Fitment And Overcap Therefor
Patent No. EP3265396 (titled "Fitment And Overcap Therefor") was filed by Aptargroup on Mar 5, 2015. The application was issued on May 6, 2020.
Patent Summary
A closure assembly for a container that enables enhanced cleaning and sterilization, particularly in hydrogen peroxide gas sterilization systems. The assembly comprises a fitment with a projecting spout and a mating overcap that together provide a configuration that facilitates cleaning and sterilization. The overcap has a long plug that engages with the fitment's interior sealing surface, creating a seal that is located low in the spout. This design minimizes the permeation of gases through the closure assembly, particularly oxygen, which can adversely affect products packaged in pouches. The assembly also features a frangible bridge that can be severed by a shear member during relative rotation between the cap and fitment, creating turbulence in the sterilizing gas flow to enhance sterilization.
