ABSTRACT:
The present invention is a dental prophylactic polishing paste container-dispenser of unique design, shape and size having an integral ring like holding device as part of the body member to be unfolded or pulled down and used to secure the container-dispenser to the hand of the operator by slipping the ring like device over one of the fingers where it will be held securely by the memory of the plastic ring like device trying to return to its original position. The present invention is designed to allow the prophy cup to be inserted easily and fully able to reach all the internal surfaces of the container-dispenser. The present invention has sloping sides that angle downward and inward at about fourty degrees to meet a smallish bottom surface area that is only slightly larger in diameter than the diameter of the open end of the prophy cup allowing the operator to push any remaining polishing paste down the sloping side of the container-dispenser to the smallish bottom area trapping the polishing paste in the open end of the prophy cup. The present invention will contain and dispense sterile individual portions of polishing paste with an infinite variety as to flavor, color, grit, medicaments and eliminate cross contamination while being easy to manufacture and use, saving materials, time, effort, frustration and money.
