Patent number: 7946848Abstract: A dispenser made of a pliable material having a slit therein for dispensing primarily low viscosity materials. A block made of pliable foam contains a low viscosity material within a slit. Dental instruments or dental material applicators having an applicating end are inserted into the slit of the block, coating the applicator end with the low viscosity material. The resilient nature of the block material also helps to keep the dental instrument clean by wiping the instrument against the interior sides of the pocket formed by the slit. The present invention is particularly well suited for dispensing a lubricating material, such as a resin, on dental instruments used in working, shaping, or contouring a relatively viscous composite restorative material on a patient's tooth.Type: GrantFiled: October 5, 2005Date of Patent: May 24, 2011Assignee: Centrix, Inc.Inventor: John J.
