Description

Technical Field

[0001] The present invention relates to a dispenser with a tray.

Background Art

[0002] Conventionally, as shown in Patent Document 1 below, for example, a pump mechanism having a discharge nozzle (stem) disposed at the mouth of a container body so as to be movable downward in an upwardly biased state, and a tray that is attached to the upper end of the discharge nozzle and communicates with the inside of the discharge nozzle through a discharge hole and stores the contents discharged from the discharge nozzle are known. The pump mechanism further includes a piston that moves up and down in association with the discharge nozzle, and a cylinder in which the piston is fitted so as to be slidable up and down.

[0003] In the dispenser with a tray configured as described above, by moving the discharge nozzle downward by pressing down the tray, the piston can be lowered with respect to the cylinder. As a result, the contents in the cylinder can be discharged into the tray through the discharge nozzle and the discharge hole. Therefore, it is possible to store the contents discharged into the tray. Therefore, various uses can be made using the contents accumulated in the tray. For example, by dipping an application tool such as a puff into the contents accumulated in the tray, an application method such as applying the contents through the application tool can be performed.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the conventional dispenser with a receiving tray described above, the discharge hole is formed in a round shape when viewed from above. Therefore, when the receiving tray is pressed down, the contents that have passed through the discharge nozzle tend to concentrate and flow into the discharge hole, causing the contents to be discharged forcefully from the discharge hole. As a result, there is a risk that the contents may scatter into the surroundings (for example, liquid splashing may occur). In particular, one might consider pressing down the tray without covering the discharge hole with an application tool or the like to check the amount of contents being dispensed, but in this case, the aforementioned problems are likely to occur significantly. Furthermore, there was a risk that the contents would forcefully spray out of the discharge hole, overflow the tray, and be dispensed into the surrounding area.

[0006] The present invention has been made in view of these circumstances, and its purpose is to provide a dispenser with a tray that can appropriately dispense contents into a tray while suppressing unintended scattering of the contents. [Means for solving the problem]

[0007] (1) The discharger with a tray according to the present invention comprises a pump mechanism attached to the mouth of a container body containing contents, having a stem that is arranged to be movable downward in an upward biased state, and a tray attached to the upper end of the stem, having a discharge hole formed therein that communicates with the inside of the stem, wherein the tray has a fitting cylinder portion fitted to the upper end of the stem, and an annular tray body that is arranged coaxially with the central axis of the stem and integrally formed to close the upper end opening of the fitting cylinder portion, and extends radially outward from the upper end of the fitting cylinder portion, the discharge hole is formed in the tray body so as to penetrate the tray body vertically, an inner member is provided inside the discharge hole, and the discharge hole is formed in an annular shape that extends continuously in the circumferential direction around the inner member so as to surround the inner member. The upper end of the inner member has an enlarged diameter portion that protrudes radially outward in a direction intersecting the central axis when viewed from the direction of the central axis, and is positioned above the upper end opening of the stem. The enlarged diameter portion is supported by the fitting cylinder portion via a plurality of connecting ribs. The plurality of connecting ribs are located between the receiving tray body and the upper end opening of the stem, and are positioned within a space that communicates the inside of the stem and the inside of the discharge hole, and contact the upper end opening edge of the stem from above. The inner member is integrally assembled with the fitting cylinder portion via the plurality of connecting ribs, and the receiving tray is positioned relative to the stem by the contact of the plurality of connecting ribs with the upper end opening edge of the stem. It is characterized by the following:

[0008] According to the discharger with a receiving tray of the present invention, the pump mechanism can be activated by pressing down on the receiving tray against the upward biasing force of the stem and then releasing it. This makes it possible to discharge the contents from inside the stem towards the receiving tray, or to draw the contents back into the stem from inside the container body after discharge, in preparation for the next discharge. When the contents are discharged by the operation of the pump mechanism, the contents can be moved upward within the stem toward the receiving tray body, and the contents can be discharged from the upper end opening of the stem through the discharge hole to the upper surface of the receiving tray body. This allows the contents to be accumulated on the upper surface of the receiving tray body, for example, enabling a variety of uses for the contents.

[0009] In particular, unlike conventional designs, the discharge holes formed in the tray body are formed in an annular shape that extends continuously in the circumferential direction of the inner member, surrounding the inner member. This allows the contents discharged from the upper end opening of the stem to be evenly distributed throughout the discharge holes, rather than being locally concentrated in a part of the discharge hole. Therefore, the force of the discharge of the contents can be suppressed, and the contents can be discharged evenly and at a controlled speed from the entire discharge hole onto the upper surface of the tray body. This allows for the proper dispensing of the contents onto the top surface of the tray while suppressing unintended scattering of the contents, and also enables the contents to slowly accumulate on the top surface of the tray. Furthermore, even if the tray is pressed down without covering the dispensing hole with an application tool, the ejection of the contents can be suppressed, making it possible to dispense only the appropriate amount of contents while checking the amount being dispensed. Furthermore, when the receiving tray is pressed down, a portion of the contents discharged upward (towards the receiving tray body) from the upper end opening of the stem can be brought into contact with the enlarged diameter section from below. Therefore, the direction of the contents' flow can be changed by contact with the enlarged diameter section. Consequently, it is possible to prevent the entire contents discharged from inside the stem from reaching the discharge hole in a straight line. Therefore, after the force of the contents is weakened by contact with the enlarged diameter section, the contents can be discharged while being dispersed throughout the entire annular discharge hole. Consequently, the effects described above can be achieved even more effectively.

[0010] (2) The inner member may be arranged coaxially with the central axis and formed in an axial shape that extends in the vertical direction.

[0011] In this case, the discharge hole can be positioned directly above the upper end opening of the stem so that its center is coaxial with the central axis of the stem, and the discharge hole can be formed, for example, in an annular shape. As a result, the contents can be discharged evenly and with reduced discharge speed from the entire discharge hole onto the upper surface of the receiving tray body.

[0014] ( 3 The cross-sectional area of ​​the flow path around the entire circumference of the discharge hole may be larger than the cross-sectional area of ​​the flow path at the upper end opening of the stem.

[0015] In this case, since the cross-sectional area of ​​the flow path at the discharge hole is larger than the cross-sectional area of ​​the flow path at the upper end opening of the stem, the discharge speed of the contents can be further suppressed as they pass through the discharge hole.

[0016] ( 4 The fitting cylinder portion protrudes upward from the upper end of the stem so that the receiving plate body is positioned at a distance above the stem. 、 The cross-sectional area of ​​the flow path in the aforementioned space may be larger than the cross-sectional area of ​​the flow path at the upper end opening of the stem.

[0017] In this case, the contents discharged from the upper end opening of the stem can be allowed to flow into the space before being guided to the discharge hole. Moreover, since the flow path cross-sectional area of ​​the space is larger than the flow path cross-sectional area of ​​the upper end opening of the stem, the pressure of the contents can be reduced when they flow into the space, further suppressing the discharge speed. [Effects of the Invention]

[0018] According to the present invention, a dispenser with a receiving tray can be made that can appropriately dispense the contents into the receiving tray while suppressing unintended scattering of the contents. [Brief explanation of the drawing]

Embodiments for Carrying out the Invention

[0020] Hereinafter, embodiments of a dispenser with a tray according to the present invention will be described with reference to the drawings. As shown in FIG. 1, a dispenser 1 with a tray of the present embodiment (hereinafter, simply referred to as dispenser 1) includes a pump mechanism 11 having a stem 10, a mounting cap 12 mounted on a mouth portion 3 of a container body 2 in which a content is accommodated, and a pump mechanism 11 is combined with the mouth portion 3 of the container body 2, a tray 14 mounted on the stem 10 and having a discharge hole 13 for discharging the content, and an overcap 15 covering the tray 14. In addition, each component of the dispenser 1 is a molded product using a synthetic resin material unless otherwise specified. The content is not particularly limited, and examples thereof include liquid contents such as lotion and cosmetics.

[0021] In FIG. 1, the pump mechanism 11 including the stem 10, the mounting cap 12, and the tray 14 are arranged coaxially with the container axis O of the container body 2. Hereinafter, the tray 14 side is referred to as upward and the container body 2 side is referred to as downward along the container axis O, and the direction along the container axis O is referred to as the vertical direction. Further, in a plan view seen from the vertical direction, the direction intersecting the container axis O is referred to as the radial direction, and the direction orbiting around the container axis O is referred to as the circumferential direction.

[0022] (Container body) The container body 2 is formed in a bottomed cylindrical shape in which a mouth portion 3, a shoulder portion 4, a body portion 5, and a bottom portion (not shown) are continuously provided in this order from above. A male screw portion 6 is formed on the outer peripheral surface of the mouth portion 3 of the container body 2.

[0023] (Mounting cap) The mounting cap 12 comprises a mounting cylinder 20 that surrounds the mouth 3 of the container body 2 from the radial outside, an annular cap top wall 21 that protrudes radially inward from the upper end of the mounting cylinder 20, a guide cylinder 22 that extends upward from the cap top wall 21 and surrounds the stem 10 from the radial outside, an annular connecting wall 23 that protrudes radially outward from the mounting cylinder 20, and a decorative cylinder 24 that surrounds the mouth 3 of the container body 2, the mounting cylinder 20, and the guide cylinder 22 from the radial outside.

[0024] The inner circumferential surface of the mounting cylinder 20 has a female threaded portion 25 that screws onto the male threaded portion 6 formed on the mouth 3 of the container body 2. As a result, the mounting cap 12 is attached to the mouth 3 of the container body 2 by screwing it in through the screw connection between the male threaded portion 6 and the female threaded portion 25. However, the method of attaching the cap 12 is not limited to screwing; for example, it may be attached to the mouth 3 of the container body 2 by an undercut fitting.

[0025] The guide tube 22 plays a role in guiding the vertical movement of the receiving plate 14. The guide tube 22 is formed to extend upward from the inner peripheral edge of the cap top wall 21, and is formed as a cylindrical shape with an outer diameter smaller than the outer diameter of the mounting tube 20. In the illustrated example, the guide tube 22 is formed to have a length approximately the same as the vertical length of the mounting tube 20.

[0026] The connecting wall 23 is formed to protrude radially outward from the outer circumferential surface of the portion of the mounting cylinder 20 located above the female thread portion 25. In particular, the connecting wall 23 is formed so that its outer circumferential edge is located radially outward from the outer circumferential edge of the receiving tray body 91, which will be described later and constitutes the receiving tray 14.

[0027] The decorative tube 24 is connected to the outer peripheral edge of the connecting wall 23, and is formed such that its upper end is located above the guide tube 22 and its lower end is located near the shoulder portion 4 of the container body 2. As a result, the decorative tube 24 is formed to surround the mouth portion 3 of the container body 2, the mounting tube 20, and the guide tube 22 from the radial outside at a certain distance. The decorative tube 24 is formed so that its inner diameter is larger than the outer diameter of the receiving tray 14 body. As a result, when the receiving tray 14 is pressed down, the receiving tray body 91 does not come into contact with the decorative tube 24. The mounting cap 12, configured as described above, is formed in a double-tube shape by including a decorative tube 24.

[0028] (Pump mechanism) The pump mechanism 11 includes a cylinder 30, a valve member 40, a stem 10, a piston guide 50, a piston 60, a support cylinder 70, and a biasing member 80.

[0029] (Cylinder) The cylinder 30 is formed in a cylindrical shape having a cylinder circumferential wall 31 and is arranged coaxially with the container axis O. The cylinder circumferential wall 31 is formed with an outer diameter smaller than the inner diameter of the mouth 3 of the container body 2, and a predetermined gap is secured between the cylinder circumferential wall 31 and the mouth 3 of the container body 2. At the lower end of the cylinder circumferential wall 31, a tapered cylinder 32 with a cross-sectional tapered shape that gradually decreases in diameter towards the bottom is formed.

[0030] An annular flange portion 33 is formed at the upper end of the cylinder peripheral wall 31, projecting radially outward. The flange portion 33 is positioned on the upper opening edge of the mouth portion 3 of the container body 2 via a packing 34, and is sandwiched vertically between the flange portion 3 and the upper opening edge of the mouth portion 3 by a mounting cap 12 that is fitted onto the mouth portion 3 of the container body 2.

[0031] As a result, the entire pump mechanism 11, including the cylinder 30, is attached to the opening 3 of the container body 2 via the mounting cap 12. The cylinder 30 extends downward from the opening 3 of the container body 2 and is attached to the opening 3 of the container body 2 via the mounting cap 12 so as to fit inside the container body 2. The cylinder circumferential wall 31 opens upward through the inside of the cap top wall 21. As a result, the stem 10 is inserted into the inside of the cylinder circumferential wall 31 from above.

[0032] A flow hole 35 for the contents to flow is formed inside the tapered cylinder 32. Furthermore, a connecting cylinder 36 extending downward is integrally formed on the tapered cylinder 32. The upper end of a pipe 37 for drawing up the contents is fitted inside the connecting cylinder 36. In this way, the cylinder 30 and the pipe 37 are integrated together. The lower end opening of the pipe 37 is located inside the bottom of the container body 2.

[0033] (Valve member) The valve member 40 comprises a lower valve body 41 and a valve stem 42, and is responsible for switching between communication and blockage between the inside of the container body 2 and the inside of the cylinder 30. The valve member 40 is arranged coaxially with the container shaft O and is positioned to be vertically movable within the cylinder 30. The lower valve body 41 is positioned inside the lower end of the cylinder circumferential wall 31 and is capable of moving toward and away from the inner circumferential surface of the tapered cylinder 32 as the valve member 40 moves up and down. Specifically, the lower valve body 41 functions as a check valve that maintains the flow hole 35 closed by contacting the inner circumferential surface of the tapered cylinder 32 when the cylinder 30 is pressurized, and opens the flow hole 35 by moving away from the inner circumferential surface of the tapered cylinder 32 when the pressure inside the cylinder 30 is reduced.

[0034] As a result, the lower valve body 41 restricts the backflow of the contents of the cylinder 30 into the container body 2 through the flow hole 35 when the cylinder 30 is pressurized, and allows the contents of the container body 2 to flow into the cylinder 30 through the flow hole 35 when the pressure inside the cylinder 30 is reduced. However, the lower valve body 41 is not limited to the configuration described above, and may be a valve structure other than the above configuration, such as a multi-valve body like a three-point valve, or a ball valve. The valve stem 42 is formed in a cylindrical shape that extends upward from the lower valve body 41.

[0035] (Stem) The stem 10 is erected inside the mouth 3 of the container body 2 so as to be movable downward while biased upward. The stem 10 is formed in a cylindrical shape that extends vertically and is positioned inside the cap top wall 21 and inside the cylinder peripheral wall 31. Before the receiving tray 14 is pressed down, the stem 10 is positioned so that its upper end protrudes above the guide tube 22 and decorative tube 24 of the mounting cap 12, and its lower end is housed within the cylinder 30. The lower end of the stem 10 is an enlarged diameter portion 10a that widens radially outward. As a result, the stem 10 is formed in a two-stage cylindrical shape with a change in outer diameter in the vertical direction.

[0036] As shown in Figure 2, longitudinal ribs 10b projecting radially inward are formed on the inner circumferential surface of the upper end of the stem 10 at circumferential intervals. Therefore, the portion of the inner part of the upper end of the stem 10 excluding these longitudinal ribs 10b functions as the upper end opening 10c. Accordingly, the flow path cross-sectional area of ​​the stem 10 is defined by the diameter D1 of the upper end opening 10c of the stem 10 shown in Figure 2. However, the longitudinal rib 10b is not essential and does not need to be included.

[0037] (Piston guide) As shown in Figure 1, the piston guide 50 is positioned coaxially with the vessel axis O, below the stem 10. The piston guide 50 comprises a guide cylinder 51 and an annular guide flange 52 projecting radially outward from the lower end of the guide cylinder 51.

[0038] The upper end of the guide cylinder 51 is fitted inside the portion of the stem 10 located above the enlarged diameter portion 10a. This allows the piston guide 50 to be integrally assembled with the stem 10 and to move up and down with the stem 10. The guide cylinder 51 is assembled to the stem 10 such that its lower end is located below the enlarged diameter portion 10a of the stem 10.

[0039] An annular lip portion 53 is formed on the inner circumferential surface of the lower end of the guide cylinder 51, projecting radially inward and making vertically slidable contact with the valve stem 42 of the valve member 40. As a result, the piston guide 50 is able to move vertically while maintaining a proper seal between itself and the valve stem 42, and is able to move vertically while its posture is stabilized by the valve stem 42. Similarly, the valve member 40 is able to move vertically while its posture is relatively stable by the piston guide 50. In the portion of the guide tube 51 located below the part fitted inside the stem 10, multiple first through holes 54 are formed at circumferential intervals, passing through the guide tube 51 radially.

[0040] The guide flange 52 supports the piston 60 from below. The guide flange 52 has multiple second through holes 55 that penetrate vertically and are spaced apart in the circumferential direction. This allows the contents of the cylinder 30 to be supplied into the stem 10 through the second through holes 55 of the guide flange 52 and the first through holes 54 of the guide cylinder 51. The piston guide 50, configured in this way, works in cooperation with the piston 60 to function as the upper valve body in the pump mechanism 11.

[0041] (piston) The piston 60 is linked to the up-and-down movement of the stem 10 and is fitted inside the cylinder 30 so as to be able to slide up and down. The piston 60 comprises an outer piston cylinder 61, an inner piston cylinder 62, and a connecting cylinder 63, and is positioned coaxially with the container axis O, between the enlarged diameter portion 10a of the stem 10 and the guide flange 52.

[0042] The outer piston cylinder 61 is formed in a tapered shape, gradually increasing in diameter from the central part in the vertical direction upward and downward, and is equipped with lip portions located at both ends in the vertical direction. The lip portions are in close sliding contact with the inner surface of the cylinder circumferential wall 31. This ensures a predetermined sealing performance between the lip portions and the inner surface of the cylinder circumferential wall 31. Furthermore, the outer piston cylinder 61 is positioned to block the air holes 64 formed in the cylinder peripheral wall 31 when the receiving tray 14 is not being pressed down.

[0043] The inner piston cylinder 62 is positioned between the outer piston cylinder 61 and the guide cylinder 51. The upper end of the inner piston cylinder 62 enters the inside of the enlarged diameter portion 10a of the stem 10 from below and is in close sliding contact with the inner circumferential surface of the enlarged diameter portion 10a. The lower end of the inner piston cylinder 62 is seated on the guide flange 52 so as to be able to move away from it from above. As a result, the inner piston cylinder 62 can switch between communicating with and blocking communication between the portion of the cylinder 30 located below the piston 60 (hereinafter referred to as the lower chamber 38) and the first through-hole 54 in the piston guide 50. The connecting cylinder 63 connects the inner circumferential surface of the outer piston cylinder 61 and the outer circumferential surface of the inner piston cylinder 62, and extends continuously along its entire length in the circumferential direction.

[0044] (Support tube) The support cylinder 70 functions as a retaining member for each component located inside the cylinder 30, such as the piston 60. The support cylinder 70 is mounted inside the upper end of the cylinder peripheral wall 31 and is positioned coaxially with the container axis O. The support cylinder 70 comprises a support cylinder body 71 fitted inside the cylinder peripheral wall 31, an annular flange portion 72 protruding radially outward from the upper end of the support cylinder body 71, and an upper cylinder 73 protruding further upward from the upper end of the support cylinder body 71.

[0045] The support cylinder body 71 is formed to surround the enlarged diameter portion 10a of the stem 10 from the radial outside. As a result, the outer piston cylinder 61 is positioned below the support cylinder body 71. Therefore, the piston 60 and piston guide 50 are prevented from coming out upward by the support cylinder body 71. The flange portion 72 is positioned on the flange portion 33 of the cylinder 30 and is sandwiched vertically between it and the flange portion 33 by the cap top wall 21.

[0046] The upper cylinder 73 has a smaller diameter than the support cylinder body 71 and is positioned above the enlarged portion 10a of the stem 10. As a result, the upper cylinder 73 surrounds the portion of the stem 10 located above the enlarged portion 10a from the radial outside. This prevents the upper cylinder 73 from coming out of the cylinder 30 upward.

[0047] (Biasing member) The biasing member 80 is, for example, a coil spring positioned in a compressed state, and biases the stem 10 upward via the piston guide 50. The biasing member 80 is positioned within the lower chamber 38 of the cylinder 30, surrounding the valve member 40 from the radial outside, and is also positioned coaxially with the container axis O. The biasing member 80 is positioned between the longitudinal ribs protruding from the inner circumferential surface of the cylinder peripheral wall 31 and the piston guide 50, in a state of vertical compression. In this embodiment, the biasing member 80 is, for example, a metal coil spring. However, it is not limited to this case, and the biasing member 80 may also be a coil spring made of synthetic resin.

[0048] (Tray) As shown in Figures 1 and 2, the receiving tray 14 is positioned above the pump mechanism 11 configured as described above and is attached to the upper end of the stem 10. The receiving tray 14 has a discharge hole 13 that communicates with the inside of the stem 10, and plays the role of receiving the contents discharged from inside the stem 10 and through the discharge hole 13 and accumulating them on its upper surface.

[0049] The receiving tray 14 comprises a fitting cylindrical portion 90 fitted to the upper end of the stem 10, and an annular receiving tray body 91 integrally formed to close the upper end opening 90a of the fitting cylindrical portion 90 and extending radially outward from the upper end of the fitting cylindrical portion 90, and is arranged coaxially with the container axis O (central axis of the stem 10).

[0050] The fitting cylinder portion 90 is formed in a cylindrical shape that surrounds the upper end of the stem 10 from the radial outside and is fitted to the stem 10. As a result, the entire receiving plate 14 is mounted on the upper end of the stem 10. Furthermore, the fitting cylinder portion 90 is formed to extend upward from the upper end of the stem 10 so that the receiving plate body 91 is positioned above the stem 10 at a distance from it.

[0051] The lower end of the fitting cylinder portion 90 is positioned inside the guide cylinder 22 of the mounting cap 12 before the receiving tray 14 is pressed down. The outer circumferential surface of the fitting cylinder portion 90 has elongated vertical ribs 92 that protrude radially outward and are close to or in contact with the inner circumferential surface of the guide cylinder 22. Multiple vertical ribs 92 are formed, for example, spaced apart in the circumferential direction. As a result, the fitting cylinder portion 90 is able to move up and down while being guided by the guide cylinder 22. Therefore, the entire receiving plate 14 is guided by the guide cylinder 22 to move up and down stably with minimal rattling.

[0052] The receiving tray body 91 is formed to gradually extend upward from the upper end of the fitting cylinder portion 90 radially outward. As a result, the entire receiving tray body 91 is formed in a dish shape that is slightly curved diagonally upward from the center to the outer edge. Therefore, the receiving tray body 91 is shaped to receive the contents discharged onto the upper surface of the receiving tray body 91 through the discharge hole 13 without spilling, and to stably accumulate the contents. Furthermore, the tray body 91 is formed such that its outer diameter is smaller than the inner diameter of the decorative cylinder 24 of the mounting cap 12. In addition, the upper surface of the tray body 91 is a smooth curved surface without any irregularities throughout.

[0053] As shown in Figures 2 and 3, the discharge hole 13 is formed in the receiving tray body 91 so as to penetrate the receiving tray body 91 vertically. Specifically, the discharge hole 13 is formed in an annular shape that extends continuously in the circumferential direction so as to surround the periphery of the opposing portion (inner member according to the present invention) 93 which is located inside the discharge hole 13.

[0054] The opposing portion 93 is positioned inside the discharge hole 13 such that at least a portion of it faces above the upper end opening 10c of the stem 10. In this embodiment, the opposing portion 93 is formed in a cylindrical shape smaller than the diameter D1 of the upper end opening 10c of the stem 10 and is positioned coaxially with the container axis O. Furthermore, the opposing portion 93 is formed in a vertically elongated shape extending along the container axis O, with its upper end positioned inside the discharge hole 13. As a result, the discharge hole 13 is positioned coaxially with the container axis O and is formed in an annular shape. Furthermore, the lower end of the opposing portion 93 extends beyond the space portion 95, which will be described later, and into the inside of the upper end of the stem 10. This makes it possible to discharge the contents from inside the stem 10 in a way that the contents are dispersed and flow around the opposing portion 93.

[0055] Furthermore, an annular enlarged diameter portion 93a is formed at the upper end of the opposing portion 93, projecting radially outward and positioned above the upper end opening 10c of the stem 10. In particular, the enlarged diameter portion 93a is formed so that its diameter is approximately the same as the diameter D1 of the upper end opening 10c of the stem 10. This makes it possible to change the direction of the flow of the contents by bringing at least a portion of the contents discharged upward from inside the stem 10 into contact with the enlarged diameter portion 93a from below. Furthermore, the discharge hole 13 is formed such that the flow path cross-sectional area around the entire circumference of the discharge hole 13 is larger than the flow path cross-sectional area at the upper end opening 10c of the stem 10.

[0056] The enlarged diameter portion 93a, including the upper end of the opposing portion 93, corresponds to the central part of the curved, dish-shaped receiving tray body 91 and is located inside the discharge hole 13. Furthermore, the enlarged diameter portion 93a is supported by the fitting cylinder portion 90 via a plurality of connecting ribs 94. These plurality of connecting ribs 94 are located in a space 95 formed between the receiving tray body 91 and the stem 10. The space 95 is formed between the receiving tray body 91 and the upper end opening 10c of the stem 10 and communicates the inside of the stem 10 and the inside of the discharge hole 13 with each other.

[0057] Multiple connecting ribs 94 are arranged within the space 95, protruding radially inward from the inner circumferential surface of the fitting cylinder portion 90, and are spaced apart in the circumferential direction. In the illustrated example, four connecting ribs 94 are formed at equal intervals in the circumferential direction. However, the number of connecting ribs 94 is not limited to this case.

[0058] The multiple connecting ribs 94 have a constant thickness in the circumferential direction and are formed as vertical ribs extending vertically within the space 95. Furthermore, the upper edges of the multiple connecting ribs 94 are integrally formed with respect to the lower surface of the enlarged diameter portion 93a. As a result, the entire opposing portion 93 is stably supported by the multiple connecting ribs 94 and is integrally assembled to the fitting cylindrical portion 90 via the connecting ribs 94.

[0059] Furthermore, the lower edges of the multiple connecting ribs 94 are in contact with the upper opening edge of the stem 10 from above. This allows the connecting ribs 94 to be brought into contact with the upper opening edge of the stem 10 when the fitting cylindrical portion 90 of the receiving plate 14 is attached to the upper end of the stem 10, thereby enabling the receiving plate 14 to be positioned relative to the stem 10.

[0060] As described above, since multiple connecting ribs 94 are arranged within the space 95, the flow path cross-sectional area of ​​the space 95 is defined by the diameter D2 of the portion of the space 95 excluding the connecting ribs 94 (i.e., the inner diameter of the fitting cylinder portion 90), as shown in Figure 2. In particular, the space 95 is formed such that the flow path cross-sectional area of ​​the space 95 is larger than the flow path cross-sectional area at the upper end opening 10c of the stem 10. Furthermore, the flow path cross-sectional area of ​​the upper end opening 10c of the stem 10 and the flow path cross-sectional area of ​​the space 95 are the cross-sectional areas excluding the cross-sectional area of ​​the opposing portion 93.

[0061] (overcap) As shown in Figure 1, the overcap 15 is formed in a top-cylindrical shape that covers the tray 14 from above and is detachably attached to the upper end of the decorative cylinder 24 of the mounting cap 12. In the illustrated example, the overcap 15 is attached to the upper end of the decorative cylinder 24 by an undercut fit. However, this is not the only way in which it can be attached; for example, the overcap 15 may be attached to the upper end of the decorative cylinder 24 by screw connection.

[0062] (Function of the dispensing device) Next, we will explain the case in which the contents are discharged using the discharger 1 configured as described above. In this case, as shown in Figure 4, the pump mechanism 11 can be activated by pushing down the receiving tray 14 as indicated by arrow F, against the upward biasing force of the stem 10 (elastic restoring force of the biasing member 80). Note that in Figure 4, a part of the pump mechanism 11 is shown as a side view.

[0063] Specifically, by pressing down on the receiving plate 14, the stem 10 can be pressed down together with the receiving plate 14. As a result, the enlarged diameter portion 10a of the stem 10 shown in Figure 1 moves downward and approaches the piston 60, and at the same time, the piston guide 50 moves downward together with the stem 10, so that the guide flange 52 moves away from the piston 60. As a result, the seal between the guide flange 52 and the inner piston cylinder 62 of the piston 60 is released, and the lower chamber 38 inside the cylinder 30 and the first through-hole 54 of the piston guide 50 are in communication through the second through-hole 55.

[0064] Furthermore, by further pressing down on the receiving tray 14, the enlarged diameter portion 10a of the stem 10 comes into contact with the piston 60, allowing the piston 60 to move downward together with the receiving tray 14. This pressurizes the lower chamber 38 within the cylinder 30, allowing the contents of the cylinder 30 to be supplied into the stem 10 through the first through hole 54 and the second through hole 55, and also allowing them to move upward within the stem 10 toward the receiving tray body 91.

[0065] As a result, as shown in Figure 5, the contents can be discharged from the upper end opening 10c of the stem 10 through the discharge hole 13, as indicated by the arrow in Figure 5, onto the upper surface of the receiving tray body 91. This allows the contents to be accumulated on the upper surface of the receiving tray body 91, for example, enabling a variety of uses for the contents.

[0066] After the contents are dispensed, when the pressure on the receiving tray 14 is released, the biasing member 80 shown in Figure 1 undergoes elastic restoration deformation, thereby applying an upward biasing force to the guide flange 52. This allows an upward biasing force to be applied to the receiving tray 14 via the guide flange 52 and the stem 10, restoring the receiving tray 14 and the stem 10 to their original positions by moving them upward.

[0067] Furthermore, in the above process, the guide flange 52 can be brought into contact with the piston 60 from below, thereby sealing the space between the guide flange 52 and the inner piston cylinder 62, and blocking communication between the lower chamber 38 in the cylinder 30 and the inside of the stem 10. Subsequently, the piston 60 can be moved upward together with the piston guide 50, thereby reducing the pressure in the lower chamber 38 within the cylinder 30. This causes the lower valve body 41 to separate from the inner circumferential surface of the tapered cylinder 32, opening the flow hole 35. As a result, the contents of the container body 2 can be drawn up into the cylinder 30 through the pipe 37, preparing for the next discharge.

[0068] As described above, according to the discharger 1 of this embodiment, by pressing down the receiving tray 14, the contents can be discharged through the stem 10 and the discharge hole 13 to the upper surface of the receiving tray body 91, for example, to be stored. In particular, in the discharger 1 of this embodiment, the discharge hole 13 formed in the receiving tray body 91 is formed in an annular shape that surrounds the periphery of the opposing portion 93 and extends continuously in the circumferential direction, unlike conventional designs, as shown in Figures 3 and 5. This allows the contents discharged from the upper end opening 10c of the stem 10 to be evenly distributed throughout the entire discharge hole 13, rather than being locally concentrated in a part of the discharge hole 13. Therefore, the force of the discharge of the contents can be suppressed, and the contents can be discharged evenly from the entire discharge hole 13 onto the upper surface of the receiving tray body 91 while suppressing the discharge speed.

[0069] This allows for the contents to be dispensed appropriately onto the top surface of the tray body 91 while suppressing unintended scattering of the contents, and also allows the contents to slowly accumulate on the top surface of the tray body 91. Furthermore, even if the tray 14 is pressed down without covering the dispensing hole 13 with an application tool such as cotton, the ejection of the contents can be suppressed, making it possible to dispense only the appropriate amount of contents while checking the amount dispensed.

[0070] Furthermore, when the receiving tray 14 is pressed down, as shown in Figure 5, a portion of the contents discharged upward from the upper end opening 10c of the stem 10 can be brought into contact with the enlarged diameter portion 93a from below, thereby changing the direction of the flow of the contents. Therefore, it is possible to prevent the entire contents discharged from the stem 10 from reaching the discharge hole 13 in a straight line. As a result, the force of the contents is weakened by contact with the enlarged diameter portion 93a, and then the contents can be discharged while being dispersed throughout the annular discharge hole 13. Therefore, the effects described above can be achieved even more effectively.

[0071] Furthermore, since the flow path cross-sectional area of ​​the discharge hole 13 is larger than the flow path cross-sectional area of ​​the upper end opening 10c of the stem 10, the discharge speed of the contents can be further suppressed when passing through the discharge hole 13. Specifically, the flow path cross-sectional area of ​​the upper end opening 10c of the stem 10 is 13.8 mm². 2 It is said that... In addition, the contents discharged from the upper end opening 10c of the stem 10 can be allowed to flow into the space 95 before being guided to the discharge hole 13. Moreover, since the flow path cross-sectional area of ​​the space 95 is larger than the flow path cross-sectional area of ​​the upper end opening 10c of the stem 10, the pressure of the contents can be reduced when they flow into the space 95, further suppressing the discharge speed.

[0072] Furthermore, since the upper surface of the receiving tray body 91 is a smooth curved surface without any irregularities throughout, it is easy to wipe the upper surface of the receiving tray body 91 with an application tool such as cotton. Therefore, it is easy to wipe away the dispensed contents, and it is easy to keep the upper surface of the receiving tray body 91 clean, resulting in a user-friendly dispenser 1.

[0074] For example, in the above embodiment, the diameter of the enlarged portion 93a was formed to be approximately the same as the diameter D1 of the upper end opening 10c of the stem 10, but the invention is not limited to this case. For example, the diameter of the enlarged portion 93a may be made larger than the diameter D1 of the upper end opening 10c of the stem 10, so that the entire contents discharged upward from inside the stem 10 come into contact with the enlarged portion 93a.

[0075] Furthermore, in the above embodiment, the opposing portion 93 may be formed separately from the receiving tray body 91 and then combined with the receiving tray body 91. Moreover, in the above embodiment, the case in which the opposing portion 93 and the discharge hole 13 are arranged coaxially with the container axis O which is common to the central axis of the stem 10 was described as an example, but the invention is not limited to this case.
