Such open-bottom drums housed in their open
pasteboard disc inside "of the bott in‘;
bottom covers are ordinarily ?lled while they are
upside down with the powder to be marketed and,‘
then the bottom of the drum is snapped orforced
into place closing the bottom thereof and having
an extended marginal portion underlying the
lower edge of the removable cover when the box
is completed and is right side up.
