Abstract
A docking sleeve is provided for insertion into a bore in the side of a work-piece. A sealed chemical-holding cylinder is passed through the docking sleeve into the bore and an actuator is screwed into the docking sleeve to pierce a seal of a the cylinder so that chemicals contained therein can vaporize and treat the inside of the work-piece.
Claims18
A wood-treating device comprising
- a docking sleeve having top and bottom ends and having a continuous aperture extending through both ends;
- a container for holding treating materials dimensioned to extend through the aperture and adapted to be removably mounted to the docking sleeve, the container having an elongate tubular body portion with an open end adjacent the docking sleeve and a closed end opposite the open end and having an enlarged head portion adjacent said open end extending radially outwardly from said body portion to define a support collar;
- a frangible seal covering the opening;
- and
- an actuator mounted for shifting in the docking sleeve toward the seal operable to break the seal.

A container for holding materials for treating wood products comprising
- an elongate tubular body portion having an open end and a closed end,
- an enlarged head portion on said open end extending radially outwardly from said body portion to define a support collar, said collar has a first surface facing toward said closed end of the body portion and a second surface facing in the opposite direction and an opening extending through said collar from said first surface to the second surface to permit fluid to pass therethrough exteriorly of the container from said open end toward the closed end thereof, wherein said opening is spaced radially outwardly of the outer surface of said body portion, and
- a frangible seal extending over said open end adjacent said collar to retain treating materials in said container until said frangible seal is broken.

- a frangible seal of gas impermeable sheet material extending over said open end adjacent said collar to retain vaporous treating materials in said container until said frangible seal is broken, said seal being removably secured to an exposed end surface of the body portion permitting a broken seal to be removed and replaced with an unbroken seal upon recharging of the container for re-use.
A wood-treating device comprising
- a docking sleeve having top and bottom ends and having an aperture extending through both ends, the docking sleeve adapted to be mounted within a bore of a work-piece;
- a container for holding treating materials dimensioned to extend through the aperture and adapted to be removable from the docking sleeve while the docking sleeve is mounted within the bore of the work-piece, the container having an elongate tubular body portion with an open end adjacent the docking sleeve and a closed end opposite the open end and having an enlarged head portion adjacent said open end extending radially outwardly from said body portion to define a support collar;
- a frangible seal covering the opening;
- and
- an actuator mounted for shifting in the docking sleeve toward the seal operable to break the seal.
