Claim 7

An assembly of two containers in which an auxiliary container is connected to a main container and its closure member, comprising a main container having an open end bordered by an outer wall and havig an internal ring at said open end with its internal periphery spaced from the wall of said container by an internal peripheral abutment on said wall, a closure member having an axially projecting annular protrusion frictionally fitting in said ring to close the open end of said main container, said closure member having a rim projecting radially outwardly from said protrusion and overlying said peripheral abutment, an auxiliary container having an open end bordered by a peripheral wall formation, said wall formation surrounding and closely fitting said rim on said closure member and having a peripherally extending bead formation projecting radially inwardly from the peripery of said wall formation at said open end and underlying said rim, said auxiliary container having a radial platform axially spaced from said bead formation and extending inwardly from said wall formation to form a channel receiving the rim of said closure member to connect said auxiliary container to said closure member, said wall formation and said bead formation having discontinuities at a plurality of points about the periphery to form a sectional wall formation and bead formation, said wall formation at the open end of said auxiliary container closely fitting in the wall at the open end of said main container and confined between said rim and said wall at the open end of said main container, said bead formation being confined between said rim and said abutment to connect said auxiliary container to said closure member and said main container, so that said auxiliary container cannot be separated from said main container when said closure member engages and closes said main container.

Claim 8
