Misalignment between internal storage components and external dispensing interfaces leads to leakage or mechanical failure. Precise indexing ensures consistent product delivery and structural integrity during use.

Plastic aerosol and refillable cosmetic containers face structural deformation or bursting under high internal propellant pressure. Ensuring integrity prevents product leakage and container rupture.

Multi-part cosmetic packaging often suffers from structural instability or leakage due to improper fit between separate components. Consolidating into a one-piece compressible design eliminates interface failures and reduces manufacturing complexity.

Incompatibility between rigid thermoplastic components and flexible cardboard substrates leads to structural failure and leakage. Preventing separation ensures container integrity and product preservation.
