A still further object of the invention is to provide a

be torn off to permit removal of the cap or cork from
a container but which is so constructed that suf?cient of
the cap or stopper will be left after the skirt is torn off,
to permit the cap or stopper to be used still as a non

surface 36 of the skirt portion 32 is preferably conical
and converges downwardly toward the inside surface 35

The stopper or cap has a hollow shank portion 54, a

of the portion of skirt 34 above rib 38 is much larger
than the inside diameter of collar portion 31, in fact, ap

Hence, skirt 34 above rib 38 is of relatively thin section

formed on the bottle so that the internal rib 66 on the
skirt will be bent upwardly to engage tightly beneath the
rib 75 under tension thereby the more securely to hold the
cap or cork in the bottle. The rib 66 will lock the cap or
cork on the bottle and will cause the ?llet portion 63 to
seal tightly on the top of the bottle preventing loss of CO2
from the bottle. Due to the fact that the shank 54 is
made hollow, the pressure of the gas inside the shank will
press the ribs 57, 58 and 59 tightly against the inside wall
of the neck of the bottle thereby more securely holding
the cap or cork in the bottle.
