[0003]
In a conventional discharge device, the contents in a container are discharged by pressing a push button of an aerosol device with a finger to open a valve or operating a pump of a pump device. The discharge mode is adjusted by a valve, a pump, and a mechanism of a discharge member. For example, a valve device that discharges a fixed amount by one discharge operation (Patent Document 1 and Patent Document 2 etc.), an intermittent injection device that repeats injection and stop (Patent Document 3 etc.), a discharge amount and a discharge pattern according to a valve operation amount (Patent Documents 4 and 5, etc.), a valve device that suppresses the flow rate to reduce the discharge amount (Patent Documents 6, 7 and the like), from the operation of a push button to the discharge There is a timer-type discharge device that takes a long time (Patent Documents 8 and 9), and the device is fixed or attached to a container, and the device is directly operated by hand or finger.
[0004]
As an improvement of such a conventional aerosol device, the present applicant has proposed an ejection reservation type discharge device (aerosol container) (aerosol container described in Japanese Patent Application No. 2002-116879 which is not disclosed at the present time). This is a means for controlling spraying, such as mechanical signals such as clocks and alarms, audible signals such as telephone ringtones, visual signals of indoor and outdoor lights, and tactile stimuli (tactile signals) such as electric fans. (Transmission signal) is received by a receiver provided in the aerosol container, and the injection and stop are controlled by transmitting the signal to an electromagnetic valve or the like for controlling injection.
[0005]
The basic concept of the aerosol device is to remotely control the start and end of spraying, the operation pattern, and the like, and does not specify the position where an electromagnetic valve is provided. However, a specific embodiment shows that an electromagnetic valve is provided between the stem and the injection port outside the aerosol container. Although this one tends to be cumbersome and large in appearance, there is an advantage in that it is always installed in that the manufacturing cost is reduced. However, since such an installation type discharge device basically does not need to be considered in terms of lightness and appearance, it is difficult to always install it in a narrow place or to operate it by hand. Not suitable.
[0006]
[Problems to be solved by the invention]
It is a technical object of the present invention to provide a discharge device which is easy to use even in a narrow place and even when operated by hand, and to provide a discharge device which can easily change and select a discharge method of contents. .
[0007]
[Means for Solving the Problems]
A discharge device with a built-in drive device according to the present invention (Claim 1) includes a container body, a valve attached to an upper opening of the container body, and a valve for communicating and shutting off the inside and the outside of the container body, and the container body. And a drive device which is housed in the inside and is electrically operated, and control means for controlling the drive device from outside the container. The term "valve" as used herein means a conventionally known aerosol valve of a type for manually operating a stem.
[0008]
In such a discharge device with a built-in drive device, the control unit is provided outside the container body, and a transmitting unit that transmits a control signal that passes through the container body or the valve, and is provided inside the container body, and the transmitting unit And a receiving unit for receiving a signal from the communication device (claim 2). The transmission unit of the "control means" here is a signal such as infrared or radio waves that is transmitted by selecting and transmitting the start and end times of spraying, the amount of spraying, the method of spraying with a controller, etc. Signals that are transmitted using equipment, such as signals from lights such as fluorescent lights that illuminate, signals from telephone ringtones, and alarms such as timers and clocks, are also emitted regularly in the natural world. Signals by light or sound when using light or sound are also included.
[0009]
Further, it is preferable that at least a part of the container body or the valve transmits the magnetic field lines, and the transmitting unit and the receiving unit of the control unit transmit and receive the control signal of the magnetic field lines, respectively. . Further, at least a part of the container body or the valve transmits light, radio waves or sound waves, and the transmitting unit and the receiving unit of the control unit transmit and receive the control signals of light, radio waves or sound waves, respectively. It is preferable that there be (claim 4).
[0010]
Further, the control means includes an element housed in the container main body, which moves or deforms according to the posture of the container main body, and a sensor which detects the movement or deformation of the element and generates a control signal of a driving device. (Claim 5). Further, as the driving device, an electromagnetic valve which is provided in a passage from the inside of the container body to the stem of the valve and operates to communicate and shut off the passage can be adopted (claim 6).
[0011]
Further, the driving device may include a stirrer that stirs the contents in the container body, and a motor that drives the stirrer (claim 7). Further, the driving device may be a device that pulls or tilts the stem of the valve (claim 8).
[0012]
Further, the driving device may rotate the stem of the valve (claim 9). In this case, it is preferable that the lower part of the stem protrudes from the lower part of the housing of the valve and is connected to a driving device provided on the bottom surface of the container body (claim 10).
[0013]
[Action and effect of the invention]
A discharge device with a built-in drive device according to the present invention (claim 1) includes a drive device that is electrically operated in a container body, and control means for controlling the drive device from outside the container. Since the drive device is housed inside the container body in this way, the exterior of the container body is not different from the conventional one, so that it is easy to handle and easy to operate by hand. Further, since the container body of the discharge device acts as a case for protecting the driving device, the driving device is not damaged even if the container receives an external impact. In addition, since the drive unit is provided with control means that can be operated from outside the container, the effects obtained when the drive unit is operated (control of the discharge amount, adjustment of the discharge pattern, control of the discharge time, stirring of the contents to be discharged) , Selection of the valve to open, etc.).
[0014]
The control means is provided outside the container body, and includes a transmitting unit that transmits a control signal that passes through the container body or the valve, and a receiving unit that is provided inside the container body and receives a signal from the transmitting unit. In the discharge device (claim 2), a control signal transmitted from the outside of the discharge device passes through the container body or the valve and is received inside the container body. In other words, the signal for controlling the driving device housed in the container body passes through the container body or the valve, and this signal can be received by the receiving unit inside the container body. Electrical components including electric wires to be transmitted to the driving device and a control board of the driving device can be housed inside the container body. Therefore, the container may have a seal structure consisting only of a conventional stem gasket (stem rubber) and a mounting gasket, and is easy to manufacture and has little gas leakage. Further, the transmitter of the control signal may be arranged close to the outside of the container, or may be arranged at a position away from the container for remote operation. In this case, the method can be suitably adopted even when an undesired content such as an insecticide or a water repellent is discharged to the human body. Of course, even if the content is not harmful to the human body, it can be discharged by remote control.
[0015]
At least a part of the container body or the valve (hereinafter, the container body and the valve is simply referred to as a container) transmits magnetic field lines, and a transmitting unit and a receiving unit of the control unit transmit and receive a control signal of the magnetic field lines, respectively. In the case of the discharge device (claim 3), when a control signal based on the magnetic field lines is transmitted from the outside of the container, the signal of the magnetic field lines transmitted through the container can be received inside the container. Therefore, the container can be made of a synthetic resin or glass, or a metal such as aluminum having high strength that transmits magnetic lines of force.
[0016]
In addition, at least a part of the container transmits light, radio waves or sound waves, and the transmitting section and the receiving section of the control means transmit and receive control signals of light, radio waves or sound waves (claim 4). ), Different signals can be sent simply by changing the wavelength. Therefore, in addition to simple control of only turning on / off the driving device, complicated control such as changing the discharge amount stepwise becomes easy. In addition, the part which transmits light or a radio wave can be made of transparent glass or synthetic resin.
[0017]
A discharge device comprising: an element that moves or deforms in accordance with the posture of the container body; and a sensor that detects the movement or deformation of the element and generates a control signal for a driving device. In the case of, when the container is tilted or turned upside down, a predetermined element moves or deforms according to their movement, a sensor detects the movement or deformation, and a control signal is sent to the driving device. Can be sent. In this case as well, the electric device need only be provided inside the container body, and there is no need to provide an external transmitting device. Therefore, the appearance of the container is very simple. Further, since the driving device can be controlled by holding and tilting the container, the spraying operation and the like can be easily performed.
[0018]
In the case where the driving device is a solenoid valve provided in a passage from the inside of the container body to the stem of the valve and operates to communicate / block the passage (claim 6), that is, the valve and the solenoid valve are connected in series. If so, the solenoid valve can be controlled by a signal from the control means. Therefore, if the valve is set in advance so that the inside and outside of the container can be communicated, the contents will be discharged when the solenoid valve receives a signal from the control means, for example, an ON signal. On the other hand, if the valve is set to the shut-off state as opposed to the above, the contents will not be discharged even if the solenoid valve receives the ON signal. If the valve is set in advance so that the inside and the outside of the container are shut off, the solenoid valve does not discharge the contents even if it receives the ON signal, so that erroneous operation can be prevented beforehand.
[0019]
In the case where the driving device is a discharge device including a stirrer that stirs the contents in the container body and a motor that drives the stirrer, when the driving device is operated, the stirrer is driven by the container main body. The contents can be agitated and the concentration of the contents can be made uniform.Therefore, the contents consist of powders such as antiperspirants and scratches, and water and oil components. Alternatively, even when the content forming an emulsion, that is, the content that is easily separated in a short time is discharged for a long time, the content having a stable concentration or the like can be discharged.
[0020]
When the driving device pulls or tilts the stem of the valve (claim 8), the valve for manual operation can also be used as the valve for automatic operation. Therefore, there is no need to provide an extra solenoid valve.
[0021]
In the case where the driving device is a discharge device for rotating the stem of the valve (claim 9), since the ejection member such as the ejection button attached to the stem also rotates, the contents can be ejected over a wide range of 360 degrees. Can be. In addition, since the rotation speed can be easily adjusted, the diffusion state of the ejected particles can be adjusted. Further, in the case of a discharge device in which the lower portion of the stem projects from the lower portion of the housing of the valve and is connected to a driving device provided on the bottom surface of the container body, a heavy driving device is disposed at the bottom of the container. Therefore, the stability is improved.
[0022]

FIG. 13 is a cross-sectional view showing another embodiment of a button according to the present invention.
[0023]
The aerosol device A with a driving device shown in FIG. 1 is attached to a container 3 composed of a container body 1 and an aerosol valve 2 attached to an upper end opening of the container body 1 and a stem 4 housed in a housing of the aerosol valve 2. Injection button 5, an electromagnetic valve 6 fixed to the lower part of the housing, a transmitting unit 7 transmitted from outside the container 3, and a receiving unit 8 receiving a signal from the transmitting unit 7 inside the container 3. Control means 9 and a cord 10 for connecting the receiving section 8 to the solenoid valve 6.
[0024]
The container body 1 is not particularly limited, and a container conventionally used as an aerosol container, such as a metal container such as aluminum or tinplate, a resin container such as polyethylene terephthalate, or a glass container such as pressure-resistant glass is used. be able to. As described later, in this embodiment, light such as infrared light is used as a signal medium. Therefore, when the above-mentioned metal body is used as the container body 1, at least a portion of the wall of the body of the container body where the receiving portion 8 is attached is made of a transparent glass or a synthetic resin such as an infrared ray. A transmission section 11 made of an optical material is provided. Even if the entire container body 1 is made of transparent glass or transparent synthetic resin, there is no problem in operation and effect.
[0025]
The type of the aerosol valve 2 is not particularly limited, and a conventionally known push-down type or tilt type can be used. The aerosol valve is pushed up by a spring accommodated in the housing 12 and is kept airtight by being pressed against a stem gasket. When the stem 4 is pushed down into the housing 12 or tilts, the stem hole is opened. The valve is opened by moving below the stem gasket, and the contents are discharged by the pressure in the container. Also, when the stem is released from being pushed down or tilted, it returns to the original position by the spring and the pressure in the container, the valve is closed, and the contents are not discharged.
[0026]
The ejection button 5 is inserted into the stem 4, and the ejection button 5 is provided with a projection 5a around the ejection button and engages with the projection 5a on the container body 1 side so that the ejection button 5 can be kept pressed down. A flange 5b is provided. The projection 5a and the flange 5b can be engaged with each other when the ejection button is pressed downward and rotated. In this engaged state, the valve is opened, and the contents (aerosol composition) stored in the container can be discharged. However, in this embodiment, since the injection button 5 is connected in series with a solenoid valve 6 described later, the ejection can be performed only when both the aerosol valve 3 and the solenoid valve 6 are in the open state. Can be prevented. Therefore, by holding the ejection button 5 in the depressed state as described above, it is possible to set the state in which the contents are discharged immediately when the solenoid valve 6 is operated. In this case, the discharge operation can be performed from a place remote from the discharge device. When the injection button 5 is not operated, the contents cannot be injected even if the solenoid valve 6 is operated.
[0027]
The solenoid valve 6 is a driving device. The outlet of the solenoid valve is connected to a lower part of the housing 12 of the valve, and the dip tube 13 is connected to the inlet. The solenoid valve 6 is used to switch between communication and cutoff between the housing 12 and the dip tube 13, and a conventionally known solenoid valve can be used. A cord 10 for transmitting a signal received by the receiving unit 8 to the electromagnetic valve 6 is provided between the electromagnetic valve 6 and the receiving unit 8. That is, the ON signal transmitted from the transmitting unit 7 is received by the receiving unit 8 and transmitted to the electromagnetic valve 6 through the cord 10 to open the electromagnetic valve 6. At this time, since the injection button 5 is maintained in the operating state, the contents are discharged simultaneously with the opening of the solenoid valve 6. Conversely, when the OFF signal is transmitted via the receiving unit 8, the electromagnetic valve 6 is closed, but the discharge of the contents is stopped even when the valve remains open as described above.
[0028]
In this embodiment, a controller 14 that emits a signal using light such as infrared light as a medium is used as the transmission unit 7. The receiving section 8 has an element for converting light into an electric signal on the transmitting section 11 side, and a control board having an electric field and a circuit for amplifying the received signal on the opposite surface. Further, a cord 10 for transmitting an ON signal is provided between the solenoid valve 6 and the battery. Thus, when the controller 14 is operated toward the container from a distant position, a signal for operating the electromagnetic valve can be output by, for example, emitting infrared rays toward the receiving unit 8. In addition, since the signal passes through the wall that defines the inside and outside, when operating the drive device inside the container body from the outside of the container, a hole is provided in the container body to penetrate parts such as electric wires and shafts that are operated from the outside. A structure for sealing or sealing is not required.
[0029]
Next, the operation of this embodiment will be described.
In a state where the injection button 5 is not operated, the aerosol valve 2 is closed, so that even if the solenoid valve 6 is operated, no injection is performed. Therefore, injection due to malfunction is prevented. During transportation and storage, the valve 2 securely seals the valve. The ON signal 14 a emitted from the controller 14 is transmitted through the transmission unit 11 of the container 3 and received by the reception unit 8. The ON signal 14 a is received by the receiving unit 8 and transmitted to the solenoid valve 6 by the code 10. When the ON signal 14a is transmitted to the solenoid valve 6, the solenoid valve opens. At this time, if the push button is operated and the aerosol valve 2 is open, the contents are ejected through the dip tube 13, the solenoid valve 6 and the stem 4. When an OFF signal is issued by the operation of the controller 14, the operation of the solenoid valve is stopped and the spraying of the contents is stopped.
[0030]
The appearance of the discharge device A in this embodiment is basically the same as the conventional manual discharge device and has a simple form, and the transmission of the ON / OFF signal is performed by the controller 14 which is separated from the container 3. Because it is possible to do so, it does not come into contact with the container, and since it can be operated remotely, even if the contents may adversely affect the human body, it can be sprayed with confidence. The controller 14 may be configured to be detachably attached to the container body 1 in a state where the transmitting unit 7 and the receiving unit 8 face each other. In that case, the container 3 can be ejected by holding the container 3 in hand. Operation is also possible. Further, the controller 14 may be fixed to the container 3.
[0031]
As the receiving unit 8, a sensor that senses sunlight or fluorescent light can be employed. In the case of sunlight, for example, if the receiving unit 8 is set to face outside the window so that the morning sun is recognized as an ON signal, the light of the morning sun, which is the ON signal, passes through the transmission unit 11, so that the signal is received. It can be received at section 8. After the injection, an OFF signal is output by a timer or the like. The ON signal in this case is unstable because it is left to the weather, but the operation by the controller is unnecessary, which is further simplified. For example, when the morning sun comes into the room and the light is used to spray the cooling agent into the room, the sense of awakening becomes extremely refreshing.
[0032]
Also in the case of a fluorescent lamp, if the light of the fluorescent lamp is set in the receiving unit 8 so that the light of the fluorescent lamp is recognized as an ON signal, the light of the fluorescent lamp, which is the ON signal, passes through the transmitting unit 11 and is received by the receiving unit. 8 can be received. For example, when a fluorescent lamp is turned on when entering the toilet, a deodorant that deodorizes the odor remaining in the toilet and the odor of excrement can be automatically sprayed.
[0033]
Next, when the medium of the signal is a radio wave, the material of the transmitting portion 11 or the container may be a transparent material, or a radio wave transmitting material such as opaque glass or synthetic resin. In that case, the signal of the radio wave transmitted through the container can be received by the receiving unit. Further, in the case of sound waves, it is possible to transmit even metals other than the above-mentioned glass and synthetic resin, so that the entire container 3 may be made of metal such as aluminum or tin, synthetic resin or glass. In the case of a sound wave, an ultrasonic transmitter is used in addition to a sound transmitter such as a buzzer as a transmitter, and a microphone close to the inner wall of the container is used as a receiver.
[0034]
In the case where a transparent glass transparent portion 11 is provided in a part of the container body 1 as shown in FIG. 1 and the other part is made of metal such as aluminum, any signal of light, sound wave, radio wave, and magnetic force lines is not generated. The transmission part 11 can be transmitted. Note that the receiving section is preferably fixed to the inner surface of the container body 1. However, it can also be fixed to a solenoid valve. Further, an antenna is provided on the container 3, and a second transmitting unit is provided near the surface side of the transmitting unit 11 for amplifying the received radio wave and transmitting the amplified electric wave toward the receiving unit 8, and relays a signal from the controller to the receiving unit 8. In this case, the signal from the controller can be transmitted to the receiving unit even in a situation where it is difficult for the signal to reach the transmitting unit 11.
[0035]
Control means other than the above will be described.
FIG. 2A is a side view of the ejection device with a driving device according to the present invention in a case where the control means uses magnetic lines of force, and FIG. When this method is used, the material of the container body 1 is a non-magnetic material, for example, glass, synthetic resin, pottery and the like can be used. However, in view of pressure resistance and ease of molding, a magnetically permeable metal such as aluminum is used. Preferably, it is formed. As shown in FIG. 2A, an operation piece 20a provided with a permanent magnet 20 and a shoulder cover for holding the operation piece 20a slidably in the left-right direction along the shoulder are provided on the outside of the shoulder of the container body 1. A control box 21 is provided. The entire operation piece 20a may be a permanent magnet. A reed switch 22 is provided directly behind the control box 21, that is, inside the container body 1. As shown in FIG. 3A, an N-pole and an S-pole are induced at the contact portion by the permanent magnet 20 as shown in FIG. 3A, and the circuit (contact) is closed and turned ON by the magnetic attraction.
[0036]
When the permanent magnet 20 moves from the contact portion of the reed switch 22 as shown in FIG. 3B, the magnetic field is removed and the contact is opened by the resilience of the lead, and the circuit is opened, so that the circuit is turned off. The ON / OFF state is transmitted as a signal to the electromagnetic valve 6 by a cord 10 provided between the electromagnetic valve 6 and the reed switch, and when the injection button 5 is held in a depressed state, the ON signal Is transmitted from the nozzle of the ejection button 5 at the time when is transmitted to the solenoid valve. In addition, the injection of the contents is stopped by setting the above-mentioned OFF state.
[0037]
FIGS. 4 to 8 show an aerosol device A which employs, as a control means, a sensor provided in the container 3 for detecting the attitude of the container. These can control the driving device from the outside by shaking, tilting or inverting the container 3. The aerosol apparatus A shown in FIG. 4 has a steel ball 31 stored in the container 3 in an idle state, and a sensor S for detecting that the steel ball 31 has contacted or collided with the electromagnetic valve 6 as a driving means is provided. is there.
[0038]
When this is used, the user shakes the container 3 and brings the steel ball 31 into contact with or hits the electromagnetic valve 6. Then, the sensor transmits an ON signal by the contact or collision, and the electromagnetic valve 6 is turned ON by the signal to start injection. To turn off the solenoid valve 6, for example, it may be turned off by a timer when a certain time has elapsed from the start of injection, or may be turned off again when the sensor detects contact or collision with a steel ball. .
[0039]
In the aerosol apparatus A shown in FIG. 5, a dip tube 41 is connected below the solenoid valve 6, and an appropriate weight 42 is attached below the dip tube 41. The weight 42 includes a metal ring 43 that is a conductive member and a rubber 44 that is a non-conductive member provided below the metal ring 43. A battery is attached to the solenoid valve 6. The inner surface of the container body 1 is connected to the positive electrode of the battery, and the metal ring 43 is connected to the negative electrode. The solenoid valve 6 is provided with an amplification circuit that amplifies the energization of the container body 1 and the metal ring 43 to operate the solenoid valve.
[0040]
When this is used, the user tilts the aerosol device A to bring the metal ring 43 into contact with the inner surface of the container body 1. Then, the container body 1 and the metal ring 43 are energized by this contact, and the current caused by the energization is amplified by the amplifier circuit to turn on the solenoid valve. As a result, the solenoid valve 6 is opened, and the contents are ejected. To turn off the solenoid valve 6, the container body 1 is erected and the metal ring 43 is separated from the inner surface of the container body 1. However, as in the above-described embodiment, the sensor may be turned off by a timer or may be turned off when the sensor detects the contact between the metal ring 43 and the inner surface of the container body 1 again after the energization is once stopped. . When the container 3 is in the upright state, the synthetic rubber 44 is in contact with the bottom surface to prevent the metal ring 43 from contacting, so that accidental energization is prevented. Further, when the container is used while being gripped, it is preferable that the outer surface of the container body 1 be covered with an insulating material such as rubber so as not to be discharged to the human body from the gripped hand.
[0041]
The aerosol device A shown in FIG. 6A has a solenoid valve 6 provided on the lower surface of the housing. As shown in FIG. 6B, the electromagnetic valve 6 is provided with a sensor S for detecting the inclination of the dip tube 41, and the base end of the dip tube 41 is connected thereto. The tip of the dip tube 41 is provided with a weight 42 for facilitating the dip tube 41 to incline in the same direction when the aerosol device A is inclined.
[0042]
When using this, the user tilts the container 3. At this time, the dip tube 41 also tilts as shown in FIG. 6C, but at the same time, the base end thereof touches the sensor S, detects the tilt of the dip tube 41, and sends an ON signal to the solenoid valve 6. When the solenoid valve 6 is turned ON by the signal, the contents are ejected. To turn off the solenoid valve, the container 3 is returned to the upright state as shown in FIG. 6B, and the inclination of the dip tube 41 is returned to the original state. Thereby, the base end of the dip tube 41 is brought into a non-contact state with the sensor S and turned off. Further, a timer may be provided so as to be turned off after a certain period of time as in the above embodiment.
[0043]
The aerosol device of FIG. 7 is suspended from the upper part of the container body 1 in the container 3, a weight 51 is provided at the tip of the flexible dip tube 41, and a sensor for detecting the connection with the weight 51 is provided in the solenoid valve 6. And a circuit for operating the electromagnetic valve 6 based on the detection of the sensor.
[0044]
Therefore, when the container A is in the inverted state, the weight 51 contacts the lower surface of the solenoid valve 6 as shown in FIG. In the inverted state, since the liquid phase of the contents comes to the lower side, the tip of the dip tube 41 is immersed in the liquid phase, and the gas phase is not released. However, the weight 51 may be hung by a flexible rim or the like without using the dip tube. The solenoid valve is closed by returning to the upright position.
[0045]
8 has a ball-shaped weight 63 provided in a bottomed cylinder 62 provided on the lower surface of the solenoid valve 6. Also in this device, the electromagnetic valve 6 operates when a sensor provided in the electromagnetic valve detects that the aerosol device has been inverted.
[0046]
As described above, when each of the containers 3 shown in FIGS. 7 and 8 is in an inverted state, the solenoid valve receives the ON signal and starts jetting the contents. Also, by returning to the upright state, the solenoid valve receives the OFF signal, and the ejection of the contents is stopped.
[0047]
Next, the operation of the solenoid valve 6 will be described.
It is more effective to use a solenoid valve that can perform various operations depending on the type of the ON signal of the control means. For example, adjusting the opening time of the valve to change the discharge amount to a fixed amount, a large amount, a minute amount, adjusting the opening degree of the valve to change the temporary discharge amount or discharge force, and repeatedly opening and closing the valve at regular intervals Such adjustment can be made so that discharge can be performed intermittently. A plurality of solenoid valves may be provided so that the solenoid valve to be opened can be selected so that the contents to be discharged can be selected. In this case, different types of contents may be stored separately (see FIG. 10A).

An embodiment of the driving device of the aerosol device A shown in FIG. 9 includes a stirring member 73 used for homogenizing the contents of the container body 1 or stirring the sediment, and a motor 72 for driving the stirring member. Become. The motor 72 is provided below the housing 12. The stirring member 73 is configured by providing a stirring blade 75 on the outer periphery of a relatively hard dip tube 74, and the dip tube 74 is rotatably provided with respect to the housing 12.
[0049]
In this case, for example, the container body 1 is a transparent body through which visible light or the like is transmitted, and a signal of visible light from the outside of the container A is received by a sensor provided in the motor 72 to enable the operation of the stirring member 73. . Such a stirring member 73 is useful for an aerosol product filled with contents to be separated when the contents to be jetted include powder, or when the contents to be separated are placed such as an aqueous liquid and an oily liquid.
[0050]
The aerosol device A shown in FIG. 10A includes a driving device including a stirring blade stem 82 used to stir the contents introduced into the housing 12 and a motor 81 for driving the stem. More specifically, an inner bag 91 in which the two liquids (the liquid A and the liquid B) are separately stored in the container body 1 is provided, and the stirring is performed when the two liquids are mixed in the housing. The wing stem 82 and the motor 81 constitute a driving device. The upper storage portion of the inner bag 91 communicates with the inside of the housing 12 through a communication hole 12 d formed in the housing 12. The lower storage portion communicates with the inside of the housing 12 through a dip tube 89 provided with a gap between the lower storage portion and the stirring blade stem 82. The motor 81 is provided on the bottom surface of the container body 1, and the distal end of a stem 90 penetrating through a housing pilot hole 12c (shown in FIG. 9B) is connected to the motor 81. However, they are connected slidably in the axial direction and capable of transmitting torque so that there is no problem even if the injection button 5 is pressed to lower the stem when the stem is rotated. Reference numeral 92 denotes a sealing material.
[0051]
The motor 81 shown in FIG. 10A operates using magnetic lines of force similar to that shown in FIG. 3. A permanent magnet 83 is provided outside the lower portion of the container body 1 and a reed switch 84 is provided inside the same. The reed switch 84 and the motor 81 are connected by a cord, and can be controlled by an ON / OFF signal. As shown in FIGS. 10B and 10C, the stirring blade stem 82 has a flange 86 in contact with the stem gasket 85 in the housing 12, a stirring blade 87 on the lower surface of the flange 86, and a space between the adjacent stirring blades 87. It has a spring 88 vertically provided between the flange and the bottom surface of the housing. In the case of the aerosol product shown in FIG. 10, a motor can be provided below the valve housing 12 as shown in FIG.
[0052]
The operation of this device allows the stem 90 to reciprocate by closing the circuit of the reed switch 84 by either rotating the container 3 or moving the magnet 83. On the other hand, the ejection button 5 is maintained in a state in which the contents are ejected, as described above. Therefore, when the circuit of the limit switch 84 is closed and set to the ON state, the two liquids in the container 3 are mixed in the housing 12 and are ejected. When the injection is to be stopped, the previous circuit may be opened to turn off the circuit.
[0053]
By the way, as the container 3 for rotating the stem, as shown in FIG. 11, the tip of the stem (the one with the nozzle facing the top) is covered with the ejection button 94 having an arbitrary number of ejection ports 93 as shown in FIG. Is preferred. By rotating the stem in the manner described above, the spray button 94 also rotates at the same time, so that the spray surrounding the container 3 is sprayed. For example, when this is installed in a room, the contents can be widely spread throughout the room. In addition, in this embodiment, it is suitably used for spraying contents such as an indoor insecticide, deodorant, and fragrance.
[0054]
As shown in FIG. 11, in a discharge device provided with a driving device for rotating or reciprocating the ejection button 93, the ejection button is pressed down and rotated somewhat to engage the shoulder cover 21, as shown in FIG. 1 or FIG. By doing so, a mechanism for maintaining the pressed state cannot be employed as it is. Therefore, for example, as shown in FIG. 12, the rotating ejection member 95 and the engagement operation member (push button) 96 are separately configured, and the ejection member 95 and the stem 90 are free with the engagement operation member 96 pressed down. The engagement operation member 96 is not affected even if the ejection member 95 rotates. With this configuration, it is possible to achieve both rotation and maintenance of the depressed state.
[0055]
In the discharge device 3 for stirring and mixing the contents in the valve housing 12 shown in FIGS. 10A to 10C, a spring 88 for urging the stirring blade stem 82 upward is provided between the stirring blades 87. Although it is necessary to rotate the reciprocating roller 82, as shown in FIG. 13, when the stirring blade 87 and the spring 88 are displaced in the vertical direction, they can be continuously rotated in one direction.
[0056]
The above-mentioned various solenoid valves, a stirring mechanism or a driving device such as a rotation of an injection button can be used alone, but a plurality of the same types may be combined or two or more different types of driving devices may be used in combination. You can also. For example, in the case of a discharge device in which the stirring mechanism shown in FIGS. 9 and 10 is provided in the container body or the valve housing, an electromagnetic valve may be provided as a driving device in addition to the stirring mechanism. In the case of FIG. 9, for example, an electromagnetic valve can be interposed between the valve housing 12 and the motor 72, or in the middle or at the lower end of the dip tube 74. When the electromagnetic valve is provided at the lower end of the dip tube 74, it is preferable that the solenoid valve be fixed to the bottom surface of the container body 1 and rotatably fitted to the lower end of the dip tube 74.
[0057]
In the case of the discharge device shown in FIG. 10, an electromagnetic valve is provided at the lower portion of the housing 12 shown in FIG. 10B, and the housing pilot hole 12c and the communication hole 12d are simultaneously opened and closed, and the flow rate is increased or decreased. Alternatively, two inner bags may be provided in parallel, and a solenoid valve may be interposed between each inner bag and the housing. In that case, the dip tube may be inserted into each inner bag or may be omitted. The stirring stem may be driven to rotate by a motor provided at the lower part of the valve housing 12 as shown in FIG. 9, or may be driven via a shaft or the like by a motor disposed at the bottom of the container body as shown in FIG. Good.
[0058]
In the case of an aerosol product provided with a mixing and stirring mechanism and an electromagnetic valve as described above, for example, if the push button is kept pressed down by a mechanism as shown in FIG. The mixed contents can be set so as to be discharged in a desired discharge amount and discharge state. The start of the stirring mechanism and the start of the discharge may be simultaneous. However, if the discharge is performed after stirring and mixing for a certain period of time, the two liquids that have been sufficiently mixed can be discharged.
[0059]
In the case of an aerosol product that rotates the ejection button as shown in FIG. 11, a solenoid valve and a rotation mechanism are provided as a driving device, and the ejection button is maintained in a rotatable state and in a depressed state. When the ON signal is issued by the means, the contents can be set to be sprayed over a wide range with a desired spray amount and spray state while the spray button rotates.
[0060]
When a plurality of drive devices are provided, individual control means can be provided for each drive device, but it is preferable to provide control means capable of emitting two or more types of signals. For example, a transmitter that uses control means having a signal path of two or more channels, or a transmitter that transmits a plurality of types of numerical data by a pulse signal of light or ultrasonic waves, such as a remote control device of a television or an air conditioner, and separates the signal. A combination with a receiver that receives separately is preferable. Thereby, the solenoid valve and the rotation motor can be individually controlled.
[0061]
When the injection button is kept depressed and the control means first issues a motor ON signal, the contents are agitated by the agitating member and uniformly mixed, and then the solenoid valve 6 is operated by the control means. For example, by switching the operation buttons of the control means and selecting an appropriate signal, the discharge state of the contents can be made as desired.
