A flow control valve assembly is mounted to the nipple flange and extends inwardly from an inner surface
A nipple assembly is removably attachable to a baby bottle via a retainer ring and comprises a nipple having a flow aperture through one end, and a nipple flange structured to support the nipple. A flow control valve assembly is mounted to the nipple flange and extends inwardly from an inner surface of the nipple flange, the flow control valve assembly is structured to allow pressures to equilibrate between the inside and outside of the baby bottle, without allowing fluid to leak therethrough. A training cup spout assembly is removably attachable to a cup and comprises a spout having a spout channel extending therethrough. The spout channel has a dual valve assembly mounted therein to permit flow for drinking, as well as to prevent leakage of fluid from the cup. A flow control valve assembly may be mounted to the training cup spout assembly to permit pressure equilibration.

1. A nipple assembly structured to be removably attached to a baby bottle via a retainer ring, said nipple assembly comprising: a nipple having a flow aperture disposed through one end,a nipple flange supporting said nipple, wherein said nipple extends outwardly from an outer surface of said nipple
1. A nipple assembly structured to be removably attached to a baby bottle via a retainer ring, said nipple assembly comprising: a nipple having a flow aperture disposed through one end,a nipple flange supporting said nipple, wherein said nipple extends outwardly from an outer surface of said nipple flange,a flow control valve assembly mounted to said nipple flange, wherein said flow control valve assembly extends inwardly from an inner surface of said nipple flange, said flow control valve assembly comprising: a port disposed through a portion of said nipple flange,an elongated channel substantially surrounded by a channel wall, said elongated channel having an open proximal end and an oppositely disposed distal end,said open proximal end of said elongated channel disposed in fluid communication with said port,said channel wall comprising a fixed wall attached to said nipple flange along and around a periphery of said port,said channel wall further comprising an expandable wall attached along and around a periphery of said fixed wall,a channel header attached to said expandable wall, said channel header sealing said distal end of said elongated channel,a plurality of unidirectional valve members mounted to said expandable wall, each of said plurality of unidirectional valve members comprise complementary substantially planar sealing surfaces disposable between a closed orientation and an open orientation, wherein said closed orientation is at least partially defined by corresponding ones of said complementary substantially planar sealing surfaces abutting one another and said open orientation is at least partially defined by corresponding ones of said complementary substantially planar sealing surfaces positioned a spaced distance apart from one another forming a pressure equilibration flow path therebetween permitting air to flow in from said elongated channel to equilibrate pressures on opposite sides of said channel wall, andsaid corresponding ones of said complementary substantially planar sealing surfaces maintained substantially parallel relative to one another between said closed orientation and said open orientation. 2. The nipple assembly as recited in claim 1 wherein said elongated channel comprises an elliptical cross-section having a major axis and a minor axis. 3. The nipple assembly as recited in claim 2 wherein one of said plurality of unidirectional valve members is mounted at one vertex of said major axis of said elongated channel and another of said plurality of unidirectional valve members is mounted at an opposite vertex of said major axis of said elongated channel. 4. The nipple assembly as recited in claim 3 wherein said fixed wall comprises a mean thickness in a range of about 1.2 millimeters to about 1.8 millimeters. 5. The nipple assembly as recited in claim 4 wherein said expandable wall comprises a mean thickness in a range of about 0.4 millimeters to about 0.8 millimeters. 6. The nipple assembly as recited in claim 5 wherein said expandable wall comprises a resilient construction to permit corresponding ones of said complementary substantially planar sealing surfaces to be positioned said spaced distance apart from one another to form said pressure equilibration flow path therebetween, and to permit corresponding ones of said complementary substantially planar sealing surfaces to return to abutting one another in said closed orientation. 7. A training cup spout assembly removably attachable to a drinking cup, said spout assembly comprising: a spout having a spout channel extending therethough, said spout channel surrounded by a channel wall and having an open proximal end and an oppositely disposed open distal end,said spout attached to and extending outwardly from an outer surface of a spout flange,said spout comprising a dual valve assembly mounted in said spout channel, said dual valve assembly comprising: a diaphragm valve member mounted in said spout channel between said oppositely disposed open ends,said diaphragm valve member comprising a pair of diaphragm surfaces, each of said diaphragm surfaces attached in a sealing engagement along oppositely disposed internal surfaces of said spout channel, said diaphragm surfaces defining a diaphragm aperture therebetween,a dome valve member mounted to said diaphragm valve member, said dome valve member disposed in an overlying relation to said diaphragm aperture,said dome valve member comprising complementary sealing surfaces disposable between a closed orientation and an open orientation, wherein said closed orientation is at least partially defined by said complementary sealing surfaces abutting one another and said open orientation is at least partially defined by said complementary sealing surfaces positioned a spaced distance apart from one another to form a fluid flow path from said open distal end of said spout channel, between said complementary sealing surfaces of said dome valve member, through said diaphragm aperture, and to said open proximal end of said spout channel, anda flow control valve assembly mounted to said spout flange comprising a flow control valve member disposable between a closed orientation and an open orientation, wherein said open orientation permits pressures to equilibrate on opposite sides of said flow control valve assembly. 8. The spout assembly as recited in claim 7 wherein each of said diaphragm surfaces is attached at an angle relative to said internal surfaces of said spout channel wall. 9. The spout assembly as recited in claim 8 wherein said angle in a range of about 140 degrees to 160 degrees. 10. The spout assembly as recited in claim 9 wherein said diaphragm surfaces comprise a mean thickness and said dome valve member comprises a mean thickness. 11. The spout assembly as recited in claim 10 wherein said mean thickness of said diaphragm surfaces is about one half said mean thickness of said dome valve member. 12. The spout assembly as recited in claim 10 wherein said mean thickness of said diaphragm surfaces is in a range of about 0.6 millimeters to 0.8 millimeters. 13. The spout assembly as recited in claim 12 wherein said mean thickness of said dome valve member is in a range of about 1.2 millimeters to 1.6 millimeters.
