Container with a security closure

Abstract

The container comprises a container body ( 1 ) and a sealing cap ( 9 ) which may be screwed to the container body ( 1 ). Barbs ( 5 ) are circularly distributed on the container body ( 1 ). Said barbs ( 5 ) each comprise a run-up ramp ( 7 ) and a locking surface ( 8 ). The sealing cap ( 9 ) is connected to a security ring ( 16 ) by means of break-off webs ( 15 ). The security ring ( 16 ) comprises projections ( 17 ) extending inwards from the inner circumference thereof, with run-up ramps ( 18 ) and locking surfaces ( 19 ). On closing the sealing cap ( 9 ) the run-up ramps ( 7;18 ) slide over each other. On unscrewing the sealing cap ( 9 ) an opposing blocking occurs due to the locking surfaces ( 8;19 ). The security ring ( 16 ) is thus blocked relative to the sealing cap ( 9 ), whereupon the break-off webs ( 15 ) are torn off.
