Description

Discharger and discharge device

The present invention relates to a discharger and a discharge device.

A manual pump type discharge device is known that discharges the contents stored in the container. Such a discharge device is generally configured such that the piston is pushed down by a pressing body provided in a nozzle head or the like, and the contents are discharged (discharged) to the outside at that time (for example, Patent Documents). 1).

JP-A-8-337263

In the dispenser disclosed in Patent Document 1, a predetermined amount of content is discharged by a single depression of the piston. However, when it is desired to discharge a content smaller than the predetermined amount, it is necessary to manually adjust the degree of depression so that the piston stops in the middle of the depression process. Since it is not easy to perform such manual adjustment accurately, it is difficult to accurately perform a small amount of discharge in a conventional discharger.

In view of the above points, an object of one embodiment of the present invention is to provide a discharger that can accurately discharge a desired amount even when a small amount is discharged.

In order to solve the above problems, a discharge device according to an aspect of the present invention includes a container that stores contents, a pump unit that discharges the contents, and a plurality of pistons that are in contact with the piston. A pressing body capable of pushing down the piston, and the pressing body is movable with respect to the pump unit along a plane orthogonal to the axial direction of the piston, and abuts by the movement of the pressing body. The number of pistons can be changed.

According to one aspect of the present invention, there is provided a discharger that can accurately discharge a desired amount even when a small amount is discharged.

It is a figure explaining the function of a discharger. It is a figure explaining the function of a discharger. It is a figure explaining the function of a discharger.

Hereinafter, modes for carrying out the present invention will be described with reference to the drawings, but the present invention is not limited to the embodiments described in the present specification. In the following description, the x direction, the y direction, and the z direction are directions perpendicular to each other, the x direction and the y direction are horizontal directions, and the z direction is a vertical direction. In the present specification, the lower side means the lower side in the vertical direction, and the upper side means the upper side in the vertical direction.

FIG. 1 shows a perspective view of this embodiment. FIG. 1 shows a discharge device 100 including two

dischargers

10A and 10B as an example. FIG. 2 is an exploded view of the discharge device 100 of FIG. Further, FIG. 3A shows a cross-sectional view taken along line II (II arrow view) of the discharge device 100 of FIG. 1, and FIG. 3B shows a top view.

The

dischargers

10A and 10B are configured to discharge the contents accommodated in the discharger to the outside by a pump. The content is not limited as long as it shows fluidity at the time of discharge and can be extruded from the discharge port, and can be a fluid containing a liquid (liquid material), a powder, or the like. Further, the content may be a solution, a dispersion such as an emulsion or a suspension, and may be in a state called a gel, slurry, paste, cream or the like. When the content is a liquid (liquid material), it may be in a state having a viscosity close to that of water, or may be in the form of a viscous cream. For example, the viscosity of the contents is preferably 3000 to 150,000 mPa · s at 30 ° C., and more preferably 5000 to 30000 mPa · s. The contents include, for example, an oily component, an aqueous component, a surfactant, a film agent, a powder, a pigment, a drug, etc., and a lotion, emulsion, sunscreen, foundation, makeup base, concealer, eye shadow, lip It can be applied to applications such as products, hair care products, and fragrance products. The contents include those that are mixed with a gas such as air and discharged in the form of foam (form), or those that are contained in foam.

In the following, the configuration and function of each discharger will be described first. In the illustrated embodiment, the structures of the

ejectors

10A and 10B are bilaterally symmetric (plane symmetric with respect to the plane along the y direction), and the basic configuration and function are the same. Therefore, the ejector 10A will be described as a representative. As will be described later, there are members common to the

ejectors

10A and 10B (members shared by the

ejectors

10A and 10B). For such common members, the reference numeral A or B is the reference number. Not attached.

As shown in FIGS. 1 to 3, the discharger 10A includes a container 50A for storing contents, a pump unit 20A for discharging contents stored in the container 50A to the outside, and a pump unit 20A. And a pressing portion 30A for pressing the inner movable element (piston).

As shown in FIG. 2, the pump unit 20A has a plurality of pistons 22Aa, 22Ab, and 22Ac (sometimes referred to as 22A together). Furthermore, the pump part 20A has a pump part main body 21, and cylinders (through holes) 23Aa, 23Ab, and 23Ac corresponding to the number of pistons 22A are formed in the pump part main body 21. In the illustrated form, the number of pistons 22A (that is, the number of cylinders 23A) is three, but the number of pistons 22A is not limited to three as long as it is plural. One end (the end on the container 50A side or the content LA side) of each piston 22A is inserted into each of the plurality of cylinders 23A, and can be slid in a liquid-tight manner with respect to the cylinders 23A.

The housing 40 is disposed below the pump body 21. The casing 40 is liquid-tightly coupled to the pump body 21 by fitting or the like. As shown in FIG. 2 and FIG. 3 (a), since a recess is formed in the upper part of the housing 40, a space is formed by coupling the housing 40 and the pump unit body 21. A flow path 27A through which the object LA passes can be formed. The flow path 27 A communicates with a discharge port (nozzle) 24 A formed on the side surface of the pump unit main body 21.

2 and 3A, a plurality of

dischargers

10A and 10B are juxtaposed along the x direction, and the pump body 21 and the casing 40 are common to the

dischargers

10A and 10B. In this case, the flow path 27A does not communicate with the flow path 27B of the adjacent discharger 10B. Specifically, a concave portion 43A for the discharge device 10A and a concave portion 43B for the discharge device 10B are separately formed on the upper portion of the common casing 40. In other words, it can be said that the flow path 27A and the flow path 27B are partitioned by the partition 44.

The housing 40 has a function of covering the container 50A and protecting the container 50A. The container 50A can be attached to the upper part of the housing 40 from below (from the inside of the housing 40). In the illustrated form, a screw is cut on the side surface of the opening 51A of the housing 50A, and a screw that is screwed to the side surface of the opening of the housing 50A is also formed on the lower surface of the upper portion of the housing 40. Yes. However, the container 50A may be attached to the housing 40 by another form such as fitting.

It is preferable that the container 50A is detachably attached to the housing 40. Thereby, when the inside of the container 50A becomes empty or the content in the container 50A decreases, the container can be replaced with a new container filled with the contents. And pump part 20A and press part 30A can be used continuously. Further, when the container 50A is empty or the contents in the container 50A are reduced, the container 50A is temporarily removed from the housing 40, filled with the contents, and then attached to the housing 40 again. You can also.

As shown in FIG. 3, a suction port 41 A that communicates with the inside of the attached container 50 A is formed in the upper portion of the housing 40. The suction port 41A communicates with a suction pipe 42A extending to the container 50A. When the pump unit 30A operates, the content LA is sucked up from the tip of the suction pipe 42A and flows into the flow path 27A through the suction port 41A.

The container 50A can be configured as a so-called airless container. For example, the container 50A can be configured by an outer container and a flexible inner bag that is detachably mounted inside the outer container, and the contents can be stored in the inner bag. And the structure which sucks the contents from the suction port while reducing the volume of the inner bag by the action of the pump part, and sends air between the inner bag and the outer container through the air inflow hole formed in the outer container It can be. Alternatively, an inner tray is slidable up and down inside the container, and the upper portion of the inner tray is used as the content storage portion, and the volume of the storage portion is reduced by raising the intermediate tray by the action of the pump unit. The contents can be discharged while being discharged. Such a structure of the airless container is suitable for accommodating contents whose properties are easily deteriorated or changed by contact with air.

The pressing portion 30A includes a pressing body 32A that can press down the plurality of pistons 22A. In the illustrated form, the pressing body 32A has a cup-like shape (FIG. 2), and a pressing rib 32Aa protruding downward is formed on the inner side (lower side) (FIG. 3A). )). The pressing rib 32Aa can come into contact with the upper end surfaces (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 pushed down, the piston 22A with which the pressing rib 32Aa comes into contact is pushed down. FIG. 3A shows that the pressing rib 32Aa is in contact with 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 (side where the piston 22A is disposed). The pressing rib 32Aa protruding from the lower side (inner side) of the pressing body 32A has a continuous belt-like shape that curves along the outer edge of the pressing body 32A in plan view. However, the shape of the pressing rib 32Aa in plan view may not be along the outline of the outer edge of the pressing body 32A or may be discontinuous as long as the number of pistons 22A that are in contact by movement (rotation) can be changed. It may be. Further, the pressing body 32A includes a cylindrical protrusion 32Ac that protrudes downward in the center in plan view (FIGS. 3A and 4). The cylindrical protrusion 32Ac is configured to engage with a protrusion 34Aa of a support 34 described later. In the illustrated embodiment, the pressing rib 32Aa is coupled to the cylindrical projection 32Ac, that is, extends from the cylindrical projection 32Ac, but the two may not be coupled. However, the illustrated embodiment in which the pressing rib 32Aa and the cylindrical protrusion 32Ac are coupled is preferable because the strength can be improved.

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

1 to 3, the pressing body 32A may be covered with a lid 31. In the illustrated embodiment, the pressing body 32A has a knob 32Ab that can be operated by the user protruding upward, so that the lid 31 is provided so as not to obstruct the protruding portion and the movable range of the knob 32Ab. Therefore, the lid 31 can 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 (FIGS. 2 and 3B).

The pressing body 32A is supported by the support body 34. The support body 34 and the pressing body 32A are configured to move together in the vertical direction. The support body 34 can be pushed down so as to approach the pump body 21 provided on the lower side thereof, and the pressing body 32A is pushed down together with the support body 34 in accordance with the movement. When the support body 34 is pushed up, the pressing body 32A is also pushed up with the movement.

In the illustrated form, 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 with respect to the protrusion 34Aa of the support body 34, the pressing body 32A can be rotated about the protrusion 34Aa of the support body 34 (centering on the central axis of the protrusion 34Aa). .

A spring 35 is provided below the support 34. When the user applies pressure to the support 34 and pushes it down, the spring 35 is compressed and biased. And if a user cancels | releases the pressurization to the support body 34, the support body 34 will be pushed up by the restoring force of the spring 35, and can return to the original position.

Further, a guide protrusion 34b may be provided on the lower side of the support 34. The guide protrusion 34b is inserted into a hole 21a formed on the upper side of the pump body 21 and can slide within the hole 21a. The spring 35 may also be disposed in the hole 21a, and the guide protrusion 34b of the support 34 may be inserted into the spring 35. As described above, the guide protrusion 34b of the support 34 is inserted into the hole 21a of the pump body 21 and is slidable, so that the support 34 can be stably moved along the vertical direction (z direction). In addition, the spring 35 can be stably compressed and deformed.

As shown in FIG. 3 (a), holes corresponding to the plurality of pistons 22A are formed in the support body 34, 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, when the support body 34 is pushed upward and returned to the original position as described above, the upper portion of the piston 22A comes into contact with the portion of the support body 34 surrounding the hole, and the upper side together with the support body 34. Lifted to.

FIG. 5 schematically shows the flow of the contents LA due to the operation (pump action) of the pump unit 20A. FIG. 5 shows a partial view of the cross section taken along the line II-II of FIG. The cross section taken along line II-II is a cross section passing through one of the plurality of pistons 22A (piston 22Ac) and the discharge port 24A.

As described above, the concave portion 43 A is provided in the upper portion of the housing 40, and the housing 40 and the pump unit main body 21 are closely coupled, so that a sealed space is formed between the housing 40 and the pump unit main body 21. A flow path 27A that is formed and communicates from the container 50A to the discharge port 24A is formed. That is, the contents LA can flow from the inside of the container 50A through the suction port 41A formed in the upper portion of the housing 40 toward the discharge port 24A.

A suction valve 26A is disposed on the container 50A side of the flow path 27A (FIGS. 3A and 5). The suction valve 26A can prevent the contents once flowing into the flow path 27A from returning to the container 50A. In the illustrated form, the suction valve 26A is a ball valve, but the form of the valve is not limited to that illustrated. The suction valve 26A may be lightly pressed by a spring or the like so as not to be opened at an undesired timing under the influence of a slight pressure fluctuation in the flow path 27A.

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

The piston 22Ac is slidably inserted into the cylinder 23Ac in a liquid-tight manner. The pressing rib 32Aa of the pressing body 32A is in contact with the upper end surface of the piston 22Ac. Therefore, when the user applies pressure to the pressing portion 30A and the pressing rib 32Aa of the pressing body 32A is pressed downward, the piston 22Ac is pressed down. Thereby, the content filled in the cylinder 23Ac is pushed out, and the pressure in the flow path 27A is increased. As a result, the valve body 25Aa of the discharge valve 25A moves upward and opens. When the discharge valve 25A is opened, the contents LA can be discharged to the outside through the discharge port 24A. At this time, the suction valve 26A provided in the upper part of the housing 40 is pressed to the container 50A side due to the pressure increase in the flow path 27A, so that the suction valve 26A is kept closed. Therefore, the content LA can be prevented from flowing backward from the flow path 27A into the container 50A.

After the discharge of the contents LA, when 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 biased spring 35 (FIGS. 2 and 3A). Is returned to the original position. As described above, since the diameter of the upper portion of the piston 22Ac is larger than that of the central portion, the piston 22Ac is also moved upward and lifted upward as the support body 34 is pushed up. Thereby, the pressure in the cylinder 23Ac (pressure in the flow path 27A) is reduced. The suction valve 26A is opened by this pressure drop, and the content LA stored in the container 50A is sucked into the flow path 27A through the suction pipe 42A and the suction port 41A. On the other hand, since the inside of the flow path 27A is depressurized by lifting the piston 22Ac, the discharge valve 25A is maintained in a closed state, so that the content LA is not discharged.

Note that the pump type of the pump unit 20A in the discharger 10A is not limited to the illustrated one. The shape of the flow path, the arrangement of the valves, and the like can be changed as appropriate. Also, the pressing operation of the piston can be performed electrically.

Next, the relationship between the rotation of the pressing body and the number of pistons pressed against the pressing body will be described with reference to FIGS. 6 to 9 are partial views of the discharger 10B. 6A to 9B, a partial top view of the pressing portion 30B from which the lid 31 has been removed is shown as (a), and a cross-sectional view taken along the line III-III in FIG. As shown. 6 to 9, the arrangement of the pressing rib 32Ba is changed by the rotation of the pressing body 32B.

6A, the pressing rib 32Ba overlaps the upper end surfaces of the three pistons 22Ba, 22Bb, and 22Bc when viewed from above. That is, as shown in FIG. 6B, the pressing rib 32Ba is in contact with the upper end surfaces of the three pistons 22Ba, 22Bb, 22Bc. Therefore, when the pressing portion 30B is pressed down, that is, when the pressing rib 32Ba is pressed down, the three pistons 22Ba, 22Bb, and 22Bc are all pressed down by the pressing rib 32Ba. Thereby, all the pumps by the three pistons 22Ba, 22Bb, and 22Bc can be operated.

FIG. 7 shows a state after the pressing body 32B is rotated 60 ° clockwise from the state shown in FIG. As shown in FIG. 7A, the pressing rib 32Ba overlaps the upper end surfaces of the pistons 22Bb and 22Bc when viewed from above. That is, as shown in FIG. 7B, 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 (the pressing rib 32Ba) is pressed down, the two pistons 22Bb and 22Bc are pressed down, and the piston 22Ba is not pressed down.

In the arrangement of the pressing body 32B shown in FIG. 7, the number of operating pistons is smaller than in the state shown in FIG. Therefore, a smaller amount of contents can be discharged in the same pressing process of the pressing rib 32Ba. More specifically, if the amount of the content pushed out by each piston of the pistons 22Ba, 22Bb, and 22Bc in this embodiment is the same, the arrangement of the pressing body 32B in FIG. Compared with the case, the discharge amount of the contents is two thirds.

FIG. 8 shows a state after the pressing body 32B is further rotated by 60 ° clockwise from the state shown in FIG. As shown in FIG. 8A, the pressing rib 32Ba overlaps with the upper end surface of the piston 22Bc in a top view and does not overlap with the upper end surfaces of the pistons 22Ba and 22Bb. That is, as shown in FIG. 8B, the pressing rib 32Ba is in contact with only the upper end surface of one piston 22Bc. Therefore, when the pressing portion 30B (the pressing rib 32Ba) is pressed down, the piston 22Bc is pressed down, and the other pistons 22Ba and 22Bb are not pressed down.

In the arrangement of the pressing body 32B shown in FIG. 8, the number of operating pistons is smaller than in the state shown in FIGS. If the amount of the content pushed out by each piston is the same, the arrangement of the pressing body 32B in FIG. 8 is pushed out in the same pressing process of the pressing rib 32B as compared with the arrangement of the pressing body 32B in FIG. The discharge amount of the contents can be reduced to one third.

FIG. 9 shows a state after the pressing body 32B is further rotated by 60 ° clockwise from the state shown in FIG. As shown in FIG. 9A, the pressing rib 32Ba does not overlap the upper end surface of any piston 22B when viewed from above. That is, as shown in FIG. 8B, the pressing rib 32Ba does not contact the upper end surface of any piston 22B. Therefore, even if the pressing portion 30B (pressing body 32B) is pushed down, the piston 22B is not pushed down, and the discharge of the contents does not occur.

Thus, in this embodiment, the number of pistons 22B with which the pressing body 32B abuts can be changed by rotating the pressing body 32B relative to the piston 22B (pump portion 20B). Therefore, the discharge amount can be changed in the same pressing process. Conventionally, when it is desired to discharge a small amount less than the discharge amount discharged in one press-down process, it is necessary to manually adjust the push-down state of the piston to perform the discharge operation. However, according to the present embodiment, since it is not necessary to manually adjust the degree of depression of the piston, it is possible to accurately discharge even a small desired amount.

Further, since the pressing body 32B (pressing rib 32Aa) can be brought into a state where it does not come into contact with any of the pistons 22B (FIG. 9), unintended discharge when the pressing body 32B is accidentally pushed down can be prevented.

The number of pistons 22B (the number of combinations of pistons 22B and cylinders 23B) may be two or more, but is preferably three or more. Thereby, the quantity of the content discharged by one depression of pressing body 32Ba can be changed in multiple steps.

In the form shown in FIGS. 6 to 9, the number of pistons 22B with which the pressing ribs 32Ba abut is changed every time the pressing ribs 32Ba are rotated by about 60 °, but the number of pistons 22B with which they abut is changed. The rotation angle for changing is not limited to the illustrated one, and can be set as appropriate depending on the arrangement of the piston, the size of the upper end surface, the size and shape of the pressing rib 32Ba, and the like.

6 to 9, when the discharger 10B is used, the piston 22Bc of the three pistons 22B operates most frequently, and the frequency of the operation of the piston 22Ba is reduced. There is. Therefore, the contents filled in the cylinder 23Ba corresponding to the piston 22Ba may be held in the discharger 10B for a relatively long time. Therefore, from the state shown in FIG. 9, the pressing body 32B can be further rotated 60 ° clockwise so that the pressing rib 32Ba abuts on the upper end surface of the piston 22Ba. Thereby, only piston Ba can be operated and the content of the same discharge amount as the case shown in FIG. 8 can be discharged. Further, when the pressing body 32B is further rotated 120 ° clockwise from the state shown in FIG. 9 so that the pressing rib Ba contacts the upper end surfaces of the two pistons 22Ba and 22Bb, the case shown in FIG. The same discharge amount of contents can be discharged. With such a configuration, it is possible to make the usage frequency of each piston 22B uniform and prevent the contents from being filled in the cylinder 23B corresponding to the specific piston 22B for a long period of time.

Further, in the above-described embodiment, the pressing body 32B is rotatable with respect to the support body 34 and the pump section main body 21 (relative to the piston 22B). However, if the pressing body 32B is movable along the surface direction orthogonal to the axial direction of the piston 22B and the number of pistons 22A with which the pressing body 32B abuts can be changed by this movement, the pressing body The movement of 32B is not limited to the rotation described above. For example, the pressing body 32B may be slidable along a surface direction (x direction) orthogonal to the axial direction of the piston 22B. In that case, by sliding the pressing body 32B along the x direction, the number of pistons 22B overlapping the pressing body 32B in a plan view can be changed.

As shown in FIG. 1 to FIG. 3, in this embodiment, a discharge device 100 is configured by combining two

discharge devices

10A and 10B. In the illustrated form, the

dischargers

10A and 10B have the same configuration (number and size of pistons, size of the flow path to be formed, etc.), but it is also possible to combine dischargers having different configurations. Further, the number of ejectors to be combined may be three or more.

Further, the contents discharged from the discharger 10A and the discharger 10B may be the same or different. When the

discharge devices

10A and 10B discharge different contents, the discharge device 100 of this embodiment can be used as a device that discharges a plurality of different contents to be used immediately before mixing. According to this embodiment, the contents can be discharged simultaneously from the discharger 10A and the discharger 10B.

In the discharge device 100, the support 34 and the lid 31 in the

pressing portions

30A and 30B, the pump main body 21 in the

pump portions

20A and 20B, and the housing 40 can be members common to both dischargers.

When the support body 34 is a member common to the discharger 10A and the discharger 10B, the pressing body 32A and the pressing body 32B can be simultaneously pressed by pressing the support body 34. Here, being able to be pressed down simultaneously means that when the pressing body 32A and the pressing body 32B are pressed down, the pressing start timing and the pressing end timing of both can be made the same. Thus, by having the support body 34 common to both dischargers, the contents can be discharged simultaneously from the

dischargers

10A and 10B.

Further, the pressing portion 30A and the pressing portion 30B (the pressing body 32A and the pressing body 32B) can be pressed down in the same stroke by pressing down the support body 34 which is a common member. That is, the pressing body 32A and the pressing body 32B are pressed down whether the pressing operation is performed to the end (until the support body 34 comes into contact with the upper surface of the pump body 21 and can no longer be pressed) or stopped halfway. The process (distance) is equal. Therefore, the ratio between the amount of content LA discharged from the discharger 10A and the amount of content LB discharged from the discharger 10B is the same whether the pressing operation is performed to the end or stopped halfway. . That is, in this embodiment, when the

pressing portions

30A and 30B are pushed down by pushing down the support body 34, the ratio of the contents discharged from each discharger can be made constant. Therefore, even if it is a case where pressing of a press part is stopped on the way intentionally or unintentionally, the content can be discharged by a desired ratio.

The

pressing bodies

32A and 32B can rotate independently of each other. That is, the number of pistons 22A that the pressing body 32A abuts and pushes down in the discharger 10A and the number of pistons 22B that the pressing body 32B abuts and pushes down in the discharger 10B can be changed independently. For this reason, the amount of content discharged from the discharger 10A and the amount of content discharged from the discharger 10B can be set independently. Therefore, the user can discharge each liquid state from each discharge device at a desired ratio for each use.

In the above-described embodiment, each of the discharger 10A and the discharger 10B includes three pistons having the same amount of extrusion. Therefore, when the arrangement of the pressing body 32A of the discharger 10A and the pressing body 32B of the discharger 10B is adjusted independently, the amount of the content LA discharged from the discharger 10A and the content LB discharged from the discharger 10B. The ratio with respect to the amount can be changed in steps of 1: 1, 1: 1.5, 1: 2, 1: 3. This ratio can be changed by changing the number of pistons provided in each discharger.

Thus, according to the ejection device 100 of the present embodiment, a plurality of contents having different properties can be mixed and used at different ratios depending on the time of use. In addition, as described above, in each discharger, the amount of liquid state discharged by one press can be adjusted in multiple stages, so if you want to obtain a small amount of contents as a total (mixture) By reducing the number of pistons with which the pressing body abuts in each dispenser, the

pressing portions

30A and 30B are stopped halfway and the desired small amount of content can be removed without manually adjusting the pressing process. It can be discharged more accurately.

In the ejection device 100 according to the present embodiment, for example, a foundation containing a lot of components that improve the mat feeling and a foundation containing a lot of components that improve the gloss feeling can be accommodated in the two

ejectors

10A and 10B, respectively. . The foundation for obtaining a desired finished texture can be obtained by independently adjusting the discharge amounts of the discharger 10A and the discharger 10B with the knobs 32Ab and 32Bb of the respective

pressing bodies

32A and 32B as desired at the time of use. A mixture can be obtained.
