EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described based on drawing.

Fig. 1 is a longitudinal sectional schematic view of a fluid container to which the fluid discharge pump 1 according to the first embodiment of the present invention is applied.

This fluid container is used as a gel such as a hair gel and a cleansing gel commonly used in the cosmetic field, or a cream container such as a nourishing cream or a massage cream. In addition, in this specification, it is called a fluid, including the gel, cream, etc. which a normal liquid, high viscosity liquid, a semi-fluid body, or a sol solidified to the jelly state.

This fluid container is composed of a fluid discharge pump 1 according to the present invention, a nozzle head 2, a lid 3, and a fluid reservoir 4 containing a fluid in the interior thereof. Here, the nozzle head 2 is connected to the discharge part 41 for discharging a fluid, the press part 42 pressed at the time of discharge of a fluid, and the press part 42 through the cylindrical shape 13. When the press part 42 receives a pressure, it transmits this pressure to the piston 12, and has the hollow connecting cylinder 43 for lowering the piston 12. As shown in FIG.

The nozzle head 2 is detachable from the fluid discharge pump 1. Further, the fluid reservoir 4 has a cylindrical cylinder member 5 and a piston member 6 for moving the cylinder member 5 in the up and down direction.

The fluid discharge pump 1 and the fluid reservoir 4 are connected in a liquid-tight state through the packing 44.

In this fluid container, the pressurizing portion 42 in the nozzle head 2 is pressed to reciprocate in the vertical direction, and the fluid reservoir 4 is operated by the action of the fluid discharge pump 1 to be described in detail later. The fluid stored therein is discharged from the discharge portion 41 in the nozzle head 2. As the fluid in the fluid reservoir 4 decreases, the piston member 6 moves in the cylinder member 5 in the direction of the nozzle head 2, as shown in FIG.

In this manual, the vertical direction in Figs. 1 and 2 is defined as the vertical direction of the fluid container. That is, in the fluid container which concerns on this embodiment, the nozzle head 2 side shown in FIG. 1 is made upward, and the piston member 6 side is made downward.

Next, the structure of the fluid discharge pump 1 which concerns on this invention is demonstrated. 3 and 4 are longitudinal sectional views showing the fluid discharge pump 1 according to the first embodiment of the present invention together with the nozzle head 2. In addition, FIG. 3 shows the state in which the connecting cylinder 43 is lowered by the pressing part 42 of the nozzle head 2 being pressed, and FIG. 4 shows that the nozzle head 2 is opened. The connecting cylinder 43 has shown the state which is raising.

This fluid discharge pump 1 is provided with the cylinder 11, the piston 12 which can reciprocate in this cylinder 11, and the cylinder 13 which reciprocates in synchronization with this piston 12. As shown in FIG. .

A spring 15 is disposed between the support member 14 provided below the cylinder 11 and the lower surface of the piston 12. For this reason, when the press part 42 of the nozzle head 2 is pressed, this pressure is transmitted to the piston 12 via the cylinder 13 and the connection cylinder 43, and the piston 12 is The cylinder 11 is lowered in resistance to the spring force caused by the spring 15. On the other hand, when the pressing force with respect to the nozzle head 2 is opened, the piston 12 raises the inside of the cylinder 11 by the action of the spring 15. As shown in FIG.

Below the cylinder 11, the resin-shaped valve 21 is arrange | positioned. A spring 22 is disposed between the valve 21 and the support member 14. The valve 21 is pushed into the opening 16 formed at the lower end of the cylinder 11 by the action of the spring 22.

The toilet seat comprised by these valve 21, the spring 22, and the opening part 16 is comprised by the inflow toilet mechanism.

Inside the cylinder 13, there are disposed valves 31 and 32 which are made of resin, and springs 33 which push the valves 31 and 32 in a direction away from each other. have.

The valve 31 is abutted from above the toilet seat formed on the upper portion of the tub 13 formed in the deg portion of the tub 13 by the action of the spring 33. Moreover, the valve 32 abuts below the toilet seat formed in the lower part of the cylinder shape 13 comprised in the upper end of the connection cylinder by the action of the spring 33. As shown in FIG.

These valves 31 and 32, the spring 33, and each toilet seat constitute an outflow valve mechanism. In particular, the valve 31 constitutes an inflow valve, and the valve 32 constitutes a reverse rise.

In addition, the spring 15, 22, 33 mentioned above is used resinous like the valves 21, 31, 32. The use of resins for these springs 15, 22, 33 and the valves 21, 31, 32 prevents corrosion due to the fluid and disposes the fluid discharge pump 1 This is to avoid adversely affecting the environment.

In this fluid container, the pressurizing portion 42 in the nozzle head 2 is pressed to reciprocate in the vertical direction, and the fluid reservoir 4 is operated by the action of the fluid discharge pump 1 to be described in detail later. The fluid stored therein is discharged from the discharge portion 41 in the nozzle head 2. Then, as shown in Fig. 2, the piston member 6 moves inside the cylinder member 5 in the direction of the nozzle head 2, as the decrease in the fluid reservoir 4 decreases.

In the nozzle head 2 described above, the valve 32 is pressed during the lowering operation of the piston 12 so that the valve 32 is spaced apart from the toilet seat formed above the tub 13. Projection portion 73 is a function of the pressing means for is formed.

Moreover, between the outer peripheral part of the cylindrical shape 13 and the inner peripheral part of the nozzle head 2, the fluid which flowed in the cylinder 11 flows out to the area | regions other than the discharge part 41 in the nozzle head 2, In order to prevent that, the packing 51 made of rings is disposed.

Next, the operation of discharging the fluid due to the fluid discharge container in which the fluid discharge pump 1 has been described will be described.

In the initial state, as shown in Fig. 1, the valve 21 is formed on the toilet seat formed by the opening 16 formed at the lower end of the cylinder 11, and the valve 31 is formed on the toilet seat formed at the bottom of the tubular shape 13, Moreover, the valve 32 is in contact with the toilet seat formed in the upper part of the cylinder 13, respectively. In addition, the cylinder 11 is filled with a fluid.

When the press part 42 in the nozzle head 2 is pressed in this state, the protrusion part 73 formed in the nozzle head 2 presses the valve 32, as shown in FIG. As a result, the valve 32 is spaced apart from the toilet seat formed in the upper portion of the barrel 13 in response to the spring force due to the spring 33.

The pressure applied to the nozzle head 2 is transmitted to the piston 12 via the cylinder 13 and the connecting cylinder 43. As a result, the piston 12 descends the inside of the cylinder 11 together with the cylinder 13 and the connecting cylinder 43. As the piston 12 descends, the valve 31 is pressed by the pressure of the fluid filled in the cylinder 11. For this reason, as shown in FIG. 3, the valve 31 is spaced apart from the toilet seat formed in the lower part of the cylindrical shape 13 against the repulsion force by the spring 33, and a fluid flows into the cylindrical shape 13 do.

The fluid flowing into the cylinder 13 passes through the interior of the connecting cylinder 43 and the interior of the cylinder 13, and then is discharged from the discharge portion 41 of the nozzle head 2.

Then, the piston 12 stops after descending to the lower end of the stroke together with the nozzle head 2. Here, a plurality of spacers 81 are disposed inside the lid 3. The piston 12 stops at the position where the lower end of the nozzle head 2 abuts on the surface of the spacer 81. That is, the spacer 81 can determine the position of the lower end of the stroke 12, that is, the reciprocating stroke of the piston 12. For this reason, by adjusting the number or thickness of the spacers 81, the discharge amount of the fluid can be accurately adjusted.

If the pressure applied to the nozzle head 2 is released after the piston 12 is lowered to the lower end of the stroke, as shown in Fig. 4, the valve 32 is caused by the repulsive force of the spring 33 and the spring 72; Presses up the projection 73 formed inside the nozzle head 2. As a result, the valve 32 abuts on the toilet seat formed in the upper portion of the tub 13.

Moreover, by the action of the spring 15, the piston 12 raises the inside of the cylinder 11 with the connecting cylinder 43 and the cylinder 13. As shown in FIG. With the rise of this piston 12 and the depressurization in the cylinder 11, the valve 21 is pressurized due to the fluid stored in the fluid reservoir 4 shown in FIG. For this reason, as shown in FIG. 4, the valve 21 is spaced apart from the toilet seat which consists of the opening part 16 formed in the lower end of the cylinder 11, against the repulsion force by the spring 22, and in the cylinder 11 is shown. The fluid flows in the fluid reservoir 4.

On the other hand, the valve 31 abuts on the toilet seat formed in the lower part of the tubular shape 13 as shown in FIG. 4 by the elastic force due to the spring 33. For this reason, the fluid in the cylinder 13 and the connection cylinder 43 is not attracted to the cylinder 11 side.

Here, the valve 31 is forcibly brought into contact with the toilet seat formed in the lower part of the cylindrical shape 13 by the action of the spring 33. Therefore, even when a high clay liquid, a gel, or the like is used as the fluid, it is possible to reliably abut the toilet seat formed at the lower portion of the valve 31 and the tub 13, and the tub 13 ) And the fluid in the connecting cylinder 43 can be effectively prevented from being attracted to the cylinder 11 side.

When the piston 12 moves to the upper end of the stroke, the valve 21 abuts on the toilet seat composed of the opening 16 formed at the lower end of the cylinder 11 by the action of the spring 22. In this state, as shown in FIG. 1, the valve 31 is the toilet seat formed in the lower part of the cylinder 13, and the valve 32 is the initial position which contacted the toilet seat formed in the upper part of the cylinder 13, respectively. In this state, the fluid is filled in the cylinder 11.

Here, the valve 21 is forcibly contacted with the toilet seat which consists of the opening part 16 formed in the lower end of the cylinder 11 by the action of the spring 22. As shown in FIG. Therefore, even when a high clay liquid, a gel or the like is used as the fluid, the toilet seat composed of the valve 21 and the opening 16 formed at the lower end of the cylinder 11 can be reliably brought into contact with the cylinder ( It is possible to effectively prevent the fluid in 11 from leaking into the fluid reservoir 4 through the opening 16.

As described above, in the initial state shown in FIG. 1, the valve 21 is a toilet seat formed of an opening 16 formed at the lower end of the cylinder 11, and the valve 31 is a toilet seat formed below the tub 13. In addition, the valve 32 abuts on the toilet seat formed in the upper part of the cylinder 13, respectively.

For this reason, even when the cylinder member 5 of the fluid storage part 4 in this initial state is pressed upward and the pressure is applied to the fluid stored in the fluid storage part 4, the valve 32 will be kept. Since it is in contact with the toilet seat formed in the upper part of the cylindrical shape 13, it becomes possible to reliably prevent the fluid from being discharged from the nozzle head 2.

Further, even if the cylinder member 5 in the fluid reservoir 4 is pressed upward in the state where the nozzle head 2 is pressed, the pressure is applied to the fluid stored in the fluid reservoir 4, The valve 21 is formed on the toilet seat of the opening 16 formed at the lower end of the cylinder 11 by the action of the spring 22, and the valve 31 is the lower part of the tubular shape 13 by the action of the spring 33. Since each of the toilet seats is forcibly brought into contact with the toilet seat, the fluid in the fluid reservoir 4 does not easily reach the nozzle head 2, and the fluid can be effectively prevented from being discharged from the nozzle head 2.

In addition, in the fluid discharge pump 1 mentioned above, the fluid which flowed in the cylinder 11 discharged in the nozzle head 2 between the outer peripheral part of the cylindrical shape 13 and the inner peripheral part of the nozzle head 2 is discharged. Since the packing 51 which becomes a ring for preventing outflow to the area | region other than the part 41 is arrange | positioned, the omission of a fluid can be reliably prevented.

Moreover, in the fluid discharge pump 1 which concerns on this embodiment, the fluid which exists in the area | region below in the cylinder 13 is interrupted | blocked by the action | action of the valve 31 which functions as a reverse rise. This can reliably prevent oxidation and contamination of the fluid.

In addition, since the barrel 13 including the valve 31 constituting the reverse rise is disposed inside the nozzle head 2, it is possible to minimize the amount of the fluid remaining in the nozzle head 2. do.

In addition, since the nozzle head 2 is detachable from the fluid discharge pump 1, the inside of the nozzle head 2 can be easily cleaned. At this time, since the upper part of the cylindrical shape 13 is closed by the valve 31, a fluid is not contaminated inside.

In the above-mentioned embodiment, the air of the fluid discharge pump 1 which concerns on this invention consists of a cylindrical cylinder member 5 and the piston member 6 which moves up and down in this cylinder member 5 inside. Although the case where the fluid container which has the fluid bottle storage part 4 of the response type was applied was demonstrated, it is also possible to apply the fluid discharge pump 1 which concerns on this design to other fluid container.

Fig. 5 is a vertical cross-sectional view showing another embodiment of the fluid container to which the fluid discharge pump 1 according to the first embodiment of the present invention is applied.

Also in this embodiment, the same effects as in the above-described embodiment are achieved.

In particular, in the case of this embodiment, even when the fluid reservoir 8 made of a soft tube in the initial state is pressed and a pressure is applied to the fluid stored in the fluid reservoir 8, the fluid discharge pump Since the valve 32 in (1) is in contact with the toilet seat formed in the upper part of the barrel 13, it can reliably prevent the fluid from being discharged from the nozzle head 2.

In addition, in the case of this embodiment, even if the fluid reservoir 8 made of a soft tube is pressed while the nozzle head 2 is depressed, pressure is applied to the fluid stored in the fluid reservoir 8. In addition, the valve 21 is formed by the action of the spring 22 to the toilet seat formed at the lower end of the cylinder 11, and the valve 31 is formed by the action of the spring 33 to form the tubular 13. Since each of the toilet seats formed in the lower portion is forcibly brought into contact with each other, the fluid in the fluid reservoir 4 cannot easily reach the nozzle head 2, and it is possible to effectively prevent the fluid from being discharged from the nozzle head 2. Done.

Next, another embodiment of this invention will be described. 6 is a vertical cross-sectional view of the fluid container to which the fluid discharge pump 1 according to the second embodiment of the present invention is applied.

This fluid container is composed of a fluid discharge pump 1 according to the present invention, a nozzle head 2, a lid 3, and a fluid reservoir 4 for storing a fluid therein. Here, the nozzle head 2 is connected to the discharge part 41 for discharging a fluid, the press part 42 pressed at the time of discharge of a fluid, and the press part 42, and the press part 41 receives a pressure. When the pressure is transmitted to the piston 12 to be described later has a hollow connecting cylinder 43 for lowering the piston 12. In addition, the fluid reservoir 4 has a cylindrical cylinder member 5 and a piston member 6 which moves inside the cylinder member 5 in the vertical direction.

The fluid discharge pump 1 and the fluid reservoir 4 are connected in a liquid tight state through the packing 44.

In this fluid container, the pressurizing portion 42 in the nozzle head 2 is pressed to reciprocate in the vertical direction, and the fluid reservoir 4 is operated by the action of the fluid discharge pump 1 to be described in detail later. The fluid stored therein is discharged from the discharge portion 41 in the nozzle head 2.

As the fluid in the fluid reservoir 4 decreases, the piston member 6 moves in the cylinder member 5 in the direction of the nozzle head 2, as shown in FIG.

Next, the structure of the fluid discharge pump 1 which concerns on 2nd Embodiment of this invention is demonstrated. The same code | symbol is attached | subjected about the same member as 1st Embodiment mentioned above.

8 and 9 are longitudinal cross-sectional views of the fluid discharge pump 1 according to the second embodiment of the present invention. In the meantime, FIG. 8 shows that the connecting cylinder 43 is lowered due to the pressing portion 42 in the nozzle head 2 being pressed, and FIG. 9 shows that the nozzle head 2 is opened. Therefore, the connecting cylinder 43 is showing the state which is raising.

The fluid discharge pump 1 is a cylinder (11), a piston (12) capable of reciprocating within the cylinder (11), and a cylinder (12) in synchronism with the piston (12) attached to a part of the piston (12). 11) A cylindrical shape 13 for reciprocating the inside is provided.

A spring 15 is disposed between the support member 14 disposed below the cylinder 11 and the lower surface of the piston 12. For this reason, when the pressing part 42 of the nozzle head 2 shown in FIG. 6 is pressed, this pressure is transmitted to the piston 12 via the connecting cylinder 43 and the cylinder 13, and the piston ( 12 is lowered in the cylinder 11 in response to the spring force due to the spring (15). On the other hand, when the pressure to the nozzle head 2 shown in FIG. 6 is released, the piston 12 raises the inside of the cylinder 11 by the action of the spring 15.

Below the cylinder 11, the resin-shaped valve 21 is arrange | positioned. A spring 22 is disposed between the valve 21 and the support member 14. The valve 21 is urged toward the toilet seat comprised of the opening part 16 formed in the lower end of the cylinder 11 by the action of this spring 22. As shown in FIG.

The toilet seat comprised from these valve 21, the spring 22, and the opening part 16 comprises an inflow valve mechanism.

The cylinder 13 is composed of a flange portion 23, a cylinder 24, a depa portion 25, and a cylinder portion 26. Inside the barrel 13, a set of resin valves 31 and 32 and springs 33 which bias these valves 31 and 32 in a direction away from each other are disposed. It is.

The valve 31 abuts above the toilet seat composed of the depressed portion 25 of the tubular shape 13 by the action of the spring 33. Moreover, the valve 32 abuts below the toilet seat which consists of an opening formed in the center of the flange part 23 of the cylindrical shape 13 by the action of the spring 33. As shown in FIG.

The toilet seat comprised by the valve | bulb 31, 32, the spring 33, the toilet seat which consists of a cylindrical depa part 25, and the opening formed in the center of the flange part 23 of the cylindrical shape 13 flows out. Construct a toilet. In addition, in particular, the toilet seat composed of the valve 31 and the tubular depa part 25 constitutes an inflow valve, and is composed of an opening formed in the center of the flange part 23 of the valve 32 and the tub 13. The toilet seat constitutes an inverse rise.

The lower end of the connecting cylinder 43 presses the valve 32 during the lowering operation of the piston 12, and the valve 32 is opened to the opening formed in the center of the flange 23 of the tub 13. A plurality of protrusions 17 serving as pressure means for separating from the toilet seat constituted are formed.

Moreover, between the lower end part of the connection cylinder 43, and the upper end part of the cylinder shape 13 which comprises a part of piston 12, the space comprised between the inside of the connection cylinder 43 and the inside of the cylinder 11 The packing 51 is prevented from dropping the fluid in the cylinder 11 and prevents the fluid flowing into the cylinder 11 from flowing out of the area other than the discharge part 41 in the nozzle head 2.

This packing 51 is made of synthetic rubber having its outer diameter substantially conical in shape as shown in the perspective view of FIG.

Next, the discharge action of the fluid by the fluid discharge container which adjusted the fluid discharge pump 1 mentioned above is demonstrated.

In the initial state, as shown in Fig. 6, the valve 21 is positioned on the toilet seat formed by the opening 16 formed at the lower end of the cylinder 11, and the valve 31 is positioned on the toilet seat formed of the cylindrical depa part 25. Moreover, the valve 32 is abutted by the toilet seat which consists of the opening formed in the center of the flange part 23 of the cylindrical shape 13, respectively. In addition, the cylinder 11 is filled with a fluid.

When the press part 42 in the nozzle head 2 in this state is pressurized, as shown in FIG. 8, the connecting cylinder 43 descends and the several protrusion part 17 formed in the lower end part is a valve | bulb Press (32). As a result, the valve 32 is spaced apart from the toilet seat composed of an opening formed in the center of the flange portion 23 of the tub 13 against the spring force caused by the spring 33.

Moreover, the pressure applied to the nozzle head 2 is transmitted to the piston 12 via the connecting cylinder 43 and the cylinder shape 13. Due to this, the piston 12 descends the inside of the cylinder 11 together with the cylinder 13. As the piston 12 descends, the valve 31 is pressed by the pressure of the fluid filled in the cylinder 11. For this reason, as shown in FIG. 8, the valve 31 is spaced apart from the toilet seat which consists of the deformation part 25 of the cylindrical shape 13 against the elasticity force by the spring 33, and the cylindrical shape 13 Fluid flows into

Moreover, by the action of the spring 15, the piston 12 raises the inside of the cylinder 11 with a cylindrical shape. By the pressure-reducing action in the cylinder 11 with the rise of this piston 12, the valve 21 is pressurized by the fluid stored in the fluid reservoir 4 shown in FIG. For this reason, as shown in FIG. 9, the valve 21 is spaced apart from the toilet seat which consists of the opening part 16 formed in the lower end of the cylinder 11, against the repulsion force by the spring 22, The cylinder 11 The fluid flows in the fluid reservoir 4 in the container.

On the other hand, the valve 31 abuts against the toilet seat composed of the deformed portion 25 of the tubular shape 13 as shown in Fig. 9 by the spring force of the spring 33. For this reason, the fluid in the cylinder 13 and the connection cylinder 43 is not attracted to the cylinder 11 side.

Here, the valve 31 is forcibly brought into contact with the toilet seat composed of the depressed part 25 of the tubular shape 13 by the action of the spring 33. For this reason, even when using a liquid with high clay, a gel, etc. as a fluid, it becomes possible to reliably contact the toilet seat which consists of the valve part 31 and the deform part 25 of the tubular shape 13. , It is possible to effectively prevent the fluid in the cylinder 13 and the connecting cylinder 43 from being attracted to the cylinder 11 side.
