When the discharge plug 30 is thus set at the dischargeable position and the inner annular seal portion 34 is released from the liquid-tight engagement with the inner peripheral surface of the opening 12, the outer annular seal 35 is closed. It is liquid-tightly fitted to the inner peripheral surface of the opening 12, and closes the annular gap formed between the constricted surface 31A of the plug main body 31 and the inner peripheral surface of the opening 12 from the outside. As a result, the content inside the cylindrical portion 11 is always discharged from the discharge path L via the communicating hole 33 by the inverted container body 201, and the narrow discharge area of the discharge hole 32 formed on the central axis of the plug body portion 31. from the range of to the surface to be coated.

The discharge plug 30 is movable between the discharge sealing position and the dischargeable position described above. Note that the discharge seal position is not a single fixed point, but is a concept that includes all points within a certain range other than the dischargeable position. It should be noted that the dischargeable position does not have to be one fixed point.

As shown in FIGS. 13 and 14, the metering plug 40 is a plastic molded body such as polypropylene, and is disposed inside the cylindrical member 10. It is connected to the discharge plug 30 so as to be movable up and down in conjunction with the above-mentioned pulling up/pushing movement.

When the discharge plug 30 is pulled up, the metering plug 40 is separated from the partition wall 22 of the inner plug 20 to form an inflow path R of the content with the partition wall 22, and the content of the container main body 201 is measured. It is set to a weighable position that allows the material to be supplied from the supply hole 23 of the partition wall 22 to the weighing space 13 .

At this time, as described above, the inner plug 20 forms the fitting seal portion 27 around the supply hole 23 formed in the partition wall 22, and the metering plug 40 set at the above metering seal position is The tip of a skirt-shaped seal portion 42 extending from the outer periphery of the top surface portion 41A of the plug body 41 is liquid-tightly fitted over the entire inner periphery of the fitting seal portion 27 to form the partition. The supply of contents from the supply holes 23 in the wall 22 is disabled.

As shown in FIG. 14A, the metering plug 40 has a guide tube 43 surrounded by a skirt-shaped seal portion 42 and concentric with the skirt-shaped seal portion 42 on the lower surface of the top surface portion 41A of the plug main body portion 41. Prepared vertically. The measuring plug 40 is movable up and down by loosely inserting a guide cylinder 43 around the small diameter guide portion 28B of the guide post 28 provided in the inner plug 20, and the inner surface of the guide cylinder 43 is arranged along the outer surface of the small diameter guide portion 28B. The guide tube 43 is guided in its vertical movement by , and the end surface of the guide cylinder 43 moved to the metering seal position is brought into contact with the annular stepped surface 28C of the inner plug 20 to limit its movement (FIG. 3).

The metering plug 40 includes an engaging portion 44 that protrudes upward from the central portion of the upper surface of the top surface portion 41A of the plug main body portion 41 . The engaging portion 44 is composed of a shaft portion 44A extending from the top surface portion 41A and a bulging portion 44B provided at the upper end portion of the shaft portion 44A, and can be engaged with the spring portion 50 as described later.

The spring portion 50 is interposed between the discharge plug 30 and the metering plug 40 inside the cylindrical member 10, as shown in FIGS. The discharge plug 30 , the metering plug 40 and the spring portion 50 are arranged in series along the axial direction of the tubular portion 11 of the tubular member 10 .

Here, in the present embodiment, as shown in FIGS. 10 to 12, the discharge plug 30 is integrally provided with a spring portion 50 at the end portion of the plug main body portion 31 near the metering plug 40 . The spring portion 50 is a plastic molded body such as polypropylene integrally molded with the discharge plug 30, and the annular portion 51 having approximately the same outer diameter as the outer peripheral surface of the plug main body portion 31 of the discharge plug 30 is attached to the plug. A plurality of spring pieces 52 are provided at the end portion of the body portion 31 near the metering plug 40 and hang down in the axial direction of the plug body portion 31 from a plurality of positions spaced apart in the circumferential direction of the annular portion 51 . Each spring piece 52 includes a vertical piece portion 52A extending downward along the outer peripheral surface of the plug body portion 31 of the discharge plug 30, and a horizontal piece portion extending from the lower end portion of the vertical piece portion 52A to the center side of the plug body portion 31 in the radial direction. The vertical piece 52A and the horizontal piece 52B are L-shaped.

The vertical piece portion 52A and the horizontal piece portion 52B that form each spring piece 52 of the spring portion 50 surround the bulging portion 44B that constitutes the engaging portion 44 of the metering plug 40 from the outside so that they can be retained. embrace to When receiving the pushing force of the discharge plug 30 pushed into the tubular portion 11 of the tubular member 10 under the condition that the metering plug 40 is set at the metering seal position, each spring piece 52 is pushed laterally. The piece 52B is brought into contact with the upper surface of the top surface 41A of the plug main body 41 of the metering plug 40 so that the plug main body 41 can be pushed in the axial direction, and the vertical piece 52A is compressed and elastically deformed. .

At this time, under the condition that the metering plug 40 is set to the metering seal position, each spring piece 52 of the spring portion 50 provided at the end of the plug main body 31 of the discharge plug 30 is elastically deformable as described above. Therefore, as shown in FIG. 6, there is a vertical piece between the bottom surface of the end of the plug body 31 (the surface on the container body 201 side) and the top surface of the bulging portion 44B of the engagement portion 44 of the measuring plug 40. It is necessary to secure a clearance δ corresponding to the compression of 52A.

The discharge container 200 has a cap (not shown) detachably attached to the container body 201 . When the cap is attached to the container main body 201, the tip protrusion 30P ( 2). As a result, the discharge plug 30 can be pulled up from the inside of the tubular portion 11 of the tubular member 10 in conjunction with the removal of the cap from the container body 201 . After that, the cap is separated from the tip protrusion 30P of the discharge plug 30 and removed from the container main body 201 and the discharge tool 100. As shown in FIG.

Therefore, according to the discharge tool 100, by pulling up the discharge plug 30, the discharge plug 30 is set to the discharge sealing position, and the measuring plug 40 receives the lifting force of the discharge plug 30 and can be set to the measuring possible position. As a result, the content of the container body 201 can be supplied to the measuring space 13 inside the cylindrical portion 11 of the cylindrical member 10 by the inverted state of the container body 201, and a fixed amount of content can be measured. be. On the other hand, when the discharge plug 30 is pushed, the metering plug 40 receives the pushing force of the discharge plug 30 and is set at the metering seal position, while the spring pieces 52 of the spring portion 50 that receive the pushing force of the discharge plug 30 By flexing and setting the discharge plug 30 to the dischargeable position, the content weighed in the measuring space 13 inside the cylindrical portion 11 of the tubular member 10 can be discharged from the discharge hole 32 of the discharge plug 30. be made.

However, in the discharge tool 100, when the discharge plug 30 is pushed in, the measurement plug 40 receives the pushing force of the discharge plug 30 and is set at the measurement seal position. Each spring piece 52 of the spring portion 50 that received the spring portion 50 is bent and the discharge plug 30 is set to the dischargeable position, so that the content weighed in the weighing space 13 inside the tubular portion 11 of the tubular member 10 is discharged. Dispensable.

At this time, the spring force of each spring piece 52 of the spring portion 50 is greater than the fitting force for fitting the plug main body portion 41 to the fitting seal portion 27 of the inner plug 20 when the metering plug 40 is set at the metering seal position. set to be large. If the spring force is smaller than the fitting force, the discharge seal by the discharge plug 30 is opened while the metering seal by the meter plug 40 remains incomplete, and the measurement seal cannot be completely sealed.

That is, the discharge tool 100 constituting the discharge container 200 moves the discharge plug 30 between the maximum lifting stroke end C in the metering possible state (FIG. 4) and the maximum pushing stroke end E in the discharging execution state (FIG. 7). It is made movable and performs a dispensing operation as follows.

(1) Standby state (Fig. 3)
When the dispensing container 200 is in storage with a cap (not shown) attached and the dispensing tool 100 is in a standby state, the dispensing tool 100 cannot measure or dispense. The discharge plug 30 is set at a standby position B where the end face 31P of the plug main body 31 protrudes from the end face A of the opening 12 of the tubular member 10 to the outside by a certain length h. At this time, the discharge plug 30 is set to the discharge seal position where the inner annular seal portion 34 of the plug main body 31 is liquid-tightly fitted to the inner peripheral surface of the opening 12 of the tubular portion 11 of the tubular member 10 . (FIG. 3), and the discharge of the contents from the discharge hole 32 is stopped.

At this time, the metering plug 40 is set to the metering seal position where the skirt-shaped seal portion 42 of the plug main body 41 is liquid-tightly fitted to the fitting seal portion 27 of the inner plug 20 (FIG. 3). The content is prevented from flowing into the measuring space 13 of the tubular member 10 through the supply hole 23 of the partition wall 22 .

(2) Weighable state (Fig. 4)
As the cap (not shown) of the discharge container 200 is removed from the container body 201, the end surface 31P of the discharge plug 30 is lifted from the standby position B in (1) above by a predetermined lifting stroke S0. When set to the maximum lifting stroke end C (FIG. 4), the discharge plug 30 is still maintained at the discharge sealing position (FIG. 4), and the discharge of the contents from the discharge hole 32 is stopped.

At this time, the metering plug 40 engages the engaging portion 44 of the metering plug 40 with the spring pieces 52 of the spring portion 50 integrally provided with the metering plug 30 . In conjunction with the lifting of the discharge plug 30 by receiving the aforementioned lifting force, the tip of the skirt-like seal portion 42 of the measurement plug 40 moves away from the fitting seal portion 27 of the inner plug 20 to the meterable position (FIG. 4). set. The top surface 41A of the plug main body 41 of the metering plug 40 has a bulging portion 44B that constitutes the engaging portion 44 of the plug main body 41 with respect to the lateral piece 52B of each spring piece 52 of the spring portion 50. It is separated from the horizontal piece portion 52B of each spring piece 52 so as to have an axial play gap G (FIG. 4). In the discharge tool 100, G=0 may be used.

As a result, the skirt-shaped seal portion 42 of the stopper main body portion 41 of the metering stopper 40 is separated from the fitting seal portion 27 of the inner stopper 20 to form an inflow path R for the contents between itself and the inner stopper 20, thereby It enables the contents of the main body 201 to be supplied from the supply hole 23 of the partition wall 22 to the measuring space 13 of the tubular member 10 . However, unless the container main body 201 is overturned, the supply of the above contents to the measuring space 13 of the cylindrical member 10 is not executed.

(3) Weighing execution state (Fig. 5)
The container body 201 set in the weighable state of (2) above is turned upside down (FIG. 5). As a result, the contents of the container body 201 pass through the supply hole 23 of the partition wall 22 and the inflow route R (arrow in FIG. It is fed into the metering space 13 inside 11 . At this time, the discharge plug 30 is maintained at the discharge seal position.

In addition, the measuring plug 40 descends in the measuring space 13 as the container main body 201 is turned upside down and the content flows into the measuring space 13. The play gap G generated with respect to the horizontal piece portion 52B of 52 is eliminated.

(4) Weighing completed state (Fig. 6)
In the discharge tool 100 in which the content is supplied to the measuring space 13 inside the cylindrical portion 11 of the cylindrical member 10 in (3) above, a discharge plug 30 protruding from the opening 12 of the cylindrical portion 11 to the outside world. The end face 31P of the plug main body 31 at is pressed against the coated surface F such as the scalp. By this pressing external force, the end surface 31P of the discharge plug 30 is pushed by the first pushing stroke S1 from the maximum lifting stroke end C in (2) and (3) above, and set to the stroke intermediate point D (Fig. 6) The discharge plug 30 is still maintained at the discharge seal position where the inner annular seal portion 34 of the plug main body 31 is liquid-tightly fitted to the inner peripheral surface of the opening 12 of the cylindrical portion 11 of the cylindrical member 10 . be done. The metering plug 40 receives the pushing force of the first pushing stroke S1 of the discharge plug 30, and is interlocked with the pushing of the discharge plug 30. The setting is changed to the metering seal position in which the fitting seal portion 27 is liquid-tightly fitted (FIG. 6). The pushing stroke of the discharge plug 30 is such that the leading end surface of the guide cylinder 43 of the metering plug 40 collides with the annular stepped surface 28C of the inner plug 20 as described above, and the metering plug 40 is urged to its movement limit. Along with this, the stroke is temporarily stopped at the midpoint D of the stroke.

As a result, the contents of the container body 201 cannot be supplied from the supply hole 23 of the inner plug 22 to the measuring space 13 of the cylindrical member 10, and the measuring of a certain amount of the contents to the measuring space 13 is completed. do.

At this time, the discharge plug 30 is in the discharge sealing position, and the contents that have been weighed into the measurement space 13 are not discharged from the discharge hole 32 of the discharge plug 30 unexpectedly.

(5) Discharge execution state (Fig. 7)
When the end surface 31P of the plug main body 31 of the discharge plug 30 is further pressed against the coated surface F such as the scalp in the discharge tool 100 that has been weighed in (4) above, the further pressing external force causes the discharge plug 30 to move. The end face 31P is pushed by the second pushing stroke S2 from the stroke middle point D in (4) above to reach the maximum pushing stroke end E (the maximum pushing stroke end E is the same as the end face A of the opening 12 in the cylindrical portion 11). 7), the spring pieces 52 of the spring portion 50 which receive the further pushing force of the discharge plug 30 bend. The discharge plug 30 opens the discharge path L so that the inner annular seal portion 34 of the plug main body 31 can discharge the content that has been measured into the measurement space 13 to the discharge hole 32 side. position (FIG. 7).

As a result, the content weighed into the weighing space 13 is discharged from the discharge hole 32 via the discharge path L and the communication hole 33 of the discharge plug 30, and is applied to the surface F to be coated such as the scalp.

At this time, the metering plug 40 is maintained at the metering seal position described in (4) above, and no new content is supplied to the metering space 13 .

(6) Dispensing interrupted state (same state as metering completion state in Fig. 6)
When the end surface 31P of the plug main body portion 31 of the discharge plug 30 is separated from the surface to be coated F such as the scalp in the discharge tool 100 during measurement in (5) above, each spring piece 52 of the spring portion 50 presses and exerts an external force. The restoring force of the deflection due to disappearance is exerted on the discharge plug 30 . The discharge plug 30 receives this restoring force and is pushed out from the maximum push stroke end E by the second push stroke S2 described above, and is returned to the stroke intermediate point D in (4) or its vicinity, and the discharge seal is formed. position (Fig. 6). In addition, when the spring portion 50 integrated with the discharge plug 30 that receives the restoring force is elastically moved in the axial direction from the metering plug 40 by the restoring force, the horizontal piece portion of each spring piece 52 in the above (2) The axial play gap G generated between 52B and the top surface portion 41A of the plug main body portion 41 of the metering plug 40 can be formed again.

As a result, the discharge of the contents from the discharge hole 32 of the discharge plug 30 is interrupted. By repeating the above (5) and (6), the content weighed in the weighing space 13 can be dispensed from the discharge hole 32 .

Therefore, according to this embodiment, the following effects are obtained.
(a) The discharge tool 100 has a spring portion 50 interposed between the discharge plug 30 and the metering plug 40 inside the tubular member 10, and the discharge plug 30, the metering plug 40 and the spring portion 50 are arranged in series along the axial direction of the tubular portion 11 of the tubular member 10 .

Subsequently, when the further pressing force of the discharge plug 30 exceeds the spring force of the spring portion 50, the spring portion 50 bends and the discharge plug 30 is set at the dischargeable position. As a result, it is possible to ensure the measurement discharge operation (b) described above by the discharge tool 100 .

(d) Dispenser 100 is adapted so that the spigot 30 is movable between the maximum withdrawal stroke end C and the maximum push stroke end E; When the discharge plug 30 is at the maximum lifting stroke end C, the discharge plug 30 is set at the discharge sealing position, the metering plug 40 is set at the metering possible position, and the discharge plug 30 is moved from the maximum lifting stroke end C by an external force. When the discharge plug 30 is pushed in by the first push stroke and set at the stroke midpoint D, the discharge plug 30 is still maintained at the discharge seal position, and the metering plug 40 receives the pushing force of the discharge plug 30 to reach the meter seal position. , and when the discharge plug 30 is pushed by the second push stroke from the stroke middle point D by a further external force and set to the maximum push stroke end E, the further pushing force of the discharge plug 30 is changed to The spring portion 50 receiving the force is flexed and the discharge plug 30 is reset to the dischargeable position, the metering plug 40 is still maintained at the metering seal position, and the discharge plug 30 receives the restoring force of the deflection of the spring portion 50 due to the disappearance of the external force. At this time, the discharge plug 30 is returned from the maximum pushing stroke end E to the stroke intermediate point D, and the discharge plug 30 is set at the discharge sealing position. As a result, it is possible to ensure the measurement discharge operation (b) described above by the discharge tool 100 .

(e) In the discharge tool 100, the discharge plug 30 is integrally provided with a spring portion 50 consisting of a plurality of spring pieces 52 hanging down from a plurality of positions in the circumferential direction of the end of the plug main body 31 near the metering plug 40, and each spring piece Reference numeral 52 is the axial direction of the tubular portion 11 of the tubular member 10, and can hold the engaging portion 44 of the metering plug 40 so as to prevent it from slipping off, and can press the plug main body portion 41 of the metering plug 40 in the axial direction. to This makes it possible to easily provide the spring portion 50 of (a) described above.

(f) has a cap detachably attached to the container body 201; When the discharge tool 100 is used, the discharge plug 30 can be lifted in conjunction with the removal of the cap from the container body 201. The discharge plug 30 can be easily set to the maximum lifting stroke end C, and the discharge tool 100 can be lifted. You can start using it.
