  A ball valve 22 is disposed on the valve seat 11 b of the housing 11 and controls the inflow of liquid from an inlet 11 c which is an opening at the lower end of the housing 11. Further, at the lower end of the housing 11, the upper end portion of the introduction pipe 23 is inserted and fixed from the introduction port 11c. The introduction pipe 23, the housing 11, the displacement control rod 19, the lower piston 16, the upper piston 13, the pump mounting body 5, and the fitting cylinder 14 a described above are arranged coaxially with the axis X.

  On the other hand, a bottomed cylindrical discharge cylinder 24 having a discharge port 24a at its bottom surface is liquid-tightly fixed to the small diameter opening 3a of the outer liquid storage chamber main body 3, and the discharge port 24a of the discharge cylinder 24 discharges liquid. Make up the department. An external thread 3b is formed on the outer peripheral surface of the small diameter opening 3a. The lower cap 25 provided with an inner cylinder 25a having an inner peripheral surface formed with a female screw 25b which can be screwed with the male screw 3b is screwed with the female screw 25b to the male screw 3b. , And is removed from the small diameter opening 3a by unscrewing.

A bottomed cylindrical upper cap 26 having an upper surface portion is detachably fitted to the container shoulder portion 4 at the lower inner peripheral surface thereof.

  Subsequently, the discharging operation of the above-described embodiment will be described. First, an operation of discharging the liquid such as the cosmetic stored in the outer liquid storage chamber B to the outside will be described. In an initial standby state (state shown in FIG. 1) in which a predetermined amount of liquid (not shown) is stored in the outer liquid storage chamber B, the lower cap 25 is rotated to release the screwed state of the male and female screws 25b and 3b. When the lower cap 25 is removed, the discharge port 24a is exposed. Here, if the container 1 is shaken in the vertical direction so that the discharge port 24a faces downward, the liquid in the outer liquid container chamber B is discharged from the discharge port 24a to the outside in an appropriate amount.

  Next, an operation of discharging the liquid such as the cosmetic stored in the inner liquid storage chamber A to the outside will be described. In the state of FIG. 1, when the upper cap 26 is removed and the drive head 14 is depressed, the upper piston 13 is lowered, and the lower piston 16 is also lowered against the resilient biasing force of the coil spring 18. As a result, the pressure in the housing 11 is increased, and the pressure in the lower housing 16 from the lower piston 16 starts to move from the communication passage 16 c into the upper piston 13 through the lower piston 16.

  When the drive head 14 is further depressed to reach the lowermost position where the lower end of the drive head 14 contacts the upper surface of the pump mounting body 5, the lowering is prevented. In this state, the pressure in the housing 11 is maximized, and the liquid in the housing 11 that has moved almost into the lower piston 16 further moves into the upper piston 13 and is discharged together with the liquid in the upper piston 13. It is discharged from 15.

  Here, when the pressing force applied to the drive head 14 is released, the lower piston 16, the upper piston 13 and the drive head 14 return to the original position by the elastic force of the coil spring 18, and are again in the standby state. At this time, the pressure in the housing 11 becomes smaller than the pressure in the inner liquid storage chamber A, the ball valve 22 is opened, and the liquid in the inner liquid storage chamber A flows into the housing 11 through the introduction pipe 23 To prepare for the next operation.

  Subsequently, a second embodiment of the present invention will be described based on FIGS. 2 to 5. The present embodiment uses a so-called back suction type pump that prevents liquid dripping, and differs from the first embodiment described above only in the fixing structure of the inner liquid storage chamber main body and the configuration related to the pump. It is. Therefore, only the configuration different from that of the first embodiment will be described below, and the same components will be denoted by the same reference numerals as the corresponding components, and the detailed description will be omitted. As shown in FIG. 2, the inner liquid storage chamber main body 42 provided in the container 51 has a step on the lower end inner peripheral surface of the annular inner peripheral wall 4f in the container shoulder 4 at the outer peripheral surface of the thin portion 42a at the upper end thereof. It is liquid-tightly fixed by laser welding.

  As shown in FIGS. 2 to 5, the fitting cylinder 34 a of the drive head 34 is fitted to the substantially cylindrical upper piston 33 located at the upper end of the pump 30. The lower end of the outer peripheral surface of the drive head 34 is located inside of an annular guide wall 35 d integrally erected on the upper surface of the pump mounting body 35. Further, the drive head 34 is provided with a discharge port 34b for discharging liquid so as to communicate with the inside of the upper piston 33 via the fitting cylinder 34a.

  The upper piston 33 is vertically movably supported by the mounting cylinder 35c of the pump mounting body 35, and the lower portion is a large diameter portion 33a to form a stepped portion 33b, the outer diameter surface of the large diameter portion 33a being the mounting cylinder It is formed slidably on the inner peripheral surface of 35c. The upper end portion of the lower piston 36 is fitted and fixed to the upper piston 33. The upper portion of the lower piston 36 has a cylindrical shape and the lower portion has a round rod shape, a skirt portion 36a is formed at the boundary between them, and a pair of upper and lower communicating holes 36b and 36c are provided in the upper portion. Further, at the lower part of the skirt portion 36a, an engagement step portion 36d which protrudes to the outer peripheral side is provided.

  The upper end of the substantially cylindrical housing 31 in which the upper and lower pistons 33 and 36 reciprocate up and down is fitted into the fitting recess 35 b of the pump mounting body 35, and the flange portion 31 a is interposed via the seal ring 32. It is fixed by being clamped from the upper and lower sides by the said pump mounting body 35 and the small diameter opening part 4d. A valve seat 31d is provided on the gradually reduced inner surface of the lower portion of the housing 31, and a ball valve 39 serving as a check valve is disposed on the valve seat 31d. The housing 31 is provided with an air vent 31e, and the opening at the lower end of the cylindrical portion following the valve seat 31d is an inlet 31c. Further, in the vicinity of the ball valve 39, there is disposed a cylindrical stopper 40 having a locking portion 40a which is annular and whose diameter is enlarged at its lower end. The inner diameter of the cylindrical stopper 40 is large enough to allow the round rod portion of the lower piston 36 to plunge.

  A coil spring 37 is disposed between the locking portion 40 a of the cylindrical stopper 40 and the engagement step 36 d of the lower piston 36 to elastically bias the lower piston 36 upward, while the cylindrical stopper 40. Is urged downward. Further, a coil spring 41 is disposed between a stepped portion 40b formed on the upper end inner peripheral surface of the cylindrical stopper 40 and the ball valve 39 to resiliently bias the ball valve 39 downward, so that the cylindrical stopper The 40 is urged upward. The elastic force of the coil spring 41 is set to be weaker than the elastic biasing force of the coil spring 37 and the cylindrical stopper 40 can not be moved upward, while the pressure in the housing 31 is in the inner liquid storage chamber A. The ball valve 39 is set to be in close contact with the valve seat 31d and to maintain the closed state until the pressure is smaller than a predetermined pressure.

  A double annular seal valve 38 connected at a lower portion is slidably disposed between the upper outer peripheral surface of the lower piston 36 and the inner peripheral surface of the housing 31. The seal valve 38 has a large number of flanges formed at intervals along the entire inner circumferential surface of the inner ring 38a, and an appropriate frictional force is applied to the outer circumferential surface between each pair of communication holes 36b and 36c of the lower piston 36. While being in sliding contact with each other, the inner peripheral surface of the housing 31 is in sliding contact with the outer peripheral surface of the upper and lower end portions of the outer ring 38b via an appropriate frictional force. A large number of recessed grooves exist over the entire circumference between the respective protruding edges which are sliding surfaces of the seal valve 38 with the lower piston 36, and the upper and lower spaces are communicated by the recessed grooves.

  In the seal valve 38, the lower end of the inner ring 38a is in close contact with the skirt portion 36a of the lower piston 36 and the upper end of the outer ring 38b is attached to the pump in the standby state where the upper and lower pistons 33 and 36 are at the uppermost position shown in FIG. Close to the lower end of the mounting cylinder 35c of the body 35, the space in the housing 31 and the space in each of the upper and lower pistons 33, 36 are shut off. On the other hand, at the end of discharge when the upper and lower pistons 33 and 36 shown in FIG. 4 are at the lowermost position, the lower end of the outer ring 38b is in close contact with the step 31b of the housing 31 and the upper end of the inner ring 38a is closed. Close to the step 33 b of the upper piston 33, the space in the housing 31 and the space in each of the upper and lower pistons 33, 36 are in communication.

  Subsequently, although the discharge operation of the above-described embodiment will be described, the discharge operation from the discharge port 24a is the same as that of the first embodiment described above, so the description thereof will be omitted, and only the discharge operation of the pump 30 will be described. . When the upper cap 26 is removed and the drive head 34 is depressed in a standby state (see FIG. 2) in which a predetermined amount of liquid (not shown) is stored in the inner liquid storage chamber A, the upper and lower pistons 33 and 36 are also The skirt portion 36a of the lower piston 36 moves away from the lower end of the inner ring 38a of the seal valve 38 and descends against the elastic force of the coil spring 37, and the space in the housing 31 and the lower piston 36 The space is brought into communication with each other via the communication hole 36 b and the concave groove and the communication hole 36 c. The pressure in the space below the skirt portion 36a in the housing 31 is increased, and the fluid in the space below the skirt portion 36a passes through the communication hole 36c by this pressure, and from the concave groove of the seal valve 38 to the communication hole Begin to move into the lower piston 36 through 36b.

  As the drive head 34 descends, the step 33b of the upper piston 33 closely contacts the upper end of the inner ring 38a of the seal valve 38, and the seal valve 38 descends together with the upper and lower pistons 33 and 36. When the pressure in the space below the portion 36a further increases, the liquid in the upper and lower pistons 33 and 36 starts to be discharged from the discharge port 34b (see FIG. 3). When the drive head 34 is further pushed down and the lower end of the outer ring 38 b of the seal valve 38 closely contacts the step 31 c of the housing 31, the lower end of the skirt 36 a is locked to the upper end of the cylindrical stopper 40. This prevents descent and lower piston 36 reaches its lowermost position (see FIG. 4). In this state, the pressure on the liquid in the housing 31 is maximized, and the operation of discharging the liquid from the discharge port 34b is completed. Then, the liquid remains in the discharge port 34b, and depending on the viscosity of the liquid, the liquid is projected from the discharge port 34b by surface tension.

  Here, when the pressing force applied to the drive head 34 is released, the upper and lower pistons 33 and 36 move upward by the elastic force of the coil spring 37, so the volume in the housing 31 increases and the inner liquid storage chamber A pressure is negative with respect to A, and the liquid in the upper and lower pistons 33 and 36 is drawn into the housing 31 through the communication hole 36b, the concave groove and the communication hole 36c, and the liquid remaining in the discharge port 34b The upper and lower pistons 33, 36 are retracted (see FIG. 5). This prevents dripping.

  At this time, the ball valve 39 is kept in close contact with the valve seat 31d by the elastic force of the coil spring 41, so that the liquid in the inner liquid storage chamber A is in the housing 31 even if the pressure in the housing 31 decreases. The negative pressure in the housing 31 is maintained, and the liquid in the upper and lower pistons 33 and 36 described above is drawn into the housing 31 through the communication hole 36 b and the recessed groove and the communication hole 36 c. The suction operation and the suction operation for drawing the liquid remaining in the discharge port 34a into the upper and lower pistons 33, 36 are reliably performed. Further, since the liquid is drawn from the pair of upper and lower communication holes 36b and 36c, the suction operation is performed more quickly than in the case of one communication hole.

  When the upper and lower pistons 33 and 36 move up and the lower end of the inner ring 38a of the seal valve 38 abuts on the skirt portion 36a, the inside of the housing 31 and the upper and lower pistons 33 and 36 are shut off. The suction operation is stopped, and the seal valve 38 ascends with the upper and lower pistons 33, 36. When the upper and lower pistons 33 and 36 further rise, the pressure in the housing 31 becomes smaller, and when the pressure falls below a predetermined pressure, the ball valve 39 is opened against the elastic force of the coil spring 41 and the housing The liquid in the inner liquid storage chamber A flows into the space 31. When the pressure in the housing 31 reaches a certain level or more by this inflow, the ball valve 39 returns to the closed state again by the elastic force of the spring 41, and the inside of the housing 31 and the inside of the inner liquid storage chamber A are disconnected.

  When the upper and lower pistons 33, 36 are further raised and the upper end of the outer ring 38b of the seal valve 38 abuts on the lower end of the mounting cylinder 35c of the pump mounting body 35, the drive head 34, the upper and lower cylinders 33, 36 and the seal valve The lifting operation of 38 is stopped, and a standby state (see FIG. 2) is prepared for the next operation.

  Subsequently, a third embodiment of the present invention will be described based on FIG. The present embodiment is different from the above-described first and second embodiments in that the liquid in the inner liquid storage chamber A is discharged from the discharge port, and the liquid in the outer liquid storage chamber B is discharged by a pump. The configuration of the pump is identical to that of the second embodiment except for the length of the introduction pipe. Therefore, only different configurations will be described below, and the same components as those of the first and second embodiments will be denoted by the same reference numerals as the corresponding components, and detailed description will be omitted.
