| (54) | Improved closure for containers |
| (57) A closure (1) for a container has a rim (3) surrounding an opening to be closed.
The closure includes a lid portion (2) having a peripheral rim portion adapted to
sealingly engage the rim of the container (7), a peripheral ring portion extending
from the rim portion of the lid portion and having a depending portion (11) adapted
to engage the rim of the container to hold the peripheral rim portion in sealing engagement
with the container rim. The depending portion is formed with a multiplicity of separate
flexible finger elements (12) each having an inwardly directed abutment portion which
in use engages the rim of the container to hold the closure in the closed position,
said fingers occupying in their as moulded or neutral positions a position in which
the abutment portions are in use at least partially engaged with the rim of the container.
A locking ring (14) surrounds the peripheral ring portion and is movable over the
depending portion from a closed position in which the locking ring engages the depending
portion to hold it in engagement with the rim, to an open position in which the depending
portion is not constrained by the locking ring whereby the fingers can be flexed from
their neutral positions to be disengaged from the rim to allow the closure to be removed
by the application of a lifting force thereto.
