Therefore, the drug is difficult to volatilize from the outer peripheral surface of the gel-like drug 100, and the volatilization area where the drug volatilizes is limited. Therefore, there is a problem that the volatilization efficiency of the medicine is poor and the volatilization of the medicine from the gel-like medicine 100 is not performed smoothly. This is because the chemical volatilization container of the conventional example such as Patent Document 1 seals the lower end opening of the lid portion 102 with the pedestal portion 101, and then gels water into the lid portion 102 from the filling hole formed in the lid portion 102. The sol in which the gelling agent, the volatile substance, the deodorant / fragrance component, etc., which are the raw materials of the powdered drug 100 are dissolved or dispersed, is filled, and the sol in the lid 102 is cooled to be gelled. This is because it is placed on the pedestal 101. In this conventional method for producing a drug volatilization container, since the sol is gelled and molded into a shape corresponding to the shape of the lid 102 at the same time as cooling, the outer peripheral surface of the gel drug 100 is formed on the peripheral wall 103 of the lid 102.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1: has shown the longitudinal cross-sectional view of the chemical volatilization container 1 which concerns on one Embodiment of this invention. FIG. 2 is an enlarged cross-sectional view in which the engaging portion 6 between the pedestal portion 3 and the ring-shaped member 5 of the chemical volatilization container 1 in FIG. 1 is enlarged. The drug volatilization container 1 according to the present embodiment includes a solid or semi-solid drug 2, a pedestal 3 on which the drug 2 is placed, a lid 4 that covers the drug 2 on the pedestal 3, and a lid on the pedestal 3 And a ring-shaped member 5 for fixing the portion 4.

  The drug 2 is a gel-like drug that has volatility (medicine sustained release) and exhibits medicinal effects such as deodorization and aroma by volatilization in the air. For example, a gel-like drug is gelled (solidified or semi-solidified) by cooling a sol in which drug components such as a gelling agent, a surfactant, a volatile substance, and a deodorant / fragrance component are dissolved or dispersed in water. Solidified). Arbitrary things can be employ | adopted as a deodorizing and aroma component, For example, a natural fragrance | flavor, a synthetic | combination fragrance | flavor, an amphoteric surfactant type | system | group deodorant, a fatty-acid salt type | system | group deodorant etc. can be used.

In the present embodiment, the overall shape of the medicine 2 is a substantially truncated cone shape, and the lower portion is formed in a columnar shape, while the upper portion is formed in a truncated cone shape whose outer peripheral surface expands downward. Has been. The lower part of the medicine 2 is arranged in an annular wall 35 described later, and the upper part protrudes above the annular wall 35. The outer peripheral surface of the drug 2 (the outer peripheral surface of the upper portion protruding from the annular wall 35 in this embodiment) is inclined inwardly at a predetermined inclination angle theta ₂ with respect to the vertical plane V. The overall shape of the medicine 2 may be a complete truncated cone shape.

  As shown in FIGS. 1 and 3, the lid 4 is a cup-shaped cup having a circular shape in plan view with the upper end closed and the lower end opened, and has a storage space 40 in which the medicine 2 can be stored. Yes. A flange portion 45 extending outward is integrally provided at the periphery of the lower end opening of the lid portion 4. The peripheral wall 41 of the lid 4 is provided with at least one (for example, three) volatilization holes 42 for releasing the chemical volatilized from the internal chemical 2 (volatile chemical) to the outside. The volatilization hole 42 is closed by a cover member 43 before the chemical volatilization container 1 is used. The cover member 43 is provided on the peripheral wall 41 by forming a perforation 44 having a predetermined shape (for example, a U shape, a U shape, an arc shape, etc.) on the peripheral wall 41 of the lid portion 4. The volatilization hole 42 is formed by breaking the perforation 44 and rotating the cover member 43 with respect to the peripheral wall 41. In addition, it is preferable that each volatilization hole 42 is provided above the upper surface of the chemical | medical agent 2 accommodated in the cover part 4. FIG.

The size of the lid 4 is set so that a gap A is provided between the outer peripheral surface of the medicine 2 stored in the storage space 40 and the inner surface of the peripheral wall 41. Thereby, since the outer peripheral surface of the medicine 2 is exposed in the lid portion 4, the medicine is volatilized not only from the upper surface of the medicine 2 but also from the outer peripheral surface, and the volatilized medicine passes between the inner surface of the peripheral wall 41 of the lid portion 4. It is discharged to the outside through the volatilization hole 42. In the present embodiment, the peripheral wall 41 of the lid portion 4 is formed in a tapered shape that extends downward, and is inclined inward with respect to the vertical plane V at a predetermined inclination angle θ ₁ . The inclination angle theta ₁ of the peripheral wall 41 of the lid 4, have been set to be smaller than the inclination angle theta ₂ of the outer peripheral surface of the drug 2, inclined toward the inclined outer peripheral surface of the drug 2 of the peripheral wall 41 of the lid 4 It is steeper than. Thereby, the outer peripheral surface of the medicine 2 is separated from the inner surface of the peripheral wall 41 of the lid 4 as it goes upward, and the gap A between the outer peripheral surface of the medicine 2 and the inner surface of the peripheral wall 41 of the lid 4 is upward. It is formed so as to spread. Therefore, the medicine volatilized from the outer peripheral surface of the medicine 2 is smoothly guided through the gap A that spreads upward to the volatilization hole 42, and the volatilized medicine is smoothly discharged to the outside. The inclination angle θ ₂ of the outer peripheral surface of the medicine 2 is preferably 4 degrees or more.

  Thus, in the chemical volatilization container 1 of this embodiment, since the outer peripheral surface of the chemical | medical agent 2 is exposed in the cover part 4, as a result of the volatilization area of the chemical | medical agent 2 expanding, the volatilization efficiency of the chemical | medical agent 2 improves. Therefore, as a result of being able to release a sufficient amount of the volatilizing drug to the outside from the volatilization hole 42, the medicinal effect of the drug 2 can be effectively exhibited.

In addition, the planar view shape of the cover part 4 does not necessarily need to be circular, and may be polygonal. Moreover, the peripheral wall 41 of the cover part 4 does not necessarily need to be formed in a taper shape, and may be formed in a columnar shape extending straight and vertically. When the peripheral wall 41 of the lid part 4 is columnar, the inclination angle θ ₁ of the peripheral wall 41 of the lid part 4 is 0 degree, and if the outer peripheral surface of the medicine 2 is formed in a taper shape, The inclination angle θ ₂ is larger than the inclination angle θ ₁ of the peripheral wall 41 of the lid portion 4. The material of the lid 4 having the above-described configuration is not particularly limited, but is preferably made of paper (paper cup) or thin plastic (clear cup) from the viewpoint of being easily disposable.

On the other hand, the overall shape of the medicine 2 does not necessarily need to be a substantially truncated cone shape (or a truncated cone shape). Or the like. Moreover, (the outer peripheral surface of the upper portion protruding from the annular wall 35 in this embodiment) outer peripheral surface of the drug 2 does not need to tilt angle theta ₂ is no linear taper shape having a constant outer shape mountain shape like A parabolic taper shape in which the inclination angle θ is not constant may be used. Further, the outer peripheral surface of the medicine 2 and the inner surface of the peripheral wall 41 of the lid portion 4 are separated from each other upward, and the gap A between the outer peripheral surface of the medicine 2 and the inner surface of the peripheral wall 41 of the lid portion 4 is increased. If it becomes a shape, the whole shape of the medicine 2 can be various shapes such as a hemispherical shape and a staircase shape in addition to a shape in which the outer peripheral surface is tapered. Further, if the gap 2 is formed between the inner surface of the peripheral wall 41 of the lid portion 4 and the medicine 2, the outer peripheral surface has a columnar shape such as a columnar shape or a prismatic shape that extends straight from the peripheral edge of the bottom surface of the medicine 2. It may be formed.

  As shown in FIGS. 1, 2, and 4 to 11, the pedestal portion 3 is made of synthetic resin and is formed in a circular shape in plan view, and includes a bottom wall portion 30 and a peripheral edge of the bottom wall portion 30. And an annular peripheral wall portion 31 that rises from the top. A female screw portion 32 that is screwed with a male screw portion 52 of the ring-shaped member 5 described later is provided on the upper part of the inner surface of the peripheral wall portion 31 (see FIG. 1). The male screw portion 52 and the female screw portion 32 constitute an engaging portion 6 that engages the peripheral edge of the pedestal portion 3 with the ring-shaped member 5. The lower end portion of the peripheral wall portion 31 protrudes downward from the lower surface of the pedestal portion 3.

  At the center of the bottom wall portion 30, a holding column 33 is provided for fitting in the medicine 2 placed on the bottom wall portion 30 and holding the medicine 2 on the bottom wall portion 30. In this embodiment, the holding column 33 is composed of a plurality (four in the illustrated example) of plate-like holding plates 33A protruding from the upper surface of the bottom wall portion 30, and each holding plate 33A is centered on the center position of the bottom wall portion 30. The medicine 2 is restricted from rotating in the circumferential direction by extending radially. In addition, a disc-shaped scissors member 34 is detachably provided on the upper portion of the holding column 33, and the scissors member 34 is restricted from moving in the vertical direction.

  As shown in FIGS. 12 to 17, the eaves member 34 includes a disk portion 34 </ b> A, a concave portion 34 </ b> B having a circular opening in the center and protruding from the lower surface of the disk portion 34 </ b> A, and a concave portion provided at the periphery of the opening. And a cylindrical portion 34C protruding from the upper surface of 34B. A locking piece 33C is provided on the upper portion of each holding plate 33A by forming a U-shaped groove 33B. The upper portion of each holding plate 33A is fitted into the eave member 34 from the opening, and the concave portion 34B and the cylindrical portion 34C are fitted into the U-shaped groove 33B of each holding plate 33A so that the locking piece 33C is attached to the cylindrical portion 34C. The hook member 34 is attached to the holding column 33 by being locked to the upper end. Further, since this engagement is performed based on the elastic deformation of each holding plate 33A of the holding column 33, the hook member 34 can be removed by pulling the hook member 34 to release the engagement with each holding plate 33A. it can.

  Returning to FIGS. 1, 2, and 4 to 11, the upper surface of the bottom wall portion 30 has an inner diameter substantially the same as the diameter of the lower portion of the medicine 2 to be placed, and surrounds the lower portion of the medicine 2. An annular wall 35 is provided so as to protrude from the upper surface of the bottom wall portion 30. In addition, an annular weir portion 36 that is lower than the annular wall 35 and faces the inner wall surface of the lid portion 4 placed on the bottom wall portion 30 is provided around the annular wall 35. It is provided so as to protrude from the upper surface of. Further, an annular contact ring 37 having a lower height than the dam portion 36 is provided around the dam portion 36 so as to protrude from the upper surface of the bottom wall portion 30.

  The weir portion 36 has an outer diameter slightly smaller than the diameter of the lower end opening of the lid portion 4, and when the lid portion 4 is placed on the bottom wall portion 30 as will be described later, the lid portion 4. It functions as a positioning to position at the optimal position. As will be described later, when the lid 4 is fixed to the pedestal 3 by the engagement of the ring-shaped member 5 and the pedestal 3 with the lid 4 placed on the bottom wall 30, the lid If the portion 4 is made of a soft material such as paper or thin plastic, the lower portion of the peripheral wall 41 of the lid portion 4 may be pushed inward by tightening the ring-shaped member 5. At this time, the shape of the peripheral wall 41 of the cover part 4 can be maintained by preventing the lower part of the peripheral wall 41 of the cover part 4 from being pushed inward by the dam part 36 functioning as a stopper. Further, at this time, the inner wall surface of the lid portion 4 comes into contact with the outer peripheral surface of the dam portion 36, so that the inside of the storage space 40 of the lid portion 4 can be sealed well.

  The contact ring 37 is provided at a position facing the flange portion 45 of the lid portion 4 placed on the bottom wall portion 30, and when the lid portion 4 is placed on the bottom wall portion 30, the flange portion The lower surface of 45 abuts on the upper surface of the contact ring 37. As will be described later, the ring-shaped member 5 includes an annular portion 50 that faces the flange portion 45 of the lid portion 4 when engaged with the pedestal portion 3 (see FIG. 1), and the contact ring of the pedestal portion 3. 37 and the annular portion 50 of the ring-shaped member 5 sandwich the flange portion 45 from above and below, so that the lid portion 4 is securely fixed to the pedestal portion 3. Thereby, even when the chemical volatilization container 1 falls down at the time of use or before use, it is prevented that fixation of the base part 3 and the cover part 4 comes off. Further, since the flange portion 45 is sandwiched between the contact ring 37 of the pedestal portion 3 and the annular portion 50 of the ring-shaped member 5, the inside of the storage space 40 of the lid portion 4 can be satisfactorily sealed.

  The pedestal portion 3 is provided with a communication portion 38 that communicates the inside and outside of the storage space 40 of the lid portion 4. When the inside of the storage space 40 of the lid part 4 is completely sealed, oxygen in the storage space 40 is consumed before the chemical volatilization container 1 is used, so that the inside of the storage space 40 is depressurized. There arises a problem that a part of the peripheral wall 41 of the portion 4 is recessed. In the present embodiment, since the air inside and outside the storage space 40 of the lid 4 can be circulated through the communication portion 38, the inside of the storage space 40 is prevented from being depressurized before the chemical volatilization container 1 is used. As a result, the peripheral wall 41 of the lid 4 can be prevented from being recessed. Therefore, since it can prevent that the chemical | medical agent volatilization container 1 before use deteriorates, the chemical volatilization container 1 will be disposed of in the unused state where the chemical | medical agent 2 still remains in the cover part 4. Can be prevented.

  In the present embodiment, the first groove portion 38A extending in the vertical direction from the upper end to the lower end is formed on the outer peripheral surface of the dam portion 36, and is continuous with the first groove portion 38A on the upper surface of the bottom wall portion 30. A second groove 38 </ b> B extending through the contact ring 37 in the radial direction on the upper surface of the portion 30 to the annular wall 31 outside the lid portion 4 is formed. The first groove portion 38A forms a gap between the outer peripheral surface of the dam portion 36 and the inner wall surface of the lid portion 4, and the second groove portion 38B is formed on the upper surface (contact ring 37) of the bottom wall portion 30 and the lid portion. A gap is formed between the first and second flange portions 45, and the first and second groove portions 38A and 38B communicate the inside and outside of the storage space 40 of the lid portion 4.

  The size and number of the communication portions 38 are not particularly limited, and a plurality of communication portions 38 may be provided on the pedestal portion 3. Moreover, the shape of the communication part 38 does not need to be a groove part like this embodiment. For example, by forming a through hole in the contact ring 37 instead of the second groove 38B, the inside and outside of the storage space 40 of the lid 4 can be communicated with each other by the through hole and the first groove 38A. Further, when the dam portion 36 is not provided on the upper surface of the bottom wall portion 30 or when the outer peripheral surface of the dam portion 36 and the inner wall surface of the lid portion 4 are not necessarily in contact with each other, it is necessary to provide the first groove portion 38A. In addition, the inside and outside of the storage space 40 of the lid portion 4 can be communicated with each other only by the through hole formed in the second groove portion 38B or the contact ring 37.

  One or a plurality of water storage grooves 39 are formed around the medicine 2 on the upper surface of the bottom wall portion 30 of the pedestal portion 3. In the present embodiment, a plurality of water storage grooves 39 are juxtaposed at predetermined intervals along the circumferential direction between the contact ring 37 and the weir part 36, and each water storage groove 39 has a lower end of the weir part 36. The upper surface of the bottom wall portion 30 extends radially before the contact ring 37. The water storage groove 39 is for storing the water emitted from the medicine 2. In the case where the drug 2 is in a gel form, part of the water retained by the gel drug 2 is discharged over time. The discharged water adheres to the inner wall surface of the lid portion 4 and flows down the inner wall surface, and then is dispersed inside and outside the weir portion 36. However, a part of the moisture dispersed outside the weir portion 36 is It is discharged onto the bottom wall portion 30 between the contact ring 37 via a plurality of vertical grooves 36A formed on the outer peripheral surface of the portion 36. At this time, in the present embodiment, since the water storage grooves 39 are formed on the upper surface of the bottom wall portion 30 so as to correspond to the vertical grooves 36 </ b> A, the discharged water is stored in the water storage grooves 39. Thereby, since the discharged | emitted water | moisture content is prevented from seeping out beyond the contact ring 37, it can prevent that a water | moisture content leaks to the outer side of the chemical volatilization container 1. FIG. The shape, size, and number of the water storage grooves 39 are not particularly limited, and can be set to various shapes, sizes, and numbers.

  The lower surface of the pedestal portion 3 has at least one groove 60 (for example, 3) that penetrates deeply in the rotation direction in which the pedestal portion 3 and the ring-shaped member 5 are engaged by screwing the male screw portion 52 and the female screw portion 32. One) is provided. The groove 60 having such a configuration includes an inclined surface 61 that is deeply inclined in the rotational direction in which the pedestal 3 and the ring-shaped member 5 are engaged, and a vertical surface 62 that is positioned at the tip of the inclined surface 61. When the pedestal part 3 is rotated with respect to the ring-shaped member 5 and both are engaged, if the fingernail or the like is hooked on the vertical surface 62 of the pedestal part 3 to rotate the pedestal part 3, It can be easily engaged. On the other hand, when the pedestal portion 3 is rotated relative to the ring-shaped member 5 in the direction opposite to the above in order to disengage the both, a fingernail or the like may be hooked on the inclined surface 61 of the pedestal portion 3. Since the claw or the like cannot slide on the inclined surface 61 and rotate the pedestal portion 3, it is difficult to disengage the two. Thus, in this embodiment, the ring-shaped member 5 is prevented from being easily removed from the pedestal portion 3.

  Next, as shown in FIGS. 1, 2, and 18 to 24, the ring-shaped member 5 is made of a synthetic resin and is formed in a circular shape in a plan view. An annular surrounding portion 51 is provided so as to surround the annular portion 50 and is provided integrally with the annular portion 50. On the outer peripheral surface of the annular portion 50, a male screw portion 52 that is screwed with the female screw portion 32 provided on the inner peripheral surface of the pedestal portion 3 (peripheral wall portion 31) is provided. At the time of engagement with the member 5, the peripheral wall portion 31 of the pedestal portion 3 is located between the annular portion 50 and the surrounding portion 51 of the ring-shaped member 5. A plurality of ribs 53 extending in the vertical direction are provided on the lower inner peripheral surface of the annular portion 50 at a predetermined interval in the circumferential direction, thereby reinforcing the lower portion of the annular portion 50. The annular portion 50 faces the flange portion 45 of the lid portion 4 when the ring-shaped member 5 and the pedestal portion 3 are engaged, and sandwiches the flange portion 45 from above and below with the contact ring 37 of the pedestal portion 3.

  The surrounding portion 51 is a cosmetic cover that covers the peripheral wall portion 31 of the pedestal portion 3 when the pedestal portion 3 and the ring-shaped member 5 are engaged, and the user turns the peripheral wall portion 31 of the pedestal portion 3 to form a ring shape. Direct contact with the peripheral wall portion 31 is prevented so that the engagement between the member 5 and the pedestal portion 3 is not accidentally released. The lower end portion of the surrounding portion 51 extends longer than the lower end portion of the annular portion 50, and more than the lower end portion of the peripheral wall portion 31 of the pedestal portion 3 when the pedestal portion 3 and the ring-shaped member 5 are engaged. The length is set so as to be positioned above. Thereby, since the lower end part of the peripheral wall part 31 of the base part 3 protrudes below the lower end part of the surrounding part 51 of the ring-shaped member 5 at the time of engagement with the base part 3 and the ring-shaped member 5, for example, the chemical volatilization container 1 Is accidentally dropped onto a table or the like, the pedestal 3 receives an impact mainly from the table or the like. Here, when the lower end portion of the surrounding portion 51 of the ring-shaped member 5 protrudes below the lower end portion of the peripheral wall portion 31 of the pedestal portion 3, the ring-shaped member 5 receives an impact mainly from the table or the like when dropped. Then, an upward force that disengages from the pedestal portion 3 acts on the ring-shaped member 5, and therefore, if the degree of impact is large, the ring-shaped member 5 may be detached from the pedestal portion 3 due to the impact at the time of dropping. However, in the present embodiment in which the surrounding portion 51 is located above the lower end portion of the peripheral wall portion 31, the ring-shaped member 5 is removed from the pedestal portion 3 by causing the impact at the time of dropping to mainly act on the pedestal portion 3. It prevents it from coming off.

Next, the manufacturing method of the chemical volatilization container 1 of the said structure is demonstrated with reference to FIG. First, as shown in FIG. 25A, the cover member 7 is placed on the pedestal portion 3. The cover member 7 is made of plastic, for example, and has a circular cup shape in plan view with a filling port 71 at the center of the upper end surface and the entire lower end surface opened as shown in FIG. The lower end opening 72 is placed on the bottom and the filling port 71 is placed on the pedestal 3. The size of the cover member 7 is set so that the outer shape in plan view is smaller than the outer shape of the lid portion 4 and the height and the upper end surface thereof are located below the volatilization hole 42 of the lid portion 4. . The peripheral wall 70 of the cover member 7 includes a cylindrical base portion 70A and a tapered portion 70B that is integrally provided on the base portion 70A and has a linear taper shape whose outer peripheral surface extends downward. The base portion 70 </ b> A of the peripheral wall 70 has an inner diameter slightly larger than the outer diameter of the annular wall 35 on the pedestal portion 3, and the height is set to be substantially the same as the height of the annular wall 35. In the present embodiment, the cover member 7 is disposed around the annular wall 35 on the pedestal portion 3 so that the annular wall 35 fits within the base portion 70 </ b> A of the peripheral wall 70, so the annular wall 35 is placed on the pedestal portion 3. It functions as positioning when the cover member 7 is placed. Therefore, the cover member 7 can be easily arranged at an optimal position by the annular wall 35. The tapered portion 70B of the peripheral wall 70 is inclined inward with respect to the vertical plane V at a predetermined inclination angle θ ₂ and is set to be larger than the inclination angle θ ₁ of the peripheral wall 41 of the lid portion 4. .

Next, as shown in FIG. 25 (b), a sol containing a drug component, a gelling agent, a volatile substance, or the like as a raw material of the drug 2 is filled in the cover member 7 from the filling port 71 on the upper end surface of the cover member 7. After that, the drug 2 is formed by gelling (solidifying or semi-solidifying) the sol in the cover member 7 by cooling or the like (FIG. 25 (c)). At this time, the medicine 2 is molded into a shape corresponding to the shape of the cover member 7. Therefore, the medicine 2 is formed in a substantially truncated cone shape having a columnar lower portion and a truncated cone-shaped upper portion, and the outer peripheral surface of the medicine 2 (in this embodiment, the outer peripheral surface of the upper portion protruding from the annular wall 35). the inclination angle theta ₂ of the the same as the inclination angle theta ₂ of the peripheral wall 70 of the cover member 7 is larger than the inclination angle theta ₁ of the peripheral wall 41 of the lid 4.

  Then, the cover member 7 is removed from the medicine 2, and the lid 4 is placed on the pedestal portion 3 to store the medicine 2 in the storage space 40. At this time, since the dam portion 36 is provided on the pedestal portion 3, the lid portion 4 is arranged on the pedestal portion 3 so that the inner surface of the peripheral wall 41 of the lid portion 4 faces the dam portion 36. The lid portion 4 can be easily arranged at an optimal position. And the chemical volatilization container 1 is manufactured by fixing the cover part 4 to the base part 3 (FIG.25 (d)). The lid 4 and the pedestal 3 are fixed by covering the ring-shaped member 5 from above with respect to the pedestal 3 covering the lower end opening of the lid 4 and engaging the ring-shaped member 5 and the periphery of the pedestal 3. By doing. At this time, since the flange portion 45 of the lid portion 4 is sandwiched between the upper surface of the pedestal portion 3 and the ring-shaped member 5, the lid portion 4 is securely fixed on the pedestal portion 3.

In the medicine volatilization container 1 manufactured in this way, the medicine 2 accommodated in the lid 4 is molded in the cover member 7 and then covered with the lid 4 having a larger outer shape than the cover member 7. Therefore, a gap A is formed between the outer peripheral surface of the medicine 2 and the inner surface of the peripheral wall 41 of the lid 4. The inclination angle theta ₂ of the outer peripheral surface of the drug 2 (the outer peripheral surface of the upper portion protruding from the annular wall 35 in this embodiment) is the same as the inclination angle theta ₂ of the peripheral wall 70 of the cover member 7 (the tapered portion 70B) Since the inclination angle θ ₁ of the peripheral wall 41 of the lid part 4 is larger than the inclination angle θ _{1, the} gap A formed between the outer peripheral surface of the medicine 2 and the inner surface of the peripheral wall 41 of the lid part 4 expands upward as it goes upward. It becomes a shape.

  In addition, the cover member 7 used for molding of the medicine 2 does not necessarily have a circular shape in plan view, and may have a polygonal shape. Moreover, the taper part 70B of the peripheral wall 70 of the cover member 7 does not necessarily need to be a linear taper shape, and may be a parabolic taper shape. Further, the entire peripheral wall 70 of the cover member 7 including the base portion 70A may be tapered. Moreover, if it separates from the inner surface of the peripheral wall 41 of the cover part 4 as it goes upwards, according to the whole shape of the chemical | medical agent 2 to shape | mold, in addition to the shape where an outer peripheral surface becomes a taper shape, step shape Cover members having various shapes such as shapes can be used. Moreover, if the clearance gap A is formed between the inner surfaces of the peripheral wall 41 of the cover part 4, you may use the column-shaped cover member which the surrounding wall 70 extends perpendicularly | vertically, such as a column shape and a prism shape. Further, the material of the cover member 7 may be made of paper instead of plastic. Moreover, the inner surface of the cover member 7 may improve the releasability with the medicine 2 after molding by applying a release agent or the like.

  The above-described drug volatilization container 1 has the drug 2 sealed in the lid 4 before use, while in use, the perforation 44 is broken and the cover member 43 is opened to form the volatilization hole 42. From each volatilization hole 42, the volatilization chemical volatilized from the chemical 2 is released to the outside. At this time, by appropriately selecting the number of volatilization holes 42 to be formed, the volatilization amount and odor intensity of the medicine 2 released to the outside can be adjusted. Moreover, since the chemical | medical agent 2 is located below the volatilization hole 42 in the cover part 4, and the chemical | medical agent 2 is prevented from touching directly with a hand, safety | security with respect to an infant etc. is high.

  According to the medicine volatilization container 1 described above, since the gap A is provided between the outer peripheral surface of the medicine 2 accommodated in the lid portion 4 and the inner surface of the peripheral wall 41 of the lid portion 4, the medicine 2 is not only the upper surface. The outer peripheral surface is also exposed in the lid 4. Therefore, the volatilization area of the drug 2 is expanded and the volatilization efficiency of the drug 2 is improved. As a result, a sufficient amount of the volatilization drug can be released to the outside from the volatilization hole 42 and the medicinal effect of the drug 2 is effectively exhibited. be able to.

  Moreover, the outer peripheral surface of the medicine 2 is separated from the inner surface of the peripheral wall 41 of the lid 4 as it goes upward, and the gap A between the outer peripheral surface of the medicine 2 and the inner surface of the peripheral wall 41 of the lid 4 is upward. By being formed so as to expand, the drug volatilized from the outer peripheral surface of the drug 2 is smoothly guided through the gap A to the volatilization hole 42. Therefore, it is possible to smoothly release the volatilized drug to the outside.
