  • 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.
  • 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.
  • 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.
  • 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.
  • the discharge amount can be changed in the same pressing process.
  • 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.
  • 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.
  • 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.
  • 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).
  • 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.
  • 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.
  • a discharge device 100 is configured by combining two discharge devices 10A and 10B.
  • 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.
  • the contents discharged from the discharger 10A and the discharger 10B may be the same or different.
  • 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.
  • 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.
  • the pressing body 32A and the pressing body 32B can be simultaneously pressed by pressing the support body 34.
  • 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.
  • the support body 34 common to both dischargers, the contents can be discharged simultaneously from the dischargers 10A and 10B.
  • the pressing portion 30A and the pressing portion 30B 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. .
  • 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.
  • 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.
  • a plurality of contents having different properties can be mixed and used at different ratios depending on the time of use.
  • 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)
  • 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.
  • 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.
