An apparatus and methods of sealing a metallic container with a metallic end closure are disclosed. The apparatus includes a tool operable to releasably join the closure to the container. In one embodiment, the tool is configured to form a thread in the closure and the container. The tool may optionally crimp the closure to the container. Once sealed, the container can be opened by rotating the closure in an opening direction. The closure can subsequently re-close the container by rotating the closure in a closing direction.

A method of manufacturing an evaporator includes: forming a length of tubing into a serpentine path, the length of tubing forming a tubing coil; forming a first evaporator plate; forming a second evaporator plate; positioning the tubing coil between the first evaporator plate and the second evaporator plate; bringing the first evaporator plate, the second evaporator plate, and the tubing coil into contact with each other; and forming a plurality of dimples in each of the first evaporator plate and the second evaporator plate, thereby at least partially crushing the tubing coil at a position of each of the plurality of dimples, a surface of each of the dimples contacting the tubing coil.

Ring pull crowns require equipment and related methods for manufacturing. A method of manufacturing a ring pull crown includes 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 metal closure for containers comprising a capsule designed to be applied to an opening of a container and including a circular part from which extends a perimeter edge. The perimeter of the edge has a rounding or folding obtained by curling and has a series of deformations made in a radial direction towards the centre of the capsule for forming the seal.

A reduced gauged crown for a container opening includes a corrugated panel portion such that the corrugation strengthens the crown material and allows less material to be used for the crown than would be used for an uncorrugated bottle cap.
