of the appended claims.
I claim:
1. A container closure having a continuous
down-turned peripheral ?ange, holes spaced
along said ?ange and inwardly of the edge there

of the general plane of said ?ange adjacent said
holes only.

2. A container closure having a continuous
down-turned ?ange adapted to be curled around
the false wire of a container, holes adjacent the
?ange edge forming lugs therebetween capable
of bending inwardly without interference with
each other, the edge of the ?ange being continu

ous across said holes, but bent out of the general
plane of the ?ange adjacent the holes.
3. A container closure comprising a body
portion and down-turned ?ange thereon, with
perforations spaced slightly from the ?ange edge,
the edge being deformed outwardly adjacent the
perforations only.
4. The closure de?ned by claim 3 character
ized by said perforations having an edge parallel
to the edge of said ?ange.

portion, a peripheral groove or channel, and per
10

closure being displaced from its initial position
adjacent said perforations to facilitate crimping
