Abstract: A vented closure is provided for use on a liquid container. The body of the closure (16) includes a dispensing port and a vent (28) extending therethrough with the vent adjacent the dispensing port (26). The tube (32) extends through the dispensing port (26) and has a flange (38) extending laterally therefrom, engaging the outer surface (20) of the closure body. A flexible seal (40) member is positioned on the tube (32), spaced from the inner surface (28) and having a frusto-conical shape where the inner end (40a) of the member is formed at the tube (32). The outer end (40b) is spaced away from the tube (32) and engages the inner surface (28) of the closure body (16), forming a hollow area (41) between the member (40) and the tube (32). The flexible seal member (40) is movable radially away from the tube (32) and away from the inner surface (28) to the inflow of air through the vent and over the flexible seal member (40).

Abstract: A hearing instrument may include an enclosure adapted for behind-the-ear placement that houses a microphone for converting an acoustical input signal to an electrical signal and a sound processing circuit for processing the electrical signal; an earpiece adapted for in-the-canal placement that includes a receiver for converting the processed electrical signal to an acoustical output signal; a replaceable battery housed in the enclosure for powering the microphone, sound processing circuit and receiver; and an electrical cable extending from the enclosure that electrically couples the processed electrical signal from the sound processing circuit to the receiver. The enclosure includes a top portion and a bottom portion. The top portion and the bottom portion pivot about a hinge point at one end of the enclosure to open and closed positions. In the open position, the battery is accessible for replacement.
