Description

  The present invention relates to a discharge device and a discharge product for discharging contents.

Conventionally, there is an aerosol product using a compressed gas such as nitrogen gas as a pressurizing agent. The compressed gas is filled in the gas phase portion in the container body to pressurize the contents, and the contents are discharged (injected) by opening an aerosol valve fixed to the container body.
The aerosol product can discharge the contents while changing the direction (angle) in which it is used. However, depending on the angle, there is a problem that the pressure agent is removed without being discharged and the pressure agent cannot be used. Therefore, as in Patent Documents 1 and 2, there is an aerosol valve in which the pressurizing agent is difficult to escape even if the orientation of the aerosol product is changed.
In the aerosol valves of Patent Documents 1 and 2, a flexible tube is connected to the housing, and a weight is provided near the tip opening of the tube. Since the weight moves according to the inclination of the aerosol product, the pressurizing agent is difficult to come off.
Moreover, there exists a double aerosol product which equips the inside of a container main body with the flexible inner bag like patent document 3. FIG. Double aerosol products are used in any orientation because the inner bag is filled with the contents, the space between the inner bag and the container body is filled with a pressure agent, and both are sealed in a sealed state. However, the contents can be discharged without the pressurizing agent coming out.
On the other hand, there is a conventional pump-type discharge device that discharges contents with pressure from a piston (Patent Document 4).

Japanese Patent No. 3557529 56-39578 JP-A-9-118380 WO2003 / 103849

The aerosol valves of Patent Documents 1 and 2 have a limit in the direction in which they can follow, and if the aerosol product is tilted too much, there is a problem that the pressurizing agent falls out and cannot be used.
The double aerosol product of Patent Document 3 has a problem that the pressurizing agent cannot be discharged even when the entire content is discharged, and cannot be safely discarded.

  Therefore, the present invention can discharge the contents even when the pressure agent is released and the pressure in the container is lowered, or even when the pressure agent is completely removed and the pressure is equal to the atmospheric pressure, and the contents can be discharged safely. It is an object of the present invention to provide a discharge device and a discharge product that can be discarded.

In the discharge device of the present invention (Claim 1), a valve body having a stem, a piston, and a housing for housing them is attached to a container body filled with a content and a pressurizing agent that pressurizes the content. The contents are discharged by the pressure of the pressurizing agent by the first operation for operating the stem, and the contents are discharged by the pressurizing force of the piston by the second operation for operating the piston.

  It is preferable that the stem also serves as a piston rod (claim 2).

  In such a discharge device, it is preferable that the valve mechanism includes a switching mechanism for switching between restriction and release of the second operation.

  Furthermore, it is preferable that the first operation is a pushing operation by a first operation amount downward of the stem, and the second operation is a pushing operation exceeding the first operation amount (Claim 4).

  Further, it is preferable that the first operation is tilting of the stem and the second operation is pushing of the stem (claim 5).

  The discharge product of the present invention (Claim 6) is characterized in that the above-mentioned discharge device is filled with contents and a pressure agent.

The discharge device and the discharge product of the present invention (claims 1 and 6) are easy to use because the contents can be discharged with the pressure of the pressurizing agent by the first operation of operating the stem.
Even if the pressurizing agent is discharged due to an incorrect usage method and the pressure becomes equal to the atmospheric pressure and cannot be discharged, the contents can be discharged to the end by the pressurizing force of the piston by the second operation of operating the piston. Therefore, it is economical.
Moreover, since the pressurizing agent does not remain after the content is used up like a double aerosol product, it can be safely disposed of.

When the stem also serves as a piston rod (Claim 2), it is attached to the container body via a common housing, so that the space is saved and the container body can be made compact.
Moreover, since the discharge by a pressurizing agent and the discharge by a pump mechanism can be performed by the operation of the same stem, it is easy to use.

  In such a discharge device, when the valve mechanism includes a switching mechanism that switches between restriction and release of the second operation (Claim 3), the pressure agent is sufficiently filled by setting the restriction state. An erroneous operation for performing the second operation in the state can be prevented.

  Furthermore, when the first operation is a push-down by a first operation amount downward of the stem and the second operation is a push-up exceeding the first operation amount (Claim 4), the first operation and the second operation are performed. The operation is easy to use because the operation direction is the same. Furthermore, since the operation amount of the second operation is large, it is easy for the consumer to recognize and an erroneous operation can be prevented.

  Further, when the first operation is a tilt of the stem and the second operation is a push of the stem (Claim 5), since the operation directions of the first operation and the second operation are different, it is easy for consumers to recognize. Incorrect operation can be prevented.

An embodiment of the discharge apparatus and discharge product of the present invention will be described with reference to FIG. A discharge product 20 shown in FIG. 1 includes a discharge device 1 and an aerosol composition A filled therein. The discharge device 1 includes a container main body 21 and a valve (valve mechanism) 22 attached to the mouth of the container main body 21. A push button 8 is attached to the stem 3 of the valve. The aerosol composition includes a content 24 and a pressurizing agent 25.
1 shows a state where the stem 3 is not pushed (hereinafter referred to as an initial state).

  The discharge device 1 is a so-called aerosol discharge that discharges the content 24 filled in the container body 21 by the pressure of the pressurizing agent 25 and a so-called pump that operates the piston to pressurize and discharge the content. The discharge can be switched and used.

The container body 21 has a bottom portion, a cylindrical body portion 21c, and a mouth portion 21a, and is formed into a bottomed cylindrical shape using a metal such as aluminum or tinplate, or a synthetic resin such as polyethylene terephthalate or polypropylene. It is a conventionally well-known thing. The trunk portion 21c may be partially inflated or constricted, and the entire trunk portion may be spherical or rugby ball-shaped.
A screw portion 21b is formed on the outer periphery of the mouth portion 21a, and a cap 23 can be detachably screwed to the screw portion 21b. The cap 23 is attached in an airtight manner by sandwiching the flange (the flange 2 e) of the housing of the valve 22 between the tip of the mouth 21 a of the container body 21 and the inner surface of the cap 23 via the packing 13.

The valve (valve mechanism) 22 has a function as an aerosol valve that discharges the content 24 by the pressure of the pressurizing agent and a function as a pump that discharges the content 24 by the pressurizing force by the vertical movement of the piston. It is.
From here, FIG. 2 will be described together. The valve 22 includes a housing 2 sandwiched between a mouth portion 21a of the container body and a cap 23, a stem 3 accommodated in the housing 2 so as to be movable up and down, and a stem 3 inserted therein to slide the inner periphery of the housing. A piston 4 that moves, a valve 5 that closes the introduction hole 2a at the bottom of the housing, and a spring 3b that biases the stem 3 upward are provided.

The housing 2 is provided with functions of aerosol discharge and pump discharge in a common housing. The housing 2 includes a cylindrical portion 2d, a flange portion 2e extending outward from the vicinity of the upper end of the cylindrical portion 2d, and a cylindrical protruding portion 2g provided on the bottom portion 2c of the cylindrical portion 2d to which the tube 2h is attached. An introduction hole 2a for introducing the contents 24 from the tube 2h into the housing is formed between the cylindrical portion 2d and the protruding portion 2g.
The tube 2h has an upper portion that fits into the protruding portion 2g and a lower end that extends to the vicinity of the bottom of the container body, and sucks up the contents in the container body and introduces them into the housing.

A communication hole 2b for communicating the container main body 21 and the housing 2 is formed in the peripheral wall of the cylindrical portion 2d. The communication hole 2b is located above the cylindrical portion 2d of the housing 2 and is closed by the piston 4 at the rising end. That is, when the piston 4 is lowered, the space above the piston 4 in the housing 2 is negative compared to the storage chamber B, and prevents the piston 4 from being hindered from descending.
A cylindrical annular piece 2f projects upward from the upper surface of the flange 2e. Further, the packing 13 is held on the lower surface of the flange portion 2e, the packing 13 is placed on the upper surface of the mouth portion 21a of the container body 21, and the cap is screwed onto the screw portion 21b of the mouth portion. The packing 13 is compressed and sealed between the flange portion 2e and the upper surface of the mouth portion 21a, and the housing 2 is fixed to the container body 21.

From here, it demonstrates using FIG. 2a. The stem 3 not only discharges the contents by opening the stem hole 3a, but also serves as a piston rod for operating the piston 4 having a pump function.
The stem 3 is formed with a stem hole 3a that communicates the inside and outside of the housing. The stem 3 is urged upward with respect to the housing 2 by a conventionally known urging member such as a spring 3b. The spring 3b uses the bottom 2c of the housing 2 as a scaffold, and biases the lower end of the stem 3 upward.

  The stem 3 is mounted on the inner stem 6 provided with the stem hole 3a and the upper portion of the inner stem 6, protrudes upward from the mouth portion 21a of the container body 21, and the push button 8 is provided near the upper end thereof. It consists of an external stem 7. Further, the outer stem 7 may be rotatably provided on the inner stem 6.

The inner stem 6 has a downward hook-like shape, and has a large-diameter hook-like portion 6a to which one end of the spring 3b is locked on the lower surface thereof, and a small-diameter protruding upward from the vicinity of the center of the upper surface of the hook-like portion 6a. And a rod-shaped portion 6b.
An annular groove 6c that engages with the lower portion of the piston 4 is formed around the base of the rod-like portion 6b on the upper surface of the flange-like portion 6a.
A cylindrical portion 6d is provided in the vicinity of the base of the rod-like portion 6b, and the stem hole 3a is formed on the peripheral surface thereof. Further, the rod-like portion 6b has an inclined portion 6e whose diameter is reduced upward from the upper end of the cylindrical portion 6d, and a small cylindrical portion 6f having the same diameter is formed upward from the upper end of the inclined portion 6e. A communicating passage 6g is formed in the rod-like portion 6b in the axial direction, and communicates with the stem hole 3a at the lower end thereof.

The outer stem 7 has a cylindrical skirt portion 7a that is substantially the same diameter as the flange-like portion 6a and is disposed with a gap between the outer periphery of the rod-like portion 6b, and extends upward from the skirt portion 7a. And a cylindrical portion 7b into which the upper half of the small cylindrical portion of the rod-shaped portion 6b is inserted. In the initial state, the entire cylindrical portion 7b protrudes from the mouth portion 21a (see FIG. 1) of the container body 21, and the push button 8 is attached above the protruding portion.
The inner stem 6 and the outer stem 7 operate integrally when the push button 8 (see FIG. 1) is depressed, and the lower end (pushing portion 7c) of the skirt portion 7a of the outer stem is a contact portion of the piston 4 described later. The piston is moved downward in contact with 4c.

Returning to FIG. 1, a pressing member 9 is provided at the tip of the annular piece 2 f of the housing 2. The pressing member 9 includes a cylindrical spacer portion 9a inserted so as to be in close contact with the inner peripheral wall of the cylindrical portion 2d of the housing 2, and an annular seal piece 9b extending outward in the radial direction from the upper edge of the spacer portion 9a. And have. The spacer portion 9a has its lower end in contact with the upper end of the piston, and positions the piston in the initial state. In the annular seal piece 9 b, the lower surface of the outward flange is in contact with the upper surface of the annular piece 2 f of the housing 2. On the other hand, the lower surface of the inward flange of the annular seal piece 9b presses the upper surface of the skirt portion 7a of the outer stem 7 when the stem is at the rising end, and restricts the stem 3 from protruding upward.
Further, a sealing material 10 having a substantially L-shaped cross section is provided between the upper surface of the annular seal piece 9b and the inner end of the inward flange. The sealing material 10 is pressed on the lower surface of the cap 23 by screwing to seal between the pressing member 9 and the cap 23 and between the pressing member 9 and the external stem 7. For this reason, even if the stem 3 moves up and down, the airtightness between the container main body 21 and the stem 3 is maintained.

The piston 4 has a double cylindrical shape, and includes an inner stem hole closing portion 4a, an outer communication hole closing portion 4b, and an abutting portion 4c connecting them. Piston 4 has internal stem 6
And an external stem 7 are provided so as to be movable up and down. The material of the piston 4 is formed of a synthetic resin such as polypropylene or polyacetal.

  From here, it demonstrates using FIG. 2b. The stem hole closing portion 4a is formed in such a shape as to contact the peripheral surface of the cylindrical portion 6d, the inclined portion 6e, and the small tube portion 6f of the inner stem 6, and the diameter is reduced upward from the contact portion 4c. A taper seal portion 4e and a cylindrical tail portion 4d extending upward are provided at the upper portion thereof, and a cylindrical seal portion 4f is provided downward from the contact portion 4c. In an initial state, the inner surface of the taper seal portion 4e is in contact with the outer surface of the inclined portion 6e of the inner stem 6, and the lower end of the cylindrical seal portion 4f is engaged with the annular groove 6c of the inner stem 6, 3a is sealed. The tail portion 4d is inserted in the gap between the rod-like portion 6b of the inner stem 6 and the skirt portion 7a of the outer stem 7 near the tip, and is deeply inserted into the gap when the stem 3 is pushed.

  The communication hole closing portion 4b is connected to the abutting portion 4c in the vicinity of the center in the vertical direction, and extends so that the upper and lower ends are inclined outward in the radial direction with the central portion as a base end. The communication hole closing portion 4b is elastically in contact with the inner surface of the cylindrical portion 2d of the cylinder 2 by bending the vicinity of the upper and lower ends inward in the radial direction. And it is provided so that the inside of the cylinder part 2d may be moved up and down, maintaining the elastic contact state. In FIG. 1, the communication hole 2b is closed at a position above the communication hole closing portion 4b.

  As shown in FIG. 2a, when the piston 4 and the stem are in the initial state, the pushing portion 7c of the external stem 7 and the abutting portion 4c of the piston 4 are disposed with a first operating amount H1 therebetween. Yes.

  Returning to FIG. 1, when the pressure in the container body is usually high, the valve 5 moves upward by the pressure to open the introduction hole 2a. On the other hand, when the pressure in the container body is lowered and pump discharge is performed, the inside of the storage chamber B is pressurized by the downward movement of the piston 4, the ball moves downward, and the introduction hole 2a is closed. When the contents are discharged by pump discharge and the piston moves upward, the ball moves upward to release the introduction hole 2a and introduce the contents into the storage chamber B. The reservoir B is a space surrounded by the piston 4, the bottom 2b of the housing 2, and the cylinder 2c.

The cap 23 is formed with a female screw portion 23 a on the inner peripheral surface thereof to be screwed into the screw portion 21 b of the container main body 21. A step portion 23b (see FIG. 3a) is formed on the inner surface of the ceiling portion, and the sealing material 10 is pressed by the step portion 23b. The center of the ceiling is open, and the external stem 7 protrudes. A cylindrical regulation cylinder portion 11 extends upward from the periphery of the opening.
The cap 23 is screwed into the container body 21 by a screw mechanism, but the cap 23 may be fixed by caulking near the upper end of the mouth portion 21a of the container body 21.

As shown in FIGS. 3a and 3b, the restriction cylinder portion 11 has a cylindrical shape as a whole, and a notch portion whose height changes stepwise is formed inside thereof. The upper surface of each staircase that forms the notch is an upper first operation restricting portion 11a and a second operation restricting portion 11b that is lower than the first operation restricting portion 11a. Further, a side surface portion of the wall that continues to the first operation restricting portion 11a and protrudes further upward is a stopper 11c, and is a portion that restricts the rotation of the push button 8 in the L direction (see FIG. 3b).
The heights of the first operation restricting portion 11a and the second operation restricting portion 11b are the first operation amount H1. Further, the height of the second operation restricting portion 11b is set to be equal to or greater than the maximum stroke of the stem 3 (second operation amount H2).

Returning to FIG. 1, the push button 8 is formed with a cylindrical groove 8a extending upward from the lower surface thereof. Further, a projection 8b (see FIG. 3b) protruding outward in the radial direction is provided on the inner wall surface in the groove 8a.
And the regulation cylinder part 11 of the cap 23 is inserted in the said groove | channel 8a. A switching mechanism 12 is constituted by the restriction cylinder portion 11 and the protrusion 8b.
Further, the outer surface of the inner surface of the groove 8 a of the push button 8 is in sliding contact with the outer peripheral surface of the regulating cylinder portion 11. That is, the rotation and the downward movement of the push button 8 are guided by the regulation cylinder portion 11. Therefore, the second operation for moving the push button 8 greatly downward and operating the pump mechanism is smooth and stable.

In addition, you may provide the said control cylinder part 11 in the empty space above the container main body 21. FIG. For example, you may make it protrude upwards from a shoulder part. Further, a protrusion 8b that comes into contact with the regulating cylinder portion 11 may be provided at a portion of the outer stem 7 that protrudes from the container body 21 to the outside.
Further, in the above-described embodiment, the restriction cylinder portion 11 is provided in the cap 23. However, the restriction cylinder portion 11 may be provided in the push button 8, and the protrusion 8b may be provided in the cap 23.

Next, how the switching mechanism 12 operates will be described with reference to FIG. The state where the lower surface of the protrusion 8b of the push button 8 is placed on the first operation restricting portion 11a is the lock state T1 of the switching mechanism 12. In the locked state T1, the lower surface of the protrusion 8b is in contact with the first operation restricting portion 11a, and the push button 8 cannot be pushed downward.
When the push button 8 in the locked state T1 is rotated in the R direction (see FIG. 3b), the protrusion 8b is disposed above the second operation restricting portion 11b. Therefore, until the push button 8 comes into contact with the second operation restricting portion 11b, that is, the stem 3 (see FIG. 2a) can be moved downward by the first operation amount H1, thereby opening the stem hole 3a (the piston is (Does not work) aerosol discharge is possible. This state is an aerosol discharge state T2. Further, the push button 8 in the locked state T1 cannot hit the stopper 11c and rotate in the L direction. For this reason, the rotation from the lock state T1 to the aerosol discharge state T2 is ensured. That is, when the push button 8 is rotated in the opposite direction or rotated more than once, it is difficult to grasp which state is present.
Further, the push button 8 at the position of the aerosol discharge state T2 is rotated in the R direction and disposed beyond the second operation restricting portion 11b. This state is a free state T3. At this time, the push button 8 can be pushed to the lower end with the maximum stroke (the sum of the first operation amount H1 and the second operation amount H2), and the piston 4 can be operated to discharge the pump.

The content 24 (see FIG. 1) is a liquid in the container, and is discharged into a mist (mist), gel, cream, foam, or the like state by a pressurizing agent to be described later. The use is not particularly limited. For example, cosmetics such as lotion, cleansing, cooling agent, colon, quasi-drugs such as antiperspirants, insect repellents, insecticides, anti-inflammatory analgesics, anti-itch agents, disinfectants, etc. Examples include household items such as pharmaceuticals and cleaning agents, and industrial items such as lubricants and rust inhibitors.
The pressurizing agent 25 (see FIG. 1) preferably uses a compressed gas, and examples thereof include nitrogen, carbon dioxide, nitrous oxide, compressed air, argon, and mixtures thereof.

Next, the manner in which the valve 22 of the discharge device 1 discharges aerosol and pump will be described with reference to FIG.
In the initial state (S1) where the push button 8 is not pushed down, the stem 3 and the piston 4 are both at the rising end by the biasing force of the spring 3b, and the stem hole 3a is closed by the stem hole closing portion 4a of the piston. When the contents are pressurized by the pressure of the pressurizing agent in the container body, the introduction hole 2a is released and the contents are introduced into the storage chamber B.

  Next, the push button 8 is rotated in the R direction from the locked state T1 to the aerosol discharge state T2 (see FIGS. 4 and 3b). When the push button 8 is depressed, the stem 3 moves downward by the first operating amount H1. However, the piston does not move downward and is at the rising end. At this time, the stem hole 3a moves below the stem hole closing portion 4a and is released. As a result, the content of the storage chamber B is continuously discharged from the push button 8 through the stem hole 3a to the outside by the pressure of the pressurizing agent 25 in the container body 21 (see FIG. 1), and the lower introduction hole New contents are introduced into the storage chamber B from 2a. (State S2). At this time, the pushing portion 7 c of the external stem 7 is in contact with or close to the contact portion 4 c of the piston 4.

  After that, when the pressure of the pressurizing agent becomes small and it becomes difficult to discharge, or when the pressurizing agent 25 runs out due to misuse, the push button 8 is further rotated in the R direction to be in the free state T3. (Refer to FIG. 4 and FIG. 3B), and the first operating amount H1 is pushed by the operating amount obtained by adding the second operating amount H2. Then, the pushing portion 7c of the external stem 7 abuts on the abutting portion 4c of the piston 4 and pushes the piston 4 downward. As a result, the piston 4 moves downward, the communication hole closing portion 4b is separated from the communication hole 2b, and the communication hole 2b is opened. For this reason, the pressure in the container main body 21 and the pressure on the upper surface side of the piston 4 become equal, and the volume of the storage chamber B decreases due to the lowering of the piston 4 and the internal pressure of the storage chamber B increases. Therefore, the valve 5 closes the introduction hole 2a, and the content 24 in the storage chamber B is discharged from the push button 8 to the outside through the stem hole 3a (state S3).

  After the contents 24 (see FIG. 1) are discharged, the stem 3 is biased upward by the spring 3b, and the stem 3 and the piston 4 are returned to their original positions (state S1). At this time, since the storage chamber B has a negative pressure, the contents 24 are sucked up from the introduction hole 2a. Then, the communication hole 2b and the stem hole 3a are closed.

FIG. 6 shows another embodiment of the discharge product. The same parts as those of the discharge product 20 described with reference to FIG. 1 are denoted by the same reference numerals and description thereof is omitted.
The discharge device 31 used for the discharge product 30 has the first operation to tilt the stem 3. The piston 4 does not include the stem hole closing portion 4a, and the upper surface of the flange-shaped portion 6a of the internal stem 6 does not include the annular groove 6c that locks the lower end of the cylindrical seal portion of the stem hole closing portion 4a. . On the other hand, an annular protrusion 6h is formed on the periphery of the upper surface of the bowl-shaped portion 6a. The annular protrusion 6h contacts the lower surface of the contact portion 4c and seals between the stem hole 3a and the storage chamber B. Further, in this discharge device 31, almost the same as the above-described discharge device 20, there is a space (first operation) between the pushing portion 7 c at the lower end of the skirt portion 7 a of the external stem 7 and the contact portion 4 c of the piston 4. A quantity H1) is provided. This space is used for tilting the stem 3 in the first operation. When the stem 3 is tilted using this space, a gap is formed between the annular protrusion 6h and the lower surface of the contact portion 4c, and the stem hole 3a is opened.

  The second operation of the discharge device 31 is performed by the downward movement of the stem 3 in substantially the same manner as the discharge device 1. That is, when the push button 32 is pushed down, the annular projection 6h of the inner stem is separated from the lower surface of the abutting portion 4c of the piston, and the stem hole 3a is released. When the operation amount of the push button exceeds the first operating amount H1, the pushing portion 7c of the external stem pushes down the abutting portion of the piston 4, and the piston reduces the volume of the storage chamber B and the internal pressure of the storage chamber B is high. Become. Thereby, the contents 24 in the storage chamber B are discharged from the push button 32 to the outside through the stem hole 3a.

As shown in FIG. 7, a protrusion 32 a that protrudes outward is provided on the outer periphery of the push button 32 of the discharge device 31. Further, the restriction cylinder portion 33 of the cap has a cylindrical shape, and the push button 32 can be tilted more than the first notch portion by removing the outer peripheral wall and the first cutout portion 33a cut out from the upper end while leaving the outer peripheral wall 34. A second cutout portion 33b cut out downward to the extent and a third cutout portion 33c cut out further downward than the second cutout portion are provided.

As shown in FIG. 8, in the locked state T4, the protrusion 32a of the push button is disposed in the first notch, and the inner surface of the outer peripheral wall 34 abuts the outer periphery of the protrusion 32a to restrict the tilt of the push button. At the same time, the upper surface of the first notch 33a is in contact with the lower surface of the protrusion 32a to restrict the push button, so that the push button cannot be operated.
Next, when the push button 32 in the locked state T4 is rotated in the R direction (see FIG. 7), the protrusion 32a is disposed at the position of the second notch 33b, and the outer peripheral wall 34 is not provided outside. Therefore, the push button 32 can be tilted. However, since the lower surface of the protrusion 32a is in contact with the upper surface of the second notch, aerosol discharge can be performed, but pump discharge cannot be performed. This state is an aerosol discharge state T5.
Further, when the push button 32 in the aerosol discharge state T5 is rotated in the R direction and the protrusion 32a is disposed at the position of the third notch 33c, the protrusion 32a is not restricted, so that the push button can be pushed. The pump can be discharged. This state is a free state T6.

The first operation and the second operation by the push buttons of the valve and the pump may be operated in parallel. The switching mechanism 12 in this case is realized by hiding the upper part with a cover so that the push button of the pump cannot be operated during the first operation. Further, the push button of the pump may be rotated, and a baffle member may be disposed on the lower surface of the push button so as not to be able to be pushed downward in the same manner as the restriction cylinder portion 11.
Further, the first operation and the second operation by the push buttons of the valve and the pump may be interlocked.
