Amcor Rigid Plastics has launched a new child resistant (CR) closure, SerurePlus, for ophthalmic packaging. As a 15mm diameter polypropylene (PP) two piece closure, it uses a push and turn system which can be opened by adults. According to Amcor SecurePlus replaces today's single piece PP closures which are non child resistant. SecurePlus CR closures work on any 15mm diameter ophthalmic bottle. For example, it can be used for squeezable linear low density polyethylene (LLDPE) eye drop containers ranging from 5ml to 60ml.The product is developed in response to new federal government regulations that require child resistant closures for certain drug packaging, the company stated. A ruling from the US Consumer Product Safety Commission (CPSC) requires child resistant packaging for any over the counter or prescription product containing the equivalent of 0.08mg or more of imidazoline, a class of drugs that includes tetrahydrozoline, naphazoline, oxymetazoline, and xylometazoline in a single package.Products containing imidazolines can cause serious adverse reactions such as central nervous system (CNS) depression, decreased heart rate, and depressed ventilation in children who accidentally ingest them.
