HERMETIC PRESSURE TYPE INJECTOR BY USING A CREASES CASE

摘要

A hermetic pressure type tree injection device for injecting a tree with a liquid chemical using a compression container and bellows container is provided to form simple structure, shorten the injection time by high pressure injection effect and prevent leakage of the liquid chemical during long-term storage, movement and use of the tree injection device. A hermetic pressure type tree injection device comprises: a liquid chemical container(110) with an opening part(111) at one end and an outlet(112) which is closed with a moisture barrier membrane(113) and runs parallel or perpendicular to the bottom; an injection device body(100) slidably connected to the opening part side of the liquid chemical container and having a compression container(120) to increase the interior pressure of the liquid chemical container when the liquid chemical container is pressed; an injection tube(200) with an insertion part(201) to rupture the moisture barrier membrane. The injection tube is connected to the outlet of the liquid chemical container. A bellows container(130) containing a liquid chemical is installed between the liquid chemical container and compression container and folded which the compression container is pressed.
