Description

  The present invention relates to a volatilization device that contains a chemical solution such as a fragrance and volatilizes the stored chemical solution.

  Volatilization devices are used to diffuse fragrances, deodorants and the like into the interior of a vehicle. The volatilization device stores a chemical solution such as a fragrance or a deodorant in the container, and sucks the stored chemical solution by a liquid-absorbing member disposed in the container. The chemical liquid sucked up by the liquid absorbing member volatilizes and exits from the opening of the container.

  Since the chemical liquid used in this type of volatilization apparatus has volatility, the pressure in the container increases when the amount of the chemical liquid vaporized in the container increases due to the influence of the ambient temperature. For this reason, the volatilization apparatus has a passage for ventilation that communicates the inside and the outside of the container in order to prevent the container from being damaged by the pressure increase in the container.

  There is known a technique in which a passage for ventilation is constituted by a groove formed in an outer peripheral surface of an inner plug that is arranged in a container and a liquid absorbing member is disposed inside the container, and an inner surface of the container covering the groove ( For example, see Patent Document 1.)

JP 2006-123766 A

  The above-described volatilization apparatus having a passage for ventilation has the following problems. That is, when the volatilization device falls, there is a problem that the chemical solution in the container leaks outside through the passage for ventilation. In particular, in a vehicle, there is a problem that the volatilization device easily falls or drops due to vibration during traveling. As a method to prevent chemicals from leaking outside through the passage when the volatilization device falls, the amount of chemicals in the volatilization device at the time of shipment is the amount at which chemicals do not leak outside through the passage when the volatilization device falls. It is conceivable to keep it at a minimum. However, this method is not preferable because the amount of the chemical solution at the time of shipment of the volatilization apparatus tends to decrease.

  Then, this invention aims at providing the volatilization apparatus which can increase the quantity of a chemical | medical solution, preventing that a chemical | medical solution leaks outside even if it falls.

  In order to solve the above problems and achieve the object, the volatilization apparatus of the present invention is configured as follows. The volatilization apparatus according to one aspect of the present invention includes at least a bottomed cylindrical container, and is provided in the outer body defining the outer shell, the liquid-absorbing member disposed in the container, and the outer shell, A clip projecting outward from the outer peripheral surface of the outer shell, and a passage portion formed in the container and communicating between the inside and the outside of the container, the passage portion sandwiching the axis of the container Arranged at any position in the axial direction of the container on the opposite side of the clip

In the present embodiment, the outer peripheral surface 25 of the main body 24 is an outer peripheral surface that is the outermost shell of the outer shell 5 of the volatilization device 10. As will be described later, the outer peripheral surface that is the outermost shell of the outer body 5 is an outer peripheral surface that contacts the flat surface 1 on which the volatilization device 10 is placed when the volatilization device 10 falls.

  The outer peripheral surface 25 has a first curved surface portion 26 and a first flat surface portion 27 formed in an arc shape. The first curved surface portion 26 is formed in an arcuate curved surface centering on an extension line of the axis C <b> 1 of the neck portion 21. That is, the first curved surface portion 26 has a cross section orthogonal to the extension line of the axis of the neck portion 21 formed in an arc centered on the extension line. In the present embodiment, a line including the axis C1 of the neck 21 and an extension of the axis C is defined as a first reference line L1. The first curved surface portion 26 is formed in a range of 180 degrees or more around the first reference line L1. In this embodiment, the 1st curved surface part 26 is formed in the range of 300 degree | times around the 1st reference line L1, for example.

  The first plane portion 27 is formed in a plane parallel to the first reference line L1. As shown in FIG. 2, the bottom surface 29a of the bottom wall portion 28 of the main body portion 24 is formed in a plane orthogonal to the first reference line L1.

  The main body 24 configured in this manner is arranged such that the axis when the cross section of the outer peripheral surface 25 is a circle, that is, the center of curvature of the first curved surface portion 26 is arranged on the first reference line L1. . In other words, it is coaxial.

  The outer peripheral surface 22a of the flange 22 has the 2nd curved surface part 22b and the 2nd plane part 22c, as shown in FIG. The second curved surface portion 22b is formed in a curved surface having a circular section in the center with the axis C1 of the neck portion 21 as the center. The diameter of the second curved surface portion 22 b is smaller than the diameter of the first curved surface portion 26.

  As shown in FIG. 3, the second curved surface portion 22 b is formed in a range facing the first curved surface portion 26 in the radial direction when viewed in the axial direction of the neck portion 21. The second plane portion 22 c is formed in a plane parallel to the axis C <b> 1 of the neck portion 21. As shown in FIG. 3, the second flat surface portion 22 c is formed in a range facing the first flat surface portion 27 in the radial direction when viewed in the axial direction of the neck portion 21.

  As shown in FIGS. 1 and 2, the cap 30 is formed in a cylindrical shape. Specifically, the cap 30 has a peripheral wall portion 31 and an upper wall portion 32. A female screw that can be screwed into the neck portion 21 is formed in a range from the opening end of the inner peripheral surface 33 of the peripheral wall portion 31 to the midway portion in the axial direction. A plurality of groove portions 34 extending in the axial direction are formed on the outer peripheral surface of the peripheral wall portion 31. The plurality of groove portions 34 are spaced apart in the circumferential direction. A plurality of volatilization ports 35 are formed in part of the peripheral wall part 31 and part of the upper wall part 32. The plurality of volatilization openings 35 penetrate a part of the peripheral wall part 31 and a part of the upper wall part 32.

  As shown in FIG.2 and FIG.4, the inner stopper 40 is formed in the cylinder shape which can arrange | position the liquid absorption member 60 inside. The inner plug 40 is arranged such that its axis C2 is coaxial with the first reference line L1. Specifically, the inner plug 40 has a large-diameter portion 41 that can be fixed in the opening of the container 20, and a small-diameter portion 42 that is formed continuously with the large-diameter portion 41.

  The large-diameter portion 41 is disposed in the neck portion 21 coaxially with the neck portion 21 and is formed so as to be fixed in the circumferential direction. Specifically, the large diameter portion 41 is formed in a bottomed cylindrical shape having a diameter slightly smaller than the inner diameter of the neck portion 21. The large-diameter portion 41 has a flange 43 that is in contact with the opening edge of the neck portion 21 in the axial direction at the opening edge portion. The large diameter portion 41 has a length shorter than the length of the neck portion 21 in the axial direction. The large-diameter portion 41 is a length in which the lower end is disposed above the flange 22 of the container 20 in a state where the inner plug 40 is attached to the container 20, that is, in a state where the flange 43 is in contact with the upper end opening of the neck portion 21. Have

  On the outer peripheral surface 41a of the large-diameter portion 41, a convex portion 44 that protrudes radially outward from the outer peripheral surface 41a is formed. The convex portion 44 is formed in an annular shape. For example, a plurality of convex portions 44 are formed. When the inner plug 40 is disposed in the neck portion 21, the convex portion 44 is liquid-tight between the outer peripheral surface of the large diameter portion 41 and the inner peripheral surface of the neck portion 21 by contacting the inner peripheral surface of the neck portion 21. It is formed so that it can be sealed. Moreover, the convex part 44 is formed so that the large diameter part 41 can be fitted in the neck part 21 so that the circumferential direction can be fixed in the neck part 21. As described above, the large-diameter portion 41 is an interference fit in the neck portion 21 by the convex portion 44, and is fitted in the neck portion 21 and fixed in the circumferential direction. For this reason, the inner plug 40 is prevented from rotating in the container 20.

  As shown in FIG. 5, a hole 47 is formed in the bottom wall portion 45 of the large diameter portion 41 on the radially outer side than the small diameter portion 42. The hole 47 is an example of the passage portion of the present invention. The hole 47 penetrates the bottom wall portion 45 in the axial direction of the inner plug 40. The hole 47 is formed in a rectangular shape such as a rectangle, for example, in a plan view as viewed in the axial direction of the inner plug 40.

  The hole 47 has a surface 47 a on the axial line side of the inner plug 40. The edge arrange | positioned at the bottom face 45a of the bottom wall part 45 of the surface 47a is arrange | positioned in the edge part between the bottom face 45a of the bottom wall part 45 and the outer peripheral surface of the small diameter part 42 in this embodiment. For this reason, the surface 47 a is formed in a curved surface along the ridge between the bottom surface 45 a and the outer peripheral surface of the small diameter portion 42.

  As shown in FIGS. 2, 4, and 6, the small diameter portion 42 protrudes in the axial direction from the bottom surface 45 a of the bottom wall portion 45 of the large diameter portion 41. The small-diameter portion 42 is formed in a cylindrical shape that gradually decreases in diameter as its outer peripheral surface 42a and inner peripheral surface 42b go to the tip. The small diameter portion 42 is formed coaxially with the large diameter portion 41.

  The diameter of the inner peripheral surface 42 b at the end of the small diameter portion 42 on the large diameter portion 41 side is set to a diameter having a slight gap with the liquid absorbing member 60. The diameter of the inner peripheral surface 42 b of the lower end 42 c of the small diameter portion 42 is set to a diameter that can contact the liquid absorbing member 60 and hold the liquid absorbing member 60. The holding here does not have a holding force to prevent the lower end of the liquid absorbing member 60 from coming out of the lower end 42c of the small diameter portion 42 when the liquid absorbing member 60 is inserted into the inner plug 40.

  The small diameter portion 42 is in a state where the inner plug 40 is attached to the container 20 as shown in FIG. 2, that is, in a state where the flange 43 is in contact with the open end of the container 20, and at least the lower end 42 c is in the axial direction of the container 20. It has a length arranged below the intermediate position. The axial length of the container 20 is the length from the upper end of the neck portion 21 to the upper surface 29b of the bottom wall portion 28. The small-diameter portion 42 preferably has a length that does not contact the upper surface 29b of the bottom wall portion 28 of the main body portion 24 and is disposed at a position close to the upper surface 29b.

  Further, the inner plug 40 has a surrounding wall portion 50 formed continuously from a part of the outer peripheral surface 42 a of the small diameter portion 42 and a part of the bottom surface 45 a of the bottom wall portion 45 of the large diameter portion 41. As shown in FIG. 4, the surrounding wall portion 50 has a groove 55 communicating with the hole 47 and having an opening in the radial direction of the inner plug 40. The shape of the surrounding wall portion 50 as viewed in the radial direction of the inner plug 40 is formed in a U shape that opens toward the bottom surface 45 a of the bottom wall portion 45. Both ends of the surrounding wall portion 50 are connected to the bottom surface 45 a of the bottom wall portion 45.

  In this embodiment, the enclosure wall 50 is a plate-like first wall 51 and second wall 52 that are parallel to the axial direction of the inner plug 40, and a plate that is orthogonal to the axial direction of the inner plug 40. The third wall portion 53 is provided. One end 51 a of the first wall portion 51 and one end 52 a of the second wall portion 52 are connected to the bottom surface 45 a of the bottom wall portion 45. More specifically, the one end 51 a is connected to the edge of the hole 47. One end 52 a is connected to the edge of the hole 47. The first wall portion 51 and the second wall portion 52 are formed in parallel. The third wall portion 53 is connected to the other end of the first wall portion 51 and the other end of the second wall portion 52.

  The length in the width direction of the groove 55, that is, the length between the inner surface 51 b of the first wall portion 51 and the inner surface 52 b of the second wall portion 52 is the length of the groove 55, that is, in the bottom surface 45 a of the hole 47. Shorter than the length between the opening and the inner surface 53a of the third wall portion 53. The heights of the first wall 51, the second wall 52, and the third wall 53 from one plane passing through the axis C2 of the inner plug 40 and parallel to the axis C2 are the same. In addition, the radially outer surface 47 b of the hole 47 has a height 51 c in the height direction of the first wall 51, a height 52 c in the height direction of the second wall 52, and a height of the third wall 53. It arrange | positions in the plane which arrange | positions the front-end | tip 53c.

  Further, the enclosure wall 50 is formed so that the chemical liquid does not reach the hole 47 through the inside of the groove 55 due to surface tension when the volatilization device 10 falls. Specifically, the surrounding wall portion 50 has a length between the inner surface 51b of the first wall portion 51 and the inner surface 52b of the second wall portion 52 and the bottom surface of the bottom wall portion 45 so that surface tension acts. The length between 45a and the inner surface 53a of the third wall 53 and the depth of the groove 55 are determined. Further, the surrounding wall portion 50 is formed in consideration so that no chemical solution remains in the opening of the groove 55. Specifically, for example, even if the chemical solution is immersed in the opening of the groove 55 because the volatilization device 10 falls, for example, when the posture of the volatilization device 10 is returned, that is, the inner plug When the axial direction of 40 is parallel to the direction in which gravity acts, the chemical liquid adhering to the opening of the groove 55 falls due to gravity, and no chemical liquid remains in the opening of the groove 55. The enclosure wall 50 is formed so that this action occurs. In order to produce this action, the opening of the groove 55 is formed in a rectangular shape that is long in the axial direction of the inner plug 40. The shape of the groove 55 can be obtained by experiment.

  As shown in FIG. 2, the liquid absorbing member 60 is formed in a rod shape whose cross section is, for example, a circle. The liquid absorbing member 60 is disposed in the inner plug 40. The liquid absorbing member 60 has a size that is held by the lower end 42 c of the small diameter portion 42 of the inner plug 40. The liquid absorbing member 60 has such a length that its upper end is located above the upper end of the inner plug 40 when its lower end contacts the upper surface 29 b of the bottom wall portion 28 of the container 20.

  The middle cap 70 is detachably formed in the opening of the large diameter portion 41 of the middle plug 40. The middle cap 70 is formed to be able to liquid-tightly close the opening of the large diameter portion 41 when attached to the opening of the large diameter portion 41. Specifically, the middle cap 70 has a bottomed cylindrical middle cap body 71 fitted into the large diameter portion 41, and a flange 73 formed on the outer peripheral surface of the middle cap body 71. The middle cap 70 is inserted into the large diameter portion 41 until the position where the flange 73 contacts the upper end of the large diameter portion 41. The middle cap 70 is attached at the time of shipment of the volatilization apparatus 10, and is removed at the time of use.

  The clip 90 is configured such that the volatilization device 10 can be attached to the attachment portion by sandwiching an attachment portion such as a louver provided at the air outlet of the air conditioner. In this embodiment, the clip 90 is configured to be detachable from the container 20. The clip 90 is attached to the container 20 via a ring member 80 that can be attached to and detached from the container 20.

  As shown in FIGS. 2 and 7, the ring member 80 includes a ring portion 82 and a connecting portion 83 that is integrally formed with the ring portion 82 and to which the clip 90 is detachably connected. The ring part 82 has a hole 84 in which the neck part 21 can be arranged inside, and is formed in an annular shape that can be placed on the flange 22 of the neck part 21. The hole 84 has a slightly larger diameter than the male screw of the neck portion 21. Further, as shown in FIG. 2, the ring portion 82 has a smaller diameter on the outer peripheral surface than the outer peripheral surface 25 of the main body portion 24 of the container 20. That is, the outer peripheral surface of the ring portion 82 does not become an outer peripheral surface that defines the outermost shell of the outer shell 5. In addition, since the connection part 83 functions as a part of the clip 90 when the clip 90 is connected, in this embodiment, it does not constitute a part of the outer body 5.

  The connecting portion 83 is formed on a part of the outer peripheral portion of the ring portion 82. The external appearance of the connection part 83 is formed in a rectangular parallelepiped shape, for example. Specifically, the connecting portion 83 has a peripheral wall portion 85 and an upper wall portion 86. In addition, the connecting portion 83 is provided with an accommodating portion 89 for accommodating a later-described accommodated portion 93 of the clip 90.

  The accommodating portion 89 opens at the lower end of the connecting portion 83. The surface of the connecting portion 83 on the axis line side of the hole 84 of the ring portion 82 has a third flat portion 87 as shown in FIG. In the present embodiment, the third plane portion 87 is formed in the housing portion 89. The third plane part 87 is formed in a plane parallel to the extension line of the axis of the ring part 82. In the present embodiment, a line including the axis of the ring portion 82 and an extension of the axis is defined as the second reference line L2.

  The upper part of the third plane part 87 faces the second plane part 22 c of the flange 22 of the neck part 21. The lower part of the third plane part 87 is in surface contact with the first plane part 27. The third planar portion 87 is in contact with the first planar portion 27 so that the ring member 80 can be prevented from rotating around the neck portion 21.

  A groove 88 communicating with the inside of the connecting portion 83 is formed in the wall portion of the peripheral wall portion 85 opposite to the third flat surface portion 87. The groove 88 extends in the axial direction of the ring portion 82 and communicates with the opening at the lower end of the connecting portion 83. The center of the groove 88 in the width direction W is disposed on a plane parallel to the second reference line L2. The width direction W is a direction orthogonal to the axial direction of the hole 84 of the ring portion 82 and is parallel to the third plane portion 87.

  As shown in FIG. 8, the clip 90 includes a sandwiching portion 91 formed in a plane U shape, a cylindrical neck portion 92 formed at one end of the sandwiching portion 91, and a receiving portion formed at one end of the neck portion 92. 93.

  The sandwiching portion 91 has a base portion 94 and a pair of plate-like arm portions 95. The pair of arm portions 95 are formed integrally with the base portion 94. The pair of arm portions 95 are arranged to face each other with a gap. The pair of arm portions 95 are formed so that the length between the pair of arm portions 95 becomes shorter from the base portion 94 side toward the distal end side. The sandwiching portion 91 configured as described above has elasticity, and is formed so as to be able to sandwich an attachment portion such as a louver provided at the air blowing port of the air conditioner between the pair of arm portions 95.

  The neck portion 92 is formed integrally with a portion of the base portion 94 opposite to the arm portion 95. The neck portion 92 is formed so as to be disposed in the groove 88 of the connecting portion 83. The accommodated portion 93 is formed so as to be accommodated in the accommodating portion 89 through the opening at the lower end of the connecting portion 83. The accommodated portion 93 is formed in a plate shape orthogonal to the axial direction of the neck portion 92. As shown in FIG. 9, the accommodated portion 93 is formed in a polygonal shape having a plurality of flat portions 93b on the outer peripheral surface 93a.

  The accommodated portion 93 is fixed in the connecting portion 83 when the flat surface portion 93 b of the outer peripheral surface 93 a is in surface contact with the inner surface of the accommodating portion 89. In the present embodiment, the accommodated portion 93 has a regular octagonal front shape. The accommodated portion 93 is formed in an octagonal shape when viewed from the front, so that the clip 90 has a posture in which at least the direction in which the pair of arm portions 95 are aligned is perpendicular to the second reference line L2, or a pair The arm portions 95 can be held by the connecting portion 83 in such a posture that the direction in which the arm portions 95 are aligned is the axial direction of the hole 84 of the ring portion 82.

  Since the clip 90 configured in this way has a pair of arm portions 95 having the same shape, the clip 90 is formed in a symmetrical shape. Further, when the clip 90 is attached to the container 20 via the ring member 80, the clip 90 protrudes in the radial direction from the outer peripheral surface of the container 20. Even if the clip 90 is fixed in any posture by the accommodated portion 93, the center in the width direction W is aligned with the center in the width direction W of the connecting portion 83 of the ring member 80 in the radial direction of the container 20. . Further, regardless of the posture in which the clip 90 is fixed by the accommodated portion 93, the length of the clip 90 in the width direction W is smaller than the diameter of the first curved surface portion 26 of the outer peripheral surface 25 of the container 20. In addition, the width direction of the clip 90 referred to in the present invention is a direction orthogonal to the axial direction of the container 20 and orthogonal to the protruding direction of the clip 90 from the outer body 5. Become.

  For this reason, as shown in FIG. 10, when the volatilization device 10 is placed so that the outer peripheral surface 25 of the main body 24 of the container 20 is brought into contact with the horizontal plane 1, the weight of the clip 90 and the first of the outer peripheral surface 25. When the first curved surface portion 26 is an arcuate curved surface, the clamping portion 91 of the clip 90 rotates to a position where it contacts the flat surface 1. In FIG. 10, the cap 30 and the liquid absorbing member 60 are omitted for explanation.

  The position in the circumferential direction in the container 20 of the inner plug 40 of the volatilization apparatus 10 configured as described above will be specifically described. The inner plug 40 is fixed at a position X1 in the circumferential direction of the neck portion 21. As shown in FIG. 10, the position X1 is a position where the hole 47 passes through the axis C2 of the inner plug 40 and the center C3 in the width direction W of the clip 90 and is arranged on a plane P1 parallel to the axis C2. In the present embodiment, the center 47c of the hole 47 is disposed on the plane P1. That is, the hole 47 is disposed on the opposite side of the clip 90.

  By disposing the inner plug 40 at the position X1, when the volatilization device 10 is placed on the plane 1 as shown in FIG. 10, the center 47c of the hole 47 is disposed above the axis C2. In the present embodiment, the hole 47 has a size such that the entire hole 47 is located above the axis C2.

  Next, an example of the assembly process of the volatilization apparatus 10 will be described. First, a chemical solution is stored in the container 20. Next, the inner plug 40 is inserted into the container 20. At this time, the inner plug 40 is disposed at a circumferential position X1 in the container 20. The operator can grasp the circumferential position of the hole 47 by checking the surrounding wall portion 50 of the inner plug 40, so that the inner plug 40 can be smoothly arranged at the position X1. The position of the inner plug 40 is fixed in the circumferential direction when the large-diameter portion 41 is fitted into the neck portion 21.

  Next, the liquid absorbing member 60 is inserted into the inner plug 40. Next, the clip 90 is attached to the ring member 80. Specifically, the accommodated portion 93 of the clip 90 is accommodated in the accommodating portion 89 of the connecting portion 83 of the ring member 80. Next, the ring member 80 to which the clip 90 is attached is attached to the neck portion 21 of the container 20. At this time, the third plane portion 87 is brought into surface contact with the first plane portion 27. Next, the middle cap 70 is inserted into the large diameter portion 41 of the middle plug 40. Next, the cap 30 is screwed into the neck portion 21 of the container 20 and fixed. When the cap 30 is screwed, the ring member 80 is sandwiched between the flange 22 and the cap 30.

  Next, the effect | action of the volatilization apparatus 10 is demonstrated. The volatilization apparatus 10 prevents the chemical solution from going out of the container 20 by the middle cap 70 before use. The volatilization device 10 has the middle cap 70 removed when used. When the middle cap 70 is removed, the liquid sucked up by the liquid absorbing member 60 and the chemical solution volatilized in the large diameter portion 41 passes through the volatilization port 35 of the cap 30 and goes out to the surroundings.

  When the volatilization amount of the chemical solution in the container 20 increases due to the influence of the ambient temperature, the chemical solution volatilized in the container 20 passes through the groove 55 and the hole 47 and exits into the large diameter portion 41 of the inner plug 40. The chemical solution that has volatilized in the inner plug 40 passes through the volatilization port 35 and goes out of the volatilization apparatus 10. For this reason, since the pressure in the container 20 is prevented from becoming excessively high, the chemical liquid is prevented from being ejected to the outside through the liquid absorbing member 60 due to the internal pressure.

  In the volatilization device 10 configured in this manner, the clip 90 is provided in the container 20 and the volatilization device 10 is shown in FIG. 10 when the volatilization device 10 falls by placing the hole 47 at the position X1. In this way, the clip 90 tends to come into contact with the placement surface. In the posture shown in FIG. 10, the hole 47 is disposed above the axis C <b> 1 of the inner plug 40. If the liquid level when the volatilization apparatus 10 falls is below the hole 47, the chemical liquid does not leak outside through the hole 47. As described above, the amount of the chemical solution in the container 20 can be increased by arranging the hole 47 when the volatilization device 10 is toppled at a position higher than the axis C1 of the inner plug 40 as shown in FIG. it can. That is, the amount of the chemical solution at the time of shipment of the volatilization device 10, in other words, the amount of the chemical solution before the volatilization device 10 is used can be increased.

  Furthermore, since the outer peripheral surface 25 of the main body 24 of the container 20 has the first curved surface portion 26, the volatilization apparatus 10 is brought into contact with the mounting surface by the first curved surface portion 26 as shown in FIG. It can be rotated until For this reason, even if the volatilization device 10 falls, the hole 47 is disposed above the axis C1 of the inner plug 40 as shown in FIG. Furthermore, even if the container 20 rotates in any direction around the first reference line L1, the hole 47 is disposed above the axis C1.

  Furthermore, since the hole 47 is formed in the bottom wall part 45 of the large diameter part 41, even if the volatilization apparatus 10 falls, it is above the position which becomes the lower end of the outer peripheral surface 41a of the large diameter part 41 of the inner plug 40. Located in. For this reason, the chemical liquid in the container 20 is difficult to reach the hole 47, so that the chemical liquid is prevented from leaking out of the container 20.

  Furthermore, even if the volatilization device 10 falls, the enclosure wall 50 prevents the chemical solution in the container 20 from reaching the hole 47, so that the leakage from the container 20 through the hole 47 is prevented. Furthermore, the surrounding wall portion 50 is formed so as to prevent the chemical liquid from entering the groove 55 due to surface tension. For this reason, even if the opening of the groove 55 faces downward and the liquid level of the chemical liquid is positioned above the opening of the groove 55, the chemical liquid in the container 20 is prevented from leaking to the outside. . For example, when the volatilization device 10 falls, the volatilization device 10 rotates until the clip 90 contacts the plane 1. During this rotation, the volatilization apparatus 10 may be in a posture in which the opening of the groove 55 faces downward, but the chemical liquid is prevented from entering the groove 55 due to the surface tension as described above. . Furthermore, the shape of the opening of the groove 55 is such that even if the opening of the groove 55 is immersed in the chemical solution because the volatilization device 10 falls, for example, when the posture of the volatilization device 10 is returned, that is, the inner plug 40. When the axial direction is parallel to the vertical direction, the chemical solution is formed so as not to remain in the opening of the groove 55. For this reason, even if the pressure in the container 20 becomes high, the chemical liquid adhering to the opening of the groove 55 is not ejected to the outside.

  Further, the small-diameter portion 42 has such a length that the lower end 42c is disposed below the intermediate position in the axial direction of the container 20 in a state where the inner plug 40 is attached to the container 20. For this reason, even if the volatilization apparatus 10 falls and the chemical solution in the container 20 enters the inner plug 40 through the lower end 42 c of the small diameter portion 42, the penetrated chemical solution enters the opening that is the other end of the inner plug 40. Since the route to reach can be lengthened, the chemical liquid can be prevented from leaking out of the container 20.

  Furthermore, since the surrounding wall part 50 becomes a mark, the workability of the work of attaching the inner plug 40 to the container 20 is improved.

  Moreover, the length of the small diameter part 42 can be lengthened by having the length by which the small diameter part 42 is arrange | positioned in the position close | similar to the bottom wall part 48 of the container 20 like the small diameter part 42 like this embodiment. it can.

  In addition, in this embodiment, although the clip 90 is comprised so that attachment or detachment to the container 20 is carried out, it is not limited to this. The clip 90 may be formed integrally with the container 20. Moreover, in this embodiment, although the outer peripheral surface 25 of the main-body part 24 of the container 20 is formed in the curved surface in which a part becomes a circular arc surface, it is not limited to this. In another example, the outer peripheral surface 25 may have a circular cross section. That is, the main body 24 may be formed in a bottomed cylindrical shape. Even in this case, even if the volatilization device 10 falls, the volatilization device 10 rotates until the holding portion 91 of the clip 90 contacts the plane 1 due to the weight of the outer peripheral surface 25 and the clip 90.

  In the present embodiment, the ring member 80 is prevented from rotating around the neck portion 21 due to the surface contact between the third plane portion 87 and the first plane portion 27. However, the rotation preventing structure of the ring member 80 is not limited to being achieved by this surface contact. The rotation of the ring member 80 may be prevented by other structures.

  Moreover, in this embodiment, although the clip 90 was attached to the container 20 via the ring member 80, it is not limited to this. In another example, the clip 90 may be formed to be detachable from the container 20 without using other members. Alternatively, the clip 90 may be fixed to the container 20 and formed integrally with the container 20.

  In the present embodiment, the first curved surface portion 26 is an example of a curved surface formed on the opposite side of the clip 90, but is not limited to a curved surface having a circular cross section. In another example, the volatilization device 10 is rotated so that the fallen volatilization device 10 has a posture in which the clip 90 contacts the plane 1 as shown in FIG. Any curved surface may be used.

  In the present embodiment, the hole 47 which is an example of the passage portion is formed in the inner plug 40. This is an example in which the passage portion is formed in the container. In another example, the passage portion may be formed in the peripheral wall portion of the container 20. This is also an example in which the passage portion is formed in the container.

  In the present embodiment, the hole 47 is disposed on the opposite side in the radial direction of the clip 90 across the axis of the container 20 as shown in FIG. This position is an example of any position in the axial direction of the container 20 opposite to the clip 90 across the axis of the container 20. In another example, the passage portion having the same function as that of the hole 47 may be formed in the peripheral wall portion of the large-diameter portion 41 and disposed at a position away from the clip 90 in the axial direction of the container 20. In this case, the passage portion is not formed only by the inner plug 40, but may be constituted by the inner surface and the outer peripheral surface between the inner surface of the container 20 and the outer peripheral surface of the inner plug 40, for example. As an example of this, the groove extending in the axial direction of the container 20 formed on the inner peripheral surface of the neck portion 21 and the axial direction of the container 20 formed on the outer peripheral surface of the large-diameter portion 41 of the inner plug 40 are used. The groove may be formed by being combined with each other.

  In the present embodiment, the outer body 5 of the volatilization apparatus 10 has a cap 30. The cap 30 is attached to the container 20 during normal use of the volatilization apparatus 10. In this embodiment, the outer peripheral surface of the cap 30 is formed in a curved surface having a substantially circular cross section, but is smaller than the diameter of the first curved surface portion 26 of the outer peripheral surface 25 of the main body portion 24. For this reason, the outer peripheral surface 25 is the outermost peripheral surface. That is, even if the volatilization device 10 falls, the volatilization device 10 is rolled by the first curved surface portion 26 with the outer peripheral surface 25 contacting the plane 1. As another example, for example, when the outer peripheral surface of the cap 30 is the outermost peripheral surface of the outer shell 5, that is, when the volatilization device 10 is viewed in the axial direction, the outer peripheral surface of the cap 30 is When the outer peripheral surface of the cap 30 contacts the plane 1 when the volatilization device 10 falls, the volatilization device 10 is placed in the container 20. When viewed in the axial direction, at least the portion of the outer peripheral surface of the cap 30 that is the outermost shell on the side opposite to the clip 90 is formed into a curved surface, so that the same effect as in this embodiment can be obtained. Similarly, in this embodiment, the ring member 80 also constitutes a part of the outer body 5. For example, when the ring portion 82 of the ring member 80 is an outer peripheral surface in which the outer peripheral surface of the outer shell 5 is the outermost shell of the outer shell 5, at least a portion of the outer peripheral surface of the ring portion 82 that is the outermost shell opposite to the clip 90 Is formed in a curved surface, the same effect as this embodiment can be obtained. In the present embodiment, the outer body 5 includes a cap 30 in addition to the container 20 as an example. However, it is not limited to this. For example, the volatilization device 10 may not include the cap 30 and the outer body 5 may be configured only from the container 20. As described above, the outer body 5 has a configuration including only the container 20 or a configuration having other members such as the cap 30 in addition to the container 20 by the volatilization device.
