Latest Patents
Zipper's latest patents include innovations that enhance the design and usability of container closures. One of his notable patents is for a "Plastic closure and related container finish." This invention addresses the common issue of squaring in closure-neck finish arrangements. By constructing the neck finish to control the torque required for applying the closure, Zipper's design maximizes the pressures that typically lead to squaring. Additionally, the neck finish features a supporting surface that engages with the closure skirt, effectively preventing undesired squaring.
Another significant patent is for an "Expansion section for tamper-indicating ring of squeeze-off closure." This invention introduces a tamper-indicating band that prevents distortion of the closure during removal. The tamper-indicating ring consists of a continuous band that must be ruptured for removal. When heat is applied during processing, the band expands and then shrinks. Zipper's design resolves issues related to this expansion and shrinkage by forming the band in multiple sections connected by expansion segments.
