Specifically, the fixing bracket 210 can be made of metal, alloy, or polymer which has higher rigidity. For instance, the fixing bracket 210 is made of steel, aluminum metal, aluminum alloy, or plastic. In addition, the guiding slots 213 of the fixing bracket 210 can be manufactured by a machining process or a laser cutting process, but the present disclosure is not limited in this respect. The doors 230 are in shapes corresponding to shapes of the through holes 211 of the fixing bracket 210, and the doors 230 can be rectangular or square. The through holes 211 can also be rectangular or square, and the doors 230 are slightly greater than the through holes 211. Therefore, when the doors 230 respectively cover the through holes 211, the doors 230 can respectively entirely block the through holes 211 from a top view. In addition, each of the doors 230 includes the periphery frame and a transparent sheet surrounded by the periphery frame such that the users can see the interior space of the container 100 through the doors 230. The periphery frame can include metal, alloy, or polymer, such as steel, aluminum metal, aluminum alloy, and plastic which has higher rigidity. The transparent sheet can include transparent glass or transparent polymer, but the present disclosure is not limited in this respect.
In some embodiments of the present disclosure, the fixing bracket 210 further includes two sidewalls 214 and two guiding rails 215, and the two sidewalls 214 which are respectively located at two corresponding sides of the through holes 211 extend on a top surface of the fixing bracket 210. The guiding slots 213 and the two guiding rails 215 are at least located at a side where the two sidewalls 214 face the through holes 211, and the doors 230 are located between the two sidewalls 214 and slidably connected between the two guiding rails 215. In some other embodiments of the present disclosure, each of the guiding slots 213 and the two guiding rails 215 extends from a front surfaces of the corresponding sidewall 214 which faces the through holes 211 to a rear surfaces of the corresponding sidewall 214 such that each of the pressuring handles 250 can smoothly rotate by receiving a force after the first section 251 is inserted into the corresponding guiding slot 213. The present disclosure is not limited in this respect.

In some embodiments of the present disclosure, each of doors 230 includes handles 234, and the handles 234 and the protruding portions 231 are respectively located at two corresponding sides of each door 230, the user can lift and move the doors 230 by the handles 234. When the users move the doors 230 or rotate the doors 230 relative to the protruding portions 231, the guiding rails 215 respectively support the protruding portions 231. Therefore, the protruding portions 231 are pivot points of the doors 230 as moving or rotating the doors 230, so as to save the users' strength.
Specifically, the guiding rails 215 are inverted U-shaped, and the guiding rails 215 are higher than and entirely above the top surface of the fixing bracket 210 and the through holes 211. Each of guiding rails 215 has two first portions 215a, and each of the two first portions 215a has a height which is relative to the top surface of the fixing bracket 210 or the through holes 211 gradually increasing toward a center of each guiding rail 215. Therefore, the first portions 215a are higher than the fixing bracket 210 and inclined relative to the top surface the fixing bracket 210. In addition, each guiding rail 215 has a second portion 215b, and the second portion 215b has a consistent height relative to the through holes 211 or the top surface of the fixing bracket 210, in which the second portion 215b which communicates with higher ends of the two first portions 215a is located between the two first portions 215a. Therefore, each of first portions 215a has the height relative to the top surface of the fixing bracket 210 gradually increasing toward the second portion 215b. In addition, each door 230 can move inclinedly along the corresponding first portion 215a, in which each door 230 can move vertically and horizontally along the corresponding first portion 215a. Each door 230 can also horizontally move along the second portion 215b of the corresponding guiding rail 215, and each door 230 can be pushed to move between the first portions 215a and the second portion 215b.
In practical application, the two doors 230 can move toward lowest end of the corresponding first portions 215a such that the airtight cover 200 is in a closed state. One of the two doors 230 can move away from a lowest end of the corresponding first portions 215a such that the airtight cover 200 is in an open state. Each door 230 can move toward the corresponding through hole 211 to cover the corresponding through hole 211. Each door 230 can move away from the corresponding through holes 211 along the corresponding first portions 215a to leave the corresponding through hole 211. Referring to
In some embodiments of the present disclosure, the guiding slots 213 are lower than the second portions 215b of the guiding rails 215, and the guiding slots 213 are between the two first portions 215a. Therefore, when the doors 230 are located at the first portions 215a and at the closed height to cover the through holes 211, the pressuring handles 250 push against the guiding slots 213 to pressure the doors 230, so as to prevent the pressuring handles 250 from affecting the doors 230 as rotating. The present disclosure is not limited in this respect.
In some embodiments of the present disclosure, each door 230 includes two sliding rails 235 which extend parallel to each other and two sliding blocks 237, and the two sliding rails 235 are located on a top surface of the corresponding door 230, the sliding blocks 237 are located at a bottom surface of the corresponding door 230. Moreover, the two sliding rails 235 extend from an edge of the corresponding door 230 to another edge of the corresponding door 230, and thus the two sliding rails 235 can fix the door 230 and increase the mechanical strength of the door 230. For instance, the two sliding rails 235 extend across two opposite sides of the corresponding door 230. Referring to

In other embodiments of the present disclosure, the airtight cover 200 does not include the sidewalls 214 and the guiding rails 215, and the doors 230 are detachably fixed to the fixing bracket 210. Therefore, the users can put the doors 230 which are separated from the fixing bracket 210 on the fixing bracket 210, and then the users can fix the doors 230 to the fixing bracket 210 via the fixing lock 280. The users can use the pressuring handles 250 to pressure the doors 230 such that the airtight cover 200 is in the airtight state. Moreover, after the users release the airtight state of the airtight cover 200 by using pressuring handles 250, the users can further unlock the fixing lock 280, and the doors 230 are in a detachable state relative to the fixing bracket 210 such that the users can easily move the doors 230 away from the fixing bracket 210.
