Airtight device

An airtight device, comprising:

• a container;
• and
• an airtight cover disposed on the container, wherein the airtight cover comprises:
• a fixing bracket having two through holes and a plurality of guiding slots, wherein the two through holes communicate with an interior space of the container, each of the guiding slots comprises a relatively wide opening and a relatively narrow opening, the relatively narrow opening has a first top surface and the relatively wide opening has a second top surface higher than the first top surface;
• two doors configured to cover the two through holes respectively;
• and
• a plurality of pressuring handles pivoted to the two doors respectively, each of the pressuring handles having a first section, a second section, and a rotation pivot disposed between the first and second sections, wherein the first section and the second section are configured to rotate relative to each other, and wherein the second section is configured to receive a force for driving the first section to move from below the second top surface to below the first top surface such that the rotation pivot pressures a corresponding one of the two doors.

An airtight device, comprising:

• a container;
• and
• an airtight cover disposed on the container, wherein the airtight cover comprises:
• a fixing bracket having at least one through hole, at least one guiding slot, and a guiding rail, wherein the through hole communicates with an interior space of the container, the guiding rail is above the through hole and has a first portion which has a height gradually increasing relative to the through hole, and the guiding slot comprises a first top surface and a second top surface higher than the first top surface, the guiding slot and the guiding rail are separate and different concave structures on a sidewall of the fixing bracket;
• at least one door configured to cover the through hole, wherein the door has a protruding portion inserted into the guiding rail, and wherein the door is configured to move toward a lowest end of the first portion such that the door is at a closed height;
• and
• at least one pressuring handle pivoted to the door, the pressuring handle having a first section, a second section, and a rotation pivot disposed between the first and second sections, wherein the first section and the second section are configured to rotate relative to each other, and wherein the second section is configured to receive a force for driving the first section to move from below the second top surface to below the first top surface such that the rotation pivot pressures the door.
