Oral care implement having fluid delivery system

摘要

An oral care implement has a head portion with tooth cleaning elements on one surface thereof and a reservoir containing at least one active agent. A capillary channel extends through at least a portion of the oral care implement to deliver active agent(s) to one or more outlets. In one aspect, a vibration-producing device is provided to vibrate at least a portion of the implement to enhance the function of tooth cleaning elements and the delivery of the active agent through capillary action. A variety of active agents can be administered for therapeutic, hygienic, and/or other benefits, such as fresh breath, tooth whitening, or producing sensations of heat, cool, or tingling.
