Abstract: A trigger pump sprayer in combination with a liquid dispensed from the sprayer. The sprayer is suitable for dispensing liquid from a reservoir, through a nozzle into particles. The trigger sprayer provides for efficacious particle size distributions of the liquids, when sprayed under non-ideal conditions. Non-ideal conditions include only partial strokes of the trigger, rather than full strokes and relatively slow trigger strokes. The trigger sprayer advantageously delivers a particle size distribution suitable for liquids having particular rheological properties. The advantageous particle size distribution difference is accomplished by using a precompression piston which reciprocates in response to trigger strokes, and selecting a liquid having appropriate properties to correspond to the trigger pump operating characteristics.

Abstract: A trigger pump sprayer in combination with a liquid dispensed from the sprayer. The trigger sprayer provides for efficacious particle size distributions of the liquids, when sprayed under non-ideal conditions. Non-ideal conditions include only partial strokes of the trigger, rather than full strokes and relatively slow trigger strokes. A bimodal distribution of particle sizes is obtained under two different operating conditions. The sprayer/liquid combination according to the present invention compresses the difference between the two modes, without requiring undue work by the operator. The advantageous particle size distribution difference is accomplished by using a precompression piston which reciprocates in response to trigger strokes, and selecting a liquid having appropriate properties to correspond to the trigger pump operating characteristics.

Abstract: The present invention relates to a cleaning implement comprises a handle; a head portion pivotally attached to the handle comprising an upper surface and a lower surface connected to the upper surface by side edges; and a cleaning pad removably attached to the head portion, the cleaning pad comprising an absorbent layer which extends over the lower surface of the head portion and a scrubbing strip which extends along a side edge of the head portion.

Abstract: A plural nozzle cleaning implement. The nozzles are oriented inwardly, to provide a converging spray pattern. The converging spray pattern provides more coverage of the target surface, which increases residence time of fluid sprayed onto debris.

Abstract: A plural sided duster removably attachable to a handle. The duster may have two construction portions, each with an inwardly facing surface joined to the other to form a laminate construction. The construction portions may be longitudinally offset. The arrangement allows an attachment mechanism associated with the inwardly facing surface to be visible to the user, so the handle may be easily and removably attached to the duster at the attachment mechanism.

Abstract: A pressurized package for dispensing product there from through a valve. The valve is attached to the package by a valve cup. The valve cup is plastic, eliminating the need for metallic deformation to maintain pressurization of the container having propellant therein. This arrangement provides the benefit of less expensive package assembly.

Abstract: An air treatment device having a piezoelectric actuator powered by a transformer. The transformer has dual inputs comprising oppositely wound coils and input power signals 180 degrees out of phase. This arrangement provides a stronger drive signal to the actuator.

Abstract: A cleaning implement having a dirt bin for collecting debris from a floor. The dirt bin has at least one of a cleaning sheet and/or air filter attached thereto, as presented to the user. This arrangement allows for more efficient disposal of debris from the dirt bin and soiled components. The dirt bin may be emptied and reused or may be discarded after a single use.

Abstract: The present invention relates to a container for dispensing vertically configured wipes, which provides improved sequential dispensing of the contained wipes while permitting enhanced accessibility to the wipes within the container.

Abstract: A method and apparatus for applying indicia to a curved surface, including a compound curved surface having multiple axes of curvature. The curved surface is deformed to eliminate one axis of curvature. The invention is usable with hourglass or barrel shaped surfaces, as occur with containers, and to apply labels and other indicia to these surfaces.
