The valve 29 is opened when the pump B is depressed, so that the content liquid is discharged. It is discharged and closed when the pump is raised. When the subdivision discharger D is removed, the valve 29 prevents the liquid in the inner cylinder 24 of the liquid storage member 20 from leaking.

The valve holding member 21 has an upper wall 30 and a side peripheral wall 31 as shown in FIGS.
A valve support cylinder 32 is provided upright on the upper surface of the. The valve support cylinder 32 is composed of an inner cylinder 33 rising from the inner end edge of the upper wall 30 and an outer cylinder 35 positioned outside with the valve fitting groove 34 disposed therebetween. A projection 36 is provided.

A conical cylinder 38 having a plurality of flow holes 37 is vertically provided below the inner cylinder 33, and a shielding plate 39 is continuously provided at a lower end thereof. At a predetermined position of the side peripheral wall 31,
A handle 40 is protruded. The side peripheral wall 31 of the valve holding member 21 is fitted to the inner peripheral surface of the outer cylinder 25 of the liquid storage member 20, and a measuring chamber 41 is formed by the liquid storage member 20 and the valve holding member 21.

The slit valve 22 is made of an elastomer or other soft material, and has a top wall 42 and a side peripheral wall 44 having a flange 43 protruding therefrom. Top wall 42
Has a concave spherical surface at the center, and a cross-shaped slit 45 is engraved at the center. Slit valve 2
The second side peripheral wall 44 is inserted into the valve insertion groove 34 and held by the valve support cylinder 32.

The valve retainer 23 comprises an annular retainer plate 46 and a side peripheral wall 47, and a lower end of the side peripheral wall 47 has an outer cylinder 35.
A locking ridge 48 is formed to engage with the lower side of the bulging ridge 36 so as to press the flange 43 of the slit valve 22 against the upper surface of the outer cylinder 35.

To assemble the subdivision discharger D, the slit valve 22 is inserted with its side peripheral wall 44 into the valve fitting groove 34 of the valve support cylinder 32 and the valve retainer 23 is connected to the valve support cylinder 3.
2 by fitting into the outer cylinder 35
2 and then the valve holding member 21 is fitted to the liquid storage member 20 to assemble the subdivision discharger D. The discharge container of the present invention is completed by attaching the subdivision discharger D to the stem 9.

As shown in FIG. 1, the overcap E comprises a top wall 50 and a side peripheral wall 51, and a bulge which engages with the locking ring 7 of the shoulder 2 when the lid is closed. Ring ring 52
Is provided.

Next, a description will be given, with reference to the drawings, of the mode of use and the function and effect of the discharge container. In discharging the content liquid, as shown in FIG. 5, when the subdivision discharger D is depressed with the handle 40 with the stopper 17 pulled out, the piston member descends through the stem 9 and the content liquid in the cylinder 8 is discharged. It is discharged into the measuring chamber 41 and stored. Handle 40
When the hand is released, the piston member rises due to the bias of the spring, and when the piston member reaches the uppermost stroke position, the stopper 17
Is pushed in, the locking rod 16a is moved to the bottom wall 2 of the liquid storage member 20.
6 and dispenser D maintains its uppermost stroke position.

Next, by holding the discharge container and directing the subdivision discharger D to a desired position and pressing the slit valve 22, the slit valve 22 is deformed and the slit 45 is opened, so that a small amount of the content liquid is extruded. At this time, the piston member is locked by the stopper 17 and does not move.

Next, when the content liquid in the measuring chamber 41 has been used up, the stopper 17 is pulled out and the subdivision discharger D is pushed down, so that the content liquid can be discharged into the measuring chamber 41 again. Can be repeatedly dispensed.

The case where the subdivision discharger D is used after removal will be described. First, with the subdivision discharger D attached, it is pushed down to discharge and store the content liquid in the measuring chamber 41. Next, when the subdivision discharger D is removed from the stem 9 and carried to a required place, and the slit valve 22 is pressed, the slit 45 is opened and a small amount of the liquid can be discharged.

Next, a modified embodiment relating to the stopper will be described. In the above embodiment, the stopper 1 is provided near the upper end of the mounting cap C to prevent the piston member from being hindered.
7 is provided, but as a means for locking the liquid reservoir member 20 at the uppermost position, an embodiment in which the configuration of the upper peripheral surface 14a of the mounting cap C and the outer periphery of the outer cylinder 25 of the liquid reservoir member 20 is changed The differences will be mainly described.

As shown in FIG. 6, on the outer peripheral surface of the outer cylinder 25 of the liquid reservoir member 20, a number of ridges 60 extending in the vertical direction are provided at equal intervals. Upper peripheral surface 1 of mounting cap C
4a, a step portion 61 which can be locked to the lower end of the ridge 60 when the subdivision discharger D is raised to the uppermost stroke position.
Is formed, and on the protruding surface 62,
A concave groove 63 that engages with the ridge 60 is engraved so that the subdivision discharger D can slide up and down.

In use, a fixed amount of the liquid is discharged into the measuring chamber 41 by depressing the subdivision discharger D. Next, when the subdivision discharger D rises to the uppermost stroke position, the lower end of the ridge 60 slightly rises above the concave groove 63. At that time, when the subdivision discharger D is rotated,
The lower end of the ridge 60 can be locked to the step 61, so that the piston member can be prevented from being hindered.

[0028]

The present invention has the following effects because it is configured as described above. Since the subdivision discharger is detachably attached to the pump of the discharge container, a small amount of the content liquid can be discharged. When the subdivision discharger is detached and used, it is lightweight, so that the handling is further simplified.
