NOZZLE CAP FOR CONTAINER OF LIQUID TO BE INJECTED INTO TRUNK

摘要

PROBLEM TO BE SOLVED: To provide a nozzle cap for injecting a chemical liquid into a trunk to prevent the withering of pine tree. SOLUTION: The objective nozzle cap for a plastic container injects a chemical liquid from the container into a hole of a trunk having a diameter of about 6 cm and a depth of about 4-9 cm. The nozzle is produced by connecting a circular cylinder to a broad opening of a tapered trumpet and the total length of the nozzle is about 10-11 cm. The liquid injection port for injecting the chemical liquid into the hole is formed by bending and cutting the deepest part 20B of notch in the middle of the trumpet. The cap is composed of (A) a circular cylindrical finger-pressing rod, (B) a notched part having a notch along the outer circumference of the circular cylinder and composed of the upper half above the deepest part of the notch belonging to the finger-pressing rod A and the lower half below the deepest part of the notch belonging to the following injection pipe introducing part C, (C) a cylindrical injection pipe introducing part having a chemical liquid injection port by cutting, (D) a gradient part having gradually increasing outer diameter, (E) a curved part and (F) a female screw lid connected with each other in the order from the upside downward. The chemical liquid injection work can be stabilized and facilitated and the chemical injury caused by the leakage of the liquid can be mitigated by the use of the cap.
