(Spraying device)
In order to facilitate understanding of the liquid cartridge according to the embodiment of the present invention, a spray device (mist generator) will be described first. FIG. 1 is a schematic configuration diagram of a spray device according to an embodiment of the present invention. The spray device described below may be used with a fixed installation location, or may be used by a user with an arbitrary location.

  As shown in FIG. 1, the spray device 1000 is connected to a housing 1010, a liquid cartridge 100 disposed in the housing 1010, a vibration applying unit 1020 that applies vibration to the liquid cartridge 100, and a vibration applying unit 1020. And at least a power supply unit 1030 that supplies power to the vibration applying unit 1020. In the spray device 1000, the atomized liquid 130 is sprayed to the outside of the housing 1010 through a spray port 1015 provided in the housing 1010.

  Although the form of the housing | casing 1010 is not specifically limited, For example, you may have an elongate cylinder shape. As shown in FIG. 1, a control unit 1050 that controls the spray device 1000 is provided in the housing 1010, and the control unit 1050 includes a vibration applying unit 1020, a power supply unit 1030, and an input unit 1040. Are electrically connected to each other through the wiring portion 1060.

  Although details will be described later, the liquid cartridge 100 includes at least a container part 110 having a liquid storage part 112 and a mesh member 120 provided so as to cover the opening of the liquid storage part 112. A liquid 130 is stored in the liquid storage portion 112 of the container portion 110.

  The liquid cartridge 100 is installed such that the mesh member 120 is disposed at a position corresponding to the spray port 1015 of the housing 1010. The arrangement of the liquid cartridge 100 is appropriately set according to the spraying direction of the liquid 130. For example, when the spraying direction of the liquid 130 is a vertical direction, the mesh member 120 is arranged so as to face the vertical direction, and when the spraying direction of the liquid 130 is a horizontal direction, the mesh member 120 is horizontal. Arranged to face the direction. The housing 1010 is formed with an insertion port (not shown) so that the liquid cartridge 100 can be inserted. The position of the insertion port may be an upper part or a side part of the housing 1010. In this case, the liquid cartridge 100 is detachably mounted in the housing 1010 through the insertion port.

  The liquid 130 stored in the liquid cartridge 100 is atomized by predetermined means, passes through the mesh member 120, and is sprayed from the spray port 1015 to the outside of the housing 1010. FIG. 1 shows an example in which the vibration applying unit 1020 vibrates the mesh member 120 and generates a minute mist using the vibration.

  The vibration applying unit 1020 has a function of atomizing the liquid 130 stored in the liquid cartridge 100 by applying vibration to the mesh member 120 with the electric power from the power supply unit 1030. In the present embodiment, vibration applying unit 1020 is arranged so as to contact mesh member 120. An example of the vibration applying unit 1020 is a piezoelectric element.

  In FIG. 1, the vibration applying unit 1020 is disposed so as to be in contact with the surface side of the mesh member 120 (the side opposite to the container unit 110), but is not limited thereto. For example, the form which arrange | positions the vibration provision part 1020 in contact with the back surface side (container part 110 side) of the mesh member 120, and provides a vibration to the mesh member 120 by this may be sufficient. Or the form which arrange | positions the vibration provision part 1020 in the bottom face side of the container part 110, and provides a vibration to the liquid 130 in the container part 110 by this may be sufficient.

  As the power supply unit 1030, for example, a battery such as a dry battery or a rechargeable battery can be used. When power supply unit 1030 is made of a rechargeable battery, charging may be performed by a household outlet or sunlight.

  The input unit 1040 turns on / off the power applied from the power supply unit 1030 to the vibration applying unit 1020 via the control unit 1050, and includes, for example, a known power switch. Note that the control unit 1050 is not necessarily an essential configuration, and the power supply unit 1030 and the vibration applying unit 1020 may be directly connected by the input unit 1040.

  Next, the mist generating mechanism of the spray device 1000 will be described with reference to FIGS. 1 and 2A to 2D. 2A to 2D are schematic views for explaining an example of a mist generating mechanism of the spray device 1000. FIG. 2A to 2D, a vibration applying unit 1020 such as a piezoelectric element is disposed on the inner side of the mesh member 120 from the position fixed to the container unit 110 and on the opposite side of the liquid 130. Yes.

  FIG. 2A is a diagram illustrating a state in which vibration is not applied to the mesh member 120, and the liquid 130 is in contact with the mesh member 120 due to the surface tension of the liquid 130. When the user presses an input unit 1040 such as a switch provided in the housing 1010, an “ON” signal is transmitted to the control unit 1050. The control unit 1050 supplies power from the power supply unit 1030 to the vibration applying unit 1020 in response to an “ON” signal from the input unit 1040. As a result, the vibration applying unit 1020 starts to vibrate.

  2B to 2D are views showing a state where vibration is applied to the mesh member 120 by the vibration applying unit 1020. FIG. In FIG. 2B, the mesh member 120 is displaced outward, and the liquid 130 is pulled outward due to the surface tension. In FIG. 2 (C), the mesh member 120 is again displaced so that the internal pressure of the liquid container 112 is increased, and the liquid 130 is pushed out. In FIG. 2D, the mesh member 120 is displaced inward, and the extruded liquid 130 is ejected into a spherical shape due to surface tension. By repeatedly applying vibration to the mesh member 120 by the vibration applying unit 1020 such as a piezoelectric element, mist can be generated continuously.

  In addition, the above is an example and the mist generating mechanism in the spray device 1000 is not limited to this. For example, a conventionally known ultrasonic mist generating mechanism can be applied. Further, the configuration may be such that not only vibration is applied to the mesh member 120 but also energy can be transmitted to the liquid 130 by the energy transmission means and the liquid 130 can be discharged through the mesh member 120. In this case, the liquid 130 ejected by the energy transmission means is ejected through the spray port 1015. As an example of such an energy transmission means, there can be mentioned, for example, a method of applying energy in a pulse manner such as a solenoid coil or a heat pulse.

(Container with mesh)
Hereinafter, a container with a mesh constituting a liquid cartridge according to an embodiment of the present invention will be described with reference to the drawings. FIG. 3 is a cross-sectional view of a container with a mesh according to an embodiment of the present invention.

And a plurality of through holes 122 of the mesh member 120 are located in a region (opening region 113) where the opening of the liquid storage portion 112 exists.

A. The container section container section 110 includes a liquid storage section 112 that is an inner chamber capable of storing the liquid 130. One end of the liquid storage portion 112 is opened, and the liquid 130 held in the liquid storage portion 112 is guided out of the container portion 110 through the opening. The container part 110 has a flange part 114 provided on the outer periphery of the liquid storage part 112, and the container part 110 and the mesh member 120 are joined via the flange part 114.

  The container part 110 includes a first resin layer 116 located on the mesh member 120 side (inner side), a second resin layer 118 located on the opposite side (outer side) of the mesh member 120, the first resin layer 116, and the second resin. And at least a first barrier layer 117 positioned between the layers 118. Further, the bonding layer 115 may be provided on the first resin layer 116 and on the opposite side of the first barrier layer 117.

  The first resin layer 116 may be, for example, a single layer of polyethylene terephthalate (PET), polycarbonate (PC), polystyrene (PS), or polypropylene (PP) or a laminate thereof. From the viewpoint of manufacturing at low cost, it is preferable to use PET. Although there is no restriction | limiting in the thickness of the 1st resin layer 116, For example, it can set in the range of 10 micrometers-1 mm.

  The first barrier layer 117 is a layer that prevents a gas such as oxygen from entering the liquid storage portion 112 from the outside. Further, the first barrier layer 117 can prevent the liquid 130 in the liquid storage unit 112 from evaporating and escaping to the outside. Preferably, metals such as Al, inorganic oxides such as SiOx, MgOx and AlOx, inorganic nitrides such as SiNx, inorganic oxynitrides such as SiOxNy, ethylene vinyl alcohol copolymer (EVOH), polyvinylidene chloride (PVDC) Resin such as nylon can be used. In order to obtain high water vapor impermeability, it is preferable to use an inorganic oxide, an inorganic nitride, or an inorganic oxynitride. Moreover, in order to produce a container at low cost, it is preferable to use an ethylene vinyl alcohol copolymer (EVOH). Although there is no restriction | limiting in the thickness of the 1st barrier layer 117, if it is a metal, it can set in the range of 1 micrometer-10 micrometers, for example, if it is an inorganic oxide, an inorganic nitride, and an inorganic oxynitride, for example, 2 nm- If it is resin, it can set in the range of 10 micrometers-1 mm, for example.

  The second resin layer 118 is the outermost layer, and can be made of substantially the same material as the first resin layer 116. That is, for example, a single layer of polyethylene terephthalate (PET), polycarbonate (PC), polystyrene (PS), or polypropylene (PP) or a laminate thereof can be used. Although there is no restriction | limiting in the thickness of the 2nd resin layer 118, For example, it can set in the range of 10 micrometers-1 mm.

  The bonding layer 115 is a layer for improving the bonding property between the container part 110 and the mesh member 120, and is preferably made of the same material as the mesh member 120. Examples of the material of the bonding layer 115 include polyethylene terephthalate (PET). Moreover, the thickness of the joining layer 115 can be set, for example in the range of 10 micrometers-1 mm. Note that when the first resin layer 116 and the mesh member 120 are made of the same material, the bonding layer 115 is not necessarily provided.

The oxygen permeability of the container part 110 is preferably 20 (ml / m ² · day · MPa) or less under the conditions of a temperature of 25 ° C. and a humidity of 65%. The oxygen permeability is a value based on JIS K-7126-2.

  For example, the container part 110 forms the first barrier layer 117 on the second resin layer 118, and then adheres the first resin layer 116 and the bonding layer 115 by dry lamination to obtain a laminated film. Can be produced by molding. In addition, the layer structure of said container part 110 is an illustration, and may contain another layer. If the container part 110 has a structure in which resin layers are laminated, it can be manufactured at low cost. In addition, the moisture permeability can be lowered and the influence of external moisture and the evaporation of the internal liquid can be prevented, so that deterioration of the liquid in the liquid cartridge can be suppressed.

B. Mesh member Mesh member 120 is disposed on one end side of container portion 110 so as to cover the opening of liquid storage portion 112. A large number of through holes 122 are formed in the mesh member 120, and the large number of through holes 122 are located in a region where the opening of the liquid storage portion 112 exists (opening region 113). Although there is no restriction | limiting in the material of the mesh member 120, For example, it can be set as the single layer or these laminated body of a polyethylene terephthalate (PET), a polycarbonate (PC), a polystyrene (PS), and a polypropylene (PP). There is no restriction | limiting in the thickness of the mesh member 120, It is good to set so that suitable rigidity may be acquired according to a material. For example, specific numerical values may be set in a range of 10 μm to 10 mm.

The size of the opening of the through-hole 122 can be appropriately set according to the degree of classification, and for example, it may be in the range of 1 to 50 μm. For example, when the lotion is atomized and diffused as a mist, the effect of penetrating the skin can be enhanced by setting the above numerical range. The sizes of the through holes 122 may be uniform, or the sizes of the holes may be non-uniform. The number of through holes 122 and the density of the through holes 122 are not limited, but may be in the range of 10 to 500 holes / mm ² , for example. In addition, the planar shape of the through hole 122 may be a polygon, an ellipse, or the like in addition to a circle. Further, the size of the opening of the through hole 122 may be the same on the front surface and the back surface of the mesh member 120 or may be different from each other. For example, in the example shown in FIG. 3, the size of the opening of the through hole 122 is larger on the back surface side (liquid storage portion 112 side) than on the front surface side.

  The mesh member 120 and the container 110 described above can be integrated by, for example, direct bonding or bonding with an adhesive. In the direct bonding, for example, when the mesh member 120 and the bonding layer 115 of the container 110 (the first resin layer 116 when the bonding layer 115 is not provided) are made of the same material, an ultrasonic fusion method is used. Both can be joined and fixed using. In joining with an adhesive, an appropriate adhesive may be used in consideration of the material of the mesh member 120 and the material of the container part 110. For example, a heat sealant that melts by heating and solidifies by cooling may be used.

(Liquid cartridge)
A liquid cartridge is configured by filling the liquid container of the mesh-equipped container with liquid. Hereinafter, the liquid cartridge will be described with reference to FIGS. 4 and 5. FIG. 4 is a perspective view of a liquid cartridge according to an embodiment of the present invention. 5 is a cross-sectional view of the liquid cartridge according to the embodiment of the present invention, and is a cross-sectional view taken along the line II in FIG.

  4 and 5, the liquid cartridge 100 is configured by filling the liquid 130 in the liquid storage portion 112 of the mesh-equipped container 10 as described above. Such a liquid cartridge 100 includes a container part 110 having a liquid storage part 112 and a mesh member 120 provided so as to cover an opening of the liquid storage part 112, and a liquid 130 is stored in the liquid storage part 112. ing. In addition, since the structure of the container part 110 and the mesh member 120 was demonstrated using FIG. 3, detailed description is abbreviate | omitted here.

  Such a liquid cartridge 100 preferably further includes a seal member 150 that seals the liquid 130 on the mesh member 120 in order to prevent deterioration of the filled liquid 130 and liquid leakage to the outside. The seal member 150 includes a third resin layer 151 located on the mesh member 120 side (inside), a fourth resin layer 153 located on the opposite side (outside) of the mesh member 120, the third resin layer 151, and the fourth resin layer 151. At least a second barrier layer 152 located between the resin layer 153 and the resin layer 153 is included.

  The third resin layer 151 can be, for example, a single layer of polyethylene terephthalate (PET), polycarbonate (PC), polystyrene (PS), or polypropylene (PP) or a laminate thereof. From the viewpoint of manufacturing at low cost, it is preferable to use PET. The thickness of the 3rd resin layer 151 can be set, for example in the range of 10 micrometers-1 mm. The third resin layer 151 is a layer bonded to the mesh member 120 and is preferably made of the same material as the mesh member 120.

  The second barrier layer 152 is a layer that prevents a gas such as oxygen from entering the liquid storage unit 112 from the outside. Further, the second barrier layer 152 can prevent the liquid 130 in the liquid storage unit 112 from evaporating and escaping to the outside. Preferably, metals such as Al, inorganic oxides such as SiOx, MgOx and AlOx, inorganic nitrides such as SiNx, inorganic oxynitrides such as SiOxNy, ethylene vinyl alcohol copolymer (EVOH), polyvinylidene chloride (PVDC) Resin such as nylon can be used. In order to obtain high water vapor impermeability, it is preferable to use an inorganic oxide, an inorganic nitride, or an inorganic oxynitride. Moreover, in order to produce a container at low cost, it is preferable to use an ethylene vinyl alcohol copolymer (EVOH). Although there is no restriction | limiting in the thickness of the 2nd barrier layer 152, if it is a metal, it can set in the range of 1 micrometer-10 micrometers, for example, if it is an inorganic oxide, an inorganic nitride, and an inorganic oxynitride, for example, 2 nm- If it is resin, it can set in the range of 10 micrometers-1 mm, for example.

  The fourth resin layer 153 is the outermost layer, and can be made of substantially the same material as the third resin layer 151. That is, for example, a single layer of polyethylene terephthalate (PET), polycarbonate (PC), polystyrene (PS), or polypropylene (PP) or a laminate thereof can be used. The thickness of the 4th resin layer 153 can be set in the range of 10 micrometers-1 mm, for example.

The oxygen permeability of the seal member 150 is preferably 20 (ml / m ² · day · MPa) or less under conditions of a temperature of 25 ° C. and a humidity of 65%. The oxygen permeability is a value based on JIS K-7126-2.

  The seal member 150 can be manufactured, for example, by forming the second barrier layer 152 on the third resin layer 151 and then bonding the fourth resin layer 153 by dry lamination to obtain a laminated film. Note that the layer structure of the seal member 150 described above is an example, and may include another layer. If the sealing member 150 has a structure in which resin layers are laminated, it can be manufactured at low cost. In addition, the moisture permeability can be lowered and the influence of external moisture and the evaporation of the internal liquid can be prevented, so that deterioration of the liquid in the liquid cartridge can be suppressed.

  The seal member 150 is preferably disposed so as to be peelable from the mesh member 120. As a method of joining the seal member 150 to the mesh member 120, a method of joining the seal member 150 to the mesh member 120 using a weak adhesive, a seal member 150 and the mesh member 120 using an adhesive such as a heat seal agent. There can be mentioned a method of controlling the adhesion area so that is partially adhered. In particular, when the mesh member 120 and the third resin layer 151 are made of the same material, they can be bonded and fixed using an ultrasonic fusion method. Furthermore, it is more preferable that the first resin layer 116 of the container part 110, the mesh member 120, and the third resin layer 151 of the seal member 150 are all made of the same material. By making these materials the same, direct bonding can be performed using an ultrasonic fusion method, and the sealing performance at the side surface of the liquid cartridge 100 can be improved.

  Various methods of filling the liquid container 112 into the liquid container 112 of the mesh-equipped container 10 are conceivable. For example, after injecting the liquid 130 into the liquid storage part 112, the mesh member 120 is joined to the container part 110, or the other end (bottom surface) of the container part 110 is joined after the mesh member 120 is joined to the container part 110. For example, a method of injecting the liquid 130 from a side injection hole (not shown) and sealing the injection hole can be considered. The liquid 130 filled in the liquid container 112 of the mesh-equipped container 10 is not particularly limited as long as it is in a liquid state at the time of use, and examples thereof include skin lotion, medicine, and fragrance.

  As the liquid 130 filled in the liquid storage part 112 of the container part 110, a liquid that does not contain a preservative may be used. Here, the “preservative” refers to an additional component added to maintain the liquid in an intended state, such as a preservative that suppresses the growth of microorganisms, an antioxidant that suppresses deterioration due to oxygen, and the like. Is included. For example, in cosmetics, as preservatives, benzoic acid, sodium benzoate, isopropylmethylphenol, chlorhexidine hydrochloride, hydrogen peroxide, chlorhexidine gluconate, chlorhexidine, salicylic acid, sodium salicylate, sink pyrithione, sorbic acid, potassium sorbate, Dehydroacetic acid, sodium dehydroacetate, phenol, resorcin, paraoxybenzoates (parabens), phenoxyethanol, and the like may be added. Of these preservatives, those that have little impact on the user are selected and used by testing, etc., but the preservatives cannot be said to have no irritation on the skin, and are particularly sensitive to irritation. It is thought that cosmetics with no preservatives are preferred by the person. The liquid 130 filled in the liquid cartridge 100 according to the present embodiment may not substantially contain the preservative. “Substantially free” means that it does not exclude an embodiment in which a smaller amount of the compound is included than the degree of achieving the purpose of antiseptic and antioxidant. In a conventional spraying device, a mesh is provided on the spraying device side, and a container previously filled with a liquid is attached to the spraying device by a user. Therefore, with conventional spray devices, it is difficult to use up the liquid in the container, and there is a risk that the old liquid may remain in the container or the liquid used in the mesh holes may remain. There were obstacles to using liquids that did not contain any charge. In the liquid cartridge according to the present invention, the mesh member and the container are integrated, and the container is filled with a new liquid, so that a fresh liquid and a new mesh can be used and stored every time it is used. Even if a liquid that does not substantially contain a charge is used, there is little possibility of causing trouble in use. Further, as described above, since the container part 110 includes the first barrier layer 117 and the sealing member 150 includes the second barrier layer 152, even the liquid 130 substantially not containing the preservative is deteriorated. Can be suppressed.

(Liquid cartridge package)
