Patent number: 5289943Abstract: A gravity feed dispensing holder which is adapted to receive and dispense cans directly from the open end of a multi-can carton. The open end of the multi-can carton fits into the holder which supports the carton on its side so the long axes of the cans are horizontal and at right angles to the direction of movement of the cans toward the open end of the carton. The holder tilts the carton towards its open end to cause gravity flow of the cans toward the open end of the carton into an outer extension of the holder. The holder substantially surrounds the bottom side, the open end and the lower front portion of the top and bottom of the carton. The outer extension of the holder has an upwardly facing opening from which the cans are successively removed. Gravity feed of the cans confined in the carton causes them to roll towards the opening for dispensing.Type: GrantFiled: April 20, 1992Date of Patent: March 1, 1994Inventor: Philip M. Powell
