One or more of the outlet ports is angled away from a plane normal to the axis of the fluid delivery head. | 11-20-2008 |
20080305978 | Cleaning compositions containing a hydrophilic fragrance - Cleaning compositions for hard glossy surfaces having reduced streaking and blooming based on the inclusion of a compatible fragrance or fragrance mixture therein is described. Compatible fragrance(s) are hydrophilic fragrances having a Delta value of 22 or less. The fragrance is maintained in solution in the absence of a solubilizer fragrance carrier. | 12-11-2008 |
20080318176 | Fuel element for melting plate candle assembly - A fuel charge for use with a melting plate candle assembly includes an outer shell of fuel material surrounding an inner core of fuel material having different properties than the fuel material of the outer shell. The outer shell is substantially solid and may contain fuel additive that slows capillary flow of liquid fuel to the flame through the wick. The inner core may include liquid fuel, discrete solid fuel particles, or a solid fuel mass. The fuel additive is disposed in the fuel charge so as to slow migration of liquefied fuel to a flame on a wick only after a substantial portion of the fuel charge has been liquefied by heat from the flame. | 12-25-2008 |
20090078793 | Fluid Dispensing Nozzle - A nozzle is provided for dispensing a liquid from a container in a desirable, nearly rectangular spray pattern. The nozzle includes an actuator having an inlet end adapted to receive liquid from the container and an outlet end, the actuator outlet end defining an outlet chamber. An insert is coupled to the actuator outlet end and defines an insert passage in fluid communication with the outlet chamber. The insert includes at least a first convex shoulder disposed downstream of the outlet chamber, and a nozzle outlet disposed downstream of the first convex shoulder. The convex shoulder may have a radius of curvature and side walls may be provided at an angle of convergence. The radius of curvature and the angle of convergence may be provided within certain ranges to obtain the desired spray pattern at the desired flow rate using typical aerosol can pressures. | 03-26-2009 |
20090205152 | Refill for a Cleaning Implement - A cleaning implement is disclosed which is of the all-in-one type. It has a substrate that delivers impregnated cleaning liquid to the window being cleaned, a squeegee blade to drive used cleaning liquid off the window, and an absorbent region of the substrate to collect the used liquid. In some embodiments a single block of substrate can provide the applicator, scrubbing, and collecting functions, as well as filter and reprocess used cleaning liquid for further use. Refill structures are provided to permit insertion of the refill in varied directions, to facilitate insertion and removal of the refill, to increase the abrasive character of the refill, to minimize drooling, and to otherwise optimize cleaning properties of the refill. | 08-20-2009 |
20090311148 | Heated Volatile Dispensing Device With Use-Up Indicator - Heated volatile dispensers are disclosed that are provided with automated use-up indicators. The indicators are associated with a porous substrate. A migrateable dye is covered by meltable material adjacent the substrate. Heating of a substrate such as a slab impregnated with an insect repellent both causes the insect repellent to dispense and melts the covering. The dye then migrates to a visible surface of the substrate to indicate a degree of use. The extent of migration, and the patterns formed on the visible surface by the migrating dye, indicate the extent to which the volatile air treatment chemical has been dispensed. | 12-17-2009 |
20100206960 | Volatile Liquids Having Predetermined Evaporation Profiles - Dispensers and refills for volatile liquids, such as fragrances, are disclosed. Dispensers and refills in combination with dispensers according to the present invention may comprise a volatile liquid and a housing. In certain embodiments, the volatile liquid of the present invention has a predetermined evaporation rate, measured and calculated by the method described herein. In other embodiments, the volatile liquid exhibits a predefined relative evaporation rate. In addition to the housing, the present invention includes optional components, such as a motorized fan and/or a wick, to facilitate release of the volatile liquid into the atmosphere. | 08-19-2010 |
20110220731 | Air Treatment Device With Controlled Pore Size Substrate - Disclosed are substrates suited for dispensing air treatment chemicals upon being heated. Granular particles, preferably sand with a phenolic binder, are adhered together to form a substrate body having a network of pores. A volatile air treatment chemical is disposed in the pores. The particle size and pores are such that the smaller particles of the substrate are grouped at one end, preferably an end adjacent to a projecting nose. This structure tends to wick the volatile air treatment chemical towards the nose, and heating that area can lead to efficient, and rechargeable, dispensing. Methods for using such substrates, and methods for forming such substrates, are disclosed. | 09-15-2011 |
20120131986 | METHODS AND APPARATUS FOR TESTING AIR TREATMENT CHEMICAL DISPENSING - Disclosed herein are methods for measuring the concentration of volatile air treatment chemicals in the air. These methods can be used to evaluate the effectiveness of, and/or optimize, dispensers that dispenses a volatile air treatment chemical into a test area. One runs side by side sampling of air using both sorbent tube and solid phase micro extraction fiber collectors to develop a correlation curve between air treatment chemical concentration results from the sorbent tube sampling and amount readings from the SPME sampling. One then uses SPME collectors to measure in a passive manner the performance of the volatile dispensers. | 05-31-2012 |
