Abstract
Abstract Method and apparatus for dispensing detergent from within a container (2) comprises directing a water spray transversely of the container (2) vertical orientation to dissolve and remove detergent in solution from the container (2). The transverse direction of water spray greatly improves detergent dispensing performance and minimize clogging of the system during down times.

Claim 1
Independent Claim
215 words
A dispenser for receiving an dispensing granular detergent from a container, comprising: (a) a support for supportably receiving an inverted container of granular detergent; (b) a container for holding and dispensing granular detergent, having a head portion which is lowermost of said container as inverted and positioned in and extending vertically in said support, said head portion having an aperture formed therein which opens laterally of said head portion and extends transversely of said vertically extending container; (c) means for injecting and directing a horizontal stream of water into said container to dissolve granular detergent in said head portion, said water injecting means extending through a portion of said support adjacent and spaced apart from said container head portion aperture, whereby said water injecting means directs a horizontal stream of water into said aperture; and (d) said container head portion having a bottom in which an outlet is provided, said outlet comprising a plurality of louvres traversing said outlet to define a mesh which substantially retains granular detergent in said container and which permits dissolved granular detergent to pass through said outlet; wherein the support further comprises an overflow which is dimensioned such that the vertical distance between the water surface in the overflow and the water injection point is always at least 40 mm.
