Thecurrent invention pertains to certain novel
features of advantageousstructure and resulting
bene?cial properties in the bases or bottoms of
receptacles or containers, such, for instance, as
those used for accommodating toilet preparations,
as for example, face-powder.
It is not new to make boxes holding powder
containing drums with frangible or rupturable

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.
Such ?lled containers are subjected to various.
