ABSTRACT:
A deodorant dispensing package having two rates of discharge of deodorant. The package is provided with air circulation ports for a low, continuous release of deodorant and a manual pump for a high, forced rate of deodorant discharge for sudden odors. The package is formed of two telescoping housing members with an internal wall portion that divides the housing into inner and outer compartments. The housing contains a deodorant reservoir and the inner and outer compartments are each provided with vent ports communicating externally of the housing. The inner and outer compartments also communicate through an interior port in the internal wall and a deodorant discharge surface is located in the inner compartment between the inner port and the inner compartment external vent port. Air circulation through the vent ports is sufficient to provide the low rate of air freshener activity. The manual contraction and expansion of the telescoping housing members provides a high rate of deodorant discharge. Preferably a bellows is provided in the outer compartment to facilitate the pumping action. Also preferably, the vent port from the inner compartment is provided with variable aperture means whereby its degree of opening can be fixedly adjustable. The package is intended for use with replaceable canisters of deodorant which can be in liquid form, impregnated or incorporated in a gel solid, or absorbed in a sponge or other carrier.
