Method and device for delivery and confinement of surface cleaning composition

摘要

A device and means for applying a thickened cleaning composition to a selected surface area that minimizes or eliminates any unintentional or excess application of the composition and/or minimizes or eliminates any spreading or wicking of the composition beyond the selected surface area after application is disclosed. The dispensing device features a combination of a thickened cleaning composition having a specified rheology and dispensing means with one or more orifices of preferred cross-sectional area that enable convenient application of a cleaning composition to the selected region of a soft or hard surface. Additionally, the dispensing device features cleaning compositions having preferred wicking rates with respect to the treated surfaces so that only the selected stained or soiled region of the surface is effectively treated, as the cleaning compositions will not spread or wick into adjacent regions of the surface where damage may occur. Particularly disclosed is a device for delivering a thickened cleaning composition comprising: which comprises: (a)an applicator; and (b) at least one overcap; wherein said applicator comprises: (i) a chamber containing a thickened cleaning composition comprising an oxidizing agent selected from the group consisting of a hypohalite, a hypohalite generator, a peroxygen bleach, and combinations thereof; and (ii) at least one orifice for dispensing said thickened cleaning composition, wherein said orifice has a surface area of between 0.08 mm2 and 4 mm2; (c) wherein said thickened composition is dispensed by applying pressure to said applicator; (d) wherein said thickened cleaning composition has a viscosity greater than 2000 cP as measured using a Brookfield model DVII viscometer with spindle 2 at 10 rpm; and (e) wherein said thickened cleaning composition has a wicking diameter after 15 min. of less than 20 mm on 100% mercerized cotton broadcloth fabric (composition having a wicking rate after 15 min. between 0 to 1.0 mm/min on 100% mercerized cotton broadcloth fabric).
