Description

[Detailed description of the invention]

The present invention relates to an apparatus for guiding an active ingredient solution in an aerosol container to an application section installed on the side of the container, and causing it to ooze out from the application surface of the application section. In recent years, due to changes in the living environment or lifestyle, for example, furniture cleaners, antistatic agents for clothing, records, plastics, etc., antistatic agents, waterproofing agents for clothing, stain removers, softeners for leather products, polishing agents, etc. anti-mold agent for clothing, leather products,
Deodorizing products, flame retardants for curtains, wallpaper, etc., glass cleaners, anti-fog agents, anti-rust moisturizers for sliding doors, etc.
All types of liniments are used, including moisturizers for sewing, disinfectants and deodorizers for hospital rooms and hospital beds, pest repellents or insecticides for pet animals, hair care agents, parasitic insecticides for taxidermy, cleaning agents for carpets, etc. It became like that. Conventionally, hand pump type and aerosol spray type have been commonly used as coating devices, but these have the following drawbacks. (1) Since the internal solution scatters around, there is a risk of inhaling a large amount of active ingredients floating in the air during processing, which poses a hygiene problem. (2) Splashing of the liquid content may cause stains on furniture and fixtures other than the intended surfaces to be treated, and contamination of the surrounding area cannot be avoided. (3) If the target application surface is not smooth, for example felt-like, the active ingredient cannot reach the roots. It was fraught with such problems. In recent years, as an approach to solving the above problems, furniture polishers and cleaners have been devised that are equipped with donut-shaped brush caps or sponge adapters near the spray nozzle. It is a method that simply sprays the surface and then spreads the content adhering to the surface with a brush or sponge separately installed around the spray nozzle of the aerosol container.
However, the disadvantages of the method still remain unresolved, and there were also problems in that the treatment area was small and the coating could not be applied uniformly. In view of the above-mentioned current situation, the inventor of the present invention has conducted extensive research with the aim of developing a device that can accurately and safely apply active ingredients to clothing, leather, furniture, jackets, etc., and has developed a spray aerosol method. The inventors have discovered that a device that guides the liquid contained in the container from the stem to the application section installed on the side of the aerosol container, causes the content liquid to ooze out from the application surface of the application section, and applies the liquid is suitable for the above purpose and can be safely and effectively processed, and the present invention has been made. completed. That is, the present invention provides an aerosol container 1 having a stem 4 and a nozzle 5, an applicator 8 fixed to the side surface of the aerosol container 1 in the vertical direction of the container, and an applicator extending along the back surface of the applicator 8. The guide part 7 is fixed in communication with the nozzle 5 of the aerosol container 1, and the active ingredient solution in the aerosol container 1 is ejected into the guide part 7 through the stem 4 and the nozzle 5. This is a coating device configured so that the liquid oozes from a portion 7 to a coating portion 8. The coating device of the present invention is a novel device that is completely unexpected from conventional aerosol solution coating devices. An embodiment of the spread aerosol type device of the present invention will be explained with reference to the drawings. 1 and 2 are partial cross-sectional views of an example of the spread aerosol device of the present invention. In the figure, reference numeral 1 denotes an aerosol container, and a mounting cup 3 is fixed to the upper end of its body via a eyelet 2, from which a stem 4 protrudes. This stem 4
A button 6 is connected to the nozzle 5, and when the button 6 is pressed, the content liquid containing the active ingredient can be ejected from the nozzle 5 using the pressure generated by the ejection force of the propellant accumulated inside. has been done. An applicator 9 is fixed to this aerosol container 1 over substantially the entire length in the vertical direction. This applicator 9 has a sheet-like applicator 8 made of a liquid-absorbing material such as felt, open cell material, paper, cloth, non-woven fabric, etc., which may be attached to a support 10 such as a mandrel, or a sheet-like applicator 8 made of a liquid-absorbing material such as felt, which may be attached to a support 10 such as a mandrel, or a sheet-like applicator 8 made of a liquid-absorbing material such as paper, cloth, or non-woven fabric, or a sheet-like applicator 8 that may be attached to a support 10 such as a mandrel, or a sheet-like applicator 8 made of a liquid-absorbing material such as felt, open-cell material, paper, cloth, nonwoven fabric, etc. It has an application part made of a non-liquid-absorbing material designed to be distributed, and a guide part 7 fixedly connected to the nozzle 5 inside the application part 8. In the configuration as described above, when the active ingredient solution in the aerosol container 1 is jetted from the nozzle 5 into the guiding part 7 by pressing the button 6, the solution collides with the baffle plate 11 in the guiding part 7 and , flows down inside the guiding part and moves under the pressure of the liquid continuously ejected from the nozzle 5, and the aerosol container 1
It is possible to uniformly ooze and coat the entire surface from the back side of the coating section 8 installed in the vertical direction. This application method not only allows the active ingredient to be applied effectively, but also eliminates the risk of inhaling the content because the content liquid becomes a mist and does not scatter, but instead oozes into the application area 8 in liquid form and contaminates the surrounding area. No worries, very useful. Also, since the can is used horizontally,
A wide area can be coated efficiently. The coating type aerosol device used in the present invention is of course not limited to this. For example, the shape during application can be arbitrarily selected depending on the purpose of use and the target area to be treated. When applying to large areas such as furniture or clothing, it is extremely efficient as it covers almost the entire length of the aerosol container in the longitudinal direction. It is. On the other hand, when the area to be treated is small, an application section having a partial length in the longitudinal direction is convenient. Furthermore, since the liquid content passes through the guiding part in liquid form, its shape may be arbitrary, as long as the liquid content is guided to the application part. For example, it is also possible to have a structure in which the gas outlet is formed into a pipe and extends to the side of the container, the outlet is provided at an appropriate position on the pipe, and the applicator is attached to the pipe. Furthermore, it is also possible to insert therein, for example a dielectric rod, which regulates the movement of the contents in the structure as illustrated in the figures. Also, the baffle plate is effective for guiding the ejected contents to the inducer, but
For example, this is not always necessary if the applicator is made of a non-liquid-absorbent material or if the upper part of the guide rod is located in a location facing the nozzle outlet. Various solvents can be used for the content liquid filled into the aerosol container in the present invention, including alcohols, ketones, ethers, petroleum, halogenated hydrocarbons, and fluorinated halogenated carbons, depending on the purpose of use. To be determined accordingly. Petroleum-based products generally have good absorption of active ingredients to the coated surface, but the surface is easily wetted. On the other hand, when quick drying and safety are particularly required, it is recommended to use one or two nonflammable mixed solvents such as lower alcohols, ethers, and fluorinated halogenated hydrocarbons with a boiling point of less than 100°C. desirable. As the propellant, any of the conventional spray aerosol propellants can be used, but from the viewpoint of safety against fire, it is desirable to use and mix nonflammable gases. The active ingredients contained in the liquid content in the present invention include:
Carnauba wax, Ceresine wax, furniture cleaners such as Silicone 200, antistatic agents or charge removers containing higher alcohol sulfate ester salts, higher alcohol phosphate ester organic amine salts, stearamide methylpyridinium chloride, octadecyl ethylene Waterproofing agents such as urea and silicone resin, softeners and polishing agents for leather etc. whose main ingredients are Matsukor alcohol, liquid paraffin, glycerin fatty acid ester, etc., mold inhibitors such as sorbic acid and dehydroacetic acid, glycerol and hexachlorophene. glass cleaners containing sodium linear alkylbenzene sulfonate and potassium lorophosphate, stain removers and anti-fogging agents using alcohol, diethylene glycol, etc., metallic soaps containing sorbitan monooleate, naphthenic acid, etc. Rust-preventing moisturizers consisting of etc., sewing moisturizers, sterilizing and deodorizing agents for hospital rooms such as cresol and benzalkonium chloride, hair care agents whose main ingredient is sodium lauryl ethoxylate sulfate ester, etc. , salicylic acid, acrinol, inverse soap, a pet insect repellent insecticide containing pyrethroid compounds, a stuffed parasitic insect insecticide, etc., but the present invention is of course not limited to these. Note that the amount of active ingredient in the content liquid is appropriately determined depending on the application target, application conditions, etc. As described above, the coating device of the present invention is extremely unique in that it is equipped with a special coating device and also employs a spread aerosol method that is designed to be used safely indoors (in terms of toxicity and disasters). The above-mentioned active ingredient can be efficiently and uniformly applied to any surface to be coated. EXAMPLES Hereinafter, the present invention will be explained in more detail with reference to examples, but the present invention is not limited to the following examples unless the gist thereof is exceeded. Test Example 1 Effect Test of Furniture Cleaner Application by the apparatus of the present invention was applied to a 1 m ² furniture surface covered with oily dirt. As a control, the conventional spray method and a device equipped with a doughnut-shaped felt adapter near the spray nozzle were simultaneously used to evaluate the degree of cleanliness after treatment (A), the degree of scattering of the liquid to the surroundings (B), and the treatment performance. The time required (c) was compared. The rankings for each item are as follows: (A) with a high degree of cleaning, (B) with a low amount of liquid content scattering, and (C) with a short processing time. ,,,
