罐体由中罐3和底罐1组成，中罐3，相对底罐1的容积而言可以储藏更多的食物，并灵活的控制罐内多余空间与其他配件组合使用，达到排除多余空气的目的，底罐1主要用于储藏密封的食物口部位置与滑动密封圈2紧密配套起到密封的功能,与中罐3设置的滑动密封圈2配套使用，在东西不多的时候内层可以压入外层排出多余空气，减少体积与空间占用，独特的密封罐盖4配合密封环10的设计顺利的保证排气，同时最大限度的自动排出密封罐里面多余的空气，在需要装更多物品的时候又可以伸长变成上下两个密封罐增加容量，同样的，密封罐内存放的有些物品自身会产生气体，这会导致密封罐内的气体变多，这时产生的气体就会顶开密封环10，气体依次通过下排气孔9、间隙、通孔B23，上排气孔6导出，气体通过通孔B23时，会产生一定的声音，提示使用者罐内的气体正在排放，由于还在密封环10上设置了弹性复位件11，所以在排气完成后，会将密封环10自动推回到原来的位置，密封下排气孔9，从而密封罐体。The tank body is composed of a middle tank 3 and a bottom tank 1. The medium tank 3 can store more foods relative to the volume of the bottom tank 1, and flexibly control the excess space in the tank to be combined with other accessories to eliminate excess air. The purpose is that the bottom tank 1 is mainly used for storing and sealing the mouth of the food and is closely matched with the sliding sealing ring 2 to function as a sealing, and is matched with the sliding sealing ring 2 provided in the middle tank 3, and the inner layer can be used when there are not many things. Pressing the outer layer to discharge excess air reduces the volume and space occupation. The unique sealed can lid 4 cooperates with the design of the sealing ring 10 to ensure the exhaust gas smoothly, and at the same time automatically discharges the excess air inside the sealed tank, and needs to install more When the item is extended, it can be extended into two upper and lower sealed cans to increase the capacity. Similarly, some items stored in the sealed can itself generate gas, which will cause more gas in the sealed can, and the gas generated will be generated. Opening the seal ring 10, the gas passes through the lower exhaust hole 9, the gap, the through hole B23, and the upper exhaust hole 6 in sequence. When the gas passes through the through hole B23, a certain sound is generated, prompting the user to Since the gas is being discharged, since the elastic returning member 11 is also provided on the seal ring 10, after the exhausting is completed, the seal ring 10 is automatically pushed back to the original position, and the lower vent hole 9 is sealed, thereby sealing the can body.
