ARaymondlife has designed RayDyLyo, its patented closure device for sterile vials. 

Developed within ARaymondlife's engineering office, RayDyLyo is an optimized plastic closure system presented as an alternative to the aluminum cap. 

Responding to regulatory developments especially in aseptic filling (GMP appendix 1), RayDyLyo eliminates crimping for liquid and lyophilized formulations. It is offered in three diameters, 13, 20 and 32 mm, to suit varioius applications. 

Two versions exist: CTO (central tear-off) for injectable products and TTO (total tear-off), in development, for product reconstitution and mixing.
