[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0015] As shown in FIGS. 1 to 3, a measuring cap 1 according to one embodiment of the present invention forms a measuring and dispensing container 3 by being attached to a mouth portion 2a of a container body 2.

[0016] The container body 2 is bottle-shaped and has a cylindrical mouth 2a centered on the central axis O, a body 2b connected to the lower end of the mouth 2a, and a bottom (not shown) connected to the lower end of the body 2b. Note that the mouth 2a may be in a tubular shape other than a cylindrical shape, such as a rectangular tubular shape.

[0017] In this embodiment, the direction along the central axis O of the mouth 2a is also referred to as the axial direction or the vertical direction, the direction from the bottom toward the mouth 2a along the vertical direction is also referred to as the upward direction, and the opposite direction is also referred to as the downward direction, the direction along a straight line perpendicular to the central axis O is also referred to as the radial direction, the direction circumferentially around the central axis O is also referred to as the circumferential direction, and a cross section including the central axis O is also referred to as a longitudinal cross section.

[0018] Contents (not shown) are accommodated inside the container body 2 (contents accommodation space). The contents are not particularly limited, but are in powder form in this embodiment. The contents may be in a form other than powder, for example, liquid. Examples of the contents include detergent, food, etc.

[0019] The metering cap 1 has an outer peripheral wall 4, an inner peripheral wall 5, a bottom wall 6, a first partition wall 7, a top wall 8, an inlet opening / closing portion 9, a second partition wall 10, and an operation portion 11. The metering cap 1 also has a movable portion 12 connected to the top wall outer peripheral portion 8a. The movable portion 12 has a movable portion main body 13, an elastic membrane portion 14, the inlet opening / closing portion 9, the second partition wall 10, and the operation portion 11. The movable portion main body 13 has a cylindrical wall 13a and a top wall 13b. The cylindrical wall 13a has a discharge port 15, and the elastic membrane portion 14 has a discharge port opening / closing portion 16. The top wall 8 has the top wall outer peripheral portion 8a, the elastic membrane portion 14, and the movable portion main body 13.

[0020] The measuring cap 1 is composed of two parts, an inner cap 1a and an outer cap 1b, and each part is made of, for example, synthetic resin and formed by, for example, injection molding. The inner cap 1a has a lower part of the outer circumferential part 8a of the top wall, an inner circumferential wall 5, a bottom wall 6, and a first partition wall 7, and the outer cap 1b has an outer circumferential wall 4, an upper part of the outer circumferential part 8a of the top wall, and a movable part 12. The measuring cap 1 may be configured to be divided into two parts at a portion different from that of this embodiment. Furthermore, the number of parts for forming the measuring cap 1 is not limited to two.

[0021] The outer peripheral wall 4 is cylindrical and centered on the central axis O, and the inner peripheral surface of the outer peripheral wall 4 is attached to the outer peripheral surface of the mouth portion 2a by engagement between the concave and convex shapes, more specifically, engagement between a female threaded portion provided on the outer peripheral wall 4 and a male threaded portion provided on the mouth portion 2a. Note that the engagement between the concave and convex shapes is not limited to threaded engagement. The top wall outer peripheral portion 8a is annular and centered on the central axis O when viewed from above, and the lower surface of the top wall outer peripheral portion 8a abuts against the upper end surface of the mouth portion 2a when the outer peripheral wall 4 is attached to the mouth portion 2a.

[0022] The inner peripheral wall 5 has a cylindrical shape centered on the central axis O, and is disposed radially inside the mouth portion 2a. More specifically, the outer peripheral surface of the inner peripheral wall 5 abuts against the inner peripheral surface of the mouth portion 2a. The outer peripheral surface of the inner peripheral wall 5 and the inner peripheral surface of the mouth portion 2a may not abut against each other. A bottom wall 6 is continuous with the lower end portion of the inner peripheral wall 5.

[0023] The movable part 12 is movable between an open position shown in Fig. 1 and a closed position shown in Fig. 4. Between the movable part 12 and the bottom wall 6, in an open state in which the movable part 12 is in the open position, a first flow path 17 from inside the container body 2 to inside the measuring chamber 19, an inlet 18 of the measuring chamber 19, the measuring chamber 19, the storage chamber 20, a second flow path 21 from inside the storage chamber 20 to the discharge port 15, and the discharge port 15 are provided in this order to form a flow path for the contents.

[0024] As shown in Fig. 1, in the open state, the inlet opening / closing part 9 opens the inlet 18 of the measuring chamber 19, and the discharge outlet opening / closing part 16 opens the discharge outlet 15. As shown in Fig. 4, in the closed state where the movable part 12 is in the closed position, the inlet opening / closing part 9 closes the inlet 18 of the measuring chamber 19, and the discharge outlet opening / closing part 16 closes the discharge outlet 15. The inlet opening / closing part 9 abuts against the first partition wall 7 in the closed state, and does not abut against the first partition wall 7 in the open state. The discharge outlet opening / closing part 16 overlaps with the discharge outlet 15 in the closed state, and does not overlap with the discharge outlet 15 in the open state.

[0025] As shown in Figs. 1 to 3, the movable part body 13 is connected to the inner peripheral edge of the top wall outer peripheral part 8a by the elastic membrane part 14. More specifically, the movable part body 13 is connected to a part (first part) of the inner peripheral edge of the top wall outer peripheral part 8a via a hinge part 22 so as to be rotatable in the axial direction (up and down direction) of the mouth part 2a, and the elastic membrane part 14 connects the remaining part (second part) of the inner peripheral edge of the top wall outer peripheral part 8a to the movable part body 13. The movable part body 13 is in the shape of a cylinder with a top wall 13b and a cylindrical wall 13a, and the hinge part 22 is connected to the lower end of the cylindrical wall 13a. A discharge port 15 is provided at a position on the cylindrical wall 13a opposite to the hinge part 22 in a top view.

[0026] The rotation axis P of the hinge portion 22 extends in a horizontal direction perpendicular to the up-down direction. Hereinafter, the direction along the rotation axis P is also referred to as the left-right direction, the direction perpendicular to both the up-down direction and the left-right direction is also referred to as the front-rear direction, the direction from the hinge portion 22 toward the discharge port 15 along the front-rear direction is also referred to as the front, and the opposite direction is also referred to as the rear.

[0027] In the open state, the tube wall 13a is tubular with a diameter smaller than that of the inner peripheral edge of the top wall outer peripheral portion 8a, centered on an axis parallel to the rear of the central axis O, and with a front end and a rear end that are flat. The lower end edge of the tube wall 13a is inclined upward toward the front in the open state. The top wall 13b is inclined upward toward the front at a steeper angle than the lower end edge of the tube wall 13a in the open state. A portion (first portion) located at the lower end of the flat rear end at the lower end of the tube wall 13a is connected to the hinge portion 22. A portion (second portion) at the lower end of the tube wall 13a where the hinge portion 22 is not provided is connected to the upper end of the elastic membrane portion 14. In the open state, the elastic membrane portion 14 extends upward from the second portion of the inner peripheral edge of the top wall outer peripheral portion 8a toward the second portion of the lower end of the tube wall 13a. The portion of the elastic membrane portion 14 located in front of the discharge port 15 constitutes a discharge port opening / closing portion 16 .

[0028] The flat front end of the cylindrical wall 13a has a plurality of through holes 15a that form the discharge port 15. The number of through holes 15a can be set appropriately. The operating part 11 has a plate shape that protrudes upward from the front end of the top wall 13b in the open state, and more specifically, has a bent plate shape that bends forward and upward in the open state.

[0029] In the open state, the second partition wall 10 is flat and perpendicular to the front-rear direction, and extends downward from the top wall 13b beyond the lower end of the cylindrical wall 13a and the lower end of the elastic membrane portion 14. Both left and right ends of the second partition wall 10 are continuous with the cylindrical wall 13a at portions above the lower end of the cylindrical wall 13a. The portions between the lower end of the cylindrical wall 13a and the lower end of the elastic membrane portion 14 at both left and right ends of the second partition wall 10 are close to the inner peripheral surface of the elastic membrane portion 14 in the open state. The portions below the lower end of the elastic membrane portion 14 at both left and right ends of the second partition wall 10 are close to the inner peripheral surface of the top wall outer peripheral portion 8a in the open state.

[0030] In the open state, the inlet opening / closing part 9 is a flat plate that is vertical to the front-rear direction and extends downward from the top wall 13b to near the lower end of the cylindrical wall 13a. Both left and right ends of the inlet opening / closing part 9 are connected to the cylindrical wall 13a at portions above the lower end of the cylindrical wall 13a.

[0031] The bottom wall 6 has a generally D-shape with a missing rear end when viewed from above. The first partition wall 7 has a flat plate shape perpendicular to the front-rear direction in the open state, and extends upward from the rear end of the bottom wall 6 to the height of the inner peripheral edge of the top wall outer peripheral portion 8a. Both left and right ends of the first partition wall 7 are continuous with the inner peripheral wall 5 and the inner peripheral edge of the top wall outer peripheral portion 8a. The upper end of the first partition wall 7 is located above the lower end of the second partition wall 10.

[0032] The first partition wall 7 separates the first flow path 17 from the storage chamber 20. In the open state, the inlet 18 of the metering chamber 19 is formed between the upper end of the first partition wall 7 and the lower end of the inlet opening / closing portion 9. In the open state, the metering chamber 19 is formed between the inlet opening / closing portion 9 and the second partition wall 10 in the front-rear direction, and between the upper end of the first partition wall 7 and the top wall 13b in the up-down direction. In the open state, the storage chamber 20 is formed in a portion of the inner circumferential wall 5 adjacent to the bottom wall 6 and in a portion surrounded by the bottom wall 6 and the first partition wall 7. In the open state, the second partition wall 10 separates the metering chamber 19 from the second flow path 21.

[0033] 4, in the closed state, the elastic membrane portion 14 extends downward from the second portion of the inner peripheral edge portion of the top wall outer peripheral portion 8a toward the second portion of the lower end portion of the cylindrical wall 13a. Also, in the closed state, the top wall 13b is disposed horizontally, and the operating portion 11 protrudes radially outward (forward) beyond the outer peripheral wall 4.

[0034] A user can operate the operating unit 11 to move the movable part 12 downward relative to the storage chamber 20 by elastic deformation of the elastic membrane part 14, thereby changing the metering and dispensing container 3 from a closed state to an open state and from an upright position to an inverted position, thereby bringing about a first state in which a part of the contents has moved from inside the container body 2 into the measuring chamber 19 through the entrance 18 of the measuring chamber 19. At this time, the contents are introduced into the measuring chamber 19 until the vertical upper surface of the contents in the measuring chamber 19 reaches the upper end of the first partition wall 7. When the vertical upper surface of the contents in the measuring chamber 19 reaches the upper end of the first partition wall 7, it becomes difficult for air to flow into the container body 2 to be replaced by the contents, and the flow of the contents into the measuring chamber 19 stops.

[0035] Then, the user can change the metering and dispensing container 3 from the first state to an upright position, thereby changing the state to a second state in which an amount of contents corresponding to the volume of the metering chamber 19 has moved from inside the metering chamber 19 to inside the storage chamber 20, and can discharge the contents in the storage chamber 20 from the discharge port 15 by changing the metering and dispensing container 3 from the second state to an inverted position.

[0036] Furthermore, by turning the metered dispensing container 3 from the second state to an inverted position as described above, the user can turn the metered dispensing container 3 into the first state in parallel with discharging the content in the storage chamber 20. Therefore, the user can, for example, operate the operating unit 11 in the second state to turn the metered dispensing container 3 into a closed state and store the metered dispensing container 3 until the next use.

[0037] At this time, the entrance 18 of the metering chamber 19 is closed by the entrance opening / closing part 9. Therefore, even if the metering discharge container 3 is tilted when it is carried, the inflow and outflow of the contents between the container body 2 and the storage chamber 20 via the metering chamber 19 can be suppressed. As a result, the variation in the amount of the contents discharged when the metering discharge container 3 is opened again and is initially set to the first state can be suppressed. In this way, according to this embodiment, the variation in the amount of the contents discharged when the discharge port 15 is opened and initially discharged can be suppressed.

[0038] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and scope of the present invention.
