Comar was the first blow molding company to market in North America with an ophthalmic child-resistant closure. Our SecureCap® closures utilize a patented two-piece push-and-turn technology that meet Consumer Product Safety Commission (CPSC) Protocol Title 16 of the Code of Federal Regulations (CFR) 1700.2.
Comar was the first to market with printed dosage cups for liquid medications.
Comar recently designed the DoseGuard®, which improved on bottle adapters that act as open flow restrictors. Our new valved bottle adapter offers closed flow control and a passive valve to help keep liquid medications child-safe for a new generation.
