Contents ejection unit and ejection container

Abstract

This ejecting unit mixes two or more contents and ejects the same, wherein the two or more contents are prevented from contacting a valve, and as a result the reliability is increased.　Included are: a first valve for opening and closing a first flow inlet of a first channel through which a first content flows; and a second valve for opening and closing a second flow inlet of a second channel through which a second content flows. A third valve is disposed on the upper side of the second valve to prevent the first content, which is passed through the first channel and supplied to the first flow inlet, from contacting an upper surface of the second valve.

Description

[Technical field]

[0001] The present invention relates to a content ejection unit that mixes contents stored separately in a container when ejecting the contents. [Background technology]

[0002] Conventionally, there are known spray containers, such as spray containers for hair dye, that store multiple types of contents (dye, oxidizer, etc.) in respective storage bags and mix them at the tip of the nozzle of the stem when sprayed (Patent Documents 1 and 2). Even if multiple types of contents to be sprayed cause a chemical reaction when mixed, these spray containers can hold each of them in the spray container without causing a chemical reaction, and therefore can prevent deterioration in the spray container and clogging of the inside of the container by the reactants. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] U.S. Patent No. 8,505,775 [Patent Document 2] JP 2004-244109 A Summary of the Invention [Problem to be solved by the invention]

[0004] The spray containers disclosed in Patent Documents 1 and 2 use one or more valves that open when the stem is pressed down to open and close two flow paths that guide two types of contents from a storage bag to the tip of the nozzle of the stem, but when the contents are sprayed, there are locations where the two types of contents flowing through the two flow paths can reach the upper and lower surfaces of one valve, either directly or through gaps. Also, when filling two types of contents into a storage bag, a method is used in which the two types of contents are each supplied to the tip of the nozzle under pressure, causing the two types of flow paths to flow backwards, but even in this case, the two types of contents can reach the upper and lower surfaces of one valve, either directly or through gaps.

[0005] Generally, stem valves are made of elastic organic polymers such as rubber, and swell when they come into contact with the contents. When two types of contents reach the top and bottom of a valve, the difference in the properties of the two types of contents causes the amount of swelling at the top and bottom of the valve to differ, deforming the valve and causing it to move differently from what was intended at the time of design.

[0006] A valve that has been deformed due to swelling may not be able to open and close the two flow paths properly, which may result in two types of contents leaking out or one of the contents being unable to eject.

[0007] An object of the present invention is to prevent two or more contents from contacting a valve in a spray unit that mixes and sprays two or more contents, thereby improving reliability. [Means for solving the problem]

[0008] In order to achieve the above-mentioned object, the content ejection unit of the present invention has a first ejection tube that ejects a first content from its top end, a second ejection tube that ejects a second content from its top end, a first inlet provided on the side of the first ejection tube and allowing the first content to flow into the inside of the first ejection tube, a second inlet provided on the side of the second ejection tube and allowing the second content to flow into the inside of the second ejection tube, a first valve provided on the outer periphery of the first ejection tube and closing the first inlet in an openable and closable manner, a second valve provided on the outer periphery of the second ejection tube and closing the second inlet in an openable and closable manner, a first flow path that guides the first content to the first inlet, and a second flow path that guides the second content to the second inlet. The first jetting cylinder is arranged concentrically with the second jetting cylinder on the outer circumferential side of the upper part of the second jetting cylinder, and the first inlet and the first valve are located above the second inlet and the second valve in the axial direction of the second jetting cylinder. A third valve is arranged above the second valve to prevent the first content, which flows through the first flow path and is supplied to the first inlet, from contacting the upper surface of the second valve. Effect of the Invention

[0009] According to the present invention, by placing the third valve, it is possible to prevent the first contents from coming into contact with the upper surface of the second valve, so that only the second contents, and not the first contents, come into contact with the second valve, thereby preventing deformation due to swelling of the second valve and improving reliability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] A contents-ejecting unit according to an embodiment of the present invention will now be described.

[0012] First, referring to Figures 1(a) and 1(b) and Figures 2(a) and 2(b), a description will be given of a main configuration example and an operation example of the content-ejecting unit 10. Figures 1(a) and 1(b) are cross-sectional views of the ejection container 20 to which the content-ejecting unit 10 is attached when stationary and when ejecting, and Figures 2(a) and 2(b) are enlarged views thereof.

[0013] The ejection container 20 comprises two spaces (here, pouches 28, 29) for separately storing a first content A and a second content B, a container body 21 which houses the pouches 28, 29 and is filled with compressed gas, and a content ejection unit 10 attached to a mountain cup 22 provided on the upper part of the container body 21.

[0014] The content ejection unit 10 includes a stem 30, and when a user presses the tip of the stem 30, the content A contained in the pouch 28 of the container body 21 and the content B contained in the pouch 29 are ejected simultaneously. In the following description, the bottom side of the container body 21 is referred to as the lower side, and the side to which the mountain cup 22 is attached is referred to as the upper side in the up-down direction.

[0015] The content ejection unit 10 includes, as the stem 30, a first ejection tube 31 that ejects the first content A from a first ejection port 31a at the upper end, and a second ejection tube 32 that ejects the second content B from a second ejection port 32a at the upper end. The first ejection tube 31 is arranged on the outer periphery of the upper part of the second ejection tube 32 so that the central axis coincides with the second ejection tube 32 in a concentric manner. A first inflow port 33 that allows the first content A to flow into the first ejection tube 31 is provided on the side of the first ejection tube 31. A second inflow port 34 that allows the second content B to flow into the second ejection tube 32 is provided on the side of the second ejection tube 32. Here, as an example, the first inflow port 33 and the second inflow port 34 are provided at two locations in the circumferential direction of the first ejection tube 31 and the second ejection tube 32, respectively.

[0016] A first valve (first stem rubber) 40 that opens and closes the first inlet 33 is disposed on the outer periphery of the first ejection tube 31. A second valve (second stem rubber) 50 that opens and closes the second inlet 34 is disposed on the outer periphery of the second ejection tube 32.

[0017] The first inlet 33 and the first valve 40 are disposed above the second inlet 34 and the second valve 50 in the axial direction of the second jet cylinder 32 .

[0018] In addition, a housing 70 is arranged on the outside of the stem 30, the housing 70 having a first flow path 71 that guides the first content A to the first inlet 33 and a second flow path 72 that guides the second content B to the second inlet 34.

[0019] Here, in this embodiment, a third valve (hereinafter, referred to as a gate valve) 60 is disposed above the second valve 50. The gate valve 60 blocks the first contents A flowing through the first flow path 71 and supplied to the first inlet 33 from contacting the upper surface of the second valve 50. As a result, only the second contents B flowing through the second flow path 72 contacts the lower surface of the second valve 50, and the first contents A does not contact the upper surface, so that the upper surface of the second valve 50 can be prevented from swelling due to contact with the first contents A. Therefore, even if the second valve 50 is made of, for example, an elastic organic polymer and has the property of swelling due to contact with the contents, and the lower surface of the second valve 50 swells due to contact with the second contents B, the upper surface does not swell by a different amount depending on the first contents A. As a result, the shape and movement of the second valve 50 can be maintained as designed, and the second inlet 34 can be opened and closed with high reliability.

[0020] For example, the first flow path 71 can be configured by a housing 70 including a first cylindrical portion 71a arranged concentrically with the first ejection cylinder 31 outside the first ejection cylinder 31. The inner peripheral surface of the first cylindrical portion 71a supports the outer peripheral surface of the first valve 40. The first content A passes between the first cylindrical portion 71a and the outer peripheral surface of the first ejection cylinder 31 and reaches the first inlet 33.

[0021] On the other hand, the second flow path 72 can be configured to include a second cylindrical portion 72a at least a portion of which is disposed inside the housing 70 of the first flow path 71. The inner peripheral surface of the second cylindrical portion 72a supports the outer peripheral surface of the second valve 50. The second content B passes between the second cylindrical portion 72a and the outer peripheral surface of the second jetting cylinder 32 and reaches the second inlet 34.

[0022] In such a configuration, the gate valve 60 is disposed so as to block the gap between the upper end of the inner circumferential surface of the second cylindrical portion 72a and the outer circumferential surface of the second ejection tube 32. The gate valve 60 may have any shape as long as it can cover the upper surface of the second valve 50 and prevent the first internal portion A from coming into contact with the second valve 50. Specific examples of the shape of the gate valve 60 will be described in the following embodiment 1.

[0023] Moreover, it is preferable that a spacer (bush) 65 for maintaining the axial distance of the gate valve 60 from the first valve 40 be disposed between the first valve 40 and the gate valve 60 .

[0024] The first flow path 71 is connected to the first pouch by a pouch joint 81. The second flow path 72 is connected to the second pouch 29 by a pouch joint .

[0025] In this embodiment, the first ejection tube 31 and the second ejection tube 32 are integrated together to form the stem 30. A spring 79 is disposed at the bottom of the stem 30.

[0026] [Overview of operation] <Operation of each part during ejection> Here, the operation of the content-spouting unit 10 when spouting the contents A and B contained in the pouches 28 and 29 will be briefly described.

[0027] When the user is not pressing down on the stem 30 and no ejection operation is being performed (hereinafter referred to as the stationary state), the content ejection unit 10 is in a state in which the stem 30 is pushed up to the uppermost position by the spring 79, as shown in Figures 1(a) and 2(a).

[0028] The inside of the container body 21 is filled with compressed gas, and the pressure therein is higher than atmospheric pressure, and the pouches 28 and 29 are pressed. Since the first valve 40 closes the first inlet 33 and the second valve 50 closes the second inlet 34, the contents A in the pouch 28 and the contents B in the pouch 29 cannot flow into the inside of the stem 30 even though the pouches 28 and 29 are pressed, but the contents A reaches the upper end of the first flow path 71 of the housing 70 and is in contact with the upper surface of the gate valve 60 and the lower surface of the first valve 40. The contents B reaches the upper end of the second flow path 72 and is in contact with the lower surface of the second valve 50.

[0029] When the user presses the stem 30 from this stationary state, as shown in Fig. 1(b), the stem 30 moves (slides) axially downward while contacting the first valve 40, the second valve 50, and the gate valve 60 (arrow Y1, displacement h1). As the stem 30 descends, the first inlet 33 and the second inlet 34 move lower than the first valve 40 and the second valve 50, respectively, and the first inlet 33 and the second inlet 34 are simultaneously opened. As the first inlet 33 and the second inlet 34 are opened, the contents A and B flow into the stem 30 from the first inlet 33 and the second inlet 34, respectively.

[0030] The content A flows into the first ejection tube 31 from the first inlet 33, reaches the upper end of the first ejection tube 31, and is ejected from the first ejection port 31a. The content B flows into the second ejection tube 32 from the second inlet 34, reaches the upper end of the second ejection tube 32, and is ejected from the second ejection port 32a.

[0031] At this time, the valves that the contents A and B come into contact with when the stem 30 is pressed down are the same as those that come into contact with in the stationary state. That is, the content A comes into contact with the upper surface of the gate valve 60 and the lower surface of the first valve 40, and the content B comes into contact with the lower surface of the second valve 50.

[0032] When the user stops pressing the stem 30, the spring 79 pushes the stem 30 up (arrow Y2), and the first valve 40 returns to a resting state in which it closes the first inlet 33 and the second valve 50 closes the second inlet 34. Closure of the first inlet 33 and the second inlet 34 stops the ejection of the contents A and B.

[0033] <Operation when filling> As a method for filling the pouches 28, 29 in the ejection container 20 with the contents A and B, a method can be used in which, while the stem 30 is pressed down, the contents A and B are injected from the first and second ejection ports at the tip of the stem 30 toward the pouches 28, 29, respectively. That is, the contents A and B are injected from the ejection ports 31a, 32a of the ejection tubes 31, 32, and flow through the contents ejection unit 1 in the opposite direction to the direction of ejection, thereby injecting the contents A and B into the pouches 28, 29, respectively. The flow of the contents A and B in this case will be described below.

[0034] When the stem 30 is pressed down, the first valve 40 opens the first inlet 33, and the second valve 50 opens the second inlet 34. The first inlet 33 is located lower than the first valve 40, and the second inlet 34 is located lower than the second valve 50.

[0035] In this state, the contents A and B are injected from the ejection ports 31a and 32a of the ejection tubes 31 and 32 at a pressure higher than the pressure of the gas filled in the container body 21.

[0036] The content A injected from the first ejection port 31a passes through the ejection tube 31 toward the first inlet 33 and exits from the first inlet 33 to the first flow path 71 outside the stem 30. The content A exiting the first flow path 71 advances downward through the first flow path 71 and is contained in the pouch 28.

[0037] Part of the contents A passing through the first flow path 71 touches the bottom surface of the first valve 40 and the top surface of the gate valve 60. Because the contents A are injected at high pressure, the gate valve 60 is pressed against the stem 30 by the contents A, and the gate valve 60 can seal the contents A so that it does not come into contact with the second valve 50. Therefore, the contents A do not reach the bottom surface of the gate valve 60 or the second valve 50.

[0038] On the other hand, the contents B injected from the second outlet 32a passes through the inside of the ejection tube 32 and comes out from the second inlet 34 to the second flow path 72 outside the stem 30. The contents B that comes out to the second flow path 72 proceeds further downward and is contained in the pouch 29. A part of the contents B that comes out to the second flow path 72 comes into contact with the lower surface of the second valve 50. Although the contents B are injected at high pressure, since the second valve 50 is in contact with the outer periphery of the stem 30, the contents B do not reach the gate valve 60 or the first flow path 71 located above the second valve 50.

[0039] As described above, in the content ejection unit 10, the gate valve 60 prevents the first content A from contacting the second valve 50, whether the stem is pressed or not pressed by the user. That is, in the content ejection unit 10, only the first content A contacts the first valve 40, and only the second content B contacts the second valve 50. This prevents deformation of the valve caused by the difference in the amount of swelling of the upper and lower surfaces of the valve due to multiple types of contents coming into contact with one valve, and prevents deviation in the ejection timing of multiple types of contents.

[0040] The specific configuration and operation of the content ejection unit will be described below with reference to embodiments 1 to 5. The configuration and operation of the content ejection unit 10 described above are common to the content ejection units of the following embodiments, and the following will describe the points omitted in the above configuration and operation.

[0041] (Contents ejection unit 10A of embodiment 1) The content-ejection unit 10A of the first embodiment will be described in detail. As shown in Fig. 3, the content-ejection unit 10A of the first embodiment uses a gate valve 60 having an inclined tubular portion 61 and an annular portion 62 connected to the lower end of the tubular portion 61. The tubular portion 61 is inclined so that the diameter at the upper end is smaller than the diameter at the lower end, and the inner diameter at the upper end is designed to contact the outer surface of the stem 30. In addition, the outer diameter of the annular portion 62 is designed to contact the inner surface of the upper portion of the tubular portion (fixed tubular portion 73) that constitutes the second flow path 72.

[0042] In this embodiment, the gate valve 60 is disposed so that the lower surface of the annular portion 62 is in contact with the upper surface of the second valve 50 .

[0043] In this way, by using a gate valve 60 having a tubular portion 61 with an inclined side, when the first contents A are sprayed or filled, the first contents A flows through the flow path above the gate valve 60, and when the first contents A reaches the upper surface of the gate valve 60, a pressing force is applied from the first contents A to the gate valve 60 in all directions, as shown in Fig. 4. This pressing force presses the inner peripheral end face (upper end) of the gate valve 60 against the stem 30, and the outer peripheral end face is pressed against the fixed tubular portion 73. This allows the gate valve 60 to effectively seal the second valve 50, and is highly effective in blocking the first contents A from reaching the second valve 50.

[0044] As shown in Figures 1(a) and 2(a), a spacer (bush) 65 is positioned between the underside of the first valve 40 and the gate valve 60, sandwiched between them and pressing the gate valve 60 against the upper surface of the second valve 50.

[0045] 1(a) and 2(a), the bush 65 has a cylindrical portion 65a disposed in a position surrounding the stem 30, and a rib 65b provided on the inside of the upper part of the cylindrical portion 65a. The cylindrical portion 65a is sandwiched between the lower surface of the first valve 40 and the gate valve 60, that is, the upper end of the cylindrical portion 65a contacts the lower surface of the first valve 40, and the lower end contacts the upper surface of the annular portion 62 on the outer periphery of the gate valve 60. As a result, the lower end of the cylindrical portion 65a of the bush 65 presses down the annular portion 62 of the gate valve 60, pressing the gate valve 60 against the upper surface of the second valve 50.

[0046] The rib 65b is provided on the inner side of the cylindrical portion 65a, and functions as a positioning member that suppresses radial positional deviation of the cylindrical portion 65a with respect to the central axis of the stem 30 by contacting the outer periphery of the stem 30. That is, the central axis of the cylindrical portion 65a is always located within a predetermined range from the central axis of the stem 30 by contacting the outer periphery of the stem 30. The shape of the cylindrical portion 65a of the bush 65 is not limited to a cylinder, and may be any shape as long as the upper end contacts the lower surface of the first valve 40 and the lower end contacts the upper surface of the gate valve 60, respectively, and applies a force to press down the gate valve 60. For example, one or more slits may be provided in the cylindrical portion 65a. The ribs 65b may be arranged at predetermined intervals in the circumferential direction, and may be cylindrical.

[0047] Here, the shape of the housing 70 will be described. The housing 70 is a cylindrical body that covers the outer periphery of the first valve 40, the bush 65, the gate valve 60, and the second valve 50. The first valve 40 is disposed at the upper end of the housing 70, and the first valve 40 closes the opening at the upper end of the housing 70 to prevent the contents from flowing out from the opening.

[0048] The housing 70 has, at its lower portion, two bifurcated tubular portions 71 and 72. A pouch joint 81 is attached to one tubular portion 71a, and a pouch joint 82 is attached to the other tubular portion 72a.

[0049] 1(a) and 2(a), the fixed cylindrical portion 73 described above for fixing the outer periphery of the second valve 50 and the gate valve 60 is disposed at the upper portion of the cylindrical portion 72a of the second flow path 72. The fixed cylindrical portion 73 has a height such that its upper end is at a position equal to or higher than the upper end of the annular portion 62 of the gate valve 60.

[0050] In addition, it is preferable that the upper end of the first ejection tube 31 of the stem 30 is at a different height from the upper end of the second ejection tube 32. This makes it possible to prevent the contents A and B from being mixed and injected when filling the contents A and B, respectively. In the content ejection unit 10A shown in Figures 1(a) and 2(a), the height of the upper end of the first ejection tube 31 is lower than the height of the upper end of the second ejection tube 32.

[0051] Grooves 33c, 34c are provided on the outer peripheral surface of the stem 30 along the circumferential direction at the position of the first inlet 33 and the position of the second inlet 34, respectively. The upper side surfaces of the grooves 33c and 34c are inclined surfaces 33b, 34b, respectively, in which the diameter of the stem 30 decreases from the top to the bottom. As a result, the first valve 40 and the second valve 50 at the positions of the grooves 33c, 34c are pushed outward by the inclined surfaces 33b, 34b as the stem 30 is pressed down, and move out of the positions of the grooves 33c, 34c, respectively, thereby opening the first inlet 33 and the second inlet 34.

[0052] As shown in Figures 1(a) and (b) and Figures 2(a) and (b), the upper end of the fixed cylindrical portion 73 of the housing 70 is located at a height equal to or higher than the upper end of the annular portion 62 of the check valve 60, and the outer periphery of the second valve 50 is covered by the fixed cylindrical portion 73.

[0053] As described above, in the content ejection unit 10A of embodiment 1, the gate valve 60 has a cylindrical portion 61 with an inclined shape, so that it is possible to exhibit high sealing properties that prevent the first content A from reaching the second valve.

[0054] It should be noted that this embodiment may also be configured without the bush 65 that holds down the gate valve 60. For example, as shown in Fig. 5, a recess 73b may be provided on the inner wall surface of the fixed cylindrical portion 73, and the outer periphery of the annular portion 62 of the gate valve 60 may be inserted into the recess 73b to fix the gate valve 60 to the inner wall of the fixed cylindrical portion 73. As a result, even in a configuration without the bush 65, the gate valve 60 can be fixed onto the second valve 50, and the gate valve 60 can seal the second valve 50.

[0055] <Overall configuration of the ejection container 20>

[0056] Here, the overall configuration of the ejection container 20 equipped with the content ejection unit 10 will be described in more detail.

[0057] The container body 21 and the mountain cup 22 are rotating bodies centered on the axis of the stem 30, and the upper end of the stem 30 protrudes from a hole provided in the upper center of the mountain cup 22 to a height that allows it to be pressed down by a user.

[0058] Although not shown, the ejection container 20 may be fitted with a cap that covers at least a portion of the upper part of the content ejection unit 10, and this cap may be detachable from the ejection container 20.

[0059] Each part constituting the ejection container 20 can be made of any material selected from materials commonly used for containers such as plastic, rubber, metal, ceramics, etc., depending on the application, as long as the material is not corroded by the contents.

[0060] (Contents ejection unit 10B of embodiment 2) The configuration of the content-ejecting unit 10B of the embodiment 2 will be described with respect to the differences from the configuration of the content-ejecting unit 10A of the embodiment 1. As shown in Figures 6(a) and (b), the content-ejecting unit 10B differs from the embodiment 1 in that the shape of the tubular portion 61B of the gate valve 60 is an outwardly convex curved shape.

[0061] The operation of content-ejecting unit 10B is the same as that of content-ejecting unit 10A of embodiment 1, however, in content-ejecting unit 10B, tubular portion 61B has an outwardly convex curved shape, so that it is less likely to be crushed by the pressure of content A and can withstand higher pressure filling, etc.

[0062] (Contents ejection unit 10C of embodiment 3) The configuration of the content-spouting unit 10C of the embodiment 3 will be described. The content-spouting unit 10C differs from the embodiment 1 in that the shape of the tubular portion 61C of the gate valve 60 is a curved shape that is convex inward, as shown in Figures 7(a) and (b).

[0063] The operation of content-ejecting unit 10C is the same as that of content-ejecting unit 10A of embodiment 1, but in content-ejecting unit 10C, tubular portion 61C has an inwardly convex curved shape, so that when content A is filled, it deforms with less pressure than in embodiment 1 and is pressed against stem 30, thereby sealing the upper surface of second valve 50.

[0064] (Contents ejection unit 10D of embodiment 4) A content-spouting unit 10D of embodiment 4 will be described below. As shown in Figures 8(a) and (b), the content-spouting unit 10D is different from the above-mentioned content-spouting units 10A to 10C in that the gate valve 60 is annular and does not have a cylindrical portion.

[0065] At least the upper end of the inner circumference of the annular gate valve 60 is in contact with the outer circumferential surface of the stem 30, and the outer circumferential portion is fixed to the housing 70 in the same manner as the annular portion 62 in the first embodiment. In this way, the gate valve 60 seals the contents A so that they do not reach the upper surface of the second valve 50.

[0066] (Contents ejection unit 10E of embodiment 5) A content-ejecting unit 10E of embodiment 4 will be described. The content-ejecting unit 10E is different from the above-mentioned content-ejecting units 10A to 10D in that the gate valve 60 is disposed at a position spaced apart from the second valve 50 on the axially upward side, as shown in Fig. 9(a) and (b).

[0067] The shape of the gate valve 60 of the content-ejecting unit 10E may be any of the gate valves 60 of the content-ejecting units 10A to 10D described above.

[0068] In order to fix the gate valve 60, a recess 73b is provided in the fixed cylinder portion 73, and the outer periphery of the gate valve 60 is inserted into the recess 73b. As shown in FIG. 9(b), the recess 73b is provided at a position higher than the upper surface of the second valve 50.

[0069] The lower end of the bush 65 presses downward against the annular portion 62D of the gate valve 60. This results in a configuration in which the inner peripheral portion of the gate valve 60 does not rise above the outer peripheral portion fixed to the recess 73b.

[0070] The operation of the contents-ejecting unit 10E is the same as that of the contents-ejecting unit 10A of the first embodiment.

[0071] In the contents ejection units of the first to fifth embodiments, the stem 30 is configured to be slidable while in contact with the gate valve 60, but the configuration is not limited to the above as long as no gap is generated between the outer periphery of the gate valve 60 and the inside of the housing 70, and between the inner periphery of the gate valve 60 and the outer periphery of the stem 30. For example, the gate valve 60 may be configured such that when the stem 30 is pressed down by the user, the portion in contact with the stem 30 descends and bends together with the stem 30.

[0072] Furthermore, the tubular portion 61 of the gate valve 60 is not limited to an inclined or curved shape, and may have a shape that follows the outer peripheral surface of the stem 30. In this case, when the stem 30 is pressed by a user, it descends while contacting the inner peripheral surface of the tubular portion 61, and when it returns to its original position, it ascends while contacting the inner peripheral surface of the tubular portion 61.

[0073] The stem 30 and the housing 70 may be made of resins such as polypropylene, high-density polyethylene, polyacetal, and polybutylene terephthalate. The first valve 40, the second valve 50, and the gate valve 60 may be made of the same material or different materials. These materials may be made of resins such as polyethylene, rubber members, and elastic bodies such as polypropylene, high-density polyethylene, polyacetal, and polybutylene terephthalate. The spring 79 may be made of any member having elasticity, such as a resin spring, a metal spring, or a coil spring.

[0074] Since the gate valve 60 in the above-mentioned embodiments 1 to 4 is partially in contact with the second valve 50, it is possible to manufacture the gate valve 60 and the second valve 50 by making them continuous at the contacting portion and molding them as a single unit.

[0075] In the content-spouting units of the first to fifth embodiments described above, the gate valve 60 and the bush 65 are configured as separate members, but the gate valve 60 and the bush 65 may be formed integrally. [Explanation of symbols]
