A baby bottle assembly including a nipple having a substantially flat membrane defining multiple pinholes for controlling the flow of liquid. The nipple is mounted on a cap that screws onto the bottle body. The nipple is formed from a suitable elastomeric material (e.g., soft rubber, thermoplastic elastomer, or silicone) such that the membrane stretches when subjected to a differential pressure. The pinholes are formed by puncturing the membrane while subjecting the membrane to radial tension, and using one or more pins having a substantially circular cross-section and sized such that each pinhole is closed by the surrounding elastomeric material when the pins are removed.

1. A baby bottle assembly comprising:a bottle body defining a storage chamber and a threaded neck;a removable cap mounted on the threaded neck, the cap including a top wall defining an opening; anda nipple mounted on the removable cap and including a substantially flat membrane formed from an elastomeric material,wherein the membrane defines a plurality of pinholes formed such that each pinhole is closed by the elastomeric material surrounding said each pinhole when the membrane is subjected to normal atmospheric conditions, thereby preventing passage of a liquid from the storage chamber through the membrane, and each pinhole is opened when the membrane is subjected to an applied pressure differential that causes the membrane to stretch, thereby facilitating liquid flow from the storage chamber.2. The baby bottle assembly according to claim 1, wherein the membrane has a circular outer perimeter having a diameter of 0.25 to 1.0 inches and a thickness of 0.01 to 0.1 inches, and wherein the plurality of pinholes comprises a number greater than ten.3. The baby bottle assembly according to claim 2, wherein the number of pinholes is greater than thirty.4. The baby bottle assembly according to claim 1, wherein the nipple further comprises:a disk shaped flange;a lower conical wall section extending upward from the flange;a neck region located at an upper end of the lower conical wall section;an upper conical wall section extending upward from the neck region,wherein the substantially flat membrane is formed on an upper portion of the upper conical wall section.5. The baby bottle assembly according to claim 4, wherein the membrane has thickness of 0.01 to 0.1 inches, and wherein the plurality of pinholes comprises a number greater than ten.6. The baby bottle assembly according to claim 5, wherein a thickness of the flange is 0.06 to 0.1 inches, wherein a thickness of the lower conical wall section is 0.04 to 0.08 inches, and wherein a thickness of the upper conical wall section is 0.04 to 0.08 inches.7. The baby bottle assembly according to claim 4, wherein the lower conical wall section defines a first diameter, the neck region defines a second diameter, and the membrane defines a third diameter, wherein the second diameter of the neck region is less than the first diameter of the lower conical wall section and the third diameter of the membrane.8. The baby bottle assembly according to claim 1, wherein the membrane is circular.9. The baby bottle assembly according to claim 1, wherein the membrane is oval.10. The baby bottle assembly according to claim 1, wherein the nipple comprises silicone.11. The baby bottle assembly according to claim 1, wherein the nipple comprises thermoplastic elastomer.12. The baby bottle assembly according to claim 1, wherein the nipple comprises soft rubber.13. A nipple for a baby bottle assembly, the nipple comprising:a wall section defining an interior chamber, the wall section having a first thickness; anda disk-shaped membrane connected to the wall section such that the membrane covers a portion of the interior chamber,wherein the membrane has a second thickness that is smaller than the first thickness of the wall section, andwherein the membrane defines a plurality of pinholes formed such that each pinhole is closed by elastomeric material surrounding said each pinhole when the membrane is subjected to normal atmospheric conditions, thereby preventing passage of a liquid through the membrane, and each pinhole is opened when the membrane is subjected to an applied pressure differential that causes the membrane to stretch, thereby facilitating liquid flow through the membrane.14. The nipple according to claim 13, wherein the membrane has a circular outer perimeter having a diameter of 0.25 to 1.0 inches and a thickness of 0.01 to 0.1 inches, and wherein the plurality of pinholes comprises a number greater than ten.15. The nipple according to claim 14, wherein the number of pinholes is greater than thirty.16. The nipple according to claim 13, wherein the membrane is circular.17. The nipple according to claim 13, wherein the membrane is oval.18. The nipple according to claim 13, wherein the nipple comprises at least one of silicone, thermoplastic elastomer, and soft rubber.
