Hinged Egg Container Closure with Ratchet Locking

The closure system is designed to automatically engage and lock when the cover portion is folded closed, without requiring consumer intervention. The ratchet mechanism and cam lever work automatically to secure the container, ensuring reliable closure even when consumers simply fold the cover shut without deliberate closing action.

The cam lever acts as an intermediary mechanism between the cover portion and the base. When the consumer folds the cover closed, the cam lever engages with the ratchet teeth to lock the closure, translating the simple folding motion into a secure locked state without requiring the consumer to directly manipulate locking mechanisms.

The closure system is divided into separate functional components: the ratchet mechanism for locking, the cam lever for engagement, and the hinge for movement. Each component performs a specific function and can be independently manufactured and assembled, simplifying the overall design while maintaining reliability.

The closure mechanism uses simple, inexpensive plastic components that can be easily molded and assembled. The ratchet teeth and cam lever are integrated into the molded plastic structure, eliminating the need for complex metal fasteners or multi-part assemblies, thus reducing both complexity and cost.

The friction surface means are integrated directly into the grasping wall structure during the molding process. The raised ribs or textured patterns are formed as part of the single-piece molded container, eliminating the need for separate components or post-manufacturing assembly steps.

The friction surface is created by modifying the surface geometry parameters of the grasping wall during molding. By changing the surface texture, rib height, or pattern density in the mold design, the friction characteristics are adjusted to optimize grip without requiring additional manufacturing processes or materials.
