Container mouth resin geometry: SuntoryRecent Research Landscape

Dimensional instability at the container opening leads to seal failure and product leakage. Precision engineering of the preform mouth structure ensures airtight closure integrity during high-speed capping.

What technical problems is Suntory addressing in Container mouth resin geometry?

Inadequate mouth seal integrity

(11)evidences

Structural weaknesses or dimensional instability at the container opening lead to leakage and gas permeation. Ensuring a robust seal prevents product spoilage and maintains internal pressure.

Inadequate container mouth sealing

(3)evidences

Mechanical failure at the interface between the closure and the container mouth leads to leakage or contamination. Ensuring a robust physical barrier prevents product spoilage and loss of internal pressure.
