  However, in the medicine volatilizer described in Patent Document 1, the side frame members 103 are connected to the inner side because the lower end portions of the side frame members 103 of the core material holding frame 101 are connected by the horizontal rails 105. Therefore, the protrusions 107 are prevented from moving inwardly. Thereby, each protrusion 107 is firmly hooked on the shoulder 100B without disengagement from the shoulder 100B of the container 100, so that the core material holding frame 101 is reliably prevented from coming off from the container 100. On the other hand, when the core material holding frame 101 is removed from the container 100, the engagement between the projections 107 and the shoulder portions 106 of the container 100 is not easily released. Can not be pulled out. Therefore, there is a problem that the refilling of the medicine and the replacement work of the core material 102 cannot be easily performed.

FIG. 4 shows a state where the core material 3 is attached to the core material holding frame 4 shown in FIGS.

  The drug volatilizer 1 of the present embodiment has a container 2 that has an opening 21 at the top and can store a liquid drug inside, a core material 3 that is stored in the container 2, and a core that holds the core material 3. And a material holding frame 4. The opening 21 of the container 2 is closed by a cap 5 so as to 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 volatilization portion 31 of the core material 3 is pulled up from the opening 21 of the container 2 and exposed to the outside of the container 2. Since the suction part 30 of the core material 3 is immersed in the chemical | medical agent at this time, the chemical | medical agent sucked up by the suction part 30 of the core material 3 volatilizes outside the container 2 through the volatilization part 31 of the core material 3 ( (Refer FIG.8 (b)).

  As shown in FIGS. 1 to 3, the container 2 includes a cylindrical neck 20 having the opening 21 on the upper surface and a hollow body 22 continuous to the neck 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 constricted surface 20A slightly constricted inward is provided on the entire inner periphery of the lower inner peripheral surface of the neck portion 20 at a portion adjacent to the shoulder portion 23. In addition, a pair of projecting portions 20B and 20B projecting greatly inward are provided integrally on a part of the constricted surface 20A. Each protruding portion 20 </ b> B is provided at an opposing position, and each protrudes in the thickness direction of the core material holding frame 4, that is, in the thickness direction of the core material 3. Accordingly, an opening having a substantially rectangular shape in plan view is formed in the neck portion 20 by the two protruding portions 20B. The opening serves as an inlet when the core material holding frame 4 holding the core material 3 is pulled up or inserted into the container 2.

  Each protrusion 20B 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 front end surface of each protrusion 25 comes into surface contact with the surface of the volatilization part 31 of the core material 3 held by the core material holding frame 4 so as to sandwich the volatilization part 31. Thus, the core material holding frame 4 is held in an upright state.

  In addition, in this embodiment, although each protrusion part 20B is integrally provided in the neck part 20 of the container 2, it is not necessarily restricted to this structure. For example, each protrusion 20B may be detachably provided in the form of an inner plug with respect to the inner peripheral surface of the neck 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 42 provided in the connecting member 41 of the core material holding frame 4 to be described later, and the boss 51 is fitted into the fitting hole 42 by elastically deforming each engaging claw 52 inward. Then, the core material holding frame 4 is rotatably connected to the cap 5 without coming off in the axial direction by hooking the step 53 of each engaging claw 52 to the lower surface of the connecting member 41. Yes.

  As shown in FIGS. 1 to 6, the core material holding frame 4 is formed of, for example, a flexible material such as plastic, and includes a pair of left and right side frame members 40, 40 and each side frame member 40. The connection member 41 which connects the upper end parts of each is provided. A fitting hole 42 is provided in the central portion of the connecting member 41. Reinforcing plates 43, 43 are integrally provided on both side portions of the connecting member 41, and side frame members 40 extending integrally below the container 3 are integrally provided on the reinforcing plates 43, respectively.

  Two horizontal bars 44 and 45 that connect the side frame members 40 are integrally provided at a substantially central portion of each side frame member 40. Further, inwardly facing vertical plates 46 and 46 are integrally provided on the inner surface of each side frame member 40 at an upper position than the upper horizontal rail 44, and the vertical plates 46 are connected to each other. And are provided so as to face each other at a predetermined interval. Also, inward vertical plates 47, 47 are integrally provided at a lower position than the lower horizontal rail 45, and the vertical plates 47 are also connected to each other with a predetermined interval without being connected to each other. It is provided to do.

  At the lower end of each side frame member 40, outwardly engaging projections 48, 48 projecting out of the frame are integrally provided on the outer surface thereof. When using the chemical volatilizer 1, when the core material holding frame 4 is pulled up, each of the engaging protrusions 48 is hooked and engaged with the shoulder 23 of the container 2, so that the core material holding frame 4 is in a retaining state. The core material holding frame 4 is prevented from coming out of the container 2 (see FIG. 8B).

  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 toward the inside. When the core material holding frame 4 is once pulled out of the container 2 for refilling the medicine or replacing the core material 3, the core material holding frame 4 is inserted again into the container 2 due to the presence of the insertion guide portion 48A. Each engagement protrusion 48 is easily bent inward, 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.

  Further, on the inner side surface of the lower end portion of each side frame member 40, inward regulating projections 49, 49 are integrally provided at a position opposite to the engagement projection 48, respectively. The restricting protrusions 49 are provided so as to face each other without being connected to each other. Each restricting projection 49 is provided with convex portions 49a on the end surfaces facing each other, and each projecting portion 49a has a height at which its tip abuts against the end surface of the other restricting projection 49 facing each other. Have.

In the present embodiment, each restricting protrusion 49 is provided with a convex portion 49a, and the restricting protrusion 49 abuts against the end surface of the other restricting protrusion 49, so that the restricting protrusions 49 come into contact with each other. However, it is not necessarily limited to this. For example, the restricting protrusions 49 may not be provided on the restricting protrusions 49, and the restricting protrusions 49 may come into contact with each other when the end faces of the restricting protrusions 49 abut each other .

  A plurality (three in the illustrated example) of protrusions 54 are integrally provided on the outer surface of each side frame member 40 at equal intervals in the vertical direction. Each of the protrusions 54 engages with the upper edge of the constricted surface 20A provided on the inner peripheral surface of the neck 20 of the container 2 when the core material holding frame 4 is pulled up. It is designed not to inadvertently fall inside. Thereby, the core material holding frame 4 can be held at a predetermined height position.

  In the core material holding frame 4 having the above-described configuration, the lower portion of the side rail 45 below each side frame member 40 is easily elastically deformed by the external pressing force, so that the core material holding frame is 4 can be bent in the curved direction in the width direction or thickness direction. Moreover, after bending, it returns to the state where it hangs downward by the restoring force by elastic deformation. However, when the chemical volatilizer 1 is used, the convex portions 49a of the restricting protrusions 49 abut against the end surfaces of the other restricting protrusions 49 facing each other, so that the lower side of each side frame member 40 The portion is restricted from being bent inward by elastic deformation. Here, when the core material holding frame 4 is pulled up, after each engaging projection 48 is caught on the shoulder 23 of the container 2, if the core material holding frame 4 is accidentally pulled up by the user, An inward pressing force acts on the mating protrusion 48 by receiving a reaction force from the shoulder portion 23 of the container 2. As a result, the lower portion of each side frame member 40 bends inward due to elastic deformation, whereby each engagement projection 48 is displaced inward, and the engagement between each engagement projection 48 and the shoulder 23 of the container 2. There is a risk of failure. However, in the core material holding frame 4 having the above-described configuration, each side frame member 40 is restricted from being bent inward by the respective restriction protrusions 49, so that each engagement protrusion 48 is connected to the shoulder portion 23 of the container 2. Even when the core material holding frame 4 is further pulled up by the user after the engagement, the engagement between the engagement protrusions 48 and the shoulder portion 23 of the container 2 is not released. This reliably prevents the core material holding frame 4 from coming out of the container 2.

  On the other hand, when it is desired to remove the core material holding frame 4 from the container 2 for refilling the medicine or replacing the core material 3, each of the engaging projections 48 is connected to the shoulder portion 23 of the container 2. After pulling up until it engages, the core material holding frame 4 is twisted in the direction of arrow T shown in FIG. Thereby, each side frame member 40 receives a reaction force from each protrusion 20B of the container 2 through the volatilization portion 31 of the core member 3, and is in the opposite direction (in the directions of arrows X and X 'shown in FIG. 5). The pressing force is applied. Therefore, the lower part of each side frame member 40 bends in the thickness direction of the core material holding frame 4 due to elastic deformation, so that the restricting projections 49 are displaced in the opposite directions and displaced. When the core material holding frame 4 is pulled up in this state, each engaging projection 48 receives an inward pressing force (in the directions of arrows Y and Y ′ shown in FIG. 5) by the reaction force from the shoulder 23 of the container 2. As a result, the lower portion of each side frame member 40 bends due to elastic deformation, whereby each engagement protrusion 48 is displaced inward and the engagement with the shoulder portion 23 of the container 2 is released. As a result, each of the engaging protrusions 48 easily gets over the shoulder 23 of the container 2, so that the core material holding frame 4 can be easily pulled out from the container 2.

  As shown in FIGS. 4 and 7, the core material 3 includes a suction part 30 and a volatilization part 31, and has a belt-like form in which the suction part 30 and the volatilization part 31 are continuously integrated. 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 this embodiment, the suction part 30 is formed so that the width | variety becomes narrower than the volatilization part 31. FIG. Thereby, when the core material holding frame 4 is accommodated in the container 2 (when the chemical volatilizer 1 is not used), the suction part 30 is folded, while the core material holding frame 4 is When pulled up (during use of the chemical volatilizer 1), the suction part 30 can be easily deformed into an extended state (see FIGS. 8A and 8B). The suction part 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, so that the medicine can be sucked up to the end. Moreover, the volatilization part 31 is formed wide so that the chemicals can be easily volatilized in the air when the core 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. Moreover, the shape of the core material 3 does not necessarily need to be a band shape, and various shapes can be adopted as long as the shape has a liquid drug wicking and volatilizing effect such as a cylindrical shape or a string shape.

  In order to attach the core material 3 to the core material holding frame 4, as shown in FIG. 4, first, one end portion of the core material 3 is connected to the horizontal beam 44 above the core material holding frame 4 and each vertical plate 46. Pass along the side of each vertical plate 46. Next, after the other end portion of the core material 4 is folded and wound up at the lower edge of each of the lower vertical plates 47, it is further folded back at the upper edge of each of the upper vertical plates 46. It passes between the middle part of the core material 3 along 47 and each regulating projection 49 and hangs downward. Thereby, the volatilization part 31 is wound around the core material holding frame 4, and the core material 3 is attached to the core material holding frame 4 so that the suction part 30 is suspended from the core material holding frame 4.

  Next, the usage method of the chemical volatilizer 1 of this embodiment is demonstrated.

  In the drug volatilizer 1 of the present embodiment, when the cap 5 is fixed to the neck 20 of the container 2, the core 3 has a liquid suction part 30 and a volatilization part 31 in a liquid state as shown in FIG. Soaked in the drug. On the other hand, as shown in FIG. 8B, 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 moved to the outside of the container 2. The core volatilization part 31 is exposed to the outside of the container 2 by being pulled up. 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 pair of projecting portions 20B are provided on the inner peripheral surface of the neck portion 20 of the container 2, and when the tip surface of each projecting portion 20B pulls up the core material holding frame 4, the core material 3 The surface of the volatilization part 31 is in surface contact. Thereby, the core material holding frame 4 can be held at a predetermined lifting height. Therefore, the user can adjust the volatilization amount of the medicine by adjusting the pulling height of the core material holding frame 4 and changing the surface area of the volatilization part 31 exposed to the outside.

  In addition, a plurality of protrusions 54 are provided on the outer surface of each side frame member 40 of the core material holding frame 4, and when each protrusion 54 pulls up the core material holding frame 4, the container 2 It engages with the upper edge of the constricted surface 20 </ b> A provided on the inner peripheral surface of the neck 20. This prevents the core material holding frame 4 from inadvertently falling into 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 pulling up the material holding frame 4 until each engaging projection 48 engages with the shoulder portion 23 of the container 2, the core material holding frame 4 is twisted (arrow T in FIG. 8B) to thereby form the core material holding frame. 4 can be easily pulled out of the container 2. Thus, in the medicine volatilizer 1 of the present embodiment, the core material holding frame 4 can be easily pulled out from the container 2 by a simple operation of twisting the core material holding frame 4, so that the refilling of the drug and the core material are possible. 3 can be easily replaced. 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.
