Description

  The present invention is capable of constituting a quantitative dispensing container by being mounted on a container body, and capable of dispensing a liquid after accurately measuring a predetermined amount of liquid from the liquid filled in the container body. About.

  Various types of quantitative dispensing containers have been proposed for measuring a predetermined amount from a liquid such as a hair-restoring agent filled therein and allowing only a predetermined amount of liquid to be dispensed.

  For example, Patent Document 1 below discloses the following quantitative dispensing container (for example, see FIG. 1 and Paragraphs 0012 to 0014 of Document 1). That is, if the liquid is filled up in the measuring chamber A side space by reversing the upside-down state from the upright state to the inverted state, and then returning to the upright state, the excess liquid can be obtained. The liquid flows down to the housing 8 side and is returned, and only a predetermined amount of liquid remains in the measuring chamber A and is measured. In this state, if the operating body 5 is rotated, the switching body 4 and the valve body 6 are rotated and lifted so that the space between the housing 8 side and the measuring chamber A side is interrupted, and then the state is inverted again. In the measurement chamber A, a predetermined amount of liquid can be applied from the extraction port.

  Patent Document 2 discloses the following quantitative dispensing container (see, for example, FIGS. 1 and 2 and paragraph 0014 of the same Document 2). That is, by rotating the measuring liquid storage cylinder 21, the measuring liquid storage cylinder 21 is rotated up from the connecting cylinder 6 to which the measuring liquid storage cylinder 21 is screwed, thereby opening the upper part of the measuring chamber forming short cylinder 9. In this state, the liquid is allowed to flow back into the measuring chamber 12 side space by reversing the entire body from the upright state to the inverted state, and then returned to the upright state. Then, only a predetermined amount of liquid remains in the measuring chamber 12 and is weighed. In this state, the measuring liquid storage cylinder 21 is rotated in the direction opposite to the above to cause the measuring liquid storage cylinder 21 to be rotated and lowered, so that the upper part of the measuring chamber forming short cylinder 9 is blocked by the plug body 35. To do. Then, it is disclosed that it is used again upside down in an inverted state.

  Further, Patent Document 3 discloses the following quantitative dispensing container (for example, FIGS. 1 and 3 to 5 in the document 3). That is, if the liquid filled in the container body 2 is turned upside down from the upright state to the inverted state, and the liquid is introduced into the space on the side of the measuring chamber B through the liquid introduction hole 7, and then returned to the upright state, Excess liquid flows down to the container body 2 and returns to the container body 2, and only a predetermined amount of liquid remains in the measuring chamber B and is weighed. In this state, if the liquid introduction hole 7 is closed by rotating the movable part E at a fixed position and being rotated together with the rotating cylinder 17, then if the liquid is inverted again, a predetermined amount in the measuring chamber A is obtained. It is disclosed that a liquid can be applied from an extraction port.

  However, the conventional quantitative dispensing device that constitutes the quantitative dispensing container has various inconveniences in addition to taking time and effort for the user to perform before dispensing the measured liquid.

  That is, in order to dispense and use the liquid in an inverted state, before measuring the predetermined amount of liquid to be used at one time, the liquid is changed from the upright state to the inverted state, and then again. The operation of returning to the upright state is required. For this reason, it takes time to perform the weighing operation. Moreover, if the operation for returning to the upright state is performed, there is a risk that the liquid level stored in the weighing chamber will be shaken and flowed down. In particular, since the liquid is stored in a free liquid level state in the measurement chamber, unless the operation for shutting off the measurement chamber side space from the container body side is completed, it must be handled with the utmost care. Similarly, the liquid in the measuring chamber easily flows down. For this reason, there is an inconvenience that there is uncertainty about the accuracy of the measuring function itself that measures a predetermined amount of liquid.

  Moreover, even if the space on the container body side and the space on the measurement chamber side filled with liquid are shut off from each other after weighing, the blocking method is from one space side to the other space side. If a method of closing the opening by means such as inserting a liquid is used, fluctuations in internal pressure occur in the space on the measuring chamber side, and liquid leaks out at the time of use due to liquid leakage or use due to fluctuations in the internal pressure. There is a risk of inconvenience. In particular, if the liquid is volatile, it volatilizes from the free liquid level of the liquid contained in the measuring chamber to the space on the measuring chamber side, causing a larger internal pressure fluctuation, and increasing the degree of inconvenience described above. It will end up.

  In order to cancel such an internal pressure fluctuation, in Patent Document 3, the air passage 11 is formed in the rod plug 6 attached to the mouth neck portion 3 of the nozzle, and the state shifts between the upright state and the inverted state. It has been proposed that a valve body 12 for connecting the inside and outside is sometimes fitted to the air passage 11 (see FIG. 1 of Patent Document 3 and paragraph 0021). However, not only the number of parts is increased but also the structure is complicated, which may cause malfunction.

  Further, during storage that is not in use, it is required to improve the sealing performance by preventing liquid from flowing from the container main body side into the measuring chamber side space in any state such as lying down.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a quantitative dispensing device that can eliminate the above disadvantages. In other words, it eliminates the trouble of use operation of weighing and dispensing the liquid after weighing, and maintains a reliable storage state without risk of liquid leakage while maintaining accurate weighing and easy and reliable use. To provide a dispensing device.

  In the present invention, the following technical means have been taken for a quantitative dispensing device used by being mounted on a container body for containing a liquid. That is, it has a cylindrical body part having a communication hole formed at the tip, and can be attached to the mouth part of the container body, and when attached, the mouth member that communicates with the inside of the container body, A slider that is screwed into the mouth member in a state of being externally inserted into the cylindrical body and can be moved forward and backward in the approaching / separating direction with respect to the communication hole by a rotation operation, a nozzle hole that can be opened and closed at the tip, and the nozzle And a nozzle cover having a measuring chamber defined in a space facing the hole and coupled to the mouth member so as to be rotatable at a fixed position. The slider is engaged with the nozzle cover so as to be able to transmit a rotational force, and is rotated by receiving the rotational force transmitted from the nozzle cover, thereby closing the communication hole so as to close it. And a forward movement position that opens the communication hole, and a space that faces the nozzle hole in the backward position is partitioned into a predetermined volume to be measured and partitioned. (Claim 1).

  In the case of the present invention, when the quantitative dispensing device is attached to the inside of the container main body filled with a liquid, a quantitative dispensing container is obtained. When the nozzle cover is rotated in a predetermined rotation direction, the rotational operation force is transmitted from the nozzle cover to the slider, and the slider is rotated. By the rotation operation of the slider, the slider moves from the retracted position to the advanced position, and the communication hole is opened. Thereby, it will be in the state which the measurement chamber and the inside of a container main body communicated through the inside of a mouth part member. Therefore, when the whole is converted from the upright state to the inverted state, the liquid in the container body flows into the measuring chamber through the communication hole and fills up. Next, if the nozzle cover is rotated in the direction opposite to the rotation direction, the slider is also rotated in the reverse rotation direction synchronously, the slider returns from the forward position to the reverse position, and the communication hole is converted to a closed state. Is done. As a result, since a predetermined amount of liquid corresponding to the volume of the measuring chamber is separated and accommodated in the measuring chamber, if the nozzle hole is switched to open, the predetermined amount of liquid measured in a full state in the measuring chamber can be dispensed. It becomes possible. According to the present invention described above, the weighing operation is completed simply by rotating in the reverse rotation direction in the inverted state after the rotating operation in the upright state, and the dispensing operation can be performed as it is. . For this reason, as before, after changing from the upright state to the upright state, measuring from the upside down state to the upright state, and again, the dispensing operation from the upright state to the inverted state is performed twice. Can save labor. And even if it returns to an upright state after use, since the communicating hole has already been returned to the closed state, the liquid in the container main body can be maintained in a sealed state and stored as it is.

  In the quantitative dispensing device of the present invention, the communicating hole of the cylindrical body portion is opened at the distal end surface orthogonal to the approaching / separating direction, and the opposing surface as the slider is opposed to the distal end surface of the cylindrical body portion in the approaching / separating direction. In addition, at the retracted position, the opposing surface shields the tip end surface of the cylindrical body portion so that the communication hole is closed (Claim 2). By doing so, when the slider is in the retracted position, the communication hole is closed by the opposing surface of the slider shielding the tip end surface of the cylindrical body portion where the communication hole is formed. That is, the communication hole is closed by contact between the opposing surfaces (the tip surface of the cylindrical body portion and the opposing surface of the slider) perpendicular to the approaching / separating direction that is the advancing / retreating direction of the slider. For this reason, it becomes possible to close a communicating hole more reliably and can improve sealing performance.

  Further, in this case, the slider is formed in a cylindrical shape having a tip portion, and the opposed surface is constituted by the bottom surface in the tip portion, and the portion that does not overlap with the communication hole when projected in the approaching / separating direction with respect to the bottom surface. A through-hole can be formed in the (Claim 3). By doing so, when the slider is in the retracted position and its opposing surface shields the tip end surface of the cylindrical body portion and the communication hole is closed, the slider-side through hole is reliably blocked from the communication hole. It becomes possible to be in the state. On the other hand, when the slider is in the forward movement position and its facing surface is separated from the tip surface of the cylindrical body and the communication hole is opened, the slider-side through hole is converted into a state where it is reliably communicated with the communication hole. Is possible.

  In the quantitative dispensing device of the present invention, the rotational movement amount of the slider is set between the backward position and the forward position between the nozzle cover and the mouth member or between the slider and the mouth member. It is possible to provide a stopper for regulating so as to correspond to the amount of forward and backward movement. In this way, the slider can be moved forward and backward to the retreat position and forward position by simply rotating the nozzle cover to the position regulated by the stopper without having to adjust the amount of rotation of the nozzle cover. It becomes possible to make it.

  In the quantitative dispensing device of the present invention, the valve is further protruded from one or both of the valve body that closes the nozzle hole from the measuring chamber side and the slider or the valve body, and comes into contact when the slider is in the forward position. And a convex portion for preventing the body from retreating toward the measuring chamber. In this way, when the slider is rotated and moved to the forward position for measurement, the communication hole is opened and the measurement chamber side, the mouth member and the container body side are in communication with each other. At the same time, the convex part comes into contact with the valve body, and the convex part prevents the valve body from moving backward. For this reason, the nozzle hole is surely locked in the closed state. For example, even if the valve body is touched during an operation such as converting the container body to an inverted state, the valve body is retracted. Thus, the conversion operation to the inverted state can be performed in a state where the occurrence of inconvenience such as liquid leakage from the measuring chamber is reliably avoided.

  The quantitative dispensing device of the present invention further includes a cap that is screwed to the mouth member so as to cover the nozzle cover, and the cap is engaged with the nozzle cover so that rotational force can be transmitted. Engage with the nozzle cover and slider so that the slider is set to the retracted position in the closed cap state where it is screwed and covers the nozzle cover, while the slider is moved to the forward position by rotating from the closed cap state to the opening direction. As described above, the rotational operation amount and the forward / backward movement amount of the slider can be associated with each other (claim 6). In this way, if the cap is rotated in the opening direction from the closed cap state, the rotational force is transmitted to the slider via the nozzle cover, and the slider can be converted into the forward position. On the contrary, if the cap is put on the nozzle cover and rotated in the reverse direction, the cap reaches a closed cap state in which the nozzle cover is covered, and the slider can be moved to the retracted position. From the above, when in the closed cap state, the slider is positioned in the retracted position and the communication hole is closed, so that it can be reliably maintained in a storage state free from liquid leakage, and can be rotated from the closed cap state to the opening direction. For example, the position of the slider is changed to the forward position, the communication hole is opened, and subsequent weighing is possible.Furthermore, if the cap is put on and closed after pouring, the slider returns to the retracted position and the communication hole is opened. Can be closed.

  As described above, according to the quantitative dispensing device of the present invention, if the quantitative dispensing device of the present invention is attached to the inside of the container body filled with liquid, the quantitative dispensing container is configured immediately. be able to. When the nozzle cover is rotated in a predetermined rotation direction, the rotational operating force is transmitted from the nozzle cover to the slider, and the slider can be rotated. By this rotation, the slider is moved from the retracted position to the advanced position. Thus, the communication hole can be opened. Thereby, it can be set as the state which the measurement chamber and the inside of a container main body communicated through the inside of a mouth part member. Therefore, when the whole is converted from the upright state to the inverted state, the liquid in the container body flows into the measuring chamber through the communication hole and is filled, and then the nozzle cover is rotated in the direction opposite to the rotation direction. Thus, the slider is synchronized and rotated in the reverse direction. As a result, the slider returns from the forward position to the backward position, and the communication hole is converted into a closed state, so that a predetermined amount of liquid corresponding to the volume of the measuring chamber can be separated and accommodated in the measuring chamber. If the nozzle hole is switched to open, a predetermined amount of liquid measured in a full state can be dispensed. According to the present invention described above, the weighing operation can be completed simply by rotating in the reverse rotation direction in the inverted state after the rotating operation, and the pouring operation can be performed as it is. For this reason, as before, after changing from the upright state to the upright state, measuring from the upside down state to the upright state, and again, the dispensing operation from the upright state to the inverted state is performed twice. Labor can be saved. In addition, even if it is returned to the upright state after use, the communication hole has already been returned to the closed state, so that the liquid in the container body can be maintained in a sealed state. Without having to do so.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 and 2 show a quantitative dispensing container equipped with a quantitative dispensing device 1 according to one embodiment of the present invention. When not in use, the fixed-volume dispensing container is stored with a liquid (for example, a liquid agent such as a hair growth agent) filled inside, and when in use, only a certain amount of liquid measured from the liquid inside is dispensed (applied). It ’s what you get. And if this fixed quantity dispensing container is inverted once from the upright state, it can be weighed and poured out as it is. This makes it possible to measure twice by changing from an upright state to an upright state, returning to an upright state from the upright state, and dispensing again after making it upside down again. This makes it possible to easily weigh and dispense without any special operation. There is no limit to the liquid filled in the inside, and even in the case of a highly volatile liquid such as a hair restorer, while maintaining a reliable storage state that does not cause any liquid leakage without causing any inconvenience. Therefore, accurate weighing and easy and reliable dispensing can be achieved. In the following description, the state shown in FIG. 1 is referred to as an upright state, and the state reversed upside down is referred to as an inverted state. The axis X is the central axis of the quantitative dispensing device, and the direction of the axis X is the approaching / separating direction in which a slider 4 (described later) moves forward and backward. In the upright state, the axis X extends in the up-down direction, and “up / down”, which is an advancing / retreating movement in the direction of the axis X, means moving up along the axis X in FIG. Means moving downward as well.

  The fixed volume dispensing container includes a container body 2 filled with the liquid Q, a mouth member 3 coupled to the mouth portion 21 of the container body 2 so as not to move in the vertical direction (axis X direction), and the mouth portion. A cylindrical slider 4 coupled to the member 3 so as to be movable up and down by screwing (movable forward and backward in the axis X direction), and coupled to the mouth member 3 so as to be rotatable at a fixed position in the vertical direction. Nozzle cover 5 engaged so as to be able to transmit a rotational force for raising and lowering to 4, and mounted in the upper part of nozzle cover 5 for opening and closing nozzle hole 50, and nozzles by upward biasing force A spring valve 6 that maintains the hole 50 in a closed state, and a cap 7 that is detachably coupled to the mouth member 3 by screwing and that is associated with the nozzle cover 5 so as to be able to transmit a rotational operation force. Configured. In the present embodiment, the above-mentioned mouth member 3, slider 4, nozzle cover 5, spring valve 6 and cap 7 constitute the quantitative dispensing device 1.

  As will be apparent from the following detailed description, the quantitative dispensing device 1 has a slider 4 in a state where the inner peripheral side is sealed by the mouth member 3 and the outer peripheral side is sealed by the nozzle cover 5. By moving up and down along X, communication between the mouth member 3 (the space in the container main body 2) and the upper part of the nozzle cover 5 (the space in the measuring chamber 54 described later) is communicated / not communicated. Each state can be switched to each other. In addition, the lifting / lowering operation of the slider 4 transmits the rotational operation force for the cap 7 to the slider 4 via the nozzle cover 5, or the rotational operation force for the nozzle cover 5 is applied to the slider 4 without the cap 7. It is configured to be possible by transmitting. In addition, all the above components can be formed by synthetic resin molding, and the container body 2 can also be formed by a glass bottle or the like.

  The mouth portion member 3 (see also FIG. 3) extends downwardly on the annular plate portion 30 that can contact the opening end surface of the mouth portion 21 of the container body 2 and on the same axis as the axis X from the annular plate portion 30. A middle leg cylinder 31, a lower inner cylinder 32, and a lower outer cylinder 33, and an upper inner cylinder 34 and an upper outer cylinder 35 that extend upward coaxially with the axis X from the annular plate portion 30, respectively. ing.

  When the middle leg tube 31 is press-fitted into the mouth portion 21 from above and the annular plate portion 30 is in contact with the opening end surface of the mouth portion 21, the outer peripheral surface thereof is in pressure contact with the inner peripheral surface of the mouth portion 21. It can be assembled with. Thereby, the joint surface between the container main body 2 and the mouth part member 3 is sealed. Further, the lower inner cylinder 32 is externally fitted to the mouth portion 21 so as to be coupled to the container main body 2 in a state in which the lower inner cylinder 32 cannot move relative to the vertical direction. This unmovable connection is performed by undercut fitting between the inner peripheral surface of the lower inner cylinder 32 and the outer peripheral surface of the mouth portion 21. That is, the lip portion 321 that protrudes from the lower end portion of the lower inner cylinder 32 toward the inner peripheral side protrudes from the outer peripheral surface of the mouth portion 21 toward the outer peripheral side, and has a convex strip 211 formed with a downward stepped surface. Based on the above, they are joined by engaging over each other.

  Further, a screw groove 331 having a predetermined pitch is formed on the outer peripheral surface of the lower outer cylinder 33, and a screw thread 741 described later of the cap 7 (see FIG. 1) is screwed together. When the cap 7 is rotated from the predetermined position about the axis X by a predetermined rotation angle (for example, 90 degrees) by the combination of the screw groove 331 and the screw thread 741, the screw thread 741 of the cap 7 is detached from the screw groove 331. The cap 7 can be detached. Further, the rotation around the axis X is stopped between the inner peripheral surface of the lower outer cylinder 33 and the outer peripheral surface of the mouth portion 21. That is, although detailed illustration is omitted, a flange 212 protruding to the outer peripheral side is formed on the outer peripheral surface of the mouth portion 21, and a part of the circumferential direction is cut out to form a groove that opens up and down, and the lower outer cylinder 33. A vertical rib is formed on the inner peripheral surface of the inner peripheral surface so as to protrude in the vertical direction and extend in the vertical direction. By inserting the vertical rib into the groove from above, the lower outer cylinder 33 and thus the mouth member 3 are formed. Is restricted from rotating in the circumferential direction.

  The upper inner cylinder 34 protrudes upward from the inner peripheral end of the annular plate portion 30, and a shoulder step 340 is formed at a predetermined position on the upper end side of the upper inner cylinder 34, and a top wall portion 341 that constitutes the distal end portion of the upper inner cylinder 34. A communication hole 342 is formed through the position where the axis X passes. In addition, a convex rib ring 343 is formed on the tip surface of the top wall portion 341 so as to surround the communication hole 342 and slightly protrude upward. As will be described later, the slider 4 is in the lowered position (shown in FIGS. 1 and 2). The convex rib ring 343 comes into pressure contact with the valve seat 422 of the slider 4 to more securely seal the blocking state between the communication hole 342 and the through holes 421 and 421. Yes. Further, a bulging portion 344 that protrudes outward is formed on the outer peripheral surface of the upper inner cylinder 34 in the vicinity of the shoulder step portion 340, and the bulging portion 344 is vertically directed with respect to the inner peripheral surface of the moving cylinder 41 of the slider 4. The slider 4 and the mouth portion member 3 are sealed by close contact with each other. The upper inner cylinder 34 constitutes a cylindrical body portion of the mouth portion member 3, and the distal end surface of the top wall portion 341 constitutes a distal end surface orthogonal to the axis X direction (the proximity / separation direction).

  Further, the upper and outer cylinders 35 surround the upper and inner cylinders 34 to form a housing portion for the moving cylinder 41 of the slider 4 therebetween, and the moving cylinder 41 of the slider 4 with respect to the screw groove 351 on the inner peripheral surface of the upper and outer cylinders 35. Screws 411 on the outer peripheral surface of the screw are screwed together. The screw grooves 351 and the screws 411 are formed at a predetermined pitch, and are transmitted in a vertical direction between a descending position and an ascending position, which will be described later, by receiving a rotational force described later and rotating at a predetermined rotational angle (for example, a central angle of 90 degrees). It is set so as to be a predetermined ascent / descent amount (advance / retreat amount) of the range. Then, on the outer peripheral surface of the upper outer cylinder 35, outward vertical ribs 352, 352,... Extending in the up-down direction are formed at respective positions equally divided in the circumferential direction (interval of 90 degrees central angle). When a later-described inward vertical rib 512 of the nozzle cover 5 abuts against the vertical rib 352, the rotation range around the axis X of the nozzle cover 5 is restricted to 90 degrees. An engaging convex portion 353 having a downward engaging surface and projecting outward is formed at the lower end position of the vertical ribs 352, 352,..., And extends outward in the circumferential direction. The nozzle cover 5 is restricted so as not to move in the vertical direction by the direction protrusions getting over and engaging from above.

  The slider 4 (see FIGS. 2 and 4) includes a moving cylinder 41 that is screwed with the inner peripheral surface of the upper outer cylinder 35 of the mouth member 3, a top wall part 42 that covers the upper end of the moving cylinder 41, and a top wall part. The pin-shaped convex part 43 which protrudes upward along the axis | shaft X from the center position of 42 is comprised. The movable cylinder 41 is formed with the screw 411 at the lower portion of the outer peripheral surface thereof, and outwardly extending vertical ribs 412 and 412 for transmitting rotational force are formed at the upper portion of the outer peripheral surface. Further, a shoulder step portion 413 is formed at the upper end side position of the movable cylinder 41 so as to cover the shoulder step portion 340 of the mouth portion 21 from above when the slider 4 is in the lowered position. At least one, in the illustrated example, two through holes 421 and 421 are formed in the top wall portion 42 so as to penetrate the both side positions with the convex portion 43 interposed therebetween.

  Further, a valve seat portion 422 is formed at the bottom portion of the top wall portion 42 except for the through holes 421 and 421. When the slider 4 is in the lowered position (retracted position), the valve seat portion 422 The convex rib ring 343 on the upper surface of the top wall portion 341 of the upper inner cylinder 34 facing each other is pressed against the lower surface (opposing surface), and the communication hole 342 and the through holes 421 and 421 are sealed to be sealed. It is supposed to be. That is, when the slider 4 is in the lowered position, the lower surface of the valve seat portion 422 closes the communication hole 342 so that the through holes 421 and 421 are in the direction of the axis X with the communication hole 342. The position is set so as not to overlap. Here, the valve seat portion 422 is preferably formed of a material different from the material constituting the slider 4 (a material having more flexibility or elasticity than the slider 4) in order to improve the blocking performance. For this purpose, the valve seat part 422 and the slider 4 of the other part are integrally formed by two-color molding using two kinds of different synthetic resins, or the valve seat part 422 formed separately is provided as the slider 4. It can be made to fit in the recessed part formed in this, and it can be made to couple | bond by means, such as a hot melt.

  When the slider 4 is in the raised position (advance position) as described later, the protrusion 43 contacts the lower surface of the disc portion of the valve body 63 of the spring valve 6 (preferably upwardly pressing). Then, even if the shaft portion 62 of the valve body 63 is pushed from the outside with the nozzle hole 50 closed, the metering chamber 54 is maintained in a sealed state so as not to move downward (retracted side). It can be locked more firmly. As shown in FIGS. 1 and 2, a concave portion into which the tip 431 of the convex portion 43 fits can be provided on the lower surface of the disc portion of the valve body 63 when the slider 4 is in the raised position.

  The nozzle cover 5 (see FIGS. 2 and 5) includes a large-diameter cylinder 51 on the lower end side, an intermediate-diameter cylinder 52 that extends upward on the large-diameter cylinder 51 via a step 511, and an upper-diameter cylinder 52. And a nozzle portion 53 that protrudes upward in a bullet shape through a step portion 521. Longitudinal ribs 512 and 512 that protrude inward and extend in the vertical direction are formed on the inner peripheral surface of the large-diameter cylinder 51 (see FIG. 2), and when the nozzle cover 5 rotates about the axis X, the vertical ribs 512 The rotation range of the nozzle cover 5 is restricted to a predetermined range by abutting on the outward vertical ribs 352, 352,.

  The inner circumferential surface of the medium-diameter cylinder 52 (see FIG. 2) has a circumferential width substantially equal to the circumferential width of the vertical rib 412 of the slider 4, so that the vertical rib 412 can be inserted from above. A pair of inward vertical ribs 522 extending in the vertical direction at both positions separated by a width are formed at respective positions 180 degrees apart in the circumferential direction. By inserting the vertical rib 412 of the slider 4 from below into the position sandwiched between the pair of vertical ribs 522 of each set, it is possible to transmit the rotational force around the axis X from the nozzle cover 5 to the slider 4. That is, the rotational force from the nozzle cover 5 is transmitted to the slider 4 through the pair of vertical ribs 522 and the vertical ribs 412 that are in circumferential contact with the pair of vertical ribs 522, whereby the slider 4 is synchronized with the rotation of the nozzle cover 5. The two are linked to each other so as to be rotated.

  On the other hand, on the outer peripheral surface of the medium-diameter cylinder 52 (see FIGS. 2 and 5), a pair of outward longitudinal ribs 523 extending in the vertical direction at both positions spaced apart by a predetermined interval in the circumferential direction, As in the case of the inner circumferential surface, the inner circumferential surface is formed at each position 180 degrees apart. A pair of vertical ribs 523 of each set and a pair of engagement convex portions 751 (described later) of the cap 7 abut on each other in the circumferential direction, so that the rotational operation force with respect to the cap 7 is transmitted to the nozzle cover 5 and the transmitted rotation is transmitted. A force is transmitted from the nozzle cover 5 to the slider 4.

  A seal cylinder portion 524 that extends obliquely inward is formed on the bottom surface of the nozzle portion 53 on the lower surface of the step portion 521 (see FIG. 2). The seal tube portion 524 has a tip portion 525 that is in close contact with the outer peripheral surface of the upper end side of the moving tube 41 of the slider 4, thereby allowing the slider 4 to slide in the vertical direction, while the nozzle portion 53 (nozzle cover The seal between 5) and the slider 4 is performed. With this seal, when the slider 4 is in the lowered position, that is, when the slider 4 is in the lowered position and the through holes 421 and 421 and the communication hole 342 are blocked and are not in communication with each other, The space is defined in a sealed state as a measuring chamber 54 having a predetermined volume to be measured.

  The nozzle portion 53 (see FIG. 2) has an internal space serving as a measuring chamber 54, a nozzle hole 50 communicating with the measuring chamber 54 is formed at the top end, and a spring valve 6 for switching the nozzle hole 50 to open / close is provided. It is housed in the internal space. That is, the spring valve 6 is inserted from the lower end opening of the nozzle cover 5 and is fitted by undercut fitting from the lower side to the inner peripheral surface of the lower side of the measuring chamber 54.

  Here, as shown in FIG. 6, the spring valve 6 is formed in a spiral shape so as to connect the annular pedestal 61 positioned at the lower portion, the valve body 63 positioned at the upper portion, and the valve body 63 and the pedestal 61 to each other. Are provided with a plurality of elastic arm portions 64, 64,. And the convex part 611 bulged outwardly on the outer peripheral surface of the pedestal 61 from the lower side with respect to the convex part formed so as to bulge inwardly on the inner peripheral surface of the lower position of the measuring chamber 54. By getting over and engaging with each other, an undercut fit is made in the nozzle portion 53. The valve body 63 is mainly configured by a disk portion that is in close contact with the seat surface formed by the inner peripheral surface below the nozzle hole 50, and integrally includes a shaft portion 62 that extends upward from the disk portion. As shown in FIG. 2, the valve body 63 is concentrically held with respect to the nozzle hole 50 by inserting the shaft portion 62 from the lower side (measuring chamber 54 side) upward with respect to the nozzle hole 50. It is like that.

  The spring valve 6 receives an elastic biasing force from the elastic arm portions 64, 64,..., So that the tip end portion of the shaft portion 62 of the valve body 63 protrudes upward from the nozzle hole 50, and the valve body 63 moves below the nozzle hole 50. The nozzle hole 50 is maintained in a closed state in a state in which the nozzle hole 50 is pressed and brought into close contact with a seat surface constituted by the inner peripheral surface on the side. One or more (three in the illustrated example) concave grooves 621, 621,... (See also FIG. 6) extending in the vertical direction are formed on the outer peripheral surface of the shaft portion 62. When the tip of the shaft portion 62 protruding from the elastic arm portion 64 is pushed against the urging force of the elastic arm portion 64, the disc portion of the valve body 63 is separated from the seat surface, and the measuring chamber 54 and the outside are connected to each other through the concave grooves 621, 621,. The nozzle holes 50 communicate with each other and are opened.

  If the nozzle hole 50 is closed, the measuring chamber 54 is cut off from the space in the mouth member 3, that is, in the container body 2 when the slider 4 is in the lowered position (see FIG. 2). On the other hand, when the slider 4 is in the raised position as will be described later, the measuring chamber 54 and the space in the container body 2 are in communication with each other.

  Returning to FIG. 1, the cap 7 is formed by combining an outer member 71 and an inner member 72. The outer material 71 has a shape that exhibits the design of the appearance in accordance with the shape of the container body 2, while the inner member 72 has a structure for exerting and enhancing the functionality of the quantitative dispensing container. It is equipped with. That is, the inner member 72 can be screwed into the screw groove 331 of the lower outer cylinder 33 of the mouth member 3 by the lower end flange 73 for coupling with the outer member 71 and the screw thread 741 formed on the inner peripheral surface. A second cylinder part capable of transmitting a rotational operation force to the nozzle cover 5 via each pair of vertical ribs 523 by a first cylinder part 74 and a pair of engaging projections 751 formed on the inner peripheral surface. 75 and a third cylindrical portion 76 that covers and protects the nozzle portion 53 of the nozzle cover 5. The third cylinder portion 76 includes a protective cover portion 761 at the top thereof, and the protective cover portion 761 prevents an unexpected pressing force from acting on the shaft portion 62 from the outside in a state where the shaft portion 62 protrudes from the nozzle hole 50. To protect it. That is, the nozzle hole 50 can be safely maintained in a closed state. As described above, the cap 7 can be formed as a single unit without being divided into the outer member 71 and the inner member 72. However, in order to reduce the weight while satisfying the appearance design and the functionality with respect to the inner nozzle cover 5 and the like, it is particularly advantageous to divide and configure the outer member 71 and the inner member 72. From the viewpoint of

  The transmission of the rotational force of the cap 7, the nozzle cover 5 and the slider 4 will be described with reference to FIG. The cap 7 in the closed cap state (the state shown by the solid line in FIG. 7A; the state shown in FIG. 1) is rotated about the axis X in the opening direction W (for example, counterclockwise) by a rotation operation amount of 90 degrees (opened). When the cap operation is performed, one of the pair of vertical ribs 523 of the middle diameter cylinder 52 of the nozzle cover 5 is connected to one of the pair of engaging protrusions 751 of the second cylinder 75 constituting the cap 7. Is pushed in the opening direction W, whereby the nozzle cover 5 rotates in synchronization. On the other hand, as the nozzle cover 5 is rotated 90 degrees, the vertical rib 412 of the moving cylinder 41 of the slider 4 sandwiched between the pair of vertical ribs 522 and 522 of the medium diameter cylinder 52 is also pushed in the opening direction W. As the cap 7 is rotated, the slider 4 is also rotated by 90 degrees synchronously. For this reason, when the cap 7 is rotated, the slider 4 is also rotated in synchronization with the nozzle cover 5.

  On the other hand, a stopper is provided to ensure that the rotation range of the nozzle cover 5 is regulated to a predetermined center angle (90 degrees in this embodiment). That is, with the synchronous rotation of the nozzle cover 5 based on the rotation operation of the cap 7, the longitudinal ribs 512 and 512 of the large-diameter cylinder 51 (see FIG. 7B) rotate and move in the opening direction W as well. The vertical ribs 512, 512 abut against the vertical ribs 352, 352,. The vertical ribs 352, 352,... Are formed at predetermined positions at intervals of 90 degrees in the circumferential direction, thereby reliably restricting the rotation range of the nozzle cover 5 to 90 degrees. This is for restricting the amount of rotational movement of the slider 4 to a predetermined center angle (90 degrees) so that the up-and-down movement range of the slider 4 is surely between the lowered position and the raised position as will be described later. is there. The combination of the vertical rib 352 and the vertical rib 512 constitutes a stopper. The installation positions of the vertical ribs 352, 352,... Can be set according to the rotational movement amount of the slider 4 for realizing the raising / lowering operation between the lowered position and the raised position. When the angle is set to 120 degrees as in the above, the positions can be set at intervals of 120 degrees in the circumferential direction. The stopper is provided between the slider 4 and the mouth member 3 in place of the combination of the vertical ribs 512 and 352 that abut against each other between the nozzle cover 5 and the mouth member 3. Can do.

  As the slider 4 rotates 90 degrees in the opening direction W, the slider 4 moves along the axis X from the lowered position shown in the left part of FIG. 1, FIG. 2 or FIG. 8 to the raised position shown on the right side of FIG. To rise. By the raising operation of the slider 4, the valve seat 422 of the slider 4 is separated upward from the convex rib ring 343 of the mouth member 3, and the communication hole 342 and the through holes 421 and 421 communicate with each other through the gap space. As a result, the measuring chamber 54 and the inside of the container main body 2 are converted into a state where they are in communication with each other (communication state). In the present embodiment, the slider 4 is set to move up and down between the lowered position and the raised position with a rotation amount of 90 degrees in the opening direction W at the center angle. The amount of rotational movement that realizes the up-and-down movement between the position and the ascending position can be appropriately determined in consideration of the user's operational feeling and the like. For example, it can be set so that the vertical movement between the lowered position and the raised position is realized by rotating the central angle by 120 degrees. Such a change setting can be made by adjusting the screw pitch of the screw fitting between the slider 4 and the mouth member 3.

  Then, as shown in the left part of FIG. 8, if the cap 7 is in the closed cap state in the state where the container body 2 is filled with the liquid Q, the slider 4 is set to the lowered position, and the slider 4 The valve seat portion 422 is in pressure contact with the top wall portion 341 (convex rib ring 343: see FIG. 2) of the mouth member 3, and the communication hole 342 and the through holes 421 and 421 are blocked from each other. (See also FIG. 2). For this reason, the liquid Q is reliably stored and stored in the container body 2 in a sealed state, and the liquid Q flows into the measuring chamber 54 from the container body 2 side even if the whole is overturned. There is no.

  Then, when the cap 7 is opened (rotated in the opening direction W), the rotational operation force is transmitted from the cap 7 to the nozzle cover 5, and at the same time, the rotational operation force is transmitted from the nozzle cover 5 to the slider 4. The slider 4 is rotated by 90 degrees. As a result, the slider 4 rises from the lowered position to the raised position. As a result, as shown in the right part of FIG. 8, the valve seat portion 422 and the top wall portion 341 (convex rib ring 343: see FIG. 2) are separated, and the communication hole 342 and the through holes 421 and 421 communicate with each other. Thus, the measuring chamber 54 can be converted from a non-communication state to a communication state communicating with the inside of the container body 2. Further, by the rise to the raised position, simultaneously with the conversion to the communication state, the convex portion 43 of the slider 4 can come into contact with the valve body 63 of the spring valve 6 to lock the nozzle hole 50 in the closed state. For this reason, even if the shaft portion 62 of the valve body 63 exposed to the outside touches another object or the shaft portion 62 is pushed by mistake, the valve body 63 does not move, and the measuring chamber 54 can be reliably maintained in the closed state. If the cap 7 is rotated 90 degrees in the opening direction W, the cap 7 can be unscrewed and separated from the mouth member 3 (container body 2).

  Thereafter, as shown in FIG. 9, when the whole is changed from the upright state to the inverted state, the liquid Q in the container body 2 flows into the measuring chamber 54 through the communication hole 342 and the through holes 421 and 421 in the communication state. The measuring chamber 54 is filled with the liquid Q (see the left part of FIG. 9). Next, when the nozzle cover 5 is rotated in the closing direction opposite to the opening direction W of the cap 7 (see FIG. 8), the rotational operation force is transmitted from the nozzle cover 5 to the slider 4, and the slider 4 is moved from the raised position. Returning to the lowered position (refer to the center portion of FIG. 9), the communication hole 342 and the through holes 421 and 421 return to a non-communication state where the space is blocked. As a result, the measuring chamber 54 is sealed in a state where the liquid Q is filled therein. That is, a predetermined amount of liquid Q can be accurately measured by reliably separating the amount of liquid Q corresponding to the space volume in the measuring chamber 54. Here, since the liquid to be weighed is stored in the measuring chamber 54 in a full state, even if the liquid is volatile, the internal pressure does not fluctuate due to volatilization. In addition, in the process from the communication state to the non-communication state, the volume in the measurement chamber 54 is not reduced, so that the internal pressure fluctuation is not generated in the liquid in the measurement chamber 54 after the measurement.

  As a result of the slider 4 returning to the lowered position, the locked state of the valve body 63 is released. Therefore, the shaft portion 62 (see the right side portion of FIG. 9) of the valve body 63 is pressed against the affected area (for example, the scalp) H as it is. The elastic arm portions 64, 64,... Of the valve 6 are bent and the valve body 63 is retracted, whereby the nozzle hole 50 is opened through the concave grooves 621, 621,. Therefore, the liquid Q in the measuring chamber 54 is poured into the scalp H through the concave grooves 621, 621,... And can be applied to the scalp, and the inside of the measuring chamber 54 is replaced with external air. To be empty. That is, by pressing the shaft portion 62 against the scalp H or the like, only a fixed amount of liquid Q corresponding to the volume (for example, 5 ml) in the measuring chamber 54 in a non-communication state can be dispensed. At this time, since there is no fluctuation in the internal pressure in the measuring chamber 54 as described above, there is no possibility of causing inconveniences such as liquid leakage due to fluctuations in the internal pressure or liquid jumping out at the time of pouring.

  After use, return the quantitative dispensing container to the upright state, put the cap 7 on, and rotate the cap 7 in the closing direction (in the opposite direction to the opening direction W) (hereinafter also referred to as “closing cap operation”). Thus, the original closed cap state (the state indicated by the solid line in FIG. 7A) is restored. At that time, regardless of the position where the cap 7 is placed from above (the rotational position in the circumferential direction) or the rotational position of the nozzle cover 5 (whether the slider 4 is in the lowered position or the raised position). Regardless of the above, the original closed cap state can be restored by the rotation operation in the closing direction after the cap 7 is put on.

  That is, each of the pair of engaging convex portions 751 formed on the third cylindrical portion 75 of the inner member 72 of the cap 7 extends in a direction in which one engaging convex portion 751b obliquely intersects the tangent line and opens in the opening direction W. Rotational force can be transmitted only to the vertical rib 523, and in the opposite closing direction, it can move over the vertical rib 523 based on the elasticity or flexibility of the material. On the other hand, the other engaging convex portion 751a is constituted by a protrusion protruding radially inward from the inner peripheral surface of the third cylindrical portion 75, and the cap 7 is rotationally moved in the closing direction so that the vertical rib is formed. When it hits 523, the rotational force in the closing direction can be transmitted to the nozzle cover 5. For this reason, even if the cap 7 is covered from any position in the circumferential direction, when the cap 7 is rotated in the closing direction, the other engaging convex portion 751a hits the vertical rib 523 and rotates in the closing direction. Until the force can be transmitted, one of the engaging convex portions 751b moves over the vertical rib 523 and rotates in the closing direction. Then, by rotating the cap 7 in the closing direction, the other engaging projection 751a rotates until it abuts against the vertical rib 523, and after the abutment, the rotational force in the closing direction is transmitted to the nozzle cover 5 so that the slider 4 It is possible to return to the original closed cap state in which is in the lowered position (non-communication state). If it returns to a closed cap state, measurement and pouring will become possible again by the opening cap 7 operation with respect to the cap 7. FIG.

  By the way, if the dispensing of the metered to fixed amount liquid is repeated, the user can determine whether the slider 4 is in a communication state or a non-communication state when the cap is finally used and the closing cap operation is performed. Then there is a possibility of disappearing. However, even if the slider 4 is in any rotational position, that is, whatever the nozzle cover 5 is in the rotational position, as long as the cap 7 is put on and the closing cap operation is performed, the slider 4 as described above. Can be reliably returned to the non-communication state. Thereby, the liquid Q in the container main body 2 can be reliably stored in a sealed state.

  Note that two sets (two pairs) of the pair of vertical ribs 523 and 523 are arranged at intervals of 180 degrees in the circumferential direction. Furthermore, the pair of vertical ribs 523 and 523 can be replaced by one vertical rib that is sandwiched between the pair of engaging convex portions 751a and 751b from both sides in the circumferential direction. When one vertical rib is used, a width can be given in the circumferential direction.

  As shown in FIG. 10, the above-described quantitative dispensing container has the mouth member 3 attached to the container body 2 filled with the liquid Q, and the screw groove 351 in the upper outer cylinder 35 of the mouth member 3 is provided. In contrast, the screw cover 411 of the moving cylinder 41 of the slider 4 is screwed in and screwed together, and the nozzle cover 5 in a state where the shaft portion 62 of the valve body 63 of the spring valve 6 is inserted into the nozzle hole 50 is placed on the upper and outer sides of the mouth member 3. The cylinder 35 is attached to the outer circumferential surface from above a predetermined circumferential position. Finally, the cap 7 is placed on the vertical rib 523 of each set of the medium diameter cylinder 52 of the nozzle cover 5 from above so as to be in a predetermined circumferential direction, and the screw groove 331 of the lower outer cylinder 33 of the mouth member 3 is placed. It is completed by screwing in and screwing it into a closed cap state.

  Alternatively, the quantitative dispensing device can be assembled in advance separately from the container body 2. That is, the screw cover 411 of the moving cylinder 41 of the slider 4 is screwed into the thread groove 351 in the upper and outer cylinders 35 of the mouth member 3 and screwed together, and the nozzle cover 5 in a state where the spring valve 6 is first assembled is fitted to the mouth part. The member 3 is attached to the outer peripheral surface of the upper outer cylinder 35 from above a predetermined circumferential position. Finally, the cap 7 is placed on the vertical rib 523 of each set of the medium diameter cylinder 52 of the nozzle cover 5 from above so as to be in a predetermined circumferential direction, and the screw groove 331 of the lower outer cylinder 33 of the mouth member 3 is placed. And is screwed into a closed cap to complete a quantitative dispensing device. Then, the liquid Q is filled into the container main body 2, and the fixed amount dispensing device 1 in a pre-assembled state is attached to the mouth portion 21 (see FIG. 1) of the container main body 2 after the filling, thereby quantitative dispensing. A quantitative dispensing container as a product comprising the device 1 and the container body 2 can be obtained.

  In the case of a quantitative dispensing container assembled with the above-described quantitative dispensing device, the measuring chamber 54 can be converted from a non-communication state to a communication state by simply removing the cap 7 in the upright state, and with the cap 7 removed. By simply turning the nozzle cover 5 in the inverted state and then rotating the nozzle cover 5 in a reverse direction, it is possible to perform a quantitative dispensing / application operation on the scalp as it is. In other words, compared to the conventional quantitative dispensing container, it was changed from the upright state to the inverted state, returned from the inverted state to the upright state, and once again, it was not possible to perform the dispensing and application operation to the scalp. Therefore, it is not necessary to temporarily return from the inverted state to the upright state, and the operability can be greatly improved. Moreover, since the liquid in the measuring chamber 54 is measured in a state where the liquid is filled inside and does not have a free liquid level, the liquid is swayed compared to the case where the liquid is measured in the state of being worn out and having a free liquid level. Even if it is received, there is no possibility that the amount of liquid in the measuring chamber 54 will change, a predetermined amount can be accurately measured, and the accurate measuring state can be reliably maintained. In particular, when the operation of returning the measuring chamber 54 from the communication state to the non-communication state is performed, it is not necessary to consider the outflow of the liquid, and the handling can be facilitated.

  Further, when not in use, that is, in a state where the cap 7 is put on the container body 2, the through holes 421 and 421 on the weighing chamber 54 side are in a non-communication state blocked from the communication hole 342 on the container body 2 side. Therefore, even if the container is placed in a state such as lying down instead of being in an upright state, the liquid Q accommodated in the container body 2 is maintained in a sealed state, and the occurrence of liquid leakage or the like can be avoided. Moreover, if the cap 7 is in the closed cap state, it can be seen that the sealed state is maintained. On the other hand, if the cap 7 is in the open cap state, the cap 7 is already converted into a meterable state by the open cap operation. Therefore, the user can grasp that a certain amount of the liquid Q is ready to be dispensed / applied simply by looking at the appearance.

<Other embodiments>
The present invention is not limited to the above-described embodiment, but includes various forms. That is, in the said embodiment, since the outer member 71 which comprises a part of cap 7 is formed so that it may be equipped with the shape which exhibits the external appearance design property with the shape of the container main body 2, this Omitted, for example, as shown in FIG. 11 (a), a quantitative dispensing device 1a having a cap 7 'constituted only by the inner member 72 can be obtained. Alternatively, the outer peripheral surface of the inner member 72 itself can be changed to one having a predetermined shape in consideration of design, and thus the cap can be configured only by the inner member. Further, the quantitative dispensing device can be configured by omitting the cap 7 itself. For example, as shown in FIG. 11B, the quantitative dispensing device 1b can be configured without the cap 7. In this case, the conversion of the slider 4 from the lowered position to the raised position is replaced with the cap opening operation of the cap 7 and the nozzle cover 5 itself is gripped and rotated in the opening direction W. Also in this case, instead of automatically raising the slider 4 by opening the cap 7, the slider 4 can be automatically raised by rotating the nozzle cover 5, and the other effects are the same as in the above embodiment. You can get things. When configured without the cap 7, the protective cover 8 for covering the nozzle hole 50 and the shaft portion 62 protruding from the nozzle hole 50 can be detachably fitted to the nozzle cover 5. Moreover, the cap 7 can be comprised only by the outer member 71, and this outer member 71 can be externally fitted to the opening | mouth part member 3 or the container main body 2 so that attachment or detachment is possible.

  In the said embodiment, although the example which comprised the mouth part member 3 and comprised the fixed quantity extraction apparatus was shown, it is not restricted to this, The mouth part member 3 can be abbreviate | omitted and a fixed quantity extraction apparatus can be comprised. For example, by using a dedicated container body in which a portion corresponding to the mouth member 3, in particular, a portion corresponding to the upper inner cylinder 34 and the upper outer cylinder 35 is formed integrally with the mouth portion 21 of the container body 2, the mouth member 3 can be omitted to constitute a quantitative dispensing device. Therefore, in this case, a quantitative dispensing container including such a dedicated container main body and a quantitative dispensing device in which the mouth member 3 is omitted can be obtained.

  In the above-described embodiment, the slider 4 having the convex portion 43 is shown. However, the present invention is not limited to this, and a convex portion that plays the same role as the convex portion 43 is used instead of the convex portion 43. It can be formed integrally with the valve body 63 so as to protrude downward from the disk portion. Or it can replace with the convex part 43 by forming the convex part which protrudes in the opposing direction from both the slider 4 and the valve body 63, respectively. Note that the convex portion 43 or the convex portion can be omitted. If the convex portion 43 is omitted, the function of locking the valve body 63 of the spring valve 6 cannot be provided at the slider ascending position, but all the basic functions and effects as other quantitative dispensing devices are obtained. be able to.

  Furthermore, in the above-described embodiment, the inner peripheral side of the slider 4 is sealed by being in close contact with the bulging portion 344 of the mouth member 3, while the outer peripheral side of the slider 4 is sealed by the seal cylinder portion 524 of the nozzle cover 5. The slider 4 itself is configured to be movable up and down along the axis X in a state where the tip 525 is slidably brought into close contact with the seal slidable portion (the bulging portion 344 or the tip 525). The forming position and the member to be formed (the mouth member 3 or the nozzle cover 5) are not particularly limited, and a forming position and a forming member different from those in the above embodiment can be selected. For example, a seal portion can be formed on the slider 4 side.

  In the above-described embodiment, the configuration example in which the axis X extends in the vertical direction and the slider 4 moves up and down is shown. However, the configuration is not limited thereto, and the configuration is such that the axis X extends in the horizontal direction and the slider moves in the horizontal direction. Can do. For example, both the upper inner cylinder 34 and the upper outer cylinder 35 of the mouth member 3 protrude laterally, and the middle leg cylinder 31, the lower inner cylinder 32, and the lower outer cylinder 33 are formed so as to extend downward. The slider 4, the nozzle cover 5, and the like can be coupled laterally with respect to the inner cylinder and the upper and outer cylinders. Thereby, the thing of the state bent to the side so that L character may be turned upside down can be comprised as a fixed_quantity | quantitative_assay dispensing apparatus with which the opening part 21 opened upwards of the container main body 2 can be comprised. In this case, since the axis X extends in the horizontal direction, the slider 4 moves back and forth in the horizontal direction, so that the retracted position (corresponding to the lowered position in the embodiment) and the advanced position (corresponding to the raised position in the embodiment). ).

  In addition, the communication hole 342 of the mouth member 3 can be provided with a communication cylinder similar to the communication cylinder (16) of the quantitative dispensing container disclosed in, for example, Utility Model Registration No. 2583154. The plurality of ribs can be suspended and held in the circumferential direction connecting the outer peripheral surface of the through cylinder and the inner peripheral surface of the communication hole 342. In this case, the rib can be extended over the entire length in the axial direction of the cylinder, and according to this, the flow of the liquid Q is guided by the rib, and the liquid Q flows out more smoothly into the measuring chamber 54. In addition, since the air in the measuring chamber 54 flows through the through-cylinder into the container body 2, the replacement of the air in the measuring chamber 54 with the liquid Q in the container body 2 is smoother. To be done.

  Further, instead of the spring valve 6, the valve body 63 and the pedestal 61 are constituted by separate members, and an urging means such as a coil spring is provided between the pedestal 61 and the valve body 63, thereby providing the valve body 63. Can be biased to the closed position.
