What is a 38mm Water Bottle Sport Lid?

A 38mm water bottle sport lid is a specially designed beverage closure installed on bottles with a 38-400 neck finish. Different from traditional bottle caps, this sport lid integrates a silicone valve system inside the cap, providing a self-sealing dispensing function. The silicone valve remains closed when the bottle is not squeezed, preventing liquid leakage during transportation or storage. When users apply pressure to the bottle, the valve opens smoothly and allows controlled liquid flow.
