Description

FIELD OF THE INVENTION

[0002] The present invention relates generally to golf cups. More particularly, it pertains to a sleeve for a golf cup.

BACKGROUND OF THE INVENTION

[0003] In preparing a golf green, a hole is cored into the ground which receives the golf ball therein. Various cups have been inserted into the ground to preserve the shape of the hold and to hold a flag. One example of a cup inserted into the hole is a plastic cup. The plastic cup has several drawbacks, however. For instance, the plastic cup cracks and/or discolors and must be changed regularly during the golfing season. To see the golf cup, the plastic cup is created in white which allows for clear visibility. However, the white plastic becomes dirty easily and must be changed to provide a fresh appearance for the course. To change the cup, the entire cup is removed from the ground, and generally a new hole must be cored into the ground.

[0004] An alternative to providing a plastic cup with a shorter life, is to provide a metal golf cup. The metal golf cup resists cracking. To provide visibility, the interior of the golf cup is painted white. However, as golf ball strike the interior of the golf cup, the paint chips from the interior surface. This problem is exacerbated as golfers strike the wall of the cup while inserting or removing the flag, or while using a club to remove a ball from the cup. To update the painted interior surface of the metal golf cup, the golf cup is removed from the ground and the interior surface is re-painted, which is labor intensive.

[0005] Accordingly, what is needed is a cost effective manner to refresh the interior surface of a golf cup.

SUMMARY OF THE INVENTION

[0006] A golf cup apparatus includes a golf cup comprising a cylinder which extends from a top surface to a bottom surface. In one embodiment, the golf cup is formed of metal. The golf cup is defined in part by a wall having an interior surface and an exterior surface, where the wall extends from a top surface to a bottom surface. In yet another embodiment is a ridge is formed on the interior surface of the cup to retain a sleeve therein.

[0007] Disposed within the golf cup is a cup sleeve, which has a cylindrical shape and abuts the wall of the golf cup. The sleeve, in one embodiment, extends from top surface of the golf cup to the bottom surface of the golf cup, and can be coupled with the golf cup. In another embodiment, the sleeve extends partially between the top surface and the bottom surface of the golf cup, where, optionally, a top portion of the sleeve is substantially aligned with the top surface of the golf cup.
