It is attached to the drug container 2 to make it difficult to do. A plurality of volatilization holes 53 are formed in the cover 5, and when the cover 5 is attached to the drug container 2, the drug component of the drug solution volatilized from the liquid absorbing core material 3 passes through the respective volatilization holes 53 of the cover 5. And it is released to the external space.

Hereinafter, after explaining the chemical solution, each component of the chemical volatilizer 1 will be described in detail.

Chemical solution (liquid drug)
The chemical solution has volatilization property (sustained release property), and exerts a medicinal effect by gradually volatilizing the drug component into the air by contact with air. The drug solution contains a drug component. Examples of the drug component include an fragrance component, a deodorant component, an insecticide component, an insect repellent component, a repellent component, an antibacterial agent component, and the like. The drug solution may contain one of these drug components alone, or may contain a plurality of them in combination. The drug component may be either oily or aqueous as long as it can be volatilized.

The viscosity of the chemical solution is not particularly limited, but is preferably 0.1 mPa · s or more and 30 mPa · s or less, more preferably 0.1 mPa · s or more and 20 mPa · s or less, and 0. It is more preferable that it is 1 mPa · s or more and 10 mPa · s or less. The viscosity of the chemical solution can be measured in an environment of 25 ° C. using a vibration viscometer (VM-3OO-L manufactured by Sekonic).

Drug container As shown in FIGS. 2 to 4, the drug container 2 has a mouth portion 20 having both upper and lower ends open, and the liquid absorbing core material 3 is inserted into the drug container 2 from the mouth portion 20. Further, the liquid absorbing core material 3 is held in the mouth portion 20 to prevent it from coming out of the drug container 2. The drug container 2 is preferably composed of a container body 6 and a tubular inner plug 7 having both upper and lower ends open to and from the container body 6.

The container body 6 includes a hollow and bottomed body 60 and a tubular body 61 integrally formed with the body 60 and having both upper and lower ends open. The container body 60 is preferably transparent or translucent in part or in whole, whereby the remaining amount of the chemical solution can be confirmed from the outside. The material of the container body 60 is not particularly limited, and examples thereof include synthetic resin and glass.

The body 60 includes a bottom portion 62, a peripheral wall portion 63 rising from the outer peripheral edge of the bottom portion 62, and a shoulder portion 64 connected to the upper end of the peripheral wall portion 63 so as to face the bottom portion 62. The internal space of the body 60 is the storage space 21 for the chemical solution. The shoulder portion 64 has a rectangular shape in a plan view, and a tubular body 61 is connected to the center of the shoulder portion 64 so as to extend upward.

The bottom portion 62 is not particularly limited, but exhibits a rectangular shape in a plan view. The bottom portion 62 preferably has a central portion raised from the outer peripheral edge portion, whereby the drug container 2 can be stably placed on a horizontal table.

As shown in FIG. 5, a liquid pool portion 65 is provided on the inner bottom surface of the bottom portion 62. The liquid pool portion 65 is formed by denting a part of the inner bottom surface of the bottom portion 62 in a concave shape. The liquid pool portion 65 is not particularly limited, but has a circular shape in a plan view, and is preferably located at the center of the bottom portion 62.

When the liquid pool portion 65 is provided on the inner bottom surface of the bottom portion 62, the remaining amount of the chemical solution in the drug container 2 is reduced and the liquid level becomes near the inner bottom surface of the bottom portion 62, the chemical solution is liquid due to surface tension. It is pulled toward the pool portion 65 and gathers in the liquid pool portion 65. Since the lower end portion of the liquid absorbing core material 3 is located directly above the liquid collecting portion 65, the chemical liquid collected in the liquid collecting portion 65 can be sucked up by the lower end portion of the liquid absorbing core material 3. As described above, even if the remaining amount of the chemical solution in the drug container 2 is reduced due to the presence of the liquid pool portion 65, the drug solution can be satisfactorily sucked up by the liquid absorbing core material 3 and the drug component can be volatilized in the external space.

The liquid pool portion 65 preferably has an outer diameter m smaller than the outer diameter L at least at the lower end of the liquid absorbing core material 3 and has a size of being covered from above by the liquid absorbing core material 3. The outer diameter m of the liquid pool portion 65 refers to the outer diameter of the opening edge opened at the inner bottom surface of the bottom portion 62 of the liquid pool portion 65 (the outer diameter at the height of the inner bottom surface of the liquid pool portion 65). As a result, the lower end surface of the liquid absorbing core material 3 faces the liquid collecting portion 65 as a whole. As will be described later, depending on the specifications of the liquid absorbing core material 3, it may be difficult to suck up the chemical solution from the outer peripheral surface of the liquid absorbing core material 3, for example, the liquid absorbing core material 3 is subjected to a treatment for improving the strength of the outer peripheral surface. In this case, it is necessary to suck up more chemical solution from the lower end surface of the liquid absorbing core material 3. Since the liquid collecting portion 65 is covered with the liquid absorbing core material 3 from above, the chemical liquid collected in the liquid collecting portion 65 can be efficiently sucked up from the lower end surface of the liquid absorbing core material 3. Therefore, even if the liquid-absorbent core material 3 has the above-mentioned specifications, the liquid-absorbent core material 3 can suck up all the chemicals in the drug container 2 as much as possible and use up the chemicals to the end.

As shown in FIGS. 2 to 4, the shoulder portion 64 is not particularly limited, but is one size smaller than the peripheral wall portion 63 and has a stepped portion 66 between the shoulder portion 64 and the peripheral wall portion 63. A plurality of (four in this embodiment) recesses that can be hooked and fastened to a plurality of (four in this embodiment) engaging protrusions 52 (shown in FIG. 7) of the cover 5 described later in the step portion 66. 67 are formed at equal intervals in the circumferential direction. By engaging the plurality of engaging protrusions 52 of the cover 5 with the plurality of recesses 67 of the step portion 66, the cover 5 can be attached to the drug container 2 and both can be connected so that the cover 5 does not easily come off from the drug container 2. Is.

The tubular body 61 is not particularly limited, but has a cylindrical shape, and the cross-sectional view shape of the inner wall surface and the outer wall surface is circular. In the present disclosure, the cross-sectional view shape is a shape of a cross section along the horizontal direction. The tubular body 61 is preferably located directly above the liquid pool portion 65 in the center of the bottom portion 61, and the center of the tubular body 61 and the center of the bottom portion 62 are in the same linear shape. A male screw 68 is provided on the outer peripheral surface of the tubular body 61. The male screw 68 is screwed with the female screw 42 (shown in FIG. 6) of the cap 4 described later, whereby the cap 4 is attached to the mouth portion 20 of the drug container 2 so that the cap 4 does not easily come off from the mouth portion 20. Can be connected. The means for attaching the cap 4 to the mouth 20 of the drug container 2 and connecting the two is not particularly limited, and various other known means can be used.

The inner plug 7 can be attached to and detached from the cylinder 61 of the container body 6. The mouth portion 20 of the drug container 2 is formed by the tubular body 61 and the inner plug 7, and the liquid absorbing core material 3 is inserted into the inner plug 7. The inner plug 7 is not particularly limited, but has a cylindrical shape, and the cross-sectional view of the inner wall surface and the outer wall surface is circular. The inner plug 7 is formed to have an outer diameter that can be fitted inside the cylinder 60, and the inner plug 7 is held inside the cylinder 60.

The inner plug 7 is not particularly limited, but has a fitting portion 70 on the upper side in the height direction in which the outer wall surface abuts on the inner wall surface of the cylinder 61 and is fitted into the cylinder 61, and an inner diameter slightly larger than that of the fitting portion 70. It also includes a holding portion 71 on the lower side in the height direction having a small outer diameter, and a tapered portion 72 connecting the fitting portion 70 and the holding portion 71.

The fitting portion 70 has an inner diameter larger than the outer diameter L of the liquid absorbing core material 3, and the inner wall surface of the fitting portion 70 does not come into contact with the outer peripheral surface of the liquid absorbing core material 3 inserted into the inner plug 7, and the liquid absorbing core material A gap is formed between the three and the third. A flange portion 73 horizontally protrudes outward from the upper end of the fitting portion 70. When attaching the inner plug 7 to the cylinder 61 of the container body 6, the inner plug 7 is inserted into the cylinder 61 until the flange portion 73 abuts on the upper end of the cylinder 61.

The inner diameter l of the sandwiching portion 71 is smaller than the outer diameter L of the liquid absorbing core material 3, that is, the cross-sectional view shape of the inner wall surface is smaller than the cross-sectional view shape of the liquid absorbing core material 3. Therefore, the inner wall surface of the holding portion 71 presses the outer peripheral surface of the liquid absorbing core material 3 inserted into the inner plug 7. When the liquid-absorbent core material 3 is inserted into the holding portion 71 while being pushed in, the liquid-absorbent core material 3 is deformed so as to shrink in diameter (the outer peripheral surface is constricted) as shown in FIG. In the portion sandwiched by the sandwiching portion 71), the outer peripheral surface abuts on the inner wall surface of the sandwiching portion 71 and is sandwiched by the sandwiching portion 71. As a result, the liquid absorbing core material 3 is attached to the mouth portion 20 of the drug container 2 and is held in the drug container 2 without easily coming out of the mouth portion 20.

The inner and outer diameters of the tapered portion 72 gradually decrease toward the bottom. When the liquid-absorbent core material 3 is inserted into the inner plug 7, the liquid-absorbent core material 3 is gradually deformed by the tapered portion 72 so as to reach the sandwiching portion 71, so that the liquid-absorbing core material 3 is inserted into the sandwiching portion 71. It can be inserted smoothly inside.

The material of the inner plug 7 is not particularly limited, but for example, polyethylene terephthalate or the like can be mentioned more specifically than the synthetic resin.

Liquid- absorbent core material The liquid-absorbent core material 3 is a rod-shaped member that extends linearly before being inserted into the drug container 2, and is not particularly limited, but exhibits a columnar shape having a circular cross-sectional view. Further, the liquid absorbing core material 3 is not particularly limited, but exhibits a circular shape having substantially the same outer diameter L in cross-sectional view over the entire length and the thickness is substantially the same over the entire length. The liquid absorbing core material 3 is inserted into the drug container 2 from the mouth portion 20 and used. The length of the liquid absorbing core material 3 is such that the lower end reaches the inner bottom surface of the drug container 2 and a part of the upper end side can protrude upward from the mouth portion 20 of the drug container 2. Since the lower end of the liquid-absorbing core material 3 reaches the inner bottom surface of the drug container 2, the drug solution can be sucked up by the liquid-absorbing core material 3 even if the remaining amount of the drug solution in the drug container 2 is low.

The material of the liquid-absorbing core material 3 is not particularly limited as long as the chemical solution in the drug container 2 can be sucked up by the capillary phenomenon and the sucked-up drug solution can be volatilized in the external space. For example, various materials such as nylon, polyester (for example, polyethylene terephthalate), polypropylene, polyethylene, polyoxymethylene, isoparaffin, cellulose, rattan, and pulp can be mentioned as the material of the liquid absorbing core material 3, and these materials are one kind. It may be used alone or in combination of two or more. Further, although not particularly limited, for the purpose of suppressing deformation of the liquid absorbing core material 3 at high temperatures and maintaining a stable shape of the liquid absorbing core material 3, other suitable materials may be used as the liquid absorbing core material. It may be further used as the material of 3.

As the liquid-absorbing core material 3, for example, in order to satisfactorily suck up the chemical solution, for example, a material obtained by welding or adhering a fibrous material to form a rod, a material obtained by knitting a fibrous material into a rod, or a fibrous material was used. A non-woven fabric in the shape of a rod or a sponge in the shape of a rod can be used.

The liquid absorbing core material 3 is not particularly limited, but may be treated, for example, to improve the strength of the outer peripheral surface. As a result, even if the user holds the liquid absorbing core material 3 by hand and the outer peripheral surface is rubbed many times when the liquid absorbing core material 3 is inserted into the drug container 2, the liquid absorbing core material 3 can be fluffed and absorbed. It is possible to prevent the liquid core material 3 from being damaged.

As shown in FIG. 4, when the liquid absorbing core material 3 is inserted into the drug container 2, the outer diameter L of the liquid absorbing core material 3 is longer than the inner diameter l of the holding portion 71 of the mouth portion 20. A part in the wedge direction is sandwiched by the sandwiching portion 71, and the portion sandwiched by the sandwiching portion 71 is deformed so as to have a reduced diameter. In this way, the liquid-absorbing core material 3 inserted into the drug container 2 is tightened by the holding portion 71 of the mouth portion 20, so that the capillaries of the liquid-absorbing core material 3 become thin, and the function of sucking up the chemical liquid by the capillary phenomenon is performed. Be promoted. As a result, the amount of the chemical liquid sucked up by the liquid absorbing core material 3 increases, and it is difficult for the liquid absorbing core material 3 to suck up the chemical liquid from the outer peripheral surface by performing a treatment for improving the strength of the outer peripheral surface of the liquid absorbing core material 3, for example. Even when the specifications are specified, the liquid absorbing core material 3 can suck up a sufficient amount of the chemical liquid from the lower end surface and satisfactorily volatilize the chemical components into the external space.

The outer diameter L of the liquid absorbing core material 3 is not particularly limited, but from the viewpoint of effectively promoting the function of sucking up the chemical liquid due to the capillary phenomenon by tightening by the mouth portion 20 of the above-mentioned drug container 2, the holding portion 71 The inner diameter l is preferably 1.05 times or more, and more preferably 1.1 times or more. Further, although it depends on the ease of deformation of the liquid absorbing core material 3, the outer diameter L of the liquid absorbing core material 3 is the holding portion from the viewpoint of allowing the liquid absorbing core material 3 to pass through the holding portion 71 without difficulty. The inner diameter l of 71 is preferably 1.5 times or less, and more preferably 1.2 times or less.

The length of the portion of the liquid absorbing core material 3 that is sandwiched by the sandwiching portion 71, that is, the height of the sandwiching portion 71 is not particularly limited, but the drug solution due to the capillary phenomenon due to the tightening by the mouth portion 20 of the drug container 2 described above is not particularly limited. From the viewpoint of effectively promoting the suction function, it is preferably 1/5 or more and 4/5 or less of the total length of the liquid absorbing core material 3, and more preferably 2/5 or more and 3/5 or less.

The

cap

cap 4 is for sealing a part of the liquid absorbing core material 3 exposed above the drug container 2 when the drug volatilizer 1 is not used. The cap 4 is not particularly limited, but is made of synthetic resin, and as shown in FIGS. 2 and 6, the cap 4 has a cylindrical covering portion 40 having a closed upper end and an open lower end, and an outer diameter larger than that of the covering portion 40. It includes a large and centrally connected cylindrical mounting portion 41 such that the covering portion 40 extends upward.

The covering portion 40 has an inner diameter and a height capable of accommodating a portion of the liquid absorbing core material 3 exposed above the drug container 2 inside. The mounting portion 41 has an inner diameter that allows the mouth portion 20 of the drug container 2 to be fitted inward. On the inner peripheral surface of the mounting portion 41, a female screw 42 screwed with a male screw 68 provided on the outer peripheral surface of the mouth portion 20 of the drug container 2, specifically, the outer peripheral surface of the tubular body 61 is provided.

The

cover

cover 5 is for improving the aesthetic appearance of the drug volatilizer 1 when the drug volatilizer 1 is used. The cover 5 is not particularly limited, but is made of synthetic resin, and as shown in FIGS. 1, 2, and 7, a top surface portion 50 having a rectangular shape in a plan view and a peripheral surface portion 51 hanging from the outer peripheral edge of the top surface portion 50. And include.

The peripheral surface portion 51 can fit the shoulder portion 64 of the drug container 2 inward, and the shoulder portion 64 fits inside the peripheral surface portion 51. At the lower end of the inner surface of the peripheral surface portion 51, a plurality of engaging protrusions 52 protruding inward are provided at intervals in the circumferential direction. The plurality of engaging protrusions 52 engage with the recesses 67 of the stepped portion 66 of the drug container 2. On the top surface portion 50 and the peripheral surface portion 51 of the cover 5, a plurality of volatilization holes 53 for discharging the drug components of the drug solution that are sucked up and volatilized by the liquid absorbing core material 3 into the external space are formed.

Method of using the drug volatilizer Next, the method of using the drug volatilizer 1 of the present embodiment described above will be described. First, before the start of use, the cap 4 is attached to the mouth 20 of the drug container 2, and the liquid absorbing core material 3 is sealed. Therefore, at the start of use, the cap 4 is removed from the mouth 20 of the drug container 2 with the bottom 62 of the drug container 2 facing down and the cap 4 facing up. As a result, the liquid absorbing core material 3 is exposed, the chemical liquid in the drug container 2 is sucked up by the liquid absorbing core material 3, and the chemical components of the chemical liquid are continuously volatilized in the external space. As a result, the space in which the drug volatilizer 1 is installed can be made a comfortable space. While the drug volatilizer 1 is in use, the cover 5 can be attached to the drug container 2 as needed.

Actions and effects of the drug volatilizer The drug volatilizer 1 of the present embodiment described above is provided with a liquid pool portion 65 on the inner bottom surface of the bottom portion 62. Therefore, when the remaining amount of the chemical solution in the drug container 2 decreases and the liquid level becomes near the inner bottom surface of the bottom portion 62, the chemical solution is pulled toward the liquid pool portion 65 by the surface tension and the liquid pool portion Gather at 65. Since the lower end portion of the liquid absorbing core material 3 is located directly above the liquid collecting portion 65, the chemical liquid collected in the liquid collecting portion 65 can be sucked up by the lower end portion of the liquid absorbing core material 3. As described above, in the drug volatilizer 1 of the present embodiment, even if the remaining amount of the drug solution in the drug container 2 decreases due to the presence of the liquid pool portion 65, the liquid absorbing core material 3 satisfactorily sucks up the drug solution to the outside. The drug component can be volatilized in the space.

Further, according to the chemical volatilizer 1 of the present embodiment, the liquid pool portion 65 has an outer diameter smaller than the outer diameter of at least the lower end of the liquid absorbing core material 3, and is covered from above by the liquid absorbing core material 3. Therefore, the lower end surface of the liquid absorbing core material 3 faces the liquid collecting portion 65 as a whole. For example, depending on the specifications of the liquid absorbing core material 3, it may be difficult to suck up the chemical liquid from the outer peripheral surface of the liquid absorbing core material 3, such as processing to improve the strength of the outer peripheral surface of the liquid absorbing core material 3. Since the 65 is covered with the liquid absorbing core material 3 from above, the chemical liquid collected in the liquid collecting portion 65 can be efficiently sucked up from the lower end surface of the liquid absorbing core material 3. Therefore, even if the liquid absorbing core material 3 has a specification that it is difficult to suck up the chemical liquid from the outer peripheral surface, the liquid absorbing core material 3 can suck up all the chemical liquid in the drug container 2 as much as possible and use up the chemical liquid to the end.

Modifications of the Chemical Volatilizer Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

In the above-described embodiment, the cross-sectional view of the liquid absorbing core material 3 is circular, and the cross-sectional view of the inner wall surface of the holding portion 71 of the mouth portion 20 of the drug container 2 is circular. Since the outer diameter of the liquid absorbing core material 3 is larger than the inner diameter of the holding portion 71, the liquid absorbing core material 3 abuts on the inner wall surface of the holding portion 71 over the entire circumference of the outer peripheral surface of the holding portion 71. However, it is not necessary to bring the entire circumference of the outer peripheral surface of the liquid absorbing core material 3 into contact with the inner wall surface of the sandwiching portion 71. A slit is formed, and the inside and outside of the medicine container 2 are communicated with the storage space 21 of the medicine container 2 and the outside space without contacting the liquid absorbing core material 3 with the inner wall surface of the holding portion 71 at the portion where the slit is located. Air may be able to flow.

Further, in the above-described embodiment, the cross-sectional view of the liquid-absorbent core material 3 is circular, but as another modification, the cross-sectional view of the liquid-absorbent core material 3 is, for example, triangular or square. It may be a polygonal shape or various other shapes such as an elliptical shape. In this modification, as shown in FIG. 8, the cross-sectional view of the liquid-absorbing core material 3 is cross-sectionally formed by making the diameter of the inscribed circle S1 larger than the inner diameter of the sandwiching portion 71. When the visual shape is superimposed on the cross-sectional view shape of the inner wall surface of the sandwiching portion 71, a part of the cross-sectional view shape of the liquid absorbing core material 3 protrudes to the outside of the cross-sectional view shape of the inner wall surface of the sandwiching portion 71. Therefore, the cross-sectional view shape of the inner wall surface of the holding portion 71 can be made smaller than the cross-sectional view shape of the portion sandwiched by the holding portion 71 of the liquid absorbing core material 3, whereby the liquid absorbing core material 3 can be made smaller.

Further, in the above-described embodiment, the cross-sectional view of the inner wall surface of the holding portion 71 of the mouth portion 20 of the drug container 2 is circular, but as another modification, the cross-sectional view of the inner wall surface of the holding portion 71 is seen. The shape may be a polygonal shape such as a triangle shape or a quadrangular shape, or may be various other shapes such as an elliptical shape. In this modification, as shown in FIG. 9, the outer diameter of the liquid absorbing core material 3 is made larger than the diameter of the circle S2 inscribed in the cross-sectional view shape of the inner wall surface of the holding portion 71, whereby the liquid absorbing core material is made larger. When the cross-sectional view shape of 3 is superimposed on the cross-sectional view shape of the inner wall surface of the holding portion 71, a part of the cross-sectional view shape of the liquid absorbing core material 3 is outside the cross-sectional view shape of the inner wall surface of the holding portion 71. It sticks out. Therefore, the cross-sectional view shape of the inner wall surface of the holding portion 71 can be made smaller than the cross-sectional view shape of the portion sandwiched by the holding portion 71 of the liquid absorbing core material 3, whereby the liquid absorbing core material 3 can be made smaller. In the portion sandwiched by the sandwiching portion 71, a part of the outer peripheral surface thereof is pressed by the inner wall surface of the sandwiching portion 71. As a result, since the liquid-absorbing core material 3 inserted into the drug container 2 is tightened by the holding portion 71 of the mouth portion 20, it is possible to promote the function of sucking up the drug solution due to the capillary phenomenon of the liquid-absorbing core material 3.

The cross-sectional view shape of the liquid absorbing core material 3 may be a shape other than the circular shape, and the cross-sectional view shape of the inner wall surface of the holding portion 71 may be a shape other than the circular shape. Also in this modification, although not shown, the cross-sectional view shape of the liquid-absorbent core material 3 when the cross-sectional view shape of the liquid-absorbent core material 3 is superimposed on the cross-sectional view shape of the inner wall surface of the holding portion 71. By designing the cross-sectional view shape of both so that a part of the above is projected to the outside of the cross-sectional view shape of the inner wall surface of the holding portion 71, the cross-sectional view shape of the inner wall surface of the holding portion 71 can be changed to the liquid absorbing core material 3. It can be made smaller than the cross-sectional view shape of the portion sandwiched by the sandwiching portion 71.

Further, in the above-described embodiment, the liquid absorbing core material 3 exhibits a circular shape having substantially the same outer diameter in cross-sectional view over the entire length, but as another modification, at least a portion sandwiched by the sandwiching portion 71 has a cross-sectional cross section. The visual shape may be larger than the cross-sectional visual shape of the inner wall surface of the sandwiching portion 71. When the cross-sectional view of both is circular, the outer diameter of the portion sandwiched by the sandwiching portion 71 of the liquid absorbing core material 3 is made larger than the inner diameter of the sandwiching portion 71, preferably 1.05. It is doubled or more, more preferably 1.1 times or more.

Further, in the above-described embodiment, the mouth portion 20 of the drug container 2, specifically, the inner plug 7, has a different size (inner diameter) in cross-sectional view between the holding portion 71 and the fitting portion 70, but other As a modification of the above, the same size (inner diameter) as the cross-sectional view shape of the sandwiching portion 71 may be used in all directions in the height direction.

Further, in the above-described embodiment, the drug container 2 includes the container body 6 and the inner plug 7, and the mouth portion 20 is composed of the tubular body 61 and the inner plug 7 of the container body 6, but as another modification, the mouth The portion 20 may be composed of only the tubular body 61 of the container body 6. In this modification, the tubular body 61 of the container body 6 is formed so as to include the holding portion having the same structure as the holding portion 71 of the inner plug 7.

Further, in the above-described embodiment, the liquid pool portion 65 is located at the center of the inner bottom surface of the bottom portion 62 of the drug container 2, but as another modification, if it is within the range covered by the liquid absorbing core material 3 from above. , The position may be displaced from the center of the inner bottom surface of the drug container 2.

Further, in the above-described embodiment, the tubular body 61 of the drug container 2 is located directly above the center of the bottom portion 62, but as another modification, the tubular body 61 may be displaced from directly above the center of the bottom portion 62. Accordingly, the liquid pool portion 65 is located on the inner bottom surface of the bottom portion 62 of the drug container 2 as long as it is within the range covered from above by the liquid absorbing core material 3 inserted into the drug container 2 from the tubular body 61. You may be doing it.

Further, in the above-described embodiment, the liquid-absorbent core material 3 is inserted into the drug container 2 so as to stand upright in the drug container 2 in the vertical direction, but as another modification, the liquid-absorbent core material 3 is a drug.
