Patent ID: 7833014

Claim:
An application device comprising: a housing; a rotatable shaft having a first end for attachment to a drive means and a second end attached to a flexible application material chamber; a corrugated member attached at a first end to an applicator retaining means and a second end to a disk member, said applicator retaining means including a channel therethrough and configured to receive an applicator; and a rod extending from said disk member into said flexible application material chamber, said rod having one or more openings in a surface thereof, said one or more openings accessing an inner channel extending through said rod and disk member, said channel providing a path for material contained within said application material container to exit therefrom wherein the disk member is attached at a first end to said flexible application material chamber and at a second end to said corrugated member; and wherein the device is configured such that rotational energy of the rotatable shaft is transferred to the disk member by the flexible application material chamber only, and when resistance is placed on the disk member, it creates a speed differential between the disk member and the rotatable shaft causing the flexible application material chamber to compensate for the speed differential by collapsing.
