An annular top portion 42 extending inward in the radial direction is integrally provided at the upper end of the mounting cylinder portion 41.

The suction member 31 has a climax cylindrical operating portion 31a that can be elastically deformed and restored and deformed in response to an operation from the outside. The operation unit 31a is made of a soft material such as rubber or elastomer. The operation unit 31a has a configuration in which a cylindrical peripheral wall is integrally hung on the outer peripheral edge of a dome-shaped top wall protruding upward. An annular upper flange 31b extending radially outward is integrally provided at the lower end of the operation portion 31a. Further, an outer peripheral convex portion 31c that projects radially outward over the entire circumference is integrally provided at the lower portion of the outer peripheral surface of the peripheral wall of the operation portion 31a. An inner peripheral convex portion 42a projecting inward in the radial direction is integrally provided on the inner peripheral edge of the annular top portion 42, and the inner peripheral convex portion 42a is fitted between the outer peripheral convex portion 31c and the upper flange 31b. As a result, the suction member 31 is held by the mounting member 40 in a state where the upper flange 31b is arranged below the annular top portion 42.

The holding member 32 has a cylindrical tubular portion 32a and an intermediate flange 32b that protrudes radially outward from the axial intermediate portion of the tubular portion 32a. The intermediate flange 32b is arranged along the lower surface of the upper flange 31b. A holding convex portion 32c is provided on the upper portion of the outer peripheral surface of the tubular portion 32a. The holding convex portion 32c is engaged with a concave portion 31d provided on the inner peripheral surface of the peripheral wall of the operating portion 31a, whereby the axial displacement of the holding member 32 with respect to the suction member 31 is suppressed. Further, the lower portion of the suction member 31 is supported from the inside in the radial direction by the holding member 32, and the deformation in the radial direction is suppressed. The holding member 32 is made of synthetic resin and is less likely to be deformed than the soft suction member 31. By mounting the holding member 32 on the mounting member 40 together with the suction member 31 in advance, it becomes easy to mount the nozzle member 33 on the mounting member 40. That is, the holding member 32 can improve the settability of the nozzle member 33 with respect to the mounting member 40.

As shown in FIGS. 1 and 2, the nozzle member 33 has a tubular nozzle portion 33a whose lower portion is reduced in diameter downward (circular tubular in this example). An annular lower flange 33b extending radially outward is integrally provided on the upper portion of the nozzle portion 33a. The lower flange 33b is held along the lower surface of the intermediate flange 32b of the holding member 32 by undercut engagement on the inner peripheral surface of the mounting cylinder portion 41 of the mounting member 40. Further, a convex portion 33c protruding upward is provided on the outer peripheral edge portion of the lower flange 33b, and the convex portion 33c is on the outer peripheral side of the intermediate flange 32b and on the lower surface of the upper flange 31b of the suction member 31. Contact. Further, the upper portion of the nozzle member 33 is supported from the inside in the radial direction by the holding member 32, and the deformation in the radial direction is suppressed.

A tip opening 33d is provided at the lower end of the nozzle member 33, that is, at the lower end of the nozzle 33a. The tip opening 33d communicates with the first space S1 inside the dropper 30. In FIG. 3, the plug body 34 is in the closed position and closes the tip opening 33d. As a result, the outflow of the first agent contained in the first space S1 is suppressed. The plug 34 opens the tip opening 33d by moving to an open position (see FIG. 7) above the closed position. That is, the plug body 34 can move in the axial direction (direction along the axis O) of the nozzle portion 33a between the closed position for closing the tip opening 33d and the open position for opening the tip opening 33d. .. In this example, the plug 34 is spherical, but the plug body 34 is not limited to this, and can be appropriately changed according to the shape of the tip opening 33d.

Further, an upper protrusion 33e and a lower protrusion 33f are provided on the inner peripheral surface of the lower portion of the nozzle portion 33a. The upper protrusion 33e is a rib-shaped protrusion provided on a part of the inner peripheral surface of the nozzle portion 33a in the circumferential direction. The upper protrusion 33e suppresses the movement of the plug 34 below the upper protrusion 33e again after the plug 34 moves above the upper protrusion 33e. As a result, it is possible to prevent the plug body 34, which has once moved to the open position, from moving to the closed position again and closing the tip opening 33d. The upper protrusion 33e may be provided at only one place in the circumferential direction, or may be provided at a plurality of places. Further, the lower protrusion 33f is an annular protrusion that extends below the upper protrusion 33e and extends over the entire circumference of the inner peripheral surface of the nozzle portion 33a. The lower protrusion 33f prevents the plug 34 from coming out of the nozzle portion 33a. Further, the lower protrusion 33f abuts on the outer peripheral surface of the plug body 34, so that the closing effect (sealing performance) of the tip opening 33d by the plug body 34 can be enhanced. Further, the lower protrusion 33f abuts on the outer peripheral surface of the protrusion 13f, so that the closing effect (sealing) of the tip opening 33d by the protrusion 13f can be enhanced.

Further, the tip portion (lower end portion) of the nozzle portion 33a has a double wall structure having an inner peripheral wall 33g and an outer peripheral wall 33h, and the lower end opening of the inner peripheral wall 33g is the tip opening 33d of the nozzle portion 33a. It has become. The plug body 34 closes (seals) the tip opening 33d of the nozzle portion 33a by abutting the outer surface of the plug body 34 on the inner peripheral surface of the inner peripheral wall 33g at the closed position. The outer peripheral wall 33h is connected to the inner peripheral wall 33g at the upper end thereof, and the lower side of the outer peripheral wall 33h is arranged at a predetermined interval from the outer peripheral surface of the inner peripheral wall 33g. In this example, the inner peripheral wall 33g projects below the outer peripheral wall 33h. This makes it easier to see the lower end of the inner peripheral wall 33g from the outside. Therefore, when dropping the mixed content using the dropper 30, while checking the position of the tip of the nozzle portion 33a (lower end of the inner peripheral wall 33g). The contents can be reliably dropped on the desired location.

Further, in this example, the outer peripheral surface of the outer peripheral wall 33h is spherical, and the lower portion thereof is tapered downward. According to this, when the cap 20 is attached to the container body 10, the outer peripheral wall 33h is easily guided to the inside of the storage cylinder portion 13d of the bottom portion 13. As a result, when the cap 20 is attached to the container body 10, the protrusion 13f can be more smoothly inserted into the tip opening 33d of the nozzle portion 33a. In the set state shown in FIG. 1, the tip opening 33d of the nozzle portion 33a is closed by the protrusion 13f.

An annular plate-shaped packing 35 is arranged below the lower flange 33b of the nozzle member 33. The packing 35 is held on the outer peripheral surface of the nozzle portion 33a by undercut engagement in a state where the upper surface of the packing 35 is in contact with the lower surface of the lower flange 33b.

The mounting member 40, the holding member 32, and the nozzle member 33 are each made of synthetic resin, but the present invention is not limited to this.

The method of setting the dropper container 1 will be described below. First, before setting the cap 20 on the container body 10, the inside of the container body 10 (second space S2) is filled with the second agent as shown in FIG. 2, and the dropper 30 of the cap 20 is filled as shown in FIG. The inside of the (first space S1) is filled with the first agent.

Here, as a method of filling the inside of the dropper 30 (first space S1) with the first agent, in a state before the nozzle member 33 is attached to the mounting member 40 (a state in which the nozzle member 33 is removed from the mounting member 40). , The inside of the nozzle member 33 (first space S1) is filled with the first agent. At this time, the tip opening 33d of the nozzle member 33 is closed by the plug 34 in the closed position. Then, the nozzle member 33 containing the first agent is inserted into the mounting member 40 to which the suction member 31 and the holding member 32 are assembled in advance from below. As described above, by mounting the holding member 32 on the mounting member 40 together with the suction member 31, the nozzle member 33 can be easily mounted and the nozzle member 33 is less likely to fall off. As a result, as shown in FIG. 3, the cap 20 is in a state in which the first agent is sealed in the first space S1 inside the dropper 30.

Next, the cap 20 is attached to the container body 10 by inserting the nozzle portion 33a of the cap 20 into the mouth portion 11 of the container body 10 and screwing the mounting member 40 into the mouth portion 11. Here, FIG. 4 shows a state immediately before the attachment of the cap 20 to the container body 10 is completed. Further, FIG. 5 is a partially enlarged cross-sectional view of FIG.

As shown in FIGS. 4 and 5, the tip opening 33d of the nozzle portion 33a is closed by the plug 34 in the closed position until just before the attachment of the cap 20 to the container body 10 is completed. Then, as the cap 20 is attached to the container body 10 (as the attachment member 40 is screwed into the mouth portion 11), the protrusion 13f enters the tip opening 33d. Then, the protrusion 13f that enters the tip opening 33d comes into contact with the plug 34 from below, and gradually pushes the plug 34 into the nozzle portion 33a (pushes it upward). As a result, as shown in FIG. 6, the plug body 34 gets over the upper protrusion 33e. By completely screwing the mounting member 40 into the mouth portion 11, the setting of the cap 20 with respect to the container body 10 is completed. The method of setting the dropper container 1 is not limited to the above method.

Here, FIG. 6 is a partially enlarged cross-sectional view of FIG. 1, showing a set state in which the cap 20 is completely attached to the container body 10. As shown in FIGS. 1 and 6, the plug 34 pushed up by the protrusion 13f moves to the open position, and the tip opening 33d is closed by the protrusion 13f. That is, in the process of setting the cap 20 with respect to the container body 10, the member that closes (seals) the tip opening 33d moves from the plug 34 to the protrusion 13f. As shown in FIG. 6, the outer peripheral surface of the protrusion 13f is in close contact with the inner peripheral surface of the nozzle portion 33a (the inner peripheral surface of the inner peripheral wall 33g). In this example, the lower protrusion 33f is provided on the inner peripheral surface of the nozzle portion 33a so that the inner peripheral surface of the lower protrusion 33f comes into contact with the outer peripheral surface of the protrusion 13f. The sealing performance of 33d can be improved. Since the protrusion 13f closes the tip opening 33d before (or at the same time) the plug 34 moves to the open position, the first space S1 and the second space S2 are set in the process of setting the cap 20 on the container body 10. And do not communicate.

When dropping the mixed contents from the dropper container 1, first, from the set state shown in FIGS. 1 and 6, the mounting member 40 is rotated in the screwing direction, and the protrusion 13f opens at the tip as shown in FIG. The cap 20 is moved upward until it comes out (disengages) from the portion 33d. As a result, the tip opening 33d of the nozzle portion 33a is opened, and the first agent and the second agent can be mixed and used. Then, as shown in FIG. 7, by crushing (elastically deforming) the operating portion 31a, the first agent of the first space S1 passes through the tip opening 33d and moves (delivered) to the second space S2. , The first agent and the second agent are mixed to form a mixed content. As shown in FIG. 7, even in the usable state in which the tip opening 33d is open, the first agent does not flow out from the dropper 30 until the operation portion 31a is crushed. Therefore, before mixing the first agent and the second agent, the dropper 30 is taken out from the container body 10 to check the first agent in the dropper 30 (inside the first space S1), or in the container body 10 (inside the container body 10). It is also possible to confirm the second agent (in the second space S2). Further, for example, by making at least a part of the container body 10 and the nozzle portion 33a transparent or translucent, the first agent in the dropper 30 can be confirmed, or the second agent in the container body 10 can be confirmed. Becomes easier. When both the container body 10 and the nozzle portion 33a are transparent or translucent, the first agent in the dropper 30 can be confirmed without removing the dropper 30 from the container body 10. Further, after the first agent is sent from the first space S1 to the second space S, the cap 20 is attached to the container body 10 again and the dropper container 1 is shaken with the mouth portion 11 closed. Mixing of the agent and the second agent can be promoted.

Then, after the mixed contents are formed inside the container body 10 (second space S2), the mixture can be dropped into a desired position using the dropper 30 of the cap 20. That is, the mixed contents in the container body 10 are elastically deformed and restored and deformed by pressing the operation part 31a with a finger while the tip opening 33d of the nozzle portion 33a is immersed in the mixed contents in the container body 10. An object can be sucked up into the nozzle portion 33a. Then, by removing the cap 20 from the mouth portion 11 and pressing the operation portion 31a again at a desired location to elastically deform the cap 20, the mixed contents can be sent out from the inside of the nozzle portion 33a and dropped.

As described above, the dropper container 1 according to the present embodiment includes a container body 10 having a mouth portion 11, a body portion 12, and a bottom portion 13, and a cap 20 having a dropper 30 and capable of opening and closing the mouth portion 11. The dropper 30 includes a tubular nozzle portion 33a, a plug body 34 capable of closing the tip opening 33d of the nozzle portion 33a, and an operation portion 31a capable of delivering the contents in the nozzle portion 33a in response to an operation from the outside. When the cap 20 is set on the container body 10, the protrusion 13f provided inside the container body 10 pushes the plug 34 toward the inside of the nozzle portion 33a, and the protrusion 13f is at the tip. The opening 33d is closed to enter the set state, and when the cap 20 is pulled up from the container body 10 from the set state, the protrusion 13f is separated from the tip opening 33d and the tip opening 33d is opened to be in a usable state. It is configured as. With such a configuration, in the set state shown in FIGS. 1 and 6, the first agent can be accommodated in the first space S1 and the second agent can be accommodated in the second space S2. That is, two different types of contents (first agent and second agent) can be housed in separate spaces inside the dropper container 1 in an isolated state. Further, at the time of use, the first agent and the second agent can be mixed by pulling up the cap 20 as shown in FIG. 7, and the formed mixed contents are dropped (poured) using the dropper 30. can do.

Therefore, according to the dropper container 1 according to the present embodiment, it is possible to contain the two kinds of contents in an isolated state and drop them in a mixed state at the time of use.

Further, in the dropper container 1 according to the present embodiment, the container main body 10 has a main body member 10a forming the mouth portion 11 and the body portion 12, and a bottom member 10b attached to the main body member 10a to form the bottom portion 13. doing. In this way, by forming the bottom member 10b constituting the bottom portion 13 separately from the main body member 10a and assembling the bottom member 10b, the bottom portion 13 (bottom member 10b) having the protrusions 13f arranged inside the container main body 10 is provided. ) Can be easily formed.

Further, in the dropper container 1 according to the present embodiment, the bottom portion 13 has a storage recess 13g in which the tip end portion of the nozzle portion 33a is arranged in the set state, and the protrusion 13f is provided inside the storage recess 13g. There is. With such a configuration, the position of the nozzle portion 33a with respect to the container body 10 is stable in the set state, and the protrusion 13f can be easily inserted into the tip opening 33d of the nozzle portion 33a. Further, in the usable state of the dropper container 1, the mixed contents accumulated in the accommodating recess 13g can be easily sucked up into the nozzle portion 33a from the tip opening 33d of the nozzle portion 33a.

Further, in the dropper container 1 according to the present embodiment, the bottom portion 13 has an inclined bottom surface (upper surface of the inclined portion 13c) that inclines downward toward the accommodating recess 13g. With such a configuration, when the cap 20 is attached to the container body 10, the tip portion of the nozzle portion 33a is easily guided to the accommodating recess 13g of the bottom portion 13, and the setting operation is facilitated. Further, in the usable state of the dropper container 1, since the mixed contents can be guided to the accommodating recess 13 g, the dropper 30 can easily suck up the mixed contents, and the amount of the mixed contents remaining in the container body 10 can be reduced. ..

Further, in the dropper container 1 according to the present embodiment, the tip of the nozzle portion 33a is a double wall having an inner peripheral wall 33g having a tip opening 33d and an outer peripheral wall 33h located on the outer peripheral side of the inner peripheral wall 33g. It has a structure. With such a configuration, the inner peripheral wall 33 g can be protected from an impact or the like due to contact with the outside. As a result, it is possible to prevent the plug body 34 and the protrusion 13f from reducing the closing effect of the tip opening 33d due to the deformation of the inner peripheral wall 33g, or preventing the plug body 34 from falling off from the nozzle portion 33a. Can be done.

Further, in the dropper container 1 according to the present embodiment, the inner peripheral surface of the nozzle portion 33a has a lower protrusion 33f that prevents the stopper body 34 from coming out from the tip opening 33d, and a stopper after it becomes usable. An upper protrusion 33e that suppresses the movement of the body 34 to the closed position is provided. With such a configuration, it is possible to prevent the tip opening 33d from being unintentionally blocked by the plug 34 during use, while suppressing the plug 34 from coming out to the outside. Further, when the inner peripheral surface of the annular lower protrusion 33f is in contact with the outer peripheral surface of the protrusion 13f in the set state, the sealing performance of the tip opening 33d by the protrusion 13f can be improved.

Further, in the dropper container 1 according to the present embodiment, the cap 20 is screwed into the mouth portion 11 of the container body 10. With such a configuration, when the cap 20 is set on the container body 10, the nozzle portion 33a can be easily inserted into the container body 10 straight along the axis O. Therefore, the position of the nozzle portion 33a with respect to the container body 10 is stable, and the protrusion portion 13f can be easily inserted into the tip opening portion 33d.

Further, in the dropper container 1 according to the present embodiment, the protrusion 13f is cylindrical. With such a configuration, it is not necessary to align the protrusion 13f with respect to the tip opening 33d in the circumferential direction, so that the work of setting the cap 20 on the container body 10 becomes easier. .. Further, with this configuration, there is no occlusion defect due to the positional deviation between the protrusion 13f and the tip opening 33d in the circumferential direction, so that the sealing performance of the tip opening 33d by the protrusion 13f can be more reliably ensured.

It goes without saying that the present invention is not limited to the above-described embodiment and can be variously modified without departing from the gist thereof. For example, in the above embodiment, the operation portion 31a of the dropper 30 is made of a soft material such as rubber or elastomer, but the present invention is not limited to this, and for example, the cap is urged upward by a spring or the like inside the cap. By pushing down the push button (pressing portion) located at the upper part, the mixed contents may be sucked up or dropped. Further, the operation unit 31a of the above-described embodiment is configured to suck up the mixed contents in the container body 10 into the nozzle unit 33a by elastically deforming and restoring deformation in response to a direct operation from the outside. However, the present invention is not limited to this, and the operating portion 31a is elastically deformed and restored and deformed in response to an indirect operation via an appropriately provided operating member to bring the mixed contents in the container body 10 into the nozzle portion 33a. It may be configured to suck up.

Further, in the above-described embodiment, the tip portion of the nozzle portion 33a has a double wall structure having an inner peripheral wall 33g and an outer peripheral wall 33h, but the present invention is not limited to this, and the nozzle portion 33a may be composed of only the inner peripheral wall 33g.
