Fluid delivery apparatus

A fluid dispensing oral care implement comprising:

• a head and a handle;
• an outlet located on the head;
• a reservoir located in the handle and having at least one fluid disposed therein;
• and
• a capillary channel in fluid coupling with the at least one fluid in the reservoir and with the outlet to carry the fluid from the reservoir to the outlet for dispensing into a user's mouth, the capillary channel comprising a plurality of concentric members each having different fluid release characteristics;
• a storage cap removably attachable to the head of the oral care implement, the storage cap including a sealing socket configured to substantially conform to the shape of the outlet and an open bottom, wherein when the storage cap is attached to the oral care implement head, the sealing socket is operative to at least partially seal the outlet to minimize evaporative loss of the fluid and a plurality of tooth cleaning elements protrude through the open bottom of the storage cap.

A fluid delivery apparatus comprising:

• a housing defining a reservoir;
• at least one fluid stored in the reservoir;
• a capillary channel in fluid coupling with the at least one fluid and an outlet, the capillary channel comprising a first flow section and a second flow section that are in fluid communication with one another, the first flow section is adjacent to the reservoir and the second flow section is adjacent to the outlet;
• and
• wherein the first flow section has a first fluid flow rate and the second flow section has a second fluid flow rate, the second fluid flow rate being greater than the first fluid flow rate;
• a valve disposed in the housing and in communication with a vent opening disposed in the housing, the valve being operative to introduce external air into the reservoir via the vent opening;
• and
• an end cap disposed on a proximal end of the housing, the valve being seated in the end cap, wherein the end cap is a two-piece component including a handle plug that closes off the proximal end of the housing and a valve plug secured to the handle plug;
• and
• wherein the valve is retained in the end cap by being trapped between the valve plug and the handle plug.
