Abstract
An improved bottle brush includes a brush, a squeeze bottle having an internal cavity and a feed tube of predetermined configuration extending from the brush into the internal cavity of the bottle. A liquid cleaning agent partially fills the internal cavity and partitions it into a region of liquid and a superadjacent region of foam. The foam is produced initially by shaking the bottle and is maintained automatically by the shaking action of scrubbing. The bottle brush is usable in a foam-feed and a liquid-feed mode, and the predetermined configuration of the feed tube is determined such that it opens into the region of foam when used in the foam-feed mode and opens into a region of liquid when used in the liquid-feed mode. In either mode, foam or liquid respectively is controllably dispensed without wastage of the liquid cleaning agent by gently squeezing the bottle. A conversion element is disclosed for converting a conventional liquid-feed bottle brush into one that feeds liquid and foam in accord with the present invention.
