Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to aerosol products. More specifically, the present invention relates to an aerosol product capable of generating an electric charge by shaking a product or the like and injecting an aerosol composition together with the generated electric charge.
[0002]
[Prior art]
In general, aerosol products are filled with an aerosol composition consisting of a stock solution and a propellant in an aerosol container. In the case of a spray type product, the stock solution is made into a fine mist by volume expansion due to vaporization of the propellant (liquefied gas). Thus, it can be sprayed evenly and broadly on the object. Its uses are for hair products such as hair spray and treatment spray, skin products such as anti-inflammatory analgesic spray and disinfection spray, space products such as insecticide spray and deodorant spray, and household products such as dust blow, paint and lubrication spray.・ Various products such as industrial and automotive products.
[0003]
On the other hand, in recent years, attention has been focused on electrically charged fluids such as air ions and ionized water, and various products related to them have been produced.
[0004]
The air ion refers to positively or negatively charged fine particles (such as oxygen molecules) in a gas. Positively charged particles are referred to as positive ions, and negatively charged particles are referred to as negative ions. As a general principle of generation, free electrons are emitted into the air, which collide with and adhere to other gas molecules and are generated. As a method of generating positive ions using these principles, corona discharge, which is an electric generation method, is known. Methods of generating negative ions include generation by the Leonard effect, generation by trace radiation, and electric generation (corona discharge). In addition, a method of generating energy by applying external energy such as rubbing tourmaline or applying heat It has been known.
[0005]
These air ions are produced and sold in products such as air conditioners and air purifiers for the purpose of removing static electricity, removing dust, and providing antibacterial effects. In addition, negative ions have been shown to have an effect on the living body, in particular, recovery from fatigue (neutralization of lactate), relaxation, and alleviation and healing of various disease symptoms. ing.
[0006]
Further, ionized water is divided into alkali ionized water and acidic ionized water, and is generally generated by electrolysis of water. Alkaline ionized water is used as drinking water for good health, and acidic ionized water is used as disinfecting water, lotion, etc., and is widely used in homes and the like.
[0007]
[Problems to be solved by the invention]
However, a special device for generating ions is required to obtain the effect of the ions. In the case of an aerosol product, when the aerosol composition is vigorously circulated through a narrow passage such as a long tube, the aerosol composition is charged (see Patent No. 2628274). The effect of ionized water cannot be obtained much.
[0008]
An object of the present invention is to provide an aerosol product that can generate an electric charge by a simple method and spray an aerosol composition together with the generated electric charge.
[0009]
[Means for Solving the Problems]
The aerosol product of the present invention comprises an aerosol container comprising a container body and an aerosol valve fixed to an opening of the container body, an aerosol composition filled inside the aerosol container, and an injection hole mounted on the aerosol valve. And an injection member having an injection passage communicating the injection hole with the aerosol valve, and a charge holding unit capable of generating charges and storing the generated charges. The unit is characterized in that it is configured to be able to conduct electricity so that the electric charge accumulated in the electric charge holding unit and the jetted aerosol composition can be charged to the injection hole and / or the injection passage of the injection member. (Claim 1). In addition, it is preferable that such an aerosol product is provided with a unit in which the charge holding unit generates a charge by any of contact charge, friction charge, peeling charge, and impact charge (Claim 2). Further, the charge holding unit includes a powder and a cavity for accommodating the powder, and the powder contacts each other and / or the powder and the inner surface of the cavity by contact, friction or collision in the cavity. Is preferably charged (claim 3). Further, it is preferable that the charge holding portion is formed of a hollow portion whose inner surface is covered with a conductive member and a non-conductive member, and powder contained in the hollow portion (claim 4). It is preferable to provide a moving member capable of moving the outer peripheral surface while contacting at least a part of the outer peripheral surface (claim 5). Further, it is preferable that the outer surface of the charge holding portion is formed of a non-conductive member.
[0010]
[Action and effect of the invention]
The aerosol product of the present invention (Claim 1) is provided with a charge holding portion capable of generating charge and storing the generated charge, so that the generated charge is not released to the outside and a large amount of charge can be stored. .
[0011]
In addition, since the charge holding unit and the injection holes and / or the injection passages can be energized, the accumulated charge is easily applied to the aerosol composition flowing through the injection holes or the injection passages when the aerosol composition is injected. As a result, the charge amount of the aerosol composition injected from the injection hole increases, and the effect of an electrically charged fluid such as air ions or ionized water is easily obtained. Further, when the means for generating electric charges is any of contact charging, frictional charging, peeling charging, and collision charging, the electric charges can be generated by a simple configuration or method (claim 2).
[0012]
In a case where the charge holding unit includes a powder and a cavity for accommodating the powder (claim 3), the powders and the powder and the inner surface of the cavity contact, friction, or collide in the cavity. As a result, the powder is charged, and the generated charge is accumulated on the powder and the inner surface of the cavity. That is, charges can be generated by a simple operation such as shaking the aerosol product. In the case where the charge holding portion has a cavity whose inner surface is covered with a conductive member and a non-conductive member, and the cavity contains powder, the charged powder is charged. Is electrically attracted to and adheres to the conductive member, but when the electric charge is released, it separates from the conductive member and accumulates in the non-conductive member. It can be visually confirmed whether or not the electric charge is held.
[0013]
In the case where the charge holding unit includes a moving member that moves on the outer peripheral surface while being in contact with at least a part of the outer peripheral surface of the injection passage (claim 5), the moving member moves on the outer peripheral surface, thereby causing friction. The outer peripheral surface and the moving member are charged. That is, the charge can be charged by a simple action performed before use, such as shaking the aerosol product. In addition, since the aerosol composition can accumulate on the outer peripheral surface of the injection passage, it is easy to apply a charge to the aerosol composition.
[0014]
In the case where the outer surface of the charge holding portion is formed of a non-conductive member (claim 6), the finger to be operated is prevented from coming into contact with the portion storing the charge, for example, when operating the ejection member. Therefore, it is possible to prevent the accumulated charge from flowing from the contacted finger to the human body, further from the human body to the ground, and releasing the charge.
[0015]

[0016]
An aerosol product 1 shown in FIG. 1A has a bottomed pressure-resistant container body 2, an aerosol valve 3 (hereinafter simply referred to as a valve) fixed to an upper opening of the container body 2, and a valve 3. It has an ejecting member 4 attached, and a cap 5 covering the valve 3 and the ejecting member 4 and having a charge holding portion 10.
[0017]
The container body 2 is a conventionally known one, and a body plate 6 is formed by drawing and ironing a metal plate such as aluminum or tin plate into, for example, a cylindrical shape with a bottom, and forming a shoulder portion 7 and a neck portion on the upper portion thereof by necking or the like. The bead 8 is formed at the upper end of the neck by curling. Other materials such as synthetic resin such as polyethylene terephthalate and glass can also be used.
[0018]
The valve 3 is, for example, as shown in FIG. 9, a mounting cup B crimped on a bead 8 of a container body, a housing C held at the center of the mounting cup B, and a vertically movable housing housed in the housing C. And a dip tube H extending from the lower end of the housing C to the bottom of the container body.

Be released. At this time, the aerosol composition filled in the aerosol container 2 is introduced from the dip tube H into the housing C, and further passes through the stem D, the stem insertion opening 11 and the injection passage 9 to be injected from the injection hole 12 to the outside. Is done. Note that the injection holes 12 and / or the injection passages 9 are used to easily charge the electric charge accumulated in the charge holding unit 10 described later to the aerosol composition passing through the injection holes or the injection passages when the aerosol composition is injected. Preferably, the conductive material is made of a conductive material having excellent conductivity, such as a metal such as aluminum, tin, iron, stainless steel, and copper. In this case, it is preferable that the charge holding unit 10 and the injection hole 12 and / or the injection passage 9 are in contact with each other and are electrically connected. On the other hand, the injection member 4 is made of a synthetic resin such as Duracon, nylon, polyethylene, or polyethylene terephthalate in order to prevent the electric charge accumulated during the injection operation from flowing from the operated finger to the human body and from the human body to the ground and not being discharged. It is preferable to use a material having low conductivity or to coat the outer surface of the injection member with an insulator such as a rubber such as nitrile rubber, styrene butadiene rubber, chloroprene rubber, butyl rubber, or silicone rubber, an elastomer, or cork. In this embodiment, a metal chip 12a having an injection hole is mounted on the injection member, and the chip 12a and the charge holding unit 10 come into contact with each other and can be energized.
[0020]

Note that an aerosol composition that can be sprayed in the form of a mist is preferable because the charge accumulated in the charge holding portion is easily ejected to the outside, and the effect of the charge is easily obtained.
[0021]
The cap 5 has a bottomed cylindrical cap body 5a detachably mounted on the periphery of the valve 3 crimped on the bead 8 of the container body, and a cap mounted on the cap body to form a cavity between the cap body. It is composed of a mounting part 10a and a powder 10b further housed in the hollow part.
[0022]
The cap main body 5a is made of a non-conductive material such as the above-described synthetic resin, and cuts off electricity between the charge holding unit 10 and the aerosol container 2, and transfers the charges accumulated in the charge holding unit 10 to the aerosol container 2. Further, it is prevented from being released to a person or the ground through the aerosol container 2.
[0023]
The cap mounting portion 10a is made of a conductive material such as the above-described metal as shown in FIG. 1B, and has an outer surface 10c exposed to the outside when mounted on the cap body 5a, such as silicone rubber or synthetic rubber. Covered with insulator. Note that the cap mounting portion 10a may be formed of the same non-conductive material as the cap body 5a such as a synthetic resin, and the inner surface 10d of the cavity may be covered with a conductor such as a metal.
Further, the cap mounting portion 10a includes a tongue piece 13 having conductivity so as to be able to conduct electricity with the tip 12a mounted on the jetting member, and the tongue piece 13 is provided with the cap 5 mounted on the aerosol container 2. When it is in contact with the chip 12a, the charge of the charge holding unit 10 can be applied to the chip 12a.
The powder 10b may be a powder that is easily negatively charged such as cellulose acetate, Teflon (registered trademark of DuPont), vinyl chloride, cellophane, celluloid, polyethylene, polypropylene, carbide, polystyrene, asbestos, glass, mica, nylon, acrylic It can be appropriately selected according to the kind of the charge to be charged, from powders which are easily positively charged, such as metal powders such as aluminum, iron, copper, and nickel, in consideration of the material of the inner surface of the cavity.
[0024]
In the present embodiment, the cap 10 containing the powder 10b in the cavity is shaken with the cap 5 attached to the aerosol container 2, so that the powders 10b or the powder 10b and the inner surface 10d of the cavity contact or collide with each other. Alternatively, the powder 10b and the inner surface 10d of the cavity are charged by the collision or the friction, and the charge is accumulated in the charge holding unit 10. Thereby, when the cap 5 is equipped, the electric charge is accumulated in the electric charge holding unit 10 by shaking the aerosol product 1 and at the same time, the electric charge charges the injection hole 12 through the tongue 13 by the electrostatic induction. it can. Alternatively, the charge holding unit 10 may be charged by shaking only the cap 5, and then the cap 5 may be placed on the aerosol container 2 to charge the injection holes 12.
[0025]
Further, in this embodiment, since the inner surface 10d of the hollow portion is formed of a conductive member (cap mounting portion) and a non-conductive member (cap body), the powder is electrically bonded to the conductive member when the electric charge of the powder is lost. Since the powder is peeled off and accumulated on the non-conductive member, the presence or absence of electric charge can be visually confirmed.
[0026]
After charging the injection holes 12, the cap 5 is removed and the injection member 4 is pushed down as described above, so that the aerosol composition is injected from the charged injection holes 12 through the injection passage 9. When passing through the injection hole 12, the atomized spray ejected from the injection hole 12 comes into contact with the charged tip 12a of the injection hole 12, and the electric charge accumulated in the injection hole 12 is applied to the spray. As a result, the jet is charged. Then, the charged mist-like spray is ejected and diffused. In addition to the effect of the active ingredient blended in the aerosol composition, the charged mist-like squirt was charged to the same potential as the charge elimination effect on clothing, curtains, glass, machinery, hair, human body, etc. The aerosol composition (active ingredient) is selectively adhered by utilizing the diffusion effect due to the repulsion of particles, the electrical properties of the object to be ejected such as clothing, curtains, glass, machinery, hair, human body, and even pests. It has effects such as. After use, the charges of the charge generation unit 10 and the powder 10b are discharged spontaneously even if left unattended, but may be positively discharged, for example, by grounding the tongue piece 13. Further, by opening and closing the charge holding unit 10, the charge holding unit 10 may be opened after use to discharge the powder 10b therein.
[0027]
FIG. 2a shows another embodiment of the aerosol product of the present invention. The aerosol product 20 shown in FIG. 2a includes an injection member 21 mounted on a valve, and a cover member 22 engaged with the valve mounting portion of the aerosol container. The injection member 21 includes an injection hole 23, a stem insertion port 24 into which the stem D is inserted, and an injection passage 25, similarly to the aerosol product 1 of FIG. 1 described above.
[0028]
The cover member 22 is rotatable between a base 26 that engages with a valve mounting portion, side walls 27 provided on both sides of the base 26 so as to surround both sides of the injection member 21, and a side wall 27. And a switching unit 29 also serving as a cover. The side wall portion 27 is provided with a charge holding portion 28 for generating and holding substantially the same charge as that shown in FIG. 1B. The switching unit 29 operates to energize / cut off the electrical connection between the charge holding unit 28 and the injection hole 23 of the injection member 21.

The switching portion 29 includes a plate-shaped main body 29a, a shaft portion 29b protruding from the main body 29a, and a locking portion 29c protruding left and right from the other end. A bearing portion 27a for rotatably supporting the shaft portion 29b of the switching portion 29 is formed on the inner surface of the upper portion of the front end of the side wall portion 29, and the locking portion 29c is locked upward at the upper portion of the rear end. Locking step 27b is provided. Thereby, the switching unit 29 is rotatable between an energizing position where it contacts the front surface of the ejection member 21 and a blocking position where the switching portion 29 is turned outward and upward from the position to cover the ejection member 21. Become. Further, the main body 29a of the switching unit 29 has a portion 23a that is in electrical contact with the periphery of the injection hole 23, and does not block an ejected material ejected from the ejection hole 23 when the ejection member 21 is pressed down. Is provided with an opening 23b. The opening 23b is vertically long so as to correspond to the vertical movement of the ejection member 21.

I let you know. Therefore, when the switching unit 29 is in the energized position as shown by the solid line in FIG. 2A, the charge holding unit 28 can communicate with the injection holes 23 via the switching unit 29. When the aerosol product is not used, the switching unit 29 is rotated to the blocking position as shown by the broken line. As a result, the charge holding unit 28 and the injection hole 23 are not electrically connected. In this case, since the switching unit 29 covers the upper part of the ejection member 21, it is possible to protect the ejection member 21 from being pressed down.
[0031]
In this embodiment, similarly to the above-described embodiment, before the injection operation is performed, the charge is first generated and accumulated in the charge holding unit 28 by shaking the aerosol product or the like, and then the switching unit 29 is set to the energized position and then injected. The member 21 is operated. At this time, the aerosol composition is injected from the injection hole 23 through the stem insertion port 24 of the injection member and the injection passage 25 from the stem D of the valve. Injected outside. The locking step 27b of the side wall 27 may be electrically connected to the container body. In that case, the charge remaining from the charge holding unit 28 can be discharged when the switching unit 29 is turned off and in the cutoff state. The switching section 29 does not need to be entirely made of a conductive material such as a metal, but may be entirely made of a non-conductive material such as a synthetic resin, and may be provided with an energized layer only at a necessary portion. Further, the charge holding unit 28 may be provided inside the switching unit 29. In this case, there is no need to supply electricity to the side wall 27 via the shaft 29b. Further, the charge holding unit 28 may be provided on both the switching unit 29 and the side wall unit 27. In the aerosol product 20 of FIG. 2A, the injection holes 23 are provided on the side surface (front surface) of the injection member 21, but may be provided on the upper surface. In this case, when the switching unit 29 is rotated to the upper surface side of the ejection member 21, the switching unit 29 is brought into contact with the ejection hole 23 to be in the energized state. And when it falls down, it will be in a cutoff state.

Further, a metal tube 37 a is used as a part of the injection passage 37, and the metal tube 37 a is in contact with the conductive member of the charge holding unit 35, so that it can be electrically connected to the charge holding unit 35. Therefore, when the aerosol composition flows through the metal tube 37a, the charge accumulated in the charge holding unit 35 is provided, and the charge can be ejected to the outside together with the aerosol composition.
Further, the aerosol product 30 may be provided with a nozzle 37b having an elongated metal tube as shown in FIG. 3B. As a result, the contact area between the aerosol composition and the metal tube increases, and more charge is imparted to the aerosol composition. In that case, it is preferable that the surface of the metal tube be covered with a non-conductive member so that the accumulated charge is not discharged by contact with the outside.

Thus, the aerosol composition is injected through the stem D through the stem insertion port 46a, the injection passage 46b, and the injection hole 46. The pressing portion 47 is a rectangular block, and the surface is covered with an insulator. In this embodiment, the charge holding section 45 is made of the same material as the stem insertion port 46a, the injection passage 46b, and the injection hole 46, and is connected via a hinge 47a. Therefore, the electric charge holding section 45 electrically supplies the electric current from the stem insertion port 46a to the injection passage 46b and the injection hole 46. Thereby, when performing the injection operation of pushing down the pressing portion 47, the aerosol composition is given a charge at any part from the stem insertion port 46a to the injection passage 46b and further to the injection hole 46, and the aerosol product 1 shown in FIG.

One end of the charge generation section 86 is a key section 87, which is fitted with the ejection member main body 82. The operation section 88 at the other end of the charge generation section 86 is covered with an insulator 89 (silicone rubber, synthetic rubber, or the like). In this embodiment, the operation section 88 is pinched with a finger, and the charge generation section 86 that is in close contact with the injection hole 85 is peeled off, so that separation charging can be performed. Therefore, electric charges are accumulated in the ejection holes 85 formed in the conductive chip. Thereby, by pushing down the ejection member 81 and performing the ejection operation, it is possible to apply electric charges to the aerosol composition ejected from the ejection holes 85. When not in use, since the injection hole 85 is covered, the charge generation section 86 also serves as a cover for the injection hole 85.
