Abstract: A hanger for supporting a toilet tank chemical dispensing apparatus which attaches to the top edge of the tank and which incorporates a tilt compensating feature to accommodate non-vertical toilet tank walls. The dispenser is preferably so mounted on the inner leg of a generally U-shaped hanger which contacts the innermost surface of the toilet tank wall as to be vertically adjustable. The outer leg of the hanger contacts the outermost surface of the toilet tank wall at a pivot point. Resilient means, which direct a force between the inner leg and the inside surface of the toilet tank wall at a point above the pivot point, coact with the pivot point to produce a coupled force system. The coupled force system causes the hanger and dispenser adjustably secured thereto to rotate about the pivot point into a position in which the lowermost end of the dispenser is held adjacent the tank wall, thereby maintaining the dispenser as close to vertical as is feasible despite the tilt inherent in the toilet tank wall.
Abstract: A passive dosing dispenser for issuing, for example, a predetermined volume of a toilet tank additive solution into a toilet tank as the water is draining therefrom while the toilet is flushing. A preferred dispenser comprises a product chamber for containing a quantity of a solid type product which can be dissolved in water to form a toilet tank additive product solution, a reservoir for containing a quantity of said solution in fluid communication with said product chamber, an inlet/discharge conduit having its lowermost end in fluid communication with said reservoir and its uppermost end in fluid communication with a syphon tube, an air trap disposed adjacent said inlet/discharge conduit for isolating said product solution from the toilet tank water in said syphon tube during quiescent periods, and an air vent in fluid communication with said reservoir and product chamber.
Abstract: A passive dosing dispenser for issuing, for example, a predetermined volume of a toilet tank additive solution into a toilet tank as the water is draining therefrom while the toilet is flushing. A preferred dispenser comprises a reservoir for containing a quantity of a toilet tank additive type product and in which reservoir a solid type product can be dissolved to form a product solution. In operation, while the water in the toilet tank is receding from about the dispenser, a predetermined dose-volume of toilet tank water is vacuum-transferred into the reservoir through an inlet conduit, and a substantially equal dose-volume of the product solution is dispensed through a discharge standpipe. The dispenser may further comprise an internal baffle to precipitate mixing and agitation inside the dispenser which promote dissolution.
Abstract: A dispensing package comprising a substantially rectangular, parallelepipedal container which is suitable for stacking, a bag-type liner, and an internal funnel having its outlet end disposed adjacent a sidewall of the container so that the contents of the container can be dispensed through its side as opposed to the flap formed, multiple layered top or bottom closure is disclosed. The funnel is provided with a sufficient degree of taper that substantially all of the flowable material contained within the bag liner can gravitate from the package when the package is oriented with the funnel pointing downardly and the portions of the bag liner and the carton sidewall which span the outlet end of the funnel are breached.
Abstract: A fluid injector for the introduction, dispersion and mixing of a first fluid into a second fluid flowing through a conduit. The injector comprises an elongated body mounted in fluid-tight fashion through an aperture in the side of the conduit so as to extend transversely of the interior of the conduit and transversely of the flow of the second fluid therein. The injector body has an axial bore connectable at one end to a source of the first fluid under pressure and leading to at least one outlet bore extending transversely of the injector body and located within the conduit. The injector body has a transverse inlet bore within the conduit. One end of the inlet bore faces the flow of the second fluid within the conduit and the other end thereof communicates with the axial bore of the injector body upstream of the at least one outlet bore.
