Abstract
Abstract An improved dauber having a applicator pad which may have its central portion radially tensioned or which pad may have a predetermined degree of looseness. The improved dauber comprises a discrete retaining ring which is forced into a U-shape channel of the dauber along with the peripheral portion of the pad so that the peripheral portion of the pad is secured intermediate at least a portion of the retaining ring and an adjacent portion of the wall of the U-shape channel. Also, the peripheral portion of the pad may be partially wrapped about the retaining ring to provide more resistance to being loosened by rubbing. The retaining ring may comprise shaped portions such as serrations, teeth, hooks, or points which engage the peripheral portion of the pad during assembly of the dauber so that the central portion of the pad may become radially tensioned. The retaining ring and the peripheral portion of the pad are locked in the U-shape channel by substantially closing the channel.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
220 words
A method of assembling the applicator portion of a dauber comprising a porous pad, a discrete, substantially rigid and unsplit retaining ring, and a body having an annular inner rim having a right-cylindrical-shape outwardly facing surface, an annular outer rim having a right-cylindrical-shape inwardly facing surface and an upwardly open U-shape annular channel intermediate said right-cylindrical-shape surfaces, said rims and said channel being so sized with respect to said pad and said ring that the peripheral portion of said pad and said retaining ring have an interference fit in said channel when the peripheral portion of said pad is partially wrapped about said retaining ring and said retaining ring is disposed in said channel, said pad being retained in said applicator when assembled by the method which comprises the steps of: positioning said pad with respect to said channel so that the peripheral portion of said pad is disposed superjacent said channel; placing said retaining ring superjacent said peripheral portion of said pad so that said peripheral portion of said pad is intermediate said ring and said channel; and telescoping said retaining ring into said channel so that said peripheral portion of said pad is concurrently pulled into said channel and said peripheral portion of said pad becomes substantially wrapped into an upwardly open U-shape annulus about said retaining ring.
Claim 2
Independent Claim
220 words
A method of assembling the applicator portion of a dauber comprising a porous pad, a discrete, substantially rigid and unsplit retaining ring, and a body having an annular inner rim having a right-cylindrical-shape outwardly facing surface, an annular outer rim having a right-cylindrical-shape inwardly facing surface and an upwardly open U-shape annular channel intermediate said right-cylindrical-shape surfaces, said rims and said channel being so sized with respect to said pad and said ring that the peripheral portion of said pad and said retaining ring have an interference fit in said channel when the peripheral portion of said pad is partially wrapped about said retaining ring and said retaining ring is disposed in said channel, said pad being retained in said applicator when assembled by the method which comprises the steps of: positioning said pad with respect to said channel so that the peripheral portion of said pad is disposed superjacent said channel; placing said retaining ring superjacent said peripheral portion of said pad so that said peripheral portion of said pad is intermediate said ring and said channel; and telescoping said retaining ring into said channel so that said peripheral portion of said pad is concurrently pulled into said channel and said peripheral portion of said pad becomes substantially wrapped into an upwardly open U-shape annulus about said retaining ring.
Claim 3
Independent Claim
208 words
A method of assembling the applicator portion of a dauber comprising a porous pad, a discrete, substantially rigid and unsplit retaining ring, a body having an inner rim, an outer rim and an upwardly opening U-shape annular channel intermediate said rims, said rims and said channel being so sized with respect to said pad and said ring that said pad will be retained by an interference fit when assembled by the method which comprises the steps of: positioning said pad with respect to said channel so that the peripheral portion of said pad is disposed adjacent said channel; placing said retaining ring adjacent said peripheral portion of said pad so that said peripheral portion of said pad is intermediate said ring and said channel; telescoping said retaining ring into said channel to cause said peripheral portion of said pad to be pulled into said channel and to become wrapped into an upwardly open U-shape annulus about said retaining ring and secured by an interference fit intermediate said retaining ring and the adjacent walls of the U-shape channel; and, locking the retaining ring and the peripheral portion of the porous pad within the channel by displacing at least one said rim towards the other to substantially close said channel.
Claim 4
Independent Claim
208 words
A method of assembling the applicator portion of a dauber comprising a porous pad, a discrete, substantially rigid and unsplit retaining ring, a body having an inner rim, an outer rim and an upwardly opening U-shape annular channel intermediate said rims, said rims and said channel being so sized with respect to said pad and said ring that said pad will be retained by an interference fit when assembled by the method which comprises the steps of: positioning said pad with respect to said channel so that the peripheral portion of said pad is disposed adjacent said channel; placing said retaining ring adjacent said peripheral portion of said pad so that said peripheral portion of said pad is intermediate said ring and said channel; telescoping said retaining ring into said channel to cause said peripheral portion of said pad to be pulled into said channel and to become wrapped into an upwardly open U-shape annulus about said retaining ring and secured by an interference fit intermediate said retaining ring and the adjacent walls of the U-shape channel; and, locking the retaining ring and the peripheral portion of the porous pad within the channel by displacing at least one said rim towards the other to substantially close said channel.
Claim 5
Dependent Claim
104 words
An improved dauber having a body and a porous pad wherein the peripheral portion of the pad is swaged into an upwardly open U-shape annular channel, said improvement comprising the addition of a discrete, substantially rigid and unsplit retaining ring disposed in said channel and having said peripheral portion of said pad formed into an upwardly open U-shape annulus about said discrete retaining ring, said pad, retaining ring, and said channel being so relatively sized and configured to provide means for securing said pad sufficiently tightly by an interference fit that loosening of the pad under the action of vigorous rubbing is virtually obviated.
Claim 6
Dependent Claim
104 words
An improved dauber having a body and a porous pad wherein the peripheral portion of the pad is swaged into an upwardly open U-shape annular channel, said improvement comprising the addition of a discrete, substantially rigid and unsplit retaining ring disposed in said channel and having said peripheral portion of said pad formed into an upwardly open U-shape annulus about said discrete retaining ring, said pad, retaining ring, and said channel being so relatively sized and configured to provide means for securing said pad sufficiently tightly by an interference fit that loosening of the pad under the action of vigorous rubbing is virtually obviated.
Claim 7
Dependent Claim
16 words
The improved dauber of claim 3 wherein the porous pad is radially tensioned a predetermined amount.
