Vial closure assembly for sealing containers
The patent US12071279B2 describes a vial closure assembly designed to enhance the sealing and usability of containers, particularly in pharmaceutical applications. The assembly consists of several components: a ring with a top wall and a skirt featuring locking tabs, a cover with an interior cavity and aligned through-openings, a cap with engaging tabs, and a shell with inwardly extending lips and rails. The design allows for independent rotation of the shell relative to the cover, which may facilitate easier access and manipulation. The assembly can be constructed from pharmaceutical-grade plastic, ensuring safety and compliance for medical use. Additionally, the inclusion of an elastomeric stopper within the ring's skirt provides a secure seal against the container's opening.
Further claims detail the structural features of the assembly, such as the tapered and arcuate design of the rails on the shell, which are intended to enhance contact with the cover or ring. The skirt of the ring may also incorporate a flexible tongue for improved engagement. The patent outlines two variations of the vial closure assembly, both of which include a sealed container assembly that integrates the closure with a container featuring a neck and rim. This comprehensive design aims to provide a reliable and efficient closure solution for vials, addressing the needs of the pharmaceutical industry for secure and user-friendly packaging.
