Latest Patents: Armstrong's latest patent, titled "Tamper-Indicating Closure with Resilient Locking Projections," showcases his ingenuity. This invention outlines a method for manufacturing a closure equipped with multiple resilient flexible projections, designed to be bent upwardly and radially inwardly at a predetermined radius of curvature. The process starts with creating a mold assembly that includes both a female mold portion for the closure's outer surface and a male mold portion for its inner surface and projections. The mold portions move toward and away from each other to create a mold cavity, where the closure is formed. After the material is injected into the mold and allowed to solidify, the male mold portion is removed, temporarily bending the projections. Each projection's design incorporates strain relief recesses, ensuring that the projection returns to its original shape following the molding process.
