Ribbed Container Neck Structure for Hot-Fill Seal Integrity

The patent applies local quality by adding a rib structure specifically at the neck region of the container where cap engagement occurs. This localized structural enhancement provides additional rigidity and resistance to distortion at the critical neck area without modifying the entire container, thereby maintaining seal integrity while preventing neck deformation during cap engagement.

The patent segments the neck structure by introducing a distinct rib feature that divides the neck wall into separate regions. This segmentation creates a reinforcing element that strengthens the neck against distortion while maintaining a relatively simple overall container design. The rib acts as a discrete structural component that can be integrated into the blow-molding process without significantly complicating the manufacturing system.

The patent applies preliminary action by incorporating the rib reinforcement into the neck structure during the initial blow-molding manufacturing process. This pre-integrated reinforcement ensures that the neck is structurally prepared to withstand the thermal and mechanical stresses of hot-fill and pasteurization processes. By establishing the strengthened neck configuration during manufacturing, the design maintains precision requirements while ensuring temperature resistance capability.
