Technical Field

[0001] The invention relates to a storage bag and a vacuum compression bag with bag openings capable of being automatically tightened. Background Art

[0002] In the prior art, storage bags with a sealing structure are often used to store different items. When a specific item needs to be taken out from a pile of items in the storage bag, other items are easily dragged out and taken out together. Especially in a weightless state such as a spacecraft, when the bag opening of the storage bag is opened, the items are easily automatically discharged outward, thereby affecting the normal work of astronauts. At the same time, in other use environments, when the bag opening is fully opened, external dust or foreign matter will enter the storage bag, causing the interior of the storage bag to be contaminated. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, one of the purposes of the present invention is to provide a storage bag that can automatically tighten the bag opening; the second purpose is to provide a vacuum compression bag that can automatically tighten the bag opening.

[0004] The technical solution adopted by the present invention to solve its technical problem is:
