[0016] Embodiments of the present invention will be described with reference to Figures 1 to 19. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant descriptions are omitted. The dimensional ratios in the drawings are exaggerated for illustrative purposes and may differ from actual ratios.

[0017] Figures 1 to 3 show a measuring and dispensing container 1 according to an embodiment of the present invention. Figures 4 to 7 show the cap 20 of the measuring and dispensing container 1 according to this embodiment. Figures 8 to 11 show the first inner cylinder 30 of the measuring and dispensing container 1 according to this embodiment. Figures 12 to 15 show the second inner cylinder 40 of the measuring and dispensing container 1 according to this embodiment. Figures 16 to 19 show the outer cylinder 50 of the measuring and dispensing container 1 according to this embodiment.

[0018] As shown in Figures 1 to 3, the measuring and dispensing container 1 includes a bottle 10 in which the contents liquid such as detergent is stored, a cap 20 screwed onto the mouth 11 of the bottle 10, a first inner cylinder 30 connected to the cap 20, a second inner cylinder 40 provided on the outer circumference of the first inner cylinder 30, and an outer cylinder 50 provided on the outer circumference of the second inner cylinder 40. In the following specification, the horizontal plane is defined as the XY plane, and the vertical direction is defined as the Y direction.

[0019] Bottle 10 contains, for example, a liquid such as detergent. The mouth 11 of bottle 10 is provided with a screw thread 12.

[0020] <Cap 20> As shown in Figure 3, the cap 20 is screwed onto a threaded portion 12 provided on the mouth 11 of the bottle 10 and fixed to the bottle 10. The cap 20 is screwed onto the mouth 11 of the bottle 10 in such a way that it can be removed when rotated counterclockwise when viewed from above in the Z direction.

[0021] As shown in Figures 4 to 7, the cap 20 has a top portion 21 located above in the Z direction, a bottom portion 22 located below in the Z direction, and a connecting portion 23 that connects the top portion 21 and the bottom portion 22.

[0022] A threaded portion 21A is formed on the inner circumferential surface of the top portion 21. The cap 20 is fixed to the bottle 10 by screwing the threaded portion 21A formed on the inner circumferential surface of the top portion 21 with a threaded portion 12 provided on the mouth portion 11 of the bottle 10. When viewed from above in the Z direction, the cap 20 is screwed on so that it can be removed by rotating it counterclockwise relative to the bottle 10.

[0023] As shown in Figures 4 to 7, the outer circumferential surface of the top portion 21 has a protruding convex portion 24 that projects outward. As shown in Figures 4 and 6, the convex portion 24 has a first convex portion 24A formed along the circumferential direction except for a portion, a second convex portion 24B formed downward in the Z direction from the first convex portion 24A, a third convex portion 24C formed along the Y direction from the second convex portion 24B, and a fourth convex portion 24D formed along the Z direction so as to connect the third convex portion 24C and the first convex portion 24A.

[0024] As shown in Figure 6, a flat portion 24H, which is not convex, is formed on a part of the circumferential direction of the first protrusion 24A. As shown in Figure 6, the second protrusion 24B is formed extending downward in the Z direction from a point moved to the left in the Y direction from one end 24E of the first protrusion 24A. The fourth protrusion 24D is formed to be continuous with the other end 24F of the first protrusion 24A. The first protrusion 24A, the second protrusion 24B, and the third protrusion 24C function as engaging portions that engage with the projection 32A of the first inner cylinder 30, which will be described later.

[0025] As will be described later, when measuring the liquid contents with the measuring and dispensing container 1, the outer cylinder 50 is rotated counterclockwise when viewed from above in the Z direction. Because the cap 20 has the convex portion 24 as described above, when the second inner cylinder 40 rotates counterclockwise (one direction of rotation) in conjunction with the rotation of the outer cylinder 50, the protrusion 32A of the first inner cylinder 30, as will be described later, comes into contact with the fourth convex portion 24D.

[0026] For example, if the first inner cylinder is screwed to the cap, and the opening torque between the bottle and the cap is lower than the opening torque between the first inner cylinder and the cap, when the outer cylinder 50 is rotated to measure, there is a risk that the cap 20 will open from the bottle 10 (hereinafter referred to as "co-rotation") before the second inner cylinder 40 moves upward in the Z direction.

[0027] In contrast, in the case of the measuring and dispensing container 1 according to this embodiment, as described above, during measuring, the projection 32A of the first inner cylinder 30 comes into contact with the fourth protrusion 24D of the cap 20, and after measuring, it can be slid upward in the Z direction to remove it. This prevents the cap 20 from rotating together with the container.

[0028] The bottom portion 22 is provided in a hollow cylindrical shape. On the inner circumferential surface of the bottom portion 22, an inwardly convex projection 22A is formed along the circumferential direction. Above the projection 22A, as shown in Figure 3, a valve structure 80 is arranged. This valve structure 80 may be, for example, a ball valve or a slit valve.

[0029] The connecting portion 23 has a tapered shape that expands in diameter upward in the Z direction. As shown in Figures 4 to 6, the connecting portion 23 has four hollow portions 23A in which the inner and outer circumferential surfaces of the connecting portion 23 are in communication.

[0030] <First inner cylinder 30> The first inner cylinder 30 is connected to the cap 20, as shown in Figure 3.

[0031] As shown in Figures 8 to 11, the first inner cylinder 30 has a top portion 31 located above in the Z direction, a bottom portion 32 located below in the Z direction, and an inner circumference portion 33 located on the inner circumference of the top portion 31 and the bottom portion 32.

[0032] The top portion 31 has a hollow shape. The top portion 31 has a concave cam portion 34 provided on its outer circumference.

[0033] As shown in Figures 8 to 11, the cam portion 34 has a first path 34A formed along the inclined direction with respect to the XY plane, a second path 34B formed along the downward direction in the Z direction, continuous with the first path 34A, a third path 34C formed along the XY direction, continuous with the first path 34A and the second path 34B, and a fourth path 34D formed along the Z direction so as to connect the first path 34A and the third path 34C.

[0034] The first path 34A is provided so as to be inclined upwards and to the right when viewed from the front. The first path 34A is configured to be inclined at an angle of approximately 30 degrees with respect to the XY plane, for example, but the angle of inclination is not particularly limited. The first path 34A is formed in a straight line along the direction of inclination. From an intermediate point 35A of the first path 34A, the fourth path 34D is provided along the downward direction. From the end point 35B of the first path 34A, the second path 34B is provided along the downward direction.

[0035] In this embodiment, the fourth path 34D is arranged to connect the center of the first path 34A and the center of the third path 34C.

[0036] As described above, the cam section 34 is configured in such a way that, when the projection 46 of the second inner cylinder 40 passes through the first path 34A and the second path 34B, and when the projection 46 of the second inner cylinder 40 passes through the intermediate point 35A of the first path 34A and the fourth path 34D, different levels of volume can be measured and dispensed.

[0037] The bottom portion 32 has a hollow shape. The inner circumferential surface of the bottom portion 32 is provided with an inwardly convex projection 32A. The projection 32A is circular in shape. As described above, when the second inner cylinder 40 rotates counterclockwise as the outer cylinder 50 rotates, the projection 32A of the first inner cylinder 30 comes into contact with the fourth projection 24D, thereby preventing the cap 20 from rotating together.

[0038] The inner circumference 33 extends from above the top 31 in the Z direction to below the bottom 32 in the Z direction. The inner circumference 33 functions as a path through which the contents move when the measuring and dispensing container 1 measures.

[0039] <Second inner cylinder 40> The second inner cylinder 40 is connected to the first inner cylinder 30, as shown in Figure 3. The second inner cylinder 40 has a planar portion 41 extending in the XY plane and a vertical wall portion 42 rising from the periphery of the planar portion 41, as shown in Figures 12 to 15.

[0040] As shown in Figure 15, the vertical wall portion 42 has a recessed shape in the center and comprises a first vertical wall portion 43 on the outer circumferential surface side and a second vertical wall portion 44 on the inner circumferential surface side.

[0041] The first vertical wall portion 43 has a projection 45 provided on its outer circumferential surface and a projection 46 provided on its inner circumferential surface. The projection 45 is rectangular in shape, and the projection 46 is circular in shape.

[0042] The projection 45 engages with the groove 51A of the outer cylinder 50, which will be described later. As a result, the second inner cylinder 40 rotates along with the rotation of the outer cylinder 50.

[0043] The projection 46 can move along the cam portion 34 described above.

[0044] The second inner cylinder 40 is preferably transparent or translucent, and graduation lines are provided on the outer circumference of the second inner cylinder 40, as shown in Figures 20 and 22. In Figures 20 and 22, graduation lines are provided every 3 mL, but the method is not limited to this.

[0045] <Outer cylinder 50> As shown in Figure 3, the outer cylinder 50 is connected to the second inner cylinder 40.

[0046] As shown in Figures 16 to 19, the outer cylinder 50 has a top portion 51 located above in the Z direction and a bottom portion 52 located below in the Z direction.

[0047] The top portion 51 has a hollow shape. A groove 51A is formed on the inner circumferential surface of the top portion 51. The groove 51A of the top portion 51 engages with the projection 45 of the second inner cylinder 40. As a result, the second inner cylinder 40 rotates in conjunction with the rotation of the outer cylinder 50.

[0048] The outer circumference of the top portion 51 has a convex protrusion 51B that extends in the circumferential direction. The protrusion 51B is the part that the user grips when rotating the outer cylinder 50. For this reason, it is preferable that the protrusion 51B has a rounded shape.

[0049] The top portion 51 is positioned to cover the second inner cylinder 40, as shown in Figure 3. The bottom portion 52 is positioned to cover the bottom portion 32 of the first inner cylinder 30, as shown in Figure 3.

[0050] <Instructions for using the measuring and dispensing container> The configuration of the measuring and dispensing container 1 according to this embodiment has been described above. Next, the method of using the measuring and dispensing container 1 according to this embodiment will be described with reference to Figures 2, 3, 10, and 20 to 23.

[0051] Figures 2 and 3 show the state before use. Figures 20 and 21 show the process of measuring the first level of quantity. Figures 22 and 23 show the process of measuring the second level of quantity. Here, the second level of quantity is approximately half the amount of the first level of quantity.

[0052] First, the user prepares the measuring and dispensing container 1 as shown in Figures 2 and 3. The method of using the device to measure and dispense the first level of volume will be explained below with reference to Figures 20 and 21.

[0053] The user, for example, holds the bottle 10 with their left hand while rotating the outer cylinder 50 counterclockwise with their right hand, viewing it from above in the Z direction. As the outer cylinder 50 rotates counterclockwise, the second inner cylinder 40 connected to the outer cylinder 50 also rotates counterclockwise.

[0054] Then, when the first inner cylinder 30, which is connected to the second inner cylinder 40, rotates slightly counterclockwise, the protrusion 32A of the first inner cylinder 30 comes into contact with the fourth protrusion 24D of the cap 20, and the rotation of the first inner cylinder 30 stops.

[0055] The user then rotates the outer cylinder 50 further, moving the projection 46 of the second inner cylinder 40, which rotates with the outer cylinder 50, along the first path 34A to the endpoint 35B. At this time, as shown in Figures 20 and 21, the second inner cylinder 40 moves upward in the Z direction by a predetermined distance. As a result, the liquid content accumulates in the second inner cylinder 40 and the measurement is completed.

[0056] The user then removes the outer cylinder 50, the second inner cylinder 40, and the first inner cylinder 30 from the bottle 10 and dispenses the measured liquid into, for example, a washing machine. As a result, a first level amount can be measured and dispensed.

[0057] Next, referring to Figures 22 and 23, we will explain how to use the device when measuring and dispensing the second level of quantity.

[0058] The user, for example, holds the bottle 10 with their left hand while rotating the outer cylinder 50 counterclockwise with their right hand, viewing it from above in the Z direction. As the outer cylinder 50 rotates counterclockwise, the second inner cylinder 40 connected to the outer cylinder 50 also rotates counterclockwise.

[0059] Then, when the first inner cylinder 30, which is connected to the second inner cylinder 40, rotates slightly counterclockwise, the protrusion 32A of the first inner cylinder 30 comes into contact with the fourth protrusion 24D of the cap 20, and the rotation of the first inner cylinder 30 stops.

[0060] The user then rotates the outer cylinder 50 further, moving the projection 46 of the second inner cylinder 40, which rotates together with the outer cylinder 50, along the first path 34A to an intermediate point 35A. At this time, as shown in Figures 22 and 23, the second inner cylinder 40 moves upward in the Z direction by half the distance it traveled when measuring the amount at the first level.

[0061] The user then removes the outer cylinder 50, the second inner cylinder 40, and the first inner cylinder 30 from the bottle 10 and dispenses the measured liquid into, for example, a washing machine. As a result, a second level of volume can be measured and dispensed.

[0062] As described above, the measuring and dispensing container 1 according to this embodiment includes a cap 20 screwed onto the mouth 11 of the bottle 10, a first inner cylinder 30 connected to the cap 20, a second inner cylinder 40 provided on the outer circumference of the first inner cylinder 30 and connected to the first inner cylinder 30, and an outer cylinder 50 provided on the outer circumference of the second inner cylinder 40 and connected to the second inner cylinder 40. The first inner cylinder 30 has a concave cam portion 34 provided on its outer circumference. The cam portion 34 includes a first path 34A formed along the inclined direction, a second path 34B formed vertically and continuous with the first path 34A, a third path 34C formed horizontally and continuous with the first path 34A and the second path 34B, and a fourth path 34D formed to connect the intermediate points of the first path 34A and the intermediate points of the third path 34C. The second inner cylinder 40 has a projection 46 provided on its inner circumference, and the projection 46 of the second inner cylinder 40 moves along the cam portion 34. With the measuring and dispensing container 1 configured in this way, the amount measured and dispensed by the projection 46 via the first path 34A, the second path 34B, and the third path 34C is different from the amount measured and dispensed by the projection 46 via the first path 34A, the fourth path 34D, and the third path 34C. From the above, it is possible to provide a measuring and dispensing container 1 that can measure out multiple levels of quantity.

[0063] <Variation> Next, the configuration of the modified measuring and dispensing container 2 will be described with reference to Figures 24 to 29. Figures 24 to 26 show the configuration of the cap 120 of the modified measuring and dispensing container 2. Figures 27 to 29 show the configuration of the first inner cylinder 130 of the modified measuring and dispensing container 2.

[0064] The modified measuring and dispensing container 2 differs from the measuring and dispensing container 1 according to the above-described embodiment in the configuration of the cap 120 and the first inner cylinder 130. Specifically, the modified measuring and dispensing container 2 differs from the measuring and dispensing container 1 according to the above-described embodiment in that it measures by rotating the outer cylinder 50 "clockwise" when viewed from above in the Z direction. Components identical to those in the measuring and dispensing container 1 according to the above-described embodiment are denoted by the same reference numerals, and their descriptions are omitted.

[0065] As shown in Figures 24 to 29, the modified measuring and dispensing container 2 includes a bottle 10 in which the contents liquid such as detergent is stored, a cap 120 screwed onto the mouth 11 of the bottle 10, a first inner cylinder 130 connected to the cap 120, a second inner cylinder 40 provided on the outer circumference of the first inner cylinder 130, and an outer cylinder 50 provided on the outer circumference of the second inner cylinder 40. The configurations of the bottle 10, the second inner cylinder 40, and the outer cylinder 50 are the same as those of the measuring and dispensing container 1 according to the above embodiment, so their explanation is omitted.

[0066] <Cap 120> The cap 120 is screwed onto the mouth 11 of the bottle 10 so that it can be removed when rotated counterclockwise when viewed from above in the Z direction.

[0067] As shown in Figures 24 to 26, the cap 120 has a top portion 121 located above in the Z direction, a bottom portion 122 located below in the Z direction, and a connecting portion 123 that connects the top portion 121 and the bottom portion 122.

[0068] As shown in Figure 26, a threaded portion 121A is formed on the inner circumferential surface of the top portion 121. The cap 20 is fixed to the bottle 10 by screwing the threaded portion 121A formed on the inner circumferential surface of the top portion 121 with a threaded portion 12 provided on the mouth portion 11 of the bottle 10. When viewed from above in the Z direction, the cap 120 is screwed on so that it can be removed by rotating it counterclockwise relative to the bottle 10.

[0069] As shown in Figures 24 and 25, a threaded portion 121B is formed on the outer circumferential surface of the top portion 121. As shown in Figure 25, the threaded portion 121B has a helical shape directed upwards and to the right in a front view. As shown in Figures 24 and 25, the threaded portion 121B of the cap 120 has a convex projection 121C on its outer circumference at its lower end in the Z direction. The projection 121C is circular in shape.

[0070] The bottom portion 122 has the same configuration as the bottom portion 22 of the measuring and dispensing container 1 according to the above-described embodiment, and the connecting portion 123 has the same configuration as the connecting portion 23 of the measuring and dispensing container 1 according to the above-described embodiment.

[0071] <First inner cylinder 130> As shown in Figures 27 to 29, the first inner cylinder 130 has a top portion 131 located above in the Z direction, a bottom portion 132 located below in the Z direction, and an inner circumference portion 133 located on the inner circumference of the top portion 131 and the bottom portion 132.

[0072] The top portion 131 has a hollow shape. The top portion 131 has a concave cam portion 134 provided on its outer circumference.

[0073] As shown in Figures 27 and 28, the cam portion 134 has a first path 134A formed along the inclined direction with respect to the XY plane, a second path 134B formed along the downward direction in the Z direction, which is continuous with the first path 134A, and a third path 134C formed along the XY direction, which is continuous with the first path 134A and the second path 134B.

[0074] The first path 134A is provided so as to be inclined towards the upper left when viewed from the front. The first path 134A is configured to be inclined at approximately 30 degrees with respect to the XY plane, for example, but the inclination angle is not particularly limited. The first path 134A is formed in a straight line along the direction of inclination.

[0075] According to this configuration, in the modified metering and dispensing container 2, when the second inner cylinder 40 is viewed from above in the Z direction, it rotates clockwise (in another direction of rotation), causing the projection 46 of the second inner cylinder 40 to move along the first path 134A of the cam portion 134, thereby performing metering.

[0076] The bottom portion 132 has a hollow shape. A threaded portion 132A is provided on the inner circumferential surface of the bottom portion 132, as shown in Figure 29. The first inner cylinder 130 is fixed to the cap 120 by screwing the threaded portion 132A formed on the inner circumferential surface of the bottom portion 132 with the threaded portion 121B formed on the outer circumferential surface of the cap 120. When viewed from above in the Z direction, the first inner cylinder 130 is screwed onto the cap 120 so that it can be removed by rotating it counterclockwise relative to the cap 120.

[0077] A slit 132S is formed at the lower end of the threaded portion 132A of the bottom portion 132 into which a protruding portion 121C formed at the lower end of the threaded portion 121B of the cap 120 is fitted.

[0078] When closing the outer cylinder 50, second inner cylinder 40, and first inner cylinder 130 after measuring and dispensing the liquid contents, the closing direction is clockwise when viewed from the Z direction. In this case, for example, if there is no protrusion 121C and slit 132S, if the outer cylinder 50, second inner cylinder 40, and first inner cylinder 130 continue to rotate clockwise, there is a possibility that the second inner cylinder 40 may rotate clockwise relative to the first inner cylinder 130 without realizing that the outer cylinder 50, second inner cylinder 40, and first inner cylinder 130 have completely closed, and the measuring process may unintentionally start again.

[0079] In contrast, the modified measuring and dispensing container 2 is provided with a protruding portion 121C and a slit 132S. As the outer cylinder 50, second inner cylinder 40, and first inner cylinder 130 are rotated clockwise to close them, the protruding portion 121C returns to its original position when it passes over the slit 132S, providing a click sensation to the user. Therefore, it is possible to recognize that the outer cylinder 50, second inner cylinder 40, and first inner cylinder 130 are fully closed.

[0080] <Method of using a modified measuring and dispensing container> Next, a modified example of how to use the measuring and dispensing container 2 will be described.

[0081] First, in order to measure, the user holds the bottle 10 with their left hand, for example, and rotates the outer cylinder 50 clockwise with their right hand, viewing it from above in the Z direction. Here, the direction in which the cap 120 detaches from the bottle 10 is counterclockwise when viewed from above in the Z direction, so the rotation of the cap 20 along with the cap can be effectively prevented. As the outer cylinder 50 rotates clockwise, the second inner cylinder 40 connected to the outer cylinder 50 also rotates clockwise.

[0082] The user then moves the projection 46 of the second inner cylinder 40, which rotates together with the outer cylinder 50, along the first path 134A to its end point. As a result, the liquid content accumulates in the second inner cylinder 40, and the metering process is completed.

[0083] The user then rotates the outer cylinder 50, the second inner cylinder 40, and the first inner cylinder 130 counterclockwise while viewing them from above in the Z direction, to remove them from the bottle 10, and dispense the measured liquid into, for example, a washing machine. As a result, the measuring and dispensing process is completed.

[0084] Once metering and dispensing are complete, the user rotates the outer cylinder 50, the second inner cylinder 40, and the first inner cylinder 130 clockwise relative to the cap 120. They continue rotating until the protruding portion 121C returns to its original position and a click is felt when it passes over the slit 132S. Thus, the user can recognize that the outer cylinder 50, the second inner cylinder 40, and the first inner cylinder 130 are fully closed.

[0085] As described above, the modified measuring and dispensing container 2 includes a cap 120 that is screwed onto the mouth 11 of the bottle 10 so as to come off when rotated in one rotational direction when viewed from the Z direction, a first inner cylinder 130 connected to the cap 120, a second inner cylinder 40 provided on the outer circumference of the first inner cylinder 130 and connected to the first inner cylinder 130, and an outer cylinder 50 provided on the outer circumference of the second inner cylinder 40 and connected to the second inner cylinder 40. The first inner cylinder 130 has a concave cam portion 134 provided on its outer surface, and the cam portion 134 has a first path 134A formed along the inclination direction, a second path 134B formed along the Z direction continuous with the first path 134A, and a third path 134C formed along the horizontal direction continuous with the first path 134A and the second path 134B. The second inner cylinder 40 has a projection 46 on its inner circumference, and by rotating the second inner cylinder 40 in a rotational direction other than the Z direction, the projection 46 of the second inner cylinder 40 moves along the first path 134A of the cam portion 134, and metering is performed. With the metering and dispensing container 2 configured in this way, the rotational direction when removing the cap 120 from the bottle 10 and the rotational direction when rotating the second inner cylinder 40 for metering are opposite to each other, so the cap 120 can not be rotated together with the container.

[0086] It should be noted that the present invention is not limited to the embodiments described above, and can be modified in various ways within the scope of the claims.

[0087] For example, in the embodiment described above, the cam portion 34 had a fourth path 34D, but it does not have to have a fourth path.

[0088] Furthermore, in the above-described modification, one direction of rotation was counterclockwise and the other direction of rotation was clockwise, but it is also possible for one direction of rotation to be clockwise and the other direction of rotation to be counterclockwise.
