1. A method comprising:
providing a neck for a metal body, the neck being formed of a metal sidewall;
forming an outward curl in the metal sidewall at a first end of the neck;
sliding a plastic outsert down onto the neck from the first end of the neck, the plastic outsert having a first inner diameter at a first end that is smaller than a diameter of the neck encompassing the outward curl, the outward curl flexing as the plastic outsert slides down onto the neck to accommodate the first end of the plastic outsert passing over the outward curl; and
retaining the plastic outsert on the neck between a first interference fit at a first interface of the metal sidewall and the plastic outsert and at a second interference fit between a top edge of the plastic outsert at the first end of the plastic outsert and the outward curl.
