Description

The present invention relates to a container used for a volatilizer that sucks up and volatilizes a chemical solution by a suction volatilizer, and a volatilizer.

A volatilizer is known in which a chemical solution such as a liquid aromatic drug is stored in a container, and the chemical solution is sucked up and volatilized by a rod-shaped suction volatilizer. Some of these types of volatilizers have a plurality of sucking volatilizers. Some of the wicking volatilizers are located inside the container and the rest are located outside through the opening of the container.

Further, the volatilizer of Patent Document 1 has a conical surface on the inner surface of the opening of the container so that the opening area becomes smaller in order to prevent the chemical solution in the container from flowing out through the opening of the container when the container falls. Is formed in.

Japanese Unexamined Patent Publication No. 2012-45246

When the opening area of the container is reduced as described above, there are the following problems. That is, as the opening area becomes smaller, the proportion of the sucking volatilizer in the opening becomes larger, so that the gap between the sucking volatilizer becomes smaller. In addition, a part of the chemical solution sucked up by the sucking volatilizer leaks from the upper end or the surface of the sucking volatilizer, travels along the surface of the sucking volatilizer, and falls downward. Therefore, there is a problem that the gap between the wicking volatilizers becomes smaller, so that the minute chemical solution flowing on the surface of the wicking volatiles accumulates in the opening and flows out to the outside of the container.

Further, even in a volatilizer in which the inner surface of the opening is not an inclined surface, the suction volatilizer comes into contact with the inner edge of the opening, so that a minute chemical solution flowing on the surface of the suction volatilizer is transmitted along the inner edge of the opening. There is a problem that it flows out of the container.

Therefore, an object of the present invention is to provide a container capable of preventing the chemical solution from flowing out to the outside, and a volatilizer having the container.

The container of the present invention is used for a volatilizer that sucks up a chemical solution by a rod-shaped suction volatilizer and volatilizes the chemical solution, and has an inner surface and an outer surface that define a space in which the chemical solution can be accommodated. The container is formed at a hole communicating the inside and the outside and an edge of the hole on the outer surface, and is a step portion surrounding the hole at a position lower than a portion of the outer surface around the hole. It includes an arranged bottom surface and a stepped portion having an inner surface arranged between the bottom surface and the peripheral portion of the hole on the outer surface. The hole is formed so that the wicking volatilizer having the maximum inclination angle with respect to the axis of the hole can contact the first ridge portion between the inner surface of the hole and the bottom surface of the hole. The angle formed by the plane of the first ridge portion that passes through the contact point with the suction volatilizer having the maximum inclination angle with respect to the axis of the hole and is orthogonal to the axis is α. Let β be the angle formed by the plane and the straight line passing through the contact portion and in contact with the second ridge portion between the inner side surface of the step portion and the peripheral portion of the outer surface of the step portion. Then, α> β.

According to the present invention, it is possible to provide a container capable of preventing the chemical solution from flowing out to the outside, and a volatilizer having the container.

It has a wicking volatilizer 60.
The container 20 has a sufficiently large opening capable of accommodating the chemical solution L and allowing a plurality of suction volatilizers 60 to be inserted. The sufficiently large opening referred to here means that a gap is secured between the plurality of suction volatilizers 60 arranged in the opening, and the chemical solution L that falls along the surface of the suction volatilizer 60 is formed. The size is such that it is not blocked and accumulated by the plurality of suction volatilizers 60. Further, the number of the plurality of sucking volatilizers 60 referred to here is a predetermined number of volatiles used for the volatilizer 10.

In the present embodiment, the container 20 is a container body 30, a lid member 40 detachably attached to the container body 30, and a removable inner plug 50 attached to the container 20 at the time of shipment of the volatilizer 10 (FIG. 5).

As shown in FIG. 2, the container main body 30 has a main body portion 31 and a neck portion 35 which is continuously formed on the main body portion 31 and to which the lid member 40 is detachably attached. The main body 31 is formed in a substantially rectangular parallelepiped shape as an example. The main body portion 31 has a bottom wall portion 32, a body portion 33, and an upper wall portion 34. The bottom wall portion 32 is formed in a substantially rectangular shape in a plan view.

The bottom wall portion 32 has a mounting surface 32a that comes into contact with the mounting portion when the volatilizer 10 is mounted on the mounting portion such as a desk. The mounting surface 32a is formed by at least a part of the lower surface 32b of the bottom wall portion 32. The mounting surface 32a is formed on a flat surface. In the present embodiment, the mounting surface 32a is formed by the peripheral edge portion of the lower surface 32b of the bottom wall portion 32 as an example.

The body portion 33 is formed on the peripheral edge of the bottom wall portion 32. The upper wall portion 34 is formed on the upper edge portion of the body portion 33.

The neck portion 35 is integrally formed with the upper wall portion 34 of the main body portion 31. The neck portion 35 is arranged on the center of the main body portion 31. The neck portion 35 is formed in a cylindrical shape as an example. The neck portion 35 communicates with the inside of the main body portion 31. The axis C of the neck portion 35 is orthogonal to the extension surface of the mounting surface 32a of the bottom wall portion 32 of the main body portion 31.

The upper surface 35a of the neck portion 35 is formed in a plane orthogonal to the axis C of the neck portion 35. A male screw 35b is formed on the peripheral surface of the neck portion 35. The inner diameter of the neck portion 35 is 15.5 mm as an example in the present embodiment. The container body 30 is formed of glass as a main material as an example in the present embodiment.

The lid member 40 is formed in a tubular shape having a wall portion at one end. In the present embodiment, the lid member 40 has a body portion 41 and an upper wall portion 42 formed at one end of the body portion 41. On the inner peripheral surface 41a of the body portion 41, a female screw 41b that can be screwed into the male screw 35b of the neck portion 35 is formed.

The upper surface 42a of the upper wall portion 42 is formed in a plane orthogonal to the axis C1 of the body portion 41. A hole 70 is formed in the upper wall portion 42. The hole 70 penetrates the upper wall portion 42. As shown in FIG. 1, the holes 70 are formed in a circle in one example in a plan view. Further, the hole 70 is formed in a shape having a constant cross section in the axial direction thereof. The hole 70 is arranged coaxially with the body portion 41. In this embodiment, the inner diameter of the hole 70 is larger than the inner diameter of the neck portion 35. The inner diameter of the hole 70 is 16.8 mm as an example in the present embodiment.

The lower surface 42c of the upper wall portion 42 is formed in a plane parallel to the axis C1 of the body portion 41. The upper wall portion 42 has a holding portion 42b capable of holding a part of the inner plug 50 between the upper wall portion 42 and the neck portion 35.

In the state where the lid member 40 is attached to the neck portion 35, the body portion 41 and the neck portion 35 of the lid member 40 are arranged coaxially. That is, the hole 70 is arranged coaxially with the inner peripheral surface 35d of the neck portion 35. Therefore, as shown in FIGS. 2 to 4, when the lid member 40 is attached to the neck portion 35, the inner peripheral surface 71 of the hole 70 is located radially outside the inner surface of the neck portion 35. Further, the upper surface 42a of the lid member 40 is parallel to the mounting surface 32a of the bottom wall portion 32 of the main body portion 31. Further, the lower surface 42c of the upper wall portion 42 of the lid member 40 comes into surface contact with the upper surface 35a of the neck portion 35.

Note that FIG. 2 shows an enlarged view of the hole 70 of the lid member 40, the step portion 80 described later, and the range F21 in the vicinity thereof. FIG. 3 shows an enlarged view of the hole 70, the stepped portion 80, and the range F31 in the vicinity thereof. FIG. 4 shows an enlarged view of the hole 70, the stepped portion 80, and the range F41 in the vicinity thereof.

As an example, the lid member 40 is made of any one of polyethylene, polypropylene, polyethylene terephthalate, acrylic resin, and metal. Further, at least the bottom surface 81 and the inner peripheral surface 82 of the stepped portion 80 described later of the lid member 40 are formed on smooth surfaces that can prevent the chemical solution L from being transmitted due to the capillary phenomenon.

A step portion 80 is formed on the edge of the hole 70 of the upper surface 42a of the lid member 40. The step portion 80 is formed in a predetermined range radially outward from the hole 70. Therefore, the step portion 80 is formed in an annular shape that is coaxial with the hole 70 in a plan view.

The step portion 80 has a bottom surface 81 and an inner peripheral surface 82. That is, the step portion 80 is formed in an L-shaped cross section by the bottom surface 81 and the inner peripheral surface 82. The bottom surface 81 is formed in a plane orthogonal to the axis C1 of the body portion 41 of the lid member 40. The inner peripheral surface 82 is formed on a surface parallel to the axis C1 of the body portion 41.

Next, the inner diameter of the hole 70 of the lid member 40, the depth of the stepped portion 80, and the width of the bottom surface 81 will be described. The hole 70 has an inner diameter at which the suction volatilizer 60 in the container 20 contacts at least the first ridge X between the inner peripheral surface 71 of the hole 70 and the bottom surface 81 of the stepped portion 80. .. The depth of the step portion 80 and the width of the bottom surface 81 are set based on the maximum inclination angle of the suction volatilizer 60 with respect to the axis C1 of the hole 70 in the state of being inserted into the container 20.

This will be described in detail. A part of the suction volatilizer 60 inserted into the container 20 through the hole 70 comes into contact with the first ridge X between the inner peripheral surface 71 and the bottom surface 81 of the hole 70 of the lid member 40. Further, the posture of the suction volatilizer 60 is maintained in the container 20 by contacting the lower end of the suction volatilizer 60 with the ridge R between the upper surface 32c of the bottom wall portion 32 and the inner surface 33a of the body portion 33. .. In the present embodiment, the first ridge X is formed with a cross section of approximately 90 degrees as an example. That is, the inner peripheral surface 71 and the bottom surface 81 are orthogonal to each other.

The posture of the wicking volatilizer 60 differs depending on the location of the container 20 where the wicking volatile body 60 comes into contact. 2 to 4 show an example of the posture of the suction volatilizer 60 according to the position where the suction volatilizer 60 of the container 20 comes into contact.

FIG. 2 shows a state in which the volatilizer 10 is cut along a cross section that passes through the axis C1 of the hole 70 and is parallel to the longitudinal direction of the axis C1 and the bottom wall portion 32 of the main body portion 31. In FIG. 2, the lower end of the suction volatilizer 60 is the center portion R1 of the main body portion 31 in the lateral direction of the ridge portion R between the upper surface 32c of the bottom wall portion 32 and the inner surface 33a of the body portion 33 (FIG. 1). Shows in contact with).

FIG. 3 shows a state in which the volatilizer 10 is cut along a cross section that passes through the axis C1 of the hole 70 and is parallel to the lateral direction of the axis C1 and the bottom wall portion 32. In FIG. 3, the lower end of the suction volatilizer 60 is the central portion R2 of the main body 31 in the longitudinal direction of the ridge R between the upper surface 32c of the bottom wall 32 and the inner surface 33a of the body 33 (FIG. 1). Shows).

In FIG. 4, the volatilizer 10 is cut along the axis C1 of the hole 70 and the two ridges G located diagonally opposite to each other and along the cross section parallel to the axis C1. Indicates the state. FIG. 4 shows a state in which the lower end of the suction volatilizer 60 is in contact with the ridge R3 (shown in FIG. 1) between the ridge G of the inner surface 33a of the body 33 and the upper surface 32c of the bottom wall 32. Is shown.

As shown in FIGS. 2 to 4, the inclination angle of the suction volatilizer 60 with respect to the axis C of the neck portion 35 differs depending on the location where the suction volatilizer 60 contacts the container 20. In the present embodiment, since the main body 31 of the container 20 has a rectangular parallelepiped shape, as shown in FIG. 4, the lower end of the sucking volatilizer 60 is the ridge of the inner surface 33a of the body 33. In a state of being in contact with the ridge portion R3 between the portion G and the upper surface 32c of the bottom wall portion 32, the inclination angle of the suction volatilizer 60 with respect to the axis C1 of the hole 70 is maximized.

As shown in FIG. 4, the depth of the step portion 80 and the width of the bottom surface 81 are the following conditions 1 and even in a state where the inclination angle of the suction volatilizer 60 with respect to the axis C1 of the hole 70 is maximum. , It is formed so as to satisfy the condition 2.

Condition 1: The suction volatilizer 60 comes into contact with the first ridge X between the inner peripheral surface 71 and the bottom surface 81 of the hole 70. In the present embodiment, as an example, the sucking volatilizer 60 is in contact with the first ridge X and is not in contact with the inner edge 35c of the opening of the neck 35 of the container body 30. However, it is not limited to this. The suction volatilizer 60 may come into contact with the first ridge X, and may also come into contact with the inner edge 35c of the opening of the neck 35.

Condition 2: The angle α is larger than the angle β. The angle α is an angle formed by the plane P passing through the contact point Q of the first ridge X with the sucking volatilizer 60 and orthogonal to the axis C1 of the hole 70 and the sucking volatilizer 60. The angle β is a straight line S and a plane P that pass through the contact point Q and come into contact with the second ridge Z between the inner peripheral surface 82 of the step portion 80 and the outer portion of the step portion 80 of the upper surface 42a. It is the angle that the eggplant makes. That is, the suction volatilizer 60 does not have to come into contact with the second ridge Z between the inner peripheral surface 82 of the step portion 80 and the outer portion of the step portion 80 of the upper surface 42a.

In this embodiment, the bottom surface 81 of the stepped portion 80 and the inner peripheral surface 71 of the hole 70 are orthogonal to each other. Therefore, in the present embodiment, the contact points Q where the first ridge portion X and the suction volatilizer 60 come into contact are the same points. Similarly, in the present embodiment, the inner peripheral surface 82 of the step portion 80 and the outer portion of the hole 70 of the upper surface 42a of the lid member 40 are orthogonal to each other. Therefore, in the present embodiment, the second ridge portion Z is the tip of a corner having a cross section of 90 between the inner peripheral surface 82 and the outer portion of the hole 70 on the upper surface 42a.

By forming the step portion 80 into a shape satisfying the above conditions 1 and 2, the plane P and the suction volatilizer 60 are arranged even when the suction volatilizer 60 is arranged as shown in FIGS. 2 and 3. The angle α formed by the joint is larger than the angle β formed by the plane P and the straight line S.

Further, the step portion 80 can prevent the chemical liquid L flowing down along the surface of the suction volatilizer 60 from flowing out beyond the step portion 80 and moving to the step portion 80 along the contact portion Q. It is preferably formed.

This will be described in detail. A part of the chemical solution L flowing downward along the surface of the suction volatilizer 60 travels from the contact portion Q of the first ridge portion X to the bottom surface 81 and the inner peripheral surface 82 of the step portion 80 to reach the step portion 80. Move in the circumferential direction. However, if the flow rate of the chemical solution L flowing from the contact portion Q to the stepped portion 80 is larger than the flow rate of the chemical solution L moving in the circumferential direction through the bottom surface 81 and the inner peripheral surface 82, the chemical solution L becomes the stepped portion. There is a possibility that it will flow out beyond 80. The chemical solution L is prevented from flowing out beyond the step portion 80 by increasing the depth of the step portion 80, the width of the bottom surface 81, and the gap Y between the suction volatilizer 60 and the bottom surface 81. be able to. Further, the depth of the step portion 80, the width of the bottom surface 81, and the gap Y for preventing the chemical solution L from flowing out beyond the step portion 80 can be obtained by, for example, an experiment.

As shown in FIG. 5, the inner plug 50 is detachably attached to the neck portion 35, and is formed so as to prevent the chemical solution L in the container 20 from flowing out through the hole 70 of the lid member 40 when attached. There is. The inner plug 50 has a main body portion 51 formed in a bottomed cylindrical shape and a flange portion 52 formed at the opening edge of the main body portion 51.

The main body portion 51 may be fitted into the neck portion 35 by, for example, tightening. Specifically, the outer diameter of the main body 51 is slightly larger than the inner diameter of the neck 35, for example. Therefore, when the main body 51 is press-fitted into the neck 35, the outer peripheral surface of the main body 51 comes into close contact with the inner peripheral surface 35d of the neck 35, so that the space between the hole 70 and the main body 51 is liquidtightly sealed.

The flange portion 52 is formed so as to be able to be arranged between the upper surface 35a of the neck portion 35 and the upper wall portion 42 of the lid member 40 in a state where the main body portion 51 is arranged in the neck portion 35. In the present embodiment, the radial width of the flange portion 52 is slightly narrower than the radial width of the upper surface 35a of the neck portion 35.

At the time of shipment of the volatilizer 10, the suction volatilizer 60 is separated from the container 20. Then, the lid member 40 is attached to the neck 35 in a state where the inner plug 50 is attached to the neck 35 (a state in which the main body 51 is inserted into the neck 35). The inner plug 50 is prevented from coming off from the container 20 by sandwiching the flange portion 52 between the upper surface 35a of the neck portion 35 and the upper wall portion 42 of the lid member 40.

The suction volatilizer 60 is formed in a rod shape. The suction volatilizer 60 is formed so that the chemical solution L in the container 20 can be sucked up by the capillary phenomenon. As an example, the wicking volatilizer 60 is formed of a synthetic resin such as polyester, reeds, rattan, or the like. In the present embodiment, the suction volatilizer 60 is formed in a columnar shape having a constant cross-sectional shape. In the present embodiment, the wicking volatilizer 60 is formed in a columnar shape as an example, and has a diameter of 3 mm as an example.

Next, the operation of the volatilizer 10 will be described. When using the volatilizer 10, the lid member 40 is first removed from the container 20. Next, the inner plug 50 is removed. Next, the lid member 40 is reattached to the neck portion 35 of the container 20. At this time, it is preferable to screw the lid member 40 to the neck portion 35 until the lower surface 42c of the upper wall portion of the lid member 40 is in close contact (surface contact) with the upper surface 35a of the neck portion 35. When the lower surface 42c comes into surface contact with the upper surface 35a, the surfaces are sealed. Next, a plurality of suction volatilizers 60 are inserted into the container 20 through the holes 70 of the lid member 40.

The plurality of sucking volatilizers 60 suck up the chemical solution L in the container 20. The chemical solution L sucked up by the suction volatilizer 60 volatilizes from the surface of the portion of the suction volatilizer 60 located outside the chemical solution L. The volatilized gas is diffused to the surroundings.

A part of the chemical solution L sucked up by the sucking volatilizer 60 leaks from the upper end and the surface of the sucking volatilizer 60, travels along the surface of the sucking volatilizer 60, and falls downward. A part of the chemical solution L flowing on the surface of the suction volatilizer 60 returns to the chemical solution L stored in the container body 30 of the container 20 as it is along the surface of the suction volatilizer 60. Further, a part of the chemical solution L that falls along the surface of the suction volatilizer 60 moves to the inner peripheral surface 71 of the hole 70 of the lid member 40 through the first ridge X, and the inner peripheral surface 71 and the neck portion. It returns to the chemical solution L stored in the container 20 along the inner peripheral surface 35d of the 35. Further, a part of the chemical solution L moves to the lid member 40 side along the first ridge portion X. The chemical solution L that has moved to the lid member 40 side collects in the step portion 80. The chemical solution L accumulated in the step portion 80 returns to the inside of the container 20 by volatilizing from the step portion 80 or falling into the container 20 from the step portion 80.

In the volatilizer 10 configured in this way, the chemical solution moved to the lid member 40 side along the first ridge X by forming the step portion 80 at the edge of the hole 70 of the upper surface 42a of the lid member 40. Since L can be stored in the stepped portion 80, it is possible to prevent the chemical solution L from flowing out of the container 20, or it is possible to reduce the amount of the chemical solution L flowing out to the outside.

Further, by forming the step portion 80 into an L-shaped cross section having the bottom surface 81 and the inner peripheral surface 82, the gap between the step portion 80 and the suction volatilizer 60 is formed between the suction volatilizer 60 and the step portion. Since there is a gap Y between the bottom surface 81 of the 80, this gap can be increased. Therefore, it is possible to prevent the chemical solution L from flowing out beyond the step portion 80.

Further, since the gap Y can be increased, the amount of the chemical solution L flowing out beyond the step portion 80 can be made substantially zero while suppressing the enlargement of the lid member 40 and the reduction of the opening area of the hole 70. ..

This effect will be specifically described. In order to make the amount of the chemical solution L flowing out beyond the step 80 to zero or substantially zero, the width of the bottom surface 81 should be increased, the depth of the step 80 should be deepened, and the suction volatilization should be achieved. It is effective to increase the gap Y between the body 60 and the surface of the stepped portion 80, at least one of them.

However, in order to increase the width of the bottom surface 81, it is necessary to increase the size of the lid member 40 in the radial direction or decrease the inner diameter of the hole 70, which increases the size of the lid member 40. Alternatively, the opening area of the hole 70 needs to be reduced. Even when the step portion 80 is deepened, it is necessary to increase the size of the lid member 40 because the upper wall portion 42 of the lid member 40 needs to be thickened.

However, as in the present embodiment, since the step portion 80 has the bottom surface 81, the gap between the suction volatilizer 60 and the surface of the step portion 80 is formed between the suction volatilizer 60 and the bottom surface 81. Since the gap Y can be set, it is possible to increase the gap Y.

Therefore, it is possible to prevent the lid member 40 from becoming large and the opening area of the hole 70 from being reduced while reducing the amount of the chemical solution L flowing out beyond the step portion 80 to zero or substantially zero. By suppressing the reduction in the opening area of the hole 70, it is possible to increase the gap between the suction volatilizers 60 in the hole 70. By increasing the gap between the suction volatilizers 60, the volatilization efficiency of the chemical solution L can be improved.

In the present embodiment, the container 20 has a lid member 40, and a hole 70 is formed in the lid member 40 as an opening, but the present invention is not limited to this. In another example, as shown in FIG. 6, the container 20 does not have to have the lid member 40. In this case, the step portion 80 is formed on the upper surface 35a of the neck portion 35 of the container body 30.

Further, in the present embodiment, the posture of the sucking volatilizer 60 inserted into the container 20 through the hole 70 is such that a part of the sucking volatilizer 60 comes into contact with the contact point Q of the first ridge X and sucks up. The lower end of the volatilizer 60 is held by contacting the ridge R between the upper surface 32c of the container body 30 and the inner surface 33a of the body 33. However, for example, as shown in FIG. 6, when the neck portion 35 is long, the posture of the suction volatilizer 60 in the container 20 is such that a part of the suction volatilizer 60 comes into contact with the inner edge of the opening and the suction volatilizer 60 is vaporized. A part of the body 60 is held by contacting the lower end 35e of the inner peripheral surface 35d of the neck 35, and the lower end of the suction volatilizer 60 is in contact with the upper surface 32c of the container body 30.

As described above, the posture of the suction volatilizer 60 in the state of being attached to the container 20 is determined by the shape of the container 20. Regardless of the shape of the container 20, the hole 70 and the stepped portion 80 are in a state where the inclination angle of the suction volatilizer 60 inserted in the container 20 with respect to the axis of the hole 70 is maximum, and the above-mentioned condition 1 And it may be formed in a shape satisfying the condition 2.

Further, in the present embodiment, the inner diameter of the hole 70 is larger than the inner diameter of the neck portion 35 of the container body 30. However, it is not limited to this. In another example, as shown in FIG. 7, the inner diameter of the hole 70 is the hole 70 and the step when the inclination angle of the suction volatilizer 60 mounted on the container 20 with respect to the axis C1 of the hole 70 is maximum. As long as the portion 80 has a shape satisfying the above-mentioned conditions 1 and 2, it may be the same as the inner diameter of the neck portion 35. That is, the inner peripheral surface of the neck portion 35 and the hole 70 may be arranged coaxially, and the inner diameter of the neck portion 35 and the inner diameter of the hole 70 may be the same. Alternatively, as shown by the alternate long and short dash line in FIG. 7, the inner diameter of the hole 70 may be smaller than the inner diameter of the neck portion 35. That is, the hole 70 and the inner peripheral surface 35d of the neck portion 35 may be arranged coaxially, and the inner diameter of the hole 70 may be smaller than the inner diameter of the neck portion 35.

Further, in the present embodiment, the bottom surface 81 of the step portion 80 is formed on a plane orthogonal to the axis C1 of the hole 70 of the lid member 40, but the present invention is not limited to this. In another example, the bottom surface 81 may be formed on a surface whose inner edge side is inclined so as to be located downward with respect to the outer edge side. In the present embodiment, as an example, the bottom surface 81 may be formed on a conical surface. Further, as shown in FIGS. 2 to 4, the bottom surface 81 is preferably formed on a linear surface whose inner edge side is located downward in the cut state. The conical surface is an example of this.

By forming the bottom surface 81 on the inclined surface in this way, the chemical solution L that has moved to the step portion 80 smoothly falls into the container body 30.

Further, in the present embodiment, the container main body 30 has a main body portion 31 and a neck portion 35, but is not limited thereto. In another example, the container 20 may be formed in a shape having a constant cross section, for example, a cylindrical shape or a square tubular shape. Alternatively, the container 20 may be spherical or box-shaped.

Further, in the present embodiment, the neck portion 35 is formed in a cylindrical shape, but the present invention is not limited to this. In another example, the neck portion 35 may be formed in each tubular shape such as a triangular tubular shape or a square tubular shape. In this case, the lid member 40 is formed in a rectangular shape as shown in FIGS. 8A and 8B in a plan view. Further, the hole 70 and the step portion 80 may be formed in a plane rectangular shape so as to match the inner surface of the square tubular neck portion 35 having a rectangular cross section. Similarly, even when the lid member 40 is not provided, the step portion 80 may be formed in a plane rectangle.

Further, in the present embodiment, the step portion 80 is formed on the upper surface 42a of the lid member 40. However, it is not limited to this. In another example, the step 80 may be composed of a neck 35 and a lid member 40, as shown in FIG. Specifically, by making the inner diameter of the hole 70 of the lid member 40 smaller than the inner diameter of the neck portion 35, a part of the upper surface 35a of the neck portion 35 and a part of the inner peripheral surface 71 of the hole 70 of the lid member 40. As a result, the step portion 80 is configured.
Further, in the present embodiment, the hole 70 is formed to have a circular cross section orthogonal to its axis (center line). However, it is not limited to this. In another example, the hole 70 may have a cross section orthogonal to its axis having a shape other than a circle, for example, a quadrangle. That is, in the present embodiment, the neck portion 35 is formed in a columnar shape in appearance, but the cross section orthogonal to the axis of the hole 70 may have a shape other than a circle.

Further, in the present embodiment, since the inner peripheral surface 71 of the hole 70 and the bottom surface 81 of the stepped portion 80 are orthogonal to each other, the plane P is the same plane as the bottom surface 81. However, the first ridge X between the inner peripheral surface 71 and the bottom surface 81 may be formed on a curved surface as shown in FIG. In this case, the contact point Q where the suction volatilizer 60 comes into contact with the first ridge portion X is one of the first ridge portions X. Further, in this case, the plane P is a plane that is parallel to the bottom surface 81 but is arranged at a position deviated from the bottom surface 81. Similarly, the second ridge Z between the inner peripheral surface 82 of the step 80 and the outer portion of the step 80 of the upper surface 42a may be formed on a curved surface. In this case, the straight line S comes into contact with the contact point Q and one of the second ridges Z.

The present invention is not limited to the above embodiment, and can be variously modified at the implementation stage without departing from the gist thereof. In addition, each embodiment may be carried out in combination as appropriate, and in that case, the combined effect can be obtained. Further, the above-described embodiment includes various inventions, and various inventions can be extracted by a combination selected from a plurality of disclosed constituent requirements. For example, even if some constituent requirements are deleted from all the constituent requirements shown in the embodiment, if the problem can be solved and the effect is obtained, the configuration in which the constituent requirements are deleted can be extracted as an invention.
