Furthermore, a vertical rib 14j extending in the axial direction is provided on the outer circumferential surface of the protrusion 14h. The upper portions of the protrusion 14h and the vertical ribs 14j are configured to taper toward the upper end. The shape, position, etc. of the protrusion 14h are not limited to the illustrated example and can be changed as appropriate.

The fixing member 15 is fixed to the body portion 12 while holding the pressing wall 16c (pressing operation portion) of the pushing member 16 in a pushable manner. The fixing member 15 has a cylindrical peripheral wall 15b that is fixedly held on the trunk body 12b of the trunk 12, and an annular lower wall 15c that extends radially inward from the lower end of the peripheral wall 15b.

The side wall 16a is arranged on the radially outer side of the housing cylinder part 14e, and the pressing wall 16c is located below the bottom wall part 14f. Here, it is preferable that the inner circumferential surface of the side wall 16a abuts at least a part of the outer circumferential surface of the housing cylinder part 14e, and the upper surface of the pressing wall 16c at least partially abuts the lower surface of the bottom wall part 14f. According to this, the pushing member 16 can be positioned with respect to the movable bottom wall 14a, and the postures of the movable bottom wall 14a and the pushing member 16 can be stabilized. The retaining flange 16b is held between the upper surface of the inner peripheral edge of the lower wall portion 15c and the lower surface of the inclined portion 14d of the movable bottom wall 14a. Note that the lower part of the accommodating cylindrical portion 14e is tapered downward, making it easier to insert the accommodating cylindrical portion 14e inside the side wall 16a. In this example, the support wall 15e surrounding the side wall 16a from the outside is configured to easily stabilize the posture of the pushing member 16 that moves up and down.

FIG. 3 shows the cap C alone. The cap C includes a mounting member 40 and a dropper 30. The dropper 30 includes a suction member 31, a holding member 32, a nozzle member 33, and a stopper 34. The nozzle member 33 has a nozzle portion 33a, and the suction member 31 has an operating portion 31a. Therefore, the dropper 30 has a nozzle part 33a and an operating part 31a.

As shown in FIGS. 1 and 2, the mounting member 40 has a cylindrical mounting tube portion 41 that can be attached to and detached from the mouth portion 11. As shown in FIGS. A female threaded portion 41a that can be screwed into the male threaded portion 11a is integrally provided on the inner circumferential surface of the mounting cylinder portion 41. An annular top portion 42 extending radially inward is integrally provided at the upper end of the mounting cylinder portion 41 .

The suction member 31 has a cylindrical capped operation portion 31a that can be elastically deformed and restored in response to an external operation. The operating portion 31a is made of a soft material such as rubber or elastomer. The operating portion 31a has a structure in which a cylindrical peripheral wall is integrally provided vertically on the outer peripheral edge of a dome-shaped top wall that projects upward. An annular upper flange 31b extending radially outward is integrally provided at the lower end of the operating portion 31a. Further, an outer circumferential convex portion 31c that protrudes radially outward over the entire circumference is integrally provided at a lower portion of the outer circumferential surface of the peripheral wall of the operating portion 31a. An inner circumferential protrusion 42a that protrudes radially inward over the entire circumference is integrally provided on the inner circumferential edge of the annular top portion 42, and this inner circumferential protrusion 42a is fitted between the outer circumferential protrusion 31c and the upper flange 31b. As a result, the suction member 31 is held by the mounting member 40 with the upper flange 31b disposed below the annular top portion 42.

The holding member 32 includes a cylindrical tube portion 32a and an intermediate flange 32b that protrudes radially outward from an axially intermediate portion of the tube portion 32a. The intermediate flange 32b is arranged along the lower surface of the upper flange 31b. A holding convex portion 32c is provided at the upper part of the outer circumferential surface of the cylindrical portion 32a. The holding convex portion 32c engages with a recess 31d provided on the inner circumferential surface of the peripheral wall of the operating portion 31a, thereby suppressing axial displacement of the holding member 32 with respect to the suction member 31. Further, the lower portion of the suction member 31 is supported from the inside in the radial direction by the holding member 32, and deformation in the inside in the radial direction is suppressed. The holding member 32 is made of synthetic resin and is less deformable than the soft suction member 31. By attaching the holding member 32 and the suction member 31 to the attachment member 40 in advance, it becomes easier to attach the nozzle member 33 to the attachment member 40. That is, the holding member 32 can improve the ease with which the nozzle member 33 is set to the mounting member 40.

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

A tip opening 33d is provided at the lower end of the nozzle member 33, that is, the lower end of the nozzle portion 33a. The tip opening 33d communicates with the first space S1 inside the dropper 30. In addition, in FIG. 3, the stopper 34 is in the closed position and closes the tip opening 33d. Thereby, outflow of the first agent accommodated in the first space S1 is suppressed. The stopper 34 opens the tip opening 33d by moving to the open position (see FIGS. 4 and 5) above the closed position. That is, the plug body 34 is movable in the axial direction of the nozzle portion 33a between a closed position where the tip opening 33d is closed and an open position where the tip opening 33d is opened.

The plug body 34 has a disk-shaped plate portion 34a and a shaft portion 34b hanging down from the center of the plate portion 34a. A retaining convex portion 34c is provided on the outer peripheral surface of the lower portion of the shaft portion 34b, and a detent convex portion 34d is provided above the retaining convex portion 34c. The retaining convex portion 34c is an annular projection extending over the entire circumference of the shaft portion 34b. The detent convex portion 34d is provided only on a portion of the shaft portion 34b in the circumferential direction. Note that the shape of the plug body 34 is not limited to the illustrated example, and may be, for example, spherical. The retaining convex portion 34c restricts the pushing range of the plug body 34 into the nozzle portion 33a. The detent convex portion 34d prevents the plug body 34 from returning from the open position to the closed position.

Further, on the inner peripheral surface of the lower part of the nozzle part 33a, there is an upward annular support surface 33e that supports the plate part 34a of the stopper 34 in the closed position, and an inward protrusion 33f located below the annular support surface 33e. is provided. The inward protrusion 33f is a protrusion provided on a part of the inner peripheral surface of the nozzle portion 33a in the circumferential direction. The inward protrusion 33f restricts upward movement of the plug body 34 within a predetermined range by engaging with the retaining convex portion 34c (see FIG. 4). Further, the inward protrusion 33f prevents the detent protrusion 34d from moving below the inward protrusion 33f again after the detent protrusion 34d has moved above the inward protrusion 33f. This can prevent the stopper 34, which has once moved to the open position, from moving again to the closed position and blocking the tip opening 33d. Note that the detent convex portion 34d has a smaller protrusion height than the detent convex portion 34c, and when setting the stopper 34 inside the nozzle portion 33a in advance and immediately before use, it is necessary to When the plug 34 is pushed into the nozzle part 33a by the protrusion 14h, the inward protrusion 33f overcomes the detent protrusion 34d. The inward protrusion 33f may be provided at only one location in the circumferential direction of the nozzle portion 33a, or may be provided at multiple locations. The detent convex portion 34d may also be provided at only one location in the circumferential direction of the stopper 34, or may be provided at multiple locations.

When the plug body 34 is in the closed position, the lower surface of the plate portion 34a is supported by the annular support surface 33e, and the outer circumferential surface of the plate portion 34a is in close contact with the inner circumferential surface (sealing surface 33g) of the nozzle portion 33a over the entire circumference. As a result, the tip opening 33d is closed by the stopper 34. The inner diameter of the sealing surface 33g of the nozzle portion 33a, which the outer peripheral surface of the plate portion 34a of the plug body 34 in the closed position abuts, is smaller than the inner diameter of the nozzle portion 33a above the sealing surface 33g. When the plug body 34 is pushed upward from the closed position and the outer peripheral surface of the plate portion 34a is separated from the sealing surface 33g of the nozzle portion 33a, the tip opening portion 33d is opened.

Further, a small diameter cylindrical portion 33h having a smaller diameter than other portions of the nozzle portion 33a is provided at the tip (lower end) of the nozzle portion 33a. The small diameter cylindrical portion 33h surrounds the protrusion 14h from the outside during the pushing operation (the protrusion 14h is inserted inside the small diameter cylindrical portion 33h), thereby suppressing displacement of the protrusion 14h with respect to the plug body 34. do. The inner peripheral surface of the lower end of the small diameter cylindrical portion 33h gradually increases in diameter toward the lower end, making it easier to insert the projection 14h.

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

Note that although the mounting member 40, the holding member 32, the nozzle member 33, and the plug body 34 are each made of synthetic resin, the present invention is not limited thereto.

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

Here, as a method for filling the inside of the dropper 30 (first space S1) with the first agent, the method is to fill the inside of the dropper 30 (first space S1) with the nozzle member 33 before it is attached to the attachment member 40 (with the nozzle member 33 removed from the attachment 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 stopper 34 in the closed position. Then, the nozzle member 33 that accommodates the first agent is inserted from below into the mounting member 40 to which the suction member 31 and the holding member 32 have been assembled in advance. As described above, by mounting the holding member 32 together with the suction member 31 on the mounting member 40, the nozzle member 33 can be easily mounted, and the nozzle member 33 is difficult to fall off. Thereby, the cap C enters a state in which the first agent is sealed in the first space S1 inside the dropper 30, as shown in FIG.

Next, the nozzle part 33a of the cap C is inserted into the mouth part 11 of the container body 10, and the mounting member 40 is screwed into the mouth part 11, thereby attaching the cap C to the container body 10. This completes the setting of the cap C to the container body 10, resulting in the set state shown in FIG. 1. Note that the method for setting the dropper container 1 is not limited to the above method.

When using the dropper container 1, from the set state shown in FIG. 1, as shown in FIG. Perform operations. Due to the pushing operation, the projection 14h of the movable bottom wall 14a moves upward together with the pushing member 16. That is, the movable bottom wall 14a is elastically deformed by the pushing operation, and the protrusion 14h rises along the axis O. The protrusion 14h is gradually inserted into the small diameter cylindrical part 33h, and the upper end of the protrusion 14h comes into contact with the lower end of the plug 34 to push the plug 34 into the nozzle part 33a. Thereby, the stopper 34 moves from the closed position to the open position, and the tip opening 33d is opened. Further, as shown in FIG. 4, the detent convex portion 34d of the plug body 34 overcomes the inward protrusion 33f. When the tip opening 33d of the nozzle portion 33a is opened by moving the stopper 34 from the closed position to the open position, the first agent and the second agent are in a usable state in which they can be mixed. At this time, as shown in FIG. 4, the inclined portion 14d of the movable bottom wall 14a is elastically deformed to generate a restoring force. Then, when the pressing force is released, the movable bottom wall 14a and the pushing member 16 return to their original positions due to restoring deformation of the inclined portion 14d. Here, the detent convex portion 34d of the plug body 34 moves above the inward protrusion 33f due to the above pushing operation, so that the plug body 34 does not return to the closed position. That is, once the pushing operation is performed, the stopper 34 remains in the open position even if the movable bottom wall 14a and the pushing member 16 return to their original positions.

When mixing the first agent and the second agent, the operating portion 31a is crushed (elastically deformed) as shown in FIG. As a result, the first agent in the first space S1 passes through the tip opening 33d and moves to the second space S2, and the first agent and the second agent are mixed to form a mixed content. Incidentally, even if the distal end opening 33d is open for use as shown in FIG. 5, the first agent does not flow out from within the dropper 30 until the operating portion 31a is crushed. Therefore, before mixing the first agent and the second agent, the dropper 30 is pulled out from the container body 10 to check the first agent in the dropper 30 (inside the first space S1), or to check the amount of the first agent in the container body 10 (inside the first space S1). It is also possible to check the second agent in the second space S2). Furthermore, for example, by making at least a portion of the container body 10 and the nozzle part 33a transparent or translucent, it is possible to check the first agent in the dropper 30 and the second agent in the container body 10. 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 delivered from the first space S1 to the second space S, mixing of the first agent and the second agent can be promoted by shaking the dropper container 1.

After the mixed contents are formed inside the container body 10 (second space S2), the mixed contents can be dropped at a desired position using the dropper 30 of the cap C. That is, with the tip opening 33d of the nozzle part 33a immersed in the mixed content in the container body 10, the operating part 31a is pressed with a finger to cause elastic deformation and restoring deformation, thereby changing the mixed content in the container body 10. Objects can be sucked up into the nozzle portion 33a. Then, by removing the cap C from the mouth portion 11 and elastically deforming the operating portion 31a by pressing the operating portion 31a again at a desired location, the mixed contents can be sent out from within the nozzle portion 33a and dripped.

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 C having a dropper 30 and allowing the mouth portion 11 to be opened and closed. The dropper 30 includes a tubular nozzle portion 33a, a stopper 34 capable of closing a tip opening 33d of the nozzle portion 33a, and an operating portion 31a capable of dispensing the contents within the nozzle portion 33a in response to an external operation. The bottom part 13 has an elastically deformable movable bottom wall 14a provided with a protrusion 14h projecting into the interior of the container body 10 (second space S2), and a pressing operation part (pressing wall 16c). ), the protrusion 14h pushes the stopper 34 that closes the tip opening 33d into the nozzle portion 33a, and the tip opening 33d is opened. With such a configuration, in the set state shown in FIG. 1, 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 (the first agent and the second agent) can be housed in separate spaces inside the dropper container 1 in an isolated state. In addition, during use, the first and second agents are released by opening the tip opening 33d by pushing the pressing wall 16c as shown in FIG. 4, and crushing the operating part 31a as shown in FIG. Can be mixed. Further, the formed mixed content can be dropped (poured out) using the dropper 30. Note that since the first and second agents can be mixed while keeping the opening 11 of the container body 10 closed with the cap C, there is no risk of the contents leaking outside during the mixing process. .

Therefore, according to the dropper container 1 according to the present embodiment, it is possible to store two types of contents in a separated state and drop them in a mixed state during use.

Moreover, in the dropper container 1 according to the present embodiment, the movable bottom wall 14a has the accommodation recess 14g in which the tip of the nozzle part 33a is arranged when the projection 14h pushes the stopper 34, and the projection 14h , is provided inside the housing recess 14g. With such a configuration, the position of the nozzle portion 33a with respect to the container body 10 during the pushing operation is stabilized, and the protrusion 14h can be easily inserted into the tip opening 33d of the nozzle portion 33a. In addition, when the dropper container 1 is in a usable state, the mixed contents accumulated in the accommodation recess 14g can be easily sucked up into the nozzle part 33a from the tip opening 33d of the nozzle part 33a. In addition, from the viewpoint of making it easier to insert the protrusion 14h into the tip opening 33d of the nozzle portion 33a, it is recommended that the tip of the nozzle portion 33a enter the accommodation recess 14g in the set state, as shown in FIG. desirable.

Further, in the dropper container 1 according to the present embodiment, the movable bottom wall 14a has a sloped bottom surface (upper surface of the sloped portion 14d) that slopes downward toward the accommodation recess 14g. With such a configuration, the movable bottom wall 14a is easily elastically deformed upward, so that the pushing operation can be performed with a smaller force. Furthermore, when the dropper container 1 is used, the mixed contents can be guided to the storage recess 14g by the inclined bottom surface, making it easier to suck up the mixed contents using the dropper 30, and reducing the amount of mixed contents remaining in the container body 10. can.

Further, in the dropper container 1 according to the present embodiment, the stopper 34 is movable between a closed position where the tip opening 33d is closed and an open position where the tip opening 33d is opened. , has a plate portion 34a whose outer circumferential surface abuts the inner circumferential surface (sealing surface 33g) of the nozzle portion 33a in the closed position, and a shaft portion 34b that hangs down from the plate portion 34a, and a protrusion 14h that connects the stopper 34 to the nozzle. When pushed into the portion 33a, the upper end of the projection 14h comes into contact with the lower end of the shaft portion 34b. By providing such a shaft portion 34b, the axial size (height) of the protrusion 14h can be kept relatively small. As a result, the posture of the protruding portion 14h during the pushing operation becomes easier to stabilize, and the plug body 34 can be pushed in more reliably.

In addition, in the dropper container 1 according to the present embodiment, the shaft portion 34b includes a retaining convex portion 34c provided on the outer peripheral surface of the lower portion of the shaft portion 34b, and a detent convex portion located above the retaining convex portion 34c. 34d, the retaining convex portion 34c restricts the pushing range of the plug body 34 into the nozzle portion 33a, and the detent convex portion 34d suppresses movement of the plug body 34 from the open position to the closed position. is configured to do so. With such a configuration, it is possible to restrict the movement range of the stopper 34 and prevent the tip opening 33d from being unintentionally blocked by the stopper 34 during use.

With such a configuration, it is possible to provide a pressing operation section on the bottom portion 13 that allows a stable pressing operation with a relatively simple configuration. Note that the movable bottom wall 14a exposed from the hole 15a of the fixed member 15 may be directly pushed in without providing the pushing member 16.

Other embodiments of the present invention will be described below. It should be noted that parts having the same basic functions as those in the embodiment described above are denoted by the same reference numerals in the drawings, and explanations thereof will be omitted.

FIG. 6 shows a set state of a two-type mixed dropper container 2 (hereinafter referred to as the dropper container 2) according to another embodiment of the present invention, and FIG. 7 is a partially enlarged view of FIG. 6.

The bottom part 13 of the container body 10 of the dropper container 2 has a rotation operation part (outer rotation member 22) that is rotatable with respect to the body part 12. In addition, in the dropper container 2, the structure of the cap C is the same as that of the dropper container 1 of the embodiment shown above (see FIG. 3).

As shown in FIG. 7, the bottom part 13 includes an annular fixing member 21 fixed to the body part 12, an outer rotating member 22 rotatably held with respect to the fixing member 21, and an inner side of the outer rotating member 22. It has an inner rotating member 23 that is held, a vertically movable member 24 that is held inside the inner rotating member 23 in the radial direction, and an inner bottom member 14 that is held above the vertically movable member 24. The fixed member 21, the outer rotating member 22, the inner rotating member 23, the vertically movable member 24, and the inner bottom member 14 are coaxially arranged around the axis O. Further, the outer rotating member 22 and the inner rotating member 23 are configured to rotate around the axis O.

The fixed member 21 is restrained from rotating relative to the trunk 12, and the vertically movable member 24 is restrained from rotating relative to the fixed member 21. Further, the inner rotating member 23 is restrained from rotating relative to the outer rotating member 22. Thereby, the outer rotating member 22 and the inner rotating member 23 are configured to be rotatable within a predetermined range with respect to the body portion 12, the fixed member 21, and the vertically movable member 24. Note that the inner bottom member 14 is restrained from rotating relative to the trunk 12 and the fixing member 21. Further, the vertically movable member 24 is held so as to be vertically movable with respect to the body portion 12, the fixed member 21, the outer rotating member 22, and the inner rotating member 23. Note that as a configuration for suppressing the rotation of each member, for example, protrusions that engage with each other in the circumferential direction may be provided between each member, but the arrangement of the protrusions is not particularly limited.

The fixing member 21 is fixed to the body 12. The fixing member 21 has a cylindrical peripheral wall 21a that is fixedly held on the trunk body 12b of the trunk 12. A concave small diameter portion 21b in which the outer rotating member 22 is disposed is provided on the outer peripheral surface of the lower portion of the peripheral wall 21a. A vertical groove 21c parallel to the axis O is provided on the inner peripheral surface of the lower part of the peripheral wall 21a. The tip of a guide protrusion 24e, which will be described later, is arranged in the vertical groove 21c. The vertical groove 21c is a structure for suppressing rotation of the vertically movable member 24 with respect to the fixed member 21. The vertical grooves 21c are arranged at two locations in the circumferential direction with the axis O interposed therebetween. The small diameter portion 21b is provided with a suppressing protrusion 21d that suppresses the outer rotating member 22 from falling off from the fixing member 21 by undercutting the inner circumferential surface of the outer rotating member 22.

The inner bottom member 14 is held above the vertically movable member 24. The fixing flange 14c of the inner bottom member 14 is vertically sandwiched between the lower end of the body 12 and the stepped portion of the inner peripheral surface of the fixing member 21. As a result, the inner sole member 14 is fixedly held between the body portion 12 and the fixing member 21. Note that rotation of the inner bottom member 14 in this example with respect to the trunk portion 12 and the fixing member 21 is suppressed.

The outer rotating member 22 is rotatably held relative to the fixed member 21. The outer rotating member 22 has a cylindrical shape with a bottom, and includes an outer cylinder wall 22a disposed at the small diameter portion 21b of the outer rotating member 22, a lower wall part 22b continuous to the lower end of the outer cylinder wall 22a, and a lower wall part 22b. It has a rotation suppressing portion 22c that projects upward from the rotation suppressing portion 22c. The outer cylinder wall 22a constitutes a rotation operation section. The outer peripheral edge of the lower wall portion 22b constitutes a ground plane. The rotation suppressing portion 22c is a convex portion provided on the upper surface of the lower wall portion 22b, and engages with the inner rotating member 23 to suppress rotation of the inner rotating member 23 with respect to the outer rotating member 22.

The inner rotating member 23 has an annular shape and is configured to be held inside the outer rotating member 22 and rotate together with the outer rotating member 22. The inner rotating member 23 has a cylindrical guide wall 23a in which a guide groove 25 shown in FIG. 8 is formed. As shown in FIG. 8, the guide groove 25 has a vertical groove 25a that opens at the upper end of the guide wall 23a and extends in the axial direction, and a lateral groove 25b that extends in the circumferential direction from the lower end of the vertical groove 25a. The vertical groove portion 25a is a groove for introducing a guide protrusion 24e, which will be described later, into the horizontal groove portion 25b, and the guide protrusion 24e is introduced from an opening at the upper end of the guide wall 23a. The lateral groove portion 25b is a groove that engages with the guide protrusion 24e and allows the vertically moving member 24 to move up and down in accordance with the rotational operation of the outer rotating member 22. The lateral groove portion 25b of this example is curved so as to be upwardly convex and extends in a substantially arc shape. Note that the shape of the guide groove 25 is not limited to the illustrated example.

As shown in FIG. 7, a regulating convex portion 23b for suppressing vertical movement with respect to the outer rotating member 22 is provided on the outer circumferential surface of the guide wall 23a. An engaging portion 23c that engages with the rotation suppressing portion 22c is provided on the inner peripheral surface of the guide wall 23a. The guide grooves 25 are equally arranged at two locations in the circumferential direction of the inner rotating member 23 with the axis O interposed therebetween.

The vertically movable member 24 includes a cylindrical side wall 24a disposed on the radially outer side of the housing cylinder portion 14e, a partition wall 24b that closes the lower end of the side wall 24a, and an annular wall extending radially outward from the outer peripheral surface of the side wall 24a. 24c, a guide inner wall 24d extending upward from the outer peripheral edge of the annular wall 24c, and a cylindrical guide protrusion 24e provided on the outer peripheral surface of the guide inner wall 24d.

The upper end surface of the side wall 24a is in contact with the lower surface of the inner peripheral edge of the inclined part 14d of the movable bottom wall 14a, and the inner peripheral surface of the side wall 24a is in contact with the outer peripheral surface of the upper part of the housing cylinder part 14e. Further, the upper surface of the partition wall 24b is in contact with the lower surface of the bottom wall portion 14f. The guide inner wall 24d is arranged radially inside the guide wall 23a.

The guide protrusion 24e passes through the guide groove 25 of the inner rotating member 23, and its tip portion is disposed in the vertical groove 21c of the fixed member 21. That is, the guide protrusion 24e moves along the guide groove 25. Note that since the guide protrusion 24e is prevented from rotating by the vertical groove 21c, the vertically movable member 24 can only move vertically with respect to the fixed member 21 and the body 12.

Here, P1 shown in FIG. 8 indicates the position of the guide protrusion 24e in the set state shown in FIGS. 6 and 7. P2 indicated by a two-dot chain line in FIG. 8 indicates the position of the guide protrusion 24e when the vertically movable member 24 is raised the most by the rotation operation of the outer rotating member 22. At this time, as shown in FIG. 9, the protrusion 14h rises together with the vertically movable member 24, pushing the plug 34 into the nozzle part 33a and opening the tip opening 33d of the nozzle part 33a. Further, P3 indicated by a two-dot chain line in FIG. 8 indicates the position of the guide protrusion 24e when the vertically movable member 24 is lowered again from P2 due to a further rotation operation of the outer rotary member 22. At this time, as shown in FIG. 10, the protrusion 14h also descends together with the vertically movable member 24, and the protrusion 14h returns to the vicinity of the set position shown in FIG. 7, but the stopper 34 is maintained in the open position. . Note that when the guide protrusion 24e reaches the position P3, the guide protrusion 24e comes into contact with the terminal end of the lateral groove portion 25b of the guide groove 25, so that further rotational operation of the outer rotary member 22 is suppressed.

When mixing the first agent and the second agent, the operating portion 31a is crushed (elastically deformed) as shown in FIG. As a result, the first agent in the first space S1 passes through the tip opening 33d and moves to the second space S2, and the first agent and the second agent are mixed to form a mixed content.

After the mixed contents are formed inside the container body 10 (second space S2), the mixed contents can be dropped at a desired position using the dropper 30 of the cap C.

As described above, the dropper container 2 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 C having a dropper 30 and allowing the mouth portion 11 to be opened and closed. The dropper 30 includes a tubular nozzle portion 33a, a stopper 34 capable of closing a tip opening 33d of the nozzle portion 33a, and an operating portion 31a capable of dispensing the contents within the nozzle portion 33a in response to an external operation. The bottom part 13 has an elastically deformable movable bottom wall 14a provided with a protrusion 14h projecting into the interior of the container body 10 (second space S2), and the bottom part 13 has an elastically deformable movable bottom wall 14a that is rotatable with respect to the body part 12. By the rotational operation of the rotary operation part (outer cylinder wall 22a of the outer rotating member 22), the protrusion 14h pushes the stopper 34 that closes the tip opening 33d into the nozzle part 33a, and the tip opening 33d is opened. It is configured to With this configuration, in the set state shown in FIGS. 6 and 7, two different types of contents (first agent and second agent) can be stored in separate spaces inside the dropper container 2 in a separated state. I can do it. In addition, during use, the first agent and the second agent are mixed by rotating the outer rotary member 22 to open the tip opening 33d as shown in FIGS. 9 and 10 and crushing the operating portion 31a. I can do it. Further, the formed mixed content can be dropped (poured out) using the dropper 30.

Therefore, according to the dropper container 2 according to this embodiment, it is possible to store two types of contents in a separated state and drop them in a mixed state during use.

In addition, in the dropper container 2 according to the present embodiment, the bottom portion 13 includes an annular fixing member 21 fixed to the body portion 12 and a bottomed cylinder that is rotatably held with respect to the fixing member 21 and constitutes a rotation operation section. an annular inner rotating member 23 that is held inside the outer rotating member 22 and rotates together with the outer rotating member 22; It has a vertically movable member 24 that moves up and down with rotation, and an inner bottom member 14 that is held above the vertically movable member 24 and forms a movable bottom wall 14a. With such a configuration, it is possible to provide a rotation operation section on the bottom portion 13 that allows stable rotation operation with a relatively simple configuration. Moreover, since the inner rotating member 23 and the vertically movable member 24 are covered from the outside by the fixed member 21 and the outer rotating member 22, malfunctions due to intrusion of dust and the like can be prevented.

Further, in the dropper container 2 according to the present embodiment, the inner rotating member 23 has a cylindrical guide wall 23a and a guide groove 25 formed in the guide wall 23a, and the vertically movable member 24 has a guide groove 25 formed in the guide wall 23a. It has a guide protrusion 24e that moves along. With such a configuration, by adjusting the angle, length, etc. of the guide groove 25, it is possible to easily adjust the vertical movement of the vertically movable member 24 accompanying the rotation of the inner rotating member 23.

Further, in the dropper container 2 according to the present embodiment, the fixing member 21 has a vertical groove 21c for suppressing the rotation of the vertically movable member 24 with respect to the fixing member 21, and the tip of the guide projection 24e passing through the guide groove 25. The structure is such that the portion is arranged in the vertical groove 21c. With such a configuration, the guide protrusion 24e can be used for both the function of vertically moving the vertically movable member 24 as the inner rotating member 23 rotates and the function of suppressing rotation relative to the fixed member 21. Therefore, it becomes possible to further simplify the structure of the dropper container 2.

It goes without saying that the present invention is not limited to the embodiments described above, and can be modified in various ways without departing from the spirit thereof. For example, in the embodiment described above, the operation part 31a of the dropper 30 is made of a soft material such as rubber or elastomer, but the configuration is not limited to this. A configuration may be adopted in which the mixed contents are sucked up or dripped by pressing down a push button (pressing part) located at the top. Further, the operating section 31a of the embodiment described above is configured to suck up the mixed contents in the container body 10 into the nozzle section 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 mixed contents in the container body 10 can be transferred into the nozzle part 33a by elastically deforming and restoring the operating part 31a in response to an indirect operation via an appropriately provided operating member. It may be configured so that it is sucked up.
