<p>The container is designed for a filler material which contains volatile constituents and/or constituents which must be protected against air entry, where the container body has its opening closed by a membrance which has a small weakness point. There are several projections along the container opening which cut through the closing membrane. The projections (5) are rigidly arranged either on the opening rim of the container body or on a holding ring (3) inserted into the container body (1). The opening rim at the container body or the holding ring (3) is saw-toothed or corrugated on the side facing the closing membrane (7). The closing membrane has a bracket (3) which grips over the opening rim externally.</p> |
