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. V ‘ , It is not new to make boxes holding powder containing drums with frangible or rupturable (01. 1229-515) Figures 3 and 4 portray the'?rst'istep'i process of making the bottom;v_‘ r; Figures 5 and 6 depict theisecondqstep in ‘the ' method of forming the metal member of the bot tom; Figure 7 shows ' the pasteboarv disc; ‘ ‘a! Figure 8 presents the metal in tops which are broken through'when the powder pasteboard disc united together; Figure 9 reveals the applicat contents are to be used for the ?rst time. ' 10 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. V ' I, Figure 10 is a section through the joi'nplet' boxor container; and p p e j, I.
