Definitions
- the invention relates to the field of logistics and transportation, and in particular to a fluid discharge system and a fluid discharge method.
- the foreign patent IL156984A discloses a sealed bag liquid, and the main part thereof is a sealed soft body container which is formed by hot-melt welding or high-frequency welding using a PVC coated cloth or a PE film; the two ends of the sealed soft body container are respectively set There are an inlet valve and an outlet valve; the main body also includes an auxiliary air bag, and the air bag is provided with an inflated air inlet.
