Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. 1 to 3 respectively show the configuration of an embodiment of a drug volatilizer according to the present invention.

The drug volatilizer 1 of the present embodiment has a container 2 that has an opening at the top and can store a liquid drug inside, and a core material that can be stored in the container 2 to suck and volatilize the liquid drug. 3 and a core material holding frame 4 capable of holding the core material 3. The upper opening of the container 2 is closed by a cap 5 so that it can be opened and closed. A core material holding frame 4 is rotatably connected to the cap 5, and the user can pull up the core material holding frame 4 from the container 2 by holding the cap 5. As the core material holding frame 4 is pulled up, the volatilized portion 31 of the core material 3 is pulled up from the inlet 21 to the outside of the container 2 and exposed. At this time, since the suction part 30 of the core material 3 is immersed in the medicine, the medicine sucked up by the suction part 30 of the core material 3 is volatilized outside the container 2 through the volatilization part 31 of the core material 3.

As shown in FIGS. 1 to 3, the container 2 includes a cylindrical neck portion 20 having the opening on the upper surface and a hollow body portion 22 continuous with the neck portion 20. The body portion 22 includes a shoulder portion 23 that has a larger diameter than the neck portion 20. Examples of the container 2 include a transparent plastic blow molded product, but may be an injection molded product in addition to a glass product.

A male screw portion 24 is provided on the upper outer peripheral surface of the neck portion 20. The cap 5 is fixed to the neck portion 20 of the container 2 by screwing the male screw portion 24 with the female screw portion 50 provided on the inner peripheral surface of the cap 5.

A pair of projecting

portions

25 and 25 projecting inward are integrally provided on the lower inner peripheral surface of the neck portion 20. Each protrusion part 25 is provided in the position which opposes, and each protrudes in the thickness direction of the core material 3, and opposes the front surface and rear surface with the largest area of the volatilization part 31 of the core material 3. As shown in FIG. Accordingly, an opening having a substantially rectangular shape in plan view along the outer shape of the volatilization portion 31 of the core material 3 is formed in the neck portion 20 by the two protrusion portions 25. The opening serves as an inlet 21 when the core material holding frame 4 holding the core material 3 is pulled up or inserted into the container 2.

Each protrusion 25 holds the core material holding frame 4 in an upright state when the core material holding frame 4 is pulled up. That is, when the core material holding frame 4 is pulled up, the tip surface of each protrusion 25 comes into contact with the core material holding frame 4 (the outer surface of each side frame member 40 described later) holding the core material 3. By sandwiching a part of the holding frame 4, the core material holding frame 4 is held in an upright state. Further, since the core material holding frame 4 is sandwiched by the protruding portions 25 protruding from the inner peripheral surface of the neck portion 20, a space is generated between the core material holding frame 4 and the inner peripheral surface of the neck portion 20. Therefore, the core material holding frame 4 can be tilted at least in the front-rear direction (the direction of each protrusion 25) with each protrusion 25 as a fulcrum.

The lower surface of each protrusion 25 is an inclined surface that inclines toward the inside. Moreover, the upper surface of each protrusion part 25 becomes the inclined surface which inclines low toward the inner side, and each protrusion part 25 has a taper-like shape as a whole. The portions that are continuous with the top surfaces of the upper and lower surfaces of the protrusions 25 are respectively smooth curved surfaces.

In addition, in this embodiment, although each protrusion part 25 is integrally provided in the neck part 20 of the container 2, it is not necessarily restricted to this structure. For example, each protruding portion 25 may be detachably provided in the form of an inner plug with respect to the inner peripheral surface of the neck portion 20 of the container 2.

A cylindrical boss 51 is provided on the inner bottom surface of the cap 5 so as to protrude from the inner bottom surface. The tip of the boss 51 is equally divided, and a plurality of (for example, three) engaging claws 52 are provided. A stepped portion 53 is provided on the outer surface of each engaging claw 52. The boss 51 can be fitted into a fitting hole 43 provided in the connecting portion 42 of the core material holding frame 4 to be described later, and each of the engaging claws 52 is elastically deformed inward so that the boss 51 is fitted into the fitting hole 43. Then, the core material holding frame 4 is rotatably connected to the cap 5 without coming off in the axial direction by hooking the stepped portion 53 of each engaging claw 52 to the lower surface of the connecting portion 42. .

As shown in FIGS. 4 to 6, the core material holding frame 4 is formed of a flexible material such as plastic, for example, and has a pair of left and right plate-like side frame members 40 extending downward. 40 and a horizontal plate-like upper frame member 41 that connects upper end portions of the side frame members 40 to each other. A connecting portion 42 is integrally provided at the center of the upper frame member 41, and a fitting hole 43 is provided at the center of the upper surface of the connecting portion 42. The upper end portion of each side frame member 40 is formed to be wide, and L-shaped opening and

closing members

44 and 44 for opening and closing each side frame member 40 are integrated with the upper end portion of each side frame member 40. Is provided.

In the state where each side frame member 40 hangs downward, the distance between each side frame member 40 is set slightly smaller than the thickness of the volatilization portion 31 of the core material 3. Thus, the core member 3 is held by the core member holding frame 4 so that the volatilization portion 31 is sandwiched between the side frame members 40 and the suction portion 30 is suspended from each side frame member 40. Each side frame member 40 is elastically swingable with the upper end portion 40A as a fulcrum and can be opened and closed. For example, each side frame member 40 has a thumb on the upper surface of the cap 5 (shown in FIG. An index finger and a middle finger are respectively applied to the bottom surface 44A of the opening and closing member 44, and each opening and closing member 44 is pressed toward the direction of the cap 5 (the direction of the arrow P shown in FIG. 4), whereby the lower end portion of each side frame member 40 40B separates (opens) from each other. Thereby, the volatilization part 31 of the core material 3 can be inserted between the side frame members 40. And if the press with respect to each opening-and-closing member 44 is cancelled | released, each side frame member 40 will reset (close operation) to the state which hangs down to the original downward direction by the restoring force by elastic deformation, and will volatilize 31 of the core material 3 Hold it. Further, after the core material 3 is used, similarly, each opening / closing member 44 is pressed toward the direction of the cap 5 (direction of arrow P shown in FIG. 4) to open each side frame member 40. Thus, the holding by the side frame members 40 with respect to the core material 3 is released. As a result, the used core material 3 can be easily detached from the core material holding frame 4.

In the present embodiment, the entire volatilization portion 31 of the core material 3 is held by the core material holding frame 4. When the core material holding frame 4 is inserted into the container 2, each side frame member 40 is sandwiched between the projecting portions 25 of the container 2, so that each side frame member 40 is opened and closed by each opening / closing member 44. Operation is restricted. Therefore, the core material 3 cannot be removed from the core material holding frame 4 unless the core material holding frame 4 is pulled out from the inlet 21 of the container 2.

The lower end portion 40B of each side frame member 40 is formed wide, and one side edge portion in the width direction is bent inward to provide a first bent portion 45. A predetermined region from the lower end portion of the first bent portion 45 is bent into a “<” shape so as to follow the shape of the lower surface of the volatilization portion 31 of the core material 3, and a part of the lower surface of the volatilization portion 31 is formed. The supporting support surface 46 is constituted. The first bent portion 45 supports one side surface of the core material 3 sandwiched between the side frame members 40, and the support surface 46 restricts the core material 3 from being displaced downward. Yes. Further, a part of the upper part of each side frame member 40 is formed to be wide, and one side edge in the width direction is bent inward to provide a second bent portion 47. Yes. The second bent portion 47 supports the other side surface of the core member 3 sandwiched between the side frame members 40.

The lower end portion 40B of each side frame member 40 is integrally provided with outward engaging

projections

48, 48 protruding from the plate surface at the center portion of the outer surface thereof. Each engagement protrusion 48 is provided so as to protrude in the direction of the protrusion 25 inside the container 2. Therefore, when the core material holding frame 4 is pulled up when the chemical volatilizer 1 is used, each engagement projection 48 is hooked on and engaged with the lower surface of each protrusion 25 of the container 2. Thereby, the core material holding frame 4 is prevented from coming off, and the core material holding frame 4 is prevented from coming out from the inlet 21 of the container 2.

An insertion guide portion 48A is provided at the lower edge of each engagement protrusion 48 so as to be inclined downward from the outside to the inside. The core material holding frame 4 is once pulled out from the inlet 21 of the container 2 for refilling the medicine or replacing the core material 3, and then inserted when the core material holding frame 4 is inserted into the container 2 from the inlet 21 again. Each engagement protrusion 48 is easily bent inward by the presence of the guide portion 48 </ b> A, so that each engagement protrusion 48 easily gets over each protrusion 25. As a result, the core material holding frame 4 can be easily inserted into the container 2.

A plurality (three in the illustrated example) of protrusions 49 are integrally provided on the outer surface of each side frame member 40 at equal intervals in the vertical direction. Each protrusion 49 engages with the upper surface of each protrusion 25 provided on the inner peripheral surface of the neck 20 of the container 2 when the core material holding frame 4 is pulled up, so that the core material holding frame 4 is in the container. 20 is not inadvertently depressed. Thereby, the core material holding frame 4 can be held at a predetermined height position.

As shown in FIGS. 7A and 7B, the core 3 includes a substantially rectangular parallelepiped suction part 30 and a volatilization part 31, and the suction part 30 and the volatilization part 31 are continuously integrated. It has the form which was made. The core 3 is entirely composed of a fiber layer (not shown) that is excellent in the effect of sucking and volatilizing a liquid drug. The fiber layer can be composed of a fibrous material such as natural fibers such as plant fibers or pulp, synthetic fibers such as rayon, polyester, PET (polyethylene terephthalate), PP (polypropylene), or mixed fibers thereof. . In particular, a nonwoven fabric manufactured by an airlaid method, a needle punch method, a spunbond method, a spunlace method, or the like is suitable, but other layers such as a woven fabric and a knitted fabric may be used. In addition, you may comprise so that the coating layer comprised with the thin rayon, for example may be provided in the surface of the said fiber layer.

In the present embodiment, the suction portion 30 is formed so that its width is narrower than that of the volatilization portion 31. Thereby, when the core material holding frame 4 is accommodated in the container 2, the suction part 30 is folded, and when the core material holding frame 4 is pulled up, the suction part 30 is extended. Each can be easily deformed (see FIGS. 1 and 2). The suction portion 30 is set to a length that can reach the inner bottom surface of the container 2 when the core material holding frame 4 is pulled up, and can suck up the medicine to the end. Further, the volatilization part 31 is formed to be wide so that the chemical is easily volatilized in the air when the core material holding frame 4 is pulled up. In addition, in this embodiment, although the width | variety of the suction part 30 is made narrower than the width | variety of the volatilization part 31, the width | variety of the suction part 30 and the volatilization part 31 may be the same magnitude | size.

Next, a method of using the chemical volatilizer 1 having the above configuration will be described.

In the chemical volatilizer 1 having the above-described configuration, in the state where the cap 5 is fixed to the neck 20 of the container 2, as shown in FIG. 2, the core 3 has the suction part 30 and the volatilizing part 31 in the liquid chemical. I'm immersed. On the other hand, as shown in FIG. 1, when the cap 5 and the neck portion 20 of the container 2 are unfixed and the cap 5 is pulled up from the container 2, the core material holding frame 4 is pulled up from the inlet 21 of the container 2. Thus, the volatilization portion 31 of the core material 3 is exposed to the outside of the container 2. Thereby, the chemical | medical agent sucked up by the suction part 30 via the volatilization part 31 is volatilized in the air. At this time, a plurality of protrusions 49 are provided on the outer surface of each side frame member 40 of the core material holding frame 4, and when each of the protrusions 49 pulls up the core material holding frame 4, the container It engages with the upper surface of each projecting portion 25 provided on the inner peripheral surface of the second neck portion 20. Thereby, the core material holding frame 4 is not inadvertently dropped into the container 2, and the core material holding frame 4 can be held at a desired lifting height. Therefore, the user can change the surface area of the volatilization part 31 exposed outside, and can adjust the volatilization amount of a chemical | medical agent.

Further, when the core material holding frame 4 is pulled up, the front end surface of each protrusion 25 comes into contact with each side frame member 40 of the core material holding frame 4, so that the core material holding frame 4 is held upright. Further, since the engaging protrusions 48 of the side frame members 40 are securely hooked and engaged with the lower surface of the protruding portion 25 of the container 2, even if the user accidentally pulls the core material holding frame 4 too strongly, the core The material holding frame 4 is prevented from being inadvertently pulled out from the inlet 21 of the container 2.

On the other hand, when the chemical in the container 2 becomes small due to the volatilization of the chemical, or when the volatilization performance of the chemical deteriorates due to clogging of the non-volatile component such as a surfactant in the core 3, After the material holding frame 4 is pulled up until each engaging protrusion 48 engages with each protruding portion 25, the material holding frame 4 is tilted forward or rearward (in the direction of each protruding portion 25 indicated by arrow X1 or arrow X2 in FIG. 1). By doing so, the core material holding frame 4 can be easily pulled out from the inlet 21 of the container 2.

In other words, in the chemical volatilizer 1 of the present embodiment, each engagement protrusion 48 of the core material holding frame 4 is provided so as to protrude in the direction of each protrusion 25 that can tilt the core material holding frame 4. Therefore, when the core material holding frame 4 is tilted, the engagement protrusion 48 on the tilted side is displaced inward and downward to disengage from the protruding portion 25. Here, when the core material holding frame 4 is further lifted in a state in which the core material holding frame 4 is tilted (that is, in a state where the engagement protrusion 48 and the protruding portion 25 are disengaged), Only the engaging protrusion 48 that engages with the protruding portion 25 of the container 2 on the opposite side receives the inward pressing force by the reaction force from the protruding portion 25. As a result, the side frame member 40 bends due to elastic deformation, so that the engagement protrusion 48 (the lower end portion 40B of the side frame member 40) on the opposite side to the inclined side is displaced inward, and the engagement with the protrusion 25 is performed. It will come off and easily get over the protrusion 25. Thereafter, the other engaging projection 48 on the inclined side is easily pulled out of the inlet 21 of the container 2 by overriding the protruding portion 25 by pulling up the core material holding frame 4. Is possible.

In the present embodiment, since the lower surface of each protrusion 25 is an inclined surface that is highly inclined inward, each engaging protrusion 48 is pulled out when the core material holding frame 4 is pulled out from the inlet 21 of the container 2. However, it is easily displaced inward along the lower surface of the protrusion 25. Therefore, each engagement protrusion 48 can easily get over each protrusion 25 of the container 2. Moreover, since the upper surface of each protrusion part 25 becomes the inclined surface which inclines low toward inward, after pulling out the core material holding frame 4 from the inlet 21 of the container 2, once again, the core material holding frame 4 is made into the inlet. Also when inserting into the container 2 from 21, the respective engaging projections 48 are easily displaced inward along the upper surface of the projecting portion 25 so as to easily get over each projecting portion 25. 4 is easy to insert.

Thus, in the chemical volatilizer 1 of the present embodiment, the core material holding frame 4 is moved to the container 2 by a simple operation of pulling up the core material holding frame 4 while tilting the core material holding frame 4 in either the front-rear direction. Therefore, the refilling of the medicine and the replacement work of the core material 3 can be easily and easily performed. Further, the container 2 and the core material holding frame 4 can be reused by replenishing the container 2 with a new medicine or replacing the core material 3 of the core material holding frame 4 with a new core material. It is.

Further, when it is desired to replace the core material 3 of the core material holding frame 4 with a new core material, the core material holding frame 4 is pulled out from the container 2 and then each opening / closing member 44 is moved using, for example, an index finger and a middle finger. Press in the direction of the cap 5. Thereby, each side frame member 40 opens and the state which clamps the core material 3 is cancelled | released. As a result, the user can easily remove the used core material 3 from the core material holding frame 4 without touching the medicine, and the core material 3 can be easily replaced with the core material holding frame 4. be able to.

Although one embodiment of the present invention has been described above, specific aspects of the present invention are not limited to the above-described embodiment. In the above-described embodiment, one engagement protrusion 48 is provided at each lower end portion of each side frame member 40 of the core material holding frame 4, but two or more plural may be provided, Further, the number of engaging protrusions 48 provided on each side frame member 40 may be different.
