Abstract:
The present invention relates to a tube vessel capable of preventing air infiltration. The tube vessel capable of preventing air infiltration according to the present invention is provided with a nozzle which is lifted and opened by the pressure of the content inside a discharge portion and the nozzle is opened only when the content is discharged. Therefore, the discharge hole of the nozzle remains in the closed state even in a state where the cap is opened, unless the content is discharged, and thus, air infiltration into the tube body through the discharge hole can be blocked so as to prevent degradation of the contents.
