Description

[Technical Field]

[0001] The present invention relates to a chemical container and a volatilization device equipped with the same. [Background technology]

[0002] Patent Document 1 discloses a conventional drug container (referred to as a drug volatilizer in Patent Document 1). The drug volatilizer described in Patent Document 1 comprises a container for storing a drug and a flexible sheet layer that closes the opening of the container. The flexible sheet layer has a volatilization layer that volatilizes the drug and a rupture layer that is disposed between the volatilization layer and the container.

[0003] When pressure is applied from the outside of the volatilization layer, the rupture layer can rupture with a smaller elongation than the volatilization layer. Therefore, when pressure is applied from the outside of the volatilization layer to the drug volatilizer, the rupture layer bends along with the volatilization layer, but the rupture layer ruptures first, allowing the drug to escape. When the drug reaches the volatilization layer through the ruptured hole, it volatilizes from the volatilization layer and diffuses into the space where the drug container is placed.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2018-196581 Summary of the Invention [Problem to be solved by the invention]

[0005] In the drug volatilizer described in Patent Document 1, the flexible sheet layer is joined to the flange of the container. Specifically, the fracture layer overlaps one surface of the flange, and the volatilization layer is welded onto the fracture layer.

[0006] However, when welding the volatile layer onto the fracture layer, it is necessary to form a welding layer on both sides of the fracture layer in the thickness direction. Then, after the flange, fracture layer, and volatile layer are stacked together, it is necessary to heat the volatile layer from above. In this case, however, it is difficult for the heat to reach the welded portion between the fracture layer and the flange, which can result in poor welding.

[0007] The present invention has been made in consideration of the above circumstances, and aims to provide a drug container having a first membrane and a second membrane superimposed on the first membrane, in which the first membrane and the second membrane have appropriate bonding strength to the flange portion, and an evaporation device equipped with the same. [Means for solving the problem]

[0008] The drug container of the present disclosure has an opening surface on one side and comprises a storage section in which the drug is stored, a flange section provided along the outer periphery of the opening surface of the storage section, a first membrane joined to the flange section so as to close the opening surface, and a second membrane arranged on the outer surface of the first membrane, and the second membrane is joined to the surface of the flange section that is closer to the outer edge than the joining portion of the first membrane.

[0009] In the drug container of the present disclosure, it is preferable that a gap is present between the joint portion of the first film and the joint portion of the second film.

[0010] In the drug container of the present disclosure, the gap is preferably 1 mm or more and 3 mm or less.

[0011] In the drug container of the present disclosure, it is preferable that the joining portion of the first film and the joining portion of the second film of the flange portion are located on the same plane.

[0012] The volatilization device of the present disclosure comprises a drug container of the above-described aspect, a housing capable of accommodating the drug container, and a movable body having an operating part movable relative to the housing from a first position to a second position, wherein the movable body has a protruding part that breaks the first membrane via the second membrane when the operating part moves to the second position. [Effects of the Invention]

[0013] The drug container and the evaporation device equipped with the same of the present disclosure have the advantage that in a drug container having a first membrane and a second membrane, appropriate bonding strength of the first membrane and the second membrane to the flange portion can be obtained.

DETAILED DESCRIPTION OF THE INVENTION

[0015] <Embodiment> (1) Medicine container The chemical container 4 according to this embodiment is a container containing a chemical 1Y as shown in Fig. 1, and the chemical 1Y can be diffused into the surrounding space, for example, by a volatilization device 1 described later. The volatilization device 1 can be used in a variety of places, such as living spaces, automobiles, offices, toilet spaces, and closets.

[0016] The chemical 1Y is a volatile liquid chemical 1Y. There are no particular limitations on the chemical 1Y, and examples thereof include fragrances, deodorants, insect repellents, and mixtures thereof. The chemical 1Y also contains additives depending on the purpose. Examples of additives include fragrances, deodorant components, insect repellent components, and coloring agents.

[0017] As shown in FIG. 2, the drug container 4 includes a container body 41, a lid 44, and a plate member 45.

[0018] (1.1) Container body The container body 41 is a part that constitutes the main body of the drug container 4. The container body 41 is made of a hard resin. There are no particular limitations on the resin, and examples thereof include polyethylene terephthalate, polyethylene, polypropylene, polystyrene, polycarbonate, acrylic, polyvinyl chloride, and laminates thereof. In this embodiment, the container body 41 is made of a laminate of polyethylene terephthalate and polyethylene.

[0019] The container body 41 according to this embodiment is made of a transparent resin so that the remaining amount of the drug 1Y can be visually confirmed. The term "transparent" as used herein means that the degree of transparency is sufficient to allow the remaining amount of the drug 1Y to be visually confirmed, and includes so-called translucency. Note that in the present invention, the container body 41 may be made of an opaque material.

[0020] The container body 41 includes a storage section 42 and a flange section 43. The storage section 42 is a portion of the container body 41 where the drug 1Y is stored. The storage section 42 is formed in a container shape with an opening on one side. As shown in FIG. 3 , the storage section 42 includes a drug storage section 421 and a plate storage section 422.

[0021] The agent containing portion 421 is a portion that mainly contains the agent 1Y. As shown in FIG. 3 , the agent containing portion 421 includes a bottom wall 4211 that is generally rectangular in plan view, and a first side wall 4212 that rises from the outer periphery of the bottom wall 4211. The plate material containing portion 422 is a portion that contains the plate member 45, and is formed between the agent containing portion 421 and the flange portion 43. The plate material containing portion 422 includes a support portion 4221 that is connected to the first side wall 4212 of the agent containing portion 421, and a second side wall 4222 that rises from the outer periphery of the support portion 4221. The opening surface of the containing portion 42 is formed by the end of the second side wall 4222 on the flange portion 43 side.

[0022] The dimension (internal dimension) of the agent containing section 421 in a direction perpendicular to the bottom wall 4211 is not particularly limited, but is set to, for example, 5 mm or more and 20 mm or less. The height dimension (internal dimension) of the plate material containing section 422 in a direction perpendicular to the bottom wall 4211 is set appropriately depending on the thickness dimension of the plate member 45, but is set to, for example, 1 mm or more and 5 mm or less.

[0023] The flange portion 43 is a portion to which the lid body 44 is joined. The flange portion 43 is provided along the entire outer periphery of the opening surface of the storage portion 42. The surface of the flange portion 43 to which the lid body 44 is joined (sometimes referred to as the "joining surface 431") is flat. The entire joining surface 43 is located on the same plane.

[0024] (1.2) Lid Lid 44 is joined to flange 43 so as to close the opening of container body 41. Lid 44 can be joined to flange 43 by, for example, welding or adhesive, but here, it is joined by welding. Lid 44 is flexible. Lid 44 includes rupture membrane 441 and volatilization membrane 442. Lid 44 is arranged in this order from the inside to the outside of drug container 4, rupture membrane 441 and volatilization membrane 442. The allowable dimension for the gap between rupture membrane 441 and volatilization membrane 442 (i.e., the dimension when the membranes are close to each other) is 1 mm or less.

[0025] The rupture film 441 is configured to rupture with a smaller extension than the volatilization film 442 when an external force (pressure) is applied to the volatilization film 442 from the outside in the thickness direction of the lid 44. The rupture film 441 is made of a liquid-impermeable material. The rupture film 441 may be, for example, a thin film formed by laminating a polyethylene layer, an aluminum layer, and a polyethylene terephthalate layer.

[0026] A specific example of the rupture film 441 is a thin film in which a first polyethylene layer, an aluminum layer, a second polyethylene layer, and a polyethylene terephthalate layer are laminated in this order from the inside to the outside. In this case, for example, the thickness of the first polyethylene layer is set to 5 μm to 30 μm, the thickness of the aluminum layer is set to 5 μm to 25 μm, the thickness of the second polyethylene layer is set to 5 μm to 25 μm, and the thickness of the polyethylene terephthalate layer is set to 5 μm to 25 μm.

[0027] The volatilization membrane 442 volatilizes the drug 1Y while retaining the drug 1Y that has passed through holes (rupture holes) formed in the rupture membrane 441. The volatilization membrane 442 is disposed on the outer surface of the rupture membrane 441 (the surface of the rupture membrane 441 opposite the container body 41 in the thickness direction). The volatilization membrane 442 is less likely to rupture than the volatilization membrane 442 when an external force is applied to the volatilization membrane 442 from the outside in the thickness direction of the lid 44. Examples of the volatilization membrane 442 include porous films such as Teslin (trademark) and Daramic (trademark).

[0028] 3, in the lid 44 according to this embodiment, the rupture film 441 is joined to a portion of the inner edge of the joining surface 431 of the flange portion 43, and the volatilization film 442 is joined to a portion of the outer edge side of the joining portion of the rupture film 441. This allows the rupture film 441 to be joined to the flange portion 43 first, and then the volatilization film 442 to be joined, making it less likely that poor joining will occur. When joining by welding, it is only necessary to provide a welding layer on only one side of the thickness direction of the rupture film 441, which improves manufacturability.

[0029] Here, Fig. 4 shows the joint portion of the rupture film 441 and the volatilization film 442 with respect to the flange portion 43. In Fig. 4, symbol M1 indicates the joint portion of the rupture film 441, and symbol M2 indicates the joint portion of the volatilization film 442. As shown in Fig. 4, a predetermined gap S1 is interposed between the joint portion of the rupture film 441 and the joint portion of the volatilization film 442. Because the predetermined gap S1 is interposed around the entire periphery between the joint portion of the rupture film 441 and the joint portion of the volatilization film 442, even if the rupture film 441 is not joined to the flange portion 43 with precision, the volatilization film 442 can be joined appropriately.

[0030] The predetermined gap S1 is preferably set to 1 mm or more and 3 mm or less, and here, it is designed to be a gap of 1.5 mm around the entire circumference. In this case, for example, if the rupture film 441 is shifted 1.5 mm from the designed position in one direction in the width direction, the gap between the joint portion M1 of the rupture film 441 and the joint portion M2 of the volatilization film 442 in one direction in the width direction will be 0 mm, and the gap between M1 and M2 on the other side will be 3 mm, but the position and joint area of ​​the joint portion M2 of the volatilization film 442 will not change as designed.

[0031] In this embodiment, the following design is used as an example: the dimension L2 from the inner edge of the bonding surface 431 to the inner edge of the rupture film 441 is 1 mm, the width H1 of the bonding portion M1 of the rupture film 441 is 4 mm, and the width H2 of the bonding portion of the volatilization film 442 is 3.5 mm. However, these dimensions are merely an example.

[0032] (1.3) Plate members Plate member 45 is a member for partially preventing extension of lid body 44 when an external force is applied to lid body 44. Plate member 45 makes it easier for rupture film 441 to rupture when an external force is applied. As shown in Fig. 2, plate member 45 is formed in a substantially rectangular plate shape. There are no particular restrictions on the material of plate member 45, and examples include polypropylene, polyethylene terephthalate, polyethylene, polystyrene, polycarbonate, acrylic, polyvinyl chloride, and laminates thereof.

[0033] A plurality of (here, two) through holes 451 are formed in the plate member 45. The plurality of through holes 451 are formed at both longitudinal end portions of the plate member 45. The through holes 451 are formed at positions corresponding to portions to which an external force is to be applied.

[0034] (1.4) Manufacturing method The drug container 4 according to this embodiment is manufactured, for example, by a manufacturing method as shown in Fig. 5. First, the container body 41 is molded, and after molding the container body 41, a plate member 45 is placed in the plate material housing portion 422 of the container body 41. Thereafter, the drug 1Y is filled into the drug housing portion 421 (Figs. 5(A) to (C)).

[0035] Next, sheet material 441A forming rupture film 441 is bonded to a portion extending from the inner periphery of flange portion 43 of container body 41 to a certain extent. After this, the bonded sheet material 441A is cut so as to cut the periphery of the bonded portion, thereby forming rupture film 441 (FIGS. 5(D) to (E)).

[0036] Next, sheet material 442A forming volatilization film 442 is placed on the outside of rupture film 441, and sheet material 442A is joined to the part of flange portion 43 that is on the outer edge side of the joining part of rupture film 441. Thereafter, sheet material 442A forming volatilization film 442 is cut, and volatilization film 442 is removed, and drug container 4 is completed.

[0037] <Usage example> As an example of how to use the chemical container 4 configured in this way, an example in which it is used in the volatilization device 1 will be described below.

[0038] (2) Overall structure The volatilization device 1 according to this embodiment is a device that volatilizes a chemical 1Y from a chemical container 4 housed therein and diffuses the chemical 1Y in a space in which the volatilization device 1 is disposed. As shown in Fig. 6, the volatilization device 1 includes a housing 2 that houses the chemical container 4 and a movable body 3 that moves relative to the housing 2. When the movable body 3 moves relative to the housing 2, the rupture membrane 441 of the chemical container 4 ruptures, and the chemical 1Y in the chemical container 4 begins to flow to the volatilization membrane 442.

[0039] The volatilization device 1 according to this embodiment is used by placing it on a placement surface 1G, as shown in Figure 7. However, in the present invention, there are no particular limitations on the installation manner of the volatilization device 1, and it may be installed, for example, by hanging it from a ceiling or the like, hooking it onto a handle or the like, or by attaching it to a glass surface or a mirrored surface with a suction cup or the like. Here, as an example of an installation manner, an example in which it is placed on a horizontal placement surface 1G will be described.

[0040] (3) Housing The housing 2 forms the outer shell of the volatilization device 1. The housing 2 includes a main body 21 and legs 22. The front and back surfaces of the main body 21 are inclined relative to the horizontal plane. Here, when the main body 21 is viewed in a direction perpendicular to the front surface of the main body 21 (this is referred to as the "front view" of the main body 21), the direction parallel to the left-right direction is defined as the "width direction," and the direction perpendicular to the width direction is defined as the "length direction." Furthermore, the direction perpendicular to the width direction and the length direction (i.e., the direction perpendicular to the front surface of the main body 21) is defined as the "thickness direction." In the following description, the length direction of the main body 21 will be simply referred to as the "length direction." The width direction of the housing 2 will be simply referred to as the "width direction." The thickness direction of the housing 2 will be simply referred to as the "thickness direction."

[0041] The main body 21 is formed in a flat box shape, and is formed in a generally rectangular shape when viewed from the front. "Flat" here means a shape in which the thickness dimension is shorter than the width and length dimensions. The length direction is inclined with respect to the lower surfaces of the legs 22 (sometimes referred to as the bottom of the housing 2) that rest on the placement surface 1G. The angle between the length direction and the lower surfaces of the legs 22 (when viewed from the side) is, for example, 45° or more and less than 90°.

[0042] 8, the housing 2 includes a frame 23 that forms legs 22 and the rear and side surfaces of the main body 21, and a cover 29 that forms the front of the main body 21. The housing 2 is formed into a hollow shape by assembling the frame 23 and the cover 29. There are no particular restrictions on the material of the housing 2, and examples include synthetic resin, metal, pulp, carbon, and ceramic.

[0043] (3.1) Frame The frame 23 is a part that forms the framework of the housing 2. The frame 23 is formed in a container shape with an opening on the front surface in the thickness direction. The frame 23 includes a back plate portion 24 and side plate portions 28.

[0044] The back plate portion 24 constitutes the back surface of the main body portion 21. The back plate portion 24 is inclined with respect to the horizontal plane, and the main surface of the back plate portion 24 faces in the thickness direction. As shown in FIG. 9 , the back plate portion 24 includes a plurality of ventilation holes 25 and an attachment portion 26.

[0045] Vent 25 is an opening through which volatilized drug 1Y from drug container 4 passes. Vent 25 penetrates back plate 24. Multiple vents 25 are formed in parts other than the central part of back plate 24 (i.e., mounting part 26). The shape of each vent 25 is formed into a rectangular, triangular, trapezoidal, or other shape depending on the location, but is not limited thereto and can also be formed into, for example, a circular, elliptical, pentagonal, hexagonal, mesh, or other shape.

[0046] The mounting portion 26 is a portion for mounting the movable body 3. The mounting portion 26 is configured as a portion that forms a range in the center in the width direction and the center in the length direction of the back plate portion 24. As shown in FIG. 9(A), the mounting portion 26 includes an operation portion opening 261, a pair of holding portions 262, a plurality of guide portions 263, and a vibration portion 27.

[0047] The operation unit opening 261 is an opening through which the operation unit 31 of the movable body 3 passes. The operation unit opening 261 is formed in a substantially rectangular shape. The operation unit 31, which will be described later, passes through the operation unit opening 261 from the inside to the outside of the housing 2 and is exposed from the housing 2. Within the operation unit opening 261, the operation unit 31 can move along the thickness direction.

[0048] The holding portion 262 is a portion that holds a part of the elastic portion 33 of the movable body 3 on the mounting portion 26. As described above, the movable body 3 can move along the thickness direction, but the holding portion 262 holds the elastic portion 33, so that the range of movement of the movable body 3 is restricted to a certain range. The operation of the elastic portion 33 will be explained later in "(3.3) Elastic portion."

[0049] As shown in Figure 9(A), the pair of holding portions 262 are spaced apart in the lengthwise direction. In the volatilization device 1 according to this embodiment, the pair of holding portions 262 are formed at positions corresponding to both ends in the longitudinal direction (length direction) of the movable body 3. However, the pair of holding portions 262 may also be spaced apart in the widthwise direction, in which case they should be formed at positions corresponding to both ends in the short side direction of the movable body 3.

[0050] In this embodiment, each holding portion 262 is configured by a hook-shaped claw that holds a part of the elastic portion 33 so as not to move in the thickness direction. However, the holding portion 262 is not limited to a claw, and may be configured by, for example, welding, pinning, screwing, or a bearing with a C-shaped cross section.

[0051] The mounting portion 26 has an operating portion opening 261, a pair of holding portions 262, as well as multiple guide portions 263 and a vibration portion 27, but the guide portions 263 and the vibration portion 27 will be explained after explaining the movable body 3.

[0052] The side plate portion 28 is a portion that protrudes in the thickness direction from the outer periphery of the back plate portion 24. The protruding tip of the side plate portion 28 forms the opening surface of the frame 23. The side plate portion 28 forms the side peripheral surface of the housing 2. In the volatilization device 1 according to this embodiment, the side plate portion 28 does not have an air vent 25 formed therein, but an air vent 25 may be formed therein.

[0053] (3.2) Cover Cover 29 is a member that closes the opening on the front side of frame 23. As shown in FIG. 8 , cover 29 closes the opening side of frame 23 with movable body 3 and drug container 4 housed within frame 23. Cover 29 has a remaining amount display window 291 that allows the remaining amount of drug 1Y in drug container 4 to be visually confirmed. Remaining amount display window 291 is composed of a through-hole 294 that is formed in the main body of cover 29 and extends in the length direction, and a transparent plate 293 that covers through-hole 294. Through-hole 294 is formed at a position corresponding to drug container 4 housed inside housing 2.

[0054] (4) Movable body The movable body 3 is a member that is movably provided with respect to the housing 2. As shown in FIG. 11, the movable body 3 includes an operating unit 31, a movable unit 32, and a pair of elastic units 33. As shown in FIG. 10, the operating unit 31 can move along the thickness direction. The operating unit 31 is configured to be movable between an initial position (a position where the movable unit 32 abuts against the back plate unit 24; see FIG. 10(A)) and a position where the movable unit 32 opens the drug container 4 (see FIG. 10(B)). In this embodiment, within the movement range of the operating unit 31, the initial position is defined as a "first position," and the position where the movable unit 32 opens the drug container 4 is defined as a "second position."

[0055] In this embodiment, the operating portion 31, the movable portion 32, and the elastic portion 33 are integrally molded. The material of the movable body 3 is not particularly limited, and examples thereof include synthetic resin, metal, pulp, and carbon.

[0056] (4.1) Operation section The operation unit 31 is a part that is operated by the user. As described above, the operation unit 31 is exposed from the housing 2 through the operation unit opening 261 in the back plate portion 24 of the housing 2. The operation unit 31 according to this embodiment is movable from a first position to a second position along the thickness direction. When the user presses the operation unit 31 in the first position toward the housing 2, the movable body 3 can be moved.

[0057] 11(B), the operating unit 31 protrudes from the movable unit 32 toward the rear side in the thickness direction. The operating unit 31 is formed in a rectangular parallelepiped shape, but may have various shapes, such as a cylindrical shape, a columnar shape, a hemispherical shape, a truncated cone shape, or a truncated pyramid shape.

[0058] (4.2) Movable parts The movable part 32 is a part that constitutes the main body of the movable body 3. The movable part 32 moves integrally with the operating part 31. The movable part 32 is formed in an oval shape having a long axis (in other words, a "longitudinal axis") parallel to the lengthwise direction. As shown in FIG. 11(A), the movable part 32 includes a plurality of (here, two) protruding parts 321 formed at intervals along the longitudinal axis, and a pair of guided parts 322 spaced apart along a short axis perpendicular to the longitudinal axis.

[0059] As shown in FIG. 10(A), when the operating unit 31 is in the first position, each of the plungers 321 is separated from the drug container 4. On the other hand, when the operating unit 31 is moved to the second position, each of the plungers 321 opens a hole in the drug container 4 to open the drug container 4, as shown in FIG. 10(B). As shown in FIG. 11(A), the plurality of plungers 321 are formed at both ends of the movable unit 32 in the direction along the longitudinal axis. Each plunger 321 protrudes from the surface of the movable unit 32 on the first position side in the movement direction. Examples of the shape of each plunger 321 include a spindle shape (cone shape, pyramid shape), a needle shape, a rod shape, etc., but a cone shape is preferable.

[0060] The term "pyramidal" as used herein means a three-dimensional shape with a pointed tip. The tip of the protruding portion does not necessarily have to be sharp, but may be a hemispherical tip with a small radius of curvature.

[0061] The multiple protrusions 321 are spaced apart in the longitudinal direction (i.e., lengthwise direction) of the movable part 32. As a result, as shown in FIG. 10, holes can be drilled above and below the center of the drug container 4, allowing holes to be drilled in both the gas phase and the liquid phase within the drug container 4. As a result, the upper holes of the multiple holes can be used as air intake holes, and the lower holes can be used as drug passage holes. Therefore, the drug container 4 can easily discharge the drug 1Y and maintain a stable volatilization rate of the drug 1Y. It is preferable that the lower protrusion 321 of the protrusions 321 aligned in the longitudinal direction of the movable part 32 be drilled as close as possible to the opening edge of the container body 41. Note that "upper" refers to the upper side when the volatilization device 1 is placed on the mounting surface 1G. "lower" refers to the lower side when the volatilization device 1 is placed on the mounting surface 1G.

[0062] 11(A), the guided portion 322 is a portion that fits into the guide portion 263 and is guided by the guide portion 263. The guided portion 322 according to this embodiment is configured with a pair of concave grooves 3221 that are spaced apart in the short axis direction (width direction). Each groove 3221 extends along the movement direction (thickness direction) of the movable portion 32. The opening surfaces of the pair of grooves 3221 face in opposite directions.

[0063] The movable part 32 has an opening 323 formed therein for passing the vibration part 27 described later. The opening 323 is formed above the operation part 31 in the longitudinal axis direction. The opening 323 will be described later in "(5) Vibrator, contact part".

[0064] (4.3) Elastic part The pair of elastic portions 33 are portions that connect the movable portion 32 and the housing 2. As shown in FIG. 11(A), the elastic portion 33 is composed of an arc portion 331 and a pair of arm portions 332 extending from both ends of the arc portion 331, and is formed in a substantially U-shape. As shown in FIG. 9(B), the arc portion 331 is a portion that is held by the holding portion 262 of the housing 2. As shown in FIG. 11(B), the arm portion 332 connects the arc portion 331 and the movable portion 32. The arc portion 331 is disposed with a gap between it and an edge of the movable portion 32 in the longitudinal direction. The pair of arm portions 332 are disposed with a gap between them and edges of the movable portion 32 in the lateral direction. The end of the arm portion 332 on the opposite side of the arc portion 331 in the longitudinal direction is connected to the center of the movable portion 32 in the longitudinal direction.

[0065] The connection portions of the pair of elastic portions 33 with respect to the movable portion 32 are spaced apart from each other in the longitudinal axis direction. Here, the guided portion 322 is disposed between the connection portions. The dimension D1 between the connection portions is preferably 2 mm or more and 30 mm or less, and more preferably 5 mm or more and 10 mm or less.

[0066] When the movable body 3 is attached to the attachment portion 26 of the frame 23, the operation portion 31 is located in the first position, as shown in FIG. 12(A). When an external force is applied to the operation portion 31 (i.e., when it is pushed into the housing 2) while the operation portion 31 is located in the first position, the elastic portion 33 is elastically deformed, as shown in FIG. 12(B). The movable portion 32 moves in conjunction with the operation portion 31 moving from the first position to the second position (FIG. 12(A) → FIG. 12(B)). In this state, when the external force applied to the operation portion 31 is removed, the elastic portion 33 returns to its original state. The movable portion 32 returns in conjunction with the operation portion 31 moving from the second position to the first position (FIG. 12(B) → FIG. 12(A)).

[0067] (5) Guide section As shown in FIG. 9(B), when the movable body 3 is attached to the frame 23, the guided portion 322 of the movable body 3 fits into the guide 265 of the guide portion 263. The guide portion 263 is formed on the frame 23 and fits into a portion (the guided portion 322) of the movable portion 32 to guide the movement of the movable portion 32. This allows the movable portion 32 to move in parallel when the operating unit 31 moves between the first position and the second position. As shown in FIG. 9(A), the multiple guide portions 263 are arranged spaced apart in the width direction and are formed on both sides of the operating unit opening 261. As shown in FIG. 13, each guide portion 263 includes an upright wall 264, a guide 265, and a stopper 266.

[0068] The upright wall 264 rises in the thickness direction from the front surface of the back plate portion 24. The upright wall 264 is formed along both sides of the periphery of the operation portion opening 261 in the width direction.

[0069] The guide 265 fits into a guided portion 322 formed on the movable portion 32, and guides the movement of the movable portion 32. The guide 265 is composed of a protrusion 2651 extending along the movement direction of the movable portion 32. Here, the guide 265 is composed of one protrusion 2651, but it may be composed of multiple protrusions 2651.

[0070] The guide 265 fits into a groove 3221 (guide portion 322) formed in the movable portion 32. In this embodiment, both the ridge 2651 (guide 265) and the groove 3221 (guide portion 322) extend along the movement direction of the movable portion 32, and therefore the movable portion 32 can achieve stable translation when moving along the direction from the first direction to the second direction.

[0071] However, in this embodiment, the guide 265 is formed by the ridge 2651 and the guided portion 322 is formed by the groove 3221, but for example, the guide 265 may be formed by a plurality of cylindrical protrusions spaced apart in the direction from the first direction to the second direction. Also, the guide 265 may be formed by a single protrusion. Furthermore, the guide 265 may be formed by the groove 3221 and the guided portion 322 may be formed by the ridge 2651 or one or more protrusions.

[0072] When the operating unit 31 moves to the second position, the stopper 266 prevents the movable unit 32 from moving further. As shown in FIG. 13(A), the stopper 266 is configured with a claw formed at the protruding tip of the upright wall 264. When the movable unit 32 moves to the second position, the stopper 266 comes into contact with a part of the movable unit 32 (a restriction surface 3222) as shown in FIG. 13(B). This restricts the movable unit 32 from moving further even if the operating unit 31 is pushed in.

[0073] (6) Vibrator, contact part In this embodiment, as described above, when the operation unit 31 moves to the second position, the stopper 266 prevents the operation unit 31 from moving. In addition, a sound is emitted to notify the user that the movable body 3 has moved to the second position. As shown in FIG. 10 , a contact portion 324 is formed on the movable body 3, and a vibrator 272 is formed on the housing 2. The vibrator 272 is configured so that, when the operation unit 31 moves to the second position, the contact portion 324 causes the vibrator 272 to vibrate, thereby generating a sound.

[0074] As shown in Fig. 9(A), a vibration unit 27 is provided on the frame 23 of the housing 2. The vibration unit 27 is formed between an operation unit opening 261 and an upper holding unit 262. As shown in Fig. 14, the vibration unit 27 includes a base unit 271 and a vibrator 272 provided on the base unit 271.

[0075] Base portion 271 is a portion that serves as a base for vibrator 272. Base portion 271 protrudes from the inner surface of housing 2 (the surface on the front side of frame 23). Base portion 271 passes through opening 323 in movable portion 32 when operation unit 31 is located at the first position (FIG. 9(B)).

[0076] The vibrator 272 is a part that vibrates when it bounces off the contact portion 324 after coming into contact with it. The vibrator 272 is formed at the tip of the base portion 271. The vibrator 272 has a fixed end connected to the base portion 271 and a free end, and is formed in a cantilever shape. The vibrator 272 is formed so that the dimension L1 in the length direction between the fixed end and the free end is longer than the dimension L2 in the width direction of the fixed end. The vibrator 272 is also formed so that its width becomes narrower toward the free end. This makes it easier to vibrate the vibrator 272.

[0077] 11, contact portion 324 is formed on the periphery of opening 323 in movable body 3. Contact portion 324 is configured as a protrusion formed on the periphery of opening 323, but may be configured as part of the periphery of the opening as long as the periphery of the opening can be designed to contact vibrator 272. Contact portion 324 can repel vibrator 272 when operation unit 31 comes into contact with the free end of vibrator 272 slightly closer to the first position than the second position and movable body 3 reaches the second position.

[0078] The vibrator 272 vibrates when struck by the contact portion 324, thereby producing a snapping sound such as a "snap." Note that the vibrator 272 does not necessarily have to produce a sound, and may vibrate to produce a clicking sensation that indicates that the movable body 3 has moved to the second position.

[0079] 15, when operating unit 31 is pressed while it is in the first position, movable portion 32 moves toward the second position, and contact portion 324 comes into contact with vibrator 272 just before operating unit 31 reaches the second position (FIG. 15(A)→(B)). When operating unit 31 is pressed further from this position, contact portion 324 repels vibrator 272, generating a sound, and operating unit 31 reaches the second position (FIG. 15(C)→(D)).

[0080] After that, when the external force applied to the operation unit 31 is removed, the elastic portion 33 returns to its original state, and the movable portion 32 moves to the first position. At this time, the contact portion 324 comes into contact with the vibrator 272 again, and then the contact portion 324 repels the vibrator 272, generating sound again (FIG. 15(E)→(F)), and the operation unit 31 returns to the first position (FIG. 15(G)).

[0081] In this way, since the volatilization device 1 according to this embodiment includes the vibrator 272 and the contact part 324, it is possible to notify the user that the operation part 31 has moved to the position where the medicine container 4 has been opened. As a result, the medicine container 4 can be opened reliably.

[0082] Furthermore, vibrator 272 is positioned above operation unit 31. Here, vibrator 272 is disposed in a position close to lid 44 of drug container 4. After rupture membrane 441, which will be described later, ruptures, the lower part of lid 44 bulges due to the drug's own weight. If vibrator 272 is located below operation unit 31, there is a possibility that vibrator 272 will come into contact with lid 44. By positioning vibrator 272 above operation unit 31, it is possible to prevent vibrator 272 from coming into contact with lid 44.

[0083] The volatilization device 1 configured as described above operates with respect to the drug container 4 as follows. As shown in FIG. 16, when the operating part 31 moves from the first position to the second position, the plunger part 321 pushes the volatilization membrane 442. Then, the plunger part 321 pushes the rupture membrane 441. At this time, the volatilization membrane 442 and the rupture membrane 441 stretch, but the rupture membrane 441 ruptures first, creating a hole in the rupture membrane 441 (FIG. 16(A) → (B)). After this, when the external force on the operating part 31 is removed, the elastic part 33 returns the operating part 31 from the second position to the first position, and the movable part 32 and the plunger part 321 move away from the volatilization membrane 442.

[0084] Then, the chemical 1Y in the chemical container 4 is released to the outside through the lower hole. The chemical 1Y penetrates the volatilization film 442 and volatilizes. When the chemical 1Y is released to the outside, the pressure inside the container is reduced, and air is taken in through the upper hole. Therefore, the chemical container 4 can maintain a stable volatilization amount of the chemical 1Y.

[0085] (7) Effects As described above, in drug container 4 according to the present embodiment, volatilization film 442 is joined to the surface of flange portion 43 that is closer to the outer edge than joining portion M1 of rupture film 441, and therefore both rupture film 441 and volatilization film 442 can be joined to flange portion 43. As a result, appropriate joining strength of volatilization film 441 and rupture film 442 to flange portion 43 can be obtained. Moreover, a process such as providing a welding layer on both sides of rupture portion 441 in the thickness direction is no longer necessary, improving manufacturability.

[0086] Furthermore, since a gap is provided between the joining portion M1 of the rupture film 441 and the joining portion M2 of the volatilization film 442, the joining area of ​​the volatilization film 442 can be secured and the volatilization film 442 can be joined at the designed position even if the joining position of the rupture film 441 is shifted relative to the flange portion 43. By setting the gap to 1 mm or more and 3 mm or less, the flange portion 43 can be prevented from becoming large.

[0087] Furthermore, since the joint portion M1 of the rupture film 441 of the flange portion 43 and the joint portion M2 of the volatilization film 442 are located on the same plane, the gap between the rupture film 441 and the volatilization film 442 can be minimized. Therefore, compared to when a gap is interposed between the rupture film 441 and the volatilization film 442, the volatilization film 442 is less likely to rupture before the rupture film 441 or to stretch too much. Therefore, it is possible to prevent holes from being formed in the volatilization film 442 before the rupture film 441 ruptures.

[0088] Furthermore, the volatilization device 1 comprises a drug container 4, a housing 2, and a movable body 3 having an operating unit 31, and the movable body 3 has a plunge portion 321 that ruptures the rupture membrane 441 via the volatilization membrane 442 when the operating unit 31 moves to the second position, so that it is possible to provide a volatilization device 1 that is suitable for use with the drug container 4 of this embodiment.

[0089] <Modification> The above embodiment is merely one of various embodiments of the present invention. The embodiment can be modified in various ways depending on the design, etc., as long as the object of the present invention can be achieved. Modifications of the embodiment are listed below. The modifications described below can be applied in appropriate combinations.

[0090] In the drug container 4 according to the above embodiment, the rupture membrane 441 is joined to the flange portion 43, and then the volatilization membrane 442 is joined to the flange portion 43, but the rupture membrane 441 and the volatilization membrane 442 may be joined to the flange portion 43 simultaneously.

[0091] In the volatilization device 1 according to the above embodiment, the movable body 3 is configured as a separate member from the housing 2, but the housing 2 and the movable body 3 may be formed integrally.

[0092] The operation unit 31 according to the above embodiment is configured to be movable along the thickness direction of the housing 2. However, in the present invention, the movement direction of the operation unit 31 is not limited to the thickness direction of the housing 2, and the operation unit 31 may be configured to be movable along, for example, the length direction or the up-down direction of the housing 2. In this case, the operation unit 31 may protrude from, for example, the side peripheral surface of the housing 2. In conjunction with the movement of the operation unit 31, the movable unit 32 may move in a direction intersecting the pushing direction. Furthermore, the operation unit 31 may be operated not only by pushing, but also by sliding, rotating, pulling, etc.

[0093] In the above embodiment, the movable portion 32 is formed in an oval shape, but it may also be formed in, for example, a rectangular, strip-like, square, or disk-like shape.

[0094] In the above embodiment, the guide 265 and the guided portion 322 are composed of a protrusion 2651 or projection and a concave groove 3221, but in the present invention, they may be composed of, for example, a rod and a hole, and there are no particular restrictions on the shape.

[0095] In the above embodiment, the stopper 266 is provided to restrict the movement of the movable part 32 when the operating part 31 moves to the second position, but the stopper 266 may be omitted. In other words, the operating part 31 may be configured to be able to move further beyond the first position after moving from the first position to the second position.

[0096] In the above embodiment, the vibrator 272 is provided only above the operation unit 31, but in the present invention, it may be provided on both sides of the operation unit 31 in the vertical direction, or may be provided only below the operation unit 31.

[0097] In the above embodiment, the vibrator 272 is provided in the housing 2 and the contact portion 324 is provided in the movable body 3, but the vibrator 272 may be provided in the movable body 3 and the contact portion 324 may be provided in the housing 2. In this case, too, it is possible to similarly notify the user that the movable body 3 has moved to the position where the medicine container 4 was opened.

[0098] In the above embodiment, the length direction of the main body 21 is inclined with respect to the horizontal plane, but in the present invention, the length direction of the main body 21 may be parallel to the vertical direction. Also, while the main body 21 is formed so that the length dimension is longer than the width dimension, in the present invention, the length dimension and the width dimension may be the same, or the width dimension may be longer than the length dimension. Note that in the above embodiment, the embodiment is described based on the "thickness direction," "length direction," and "width direction" of the housing 2, but the "thickness direction," "length direction," and "width direction" of the housing 2 can also be rephrased as the "first direction," "second direction," and "third direction," respectively.

[0099] Furthermore, the "rupture film 441" and the "volatilization film 442" can also be referred to as the "first film" and the "second film", respectively.

[0100] In this specification, expressions accompanied by "approximately", such as "approximately parallel" or "approximately perpendicular", may be used. For example, "approximately parallel" means that the state is substantially "parallel", and includes not only a strictly "parallel" state but also an error of a few degrees. The same applies to other expressions accompanied by "approximately".

[0101] Furthermore, in this specification, expressions such as "end" and "edge" are used that are distinguished by the presence or absence of "... part." For example, "edge" means the end of an object, while "edge" means a region having a certain range that includes the "edge." Any point within a certain range that includes the edge is considered to be an "end." The same applies to other expressions that include "... part." [Explanation of symbols]
