Abstract
A baby-feeding nipple and conduit system, comprising a baby-feeding nipple having baby-feeding means on one nipple end for feeding a liquid to a baby and an opposite nipple end and a radially closed conduit having one conduit end for receiving the liquid and an opposite conduit end on the opposite nipple end for supplying the liquid to the nipple.
Claims6
A feeding system for infants, comprising, in combination:
- a flexible nipple having a tip end and a base end, said nipple having a longitudinal axis and a transverse axis, and a transversely extending flange on the base end to prevent swallowing of the nipple by the infant;
- said tip end of the nipple having normally closed slits therein defining one-way check valve means for flow of liquid from the nipple in response to sucking action on the nipple by an infant, and operable to prevent leakage of liquid from the nipple and ingress of air into the nipple when an infant is not sucking on the nipple, whereby said check valve means prevents ingress of air into the nipple when sucking action on the nipple ceases and the elevation of liquid in the container is lower than the elevation of the tip end of the nipple, so that liquid that has been drawn into the conduit and nipple will not drain therefrom, regardless of the position of the container or elevation of liquid therein relative to the elevation of the nipple, enabling an infant to drink from a container that is in any position relative to the infant and insuring that liquid remains in the nipple and conduit to prevent ingestion of air by the infant at times when nursing is stopped and then restarted;
- said base end of the nipple having a reduced diameter internal opening extending longitudinally therethrough for receiving a tubular conduit to supply liquid to the nipple in response to sucking action on the nipple;
- an elongate tubular conduit having a first diameter and having one end removably received in the opening in the base end of the nipple and sealed relative thereto, said conduit having another end adapted to extend into a container of liquid to be supplied through the conduit to the nipple and fed through the nipple to an infant;
- and
- said opening in the base end of the nipple having a larger diameter at an outer end thereof and a smaller diameter at an inner end so that said conduit may be removed and any one of a plurality of conduits having a range of different diameters can be received and sealed in said opening.

An infant feeding device, comprising:
- a flexible nipple adapted to be connected with a source of liquid and held in the mouth of an infant and sucked on to obtain liquid from the source, said nipple having a longitudinal axis extending from a base end to a tip end thereof;
- said nipple having a passage means through the tip end thereof for flow of liquid from the nipple in response to sucking action on the nipple by an infant, when the nipple is connected with a source of liquid;
- and
- said base end having a reduced diameter opening extending longitudinally therethrough from an outer end to an inner end, for attachment of an elongate tubular conduit that is adapted to be received at one end thereof in said opening and adapted to be received at its other end in a container holding said source of liquid, said opening having a predetermined length that tapers from a first diameter at its outer end to a second, smaller diameter at its inner end, whereby the tapered opening is adapted to receive and hold any one of a plurality of conduits of different diameters.
