Product dispenser with an s-shaped down chute

A serpentine product dispenser with a top, a bottom, a front, a back, a first side, and a second side, for dispensing cans having a radius from a cartridge containing a lower first row of cans and at least one upper row of cans positioned above the lower first row of cans, the dispenser comprising:

• a) a loading ramp disposed between the first side of the dispenser and the second side of the dispenser near the top of the dispenser, having a first end located near the front of the dispenser and a second end located a distance from the back of the dispenser, the second end of the loading ramp forming an exit port first end, the first end of the loading ramp being higher than the second end of the loading ramp, such that the loading ramp forms an angle relative to a horizontal, biasing cans in the cartridge located on the loading ramp to roll toward the back of the dispenser;
• b) a back wall forming an exit port second end separated by at least one can diameter from the exit port first end, disposed between the first side of the dispenser and the second side of the dispenser at the back of the dispenser, limiting rearward motion of the cartridge on the loading ramp;
• c) an exit port between the exit port first end and exit port second end, aligned with an aperture in the cartridge on the loading ramp, such that a can may exit the cartridge through the aperture and pass through the exit port;
• d) a down chute disposed between the first side of the dispenser and the second side of the dispenser near the back of the dispenser and below the exit port, comprising:
• i) an upper arcuate section with a first end adjacent to the back wall of the dispenser, a second end, and a first radius of curvature therebetween, the first radius of curvature being convex toward the top of the dispenser and the front of the dispenser;
• ii) a central arcuate section with a first end adjacent to the second end of the upper arcuate section, a second end, and a second radius of curvature therebetween, the second radius of curvature being concave away from the top of the dispenser and the front of the dispenser;
• and
• iii) a lower arcuate section with a first end adjacent to the second end of the central arcuate section, a second end, and a third radius of curvature therebetween, the third radius of curvature being concave away from the top of the dispenser and the front of the dispenser;
• wherein the upper convex arcuate section forms a rolling surface extending downwardly and forwardly from the exit port second end;
• such that, when a first can is moving through the exit port in rolling contact with the upper convex arcuate section, the first can is guided toward the exit port second end by the upper convex arcuate section such that the first can is in rolling contact with a second can from the lower first row of cans in the cartridge, thereby inhibiting movement of the second can toward the exit port, such that when the first can is in rolling contact with the central arcuate section, the first can remains in rolling contact with the second can from the lower first row, thereby continuing to inhibit movement of the second can toward the exit port as the first can rolls on the central arcuate section, and such that a can moving along the lower arcuate section is directed toward the bottom of the dispenser and the front of the dispenser.
