Wood treatment device

A wood treatment device comprising:

• a supply of trichloronitromethane;
• a container having an elongate body with a closed end and an opposite open end, the container defining an internal expanse holding the supply of trichloronitromethane, and an open-end section interposed between the internal expanse and the open end, the open-end section defining an open-end passageway providing the only fluid communication through the container between the internal expanse and the open end, the open end passageway having a reduced cross-sectional area compared to the internal expanse, and the container being made of a material that is non-permeable and non-reactive to the supply of trichloronitromethane;
• and
• a plug disposed in the open-end section of the container, filling the open-end passageway, made of a porous material, and having a porous inner face and a porous outer face, wherein the inner face extends across the open-end passageway and is exposed across the inner face to the internal expanse, the outer face faces away from the internal expanse, and the plug is permeable to the supply of trichloronitromethane and is configured to impede passage of the supply of trichloronitromethane through the plug;
• and
• a cap assembly configured to be manually positioned on the open end of the container, the cap assembly including an extension having a blunt end configured to extend through the open-end passageway sufficiently to dislodge the plug from the open-end section and move the plug from the open-end passageway in the open-end section into the internal expanse of the body when the cap assembly is manually positioned on the open end of the container, wherein the extension includes an extension rib extending laterally outwardly along a length of the extension with the extension rib forming a side of an extension channel along the extension, and the cap assembly includes at least one channel allowing less restricted flow of the supply of trichloronitromethane from the open-end passageway to externally of the wood treatment device when the cap assembly is positioned on the open end compared to flow through the plug, and the cap assembly includes a shroud extending around at least a portion of sides of the container along the exterior of the open end when the cap assembly is positioned on the open end of the container and the at least one channel extends between the shroud and the open-end section of the container when the cap assembly is positioned on the open end of the container, the shroud including a shroud rib extending laterally inwardly along a length of the shroud with the shroud rib also forming a side of the one channel along the shroud.
