Application March 5, 19,45,- Serial No. 581,086 '
. This inventionl relates to containers and par
ticularly to containers of that type having a body ,
of glass or similar vitreous material and ametal
sealing closure by which the container is closed
and sealed,.which closure is so constructed that
when the container is opened, the cover element
will remain hinged to the container so that it
can be repeatedly opened and closed again.
One of the objects of my present invention is
to provide a container of this general type in
which the metal closure member comprises a band

neck portion 2, and with an exterior downwardly
facing shoulder 3,V The outer surface 4 of the
neck 2 >between the top edge and the shoulder 3
is slightlyr'tapering, said surface being slightly
[smaller at the top edge than at the shoulder., ~
lThe metal ’sealing'closure for the container
f comprises a cap element 6, a band elementi-and
a sealingstrip, shown at 8 in Figs. 1 to'4.
