A bulk-solid metering system has a support structure. A feed hopper is mounted with respect to the structure and has an upper edge. In the improvement, the structure includes an upper member and the upper edge is below such upper member. The structure defines a lateral opening sized and shaped to permit the feed hopper to be withdrawn laterally through the opening. The feed hopper includes a spout extending therefrom. In a highly preferred embodiment, the lateral opening is positioned to permit withdrawal of the feed hopper in a direction away from the spout. The feed hopper is configured to promote very good mass flow as well as to permit agitation in that, in one embodiment, it has a body made of flexible material. There is a hopper upper flange and the spout is spaced below such flange. The body has a first cross-sectional shape, e.g., circular, adjacent to the upper flange and has a second cross-sectional shape, e.g., ellipse-like, intermediate the upper flange and the spout.

A rechargeable spray bottle dispensing apparatus, comprising: a spray bottle including a first neck portion; a spray head connected to the first neck portion of the spray bottle, the spray head including a downtube; an insert having at least one reservoir configured for containing at least one dose of chemical concentrate; and a probe cooperating with and actuated by the spray head, the probe configured for selectively releasing contents of said at least one reservoir of the insert into the spray bottle, the probe being configured to accommodate the downtube of the spray head, and the probe being located off axis relative to the downtube and oriented substantially parallel with the downtube. 19. The apparatus of claim 18 wherein the probe comprises: a connecting portion for attaching the probe to a barrel of the spray head; a disc portion, the connecting portion and the disc portion defining a through hole; and a shaft portion connected to the disc portion at one end and defining a tip end at another end. 20. The apparatus of claim 19 wherein the spray head includes a movable piston and wherein the connecting portion comprises: a first cylindrical portion having an outside diameter, the first cylindrical portion being inserted into the barrel to form a non-locking press fit with an interior of the barrel; and a second cylindrical portion having an outside diameter larger than the outside diameter of the first cylindrical portion, the second cylindrical portion forming a stop against the barrel; wherein the downtube is inserted in the through hole of the disc and connecting portions and attached to the movable piston. 21. The apparatus of claim 20 wherein the disc portion includes a stiffener ring disposed on a lower surface of the disc portion. 22. The apparatus of claim 21 wherein an outside diameter of the stiffener ring is smaller than an outside diameter of the disc portion. 23. The apparatus of claim 21 further comprising at least two ribs extending from an inside of the stiffener ring to the through hole, the at least two ribs being disposed on opposite sides of the shaft portion. 24. The apparatus of claim 19 wherein the connecting portion is generally cylindrical, an interior surface of the connecting portion forms a non-locking press fit with an exterior surface of the barrel, the downtube is inserted in the through hole of the disc and connecting portions and the downtube is attached to the barrel. 25. The apparatus of claim 19 wherein the probe further comprises a generally cylindrical downtube insertion portion disposed on a lower surface of the disc portion and wherein the connecting portion is generally cylindrical, an exterior surface of the connecting portion forms a non-locking press fit with an interior surface of the barr
