Description

The present invention relates to an air freshener bottle.

A known example of an air freshener bottle is one in which the liquid air freshener is stored inside the bottle body, a water absorbent rod is immersed in the liquid air freshener and the upper end of the water absorbent rod is in contact with filter paper, the filter paper is covered with an outer lid, and an opening for ventilation is formed in the outer lid. The water absorbent rod is immersed in the liquid air freshener by being inserted into the bottle body from the neck portion. The filter paper is held by a filter paper stand.
According to this fragrance bottle, the liquid fragrance stored in the bottle body is sucked up by the water absorbing rod, the sucked up liquid fragrance is used to moisten the filter paper, and the scent volatilized from the liquid fragrance moistened on the filter paper is diffused to the outside through the opening of the outer lid.
Among the air freshener bottles, there is known one in which the opening of the outer lid is formed at the top, and the scent of the air freshener liquid moistened with filter paper is diffused to the outside from the opening at the top (see, for example, Patent Document 1).

Patent No. 4795330

However, the fragrance bottle in Patent Document 1 has an opening in the outer lid only at the top. This makes it difficult to properly disperse the scent of the fragrance liquid moistened on the filter paper from the opening to the outside. One possible solution to this problem is to form openings in the peripheral wall of the outer lid and the peripheral wall of the filter paper base in addition to the opening at the top of the outer lid, and to connect these openings. This would allow the fragrance of the fragrance liquid to disperse to the outside from the opening at the top of the outer lid, and also allow the fragrance of the fragrance liquid to disperse to the outside from the opening in the peripheral wall of the outer lid.

However, before use, the opening in the neck of an air freshener bottle is sealed by the inner cap, which is screwed onto the threads (screw threads) on the neck. Therefore, when starting to use the air freshener bottle, the inner cap must be removed from the neck. For example, if openings are formed in the peripheral wall of the outer lid or the peripheral wall of the filter paper base, the threads formed on the neck will be visible through the openings in the respective peripheral walls, making it difficult to maintain the appearance of the air freshener bottle.

The objective of the present invention is to provide an air freshener bottle that can ensure optimal fragrance dissipation and improves appearance by hiding the threads.

In order to solve the above problems, the present invention proposes the following means.
(1) The fragrance bottle of the present invention comprises a bottle body in which fragrance liquid is stored and which has a threaded portion to which an inner cap that is removed when in use can be attached or removed; an outer lid that is detachable from the bottle body so as to cover the threaded portion and has a first opening for ventilation formed in the peripheral wall; and a filter paper base that is placed inside the outer lid, holds filter paper in a position that contacts the water absorption rod protruding from the bottle body, and has a second opening for ventilation that covers the threaded portion and is formed in a position that avoids facing the first opening.

With the above configuration, a first opening is formed in the peripheral wall of the outer lid, connecting the outside and inside of the outer lid through the first opening. Furthermore, a second opening is formed in the filter paper base. Therefore, inside the outer lid, the scent volatilized from the liquid fragrance moistened on the filter paper to the inside of the outer lid can be diffused to the outside through the first opening. Furthermore, the scent volatilized from the liquid fragrance moistened on the filter paper to the inside of the filter paper base can be diffused to the outside through the first opening via the second opening. Therefore, the scent volatilized from the liquid fragrance moistened on the filter paper can be diffused to the outside effectively. This ensures optimal fragrance diffusion from the liquid fragrance.

Furthermore, the second opening of the filter paper base is formed away from the position facing the first opening. This allows the peripheral wall of the filter paper base to be positioned facing the first opening. This allows the peripheral wall of the filter paper base to cover the threaded portion of the bottle body. This improves the appearance of the fragrance bottle by hiding the threaded portion formed on the bottle body from view of the first opening.

(2) In the above aspect, the filter paper stand may have a base portion on which the filter paper is placed and a protrusion portion provided on the periphery of the base portion to hold the filter paper placed on the base portion.

With this configuration, by providing protrusions on the periphery of the base, the filter paper placed on the base can be held by the protrusions. This prevents the filter paper from shifting forward, backward, left, or right from the position on the base, or tilting up or down. This ensures that the filter paper is securely held in the position where it is placed on the base.

(3) In the above aspect, the outer lid may be elliptical in top view and have another opening for ventilation formed at the top, and the base may be formed along the outer lid and positioned inside the outer lid in accordance with the orientation of the ellipse of the outer lid.

With this configuration, the outer lid is formed in an oval shape, and the base is formed along the outer lid. Furthermore, the base is positioned inside the outer lid in accordance with the orientation of the outer lid. Therefore, the outer lid can prevent the base (i.e., the filter paper base) from rotating circumferentially relative to the outer lid. This prevents the second opening of the filter paper base from overlapping the first opening of the outer lid. Therefore, the threaded portion formed on the bottle body can be more reliably hidden from view through the second opening and the first opening.

In addition, another opening for ventilation has been formed at the top of the outer lid. This allows the scent volatilized inside the outer lid from the liquid fragrance moistened on the filter paper to be dispersed to the outside through the other opening. This allows the scent volatilized from the liquid fragrance moistened on the filter paper to be dispersed to the outside efficiently.

(4) In the above aspect, the outer lid may have a first rib protruding inward from the inner peripheral surface of the peripheral wall and a second rib protruding inward from the inner surface of the top.

With this configuration, the first rib protrudes from the inner peripheral surface of the peripheral wall, allowing the filter paper base to be engaged with the first rib. This allows the filter paper base to be held inside the outer lid by the first rib. This allows the filter paper base and the filter paper placed on the paper base to be held together inside the outer lid.
When starting to use the fragrance bottle, it is necessary to remove the outer lid, filter paper base, and filter paper from the bottle body, and then remove the inner cap from the bottle body. Therefore, by holding the filter paper base and filter paper together inside the outer lid, when starting to use the fragrance bottle, it is possible to remove the filter paper base and filter paper from the bottle body together with the outer lid by removing the outer lid from the bottle body. This makes it easy to attach and detach the outer lid, filter paper base, and filter paper to and from the bottle body.

Furthermore, by having the second rib protrude from the inner surface of the apex, the second rib can prevent the entire upper surface of the filter paper from being pressed against the inner surface of the apex. This prevents the entire upper surface of the filter paper from being pressed against and sticking to the inner surface of the apex. This allows, for example, the scent of an air freshener liquid moistened onto the filter paper to evaporate favorably from the entire surface of the filter paper, allowing the scent to be dissipated well.

(5) In the above aspect, the filter paper base may have another opening formed in the base portion on which the filter paper is placed.

With this configuration, by forming another opening in the base, the other opening can be connected to the outside of the outer lid via the first opening in the outer lid. This allows the scent that volatilizes from the liquid fragrance moistened in the filter paper to dissipate to the outside of the outer lid via the other opening and the first opening.

This invention ensures optimal fragrance dissipation and improves appearance by hiding the threads.

1 to 5 , an air freshener bottle 10, for example, uses an absorbent rod 13 to suck up air freshener liquid (not shown) stored in a bottle body 12, moistens filter paper 17 with the absorbed air freshener liquid, and causes a fragrance to be released from the air freshener liquid moistened by the filter paper 17. The air freshener bottle 10 includes, for example, a bottle body 12, an absorbent rod 13, an inner cap 14, an outer lid (top lid) 15, a filter paper base 16, and the filter paper 17.

<Bottle body>
The bottle body 12 has a peripheral wall 21 formed in an oval shape when viewed from above, and the lower end of the peripheral wall 21 is closed by a bottom 22. The upper end of the peripheral wall 21 of the bottle body 12 is closed by a top 23, and a neck 24 protrudes upward in a cylindrical shape from the center of the top 23. The neck 24 is formed in a cylindrical shape, and an opening thereof communicates with the interior of the bottle body 12. The neck 24 has a threaded portion (thread) 24a formed on its outer periphery. The bottle body 12 also has a recess 25 formed circumferentially at the upper end of the peripheral wall 21.

<Water absorption stick>
The bottle body 12 is filled with aromatic liquid through the opening of the neck 24 and stored inside. An absorbent rod 13 is inserted into the bottle body 12 through the opening of the neck 24. The absorbent rod 13 is immersed in the aromatic liquid by being inserted inside the bottle body 12, with its upper part protruding from the neck 24. The absorbent rod 13 sucks up the aromatic liquid stored in the bottle body 12 and supplies the sucked-up aromatic liquid from the upper end to a filter paper 17 (described below), wetting the filter paper 17 with the aromatic liquid.

<Inner cap>
Before the fragrance bottle 10 is put into use, the inner cap 14 is attached to the neck 24 of the bottle body 12. Specifically, the inner cap 14 is detachably attached by threaded engagement to the threaded portion 24a of the neck 24. By attaching the inner cap 14 to the neck 24, the upper portion 13a of the water absorption rod 13 protruding from the neck 24 is covered with the inner cap 14, and the opening of the neck 24 is closed with the inner cap 14. When the fragrance bottle 10 is first used (i.e., when the fragrance bottle 10 is used), the inner cap 14 is released from the threaded engagement to the threaded portion 24a and is removed from the neck 24.

<Outer lid>
The outer lid 15 is detachably attached to the bottle body 12. The outer lid 15 is formed in an elliptical shape when viewed from above. The outer lid 15 has a peripheral wall 31, a top portion 32, a first rib 33, and a second rib 34.
The peripheral wall 31 is formed in the same elliptical shape as the peripheral wall 21 of the bottle body 12 when viewed from above. For example, the peripheral wall 31 has multiple protrusions 36 that protrude inward from the inner surface of the lower end at intervals in the circumferential direction. The multiple protrusions 36 engage with the recesses 25 of the bottle body 12, allowing the outer lid 15 to be detachably attached to the bottle body 12. The peripheral wall 31 has a pair of first vent holes (first openings) 37.

One of the pair of first ventilation holes 37 is opened on the left side of the peripheral wall 31, and the other first ventilation hole 37 is opened on the right side of the peripheral wall 31. The pair of first ventilation holes 37 are formed symmetrically. Hereinafter, one of the first ventilation holes 37 will be referred to as the "first ventilation hole 37," and a description of the other first ventilation hole 37 will be omitted. The first ventilation hole 37 is a ventilation opening formed in the peripheral wall 31 to communicate between the outside and inside of the outer lid 15. The first ventilation hole 37 is formed, for example, in a circular shape, but any shape can be selected.

The upper end of the peripheral wall 31 is closed by the top 32. The top 32 has a second ventilation hole (another opening) 38. The second ventilation hole 38 is a ventilation opening formed in the top 32 to communicate between the outside and inside of the outer lid 15. The second ventilation hole 38 is formed, for example, in the center of the top 32, in an oval shape along the outer periphery of the top 32, but the shape can be selected arbitrarily.

FIG. 6 is a perspective view of the outer cover of the embodiment as seen from below.
5 and 6 , the peripheral wall 31 has first ribs 33 on its inner peripheral surface. The first ribs 33 are arranged on the inner peripheral surface of the peripheral wall 31 at intervals below the top portion 32. The first ribs 33 protrude from the inner peripheral surface toward the inside of the outer lid 15, and are provided in plurality at intervals in the circumferential direction. In the embodiment, four first ribs 33 are described as an example of the plurality of first ribs 33, but the number of first ribs 33 can be selected arbitrarily.
The first rib 33 is disposed above the pair of first ventilation holes 37. The distance between the first rib 33 and the top 32 is set in the vertical direction so that a base portion 41 of the filter paper holder 16 and the filter paper 17, which will be described later, can be fitted into the space.

The top 32 also has a second rib 34 on its inner surface. The second rib 34 is arranged along the periphery of the second vent hole 38. Specifically, the second rib 34 is formed in an oval shape that continues along the periphery of the second vent hole 38 on the inner surface of the top 32, and protrudes from the inner surface of the top 32 toward the inside of the outer lid 15. In the embodiment, an example is described in which the second rib 34 continues along the periphery of the second vent hole 38, but it is also possible to provide multiple second ribs 34 at intervals in the circumferential direction along the periphery of the second vent hole 38.
Inside the outer lid 15 formed in this manner, a filter paper base 16 and filter paper 17 are arranged.

<Filter paper stand>
Fig. 7 is a perspective view of the filter paper base of the embodiment with filter paper placed thereon, as viewed from above and to the left of the front. Fig. 8 is a perspective view of the filter paper base of the embodiment, as viewed from above and to the left of the front.
As shown in Figures 5, 7, and 8, the filter paper base 16 has a base portion 41, a pair of first protrusions (protrusions) 42, a pair of second protrusions (protrusions) 43, and a mouth portion (peripheral wall of the filter paper base 16) 44.

The base 41 is formed along the peripheral wall 31 of the outer lid 15 when the base 41 is disposed inside the outer lid 15. For example, the left edge 41b of the peripheral edge 41a of the base 41 is curved along the left edge of the peripheral wall 31, and the right edge 41c is curved along the right edge of the peripheral wall 31. Furthermore, the peripheral edge 41a has a pair of straight central edges 41d connecting the left edge 41b and the right edge 41c. The base 41 (i.e., the filter paper base 16) is formed along the peripheral wall 31 of the outer lid 15 and is disposed inside the outer lid 15 in accordance with the orientation of the outer lid 15.
In this state, the filter paper base 16 can be prevented from shifting in the circumferential direction relative to the outer lid 15. In other words, the filter paper base 16 is held by the peripheral wall 31 of the outer lid 15 in a state where it is positioned inside the outer lid 15 in accordance with the orientation of the outer lid 15. The entire filter paper 17 is placed on the base portion 41.

A pair of first protrusions 42 protruding upward are provided on each of the left and right edge portions 41b and 41c. The first protrusions 42 on the left and right edge portions 41b and 41c are bilaterally symmetrical. Therefore, the first protrusions 42 on the left and right edge portions 41b and 41c are given the same reference numerals, and only the first protrusions 42 on the left and right edge portions 41b will be described, with the description of the first protrusions 42 on the right edge portion 41c omitted.

The first protrusion 42 has a protrusion body 42a and a claw portion 42b. The protrusion body 42a protrudes upward from the center of the left edge 41b in the front-to-rear direction. Therefore, the pair of protrusion bodies 42a are positioned along the left and right sides of the periphery 17a of the filter paper 17 placed on the base 41, preventing the filter paper 17 from shifting (moving) in the left-to-right direction.
The claws 42b protrude inward from the upper end of the projection body 42a along the base 41. The pair of claws 42b are positioned above the filter paper 17 placed on the base 41, and prevent the filter paper 17 from tilting (moving) in the vertical direction.

Furthermore, a pair of second protrusions 43 protruding upward are provided on each of the pair of central edges 41d. The pair of second protrusions 43 are formed identically. Therefore, the pair of second protrusions 43 will be described using the same reference numerals. The pair of second protrusions 43 are positioned along the front and rear sides of the periphery 17a of the filter paper 17 placed on the base 41, and prevent the filter paper 17 from shifting (moving) in the front-to-rear direction.

As a result, the pair of first protrusions 42 and the pair of second protrusions 43 prevent the filter paper 17 placed on the base 41 from shifting in the front-to-back and left-to-right directions and from tilting up and down, thereby holding the filter paper 17 in a predetermined position. With the filter paper 17 held in a predetermined position, the base 41 elastically deforms to climb over the four first ribs 33 (see also FIG. 6 ) formed on the outer lid 15 from below to above. Thus, the base 41 is held in a position above the four first ribs 33.
An opening 44, which will be described later, is provided in the center of the base 41. The base 41 has a plurality of third ventilation holes (another opening) 46 formed around the opening 44. In the embodiment, six third ventilation holes 46 are described as an example of the plurality of third ventilation holes 46, but the number of third ventilation holes 46 can be selected arbitrarily.

FIG. 9 is a perspective view of the filter paper base of the embodiment, seen from below and near the left front side.
As shown in Figures 5, 8, and 9, the mouth portion 44 protrudes downward from the center of the base portion 41. That is, the mouth portion 44 is integrally connected to the center of the base portion 41. The mouth portion 44 is formed in a cylindrical shape, with its upper end opening at the center of the base portion 41. The mouth portion 44 also opens from its lower end 44a so that it can be fitted onto the neck portion 24. When the mouth portion 44 is fitted onto the neck portion 24, the inner cap 14 (see Figure 4) and the threaded portion 24a of the neck portion 24 are covered by the mouth portion 44. Specifically, before the fragrance bottle 10 is used, the mouth portion 44 covers the inner cap 14. After the fragrance bottle 10 is used, the mouth portion 44 covers the threaded portion 24a of the neck portion 24.

Furthermore, the mouth portion 44 has a pair of ventilation holes (second openings) 47. The pair of ventilation holes 47 are formed in the mouth portion 44 to communicate the inside and outside of the mouth portion 44. The pair of ventilation holes 47 are opened at the lower end portion 44a of the mouth portion 44. The shape of the pair of ventilation holes 47 can be selected arbitrarily.
One of the pair of vent holes 47 opens to the front of the opening 44, and the other vent hole 47 opens to the back of the opening 44. Here, one of the pair of first vent holes 37 opens to the left side of the peripheral wall 31, and the other first vent hole 37 opens to the right side of the peripheral wall 31. Therefore, the pair of vent holes 47 are positioned so as not to face the pair of first vent holes 37. This allows the peripheral wall 31 of the outer lid 15 to cover the threaded portion 24a and the upper portion 13a of the water absorption stick 13, which are exposed to the outside of the opening 44 through the pair of vent holes 47 (see FIG. 2).

<Filter paper>
As shown in Figures 5 and 7, filter paper 17 is placed on the base 41 of the filter paper holder 16. The filter paper 17 has a peripheral edge 17a formed along the left edge 41b, right edge 41c, and pair of central edges 41d of the base 41 (the front central edge 41d is shown in Figure 7). The entire filter paper 17 is placed on the base 41. In this state, the filter paper 17 is positioned inside the pair of protrusion bodies 42a and the pair of second protrusions 43, and below the pair of claws 42b. The pair of protrusion bodies 42a and the pair of claws 42b constitute a pair of first protrusions 42. Therefore, the filter paper 17 is held in place by the pair of first protrusions 42 and the pair of second protrusions 43 so that it does not shift (move) from the state where it is placed on the base 41.

With the filter paper 17 held in a predetermined position on the base 41, the base 41 is held above the four first ribs 33 (see also FIG. 6 ), thereby holding the filter paper 17 between the base 41 and the top 32 of the outer lid 15. Thus, the filter paper 17 is held inside the outer lid 15 together with the base (i.e., the filter paper base 16). The upper surface 17b of the filter paper 17 is exposed to the outside of the outer lid 15 through the second ventilation hole 38. The lower surface 17c of the filter paper 17 is exposed below the base 41 through multiple third ventilation holes 46 (see FIG. 8 ).
In this state, when the outer lid 15 is attached to the bottle body 12, the filter paper 17 is held in a position where it contacts the upper part of the water-absorbing rod 13 by the base 41. The filter paper 17 moistens the aromatic liquid absorbed by the water-absorbing rod 13 and dissipates the scent that has evaporated from the aromatic liquid.

As shown in Figures 4 and 5, before use, the fragrance bottle 10 has the inner cap 14 attached to the neck portion 24 (specifically, the threaded portion 24a) of the bottle body 12 by a threaded connection. Therefore, before use, the fragrance bottle 10 has the outer lid 15 attached to the bottle body 12, so that the inner cap 14 exposed to the outside of the mouth portion 44 through the pair of vent holes 47 can be covered by the peripheral wall 31 of the outer lid 15.

On the other hand, when the fragrance bottle 10 is first used, the inner cap 14 is removed from the threaded portion 24a of the neck portion 24. Therefore, when the fragrance bottle 10 is first used, the outer lid 15 is attached to the bottle body 12, so that the threaded portion 24a exposed to the outside of the mouth portion 44 through the pair of vent holes 47 can be covered by the peripheral wall 31 of the outer lid 15.
Can be covered.
Here, by attaching the outer lid 15 to the bottle body 12 , a communication space 52 is formed inside the outer lid 15 between the peripheral wall 31 of the outer lid 15 and the mouth portion 44 .

As described above, according to the embodiment of the fragrance bottle 10, as shown in Figures 5, 8, and 9, a pair of first ventilation holes 37 are formed in the peripheral wall 31 of the outer lid 15. Therefore, the first ventilation holes 37 connect the communication space 52 inside the outer lid 15 to the outside of the outer lid 15. In addition, six third ventilation holes 46 are formed around the mouth 44 of the base 41. The six third ventilation holes 46 are connected to the outside of the outer lid 15 via the communication space 52 and the pair of first ventilation holes 37. This allows the scent volatilized from the fragrance liquid moistened to the filter paper 17 to dissipate to the outside of the outer lid 15 via the six third ventilation holes 46, the communication space 52, and the pair of first ventilation holes 37, as indicated by arrow A.

Furthermore, the base 41 has an opening in the center via the mouth 44, and a pair of ventilation holes 47 formed in the mouth 44. Therefore, the central opening of the base 41 is connected to the outside of the outer lid 15 via the inside of the mouth 44, the pair of ventilation holes 47, the communication space 52, and the pair of first ventilation holes 37. This allows the scent volatilized from the aromatic liquid moistened to the filter paper 17 to dissipate to the outside of the outer lid 15 as indicated by arrow B via the central opening of the base 41, the inside of the mouth 44, the pair of ventilation holes 47, the communication space 52, and the pair of first ventilation holes 37.

In addition, a second ventilation hole 38 is formed in the top 32 of the outer lid 15. The second ventilation hole 38 connects the space above the base 41 inside the outer lid 15 to the outside. This allows the scent volatilized from the liquid fragrance moistened in the filter paper 17 to dissipate outside the outer lid 15 through the second ventilation hole 38 as shown by arrow C.

In this way, the scent of the liquid fragrance moistened to the filter paper 17 is diffused to the outside of the outer lid 15 through a pair of first ventilation holes 37 and second ventilation holes 38 opened in the outer lid 15, thereby ensuring good diffusion of the scent from the liquid fragrance.

Here, the first ventilation hole 37 and the second ventilation hole 38 of the outer lid 15 are formed with a relatively small opening ratio relative to the surface area of the outer lid 15 (i.e., the surface area of the peripheral wall 31 and the top 32). This allows the scent of the liquid fragrance moistened into the filter paper 17 to be diffused faintly to the outside of the outer lid 15 through the pair of first ventilation holes 37 and second ventilation holes 38.

Furthermore, a pair of vent holes 47 are formed in the mouth 44 of the filter paper base 16 away from the positions facing the pair of first vent holes 37 in the outer lid 15. This allows the mouth 44 to cover the threaded portion 24a of the neck 24 formed in the bottle body 12. This allows the mouth 44 to hide the threaded portion 24a of the neck 24 so that it is not visible from the first vent holes 37, thereby improving the appearance of the fragrance bottle 10.

Furthermore, the base portion 41 of the filter paper stand 16 has first protrusions 42 on the left edge 41b and right edge 41c, respectively, and second protrusions 43 on the pair of central edges 41d. The pair of first protrusions 42 and the pair of second protrusions 43 can prevent the filter paper 17 placed on the base portion 41 from shifting in the front-to-back or left-to-right directions, or tilting up and down. This allows the filter paper 17 to be securely held in the position where it is placed on the base portion 41.

Furthermore, the peripheral wall 31 of the outer lid 15 is formed in an oval shape, and the base portion 41 of the filter paper base 16 is formed along the outer lid 15. The filter paper base 16 is positioned inside the outer lid 15 with this base portion 41 aligned with the oval orientation of the outer lid 15. Therefore, the peripheral wall 31 of the outer lid 15 prevents the filter paper base 16 from rotating in the circumferential direction relative to the outer lid 15. This prevents the pair of vent holes 47 formed in the opening portion 44 of the filter paper base 16 from overlapping the pair of first vent holes 37 formed in the outer lid 15. Therefore, the threaded portion 24a formed in the neck portion 24 can be more reliably hidden by the opening portion 44 so that it cannot be seen from the first vent holes 37 through the vent holes 47.

In addition, by having the first rib 33 protrude from the inner peripheral surface of the peripheral wall 31 of the outer lid 15 toward the inside of the outer lid 15, the base portion 41 of the filter paper holder 16 can be engaged with the first rib 33. Therefore, the base portion 41 can be removably held inside the outer lid by the first rib 33. This allows the filter paper holder 16 and the filter paper 17 placed on the base portion 41 to be held together inside the outer lid 15.
Here, when starting to use the fragrance bottle 10, it is necessary to remove the outer lid 15, filter paper base 16, and filter paper 17 from the bottle body 12, and then remove the inner cap 14 from the threaded portion 24a of the bottle body 12. Therefore, by holding the filter paper base 16 and filter paper 17 together inside the outer lid 15, when starting to use the fragrance bottle 10, simply removing the outer lid 15 from the bottle body 12 makes it possible to remove the filter paper base 16 and filter paper 17 together with the outer lid 15 from the bottle body 12. This allows the outer lid 15, filter paper base 16, and filter paper 17 to be easily attached to and detached from the bottle body 12.

Furthermore, by having the second rib 34 protrude from the inner surface of the top 32 of the outer lid 15 toward the inside of the outer lid 15, the second rib 34 can prevent the entire upper surface 17b of the filter paper 17 from being pressed against the inner surface of the top 32. This prevents the entire upper surface 17b of the filter paper 17 from being pressed against and sticking to the inner surface of the top 32. This allows, for example, the scent of an air freshener liquid moistened on the filter paper 17 to evaporate favorably from the entire surface of the filter paper 17, allowing the scent to be dissipated well.

The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
In the above embodiment, an example has been described in which a pair of first ventilation holes 37 are opened in the peripheral wall 31 of the outer lid 15, but the number of first ventilation holes 37 can be selected arbitrarily.
Furthermore, in the above embodiment, an example has been described in which one second vent hole 38 is opened in the top portion 32 of the outer lid 15, but the number of second vent holes 38 can be selected arbitrarily.
Furthermore, in the above embodiment, an example has been described in which a pair of ventilation holes 47 are formed in the opening 44 of the filter paper base 16, but the number of ventilation holes 47 can be selected arbitrarily.

In addition, the components in the above embodiments may be replaced with well-known components as appropriate, and the above-described modifications may be combined as appropriate, without departing from the spirit of the present invention.
