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.
Claims22
A process for reconditioning containers comprising the steps of:
- cutting an end member from a sidewall of a used container to define a terminal end;
- forming an indentation on said sidewall a preselected dimension from said terminal end;
- inserting a new end member having an extending leg portion for receipt in the sidewall and engagement with the indentation, said inserting step including positioning said leg portion for initial receipt in said sidewall;
- and,
- welding said sidewall along said indentation for sealing said new end member to said sidewall.
A process for refurbishing containers comprising the steps of:
- removing an end member from a sidewall of a used container to expose a terminal end;
- forming an indentation on said sidewall axially inward from said terminal end;
- inserting a new end member for receipt in the sidewall of the used container, said new end member having a portion extending axially from an end face, said leg portion received initially in said sidewall and disposed more closely adjacent said indentation than said end face;
- and,
- securing said new end member to the sidewall.
A process for refurbishing a used container of a first predetermined volume having a sidewall and an end member defined by an end face and an axially extending leg portion, said end face disposed axially inward from said leg portion, said end member being secured to the sidewall by a weld bead on the sidewall adjacent an interconnecting area of said end face and leg portion, said process comprising the steps of:
- cutting said end member from the sidewall of the used container at an area disposed axially inward from said weld bead to define a terminal end;
- forming an indentation on said sidewall axially inward a preselected dimension from said terminal end;
- inserting a new end membr having an extending leg portion for receipt in the sidewall adjacent the indentation, said inserting step including positioning said leg portion of said new end member for initial receipt in said sidewall;
- and,
- welding said sidewall to said new end member leg portion adjacent said indentation to form a refurbished container having a second predetermined volume substantially identical to said first preedetermined volume.
