CONTAINER WITH MOUTH AND CLOSURE WITH DISC SEAL

摘要

The container (10) has a container wall and an opening (11) for filling and removing particular fluent or pourable filling material (20) in an interior of the container. A closure (15) comprises a sealing disk (30) for closing the opening. The sealing disk is provided with a defined fluorescent pigment (32) in the closure such that the existence of the pigment is detectable with sensors (40). The defined pigment acts by a radiation element (41) e.g. laser pointer and infrared light radiator, and delivers radiation, which is detectable by the sensor.
