AI Technical Summary
Technical Problem
Existing packaging solutions for pourable products rely on visual indicators for tamper-proofing, which are not effective for visually impaired individuals or those in low-light environments, and do not ensure complete opening detection.
Method used
A tamper-evident opening device with a cap that rotates freely after initial opening, featuring a tamper-evident ring and a hinge mechanism to indicate complete separation from the spout, allowing tactile and visual verification of opening.
Benefits of technology
Provides a reliable tamper-proof mechanism that can be verified by touch or sight, ensuring complete opening detection and maintaining airtightness, suitable for visually impaired users and those in low-light conditions.
