  • Patent number: 6481337
    Abstract: A controlling mechanism of beverage infusion container. The container includes a partitioning board transversely disposed therein to divide the interior of the container into a first division and a second division. Each division has an opening provided with a cover. The partitioning board is formed with a central draining hole communicating the first division with the second division. The blocking/unblocking of the draining hole is controlled by a controlling mechanism. The controlling mechanism includes a controlling member passed through the circumferential wall of the container. One end of the controlling member extends out of the circumferential wall and is provided with a controlling section. The other end of the controlling member is linked with a valve body positioned at the draining hole of the partitioning board. The valve body is controllable by the controlling section on outer side of the container to block or unblock the draining hole.

  • Patent number: 6477942
    Abstract: A beverage infusion container including a partitioning board transversely disposed in the container to divide the interior of the container into a first division and a second division each having an opening. The partitioning board is formed with a central draining hole. The blocking/unblocking of the draining hole is controlled by a controlling mechanism. A mesh rack is disposed on one side of the partitioning board in the first division. A communicating tube is formed on the partitioning board adjacent to the circumferential wall of the container for communicating the first division with the second division. The mesh rack is formed with a ventilating tube corresponding to the draining hole of the partitioning board. The ventilating tube extends toward the opening of the first division. The communicating tube and the ventilating tube serve as two air flow ways for convection of the air between the first and second divisions.
