Flange 35 preferably is formed to fit
down over the annular ring wall 24 when the parts
are in closed position. This flange terminates at
its lower outer end in the curl 2l. The curl 21
is preferably rolled inwardly and is adapted to
snap over the edge or rim 25 when the cover is
applied to the can thus securing the cover in
closed position.
The cover B may be hermetically sealed in
