Liquid Storage Container With Discontinuous Thread

The male thread portion is divided into multiple discontinuous segments around the periphery of the coupling portion, rather than forming a continuous ring. This segmentation allows the thread structure to absorb and distribute impact forces across multiple discrete points, preventing catastrophic failure while maintaining sealing capability through the combined effect of all thread segments.

The thread portion is strategically positioned only at specific locations around the coupling portion rather than uniformly across the entire periphery. This local placement optimizes the balance between providing sufficient sealing contact points and maintaining overall structural integrity under impact, concentrating sealing function where needed while preserving strength in other areas.

The continuous thread structure is segmented into multiple discontinuous portions, which prevents stress concentration and crack propagation under impact. Each segment independently contributes to sealing while the gaps between segments act as stress relief zones, reducing the likelihood of cover deformation and breakage during dropping or impact events.

The discontinuous thread design inherently provides structural cushioning by creating flexible zones between thread segments. These zones allow controlled deformation under impact before reaching critical failure points, effectively cushioning the cover member against impact damage while maintaining sealing integrity through the resilient thread segments.
