In addition, when the piston pressing member 83 moves together with the piston activation member 70 and the piston member 60 is lowered, a predetermined pressure is applied to the piston member 60 through the flow path r1 until the guide main body 81 is relatively raised. As shown in FIG. 3, the space between the piston member 60 and the piston guide 80 is sealed by contacting the lower end portion 61 a of the inner cylinder portion 61. As a result, a pump chamber R4 is formed in the cylinder 42 in cooperation with the suction valve 50.

  Further, a flow hole A4 is formed in the side surface of the guide body 81. In addition, an internal passage r2 communicating with the flow path r1 through the circulation hole A4 is formed inside the guide body 81. As shown in FIG. 3, the internal passage r <b> 2 can be closed together with the flow hole A <b> 4 by sealing between the piston member 60 and the piston guide 80. For this reason, as described above, if the piston member 60 rises along the guide main body 81 due to the pressure rise in the cylinder 42, the flow hole A4 can be opened and the flow path r1 can be communicated with the internal passage r2.

  In this embodiment, the cylinder 42 of the cylinder member 40 and the piston fitting portion 72 of the piston activation member 70 are sealed with an annular seal member 130. The seal member 130 expands to the support cylinder 44 of the cylinder member 40, and seals between the cylinder member 40 together with the inner peripheral surface of the support cylinder 44.

  Accordingly, the pump P can suck, pressurize, and pump the contents by repeatedly pressing and returning the piston activation member 70.

  Here, a plurality of projecting portions 76 are integrally provided on the top wall 71 of the piston activation member 70 at intervals around the axis O. Each protrusion 76 is inserted through a through-hole A5 formed in the flat wall 35 that surrounds the tray portion 36, and thus stands outside through the through-hole A5. Further, a ring button 90 made of synthetic resin is disposed at the upper end of the protruding portion 76 so as to surround the tray portion 36. The ring button 90 has a flat annular pressing wall 91. The pressing wall 91 is formed with an opening A6 through which the tray portion 36 passes. In this embodiment, as shown in FIG. 2, the opening A <b> 6 is formed in a flat, substantially elliptical cross-sectional shape, like the tray portion 36. The ring button 90 has an outer cylindrical wall 92 that can accommodate the tray portion 36 inside. In the present embodiment, the outer cylindrical wall 92 hangs down integrally from the outer edge of the pressing wall 91 as shown in FIG. The ring button 90 is fixed to the protruding portion 76 by using adhesion, fixing means C1, or the like. Thereby, as shown in FIG. 5 (FIG. 1 or 3), the ring button 90 is fixedly held by the piston actuating member 70 in a state where the tray main body 36b is projected.

  In this embodiment, the tray member 36 is provided on the cover member 30 that closes the container body 10, and the protruding portion 76 of the piston activation member 70 is raised through the through hole A5 formed in the flat wall 35 that surrounds the tray portion 36. Since the ring button 90 that surrounds the tray portion 36 is disposed in the protruding portion 76, when the ring button 90 is pushed in from the state shown in FIG. 5 after the overcap 150 is removed, the ring button 90 is biased by the elastic member S. As shown in FIG. 4, the piston member 60 can be moved down together with the piston activation member 70 by pushing down the piston activation member 70 downward. Next, if the pushing of the ring button 90 is released, the piston activation member 70 rises due to the urging force of the elastic member S, so that the piston member 60 is restored to the initial position together with the piston activation member 70 as shown in FIG. Can do. During this time, the piston member 60 opens and closes the flow hole A4 in accordance with the pressure in the pump chamber R4, and performs suction, pressurization, and pumping of the contents. Therefore, if the ring button 90 is repeatedly pushed and released, the contents of the container body 10 are received through the opening A1 by ejecting the contents from the opening A1 of the receiving part 36 provided in the cover member 30. The main body 36b can be taken out.

  In addition, the middle tray 20 disposed in the container body 10 rises as the contents are ejected. For this reason, since the contents can be efficiently taken out from the filling space R1, the residual in the filling space R1 can be suppressed.

  Further, as shown in FIG. 3, when the piston activation member 70 is in the initial position, the plug 73 provided on the piston activation member 70 seals the opening A <b> 1 of the tray portion 36. Thereby, the deterioration of the operativity which arises when the content adhering to opening A1 dries and solidifies can be prevented.

  Therefore, according to the present invention, it is possible to provide a novel pump-type ejection container provided with an intermediate tray that can take out the contents into the receiving tray portion 36 without using a pressing head and has good operability. it can.

  Further, in this embodiment, as shown in FIG. 3, when the piston activation member 70 is in the initial position, the variable passage that leads from the lower end of the cylindrical portion 36d to the internal passage r3 is between the stem portion 74 and the cylindrical portion 36d. Since the capacity space R3 is formed, the variable capacity space R3 is reduced by the return of the piston activation member 70 when the push-in is released after the variable capacity space R3 is reduced as shown in FIG. When increased again as shown in FIG. 3, back suction (retraction of contents) due to the negative pressure caused by the increase in the variable capacity space R3 occurs in the internal passage r3 formed in the cylindrical portion 36d. For this reason, since the contents adhering to the opening A1 are sucked into the internal passage r3 and the variable capacity space R3, it becomes difficult for the contents to adhere to the opening A1, so that the operability deteriorates due to solidification of the adhering matter. It is effective for prevention.

  Further, in this embodiment, as shown in FIG. 2, the tray portion 36 has a flat shape in which the cross-sectional shape thereof is a flat shape in which partial areas facing each other with respect to a perfect circle are brought close to each other. Since a wide pressing area (operation area) of the button 90 can be secured, the operability is further improved. Further, in this embodiment, since the raised portion 36c surrounding the opening A1 is formed in the saucer body 36b, the taken-out contents spill out and enter the gap between the ring button 90, and the saucer portion 36 And the ring button 90 can be prevented from sticking to each other.

  What has been described above is one embodiment of the present invention, and various modifications can be made within the scope of the claims. For example, the shape of the tray portion is not limited to an elliptical shape, and a perfect circular shape or the like can be adopted. Further, the bottom wall of the container body can be omitted. The cover member and the cylinder member can be assembled to the container body without being fixed.

  The present invention is not limited to a stationary type or a handy type. In addition, the contents are not limited to cosmetics, and hair styling and the like can be employed.
