  • Patent number: 5439135
    Abstract: A golf tee dispensing device capable of individually releasing one of a number of standard sized golf tees from a plurality of tees stored and retained within the dispensing device. The device includes a tube for the ordered retention of the golf tees and a means for forcing the golf tees upward to an open end of the tube for release. The dispensing device incorporates a pivoting mechanism on the open end of the dispensing tube that is structured so as to singularly release a golf tee from the dispensing device and simultaneously preventing the release of a subsequent golf tee next in line within the tube. A spring within the tube forces the golf tees up through the dispensing tube and appropriately positioned stop tabs on the dispensing mechanism prevent and control the release of the golf tees one at a time from the device.
