Claims

[Claims for Utility Model Registration] A fixed cylinder 2 whose lower surface can be fitted and fixed to the valve component side of the injection container B, and a fixed cylinder 2 formed on a concentric circle and slidably fitted into the inner diameter part of the fixed cylinder 2. The cylinder is equipped with an outer cylinder part 3 having a locking part that is set and fixed on the fitting surface with the fixed cylinder 2 at its bottom dead center, and a contact surface 4a on the lower surface that presses down and connects the injection valve pipe 1. A cylinder part 5 with an inner cylinder part 4, and a small diameter piston cylinder 1 having a nozzle 8a on the upper end surface.
5, a piston part 9 on which a large-diameter piston cylinder 14 molded is slidable with respect to the cylinder whose top surface is open, and valves on the injection valve pipe 1 side and the inner cylinder part 4 connected to the contact surface 4a. A needle pipe 12 has a passage connecting with the housing 13 and is fixed upright from the bottom of the inner cylinder part 4 to the center hole of the small diameter piston cylinder 15.
A continuous injection device for an injection container is provided with a needle valve 17 that opens only when the piston part 9 and top dead center are on the outside of the needle pipe 12 in the center hole 15b of the small diameter piston cylinder 15 extending from the valve housing 13 to the nozzle 8a.
