Cylindrical Container Locking Adapter Pressure Interlock

The patent employs a composite structure combining a paperboard outer shell with an inner plastic liner and closure system. The paperboard provides structural integrity and recyclability, while the plastic components provide moisture barrier and sealing functions. This composite approach resolves the contradiction by integrating materials with complementary properties to achieve both strength and sustainability.

The pressure interlock mechanism uses simplified geometric shapes and pressure distribution patterns that replicate effective locking principles found in nature and existing systems. The interlocking tabs and slots use basic geometric forms that achieve child-resistant functionality without requiring complex mechanical components, thereby maintaining reliability while controlling complexity.

The container is segmented into distinct components including a permanent base portion and a destructively removable portion that can be separated. The removable portion includes features like perforated lines or weak points that allow easy separation for recycling purposes. This segmentation enables consumers to easily remove and recycle appropriate portions while simplifying the manufacturing process through modular component design.
