Abstract
Embodiments of methods and apparatuses for providing a container with a lining are provided. A lining element is displaced into the interior of the container and coupled to the interior surfaces of the container to substantially cover the interior of the container.
Claims27
A method of providing a container comprising:
- providing a metal cylindrical sidewall and a metal can end double-seamed to the sidewall, the sidewall having an interior surface and an exterior surface and extending from a first open end to a second end closed by the can end, the can end having an interior surface, the sidewall and the can end defining an interior of the container;
- providing a liner sheet proximate the first end of the sidewall, the liner sheet having a first surface and a second surface opposite the first surface;
- displacing the liner sheet toward the can end into the interior of the container;
- displacing air from between the can end and the liner sheet;
- and
- displacing air from between the sidewall and the liner sheet outside of the container and applying the first surface of the liner sheet to the interior surface of the sidewall.

A method of providing a container comprising:
- providing a metal container including a sidewall having an interior surface, the sidewall extending from a first open end to a second end and an can end having an interior surface, the can end coupled to the sidewall closing the second end of the sidewall, the sidewall and the can end forming an open-topped enclosure;
- providing a BPA-free film;
- and
- adhering the BPA-free film to interior surfaces of the sidewall and the can end such that the film is substantially continuously applied to the interior surfaces of enclosure, the sidewall, and the can end.

An apparatus for applying a lining into a metal container, the metal container including a sidewall double-seamed to a can end, the container having a first open end and a second closed end, the apparatus comprising:
- a film mechanism configured to provide a film having a first side and a second side opposite the first side;
- and
- a film displacement mechanism on the opposite side of the film as the metal container, the film displacement mechanism displaceable from a location outside the metal container through the first open end to a location inside the metal container proximate the can end thereby displacing the film into the container, the displacement mechanism being further displaceable from the location proximate the can end to a location outside of the container and configured to displace air from between the film and the sidewall such that the film is coupled to the sidewall.
A method of providing a can comprising:
- providing a metal cylindrical sidewall and a metal can end double-seamed to the sidewall, the sidewall having an interior surface and an exterior surface and extending from a first open end to a second end closed by the can end, the can end having an interior surface, the sidewall and the can end defining an interior of the container;
- providing a liner sheet, the liner sheet having a first surface and a second surface opposite the first surface, a first thickness, a center portion, and a radial periphery;
- heating the container;
- heating the liner sheet;
- providing a displacement mechanism including a liner sheet displacement portion with a bottom portion and a sidewall;
- creating a vacuum proximate the liner sheet displacement portion configured to displace the radial periphery of the liner sheet toward the sidewall of the displacement mechanism;
- displacing the liner sheet displacement portion and the liner sheet into the interior of the container;
- and
- expelling fluid from the liner sheet displacement portion displacing the liner sheet away from the sidewall of the liner sheet displacement portion toward the metal cylindrical sidewall.
