The container includes a locking surface on the neck spaced from the opening. The tamper-evidencing band includes an inwardly turned retaining rim that extends at least partially upwardly. The retaining rim has a free edge for engagement with the locking surface as the closure is removed from the neck.

Drain passageways are provided in the rim to enable draining and/or evaporation of trapped liquid.
