Title: SEALED BAG AND METHOD FOR USING SAME
Abstract:
A sealed bag, comprising: a bag body (11) as well as a first zipper (12), a second zipper (13) and a deflation device (14), which are provided on the bag body (11); the bag body (11) is provided with a receiving space (111) and an opening (11a), which connects the receiving space (111) to the outside; the first zipper (12) is used for closing the opening (11a), and the second zipper (13) is used for dividing the receiving space (111) into a first space (111a) and a second space (111b), the first space (111a) being located between the first zipper (12) and the second zipper (13); the deflation device (14) is disposed between the first zipper (12) and the second zipper (13) and is used for guiding gas in the first space (111a) to the outside, the deflation device (14) causes the first space (111a) to approach a vacuum such that an external force which the atmosphere applies on the bag body (11) is greater than an outward expanding force which is applied on the bag body (11) due to gas expansion in the second space (111b), the second zipper (13) consistently remaining closed.
