  Hereinafter, a fluid storage container according to a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view showing a fluid storage container according to the first embodiment of the present invention.

  This fluid storage container is a gel generally referred to as a gel such as a hair gel or a cleansing gel used in the field of beauty, or a creamy product such as a nutritional cream or a massage cream, or a lotion. It is used as a container for cosmetics for storing liquids and the like. In addition, you may use this fluid storage container as containers, such as a general chemical | medical agent, a solvent, or a foodstuff. In this specification, a high-viscosity liquid, a semi-fluid, or a gel or cream-like substance obtained by solidifying a sol in a jelly form and a normal liquid are referred to as a fluid.

  The fluid storage container has an opening 11 at the top and a cylinder 12 at the side, and is disposed in a container main body 10 for storing the fluid therein and an opening 11 formed in the container main body 10. A discharge port member 20, a tube member 30 having a flow path 31 extending from the bottom of the container body 10 to the discharge port member 20, and a piston member 40 that moves within the cylinder portion 12 of the container body 10. With this configuration, the fluid storage container can store the fluid in the space formed between the bottom of the container body 10 and the piston member 40. The fluid storage container includes an inflow valve mechanism 50 that allows the fluid stored in the container body 10 to be described in detail later to flow into the discharge port member 20 and an inflow valve mechanism 50 to be described in detail later. And an outflow valve mechanism 60 for outflowing the inflowing fluid to the outside.

  In the vicinity of the opening 11 of the container main body 10, a plurality of vent holes 13 are formed for taking outside air into a space formed between the opening 11 of the container main body 10 and the piston member 40. Further, a male screw portion 14 is formed on the outer peripheral portion of the opening of the container main body 10 to be connected to the discharge port member 20 described in detail later.

  FIG. 2 is an explanatory view showing the piston member 40. Among these drawings, FIG. 2 (a) is a longitudinal sectional view of the piston member 40, and FIG. 2 (b) is a front view thereof. FIG. 2C is a bottom view thereof.

  The piston member 40 is formed with a hole 41 through which the tube member 30 is inserted. A convex liquid-tight portion 44 that contacts the cylinder portion 12 of the container body 10 is formed on the upper and lower portions of the outer peripheral surface of the piston member 40. The liquid-tight parts 44 formed at the upper part and the lower part are arranged at positions separated by a certain distance. Further, a convex liquid-tight portion 42 that comes into contact with the tube member 30 is formed in the lower portion inside the hole portion 41 of the piston member 40, and a convex shape that comes into contact with the tube member 30 is formed in the upper portion inside the hole portion 41. The liquid-tight part 43 is formed. The upper liquid-tight portion 43 protrudes from the lower liquid-tight portion 42. For this reason, even if the piston member 40 has a larger elastic restoring force in the direction of the tube member 30 on the lower side, the upper liquid-tight portion 43 and the tube member 30 can be brought into close contact with each other. Thereby, the fluid stored in the space formed between the bottom of the container body 10 and the piston member 40 flows into the space formed between the opening 11 of the container body 10 and the piston member 40. It is possible to prevent this.

  In addition, the liquid-tight parts 42 and 43 and the liquid-tight part 44 formed in the piston member 40 are not limited to those formed in the upper part and the lower part, and may be formed in the middle part. Individual pieces may be formed. Further, the liquid-tight portion 43 and the liquid-tight portion 44 formed on the piston member are not limited to being formed at corresponding positions.

  FIG. 3 is an explanatory view showing the discharge port member 20. Among these drawings, FIG. 3A is a longitudinal sectional view of the discharge port member 20, and FIG. 3B is a left side view thereof.

  The discharge port member 20 is composed of an elastic member having a flow passage 21 for allowing the fluid stored in the container body 10 to flow out. A female screw portion 22 is formed at the end of the flow passage 21 in the discharge port member 20 on the container body 10 side. The female screw portion 22 is screwed with a male screw portion 14 formed outside the opening 11 of the container body 10. Further, a plurality of rib portions 23 are formed at the discharge side end portion of the fluid of the flow passage 21 in the discharge port member 20. The rib portion 23 constitutes a part of the outflow valve mechanism 60, and supports the movement of the valve member 61 described in detail later. Further, a bulging portion 24 is formed between the female screw portion 22 and the rib portion 23 of the flow passage 21 in the discharge port member 20. The bulging portion 24 is formed thin. As a result, the width of the flow passage 21 is reduced by external pressure, and when the external pressure is released, the inside of the flow passage 21 can be decompressed by the elastic restoring force of the discharge port member 20.

  FIG. 4 is an explanatory view showing the valve member 61 constituting the outflow valve mechanism 60. 4A is a longitudinal sectional view of the valve member 61, and FIG. 4B is a left side view thereof. FIG. 4C is a right side view thereof.

  The valve member 61 has a substantially bowl-shaped valve portion 611 whose outer peripheral surface can be in contact with the inner surface of the flow passage 21 in the discharge port member 20, a shaft portion 612 erected from a substantially central portion of the valve portion 611, It is comprised from an elastic member provided with the latching | locking part 613 located in the valve part 611 and the part 612 on the opposite side.

  The valve part 611 is formed thin. For this reason, when a pressing force from the right side to the left side is applied, the outer peripheral surface is reduced and separated from the inner surface of the flow passage 21. On the other hand, when the pressing force from the right side to the left side is released, or when the pressing force is applied from the left side to the right side, the outer peripheral surface is restored or enlarged, and comes into contact with the inner surface of the flow passage 21.

  The shaft portion 612 is formed in a shape that can slide on the rib portion 23 formed in the discharge port member 20. Sliding about the rib portion 23 of the shaft portion 612 is limited by the valve portion 611 and the locking portion 613.

  FIG. 5 is an explanatory view showing the outflow valve mechanism 60. Among these drawings, FIG. 5A shows the closed state of the outflow valve mechanism 60, FIG. 5B shows the opened state, and FIG. 5C shows the state returning from the opened state to the closed state. Show.

  The outflow valve mechanism 60 is configured by the rib portion 23 and the valve member 61 in the discharge port member 20. When the outflow valve mechanism 60 is naturally left, the outer peripheral surface of the valve portion 611 of the valve member 61 contacts the inner surface of the flow passage 21 of the discharge port member 20 as shown in FIG. Closed state. In the closed state, the outflow valve mechanism 60 prohibits the flow of the fluid between the inside and the outside.

  In the outflow valve mechanism 60, when a pressing force is applied from the inside to the outside, the shaft portion 612 of the valve member 61 is limited by the locking portion 613 as shown in FIG. Until the rib portion 23 of the discharge port member 20 moves relative to the outside. And the outer peripheral surface of the valve part 611 in the valve member 61 shrink | contracts, and it spaces apart from the inner surface of the flow path 21. FIG. For this reason, the outflow valve mechanism 60 enables the fluid to flow between the inside and the outside in this open state.

  Then, when the pressing force is released from the inside to the outside, or when the pressing force is applied from the outside to the inside, the outflow valve mechanism 60, as shown in FIG. The outer peripheral part of the valve part 611 in the valve member 61 expands and contacts the inner surface of the flow passage 21. Thereby, the outflow valve mechanism 60 again prohibits the flow of the fluid between the inside and the outside in this state. Then, the shaft portion 612 of the valve member 61 moves inward relative to the rib portion 23 of the discharge port member 20 until the shaft portion 612 is limited by the valve portion 611.

  The valve member 61 constituting the outflow valve mechanism 60 does not have to have the valve portion 611 disposed on the discharge side of the rib portion 23, and the valve portion 611 is disposed on the inner side of the rib portion 23. Also good.

  FIG. 6 is an explanatory view showing the valve seat member 52 constituting the inflow valve mechanism 50. 6A is a longitudinal sectional view of the valve seat member 52, and FIG. 6B is a top view thereof. FIG. 6C is a bottom view thereof.

  The valve seat member 52 is sandwiched between the container main body 10 and the discharge port member 20 to be fixed to the discharge port member 20, a cylindrical inner wall 522, and later described in detail. A plurality of rib portions 523 that slidably support a sliding portion 513 (see FIG. 7) in the valve member 51 to be described, and a coupling portion 524 connected to the upper end portion of the pipe member 30 are provided.

  FIG. 7 is an explanatory view showing the valve member 51 constituting the inflow valve mechanism 50. Among these drawings, FIG. 7A is a longitudinal sectional view of the valve member 51, and FIG. 7B is a top view thereof. FIG. 7C is a bottom view thereof.

  The valve member 51 has a substantially bowl-shaped valve portion 511 whose outer peripheral surface can come into contact with the inner wall 522 of the valve seat member 52, a shaft portion 512 erected from a substantially central portion of the valve portion 511, and a shaft portion 512. And a sliding portion 513 that is slidably supported by the rib portion 523 of the valve seat member 52.

  The valve part 511 is formed thin. For this reason, when a pressing force from the lower side to the upper side is applied, the outer peripheral surface thereof is reduced and separated from the inner wall 522 of the valve seat member 52. On the other hand, when the pressing force from the lower side to the upper side is released, or when the pressing force is applied from the upper side to the lower side, the outer peripheral surface is restored or enlarged, and the inner wall 522 of the valve seat member 52 is Abut.

  The sliding portion 513 is formed in a shape that can slide on the rib portion 523 formed on the valve seat member 52. The sliding of the sliding portion 513 with respect to the rib portion 523 is limited by the lower end and the upper end of the sliding portion 513.

  FIG. 8 is an explanatory view showing the inflow valve mechanism 50. Among these drawings, FIG. 8A shows a closed state of the inflow valve mechanism 50, and FIG. 8B shows an opened state thereof.

  The inflow valve mechanism 50 includes a valve seat member 52 and a valve member 51. When the inflow valve mechanism 50 is naturally left, as shown in FIG. 8A, the inflow valve mechanism 50 is in a closed state in which the outer peripheral surface of the valve portion 511 of the valve member 51 contacts the inner wall 522 of the valve seat member 52. It becomes. The inflow valve mechanism 50 prohibits the flow of the fluid between the inside and the outside of the container body 10 in this closed state.

  In the inflow valve mechanism 50, when a pressing force is applied from the inside of the container body 10 to the outside, the sliding portion 513 in the valve member 51 is limited by its lower end, as shown in FIG. Until it moves relative to the rib portion 523 of the valve seat member 52 toward the outside of the container body 10. Then, the outer peripheral surface of the valve portion 511 in the valve member 51 is reduced and separated from the inner wall 522 of the valve seat member 52. For this reason, the inflow valve mechanism 50 enables the fluid to flow between the inside and the outside of the container body 10 in this open state.

  The outflow valve mechanism 60 is again shown in FIG. 5A when the pressing force is released from the inside of the container body 10 to the outside, or when the pressing force is applied from the outside to the inside. As described above, the outer peripheral portion of the valve portion 511 in the valve member 51 expands and contacts the inner wall 522 of the valve seat member 52. Thereby, the inflow valve mechanism 50 again prohibits the flow of the fluid between the inside and the outside of the container body 10. And until the sliding part 513 in the valve member 51 is restricted by its upper end, it moves in the inner direction of the container body 10 relative to the rib part 523 in the valve seat member 52.

  FIG. 9 thru | or FIG. 11 is a longitudinal cross-sectional view of the fluid storage container which shows the state which discharges the fluid stored in the inside of the container main body 10 in such a fluid storage container.

  When discharging the fluid stored in the container main body 10 in such a fluid storage container, as shown in FIG. 9, the expansion part 24 in the discharge outlet member 20 is pressed. Thereby, the inside of the flow passage 21 in the discharge port member 20 is pressurized. For this reason, the inflow valve mechanism 50 receives a pressing force from the outside to the inside of the container body 10. Further, the outflow valve mechanism 60 receives a pressing force from the inside to the outside. Thereby, the outflow valve mechanism 60 is opened, and the fluid stored between the inflow valve mechanism 50 and the outflow valve mechanism 60 in the discharge port member 20 flows out to the outside.

  When an appropriate amount of fluid has flowed out, as shown in FIG. 10, the pressure on the bulging portion 24 in the discharge port member 20 is released. Thereby, the inside of the flow passage 21 in the discharge port member 20 is decompressed. For this reason, the inflow valve mechanism 50 receives a pressing force from the inside of the container body 10 to the outside. As a result, the inflow valve mechanism 50 is opened, and the fluid formed between the bottom of the container body 10 and the piston member 40 via the flow path 31 of the pipe member 30 is stored in the discharge port member 20. It flows into the flow passage 21. The outflow valve mechanism 60 receives a pressing force from the outside to the inside. Thereby, the outflow valve mechanism 60 moves from the open state to the closed state. At this time, since the inside of the flow passage 21 in the discharge port member 20 is depressurized, the fluid remaining in the vicinity of the outflow valve mechanism 60 can be wound into the flow passage 21 in the discharge port member 20.

  And the fluid stored in the space formed between the bottom part of the container main body 10 and the piston member 40 decreases. For this reason, the piston member 40 moves toward the bottom of the container body 10. Along with this, the space formed between the opening 11 of the container body 10 and the piston member 40 is enlarged. For this reason, outside air flows from the vent hole 13 formed in the container body 10.

  When the above operation is completed and the pressure relation between the members is the same, as shown in FIG. 11, the inflow valve mechanism 50 and the outflow valve mechanism 60 are closed, and the piston member 40 is also moved. It stops and the inflow of outside air from the vent hole 13 is also stopped.

  The fluid storage container according to the first embodiment of the present invention has such a configuration, so that the piston member does not receive the gravity of the fluid unlike the conventional fluid storage container, and the fluid leaks from the piston member. The problem of running down does not occur.

  Next, another embodiment of the present invention will be described with reference to the drawings. In addition, about the member same as 1st Embodiment mentioned above, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

  The discharge port member 200 is composed of an elastic member having a flow passage 201 for allowing the fluid stored in the container body 10 to flow out. A female screw portion 202 is formed at the end of the flow passage 201 of the discharge port member 200 on the container body 10 side. The female screw portion 202 is screwed with the male screw portion 14 formed outside the opening 11 of the container body 10. Further, at the discharge side end portion of the fluid in the flow passage 201 in the discharge port member 200, an engaging portion 203 that engages with a valve seat member 640 constituting an outflow valve mechanism 600 described in detail later is formed. . Further, a bulging portion 204 is formed between the female screw portion 202 and the engaging portion 203 of the flow passage 201 in the discharge port member 200. The bulging portion 204 is formed thin. As a result, the width of the flow passage 201 is reduced by external pressure, and when the external pressure is released, the inside of the flow passage 21 can be decompressed by the elastic restoring force of the discharge port member 20.

  The outflow valve mechanism 600 includes a valve seat member 640 and a valve member 630.

  FIG. 14 is an explanatory view showing a valve seat member 640 constituting the outflow valve mechanism 600. 14A is a longitudinal sectional view of the valve seat member 640, and FIG. 14B is a left side view thereof. FIG. 14C is a right side view thereof.

  The valve seat member 640 has a hole 641 formed in a shape corresponding to the valve portion 631 of the valve member 630, which will be described in detail later, and a hollow cylindrical engagement for engaging with the support portion 634 of the valve member 630. A portion 642 and a convex portion 643 for coupling to the engaging portion 203 of the discharge port member 200.

  FIG. 15 is an explanatory view showing the valve member 630 constituting the outflow valve mechanism 600. Among these drawings, FIG. 15 (a) is a longitudinal sectional view of the valve member 630, and FIG. 15 (b) is a left-side immediate sectional view thereof. FIG. 15C is a right side view thereof.

  The valve member 630 includes a valve portion 631 that can come into contact with the outer shape of the hole 641 of the valve seat member 640, a support portion 634 that engages with the engagement portion 642 of the valve seat member 640, and the valve portion 631 and the support portion 634. And four connecting portions 632 for connecting the two. Each of the four connecting portions 632 has a pair of bent portions 633, thereby having suitable elasticity and flexibility.

  As described above, the outflow valve mechanism 600 includes the valve seat member 640 and the valve member 630. When the spill valve mechanism 600 is naturally left, as shown in FIG. 16A, the valve portion 631 in the valve member 630 is in a closed state in which the valve portion 631 contacts the outer shape of the hole portion 641 in the valve seat member 640. It becomes. In the closed state, the outflow valve mechanism 600 prohibits the flow of the fluid between the inside and the outside.

  In this outflow valve mechanism 600, when a pressing force is applied from the inside to the outside, the valve portion 631 in the valve member 630 is restricted by the connecting portion 632 as shown in FIG. The valve seat member 640 is separated from the hole 641. For this reason, the outflow valve mechanism 600 enables the fluid to flow between the inside and the outside in this open state.

  When the pressing force is released from the inside to the outside, or when the pressing force is applied from the outside to the inside, the outflow valve mechanism 600, as shown in FIG. Due to the elasticity or flexibility of the connecting portion 632 in the valve member 630, the valve portion 631 contacts the outer shape of the hole portion 641 in the valve seat member 640. Thereby, the outflow valve mechanism 600 again prohibits the flow of the fluid between the inside and the outside in this state.

  Note that the valve seat member 640 and the discharge port member 200 constituting the outflow valve mechanism 600 may be configured as an integral member. In this case, since the number of components can be reduced, it is possible to reduce manufacturing costs and manufacturing steps.

Are provided with four connecting portions 532. Each of the four connecting portions 532 has a pair of bent portions 533 and thus has suitable elasticity and flexibility.

  FIG. 19 is an explanatory view showing the inflow valve mechanism 500. Among these drawings, FIG. 19A shows a closed state of the inflow valve mechanism 500, and FIG. 19B shows an opened state thereof.

  The inflow valve mechanism 500 includes a valve seat member 540 and a valve member 530. When the inflow valve mechanism 500 is naturally left, as shown in FIG. 19A, the inflow valve mechanism 500 is in a closed state in which the valve portion 531 in the valve member 530 contacts the outer shape of the hole portion 541 in the valve seat member 540. It becomes. The inflow valve mechanism 500 prohibits the flow of the fluid between the inside and the outside in the closed state.

  In the inflow valve mechanism 500, when a pressing force is applied from the inside to the outside, the valve portion 531 in the valve member 530 is limited by the connecting portion 532 as shown in FIG. The valve seat member 540 is separated from the hole 541. For this reason, the inflow valve mechanism 500 enables the fluid to flow between the inside and the outside in this open state.

  When the pressing force is released from the inside to the outside, or when the pressing force is applied from the outside to the inside, the inflow valve mechanism 500 is again as shown in FIG. The valve portion 531 comes into contact with the outer shape of the hole 541 in the valve seat member 540 due to the elasticity or flexibility of the connecting portion 532 in the valve member 530. Thereby, the inflow valve mechanism 500 again prohibits the flow of the fluid between the inside and the outside in this state.

  In the fluid storage container according to the second embodiment, when the fluid stored in the container body 10 is discharged, the discharge is performed in the same manner as in the fluid storage container according to the first embodiment. The bulging part 204 in the outlet member 200 is pressed. Thereby, the fluid stored between the inflow valve mechanism 500 and the outflow valve mechanism 600 in the discharge port member 200 flows out to the outside. When an appropriate amount of fluid has flowed out, the pressure on the expansion portion 204 in the discharge port member 200 is released. Thereby, the inflow valve mechanism 500 is opened, and the fluid formed between the bottom of the container body 10 and the piston member 40 via the flow path 31 of the pipe member 30 is stored in the space in the discharge port member 200. It flows into the flow path 201.

  Further, the outflow valve mechanism 600 receives a pressing force from the outside to the inside. Thereby, the outflow valve mechanism 60 moves from the open state to the closed state. At this time, since the inside of the flow passage 201 in the discharge port member 200 is depressurized, the fluid remaining in the vicinity of the outflow valve mechanism 600 can be wound into the flow passage 201 in the discharge port member 200. And the fluid stored in the space formed between the bottom part of the container main body 10 and the piston member 40 decreases. For this reason, the piston member 40 moves toward the bottom of the container body 10. Along with this, the space formed between the opening 11 of the container body 10 and the piston member 40 is enlarged. For this reason, outside air flows from the vent hole 13 formed in the container body 10.

  In the fluid storage container according to the second embodiment of the present invention, the piston member does not receive the gravity of the fluid as in the conventional fluid storage container as in the fluid storage container according to the first embodiment. There is no problem that the fluid leaks from the piston member and flows down.

  In addition, the structure which is not provided with the inflow valve mechanism 50 and 500 in the fluid storage container which concerns on 1st Embodiment mentioned above and 2nd Embodiment may be sufficient as a fluid storage container. In this case, the expansion part 24 in this fluid storage container is pressed. Thereby, the inside of the flow passage 21 in the discharge port member 20, the inside of the flow path 31 in the pipe member 30, and the inside of the space between the bottom of the container body 10 and the piston member 40 are pressurized. For this reason, the outflow valve mechanism 60 or the outflow valve mechanism 600 receives a pressing force from the inside to the outside. Thereby, the outflow valve mechanism 60 or the outflow valve mechanism 600 is opened, and the fluid stored in the flow passage 21 of the discharge port member 20 flows out to the outside.

  Thereafter, when an appropriate amount of fluid has flowed out, the pressure on the expansion portion 24 in the fluid storage container is released. Thereby, the inside of the flow passage 21 in the discharge port member 20, the inside of the flow path 31 in the pipe member 30, and the inside of the space between the bottom of the container body 10 and the piston member 40 are decompressed. For this reason, the outflow valve mechanism 60 or the outflow valve mechanism 600 receives a pressing force from the outside to the inside. Thereby, the outflow valve mechanism 60 or the outflow valve mechanism 600 moves from the open state to the closed state. At this time, since the inside of the flow passage 21 in the discharge port member 20 is depressurized, the fluid remaining in the vicinity of the outflow valve mechanism 60 or the outflow valve mechanism 600 can be caught in the flow passage 21 in the discharge port member 20. Become.

  Further, since the inside of the flow passage 21 in the discharge port member 20 is depressurized, the piston member 40 moves toward the bottom of the container body 10. Along with this, the space formed between the opening 11 of the container body 10 and the piston member 40 is enlarged. For this reason, outside air flows from the vent hole 13 formed in the container body 10. When the above operation is completed and the pressure relation between the members is the same, the outflow valve mechanism 60 or the outflow valve mechanism 600 is again closed, the movement of the piston member 40 is stopped, and the vent hole 13 is stopped. Inflow of outside air from the air also stops.

  FIG. 20 is a longitudinal sectional view showing a fluid storage container according to the third embodiment of the present invention.

  The fluid storage container according to the third embodiment of the present invention is a fluid instead of the discharge port member 20, the inflow valve mechanism 50, and the outflow valve mechanism 60 constituting the fluid storage container according to the first embodiment. The fluid storage container according to the first embodiment is different from the fluid storage container according to the first embodiment in that a discharge pump 700, a nozzle head 800, and an outer lid 810 are provided.

  The fluid discharge pump 700 constituting the fluid storage container according to the third embodiment is disposed inside the opening 11 of the container body 10. This fluid discharge pump 700 has a nozzle head connected by connecting a cylinder 723 whose lower end opening is connected to the pipe member 30, a piston 783 capable of reciprocating inside the cylinder 723, a nozzle head 800 and a piston 783. The first and second connecting cylinders 781 and 782 that are connected and fixed to each other to constitute a connecting cylinder for lowering the piston 783 by transmitting the pressing force applied to the piston 783 and the piston 783 is raised. The coil spring 724 disposed on the outer periphery of the first and second connecting cylinders 781 and 782 for energizing in the direction to be moved, and the fluid stored in the container main body 10 are lifted by the piston 783 via the pipe member 30. An inflow valve mechanism 750 for flowing into the cylinder 723 in accordance with the operation, and a fluid flowing into the cylinder 723 into the piston 7 3, an intermediate valve mechanism 760 for opening and closing an opening 791 for flowing into the first and second connecting cylinders 781 and 782, and the inside of the first and second connecting cylinders 781 and 782. And an outflow valve mechanism 770 for flowing out the fluid flowing into the nozzle head 800 to the discharge port of the nozzle head 800.

  The inflow valve mechanism 750 includes a lower end opening formed at the lower end portion of the cylinder 723, a valve portion formed in a shape corresponding to the lower end opening portion of the cylinder 723, a support portion engaged with the cylinder 723, a valve portion And a resin valve member 751 having four connecting portions having elasticity and flexibility for connecting the support portion and the support portion. For this reason, when the inside of the cylinder 723 is pressurized, the inflow valve mechanism 750 closes the lower end opening of the cylinder 723 by contacting the lower end opening of the cylinder 723 due to the elasticity or flexibility of the connecting portion. At the same time, when the inside of the cylinder 723 is depressurized, the valve portion is separated from the lower end opening of the cylinder 723 by the elasticity or flexibility of the connecting portion to open the lower end opening of the cylinder 723.

  The intermediate valve mechanism 760 includes a piston 783 and a second connecting cylinder 782. The piston 783 is disposed on the second connecting cylinder 782 so as to be slidable between a joint portion of the second connecting cylinder 782 with the first connecting cylinder 78 and a lower end portion of the second connecting cylinder 782. The For this reason, the intermediate valve mechanism 760 is configured such that when the inside of the space between the lower end opening of the cylinder 723 and the piston 783 is pressurized, the upper end of the piston 783 is the first connection cylinder 781 in the second connection cylinder 782. When the inside of the space between the lower end opening of the cylinder 723 and the piston 783 is depressurized, the lower end of the piston 783 is moved to the second position. The opening 791 is closed by moving to a position in contact with the lower end of the connecting cylinder 782.

  The outflow valve mechanism 770 includes an upper end opening of the first connection cylinder 782, a bowl-shaped valve formed in a shape corresponding to the upper end opening of the first connection stopper 782, and a plurality of erected valve units. And a resin valve member 771 having a support portion. For this reason, when the inside of the first and second connection cylinders 781 and 782 is pressurized, the outflow valve mechanism 770 reduces the maximum planar area of the bowl-shaped valve portion, and the upper end opening of the first connection cylinder 782 When the interiors of the first and second connecting cylinders 781 and 782 are depressurized, the maximum planar area of the bowl-shaped valve portion is enlarged and the upper end opening of the first connecting cylinder 782 is closed.

  21 to 23 show a state of the fluid discharge pump 700 showing a state in which the fluid stored in the container body 10 is discharged in the fluid discharge pump 700 constituting the fluid storage container according to the third embodiment. It is a longitudinal cross-sectional view.

  When the fluid discharge pump 700 is left in a natural state, all of the inflow valve mechanism 750, the intermediate valve mechanism 760, and the outflow valve mechanism 770 are closed as shown in FIG. Yes.

  In the case of discharging a fluid from the fluid discharge pump 700, first, a pressing force is applied to the nozzle head 800 as shown in FIG. When a pressing force is applied to the nozzle head 800, the nozzle head 800 is lowered against the biasing force of the coil spring 824. At this time, the piston 783 descends as the nozzle head 800 descends. When the piston 783 descends in this way, the inside of the space between the lower end opening of the cylinder 723 and the piston 783 is pressurized. When the inside of the space formed between the lower end opening of the cylinder 723 and the piston 783 is pressurized, the upper end of the piston 783 is joined to the first connection cylinder 781 in the second connection cylinder 782 in the intermediate valve mechanism 760. The opening 791 is opened by moving to a position in contact with the portion. Thereby, the fluid stored in the space formed between the lower end opening of the cylinder 823 and the piston 783 flows into the first and second connecting cylinders 781 and 782. When the fluid flows into the first and second connecting cylinders 781 and 782 as described above, the insides of the first and second connecting cylinders 781 and 782 are pressurized. When the insides of the first and second connecting cylinders 781 and 782 are pressurized, the maximum planar area of the bowl-shaped valve portion is reduced in the outflow valve mechanism 770 and the upper end opening of the first connecting cylinder 782 is opened. Then, the fluid flowing into the first and second connecting cylinders 781 and 782 flows out to the discharge port of the nozzle head.

  Next, when the pressing force to the nozzle head 800 is released, the nozzle head 800 is raised by the elastic restoring force of the coil spring 724 as shown in FIG. At this time, the piston 783 rises as the nozzle head 800 moves up. When the piston 783 rises in this way, the inside of the space between the lower end opening of the cylinder 723 and the piston 783 is depressurized. When the inside of the space between the lower end opening of the cylinder 723 and the piston 783 is depressurized, the lower end of the piston 783 moves to a position in contact with the lower end of the second connecting cylinder 782 in the intermediate valve mechanism 760 to open the opening. The part 791 is closed. Thereby, the insides of the first and second connecting cylinders 781 and 782 are not pressurized. When the insides of the first and second connecting cylinders 781 and 782 are no longer pressurized, the maximum planar area of the bowl-shaped valve portion is increased in the outflow valve mechanism 770 and the upper end opening of the first connecting cylinder 782 is closed. Further, when the inside of the space between the lower end opening of the cylinder 723 and the piston 783 is depressurized, the valve portion is separated from the lower end opening of the cylinder 723 by the elasticity or flexibility of the connecting portion in the inflow valve mechanism 750. Then, the lower end opening of the cylinder 723 is opened. Then, the fluid stored in the container main body 10 flows into the cylinder 723 through the pipe member 30.

  FIGS. 24 to 26 are longitudinal sectional views of the fluid storage container showing a state in which the fluid stored in the container body 10 is discharged in the fluid storage container according to the third embodiment.

  When the fluid stored in the container body 10 is discharged in the fluid storage container according to the third embodiment, a pressing force is applied to the nozzle head 800 as shown in FIG. As a result, the outflow valve mechanism 770 in the fluid discharge pump 800 is opened, and the fluid flows out from the discharge port of the nozzle head 800.

  When an appropriate amount of fluid has flowed out, the pressing force to the nozzle head 800 is released as shown in FIG. When the pressing force to the nozzle head 800 is released, the outflow valve mechanism 770 is closed and the inflow valve mechanism 750 is opened, and the space inside the space between the bottom of the container body 10 and the piston member 40 is opened. The fluid stored in the fluid flows into the cylinder 723 through the pipe member 30. Thereby, the inside of the flow path 31 in the pipe member 30 and the inside of the space formed between the bottom of the container body 10 and the piston member 40 are decompressed. For this reason, the piston member 40 moves toward the bottom of the container body 10.

  When the piston member 40 moves toward the bottom of the container body 10, the space formed between the opening 11 of the container body 10 and the piston member 40 is expanded as shown in FIG. As a result, outside air flows from the vent hole 13 formed in the container body 10.

  When the above operation is completed and the pressure relation between the members is the same, as shown in FIG. 22, the inflow valve mechanism 750 is closed again, and the movement of the piston member 40 is also stopped. The inflow of outside air from the pores 13 is also stopped.

  The fluid storage container according to the third embodiment of the present invention has such a configuration, so that the piston member does not receive the gravity of the fluid unlike the conventional fluid storage container, and the fluid leaks from the piston member. The problem of running down does not occur.

  FIG. 27 is a longitudinal sectional view showing a fluid storage container according to the fourth embodiment of the present invention.

  The fluid storage container according to the fourth embodiment of the present invention is the third embodiment in that a fluid discharge pump 900 is provided instead of the fluid discharge pump 700 constituting the fluid storage container according to the third embodiment. It is different from the fluid storage container according to the form.

  The fluid discharge pump 900 constituting the fluid storage container according to the fourth embodiment is replaced with the cylinder 723 and the inflow valve mechanism 750 in the fluid discharge pump 700 constituting the fluid storage container according to the third embodiment. A cylinder 923 and an outflow valve mechanism 950. A plurality of ribs are formed near the lower end opening of the cylinder 923.

  The outflow valve mechanism 950 includes a rib portion and a lower end opening formed in the cylinder 923, and a valve member 951.

  The valve member 951 has a substantially bowl-shaped valve portion whose outer peripheral surface can come into contact with the lower end opening of the cylinder 923, a shaft portion erected from a substantially central portion of the valve portion, and a substantially central portion of the shaft portion. And an elastic member provided with a sliding portion that is slidably supported by the rib portion of the cylinder 923.

  The valve part in the valve member 951 is formed thin. For this reason, when a pressing force is applied from below to above, the outer peripheral surface is reduced and separated from the lower end opening of the cylinder 923. On the other hand, when the pressing force from the lower side to the upper side is released, or when the pressing force is applied from the upper side to the lower side, the outer peripheral surface is restored or enlarged so as to hit the lower end opening of the cylinder 923. Touch.

  The sliding portion is formed in a shape that can slide on the rib portion formed on the cylinder 923. The sliding of the sliding portion with respect to the rib portion is limited by the lower end and the upper end of the sliding portion.

  In the fluid storage container according to the fourth embodiment, when the fluid stored in the container body 10 is discharged, the nozzle head is used in the same manner as in the fluid storage container according to the third embodiment. A pressing force is applied to 800. Thereby, the outflow valve mechanism 770 in the fluid discharge pump 900 is opened, and the fluid flows out from the discharge port of the nozzle head 800.

  When the pressing force to the nozzle head 800 is released, the outflow valve mechanism 770 is closed and the inflow valve mechanism 950 is opened, and is placed between the bottom of the container body 10 and the piston member 40. A fluid stored in the space flows into the cylinder 923 through the pipe member 30. Thereby, the inside of the flow path 31 in the pipe member 30 and the inside of the space formed between the bottom of the container body 10 and the piston member 40 are decompressed. For this reason, the piston member 40 moves toward the bottom of the container body 10.

  When the piston member 40 moves toward the bottom of the container body 10, the space formed between the opening 11 of the container body 10 and the piston member 40 is expanded. As a result, outside air flows from the vent hole 13 formed in the container body 10.

  When the above operation is completed and the pressure relation between the members is the same, the inflow valve mechanism 750 is closed again, the movement of the piston member 40 is stopped, and the inflow of outside air from the vent hole 13 is performed. Also stop.

  The fluid storage container according to the fourth embodiment of the present invention has such a configuration, so that the piston member does not receive the gravity of the fluid unlike the conventional fluid storage container, and the fluid leaks from the piston member. The problem of running down does not occur.

  In the embodiment described above, the piston member 40 is provided, but the piston member 70 may be provided instead of the piston member 40.

  FIG. 28 is an explanatory view showing the piston member 70. Of these drawings, FIG. 28 (a) is a longitudinal sectional view of the piston member 70, and FIG. 28 (b) is a top view thereof. FIG. 28C is a bottom view thereof.

  Similar to the piston member 40, the piston member 70 has a hole 71 through which the tube member 30 is inserted. A convex liquid-tight portion 74 that contacts the cylinder portion 12 of the container body 10 is formed on the upper and lower portions of the outer peripheral surface of the piston member 70. In addition, a convex liquid-tight portion 72 that comes into contact with the tube member 30 is formed in the lower portion inside the hole portion 71 of the piston member 70, and a convex shape that comes into contact with the tube member 30 in the upper portion inside the hole portion 71. The liquid-tight part 73 is formed. The upper liquid-tight part 73 protrudes from the lower liquid-tight part 72.

  The piston member 70 is composed of an elastic member in which two bent portions 75 concentric with the outer periphery are formed on a plane perpendicular to the moving direction of the container body 10 in the cylinder portion 12.

  Therefore, according to the piston member 70, even if the bent portion 75 has an urging force in the outer circumferential direction and the shape of the cylinder portion 12 of the container body 10 changes, the cylinder corresponds to the change. It becomes possible to contact the wall surface of the portion 12 in a liquid-tight manner.

  In the above-described embodiment, the fluid between the bottom of the container body 10 and the bottom surfaces of the piston members 40 and 70 is made to correspond to the inclination of the bottom of the container body 10 and the bottom surfaces of the piston members 40 and 70. It is possible to reduce the residual amount of.

  FIG. 29 is an explanatory view showing the bottom of the container body 10 when the bottom part of the container body 10 and the bottom surface of the piston member 70 are inclined.

  The container body 10 shown in FIG. 29 has a substantially hemispherical bottom. By forming the bottom part in a substantially hemispherical shape in this way, the fluid collects and remains in the central part. In this case, the container main body 10 and the piston member 70 are formed by forming the lower end of the hole portion 71 of the piston member 70, the bent portion 75, and the lower liquid-tight portion 74 into a shape that can be brought into contact with the bottom of the container main body 10 simultaneously. It is possible to reduce the residual amount of fluid between the two.

  FIG. 30 is an explanatory view showing a state in which the container main body 100 is filled with the fluid in the fluid storage container according to the fifth embodiment of the present invention.

  The container main body 100 in this fluid storage container includes a bottomed cylindrical container lower part 110 and a container upper part 120 that can be coupled to the upper end part 111 of the container lower part 110. For this reason, it becomes possible to remove the container upper part 120 and the piston member 40 from the container lower part 110 and to easily fill the fluid.

  In the vicinity of the opening 121 of the container upper part 120, a plurality of vent holes 123 for taking outside air into a space formed between the opening 121 of the container main body 100 and the piston member 40 are formed. Further, a male screw portion 124 for coupling to the fluid discharge pump 900 is formed on the outer peripheral portion of the opening 121.

  The container lower part 110 has an end part 111 for coupling with the container upper part 120 and a cylinder part 112 for sliding the piston member 40. A plurality of notches 113 are formed on the inner side of the end 111. For this reason, as shown in FIG. 30, when the fluid is filled in the container lower part 110 and the piston member 40 is attached, the air that has entered the space between the fluid filled in the container lower part 110 and the piston member 40 is removed. It becomes possible to flow out of the container lower part 110 through the notch 113.

  In the fifth embodiment, a plurality of notches 113 are formed in the container lower part 110, but the entire peripheral surface may be inclined from the end 111 to the cylinder 112.

  In addition, the above-described combination of the container main bodies 10 and 100, the discharge port members 20 and 200, the inflow valve mechanisms 50 and 500, and the outflow valve mechanisms 60 and 600, or the fluid discharge pumps 700 and 900, and the piston member 40. , 70 can be selected and combined.

  FIG. 31 is an explanatory view showing a fluid storage container in which the container body 100 and the piston member 70 are selected and combined.

  According to the fluid storage container shown in FIG. 31, even when the shape of the cylinder part 112 of the container main body 100 changes, it is possible to contact the wall surface of the cylinder part 112 in a liquid-tight manner in response to the change. In addition, when the fluid is filled in the container lower part 110 and the piston member 70 is attached, the air that has entered between the fluid filled in the container lower part 110 and the piston member 70 passes through the inclined surface of the end 111. It becomes possible to flow out of the container lower part 110.
