Cremation Urn Latch With Living Hinge

The latch mechanism is segmented into distinct functional elements: a catch feature on the lid, a protrusion on the base, and a living hinge connecting them. This segmentation allows each component to perform its specific function independently while contributing to the overall secure closure system.

The living hinge introduces dynamic functionality to the latch mechanism, allowing the lid to move between open and closed positions while maintaining secure engagement when closed. The hinge provides controlled movement and automatic engagement/disengagement capabilities without requiring complex mechanical assemblies.

The living hinge merges the hinge function with the latch mechanism by integrating the catch feature directly into the lid structure. This combination eliminates the need for separate hinge components and simplifies the overall mechanism while maintaining ease of operation.

The living hinge enables self-service operation where the lid automatically engages with the protrusion when closed and can be easily opened by applying force to the lid. The mechanism serves itself by using the natural movement of the lid to activate the latching and unlatching functions without requiring additional actuators or complex controls.

The design specifies a minimum distance parameter (three times the wall thickness) between the opening and rim, which provides a clear manufacturing guideline while ensuring adequate structural support. This parameter-based approach allows for variability within acceptable tolerances while maintaining the security requirement.

The use of injected molded plastic with integrated latch features allows for cost-effective manufacturing even with the positioning requirements. The molding process can accommodate the opening position specification while maintaining production efficiency and cost-effectiveness.
