Description

The present invention relates to a quantitative pouring container that can be poured after accurately measuring a predetermined amount of liquid from a container body filled with liquid.

Various quantitative injection containers have been proposed for measuring a predetermined amount from a liquid such as a hair restorer filled inside and allowing only the measured predetermined amount of liquid to be dispensed.

For example, Patent Document 1 below discloses the following quantitative dispensing container (see, for example, FIG. 1 and paragraphs 0012 to 0014 of the same document 1). That is, if the liquid is turned upside down from the upright state to the inverted state, the liquid filled in the bottle 8 is allowed to flow into the space on the measuring chamber A side to fill it, and then the liquid is returned to the upright state. The liquid flows down to the bottle 8 side and is returned, and only a predetermined amount of liquid remains in the measuring chamber A and is weighed. In this state, if the operating body 5 is rotated to rotate and raise the switching body 4 and the valve body 6 to block the space between the bottle body 8 side and the measuring chamber A side, the switching body 4 and the valve body 6 are put into the inverted state again. , A predetermined amount of liquid in the measuring chamber A can be applied from the extraction port.

Further, Patent Document 2 discloses a fixed-quantity take-out container for powdery or granular cosmetics, seasonings, and other powders rather than liquids (for example, FIG. 1 of the same document 2). See Fig. 2, page 3, column 5, etc.). That is, the slide rod 5 having the measuring member 15 connected to the lower end is inserted into the pipe (annular wall) 3 extending downward from the opening in the container body 1, the lower surface of the measuring member 15 and the container. A spring 17 for urging the slide rod 5 and the measuring member 15 upward is interposed between the inner bottom of the main body 1 and a protrusion 24 is formed downward from the center position of the cap 21. Disclosed that the cap 7 is screwed into the opening neck 2 of the container body 1 in a state where the slide rod and the measuring member are pushed downward against the spring 17 by abutting the upper end of the slide rod 5. There is. Then, when the cap 7 is removed, the slide rod 5 and the measuring member 15 jump upward due to the urging force of the spring 17, and the upper end edge of the measuring member 15 comes into contact with the lower end edge of the pipe 3, thereby reversing the whole. Then, it is said that the powder and granules weighed in the measuring member 15 can be taken out.

However, the fixed-quantity dispensing container constituting the conventional fixed-quantity dispensing container has various inconveniences, in addition to the troublesome operation that the user should perform before weighing and pouring the measured liquid.

That is, before using the liquid in an inverted state by pouring out the liquid, in order to measure a 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. , It is necessary to return to the upright state. Therefore, the weighing operation is troublesome. Moreover, if the operation of returning to the upright state is performed in a hurry, the liquid level contained in the measuring chamber in the worn state may shake and flow down. In particular, since the liquid is stored in the measuring chamber with a free liquid level, it must be handled with the utmost care until the operation for blocking the space on the measuring chamber side from the container body side is completed. Similarly, the liquid in the measuring chamber tends to flow down. Therefore, there is an inconvenience that there is uncertainty about the accuracy of the measuring function itself of measuring a predetermined amount of liquid.

Further, in Patent Document 2 in which the powder or granular material is weighed by using the urging force of the spring and the weighed powder or granular material is separated from the inside of the container body, the spring is attached as the cap opening operation progresses. In the process in which the force is gradually released and the measuring member moves upward until it comes into contact with the lower end edge of the pipe, there is a possibility that the lower end opening of the pipe and the inside of the container body communicate with each other. Therefore, unlike the powder or granular material, when the liquid is filled in the container body, the liquid may invade the pipe and the measuring function itself may be impaired.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a quantitative injection container capable of eliminating the above-mentioned inconveniences. That is, it is an object of the present invention to provide a quantitative pouring container capable of accurate weighing and easy and reliable derivation of the measured liquid.

The quantitative dispensing container of the present invention is
A container body having a mouth portion and a pipe portion extending downward from the mouth portion, and an internal space partitioned by the pipe portion into a lead-out space inside the pipe portion and a liquid storage space outside the pipe portion.
A movable member supported by the container body so as to be able to move up and down while maintaining a state of communicating with the pipe portion.
It has a shaft portion extending in the vertical direction in the pipe portion and a measuring portion provided at the lower end portion of the shaft portion and forming a predetermined amount of measuring space, and is in a descending state with respect to the pipe portion in conjunction with the movable member. An upper end portion of the shaft portion is supported by the movable member so as to move up and down between the shaft portion and the ascending state, and a measuring member provided with a closing portion in either the shaft portion or the measuring portion is provided. ,
The pipe portion has a small diameter portion that opens downward with a diameter smaller than that of the upper portion at the lower end position, and the closed portion slides with respect to the inner peripheral surface of the small diameter portion of the pipe portion in the descending state. By closing the small diameter portion as closely as possible, the lead-out space in the pipe portion and the measurement space of the measuring portion are blocked, while in the raised state, the lead-out space in the pipe portion is separated upward from the small diameter portion. The space is configured to communicate with the measuring space of the measuring unit, and the measuring unit is separated downward from the lower end opening of the pipe portion in the descending state, and the measuring space of the measuring unit communicates with the storage space. On the other hand, in the ascending state, the lower end opening of the pipe portion is closed to block the measuring space from the storage space, and the measuring space is positioned so as to communicate with the lead-out space. Can be.

Preferably, the liquid pouring container of the present invention has a container body for containing the liquid, a pipe portion extending vertically from the mouth portion in the container body and a pipe portion hanging in the X direction of the central axis, and the pipe portion. A movable member supported by the container body so as to be able to move up and down in the central axial direction while maintaining a state of communication with the container body, and a shaft portion having a measuring portion at the lower end extend in the pipe portion in the central axial direction to form the movable member. A rod-shaped measuring member whose upper end of the shaft portion is supported by the movable member can be provided so as to interlock. Here, the inside of the container body is divided by the pipe portion into a lead-out space inside the pipe portion and a storage space for storing liquid except the inside of the pipe portion, and the upper portion at the lower end position as the pipe portion. It is provided with a small-diameter portion that has a smaller diameter and opens downward, and is supported as the measuring member so as to be able to move up and down between the lowered state and the raised state in the central axis direction. To switch between a shutoff state in which the small diameter portion is slidably close to the inner peripheral surface of the small diameter portion of the pipe portion and the small diameter portion is closed, and a communication state in which a gap is opened between the inner peripheral surface of the small diameter portion. A diameter changing portion (closed portion) may be provided at the lower end portion of the shaft portion. Then, in the descending state of the measuring portion and the diameter changing portion, the diameter changing portion keeps the small diameter portion of the pipe portion in a closed state, and the measuring portion moves downward from the lower end opening of the pipe portion. While it is positioned in a state of being separated and communicating with the storage space, in the ascending state, the diameter changing portion moves to a portion above the small diameter portion of the pipe portion to open the small diameter portion and the weighing portion. The portion may be configured to cover the lower end opening of the pipe portion, shield the inside of the pipe portion from the storage space, and position the measuring portion in a state of communicating with the lead-out space.

In the case of the present invention, the measuring member is moved up and down together with the movable member, and accordingly, the weighing space at the lower end of the measuring member is communicated with the storage space from the descending state, and is cut off from the storage space to be a lead-out space in the pipe portion. It will go up and down to the ascending state where the weighing space is communicated. As a result, the liquid filled in the measuring space of the measuring unit in the descending state can be separated from the storage space by converting the measuring member into the ascending state. This separation makes it possible to accurately weigh a predetermined amount of liquid, and at the same time, it is possible to lead the weighed liquid to the derivation space and pour it through the derivation space.

Preferably, the closed portion and the measuring portion are blocked so that the measuring space of the measuring portion is shut off from the storage space before the closed portion is separated upward from the small diameter portion in the process from the descending state to the rising state. May be configured. According to such a configuration, the storage space does not become connected to the derived space in the process from the descending state to the ascending state, and the weighing can always be performed accurately.

In the quantitative injection container of the present invention, a cap that is detachably screwed to the container body by a rotation operation is provided, and as a movable member, a nozzle member having a nozzle hole at the tip is used, and as a cap, the nozzle member is engaged. The measuring member is provided with an engaging portion for detachably engaging and transmitting the elevating operation force of the cap to the nozzle member, and the measuring member is moved by the elevating operation based on the rotation operation for attaching and detaching the cap. It can be configured to move up and down between the descending state and the ascending state together with the movable member. By doing so, for example, when the rotation operation is performed to open the cap, the cap rises with respect to the container body, and the rising force is transmitted to the nozzle member and the measuring member via the engaging portion, and the nozzle member and the measuring member It is possible to raise the measuring member from the lowered state to the raised state. That is, the nozzle member and the measuring member can be raised and lowered by the rotation operation for opening and closing the cap, whereby the measuring unit can be reliably converted into the lowered state and the raised state. can. This conversion from the descending state to the ascending state enables the liquid to be separated and weighed by the measuring unit, and the measured predetermined amount of liquid can be led out to the derivation space.

Further, in the fixed quantity pouring container of the present invention, the container body has a nozzle hole at the tip and is rotatable around the axis of the shaft portion at a fixed position in the vertical direction (preferably the axial direction of the central axis). As a movable member, it is engaged with the container body so as to move up and down in the axial direction of the axis by rotating spirally around the axis (preferably around the center axis). It is composed of the elevating and lowering actuating members, and the nozzle member can be engaged with the elevating and lowering actuating member so as to be able to transmit a rotational force to the elevating and lowering actuating member. By doing so, when the nozzle member is rotated around the axis center, the rotational force is transmitted to the elevating operation member, and when the elevating operation member is spirally rotated around the axis center, the elevating operation is performed. The member will be raised and lowered. Along with the elevating operation of the elevating operation member, the measuring member also elevates and is surely converted into a descending state and an ascending state. Therefore, when the liquid filled in the measuring unit in the descending state is separated and the weighing is completed in the ascending state, the liquid can be taken out to the derivation space.

Further, in the quantitative pouring container of the present invention, a nozzle member having a nozzle hole at the tip thereof is provided, and as a movable member, the container rotates spirally around the axis of the shaft portion (preferably around the center axis). The nozzle member can be configured by the elevating and lowering actuating member engaged with the container body so as to elevate and descend in the axial direction of the axial center, and the nozzle member can be connected to the elevating and lowering actuating member so as to be able to rotate together with the elevating and lowering actuating member. By doing so, by rotating the nozzle member around the axis, the elevating and lowering actuating member also rotates, and as a result, the elevating and lowering actuating member is moved up and down. Along with the elevating operation of this elevating operation member, the measuring member also elevates and elevates between the descending state and the ascending state, and the liquid filled in the measuring unit in the descending state is separated when the elevating state is reached and the weighing is completed. , Derivation to the derivation space is possible.

When the above movable member is composed of an elevating and lowering actuating member, the movable member moves up and down in the axial direction of the axial center by rotating spirally around the axial center of the shaft portion (preferably around the central axis) with respect to the container body. A cap is provided so as to be engaged with the nozzle member, and the cap can be engaged with the nozzle member so as to be able to transmit a rotational force to the nozzle member. By doing so, if the rotation operation is performed to open and close the cap, the rotational force is transmitted to the nozzle member, and as a result, the elevating operation member can be rotationally operated. By this rotational operation, an ascending / descending operation is performed between the descending state and the ascending state of the measuring member, and the liquid can be separated / measured by the measuring unit and the liquid can be taken out to the delivery space after the measurement.

Further, in the above-mentioned quantitative injection container of the present invention, the measuring portion is composed of a pair of plate-shaped portions protruding from the shaft portion to the outer peripheral side at predetermined intervals in the vertical direction, and the pair of plate-shaped portions. The space between them can be the measuring space. In this case, the vertical dimension of the small diameter portion of the pipe portion is set longer than the vertical spacing between the pair of plate-shaped portions, and the closed portion (diameter) is set. The changing portion) can be composed of the upper plate-shaped portion of the pair of plate-shaped portions having a diameter larger than that of the shaft portion. With this configuration, in the descending state of the measuring member, the side of the measuring space between the pair of plate-shaped portions is opened with respect to the storage space, and the measuring space communicates with the storage space to provide the measuring space. As the liquid fills the inside, the upper plate-shaped portion (closed portion) comes into close contact with the inner peripheral surface of the small diameter portion of the pipe portion and closes the lower end opening of the pipe portion. On the other hand, when the measuring member reaches the raised state, the lower plate-shaped portion is in close contact with the inner peripheral surface of the small diameter portion of the pipe portion to maintain the closed state of the lower end opening of the pipe portion, and the upper plate-shaped portion is moved. The side of the measuring space is opened to the out-licensing space from the pipe portion on the upper side of the small-diameter portion, and the measuring space communicates with the out-licensing space. This makes it possible to separate and weigh the liquid that fills the weighing space between the pair of plate-shaped portions, and to derive the measured liquid to the out-licensing space.

Further, in the fixed quantity pouring container of the present invention, the measuring portion can be configured in a cup shape having the internal space as the measuring space, and in this case, the upper end opening edge of the measuring portion is the lower end of the pipe portion. The closed portion can be configured to be slidable in the vertical direction while being fitted in close contact with the outer peripheral surface of the portion, and the closed portion can be configured by a bulging portion formed by bulging on the shaft portion of the measuring member. With this configuration, when the measuring member is in the lowered state, the upper end opening of the measuring unit is opened with respect to the storage space, the measuring space communicates with the storage space, and the measuring space of the measuring unit is filled with liquid. At the same time, the bulging portion comes into close contact with the inner peripheral surface of the small diameter portion of the pipe portion and closes the lower end opening of the pipe portion. On the other hand, when the measuring member reaches the raised state, the upper end opening edge of the measuring portion fits in close contact with the outer peripheral surface of the lower end portion of the pipe portion, and the lower end opening of the pipe portion is closed to create a measuring space and a lead-out space. While shutting off from the storage space, the bulging portion moves to a portion above the small diameter portion of the pipe portion, and the measuring space of the measuring portion is communicated with the lead-out space. This makes it possible to separate and weigh the liquid filled in the measuring space of the measuring unit configured in a cup shape, and to derive the measured liquid to the out-licensing space.

Further, in the quantitative dispensing container of the present invention, the measuring portion is configured in a cup shape having an internal space as the measuring space, and the upper end opening edge of the measuring portion is in close contact with the outer peripheral surface of the lower end portion of the pipe portion. The closed portion is configured to be slidable in the vertical direction while being fitted externally in the state, and the closed portion is configured by a shaft portion of the measuring member that is slidably in close contact with the inner peripheral surface of the small diameter portion of the pipe portion. The measuring unit may be connected to the shaft portion via a connecting shaft having a diameter smaller than that of the shaft portion and which is connected to the lower end of the shaft portion. With this configuration, in the lowered state of the measuring member, the upper end opening of the measuring part is opened with respect to the storage space, the measuring space communicates with the storage space, and the container is filled with the liquid, and the measuring member is filled. The shaft portion of the pipe portion is in close contact with the inner peripheral surface of the small diameter portion of the pipe portion to close the lower end opening of the pipe portion. On the other hand, when the measuring member reaches the raised state, the upper end opening edge of the container fits in close contact with the outer peripheral surface of the lower end portion of the pipe portion, and the lower end opening of the pipe portion is closed to store the weighing space and the lead-out space. While blocking from the space, the shaft part moves to the upper part from the small diameter part, and the measuring space of the measuring part becomes the lead-out space by the gap between the connecting shaft of the small diameter below the shaft part and the small diameter part of the pipe part. It will be communicated. This makes it possible to separate and weigh the liquid filled in the weighing space of the cup-shaped measuring unit and to derive the measured liquid to the out-licensing space.

As described above, according to the quantitative injection container of the present invention, accurate weighing and easy and reliable derivation of the measured liquid can be achieved. That is, when the measuring member is moved up and down together with the movable member, the measuring portion at the lower end of the measuring member is communicated with the storage space from the descending state, and the measuring portion is communicated with the lead-out space in the pipe portion. It will go up and down to the state. As a result, the liquid filled in the measuring unit in the descending state can be reliably separated from the storage space by converting the measuring member into the ascending state. By this separation, a predetermined amount of liquid can be accurately weighed, and at the same time, the weighed liquid can be led out to the derivation space and poured out through the derivation space.

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

<First Embodiment>
FIG. 1 shows a quantitative pouring container according to the first embodiment of the present invention. When not in use, this fixed-quantity dispensing container is stored with a liquid (for example, a liquid such as a hair restorer) filled inside, and when in use, only a certain amount of liquid measured from the internal liquid is poured (applied). It is something that can be done. Then, this fixed-quantity pouring container is weighed only by removing the cap in an upright state, and can be dispensed by keeping it in an inverted state as it is. There is no limit to the liquid that can be filled inside, and even if it is a highly volatile liquid such as a hair restorer, it will not cause any inconvenience and maintain a reliable storage state without the risk of liquid leakage. It is possible to achieve accurate weighing and easy and reliable pouring. In the following description, the state shown in FIG. 1 is referred to as an upright state, and the state of being inverted upside down is referred to as an inverted state. The axis X is the central axis of the fixed quantity pouring container and extends in the vertical direction. Of the "elevations" that are forward and backward movements in the axis X direction, "ascending" means moving upward in FIG. 1 along the axis X, and "descending" means moving downward.

The quantitative pouring container is configured with the following components. That is, the fixed-quantity pouring container includes a container main body 2 for filling a liquid, a pipe portion 22 hanging from the inside of the mouth portion 21 of the container main body 2 in an inner tubular shape along the axis X, and a container main body 2. The nozzle member 3 is coupled to the mouth portion 21 so as to be relatively movable in the axis X direction (movable in the axis X direction), and the nozzle member 3 is covered from above in the axis X direction with respect to the mouth portion 21. A nozzle cover 4 that is connected so as not to move relative to each other, a spring valve 5 that opens and closes the nozzle hole 30 of the nozzle member 3 and keeps the nozzle hole 30 in a closed state by an upward urging force, and a nozzle member 3. A rod-shaped measuring member 6 whose upper end is connected to the inner portion of the container body 2, a cap 7 screwed onto the upper part of the container body 2 in a state of being engageably engaged with the nozzle member 3, and a bottom portion of the container body 2. It is configured to include a bottom lid 8 for detachably closing the opening 23. Here, the nozzle member 3 constitutes a "movable member".

As will be clear from the detailed description below, in the quantitative pouring container, the nozzle member 3 and the measuring member 6 connected to the nozzle member 3 are driven upward by the opening operation of the cap 7, whereby the measuring member 6 is used for weighing. And, the measured liquid can be taken out into the pipe portion 22 in a state of being shielded from the space in the container main body 2. A similar function can be achieved by directly pulling up the nozzle member 3, and the cap 7 is not an essential component. However, the significance of the existence of the cap 7 is that the measurement by the measuring member 6 is completed and the injection can be performed immediately by the user's natural operation of opening the cap 7 for the use of the fixed quantity pouring container. There is. All of the above components can be formed by synthetic resin molding. Hereinafter, each component will be described in detail.

The container body 2 is formed in a cylindrical shape extending along the axis X, for example, the mouth portion 21 on the upper end side has a slightly smaller diameter, the pipe portion 22 is integrally formed at the inner position of the mouth portion 21, and the lower end side is open. The lower end opening 23 is set. The lower end of the pipe portion 22 is hung down to a predetermined position in relation to the bottom lid 8 connected to the bottom portion in the container main body 2. At the lower end of the pipe portion 22, a small diameter tubular portion 221 having an inner peripheral surface shape having a diameter smaller than that of the adjacent upper portion is formed over a predetermined range above the lower end opening. As will be clarified in the explanation described later, the lower end opening of the small diameter tubular portion 221 is the measuring portion 62 regardless of whether the measuring portion 62 of the measuring member 6 is in the lowered state, the raised state, or the intermediate stage between the two states. It is closed by any one of the pair of plate-shaped portions 621 and 622 constituting the above. Therefore, the inside of the container main body 2 is a storage space 24 which is a donut annular space on the outer peripheral side of the pipe portion 22 and a space inside the pipe portion 22 which is isolated from the storage space 24 at the lower end opening. It will be partitioned into space 25. The storage space 24 is a space for storing the liquid, and the lead-out space 25 is a space for leading the measured liquid to the nozzle hole 30.

Further, a flange-shaped locking convex edge 211 protruding toward the outer peripheral side is formed in the vicinity of the base of the small-diameter tubular wall constituting the mouth portion 21, and the nozzle cover 4 is provided on the lower surface of the locking convex edge 211. The locking projection 41 protruding from the lower end edge of the to the inner peripheral side is engaged. Further, the locking projection 41 is engaged with the locking convex edge 211 in a state of being in contact with the stepped portion of the mouth portion 21 from above, whereby the nozzle cover 4 moves relative to the container body 2 in the axis X direction. It will be impossible to combine. Further, a screw 26 is formed around the lower portion of the mouth portion 21, and a screw 71 on the inner peripheral surface of the lower end portion of the cap 7 is screwed into the screw 26 to detachably close the cap 7. be able to. By closing the cap 7 in the closed cap state, the container body 2 and the container body 2 have a cylindrical appearance as a whole. The pipe portion 22 can be formed separately from the container body 2, and both the separate pipe portion and the container body can be assembled and integrated with each other.

The nozzle member 3 includes a substantially hemispherical nozzle portion 31 having a nozzle hole 30 formed at the apex. A stepped surface 32 extending to the outer peripheral side is formed at the base of the nozzle portion 31, a midfoot portion 33 extending downward from the inner position of the stepped surface 32, and an outer foot extending downward from the outer position of the stepped surface 32. A double-cylindrical mounting portion composed of the portion 34 is formed. The outer peripheral surface of the midfoot portion 33 is slightly press-fitted into the inner peripheral surface of the mouth portion 21 from above, whereby the inside and outside are sealed and the nozzle member 3 is reliably moved in the axis X direction. I support it to be a move to. Further, the outer foot portion 34 can abut against the upper surface of the locking convex edge 211 from above and abut on it, whereby the nozzle member 3 can be positioned at a specific relative position with respect to the container body 2, that is, the nozzle member 3 can be positioned at a predetermined descending position. It has become like. The positional relationship between the two is set so that the cap 7 is closed while the nozzle member 3 is in the lowered position. At least three ribs 35, 35, ... (See also FIG. 2) are coupled to the inner surface of the nozzle portion 31 in a state of being arranged in the radial direction with respect to the axis X. An engaging groove 351 having a predetermined width in the axis X direction is formed in each rib 35, and the outer peripheral edge of the head 61 of the measuring member 6 is formed in the engaging grooves 351, 351, ... Of these ribs 35, 35, ... Is sandwiched. As a result, the measuring member 6 and the nozzle member 3 are integrally coupled to each other in a state where the measuring member 6 extends along the axis X.

Further, the annular pedestal 51 on the base end side of the spring valve 5 cannot move relative to the inner end faces of the ribs 35, 35, ... It is fitted. Then, the convex shaft portion 52 (see FIG. 3A) on the tip end side of the spring valve 5 receives the elastic urging force from the elastic arm portion 53 and is internally fitted into the nozzle hole 30 from the bottom to the top. A part of the tip is made to protrude from the nozzle hole 30. In this state, the valve portion 54 (see also FIG. 4) extending from the lower position of the shaft portion 52 to the periphery is pressed upward against the seat surface formed by the inner peripheral surface below the nozzle hole 30. The nozzle holes 30 are brought into close contact with each other to keep the nozzle holes 30 in the closed state. Reference numeral 521 in FIGS. 3A and 4 is a concave groove, and when at least one (three in the example) is formed around the shaft portion 52 and the shaft portion 52 protruding from the nozzle hole 30 is pushed. The valve portion 54 is separated from the seat surface in the nozzle portion 31 (see FIG. 3B), and the nozzle hole 30 is in an open state, whereby the space inside the nozzle member 3 and the inside of the pipe portion 22 and the outside through the concave groove 521 are opened. And are in communication with each other.

The nozzle cover 4 includes a donut annular downward surface 4A and a tubular portion 42 extending downward from the outer periphery thereof. The downward surface 4A acts as a stopper that hits the stepped surface 32 of the nozzle member 3 and stops the ascending of the nozzle member 3 at a predetermined ascending position when the nozzle member 3 is lifted upward from the descending position as described later. belongs to. Therefore, the nozzle cover 4 is coupled to the container body 2 by the locking projection 41 at the lower end edge of the tubular portion 42, and is fixed so as not to be relatively movable in the axis X direction (vertical direction).

The measuring member 6 is a rod-shaped shaft portion 63 for connecting the head portion 61 projecting to the outer peripheral side on the upper end side, the measuring portion 62 opened only on the outer peripheral side on the lower end side, and the head portion 61 and the measuring portion 62 to each other. It is configured with and. As shown in FIG. 5, the measuring unit 62 is composed of a pair of plate-shaped portions 621 and 622 protruding from the shaft unit 63 to the outer peripheral side in a state of being separated from each other by a predetermined distance in the axis X direction (vertical direction). A weighing space is formed by the space between the pair of plate-shaped portions 621 and 622, and the space between the upper and lower plate-shaped portions 621 and 622 is opened in the outer peripheral direction to form a side opening 624. Both plate-shaped portions 621 and 622 are connected to each other by ribs 623, 623, ... Radiating from the axis X between the two, and are reinforced so that the distance between the two is always the same. Both outer peripheral surfaces of the upper and lower plate-shaped portions 621 and 622 have the same projected shape on a plane orthogonal to the axis X. Moreover, both outer peripheral surfaces of the plate-shaped portions 621 and 622 have the same shape as the inner peripheral surface of the small diameter tubular portion 221 formed at the lower end of the pipe portion 22, and the inside of the small diameter tubular portion 221 is slid in the axis X direction. It is formed so that it can move. That is, each outer peripheral surface of the plate-shaped portions 621 and 622 is formed so as to be slidable in the axis X direction while being in close contact with the inner peripheral surface of the small diameter tubular portion 221.

The cap 7 includes a screw portion 71, an engaging portion 72 that engages with and disengages from the nozzle member 3, and a support foot portion 73 on the inner peripheral surface of the lower end portion thereof. That is, on the crown portion of the nozzle member 3 (see FIG. 3A), a small-diameter neck portion 36 is formed on the outer peripheral portion of the hole edge portion constituting the nozzle hole 30, while the inner surface of the zenith portion of the cap 7 is formed. An annular engaging portion 72 projecting downward is formed. An inwardly facing engaging claw 721 is formed at the tip of the engaging portion 72, and the engaging claw 721 sandwiches and engages the neck portion 36 so that the cap 7 and the nozzle member 3 are detachably connected to each other. It has become so. When the engaging claw 721 engages with the neck portion 36, the nozzle member 3 and the measuring member 6 are raised and lowered as the cap 7 moves up and down, and the engaging claw 721 is raised and lowered. The cap 7 and the nozzle member 3 are separated from each other by disengaging the engagement. An annular support foot portion 73 is formed at the inner peripheral side position of the engaging portion 72, and the hole edge portion on which the neck portion 36 is formed with the engaging claw 721 fitted into the neck portion 36. It is designed to come into contact with the upper surface of the.

The cap 7 can cover the upper part of the container body 2 in a closed state by screwing the screws 71 and 26, and the cap 7 is opened and closed by rotating the cap 7. Then, when the cap 7 is rotated, the cap 7 moves up and down based on the screwing of the screws 71 and 26. While the cap 7 is tightened to the lowest position by the screws 71 and 26 (closed cap state), the nozzle member 3 and the measuring member 6 are positioned in a predetermined lowered state (state shown in FIG. 6A). The nozzle member 3 and the measuring member 6 are in a predetermined raised state (open end state) in a state where the cap is opened to the uppermost position where the screws 71 and 26 are disengaged from each other by rotating in the loosening direction (open end state). It is positioned in the state shown in FIG. 6 (c)).

When the cap 7 is in the closed cap state and the nozzle member 3 and the measuring member 6 are in the lowered state (see FIG. 6A), the lower plate-shaped portion 622 constituting the measuring portion 62 is the bottom lid 8. The outer peripheral surface of the upper plate-shaped portion 621 is in close contact with the inner peripheral surface of the lower end portion of the small diameter tubular portion 221 of the pipe portion 22 and the lower end opening of the small diameter tubular portion 221 is closed. There is. When the measuring unit 62 is in such a lowered state, the side opening 624 of the measuring unit 62 is communicated with the storage space 24, and the liquid between the upper and lower plate-shaped portions 621 and 622 is the same as in the storage space 24. Will be filled.

When the cap 7 is opened to the open end state and the nozzle member 3 and the measuring member 6 are in the raised state (see FIG. 6 (c)), the upper plate-shaped portion 621 is a small diameter tubular portion. It is located above 221 and the outer peripheral surface of the lower plate-shaped portion 622 is in close contact with the inner peripheral surface of the small diameter tubular portion 221 to close the lower end opening of the small diameter tubular portion 221. When the measuring portion 62 is in such an elevated state, the outer peripheral surface of the upper plate-shaped portion 621 is out of close contact with the small-diameter tubular portion 621, so that the side opening 624 faces the lead-out space 25 and communicates with the measuring portion 62. Will be done.

Then, when the cap 7 is in the middle of the operation from the closed cap state to the open end state, that is, when the measuring unit 62 is in the intermediate state between the lowered state and the raised state (see FIG. 6B), the upper side is used. The plate-shaped portion 621 moves up and down while maintaining its outer peripheral surface in close contact with the inner peripheral surface of the small-diameter tubular portion 221 while the upper plate-shaped portion 621 moves to the large-diameter portion above the small-diameter tubular portion 221. When the close contact state is released, the lower plate-shaped portion 622 is internally fitted into the inner peripheral surface from the lower end opening of the small diameter cylinder portion 221 and the outer peripheral surface thereof is the small diameter cylinder portion. It will be in close contact with the inner peripheral surface of the portion 221. From the above, the lower end opening of the pipe portion 22 is always maintained in a closed state by having one or both of the upper and lower plate-shaped portions 621 and 622 of the measuring portion 62 in close contact with the small diameter cylinder portion 221 and always a storage space. 24 and the derivation space 25 are isolated from each other. Here, the small-diameter tubular portion 221 constitutes the "small-diameter portion" of the pipe portion 22, and the upper plate-shaped portion 621 constitutes the "closed portion".

Further, the bottom lid 8 is configured to include a midfoot portion 81 that is press-fitted into the inner peripheral surface of the bottom portion from the lower end opening 23 of the container body 2, and a lid wall portion 82. A recess 821 is formed at the center of the lid wall portion 82. The recess 821 has substantially the same planar shape as the plate-shaped portion 622 so that the lower plate-shaped portion 622 of the measuring portion 62 can enter from above, and has a depth lower than the inner height of the upper and lower plate-shaped portions 621 and 622. Has a sword. The positional relationship between the recess 821 and the measuring cylinder portion 221 of the pipe portion 22 is determined in relation to the upper and lower plate-shaped portions 621 and 622 of the measuring portion 62.

That is, as shown in detail in FIG. 6A, when the measuring member 6 is in the lowered state, the lower plate-shaped portion 622 is housed in the recess 821 (preferably landing on the bottom of the recess 821). In addition, the side opening 624 is the upper end of the recess 821 in a state where the outer peripheral surface of the upper plate-shaped portion 621 is fitted inside the inner peripheral surface of the measuring cylinder portion 221 and the inside of the pipe portion 22 is shielded from the storage space 24. It is set so as to communicate with the storage space 24 of the container body 2 through the gap 241 between the small diameter cylinder portion 221 and the lower end of the small diameter cylinder portion 221.

The above-mentioned fixed-quantity pouring container is assembled as follows and filled with a liquid. The pedestal 51 is fitted into the nozzle hole 30 of the nozzle member 3 with the plug portion 52 of the spring valve 5 inserted from the inside and closed, and then the head 61 of the measuring member 6 is engaged with the ribs 35, 35, ... The nozzle member 3, the spring valve 5, and the measuring member 6 are assembled by fitting into the grooves 351, 351, .... The measuring member 6 in the assembled state is inserted into the container main body 2 from the measuring unit 62, and the measuring unit 62 is pushed against the small diameter tubular portion 221 so that only the lower plate-shaped portion 622 protrudes and the nozzle member 3 The midfoot portion 33 is press-fitted into the inner peripheral surface of the mouth portion 21. Then, the nozzle cover 4 is connected to the container body 2 and the cap 7 is screwed into the closed cap state. Finally, with the top and bottom reversed, a predetermined amount of liquid such as a chemical solution is filled in the storage space 24 from the lower end opening 23 at the bottom of the container body 2, and then the bottom lid 8 is fitted to fit the bottom lid 8 of the container body 2. Once the bottom is closed, the metered dose container can be used.

Next, the method of using this fixed-quantity dispensing container will be described with reference to FIG. 7. First, the cap 7 in the closed cap state is twisted and rotated to open the cap (see the figure at the left end of FIG. 7). .. Then, as the cap 7 rises, the nozzle member 3 and the measuring member 6 engaged by the engaging portion 72 are pulled up and raised. At this time, when the lower plate-shaped portion 622 of the measuring portion 62, which was in the lowered state, rises and comes into close contact with the inner peripheral surface of the small diameter tubular portion 221 (see the figure of the left and right center portions in FIG. 7, and FIG. 6). (See also (b)), the side opening 624 between the upper and lower plate-shaped portions 621 and 622 is closed by the inner peripheral surface of the measuring cylinder portion 221, whereby the volume between the upper and lower plate-shaped portions 621 and 622 (see also). For example, a liquid corresponding to 5 ml) will be weighed. Then, when the cap 7 is opened to the open end state, it reaches the raised state (see the figure of the right end portion of FIG. 7 and also see FIG. 6 (c)), and the upper plate-shaped portion 621 is larger than the measuring cylinder portion 221. Moving upward, the side opening 624 communicates with the lead-out space 25.

Next, the cap 7 in the open end state is removed from the neck portion 36 by, for example, prying or pulling out (see the figure on the left side of FIG. 8), and the cap 7 is removed from the container body 2 and separated. Then, the top and bottom are reversed to make it an inverted state, and in that state, the plug portion 52 is pressed against the affected portion (for example, the scalp) H. As a result, the elastic arm portions 53, 53, ... Of the spring valve 5 are bent, the plug portion 52 is retracted (see also FIG. 3B), and the nozzle hole 30 is opened through the concave groove 521. The liquid that has reached the tip of the nozzle unit 3 from the measuring unit 62 through the lead-out space 25 is poured out to the scalp H through the concave groove 521, and the liquid Q can be applied to the scalp. On the other hand, the inside of the derivation space 25 is replaced with the outside air and becomes empty. That is, by pressing the plug portion 52 against the scalp H or the like, the liquid measured by the measuring unit 62 can be poured out from the nozzle hole 30.

After use, the fixed-quantity dispensing container is returned to the upright state, covered with the cap 7, and slightly pushed in so that the engaging claw 721 of the engaging portion 72 fits into the neck portion 36 of the nozzle member 3 and at the same time, the support foot. The portion 73 comes into contact with the nozzle member 3 from above. Then, when the cap 7 is screwed in the closing direction to the closed state, the nozzle member 3 and the measuring member 6 are pushed down by the lowering of the cap 7, and the measuring unit 62 returns to the original lowered state.

According to the above-mentioned fixed-quantity pouring container, even if a predetermined amount of liquid is to be poured out from the container body 2 in which the liquid is stored, the predetermined amount of liquid can be accurately measured simply by opening the cap 7. , The weighed liquid can be reliably taken out (poured). That is, the cap 7 opening operation is usually an operation that is always necessary for a container with a cap, and the weighing and pouring can be performed accurately and reliably only by performing the cap 7 opening operation. It will be possible to eliminate the need for other special operations.

In addition, when not in use, that is, in the closed state in which the cap 7 is put on the container body 2, the measuring member 6 is lowered and the measuring unit 62 closes the small diameter cylinder portion 221. Can be isolated from each other with the storage space 24. Further, even in the process of reaching the raised state of the measuring member 6 or in the raised state by removing the cap 7, the measuring unit 62 can maintain the closed state of the small diameter cylinder portion 221, whereby it is reliable. The derivation space 25 can be isolated from the storage space 24. As described above, the liquid contained and stored in the container body 2 is sealed regardless of whether it is in the lowered or raised state, or even if the fixed-quantity dispensing container is placed in a state such as lying down instead of being upright. The state can be maintained, and the occurrence of liquid leakage or the like can be avoided. Moreover, if the cap 7 is in the open cap state, it has already been converted into a measurable state by the open cap operation, and it looks like it is in a state where a certain amount of liquid can be poured out and applied. The user can grasp it only by itself.

<Second Embodiment>
9 and 10 show a quantitative pouring container according to a second embodiment of the present invention. Similar to that of the first embodiment, this fixed quantity pouring container is stored in a state where a liquid (for example, a liquid agent such as a hair restorer) is filled inside when not in use, and is constant measured from the liquid inside when in use. Only a quantity of liquid can be poured (applied). Then, as in the first embodiment, this fixed quantity pouring container is weighed only by removing the cap in an upright state, and can be dispensed by keeping it in an inverted state as it is. However, the quantitative injection container of the second embodiment is different from the first embodiment in that the member related to the internal weighing is spirally guided to move up and down, and the member moves up and down by pulling up and pushing down without rotating.

There is no limit to the liquid that can be filled inside, and even if it is a highly volatile liquid such as a hair restorer, it will not cause any inconvenience and maintain a reliable storage state without the risk of liquid leakage. It is the same as the first embodiment in that accurate weighing and easy and reliable pouring can be achieved. In the following description, the state shown in FIG. 9 is referred to as an upright state, and the state of being inverted upside down is referred to as an inverted state. The axis X is the central axis of the fixed quantity pouring container and extends in the vertical direction. Of the "elevations" that are forward and backward movements in the axis X direction, "ascending" means moving upward in FIG. 9 along the axis X, and "descending" means moving downward.

The quantitative pouring container of the second embodiment is configured to include the following components. That is, the fixed-quantity pouring container includes a container main body 12 for filling a liquid, a pipe portion 13 hanging from the inside of the mouth portion 121 of the container main body 12 in an inner tubular shape along the axis X, and a container main body 12. The nozzle member 14 is coupled to the mouth portion 121 so as not to be relatively movable in the axis X direction, and the nozzle hole 140 of the nozzle member 14 is opened and closed, and the nozzle hole 140 is closed by an upward urging force. A spring valve 15 for maintaining the state, a rod-shaped measuring member 16 having a measuring portion 161 at the lower end and extending in the axis X direction, and a rod-shaped measuring member 16 connected to the head 163 of the measuring member 16 for raising and lowering the measuring member 16. The elevating operation member 17, the cap 18 that is detachably screwed to the upper part of the container body 12 so as to cover the nozzle member 14 from above, and the bottom opening 122 of the container body 12 are detachably closed and the container body is closed. It is configured to include a bottom lid 19 for forming the bottom of the twelve. Here, the elevating actuating member 17 constitutes a "movable member".

As will be clear from the detailed description below, in the quantitative pouring container, the nozzle member 14 is rotationally operated based on the opening operation of the cap 18, and the elevating and lowering actuating member 17 is guided ascending as the nozzle member 14 is rotated. As the elevating and lowering operation member 17 rises, the measuring member 16 also rises and operates, whereby the weighing by the measuring member 16 and the derivation of the measuring liquid into the pipe portion 13 in a state of being shielded from the space in the container main body 12 are performed. It is possible. A similar function can be achieved by directly rotating the nozzle member 14, and the cap 18 is not an essential component. However, the significance of the existence of the cap 18 is that the measurement by the measuring member 16 is completed and the injection can be performed immediately by the user's natural operation of opening the cap 18 for the use of the fixed quantity pouring container. There is. All of the above components can be formed by synthetic resin molding. Hereinafter, each component will be described in detail.

The container body 12 is formed in a cylindrical shape extending along the axis X, for example, the upper end side mouth portion 121 has a slightly smaller diameter, and the pipe portion 13 inserted inside the mouth portion 121 hangs downward. It is fixed. A flange 131 extending to the outer peripheral side is formed at the upper end of the pipe portion 13, and the flange 131 is fixed in close contact with the inner peripheral flange 123 at the base of the mouth portion 121 by, for example, undercut fitting. As a result, the relative movement in the vertical direction is prevented and the seal is applied. The lower end of the pipe portion 13 is hung down to a predetermined position in relation to the bottom lid 8 connected to the bottom portion in the container body 12.

Then, at the lower end of the pipe portion 13, an inner cylindrical small-diameter tubular portion 132 having a predetermined length in the axis X direction and having a predetermined inner diameter is formed, while the shaft portion of the measuring member 16 is formed. At the lower end portion of 162, a bulging portion 164 having a diameter larger than that of other portions is formed so as to bulge toward the outer peripheral side. The small-diameter tubular portion 132 is in close contact with or out of close contact with the outer peripheral surface of the bulging portion 164, so that the opening of the small-diameter tubular portion 132 can be switched to a closed state or an open state. Due to the presence of the pipe portion 13 and the bulging portion 164, the inside of the container body 12 is shielded from the storage space 124, which is a donut annular space on the outer peripheral side of the pipe portion 13, and the storage space 124 at the lower end opening. It will be partitioned into the derivation space 125, which is the space inside the pipe portion 13 in the state of being in the state. Here, the storage space 124 is a space for storing the liquid, and the derivation space 125 is a space for deriving the measured liquid. Here, the small-diameter tubular portion 132 constitutes the "small-diameter portion" of the pipe portion 13, and the bulging portion 164 constitutes the "closed portion". The lower side of the bulging portion 164 may be a shaft portion having the same diameter as the shaft portion 162 of the upper portion, but the opening cross-sectional area for communication between the inside of the measuring portion 161 and the lead-out space in the ascending state described later may be provided. It is preferable to use a small diameter shaft portion in order to make it larger.

Further, a flange-shaped locking convex edge 126 protruding toward the outer peripheral side is formed in the vicinity of the base of the small-diameter tubular wall constituting the mouth portion 121, and the nozzle member 14 is provided with respect to the lower surface of the locking convex edge 126. The nozzle member 14 is made rotatable by engaging the locking projection 141 projecting from the lower end edge to the inner peripheral side and sliding around the axis X. Further, the lower end of the nozzle member 14 is arranged in a state of being close to the step portion of the base portion of the mouth portion 121 from above, whereby the nozzle member 14 is coupled to the container body 2 so as to be relatively immovable in the axis X direction. Will be done.

Further, one or more (two in the example) spiral guide grooves 127 and 127 (see also FIG. 11) are formed on the outer peripheral surface of the mouth portion 121. The convex portion 171 of the elevating and lowering actuating member 17 is slidably fitted in the guide grooves 127 and 127, and when the elevating and lowering actuating member 17 is rotated around the axis X, the convex portion 171 becomes a spiral guide groove. The elevating operation member 17 is moved up and down by being guided by moving along 127. The top end of the guide groove 127 is bent upward and opened to the end surface of the mouth portion 121, and by fitting the convex portion 171 from above through this opening, the elevating actuating member 17 can be assembled to the container body 12. It has become.

In addition, one or more (two in the example) spiral guide grooves 128 and 128 are formed on the outer peripheral surface of the container body 12 on the lower side of the mouth portion 121. The convex portion 181 of the cap 18 is slidably fitted in the guide grooves 128 and 128, and when the cap 18 in the closed state is rotated around the axis X, the convex portion 181 moves along the guide groove 128. Guided, the cap 18 will rise. The top end of each guide groove 128 is also bent upward and opened at the outer peripheral edge of the inner peripheral flange 123, and the convex portion 181 protrudes upward from this opening so that the cap 18 can be removed from the container body 12 and separated. Can be done. By performing the reverse operation, the cap 18 can be returned to the closed state again.

The nozzle member 14 includes a substantially hemispherical nozzle portion 142 having a nozzle hole 140 formed at the apex, a middle cylinder portion 143 having a predetermined diameter that hangs down in the nozzle portion 142 from a lower position of the nozzle hole 140, and a nozzle portion 142. A step portion 144 extending from the base portion to the outer peripheral side and a cover portion 145 hanging downward from the outer peripheral end of the step portion 144 are provided. The locking projection 141 is formed inward with respect to the lower end edge of the cover portion 145, and the locking projection 141 is slidably engaged with the locking convex edge 126 as described above, whereby the nozzle member 14 is rotatably held around the axis X at a fixed position with respect to the axis X direction (vertical direction).

One or two or more (two in the example) vertical ribs 146 and 146 are formed on the inner peripheral surface of the cover portion 145 at positions 180 degrees apart in the circumferential direction, and one or more on the outer peripheral surface. The vertical concave grooves 147 and 147 (two in the illustrated example) are similarly formed at positions separated by 180 degrees in the circumferential direction. The vertical rib 146 is fitted into the vertical concave groove 175 of the elevating operation member 17 from above, whereby the rotational force from the nozzle member 14 can be transmitted to the elevating operation member 17. Further, the vertical rib 182 of the cap 18 is fitted into the vertical concave groove 147 from above, whereby the rotational force from the cap 18 can be transmitted to the nozzle member 14. In short, by rotating the cap 18, the elevating and lowering operation member 17 can be rotationally operated via the nozzle member 14, and by this rotational operation, the elevating and lowering operation member 17 itself and the weighing connected to the elevating and lowering operation member 17 are measured. The whole with the member 16 can be raised and lowered integrally.

Similar to the spring valve 5 (see FIG. 4) of the first embodiment, the spring valve 15 for opening and closing the nozzle hole 140 includes an annular pedestal 151 on the proximal end side and a convex shaft portion 152 on the distal end side (see FIG. 4). (See also FIGS. 12A and 12B), the elastic arm portion 153 connecting the two, and the valve portion 154 extending from the lower position of the shaft portion 152 to the periphery are provided. In the second embodiment, the pedestal 151 is internally fitted to the inner peripheral surface of the inner cylinder portion 143 of the nozzle member 14 so as not to be relatively movable in the axis X direction by undercut fitting. Then, the shaft portion 152 (see FIG. 12 (a)) receives the elastic urging force from the elastic arm portion 153, is internally fitted into the nozzle hole 140 from the bottom to the top, and a part of the tip protrudes from the nozzle hole 140. It is in a state of being. At the same time, due to this elastic urging force, the valve portion 154 is pressed upward against the seat surface formed by the inner peripheral surface below the nozzle hole 140 and comes into close contact with the valve portion 140, thereby keeping the nozzle hole 140 in the closed state. It is designed to do.

In this state, an annular protective cylinder 183 projecting downward from the inner surface of the top wall of the cap 18 in the closed state, which is larger than the protrusion amount of the shaft portion 152, surrounds the shaft portion 152 inside, and the lower end of the protective cylinder 183. Is in contact with the top of the nozzle portion 142. As a result, it is possible to prevent an unintended external force from acting on the shaft portion 152 and to reliably maintain the closed state of the nozzle hole 140 by the shaft portion 152. Further, reference numeral 155 in the drawings of FIGS. 12 (a) and 12 (b) is a concave groove, and at least one (three in the example) is formed around the shaft portion 152, and the shaft portion protrudes from the nozzle hole 140. When the 152 is pushed, the valve portion 154 is separated from the seat surface (see FIG. 12B), and the nozzle hole 140 is opened, whereby the elevating operating member 17 in the middle cylinder portion 143 through each concave groove 155. Each space in the inner cylinder portion 173 and the pipe portion 13, which will be described later, and the outside communicate with each other.

The elevating actuating member 17 is integrally formed with an outer cylinder portion 172, an inner cylinder portion 173, and a donut annular upper end surface 174 connecting the two at the upper end. The lower end portion of the inner cylinder portion 173 extends downward from the outer cylinder portion 172, and is internally fitted into the large diameter portion 133 of the upper end portion of the pipe portion 13. The lower end edge of the inner cylinder portion 173 is brought into close contact with the inner peripheral surface of the large diameter portion 133 so as to be slidable and rotatable around the axis X so as to be sealed. A stopper 176 is formed on the inner peripheral surface of the inner cylinder portion 173 so as to project inward, and an engaging portion 177 is formed at a position below a predetermined interval. The head 163, which will be described later, is pushed against the engaging portion 177 from below to the stopper 176, so that the head 163 is sandwiched between the stopper 176 and the engaging portion 177 and fixed. As a result, the measuring member 16 is connected to the elevating operating member 17 in a state where the relative movement in the axis X direction is prevented.

The measuring member 16 is configured in a rod shape with a measuring portion 161 on the lower end side and a shaft portion 162 having a lower end connected to the measuring portion 161 and extending upward along the axis X in the pipe portion 13. There is. A head 163 projecting to the outer peripheral side is formed at the upper end of the shaft portion 162, and one or more (two in the example) communication holes 165 are formed through the head 163. As described above, the measuring member 16 is connected to the elevating member 17 by the head 163, while the lead-out space 125 is provided by the communication hole 165, the inside of the inner cylinder portion 173 of the elevating actuating member 17, and the middle cylinder portion 143 of the nozzle member 14. The inside and the inside are communicated with each other to form one space.

As shown in detail in FIG. 13, the measuring unit 161 is a cup-shaped container that opens upward and has a measuring space of a predetermined volume inside, and is located at the lower end of the shaft portion 162, specifically below the bulging portion 164. It is connected to the extending small diameter shaft portion. This connection is performed by the engaging cylinder portion 166 formed so as to rise from the inner bottom surface of the measuring portion 161 and the engaging portion 167 formed on the small diameter shaft portion. For example, the inner surface of the engaging cylinder portion 166 is formed in an uneven shape in the axis X direction, while the outer surface of the engaging portion 167 is formed in an uneven shape corresponding to the inner surface of the engaging cylinder portion 166, and the engaging portion 167 is formed. Is press-fitted into the engaging cylinder portion 166, so that the engaging portion 167 and the engaging cylinder portion 166 are engaged with each other and connected to each other.

Further, the inner peripheral surface of the upper end opening edge 168 of the measuring portion 161 can be fitted outward in close contact with the outer peripheral surface of the lower end portion of the pipe portion 13, and while maintaining the close contact state, the axis X and the axis X can be fitted. It is formed so as to be slidable in the direction. Then, when the cap 18 is in the closed cap state (the state shown in FIG. 9), the measuring unit 161 separates downward from the lower end of the pipe unit 13 and lands in the recess 193 of the recess forming portion 191 of the bottom lid 19. It is designed to be positioned in a descending state. In this descending state, the opening formed by the upper end opening edge 168 is opened facing the storage space 124, while the outer peripheral surface of the bulging portion 164 is in close contact with the inner peripheral surface of the small diameter tubular portion 132. The lower end opening of the pipe portion 13 is closed so that the lead-out space 125 is cut off from the storage space 124.

The bottom lid 19 has a recess 193 at the center position, and covers the recess forming portion 191 in which the peripheral edge portion 194 is pushed from the bottom opening of the container body 12 into the inner peripheral surface of the bottom, and the recess 193 of the recess forming portion 191 from the outside. It is configured to include a bottom wall portion 192 for covering. The lower end of the pipe portion 13 is located near the upper end opening of the recess 193, and the recess 193 is arranged so as to be separated from the lower end of the pipe portion 13 by a predetermined distance. That is, in the descending state where the measuring unit 161 has landed on the bottom of the recess 193, there is at least a gap communicating with the storage space 124 between the upper end opening of the measuring unit 161 in the pipe unit 193 and the lower end of the pipe unit 13. Positioned to be formed. The recess forming portion 191 and the bottom wall portion 192 may be integrally formed with each other.

The above-mentioned fixed-quantity pouring container is assembled as follows and filled with a liquid. That is, while the pipe portion 13 is inserted and fixed from the mouth portion 121 of the container body 12, the head portion 163 of the shaft portion 162 of the measuring member 16 is pushed into the inner cylinder portion 172 of the elevating operation member 17 from below to perform the elevating operation. The member 17 and the shaft portion 162 are connected to each other. After the elevating and lowering actuating member 17 and the shaft portion 162 in the connected state are inserted into the pipe portion 13 from above and the convex portions 171 and 171 of the outer cylinder portion 172 of the elevating and lowering operating member 17 are fitted into the guide grooves 127 and 127. By twisting and rotating to the end, the inner cylinder portion 173 is slid and arranged in the large diameter portion 133 of the pipe portion 13 in the twisting turning direction. Next, the nozzle member 14 is placed over the elevating and lowering actuating member 17, and the locking projection 141 is engaged with the locking convex edge 126 of the container body 12. At that time, the vertical rib 146 of the nozzle member 14 is inserted into the vertical concave groove 175 of the elevating operation member 17 from above.

Further, the cap 18 is put on the nozzle member 14. At that time, the convex portion 181 of the cap 18 is fitted into the guide groove 128 of the container body 12, the vertical rib 182 is inserted into the vertical concave groove 147 of the cover portion 145 from above, and then the cap 18 is inserted into the guide groove 128. The cap is closed by twisting and rotating to the end of. Then, in a state where the top and bottom are reversed, the measuring portion 161 is fixed by engaging with the lower end of the shaft portion 162 of the measuring member 16 from the lower end opening 122 side of the container main body 12. With the top and bottom reversed, fill the storage space 124 with a predetermined amount of liquid such as a chemical solution from the lower end opening 122 of the container body 12, and then insert the bottom lid 19 to close the bottom of the container body 12. If so, the fixed-quantity pouring container can be used.

Next, the elevating operation between the descending state and the ascending state of the elevating operation member 17 and the measuring member 16 accompanying the opening / closing operation of the cap 18, and the elevating operation, the measuring portion 161, the bulging portion 164, and the small diameter cylinder portion are accompanied by this elevating operation. The relationship with the position conversion of 132 will be described in detail together with the usage method.

When the cap 18 is in the closed cap state as shown in FIG. 9, the elevating operation member 17 and the measuring member 16 are in the lowered state, and the bulging portion 164 (see FIG. 13A) is the inner peripheral surface of the small diameter cylinder portion 132. The lead-out space 125 and the storage space 124 are in close contact with each other, and the upper end opening of the measuring unit 161 communicates with the storage space 124, and the inside of the measuring unit 161 is filled with liquid.

From this closed cap state, first, the cap 18 is twisted and rotated around the axis X to open the cap (see the figure at the left end of FIG. 14). Then, the cap 18 rises while rotating because the convex portion 181 slides along the guide groove 128. This rotational force is transmitted to the nozzle member 14 by the vertical rib 182 fitted in the vertical concave groove 147, whereby the nozzle member 14 rotates together with the cap 18. At the same time, as the nozzle member 14 rotates, the rotational force is transmitted to the elevating operating member 17 by the vertical rib 146 fitted in the vertical concave groove 175, whereby the convex portion 171 slides along the guide groove 127. As a result, the elevating actuating member 17 also rises while rotating. As the elevating actuating member 17 rises, the measuring member 16 including the measuring unit 161 also rises at the same time (see the figure in the central portion of FIG. 14). When the measuring portion 161 in the lowered state starts to rise, the upper end opening edge 168 approaches the lower end portion of the pipe portion 13 and comes into close contact with the outer peripheral surface thereof (see FIG. 13 (b)). At this stage, the inside of the measuring unit 161 is cut off from the storage space 124, and the amount of liquid corresponding to the internal volume of the measuring unit 161 is separated from the liquid in the storage space 124, that is, the liquid is weighed.

When the elevating operation member 17 and the measuring member 16 are further raised, the convex portion 181 of the cap 18 is guided to the apex position of the guide groove 128, and the elevating operating member 17 and the measuring member 16 are raised to the raised state (FIG. 14). (Refer to the figure at the right end), while the inner peripheral surface of the upper end opening edge 168 of the measuring portion 161 further slides upward while maintaining a state of being in close contact with the outer peripheral surface of the lower end portion of the pipe portion 13, the small diameter cylinder portion 132 until then. The bulging portion 164, which was in close contact with the inner peripheral surface of the above, will come off above the small diameter tubular portion 132 (see FIG. 13 (c)). As a result, the inside of the measuring section 161 communicates with the lead-out space 125 through the small-diameter tube section 132. In this ascending state, the upper end surface 174 of the elevating operating member 17 rises to a position close to the lower surface of the step portion 144 of the nozzle member 14, even if an inadvertent ascending operating force acts. , The step portion 144 of the nozzle member 14 acts as a stopper, and the upper end surface 174 of the position elevating actuating member 17 abuts on the lower surface of the step portion 144 of the nozzle member 14, so that the movement from the ascending state to the upper side is restricted. ing.

Then, by pulling out the convex portion 181 that has risen to the apex position of the guide groove 128 upward (see the figure on the left side of FIG. 15), the cap 18 is separated from the container body 12, and the container body 12 from which the cap 18 is removed is removed. Turn it upside down and put it in an inverted state. As a result, the liquid measured in the measuring section 161 is led out to the lead-out space 125, and then falls into the middle cylinder section 143 of the nozzle member 14 through the communication hole 165 of the head portion 163. In this inverted state, the plug portion 152 is pressed against the affected part (for example, the scalp) H. As a result, the elastic arm portions 153, ... Of the spring valve 15 are bent, the plug portion 152 is retracted (see also FIG. 12B), and the nozzle hole 140 is opened through the concave groove 155. The liquid reaching the portion 143 is poured into the scalp H through the concave groove 155, and the liquid Q can be applied to the scalp.

After use, the fixed quantity pouring container is returned to the upright state and covered with the cap 18, the vertical rib 182 thereof is fitted into the vertical concave groove 147 of the nozzle member 14, and the convex portion 181 is fitted to the top end of the guide groove 128 of the container body 12. By pushing and turning the cap 18 in accordance with the inlet, the cap 18 twists and rotates in the direction opposite to the opening operation, and returns to the original closed state. As a result, the elevating actuating member 17 and the measuring member 16 also rotate together and return to the descending state.

According to the above-mentioned quantitative injection container, when it is desired to inject a predetermined amount of liquid from the container body 12 in which the liquid is stored, an accurate measurement of the predetermined amount of liquid is simply performed by rotating the closed cap 18 in the opening direction. And, it becomes possible to surely take out (pouring) the weighed liquid. That is, the opening operation of the cap 18 is usually a necessary operation for a container with a cap, and the weighing and pouring can be performed accurately and surely only by performing the opening operation of the cap 18. It will be possible to eliminate the need for other special operations.

Further, a combination of the convex portion 181 and the spiral guide groove 128 is adopted as the elevating operation mechanism of the cap 18, or a combination of the convex portion 171 and the spiral guide groove 127 is adopted as the elevating operation mechanism of the elevating operation member 17. Therefore, as compared with the case of adopting a normal screw connection (for example, screwing with a screw screw), the amount of ascending / descending by the same rotation operation can be significantly increased, and a reliable operation can be obtained by a simple operation.

In addition, when not in use, that is, in the closed cap state in which the cap 18 is put on the container body 12, the measuring member 16 is lowered and the bulging portion 164 is in close contact with the small diameter cylinder portion 132, so that the lead-out space is obtained. The 125 can be isolated from the storage space 124. Further, even in the process of reaching the ascending state of the measuring member 16 or in the ascending state in which the cap 18 is removed, the inner peripheral surface of the upper end opening edge 168 of the measuring unit 161 comes into close contact with the outer peripheral surface of the pipe portion 13 to derive the measurement member 16. The space 125 can be isolated from the storage space 124. As described above, the liquid contained and stored in the container body 12 is sealed regardless of whether it is in the lowered or raised state, or even if the fixed-quantity pouring container is placed in a state such as lying down instead of being upright. The state can be maintained, and the occurrence of liquid leakage or the like can be avoided. Moreover, if the cap 18 is in the open cap state, it has already been converted into a measurable state by the open cap operation, and it looks like it is in a state where a certain amount of liquid can be poured out and applied. The user can grasp it only by itself.

<Third Embodiment>
16 and 17 show a quantitative pouring container according to a third embodiment of the present invention. This fixed quantity pouring container is in line with the second embodiment in its configuration. That is, in the third embodiment, the measuring member 16a provided with the cup-shaped measuring unit 161 moves up and down with respect to the pipe portion 13a, so that the measuring unit 161 measures a predetermined amount of liquid and provides a storage space 124 for the measuring liquid. The point that the measurement liquid can be switched to the lead-out space 125 for separation and removal from the stored liquid, and the opening / closing operation by the twisting rotation of the cap 18 for raising and lowering for that purpose ( It is the same as the second embodiment in the basic technical matters such as the point realized by the opening / closing operation). Hereinafter, the points different from those of the second embodiment will be mainly described in comparison with the second embodiment, and the same components as those of the second embodiment are designated by the same reference numerals as those of the second embodiment and duplicate detailed description is omitted. do.

First, the shaft portion 162a of the measuring member 16a of the third embodiment does not have the bulging portion 164 as in the second embodiment, and is extended to a position near the engaging portion 167 at the lower end thereof with the same outer diameter. There is. At the lower end of the shaft portion 162a, a small diameter shaft portion 169 (connecting shaft) having a small diameter is continuously provided, and subsequently, an engaging portion 167 is continuously provided. On the other hand, instead of the small-diameter tubular portion 132 of the second embodiment, the lower end portion of the pipe portion 13a is slid around the axis X or in the axis X direction with respect to the outer peripheral surface of the lower end portion of the shaft portion 162a. A small diameter opening 132a is formed that is close enough to allow and seal. The small-diameter opening 132a has its inner peripheral edge close to or out of close contact with the outer peripheral surface of the lower end of the shaft portion 162a, so that the opening of the small-diameter opening 132a can be switched to a closed state or an open state. .. The small diameter opening 132a constitutes the "small diameter portion" of the pipe portion 13a, and the shaft portion 162a constitutes the "closed portion".

Next, the nozzle member 14 of the second embodiment is rotatably connected to the container body 12 at a fixed position in the X direction of the axis and does not move up and down, whereas the nozzle member 14a of the third embodiment is The rotation of the cap 18 causes the cap 18 to rotate together, and this rotation also causes the cap 18 to move up and down together with the raising and lowering operating member 17a. That is, as in the second embodiment, the elevating and lowering actuating member 17a has the convex portions 171 and 171 fitted in the guide grooves 127 and 127, and receives the rotational force around the shaft X to elevate and lower. There is. Then, the locking projection 141 is engaged with the lower surface of the convex portions 171, 171 in a state where the lower surface of the step portion 144 of the nozzle member 14a is in contact with the upper end surface 174 of the elevating operation member 17a, and the nozzle member 14a is coupled so as to operate integrally with the elevating actuating member 17a. Therefore, the convex portions 171 and 171 are twisted and rotated along the guide grooves 127 and 127, so that the nozzle member 14a also moves up and down along with the elevating operation member 17a. The elevating actuating member 17a constitutes a "movable member".

The elevating actuating member 17a of the third embodiment rises upward from the outer cylinder portion 172, the inner cylinder portion 173, the donut annular upper end surface 174 connecting the two at the upper end, and the outer peripheral side of the upper end surface 174. The outer cylinder portion 178 and the upper inner cylinder portion 179 rising upward from the inner peripheral side are provided and integrally formed. Then, the upper outer cylinder portion 178 is internally fitted to the inner peripheral surface of the nozzle portion 142 of the nozzle member 14a in a press-fitted state, while the pedestal 151 of the spring valve 15 is externally fitted to the upper inner cylinder portion 179 in a press-fitted state from above. Has been done. Further, the lower end portion of the inner cylinder portion 173 constitutes the upper end portion of the pipe portion 13a in a state where the head portion 163 of the measuring member 16a is internally fitted and coupled so as not to be relatively movable with respect to the axis X direction. It is press-fitted into the diameter portion 133 so as to be slidable in the axis X direction from above.

As described above, when the cap 18 is rotated around the axis X by the opening cap operation from the time when the cap 18 is closed and the elevating operating member 17a and the measuring member 16a are in the descending state (the left end portion of FIG. 17). (See the figure), the convex portions 181 and 181 are guided along the guide grooves 128 and 128 to ascend, and at that time, the nozzle member is formed by the vertical ribs 182 and 182 internally fitted in the vertical concave grooves 147 and 147. It will be transmitted to 14a. By this rotational force transmission, the nozzle member 14a rotates together with the cap 18, and at the same time, the rotation of the nozzle member 14a is transmitted to the elevating operation member 17a by the vertical ribs 146 and 146 fitted in the vertical concave grooves 175 and 175. It will be. Due to this rotational force transmission, the convex portions 171 and 171 are guided and ascended along the guide grooves 127 and 127, so that the elevating operation member 17a is ascended together with the nozzle member 14a and the measuring member 16a. (See the figure in the center of FIG. 17). Then, when the convex portion 181 of the cap 18 is guided to the top end position of the guide groove 128 and the elevating operating member 17a and the measuring member 16a rise to the raised state (see the figure at the right end portion of FIG. 17), the convex portion 181 is moved upward. The cap 18 can be separated from the container body 12a by pulling it out.

In each process of such ascending operation, the measuring unit 161 exhibits the following state changes. That is, in the descending state, the measuring unit 161 is opened facing the storage space 124, and the inside of the measuring unit 161 is filled with liquid (see the figure at the left end portion of FIG. 17). When the measuring member 16a rises from this lowered state, the upper end opening edge 168 approaches the lower end portion of the pipe portion 13a and comes into close contact with the outer peripheral surface thereof (see the figure in the central portion of FIG. 17). As a result, the inside of the measuring unit 161 is cut off from the storage space 124, and the amount of liquid corresponding to the internal volume of the measuring unit 161 is separated from the liquid in the storage space 124 and weighed.

Then, when the measuring unit 161 further rises to the raised state (see the figure at the right end portion of FIG. 17), the inner peripheral surface of the upper end opening edge 168 of the measuring unit 161 comes into close contact with the lower end outer peripheral surface of the pipe portion 13a. While maintaining the state and further sliding upward, the shaft portion 162a, which had been in close contact with the inner peripheral surface of the small-diameter opening 132a, has come off above the small-diameter opening 132a, and the small-diameter opening 132a has a small diameter. The shaft portion 169 will be located. As a result, the inside of the measuring unit 161 communicates with the lead-out space 125 through the gap between the small-diameter opening 132a and the small-diameter shaft portion 169. Therefore, as described with reference to FIG. 15 of the second embodiment, the cap 18 is removed to invert the container body 12a, and then the plug portion 152 is pressed against the application target (for example, the head). For example, a predetermined amount of liquid weighed by the measuring unit 161 can be poured out.

In the second embodiment, the bottom lid 19 composed of two members of the recess forming portion 191 and the bottom wall portion 192 is used, and in the third embodiment, the bottom lid 19a composed of both of them is used. ..

You can get something similar to. In the case of the configuration without the cap 18, it is possible to detachably fit a protective cover only for shielding and protecting the plug portion 152 protruding from the nozzle hole 140.

Further, in the second embodiment or the third embodiment, the measuring unit 62 of the first embodiment can be adopted instead of the measuring unit 161 thereof. In this case, the small diameter cylinder portion 221 of the first embodiment is formed at the lower end of the pipe portions 13, 13a of the second embodiment or the third embodiment in place of the small diameter cylinder portion 132 or the small diameter opening 132a.
