A sealing bag comprising:

• a bag body;
• and
• a sealing system comprising:

• and
• a covering assembly comprising:
• a covering component comprising:
• a first covering portion detachably installed on the elastomeric protruding component in a sliding manner, the first covering portion comprising at least one first interlocking portion;
• and
• a second covering portion pivotally connected to the first covering portion, the second covering portion comprising at least one second interlocking portion for cooperating with the at least one first interlocking portion, the second covering portion driving the first covering portion by a cooperation of the at least one first interlocking portion and the at least one second interlocking portion to squeeze the elastomeric protruding component along a lateral direction different from the protruding direction to seal the slit when the first covering portion is installed on the elastomeric protruding component and the second covering portion pivotally engages with the first covering portion, and the at least one first interlocking portion being at least partially inserted into and abutted against the at least one second interlocking portion for preventing the second covering portion from pivotally disengaging from the first covering portion.
