ABSTRACT:
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.
