FIG. 12 shows a partial cross-sectional front view of the volatilization apparatus 11 shown in FIG.
In the figure, the volatilization device 10 ′ is composed of a storage container 14 in which the liquid preparation L is accommodated, and an outer container 11 ′ attached above the storage container 14. The storage container 14 is composed of a container main body 14a in which the liquid preparation L is accommodated, and an opening 14b connected to the upper part of the container main body 14a. The opening 14b is a cylindrical protrusion, and the lower part on the inner periphery is a container. It is configured to communicate with the main body 14a.
A liquid absorbing member 15 functioning as a volatilizing member is inserted into the opening 14b of the storage container 14 through a hooked inner plug 17 ', one end of which is immersed in the liquid preparation L in the storage container 14, and the other Is arranged so that the end of the outer side is exposed to the outside of the storage container 14. The inner stopper 17 'with the hook is fitted to the inner peripheral surface of the opening 14b of the storage container 14, and the hook is fixedly supported in a state of closing the top of the opening 14b.

  The outer container 11 ′ is fitted into a hollow body 12 ′ disposed so as to cover a portion exposed from the storage container 14 of the liquid absorbing member 15 and an opening provided in an upper part of the hollow body 12 ′. The rotation cap 13 ′ is composed of a dish-shaped rotation operation part 13a, a cylindrical inner cylinder part 13b projecting downward from the center of the rotation operation part 13a, and a rotation. The outer cylinder portion 13c is provided on the periphery of the operation portion 13a so as to protrude downward. The lower end portion of the inner cylindrical portion 13b is in contact with the flange portion of the flanged inner plug 17 'to keep a seal between them.

The hollow body 12 'has an upper opening 12c formed above the body main body 12a so as to be fitted to the body main body 12a, the outer cylindrical portion 13c of the rotating cap 13', and a smaller diameter than the upper opening 12c. The body part inner cylinder 12b is formed on the same axis. The hollow body portion 12 ′ is arranged such that the body portion inner cylinder 12b is in sliding contact with the outer periphery of the inner cylinder portion 13b of the rotation cap 13 ′.

13 is a side cross-sectional view of the volatilization apparatus shown in FIG.
In the figure, a flange portion 14 c is formed in the opening portion 14 b of the storage container 14. A claw portion 12e is formed inside the hollow body portion 12 ′. The outer container 11 ′ can be reliably fixed to the storage container 14 by engaging the claw part 12 e with the flange part 14 c in the opening 14 b of the storage container 14. The shape of the flange portion 14c can be arbitrarily set as long as it can engage with the claw portion 12e.

  Further, a clip attachment portion 12k (see also FIG. 11B) is provided on the back surface of the hollow body portion 12 ', and the clip 18 is attached by fitting a clip-side attachment portion 18a therein. The clip 18 includes a clip connecting portion and four tightening portions whose one ends are held by the clip connecting portion. The clip connecting portion is made of a metal fitting having a predetermined elastic stress such as metal. One end of the tightening portion is formed integrally with the clip connecting portion, and the other end is made of resin that covers a part of the clip connecting portion. The clip 18 is configured such that upper and lower tightening portions are tightened by elastic stress. When the clip 18 is used to be inserted and fixed to the air conditioner outlet of the automobile, the air blown out from the air conditioner outlet enters the hollow body 12 ′ through the air intake hole 21 on the back surface of the hollow body 12 ′. , Enters the space where the liquid absorbing member 15 is located through the opening (described later) of the hollow body 12 ', exits from another opening (described later) while containing the active ingredient through the periphery thereof, The active ingredient is volatilized from the volatilization hole 16 into the vehicle.

FIG. 14 is a cross-sectional perspective view illustrating the functions of the hollow body 12 ′ and the rotating cap 13 ′. Below the inner cylindrical portion 13b (FIG. 12), volatilization openings 13s and 13t (two locations above and below in FIG. 14A) are formed in the circumferential direction with an opening angle of about 90 degrees. In addition, volatilization openings 12s and 12t (two locations on the upper and lower sides in (b) of FIG. 14A) having an opening angle of about 90 degrees are also formed in the body cylinder part 12b (FIG. 12) in the circumferential direction.
The rotation cap 13 ′ is attached to the hollow body 12 ′ so as to be rotatable about 90 degrees with the center of the liquid absorbing member 15 as the rotation center axis. Two stoppers 12x, 12y are formed on the hollow body 12 'on the front, rear, left, and right, respectively, so that the rotation cap 13' cannot be rotated any further. The rotation cap 13 'also has projections 13x that abut against the stoppers 12x, 12y. Are formed one after the other. In the drawing, among these stoppers and protrusions, those in the front portion are depicted as stoppers 12x, 12y, and 13x.

The function of the rotating cap 13 'is as follows.
When the rotating cap 13 ′ is rotated, the inner cylindrical portion 13b integrated therewith rotates, so that the volatilization openings 13s and 13t also move in the circumferential direction. Therefore, when the rotation cap 13 ′ is rotated in the clockwise direction and the protrusion 13x is rotated to the maximum until it hits the stopper 12x as shown in FIG. 14A, the volatilization openings 13s and 13t and the body cylinder portion 12b. The volatilization openings 12 s and 12 t completely overlap with each other and become the maximum opening.
Therefore, the amount of air passing here is maximized, and the volatilization amount of the active ingredient is also maximized ((b) in FIG. 14A). As described above, in (b) of FIG. 14 (a), the wall portion of the barrel cylinder portion 12b and the wall portion of the inner cylinder portion 13b overlap, and a large amount of wind B1 enters from the back and passes through the volatilization opening. You can see that it goes out of the front volatilization hole.

  Next, when the amount of air passing therethrough is to be reduced to about half, as shown in FIG. 14B, the rotating cap 13 ′ is rotated about 45 degrees counterclockwise as compared with the case of FIG. Since the wall 13b1 of the inner cylinder part 13b blocks the volatilization openings 12s and 12t of the trunk cylinder part 12b by about half, the amount of air blown out from the automobile air conditioner is weakened, and the diffusion of the active ingredient of the liquid formulation L is reduced. ((B) in FIG. 14B). Therefore, in (b) of FIG. 14B, the amount of air entering from the back surface decreases, and a small amount of air B2 passes through the volatilization opening and exits from the volatilization hole.

  Thus, according to the prior invention, the volatilization openings 12s and 12t of the rotating cap 13 ′ are rotated from the position where the air amount is maximum to an arbitrary position so that the volatilization openings 12s and 12t of the rotating cap 13 ′ are the barrel part 12b. Since it is shifted from the volatilization openings 12s and 12t and is instead blocked by the wall portion 13b1, the opening area can be adjusted, and the volatilization amount of the active ingredient can be adjusted.

By such a volatilization apparatus according to the prior invention of the present applicant, a volatilization apparatus capable of volatilizing an active ingredient in a sufficient amount and stably was obtained.
However, it has been found that there are points to be improved in this volatilization apparatus. That is, even when the opening is completely closed so that there is no diffusion when not in use, a slight odor can be felt inside the vehicle. That is, in order to prevent diffusion when not in use, as shown in FIG. 14C, (a), the rotating cap 13 ′ is further rotated counterclockwise so that the protrusion 13x of the rotating cap 13 serves as the stopper 12y. When brought into contact, the wall portion 13b1 of the inner cylinder portion 13b completely covers the volatilization openings 12s and 12t of the barrel portion cylinder portion 12b, so that the wall portion 12b1 and the wall portion extend over 360 degrees around the liquid absorbing member 15. The amount of air blown from the automobile air conditioner will not reach the liquid absorbing member 15, and the active ingredient of the liquid preparation L should not diffuse outside the volatilization apparatus 10 ′.
In reality, however, as can be seen in (b) of Fig. (C), the wind B3 emerged from the volatilization hole in the front, and a slight odor was felt inside the vehicle.

When the cause was investigated, the cause is not between the wall portion 13b1 of the inner cylinder portion and the volatilization openings 12x and 12y of the barrel portion, but the collar portion of the hooked plug 17 ', It has been found that it is between the inner cylinder portion 13b1 and the front end portion of the body inner cylinder 12b1.
Accordingly, an object of the present invention is to provide a sealed volatilization device which is made in order to solve the above-mentioned drawbacks and does not emit a slight odor from the volatilization device when not in use.

  In order to solve the above-mentioned problems, the invention of the outer container for a volatilization device according to claim 1 is provided with an inner plug with a hook inserted into the opening of the container from the tip to the hook, and the hook of the inner plug with the hook. A rotating cap having an inner cylindrical portion disposed in the opening of the container, and an outer cylindrical portion that is disposed so as to cover the outer side of the inner cylindrical portion. An outer container for a volatilization device comprising a barrel inner cylinder that is rotated by rotating the rotating cap so that the inner cylinder portion integral with the outer cylinder rotates within the barrel inner cylinder. And a means for changing the overlapping degree of the openings formed in the inner cylinder part and the body inner cylinder, respectively, and the flange part of the hooked inner plug, the inner cylinder part, and the body inner cylinder It is characterized in that a packing is interposed between the front end of each of the two.

  The invention described in claim 2 is the outer container for a volatilization device according to claim 1, further comprising a connecting portion in which the walls forming the opening at the tip of the inner cylindrical portion are connected to each other at the base. And

  According to a third aspect of the present invention, in the outer container for a volatilization device according to the first or second aspect, the barrel inner cylinder includes a rib communicating with the barrel portion.

  The invention of the outer container for a volatilization device according to claim 4 is the outer container for a volatilization device according to any one of claims 1 to 3, wherein the inside of the inner cylinder part is inside the hollow passage of the inner plug with the flange. The liquid-absorbing member reaching up to is provided.

  The invention of the volatilization apparatus according to claim 5 is characterized by comprising the outer container for volatilization apparatus according to claim 4 and a storage container in which one end of the liquid absorbing member in the outer container is immersed.

  The invention of the storage container according to claim 6 includes an inner plug with a hook inserted into the opening of the container from the tip to the hook part and having a hollow passage, a packing placed on the hook part of the inner plug with the hook, A sealing cap that presses the packing and seals the opening of the container; and a liquid absorbing member that has one end immersed in the container and extends to the inside of the sealing cap through the hollow passage of the hooked inner plug. It is characterized by that.

As described above, since the packing is interposed between the flange portion of the inner stopper with the flange, and the front end portion of the inner cylinder portion and the barrel inner cylinder portion, even a slight odor is no longer emitted when not in use. No longer come out. The volatilization effect of the active ingredient can be sustained for a long time.
In addition, since the opening formed in the inner cylindrical portion ends before a predetermined distance from the root portion of the cylindrical portion, the axial length of the wall portion is shortened, so that the strength is increased, and accordingly, the flange of the hooked inner plug Even if the part is pushed hard with this, it does not buckle, and a reliable sealing is guaranteed.
In addition, since the inner cylinder part of the trunk part is provided with a rib that communicates with the trunk part, the axial strength of the inner cylinder part increases, so that it does not buckle even when the hook part of the hooked inner plug is pushed strongly. Assured sealing is guaranteed.

Hereinafter, embodiments of the volatilization apparatus according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is an exploded perspective view of a container with a volatilization device according to the present invention.
In FIG. 1, reference numeral 10 denotes a volatilization apparatus according to the present invention, which includes a storage container 14 and an outer container 11 fitted above the storage container 14, and the outer container 11 includes a hollow body 12 and the hollow body 12. It is comprised with the rotation cap 13 inserted in opening of an upper part. A hooked inner plug 17 having a hollow passage is fitted into the opening of the storage container 14, and a liquid absorbing member 15 is inserted into the hollow passage of the hooked inner plug 17. And the packing 19 employ | adopted by this invention is mounted on the collar of the inner stopper 17 with a collar. In addition to the packing 19, the hollow body 12 'and the rotating cap 13' according to the present invention are obtained by improving the hollow body 12 'and the rotating cap 13' of the prior invention.

FIG. 2 shows a partial cross-sectional front view of the volatilization apparatus according to the present invention.
In the figure, since the storage container 14 and the liquid absorbing member 15 are the same as those described in the prior invention, the description thereof is omitted here. The hooked stopper 17 is different from that of the prior invention. The hooked stopper 17 'of the prior invention has a flat upper face of the hook, whereas the hooked stopper 17 of the present invention has a positioning function for placing the packing on the upper portion as seen in FIG. And an upwardly extending annular portion 17a. Therefore, the packing 19 is placed on the upwardly extending annular portion 17a on the flange 17b of the flanged inner plug 17 according to the present invention. The outer container 11 includes a hollow body 12 disposed so as to cover a portion exposed from the storage container 14 of the liquid absorbing member 15, and a rotating cap fitted into an opening provided in an upper part of the hollow body 12. 13.

  The rotation cap 13 protrudes downward from a dish-shaped rotation operation portion 13a, a cylindrical inner tube portion 13b protruding downward from the center of the rotation operation portion 13a, and a peripheral portion of the rotation operation portion 13a. It is comprised by the outer cylinder part 13c made. The lower end of the inner cylindrical portion 13b is in contact with the packing 19 provided according to the present invention. In the prior invention (FIG. 12), this packing 19 was not provided, and the lower end of the inner cylindrical portion 13b was in direct contact with the flange portion of the hooked inner plug 17. Therefore, in the prior invention, the contact between the lower end of the inner cylindrical portion 13b and the flange portion of the hooked inner plug 17 was not completely airtight, but the lower end of the inner cylindrical portion 13b was provided by the present invention. By contacting the packing 19, the airtightness between them was improved.

  The hollow body 12 is formed to have a smaller diameter than the upper body 12a, an upper opening 12c formed above the body 12a so as to be fitted to the outer cylinder 13c of the rotating cap 13, and the upper opening 12c. And a barrel inner cylinder 12b formed coaxially. The hollow body 12 is airtight because the body inner cylinder 12 b is in sliding contact with the outer periphery of the inner cylinder 13 b of the rotation cap 13. The lower end of the barrel inner cylinder 12b is also in contact with the packing 19 provided according to the present invention. In the prior invention (FIG. 12), this packing 19 was not provided, and the lower end of the barrel inner cylinder 12b was in direct contact with the flange portion of the hooked inner plug 17. Therefore, in the prior invention, the airtightness cannot be said to be complete when the lower end of the barrel inner cylinder 12b and the flange portion of the hooked inner plug 17 are in contact, but the lower end of the barrel inner cylinder 12b is provided with the packing 19 provided according to the present invention. The airtightness between the two was improved by abutting with.

  In addition, a rib 12z communicating with the body and the body inner cylinder 12b is formed in the hollow body 12 according to the present invention. In the prior invention (FIG. 12), this rib 12z was not present. However, according to the present invention, the packing 19 is strongly pressed at the lower end of the barrel inner cylinder 12b, so it is necessary to increase the mechanical strength of the barrel inner cylinder 12b. This is increased by the rib 12z (described later).

FIG. 3 is a side sectional view of the volatilization apparatus according to the present invention.
In the figure, 12z is a rib according to the present invention, and 19 is a packing.
A flange portion 14 c is formed in the opening portion 14 b of the storage container 14. A claw portion 12 e is formed inside the hollow body portion 12. The outer container 11 can be reliably fixed to the storage container 14 by engaging the claw part 12e with the flange part 14c in the opening 14b of the storage container 14. The shape of the flange portion 14c can be arbitrarily set as long as it can engage with the claw portion 12e. Further, the engagement with the storage container 14 may be held at the lower part of the hollow body 12.

  A decorative fitting 12m is engaged with the engaging portion 12p and fitted into the hollow barrel 12 in front of the hollow barrel 12, and a plurality of (eight in the figure) volatilization holes extending radially are provided in the decorative fitting 12m. 16 is opened. A large opening 12q (described later with reference to FIG. 9) is formed in the front of the hollow body 12 over a wide range with which the decorative fitting 12m is engaged.

  A clip 18 is attached to the hollow body 12 via an attachment portion 18a. Since the structure and function of the clip 18 are the same as those of the prior invention (FIG. 13), description thereof is omitted.

  FIG. 4 is a cross-sectional perspective view for explaining the mechanism above the storage container 14 and the shapes of the hollow body 12 and the rotary cap 13 fitted thereon, and FIG. 5 is a cross-sectional perspective view for explaining these functions. In FIG. 4, a hooked inner plug 17 having a hollow passage is fitted into the opening of the storage container 14, and a packing 19 adopted according to the present invention is placed on the hook, so that the hollow of the hooked inner plug 17 is hollow. The upper part of the liquid absorbing member 15 is exposed from the passage.

  On the other hand, the inner cylindrical portion 13b of the rotating cap 13 is fitted into the barrel inner cylinder 12b of the hollow barrel portion 12, and the whole is covered on the storage container 14, and at this time, the lower end 12f of the barrel inner cylinder 12b and The lower end 13 f of the inner cylindrical portion 13 b is firmly in contact with the packing 19.

  Below the wall portion of the inner cylinder portion 13b, there are two volatilization openings 13s and 13t with an opening angle of about 90 degrees in the circumferential direction (the front volatilization opening is 13s and the rear volatilization opening is 13t in the figure). Is formed. In addition, two volatilization openings 12s and 12t having an opening angle of about 90 degrees in the circumferential direction are also formed in the front and rear of the figure (the front volatilization opening is 12s and the rear volatilization opening is 12t) in the circumferential direction. . The rotation cap 13 is attached to the hollow body 12 so as to be rotatable about 90 degrees with the center of the liquid absorbing member 15 as the rotation center axis. Two stoppers 12x and 12y are formed on the front, rear, left and right of the upper portion of the barrel inner cylinder 12b so that the rotation cap 13 cannot rotate more than a predetermined angle (the front left and the rear right are 12x and the front right And the rear left is 12y). On the other hand, the rotation cap 13 is formed with one protrusion 13x on the front and rear to contact the stoppers 12x and 12y (only the front protrusion 13x is shown in the figure). Each protrusion 13x moves between the stopper 12x and the stopper 12y.

Next, the function of the rotating cap 13 will be described with reference to FIG.
5A and 5B are diagrams for explaining the function of each rotating cap in three states. FIG. 5A is a perspective view when the opening is fully open, FIG. 5B is when the opening is half open, and FIG. ) And a cross-sectional reduced view (b) of the rotating cap at that time viewed from below.
5A, when the protrusion 13x of the rotating cap 13 is rotated clockwise until it comes into contact with the stopper 12x of the barrel inner cylinder 12b, it rotates with the volatilization openings 12s and 12t of the barrel inner cylinder 12b. The volatilization openings 13s and 13t of the cap 13 are completely overlapped with each other to become the maximum opening ((b) of FIG. 1 (a)).
Therefore, the maximum amount of wind B1 enters from the air intake hole 21 on the back surface, passes through the volatilization openings 12s and 13s, and further passes through 12t and 13t, and exits from the volatilization hole 16 on the front surface.

  Next, when the amount of air passing therethrough is to be reduced to about half, as shown in (a) of FIG. 5 (b), the rotating cap 13 is rotated about 45 degrees counterclockwise from the case of FIG. 5 (a). As shown in (b) of FIG. 5 (b), the two wall portions 13b1 of the inner cylinder portion 13b block about half of the volatilization openings 12s and 12t of the trunk inner cylinder 12b, so that a small amount of wind B2 becomes narrower. It passes through the volatilization opening 12s and further 12t, and exits from the front volatilization hole 16.

Further, in order to prevent diffusion when not in use, as shown in FIG. 5C, the rotating cap 13 is further rotated counterclockwise so that the protrusion 13x of the rotating cap 13 is connected to the barrel inner cylinder 12b. Since the volatilization openings 12s and 12t of the barrel inner cylinder 12b are completely blocked by the wall 13b1 of the inner cylinder part 13b, the wind blown from the automobile air conditioner is applied to the liquid absorbing member 15. Can't reach.
In addition, as shown in the figure, the lower end of the barrel inner cylinder 12b and the lower end of the inner cylinder portion 13b are firmly in contact with the packing 19 provided according to the present invention, and the airtightness is increased. No wind enters between the lower end of the inner cylinder 13b and the lower end of the inner cylindrical portion 13b and the packing 19, and therefore enters from the rear surface 21 and exits from the front volatilization hole 16 as shown in FIG. There is no wind B0 going on, and there is no faint smell in the car.

  As described above, according to the present invention, the packing 19 provided according to the present invention increases the airtightness between the lower end of the body inner cylinder 12b and the lower end of the inner cylinder part 13b. Will not come out.

FIG. 6 shows a configuration of a volatilization apparatus comprising a storage container 14 provided with a packing or the like according to the present invention, an outer container 11 fitted above the storage container 14, and a sealing cap 20 fitted above the storage container 14. Is shown.
The sealing cap 20 is used by covering the storage container 14 from the production to the sale of the volatilization device, and the outer container 11 covers the storage container 14 after the user removes the sealing cap 20 from the storage container 14 at the time of use. It is used in the manner described above.

FIG. 7 illustrates the volatilization device in two states as shown in FIG. 6, (a) is before use (at the time of sale) of the volatilization device according to the present invention, and (b) is each longitudinal section showing the time of use. FIG. In FIG. 7A, 14 is a storage container, 15 is a liquid absorbing member, 17 is a hooked stopper, 19 is a packing, and 20 is a sealing cap.
In the volatilization device of the prior invention, the packing has been used in a normal way. In other words, since the packing is provided on the back side of the sealing cap and the opening of the storage container is closed with the sealing cap, the opening closes the opening, which serves to prevent liquid leakage before use (at the time of sale). Therefore, if the sealing cap was removed and discarded when the volatilization device was used, the packing was also discarded together with this.

However, the present invention is characterized in that the packing used for the sealing cap is not discarded but is effectively used for preventing odor leakage even during use.
In FIG. 7A, the volatilization device at the time of sale has a packing 19 placed on the flange 17b outside the annular portion 17a extending upward of the inner plug 17 with the flange, and this is extended to the back side of the sealing cap 20. It sells in the state pressed with the extended part piece 20a made. By doing so, the packing 19 worked to prevent liquid leakage.
7B, when the user removes the sealing cap 20, the packing 19 still remains on the hooked inner plug 17, so that the outer container 11 is covered instead of the sealing cap 20. As a result, the packing 19 is pressed at the lower end of the body inner cylinder 12b1 of the outer container 11 and the lower end of the wall 13b1 of the inner cylinder, so that the above-described effect of the present invention (preventing slight odor from being emitted when not in use). ) Will be demonstrated.

  The packing described in Patent Document 2 described above is used in the same manner as the prior invention, and serves to prevent liquid leakage before use (at the time of sale), and continues to be used after the start of use. There is no way of thinking.

Next, a rotating cap improved according to the present invention will be described with reference to FIG. FIG. 8 is a view for explaining a rotating cap improved according to the present invention. FIG. 8A is a longitudinal sectional view (A) and a perspective view (B) of the rotating cap according to the present invention, and FIG. It is the longitudinal cross-sectional view (I) and perspective view (B) of the rotation cap which concerns on.
First, in FIG. 8B of the prior invention, the rotation cap 13 ′ includes a dish-shaped rotation operation portion 13a and two half-cylindrical portions 13b1 projecting downward from the rotation operation portion 13a. Yes. Long openings 13s and 13t are opened in the axial direction between the two semi-cylindrical portions 13b1. As described above, since the two semi-cylindrical portions 13b1 are formed as cantilever supports from the rotation operation portion 13a, if a strong force is applied to the tip of the semi-cylindrical portion 13b1, it bends from its root (buckling). There was a risk. Therefore, it was not possible to strongly press the hook of the hooked stopper 17 '(FIG. 12).

However, in FIG. 8A according to the present invention, the rotation cap 13 includes a dish-like rotation operation portion 13a and two half-cylindrical portions 13b1 projecting downward from the rotation operation portion 13a. According to the present invention, the two semi-cylindrical portions 13b1 are connected to each other according to the present invention. Thus, the two semi-cylindrical portions 13b1 are connected to each other at the root by the connecting portion 13z. Even if a strong force is applied to the tip of the shape portion 13b1, the possibility of bending (buckling) from the root is eliminated. Therefore, according to the present invention, the packing 19 (FIG. 2) can be strongly pressed, and the airtightness during this time is increased. In addition, since there is no gap between the body inner cylinder 12b of the hollow body 12 and the wall 13b1 of the inner cylinder 13b at the time of weak setting by the connecting part 13z, a function of preventing odor leakage is also provided.

Furthermore, the hollow body part improved by this invention is demonstrated using FIG. FIG. 9 is a view for explaining a hollow body portion improved according to the present invention. FIG. 9A is a longitudinal sectional view of the hollow body portion according to the present invention, FIG. 3) is shown in a removed state.
In both figures, 12 is a hollow barrel according to the present invention, 12b1 is a barrel inner cylinder 12b1, 21 is an air intake hole provided in the back of the hollow barrel 12 (see FIG. 3), and in FIG. The decorative fitting 12m (FIG. 3) is an engaging portion for fitting into the hollow body portion 12, and is formed at three locations. 12q is a large opening provided on the front surface of the hollow body 12 and substantially matches the shape of the decorative fitting 12m. 12z is a rib formed according to the present invention, and connects the hollow body 12 and the body inner cylinder 12b1. In the prior invention (FIG. 12), this rib 12z was not provided, but the rib 12z provided according to the present invention increases the strength of the barrel inner cylinder 12b1, and even if the packing 19 is pressed strongly at the lower end of the barrel inner cylinder 12b1. There is no longer a risk of bending (buckling) from the root. Therefore, according to the present invention, the packing 19 (FIG. 2) can be strongly pressed, and the airtightness during this time is increased.

  In the above embodiment, the size of the opening is adjusted by relatively rotating the opening formed in each of the inner and outer double walls, but the present invention is not limited to this. Rather than being applied, it is also applicable to a type of volatilization device that adjusts the size of the opening by moving the opening of each of the inner and outer double walls relative to each other up and down. Needless to say, you can.

  As described above, according to the present invention, the packing is interposed between the flange portion of the hooked stopper and the distal end portion of the inner cylinder portion and the barrel inner tube portion. Even subtle smells no longer come out of the volatilization device. The volatilization effect of the active ingredient can be sustained for a long time.

  In addition, since the opening formed in the inner cylindrical portion ends before a predetermined distance from the root portion of the cylindrical portion, the axial length of the wall portion is shortened, so that the strength is increased, and accordingly, the flange of the hooked inner plug Even if the part is pushed strongly with this, it does not buckle, and a reliable sealing is guaranteed.

  In addition, since the inner cylinder part of the trunk part is provided with a rib that communicates with the trunk part, the axial strength of the inner cylinder part increases, so that it does not buckle even when the hook part of the hooked inner plug is pushed strongly. A certain sealing is guaranteed.
