Moondyne Bottle Cap Spring Flipper Cap M41L0001-1BK

A worn or missing lid turns a reliable insulated bottle into a liability on site. This Moondyne spring flipper cap restores the original function so the vessel seals properly and opens with one hand while the other stays on the wheel, the tools or the job at hand.

The flipper mechanism snaps open under thumb pressure and locks back against the collar, giving a wide mouth for fast drinking or easy ice loading. When released, the internal spring returns the lid to a positive closed position that resists vibration and knocks common in utes, plant cabins and workshop benches. The pivot pin is moulded into the cap body, removing a separate loose part that can fall out during cleaning. The seal seats against the bottle neck without cross-threading, so refill cycles stay quick through a long shift.

Suits Moondyne thermal mug and bottle ranges that share the same neck finish. Order this cap when the original hinge fatigues or the seal no longer holds pressure.
