Dispenser for air-treating vapors

Abstract

A dispenser for air-treating vapors of the type having lower and upper members adjustable to different vertically spaced positions to control the dispensing of air-treating vapors. The invention includes a lever hinged at one end to the upper member and having a depression surface at its opposite end and further having a lower fulcrum in contact with the lower member midway between the lever ends. The lever serves to raise the upper member to open the device for vapor-dispensing. The fulcrum is preferably a convex cam about which the lever rotates during depression. Certain preferred embodiments include various interacting elements on the lever and the lower member or on the upper and lower members to control and limit the raising of the upper member. In preferred embodiments the hinge is centrally located to provide a generally central lift point for the upper member.
