  • CONTAINER LID WITH INTEGRATED VENT BLOCKING MECHANISM
    Publication number: 20240002114
    Abstract: Embodiments relate to a container lid with vent holes that are blocked for storage but automatically unblocked when a container attached to the container lid is heated. The heating of the container lid causes the pressure to build in the container, which pushes up an upper portion of the container lid. When the upper portion of the container lid is pushed up, the vent holes are unblocked and enable air or vapor to escape through the vent holes. In this way, the container lid may seal the container during storage but enables automatic venting during the heating of the container to prevent buildup of excessive pressure within the container.

  • OPERATING BOTTLE WITH AUTOMATIC ORIENTING HANDLE ASSEMBLY
    Publication number: 20240000666
    Abstract: Embodiments relate to a self-orienting handle assembly that is oriented in a predetermined direction relative to a lid when the lid is screwed onto a container. The handle assembly includes a locking structure that locks onto a counterpart locking structure of the lid as the lid is screwed onto the container. The locking structure may include at least one of a protrusion or a notch, and the counterpart locking structure may have an inverse shape. When the lid is screwed onto the container, the locking structure engages the counterpart locking structure and cause the handle assembly to rotate with the lid. When the lid is screwed onto the container, the locking structure locks onto the counterpart locking structure, and thereby prevents the handle assembly from rotating relative to the lid.
