摘要： The primary object of the present invention is to provide an easy-open lid having an opening score defining a portion to be opened, an opening tab formed on the portion to be opened and a covering strip of a protecting resin formed to stride over the opening score beyond both the sides of the score, which is excellent in the rusting-preventing property of the score portion and the stain resistance of the covering resin strip, and a process for the preparation of this easy-open lid.In the easy-open lid of the present invention, an organic resin coating is formed on the outer surface of the lid, the covering resin strip is formed of a plastisol of a vinyl chloride resin containing at least one additive selected from the group consisting of anchoring fillers, tackifiers and amino resins, and the covering resin strip is peelably bonded to the organic resin coating.

摘要： An apparatus for shaping a metallic pull ring and simultaneously connecting it to a container closure is disclosed. The apparatus includes a pre-shaped article former for shearing with a rotary shearing blade a rectangular metal blank from the end portion of a thin metal strip and simultaneously blending it to form an annular pre-shaped article having overlapped opposite ends, a closure feeder as well as a pre-shaped article feeder for continuously positioning a container closure and the pre-shaped article to a rotating support member in such a relation that the free end portion of a tear-off tab of the closure and a part of the pre-shaped article overlap each other and a pull ring shaper and connecter for curling the peripheral edge of the pre-shaped article in the radial direction to form it into a ring and simultaneously rolling the tear-off tab into said ring and connecting them to each other.
