Description

This invention relates to a liquid volatilization container suitable for automotive applications and other uses, which can withstand extreme temperature changes without problems such as the volatile liquid spraying out of the container, allows for easy control of the amount of volatile liquid evaporated, and also allows for easy visual confirmation of the remaining liquid level.

Conventionally, liquid volatile containers for liquid air fresheners and deodorizers that can be easily attached to designated locations inside automobiles are known to come in a wide variety of shapes and structures.
A direct-liquid type liquid volatilization container that directly contains liquid fragrances and deodorizers consists of at least a container that directly contains a volatile liquid such as a liquid fragrance and deodorizer, and a porous material or the like that promotes volatilization.

Conventional direct-liquid type liquid volatile containers for automotive use, for example,
1) A fragrance deodorizer container that can be easily and optimally attached to the louvers of an automobile air conditioner, etc., preventing the fragrance deodorizer container from falling off the louvers or the fragrance deodorizer from being quickly dispersed due to the direction of the airflow from the louvers, and allowing easy confirmation of the remaining amount of fragrance deodorizer in the container body, comprising a container body in which a fragrance deodorizer is stored through an opening at the top, and a manual pump attached to the opening at the top of the container body, wherein the fragrance deodorizer inside the container body is discharged from the discharge nozzle of the manual pump when the manual pump is operated, wherein a cap member is attached to the discharge nozzle of the manual pump, the cap member has a cylindrical portion formed to fit the dispersion hole and the discharge nozzle, an impregnating body is attached to the outside of the cylindrical portion, the fragrance deodorizer discharged from the discharge nozzle is impregnated with the impregnating body, and the container body is housed in a cover case (see, for example, Patent Document 1).

2) To provide a volatilization container that can efficiently volatilize a volatilizing agent, a volatilization container is provided comprising: 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, in which the volatilizing agent is impregnated, wherein the container body is arranged to be able to move up and down between an advanced 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 (see, for example, Patent Document 2).

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 the first case has a vent formed therein, and the second case rotates relative to the first case about the rotation axis to have a closed position that closes the vent of the first case and an open position that opens the vent of the first case. A known example of a chemical disperser (see, for example, Patent Document 3) is known in which the open and closed positions can be switched, 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 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.

However, with the in-car air freshener and deodorizer containers described in Patent Documents 1 to 3, the temperature inside the car fluctuates drastically under sunny conditions, for example, rising to around 80°C on the dashboard and around 60°C near the air conditioning vents. Furthermore, because the liquid air freshener and deodorizer is a volatile liquid, there are issues such as the volatile liquid being released outside the container in response to extreme temperature changes, and countermeasures for this remain insufficient. Additionally, while Patent Document 2 allows the user to control the opening of vents formed in the housing to control the amount of volatile liquid released, its structure is complex, and there is a strong need for a liquid volatilization container that can be controlled more easily.

Japanese Patent Publication No. 2000-202014 (Claims, Figures 1-4) Japanese Patent Publication No. 2016-190670 (Claims, Figure 1) Japanese Patent Publication No. 2020-104920 (Claims, Figure 1, etc.)

Embodiments of this disclosure will be described in detail below with reference to the drawings. However, it should be noted that the technical scope of the present invention is not limited to each of the embodiments described below, but extends to the invention described in the claims and its equivalents.
Furthermore, symbols commonly used across all drawings represent the same configuration or component, even if not specifically mentioned in the descriptions of each drawing.

(First embodiment, overall configuration)
Figure 1 shows an example of an unused liquid volatilization container according to the first embodiment, and Figure 2 shows another example of an unused container. Figures 1 and 2(a) to (d) are, in order, a front view, a top view, a left side view, and a longitudinal cross-sectional view.
As shown in Figures 1 and 2, the liquid volatilization container A of this embodiment comprises at least a container body 10 for containing a volatile liquid in a liquid state, and a porous volatilizer 40 that has capillary force and volatilizes the volatile liquid H contained in the container body 10, wherein the container body 10 allows for visual confirmation of the remaining amount of volatile liquid H, and the container body 10 has a gas-liquid separation member 50 at its opening.

As shown in Figures 1 to 4, the container body 10 consists of a liquid cartridge 20 and an outer shaft 30. In this embodiment, the liquid cartridge 20 is detachably mounted inside the outer shaft 30, and the volatile liquid H is contained within the liquid cartridge 20. A porous volatile body 40 is attached to the tip of the outer shaft 30 via a holding member 45, and the rear end of the porous volatile body 40 is inserted into the volatile liquid inside the liquid cartridge 20 via a gas-liquid separation member 50, which also serves as an inner stopper installed inside the liquid cartridge 20.
The outer circumference of the tip side of the outer shaft 30 is configured to have a shutter member 60 and a clip-equipped cap 70 attached to it.
Furthermore, a tail plug 80 is detachably attached to the rear opening 32 of the outer shaft 30, and by removing this tail plug 80, the liquid cartridge 20 can be easily replaced when the volatile liquid inside the liquid cartridge 20 is consumed.

(Component composition)
As shown in Figures 1 to 4, the container body 10 of this embodiment consists of a liquid cartridge 20 and an outer shaft 30, and in this embodiment, the liquid cartridge 20 is detachably mounted inside the outer shaft 30.
As shown in Figures 3(a) to (g), the liquid cartridge 20 is composed of a cylindrical body 21, and a gas-liquid separation member 50 is installed inside the front opening 22.
This liquid cartridge 20 contains a volatile liquid H, and an elastomer or rubber sealing member 24 is fixed to the rear opening 23 to seal the opening 23. The liquid cartridge 20 containing the volatile liquid H is replaceable, and although not shown in the figure, a lid member or the like is attached to the front opening 21 of the replacement liquid cartridge before use.

As shown in Figures 1 to 2 and 4(a) to (g), the outer shaft 30 is composed of a cylindrical body 31, and the liquid cartridge 20 with the above configuration is inserted into the opening 32 at the rear end, and the tail plug 80 is attached to the opening 32 by fitting such as light press-fitting.
Furthermore, the outer circumferential surface on the front side of the outer shaft 30 has a mounting surface portion 34 with a concave fitting surface portion 33 for allowing the clip-attached cap 70 to rotate and slide, and further forward of this mounting surface portion 34, there is an integrally formed small-diameter portion 35 that reduces the diameter.
Inside the mounting surface 34 of the outer shaft 30, a radial contact body 35 is formed, consisting of six contact portions 35a, 35a... that contact the front end surface of the liquid cartridge 20 to which the gas-liquid separation membrane member (internal stopper) 50 is attached. The central part of the radial contact body 35 has an insertion hole 36 into which the porous volatile material 40 is inserted. Support protrusions 36a, 36a... are provided on the inner circumferential surface on the front side of the insertion hole 36. Furthermore, a shutter member 60 is fixed to the outer circumferential surface of the small diameter portion 34 of the outer shaft 30, and the porous volatile material 40 is fixed inside the small diameter portion 34 via a holding member 45 as shown in Figures 5(a) to (f).
If the liquid cartridge 20, 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 in the liquid cartridge 20 can be easily visually inspected.

The porous volatile material 40 is, for example, rod-shaped as shown in Figures 5(a) to (f), and is slightly tapered from the front to the rear, and is fixed to the mounting hole 46 of the holding member 45.
The retaining member 45 has a mounting hole 46 formed in its longitudinal direction, and the front side has a tapered portion 47 that narrows towards the front, and the rear side of the tapered portion 47 has a reduced diameter portion 48 which is reduced in diameter, and the upper and lower surfaces of the reduced diameter portion 48 have concave air exchange grooves 49, 49.
As shown in Figures 5(a) to (f), the rod-shaped porous volatilizer 40 is attached to the holding member 45, with the tip of the porous volatilizer 40 becoming the volatile portion 41 of the volatile liquid. The holding member 45 with the porous volatilizer 40 attached is then fitted into the small diameter portion 34 of the outer shaft 30, to which the liquid cartridge 20 is mounted, by press-fitting or the like, so that the rear side of the porous volatilizer 40 is inserted into the volatile liquid contained in the liquid cartridge 20.

The porous volatile body 40, configured in this way and attached to the holding member 45 of the above configuration, can be any material that possesses capillary action and can cause volatile liquid to volatilize when supplied. Examples include porous materials with pores, specifically sponges, sintered bodies, fiber bundles, foams, sponges, felts, porous bodies, and structures having internal channels with capillary action. 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, ..., a combination of one or more types of polyphenylene resins, etc.) that have been processed, or fiber bundles that have been resin-processed.

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) made 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 as measured by SEM image analysis, more preferably 20 μm to 300 μm, and particularly 20 μm to 100 μm, 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 the water has sufficiently permeated it, the mass is measured after it is removed from the water. From the measured mass, the volume of water that has permeated 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

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 prism, and rectangular prism.
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 in this embodiment is configured in a cylindrical shape, but in order to further improve the volatile properties, 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 each 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 volatile properties 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.

As shown in Figures 6(a) to (f), the gas-liquid separation member 50 has an insertion hole 52 with a fitting and holding portion 51 for inserting and holding a rod-shaped porous volatile body 40 into its central interior. The rear interior side of the gas-liquid separation member 50 has six radial partition portions 53, 53..., with spaces between each partition portion 53. In addition, a concave air exchange portion 54 for air exchange is formed on the bottom side of the gas-liquid separation membrane member (internal plug) 50. As described above, the gas-liquid separation member 50 is configured to be fixed inside the opening 22 of the liquid cartridge 20 by fitting or the like. The gas-liquid separation member 50 can be removed after use.
The gas-liquid separation member 50 used in the present invention is preferably a porous material that has solvent resistance, water-repellent and oil-repellent properties to volatile liquids, is a microporous membrane that allows gas to permeate but does not allow volatile liquids (including solvents) to permeate, and has electrical insulating properties.
Such a gas-liquid separation member 50 can be, for example, a membrane made of a fluororesin such as polyvinylidene fluoride or polytetrafluoroethylene. Specifically, examples include polyvinylidene fluoride (trade name Eslon PVDF, manufactured by Sekisui Chemical Co., Ltd.) and polytetrafluoroethylene (trade name: Gore-Tex®, manufactured by W.L. Gore & Associates, USA). The thickness of this gas-liquid separation member only needs to be such that it can maintain sufficient strength to function as a base material, and can be, for example, 0.5 to 20 mm. In this embodiment, it is made of polyvinylidene fluoride and molded. By using this gas-liquid separation member 50, even in a liquid volatilization container having a liquid cartridge 20 containing a volatile liquid that forms a direct liquid storage mechanism, a closed space is not formed, and as a result, the gas-liquid separation member 50 can prevent the volatile liquid from spraying out from the porous volatilizer due to temperature changes, etc.

As shown in Figures 7(a) to (g), the shutter member 60 is composed of a cylindrical body 61 with a sealed front end. Slit-shaped ventilation grooves 62, 62… are formed on the upper and lower surfaces (at 180° intervals) of the outer circumferential surface on the front side, allowing the volatile liquid to evaporate. The rear opening 63 is attached to the outer circumferential surface of the small-diameter portion 34 of the outer shaft 30 by press-fitting or the like (see Figures 1 and 2). In this embodiment, the shutter member 60 and the clip-attached cap 70 (described later) constitute a shutter mechanism that allows for the opening and closing of the volatile liquid evaporation from the liquid evaporation container.

As shown in Figures 8(a) to (g), the clip-on cap 70 has a cylindrical fitting cylinder portion 71 that fits onto the mounting surface 34 on the outer circumference of the outer shaft 30, a convex fitting portion 72 on the inner circumference of the rear side of the fitting cylinder portion 71 that allows the clip-on cap 70 to rotate and slide on the concave fitting surface portion 33 of the outer shaft 30, a clip portion 73 having clip balls 73a, 73a integrally attached to the outer circumference of the fitting portion 71, and a cylindrical portion 74 integrally located on the front side of the fitting cylinder portion 71 and having openings 74a, 74a on its upper and lower surfaces.
By attaching this clip-equipped cap 70 to the concave fitting surface portion 33 and the small diameter portion 35 on the front side of the outer shaft 30, it becomes rotatable and slidable with respect to the outer peripheral surfaces of the shutter member 60 and the mounting surface 34 of the outer shaft 30.

The tail plug 80 closes the rear end opening 32 of the outer shaft 30 and is a member that fits and holds the rear end of the liquid cartridge 20 housed in the outer shaft 30. As shown in Figures 9(a) to (g), it consists of a cylindrical body 81 with the rear end sealed, a flange portion 82 that contacts the opening 32 is formed on the outer circumferential surface slightly rear of the center, and the front cylindrical portion 83 contacts and holds the rear end of the liquid cartridge 20. The cylindrical portion 83 has contact ribs 84, 84... at 90° intervals on the inner circumference on the rear side for contacting and holding the rear end of the liquid cartridge 20, and a fitting step portion 85 is formed thereon.
As shown in Figures 1 and 2, the tail plug 80 configured in this way will abut and hold the rear end of the liquid cartridge 20 housed in the outer shaft 30 by fitting, and will also close the rear end opening 32 of the outer shaft 30.
Furthermore, when the volatile liquid in the liquid cartridge 20 is used up, that is, the remaining amount of volatile liquid in the liquid cartridge 20 can be easily seen inside the liquid cartridge 20 through the outer shaft 30. Therefore, when replacing the liquid cartridge 20, it can be easily replaced by removing the tail plug 80 from the opening 83 of the outer shaft 30, taking out the consumed liquid cartridge 20 from the outer shaft 30, and installing a new liquid cartridge 20.

The materials used for the liquid cartridge 20, outer shaft 30, holding member 35, shutter member 60, clip-on 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 the above-mentioned EVOH, 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 components of the target container body 10, such as the liquid cartridge 20 and outer shaft 30, using various 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.

The volatile liquid to be filled (contained) in the liquid cartridge 20 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.

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 suitable 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.

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, alkyl allyl ether sulfates, alkylbenzene sulfonates, alkyl naphthalene sulfonates, α-sulfo fatty acid salts, alkyl sulfonates, alkyl sulfosuccinates, α-olefin sulfonates, fatty acid soaps, alkyl ether carboxylates, acyl alaninates and acyl taurates, 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.

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.

In the liquid volatilization container A of this embodiment, the shutter mechanism, which consists of a shutter member 60 and a clip-on cap 70, allows for arbitrary control of the amount of volatile liquid volatilized from, for example, the volatilization portion 41 of the porous volatilizer 40. Specifically, the shutter member 60 is attached to the upper and lower surfaces of the volatilization portion 41 so as to meet the slit-shaped ventilation grooves 61, 61... of the shutter member 60 for the volatile liquid to volatilize. By adjusting the rotation of the clip-on cap 70 as shown in Figures 1 and 2 (for example, by rotating it 90°), the volatile portion 41, the slit-shaped ventilation grooves 61, 61..., and the openings 75, 75 of the porous volatile body 40 become aligned vertically. As a result, the volatile liquid contained in the liquid cartridge 20 is supplied to the porous volatile body 40 by capillary force, etc., and volatilizes (disperses) out of the container through the volatile portion 41, the slit-shaped ventilation grooves 61, 61..., and the openings 75, 75 on its upper and lower surfaces. This allows the aromatic components, deodorizing components, and forest bathing effects contained in the volatile liquid H to be released. At least one fragrance or deodorizing component, such as an effective component, a component that has a calming effect on people, or a component that has an awakening effect to wake people up, will volatilize. By selecting the type of volatile liquid to use, it is possible to provide fragrance or deodorization in the car or other places according to the purpose. By returning the clip-on cap 70 to its original position, the volatilization of the openings 75, 75 is closed, that is, by rotating the cap 70 by 90°, the volatilization of volatile liquids such as liquid fragrance deodorizers from the ventilation grooves 61, 61... is restricted, and the volatilization from the volatile part 41 of the porous volatile body 40 gradually disappears.
The clip-on cap 70 has a fitting and sliding rotation mechanism that allows for easy control of the amount of vaporization, and it is portable. Even in the case of severe temperature changes, by using a gas-liquid separation member 50 inside the liquid cartridge 20, a closed space is not formed in the liquid vaporization container A which has a liquid cartridge 20 containing a volatile liquid that forms a direct liquid storage mechanism. As a result, the gas-liquid separation member 50 also prevents the volatile liquid from spraying out from porous volatile materials due to temperature changes and the like.

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.

(Example 1: Liquid evaporation container A according to Figures 1 to 9)
A direct-liquid type liquid volatilization container conforming to Figures 1 to 9 was fabricated using a liquid cartridge 20, outer shaft 30, porous volatile material 40, gas-liquid separation member 50, shutter member 60, clip-attached cap 70, tail plug 80, etc., which constitute the container body 10 as described below. A volatile liquid with the following composition was used.

(Main components of direct-liquid type air freshener/deodorizer container A)
The liquid cartridge 20, outer shaft 30, holding member 45, shutter member 60, clip-on cap 70, and tail plug 80, which form the container body 10, are all made of polyethylene naphthalate. The planar area of the opening 75 is approximately 0.03 ^cm².
Porous volatile material 40: A porous carbon material produced by calcining amorphous carbon and carbon powder; size: φ2 × 40 mm; porosity 60%
Gas-liquid separation member 50: Made of polyvinylidene fluoride; physical properties: porosity 50%, size: φ15 × 25 mm, maximum thickness in the width direction: 2 mm
Shutter member 60: Size of slit grooves 61, 61...: Width 1 mm x Length 5 mm

(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.)

When the liquid vaporization container A, obtained in Example 1 and conforming to Figures 1 to 9, was used, it was confirmed that by rotating the clip-on cap 70 of the liquid vaporization container A of Example 1, the fragrance and deodorizing components contained in the volatile liquid vaporized through the vaporization section 41, slit grooves 61, 61, and openings 75, 75, creating a pleasant atmosphere. Furthermore, it was confirmed that by rotating the clip-on cap 70 90° to close the slit grooves 71, the vaporization of the volatile liquid gradually ceased. In addition, problems such as the volatile liquid spraying out of the container due to severe temperature changes could be handled without issue by the gas-liquid separation member 50 provided in the liquid vaporization container A. Moreover, the remaining liquid volume could be easily confirmed by simply viewing the liquid cartridge 20 through the outer shaft 30 made of a visible material, resulting in a liquid vaporization container suitable for automotive use and other applications.

This liquid volatile 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, and the remaining liquid level is easily visible.
