Abstract: A beverage system includes a vessel having a chamber for retaining a volume of diluent such as water, and at least one assembly for expressing aliquots of flavor concentrate from a flavor concentrate cartridge into the diluent. Flavor concentrate is expressed from the cartridge by actuating a sliding pawl that moves a ratchet bar to depress a plunger on the cartridge. Cartridges of flavor concentrate are inserted into the beverage system and spent cartridges are removed upon depletion. In this manner a user can customize the volume and ratio of flavor and additives in their beverage.

Abstract: A shower apparatus includes: a mounting bracket or mounting component; and a rigid component or shower panel. The shower panel includes one or more spray arrangements of sprayers, spray arrays, or spray patterns, and fluid passageways connecting water input to the one or more spray arrangements. The shower apparatus further includes a water flow control assembly for selecting a single flow from a plurality of flows to different combinations of the spray arrangements. The water flow control assembly comprises a plurality of buttons, a constrained strip, and a plurality of valves. A button when selected deflects the constrained strip—which is constrained and capable of deflection at a single location—into a corresponding valve to activate flow through the valve. This deflection straightens a previous deflection, thereby closing the previously open valve.
