摘要

An emissions device for use with a container assembly with a vent opening is provided. The emissions device includes a housing configured to be mounted to the container. The housing includes a backing plate that has at least one opening. A membrane is supported by the backing plate and extends over the opening. The membrane is configured to allow passage of vapor and prevent passage of liquid. A filter is located within the housing such that vapor that passes from the at least one opening through the membrane then passes through the filter. At least one spring is positioned within the housing and is configured to compress the filter.

1. An emissions device for use with a container that has a vent opening, the emissions device comprising:
a housing configured to be mounted entirely inside of the container around the vent opening, wherein the housing includes a backing plate that has at least one opening; a membrane supported by the backing plate and extending over said at least one opening, wherein the membrane is configured to allow passage of fuel vapor and prevent passage of liquid fuel; a filter located within the housing such that fuel vapor passing from said at least one opening through the membrane then passes through the filter; at least one spring positioned within the housing; a compression plate positioned between said at least one spring and the filter and having a width substantially equal to a width of the filter; wherein said at least one spring presses against the compression plate such that the compression plate compresses a depth of the filter.
