Abstract: A beverage container assembly includes a thin, silicone membrane that is perforated with multiple pinholes and is mounted on a rigid support plate defining multiple vent holes. The silicone membrane rests against an inside surface of the support plate when the pressure inside the container is equal to or greater than the surrounding environment, and the pinholes remain closed to prevent beverage leakage. When beverage is drawn from the container, the resulting pressure differential causes the membrane to bend inward, which opens the pinholes to allow venting of air into the container. The membrane is formed at the end of an elongated silicone fluid containment member that forms a liner inside a container body.

Abstract: A venting mechanism includes a rigid support member and a thin, elastic membrane that is perforated with multiple pinholes. The support member includes a peripheral flange that is secured to the beverage container body, and a rigid support plate that defines one or more always-open vent holes. A flow control member includes the membrane and a peripheral collar surrounding the membrane that is secured to the container body by the peripheral flange. The membrane includes a thin sheet of a suitable elastomeric material that rests against an inside surface of the support plate when the pressure inside the container is equal to or greater than the surrounding environment. The pinholes are formed in the elastomeric material such that they are closed when the membrane is in the resting state, and open when the membrane is stretched in response to a pressure differential or an applied force.

Abstract: A rider support assembly for a bicycle, motorcycle or other multi-wheeled vehicle that utilizes a harness to suspend the rider from a support frame that is attached to a ball-type mounting structure. The support harness includes straps or a sling that is secured to the rider's torso and/or legs. A base section of the support frame includes a connecting structure (e.g., a socket) that is movably connects to and supported by the mounting structure such that the support frame can be pivoted in any direction by the rider during operation. A flexible spine extends upward along the rider's back and is secured to the rider's upper body by the support harness. An optional mounting structure pivots relative to the vehicle to facilitate a relatively stiff spine that supports the rider when sitting upright or leaning back.
