[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in Fig. 1 to Fig. 4, the sprayer 100 according to the first embodiment has a main body 20 for mounting the liquid medicine capsule 10, and a cover body 30 equipped with a piezoelectric element 32. The sprayer 100 is an example of a "diffusion device" as described in the claims of the present application, the liquid medicine capsule 10 is an example of a "sealed body" as described in the claims of the present application, and the piezoelectric element 32 is an example of a "diffusion means" as described in the claims of the present application.

[0015] 5, the liquid medicine capsule 10 to be attached to the main body 20 has a cup 12, an impregnated body 14, and a sealing material 16. The cup 12 is an example of the "container" described in the claims of the present application.

[0016] The cup 12 has a substantially rectangular opening 12a at its upper end, and a substantially rectangular annular flange 12b on the outside of the opening 12a. The cup 12 has a storage section 12d whose cross section gradually becomes smaller from the opening 12a toward the bottom 12c. The storage section 12d has a substantially rectangular cross section perpendicular to the depth direction from the opening 12a toward the bottom 12c. The cup 12 can be made of a resin material such as polystyrene (PS), polypropylene (PP), polyethylene terephthalate (PET), polyvinyl chloride (PVC), or polyethylene (PE). The opening 12a of the cup 12 has a size and shape that allows the impregnated body 14 to be inserted and allows the insertion of a push-in protrusion 35 of the lid 30, which will be described later.

[0017] The impregnated body 14 is impregnated with a liquid medicine such as an aromatic, a deodorant, or an insecticide. The impregnated body 14 can be integrally molded, for example, by pulp molding. Pulp molding has a high degree of freedom in shape compared to, for example, polyester fibers formed into a rod shape, and is easy to mold into a desired shape. In addition, by adjusting the density of the pulp, the pulp molding can create parts with high rigidity and parts that can be impregnated with a larger amount of liquid medicine.

[0018] The impregnated body 14 is contained and placed in the cup 12 with the tip 14a thereof being impregnated with the chemical solution and disposed in the opening 12a. The bottom surface 14b of the impregnated body 14 contacts the inner surface of the bottom 12c of the cup 12. In this embodiment, a case where the entire amount of the chemical solution is impregnated into the impregnated body 14 will be described, but the chemical solution may be contained in the containing portion 12d of the cup 12 in addition to the chemical solution impregnated into the impregnated body 14. The structure of the impregnated body 14 and the manufacturing method thereof will be described in detail later.

[0019] The sealing material 16 seals the opening 12a of the cup 12 after the impregnated body 14 impregnated with the chemical solution is housed therein, or after the impregnated body 14 and the chemical solution are housed therein. With the opening 12a sealed, the tip 14a of the impregnated body 14 may be in contact with the inner surface of the sealing material 16, or may be slightly spaced apart from the inner surface of the sealing material 16. The sealing material 16 is made of a material that is not permeable to the chemical solution. In addition, the sealing material 16 is made of a material that can be easily broken by the tip 14a of the impregnated body 14 when pressed against the tip 14a, as described below.

[0020] The sealing material 16 may be, for example, a heat seal material provided on the inner surface of an aluminum foil on the cup 12 side. In this case, the sealing material 16 is fixed to the flange portion 12b of the cup 12 by heat welding. The outer peripheral edge of the sealing material 16 may be wrapped around the outer peripheral edge of the flange portion 12b of the cup 12 to the underside of the flange portion 12b.

[0021] The main body 20 of the sprayer 100 has a substantially cylindrical outer shape. The main body 20 has an attachment section 22 on its upper surface 20a for detachably attaching the above-mentioned liquid medicine capsule 10. The attachment section 22 has a shape in which the upper surface 20a is recessed toward the inside of the main body 20. The attachment section 22 is located at a position shifted from the center of the main body 20 toward the hinge 25 side described later. The attachment section 22 has a recess 22a with a substantially rectangular cross section having a substantially rectangular opening 21 for receiving the storage section 12d of the cup 12 of the liquid medicine capsule 10, and a substantially rectangular annular step section 22b around the opening 21.

[0022] The recess 22a may have any shape as long as it can receive the storage portion 12d of the cup 12 of the liquid medicine capsule 10. The flange portion 12b of the cup 12 of the liquid medicine capsule 10 is fitted into the step portion 22b. The step portion 22b has an outer periphery that is substantially the same shape as the outer periphery of the flange portion 12b and is slightly larger than the flange portion 12b. The depth of the recess 22a is such that the bottom 12c of the cup 12 does not reach the bottom of the recess 22a slightly when the flange portion 12b is fitted into the step portion 22b.

[0023] The main body 20 has three operation buttons 24 on its peripheral surface 20b. The three operation buttons 24 are located on the front side of the main body 20 opposite a hinge 25 described below. The operation buttons 24 include a button 24a for turning on / off the power supply to the piezoelectric element 32, a button 24b for switching the operation mode of the piezoelectric element 32, and a button 24c for turning on a lamp 202 (FIG. 7) built into the main body 20. The three operation buttons 24 can be operated regardless of whether the cover 30 is open or closed.

[0024] The lid body 30 has a substantially disk-shaped outer shape with substantially the same diameter as the main body 20. The lid body 30 is rotatably connected to the main body 20 via a hinge 25. The hinge 25 connects the outer periphery of the lid body 30 to the outer periphery of the upper surface 20a side of the main body 20 on the radial opposite side of the front surface where the operation button 24 is located. The lid body 30 is rotatable between a closed position shown in FIG. 1 in which the drug solution capsule 10 attached to the attachment part 22 of the main body 20 is covered, and an open position shown in FIG. 3 in which the attachment part 22 on the upper surface 20a of the main body 20 is opened. On the radial opposite side of the hinge 25, there is a latch mechanism (not shown) that fixes the main body 20 and the lid body 30 when the lid body 30 is placed in the closed position.

[0025] The cover 30 has a generally disk-shaped inner plate 31 having an inner surface 31a that faces the upper surface 20a of the main body 20 when the cover 30 is in the closed position. The cover 30 has a generally cylindrical recess 34 therein that houses a piezoelectric element 32. The recess 34 has a shape in which the inner plate 31 of the cover 30 is recessed from the inside. The recess 34 is located at a position offset from the center of the cover 30 toward the hinge 25 so as to face the mounting portion 22 of the main body 20.

[0026] The piezoelectric element 32 comprises a substantially circular mesh 32a having a plurality of spray holes (not shown) and a substantially annular peripheral portion 32b that holds the outer periphery of the mesh 32a. The peripheral portion 32b is a plate-shaped piezoelectric ceramic having electrodes on both sides. The piezoelectric element 32 has an outer diameter smaller than the inner diameter of the recess 34. The piezoelectric element 32 is well known, and therefore a detailed description thereof will be omitted here.

[0027] At the bottom of the recess 34, there is a substantially circular through hole 34a having a diameter larger than the outer diameter of the mesh 32a of the piezoelectric element 32 and smaller than the outer diameter of the peripheral portion 32b. By providing the recess 34 in the inner plate portion 31 of the lid body 30, a substantially annular pushing protrusion 35 protruding outward from the lid body 30 is formed. At the center of the pushing protrusion 35, there is the above-mentioned through hole 34a. The pushing protrusion 35 is an example of the "seal piercing member" described in the claims of this application. The pushing protrusion 35 is a protrusion for pushing the sealing material 16 into the cup 12 at a position away from the tip 14a of the impregnated body 14 enclosed in the drug solution capsule 10.

[0028] The top wall 38 of the lid 30 facing the recess 34 has a substantially circular spray hole 39 penetrating the top wall 38. The spray hole 39 is located offset toward the hinge 25 from the center of the lid 30. In other words, the recess 34, the through hole 34a, the push-in protrusion 35, and the spray hole 39 of the lid 30 are arranged substantially coaxially with the central axis passing through the tip 14a of the impregnated body 14 enclosed in the drug solution capsule 10 attached to the attachment portion 22 of the main body 20.

[0029] The cover 30 also includes an elastic member 36 that presses the piezoelectric element 32 against the bottom of the recess 34. The elastic member 36 may be a coil spring arranged concentrically with the through-hole 34a, or may be a sponge or rubber with holes. The elastic member 36 is located opposite the peripheral portion 32b of the piezoelectric element 32.

[0030] If the lid 30 is closed in the closed position without the liquid medicine capsule 10 being attached to the attachment portion 22 of the main body 20, the elastic member 36 presses the peripheral portion 32b of the piezoelectric element 32, causing the peripheral portion 32b to come into contact with the bottom of the recess 34, as shown in Fig. 6. In this state, the mesh 32a of the piezoelectric element 32 faces the recess 22a of the main body 20 via the through hole 34a of the recess 34 of the lid 30, and the opposite side of the piezoelectric element 32 faces the spray hole 39.

[0031] Here, a preparation operation before using the above-mentioned sprayer 100 will be described. First, as shown in Fig. 3, the lid 30 is placed in the open position and the liquid medicine capsule 10 is attached to the attachment part 22 of the main body 20. Fig. 4 shows the state in which the liquid medicine capsule 10 is attached to the attachment part 22. When the liquid medicine capsule 10 is attached to the attachment part 22 and the container part 12d of the cup 12 of the liquid medicine capsule 10 is inserted into the recess 22a of the attachment part 22, the flange part 12b of the cup 12 fits into the step part 22b of the attachment part 22. In this state, horizontal movement of the liquid medicine capsule 10 relative to the main body 20 can be restricted.

[0032] After the liquid medicine capsule 10 is attached to the attachment portion 22, the lid body 30 is placed in the closed position as shown in Figures 1 and 2, and the lid body 30 is fixed to the main body 20. When the lid body 30 is closed in the closed position with the liquid medicine capsule 10 attached to the attachment portion 22, the pushing protrusion 35 of the lid body 30 pushes the sealing material 16 at a position displaced from the tip 14a of the impregnated body 14 and is pushed into the liquid medicine capsule 10, and the sealing material 16 is broken.

[0033] When the sealant 16 of the drug solution capsule 10 is broken by the pushing convex portion 35, the tip 14a of the impregnated body 14 housed in the cup 12 protrudes into the recess 34 of the lid body 30 through the through hole 34a of the pushing convex portion 35, and presses the mesh 32a of the piezoelectric element 32 from below. When the mesh 32a is pressed upward by the tip 14a of the impregnated body 14, the piezoelectric element 32 is slightly pressed toward the upper side of the lid body 30 against the restoring force of the elastic member 36, and a small gap is formed between the bottom of the recess 34 and the peripheral portion 32b of the piezoelectric element 32. In this state (the state shown in FIG. 2), the elastic member 36 generates a restoring force in a direction to press the mesh 32a of the piezoelectric element 32 against the tip 14a of the impregnated body 14.

[0034] In other words, the height of the impregnated body 14, the protruding height of the push-in protrusion 35, the depth of the cup 12 of the liquid medicine capsule 10, the depth of the step 22b of the attachment part 22, etc. are set to values ​​that allow the tip 14a of the impregnated body 14 to be just pressed against the mesh 32a of the piezoelectric element 32 with the lid body 30 fixed in the closed position. In other words, adjustments are made by the elastic force of the elastic member 36 so that the tip 14a of the impregnated body 14 and the mesh 32a of the piezoelectric element 32 do not come into contact even slightly due to dimensional variations of each part or vibration during use.

[0035] 7 is a block diagram showing the driving unit 200 of the above-mentioned sprayer 100. The driving unit 200 has a controller 201, three buttons 24a, 24b, and 24c, a display unit 206 that displays the operation mode and the like, and a power supply unit 208 connected to a power source 204. The power source 204 can be a rechargeable battery or a dry cell that can be charged from a commercial power source.

[0036] After the preparatory operations described above, when button 24b is operated to select an operation mode for piezoelectric element 32 and button 24a is turned ON, controller 201 operates power supply unit 208 in the selected operation mode and supplies power to piezoelectric element 32 according to the operation mode. This causes piezoelectric element 32 to vibrate, and the medicinal liquid supplied to mesh 32a of piezoelectric element 32 via tip 14a of impregnated body 14 is atomized. The medicinal liquid atomized by the vibration of piezoelectric element 32 is sprayed through spray hole 39 of lid body 30.

[0037] The controller 201 may include an adjustment unit for adjusting the voltage and frequency of power supplied to the piezoelectric element 32. By changing the frequency at which the piezoelectric element 32 is driven, the amount of the medicinal liquid sprayed per certain time period can be changed.

[0038] Hereinafter, the impregnated body 14 enclosed in the liquid medicine capsule 10 will be described in detail with reference to FIGS. 8 to 13 as well as FIG. As shown in Fig. 5, the impregnated body 14 has a structure in which an outer member 42 is layered on the outside of an inner member 41. The inner member 41 is an example of a "first member" as defined in the claims of the present application, and the outer member 42 is an example of a "second member" as defined in the claims of the present application.

[0039] 5, the impregnated body 14 is sealed in the drug solution capsule 10 in a state in which the outer member 42 is layered on the outside of the inner member 41 and impregnated with the drug solution. When the inner member 41 and the outer member 42 are layered as shown in the figure, the inner member 41 and the outer member 42 are in contact with each other over a sufficiently large surface, so that the drug solution impregnated in the inner member 41 can be supplied to the outer member 42.

[0040] The impregnated body 14 of this embodiment needs to be impregnated with a predetermined amount of drug solution and needs to have a rigidity sufficient to break through the sealing material 16 of the drug solution capsule 10. To facilitate impregnation with the drug solution, it is desirable to soften the pulp by lowering its density to a certain degree, but to increase the rigidity, it is necessary to harden the pulp by increasing its density to a certain degree. For this reason, in this embodiment, the pulp density of the outer member 42 having the tip 14a that breaks through the sealing material 16 is increased to increase the rigidity, and the pulp density of the inner member 41 for impregnating the drug solution is reduced to make it soft.

[0041] 8 is a perspective view of the state in which the impregnated body 14 impregnated with the chemical solution is accommodated in the accommodation portion 12d of the cup 12 (before the opening 12a is sealed with the sealing material 16). When accommodated in the accommodation portion 12d of the cup 12, the bottom surface 14b of the impregnated body 14 contacts the inner surface of the bottom portion 12c of the cup 12. The bottom surface 14b of the impregnated body 14 is formed in a substantially rectangular shape that is slightly smaller than the inner surface of the bottom portion 12c of the cup 12. In this state, the tip 14a of the impregnated body 14 is located at the opening 12a of the cup 12, as shown in FIG.

[0042] The inner member 41 and the outer member 42 of the impregnated body 14 are connected via two hinges 43 as shown in FIG. 9. The number of hinges 43 is not limited to two and can be determined arbitrarily. FIG. 9 shows the impregnated body 14 before being impregnated with a chemical solution. The impregnated body 14 of this embodiment is formed by forming a pulp mold 40 shown in FIG. 10 and FIG. 11 in which the inner member 41 and the outer member 42 are integrally connected by the hinge 43, and then folding this pulp mold 40 in half at the hinge 43 to overlap the inner member 41 inside the outer member 42. Therefore, the tip 14a of the impregnated body 14 is in the outer member 42, and the bottom surface 14b of the impregnated body 14 is in the inner member 41.

[0043] Fig. 10 is a perspective view of the pulp mold 40 seen from one side, and Fig. 11 is a perspective view of the pulp mold 40 seen from the other side. Fig. 12 is a plan view of the pulp mold 40 of Fig. 10 seen from the direction of arrow F12. Fig. 13 is a cross-sectional view of the pulp mold 40 of Fig. 12 cut along F13-F13.

[0044] The inner member 41 of the pulp mold 40 has a substantially rectangular plate-like portion 41a having the above-mentioned bottom surface 14b, and a substantially solid, substantially conical bulging portion 41b formed by bulging the center of the plate-like portion 41a toward the other surface 40b side of the pulp mold 40 (the back side of the paper in FIG. 12). In the center of the bottom surface 14b of the plate-like portion 41a, there is a substantially circular recess 41c that is slightly recessed in the same direction as the bulging direction of the bulging portion 41b. The recess 41c is formed coaxially with the bulging portion 41b. The height of the bulging portion 41b in the bulging direction is greater than half the height of the impregnated body 14. The bulging portion 41b is formed to a size and shape that fits into a recess 42c of a bulging portion 42b of the outer member 42, which will be described later, when the inner surface 411 of the plate-like portion 41a is in contact with an inner surface 421 of the outer member 42, which will be described later, and the two are overlapped (the state shown in FIG. 9). The bulging portion 41b of the inner member 41 is an example of the "first bulging portion" set forth in the claims of the present application.

[0045] The outer member 42 has a substantially rectangular plate-like portion 42a having substantially the same size and thickness as the plate-like portion 41a of the inner member 41, and a substantially conical bulging portion 42b formed by bulging the center of the plate-like portion 42a toward one surface 40a of the pulp mold 40 (the front side of the paper in FIG. 12). The bulging portion 42b of the outer member 42 is slightly larger than the bulging portion 41b of the inner member 41 described above, and its height in the bulging direction is substantially the same as the height of the impregnated body 14. A recess 42c having a size capable of accommodating and disposing the bulging portion 41b of the inner member 41 described above is formed inside the bulging portion 42b. Unlike the bulging portion 41b of the inner member 41 described above, the thickness of the bulging portion 42b is substantially constant, and the bulging portion 42b is pressed tightly to be thin. The bulging portion 42b of the outer member 42 is an example of the "second bulging portion" described in the claims of the present application.

[0046] Next, a method for producing the above-mentioned pulp mold 40, that is, a method for producing the impregnated body 14, will be described with reference to FIGS. A mold 50 shown in Fig. 14 is used to manufacture the pulp mold 40. The mold 50 is, for example, an aluminum plate having a certain thickness that has been shaped. The mold 50 has a concave surface 50a whose shape corresponds to the surface shape of the other surface 40b of the pulp mold 40. The mold 50 has a large number of fine water suction holes (not shown) that penetrate the aluminum plate over the entire concave surface 50a. A mesh material 52 that is at least finer than the water suction holes is attached to the concave surface 50a of the mold 50 to prevent the pulp from being sucked in through the water suction holes.

[0047] The raw material liquid of the pulp mold 40 is, for example, viscous liquid obtained by dispersing pulp made of finely ground plant fibers such as wood in water. Pulp used as the raw material includes, but is not limited to, chemical pulp, semi-chemical pulp, mechanical pulp, non-wood fiber pulp, and recycled paper pulp. One type of pulp may be used alone, or two or more types may be used in combination. Furthermore, the wood used as the raw material for the pulp may be softwood or hardwood, or these may be used in combination.

[0048] The liquid is scooped up by the concave surface 50a of the mold 50 described above, and the liquid is sucked from the opposite side of the concave surface 50a of the mold 50 through a number of water suction holes. As a result, the water in the liquid is sucked through the water suction holes, and the pulp in the liquid is layered on the mesh material 52. The state of the pulp P after dehydration is shown in FIG. 15. When the liquid in the concave surface 50a of the mold 50 is sucked, the liquid flows in large amounts into the deep parts of the concave surface 50a due to the fluidity of the liquid, and the liquid adheres thinly to the shallow parts and the raised parts. As a result, the thickness of the pulp P in the concave surface 50a after dehydration has a distribution as shown in FIG. 15.

[0049] After dehydration, the pulp P in Fig. 15 is placed in another mold (not shown) and transferred to a press (not shown) where it is heated and pressed, shaped into the shape shown in Fig. 13, and then dried. When pulp P after dehydration is molded in a press mold, if the chamber of the mold is designed to be thinner than the thickness of the pulp P before molding, the pulp density of that part can be increased and that part can be molded hard. Conversely, if the chamber of the mold is designed to be thicker than the thickness of the pulp P before molding, or to be the same thickness, the pulp density of that part can be reduced and that part can be molded softly.

[0050] After pressing, the pulp P is removed from the pressing die and dried again to complete the pulp mold 40. The cross-sectional shape of the completed pulp mold 40 is shown in FIG. 13. Looking at the cross-section of the pulp mold 40, it can be seen that the inner member 41 is thicker and has a larger volume than the outer member 42. As described above, the thickness of the pulp P before molding has a distribution as shown in FIG. 15. In addition, since the thicknesses of the chambers of the pressing die are different between the inner member 41 and the outer member 42, the inner member 41 has a larger amount of pulp and is thicker than the outer member 42, making it softer with a lower density. In addition, the outer member 42 has a smaller amount of pulp and is thinner than the inner member 41, making it denser and more rigid than the inner member 41.

[0051] Therefore, the impregnated body 14, which is made by folding the pulp mold 40 in half at the hinge 43 and layering the outer member 42 on the outside of the inner member 41, can increase the rigidity of the tip 14a, and can be impregnated with a large amount of chemical solution by the relatively soft inner member 41. Also, the impregnated body 14 can have the bulging portion 41b of the inner member 41 contact the recess 42c of the outer member 42 over a wide surface area, and the chemical solution impregnated in the inner member 41 can be absorbed by the outer member 42 and supplied to the tip 14a.

[0052] As described above, according to this embodiment, the bulging portion 41b of the relatively soft inner member 41 can be accommodated in the recess 42c of the highly rigid outer member 42 having the tip 14a, thereby bringing the two into contact with each other. This allows the inner member 41 to be impregnated with a large amount of medicinal liquid and supplied to the tip 14a of the outer member 42, and the sealing material 16 of the medicinal liquid capsule 10 can be easily broken by the tip 14a of the impregnated body 14.

[0053] Furthermore, according to this embodiment, the pulp mold 40 in which the inner member 41 and the outer member 42 are connected by the hinge 43 can be molded as a single unit, and the hardness of the inner member 41 and the outer member 42 can be made different. Therefore, compared to the case in which the inner member 41 and the outer member 42 are molded separately and then stacked together, the number of steps for manufacturing the impregnated body 14 can be reduced, and the manufacturing cost of the impregnated body 14 can be reduced.

[0054] Fig. 16 is a cross-sectional view of an impregnated body 70 according to another embodiment, cut along a plane including a central axis passing through the tip 70a. Fig. 17 is a perspective view of the inner member 71 of the impregnated body 70 seen from the outer member 72 side, and Fig. 18 is a perspective view of the inner member 71 of Fig. 17 seen from the bottom surface 70b side. Fig. 19 is a perspective view of the outer member 72 of the impregnated body 70 seen from the tip 70a side, and Fig. 20 is a perspective view of the outer member 72 of Fig. 19 seen from the recess 72c side. This impregnated body 70 does not have a hinge 43, and has a structure in which the inner member 71 and the outer member 72 are separate bodies, and the other structure is generally the same as that of the impregnated body 14 described above.

[0055] The inner member 71 is an example of a "first member" as defined in the claims, and has a substantially rectangular plate-shaped portion 71a, a bulging portion 71b, and a recess 71c. The plate-shaped portion 71a corresponds to the plate-shaped portion 41a of the inner member 41 of the impregnated body 14, the bulging portion 71b corresponds to the bulging portion 41b, and the recess 71c corresponds to the recess 41c. The bulging portion 71b of the inner member 71 is an example of a "first bulging portion" as defined in the claims.

[0056] The outer member 72 is an example of a "second member" as defined in the claims, and has a substantially rectangular plate-like portion 72a, a bulging portion 72b, and a recess 72c. The plate-like portion 72a corresponds to the plate-like portion 42a of the outer member 42 of the impregnated body 14, the bulging portion 72b corresponds to the bulging portion 42b, and the recess 72c corresponds to the recess 42c. The bulging portion 72b of the outer member 72 is an example of a "second bulging portion" as defined in the claims.

[0057] The inner member 71 and the outer member 72 are each formed as a separate pulp mold. That is, like the impregnated body 14 in the above-mentioned embodiment, the inner member 71 and the outer member 72 are each formed by pouring a pulp raw material liquid into a metal mold for dehydration, dehydrating the pulp, and then pouring the dehydrated pulp into another metal mold for pressing, and molding the pulp by heating and pressurizing. For this reason, the amount of pulp used to mold the inner member 71 can be increased to lower the pulp density and make it softer, and the amount of pulp used to mold the outer member 72 can be decreased to increase the pulp density and make it harder.

[0058] The inner member 71 and the outer member 72 formed separately as described above are formed by overlapping the inner surface 711 of the plate-shaped portion 71a of the inner member 71 with the inner surface 721 of the plate-shaped portion 72a of the outer member 72, as shown in Figure 16, and fitting the bulging portion 71b of the inner member 71 into the recess 72c of the outer member 72, thereby forming the impregnated body 70.

[0059] In the impregnated body 70 according to another embodiment, the inner member 41 and the outer member 42 are not integrally formed as in the above-mentioned impregnated body 14, and therefore the volume of the inner member 71 and the volume of the outer member 72 can be formed to a desired size. Therefore, the impregnated body 70 can be impregnated with a sufficient amount of chemical solution by increasing the volume of the inner member 71.

[0060] FIG. 21 shows a volatilization device 110 according to a second embodiment. The volatilization device 110 has a volatilization body 60 instead of the piezoelectric element 32 of the sprayer 100 of the first embodiment. In addition, the cover body 30 of the volatilization device 110 has a plurality of volatilization holes 62 instead of the spray hole 39. In addition, the volatilization device 110 does not have a drive unit 200. The other configuration functions in the same way as the sprayer 100 of the first embodiment. Therefore, here, the configuration that functions in the same way as the sprayer 100 of the first embodiment described above is given the same reference numerals and detailed description thereof is omitted.

[0061] The volatilizer 60 has a substantially circular convex portion 61 that fits into the recess 34 of the inner plate portion 31 of the lid body 30. No external pressure is applied to the volatilizer 60, and it is in a state where it can move up and down between the inner plate portion 31 of the lid body 30 and the top wall 38. The volatilizer 60 can be formed from a material that can absorb the chemical solution, for example, a porous material such as chemical fiber including at least one selected from the group consisting of polyester fiber, polyurethane fiber, acrylic fiber, melamine fiber, polyimide fiber, polyamide fiber, phenol fiber, epoxy fiber, nylon fiber, vinylon fiber, polyacetal fiber, polyethylene fiber, polypropylene fiber, vinyl chloride fiber, and acetate fiber, pulp, felt, natural fiber bundle, and foamed synthetic resin, or a material that is a mixture of two or more of these materials.

[0062] When using this volatilization device 110, the liquid medicine capsule 10 is attached to the attachment portion 22 of the main body 20, and the lid body 30 is rotated to the closed position. Then, the pushing convex portion 35 of the lid body 30 is pushed into the opening 12a of the cup 12 of the liquid medicine capsule 10, and the sealing material 16 is pressed against the tip 14a of the impregnated body 14, breaking the sealing material 16. Then, the tip 14a of the impregnated body 14 pushes up the convex portion 61 of the volatilization body 60, and the volatilization body 60 is pressed against the tip 14a of the impregnated body 14 by its own weight.

[0063] In this state (the state shown in FIG. 21 ), the medicinal liquid impregnated in the impregnated body 14 is sucked up by the volatilizer 60, and the medicinal liquid is volatilized from the volatilizer 60. The medicinal liquid volatilized from the volatilizer 60 is volatilized to the outside through a plurality of volatilization holes 62 in the top wall 38 of the lid 30.

[0064] As described above, according to the sprayer 100 of the first embodiment and the volatilization device 110 of the second embodiment, the medicinal liquid capsule 10 is attached to the attachment portion 22 and the lid body 30 is closed in the closed position, and the medicinal liquid can be diffused or volatilized without the need to peel off the sealing material 16 of the medicinal liquid capsule 10. In addition, since the medicinal liquid capsule 10 contains the impregnated body 14 (70) in the cup 12, the configurations of the sprayer 100 and the volatilization device 110 can be simplified, and the sprayer 100 and the volatilization device 110 can be manufactured inexpensively.

[0065] In addition, in the sprayer 100 of the first embodiment and the volatilization device 110 of the second embodiment, since the liquid medicine capsule 10 is used, there is no need for wasteful components that become unnecessary after removal, such as the cap of the medicine container of the medicine atomizer of Patent Document 1. Therefore, a mold for manufacturing the cap is not required, and the liquid medicine capsule 10 can be manufactured inexpensively, and the selling price can be suppressed.

[0066] In addition, since the impregnated body 14(70) is sealed in the drug solution capsule 10 with the tip 14a(70a) of the impregnated body 14(70) positioned at the opening 12a of the cup 12, the volatilization of the drug solution can be started via the impregnated body 14(70) simply by puncturing the sealing material 16 with the tip 14a(70a) of the impregnated body 14(70). In other words, the drug solution capsule 10 can function alone as a volatilization device.

[0067] In the above-mentioned first and second embodiments, the seal material 16 of the liquid medicine capsule 10 is made of aluminum foil with a heat seal material on the inner surface, but for example, a material such as that used for a rubber balloon may be stretched and attached to the flange portion 12b of the cup 12. In this case, a sharp needle or the like may be used as the seal piercing member, and the device configuration can be further simplified.

[0068] The present invention has been described above based on an embodiment, but the present invention is not limited to the above-described embodiment or its modified examples, and it is needless to say that various modifications and applications are possible within the scope of the gist of the present invention.
