Japanese Unexamined Patent Publication No. 2013-123992

However, it is not easy to open the inner bag by pressing the bag body with the pressing member, and the inner bag cannot be opened unless the pressing member is pushed in with a relatively strong force. Therefore, there has been a demand for a drug volatilizer that can easily open the inner bag when the pressing member is pushed in. An object of the present invention is to solve the above-mentioned problems, and to provide a drug volatilizer capable of easily opening the inner bag of a bag body.

The drug volatilizer according to the present invention communicates with the outside through an inner bag that contains a liquid drug and can be opened by the action of an external force, and a bag that contains the inner bag and has a gas-permeable outer bag. A container having at least one vent and having a first internal space for accommodating the bag body, and the container has a bottom wall portion and a side wall portion extending from a peripheral edge of the bottom wall portion. An intermediate portion between a container body having a through hole formed in the bottom wall portion, a cover member formed in a dome shape covering the upper portion of the container body, and the container body and the cover member. The bag body is housed in the first internal space formed between the container body and the intermediate member, and the container body is arranged at a position corresponding to the through hole. A pressing member having a pressing surface capable of pressing the bag body arranged in the first internal space and the pressing member are connected to the edge of the through hole so as to be swingable in the axial direction of the through hole. The intermediate member is a base portion, a first support portion projecting from the base portion toward the pressing member side of the container body, and a second supporting portion projecting from the base portion toward the cover member side so as to be in contact with the cover member. A support portion is provided, and the bag body is arranged so as to be sandwiched between the first support portion and the pressing member. In the first support portion, the pressing member swings toward the first support portion. When moved, it has a support surface that faces substantially parallel to the pressing surface of the pressing member.

According to this configuration, when the pressing member is pressed and rocked, the pressing surface of the pressing member and the support surface of the first support portion are arranged substantially in parallel, so that the bag body is formed between these parallel surfaces. Can be pressed. Therefore, even force can be applied to the bag body in this plane direction. As a result, the inner bag of the bag body can be easily opened.

Further, since the cover member is formed in a dome shape, it is easy to hold by hand. Therefore, it is possible to facilitate the operation of pressing the pressing member from the opposite side of the cover member while holding the cover member by hand.

Further, since the intermediate member is provided with a first support portion that can come into contact with the cover member, when the pressing member is pressed, the force is transmitted to the intermediate member via the bag body, whereby the first support member is provided. The support portion can be brought into contact with the cover member. Therefore, since the force for pressing the pressing member is received by the cover member, it is possible to prevent the pressing force from being dispersed, and the force can be reliably transmitted to the bag body. In the present invention, the inner bag of the bag body can be easily opened by the above three configurations.

In the drug volatilizer, the first support portion and the second support portion can be arranged at positions facing each other with the base portion interposed therebetween.

With this configuration, the force for pressing the pressing member can be directly transmitted from the first support portion to the second support portion, and the pressing force can be more reliably prevented from being dispersed.

In the chemical volatilizer, a second internal space can be formed between the cover member and the base portion of the intermediate member, and the base portion partitions the first internal space and the second internal space. Can be formed in a plate shape.

According to this configuration, since the first internal space and the second internal space are separated by the base, for example, even if the drug in the bag body leaks, it can be retained in the first internal space and the second internal space. It is possible to prevent the flow to the space side.

In the drug volatilizer, the cover member can be formed in an elliptical shape having a major axis of 10 cm or less and a minor axis of 8 cm or less in a plan view.

If the cover member has such a size, the cover member can be easily held by hand. Therefore, when the pressing member is pressed, the cover member can be easily supported by hand, and the opening operation of the bag body can be easily performed.

According to the drug volatilizer according to the present invention, the inner bag of the bag body can be easily opened.

Hereinafter, an embodiment of the drug volatilizer according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the drug volatilizer viewed from above, FIG. 2 is a perspective view of the drug volatilizer viewed from below, and FIG. 3 is an exploded perspective view of the drug volatilizer. As shown in FIGS. 1 to 3, the drug volatilizer includes a bag body 1 containing a liquid drug and a container 2 containing the bag body 1. First, the bag body 1 will be described, and then the container 2 will be described. In the following, for convenience of explanation, the description will be given with reference to the directions in the drawings of each drawing. However, the present invention is not limited by the provision of this direction.

<1. Bag body>
The bag body will be described with reference to FIGS. 4 and 5. FIG. 4 is a perspective view of the bag body, and FIG. 5 is a sectional view taken along line AA of the bag body.

As shown in FIGS. 4 and 5, the bag body 1 includes an inner bag 11 containing a liquid drug and an outer bag 12 containing the inner bag 11. The inner bag 11 is formed of two first sheet materials formed in a rectangular shape in a plan view, and is formed flat by welding the peripheral edges of these first sheet materials with a heat seal or the like. .. The heat seal is formed with such strength that it peels off when the internal pressure of the inner bag 11 increases. Therefore, as will be described later, when the inner bag 11 is pressed, the internal pressure increases, the heat seal on the peripheral edge is peeled off, and the drug flows out.

Since the first sheet material is made of a gas-impermeable material, it can hold the drug without leaking unless an external force acts on it. The first sheet material is not particularly limited as long as it is a gas impermeable material, but is thermoplastic synthesis of, for example, polyester, polyamide, ethylene-vinyl acetate copolymer saponified product, modified polyvinyl alcohol, polyvinylidene chloride and the like. A multilayer laminated material containing one or more of metal foils such as resin or aluminum can be used.

The outer bag 12 is formed of two second sheet materials formed in a rectangular shape in a plan view, and is formed in a flat shape by welding the peripheral edges of these second sheet materials with a heat seal or the like. .. The heat seal is formed with a strength that does not peel off even if the internal pressure of the outer bag 12 increases. Therefore, as will be described later, even if the bag body 1 is pressed, the heat seal of the outer bag 12 is usually not peeled off.

The second sheet material is made of a gas permeable material. Therefore, the components of the drug are volatilized to the outside through the outer bag 12. The second sheet material is not particularly limited as long as it is gas permeable, but the outer bag 12 can also be made of a sheet material having at least a part of a gas permeable region. Alternatively, for example, the outer bag 12 can be made by using at least a part of a microporous sheet having a large number of micropores formed such that a drug as disclosed in Japanese Patent Application Laid-Open No. 2015-123992 is slightly exuded. It can also be configured.

The drug is a volatile drug and can contain various functional components such as an aromatic component, a deodorant component, an insect repellent component, and an antibacterial component. Moreover, such a functional component may be either oil-based or water-soluble.

<2. Container>
Next, the container 2 will be described. As shown in FIG. 3, the container 2 is arranged between the cup-shaped container body 3 constituting the lower part of the container 2, the cover member 4 for closing the upper opening of the container body 3, and the cover member 4 of the container body 3. The intermediate member 5 is provided. Hereinafter, each member will be described in detail.

<2-1. Container body>
6 is a perspective view of the container body, FIG. 7 is a side view of FIG. 6, FIG. 8 is a plan view of FIG. 6, FIG. 9 is a bottom view of FIG. 6, and FIG. 10 is a sectional view taken along line BB of FIG. .. 11 is a plan view of FIG. 6, and FIG. 12 is an operation explanatory view of FIG.

As shown in FIGS. 6 to 10, the container body 3 includes a bottom wall portion 31 having an elliptical plan view and a side wall portion 32 extending upward from the peripheral edge of the bottom wall portion 31, and is flat as a whole. It is formed in a visually elliptical shape.

A circular through hole 311 is formed in the center of the bottom wall portion 31, and a wall portion 312 is formed on the peripheral edge thereof. An annular region between the wall portion 312 and the peripheral edge of the bottom wall portion 31 constitutes a storage portion 313 for storing the liquid. The storage portion 313 is formed so as to incline downward from the peripheral edge of the bottom wall portion 31 toward the wall portion 312, thereby storing liquid between the peripheral edge of the bottom wall portion 31 and the wall portion 312. (Gray area in FIG. 11). Further, the bottom wall portion 31 is formed with a plate-shaped protruding portion 314 that protrudes upward at 90 degree intervals so as to surround the through hole 311. Each protrusion 314 is formed higher than the wall portion 312, and these four protrusions 314 support the bag body 1.

A disk-shaped pressing member 33 having a size slightly smaller than that of the through hole 311 is provided slightly above the through hole 311. An annular protrusion 331 projecting upward is formed on the peripheral edge of the pressing member 33. Then, one edge portion in the long side direction of the pressing member 33 and the wall portion 312 are connected by a band-shaped connecting member 332. As will be described later, since the container body 3 is integrally formed of a resin material or the like, the connecting member 332 can be elastically deformed. Therefore, the pressing member 33 is swingably supported by the connecting member 332, and when the pressing member 33 is pressed from the lower side of the through hole 311, the pressing member 33 is in the axial direction of the through hole 311 as shown in FIG. That is, it swings in the vertical direction. As shown in FIG. 10, in the initial state, the pressing member 33 is horizontally held above the through hole 311 at a position substantially the same height as the tip of the protruding portion 314. Therefore, when the bag body 1 is supported by the protruding portion 314, the protruding portion 331 of the pressing member 33 in the initial state comes into contact with the bag body 1.

In the present embodiment, the surface of the pressing member 33 along the annular protrusion 331 constitutes the pressing surface of the present invention, and the pressing surface (protrusion 331) presses the bag body 1 as described later.

Next, the side wall portion 32 will be described. In the side wall portion 32, rectangular ventilation holes are formed at both ends in the long side direction and both ends in the short side direction. Hereinafter, the ventilation holes at both ends in the long side direction will be referred to as a first ventilation hole 321 and the ventilation holes at both ends in the short side direction will be referred to as a second ventilation hole 322. The first vent hole 321 is formed to be longer in the circumferential direction than the second vent hole 322.

In the side wall portion 32, a plate-shaped positioning portion 323 extending upward is formed at an end portion of each of the first vent holes 321 on the side of the second vent holes 322. Each positioning portion 323 is formed so as to extend parallel to the short side direction. As shown by the broken line in FIG. 11, these four positioning portions 323 are configured to be along the short side of the bag body 1 when the bag body 1 is arranged on the container body 3. Therefore, the bag body 1 is restricted from moving in the long side direction by the positioning portion 323. When the bag body 1 is arranged on the container body 3, the bag body 1 is formed so as to have a long side in contact with the inner wall surface of the side wall portion 32 in the vicinity of the corner portion. Therefore, the side wall portion 32 restricts the movement of the bag body 1 in the short side direction. Therefore, the bag body 1 is held so as not to move in the container body 3.

Further, in the side wall portion 32, a flow path 325 inclined downward is formed between each positioning portion 323 and the second ventilation hole 322 adjacent thereto (hatching region in FIG. 11), and this flow path. The lower end of the 325 is connected to the reservoir 313. Therefore, as will be described later, the liquid received in the flow path 325 flows into the storage unit 313.

Further, in the side wall portion 32, a hook-shaped engaging portion 324 extending upward is formed at an end portion of each of the second ventilation holes 322 on the first ventilation hole 321 side. The tip of each engaging portion 324 projects upward from the side wall portion 32 and engages with the engaged portion 41 of the cover member 4 described later.

<2-2. Intermediate member>
Next, the intermediate member 5 will be described with reference to FIGS. 13 to 16. 13 is a perspective view of the intermediate member viewed from above, FIG. 14 is a perspective view of the intermediate member viewed from below, FIG. 15 is a bottom view of the intermediate member of FIG. 13, and FIG. 16 is a side view of the intermediate member.

As shown in FIGS. 13 to 16, the intermediate member 5 includes a plate-shaped base portion 51, a first support portion 52 protruding from the lower surface of the base portion 51, and a second support portion 53 protruding from the upper surface of the base portion 51. , Is equipped. The base portion 51 is formed in an elliptical shape in a plan view, and is arranged near the upper end of the side wall portion 32 of the container body 3. More specifically, the outer diameter of the base 51 is formed to be slightly smaller than the inner diameter of the upper end of the side wall portion 32 of the container body 3. Further, when the base portion 51 is arranged on the container main body 3, the positioning portion 323 of the container main body 3 supports the base portion 51. As a result, the base 51 substantially closes the upper opening of the container body 3 and is held in the vicinity of the upper opening.

Further, a notch 511 is formed at a position corresponding to the engaging portion 324 of the container body 3 at the edge portion of the base portion 51. As a result, when the base portion 51 is arranged on the container body 3, the engaging portion 324 protrudes from the notch 511.

Next, the first support portion 52 will be described. As shown in FIGS. 14 and 16, the first support portion 52 has a cylindrical first portion 521 extending downward from the base 51 and a cylindrical second portion 522 arranged inside the first portion 521. , Is equipped. Further, four first plate members 523 are arranged at 90 degree intervals between the first portion 521 and the second portion 522, and these four first plate members 523 together with the first portion 521 and the second portion 522. Are concatenated. Further, a second plate member 524 extending in the vertical direction and having a cross shape in a plan view is arranged in the second portion 522, and the second plate member 524 is connected to the inner wall surface of the second portion 522. The first plate material 523 and the second plate material 524 play a role of reinforcing the first portion 521 and the second portion 522.

As shown in FIG. 15, the lower end portions of the first portion 521 and the second portion 522 are formed so as to be inclined in a side view. More specifically, one end in the long side direction, that is, the side of the container body 3 where the connecting member 332 is provided is inclined so as to project downward. That is, the lower ends of the first portion 521 and the second portion 522 have a shape cut out by a surface that is slightly inclined from the horizontal direction. The lower ends of the first part 521 and the second part 522 are the ends of the plate material, but in the following, the surfaces along the lower ends of the first part 521 and the second part 522 will be referred to as support surfaces 520. .. The support surface 520 is inclined in a side view.

As shown in FIG. 13, the second support portion 53 is arranged at a position corresponding to the first support portion 52 with the base portion 51 interposed therebetween. It is formed in a cross shape in a plan view by combining four plate members extending upward from the base 51. The upper edge of each plate member is formed so as to be in contact with the inner surface of the cover member 4. Since the cover member 4 is formed in a dome shape as described later, the inner wall surface is formed by a curved surface. Therefore, the upper edges of the four plate members of the second support portion 53 are curved along the inner wall surface of the cover member 4.

<2-3. Cover member>
Next, the cover member 4 will be described with reference to FIGS. 17 and 18. As shown in FIGS. 17 and 18, the cover member 4 is formed in a cup shape having an elliptical shape in a plan view, and is formed in an upwardly convex dome shape. That is, it has an arcuate outer surface when viewed from the side. The lower edge portion of the cover member 4 is formed to have substantially the same size as the upper edge portion of the side wall portion 32 of the container body 3, and both are in contact with each other. Further, on the inner edge of the cover member 4, an engaged portion 41 projecting inward is formed at a position corresponding to the engaging portion 324 of the container body 3. Therefore, the hook-shaped engaging portion 324 is snap-fastened to engage the engaged portion 41, whereby the cover member 4 and the container body 3 are fixed to each other.

<3. How to assemble and use the chemical volatilizer>
First, a method of assembling the chemical volatilizer will be described with reference to FIG. First, the bag body 1 is arranged on the container body 3. At this time, the bag body 1 is positioned by the positioning unit 323, and the position is fixed as shown in FIG. Next, the upper opening of the container body 3 is closed with the intermediate member 5 so as to cover the bag body 1. At this time, the intermediate member 5 is arranged so that the engaging portion 324 protrudes from the notch 511 of the intermediate member 5. Subsequently, the cover member 4 is attached so as to cover the intermediate member 5. At this time, the cover member 4 is pushed toward the container body 3 so that the engaging portion 324 engages with the engaged portion 41. In this way, as shown in FIG. 19, the bag body 1 and the intermediate member 5 are arranged in the internal space formed by the container body 3 and the cover member 4. In the container 2, the space in which the bag body 1 is arranged corresponds to the first internal space of the present invention. In the present embodiment, the space formed by the base 51 and the container body 3 corresponds to the first internal space.

Next, a method of using the drug volatilizer will be described with reference to FIG. First, as shown in FIG. 20, the pressing member 33 is pushed in from the lower side of the container 2 while the cover member 4 is supported by hand. As a result, the pressing member 33 swings, the protrusion 331 of the pressing member 33 and the support surface 520 of the first support portion 52 become substantially parallel, and the bag body 1 arranged between them is pressed. As a result, the internal pressure of the inner bag 11 rises, and the heat seal at the edge is peeled off. As a result, the drug flows out from the inner bag 11 and accumulates in the outer bag 12. Following this, the lower surface of the container 2 is installed on the desired installation surface T.

Then, the functional component of the drug that has flowed out into the outer bag 12 volatilizes to the outside from the second sheet material. Then, this functional component volatilizes to the outside from the ventilation holes 321 and 322 of the container body 3. In this way, the effects of functional components such as aromatic components can be obtained.

<4. Features>
According to the drug volatilizer according to the present embodiment, the following effects can be obtained.
(1) When the pressing member 33 is pressed and swung, the protrusion 331 (pressing surface) of the pressing member 33 and the support surface 520 of the first support portion 52 are arranged substantially in parallel. The bag body 1 can be pressed between the surfaces. Therefore, even force can be applied to the bag body in this plane direction. As a result, the inner bag of the bag body 1 can be easily broken.

Further, since the cover member 4 is formed in a dome shape, it is easy to hold by hand. Therefore, it is possible to facilitate the operation of pressing the pressing member 33 from the opposite side of the cover member 4 while holding the cover member 4 by hand.

Further, since the intermediate member 5 is provided with the second support portion 53 that can come into contact with the cover member 4, when the pressing member 33 is pressed, the force is transmitted to the intermediate member 5 via the bag body 1. As a result, the second support portion 53 can be brought into contact with the cover member 4. In this way, since the force pressing the pressing member 33 is received by the cover member 4, it is possible to prevent the pressing force from being dispersed, and the force can be reliably transmitted to the bag body 1. With the above configuration, in the drug volatilizer according to the present embodiment, the inner bag 11 of the bag body 1 can be easily opened.

(2) For example, if an excessive external force is applied to the bag body 1 by the pressing member 33, the outer bag 12 may be torn. In this case, the drug may flow out from the torn outer bag 12. However, in the drug volatilizer according to the present embodiment, since the storage section 313 is provided below the bottom wall portion 31 of the container body 3, that is, the bag body 1, even if the drug leaks, FIG. 20 shows. As shown, the drug can be stored in the storage unit 313. Therefore, it is possible to prevent the drug from leaking to the outside of the container 2.

In particular, in this drug volatilizer, a through hole 311 is formed in the bottom wall portion 31 of the container body 3, but since a wall portion 312 is formed around the through hole 311, the container is stored in the storage portion 313. The drug is blocked by the wall portion 312. Therefore, it is possible to prevent the drug stored in the storage unit 313 from leaking from the through hole 311.

(3) For example, when a drug leaks from the bag body 1, the drug tends to flow along the edge of the bag body 1 toward the four corners of the bag body 1 due to surface tension. On the other hand, in the drug volatilizer of the present embodiment, the flow path 325 is formed in the side wall portion 32 of the container body 3 below the portion where the corner portion of the bag body 1 is arranged. Each of the flow paths 325 is inclined, and the lower end thereof is connected to the storage unit 313. Therefore, the drug leaking from the corner portion of the bag body 1 is received by the flow path 325 and then flows into the storage portion 313. Therefore, the drug leaking from the bag body 1 can be efficiently guided to the storage unit 313, and the drug can be prevented from leaking to the outside.

(4) Since the upper opening of the container body 3 is closed by the base 51, for example, when the drug leaks from the bag body 1, the drug is formed on the cover member 4 side, that is, the cover member 4 and the base 51. It is possible to prevent the flow to the space (second internal space) side.
