摘要

A closure is provided. The closure is configured to be coupled to a container having a sidewall extending along a longitudinal axis and defining an open end and an interior. The closure includes a sidewall. The sidewall includes an inner surface and an outer surface. The inner surface includes a coupling feature configured to couple the closure to the sidewall of a container. The closure includes an intermediate wall extending radially inwardly from the sidewall including a first vent aperture. The closure includes an upper closure portion including a second vent aperture. The closure includes a filter layer located between the upper closure portion and the intermediate wall. The closure is configured to prevent gas from travelling in a path generally parallel to the longitudinal axis from the first vent aperture to the second vent aperture.
