Detailed reference will now be made to a first potential embodiment of the disclosure, which is illustrated in FIGS. 1 through 5.

The liquid-dispensing pacifier 100 (hereinafter invention) comprises a nipple 200, a fluid dispenser 300, and a guard 270. The invention 100 is a toy adapted for a baby to suck on. The invention 100 may deliver a fluid 900 from the fluid dispenser 300 via the nipple 200. As non-limiting examples, the fluid 900 may be breast milk or formula.

The nipple 200 may be a cylindrical feature of the invention 100 that is adapted to resemble a female human teat. The nipple 200 may be made from a flexible material. As non-limiting examples, the nipple 200 may be rubber, plastic, or silicone. The nipple 200 may comprise a bulbous end 205. The bulbous end 205 may be adapted to make it easier for the baby to keep the nipple 200 in their mouth. The interior of the nipple 200 may be hollow, comprising a chamber 210. The bulbous end 205 may comprise one or more fluid apertures 215. The one or more fluid apertures 215 may allow the fluid 900 located within the chamber 210 to flow out of the nipple 200.

The fluid dispenser 300 may hold the fluid 900 and may pass the fluid 900 to the nipple 200 in a controlled manner. As non-limiting examples, passing the fluid 900 to the nipple 200 in a controlled manner may indicate that the fluid 900 is passed to the nipple 200 when demanded by the baby or that the fluid 900 is passed to the nipple 200 under control of an adult. The fluid 900 may pass from the fluid dispenser 300 to the nipple 200 via one or more apertures, valves, or tubes.

The guard 270 may be a curved shield surrounding the nipple 200. The guard 270 may prevent the invention 100 from accidently being swallowed.

In some embodiments, the nipple 200 may comprise a pressure sensor 230, a dispensing valve 234, and a link 232. The pressure sensor 230 may be an area of the nipple 200 that is adapted to move when the baby sucks on the nipple 200. As a non-limiting example, the pressure sensor 230 may be a disk in contact with the wall of the nipple 200. The dispensing valve 234 may control the flow of the fluid 900 from the fluid dispenser 300 into the chamber 210 located within the nipple 200. The link 232 may couple at one end to the pressure sensor 230 and at the other end to the dispensing valve 234 such that mechanical pressure applied to the pressure sensor 230 when the nipple 200 is sucked may move the link 232 and may cause the dispensing valve 234 to open and start the flow of the fluid 900 from the fluid dispenser 300 to the chamber 210. The link 232 may return to its original position when pressure is removed and may allow the dispensing valve 234 to close and stop the flow of the fluid 900 from the fluid dispenser 300 to the chamber 210.

In some embodiments, the nipple 200 may comprise a feeding tube 240. The feeding tube 240 may be a tube leading from the fluid dispenser 300 to the chamber 210. The feeding tube 240 may limit the rate at which the fluid 900 flows from the fluid dispenser 300 into the chamber 210. As a non-limiting example, the feeding tube 240 may be spiral tubing with a diameter that limits the fluid flow through the tubing to less than a predefined flow rate.

In some embodiments, the fluid dispenser 300 may comprise a reservoir 310, a neck 320, and a cap 325. The reservoir 310 may be a hemispherical, watertight container adjacent to the nipple 200. The reservoir 310 may hold the fluid 900 before the fluid 900 is introduced into the nipple 200 for consumption. The neck 320 may be a cylindrical opening to the reservoir 310 through which the fluid 900 may be added to or removed from the reservoir 310. The outside of the neck 320 may be threaded for coupling to the cap 325. The cap 325 may be a removable covering for the neck 320. The inside of the cap 325 may be threaded with a thread that complements the thread on the neck 320 such that the cap 325 may be installed and removed by twisting one direction of the other. When installed, the cap 325 may form a watertight seal with the neck 320 and may prevent the fluid 900 for exiting the reservoir 310.

In some embodiments, the reservoir 310 may be made from a resilient material that flexes when pressed. Applying external pressure to the reservoir 310 may increase the internal pressure of the reservoir 310 and may force the fluid 900 from the reservoir 310 into the nipple 200.

In some embodiments, the fluid dispenser 300 may comprise a syringe 350. The syringe 350 may be a manually-operated reciprocating pump comprising a barrel 360 and a plunger 365. The barrel 360 may be a hollow cylinder that forms an outside wall of the syringe 350. One end of the barrel 360 may couple to the nipple 200 and/or the guard 270. The other end of the barrel 360 may be open to allow the plunger 365 to be inserted into the barrel 360. In some embodiments, the barrel 360 may comprise indicia 380 to indicate the volume of fluid contained within the syringe 350. One end of the plunger 365 may comprise a seal 370. The other end of the plunger 365 may comprise a handle 375. The seal 370 may be a movable, watertight contact between the plunger 365 and the inside of the barrel 360. As a non-limiting example, the seal 370 may comprise an O-ring that couples to the end of the plunger 365 and has an outside diameter that matches the inside diameter of the barrel 360. The handle 375 may be a grasping point for operating the syringe 350. The syringe 350 may draw the fluid 900 into the barrel 360 as the plunger 365 is withdrawn from the barrel 360 and may expel the fluid 900 from the barrel 360 as the plunger 365 is pushed into the barrel 360.

In some embodiments, the syringe 350 may be detachable from the rest of the invention 100. Detaching the syringe 350 may facilitate cleaning the syringe 350 and reloading the syringe 350. As a non-limiting example, the end of the barrel 360 opposite the plunger 365 may screw into a threaded aperture on the nipple 200.

In use, the fluid dispenser 300 may be filled with the fluid 900, non-limiting examples of which include the breast milk and the formula. The fluid dispenser 300 may be filled either by removing the cap 325, pouring the fluid 900 into the reservoir 310, and replacing the cap 325 or by introducing the fluid 900 into the barrel 360 of the syringe 350. The nipple 200 may be placed into the mount of the baby. As the baby suckles, small amounts of the fluid 900 may be released into the nipple 200—either due to the sucking or due to the adult gently and occasionally pressing the plunger 365. The fluid 900 released into the nipple 200 may be sucked from the nipple 200 via the one or more fluid apertures 215 and may be consumed by the baby. The fluid 900 consumed by the baby may supplement a normal feeding schedule and may help pacify the baby.
