Abstract
Description
Technical Field
[0001] The present invention relates to a liquid evaporation container suitable for in-vehicle use or the like, which can cope with problems such as the ejection of a volatile liquid outside the container even under severe temperature changes, can easily control the evaporation amount of the volatile liquid, and can easily visually confirm the remaining liquid amount.
Background Art
[0002] Conventionally, liquid evaporation containers for accommodating liquid aromatic deodorants or the like that can be attached to a predetermined location inside an automobile or the like are known in various shapes and structures. In a direct liquid type liquid evaporation container that directly accommodates a liquid aromatic deodorant or the like, it is composed of at least a combination of a container that directly accommodates a volatile liquid such as a liquid aromatic deodorant and a porous body or the like that promotes evaporation.
[0003] As a conventional direct liquid type in-vehicle liquid evaporation container, for example, 1) A container body in which an aromatic deodorant is stored from an upper opening, and a manual pump attached to the upper opening of the container body, which is easily and optimally attached to a louver of an air conditioner or the like in an automobile, prevents the aromatic deodorant container from falling off the louver and the evaporation of the aromatic deodorant from ending in a short time due to the wind direction from the louver, and can easily confirm the remaining amount of the aromatic deodorant in the container body. In an aromatic deodorant container in which the aromatic deodorant inside the container body is discharged from the discharge nozzle of the manual pump by the operation of the manual pump, a cap member is attached to the discharge nozzle of the manual pump, a volatilization hole and a cylindrical portion for fitting the discharge nozzle are formed in the cap member, an impregnating body is attached to the outside of the cylindrical portion, and the aromatic deodorant discharged from the discharge nozzle is impregnated into the impregnating body, and the container body is housed in a cover case (see, for example, Patent Document 1).
[0004] 2) To provide a volatilization container that can efficiently volatilize a volatilizing agent, the volatilization container comprises: a container body containing a volatilizing agent; a support member that supports the container body so as to be able to move up and down in an inverted position with its mouth facing downward; a stopper disposed on the support member and fitted liquid-tightly into the mouth of the container body; and an impregnating body disposed on the portion of the support member located below the stopper, into which the volatilizing agent is impregnated, wherein the container body is arranged to be able to move up and down between a forward position in which the stopper opens the mouth and the impregnating body is exposed to the inside of the container body, and a retracted position in which the stopper closes the mouth and the impregnating body is exposed to the outside of the container body. (For example, see Patent Document 2),
[0005] 3) To provide a chemical volatilizer that allows the user to easily control the opening of a vent formed in the housing, the chemical volatilizer is installed near an air outlet and comprises: a container that contains a chemical and has holes through which the chemical seeps out; a first case that holds the container so as to cover it from the outside; and a second case that holds the first case so as to cover it from the outside and is configured to rotate relative to the first case about a rotation axis extending in the front-rear direction, wherein a vent is formed in the first case, and the second case rotates relative to the first case about the rotation axis, thereby having a closed position that closes the vent of the first case and the ventilation of the first case A chemical disperser (see, for example, Patent Document 3) can be switched between an open position and an open position, and one of a first locking element and a plurality of second locking elements arranged around the rotation axis is provided on the first case and the other is provided on the second case, and the first locking element is configured to lock sequentially with the plurality of second locking elements as the second case rotates relative to the first case around the rotation axis, and the first locking element is locked to one of the plurality of second locking elements when the second case is in the closed position, and to another of the plurality of second locking elements when the second case is in the open position, These are some of the known facts.
[0006] However, with the in-car air freshener and deodorizer containers described in Patent Documents 1 to 3, the temperature inside the car fluctuates drastically during sunny days, for example, rising to around 80°C on the dashboard and around 60°C near the air conditioner vents. Furthermore, because the liquid air freshener and deodorizer is composed of volatile liquids, there are issues such as the volatile liquid being sprayed out of the container in response to severe temperature changes, and countermeasures for this have not yet been adequately implemented. In addition, while Patent Document 2 controls the amount of volatile liquid evaporation by allowing the user to control the opening of vents formed in the housing, the structure is complex, and there is a strong desire for a liquid evaporation container that can be controlled more easily.

However, it should be noted that the technical scope of the present invention is not limited to each of the embodiments described in detail below, but extends to the invention described in the claims and its equivalents. Note that the reference numerals common to each drawing represent the same configuration or member, even if not specifically mentioned in the description of each drawing.
[0014] (First Embodiment, Overall Configuration) FIG. 1 shows an example of a liquid evaporation container according to the first embodiment. (a) to (f) are, in sequence, a plan view, a front view, a left side view, a right side view, a longitudinal sectional view, and a bottom view showing the unused state of the liquid evaporation container provided with a clip. FIG. 2 is a perspective view of the liquid evaporation container in the unused state of FIG. 1. FIG. 3 shows an example of an embodiment of the liquid evaporation container of the present invention in a used state. (a) to (f) are, in sequence, a plan view, a front view, a left side view, a right side view, a longitudinal sectional view, and a bottom view showing the used state of the liquid evaporation container provided with a clip. FIG. 4 is a perspective view of the liquid evaporation container in the used state of FIG. 3. As shown in FIGS. 1 to 4, the liquid evaporation container A of the present embodiment includes at least a container body 10 that stores a volatile liquid in a direct liquid state, and a porous evaporation body 40 that has capillary force and evaporates the volatile liquid H stored in the container body 10. The container body 10 is configured to allow visual recognition of the remaining amount of the volatile liquid H, and a liquid storage body 60 is provided between the volatile liquid H in the container body 10 and the porous evaporation body 40.
[0015] As shown in Figures 1 to 5, the container body 10 consists of a front shaft 20 and a rear shaft 30, and in this embodiment, the volatile liquid H is contained within the rear shaft 30. A porous volatile material 40 is attached to the tip side of the front shaft 20, and a liquid reservoir 60 is provided between the volatile liquid H in the rear shaft 30 of the container body 10 and the porous volatile material 40 via a central shaft 50. A cap 70, which serves as a shutter mechanism for opening and closing the volatile liquid H from the container body 10, is rotatably attached to the front shaft 20. A clip is attached to the outer circumference of the front side of the rear shaft 30 of the container body 10 for attachment to louvers of automobile air conditioners, etc.
[0016] (Component composition) The container body 10 is constructed by fitting together and fixing a front shaft 20 and a rear shaft 30, as shown in Figures 6 and 7 (see Figures 2 and 4, etc.). The front shaft 20, as shown in Figures 1 to 5 and 6(a) to (g), has a main body portion 21 which is a cylindrical body that houses the liquid reservoir 60 via a central shaft 50, a tapered end portion 22 which tapers towards the tip of the main body portion 21, and an open portion 24 which is a rectangular frame in plan view with an opening 23 that is open on the upper and lower surfaces and is continuous with the tapered end portion 22. The rear outer circumference of the main body portion 21 has a fitting surface portion 25 for fitting and fixing the rear shaft 30. Furthermore, the inner circumference of the tapered end portion 22 has a convex fitting portion 26 for attaching the porous volatile material 40, and the outer circumference has a rotating surface portion 27 for rotatably attaching a cap 70 which serves as a shutter mechanism.
[0017] As shown in Figures 7(a) to (e), the rear shaft 30 is composed of a bottomed cylindrical body with a sealed rear end. The inner circumferential surface of the front opening 31 has a fitting portion 32 for fitting and fixing with the fitting surface portion 25 of the front shaft 20, and the rear side of this front opening 31 is a press-fit portion 33 into which the central shaft 50 is press-fitted. The outer circumferential surface of the front end of the rear shaft 30 is a clip mounting portion 34 for attaching the clip 80. The volatile liquid H is contained within the rear shaft 30 in a liquid state. If the rear shaft 30 and other components of the container body 10 are made of a material that provides visibility (transparent or translucent material), the remaining amount of volatile liquid H inside the container body 10 can be easily visually inspected.
[0018] The porous volatile body 40 is, for example, bullet-shaped as shown in Figures 8(a) and (b), and has a front portion 41, a central portion 42, and a contact portion 43 that contacts the liquid reservoir 60, extending from the front to the rear. It also has a circumferentially concave fitting groove 44 between the front portion 41 and the central portion 42 for fitting into the convex fitting portion 26 of the front shaft 20. The porous volatile body 40 configured in this way can be any material that possesses capillary action and can cause volatile liquid to volatilize when supplied. Examples include materials formed from porous materials with pores, specifically including sponges, sintered bodies, fiber bundles, foams, sponges, felts, porous bodies, and structures having channels with capillary action inside. Examples of shapes include cylindrical, bullet-shaped, prismatic, pen-nib-shaped, elliptical, and rectangular prismatic shapes. Materials that can be used to form these porous bodies include, for example, natural fibers, animal hair fibers, polyacetal resins, polyethylene resins, acrylic resins, polyester resins, polyamide resins, polyurethane resins, polyolefin resins, polyvinyl resins, polycarbonate resins, polyether resins, and polyphenylene resins. Examples of fiber bundle cores include parallel fiber bundles made of the above-mentioned fiber materials (for example, synthetic fibers of 1 to 20 denier, natural fibers, etc., polyphenylene resins, etc., one or more types of fibers, etc., or combinations of two or more types of fibers) that have been processed, or fiber bundles that have been resin-processed.
[0019] In the case of permeable foams, they can be prepared by known methods, such as pouring molten resin into a mold for molding and foaming. Sintered bodies can be composed of porous bodies (sintered cores) obtained by sintering plastic powders such as polyacetal resins, polyethylene resins, acrylic resins, polyester resins, polyamide resins, polyurethane resins, polyolefin resins, polyvinyl resins, polycarbonate resins, polyether resins, and polyphenylene resins. The porous volatile material 40, including cases where it is composed of these sintered cores, preferably has a pore diameter of 10 μm to 1,000 μm, more preferably 20 μm to 300 μm, and particularly 20 μm to 100 μm, as measured by SEM image analysis, and the porosity is preferably 20 to 90%, and more preferably 30 to 80%. In this disclosure, "porosity" is calculated as follows. First, an aromatic volatile material having a known mass and apparent volume is immersed in water, and after being thoroughly soaked in water, the mass is measured after being removed from the water. From the measured mass, the volume of water soaked into the aromatic volatile material is derived. Assuming that this volume of water is the same as the pore volume of the aromatic volatile material, the porosity is calculated from the following formula. Porosity (unit: %) = (volume of water) / (apparent volume of aromatic volatile material 30) × 100
[0020] Furthermore, the porous volatile material 40 can be composed of a carbon porous body. The pore size of the carbon porous body is preferably 10 μm to 1,000 μm, more preferably 20 μm to 100 μm, as measured by SEM image analysis, and the porosity is preferably 20 to 90% as measured by the same method. As for the shape, examples include cylindrical, bullet-shaped, prismatic, pen-tip-shaped, elliptical, and rectangular prismatic shapes, as described above. This carbon porous body can be any porous structure having fine interconnected pores. Examples include carbon composite molded bodies composed of amorphous carbon and carbon powder, consisting of a three-dimensional network structure or a point-sintered structure, isotropic high-density carbon molded bodies, carbon fiber papermaking molded bodies, activated carbon molded bodies, etc. Preferably, a carbon composite molded body having the above-mentioned pore size and porosity and having fine interconnected pores made of amorphous carbon and carbon powder is desirable. For the carbon powder used to produce this porous carbon composite, it is preferable to use at least one (either alone or in combination of two or more) selected from highly oriented pyrolysis graphite (HOPG), quiche graphite, natural graphite, artificial graphite, carbon nanotubes, and fullerenes, in order to further improve reaction efficiency. Furthermore, when the porous volatilizer 40 is made of a carbon porous body, the volatilization of the porous volatilizer 40 may be further enhanced by making it consist of a liquid-permeable portion that is impregnated with a volatile liquid and a heat-absorbing portion that is not impregnated, and / or by forming slits in the carbon porous body. The porous volatile material 40 of this embodiment is configured in a cylindrical shape, but in order to further improve aroma volatilization, the cross-section may be formed in a rectangular shape. A rectangular shape is a polygonal shape including a square, and a rectangle with a different aspect ratio on one side is particularly preferred. By using a rectangular shape, the surface area can be increased compared to a circular cross-section of the same volume, and the aroma performance can be improved. The aspect ratio of the rectangular cross-section is preferably 1:1 to 1:13, and more preferably 1:1.1 to 1:1.4, which ensures the rigidity of the porous volatile material 40.
[0021] The central shaft 50 is a cylindrical member for attaching a liquid reservoir 60, which is provided between the volatile liquid H contained in the rear shaft 30 of the container body 10 and the porous volatile material 40 attached to the front shaft 20, as shown in Figures 9(a) to (g). Its outer surface is an inlet surface portion 51 that is pressed into the rear shaft 30, and the rear interior 55 is configured to receive the volatile liquid by press-fitting. Inside the central shaft 50 is a volatile liquid guide tube 52 through which the volatile liquid H in the rear shaft 30 passes by capillary action, and an air exchange tube 53 through which replacement air passes to the rear shaft 30 side. The rear rod-shaped portions 61, 61, ... of the liquid reservoir 60 are attached to the insertion spaces 54, 54... which are spaces formed between the volatile liquid guide tube 52 and the air exchange tube 53 through which the replacement air passes. The diameter and length of the volatile liquid guide tube 52 and air exchange tube 53 described above are determined based on the type of volatile liquid, capillary force, and other factors to determine the most suitable diameter and length.
[0022] The liquid reservoir 60 can be any structure that can serve as a temporary reservoir for volatile liquid H. Examples include a porous material with pores, specifically a sponge, sintered body, fiber bundle, foam, sponge, felt, porous body, or a structure having a channel with capillary action inside. In terms of shape, examples include a cylindrical body with multiple rod-shaped parts on the rear side of the above embodiment, as well as a bullet-shaped body, a rectangular prismatic body, an elliptical prismatic body, a rectangular prismatic body, and so on. By providing a cylindrical or similar liquid reservoir 60 within the rear shaft 30, which forms the container body 10, via the central shaft 50, it can serve as a temporary reservoir for the volatile liquid H. This configuration eliminates problems such as the volatile liquid, which is contained in a direct liquid state within the rear shaft 30, being ejected outside the container body 10, even under severe temperature changes. Furthermore, since the front side of the liquid reservoir 60 is in contact (including joining) with the contact portion 43 of the porous volatile material 40, the volatile liquid H can be efficiently supplied to the porous volatile material 40.
[0023] The cap 70 is a shutter mechanism that allows the volatile liquid from the container to evaporate freely. As shown in Figures 10(a) to (g), for example, the cap 70 is made up of a cylindrical body with a sealed front end, and slit-shaped ventilation grooves 71, 71… for the volatile liquid to evaporate are formed on the upper and lower surfaces (at 180° intervals) of the outer circumference, and the rear opening 72 is attached to the rotating surface portion 27 of the front shaft 20, so that the cap 70 fits onto the front end of the front shaft 22 and can slide in the rotational direction. By adjusting the rotation of the cap 70 (for example, every 90°), the amount of volatile liquid evaporating from the porous volatile material 40 can be arbitrarily controlled. Since the openings 23 of the front shaft 20 are provided on the upper and lower surfaces (every 180°), if the slit-shaped ventilation grooves 71, 71... of the cap 70 for the volatile liquid to evaporate are aligned with these openings, the volatile liquid from the porous volatile material 40 will evaporate out of the container through the slit-shaped ventilation grooves 71, 71... (see Figure 4). By shifting the rotation of the cap 70, the slit-shaped ventilation grooves 71,... will be gradually blocked, so the amount of volatile liquid evaporating will gradually decrease. If the upper and lower openings 23 of the front shaft 20 are blocked by the sealing surface portion 73 of the cap 70 other than the slit-shaped ventilation grooves 71, 71..., the amount of volatile liquid evaporating can be adjusted to a state close to zero. Furthermore, by increasing or decreasing the size and shape of the slit-shaped ventilation grooves 71, 71..., the amount of volatile liquid volatilized can be controlled.
[0024] As shown in Figures 1 to 4 and Figures 11(a) to (c), the clip 80 has curved retaining bodies 82, 82 on both ends of the clip body 81 for holding the clip mounting portion 34 of the rear shaft 30 of the container body 10, and a pair of clamping bodies 83, 83 on the upper central side of the clip body 82 for attaching it by clamping to the louvers of an automobile air conditioner or the like.
[0025] The materials used for the front shaft 20, rear shaft 30, middle shaft 50, cap 70, etc., that constitute the container body 10 are not particularly limited as long as they do not affect the physical properties of the stored volatile liquid. For example, they can be made of metal, or at least one of thermoplastic resins such as polyacetal resin, polyethylene resin, acrylic resin, polyester resin, ethylene-vinyl alcohol copolymer resin (EVOH), polyamide resin, polyurethane resin, polyolefin resin, polyvinyl resin, polycarbonate resin, polyether resin, or polyphenylene resin, or thermosetting resin. Preferably, they are made of materials that have high air barrier properties. Examples of materials with high air barrier properties include the above-mentioned EVOH, metal foil, metal vapor deposition tanks, and carbon materials. Examples of materials with high air barrier properties include the above-mentioned EVOH alone, or a container body made of EVOH, the above-mentioned thermoplastic resin, or thermosetting resin, to which at least two layers of metal foil, metal vapor deposition, or carbon material (including diamond-like carbon material) that also possess air barrier and humidity barrier properties are bonded or vapor-deposited on the inner and / or outer surfaces. These composite materials are then molded into various parts of the target container body 10, for example, by molding methods such as co-extrusion, multilayer injection molding, and multilayer blow molding. Furthermore, it is formed from materials that have high solvent resistance. Examples of materials with high solvent resistance include PEN (polyethylene naphthalate) or composite materials of PP and PEN. Each component of this embodiment, including the container body 10, is composed of a multilayer structure in which the outer layer and inner layer are made of polypropylene (PP) resin, and the intermediate layer sandwiched between the outer and inner layers is made of nylon or ethyl vinyl alcohol (EVOH) resin and formed by blow molding.
[0026] The volatile liquid to be filled (contained) in the container body 10 is not particularly limited, but various synthetic fragrances, natural fragrances, and their constituent components, as well as volatile aromatic and deodorizing liquid components that have deodorizing properties, effective effects such as forest bathing effects, calming effects, or stimulating effects that wake people up, can be used individually or in mixtures of two or more of these. Examples of fragrance and deodorizing components include hydrocarbons such as aliphatic hydrocarbons, terpene hydrocarbons, and aromatic hydrocarbons; alcohols such as aliphatic alcohols, terpene alcohols, and aromatic alcohols; ethers such as aliphatic ethers and aromatic ethers; oxides such as aliphatic oxides and terpene oxides; aldehydes such as aliphatic aldehydes, terpene aldehydes, aliphatic cyclic aldehydes, thioaldehydes, and aromatic aldehydes; ketones such as aliphatic ketones, terpene ketones, aliphatic cyclic ketones, non-benzene aromatic ketones, and aromatic ketones; acetals; ketals; phenols; phenol ethers; fatty acids; and terpene carboxylic acids. One or more synthetic fragrances such as aliphatic cyclic carboxylic acids, aromatic carboxylic acids, acid amides, aliphatic lactones, macrocyclic lactones, terpene lactones, aliphatic cyclic lactones, aromatic lactones, etc., esters such as aliphatic esters, furan carboxylic acid esters, aliphatic cyclic carboxylic acid esters, cyclohexyl carboxylic acid esters, terpene carboxylic acid esters, aromatic carboxylic acid esters, nitrogen-containing compounds such as nitromusks, nitriles, amines, pyridines, quinolines, pyrrole, indole, etc., and natural fragrances from animals and plants, and blended fragrances containing natural and / or synthetic fragrances may be used in combination. For example, synthetic fragrances that can be used include those listed in "Synthetic Fragrances: Chemistry and Product Knowledge" by Motoichi Indo, published by Kagaku Kogyo Nippo Co., Ltd. in 1996, and "Perfume and Flavor Chemicals" by Stephen Arctander, published by Montclair, NJ in 1969.

[0028] Furthermore, diethyl phthalate, dipropylene glycol, benzyl benzoate, isopropyl myristate, Harcoline, isopentane, orange terpenes, etc., can be used as solvents or fixatives for the fragrance. The amount of these liquid fragrance and deodorizing components is usually appropriately selected from a range of 0.1 to 10% by mass, preferably 1 to 8% by mass, in the total amount of volatile liquid (composition). If the amount of these liquid fragrance and deodorizing components is less than 0.1% by mass, a sufficient effect cannot be obtained, and if it exceeds 10% by mass, the amount of surfactant etc. required becomes too large, making it difficult to maintain the persistence of the fragrance and deodorization. Furthermore, it is uneconomical in terms of cost.
[0029] The volatile liquid used in the present invention uses water (purified water, distilled water, ion-exchanged water, pure water, ultrapure water, etc.) as a solvent, and other surfactants or other conventionally used components may be added as needed, to the extent that they do not impair the effects of the present disclosure. Other preferred anionic surfactants include alkyl sulfates, polyoxyethylene alkyl ether sulfates, alkylallyl ether sulfates, alkylbenzene sulfonates, alkylnaphthalene sulfonates, α-sulfo fatty acid salts, alkyl sulfonates, alkyl sulfosuccinates, α-olefin sulfonates, fatty acid soaps, alkyl ether carboxylates, acylalaninates and acyltaurates, amino acid-based anionic surfactants or their salts, such as N-alkyliminodicarboxylic acids, alkyl phosphates, alkyl ether phosphates, alkylphenyl ether phosphates, and alkyl phosphate ester salts. Other preferred amphoteric or semipolar surfactants include amine oxides, alkyl betaines, fatty acid amide alkyl betaines, hydroxysulfobetaines, imidazolines, alkylglycines, and alkylalanines. Preferred nonionic surfactants include polyoxyethylene alkyl ethers, sorbitan fatty acid esters, polyoxyethylene acyl esters, alkyl polyglycosides, fatty acid glycoside esters, fatty acid methyl glycoside esters, alkyl methyl glucamides, and fatty acid alkanolamides. Other possible additives include components that maintain stable volatilization (propylene carbonate), preservatives, antioxidants, UV absorbers, pH adjusters, hydrotropes, inorganic salts, and dyes.
[0030] The volatile liquid used may be given pseudoplastic properties for ease of use and leakage resistance. Pseudoplastic properties can generally be imparted using thickeners (gelling agents), etc. Pseudoplastic properties refer to the property of exhibiting non-flowability in a static state but becoming flowable when a shear force is applied. Examples of thickening agents that can be used include at least one selected from alkali-swelling-association emulsions, alkali-swelling emulsions, polyvinylpyrrolidone, cellulose derivatives, xanthan gum, succinoglycans, dieutan gum, guar gum, carrageenan, pectin, or cellulose derivative cross-linked acrylic acid polymers, oxidized cellulose, crystalline cellulose, rheozan gum, gellan gum, montmorillonite clay minerals, and other inorganic thickening agents.
[0031] The liquid vaporization container A of this embodiment, configured in this way, is used perpendicular to the vertical direction, and this liquid vaporization container A is configured to allow an inclination of ±45 degrees. In the liquid volatilization container A of this embodiment, by rotating the cap 70, which serves as a shutter mechanism, and adjusting the rotation of the cap 70 (for example, every 90°), the volatile liquid contained in a direct liquid state on the rear shaft 30 of the container body 10 is supplied to the volatile liquid guide tube 52 on the central shaft 50, the liquid reservoir 60 which serves as a temporary storage body, and the porous volatilizer 40, and the amount of volatile liquid volatilized from the porous volatilizer 40 can be arbitrarily controlled. Since the opening 23 of the front shaft 20 is provided on the upper and lower surfaces, if the slit-shaped ventilation grooves 71, 71... of the cap 70 are aligned with this, the volatile liquid from the porous volatile body 40 will evaporate out of the container through the slit-shaped ventilation grooves 71, 71..., and at least one type of fragrance / deodorizing component contained in the volatile liquid H, such as a fragrance-emitting component, a deodorizing component, a component that emits effective effects such as a forest bathing effect, a component that has a calming effect on people, or a component that has an awakening effect that wakes people up, will evaporate from the ventilation grooves 71, 71..., and by selecting the type of volatile liquid to use, it is possible to provide fragrance or deodorization according to the purpose in the car interior, etc., and the cap When the cap 70 is closed, that is, when the cap 70 is rotated 90° to seal the opening 24 with the sealing surface 73, the evaporation of volatile liquids such as liquid fragrance deodorizers from the ventilation grooves 71, 71... is restricted, so evaporation from the porous volatile material 40 gradually stops. The shutter mechanism (cap) 70, which is fitted and rotatable by sliding the cap 70, can be reliably made to a near-sealed state, and the liquid reservoir 60 can be used as a temporary reservoir for volatile liquids even in the face of severe temperature changes, so problems such as volatile liquids spraying out of the container can be dealt with without issue. Furthermore, if the rear shaft 30 is made of a visible material, the remaining liquid amount can be easily seen, providing a liquid volatile container suitable for use in vehicles and the like. In the above embodiment, the opening 24 is opened and closed by a 90° rotation, which acts as a shutter mechanism, thereby opening and closing the volatilization of the porous volatile material 40. However, since the cap 70 is fitted and slidable at the tip of the front shaft 20, the amount of volatilization (amount of air passing through the slit groove 71) can be adjusted by the rotation angle. [Examples]
[0032] Next, the present invention will be described in more detail with reference to examples, but the present invention is not limited to the following examples.
[0033] (Example 1: Liquid volatilization container A conforming to Figures 1 to 11) A direct-liquid type liquid volatilization container conforming to Figures 1 to 11 was fabricated using the following components: a front shaft 20, a rear shaft 30, a porous volatile material 40, a middle shaft 50, a liquid reservoir 60, a cap 70, a clip 80, etc., which constitute the container body 10. A volatile liquid with the following composition was used.
[0034] (Main components of direct-liquid type air freshener / deodorizer container A) The container body 10 consists of a front shaft 20, a rear shaft 30, a middle shaft 50, a cap 70, and a clip 80. Both are made of polyethylene naphthalate, with a planar viewing area of 24 openings: approximately 0.8 cm². 2 Porous volatile material 40: A porous carbon material produced by calcining amorphous carbon and carbon powder; size: φ8 × 25 mm; porosity 60% Center shaft: Volatile liquid guide tube 52 size: Hole diameter φ1.5mm × length 20mm Air exchange pipe 53 dimensions: Hole diameter φ1.5mm x length 20mm Liquid reservoir 60: A porous carbon body made by calcining amorphous carbon and carbon powder; size: φ15 × 50 mm (size excluding the rear rod-shaped part); porosity 80% Cap (shutter mechanism) 70: Slit groove size 71, 71...: Width 1mm x Length 10mm
[0035] (Composition of volatile liquids) A volatile liquid with the following composition (total 100% by mass) was used. Fragrance: 1.5% by weight Surfactant (polyoxyethylene styrylphenyl ether): 3% by mass Deodorizer (mixture of betaine compound, amine compound, and organic acid compound): 0.2% by mass Preservative (2-n-octyl-4-isothiazolin-3-one): 0.03% by mass Ion-exchanged water: 95.27% by mass Viscosity (25°C): 3 mPa·s (E-type viscometer, TV-25, manufactured by Toki Sangyo Co., Ltd.)
[0036] When the liquid evaporation container A obtained in Example 1, conforming to Figures 1 to 11, was used, it was confirmed that by rotating the cap 70, which acts as a shutter mechanism, the fragrance and deodorizing components contained in the volatile liquid evaporate, creating a pleasant atmosphere. It was also confirmed that by rotating the cap 70 90° to close the slit groove 71, the evaporation of the volatile liquid gradually ceases. Furthermore, problems such as the volatile liquid spraying out of the container even under severe temperature changes can be easily handled by the liquid storage section 60, which acts as a temporary storage body, provided in the liquid evaporation container A. In addition, since the container body is made of a material that allows for easy visual confirmation of the remaining liquid amount, it was confirmed that a liquid evaporation container suitable for use in vehicles and other applications can be obtained. [Industrial applicability]
[0037] This liquid volatilization container is suitable for automotive applications and other uses, as it can withstand extreme temperature changes without problems such as volatile liquids spraying out of the container, allows for easy control of the amount of volatile liquid evaporated, and makes it easy to visually check the remaining liquid level.
