Abstract
A lubricant delivery system for a dental handpiece, the dental handpiece having an air inlet tube having a predetermined internal shape in the vicinity of an open end portion thereof. The lubricant delivery system comprises a squeezable sealed capsule which includes a main body portion and a necked down portion extending from the main body portion. The necked down portion is smaller than the internal shape of the air inlet tube and is insertable into the open end of the air inlet tube. A passage is formed in the necked down portion extending from the main body portion to a tip end portion of the necked down portion. A lubricant fills at least a part of the squeezable main body portion. When the tip end portion of the necked down portion is opened, the opened necked down portion is inserted into the air inlet tube of the dental handpiece and the main body portion is squeezed to expel lubricant contained therein into the handpiece via the air inlet tube. The capsule may be sealed within a packaging material, and may be packaged with or without an opening member, such as a sterile needle or the like. The air inlet tube may be designed to have an opening member, such as a needle, built therein, for piercing the tip end portion of the necked down portion of the capsule.
