Abstract: A hermetic container includes a container body, a cap unit, and a control unit. The cap unit is disposed to cover a mouth of the container body, and has an outer cap, a mid cap, and an inner cap having a sealing ring that is movable toward and away from the mid cap and that can be pushed by the mid cap to abut against the mouth when moving to the mid cap. The control unit includes a release button depressably inserted into the cap unit, a sealing button inserted into the cap unit around the release button, and a lever unit connected to the inner cap to interact with the sealing button. The sealing button is movable relative to the release button to switch between a sealing position and a non-sealing position.

Abstract: An apparatus for controlling supply of liquid contained in a container includes an elongate rail frame mounted uprightly on a base and formed with an upright guide slot. A controller is mounted on the rail frame, includes an upper inlet portion engaging fittingly an opening of the container so as to allow flow of the liquid from the container thereinto, and is operable so as to discharge the liquid from a lower outlet portion. A biasing member biases an operating rod to move downwardly relative to the base so as to clamp the container between an abutting rod portion of the operating rod and the controller. An engaging block is formed on the operating rod and is movable within the guide slot to engage a stop block disposed fixedly on the rail frame.
