It further comprises a top cover that closes the upper end of the peripheral wall, and a hinge that integrally connects the top cover to the measuring device, wherein the pipe portion comprises an upper pipe portion integrally provided with the top cover and connected to the suction port at its upper end, and a lower pipe portion integrally provided with the measuring device and connected to the lower end of the upper pipe portion at its upper end, with its lower end opening at the bottom wall portion. It is characterized by the following:

[0009] In the dispenser of the present invention, it is preferable that the lower pipe portion is positioned inside the measuring device, spaced apart from the peripheral wall, and integrally connected to the bottom wall at its lower end.

[0010] The dispensing container of the present invention is characterized by comprising a container body having a mouth and for storing liquid, and one of the above-mentioned dispensers. [Effects of the Invention]

[0011] According to the present invention, it is possible to provide a dispenser and a dispensing container that can easily dispense only a specified amount of liquid. [Brief explanation of the drawing]

[Figure 2] This is a cross-sectional view of the measuring instrument shown in Figure 1. [Figure 3] This is a cross-sectional view along line AA in Figure 2. [Figure 4] Figure 1 is a cross-sectional view of the dispensing container in an inverted position, with liquid being filled into the measuring device. [Figure 5] Figure 1 is a cross-sectional view of the dispensing container after the liquid has been measured by a measuring device. [Figure 6] Figure 1 is a cross-sectional view of the dispensing container after all the liquid measured by the measuring device has been dispensed. [Modes for carrying out the invention]

[0013] Hereinafter, a dispenser and dispensing container according to one embodiment of the present invention will be described in detail with reference to the drawings.

[0014] As shown in Figure 1, the dispenser 1 according to one embodiment of the present invention is used by being attached to the mouth 2a of a container body 2 that stores liquid L. The dispenser 1 and the container body 2 constitute the dispensing container 3 according to this embodiment.

[0015] In this specification and in the claims, the vertical direction refers to the vertical direction when the dispenser 1 or dispensing container 3 is in the upright position shown in Figure 1. The radial direction refers to the direction along a straight line passing through the axis O of the container body 2 and perpendicular to said axis O.

[0016] The container body 2 is, for example, a bottle made of synthetic resin. The mouth 2a of the container body 2 is cylindrical (in the illustrated case, cylindrical), and its interior can store a liquid L, for example, an activating solution for plant cultivation.

[0017] The dispenser 1 includes a liquid L suction port 10, an operating unit 11, a liquid L discharge port 12, and an operating unit 13 that, when the operating unit 11 is operated, pumps the liquid L drawn in from the suction port 10 to the discharge port 12. When the operating unit 11 is operated, the dispenser 1 uses the operating unit 13 to pump the liquid L stored in the container body 2 from the suction port 10 to the discharge port 12, dispensing a predetermined amount of liquid L to the outside from the discharge port 12.

[0018] In this embodiment, the dispenser 1 is a trigger-type pump dispenser. In this case, the dispenser 1 has a main body 15 fixed to the opening 2a using a mounting cap 14. The main body 15 has a mounting bracket 15a with a flange that is sandwiched and held between the mounting cap 14 and the opening 2a, and the suction port 10 is integrally provided on the mounting bracket 15a in a cylindrical shape that opens downward toward the inside of the opening 2a. Inside the main body 15, there is an L-shaped flow path 16 connected to the suction port 10, and the discharge port 12 is provided connected to the downstream end of the flow path 16. More specifically, the discharge port 12 is provided as an opening in a nozzle 17 attached to the main body 15. The operating unit 13 is a piston-type pump having a piston 13a and a cylinder 13b provided in the middle of the flow path 16. Check valves 18 and 19 are provided on the downstream and upstream sides of the portion of the operating unit 13 that communicates with the flow path 16, respectively. The operating unit 11 is a lever that is pivotably supported on the main body 15. By pulling the operating unit 11, the pump, which is the operating unit 13, is activated. When the pump, which is the operating unit 13, is activated, the check valve 18 opens and the check valve 19 closes, and the liquid L inside the pump is pressurized and sent through the flow path 16 to the discharge port 12, and discharged to the outside from the discharge port 12. When the pulling operation of the operating unit 11 is released and the operating unit 11 returns to its original position, the check valve 18 closes and the check valve 19 opens, and the liquid L stored in the container body 2 is filled into the inside of the pump, which is the operating unit 13, through the flow path 16 from the suction port 10. Therefore, by repeatedly operating the operating unit 11, the liquid L stored in the container body 2 can be discharged in predetermined amounts.

[0019] Furthermore, the dispenser 1 is not limited to the trigger-type pump dispenser described above. Any dispenser 1 can be used that includes a liquid suction port 10, an operating unit 11, a liquid discharge port 12, and an operating unit 13 that, when the operating unit 11 is operated, pumps the liquid L drawn from the suction port 10 to the discharge port 12. For example, a pump dispenser with a push-down head or a spray dispenser can be used.

[0020] In order to enable the dispenser 1 of the present embodiment to easily discharge only a specified amount A of the liquid L stored in the container body 2, it has a measuring device 20. The measuring device 20 is supported by the dispenser 1 and disposed inside the container body 2. The specified amount A can be arbitrarily set as long as it is less than the maximum amount of the liquid L that can be stored in the container body 2.

[0021] As shown in FIGS. 1, 2, and 3, the measuring device 20 has a bottomed cylindrical shape having a peripheral wall 21 and a bottom wall 22 that closes the lower end of the peripheral wall 21. In the present embodiment, the measuring device 20 has a test tube shape in which the peripheral wall 21 is cylindrical and the bottom wall 22 is hemispherical. Note that the shape of the measuring device 20 is not limited to the test tube shape.

[0022] The peripheral wall 21 is provided with an inlet 23 for the liquid L. In the present embodiment, a plurality of inlets 23 formed in a vertically long window shape extending along the vertical direction are provided at eight positions at equal intervals in the circumferential direction on the upper part of the peripheral wall 21. The plurality of inlets 23 are sized such that when the discharge container 3 is in an inverted posture, the liquid L stored in the container body 2 can be introduced into the measuring device 20.

[0023] The lower end positions of these plurality of inlets 23 are the same, and the volume of the portion below the lower end positions of the plurality of inlets 23 of the measuring device 20 is the specified amount A.

[0024] Note that at least one inlet 23 may be provided on the peripheral wall 21, and the shape of the inlet 23 can be variously changed. Also, as long as the volume of the portion below the lower end position of the inlet 23 of the measuring device 20 is the specified amount A, the lower end position of the inlet 23 can be set at any height of the peripheral wall 21.

[0025] The dispenser 1 of this embodiment has a pipe section 30. The pipe section 30 is cylindrical, and its upper end is connected to the suction port 10 of the dispenser 1, while its lower end has an opening 33 in the bottom wall 22 inside the measuring device 20.

[0026] In this embodiment, the dispenser 1 is equipped with a top lid 40 that closes the upper end of the peripheral wall 21. The measuring device 20 and the top lid 40 form a measuring member 50.

[0027] The top cover 40 has a cap shape, comprising a cylindrical peripheral wall 41 that is the same diameter and coaxial as the peripheral wall 21, and a flat top wall 42 that closes the upper end of the peripheral wall 41. The top cover 40 is positioned at the upper end of the peripheral wall 21 and closes its upper end. The top cover 40 is integrally connected to the weighing device 20 by a hinge 43.

[0028] The top cover 40 is integrally provided with a cylindrical upper pipe section 31, which forms part of the upper side of the pipe section 30. The upper pipe section 31 protrudes from the top wall 42 on both the upper and lower sides at a position offset from the axis of the top wall 42, and its upper end is connected by being fitted and fixed inside the suction port 10 of the dispenser 1.

[0029] On the other hand, the measuring instrument 20 is integrally provided with a cylindrical lower pipe section 32 that forms part of the lower side of the pipe section 30. The lower pipe section 32 is offset from the axis of the peripheral wall 21 and coaxial with the upper pipe section 31, and is arranged inside the peripheral wall 21, spaced apart from the peripheral wall 21, to form a double structure, and is connected to the outside of the lower end of the upper pipe section 31 at its upper end by fitting. Furthermore, the lower pipe section 32 is integrally connected to the bottom wall 22 at its lower end, and an opening 33 is provided on a part of the outer circumference at the lower end. The lower pipe section 32 communicates with the inside of the measuring instrument 20 through the opening 33 that opens in the bottom wall 22.

[0030] The measuring member 50 with the above configuration is supported by the dispenser 1 by fitting and fixing the upper end of the pipe section 30 or upper pipe section 31 to the suction port 10, and fitting and fixing the top lid 40 to the mounting bracket 15a. A vertical rib 41a extending in the vertical direction is integrally provided on the peripheral wall 41 of the top lid 40, and an air exchange channel extending in the vertical direction along the vertical rib 41a is provided between the mounting bracket 15a and the top lid 40. This channel communicates with the inside of the container body 2 and with the outside through an outside air introduction hole 15b provided in the mounting bracket 15a, so that when liquid L is dispensed, outside air is introduced into the inside of the container body 2 from the outside. This prevents the inside of the container body 2 from being depressurized when liquid L is dispensed. The measuring member 50 may be supported by the dispenser 1 with other configurations.

[0031] As described above, the weighing component 50 has a configuration in which the weighing device 20 and the top lid 40 are integrally connected by a hinge 43. Therefore, by injection molding of a synthetic resin material to form a component with the shape shown by the dashed line in Figure 2, and then rotating the top lid 40 90 degrees around the hinge 43 toward the upper end of the weighing device 20, the weighing component 50 of the above shape can be easily and inexpensively manufactured as a single part.

[0032] Next, we will describe the procedure for dispensing a specified amount A of liquid L from a dispensing container 3 equipped with the dispenser 1 described above.

[0033] First, from the state shown in Figure 1, the dispensing container 3 is inverted so that the dispenser 1 is on the lower side relative to the container body 2. As shown in Figure 4, when the dispensing container 3 is inverted, the liquid L stored in the container body 2 is filled into the inside of the measuring device 20 through the multiple intake ports 23.

[0034] In this embodiment, since the multiple intake ports 23 are vertically elongated, the liquid L can be effectively filled into the inside of the measuring device 20.

[0035] Next, the dispensing container 3 is returned from the inverted position to the upright position. As shown in Figure 5, when the dispensing container 3 is returned from the inverted position to the upright position, the inside of the measuring device 20 is filled with an amount of liquid L such that the liquid level of the liquid L is located at the lower end of the multiple intake ports 23, i.e., a specified amount A of liquid L. At this time, the liquid level of the liquid L stored in the container body 2 is located below the lower end of the multiple intake ports 23.

[0036] Therefore, as shown in Figure 5, when the operating unit 11 is operated to activate the operating unit 13 with the metering device 20 filled with a specified amount A of liquid L, only the liquid L inside the metering device 20 is sucked through the opening 33 and the pipe section 30 to the suction port 10, and then discharged to the outside through the flow path 16 and the discharge port 12.

[0037] When the operation unit 11 is operated repeatedly and all of the liquid L inside the measuring device 20 is discharged to the outside through the discharge port 12, as shown in Figure 6, even if there is liquid L remaining inside the container body 2, this liquid L will not be drawn into the suction port 10, and liquid L will no longer be discharged from the discharge port 12. Therefore, the user can recognize that the specified amount A of liquid L has been discharged to the object to be coated by the fact that liquid L will no longer be discharged from the discharge port 12, and an excessive amount of liquid L will not be applied to the object to be coated.

[0038] Thus, in the dispenser 1 to the dispensing container 3 of this embodiment, the dispenser 1 is equipped with the measuring device 20 and pipe section 30 as described above, making it easy to dispense only the specified amount A of liquid L.

[0039] Furthermore, in the dispenser 1 to the dispensing container 3 of this embodiment, the upper lid 40 is integrally provided on the measuring device 20 via a hinge 43, and the pipe section 30 is configured to have the upper pipe section 31 and the lower pipe section 32 as described above. This allows the measuring member 50 to be formed as a single part by injection molding of a synthetic resin material, thereby reducing the cost of the dispenser 1 to the dispensing container 3.

[0040] Furthermore, in the dispenser 1 or dispensing container 3 of this embodiment, the lower pipe section 32 is positioned inside the measuring device 20, spaced apart from the peripheral wall 21, and is integrally connected to the bottom wall 22 at its lower end. This configuration allows the pipe section 30 to effectively draw the liquid L inside the measuring device 20 through the opening 33 with a simple structure, thereby reducing the cost of the dispenser 1 or dispensing container 3.

[0041] The present invention is not limited to the embodiments described above, and can be modified in various ways without departing from its spirit.

[0042] For example, in the above embodiment, the top lid 40 and hinge 43 are provided integrally on the weighing device 20, but a configuration without the top lid 40 and hinge 43 is also possible. [Explanation of symbols]
