  Although details will be described later, as shown in FIG. 1A, the first piston 8c and the second piston 9b are in contact with each other before discharging the content liquid, but as shown in FIG. When the two are separated in the front-rear direction, an air chamber R2 for containing air is formed between the first piston 8c and the second piston 9b and between the outer cylindrical wall 6a and the shaft portion 9a. Be done.

  The operation member 10 is provided with an outer connecting cylinder 10a that surrounds the inner connecting cylinder 9d. On the inner peripheral surface of the outer connecting cylinder 10a, there are provided longitudinal ribs 10b that fit into the longitudinal grooves 9e, and claws 10c that fit into the recesses 9f. The length in the front-rear direction of the claw portion 10c is shorter than the length in the front-rear direction of the recess 9f, and the operation member 10 is slightly movable in the front-rear direction with respect to the plunger 9. Further, as shown in FIG. 1B, a disc wall 10d is provided at the rear of the outer connecting cylinder 10a. The disk wall 10 d is provided with an air introduction hole 10 e communicating with the air hole 9 c of the plunger 9. In the central portion of the disk wall 10d, a large diameter cylindrical portion and a small diameter cylindrical portion provided in front of this cylindrical portion are connected, and the operation member 10 is forward of the plunger 9 A seal portion 10 f is provided to close the air hole 9 c when the air hole 9 c is moved. The cylindrical portion of the seal portion 10f enters a recess provided inside the shaft portion 9a, and when the operation member 10 moves back and forth with respect to the plunger 9, this portion functions as a guide .

  Next, the procedure for pouring out the content liquid from the liquid discharge container 1 using the above-described discharge tool 5 will be described. First, as shown in FIG. 1, the female screw portion 2 f of the container body 2 is fitted to the male screw portion 6 e of the discharge tool main body 6.

  Then, in a state in which the finger hook portion 6f is supported by the finger, the disk wall 10d is pressed from the rear toward the front. As a result, the pushing member 8, the plunger 9, and the operation member 10 move forward with respect to the discharge tool main body 6, and accordingly, the front end 8b of the pushing member 8 points the flange 4b of the stem 4 forward. And press to move the stem 4 forward.

  In the stem 4 moved forward, the communication hole 4e communicates with the liquid chamber R1 when the flange 4b abuts on the piston 3 as shown in FIG. When the disk wall 10d is subsequently pressed, the piston 3 pressurizes the liquid chamber R1, and the content liquid in the liquid chamber R1 is discharged from the front opening 4g through the communication hole 4e and the internal passage 4f. As the piston 3 advances, air is introduced into the space formed in the rear of the piston 3 through the vent holes 6d and the grooves provided in the male screw 6e, so movement of the piston 3 is impeded. There is nothing to do.

  Here, as shown in FIG. 3, even if the operation member 10 and the like are pushed to the end (until the partition wall 2b and the piston 3 abut), part of the content liquid stored in the liquid chamber R1 is an internal passage It will remain in 4f. In this state, the communication hole 4e is closed by the peripheral wall 2d provided at the edge of the opening 2c.

  In order to discharge the content liquid remaining in the internal passage 4f, the operating member 10 is moved rearward as shown in FIG. Here, since the operation member 10 is slightly movable in the front-rear direction with respect to the plunger 9 due to the relationship between the recess 9 f and the claw portion 10 c, the operation member 10 is moved backward with respect to the plunger 9 in advance. Become. As a result, the seal portion 10f moves rearward with respect to the air hole 9c, and the air hole 9c is opened. When the operating member 10 is moved rearward as it is, the plunger 9 is also moved rearward as shown in FIG. 4 to form a space (air chamber R2) formed between the first piston 8c and the second piston 9b. The air is taken in from the outside through the air inlet hole 10e and the air hole 9c.

  Thereafter, as shown in FIG. 5, when the operating member 10 is moved forward, the seal portion 10f closes the air hole 9c and the plunger 9 moves forward, and the second piston 9b pressurizes the air chamber R2. Then, the pressurized air is fed to the internal passage 4f through the gap between the inner cylindrical wall 8a and the shaft 9a as shown by the arrow in FIG. 5, so the content liquid remaining in the internal passage 4f Can be discharged from the front opening 4g.

  By the way, since the liquid discharge container 1 of the present embodiment is compatible with the male screw 2e and the female screw 2f in the container body 2, as shown in FIG. 6, the male screw 2e in one container body 2 is used. A plurality (three in FIG. 6) can be connected in series by connecting the female screw parts 2 f of the other container main body 2. Also, in this state, the recess 4 h in one stem 4 fits into the rear end 4 d in the other stem 4, so moving the one stem 4 forward also brings the other stem 4 together. Moving. And since the internal passage 4f in one stem 4 and the internal passage 4f in the other stem 4 communicate with each other, the content liquid accommodated in one liquid discharge container 1 passes through the one internal passage 4f. After that, it flows into the other internal passage 4 f and is finally discharged from the stem 4 located at the frontmost position. As described above, when a plurality of liquid discharge containers 1 are connected, the contents of all the liquid discharge containers 1 are discharged from the most front stem 4 by moving the stem 4 at the rear end forward. Can. In addition, since air is introduced into the space formed at the rear of the piston 3 as the piston 3 advances, since the air is introduced through the groove provided in the male screw portion 2e, the movement of the piston 3 is not hindered.

  Therefore, even when it is necessary to discharge the content liquid from a plurality of liquid discharge containers 1, if these are connected in series as shown in FIG. 7 and attached to the discharge tool 5, the content liquid from one liquid discharge container 1 is In the same manner as in the case of discharging ink, all the contents can be discharged at one time. In FIG. 7, the two liquid discharge containers 1 are connected to the container 21 containing another content liquid in advance together with the agitating ball 20, and the content tool is discharged by the discharge tool 5. Shows the situation.

  In order to fill the liquid discharge container 1 with the content liquid, for example, the filling machine M shown in FIG. 8 may be used. In FIG. 8, the symbol M1 is a container main body holder for holding the container main body 2, the symbol M2 is a piston holder for holding the piston 3, the symbol M3 is a filling nozzle, the symbol M4 is a container main body support, and the symbol M5 is a stem It is a pedestal for.

  First, as shown in FIG. 8A, the container body 2 is held by the container body holder M1. At this time, the piston holder M 2 abuts on the rear end of the piston 3, the filling nozzle M 3 is inserted from the rear of the stem 4, and the stem cradle M 5 abuts on the front end of the stem 4.

  Next, as shown in FIG. 8 (b), the container main body holding tool M1 is advanced to abut the container main body 2 against the container main body receiving stand M4. Further, as the container main body holding tool M1 is advanced, a liquid chamber R1 communicating with the communication hole 4e is formed between the partition 2b and the piston 3 so that the content liquid is supplied from the filling nozzle M3. Fill the liquid chamber R1 with the content liquid.

  Then, as shown in FIG. 8C, the stem pedestal M5 is moved in the direction approaching the filling nozzle M3. As a result, the communication hole 4 e is positioned rearward of the piston 3, so that the liquid chamber R 1 can be maintained in a liquid tight state. In addition, after removing the liquid discharge container 1 from the filling machine M, it is preferable to remove the content liquid adhering to the stem 4 by air blow, washing | cleaning, etc., as shown in FIG.8 (d).

  As shown in FIG. 8 (d), the front end (lower end in FIG. 8 (d)) of the tubular wall 4a is outside the liquid discharge container 1 before discharging the content liquid (normal time) as shown in FIG. 8 (d). The rear end of the tubular wall 4a (upper end in FIG. 8 (d)) is the same as or frontward of the rear end of the outer cylinder 2a. It is preferred to be located. That is, in this state, since the tubular wall 4a is fitted inside the outer cylinder 2a, the tubular wall 4a is not carelessly touched, and it is possible to prevent the discharge of the content liquid which is not intended.

  The liquid discharge container and the discharge tool of the present invention are not limited to the embodiments described above, but include various modifications. For example, in the embodiment described above, the female screw portion 2 f and the male screw portions 2 e and 6 e are shown as the engaging portion and the engaged portion which connect the liquid discharge containers 1 with each other or the liquid discharge container 1 and the discharge tool 5. For example, various combinations can be employed such as a combination of a flexible claw and a recess with which the claw engages, and a combination of a protrusion and a circumferential groove into which the protrusion is fitted (bayonet). .
