The push tube 34 may be integrally formed with the three-way valve 30 or may be provided in a separated form as shown in FIG. 2B. In this figure, the three-way valve 30 is formed of a male screw and the push tube 34 is formed of a female screw. However, the push tube may be formed of a male screw and a three-way valve may be formed of a female screw. It is possible to apply the manner in which the locking is made.

In addition, the push tube 34 is a push rod coupling portion 341 is formed on any one side. The push rod coupling portion 341 is configured to correspond to the discharge pipe coupling portion 12 of the infusion discharge pipe 10 is made. That is, in the present invention, because the male thread or male-type locking protrusion is formed on the outer surface of the infusion pipe 10, the female thread-type locking protrusion is formed on the pusher coupling portion 341 of the pusher tube 34. Accordingly, the fastening portion 341 of the pusher tube includes a disc portion 342 extending to the outer surface of the pusher tube, and a joining tube portion 343 extending forward from the disc portion and having a spiral or a locking protrusion formed therein. Is done. In addition, the push rod coupling portion 341 includes a form in which the union nut is integrally coupled to the push rod.

The length from the push rod coupling portion 341 of the push rod 34 to the end introduced into the sap discharge tube is the length of the push rod when fastening the push rod coupling portion 341 of the push rod and the discharge pipe coupling portion 12 of the sap discharge tube. It is preferable that the end portion of 34 is extended to a length that can be removed from the discharge passage 11 of the infusion tube by pushing the inner plug 20 mounted on the infusion tube.

In addition, the through hole is formed at the end of the push tube 34 to push the inner plug 20, the fluid in the infusion container can be made to the three-way valve through the through hole in the tip of the push tube can be made to supply the fluid.

It is possible to facilitate the introduction of the purified air into the fluid container while making it.

In addition, the air flow path 36 is preferably to supply air through a separate space from the vertical flow path 311 for discharging the sap, but one vertical flow path may be made to discharge the fluid and the air supply at the same time. . In the case of moving the air and the sap through the same flow path, if the diameter of the flow path is not increased, the pressure inside and outside the sap container is balanced so that the air stops on the flow path, and thus sap supply may not be performed smoothly. Therefore, it is possible to prevent the occurrence of the problem by separately supplying a flow path for the air inlet and the fluid discharge. In addition, the air flow passage 36 and the vertical flow passage 311 for discharging the sap is provided by partitioning the space at an appropriate ratio inside the push tube 34, as shown in the upper air passage and the vertical flow path is in communication Through-holes are formed in two sides to allow air discharge and infusion to be made through different through-holes.

The extension tube 70 further extends the infusion discharge tube 10 in the axial direction, and a front end extension coupling part 71 and a rear end extension coupling part 72 are formed, and the shear extension coupling part 71 is an infusion solution pipe. It is coupled with the discharge pipe coupling portion 12 of (10), the extension pipe stopper 73 is temporarily mounted on the rear extension coupling portion (72). The extension tube 70 may be provided in a form formed integrally with the infusion tube 10 in addition to the separated form as shown. In addition, the separate extension tube 70 may be coupled to the infusion pipe 10 used in the existing, while extending the length of the infusion tube can be installed in the auxiliary valve and the three-way valve formed in the push tube inward. In addition, the shear extension coupling portion 71 and the rear extension coupling portion 72 formed in the extension pipe 70 may be selectively processed into a female type or a male type according to the coupling target.
