Abstract:
An anti-backflow extrusion liquid container includes an elastic container for storing and extruding liquid, a spraying tube inserted into the elastic container, a first one-way valve for controlling the opening and closing of the spraying tube, and a second one-way valve for adjusting the air pressure in the elastic container. The first one-way valve is disposed in the middle of the spraying tube, and the second one-way valve is disposed at the bottom of the elastic container. The disclosure not only prevents the liquid in the guide tube from flowing back into the bottle body during the restoring process of the bottle body and thus avoiding the liquid in the bottle body from being contaminated, but also enables the bottle body to be restored quickly after pressing and thus prolonging the service life of bottle and improving work efficiency.

Claim (Index 5):
The anti-backflow extrusion liquid container according to  claim 3 , wherein the first sealing structure, the second sealing structure, the third sealing structure and the fourth sealing structure are sleeved with a sealing ring.
