The movement limit (movement limit position) to the measurement seal side of the measurement plug 40 is regulated.

  As shown in FIG. 3, the discharge plug 30 is a plastic molded body such as polypropylene, and is supported in the opening 12 of the cylindrical portion 11 of the cylindrical member 10 so as to be movable up and down, and inside the cylindrical portion 11. The discharge path L of the contents (see FIG. 7) is exposed so that it can project to the outside through the opening 12 and allows the measuring space 13 inside the cylindrical portion 11 to communicate with the outside by the inverted body of the container body 201. ) Is formed between the inner peripheral surface of the opening 12 and a generally rod-shaped plug body 31. The plug main body 31 has a constricted surface 31A having a slightly smaller diameter than the opening 12 of the cylindrical portion 11 in a certain range on the upper end side of the outer peripheral surface, and the constricted surface 31A is the inside of the opening 12 of the cylindrical member 10. The annular gap formed between the circumference and the circumference is referred to as the above-described discharge path L.

  The discharge plug 30 forms a discharge hole 32 on the central axis of the plug main body 31 along the axial direction of the cylindrical portion 11 in the cylindrical member 10, and the plug main body 31 extends from the opening 12 of the cylindrical portion 11. The discharge hole 32 is provided in the end surface 31P projecting to the outside, and extends in the radial direction from the discharge hole 32 at a plurality of circumferential positions (for example, four positions) in the axial intermediate portion of the plug body 31. In addition, a communication hole 33 is provided in the constricted surface 31A of the plug body 31. The discharge plug 30 is provided at two positions on the outer peripheral surface of the plug main body 31, the inner side and the outer side sandwiching the constricted surface 31 </ b> A where the communication hole 33 opens from both sides along the axial direction of the cylindrical part 11.

  The discharge plug 30 is pulled up from the inside of the tubular portion 11 of the tubular member 10 in the upper end direction, which is one end direction along the axial direction of the tubular portion 11, and the inner annular seal portion 34 of the plug main body portion 31 is pulled up. When the discharge seal position is set so as to be fluid-tightly fitted to the inner peripheral surface of the opening 12 in the cylindrical portion 11, the continuity between the measurement space 13 inside the cylindrical portion 11 and the discharge path L is established. Close

  On the other hand, the discharge plug 30 is pushed inside the tubular portion 11 of the tubular member 10, and the inner annular seal portion 34 of the discharge plug 30 is liquid with the inner peripheral surface of the opening 12 in the tubular portion 11. When set to a dischargeable position where the close fitting is released, the measurement space 13 inside the cylindrical portion 11 and the discharge path L are electrically connected. In this way, when the discharge plug 30 is set at the dischargeable position and the inner annular seal portion 34 is released from the liquid-tight fit with the inner peripheral surface of the opening 12, the outer annular seal 35 is The inner circumferential surface of the opening 12 is fitted in a liquid-tight manner, and the annular gap formed between the constricted surface 31A of the plug body 31 and the inner circumferential surface of the opening 12 is closed to the outside. As a result, the contents inside the cylindrical portion 11 are discharged from the discharge path L through the communication hole 33 by the upside-down of the container body 201, and the discharge area of the discharge hole 32 formed on the central axis of the plug body 31 is always small. From this range, it is discharged toward the coated surface.

  The discharge plug 30 is movable between the above-described discharge seal position and a dischargeable position. The discharge seal position is not a single fixed point but a concept including all points in a certain range other than the discharge possible position. Note that the dischargeable position may not 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 tubular member 10, has a plug body portion 41 having a generally skirted shape, and the discharge plug 30. It is connected to the discharge plug 30 so that it can be moved up and down in conjunction with the above-mentioned pulling / pushing movement.

  The metering plug 40 moves away from the partition wall 22 of the inner plug 20 by moving in conjunction with the lifting of the discharge plug 30, and forms an inflow path R of the contents between the partition wall 22. The weighing position is set so that an object can be supplied from the supply hole 23 of the partition wall 22 to the measurement space 13.

  On the other hand, the measuring plug 40 is set to a measuring seal position that is close to the partition wall 22 of the inner plug 20 by the movement interlocked with the pushing of the discharge plug 30 and disables the supply of the contents from the supply hole 23 of the partition wall 22. Is done.

  At this time, the inner plug 20 is formed with the fitting seal portion 27 around the supply hole 23 formed in the partition wall 22 as described above, and the measuring plug 40 set at the measuring seal position is The tip of the skirt-like seal portion 42 suspended from the outer peripheral portion of the top surface portion 41A of the plug main body portion 41 is liquid-tightly fitted over the entire inner periphery of the fitting seal portion 27, and the partition The supply of the contents from the supply hole 23 of the wall 22 is disabled.

  As shown in FIG. 14A, the measuring plug 40 has a guide cylinder 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 41. Prepare vertically. The measuring plug 40 is configured to be movable up and down by loosely inserting a guide cylinder 43 around the small diameter guide portion 28B of the guide post 28 included in the inner plug 20, and to make the inner surface of the guide cylinder 43 follow the outer surface of the small diameter guide portion 28B. Thus, the vertical movement of the guide tube 43 is guided to the measuring seal position, and the tip end surface of the guide cylinder 43 is brought into contact with the annular step surface 28C of the inner plug 20 to restrict the movement limit (FIG. 3).

  The metering plug 40 includes an engaging portion 44 that protrudes upward from the central portion of the top surface portion 41A of the plug main body portion 41. The engaging portion 44 includes 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.

  As shown in FIGS. 3 to 7, the spring portion 50 is interposed between the discharge plug 30 and the metering plug 40 inside the tubular member 10. The discharge plug 30, the metering plug 40, and the spring portion 50 are arranged in series along the axial direction of the cylindrical portion 11 in the cylindrical 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 an end portion of the plug main body 31 near the measuring plug 40. The spring portion 50 is a plastic molded body such as polypropylene integrally formed with the discharge plug 30, and an annular portion 51 having substantially the same outer diameter as the outer peripheral surface of the plug main body portion 31 of the discharge plug 30 is connected to the plug 50. The main body 31 is provided with a plurality of spring pieces 52 which are provided at the end near the measuring plug 40 and which hang in the axial direction of the plug main body 31 from a plurality of positions spaced in the circumferential direction of the annular portion 51. Each spring piece 52 has a vertical piece 52A extending downward along the outer peripheral surface of the plug main body 31 in the discharge plug 30, and a horizontal extending from the lower end of the vertical piece 52A toward the radial center of the plug main body 31. The vertical piece portion 52A and the horizontal piece portion 52B are L-shaped.

  The vertical piece 52A and the horizontal piece 52B forming each spring piece 52 of the spring part 50 can surround the bulging part 44B constituting the engaging part 44 of the measuring plug 40 from the outside and can be prevented from coming off. Hug to. Each spring piece 52 receives the pushing force of the discharge plug 30 that is pushed into the inside of the tubular portion 11 of the tubular member 10 in a state where the measuring plug 40 is set at the measurement seal position. The piece 52B is brought into contact with the upper surface of the top surface 41A of the plug main body 41 of the measuring plug 40 so that the plug main body 41 can be pressed in the axial direction, and the vertical piece 52A is compressed and elastically deformed. .

  At this time, each spring piece 52 of the spring portion 50 provided at the end portion of the plug main body portion 31 in the discharge plug 30 can be elastically deformed as described above in a state where the measurement plug 40 is set at the measurement seal position. Therefore, as shown in FIG. 6, there is a vertical piece between the lower surface of the end portion of the stopper main body 31 (the surface on the container main body 201 side) and the upper surface of the bulging portion 44B of the engaging portion 44 of the measuring stopper 40. It is necessary to secure a clearance δ for the compression of 52A.

  The discharge container 200 has a cap (not shown) that is detachably attached to the container body 201. When the cap is attached to the container main body 201, the tip protruding portion 30 </ b> P of the discharge stopper 30 protruding from the cylindrical portion 11 to the outside of the cylindrical member 10 in the discharge tool 10 attached to the container main body 201 ( 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. Thereafter, the cap is detached from the container main body 201 and the discharge tool 100 and removed away from the tip protrusion 30P of the discharge plug 30.

  Therefore, according to the discharge tool 100, when the discharge plug 30 is pulled up, the discharge plug 30 is set at the discharge seal position, and the metering plug 40 can be set at the measurable position by receiving the pulling force of the discharge plug 30. As a result, the contents of the container main body 201 can be supplied to the measuring space 13 inside the cylindrical portion 11 of the cylindrical member 10 by the inverted body of the container main body 201, and a certain amount of content can be measured. The On the other hand, when the discharge plug 30 is pushed, the measuring plug 40 receives the pushing force of the discharge plug 30 and is set to the measurement seal position, while each spring piece 52 of the spring portion 50 receiving the pushing force of the discharge plug 30 By bending and setting the discharge plug 30 to a dischargeable position, the contents measured in the measurement space 13 inside the cylindrical portion 11 of the cylindrical member 10 can be discharged from the discharge hole 32 of the discharge plug 30. To be.

  However, in the discharge tool 100, when the discharge plug 30 is pushed, the measurement plug 40 receives the push force of the discharge plug 30 and is set to the measurement seal position, and then the push-in force of the discharge plug 30 is further increased. Each spring piece 52 of the received spring portion 50 is bent and the discharge plug 30 is set to a dischargeable position, so that the contents measured in the measurement space 13 inside the tubular portion 11 of the tubular member 10 are measured. Discharge is enabled.

  At this time, the spring force of each spring piece 52 of the spring portion 50 is larger than the fitting force with which the metering plug 40 is set at the metering seal position and the plug body portion 41 is fitted to the fitting seal portion 27 of the inner plug 20. It is set to be large. When the spring force is smaller than the fitting force, the discharge seal by the discharge plug 30 is opened while the measurement seal by the measurement plug 40 is incomplete, and the measurement seal cannot be completely achieved.

  That is, the discharge tool 100 constituting the discharge container 200 has the discharge stopper 30 between the maximum pulling stroke end C in the meterable state (FIG. 4) and the maximum pushing stroke end E in the discharge execution state (FIG. 7). It is made movable and performs a metering discharge operation as follows.

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

  At this time, the metering plug 40 is set at a metering seal position where the skirt-shaped seal portion 42 of the plug main body portion 41 is liquid-tightly fitted to the fitting seal portion 27 of the inner plug 20 (FIG. 3). The contents cannot flow into the measuring space 13 of the cylindrical member 10 from the supply hole 23 of the partition wall 22.

(2) Weighable state (Fig. 4)
In conjunction with the removal of the cap (not shown) of the discharge container 200 from the container body 201, the end surface 31P of the discharge plug 30 is lifted from the standby position B of (1) above by a certain pulling stroke S0. When the maximum pulling stroke end C is set (FIG. 4), the discharge plug 30 is still maintained at the discharge seal position (FIG. 4), and the discharge of the contents from the discharge hole 32 is stopped.

  At this time, the metering plug 40 is based on the fact that each spring piece 52 of the spring portion 50 provided integrally with the discharge plug 30 holds the engaging portion 44 of the measurement plug 40. The tip of the skirt-like seal portion 42 of the metering plug 40 is separated from the fitting seal portion 27 of the inner plug 20 in response to the above-described pulling force and is interlocked with the lifting of the discharge plug 30 (FIG. 4). Is set. The top surface portion 41 </ b> A of the plug main body 41 in the measuring plug 40 has a bulging portion 44 </ b> B constituting the engaging portion 44 of the plug main body 41 with respect to the horizontal piece 52 </ b> B of each spring piece 52 in the spring portion 50. The spring pieces 52 are separated from the horizontal piece portions 52 </ b> B so as to pass through the gap G (FIG. 4) in the axial direction. In the discharge tool 100, G = 0 may be sufficient.

  As a result, the metering plug 40 is configured such that the skirt-shaped seal portion 42 of the plug main body portion 41 is separated from the fitting seal portion 27 of the inner plug 20 and forms an inflow path R of the contents between the inner plug 20 and the container. The contents of the main body 201 can be supplied from the supply hole 23 of the partition wall 22 to the measuring space 13 of the tubular member 10. However, the supply of the above-described contents to the measurement space 13 of the cylindrical member 10 is not executed unless the container body 201 is overturned.

(3) Measurement execution state (Fig. 5)
The container main body 201 set in the state (2) in which measurement is possible is inverted (FIG. 5). Thereby, the contents of the container main body 201 pass through the supply hole 23 of the partition wall 22, the inflow path R (arrow in FIG. 5) between the inner plug 20 and the measuring plug 40, and the cylindrical portion of the cylindrical member 10. 11 is supplied to the weighing space 13 inside. At this time, the discharge plug 30 is maintained at the discharge seal position.

  The measuring plug 40 is lowered in the measuring space 13 by the inversion of the container main body 201 and the inflow of contents into the measuring space 13, and the top surface portion 41A of the plug main body portion 41 is moved to each spring piece in the above (2). The gap G for the play that has occurred with respect to the horizontal piece 52B of 52 is eliminated.

(4) Measurement complete state (Fig. 6)
In the discharge tool 100 in which the contents are supplied to the measurement space 13 inside the cylindrical portion 11 of the cylindrical member 10 in the above (3), the discharge plug 30 that protrudes from the opening 12 of the cylindrical portion 11 to the outside. The end surface 31P of the plug main body 31 is pressed against the surface to be coated F such as the scalp. By this pressing external force, the end face 31P of the discharge plug 30 is pushed in by the first pushing stroke S1 from the maximum pulling stroke end C in (2) and (3) above and set to the stroke intermediate point D (see 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 portion 31 is liquid-tightly fitted to the inner peripheral surface of the opening 12 in the cylindrical portion 11 of the cylindrical member 10. Is done. The metering plug 40 receives the pushing force of the first pushing stroke S1 of the discharge plug 30 and interlocks with the pushing of the discharge plug 30, and the skirt-shaped seal portion 42 of the plug main body portion 41 is connected to the inner plug 20. The setting is changed to the measurement seal position where the fitting seal portion 27 is liquid-tightly fitted (FIG. 6). The pushing stroke of the discharge plug 30 is such that the distal end surface of the guide cylinder 43 of the measuring plug 40 abuts on the annular step surface 28C of the inner plug 20 as described above, and the measuring plug 40 is biased to its movement limit. At the same time, the stroke is stopped at the stroke intermediate point D.

  This makes it impossible to supply the contents of the container main body 201 from the supply hole 23 of the inner plug 22 to the measuring space 13 of the tubular member 10, and the measurement of a certain amount of the contents into the measuring space 13 is completed. To do.

  At this time, the discharge plug 30 is located at the discharge seal position, and the content that has been weighed into the measurement space 13 is not unexpectedly discharged from the discharge hole 32 of the discharge plug 30.

(5) Discharge execution state (Fig. 7)
In the discharge tool 100 that has been weighed in (4) above, when the end surface 31P of the plug body 31 of the discharge plug 30 is further pressed against the surface to be coated F such as the scalp, the additional external force of the discharge plug 30 The end face 31P is pushed by the second pushing stroke S2 from the stroke intermediate point D in the above (4), and 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). When set to a level or a level slightly protruding from the end surface A (FIG. 7), each spring piece 52 of the spring portion 50 that receives a further pushing force of the discharge plug 30 bends. The discharge plug 30 is capable of discharging to open the discharge path L so that the inner annular seal portion 34 of the plug main body 31 can discharge the contents measured in the measurement space 13 to the discharge hole 32 side. The position is changed (FIG. 7).

  As a result, the content that has been weighed into the measurement 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 applied to the application surface F such as the scalp.

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

(6) Discharge interruption state (same state as the measurement completion state in FIG. 6)
In the discharge tool 100 that is being measured in the above (5), when the end surface 31P of the plug body 31 of the discharge plug 30 is separated from the application surface F such as the scalp, each spring piece 52 of the spring portion 50 is pressed against the external force. The restoring force of bending due to disappearance is exerted on the discharge plug 30. Upon receiving this restoring force, the discharge plug 30 is pushed out from the maximum push stroke end E by the second push stroke S2 and returned to the stroke intermediate point D in (4) or in the vicinity thereof, and the discharge seal 30 The position is changed (FIG. 6). In addition, when the spring portion 50 integrated with the discharge plug 30 receiving the restoring force is elastically moved from the measuring plug 40 in the axial direction by the restoring force, the horizontal piece portion of each spring piece 52 in the above (2). A gap G in the axial direction generated between 52B and the top surface portion 41A of the plug main body 41 of the metering plug 40 can be formed again.

  Thereby, 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 measured in the measurement space 13 can be dispensed from the discharge hole 32.

Therefore, according to this embodiment, there exist the following effects.
(a) The discharge tool 100 has a spring portion 50 interposed between the discharge plug 30 and the measurement plug 40 inside the tubular member 10, and the discharge plug 30, the measurement plug 40 and the spring portion 50. Are arranged in series along the axial direction of the cylindrical portion 11 of the cylindrical member 10. Accordingly, the discharge plug 30, the metering plug 40, and the spring portion 50 facilitate the reduction of the diameter of the cylindrical portion 11 in the design of the cylindrical member 10 inside the cylindrical portion 11 of the cylindrical member 10, and Miniaturization can be achieved.

  (b) The discharge tool 100 is a spring that receives a further pressing force of the discharge plug 30 after the measurement plug 40 receives the pressing force of the discharge plug 30 and is set to the measurement seal position by the pressing of the discharge plug 30. When the portion 50 is bent and the discharge plug 30 is set to a dischargeable position, the contents measured in the tubular portion 11 of the tubular member 10 can be discharged. That is, there is no possibility that the discharge plug 30 is set to the dischargeable position before the measurement plug 40 is completely set to the measurement seal position. Therefore, when a certain amount of content is supplied to the measuring space 13 of the cylindrical member 10, the discharge plug 30 opens and the measured content is discharged even though the measuring plug 40 is not closed yet. A certain amount of contents can be weighed correctly. Further, the content of a certain amount or more is not supplied to the measuring space 13 of the cylindrical member 10, and there is no possibility that the content is excessively used.

  (c) In the discharge tool 100, the spring force of the spring portion 50 is set larger than the fitting force with which the metering plug 40 fits the plug body portion 41 into the fitting seal portion 27 of the inner plug 20. As a result, the plug body portion 41 of the metering plug 40 is first fitted into the fitting seal portion 27 of the inner plug 20 and is set to the metering seal position by pushing the discharge plug 30 first. Then, when the further pushing force of the discharge plug 30 exceeds the spring force of the spring part 50, the spring part 50 will bend and the discharge plug 30 will be set to a dischargeable position. As a result, it is possible to ensure the metering and discharging operation (b) described above by the discharging tool 100.

  (d) In the discharge tool 100, the discharge plug 30 is movable between the maximum pulling stroke end C and the maximum pushing stroke end E. When the discharge plug 30 is at the maximum pulling stroke end C, the discharge plug 30 is set at the discharge seal position, the measuring plug 40 is set at the measurement possible position, and the discharge plug 30 is moved from the maximum pulling stroke end C by an external force. When the stroke is pushed by the first pushing stroke and set to the stroke intermediate point 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 and receives the measurement seal position. When the discharge plug 30 is pushed by the second push stroke from the stroke intermediate point D by the further external force and set to the maximum push stroke end E, the push force of the discharge plug 30 is further increased. The spring 50 received is bent and the discharge plug 30 is set to the dischargeable position, the measurement plug 40 is still maintained at the measurement seal position, and the discharge plug 30 is turned off. When subjected to the restoring force of the deflection of the spring portion 50 by the discharge plug 30 is caused to return from the maximum push stroke end E to the stroke midpoint D, the discharge plug 30 is set to discharge the sealing position. As a result, it is possible to ensure the metering and discharging operation (b) described above by the discharging tool 100.

  (e) The discharge tool 100 is integrally provided with a spring portion 50 composed of a plurality of spring pieces 52 that hang down from a plurality of positions in the peripheral direction of the end portion of the plug main body 31 near the measuring plug 40. 52 is the axial direction of the cylindrical part 11 in the cylindrical member 10, and holds the engaging part 44 of the measuring plug 40 so as not to be detached, and can press the plug main body 41 of the measuring plug 40 in the axial direction. To. Thereby, the spring part 50 of the above-mentioned (a) can be provided easily.

  (f) A cap that is detachably attached to the container body 201 is provided. When the discharge tool 100 is used, the discharge plug 30 can be pulled up 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, You can start using it.

  In the discharge tool of the present invention, the discharge tool may not have the discharge hole 32 and the communication hole 33 formed in the discharge plug 31 and may not include the outer annular seal portion 35 on the outer peripheral surface of the plug body 31. At this time, in the discharge device 100 in the discharge execution state described above (FIG. 7), the contents inside the tubular portion 11 of the tubular member 10 form an annular shape around the outer periphery of the plug body portion 31 via the discharge path L. It is discharged directly to the outside world in a discharge form.
