Latest Patents

One of Chartier's latest inventions is the Pilferproof cap, which is a tamper-indicating plastic cap designed for twist application to a threaded container neck. This cap comprises a body and a band interconnected by a series of bridges that slope upwardly in the direction of twist application. The design includes a plurality of drive devices with co-operating abutments on the cap and band, which are normally disengaged. As the band is snap-fitted over a bead on a threaded container shoulder, the bridges flex, allowing the abutments to engage and drive the band with the cap. This mechanism prevents the breaking of the bridges during application. The bridges are designed to break when the cap is unthreaded, facilitating the injection molding process by keeping the band spaced from the cap underside.

Another version of the Pilferproof cap is a plastic screw-on closure that indicates when a sealed container has been tampered with. This closure features a cap and a band for application over the shoulder of a container. The drive means ensures engagement between the cap and band during application, maintaining the integrity of the connecting means. However, during removal, the drive means becomes ineffective, causing the connecting means to fracture due to axial separation.
