[0025] Returning to Fig. 1, spout body 102 includes a base portion 137 and a spout portion 139. Base portion 137 includes a passageway 140 which houses the faucet assembly of U.S. Patent Application Serial No. 11/700,634, filed January 31, 2007, entitled "FAUCET INCLUDING A MOLDED WATERWAY ASSEMBLY," Attorney Docket DFC-P0052-01, as mentioned above. Further, spout portion 139 of spout body 102 includes a channel 142 which receives a first portion 143 fluid transport component 104. Channel 142 extends from passageway 140 to a location proximate the discharge end of spout body 102.

[0026] As shown in Fig. 3, fluid transport component 104 rests in channel 142 when spout assembly 100 is assembled. Cover 110 is positioned over channel 142 and conceals channel 142 from the view of an outside observer. A lip 146 on cover 110 is positioned in a recess 144 of spout body 102. Recess 144 is provided around a complete outside perimeter of spout body 102.

[0027] Referring to Figs. 4 through 7, holder 106 is shown. Holder 106 includes a lower portion 150 which includes threads 152 on an inner surface of a fluid conduit 154. Threads 152 threadably couple aerator body 114 to assemble aerator device 116 to the remainder of spout assembly 100. An upper portion 156 of holder 106 includes an opening 158 of fluid conduit 154. Opening 158 is sized to receive overmold component 120. In one embodiment, the shape of fluid conduit 154 and opening 158 generally are chosen to match the shape of overmold component 120. By matching the shape of the overmold component 120 and the opening 158 of holder 106 the movement of overmold component 120 relative to holder 106 is generally constrained except for in direction 194.

[0028] Opening 158 includes a generally cylindrical part 160 to receive a cylindrical portion 162 (see Fig. 1) of overmold component 120 and a lower disk shaped portion 164 sized to receive a disk shaped portion 166 of overmold component 120. An outer portion of holder 106 includes a plurality of ribs 170 which provide structural support to holder 106. In one embodiment, the shape of ribs 170 is chosen such that when cover 110 is assembled to spout body 102 an inside surface of cover 110 is positioned generally against a top surface 172 of ribs 170 of holder 106. [0029] As shown in Fig. 6, lower portion 150 of holder 106 has a perimeter

180. Perimeter 180 includes a tab 182 positioned below opening 158 of holder 106. Referring to Fig. 8, an enlarged portion 184 of channel 142 of spout body 102 is sized to correspond with the perimeter 180. A perimeter 186 of enlarged portion 184 of channel 142 is recessed. During assembly lower portion 150 of holder 106 is received in recess 190.

[0030] To assemble the spout assembly 100, overmold component 120 is received in opening 158 of holder 106. The assembly of fluid carrying system 101 and holder 106 are positioned in channel 142 such that a ledge 188 of the lower portion 150 which includes perimeter 180 is received in the recess 190 provided in enlarged portion 184 of channel 142.

[0031] In order to assemble the combination of the assembly of holder 106 and fluid carrying system 101 with spout body 102, the combination is moved downward in a direction 192. Once ledge 188 of holder 106 is positioned in recess 190, overmold component 120 may not be moved in direction 194 due to the interference with a wall 195 of channel 142. Wall 195 blocks the egress of or retains overmold component within holder 106. As such, end portion 108 of fluid carrying system 101 is held in place through the cooperation of holder 106 and spout body 102. In other words, to remove overmold component 120 from holder 106, holder 106 and fluid carrying system 101 must be translated upward in direction 196 until ledge 188 is no longer received in recess 190.

[0032] Once the combination of holder 106 and fluid carrying system 101 is properly positioned in recess 190, cover 110 is assembled to spout body 102. Seal 118 is positioned adjacent to sealing surface 132 of overmold component 120. Aerator device 116 is positioned adjacent to seal 118. Aerator body 114 is threadably received by threads 152 of holder 106. The tightening of aerator body 114 compresses seal 118 and forms a water tight seal between aerator device 116 and sealing surface 132 of overmold component.

[0033] In one embodiment, the fluid carrying system 101 is held in place relative to holder 106 snap features provided on one or both of overmold component 120 and holder 106. In one embodiment, the fluid carrying system 101 is held in place relative to holder 106 by clips.
