摘要： A concentrated reduced dosage spray pump delivery system for dispensing fluids containing actives and volatile organic compounds with reduced emissions of the volatile organic compounds is disclosed. The system includes a housing storing a concentrated fluid containing volatile organic compounds and an effective component, wherein the effective component is concentrated within the fluid. The system also includes a spray pump in fluid communication with the concentrated fluid containing the volatile organic compounds such that the spray pump dispenses the concentrated fluid at a reduced dosage per pump stroke. The combination of the concentrated fluid containing volatile organic compounds and the reduced dosage per pump stroke reduces the emission of volatile organic compounds, while the quantity of actives applied per square area of application surface substantially remains the same.

The pumping engine comprises a reservoir, a closure, and a plunger. The reservoir has an open top and a closed bottom and an interior surface. The plunger has an outer surface and a longitudinal passageway extending therethrough. The plunger further having an outlet valve mounted therein and an upper end and a lower end. The lower end being slidably disposed within the open top of the reservoir forming an interior chamber within the reservoir. The interior chamber has an annular chamber and a main chamber. The annular chamber being in fluid communication with the main chamber. The annular chamber is formed by the outer surface of the plunger being spaced away from the interior surface of the reservoir such that there is no frictional contact between the outer surface and the interior surface. The closure being attached to the open top of the reservoir allowing the plunger to slidably extend through the closure such that the interior chamber is sealingly closed. The nozzle is mounted on the upper end of the plunger such that the longitudinal passageway is in fluid communication with the nozzle. The interior chamber is separated from the longitudinal passageway by the outlet valve.

摘要： The present invention provides an improved atomization system for dispensing and atomizing a fluid product having film-forming characteristics. The atomization system includes a nozzle for atomizing the fluid product which has been formed of a reduced wettability composition including a base material and a wettability-reducing component for reducing the wettability of the base material with the fluid product. The reduced-wettability attribute ensures that the product will tend to "bead up" on the surfaces of the nozzle assembly rather than wetting or coating the surfaces. The surfaces will thus tend to repel the product, once the supply pressure driving the fluid toward the nozzle is relieved, leaving the critical nozzle surfaces substantially free of a film of product which would tend to dry and form a residue on the critical nozzle surfaces when exposed to atmospheric air. The reduced wettability of the nozzle assembly is preferably achieved through the addition of a melt additive to impart the desired characteristics to the nozzle base material. Improved atomizer nozzles according to the present invention also preferably incorporate a change in cross-sectional area of the nozzle passages to further enhance the migration of the fluid away from the nozzle orifice once the supply pressure is relieved utilizing capillary pressure phenomena.
摘要翻译： 本发明提供了一种用于分配和雾化具有成膜特性的流体产品的改进的雾化系统。 雾化系统包括用于雾化已经由包含基材的降低的润湿性组合物形成的流体产品的喷嘴和用于降低基体材料与流体产品的润湿性的润湿性降低组分。 降低润湿性的特性确保产品将倾向于在喷嘴组件的表面上“起珠”，而不是润湿或涂覆表面。 因此，一旦释放向喷嘴驱动流体的供应压力，表面就会排斥产品，使得临界喷嘴表面基本上没有产品的薄膜，该薄膜将倾向于在临界喷嘴表面上干燥并形成残留物，当时 暴露于大气中。 喷嘴组件的降低的润湿性优选通过添加熔融添加剂以赋予喷嘴基材所需的特性来实现。 根据本发明的改进的雾化喷嘴还优选地包括喷嘴通道的横截面面积的变化，以在利用毛细管压力现象减轻供应压力后进一步增强流体远离喷嘴孔的迁移。

摘要： The present invention provides a manually operated dispensing system for dispensing a liquid product in atomized or foam form. More particularly, the present invention provides an improved manually operated pump to for use in such dispensing systems which incorporates at least one collapsible bellows as a pump chamber. The use of a bellows as the air chamber in an air/liquid pump mechanism allows the pressure/volume profile of the air supply to be tailored to supply the desired air/liquid ratio throughout the travel of the pump mechanism. The shape of the air bellows is preferably selected to provide an is initially large volume reduction in the air chamber as the bellows collapses to provide a rapid rise in air pressure available for dispensing. In a preferred embodiment, dual bellows are utilized (one for liquid, one for air) in a concentric arrangement to allow the pressure/volume profile for each to be tailored to achieve the desired spray or foam characteristics. Inlet and outlet valves are unitarily formed with the liquid bellows and the use of a pre-compression mechanism for the liquid outlet valve allows the air pressure to build to the level required for satisfactory performance before the liquid begins to flow.

摘要： Disclosed is a spray package having a container body, an actuator, and a shroud between the container body and the actuator. The actuator has a nozzle, and is adjustable between a locked position and an unlocked position by rotation of the nozzle about the actuator's longitudinal axis. The unlocked position allows vertical movement of the actuator for dispensing product from the package, and the locked position prevents vertical movement of the actuator to prohibit dispensing of product from the package. The locked position simultaneously provides cooperation between the nozzle and an anti-clog member, connected to and extending above the shroud. The anti-clog member has a nozzle seal on its inside surface which inhibits clogging of product within and about the nozzle when the seal is in contact with the nozzle.

摘要： A foam dispensing system for a foamable liquid has a means for producing a spray of droplets in which the spray of droplets has key parameters of: the number averaged mean diameter and the mean axial droplet velocity. The foam dispensing system also has a foaming nozzle connected to the means for producing a spray of droplets that is placed in fluid communication with the spray of droplets. The foaming nozzle has a screen which has a plurality of screen openings having a mesh range from 30 to 60 openings per linear inch. Key parameters of the screen are: the percent open area is from about 35% to 60% and the screen openings are larger than the number average mean diameter of the spray of droplets. When the mean axial droplet velocity is at least 8 m/s, the spray of droplets is transformed into a foamed spray as the droplets pass through the plurality of screen openings.
