Abstract

A serpentine product dispenser has a substantially “S”-shaped down chute between a cartridge containing rolling products, an exit port, and a lower feed channel leading to a product selection area. Jam-free feeding of cans from the cartridge is accomplished by forming the down chute in three arcuate sections. An upper arcuate section causes a first can falling through the exit port to impact a second can still in the dispenser, delaying motion of the second can, such that a third can follows the first can. A central arcuate section causes the first can to maintain rolling contact with a second can still in the cartridge, further facilitating the movement of the third can toward and into the down chute. A lower arcuate section directs cans toward the dispenser lower feed ramp and product selection area after they traverse the down chute upper and central arcuate sections.

First claim

What is claimed is:

1. 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.

2. The serpentine product dispenser of claim 1 , in which the angle formed by the loading ramp relative to the horizontal is eight degrees or less.

3. The serpentine product dispenser of claim 1 , wherein the cartridge is a hopper volume enclosed by at least the back of the dispenser and the loading ramp.

4. The serpentine product dispenser of claim 1 , wherein the second radius of curvature of the central arcuate section of the down chute is approximately three times the radius of a can contained in the cartridge.

5. The serpentine product dispenser of claim 4 , wherein the cartridge is made from a material with a thickness, and the radius of curvature of the central arcuate section of the down chute is increased by at least the thickness of the material of the cartridge.

6. The serpentine product dispenser of claim 1 , wherein the radius of curvature of the central arcuate section of the down chute has an origin located above the loading ramp a distance approximately equal to the radius of a can contained in the cartridge, and forward of the back wall a distance of approximately three times the radius of the can.

7. The serpentine product dispenser of claim 6 , wherein the cartridge is made from a material with a thickness, and the location of the origin of the radius of curvature of the central arcuate section of the down chute is offset by at least an amount equal to the thickness of the material of the cartridge.

8. A 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 hopper volume arranged as 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 hopper volume located above 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;
c) an exit port between the exit port first end and exit port second end, such that a can may 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;
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 arcuate section, the central arcuate section, and the lower arcuate section combine to form a downwardly and forwardly rolling surface extending downwardly and forwardly from the exit port second end; such that, when a first can from the lower first row of cans moves 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, 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 sec
