Evaporative emissions canister partition

A device for capturing and storing evaporative emissions, comprising a housing;

• said housing including a chamber containing a first composite material, a second composite material, and a partition therebetween;
• wherein the partition substantially separates the first composite material and the second composite material;
• and,
• wherein the partition is operable to move within the chamber while maintaining the first composite material substantially separate from the second composite material.

A partition for maintaining a first composite material substantially separate from a second composite material within a chamber, comprising:

• a rigid plate with a plurality of ribs attached thereto;
• wherein the rigid plate is inserted within the chamber along a plane substantially perpendicular to a longitudinal axis of the chamber;
• wherein external dimensions of the rigid plate are slightly less than internal dimensions of the chamber in the plane substantially perpendicular to the longitudinal axis of the chamber;
• wherein the plurality of ribs is operable to maintain the rigid plate substantially perpendicular to the longitudinal axis of the chamber;
• and,
• wherein the partition is operable to move within the chamber.

A method to maintain a first composite material substantially separate from a second composite material, each contained within a chamber, comprising:

• inserting a partition into the chamber between the first composite material and the second composite material;
• wherein said partition is operable to move within the chamber while maintaining the first composite material substantially separate from the second composite material;
• wherein said partition comprises a rigid plate with a plurality of ribs attached thereto;
• wherein the rigid plate fits within the chamber along a plane substantially perpendicular to a longitudinal axis of the chamber;
• wherein external dimensions of the rigid plate are slightly less than internal dimensions of the chamber in the plane substantially perpendicular to the longitudinal axis of the chamber;
• wherein each rib is attached substantially at an outer perimeter of the rigid plate;
• wherein each rib is substantially parallel to the longitudinal axis of the chamber;
• and,
• wherein the plurality of ribs is operable to maintain the rigid plate substantially perpendicular to the longitudinal axis of the chamber.
