Description

  The present invention relates to an aerosol-type disinfectant / deodorant composition mainly containing a stabilized chlorine dioxide solution and an aerosol-type jetting device filled with the composition.

  In the meat and fish market, etc., bacteria are easy to propagate due to the nature of the foods handled, so it is necessary to sterilize and disinfect from the viewpoint of hygiene and safety. Moreover, in general, bathtubs in inns and health lands use circulating water from the viewpoint of cost. This circulating water is easy for bacteria to propagate, and there are many cases where bathers have been infected with bacteria recently, and the circulating water is sterilized. Furthermore, since food companies and hospital kitchens handle various foods, it is necessary to perform disinfection from the viewpoint of food poisoning prevention and hygiene management.

  Conventionally, a stabilized chlorine dioxide solution (chlorite aqueous solution) has been used as this type of disinfectant. This utilizes the disinfection / bactericidal effect of pathogenic microorganisms of chlorine dioxide, the prevention of bacterial infectious diseases, the deodorizing effect, and the like.

  When sterilizing with a stabilized chlorine dioxide solution in the meat, fish market, etc., a large spray facility such as a splicer is necessary. In addition to this, the concentration control of the stabilized chlorine dioxide solution and the activator Special knowledge such as addition and technology are required.

  The same applies to disinfection of hospitals and other kitchens.

  In order to sterilize circulating water such as inns and health lands, a large-scale chlorine dioxide generator that adds an activator is required.

  Therefore, there has been a problem that none of these can be easily used and applied by ordinary daily residents.

  As a simple one that can be obtained by a general consumer, a spray method using a small resin-made simple pump or the like can be considered.

  However, stabilized chlorine dioxide solution has the property of generating chlorine dioxide gas when it reacts with light or when it comes into contact with carbon dioxide in the air. Risk of contact with gas. Therefore, during long-term storage, the reaction that generates chlorine dioxide as an active ingredient from the stabilized chlorine dioxide solution continues by reaction with carbon dioxide, and the effective chlorine dioxide concentration of the stabilized chlorine dioxide solution decreases. There is a problem that the effect of the decrease.

  After all, there are no disinfectants and devices that can be easily used by general consumers, have good storage stability, can be used safely, can be made compact, can be carried around every day, and can be used as needed.

  The present invention has been proposed in view of the above, and the object of the present invention is to enable stabilized chlorine dioxide solution, which has been limited to the handling of specialists in the past, to be packaged as an aerosol type and stored. A disinfectant / deodorant composition that has excellent stability, can be packaged in an aerosol form, can be carried, and can be used easily and safely by anyone without the need for specialized knowledge and technology, and An object of the present invention is to provide an aerosol ejection device filled with the composition.

  Embodiments of the present invention will be described below with reference to the drawings.

[Embodiment 1]
Fig.1 (a) is a schematic sectional drawing of the aerosol-type ejection apparatus concerning one Example of this invention, The figure (b) shows the ratio of the filling material filled.

  In FIG. 1A, reference numeral 1 denotes a sealed container that does not transmit light, and includes a bottomed cylindrical container body 1a and a reverse funnel-shaped upper part 1b that is integrally provided thereabove. A push button type aerosol valve device 3 for injecting the atomized filler to the outside is provided at the center of the upper portion 1b. The aerosol valve device 3 includes a push button 6 having a nozzle 5, a valve 7 positioned in the container 1, and the like.

  As the material of the container 1, aluminum is used from the viewpoint of preventing the corrosiveness by the filling 2 composed of the stabilized chlorine dioxide liquid 2a and the liquefied dimethyl ether 2b filled therein.

  Although the upper part 1b is integrally formed with the container main body 1a in advance, the container 1 may be formed by integrating a separate canopy. The shape of the container 1 is not limited to the illustrated example.

  The inner surface of the container 1 is preferably coated with a corrosion-resistant resin 4 such as epoxy polyamideimide.

  As described above, the container 1 is formed of aluminum and the inner surface thereof is coated with the corrosion-resistant resin 4, thereby providing sufficient durability over time with respect to the stabilized chlorine dioxide liquid 2 a and liquefied dimethyl ether 2 b filled therein. Can be secured.

  The proportion of the stabilized chlorine dioxide solution 2a for sterilization and deodorization filled in the container 1 and the liquefied dimethyl ether 2b as a propellant is 60 to 40 vol% for the liquefied dimethyl ether 2b and 40 to 60 vol for the stabilized chlorine dioxide solution 2a. It is filled in the range of%.

  The effective chlorine dioxide concentration of the stabilized chlorine dioxide solution 2a is set to 100 ppm to 500 ppm. In other words, if it is 500 ppm or more, an erosion-type corrosion tendency appears on the aluminum that is the material of the container 1, and an adverse effect on the human body becomes strong. This is because if it is 100 ppm or less, a sufficient effect as sterilization and deodorization cannot be obtained.

  Furthermore, the liquidity of the stabilized chlorine dioxide solution 2a is in the neutral range of pH 5-8. When the pH is 5 or less, it is difficult to maintain the storage stability of the stock solution itself, and the corrosion resistance to the aluminum container 1 is lowered after the stock solution is filled. When the pH is 8 or more, the storage stability of the undiluted solution itself is increased as opposed to when the pH is 5 or less, but because of the stability, generation of chlorine dioxide after spraying is slow, the expected effect cannot be obtained, and the aluminum container 1 has corrosion resistance. This is because of a decrease.

  Therefore, in the present invention, the pH is in the range of 5 to 8, thereby maintaining the storage stability of the stock solution itself, enhancing the aging durability of the aluminum container 1, and promoting the generation of appropriate and effective chlorine dioxide during use. Is possible.

  This is because liquefied dimethyl ether 2b is used as a propellant, but when liquefied dimethyl ether 2b is used, the stability of the stabilized chlorine dioxide liquid 2a can be maintained, and the mist can be refined during injection.

  Other aerosol propellants include carbon dioxide and liquefied petroleum gas. Of these, the carbon dioxide gas reacts with the stabilized chlorine dioxide solution 2a to promote the generation of chlorine dioxide gas, so that the storage stability is impaired. Since the liquefied petroleum gas has low compatibility with the stabilized chlorine dioxide liquid 2a and is separated, it is not suitable for atomizing the mist.

  In contrast, liquefied dimethyl ether 2b was confirmed to show no change in effective chlorine dioxide concentration over time as a result of a aging test, and can be stored for a long time in a stable state.

  As a method of atomizing the mist, there is a method of increasing the compatibility with the liquefied dimethyl ether 2b which is a propellant by adding an alcohol, a surfactant or the like to the stabilized chlorine dioxide solution 2a. However, the reaction with the stabilized chlorine dioxide solution 2a is impossible. Therefore, in the present invention, only liquefied dimethyl ether 2b is used, and no additive is used. Accordingly, the manufacturing is easy and the cost is not increased accordingly.

  The container 1 is filled with 60 to 40 vol% of liquefied dimethyl ether 2b and 40 to 60 vol% of the stabilized chlorine dioxide solution 2a. As shown in FIG. 1 (a), one of 40 to 60 vol% of liquefied dimethyl ether is used. A part is melt | dissolved in the stabilized chlorine dioxide liquid 2a, and one part is isolate | separated in the state of the supersaturated liquid dimethyl ether 2c.

  FIG. 2 shows an example of the basic structure of the main part of the aerosol valve device 3, and the illustration of the push button 6 and the like in FIG.

  One end of a spring 8 is locked in a housing 7 made of a resin molded product, and the other end of the spring 8 is locked to a lower portion of a stem 9, and the stem 9 is connected to the push button 6 shown in FIG. Is lowered against the spring force of the spring 8, and when the push-down force is released, the spring 8 is moved upward and returned.

  In the stem 9, a hole 9a for leading the filler 2 in the container 1 to the outside is formed in the axial direction, and a stem orifice 9b is formed in the lower part in a direction perpendicular to the hole 9a. The stem orifice 9b is normally closed by a stem rubber 10 provided on the outer periphery of the stem orifice 9b. When the stem 9 is moved downward, the stem orifice 9b is positioned in the hollow chamber 7c in the valve 7, and the inside of the container 1 and the stem 9 are The hole 9a communicates with the hole 9a.

  A vapor tap orifice 7a of 0.4 mm or more communicating with the hollow chamber 7c is formed on the side of the valve 7, and 1.0 mm or less communicating with the inside of the hollow chamber 7c and the container 1 is formed in the lower portion of the valve 7. A main orifice 7 b is formed, and the valve 7 is connected to the tube 11. When the stem 9 is pushed down, the mist-like filling 2 is ejected from the nozzle 5 shown in FIG. 1A to the outside through the stem orifice 9b and the hole 9a through the main orifice 7b and the vapor tap orifice 7a. Is configured to do.

  That is, when the push button 6 of the aerosol valve device 3 is pushed down, as shown in FIG. 3, the filler 2 passes through the tube 11 and enters the valve 7, and the supersaturated liquefied dimethyl ether 2c is vaporized and indicated by a broken line. As described above, the gas is introduced into the housing 7 through the vapor tap orifice 7a and into the hollow chamber 7c, and is sprayed to the outside through the stem orifice 9b and the hole 9a.

  The supersaturated liquefied dimethyl ether 2c keeps the internal pressure of the container 1 constant from the start of use until it is used up, and as shown in FIG. 4, even if the packing 2 decreases with use, the constant injection force and constant particle diameter are maintained. It is possible to secure it until it is used up.

  And as shown in FIG. 5, it lose | disappears just before using up and only liquefied dimethyl ether 2b is not injected. Since the container 1 is empty after it has been used up, the disposal of the container 1 is easy.

  The average particle size of the fine particles thus obtained is 30 μm to 40 μm. The average sprayed particle diameter of a general aerosol using liquefied petroleum gas is 100 μm to 200 μm, and the average particle diameter of a mist obtained by a manual pump is 200 μm to 300 μm. A mist 7 to 8 times finer than the pump is obtained.

  This finely divided aerosol spray makes it possible to generate a trace amount of chlorine dioxide, which can exert a sufficient effect.

  As described above, in the present invention, the stabilized chlorine dioxide solution 2a and the liquefied dimethyl ether 2b are filled at a predetermined ratio, and the valve 7 having the vapor tap orifice 7a and the main orifice 7b having a predetermined diameter is used. The generation of trace amounts of chlorine dioxide was accelerated compared to conventional aerosol formulations and manual pumps.

  The experimental method and results are shown below.
