[Problems to be solved by the invention]

In the ejector disclosed in Patent Document 1, a specific amount of content is ejected by pressing the piston once. However, when it is desired to eject less than the specified amount of content, it is necessary to manually adjust the degree of depression to stop the piston in the middle of the depression step. Since it is not easy to perform such manual adjustment accurately, it is difficult to accurately perform a small amount of ejection in the conventional ejector.

In view of the foregoing, an object of one aspect of the present invention is to provide an ejector that can accurately eject a desired amount even in a case of a small amount of ejection.
[Technical means to solve the problem]

In order to solve the above-mentioned problems, an ejector according to an aspect of the present invention includes a storage body that stores contents, a pump portion that ejects the contents and has a plurality of pistons, and a pressing body that can abut the pistons. And pressing the piston; the pressing body can move relative to the pump portion along a plane orthogonal to the axial direction of the piston, and the number of the abutting pistons can be changed by the moving of the pressing body.
[Effect of the invention]

According to one aspect of the present invention, an ejector capable of accurately ejecting a desired amount even in a case of a small amount of ejection is provided.

Hereinafter, the embodiment for implementing the present invention will be described with reference to the drawings, but the present invention is not limited to the embodiment described in this specification. In the following description, the x direction, the y direction, and the z direction are mutually perpendicular directions, the x direction and the y direction are horizontal directions, and the z direction is a vertical direction. In this specification, the lower side means the lower side in the vertical direction, and the upper side means the upper side in the vertical direction.

A perspective view of this embodiment is shown in FIG. 1. FIG. 1 shows, as an example, an ejection device 100 including two ejectors 10A and 10B. An exploded view of the ejection device 100 of FIG. 1 is shown in FIG. 2. 3 (a) is a cross-sectional view taken along the line I-I (I-I arrow view) of the ejection device 100 of FIG. 1, and FIG. 3 (b) is a plan view.

The ejectors 10A and 10B are configured to eject the contents contained in the ejector to the outside by a pump. The content is not limited as long as it exhibits fluidity at least at the time of ejection and can be extruded from the ejection outlet, and may be a fluid (liquid), fluid, powder, or the like. The content may be a dispersion such as a solution, an emulsion, a suspension, or the like, or may be in a state called a gel, a slurry, a paste, a cream, or the like. When the contents are liquid (liquid), it can be a state with a viscosity close to water, or a creamy state. For example, the viscosity of the content at 30 ° C is preferably 3000 to 150,000 mPa ･ s, and more preferably 5,000 to 30,000 mPa ･ s. The content system contains, for example, oily ingredients, water-based ingredients, surfactants, film agents, powders, pigments, and medicaments, and can be applied to lotions, lotions, sunscreens, foundations, foundations, concealers, eye shadows, lips Products, hair care products, fragrance products, etc. In addition, the contents also include a person who mixes with a gas such as air to form a bubble shape (foam shape) and ejects, or a person who holds the bubble shape.

Hereinafter, the configuration and function of each ejector will be described first. In the form shown in the figure, the ejectors 10A and 10B are symmetrical in structure (the planes are symmetrical about the plane along the y direction), and the basic structure and function are the same. Therefore, the ejector 10A will be described as a representative. In addition, as described later, although components common to the ejectors 10A and 10B (components common to the ejectors 10A and 10B) exist, for such common components, the A or B symbol is not marked after the reference number.

As shown in FIG. 1 to FIG. 3, the ejector 10A includes: a storage body 50A that stores contents; a pump portion 20A that discharges the contents stored in the storage body 50A to the outside; and a pressing portion 30A that Used to press a movable element (piston) in the pump portion 20A.

As shown in FIG. 2, the pump section 20A includes a plurality of pistons 22Aa, 22Ab, and 22Ac (in the case of 22A in combination). Furthermore, the pump section 20A includes a pump section body 21, and a plurality of cylinders (through-holes) 23Aa, 23Ab, and 23Ac corresponding to the number of pistons 22A are formed in the pump section body 21. In the form shown in the figure, the number of the pistons 22A (that is, the number of the cylinders 23A) is three, but the number of the pistons 22A may be plural, and the number is not limited to three. One end of each of the pistons 22A (the end on the storage body 50A side or the content LA side) is inserted into each of the plurality of cylinders 23A, and can slide liquid-tightly relative to each of the cylinders 23A.

A frame body 40 is disposed below the pump section body 21. The frame body 40 is liquid-tightly coupled to the pump section body 21 by fitting or the like. As shown in FIG. 2 and FIG. 3 (a), since a recess is formed on the upper portion of the frame 40, a space is formed by combining the frame 40 and the pump portion main body 21, whereby the content LA can be formed to pass therethrough. Runner 27A. The flow path 27A communicates with a discharge port (nozzle) 24A formed on the side of the pump section body 21.

In addition, as shown in FIG. 2 and FIG. 3 (a), when a plurality of ejectors 10A and 10B are arranged in the x direction, and the pump main body 21 and the frame 40 are used as components common to the ejectors 10A and 10B At this time, the flow passage 27A is not connected to the flow passage 27B of the adjacent ejector 10B. Specifically, a concave portion 43A for the ejector 10A and a concave portion 43B for the ejector 10B are individually formed on the upper portion of the common frame 40. If it is replaced with another expression, it can be said that the runner 27A and the runner 27B are spaced apart by the partition plate 44.

The frame 40 has a function of covering the storage body 50A and protecting the storage body 50A. The storage body 50A can be attached to the upper part of the housing 40 from the lower side (from the inside of the housing 40). In the form shown in the figure, a thread is engraved on the side surface of the opening portion 51A of the storage body 50A, and a thread that is screwed onto the side surface of the opening portion of the storage body 50A is also formed on the lower surface of the upper portion of the frame 40. However, the storage body 50A may be attached to the frame body 40 by other forms such as fitting.

The storage body 50A is preferably detachably attached to the frame body 40. Thereby, when the storage body 50A becomes empty or the content in the storage body 50A becomes small, the storage body can be replaced with a new storage body filled with the contents. In addition, the pump section 20A and the pressing section 30A can be continuously used. In addition, when the storage body 50A becomes empty or the contents in the storage body 50A become small, the storage body 50A may be temporarily removed from the housing 40 and filled with the contents, and mounted on the housing 40 again.

As shown in FIG. 3, a suction port 41A is formed on the upper portion of the housing 40 and communicates with the interior of the mounted housing 50A. A suction pipe 42A extending to the storage body 50A is communicated with the suction port 41A. When the pump unit 30A operates, the content LA is sucked up from the end of the suction pipe 42A, and flows into the flow passage 27A through the suction port 41A.

The storage body 50A may be configured as a so-called vacuum container. For example, the storage body 50A may be constituted by an outer container and a flexible inner bag that is detachably mounted inside the outer container, and the contents may be stored in the inner bag. In addition, it can be configured as follows: by the action of the pump portion, the contents are sucked from the suction port while the inner bag is reduced in volume and deformed, and air is sent to the inner bag and the outside through the air inflow hole formed in the outer container. Between containers. Alternatively, the inner plate can be configured to slide up and down inside the storage body, and the upper part is set as the storage portion of the contents, and the inner plate is raised by the role of the pump. The contents are ejected while the storage portion is reduced in volume. The structure of such a vacuum container is more suitable for containing contents that are liable to cause deterioration or change in properties due to contact with air.

The pressing portion 30A includes a pressing body 32A capable of pressing down a plurality of pistons 22A. In the illustrated form, the pressing body 32A has a cup-like shape (FIG. 2), and a pressing rib 32Aa (FIG. 3 (a)) protruding downward is formed on the inner side (lower side) of the pressing body 32A. The pressing rib portion 32Aa may abut the upper end surface (the end surface on the side opposite to the flow path 27A or the side without the content LA) of the plurality of pistons 22A. When the pressing rib 32Aa is depressed, the piston 22A that the pressing rib 32Aa abuts is depressed. FIG. 3 (a) shows a case where the pressing rib 32Aa abuts at least the upper end surface of the piston 22Aa.

FIG. 4 shows a view of the pressing body 32A as viewed from the lower side (the side on which the piston 22A is disposed). The pressing rib portion 32Aa protruding from the lower side (inside) of the pressing body 32A has a continuous band shape that is curved along the outer edge of the pressing body 32A in a plan view. However, as long as the number of the abutting pistons 22A can be changed by moving (rotating), the planar shape of the pressing rib 32Aa may not follow the contour of the outer edge of the pressing body 32A, or may be discontinuous. In addition, the pressing body 32A includes a cylindrical protrusion 32Ac (see FIGS. 3 (a) and 4) that protrudes downward from the center in a plan view. The cylindrical protrusion 32Ac is configured to be engaged with a protrusion 34Aa of a support body 34 described later. In the form shown, the pressing rib 32Aa is combined with the cylindrical protrusion 32Ac, that is, although it extends from the cylindrical protrusion 32Ac, the two may not be combined. However, according to the illustrated form in which the pressing rib 32Aa is combined with the cylindrical protrusion 32Ac, it is preferable because the strength can be increased.

A knob 32Ab is provided on the upper side of the pressing body 32A (the side opposite to the pressing rib 32Aa), and the user can hold the knob 32Ab to rotate the pressing portion 30A. As described in detail later, the number of pistons 22A that the pressing ribs 32Ab abut can be changed by this rotation.

As shown in FIGS. 1 to 3, the pressing body 32A may be covered by the lid body 31. In the form shown in the figure, since the knob 32Ab that can be operated by the user is pushed upward by the pressing body 32A, the cover 31 is provided so as not to interfere with the protruding portion and the movable range of the knob 32Ab. Therefore, the cover body 31 may be formed in a shape in which an opening corresponding to at least the protruding portion of the knob 32Ab and the movable range is formed on the upper surface (FIG. 2 and FIG. 3 (b)).

The pressing body 32A is supported by the support body 34. In addition, the support body 34 and the pressing body 32A are configured to be movable in the vertical direction together. The support body 34 can be pressed down to the vicinity of the pump portion body 21 provided on the lower side thereof, and the pressing body 32A is pressed down together with the support body 34 in accordance with this action. When the support body 34 is pushed up, the pressing body 32A is also pushed up with this operation.

In the form shown in the figure, a protrusion 34Aa protruding upward is provided at the center of the support body 34 and engages with a cylindrical protrusion 32Ac provided on the inner side (lower side) of the pressing body 32A. That is, the protrusion 34Aa of the support body 34 is inserted into the cylindrical protrusion 32Ac of the pressing body 32A. Since the cylindrical protrusion 32Ac is rotatable relative to the protrusion 34Aa of the support body 34, the protrusion 34Aa of the support body 34 can be centered (with the center axis of the protrusion 34Aa as the center), and the pressing body 32A can be rotated.

A spring 35 is provided below the support body 34. When the support body 34 is pressed by the user to apply pressure, the spring 35 is compressed and energized. In addition, when the user pressurizes the support body 34, the support body 34 can be pushed upward by the restoring force of the spring 35, and returned to the original position.

In addition, a guide protrusion 34b may be provided below the support body 34. The guide protrusion 34b is inserted into a hole 21a formed on the upper side of the pump section body 21 and is slidable in the hole 21a. The spring 35 may be disposed in the hole 21 a, and the guide protrusion 34 b of the support body 34 may be inserted into the spring 35. In this way, the guide protrusion 34b of the support body 34 can be inserted into the hole 21a of the pump body 21 and can be slid, so that the support body 34 can be stably moved in the vertical direction (z direction), and the spring 35 can be stabilized. Compression deformation.

As shown in FIG. 3 (a), holes are formed in the support body 34 corresponding to the plurality of pistons 22A, respectively. The upper portion of the piston 22A protrudes upward from the support 34 through each hole. Here, the diameter of the upper portion of the piston 22A is larger than the diameter of the central portion and larger than the diameter of the hole of the support 34. Therefore, as described above, when the support body 34 is pushed upward and returned to the original position, the upper portion of the piston 22A abuts against the portion of the support body 34 surrounding the hole, and is lifted upward together with the support body 34.

FIG. 5 schematically shows the flow of the contents LA caused by the operation (pump action) of the pump section 20A. Fig. 5 is a partial view showing the cross section taken along the line II-II in Fig. 1 obliquely. The II-II line section is a section through one of the plurality of pistons 22A (piston 22Ac) and the ejection port 24A.

As described above, since the recessed portion 43A is provided on the upper portion of the frame body 40 and the frame body 40 and the pump portion body 21 are tightly coupled, a sealed space is formed between the frame body 40 and the pump portion body 21 and a self-contained body 50A A flow path 27A communicating with the discharge port 24A. That is, the contents LA can flow from the inside of the storage body 50A to the discharge outlet 24A through the suction port 41A formed in the upper portion of the housing 40.

A suction valve 26A is arranged on the storage body 50A side of the flow path 27A (FIGS. 3 (a) and 5). The suction valve 26A prevents the contents temporarily flowing into the flow path 27A from being returned to the storage body 50A. In the form shown, the suction valve 26A is a ball valve, but the form of the valve is not limited to that shown in the figure. The suction valve 26A can be slightly pressed by a spring or the like to avoid being affected by some pressure fluctuations in the flow path 27A and being opened at an unexpected timing.

On the other hand, a discharge valve 25A is arranged on the discharge port 24A side of the flow path 27A. In the form shown, the discharge valve 25A includes a valve body 25Aa, a fixing portion 25Ab for preventing the discharge valve 25A from falling off the pump body 21, and a connection portion 25Ac, which connects the valve body 25Aa and the fixing portion 25Ab. Since the connecting portion 25Ab is flexible, the valve body 25Aa can move in the vertical direction (z direction) due to a change in pressure received from the content.

The piston 22Ac is slid into the cylinder block 23Ac in a liquid-tight manner. Further, the pressing rib portion 32Aa of the pressing body 32A is in contact with the end surface above the piston 22Ac. Therefore, when the user presses the pressing portion 30A with the pressing rib 32Aa of the pressing body 32A downward, the piston 22Ac is depressed. Thereby, the contents filled in the cylinder body 23Ac are squeezed out, and the pressure in the flow passage 27A is increased. Thereby, the valve body 25Aa of the discharge valve 25A moves upward and opens. In addition, when the discharge valve 25A is opened, the contents LA can be discharged to the outside through the discharge port 24A. At this time, as the pressure in the flow passage 27A rises, the suction valve 26A provided on the upper portion of the housing 40 is pressed toward the storage body 50A side, so the suction valve 26A is maintained closed. Therefore, the content LA can be prevented from flowing backward from the flow path 27A into the storage body 50A.

After the content LA is ejected, if the force applied to the pressing portion 30A by the user is released, the support 34 is pushed up by the restoring force of the energized spring 35 (FIG. 2 and FIG. 3 (a)) to return to The original position. As described above, the diameter of the upper portion of the piston 22Ac is larger than that of the central portion. Therefore, as the support body 34 is pushed up, the piston 22Ac also moves upward and rises to the upper side. This reduces the pressure in the cylinder 23Ac (the pressure in the flow path 27A). As a result of this pressure reduction, the suction valve 26A is opened, and the content LA stored in the storage body 50A is sucked into the flow path 27A through the suction pipe 42A and the suction port 41A. On the other hand, since the 27A in the flow path is maintained in a closed state by the lifting and depressurization of the piston 22Ac, the ejection of the content LA does not occur.

The pump format of the pump unit 20A in the ejector 10A is not limited to those shown in the drawings. The shape of the flow path and the arrangement of the valves can also be changed as appropriate. Moreover, the pressing operation of the piston may be performed electrically.

Next, the relationship between the rotation of the pressing body and the number of pistons that the pressing body abuts and presses will be described with reference to FIGS. 6 to 9. 6 to 9 are partial views of the ejector 10B. In any of FIG. 6 to FIG. 9, a partial plan view of the pressing portion 30B after the cover 31 is removed is shown as (a), and a sectional view taken along the line III-III of (a) obliquely is shown as (b). ). In FIGS. 6 to 9, the arrangement of the pressing rib 32Ba is changed by rotating the pressing body 32B.

In FIG. 6 (a), in a plan view, the pressing ribs 32Ba overlap the upper end surfaces of the three pistons 22Ba, 22Bb, and 22Bc. That is, as shown in FIG. 6 (b), the pressing rib 32Ba abuts the upper end surfaces of the three pistons 22Ba, 22Bb, and 22Bc. Therefore, when the pressing portion 30B is depressed, that is, when the pressing rib 32Ba is depressed, all of the three pistons 22Ba, 22Bb, and 22Bc are depressed by the pressing rib 32Ba. Thereby, all the pumps of the three pistons 22Ba, 22Bb, and 22Bc can be operated.

FIG. 7 shows a state after the pressing body 32B is rotated clockwise by 60 ° from the state shown in FIG. 6. As shown in FIG. 7 (a), the pressing rib 32Ba overlaps the upper end surfaces of the pistons 22Bb and 22Bc in a plan view. That is, as shown in FIG. 7 (b), the pressing rib 32Ba is in contact with the upper end surfaces of the two pistons 22Bb and 22Bc. Therefore, when the pressing portion 30B (pressing the rib portion 32Ba) is depressed, the two pistons 22Bb and 22Bc are depressed, but the piston 22Ba is not depressed.

In the configuration of the pressing body 32B shown in FIG. 7, the number of actuated pistons is less than the state shown in FIG. 6. Therefore, in the same pressing step of pressing the rib 32Ba, a smaller amount of contents can be ejected. More specifically, if the amount of the content extruded from each of the pistons 22Ba, 22Bb, and 22Bc of this form is the same, the configuration of the pressing body 32B of FIG. 7 is the same as that of the pressing body 32B of FIG. 6. Compared with the situation, the ejection amount of the contents becomes two thirds.

FIG. 8 shows a state after the pressing body 32B is further rotated clockwise by 60 ° from the state shown in FIG. 7. As shown in FIG. 8 (a), the pressing rib 32Ba coincides with the upper end surface of the piston 22Bc in a plan view, but does not coincide with the upper end surfaces of the pistons 22Ba and 22Bb. That is, as shown in FIG. 8 (b), the pressing rib 32Ba abuts only on the upper end surface of one piston 22Bc. Therefore, when the pressing portion 30B (the pressing rib portion 32Ba) is depressed, the piston 22Bc is depressed, and the other pistons 22Ba and 22Bb are not depressed.

In the configuration of the pressing body 32B shown in FIG. 8, the number of actuated pistons is less than the state shown in FIGS. 6 and 7. If the amount of the contents extruded from each piston is the same, in the configuration of the pressing body 32B of FIG. 8, compared with the configuration of the pressing body 32B of FIG. 6, the same pressing force of the pressing rib 32B can be reduced. The ejection amount of the content extruded in the step is set to one third.

FIG. 9 shows a state after the pressing body 32B is further rotated clockwise by 60 ° from the state shown in FIG. 8. As shown in FIG. 9 (a), the pressing rib 32Ba does not overlap with the upper end surface of any piston 22B in a plan view. That is, as shown in FIG. 8 (b), the pressing rib 32Ba does not contact the upper end portion of any of the pistons 22B. Therefore, even if the pressing portion 30B (pressing portion 32B) is depressed, the piston 22B is not depressed, and the ejection of the contents does not occur.

As described above, in this embodiment, the number of the pistons 22B abutted by the pressing body 32B can be changed by relatively rotating the pressing body 32B relative to the piston 22B (the pump portion 20B). Therefore, the ejection amount can be changed in the same reduction step. In the past, when a small amount of the ejection amount to be ejected in the pressing step of less than one time was to be ejected, it was necessary to manually adjust the pressing degree of the piston to perform the ejection operation. This adjustment depends on the feeling, but according to this form, since it is not necessary to manually adjust the depression degree of the piston, it can be accurately ejected even with a small desired amount.

In addition, since the pressing body 32B (pressing rib 32Aa) is not brought into contact with any one of the pistons 22B (FIG. 9), unintentional ejection when the pressing body 32B is pressed by mistake can be prevented.

Although the number of the pistons 22B (the number of the combination of the pistons 22B and the cylinders 23B) may be two or more, it is preferably three or more. Thereby, the amount of the contents ejected by pressing the pressing body 32Ba once can be changed in multiple steps.

In the forms shown in FIGS. 6 to 9, the number of the pistons 22B abutted by the pressing ribs 32Ba is changed in accordance with the rotation of the pressing ribs 32Ba by approximately 60 °, but the rotation angle is used to change the number of abutting pistons 22B. It is not limited to those shown in the drawings, and may be appropriately set according to the arrangement of the piston, the size of the upper end surface, the size or shape of the pressing rib 32Ba, and the like.

In addition, when the ejector 10B is used in the arrangement shown in FIGS. 6 to 9, the piston 22Bc among the three pistons 22B operates most frequently, and the operating frequency of the piston 22Ba becomes smaller. Therefore, the contents filled in the cylinder 23Ba corresponding to the piston 22Ba may be held in the ejector 10B for a relatively long period of time. Therefore, the pressing body 32B may be further rotated clockwise by 60 ° from the state shown in FIG. 9 so that the pressing rib 32Ba abuts on the upper end surface of the piston 22Ba. Thereby, only the piston Ba can be actuated, and the content of the same ejection amount as in the case shown in FIG. 8 can be ejected. If the pressing body 32B is further rotated clockwise by 120 ° from the state shown in FIG. 9, and the pressing rib Ba is abutted on the upper end surfaces of the two pistons 22Ba and 22Bb, it can be ejected as shown in FIG. 7. The contents of the same amount of ejection. With this configuration, the frequency of use of each piston 22B can be made uniform, and the cylinder 23B corresponding to the specific piston 22B can be prevented from being filled with contents for a long period of time.

Moreover, in the above-mentioned form, the pressing body 32B is rotatable with respect to the support body 34 and the pump part main body 21 (relative to the piston 22B). However, the pressing body 32B can move in a plane direction orthogonal to the axial direction of the piston 22B. As long as the number of the pistons 22A abutted by the pressing body 32B can be changed by this movement, the movement of the pressing body 32B is not limited to the above-mentioned rotation . For example, the pressing body 32B may be slid in a plane direction (x direction) orthogonal to the axial direction of the piston 22B. In this case, the number of pistons 22B that overlap the pressing body 32B in a plan view can be changed by sliding the pressing body 32B in the x direction.

As shown in FIGS. 1 to 3, in this embodiment, the two ejectors 10A and 10B are combined to constitute the ejection device 100. In the form shown, the ejectors 10A and 10B have the same structure (the number and size of the pistons, the size of the flow channels formed, etc.), but different ejectors can also be combined. The number of combined ejectors may be three or more.

The contents ejected from the ejector 10A and the ejector 10B may be the same or different. When the ejector 10A and the ejector 10B respectively eject different contents, the ejection device 100 of this form can be used as a device for ejecting a plurality of different contents to be mixed for use. According to this aspect, the contents can be simultaneously ejected from the ejector 10A and the ejector 10B.

In the ejection device 100, the support body 34 and the cover body 31 in the pressing portions 30A and 30B, the pump body 21 in the pump portions 20A and 20B, and the frame body 40 may be members common to both ejectors.

In a case where the support body 34 is a component common to the ejector 10A and the ejector 10B, the pressing body 32A and the pressing body 32B can be simultaneously depressed by pressing the supporting body 34. Here, when it can mean that both the pressing body 32A and the pressing body 32B are depressed at the same time, the pressing start time and the pressing end time of both can be made the same. In this way, by having the support body 34 shared by the two ejectors, the contents can be simultaneously ejected from the ejector 10A and the ejector 10B.

In addition, the pressing portion 30A and the pressing portion 30B (pressing body 32A and pressing body 32B) can be pressed in the same process by pressing down the support member 34 which is a common member. That is, the step (distance) of the pressing body 32A and the pressing body 32B whether the pressing operation is performed to the end (until the support body 34 abuts on the upper surface of the pump section body 21 and cannot be pressed further) or is stopped halfway. ) Are all equal. Therefore, the ratio of the amount of the content LA ejected from the ejector 10A to the amount of the content LB ejected from the ejector 10B is the same whether the pressing operation is performed to the end or stopped halfway. That is, in this aspect, when the pressing portions 30A and 30B are depressed by pressing the support 34, the ratio of the contents ejected from each ejector can be fixed. Therefore, when the pressing of the pressing part is stopped intentionally or unintentionally, the contents can be ejected at a desired ratio.

The pressing bodies 32A and 32B can be independently rotated. That is, the number of the pistons 22A abutted and pressed by the pressing body 32A in the ejector 10A and the number of the pistons 22B abutted and pressed by the pressing body 32B in the ejector 10B can be independently changed. Therefore, the amount of content ejected from the ejector 10A and the amount of content ejected from the ejector 10B can be independently set. Therefore, the user can cause each liquid state to be ejected from each ejector in a desired ratio each time it is used.

In the above embodiment, the ejector 10A and the ejector 10B each include three pistons having the same extrusion amount. Therefore, when the arrangement of the pressing body 32A of the ejector 10A and the pressing body 32B of the ejector 10B are adjusted independently, the amount of content LA ejected from the ejector 10A and the content ejected from the ejector 10B can be adjusted separately The ratio of the amount of LB is gradually changed to 1: 1, 1: 1.5, 1: 2, 1: 3. This ratio can be changed by changing the number of pistons provided in each ejector.

In this way, according to the ejection device 100 of this aspect, a plurality of contents having different properties can be mixed and used at different ratios each time they are used. As described above, each ejector can adjust the amount of the liquid state ejected at one time in multiple stages. Therefore, it is not necessary to stop pressing halfway when it is desired to obtain a small amount of total content (mixture). By pressing the pressing portions 30A and 30B and manually adjusting the pressing step, the desired small amount of content can be more accurately ejected by reducing the number of pistons abutted by the pressing body in each ejector, respectively.

In the ejection device 100 of this embodiment, for example, a liquid foundation containing a large amount of a component that enhances the matte feeling and a liquid foundation containing a large amount of a component that enhances the gloss can be stored in the two ejectors 10A and 10B, respectively. And, as long as the knobs 32Ab and 32Bb of each pressing body 32A and 32B are independently adjusted according to the expectations at each use, the ejection amount of the ejector 10A and the ejector 10B can be obtained, and a liquid foundation mixture for obtaining a desired final texture .

This application claims priority based on Japanese Patent Application No. 2018-081782 filed with the Japan Patent Office on April 20, 2018, the entire contents of which are hereby incorporated by reference.
