ABSTRACT:
A process for refurbishing used containers. The process includes cutting an end member from a sidewall of the used container. The sidewall is dedented to remove deformations therein. An indentation is then formed in the sidewall a preselected dimension from the cut end. The cut end is peripherally expanded to accommodate a new end member. The new end member may be formed from a conventional end member in which the seaming flange has been removed, and the end member inverted for receipt in the sidewall of the container. An axially extending leg portion of the new end member engages the indentation and a secure, sealing engagement is insured by welding the sidewall to the new end member along the indentation. Thereafter, a reinforcing chime may be applied to the terminal end of the sidewall.
