[0012] The following describes in detail an example of a dropper container 1 according to one embodiment of the present invention, with reference to the drawings.

[0013] In the claims and this specification, "upper" and "lower" refer to the upper and lower parts of the dropper container 1 when it is positioned upright, as shown in Figure 1.

[0014] As shown in Figure 1, the dropper container 1 according to this embodiment has a container body 10, a shoulder cover 20, an inner stopper 30, a dropper part 40, and a mounting cylinder part 50.

[0015] The container body 10 is formed of, for example, a synthetic resin material, and includes a first storage chamber 11 and a second storage chamber 12. More specifically, as shown in Figures 1 and 2, the container body 10 is provided with a cylindrical side wall 10a, a bottom wall 10b that closes the lower end of the side wall 10a, inside the side wall 10a, inside the side wall 10a. A first partition wall 10c having an arcuate cross-section that defines and forms the first storage chamber 11, and is provided inside the side wall 10a opposite to the first partition wall 10c to define the second storage chamber 12 inside the side wall 10a. It integrally has a second partition wall 10d with an arcuate cross-section to be formed. Each of the first storage chamber 11 and the second storage chamber 12 has an elliptical cross-section perpendicular to the axis O, and is open at the upper end of the container body 10.

[0016] A first liquid 2 is stored inside the first storage chamber 11, and a second liquid 3 different from the first liquid 2 is stored inside the second storage chamber 12. The first liquid 2 and the second liquid 3 may be, for example, cosmetics such as cosmetic serums or medicinal liquids.

[0017] It should be noted that as long as the container body 10 includes the first storage chamber 11 and the second storage chamber 12, the shape, size, material and the like thereof can be variously modified. Further, the first liquid 2 and the second liquid 3 are not limited to cosmetics and medicinal liquids, and may be various liquids.

[0018] As shown in Figures 1, 3, 4 and 5, the shoulder cover 20 has a cylindrical mouth portion 21 and a cylindrical fitting cylinder portion 22 corresponding to the side wall 10a of the container body 10. The shoulder cover 20 is attached to the container body 10 by fixing the fitting cylinder portion 22 to the upper end of the side wall 10a of the container body 10 by undercut engagement, and covers the upward-facing opening of the container body 10.

[0019] In the present embodiment, the mouth portion 21 has a cylindrical shape, and an external thread 23 is integrally provided on the outer peripheral surface thereof. In the present embodiment, the external thread 23 is a multi-start thread. In Figures 1, 3, 4 and 5, for convenience, only one external thread 23 is provided with a reference sign. It should be noted that the external thread 23 is not limited to a multi-start thread. Further, instead of the external thread 23, a protrusion for undercut engagement may be provided on the outer peripheral surface of the mouth portion 21.

[0020] The shoulder cover 20 has a partition wall 24 on the lower end side of the opening portion 21, and a first guide cylinder 25 and a second guide cylinder 26 each extending in the vertical direction are provided on the lower surface of the partition wall 24 integrally with the partition wall 24 and arranged side by side with each other. As shown in FIGS. 3 and 4, from the opening on the upper end side of the first guide cylinder 25 to the vicinity of the center in the vertical direction, there is formed a square tubular portion 25a having a rectangular cross-sectional shape perpendicular to the axis O, and between the square tubular portion 25a and the opening on the lower end side, there is formed a cylindrical portion 25b having a circular cross-sectional shape perpendicular to the axis O. On the other hand, the second guide cylinder 26 has a circular cross-sectional shape perpendicular to the axis O over the entire range from the opening on the upper end side to the opening on the lower end side.

[0021] The shoulder cover 20 may also be configured to include a guide wall 27 rising from the partition wall 24 between the first guide cylinder 25 and the second guide cylinder 26. The guide wall 27 protrudes upward beyond the upper ends of the first guide cylinder 25 and the second guide cylinder 26, and divides the interior of the opening portion 21 into the side of the first guide cylinder 25 and the side of the second guide cylinder 26.

[0022] Note that the shoulder cover 20 may also be configured without the guide wall 27.

[0023] As shown in FIG. 1, the inner plug 30 is attached to the opening of the container body 10. The inner plug 30 includes a first pipe portion 31, a second pipe portion 32 and an inner plug body 33 each extending in the vertical direction, and is fixedly held on the container body 10 by clamping the edge of the inner plug body 33 between the upper end of the side wall 10a of the container body 10 and the shoulder cover 20. Note that the inner plug body 33 is integrally provided with a sealing body 33a that abuts against the inner peripheral surface of the container body 10.

[0024] The first pipe section 31 and the second pipe section 32 are arranged side by side with axis O in between. The portion of the first pipe section 31 that protrudes downward from the plug body 33 is located in the first housing chamber 11, thereby connecting the first pipe section 31 to the first housing chamber 11. The portion of the second pipe section 32 that protrudes downward from the plug body 33 is located in the second housing chamber 12, thereby connecting the second pipe section 32 to the second housing chamber 12. On the other hand, the portion of the first pipe section 31 that protrudes upward from the plug body 33 is fitted and fixed to the cylindrical portion 25b of the first guide cylinder 25, and the portion of the second pipe section 32 that protrudes upward from the plug body 33 is fitted and fixed to the lower portion of the second guide cylinder 26.

[0025] Alternatively, annular projections 25c and 26a (see Figure 3) may be provided on the inner circumferential surfaces of the first guide cylinder 25 and the second guide cylinder 26, respectively, and the annular projections 31a and 32a provided on the outer circumferential surfaces of the first pipe section 31 and the second pipe section 32 may be undercut-engaged with the corresponding annular projections 25c and 26a, respectively, thereby fixing and holding the first pipe section 31 and the second pipe section 32 with the first guide cylinder 25 and the second guide cylinder 26.

[0026] In this embodiment, the first pipe section 31 and the second pipe section 32 each have a shape in which the inner diameter gradually decreases from the upper end to the lower end, and the lower end portion has cylindrical sections 31b and 32b with constant outer and inner diameters. A first tube 34 is connected to the cylindrical section 31b, which communicates with the inside of the first pipe section 31 and extends to the vicinity of the bottom wall 10b of the first storage chamber 11, and a second tube 35 is connected to the cylindrical section 32b, which communicates with the inside of the second pipe section 32 and extends to the vicinity of the bottom wall 10b of the second storage chamber 12.

[0027] The portion of the first pipe section 31 from the upper end up to a predetermined range is a rectangular tube section 31c, with a rectangular cross-section perpendicular to the axis O. In other words, the upper end opening of the first pipe section 31 has a rectangular cross-section perpendicular to the axis O as its first shape. The rectangular tube section 31c is fitted into the rectangular tube section 25a of the first guide tube 25. Furthermore, the portion of the first pipe section 31 below the rectangular tube section 31c has a circular cross-section perpendicular to the axis O, and is fitted into the cylindrical section 25b of the first guide tube 25 above the inner plug body 33.

[0028] On the other hand, the second pipe section 32 has a circular cross-section perpendicular to the axis O throughout its entire length from the upper end to the lower end; that is, the upper end opening of the second pipe section 32 has a circular cross-section perpendicular to the axis O, which is a second shape different from the first shape. The second pipe section 32 is fitted into the second guide cylinder 26 in the portion above the inner plug body 33.

[0029] As shown in Figure 1, the dropper section 40 has an operating section 41, a partition wall 42, a first dropper tube 43, and a second dropper tube 44. In this embodiment, the partition wall 42, the first dropper tube 43, and the second dropper tube 44 are integrally formed from a synthetic resin material to constitute the dropper body 45 shown in Figures 6 and 7.

[0030] As shown in Figure 1, the operating section 41 is made of an elastically deformable material such as synthetic rubber and is formed in a bag-like shape (approximately dome-shaped) that is convex upwards and open at the bottom. The operating section 41 can be elastically deformed to reduce its internal volume when pressed by the user. A flange-like portion 41a is integrally provided at the lower end of the operating section 41. The operating section 41 is positioned outside the opening 21 of the shoulder cover 20, with the flange-like portion 41a in full contact with the upper end of the opening 21 of the shoulder cover 20 at the sealing member 60 provided on its lower surface.

[0031] The dropper body 45 has a circular base plate portion 45a that is fitted and fixed to the inner circumferential surface of an assembly cylinder portion 41d provided on the upper part of the flange-shaped portion 41a of the operating portion 41. As shown in Figures 1, 7, and 8, the partition wall 42 is integrally provided on the upper surface of the base plate portion 45a and is positioned inside the operating portion 41, protruding upward from the base plate portion 45a. A groove portion 41e is provided on the inner surface of the operating portion 41, and the outer circumferential edge portion of the partition wall 42 engages with the groove portion 41e. As a result, the partition wall 42 divides the inside of the operating portion 41 into a first chamber 41b and a second chamber 41c.

[0032] The first dropper tube 43 and the second dropper tube 44 are integrally connected to the lower surface of the base plate portion 45a and extend downward from the base plate portion 45a. The first dropper tube 43 and the second dropper tube 44 are provided side by side with the axis O in between. The upper end opening of the first dropper tube 43 communicates with the first chamber 41b of the operating section 41, and the upper end opening of the second dropper tube 44 communicates with the second chamber 41c of the operating section 41.

[0033] The guide wall 27 provided on the shoulder cover 20 is positioned between the first dropper tube 43 and the second dropper tube 44.

[0034] The lower end portion of the first dropper tube 43 has a tapered shape corresponding to the first pipe section 31 and is inserted into the first pipe section 31. The lower end of the first dropper tube 43 abuts against the step at the boundary between the first pipe section 31 and the cylindrical section 31b. The lower end opening of the first dropper tube 43 communicates with the first storage chamber 11 of the container body 10 through the first tube 34.

[0035] Furthermore, an annular sealing projection 31e may be provided on the inner circumferential surface of the first pipe section 31, which abuts against the outer circumferential surface of the lower end of the first dropper tube 43.

[0036] The upper portion 43a of the first dropper tube 43, which is the part inserted into the upper end of the first pipe portion 31, that is, the portion corresponding to the rectangular tube portion 31c, has a rectangular cross-section corresponding to the upper end opening of the first shape of the first pipe portion 31. On the other hand, the lower portion 43b of the first dropper tube 43, which is below the upper portion 43a, has a circular cross-section corresponding to the cylindrical portion 31d of the first pipe portion 31. That is, the cross-section of the upper portion 43a perpendicular to the axis O is a rectangular shape corresponding to the rectangular tube portion 31c, and the cross-section of the lower portion 43b perpendicular to the axis O is a circular shape corresponding to the cylindrical portion 31d. Note that the upper portion 43a of the first dropper tube 43 does not have to be exactly the same shape as the upper end opening or rectangular tube portion 31c of the first pipe portion 31, as long as it can engage with the upper end opening or rectangular tube portion 31c of the first pipe portion 31 but cannot engage with the upper end opening or cylindrical portion 31d which has a circular cross-section. In this embodiment, the cross-sectional shape of the upper portion 43a of the first dropper tube 43 is rectangular overall, but one side facing radially outward is arc-shaped, whereas the cross-sectional shape of the upper end opening or rectangular tube portion 31c of the first pipe portion 31 is approximately square.

[0037] The lower end portion of the second dropper tube 44 has a tapered shape corresponding to the second pipe section 32 and is inserted into the second pipe section 32. The lower end of the second dropper tube 44 abuts against the step at the boundary between the second pipe section 32 and the cylindrical section 32b. The lower end opening of the second dropper tube 44 communicates with the second storage chamber 12 of the container body 10 through the second tube 35.

[0038] Furthermore, an annular sealing projection 32c may be provided on the inner circumferential surface of the second pipe section 32, which abuts against the outer circumferential surface of the lower end of the second dropper tube 44.

[0039] The portion of the second dropper tube 44 that is inserted into the upper end of the second pipe section 32 has a circular cross-sectional shape corresponding to the upper end opening of the second shape of the second pipe section 32. Furthermore, the portion of the second dropper tube 44 that is inserted below the upper end of the second pipe section 32 also has a circular cross-sectional shape corresponding to the second pipe section 32. In other words, the entire second dropper tube 44, from its upper end to its lower end, has a circular cross-sectional shape corresponding to the second pipe section 32.

[0040] The mounting cylinder portion 50 is cylindrical with an internal thread 51 on its inner circumference, and is attached to the assembly cylinder portion 41d of the dropper portion 40 by an annular mounting portion 52 provided on the inner circumference at its upper end. In this embodiment, the mounting cylinder portion 50 is attached to the dropper portion 40 so as to be rotatable relative to the dropper portion 40 about axis O, by the mounting portion 52 slidably engaging with an annular groove 41f provided on the assembly cylinder portion 41d.

[0041] The female thread 51 is a multi-start thread that corresponds to the male thread 23 provided in the opening 21 of the shoulder cover 20. The mounting cylinder 50 is detachably attached to the opening 21 by the female thread 51 being screw-connected to the male thread 23. That is, the mounting cylinder 50 is configured to detach from the opening 21 by rotating relative to the opening 21. At this time, the mounting portion 52 slides against the annular groove 41f of the assembly cylinder 41d, so that the dropper body 45 does not rotate relative to the opening 21, and only the mounting cylinder 50 rotates relative to the opening 21.

[0042] Furthermore, if the opening 21 is provided with a projection for undercut engagement instead of a male screw 23, the mounting cylinder 50 is also provided with a projection for undercut engagement instead of a female screw 51. In this case as well, it is preferable that the mounting cylinder 50 is configured to detach from the opening 21 by rotating the mounting cylinder 50 about the axis O, thereby releasing the engagement of the projection for undercut engagement.

[0043] When the mounting cylinder portion 50 is attached to the mouth portion 21, the flange-shaped portion 41a of the operating portion 41 abuts against the upper end of the mouth portion 21 all around via the sealing member 60, and the lower ends of the first dropper tube 43 and the second dropper tube 44 abut against the stepped portion of the first pipe portion 31 to the second pipe portion 32, so that the mouth portion 21 of the container body 10 or shoulder cover 20 is closed. On the other hand, since the mounting cylinder portion 50 is attached to the dropper portion 40, when the mounting cylinder portion 50 is removed from the mouth portion 21, the dropper portion 40 is also removed from the mouth portion 21 together with the mounting cylinder portion 50, and the container body 10 or mouth portion 21 is opened. In other words, the dropper container 1 has a dropper-equipped cap 70 consisting of a mounting cylinder portion 50 and a dropper portion 40, and a container body 80 consisting of a container body 10, a shoulder cover 20 and an inner stopper 30, and the dropper-equipped cap 70 is configured to be detachable from the container body 80.

[0044] In the dropper container 1 according to this embodiment having the above configuration, with the dropper cap 70 attached to the container body 80, pressing the operating part 41 and then releasing the pressure to restore the operating part 41 to its original shape creates a negative pressure in the first chamber 41b of the operating part 41, allowing a predetermined amount of the first liquid 2 contained in the first storage chamber 11 of the container body 10 to be drawn into the first dropper tube 43 through the first tube 34. Simultaneously, creating a negative pressure in the second chamber 41c of the operating part 41 allows a predetermined amount of the second liquid 3 contained in the second storage chamber 12 of the container body 10 to be drawn into the second dropper tube 44 through the second tube 35. In other words, by operating one operating part 41, the first liquid 2 and the second liquid 3 can be simultaneously drawn into the first dropper tube 43 and the second dropper tube 44.

[0045] Then, as shown in Figure 8, with the first liquid 2 drawn into the first dropper tube 43 and the second liquid 3 drawn into the second dropper tube 44, the mounting cylinder portion 50 is rotated to release its engagement with the mouth portion 21, the dropper cap 70 is removed from the container body 80, and the operating portion 41 is pressed towards the desired discharge target with the tips of the first dropper tube 43 and the second dropper tube 44. This pressurizes the first chamber 41b, causing the first liquid 2 to be discharged from the tip of the first dropper tube 43 towards the desired discharge target, and also pressurizes the second chamber 41c, causing the second liquid 3 to be discharged from the tip of the second dropper tube 44 towards the desired discharge target. In other words, by operating a single operating portion 41, the first liquid 2 and the second liquid 3 can be discharged simultaneously from inside the first dropper tube 43 and the second dropper tube 44.

[0046] After use, the first dropper tube 43 is inserted into the first pipe section 31 through the first guide tube 25, and the second dropper tube 44 is inserted into the second pipe section 32 through the second guide tube 26, and the mounting tube 50 is attached to the opening 21, thereby allowing the dropper-equipped cap 70 to be attached to the container body 80 as shown in Figure 1.

[0047] In this configuration, the upper end opening of the first pipe section 31 is rectangular in cross-section, the upper end opening of the second pipe section 32 is circular in cross-section, the portion of the first dropper tube 43 that is inserted into the upper end of the first pipe section 31 is rectangular in cross-section corresponding to the upper end opening of the first pipe section 31, and the portion of the second dropper tube 44 that is inserted into the upper end of the second pipe section 32 is circular in cross-section corresponding to the upper end opening of the second pipe section 32. This prevents the first dropper tube 43 from being mistakenly inserted into the second pipe section 32, thereby preventing the first dropper tube 43 to the second dropper tube 44 from being mistakenly inserted into the second pipe section 32 to the first pipe section 31.

[0048] Furthermore, as described above, the first dropper tube 43 to the second dropper tube 44 are prevented from being mistakenly inserted into the second pipe section 32 to the first pipe section 31. This prevents the first liquid 2 to the second liquid 3 that adheres to the first dropper tube 43 to the second dropper tube 44 when they are mistakenly inserted into the second pipe section 32 to the first pipe section 31 from mixing with the second liquid 3 contained in the second storage chamber 12 or the first liquid 2 contained in the first storage chamber 11. In addition, since the inside of the operating section 41 is divided by a partition wall 42 into a first chamber 41b that communicates with the first dropper tube 43 and a second chamber 41c that communicates with the second dropper tube 44, it is also possible to prevent the first liquid 2 and the second liquid 3 from mixing through the operating section 41.

[0049] Furthermore, since the first dropper tube 43 and the first pipe section 31 to the second dropper tube 44 and the second pipe section 32 each have a tapered shape that narrows downwards, it is possible to easily insert the first dropper tube 43 and the second dropper tube 44 into the first pipe section 31 to the second pipe section 32, respectively, after use.

[0050] Furthermore, since the shoulder cover 20 is provided with a guide wall 27 positioned between the first dropper tube 43 and the second dropper tube 44, when inserting the first dropper tube 43 and the second dropper tube 44 into the first pipe section 31 or the second pipe section 32, respectively, the guide wall 27 guides the insertion positions of the first dropper tube 43 and the second dropper tube 44, making the insertion process easier.

[0051] Furthermore, when the dropper cap 70 is attached to the container body 80, the first dropper tube 43 is inserted into the first pipe section 31 and is not immersed in the first liquid 2 inside the first storage chamber 11, and the second dropper tube 44 is inserted into the second pipe section 32 and is not immersed in the second liquid 3 inside the second storage chamber 12. As a result, even if the first liquid 2 or the second liquid 3 is a liquid with a relatively high viscosity, it is not necessary to provide a scraping member to scrape off the first liquid 2 or the second liquid 3 adhering to the first dropper tube 43 or the second dropper tube 44, thereby reducing liquid accumulation and resistance when attaching or detaching the dropper cap 70.

[0052] The present invention is not limited to the embodiments described above, and it goes without saying that various modifications are possible without departing from the spirit of the invention.

[0053] In the above embodiment, the first shape of the upper end opening of the first pipe section 31 is a rectangular cross-section, and the portion of the first dropper tube 43 that is inserted into the upper end opening of the first pipe section 31 is also a rectangular cross-section, and the second shape of the upper end opening of the second pipe section 32 is a circular cross-section, and the portion of the second dropper tube 44 that is inserted into the upper end opening of the second pipe section 32 is also a circular cross-section. However, the first and second shapes can be changed in various ways as long as the upper end portion of the first dropper tube 43 cannot be inserted into the second pipe section 32.
