A canister for dispensing an article of a predetermined size and shape, comprising: a. A screw, said screw having a distal and a proximal end; b. A cradle having a proximal and a distal end into which said screw is removably mounted; c. A hollow body having a base surface, said body adapted to receive said screw mounted in said cradle and position of said screw in a position generally parallel to said base surface wherein: i. the distal end of said screw and cradle combination abuts a distal wall of said body, and ii. a proximal end of said screw and cradle combination abuts an aperture in a proximal wall of said body; and d. A rotational driver-coupling mounted to the proximal end of the screw, the canister being characterized by A. A channel on the external surface of said screw, said channel being of a predetermined width and depth corresponding to the dimensions of said article; B. A singulation blade mounted within said body near the proximal end of the cradle; and C. A removable shelf mounted to at least one interior side of said cradle, wherein at least a portion of said shelf is positioned: i. near the proximal end of said screw and cradle combination; and ii. corresponding to the dimensions of said article, so that said screw channel and said shelf encase a portion of said article: a. A screw, said screw having a distal and a proximal end; b. A cradle having a proximal and a distal end into which said screw is removably mounted; c. A hollow body having a base surface, said body adapted to receive said screw mounted in said cradle and position of said screw in a position generally parallel to said base surface wherein: i. the distal end of said screw and cradle combination abuts a distal wall of said body, and ii. a proximal end of said screw and cradle combination abuts an aperture in a proximal wall of said body; and i. the distal end of said screw and cradle combination abuts a distal wall of said body, and ii. a proximal end of said screw and cradle combination abuts an aperture in a proximal wall of said body; and d. A rotational driver-coupling mounted to the proximal end of the screw, the canister being characterized by A. A channel on the external surface of said screw, said channel being of a predetermined width and depth corresponding to the dimensions of said article; B. A singulation blade mounted within said body near the proximal end of the cradle; and C. A removable shelf mounted to at least one interior side of said cradle, wherein at least a portion of said shelf is positioned: i. near the proximal end of said screw and cradle combination; and ii. corresponding to the dimensions of said article, so that said screw channel and said shelf encase a portion of said article: A. A channel on the external surface of said screw, said channel being of a predetermined width and depth corresponding to the dimensions of said article; B. A singulation blade mounted within said body near the proximal end of the cradle; and C. A removable shelf mounted to at least one interior side of said cradle, wherein at least a portion of said shelf is positioned: i. near the proximal end of said screw and cradle combination; and ii. corresponding to the dimensions of said article, so that said screw channel and said shelf encase a portion of said article: i. near the proximal end of said screw and cradle combination; and ii. corresponding to the dimensions of said article, so that said screw channel and said shelf encase a portion of said article:
