A composite lid of a cylindrical container includes an outer metal lid having an integral top wall and sidewall and an inner plastic lid having a top wall and sidewall fitted inside the outer metal lid such that a free end of the sidewall of the inner plastic lid extends beyond a free end of the sidewall of the outer metal lid. The composite lid can be fitted on a base having an integral bottom wall and sidewall such that the sidewall of the inner plastic lid frictionally engages the sidewall of the base. The outer metal lid can be formed by stamping sheet metal, the inner plastic lid can be formed by molding a polymer material and the base can be formed by molding a polymer material. The outer metal lid can be adhesively bonded or mechanically fitted to the inner plastic lid.

A container closure includes a generally planar body having a product side and a customer side. The container closure body defines a limited container opening and an actuation location. Further, the container body includes a force concentrating construction disposed adjacent the limited container opening.

A machine for manufacturing a closure that has: a workspace for receiving a blank, a rim punch arranged to engage a blank received within the workspace, a center punch arranged radially inside the rim punch, the center punch arranged to engage the blank received within the workspace to form a closure, and an ejection pin arranged to cause the center punch to move such that the closure disengages from the rim punch.

Equipment and related methods for manufacturing ring pull crowns are disclosed herein. In one embodiment, a method of manufacturing a ring pull crown may include forming a plurality of crown bodies from a first source material, and forming a plurality of pull ring and tab assemblies from a second source material. In addition, such a method may include forming a plurality of ring pull crowns by combining each crown body of the plurality of crown bodies with a corresponding pull ring and tab assembly from the plurality of pull ring and tab assemblies. Also, such method may also include forming a circumferential skirt that descends below a top of each ring pull crown, and removing the plurality of ring pull crowns from the first source material.

A method of forming a can end shell is provided which includes providing a can end shell having a central panel portion, a first panel radius around the central panel portion, a chamfer extending from the first panel radius, and a second panel radius around the chamfer, coining the can end shell to form a coined section in the first panel radius around at least a portion of the circumference of the central panel portion, and reforming the can end shell to form a step in the chamfer.

A can lid comprising: a main body comprising a laminate metal sheet, the laminate metal sheet comprising a metal sheet and a first resin film on a major surface of the metal sheet, the major surface having a score line delimiting an opening piece, the first resin film comprising a first resin layer comprising a dimer acid-copolymerized polyester resin and being amorphous; and a tab attached to the main body and adapted to cause a cleavage along the score line.

A retainer assembly includes a retaining member assembly and a motion assembly. The retaining member assembly is structured to selectively retain at least one shell in a transfer belt assembly belt recess. The retaining member assembly includes a retaining member. The motion assembly is structured to move the retaining member between a first position, wherein the retaining member is spaced from the transfer belt assembly transfer belt, and, a second position, wherein the retaining member is disposed a retaining distance from the transfer belt assembly transfer belt.

A method of manufacturing a can lid composed of a composite material comprising at least one sheet metal part, in particular an aluminum part or a tin plate part, and at least one plastic part, in particular composed of polypropylene or polyethylene terephthalate, wherein the plastic material and the sheet metal part are joined together by pressing together and by inductive heating to effect a stable connection with an effort and a manufacturing time that are as small as possible.
