Abstract: A sealing collar for a reconditioned container having a closure flange replaces an original sealing gasket which has been lost or destroyed in the reconditioning process. The collar comprises an end wall with (a) a radially inner portion matching a surface profile of a flange curl of the closure flange, and (b) a radially outer portion which diverges from the flange curl surface profile and extends radially outward beyond the outer diameter thereof. An annular outer side wall and the radially outer portion of the end wall together define an enlarged volume occupied by a sealing gasket. When the collar is crimped over the flange curl, the sealing gasket is compressed to seal between a flange pocket neck and the flange curl outside diameter.
