Hereinafter, the present invention will be described in more detail with reference to the drawings. In the present specification, the vertical direction means the direction along the axis O which is the central axis of the discharge container, and the "upper" side is the side where the discharge cap 30 is located with respect to the container body 10. The "lower" side is the opposite side (the side where the container body 10 is located with respect to the discharge cap 30).

FIGS. 1 to 3 show a discharge container 1 according to an embodiment (first embodiment) of the present invention. As shown in FIG. 1, the discharge container 1 includes a container body 10, a rotary cap 20, and a discharge cap 30. The discharge container 1 can be used as a container for discharging a mixed liquid in which two types of liquids are mixed. The axis O is the central axis of the discharge container 1 and coincides with the rotation axis of the rotation cap 20.

The container body 10 has a cylindrical mouth portion 11, a tubular body portion 13 connected below the mouth portion 11 via a shoulder portion 12, and a bottom portion 14 that closes the lower end opening of the body portion 13.

The shoulder portion 12 is an annular portion located between the mouth portion 11 and the body portion 13. The shoulder portion 12 of this example extends perpendicularly to the axis O of the container body 10. The shoulder portion 12 is provided with a tubular wall 15 that projects upward from the upper surface of the shoulder portion 12. The outer peripheral surface of the tubular wall 15 is provided with a retaining convex portion 15a and a detenting convex portion 15b protruding outward in the radial direction.

The retaining convex portion 15a engages with the retaining convex portion 25a of the rotating cap 20, which will be described later, to suppress the rise of the rotating cap 20 with respect to the container body 10 within a predetermined range. The detent convex portion 15b is arranged below the retaining convex portion 15a. The detent convex portion 15b engages with the detent convex portion 25a of the rotary cap 20, which will be described later, so that the rotary cap 20 once raised does not return downward. As a result, the communication state between the first accommodation space S1 and the second accommodation space S2 is reliably maintained.

The body portion 13 of this example has a cylindrical shape, and the upper end portion thereof is connected to the outer peripheral edge of the shoulder portion 12. A bottom portion 14 is fitted and held at the lower end portion of the body portion 13. As shown in FIG. 2, an engaging convex portion 13a is provided on the outer peripheral surface of the body portion 13. The engaging convex portion 13a is provided on a small diameter portion 13b formed at the lower end portion of the body portion 13. Since the small diameter portion 13b is formed to be thinner than the other portions of the body portion 13, the diameter of the outer peripheral surface is smaller than that of the other portions.

The bottom portion 14 closes the lower end opening of the body portion 13. The bottom portion 14 has an annular bottom body 16 that fits into the lower end of the body portion 13 and a bottom lid 17 that closes the central opening 16a of the bottom body 16.

In this example, the small diameter portion 13b of the body portion 13 is sandwiched between the outer peripheral wall 16b and the inner peripheral wall 16d to improve the sealing property between the body portion 13 and the bottom body portion 16.

An engaging convex portion 16h is provided on the outer peripheral surface of the cylindrical wall 16f. Further, a holding protrusion 16k is provided on the inner peripheral surface of the cylindrical wall 16f.

The bottom lid 17 is provided on the outer cylinder portion 17a arranged on the outer peripheral side of the cylindrical wall 16f, the closed wall portion 17b connected to the lower end portion of the outer cylinder portion 17a, and the radial inside (inner peripheral side) of the outer cylinder portion 17a. It has a seal cylinder portion 17c protruding upward from the closing wall portion 17b. An engaging convex portion 17d that engages with the engaging convex portion 16h of the cylindrical wall 16f is provided on the inner peripheral surface of the outer cylinder portion 17a. Since the outer cylinder portion 17a suppresses the deformation of the cylindrical wall 16f to the outside in the radial direction, the fitting strength between the cylindrical wall 16f and the fitting cylinder portion 21f is increased, and the rotating cap 20 is formed from the bottom 14 of the container body 10. The inner bottom wall 21c is more difficult to come out. The bottom lid 17 is not an indispensable configuration, and the bottom portion 14 may be configured only by the bottom body 16.

The rotary cap 20 is rotatably attached to the mouth portion 11 of the container body 10. The rotary cap 20 of this example is screwed into the mouth portion 11 and moves in the axial direction (vertical direction) along the axis O as the rotary cap 20 rotates with respect to the container body 10.

The rotary cap 20 has a bottomed tubular inner container portion 21 and a mounting portion 22 provided on the outer peripheral side of the inner container portion 21 and mounted on the mouth portion 11. The mounting portion 22 has an outward flange 23 protruding from the outer peripheral surface of the inner container portion 21, a screw wall 24 and an operation wall 25 hanging from the outward flange 23. The space inside the inner container portion 21 is the first storage space S1, and the space outside the inner container portion 21 inside the container body 10 is the second storage space S2. That is, the inner container portion 21 divides the internal space S of the container main body 10 into two spaces including the first storage space S1 and the second storage space S2.

The inner container portion 21 has a cylindrical inner cylinder wall 21a and an inner bottom wall 21c connected to the lower end portion of the inner cylinder wall 21a via a thin-walled weakening portion 21b.

In the inner container portion 21, a male screw portion 21d is provided on the outer peripheral surface of the upper portion (mounting wall 26) of the inner cylinder wall 21a projecting upward from the outward flange 23. The weakened portion 21b is configured to break when the inner cylinder wall 21a moves upward by rotating the rotary cap 20 in the screwing direction, whereby the inner cylinder wall 21a and the inner bottom wall are at least partially broken. The 21c is separated, and the first accommodation space S1 and the second accommodation space S2 communicate with each other. The inner bottom wall 21c has an inclined portion 21e that inclines downward in the radial direction from the connecting portion to the weakened portion 21b, a fitting cylinder portion 21f that hangs down from the inner peripheral edge of the inclined portion 21e, and a fitting cylinder portion 21f. It has a closing wall 21 g that closes the opening of the.

As shown in FIGS. 1 and 2, the inclined portion 21e is arranged along the inclined wall 16e of the bottom body 16, and the fitting cylinder portion 21f is arranged on the inner peripheral side of the cylindrical wall 16f and the seal cylinder portion 17c. .. The fitting cylinder portion 21f is engaged and held on the inner peripheral side of the cylindrical wall 16f. A protrusion 21h that engages with the holding protrusion 16k is provided on the outer peripheral surface of the fitting cylinder portion 21f.

On the inner peripheral surface of the screw wall 24, a female screw portion 24a screwed to the male screw portion 11a of the mouth portion 11 is provided. The inner peripheral surface of the operation wall 25 is provided with a retaining convex portion 25a that engages with the retaining convex portion 15a of the tubular wall 15 to prevent the rotary cap 20 from moving upward.

The weakened portion 21b may be an annular thin-walled portion extending over the entire circumferential direction (entire circumference) of the inner container portion 21, or may have an intermittent shape in the circumferential direction. Further, the weakened portion 21b is not limited to a shape extending linearly in the circumferential direction in the direction perpendicular to the axis O as in this example, and may have a shape having a curved portion and a bent portion. Further, the position of the weakened portion 21b is not limited to the boundary portion between the inner cylinder wall 21a and the inner bottom wall 21c as shown in the illustrated example, and can be changed as appropriate. For example, the weakening portion 21b may be provided in the intermediate portion of the inner cylinder wall 21a, or may be provided in the inclined portion 21e of the inner bottom wall 21c.

The discharge cap 30 is attached to the rotary cap 20. In the initial state shown in FIG. 1, the discharge cap 30 closes the upper end opening of the inner container portion 21, whereby the first accommodation space S1 is sealed. In the initial state shown in FIG. 1, the second accommodating space S2 is sealed by the rotary cap 20 attached to the mouth portion 11 and the container body 10. The discharge cap 30 is configured so that a mixed solution obtained by mixing the first content liquid and the second content liquid can be discharged from the discharge port 38 of the nozzle head 35.

The discharge cap 30 of this example has a mounting cap 31 mounted on the upper end of the inner cylinder wall 21a of the inner container portion 21, and a discharging tool 32 held by the mounting cap 31.

The mounting cap 31 has a mounting cylinder portion 31a, an inward flange 31b connected to the upper end portion of the mounting cylinder portion 31a, and an upper cylinder portion 31c protruding from the upper surface of the inward flange 31b. On the inner peripheral surface of the mounting cylinder portion 31a, a female screw portion 31d screwed into the male screw portion 21d provided on the rotary cap 20 is provided.

The discharge tool 32 includes a pump portion 33 arranged on the inner peripheral side (first accommodation space S1) of the inner cylinder wall 21a, a stem 34 extending upward from the pump portion 33, and a nozzle connected to the upper end portion of the stem 34. It includes a head 35.

The pump unit 33 sucks up the mixed solution inside the discharge container 1 from the lower end opening of the suction pipe 33c by pushing down the nozzle head 35, and pumps it toward the discharge port 38. The specific configuration of the pump unit 33 is not particularly limited.

The pump portion 33 of this example includes a cylinder portion 33a, a flange portion 33b extending radially outward from the outer peripheral surface of the cylinder portion 33a, and a suction pipe 33c connected to the lower end portion of the cylinder portion 33a. Have. The suction pipe 33c extends to the vicinity of the inner bottom wall 21c of the inner container portion 21. An annular sealing member 36 for improving the sealing property is arranged between the lower surface of the flange portion 33b and the upper end surface of the inner cylinder wall 21a.

The nozzle head 35 is configured to be able to be pushed down along the axis O. The nozzle head 35 has a nozzle 37 extending forward, and a discharge port 38 is provided at the tip of the nozzle 37.

In this example, the overcap 40 is detachably attached to the discharge cap 30. The overcap 40 has a disk-shaped top wall 41 and a peripheral wall 42 hanging from the outer peripheral edge of the top wall 41, and covers the nozzle head 35 from the outside. The overcap 40 is fitted and held in the mounting cap 31 by fitting the peripheral wall 42 to the outer peripheral surface of the mounting cylinder portion 31a.

The usage of the discharge container 1 will be described below. In the initial state shown in FIG. 1, the first accommodation space S1 and the second accommodation space S2 are each sealed. That is, in the initial state, the first accommodation space S1 and the second accommodation space S2 do not communicate with each other.

Then, when the mounting portion 22 (operation wall 25) of the rotating cap 20 is rotated with respect to the container body 10 in the screw-off direction, the rotating cap 20 moves upward along the axis O with respect to the container body 10. At this time, although the inner cylinder wall 21a of the inner container portion 21 moves upward, the inner bottom wall 21c is held by the bottom portion 14 of the container main body 10 and does not move upward. As a result, as the rotary cap 20 rises, the thin-walled weakened portion 21b gradually breaks, and finally, as shown in FIG. 3, the inner cylinder wall 21a and the inner bottom wall 21c are separated. .. Then, when the weakened portion 21b was broken, the first storage space S1 and the second storage space S2 were communicated with each other, and were housed in the first content liquid and the second storage space S2 stored in the first storage space S1. The second content liquid is mixed. Even when the weakened portion 21b is broken, the internal space S of the container body 10 is closed, so that the content liquid does not leak to the outside. Therefore, for example, by vigorously shaking the discharge container 1, it is possible to promote the mixing of the first content liquid and the second content liquid.

Then, as shown in FIG. 3, by pushing down the nozzle head 35 of the discharge container 1 with the overcap 40 removed, a mixed solution in which the first content liquid and the second content liquid are mixed is discharged from the discharge port 38. can do.

As described above, the discharge container 1 of the present embodiment includes a tubular mouth portion 11, a body portion 13 located below the mouth portion 11, and a container body 10 having a bottom portion 14 that closes the lower end opening of the body portion 13. A rotary cap 20 that is rotatably attached to the mouth portion 11 and a discharge cap 30 that is attached to the rotary cap 20 and has a discharge tool 32. The rotary cap 20 is an internal space S of the container body 10. A container having a bottomed tubular inner container portion 21 that divides the inner container portion S1 into a first accommodation space S1 and a second accommodation space S2, and a mounting portion 22 that engages and holds the inner container portion 21 with the mouth portion 11. By rotating the rotary cap 20 with respect to the main body 10 in a predetermined direction, a part of the inner container portion 21 is broken so that the first storage space S1 and the second storage space S2 communicate with each other.

With such a configuration, in the discharge container 1 of the present embodiment, the weakened portion 21b is broken by only the operation of rotating the rotary cap 20 with respect to the container body 10 in the screwing direction, and the first accommodation space S1 And the second accommodation space S2 can be communicated with each other. Therefore, in the process of mixing the two types of content liquids (first content liquid and second content liquid) contained in the discharge container 1, there is no risk of the content liquid spilling or adhering to the hand, and 2 Various types of content liquids can be mixed. Further, since the two types of content liquids can be mixed only by rotating the rotary cap 20 with respect to the container body 10 in the screwing direction, the operation is easy.

Further, in the discharge container 1 of the present embodiment, since the inside of one container body 10 is partitioned by the inner container portion 21 to form the first storage space S1 and the second storage space S2, 2 It is not necessary to prepare two containers for each type of content liquid. Therefore, the efficiency of storage and distribution of the discharge container 1 can be improved as compared with the case of using two types of containers.

Further, in the discharge container 1 of the present embodiment, a push-down pump type is configured such that a pump mechanism acts on the discharge cap 30 by pushing down the nozzle head 35 to discharge the mixed solution from the discharge port 38. By providing the discharge tool 32 of the above, a complicated operation is not required when discharging the mixed solution, and the mixed solution can be easily discharged only by pushing down the nozzle head 35.

In this example, by providing the inclined wall 16e on the bottom 14 of the container body 10 and further providing the inclined portion 21e on the inner bottom wall 21c, the bottom surface of the internal space S of the container body 10 is inclined downward toward the center. I try to do it. Further, in this example, the fitting cylinder portion 21f and the closing wall 21g are formed so that the central portion of the bottom surface of the internal space S is the deepest, and the lower end opening of the suction pipe 33c is the internal space S. It is located near the deepest part of. Therefore, the mixed solution of the discharge container 1 can be easily used up to the end, and the residual amount of the mixed solution after use can be reduced.

An example of a method of assembling the discharge container 1 and filling each content liquid will be described below. First, with the rotary cap 20 attached to the mouth 11 of the container body 10 and the bottom 14 not attached to the lower end of the container body 10, the container body 10 is placed in an inverted position and the lower end opening of the body 13 is opened. The second storage space S2 is filled with the second content liquid. The inverted posture of the container body 10 is a posture in which the mouth portion 11 faces downward and the lower end opening of the body portion 13 faces upward. Then, by attaching the bottom portion 14 to the body portion 13 after filling the second content liquid, the lower end opening of the body portion 13 can be sealed. That is, the second accommodation space S2 is sealed. When the bottom portion 14 is attached to the body portion 13, the bottom portion main body 16 is attached first, and then the bottom lid 17 is attached to the bottom main body 16. When the bottom body 16 is attached to the lower end opening of the body 13, the cylindrical wall 16f of the bottom body 16 is inserted into the outer peripheral side of the fitting cylinder portion 21f of the rotary cap 20, and the holding projection 16k of the cylindrical wall 16f and the fitting cylinder are inserted. The protrusions 21h of the portion 21f slide over each other. Finally, the holding protrusion 16k and the protrusion 21h engage with each other to prevent the fitting cylinder portion 21f from coming off and being held by the cylindrical wall 16f. Then, by attaching the bottom lid 17 so as to cover the cylindrical wall 16f of the bottom body 16 from the outside, the inner bottom wall 21c of the rotary cap 20 is firmly fixed to the bottom 14 of the container body 10.

Next, the container body 10 is inverted to be in an upright posture, and the first content liquid is filled in the first storage space S1 from the upper end opening of the inner container portion 21 of the rotary cap 20 in a state where the discharge cap 30 is not attached. .. Then, the discharge cap 30 is screwed and mounted on the mounting wall 26 of the rotary cap 20, so that the first accommodation space S1 is sealed. The over cap 40 may be attached after the discharge cap 30 is attached to the rotary cap 20, or may be attached to the discharge cap 30 in advance.

In the above method, the second storage space S2 is filled with the second content liquid, and then the first storage space S1 is filled with the first content liquid, but conversely, the posture is upright. After filling the first storage space S1 of the container body 10 with the first content liquid and attaching the discharge cap 30 to the rotary cap 20, the container body 10 is placed in an inverted position and the second content liquid is filled in the second storage space S2. May be filled.

The movable plug member 27 includes a cylindrical tubular portion 28 and a lower wall 29 that closes the lower end portion of the tubular portion 28. A communication hole 28a (opening) is formed in the upper portion of the tubular portion 28, and a male screw portion 28b is provided in the lower portion of the tubular portion 28. Further, on the outer peripheral surface of the tubular portion 28, a rotation suppressing portion 28c for suppressing rotation with respect to the inner tubular wall 21a is provided. In this example, the rotation suppressing portion 28c is composed of a vertical groove into which the vertical rib 21n protruding from the inner peripheral surface of the inner cylinder wall 21a enters, but the shape of the rotation suppressing portion 28c is not limited to this.

The lower wall 29 is composed of an annular elastic portion 29a extending radially inward from the lower end portion of the tubular portion 28 and a central wall 29b connected to the inner peripheral edge of the elastic portion 29a. The elastic portion 29a is formed thinner than the central wall 29b and is elastically deformable.

In the discharge container 3, a bottom wall 16m is provided at the lower end of the cylindrical wall 16f of the bottom body 16. Further, a bottom raising portion 16p is provided in the central portion of the bottom wall 16m. On the inner peripheral surface of the cylindrical wall 16f, a female screw portion 16n that engages with the male screw portion 28b of the movable plug member 27 is provided.

In the initial state shown in FIG. 6, the upper portion of the tubular portion 28 is arranged on the inner peripheral side of the inner cylinder wall 21a, and the communication hole 28a is sealed by the inner peripheral surface of the inner cylinder wall 21a. That is, in the initial state shown in FIG. 6, the lower end opening 21 m of the inner cylinder wall 21a is sealed by the movable plug member 27.

Further, in the initial state shown in FIG. 6, a part of the lower side of the male screw portion 28b of the movable plug member 27 is engaged with the female screw portion 16n of the cylindrical wall 16f. Further, the central wall 29b of the movable plug member 27 is in contact with or close to the bottom raising portion 16p.

When the rotary cap 20 is rotated with respect to the container body 10 from the initial state shown in FIG. 6, the communication hole 28a is opened (the opening of the inner container portion 21 is formed) as shown in FIG. The accommodation space S1 and the second accommodation space S2 communicate with each other. The direction in which the rotary cap 20 is rotated with respect to the container body 10 is the screwing direction (screw-in direction) in which the male screw portion 28b of the movable plug member 27 and the female screw portion 16n of the cylindrical wall 16f are screwed together. By rotating the rotary cap 20 in the screwing direction in this way, the movable plug member 27 is screwed into the cylindrical wall 16f, and the tubular portion 28 moves downward along the axis O. As a result, the central wall 29b of the movable plug member 27 comes into contact with the bottom raising portion 16p, and the elastic portion 29a is brought into the state shown in FIG. 7 with elastic deformation. That is, the lower wall 29, which protrudes downward in the initial state shown in FIG. 6, is inverted so as to be concave upward as shown in FIG. When the lower end of the tubular portion 28 (the outer edge portion of the lower wall 29) comes into contact with the bottom wall 16 m, the rotation in the screwing direction is stopped.

As described above, in the discharge container 3, the rotation cap 20 is rotated in a predetermined direction with respect to the container body 10, so that an opening (communication hole 28a) is formed in the inner container portion 21 to form the first accommodation space S1 and the second. It is configured to communicate with the accommodation space S2.

With such a configuration, in the discharge container 3, the communication hole 28a is opened only by rotating the rotary cap 20 with respect to the container body 10 in the screwing direction, and the first accommodation space S1 and the second accommodation space S2 are opened. Can be communicated with. Therefore, in the process of mixing the two types of content liquid contained in the discharge container 1, there is no risk of the content liquid spilling or adhering to the hand, and the two types of content liquid can be easily mixed. Further, since the two types of content liquids can be mixed only by rotating the rotary cap 20 with respect to the container body 10 in the screwing direction, the operation is easy.

The shape of the communication hole 28a is not particularly limited, but may be, for example, a quadrangular shape shown in FIG. 8A, a circular shape shown in FIG. 8B, a star shape, or the like. As described above, by adopting the shape of the communication hole 28a having high design and making it visible from the outside of the container body 10, the design (aesthetics) of the discharge container can be enhanced. For example, by forming the body 13 of the container body 10 with a transparent or translucent material, the communication hole 28a exposed below the inner cylinder wall 21a can be visually recognized from the outside when the two types of content liquids are mixed. It becomes. Further, when the first inner solution and the second inner solution having different colors are adopted, when the two kinds of content liquids are mixed, the first inner solution is passed through the communication hole 28a from the first accommodation space S1. It is also possible to visually recognize the movement to the second accommodation space S2 side. In this case, the first content liquid preferably has a darker color than the second content liquid. With such a configuration, the shape of the communication hole 28a becomes more conspicuous when the colored first content liquid passes through, and the design can be further enhanced. Further, when the body portion 13 of the container body 10 is made of a transparent or translucent material and the first inner solution and the second inner solution having different colors are adopted, the two types of content liquids are used. The degree of mixing can be easily confirmed from the outside.
