Abstract: A bottle nipple device featuring a generally circular base having a top surface, a side edge, and a bottom surface; and a thumb-shaped nipple extending upwardly from the top surface of the base, the thumb-shaped nipple is generally hollow and has a top end, wherein a slot is disposed in the top end. The base is adapted to be sandwiched between a top end of a standard bottle a standard bottle cap, the standard bottle cap has a center hole that allows the nipple to protrude outwardly away from the bottle, the slot is fluidly connected to the bottom surface of the base allowing liquid to flow through the base and out of the slot.

Abstract: The invention relates to a teat for feeding bottles, including a receiving head, produced from a dimensionally stable material, and a rubber-elastic suction element. An entry channel leads to the bottle interior and channels lead from there to the outer surface of the receiving head. The suction element, in an initial position, elastically and sealingly rests on at least one section of an outer surface of the receiving head. Milk ducts are located in the contact area between the suction element and the receiving head and communicate with the channels of the receiving head which lead towards the outlet channel in the mouthpiece so that, when a vacuum is produced in the mouthpiece, milk can flow from the feeding bottle through the milk ducts to the outlet channel, the suction element being returnable to its initial position and the flow of milk being interrupted when there is no vacuum.
