Award of Patent No. EP 1666370 B1 Applicant: Closure Systems International Japan, Tokio (JP) Date of Application: 28.7.2004 Screw closure for a container. The closure is constructed so that, once a certain internal pressure is reached, it becomes elastically deformed and allows the pressure to escape to the outside. A bottle with a screw cap is secured by means of a sealing mark between the closure and the bottle. Unscrewing for the first time means that the seal will be irreversibly destroyed.
