Suction device and packaging container with such suction device

Patent name: Suction tube device and packing container with such suction tube device Patent applicant Shantou Hongqiao Packaging Industry Co., Ltd. Principal Applicant Address 515021 No. 32 University Road, Shantou City, Guangdong Province Inventor Luo Shize Application (Patent) No. 200510036948.3 Date of Application 2005.09.02 Certification date Approval Notice No. 1736820 Auditing announcement date 2006.02.22 Manual CD No. D0608-1 Main classification number B65D85/72 (2006.01) I Classification number B65D85/72 (2006.01) I; B65D41/32 (2006.01) I points The original application No. 1 is a suction device comprising a connection section and a suction nozzle section connected to the connection section, wherein the connection section and the suction nozzle section have a material through hole, characterized in that: the suction nozzle section is The outer half of the half sleeve is sleeved with a mouth section. The lower end of the seal section is connected with the outer wall of the suction nozzle section. The outer wall of the upper half of the suction nozzle section has a gap between the outer wall of the sealing section and the inner wall of the sealing section. The sealing section is provided with an easy-pull bar, which is easy to pull. The through holes of the surrounding material are arranged in an annular shape; the upper end of the sealing section is higher than the upper end of the suction nozzle section. Connect the suction tube device and the packaging container body to form a complete flexible packaging container. In the present invention, since the nozzle section is trapped by the sealing section and is sealed after the filling is completed, the nozzle section can be kept clean, the leakage of materials is effectively prevented, and the quality of the product is ensured; the easy-pulling strip not only facilitates the consumption of the material by the consumer, but also It can damage the suction device and prevent the used packaging container from being used again. Sovereignty item 1. A suction device comprising a connection section and a suction nozzle section connected to the connection section, the connection section and the suction nozzle section having a material through hole, characterized in that: the upper half of the suction nozzle section is sleeved A piece of mouth section is connected, and the lower end of the sealing section is sealed and connected with the outer wall of the suction nozzle section. There is a gap between the outer wall of the upper section of the suction nozzle section and the inner wall of the sealing section; the sealing section is provided with an easy-pulling strip, and the easy-pulling strip surrounds the material passage The hole is provided in a ring shape; the upper end of the sealing section is higher than the upper end of the suction nozzle section.
