Description

Technical Field

[0001] The present invention relates to a metering dispensing container that houses a content such as a chemical solution and can dispense the content in a fixed amount at a time.

Background Art

[0002] As such a metering dispensing container, for example, a metering dispensing container that houses a chemical solution such as a medicinal hair growth agent is known (Patent Document 1). As shown in FIG. 9, the metering dispensing container includes a container body 912 having an outlet 914 formed at an upper end portion, a middle plug 918 attached to the outlet 914, a graduated cylinder member 936 attached to the middle plug 918, a valve member 940 provided inside the graduated cylinder member 936, and a cap 956.

[0003] The middle plug 918 has a cylindrical attachment portion 920 fitted inside the outlet 914 and a partition wall portion 924 that closes the opening of the attachment portion 920. A circular through-hole 926 is formed at the center of the partition wall portion 924. A stepped portion 934 cut out in an L-shaped cross-section is formed in a circle around the through-hole 926 at the peripheral edge of the through-hole 926.

[0004] The graduated cylinder member 936 has a cylindrical side surface 936a and an upper surface portion 936b that closes the tip of the side surface 936a. An insertion port 938 is formed at the center of the upper surface portion 936b. A stepped portion 939 cut out in an L-shaped cross-section inside the upper surface portion 936b is formed in a circle around the inner peripheral side surface of the insertion port 938.

[0005] The valve member 940 has a cylindrical portion 942, a first valve 944 that protrudes laterally from the peripheral surface of the lower end portion of the cylindrical portion 942, and a second valve 946 that protrudes laterally from the peripheral surface of the upper end portion of the cylindrical portion 942. As shown in FIG. 11, the first valve 944 closes the through-hole 926 of the middle plug 918 and adheres to the inner peripheral side surface 934a of the stepped portion 934. As shown in FIG. 10, the second valve 946 closes the insertion port 938 of the graduated cylinder member 936 and adheres to the inner peripheral side surface 939a of the stepped portion 939.

[0006] In this quantitative dispensing container, the valve member 940 is slidable between a dispensing state in which the first valve 944 closes the through-hole 926 of the stopper 918, and a metering state in which the second valve 946 closes the insertion opening 938 of the measuring cylinder member 936. That is, by sliding the valve member 940, the through-hole 926 of the stopper 918 and the insertion opening 938 of the measuring cylinder member 936 can be alternately opened and closed. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Patent No. 3759428 [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] However, in the conventional quantitative dispensing container described above, when the stopper 918 of the first valve 944 contacts and releases contact with the stepped portion 934, and when the measuring cylinder member 936 of the second valve 946 contacts and releases contact with the stepped portion 939, the valve member 940 slides in close contact with the inner circumferential surface 934a of the stepped portion 934 and the inner circumferential surface 939a of the stepped portion 939, resulting in high resistance.

[0009] Therefore, the present invention aims to provide a quantitative dispensing container that reduces resistance when moving a dispensing part such as a valve member. [Means for solving the problem]

[0010] The quantitative dispensing container of the present invention comprises a container body portion configured to accommodate a contents inside and having an opening for putting in and taking out the contents; an inner stopper portion attached to the opening and having an inner stopper communication portion formed therein that communicates with the inside of the container body portion; a storage body portion together with the inner stopper portion to form a storage chamber communicating with the inside of the container body portion through the hole in the inner stopper communication portion; a storage forming portion provided in the storage body portion and having a storage communication portion formed therein that communicates with the storage chamber; and a dispensing portion configured to dispense the contents in the storage chamber and having a dispensing path formed therein that communicates with the storage chamber through the hole in the storage communication portion, comprising an inner stopper opening / closing portion for opening and closing the hole in the inner stopper communication portion, and a portion for opening and closing the hole in the storage communication portion. A dispensing unit comprising a storage opening / closing unit and a dispensing unit, which is inserted into the storage chamber through a hole in the storage communication unit and is configured to move between a storage position where the inner stopper opening / closing unit opens the hole in the inner stopper communication unit and the storage opening / closing unit closes the hole in the storage communication unit and a dispensing position where the inner stopper opening / closing unit closes the hole in the inner stopper communication unit and the storage opening / closing unit opens the hole in the storage communication unit, wherein at least one of the opening / closing units of the inner stopper opening / closing unit and the storage opening / closing unit is provided with a sliding unit that slides in the direction of movement between the inner stopper communication unit and the storage communication unit as the dispensing unit moves between the storage position and the dispensing position, and the sliding unit is provided with a notch that reduces the thickness of the sliding unit in the direction of movement.

[0011] With this configuration, since the sliding part has a notch, the thickness of the part of the sliding part that slides against the stopper communication part or the storage communication part becomes thinner in the direction of movement. Therefore, the part of the sliding part that slides against the stopper communication part or the storage communication part becomes more easily deformed when sliding, and the resistance to sliding can be suppressed. Consequently, the resistance when moving the dispensing part can be suppressed.

[0012] In the quantitative dispensing container of the present invention, the dispensing portion comprises a dispensing cylinder portion in which the dispensing passage is formed, the sliding portion protrudes outward from the outer peripheral surface of the dispensing cylinder portion in a direction intersecting the direction of movement, and the tip portion in the protruding direction is configured to slide with respect to at least one of the communicating portions, and the notch portion may be provided at the tip portion of the sliding portion.

[0013] With this configuration, a notch is provided at the protruding tip of the sliding part, so that the tip of the thinned sliding part, which is the part that slides against the inner plug communication part or the storage communication part, is easily deformed, and the resistance to sliding can be suppressed. Therefore, the resistance when moving the dispensing part can be suppressed.

[0014] In the quantitative dispensing container of the present invention, the notch is provided in the middle of the thickness in the direction of movement at the tip of the sliding part, and the tip of the sliding part may have a sliding tip that slides against at least one of the communicating parts on one side and the other side in the direction of movement via the notch.

[0015] With this configuration, a notch is provided in the middle of the thickness in the direction of movement at the tip of the sliding part. Therefore, in both the case of movement to one side and the case of movement to the other side, the thinned sliding tip is easily deformed, and sliding resistance can be suppressed. Accordingly, resistance can be suppressed when moving the dispensing part to one side, and resistance can be suppressed when moving the dispensing part to the other side.

[0016] The quantitative dispensing container of the present invention comprises: a dispensing section comprising: a bottomed cylindrical dispensing section formed such that its interior forms the dispensing passage and its tip is open; a tip dispensing section fitted into the opening at the tip of the dispensing section, having a dispensing hole formed at the tip; a dispensing introduction section communicating with the dispensing hole and forming the dispensing passage from the base end of the dispensing introduction section, having an introduction hole with a larger diameter than the dispensing hole; and a dispensing step section formed between the dispensing section and the dispensing introduction section. The plug body comprises a plug portion having an outlet, a plug tip portion that is inserted into the dispensing hole and whose tip is movable in and out of the outlet, and a plug opening / closing portion provided on the base end side of the plug tip portion and formed to be larger in diameter than the plug tip portion, which opens and closes the dispensing hole from the base end side by moving toward and toward the dispensing step portion, wherein the plug body portion may be configured such that, when the plug tip portion is retracted so as not to protrude out of the dispensing hole, the plug opening / closing portion is spaced apart from the dispensing step portion toward the base end and is positioned toward the base end side of the dispensing introduction portion.

[0017] With this configuration, when the tip of the stopper is retracted into the dispensing hole, the stopper opening / closing mechanism is positioned closer to the base end than the dispensing introduction section, so that the large-diameter stopper opening / closing mechanism extends from the dispensing introduction section towards the base end. Therefore, when the tip of the stopper is retracted into the dispensing hole, the contents entering the dispensing path smoothly enter the introduction hole of the dispensing introduction section, making it easier to dispense the contents from the dispensing hole.

[0018] In the quantitative dispensing container of the present invention, the dispensing spout portion comprises a spout fitting portion that is fitted into the opening on the tip side of the dispensing cylinder portion, and a spout tip portion provided on the tip side of the spout fitting portion and protruding from the tip of the dispensing cylinder portion toward the tip side, having an outer diameter larger than that of the spout fitting portion, and having the dispensing hole formed in the radial center portion, wherein the ratio of the outer diameter (D1) of the spout tip portion to the inner diameter (D2) of the dispensing hole is D1:D2 = 1.0:1.2 to 1.0:1.8, and the ratio of the radial dimension (D4) from the outer diameter of the spout tip portion to the edge of the dispensing hole to the radial dimension (D3) from the radial outer edge of the spout tip portion to the edge of the dispensing hole may be D4:D3 = 1.0:2.5 to 1.0:4.5.

[0019] With this configuration, D1:D2 = 1.0:1.2 to 1.0:1.8 and D4:D3 = 1.0:2.5 to 1.0:4.5, so when applying the contents dispensed from the dispensing hole by spreading it at the tip of the nozzle, it is possible to dispense an appropriate amount of contents while spreading and applying the dispensed contents without scattering. [Effects of the Invention]

[0020] Based on the above, the present invention provides a quantitative dispensing container that reduces resistance when moving dispensing parts such as valve members. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0022] Hereinafter, a metering dispensing container according to an embodiment of the present invention will be described with reference to FIGS. 1 to 8.

[0023] The quantitative dispensing container 1 according to this embodiment comprises a container body 2, as shown in Figure 1. Furthermore, as shown in Figure 2, the quantitative dispensing container 1 comprises an inner stopper 3, a storage and forming section 4, and a dispensing section 5. In addition, the quantitative dispensing container 1 comprises an inner cap 11 and an outer cap 12. This quantitative dispensing container 1 is a container that can hold medicinal liquids such as medicinal hair growth agents and cosmetic liquids, and can measure and dispense a single-use amount. The quantitative dispensing container 1 of this embodiment can, for example, measure and dispense 1 ml of medicinal liquid for a single use.

[0024] The container body 2 is configured to accommodate contents inside. The container body 2 also has an opening 20 for inserting and removing contents. The container body 2 also comprises a cylindrical body 21, a shoulder 22 connecting the body 21 and the opening 20, and a bottom 23 closing the opening on the axial base end side of the body 21. Each part 20, 21, 22, and 23 of the container body 2 is formed integrally. However, the container body 2 may also be formed by combining at least one of these parts 20, 21, 22, and 23, which are formed separately. The material of the container body 2 is synthetic resin, but it may also be glass or the like.

[0025] In the quantitative dispensing container 1, the side where the mouth portion 20 of the container body portion 2 is located, i.e., the upper side in Figure 2, is the "tip side," and the side where the bottom portion 23 of the container body portion 2 is located, i.e., the lower side in Figure 2, is the "base end side." Furthermore, the "axial direction" of the quantitative dispensing container 1 is the cylindrical axis direction of the container body portion 2. In addition, the radial direction perpendicular to the axial direction is simply referred to as the "radial direction."

[0026] The body portion 21 is, for example, cylindrical. The outer diameter of the body portion 21 is the same at all points along the axial direction, but may differ at least in some parts along the axial direction. For example, the body portion 21 may have a tapered shape or a shape that bulges circumferentially in the central part along the axial direction. The body portion 21 may also be rectangular.

[0027] The mouth portion 20 is, for example, substantially cylindrical. The mouth portion 20 is connected to the inner end of the shoulder portion 22. The outer diameter of the mouth portion 20 is smaller than the outer diameter of the body portion 21. In this embodiment, as shown in Figure 3A, the mouth portion 20 has a first mouth portion fitting portion 201 into which the storage forming portion 4 fits, and a second mouth portion fitting portion 202 into which the inner cap 11 fits.

[0028] The first mouth fitting portion 201 constitutes the tip of the mouth portion 20. A rib 2010 projecting radially outward is provided continuously around the tip of the outer circumferential surface of the first mouth fitting portion 201.

[0029] The second mouth fitting portion 202 is connected to the base end side of the first mouth fitting portion 201. The second mouth fitting portion 202 also comprises a cylindrical mouth body portion 2020 and a male screw 2021 provided on the outer circumference of the mouth body portion 2020. The outer diameter of the second mouth fitting portion 202 is larger than the outer diameter of the first mouth fitting portion 201. The inner circumferential surface of the second mouth fitting portion 202 is flush with the inner circumferential surface of the first mouth fitting portion 201.

[0030] The shoulder portion 22 is, for example, annular, specifically circular (see Figure 2). The shoulder portion 22 is connected to the torso portion 21 so as to extend radially inward from the tip of the torso portion 21 toward the base of the mouth portion 20. In this embodiment, the shoulder portion 22 comprises a circular shoulder body portion 220 and shoulder projections 221 that protrude toward the tip from the shoulder body portion 220. There are multiple shoulder projections 221, specifically four. The four shoulder projections 221 are provided at equal intervals in the circumferential direction.

[0031] The bottom portion 23 is, for example, flat, and more specifically, disc-shaped. The bottom portion 23 is connected to the base end of the body portion 21 so as to extend radially inward.

[0032] The inner stopper portion 3 is a component attached to the opening portion 20. The inner stopper portion 3 also includes an inner stopper communication portion 30 having a hole 300 that communicates with the inside of the container body portion 2 (see Figure 3A). Furthermore, the inner stopper portion 3 includes an inner stopper side wall portion 31 provided at the radially outer end of the inner stopper communication portion 30. The inner stopper portion 3 includes an outward extension portion 32 extending radially outward from the outer peripheral surface of the inner stopper side wall portion 31. The inner stopper portion 3 also includes an inner stopper column portion 33 extending from the radially inner end of the inner stopper communication portion 30 toward the base end, an inward extension portion 34 extending radially inward from the base end of the inner stopper column portion 33, and an inner stopper shaft portion 35 extending from the inward extension portion 34 toward the tip and fitting with the dispensing portion 5.

[0033] The material of the inner stopper 3 is synthetic resin. The parts 30, 31, 32, 33, 34, and 35 of the inner stopper 3 are formed as a single unit. However, the inner stopper 3 may also be formed by combining at least one of these parts 30, 31, 32, 33, 34, and 35, which are formed separately. The material of the container body 2 is synthetic resin, but it may also be glass or the like.

[0034] The inner plug side wall portion 31 is a part that is attached to the inside of the opening portion 20 and the storage forming portion 4. The inner plug side wall portion 31 is, for example, cylindrical, specifically cylindrical. Furthermore, the inner plug side wall portion 31 extends from the outer diameter end of the inner plug communication portion 30 to both the tip side and the base end. The tip portion 310 of the inner plug side wall portion 31 is fitted into the storage forming portion 4. The base end portion 311 of the inner plug side wall portion 31 is fitted into the opening portion 20. An outward extension portion 32 extends from an axial position midway along the outer peripheral surface 313 of the inner plug side wall portion 31.

[0035] The outward projection 32 is a portion that abuts against the mouth portion 20 and also abuts against the storage forming portion 4. Furthermore, the outward projection 32 is, for example, annular. In this embodiment, the outward projection 32 comprises an annular rib 320 extending radially outward from the outer peripheral surface of the inner plug side wall portion 31, a base-side projection 321 extending toward the base end from the base end surface of the rib 320 facing the base end side, and a tip-side projection 322 extending toward the tip end from the tip surface of the rib 320 facing the tip side. The projections 321 and 322 are provided on the rib 320. In this configuration, even if the liquid chemical leaks from the gap between the inner plug side wall portion 31 and the mouth portion body portion 2020, the liquid chemical does not leak because it is in contact with the tip surface of the mounting body portion 421, thus improving liquid-stopping performance. Furthermore, even if the liquid chemical leaks from the gap between the tip 310 of the inner stopper side wall 31 and the mounting extension 420, the tip projection 322 abuts against the base end surface of the mounting extension 420, preventing leakage and improving liquid sealing performance. The base projection 321 and the tip projection 322 are each formed continuously around the entire circumference. The base projection 321 abuts against the tip surface of the first opening fitting portion 201 facing the tip side. The tip projection 322 abuts against the reservoir forming portion 4.

[0036] The inner plug connecting portion 30 is a part that can come into contact with the dispensing portion 5. This inner plug connecting portion 30 is formed continuously around the hole 300. The inner plug connecting portion 30 is composed of an outer wall portion 301 located radially outward and an inner wall portion 302 provided at the radially inward end of the outer wall portion 301.

[0037] The outer wall portion 301 extends radially inward from an axial position midway along the inner circumferential surface 312 of the inner plug side wall portion 31. The outer wall portion 301 is formed continuously around the entire circumference. In this embodiment, the radially inner edge of the outer wall portion 301 defines the hole 300 of the inner plug communication portion 30. The tip surface 3010 of the outer wall portion 301, facing the tip side, is inclined with respect to a plane perpendicular to the axial direction such that the radially inner surface is located closer to the base end.

[0038] The inner wall portion 302 extends inward from the inner end of the outer wall portion 301. The inner wall portion 302 is formed continuously around the circumference. The tip surface 3020 of the inner wall portion 302, facing the front end, extends perpendicularly to the axial direction. As shown in Figure 3C, the tip surface 3020 of the inner wall portion 302, together with the inner edge 3011 of the outer wall portion 301, forms a stepped portion 303 with an L-shaped cross-section. The stepped portion 303 is formed continuously around the circumference.

[0039] The central plug column 33 is, for example, a long plate-like structure extending along the axial direction (see Figure 3A). In this embodiment, four central plug column columns 33 are provided, but two, three, or five or more may be provided. The four central plug column columns 33 are arranged at equal intervals from each other in the circumferential direction.

[0040] The internal extension portion 34 is the part that connects the base ends of each central plug column portion 33. Specifically, the internal extension portion 34 is a cross-shaped portion that extends radially inward from the base end of each central plug column portion 33 and has an intersection portion 340 that intersects on the central axis of the central plug side wall portion 31. Furthermore, the internal extension portion 34 extends perpendicular to the axial direction.

[0041] The plug shaft portion 35 is a columnar extension, for example, cylindrical. The plug shaft portion 35 extends from the intersection 340 of the inner extension portion 34 towards the tip. In the axial direction, the plug shaft portion 35 extends to a position closer to the tip than the base end surface 3021 facing the base end of the inner wall portion 302. The plug shaft portion 35 is solid, but may have a cavity inside.

[0042] The storage forming section 4, together with the inner stopper section 3, comprises a storage body section 40 that forms a storage chamber R communicating with the inside of the container body section 2 via a hole 300 in the inner stopper communication section 30. The storage forming section 4 also comprises a storage communication section 41 provided on the storage body section 40, which has a hole 410 that communicates with the storage chamber R. Furthermore, the storage forming section 4 comprises a storage attachment section 42 provided on the storage body section 40 and attached to the opening section 20. The material of the storage forming section 4 is a transparent or translucent synthetic resin.

[0043] The storage body 40, together with the plug communication portion 30 and the tip portion 310 of the plug side wall portion 31 of the plug portion 3, forms a storage chamber R for measuring the amount of contents to be used in one go. The storage body 40 is cylindrical. Specifically, the base portion of the storage body 40 is cylindrical with a uniform outer diameter, while the tip portion of the storage body 40 is dome-shaped, extending towards the tip so that the outer diameter decreases towards the tip.

[0044] The storage communication section 41 is a cylindrical portion extending from the tip end of the storage body section 40 toward the tip end. The storage communication section 41 also comprises a storage tip section 411 that constitutes the tip end of the storage communication section 41, and a storage connecting section 412 that connects the storage tip section 411 and the storage body section 40.

[0045] As shown in Figure 3B, the base portion of the storage tip 411 is a large-diameter portion 414, which has a larger outer diameter than the small-diameter portion 413, which is the tip portion. Furthermore, the large-diameter portion 414 of the storage tip 411 has a larger inner diameter than the small-diameter portion 413.

[0046] The inner circumferential surface 4120 of the storage connection portion 412 is located radially outward from the inner circumferential surface 4110 of the storage tip portion 411. Furthermore, the inner circumferential surface 4120 of the storage connection portion 412, together with the inner circumferential surface 4110 of the storage tip portion 411, defines the hole 410 of the storage communication portion 41. On the inner circumferential side of the storage forming portion 4, the inner circumferential surface 4120 of the storage connection portion 412, together with the base end surface 4111 facing the base end side of the storage tip portion 411, forms a stepped portion 43 cut out in an L-shape in cross-section. The stepped portion 43 is located on the base end side of the inner circumferential surface 4110 of the storage tip portion 411. Also, the stepped portion 43 is formed continuously around the circumference.

[0047] The storage mounting portion 42 comprises a mounting extension portion 420 extending radially outward from the base end of the storage body portion 40, and a mounting body portion 421 extending towards the base end from the radially outer end of the mounting extension portion 420 (see Figure 3A). Two recesses 4210 and 4211 are provided on the inner circumferential surface of the mounting body portion 421, aligned in the axial direction. The storage mounting portion 42 is attached to the opening portion 20 by fitting the rib 2010 of the first opening fitting portion 201 into the recess 4210 on the base end side of the mounting body portion 421. The storage mounting portion 42 is attached to the inner plug portion 3 by fitting the outward extension portion 32 of the inner plug portion 3 into the recess 4211 on the tip side of the mounting body portion 421.

[0048] A dispensing passage 50 is formed in the dispensing section 5. The dispensing passage 50 is configured to allow the contents of the storage chamber R to be dispensed to the outside. The dispensing passage 50 can also communicate with the storage chamber R through the hole 410 of the storage communication section 41.

[0049] Furthermore, the dispensing section 5 includes a stopper opening / closing section 70 that opens and closes the hole 300 of the stopper communication section 30, and a storage opening / closing section 71 that opens and closes the hole 410 of the storage communication section 41. The dispensing section 5 is inserted into the storage chamber R through the hole 410 of the storage communication section 41. In addition, the dispensing section 5 is configured to be movable between a storage position (see Figures 4 and 5) where the stopper opening / closing section 70 opens the hole 300 of the stopper communication section 30 and the storage opening / closing section 71 closes the hole 410 of the storage communication section 41, and a dispensing position (see Figures 7 and 8) where the stopper opening / closing section 70 closes the hole 300 of the stopper communication section 30 and the storage opening / closing section 71 opens the hole 410 of the storage communication section 41. Furthermore, the dispensing section 5 is equipped with a dispensing opening / closing section 79 that prevents the contents of the storage chamber R from leaking out through the hole 410 of the storage communication section 41 when it is in the dispensing position.

[0050] In this embodiment, the dispensing section 5 includes a dispensing cylinder section 7 (see Figure 2). Specifically, in addition to the dispensing cylinder section 7, the dispensing section 5 includes a tip dispensing section 8 and a stopper section 9.

[0051] The dispensing cylinder portion 7 is a bottomed cylindrical member formed such that its interior forms a dispensing passage 50 and its tip end is an opening 511 (see Figure 3A). The dispensing cylinder portion 7 also includes a stopper opening / closing section 70 and a storage opening / closing section 71. Furthermore, the dispensing cylinder portion 7 also includes a dispensing opening / closing section 79. The dispensing cylinder portion 7 also includes a bottomed cylindrical dispensing cylinder body portion 72 with an opening 511 at its tip end, and a dispensing cylinder mounting portion 73 provided on the base end side of the dispensing cylinder body portion 72 and on the tip side of the stopper portion 3. The dispensing cylinder portion 7 is inserted into the storage chamber R through the hole 410 of the storage communication portion 41.

[0052] The dispensing cylinder body 72 comprises a cylinder tip 74, a cylinder base 75, and a cylinder connecting portion 76 that connects the cylinder tip 74 and the cylinder base 75. The inner circumferential surfaces of the cylinder tip 74, the cylinder base 75, and the cylinder connecting portion 76 are flush. The outer diameter of the cylinder base 75 is the same as the outer diameter of the cylinder connecting portion 76. The outer diameter of the cylinder tip 74 is smaller than the outer diameters of the cylinder base 75 and the cylinder connecting portion 76.

[0053] The tip portion 74 of the cylindrical body comprises a cylindrical body 740 and a tip rib 741 that protrudes radially outward from the outer circumferential surface of the cylindrical body 740. The tip rib 741 is integrally formed with the cylindrical body 740 so as to extend continuously around the circumference.

[0054] As shown in Figure 3C, the base end portion 75 of the cylindrical body comprises a cylindrical body 750, a base end rib 751 projecting radially outward from the outer circumferential surface 7501 of the base end portion 7500 of the cylindrical body 750, and a disc-shaped bottom plate 752 that closes the opening on the base end side of the cylindrical body 750. The base end rib 751 is formed integrally with the cylindrical body 750 so as to extend continuously around the circumference.

[0055] An L-shaped stepped portion 753 is formed by the outer circumferential surface 7501 and the base-side edge 7502 of the base end portion 7500 of the cylindrical body 750. The stepped portion 753 is formed continuously around the circumference. The stepped portion 753 and the base end rib 751 constitute the plug opening / closing portion 70.

[0056] The cylindrical body connecting portion 76 comprises a cylindrical body 760 and a connecting rib 761 that protrudes radially outward from the outer circumferential surface 7601 of the base end portion 7600 of the cylindrical body 760 (see Figure 3B). The cylindrical body 760 is provided with through holes 762 that penetrate through the thickness direction of the cylindrical body 760. In this embodiment, four through holes 762 are provided at equal intervals in the circumferential direction. The connecting rib 761 is formed integrally with the cylindrical body 760 so as to extend continuously around the circumference.

[0057] The outer circumferential surface 7601 of the base end portion 7600 of the cylindrical body 760 and the tip surface 7610 facing the tip side of the connecting rib 761 form an L-shaped stepped portion 763. The stepped portion 763 is formed continuously around the circumference. The stepped portion 763 also constitutes the storage opening / closing portion 71.

[0058] In the main body 72 of the dispensing cylinder described above, the dispensing opening / closing section 79, the storage opening / closing section 71, and the inner stopper opening / closing section 70 are arranged in order from the tip to the base (see Figure 3A).

[0059] The storage opening / closing section 71 includes a sliding section 6 that slides in the direction of movement of the storage communication section 41 when the dispensing section 5 moves between the storage position and the dispensing position (see Figure 3B). The sliding section 6 includes a notch 60 that reduces the thickness of the sliding section 6 in the direction of movement. In this embodiment, the connecting rib 761 includes the sliding section 6. The notch 60 of the connecting rib 761 is configured to reduce the thickness of the connecting rib 761 in the axial direction.

[0060] Furthermore, the sliding portion 6 protrudes outward from the outer peripheral surface 77 of the dispensing cylinder portion 7, intersecting the direction of movement, and the tip portion 61 in the protruding direction is configured to slide against the storage communication portion 41. The notch portion 60 is provided at the tip portion 61 of the sliding portion 6. Note that the notch portion 60 may be provided at a part other than the tip portion 61 of the sliding portion 6, for example, in the middle of the protruding direction of the sliding portion 6, that is, in the middle of the left-right direction of the sliding portion 6 in Figure 3B. Alternatively, the notch portion 60 may be provided at the base end of the sliding portion 6. In this embodiment, the thickness dimension in the direction of movement of the tip portion 61 of the sliding portion 6 is less than or equal to the axial dimension of the stepped portion 43, that is, the axial dimension of the inner peripheral surface 4120 of the storage connection portion 412.

[0061] In this embodiment, the notch 60 is provided in the middle of the thickness in the direction of movement of the tip 61 of the sliding part 6. As a result, the tip 61 of the sliding part 6 has sliding tip portions 611 and 612 that slide against the storage communication part 41 on one side and the other side in the direction of movement via the notch 60. The tip surface 610 of the sliding part 6 is composed of sliding tip surfaces 6110 and 6120 which are arranged on one side and the other side in the direction of movement via the notch 60. The sliding tip surfaces 6110 and 6120 slide against the inner circumferential surface of the storage communication part 41, and in this embodiment, against the inner circumferential surface 4120 of the storage connecting part 412.

[0062] The dispensing cylinder mounting portion 73 is cylindrical (see Figure 3A). The inner plug shaft portion 35 of the inner plug portion 3 fits into the dispensing cylinder mounting portion 73.

[0063] The tip dispensing section 8 is a component that fits into the opening 78 at the tip of the dispensing cylinder section 7. The tip dispensing section 8 also includes a spout section 80 with a dispensing hole 800 formed at the tip. Furthermore, the tip dispensing section 8 is connected to the spout section 80 at the base end to form a dispensing path 50, and includes a dispensing introduction section 81 with a larger diameter introduction hole 810 formed beyond the dispensing hole 800. The tip dispensing section 8 also includes a dispensing step section 82 formed between the spout section 80 and the dispensing introduction section 81. The tip dispensing section 8 is made of synthetic resin.

[0064] The spout portion 80 is a cylindrical member. In this embodiment, the spout portion 80 comprises a mouth insertion portion 802 and a mouth tip portion 803 provided on the tip side of the mouth insertion portion 802.

[0065] The spout fitting portion 802 is fitted into the opening 78 on the tip side of the dispensing cylinder portion 7. The spout tip portion 803 protrudes from the tip side of the dispensing cylinder portion 7. The outer diameter of the spout tip portion 803 is larger than that of the spout fitting portion 802. Also, the outer diameter of the spout tip portion 803 is approximately the same as the outer diameter of the tip rib 741 of the dispensing cylinder portion 7. Furthermore, the spout tip portion 803 abuts against the tip rib 741 of the dispensing cylinder portion 7 from the tip side. A dispensing hole 800 is formed in the radial center of the spout tip portion 803. In this embodiment, a dispensing hole 800 is formed in the radial center of the spout tip portion 803 and in the radial center of the spout fitting portion 802.

[0066] The tip surface 8030 facing the tip of the nozzle 803 serves as the application surface, spreading the contents dispensed from the dispensing hole 800 onto the scalp or other target object. The tip surface 8030 is formed continuously around the entire circumference. The tip surface 8030 is a flat surface, but it may also be a curved surface.

[0067] The dispensing introduction section 81 is a cylindrical member. The outer diameter of the dispensing introduction section 81 is the same as the outer diameter of the mouth fitting section 802. An introduction hole 810 is formed in the radial center of the dispensing introduction section 81. The diameter of the introduction hole 810 gradually increases from the tip side to the base side.

[0068] The dispensing step 82 is a cylindrical member. The outer diameter of the dispensing step 82 is the same as the outer diameter of the dispensing introduction section 81. The inner diameter of the tip edge of the dispensing step 82 is the same as the inner diameter of the base edge of the dispensing hole 800. The inner diameter of the base edge of the dispensing step 82 is the same as the inner diameter of the tip edge of the introduction hole 810. In other words, a connecting hole 820 is formed in the radial center of the dispensing step 82, connecting the dispensing hole 800 and the introduction hole 810. The diameter of the connecting hole 820 gradually increases from the tip side to the base side.

[0069] The stopper body 9 comprises a stopper tip portion 90 that is inserted into the dispensing hole 800 of the tip dispensing portion 8 and whose tip is movable in and out of the outlet, and a stopper opening / closing portion 91 provided on the base end side of the stopper tip portion 90 and formed to be larger in diameter than the stopper tip portion 90. Furthermore, as shown in Figures 5 to 7, the stopper body 9 is configured such that when the stopper tip portion 90 is retracted so as not to protrude out of the dispensing hole 800 of the tip dispensing portion 8, the stopper opening / closing portion 91 is spaced apart from the dispensing step portion 82 toward the base end and positioned toward the base end side of the dispensing introduction portion 81.

[0070] The plug tip 90 comprises an outer peripheral surface 900 formed in an annular shape around the direction of extension and retraction, and a plug recess 901 recessed in the outer peripheral surface 900 along the direction of extension and retraction (see Figure 2). In this embodiment, three plug recesses 901 are provided and are arranged at equal intervals in the circumferential direction. Note that there may be only one plug recess 901, or there may be two, four or more, etc.

[0071] The stopper opening / closing section 91 is the part that opens and closes the dispensing hole 800 from the base end side by moving toward and toward the dispensing step section 82 of the tip dispensing section 8. That is, the stopper opening / closing section 91 closes the dispensing hole 800 from the base end side by coming into contact with the dispensing step section 82, and opens the dispensing hole 800 from the base end side by moving toward the dispensing step section 82. In this embodiment, the stopper opening / closing section 91 comprises a shoulder section 92 connected to the tip of the stopper 90, a spring section 93 extending from the shoulder section 92 toward the base end side, and a base section 94 extending from the spring section 93 toward the base end side.

[0072] The shoulder portion 92 is cylindrical. The outer diameter of the shoulder portion 92 increases towards the base end. The spring portion 93 is a spring that extends between the shoulder portion 92 and the base portion 94. The base portion 94 is cylindrical. The outer diameter of the base portion 94 is larger than the outer diameter of the shoulder portion 92. In this embodiment, the stopper tip portion 90 can extend outward from the dispensing hole 800 of the tip dispensing portion 8 until the shoulder portion 92 abuts against the dispensing step portion 82 of the tip dispensing portion 8.

[0073] Each component of the plug body 9 is formed integrally. However, the plug body 9 may also be formed by combining at least one of these parts 90, 91, 92, and 93, which are formed separately. For example, the plug tip 90 and the plug opening / closing part 91 may be formed integrally, and the plug body 9 may be constructed by combining them with a spring, which is a separate component. In this configuration, the spring may or may not be connected to the plug opening / closing part 91. Furthermore, the plug body 9 may consist of the plug tip 90 and the plug opening / closing part 91, and may not include a spring.

[0074] In the dispensing section 5 described above, the dispensing passage 50 is composed of a dispensing hole 800, an introduction hole 810, and a connecting hole 820. The dispensing passage 50 can communicate with the storage chamber R via the hole 410 of the storage communication section 41. In this embodiment, the dispensing passage 50 can communicate with the storage chamber R via the through hole 762 of the dispensing cylinder section 7 and the hole 410 of the storage communication section 41.

[0075] Next, the dimensional relationships of each component of the dispensing section 5 will be described. The distance between the inner circumferential surface 801 of the dispensing hole 800 of the tip dispensing section 8 and the outer circumferential surface 900 of the stopper tip 90 of the stopper body section 9 is equal to the recess depth from the outer circumferential surface 902 of the stopper recess 901, or is greater than the recess depth from the outer circumferential surface 902 of the stopper recess 901.

[0076] As shown in Figure 3D, the ratio of the outer diameter (D1) of the stopper tip 90 to the inner diameter (D2) of the dispensing hole 800 is between 1.0:1.2 and 1.0:1.8. When the ratio of the outer diameter D1 of the stopper tip 90 to the inner diameter D2 of the dispensing hole 800 is less than 1.0:1.2, the amount of coating (discharge volume) decreases (the number of coatings increases). Also, when the ratio of the outer diameter D1 of the stopper tip 90 to the inner diameter D2 of the dispensing hole 800 is greater than 1.0:1.8, the amount of coating (discharge volume) increases, and there is a risk of the contents scattering.

[0077] Furthermore, the ratio of the radial dimension (D4) from the outer diameter of the stopper tip 90 to the edge 805 of the dispensing hole 800 to the radial dimension (D3) from the radial outer edge 804 of the mouth tip 803 to the edge 805 of the dispensing hole 800 is D4:D3 = 1.0:2.5 to 1.0:4.5. When the ratio of the radial dimension (D4) from the outer diameter of the stopper tip 90 to the edge 805 of the dispensing hole 800 to the radial dimension (D3) from the radial outer edge 804 of the mouth tip 803 to the edge 805 of the dispensing hole 800 is less than 1.0:2.5, the amount of coating (discharge amount) will increase, and there is a risk of the contents (liquid) scattering. Furthermore, when the ratio of the radial dimension (D4) from the outer diameter of the stopper tip 90 to the edge 805 of the dispensing hole 800 to the radial dimension (D3) from the radial outer edge 804 of the mouth tip 803 to the edge 805 of the dispensing hole 800 is greater than 1.0:2.5 to 1.0:4.5, the coating area becomes larger relative to the coating amount, which may cause uneven coating.

[0078] The ratio of the outer diameter (D1) of the stopper tip 90 to the radial dimension (D3) from the radial outer edge 804 of the mouth tip 803 to the hole edge 805 of the pouring hole 800 is between 1.0:0.5 and 1.0:1.4. When the ratio of the outer diameter D1 of the stopper tip 90 to the radial dimension D3 from the radial outer edge 804 of the mouth tip 803 to the hole edge 805 of the pouring hole 800 is less than 1.0:0.5, the stopper tip 90 may not extend or retract smoothly. Also, when the ratio of the outer diameter D1 of the stopper tip 90 to the radial dimension D3 from the radial outer edge 804 of the mouth tip 803 to the hole edge 805 of the pouring hole 800 is greater than 1.0:1.4, the coating area becomes larger relative to the coating amount, which may result in uneven coating.

[0079] The outer diameter D1 of the stopper tip 90 is, for example, 2.8 mm. The inner diameter D2 of the dispensing hole 800 is, for example, 4.1 mm. The radial dimension D3 from the radial outer edge 804 of the mouth tip 803 to the hole edge 805 of the dispensing hole 800 is, for example, 2.8 mm.

[0080] The inner cap 11 is provided so as to be screwable onto the male thread 2021 of the second opening fitting portion 202 of the container body portion 2 (see Figure 3A). The inner cap 11 also comprises a cylindrical side portion 110 and a substantially disc-shaped upper portion 111 provided at the tip of the side portion 110. A cap rib 1100 projecting radially outward is formed around the outer circumferential surface of the base end of the side portion 110. Inside the central part of the upper portion 111, there is a pressing portion 112 that presses against the tip dispensing portion 8 and an engaged portion 113 that is positioned radially outward from the pressing portion 112 and fits into and engages with the dispensing cylinder portion 7 and the tip dispensing portion 8.

[0081] The engaged portion 113 is formed in a cylindrical shape that surrounds the dispensing cylinder portion 7 and the tip dispensing portion 8 from the outer diameter. A bulge portion 1130 that protrudes radially inward is formed at the base end of the engaged portion 113. When the inner cap 11 is closed, the pressing portion 112 pushes the tip dispensing portion 8 toward the base end, pushing the dispensing portion 5 into the storage forming portion 4.

[0082] In this embodiment, the inner cap 11 is provided with a side projection 114 extending from the base end of the side portion 110 toward the base end (see Figure 2). There are multiple side projections 114, specifically four. The four side projections 114 are provided at equal intervals in the circumferential direction. Furthermore, the side projections 114 engage with the shoulder projection 221 of the container body 2 when the inner cap 11 is screwed into the male screw 2021 of the second mouth fitting portion 202 of the container body 2.

[0083] The outer cap 12 comprises a cylindrical side portion 120 and a substantially disc-shaped upper portion 121 provided at the tip of the side portion 120. A recess 1200, which is radially recessed outward, is formed all around the inner circumferential surface of the side portion 120 (see Figure 3A). The outer cap 12 is fixed to the inner cap 11 with the recess 1200 of the outer cap 12 engaged with the cap rib 1100 of the inner cap 11. The outer cap 12 may be formed integrally with the inner cap 11.

[0084] The method of using the quantitative dispensing container 1 is described below. First, the liquid medicine or the like is placed in the container body 2, and the inner stopper 3, to which the dispensing part 5 has been attached in advance, is attached to the mouth 20 of the container body 2. Then, the storage forming part 4 is attached to the mouth 20. At this time, the inner stopper shaft 35 of the inner stopper 3 is fitted into the dispensing cylinder attachment part 73 of the dispensing cylinder part 7.

[0085] Furthermore, an inner cap 11 with the outer cap 12 already attached is attached to the mouth 20 of the container body 2. When the inner cap 11 with the outer cap 12 attached is attached to the mouth 20, the engaged portion 113 of the inner cap 11 is pressed against the tip 803 of the dispensing portion 8, causing it to elastically deform slightly and open radially outward. When the bulging portion 1130 of the engaged portion 113 overcomes the tip 803 of the mouth and the tip rib 741 of the tip 74 of the cylindrical body, the elastic deformation of the engaged portion 113 returns to its original state, and the bulging portion 1130 is positioned below the tip 803 of the mouth and the tip rib 741 of the tip 74 of the cylindrical body (see Figure 3A). At this time, the pressing portion 112 of the inner cap 11 pushes the dispensing portion 5 into the storage forming portion 4, that is, moves the dispensing portion 5 toward the inside of the storage forming portion 4.

[0086] Next, in order to take the liquid medicine out of the container body 2 and use it, when the inner cap 11, which is fixed to the outer cap 12, is removed from the container body 2, the dispensing part 5 is pulled out from the inner stopper part 3 and the storage forming part 4. Specifically, since the tip of the mouth 803 and the tip rib 741 of the tip of the cylinder body 74 are locked to the bulging part 1130 of the engaged part 113 of the inner cap 11, the dispensing part 5 moves toward the tip side relative to the inner stopper part 3 and the storage forming part 4 as the inner cap 11 moves. As a result, as shown in Figures 4A and 4B, the storage opening / closing part 71 of the dispensing cylinder 7 closes the hole 410 of the storage communication part 41 and makes tight contact with the stepped part 43, sealing the hole 410. Specifically, as the dispensing section 5 moves toward the tip, the tip end of the sliding section 6 of the storage opening / closing section 71 reaches a position where it is radially aligned with the base end of the storage connecting section 412 of the storage forming section 4. From there, the tip surface 610 of the sliding section 6 slides against the inner circumferential surface 4120 of the storage connecting section 412 until the tip edge 613 of the sliding section 6 contacts the base end surface 4111 of the storage tip section 411. In other words, the tip surface 610 of the sliding section 6 slides against the inner circumferential surface 4120 of the storage connecting section 412 in order for the storage opening / closing section 71 to make close contact with the stepped section 43. At this time, the plug opening / closing section 70 of the dispensing cylinder section 7 moves away from the stepped section 303 of the plug connecting section 30, and the dispensing section 5 moves to the storage position.

[0087] Furthermore, when the inner cap 11 is removed from the container body 2, the engaged portion 113 of the inner cap 11 elastically deforms and opens outward, the bulging portion 1130 detaches from the tip rib 741 of the mouth tip 803 and the tip 74 of the cylindrical body tip, and the inner cap 11 is removed.

[0088] Then, when the container body 2 is turned upside down in this state, the liquid medicine inside the container body 2 flows into the storage chamber R, passing between the inner stopper column portions 33 that are arranged circumferentially around the inner stopper portion 3, filling it, and a certain amount of liquid medicine is measured out. In this way, when the dispensing portion 5 is in the storage position, the storage opening / closing portion 71 of the dispensing cylinder portion 7 closes the hole 410 of the storage communication portion 41, so the liquid medicine inside the dispensing cylinder portion 7 does not leak out. In this embodiment, the tip surface 3010 of the outer wall portion 301 of the inner stopper communication portion 30, which faces the tip side, is flared diagonally toward the tip side relative to the hole 300 of the inner stopper communication portion 30, so when the container body 2 is turned upside down, the liquid medicine reliably fills the storage chamber R.

[0089] Next, the stopper portion 9 of the container body 2 is brought close to the user's head, and the tip portion 90 of the stopper portion 9 is used to press against the user's head. As shown in Figure 5, the tip portion 90 of the stopper is then pushed down into the dispensing cylinder portion 7, and the tip portion 90 retracts toward the inside of the dispensing cylinder portion 7. Specifically, the tip portion 90 of the stopper is pushed down into the dispensing hole 800, so that it does not protrude out of the dispensing hole 800.

[0090] Furthermore, when the user's head is pressed by the stopper tip 90 of the stopper body 9 and the spout tip 803 of the tip dispensing part 8, the stopper body 9, tip dispensing part 8, and dispensing cylinder 7 move toward the base end, as shown in Figure 6. At this time, the tip surface 610 of the sliding part 6 of the storage opening / closing part 71 slides against the inner circumferential surface 4120 of the storage connecting part 412 until the tip end of the sliding part 6 of the storage opening / closing part 71 reaches a position where it is radially aligned with the base end of the storage connecting part 412 of the storage forming part 4. Also, this movement causes the storage opening / closing part 71 of the dispensing cylinder 7 to move away from the stepped part 43 of the storage communication part 41, and the storage opening / closing part 71 is released from its close contact with the stepped part 43.

[0091] The movement of the stopper body 9, the tip dispensing portion 8, and the dispensing cylinder portion 7 toward the base end is completed when the stopper opening / closing portion 70 of the dispensing cylinder portion 7 closes the hole 300 of the stopper communication portion 30 and makes close contact with the stepped portion 303, as shown in Figure 7. Specifically, the movement is completed when the base-side edge 7502 of the base end portion 7500 of the cylinder body base end portion 75 comes into contact with the tip surface 3020 of the inner wall portion 302 of the stopper communication portion 30. Specifically, as the dispensing portion 5 moves toward the base end, the outer circumferential surface of the base end portion 7500 slides against the stepped portion 303 from the position where the base-side edge 7502 of the base end portion 7500 of the cylinder body base end portion 75 is radially aligned with the tip end of the stepped portion 303 until this edge 7502 comes into contact with the tip surface 3020. In other words, the outer circumferential surface of the base end portion 7500 slides against the stepped portion 303 in order for the inner plug opening / closing portion 70 to be in close contact with the stepped portion 303.

[0092] Once this movement is complete, the chemical solution can be dispensed to the outside from the dispensing passage 50. Specifically, the chemical solution that filled the storage chamber R flows out through the hole 410 of the storage communication section 41, the through-hole 762 of the dispensing cylinder section 7, and the dispensing passage 50 to the outside.

[0093] Furthermore, when the tip 90 of the stopper body 9 separates from the scalp, as shown in Figure 8, the tip 90 extends from inside the dispensing cylinder 7 to the outside. In this way, when the dispensing section 5 is in the dispensing position, the inner stopper opening / closing section 70 closes the hole 300 of the inner stopper communication section 30, so that the liquid medicine in the container body 2 does not flow into the storage chamber R, and no excess liquid medicine comes out of the container body 2, allowing a fixed amount of liquid medicine to be dispensed to the outside.

[0094] After using the quantitative dispensing container 1, reattach the caps 11 and 12 to the container body 2, and store the container with the dispensing section 5 in the dispensing position, where the inner stopper opening / closing section 70 of the inner stopper communication section 30 closes the hole 300 (see Figure 3A).

[0095] In the above quantitative dispensing container 1, the sliding part 6 is equipped with a notch 60, so the thickness of the part of the sliding part 6 that slides against the storage communication part 41 is reduced in the direction of movement. Therefore, the part of the sliding part 6 that slides against the storage communication part 41 becomes more easily deformed when sliding, and the resistance to sliding can be suppressed. Consequently, the resistance when moving the dispensing part 5 can be suppressed.

[0096] In the quantitative dispensing container 1 of this embodiment, a notch 60 is provided in the protruding tip 61 of the sliding part 6. This makes the tip 61, which is the part of the thinned sliding part 6 that slides against the storage communication part 41, more easily deformable, thereby suppressing sliding resistance. Consequently, resistance when moving the dispensing part 5 can be suppressed.

[0097] Furthermore, in the quantitative dispensing container 1 of this embodiment, a notch 60 is provided in the middle of the thickness in the direction of movement of the tip 61 of the sliding part 6. Therefore, in both the case of movement to one side and the case of movement to the other side in the direction of movement, the thinned sliding tip 611, 612 is easily deformed, and sliding resistance can be suppressed. Accordingly, resistance when moving the dispensing part 5 to one side can be suppressed, and resistance when moving the dispensing part 5 to the other side can also be suppressed.

[0098] Furthermore, in the quantitative dispensing container 1 of this embodiment, when the tip 90 of the stopper body 9 is retracted into the dispensing hole 800 of the tip dispensing section 8, the stopper opening / closing section 91 is positioned on the base end side of the dispensing introduction section 81, so that the large-diameter stopper opening / closing section 91 extends from the dispensing introduction section 81 towards the base end. Therefore, when the tip 90 of the stopper is retracted into the dispensing hole 800, the contents that have entered the dispensing passage 50 smoothly enter the introduction hole 810 of the dispensing introduction section 81, making it easier to dispense the contents from the dispensing hole 800.

[0099] Furthermore, in the quantitative dispensing container 1 of this embodiment, the ratio of the outer diameter D1 of the stopper tip 90 to the inner diameter D2 of the dispensing hole 800 is 1.0:1.2 to 1.0:1.8, and D4:D3 = 1.0:2.5 to 1.0:4.5. Therefore, when applying the contents dispensed from the dispensing hole by spreading it at the tip of the opening, it is possible to dispense an appropriate amount of contents while spreading and applying the dispensed contents without scattering.

[0100] It should be noted that the quantitative dispensing container of the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention.

[0101] In the above embodiment, the storage opening / closing section 71 was provided with a sliding section 6, but the inner plug opening / closing section 70 may also be provided with a sliding section 6 that slides in the direction of movement to the inner plug communication section 30, or both the inner plug opening / closing section 70 and the storage opening / closing section 71 may each be provided with a sliding section 6. That is, at least one of the opening / closing sections of the inner plug opening / closing section 70 and the storage opening / closing section 71 should be provided with a sliding section 6 that slides in the direction of movement to at least one of the communication sections of the inner plug communication section 30 and the storage communication section 41 when the dispensing section 5 moves between the storage position and the dispensing position. With such a configuration, by providing a notch 60 in the sliding section 6, the thickness in the direction of movement of the portion of the sliding section 6 that slides against the inner plug communication section 30 and the storage communication section 41 is reduced. Therefore, the portion of the sliding section 6 that slides against the inner plug communication section 30 and the storage communication section 41 becomes more easily deformed when sliding, and the resistance to sliding can be suppressed. Therefore, resistance when moving the dispensing section 5 can be suppressed. The dispensing opening / closing section 79 may also be equipped with a sliding section 6 that slides in the direction of movement.
