The filling drinking tube and the flexible packaging container body are connected to form a complete flexible packaging container. The filling drinking tube of the present invention is integrally formed of plastic, and the production cost is low; the nozzle section can be kept clean; the connection between the nozzle section and the sealing section is not easily broken due to the bending of the filling drinking tube; and the nozzle is broken. After the connection between the segment and the sealing segment, the contents of the container can be consumed, and the used flexible packaging container can be prevented from being used again; when the material is not finished drinking once, the sealing segment can be used as a cover. Sovereignty item 1. A filling drinking tube, comprising a connecting section and a nozzle section connected to the connecting section, characterized in that: an upper mouth section of the nozzle section is sleeved with an outer mouth section, and the lower end of the sealing section is The outer wall of the nozzle section is sealed and connected, and there is a gap between the outer wall of the upper half of the nozzle section and the inner wall of the sealing section; the shape and size of the inner edge of the cross section of the lower half of the nozzle section and the cross section of the sealing section. Match; the upper end of the sealing section is higher than the upper end of the nozzle section.
