Description

  The present invention relates to a drug volatilizer in which a liquid drug having various volatility such as a fragrance and a deodorant is contained in a container and a core material capable of sucking and volatilizing the drug is immersed in the drug.

  In order to eliminate the discomfort caused by odors in rooms and automobiles and create comfortable spaces, chemical volatilizers that volatilize liquid chemicals naturally are widely used. This type of drug volatilizer is generally composed of a container for storing a drug and a core material capable of sucking and volatilizing the drug stored in the container. The core material is partially immersed in the drug, while the other part (volatilization part) can be exposed to the outside through the opening at the top of the container. The chemical is volatilized in the air at the volatilization part.

  An example of the chemical volatilizer having the above configuration is disclosed in Patent Document 1. As shown in FIGS. 22 to 24, the drug volatilizer 100 described in Patent Document 1 includes a container 110 that stores a liquid drug, a strip-shaped core material 102 that is stored in the container 110, and a core material 102. It is comprised by the core material holding frame 101 to hold | maintain. The core material 102 is provided so as to connect each side frame member 103 to a pair of vertical plates 104 provided on a pair of side frame members 103 constituting the core material holding frame 101 and a lower end portion of each side frame member 103. The one end portion of the core member 102 is passed between the connecting member 105 and a pair of receiving rods 106 provided at the lower end portions of the side frame members 103, and is wound downwardly. The bottom of the container 110 is reached by being hung down. The core material holding frame 101 is connected to a cap 108 that can close the opening 110 </ b> A of the container 110. Then, the cap 108 is removed from the container 110, and the core material holding frame 101 is pulled up via the cap 108, so that the volatilization portion 102 </ b> A on the core material is exposed to the outside of the container 110. Therefore, the volatilization state of the medicine sucked up by the suction part 102B at the lower part of the core material can be adjusted according to the degree of exposure of the volatilization part 102A. At this time, a part of the neck 110C of the container 110 is constricted inward to form a pair of protrusions 109 that protrudes inwardly. The leading end surface of the projecting portion 109 comes into contact with the surface of the volatilizing portion 102A and sandwiches the core material 102, whereby the core material holding frame 101 is held upright. Further, a projection 107 protruding outward is provided at the lower end of each side frame member 103. When the core material holding frame 101 is pulled up, the protrusions 107 are hooked and engaged with the shoulder portions 110B of the container 110, so that the core material holding frame 101 is prevented from easily coming out of the container 110.

Registered Utility Model Publication No. 3020459

  In the drug volatilizer described in Patent Document 1 described above, the connecting member 105 that connects each side frame member 103 in the vicinity of the lower end portion is bent inward at the lower end portion of each side frame member 103, and each projection 107 is positioned inside. It also plays the role of a “slip bar” that regulates the displacement. Thereby, at the time of use, each protrusion 107 is caught on the shoulder part 110 </ b> B of the container 110, and the core material holding frame 101 is prevented from coming out of the container 110. On the other hand, when the core material holding frame 101 is pulled out from the container 110 when the refilling of the medicine or the core material 102 is performed, the connecting member 105 is formed in an elongated rod shape having a square shape in cross section as shown in FIG. Therefore, each protrusion 107 can be displaced inward by being easily bent in the vertical direction ST shown in FIG. 25, and as a result, the engagement between each protrusion 107 and the shoulder 110B of the container 110 is released. Thus, the core material holding frame 101 can be pulled out from the container 110.

  However, since the connecting member 105 is a long and narrow bar having a square shape in cross section, the connecting member 105 is easily bent in the depth direction XY shown in FIG. 25. For example, the core material holding frame 101 is shown in FIG. 25, the connecting member 105 is easily bent in the depth direction XY shown in FIG. 25, and the direction of the core material holding frame 101 (core material 102) is changed. As a result, the front end surface and the volatilization portion of each protrusion 109 A gap is generated between the surface of 102A. When the drug volatilizer 100 falls down in a state where this gap is generated, there is a problem that the drug leaks from the gap.

Further, when the core member 102 is wound between the vertical plate 104 of the core member holding frame 101 and the connecting member 105, generally, the core member 102 is placed on the opposite side at the position of the connecting member 105 which is the lower end of the winding. it core member 102 is bent with the folding, since this bent portion is compressed by the core 102 is bent, than the total thickness of the total thickness T of the core material 102 is at a height the center position of the volatilized portion 102A getting thin. Therefore, the connecting member 105 is positioned between the protruding portions 109 of the neck portion 110C when the core material holding frame 101 is pulled up to the maximum, so that depending on the thickness of the core material 102, the surface of the core material 102 and the protruding portion 109 There was also a problem that a gap may be formed between the distal end surface and the medicine may leak when the medicine volatilizer 100 falls down.

  This invention was made paying attention to the above-mentioned subject, and even if a chemical volatilizer falls down at the time of use, it aims at providing the chemical volatilizer which can reduce the quantity which a chemical | medical agent leaks out.

The object of the present invention includes a container that can store a liquid medicine, a core material that is stored in the container and sucks and volatilizes the medicine, and a core material holding frame around which the core material is wound up and down. The core material holding frame is a drug volatilizer that volatilizes the drug sucked up by the core material out of the container by pulling a part of the core material out of the container, and the core material holding frame is comprising a pair of side frame members, and a connecting member to which the conjunction provided as to connect the respective side frame members at the bottom of each side frame member rolling up the core material, wherein the connecting member, the connecting member itself vertically This is achieved by a chemical volatilizer configured to be restricted to be bent in the depth direction perpendicular to the lateral width direction between the side frame members rather than the direction.

  According to the chemical volatilizer having the above-described configuration, the connecting member that winds up the core material when the core material is wound around the core material holding frame is configured to bend easily in the vertical direction but to bend in the depth direction. Therefore, when the chemical volatilizer is used, even if an external force in the depth direction acts on the connecting member due to, for example, the core holding frame being twisted, the connecting member is restricted from bending and elastically deforming in the depth direction. The Therefore, even when the core material holding frame is twisted at the time of use, the connecting member is easily bent in the depth direction and the orientation of the core material holding frame (core material) is different from the connecting member of the conventional chemical volatilizer. It does not change easily, and as a result, the normal use state is maintained for the drug volatilizer. Therefore, even when the medicine volatilizer falls down, the amount of medicine leaking out of the container can be reduced.

  In a preferred embodiment of the present invention, the connecting member is characterized in that the bending in the depth direction is restricted by forming the dimension in the depth direction larger than the dimension in the vertical direction. According to this embodiment, since the rigidity of the connecting member in the depth direction is increased, the connecting member is restricted from being bent in the depth direction, while the vertical dimension is set to be small. Since the rigidity of the connecting member is lowered, the connecting member is easily bent. The configuration for restricting the bending of the connecting member in the depth direction is not necessarily limited to the above-described embodiment. For example, the connecting member is formed by combining a hard substance having high rigidity and a flexible substance having low rigidity. As a result, the connecting member may be configured such that the rigidity in the vertical direction is low and is easy to bend, but the rigidity is high in the depth direction and the bending is restricted.

  In a further preferred embodiment of the present invention, a pair of projecting portions projecting inward are provided on the inner peripheral surface of the neck portion of the container, and the surface of the core material and the projecting portion are located at the position of the connecting member. The dimension of the connecting member in the depth direction is set so that the front end surface of the connecting member comes into contact with the front end surface.

  Generally, at the position of the connecting member, which is the lower end of the winding of the core material, the core material is compressed by the amount of bending of the core material as the core material is folded back to the opposite side. It becomes thinner than the total thickness at the center of the height of the material. Therefore, depending on the thickness of the core material, in the conventional chemical liquid volatilizer, there was a gap between the surface of the core material and the tip surface of the protruding portion of the neck of the container, according to this embodiment, Since the depth dimension of the connecting member is large and wide, the total thickness of the core member can be increased at the position of the connecting member where the total thickness of the core member tends to be thin. Therefore, the surface of the core material can be satisfactorily brought into close contact with the tip surface of the protruding portion, so that it is possible to reliably prevent a gap from being generated between the tip surface of the protruding portion and the surface of the core material. As a result, even when the drug volatilizer falls down during use, the amount of drug leaking from the container can be reduced.

  In a further preferred embodiment of the present invention, each side frame member has an engaging projection that engages the inside of the container and keeps the core material holding frame in a retaining state when the core material holding frame is pulled up. The connecting member is located between the protrusions when the engaging protrusion is engaged. According to this embodiment, the connecting member is positioned between the protruding portions of the neck when the core material holding frame is pulled up to the maximum, and the connecting member is formed wide in the depth direction. The surface of the core material and the tip end surface of the protruding portion are in good contact with each other, and a gap is prevented from being generated between the surface of the core material and the tip end surface of the protruding portion when the chemical volatilizer is used. As a result, even when the medicine volatilizer falls down, the amount of medicine leaking from the container can be reduced.

  According to the chemical volatilizer of the present invention, even if the chemical volatilizer falls down during use, the amount of the internal chemical leaking out can be suppressed.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 and FIG. 2 show the entire configuration excluding the core material of the drug volatilizer 1 according to an embodiment of the present invention. FIG. 3 is a plan view of the medicine volatilizer 1 with the cap 5 removed from the container 2. In the following description, as shown in FIGS. 1 to 3, the ST direction is the vertical direction, the UV direction between the side frame members 40 is the horizontal width direction, and the XY direction is the depth direction.

  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 (shown in FIG. 4) stored in the container 2, and a core. And a core material holding frame 4 for holding the material 3. 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 part 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, and the suction part 30 of the core material 3 is immersed in the medicine. Therefore, 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.

  The container 2 includes a cylindrical neck portion 20 having the opening 21 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 recessed portion 20A that is slightly recessed inward (in the UV direction) is formed on the lower inner peripheral surface of the neck portion 20, and a portion of the recessed portion 20A is directed inward (in the XY direction). A pair of projecting portions 25 projecting greatly are provided integrally. Each protrusion 25 is provided at a position facing each other, and is provided so as to protrude in the thickness direction of the core material holding frame 4, that is, in the thickness direction of the core material 3. As a result, an opening 26 having a substantially rectangular shape in plan view is formed in the neck 20 (opening 21) by each protrusion 25. The opening 26 serves as an outlet when the core material holding frame 4 holding the core material 3 is pulled up or an inlet when the core material holding frame 4 is inserted into the container 2. Further, when the core material holding frame 4 is pulled up, the tip surface of the projecting portion 25 comes into surface contact with the surface of the volatilization portion 31 of the core material 3 held by the core material holding frame 4 so as to sandwich the volatilization portion 31. The core material holding frame 4 is held in an upright state.

  As shown in FIGS. 1 to 4, the core material holding frame 4 is formed of a flexible material such as plastic, and includes a pair of left and right side frame members 40 and 40. 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 at positions above the horizontal rails 44 above the side frame members 40, and the vertical plates 46 are not connected to each other and are not connected to each other. Are provided so as to face each other with an interval of. In addition, a connecting member 47 that connects the side frame members 40 is integrally provided at a position below the lower horizontal rail 45.

  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 pulling up the core material holding frame 4, the core material holding frame 4 can be easily removed from the container 2 by engaging the engaging protrusions 48 with the shoulder portions 23 of the container 2. It is prevented from coming out. In addition, when each engaging protrusion 48 is hooked on the shoulder 23 and the core material holding frame 4 is pulled up to the maximum extent, the connecting member 47 of each side frame member 40 is located between each protruding portion 25 of the neck portion 20 of the container 2. The connection member 47 is provided in each side frame member 40 so that it may be located in each.

  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 (ST direction). Each protrusion 49 engages with the upper edge of the inner surface of the recess 20 </ b> A provided in the neck 20 of the container 2 when the core material holding frame 4 is pulled up. Thereby, the core material holding frame 4 does not fall into the container 2 carelessly, and the core material holding frame 4 can be held at a predetermined height position.

  In the chemical volatilizer 1 according to this embodiment having the above-described configuration, the point that is greatly different from the conventional chemical volatilizer 100 (shown in FIGS. 22 to 24) is the configuration of the connecting member 47 of the core material holding frame 4. In the drug volatilizer 1 of the present embodiment, the connecting member 47 is configured to bend easily in the vertical direction ST but is restricted to be bent in the depth direction XY.

  Specifically, in this embodiment, as shown in FIG. 5, the dimension (depth dimension) d1 of the connecting member 47 in the depth direction XY is wider (cross-sectional view) than the dimension (height dimension) d2 in the vertical direction ST. It is formed in a rectangular shape. As a result, the rigidity of the connecting member 47 in the depth direction XY is increased, so that the connecting member 47 is restricted from bending in the depth direction XY, and even if an external force acts on the connecting member 47 from the outside in the depth direction XY. It is difficult to elastically deform. On the other hand, in the vertical direction ST, since the height dimension d2 is set small, the rigidity of the connecting member 47 is low and the connecting member 47 is easily bent. Therefore, in the vertical direction ST, it is possible to be elastically deformed by the external force acting on the connecting member 47, and the lower end portion of each side frame member 40 can be bent inward (lateral width direction UV). Yes.

  The dimensions d1 and d2 of the connecting member 47 are not particularly limited, but the height dimension d2 is preferably 3 mm or less from the viewpoint of easily bending the connecting member 47 in the vertical direction ST. It is more preferable that it is in the range of 0.5 mm to 2 mm from the viewpoint of easy forming.

  The depth dimension d1 is preferably larger than 2 mm, more preferably 3 mm or more, from the viewpoint of improving the rigidity of the connecting member 47 in the depth direction XY and making the connecting member 47 difficult to bend in the depth direction XY. More preferably, it is 5 mm or more. Here, the larger the depth dimension d1, the higher the rigidity of the connecting member, and the total thickness T at the position of the connecting member 47 of the core material 3 wound around the core material holding frame 4 (shown in FIG. 4). Is increased. When the core material 3 is wound between the two vertical plates 46 of the core material holding frame 4 and the connecting member 47, generally, the core material 3 is folded back to the opposite side at the position of the connecting member 47 which is the lower end of the winding. Accordingly, the core material 3 is compressed as much as the core material 3 is bent, and the total thickness T of the core material 3 becomes thinner than the total thickness at the height center portion of the core material 3. Since the connecting member 47 is positioned between the protrusions 25 of the neck 20 when the core material holding frame 4 is pulled up to the maximum when the chemical volatilizer 1 is used, the depth dimension d1 of the connecting member 47 is small (for example, 2 mm). When the connecting member 47 is positioned, depending on the thickness of the core material 3, a gap is formed between the surface of the core material 3 and the front end surface of each protrusion 25, and the drug leaks when the container 2 falls down. There is a risk of getting out. However, in the present embodiment, since the depth dimension d1 of the connecting member 47 is set large, the total thickness T of the core material 3 at the position of the connecting member 47 increases accordingly. Therefore, it is possible to prevent the above-described gap from being generated, and it is possible to reduce the amount of medicine that leaks when the container 2 falls down. On the other hand, if the depth dimension d1 of the connecting member 47 is set too large, the friction between the surface of the core material 3 and the front end surface of each protrusion 25 increases, and therefore the core material holding frame 4 is difficult to lift. The depth dimension d1 of the connecting member 47 is not compatible with the thickness of the core material 3 (for example, 6 mm) and the size of the opening 26 in the neck portion 20 (for example, 16 mm). It is preferable that the dimensions are set so that they can be pulled up without any problem. The depth dimension d1 of the connecting member 47 is preferably 4 mm or more and 8 mm or less, for example, in the thickness of the core member 3 or the size of the opening 26 described above.

  In the example of FIG. 5, the depth dimension d1 of the connecting member 47 and the width D of the side frame member 40 are the same. On the other hand, as shown in FIGS. 6 and 7, the depth dimension d1 of the connecting member 47 can be formed smaller than the width D of the side frame member 40, that is, both side edges of the connecting member 47 are side frame members 40. It may be formed so as not to protrude from both side edges. Further, as shown in FIG. 8, the depth dimension d <b> 1 of the connecting member 47 can be formed larger than the width D of the side frame member 40, that is, both side edges of the connecting member 47 are from both side edges of the side frame member 40. You may form so that it may protrude. Further, the cross-sectional shape of the connecting member 47 is not necessarily rectangular as in the example of FIG. 5, and can be formed in various shapes such as an inverted trapezoidal shape as shown in FIG. As shown in FIG. 6, when the cross-sectional shape is formed in a shape other than the rectangular shape, the depth dimension d1 of the connecting member 47 is the portion with the shortest depth dimension (see FIG. 6). In the example, the length of the lower base) is defined as the depth dimension d1, and the depth dimension d1 of the shortest portion may be set larger than the height dimension d2 of the connecting member 47.

  Further, the shape of the connecting member 47 in plan view is not necessarily rectangular as in the example of FIG. 5. For example, as shown in FIG. 9, both side edges 47 a of the connecting member 47 are convex outward. 10 and 11, for example, a shape in which a concave groove 47A is provided on one or both side edges (the central portion in the illustrated example) of the connecting member 47, or As shown in FIG. 12, for example, one or a plurality of convex protrusions 47B (two in the illustrated example) are provided on one or both side edges (both side edges in the illustrated example) 47 of the connecting member 47. It can be formed into various shapes such as a shape. 9 to 12, even when the planar view shape is formed in a shape other than the rectangular shape, the depth dimension d1 of the connecting member 47 is the shortest depth dimension of the connecting member 47, respectively. The length of the part is defined as a depth dimension d1, and the depth dimension d1 of the shortest part may be set larger than the height dimension d2 of the connecting member 47.

  Further, the connecting member 47 does not necessarily have a flat plate shape as in the example of FIG. 5, and a part of the inside of the connecting member 47 is cut off as shown in FIG. The cavity 47C may have a shape), and as shown in FIGS. 14 and 15, a part of the connecting member 47 (the center in FIG. 14) protrudes upward (or downward). May be curved in a convex shape, or may be curved in a convex shape upward or downward at a plurality of locations (two locations in FIG. 15), or a part of the connecting member 47 as shown in FIG. It may have a shape curved in a convex shape in the upper and lower fork at (the center in FIG. 16).

  Further, as shown in FIG. 17, the connecting member 47 may have a shape in which a plurality of horizontal flat plate-like first connecting members 47D are provided vertically (two steps in FIG. 17). As shown in FIGS. 18 to 20, a shape in which a flat plate-like second connecting member 47E is combined with a horizontal flat plate-like first connecting member 47D, for example, an L-shaped cross-sectional view (see FIG. 18), T-shaped (FIG. 19), substantially U-shaped (FIG. 20), and the like. In the case of the example shown in FIGS. 18 to 20, the height d2 of the connecting member 47 is the height d2 of the horizontal first connecting member 47D, and this horizontal first The height dimension d2 of the connecting member 47D only needs to be set smaller than the depth dimension d1 of the connecting member 47.

  6 to 20 described above, the rigidity of the connecting member 47 in the depth direction XY can be increased, while the rigidity of the connecting member 47 in the vertical direction ST can be decreased. Although it is easy to bend to the direction ST, it can comprise so that bending may be controlled to the depth direction XY. The shape of the connecting member 47 is not limited to the above example, and besides the above example, the rigidity in the depth direction XY can be increased and the rigidity in the vertical direction ST can be decreased, so that the vertical direction As long as it can be easily bent to ST and can be controlled to be bent in the depth direction XY, it can be formed into various shapes.

As shown in FIG. 21, 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. Moreover, the volatilization part 31 is formed so that the width | variety becomes narrower than the width | variety of the suction part 30, and the transition part 32 of the volatilization part 31 and the suction part 30 opposes so that a width | variety may narrow continuously. The side surface is formed in a tapered shape inclined toward the inside. Further, the suction portion 30 is formed in a tapered shape in which the opposite side surfaces are inclined so that the tip portion 30A continuously narrows in width, and in this embodiment, the tip portion 30A has a pointed tip. It is formed into a shape. The length of the volatilization part 31 and the suction part 30 is set so that the tip part 30A of the suction part 30 can reach the inner bottom surface of the container 2 when the core material holding frame 4 is pulled up to the maximum. In the present embodiment, the volatilization portion 31 is set to be significantly longer than the suction portion 30. As the size of the core material 3, the thickness is preferably about 6 mm. Moreover, it is preferable that the width of the volatilization part 31 is about 39 mm, and the width of the suction part 30 is about 19.5 mm. The length of the volatilization part 31 is about 270 mm and the length of the suction part 30 is about 45 mm (including the length of the transition part 32 of 9.75 mm and the length of the tip part 30A of 9.75 mm). It is preferable that Further, the basis weight of the core material 3 is preferably about 600 g / m ² .

  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.

  The core material 3 having the above-described shape is prepared by preparing a core material mold 34 having a rectangular shape in plan view as shown by a one-dot chain line in FIG. 21, and cutting the core material mold 34 along the shape of the core material 3 described above. It is formed by going.

  As described above, the core material 3 of the present embodiment includes the suction part 30 and the volatilization part 31, and the transition part 32 between the volatilization part 31 and the suction part 30 is formed in a tapered shape in plan view. A tip portion 30A of the upper portion 30 is formed in a tapered shape in plan view. Therefore, according to the core material 3 of the present embodiment, the transition portion 32 of the core material 3 is formed in a tapered shape instead of a right angle in plan view, unlike the core material 102 (shown in FIG. 22) of the conventional example. Therefore, when the core material 3 is formed from the core material mold 34, the amount of the portion cut out from the core material mold 34 can be reduced as compared with the case where the transition portion 32 is formed in a right-angle shape in plan view. .

  Further, according to the core material 3 of the present embodiment, the tip portion 30A of the suction portion 30 is formed in a tapered shape in plan view, so that the tip portion 30A of the suction portion 30 is the corner of the peripheral portion of the inner bottom surface of the container 2. It can be delivered all over. As a result, the remaining amount of the medicine in the container 2 is reduced, and even when the medicine remains thinly spread on the inner bottom surface of the container 2, the medicine that is likely to remain on the peripheral edge of the inner bottom surface is sucked up by the tip portion 30 </ b> A of the suction portion 30. Therefore, the medicine in the container 2 can be sucked up efficiently without leaving it. In the illustrated example, the tip portion 30A of the suction part 30 is formed in a pointed shape, and the tip portion 30A is more likely to reach every corner of the peripheral edge of the inner bottom surface of the container 2. The point need not be sharp.

  Moreover, in the core material 3 of this embodiment, since the suction part 30 is formed narrowly, the suction part 30 can be easily deformed into a folded state or an extended state. The portion 30 </ b> A can be more efficiently delivered to the corners of the inner bottom surface of the container 2. Moreover, since the volatilization part 31 is formed wide, it can be made easy to volatilize a chemical | medical agent in the air at the time of use which pulled up the core material holding frame 4. FIG.

  The shape of the core material 3 is not limited to the shape shown in FIG. 21, and various shapes including the shape of the core material 102 (shown in FIG. 22) of the conventional example can be adopted. 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.

  FIG. 4 shows how to attach the core material 3 to the core material holding frame 4. First, one end portion of the core material 3 is passed between the horizontal rail 44 above the core material holding frame 4 and each vertical plate 46 and along the side surface of each vertical plate 46. Next, after the other end portion of the core material 4 is folded and rolled up at the lower edge of the lower connecting member 47, the core member 4 is further folded downward at the upper edge of each upper vertical plate 46. It passes between the intermediate part of the core material 3 and the receiving rods 43 that are laid along and hangs downward. As a result, the volatilization portion 31 is wound around the core material holding frame 4, the suction part 30 is suspended from the core material holding frame 4, and the core material 3 is attached to 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 the suction part 30 and the volatilization part 31 immersed in the liquid drug. On the other hand, 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 to the outside of the container 2. Is exposed to the outside of the container 2. Thereby, the medicine sucked up by the suction part 30 is volatilized in the air via the volatilization part 31. At this time, a pair of projecting portions 25 are provided on the inner peripheral surface of the neck portion 20 of the container 2, and when the front end surface of each projecting portion 25 lifts the core material holding frame 4, 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, when the chemical in the container 2 becomes small due to the volatilization of the drug or the volatilization performance of the drug decreases due to clogging of the non-volatile component such as a surfactant in the core material 3, After the material holding frame 4 is pulled up until each engaging projection 48 engages with the shoulder 23 of the container 2, the core material holding frame 4 is further lifted and the core material holding frame 4 is pulled out of the container 2, thereby Can be refilled and the core 3 can be replaced.

  According to the chemical volatilizer 1 of the present embodiment, the connecting member 47 that winds up the core material 3 when the core material 3 is wound around the core material holding frame 4 is easily bent in the vertical direction ST but is bent in the depth direction XY. Since it is configured to be regulated, even when an external force in the depth direction XY shown in FIG. 5 acts on the connecting member 47 when the chemical volatilizer 1 is used, for example, the core material holding frame 4 is twisted. The connecting member 47 is restricted from being elastically deformed by bending in the depth direction XY. Here, in the medicine volatilizer 100 of the conventional example (shown in FIGS. 22 to 24), since the connecting member 105 has a long and narrow bar shape with a square shape in cross section (see FIG. 25), it is easily bent in the depth direction XY and used. When the core material holding frame 101 is sometimes twisted, the connecting member 105 is easily bent in the depth direction XY and the direction of the core material holding frame 101 (core material 102) is changed. There was a gap between the surface of 102A. On the other hand, in the chemical volatilizer 1 of this embodiment, even if the core material holding frame 4 is twisted as a result of the bending of the connecting member 47 in the depth direction XY being restricted, the core material holding frame 4 ( The orientation of the core material 3) is unlikely to change, and therefore the state where the tip surface of each protruding portion 25 of the neck portion 20 is in contact with the surface of the volatilization portion 31 of the core material 3 is maintained, so that a gap is created between them. It is prevented. As a result, even when the medicine volatilizer 1 falls down, the amount of medicine leaking out from the container 2 can be reduced.

  Further, since the depth dimension d1 of the connecting member 47 is set to be large, generally, the connecting member at the lower end portion of the core material holding frame 4 in which the total thickness of the core material 3 tends to be thin because the core material 3 to be wound is bent. Even at the position 47, the total thickness T of the core material 3 can be increased. Therefore, when the core material holding frame 4 is pulled up to the maximum when the chemical volatilizer 1 is used, the tip surfaces of the protruding portions 25 of the neck portion 20 and the surface of the volatilized portion 31 of the core material 3 can be satisfactorily brought into close contact with each other. . As a result, it is possible to reliably prevent a gap between the two, so that the amount of drug leaking out of the container 2 can be reduced even when the drug volatilizer 1 falls down during use. .

  In addition, the connecting member 47 also serves as a “tension bar” that restricts the lower end portion of each side frame member 40 from bending inward and displacing the engaging protrusion 48 inward during use. The core material holding frame 4 is prevented from being easily pulled out from the container 2 while being held on the shoulder 23 of the container 2. On the other hand, since the connecting member 47 is easily bent in the vertical direction ST, when the core material holding frame 4 is strongly pulled out from the container 2 when the medicine is refilled or the core material 3 is replaced, the connecting member 47 is used. Is easily deflected in the vertical direction ST shown in FIG. 5, whereby the engagement protrusion 48 can be displaced inward. As a result, the core material holding frame 4 can be pulled out of the container 2 by releasing the engagement between the engagement protrusion 48 and the shoulder portion 23.

  As mentioned above, although one Embodiment of this invention was described, the specific aspect of the chemical volatilization device which concerns on this invention is not limited to above-described embodiment. For example, in the above-described embodiment, the connecting member 47 is provided integrally with each side frame member 40, but may be configured by a member different from each side frame member 40. In this case, by combining the connecting member 47 with a hard substance having high rigidity and a flexible substance having low rigidity, the connecting member 47 is easily bent with low rigidity in the vertical direction ST, but with high rigidity in the depth direction XY. May be formed to be regulated.
