Latest Patents
E Joseph Stillwell holds a patent for a "Multi-walled tamper-proof container and method for enhancing tamper." This invention features a tamper-resistant vessel designed to contain liquids, utilizing a non-adherent multi-walled construction. In one embodiment, the container includes at least two adjacent non-adherent layers that create a void between them, allowing for tamper indication through discoloration that signals gross spoilage. The design incorporates an opaque inner wall and a closely spaced transparent outer wall, which, when punctured, allows the interior liquid to seep between the walls, mimicking spoilage. Another embodiment employs a multi-wall structure with transparent or semi-transparent walls, featuring a hydrophilic intermediate wall containing water-soluble dye particles. When punctured, the liquid activates the dye, creating a visual indication of spoilage. The materials used for the container's walls are flexible or fragible, complicating the concealment of tampering efforts.
