Under the valve seat 13c, a tubular pipe attachment port 13d is continuously provided. And the upper end part of the suction pipe 14 is press-fit in the pipe attachment port 13d.

  In such a cylinder 13, a ball-like check valve 16 is placed and placed on the valve seat 13 c, and then a coil spring 17 is inserted and placed on the stepped portion. Thereafter, the first piston 18 is placed on the coil spring 17 and inserted into the cylinder 13.

  As shown in FIG. 2, the outlet valve 20 is placed on the first piston 18, thereby partitioning the cylinder chamber S in the cylinder 13. The outlet valve 20 has an H-shaped section in an annular shape, and presses the outer peripheral lower end against the inner peripheral surface of the cylinder 13 and presses the inner peripheral lower end slightly shorter than the outer peripheral lower end against the first piston 18 so as to face upward. The inner peripheral cylindrical portion that protrudes from the first piston 18 extends along the outer periphery of the first piston 18 with a small gap.

  On the 1st piston 18, the 2nd piston 22 which comprises the piston 21 with the 1st piston 18 is mounted. The upper part of the 1st piston 18 is inserted in the 2nd piston 22, and the upper end of the inner peripheral cylinder part of the outlet valve 20 is pressed on an inner peripheral surface.

Is provided with a taper 25f. In addition, three click protrusions 25g are provided at the lower edge of the outer peripheral surface with an interval of 90 degrees. Then, one of the click protrusions 25g is elastically fitted to the click engagement portion 23d with a click feeling, and the rotation position of the stopper member 25 is positioned at the lock position and the lock release position. Moreover, it has a knurl in the outer periphery of the collar part 25c.

  On the other hand, the support portion 23c of the stop cap 23 has a proximal end of the trigger lever 26 attached to the distal end thereof so as to be rotatable. The trigger lever 26 includes a peripheral surface portion 26b that is bent at a right angle and has a notch 26a in the bent portion, and a side surface portion 26c that is provided to face both sides thereof. An engaging recess 26d is formed downward on the inner surface of the side surface portion 26c.

  The engagement recess 26 d engages with the circular engagement protrusion 27 a of the stem 27. The stem 27 is composed of a single pipe portion 27b on the base end side provided vertically and a double pipe portion 27c on the front end side provided horizontally, which is bent into an elbow shape at approximately 90 degrees. Then, as shown in FIG. 4, the circular engaging projection 27a and the elongated rib-shaped butting projection 27d extending downward are provided on both upper sides of the single pipe portion 27b.

  The double pipe part 27c is composed of an outer cylinder part and an inner cylinder part slightly protruding from the outer cylinder part, and the cylindrical base end 28a side of the nozzle holder 28 is fitted between them as shown in FIG. A nozzle member 30 is attached to the tip end side of the nozzle holder 28, and a nozzle 30a provided in the nozzle member 30 communicates with the discharge flow path 27e in the inner cylinder portion of the double pipe portion 27c.

  The stem 27 inserts the single pipe portion 27b into the cylindrical portion 25b of the stopper member 25, and then inserts the single pipe portion 27b into the cylindrical portion 23b of the stopper cap 23 so as to cover the second piston 22, and the nozzle holder 28 is cut off from the trigger lever 26. It protrudes outward through the notch 26a. And the discharge flow path 27e of the stem 27 is connected with the flow path 22a in the 2nd piston 22, and the engagement recessed part 26d is mounted on the engagement protrusion 27a. Thereby, the stopper member 25 is attached so as to be rotatable around the stem 27.

  When not in use, the stopper member 25 is turned to the lock position shown in FIGS. 1 and 2 by touching and rotating the knurling on the outer periphery of the flange portion 25c of the stopper member 25, and the middle click of the three is clicked. The protrusion 25g is fitted to the click engagement portion 23d with a click feeling, and the stopper member 25 is set to the lock position. Then, at this time, even if an attempt is made to place the finger on the finger-hanging portion 26e and rotate the trigger lever 26, the abutting projection 27d of the stem 27 abuts on the step 25d of the stopper member 25 and the stem 27 cannot be pushed down. The rotation of the piston 26 is restricted and the pushing of the piston 21 is prevented.

  Now, when using this ejector, hold the container 10 and touch the knurling on the outer periphery of the flange 25c to rotate the stopper member 25, so that another click that is not attached to the click engaging portion 23d. One of the protrusions 25g is fitted to the click engagement part 23d with a click feeling, and the stopper member 25 is set to the unlock position.

  Thereafter, when a finger is put on the finger-hanging portion 26e and the trigger lever 26 is rotated counterclockwise as shown in FIG. 5, the abutting projection 27d of the stem 27 enters the escape recess 25e of the stopper member 25, and the stem 27 The stem 27 can be pushed down without hitting it, and the piston 21 is pushed against the coil spring 17 with the outlet valve 20 to increase the pressure in the cylinder chamber S.

  When the pressure in the cylinder chamber S exceeds a certain level, the outlet valve 20 is opened to create a gap with the first piston 18, and the contents of the cylinder chamber S are put into the second piston 22. It enters into the discharge flow path 27e of the stem 27 through the passage 22a, and discharges to the outside from the nozzle hole 30a at the tip through the stem 27. Then, the first piston 18 is finally applied to the cylinder 13 and stopped.

  When the contents of the cylinder chamber S are discharged and the pressure in the cylinder chamber S decreases, the outlet valve 20 is pushed down, the outlet valve 20 is pressed against the first piston 18 again, and the finger is released from the finger hooking portion 26e. The piston 21 and the stem 27 are raised by the urging force of the coil spring 17, and the trigger lever 26 is rotated clockwise to return to the original state.

  Then, the pressure in the cylinder chamber S becomes negative, the ball valve 16 is opened, and the contents of the container 10 are sucked into the cylinder chamber S through the suction pipe 14. Then, when the pressure in the cylinder chamber S becomes atmospheric pressure, the ball valve 16 falls again onto the valve seat 13c and closes the suction port.

  Therefore, when the trigger lever 26 is rotated, the contents can be ejected again from the nozzle 30a. By repeating this operation, the container 10 can be discharged any number of times until the content of the container 10 is exhausted.

  When suspending use, touch the knurl on the outer periphery of the flange 25c to rotate the stopper member 25 around the reciprocating direction of the piston 21, and push down the stem 27 again as the lock position shown in FIGS. This prevents the trigger lever 26 from rotating.
