ABSTRACT:
A dispensing container for an air treating gel comprising: (A) a base member of relatively flat and circular contour having a raised circular gel-supporting surface having a first stem located at the center of the surface projecting vertically upward therefrom, said first stem having a relatively short upper portion having a substantially smaller diameter than the remaining longer lower portion, said surface having a cylindrical side wall providing a lip portion about the circumference of said surface, said wall being integrally connected at its lowermost portion to the lowermost portion of a second cylindrical wall laterally offset therefrom to provide an annular recess about the circumference of said surface; (B) a top member of relatively flat and circular contour having a cylindrical side wall disposed about its circumference, said top member having a second central hollow stem for insertion therein of the upper portion of said first stem; and (C) a tubular-walled member capable of slideably engaging the outer surface of the top side wall member while the base member first stem and top member second stem remain fixedly engaged, whereby the vertical displacement of the lowermost edge of said tubular-walled member relative to the base member can be varied to obtain a plurality of open positions and can be adjusted to a fully closed position when said edge is caused to be inserted into said annular recess to provide a vapor-tight seal. Additionally, the dispensing container is capable of functioning as a refill for a room deodorizer having a bottom portion of generally cylindrical shape and a closure of generally frusto-conical shape which is adjustable with respect to the bottom by means of a mating hollow bottom post and closure post which frictionally engages the inner surface of the hollow bottom post.
