid-seal of claim 5, wherein said beaded edge of said central opening is received in a corresponding recess which opens upwardly in an upper surface of said plastic membrane.7. The lid-seal of claim 6, wherein said recess is defined in said plastic membrane at a location outward from said reinforcement ring.8. The lid-seal of claim 3, wherein an inner edge of said metal ring, which defines said central opening, is bent outwardly, forming a beaded edge for said central opening.9. The lid-seal of claim 8, wherein said beaded edge of said central opening is received in a corresponding recess which opens upwardly in an upper surface of said plastic membrane.10. A two-part lid-seal adapted for being fixed by beading on an upper edge of a container, comprising in combination a first part which is a unitary plastic membrane and a second part which is a metal ring;the plastic membrane having a peripheral flange portion and a central opening portion with a narrow breaking line therebetween, a pull ring being attached to the central opening portion for breaking the plastic membrane along the breaking line, to provide an opening giving access to the interior of such container; the metal ring having a central opening corresponding to said central opening portion in said plastic membrane and having an elevated outer section which forms an upper bed having a peripheral edge; whereby said peripheral edge of said metal ring can be beaded on such container; wherein an inner edge of said metal ring, which defines said central opening, is bent outwardly, forming a beaded edge for said central opening; and wherein said beaded edge of said central opening is received in a corresponding recess which opens upwardly in an upper surface of said plastic membrane. 11. A lid-seal of claim 10, in combination with a container, the peripheral edge of said metal ring being beaded on an upper edge of the container.
