  • Patent number: 12649612
    Abstract: The present technology discloses a multi-position valve for use with a container. The valve can have a frustoconical structure having apertures thereon, and a concentric flap attached to the frustoconical structure by a hinge, wherein the concentric flap pivots from a first closed position to a second open position. When the concentric flap of the interior valve is in the first closed position, the concentric flap abuts against the frustoconical structure and blocks fluid flow through the apertures. When the concentric flap of the interior valve is in the second open position, the concentric flap is pivoted upward at the hinge and away from the frustoconical structure and permits fluid flow through the apertures.
