ABSTRACT:
The invention comprises a returnable, non-corrosive metal container that can be cleaned and sterilized for re-filling with a pressurized beverage, the container having a tapering side wall with an integral bottom wall end and an open top end having a beaded rim to receive and sealably hold a removable closure, and ledge means extending from the side wall in predetermined spaced relation with one of the top and bottom ends for nestably receiving another similar container with the tapering side wall thereof being spaced away from the first container side wall in a non-locking relationship. The invention also comprises the process of manufacturing returnable, tapered and nestable non-corrosive metal containers including forming a basic container configuration from sheet metal by blanking in scroll pattern and making a first draw, making a second draw, making a third draw and tapering the side wall of the container while starting a rim curl, optionally making a further draw and taper or reshape while maintaining the rim curl, trimming the top rim and shaping the start curl, applying seal compound to the rim curl and forming a beaded rim, reshaping and cleaning excess compound, forming ledge means in the tapered container side wall, and final cleaning and stacking and packaging for shipment. The invention further comprises the process of handling tapered, non-corrosive metal containers for reuse including receiving stacked, used, empty containers in nested, non-locking relationship; inspecting pre-cleaned and de-labeled containers and reshaping and buffing damaged containers to a restored and reusable condition, palletizing columns of stacked, nested containers in multiple rows, sequentially transferring separate columns of containers and sequentially separating individual containers for refilling with a pressurized beverage product.
