Morphology
The noun phrase 'tight cap' is directly and transparently composed from 'tight' (closely fitted) modifying 'cap' (a lid); the sense 'a cap that fits securely to prevent leakage' follows immediately from normal adjective + noun composition. This is a common, predictable pattern across languages and would be easily understood by a B1 learner who knows both constituent words.
Etymology
Tight cap comes from the simple image of a cap that is very tight on a bottle or jar. A cap that holds on like that stops things from leaking or spilling, so tight cap now means 'a cap that prevents leaking or spillage'.
