[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-76783 Summary of the Invention [Problem to be solved by the invention]

[0004] In the conventional volatilization device described above, the volatilization material is supported near the top wall of the cap by a support portion provided on the inner peripheral surface of the peripheral wall of the cap. The drug container and cap are made of, for example, polyethylene terephthalate (PET), and the volatilizer may be made of any material that allows the drug to be absorbed, such as paper or felt. However, after using the volatilizer, the user must separate and dispose of the components made of these different materials, and therefore must remove the volatilizer from the cap. However, in conventional volatilization devices, the volatilizer is supported by a support part near the top wall of the cap, making it difficult to remove, and because the volatilizer is impregnated with the remaining drug, grabbing the volatilizer to remove it would stain your hands. The present invention has been made in consideration of the above circumstances, and aims to provide a volatile substance support cap that is advantageous in that it allows the volatile substance to be easily removed without staining the hands with chemicals when disposing of it after use. [Means for solving the problem]

In one embodiment of the present invention, the inner surface of the peripheral wall portion has a width W1 and a length L1 perpendicular to the width W1, and both side portions of the peripheral wall portion that face the inner surface of the peripheral wall portion in the width direction are convex in directions away from each other, with the central portion in the length direction being formed by curved surfaces that are furthest apart in the width direction, and the pair of support protrusions are provided on the inner surface of the peripheral wall portion that faces the inner surface of the peripheral wall portion in the width direction near the central portion in the length direction of the inner surface of the peripheral wall portion. In addition, one embodiment of the present invention is characterized in that the pair of support protrusions are composed of a plurality of support protrusions each having the same distance from the top wall portion and spaced apart circumferentially on the inner surface of the peripheral wall portion. In addition, one embodiment of the present invention is characterized in that the inner surface of the peripheral wall portion has a width W1 and a length L1 perpendicular to this width W1, the volatilizer has a width W2 that is smaller than the width W1 of the inner surface of the peripheral wall portion and a length L2 that is perpendicular to this width W2 and smaller than the length L1 of the inner surface of the peripheral wall portion, and a pair of width-direction regulating walls are provided inside the peripheral wall portion that can abut on both sides of the width direction of the volatilizer and position the volatilizer within a predetermined range in the width direction of the inner surface of the peripheral wall portion. In addition, one embodiment of the present invention is characterized in that the pair of width-direction regulating walls extend on the inner surface of the peripheral wall portion from a point closer to the top wall portion than the pair of support protrusions to a point closer to the opening than the pair of support protrusions. In addition, one embodiment of the present invention is characterized in that the inner surface of the peripheral wall portion has a width W1 and a length L1 perpendicular to this width W1, the volatilizer has a width W2 that is smaller than the width W1 of the inner surface of the peripheral wall portion and a length L2 that is perpendicular to this width W2 and smaller than the length L1 of the inner surface of the peripheral wall portion, and a pair of lengthwise regulating walls are provided inside the peripheral wall portion that can abut on both sides of the lengthwise direction of the volatilizer and position the volatilizer within a predetermined range in the lengthwise direction of the inner surface of the peripheral wall portion. In addition, one embodiment of the present invention is characterized in that the pair of lengthwise regulating walls protrude from the top wall portion and extend from the top wall portion to a position closer to the opening than the pair of support protrusions. [Effects of the Invention]

[0006] According to one embodiment of the present invention, the volatile substance is supported from below by a pair of support protrusions that protrude toward each other from a pair of locations on the inner peripheral surface of the peripheral wall portion that faces in the width direction of the volatile substance support cap, and when the pair of locations on the peripheral wall portion that faces in the length direction are compressed and deformed in a direction that faces each other, the pair of locations on the peripheral wall portion that faces in the width direction are displaced in a direction that faces each other, thereby releasing the support of the volatile substance by the pair of support protrusions. In other words, the volatile substance can be removed simply by pressing the pair of locations on the peripheral wall portion that face each other in the length direction of the volatile substance support cap in a direction that faces each other, which is advantageous in that the volatile substance can be easily removed without getting your hands dirty with chemicals when disposing of it after use. Furthermore, if the inner surface of the peripheral wall portion has a width W1 and a length L1 perpendicular to the width W1, and a pair of support protrusions are provided on the inner surface of the peripheral wall portion facing each other in the width direction near the center of the length direction of the inner surface of the peripheral wall portion, the peripheral wall portion can be easily compressed and deformed, which is advantageous for easily removing the volatilized material. Furthermore, if the inner surface of the peripheral wall has a width W1 and a length L1 that is perpendicular to the width W1 and is greater than the width W1, and a pair of support protrusions are provided on the inner surface of the peripheral wall that face each other in the width direction near the center of the length of the inner surface of the peripheral wall, the pair of points of the peripheral wall that face each other in the length direction will be spaced apart from the width W1, making it easier to compress and deform the peripheral wall, which is advantageous for easily removing the volatilized material. Furthermore, if the inner surface of the peripheral wall has a width W1 and a length L1 perpendicular to the width W1, and both side portions of the peripheral wall that face the inner surface of the peripheral wall in the width direction are convex in directions away from each other, with the central portion in the length direction being formed by curved surfaces that are furthest apart in the width direction, and a pair of support protrusions are provided on the inner surface of the peripheral wall that face the inner surface of the peripheral wall in the width direction near the central portion in the length direction of the inner surface of the peripheral wall, this is advantageous for smoothly displacing the pair of portions of the peripheral wall that face each other in the width direction in directions away from each other when the peripheral wall is compressively deformed. Furthermore, if the pair of support protrusions is composed of multiple support protrusions that are each the same distance from the top wall portion and are spaced apart circumferentially on the inner surface of the peripheral wall portion, this is advantageous in supporting the volatilizer in a more stable state. Furthermore, if a pair of width-direction limiting walls are provided inside the peripheral wall portion, capable of abutting both width-direction sides of the volatilizer and positioning the volatilizer within a predetermined range in the width direction of the inner peripheral surface of the peripheral wall portion, when viewed in plan on the pair of support protrusions, the width-direction center of the volatilizer is not biased in the width direction of the peripheral wall portion, and the width-direction center of the volatilizer is located near the width-direction center of the peripheral wall portion, which is advantageous for efficient volatilization by the volatilizer and for improving appearance. Furthermore, when inserting the volatilizer, the pair of width-direction limiting walls guide the volatilizer between the pair of support protrusions, which is advantageous for facilitating the insertion of the volatilizer. Furthermore, providing a pair of width-direction limiting walls is advantageous for maintaining the width-direction center of the volatilizer positioned near the width-direction center of the peripheral wall portion when moving the volatilizer after insertion, such as when placing it in a desired location. Furthermore, if the pair of width-direction regulating walls are configured to extend on the inner surface of the peripheral wall portion from a point closer to the top wall portion than the pair of support protrusions to a point closer to the opening than the pair of support protrusions, when inserting the volatile material, the pair of width-direction regulating walls can guide the volatile material from the start of insertion to the completion of insertion, which is advantageous in making the insertion of the volatile material even easier. Furthermore, if a pair of lengthwise limiting walls are provided inside the peripheral wall portion, which can abut against both longitudinal sides of the volatilizer and position the volatilizer within a predetermined range in the longitudinal direction of the inner peripheral surface of the peripheral wall portion, when viewed in plan on the pair of support protrusions, the longitudinal center of the volatilizer will not be biased in the longitudinal direction of the peripheral wall portion, and the longitudinal center of the volatilizer will be located near the longitudinal center of the peripheral wall portion, which is advantageous for efficient volatilization by the volatilizer and for improving appearance. Furthermore, the provision of a pair of lengthwise limiting walls is advantageous for maintaining the longitudinal center of the volatilizer located near the longitudinal center of the peripheral wall portion when moving the volatilizer after insertion, such as when placing it in a desired location. Furthermore, if a pair of lengthwise regulating walls are protruded from the top wall portion and extend from the top wall portion to a position closer to the opening than the pair of support protrusions, they can be provided at the desired position in the lengthwise direction of the peripheral wall portion, and this is advantageous in terms of reducing material and reducing costs compared to providing them on the peripheral wall portion.

DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the volatilization device 10 of this embodiment is composed of a chemical container 12 that contains a liquid chemical Y, and a volatilization body support cap 14 that is connected to the top of the chemical container 12. The volatilization device 10 absorbs the chemical Y contained in the chemical container 12 with a liquid-absorbent wick 26 (liquid-absorbent member) described later, and causes the chemical Y to be impregnated into a volatilization body 28 described later, thereby volatilizing the chemical Y. In this embodiment, an example is shown in which the chemical Y is a deodorizer, but the present invention is applicable to all chemicals Y that are liquid and volatile, such as air fresheners, insect repellents, insecticides, fungicides, disinfectants, and repellents.

[0009] First, the drug container 12 will be described with reference to FIGS. The drug container 12 is configured to have a cylindrical neck 16, an elliptical cylindrical body 20, a shoulder 18 connecting the neck 16 and the body 20, and a bottom 22 closing the lower end of the body 20. The body 20 is not limited to an elliptical cylindrical shape, but may be a cylindrical shape, a flattened cylindrical shape, a rectangular or polygonal cylindrical shape, or the like.

[0010] Drug container 12 is made of a transparent material that does not allow gas (air) and drug Y to pass through. Drug container 12 in this embodiment is made of, for example, polyethylene terephthalate (PET), but various conventionally known materials such as polypropylene, polyester, and polyvinyl chloride can also be used.

[0011] At the upper end of the mouth portion 16, a circular opening 16A for injecting the medicine Y into the medicine container 12 is provided. A male thread 16B is provided on the outer circumferential surface of the mouth portion 16, and a closing cap (not shown) can be screwed onto the male thread 16B. When the volatilization device 10 is shipped, a closing cap is attached to the mouth portion 16, which seals the inside of the drug container 12 and prevents the volatilization of the drug Y. The closing cap is removed when the volatilization device 10 is used.

[0012] An inner plug 24 is attached to the opening 16A of the mouth portion 16. The inside plug 24 has an annular upper wall portion 24A that covers the edge of the opening 16A of the neck portion 16 from above, a cylindrical tube portion 24B that hangs down from the underside of the upper wall portion 24A and extends along the inner circumferential surface of the neck portion 16, a tube portion 24C that inserts and holds the liquid absorbent wick 26 (liquid-absorbent member), and a cylindrical liquid receiving portion 24D with a bottom that is provided between the upper end edge of the tube portion 24C and the inner circumferential edge of the upper wall portion 24A. The liquid receiving portion 24D has at least one vent hole (not shown).

[0013] 2, the inside stopper 24 is attached to the medicine container 12 by fitting the tubular portion 24B into the opening 16A of the medicine container 12 with the liquid-absorbent wick 26 inserted and held in the tubular portion 24C. At this time, the tubular portion 24C of the inside stopper 24 holds the liquid-absorbent wick 26 in a position where the lower end of the liquid-absorbent wick 26 contacts the inner surface of the bottom 22 of the medicine container 12 and the upper end of the liquid-absorbent wick 26 protrudes above the upper wall portion 24A of the inside stopper 24, i.e., protrudes from the opening 16. In this state, the lower surface of the upper wall portion 24A of the inside plug 24 contacts the edge of the opening 16A of the mouth portion 16.

[0014] The absorbent wick 26 is for absorbing the medicine Y contained in the medicine container 12 and guiding it to the volatilizer 28 that comes into contact with the upper end of the absorbent wick 26 . The liquid absorbent wick 26 is formed in a rod shape from a material capable of absorbing the drug Y, for example, a mixture of one or more porous materials such as felt, synthetic fiber bundles, natural fiber bundles, and foamed synthetic resin.

[0015] The volatilizer 28 is supported horizontally from below by a pair of support projections 32 (support portions 30), and contacts the upper end of the liquid absorbent wick 26 to impregnate the chemical substance Y and volatilize it. The volatilizer 28 has a size and shape that overlaps all of the support protrusions 32 when viewed in plan, and is formed in the shape of a plate with a predetermined thickness (for example, a thickness of about 1 mm to 50 mm, preferably about 5 mm to 20 mm). In this embodiment, the volatilizer 28 is formed in the shape of an elliptical plate with both ends in the long axis direction cut out parallel to each other, as shown by the dotted lines in FIG. By increasing the surface area of ​​the volatilizer 28, the volatilizer 28 can absorb, impregnate, and carry the chemical Y absorbed by the absorbent wick 26, and then efficiently volatilize the chemical Y into the air from its surface.

[0016] In this embodiment, the volatilizer 28 has the shape of an oval plate with both ends of the long axis cut parallel to each other, but this is not limited to this and any shape such as rectangular, trapezoidal, or circular may be used as long as it can be inserted inside the volatilizer support cap 14. Furthermore, the volatilizer 28 does not have to be formed to a uniform thickness, and may have, for example, a flat bottom surface and a spherical top surface. The volatilizer 28 is formed from a material that can absorb the drug Y when it comes into contact with the drug Y, such as paper such as natural paper or synthetic paper, or a porous material such as felt, synthetic fiber bundles, natural fiber bundles, or foamed synthetic resin.

[0017] Next, the volatilizer support cap 14 will be described with reference to FIGS. The volatilizer support cap 14 can be attached and detached to the top of the drug container 12, and has a top wall portion 34 and a peripheral wall portion 36 hanging down from the periphery of the top wall portion 34, and has an opening 38 at the bottom of the peripheral wall portion 36. The top wall portion 34 and the peripheral wall portion 36 are provided with a plurality of volatilization holes 40 for volatilizing the chemical Y. As shown in FIG. 6, the inner peripheral surface of the peripheral wall portion 36 has a width W1 and a length L1 that is perpendicular to the width W1 and is greater than the width W1. In this embodiment, the direction along the width W1 of the peripheral wall portion 36 is referred to as the width W direction, the direction along the length L1 of the peripheral wall portion 36 is referred to as the length L direction, and the direction perpendicular to the width W direction and the length L direction is referred to as the height H direction.

[0018] The peripheral wall portion 36 is formed to be elastically deformable so that when a pair of portions of the peripheral wall portion 36 opposing in the length L direction are compressed and deformed in a direction toward each other, a pair of portions of the peripheral wall portion 36 opposing in the width W direction are displaced in a direction away from each other. Such peripheral wall portion 36 can be made of various conventionally known materials such as synthetic resin and metal, and in this embodiment, synthetic resin is used. In this embodiment, the top wall portion 34 and the peripheral wall portion 36 are formed integrally, and are therefore formed from the same material; however, when viewed in a plane, the top wall portion 34 and the peripheral wall portion 36 may have different shapes when viewed in a plane, such as making the top wall portion 34 rectangular and the peripheral wall portion 36 oval.

[0019] In this embodiment, the top wall portion 34 and the peripheral wall portion 36 are both formed in the same elliptical shape in plan view, as shown in FIG. Both side portions of the inner circumferential surface of the peripheral wall portion 36 that face each other in the width W direction are convex in a direction away from each other in a plan view, and the central portion in the length L direction is formed by curved surfaces 44 that are furthest apart in the width W direction. Therefore, when a pair of portions of the peripheral wall portion 36 that face each other in the length L direction are compressively deformed in a direction toward each other, the pair of portions of the peripheral wall portion 36 that face each other in the width W direction smoothly elastically deform in a direction away from each other. The peripheral wall portion 36 is not limited to an elliptical shape in plan view, but may be circular, square, rectangular, etc., as long as it has a shape such that when a pair of portions of the peripheral wall portion 36 opposing in the length L direction are compressed and deformed in a direction toward each other, the pair of portions of the peripheral wall portion 36 opposing in the width W direction are elastically deformed in a direction away from each other.

[0020] As shown in FIGS. 2, 3, and 6 to 9, a support portion 30 that supports the volatilizer 28 from below is provided on the inner peripheral surface of the peripheral wall portion 36 of the volatilizer support cap 14. The support portion 30 is composed of a pair of support projections 32 that project in directions approaching each other from a pair of locations on the inner peripheral surface of the peripheral wall portion 36 that face each other in the width W direction. The pair of support projections 32 are provided on the inner peripheral surface of the peripheral wall portion 36 facing each other in the width W direction of the inner peripheral surface of the peripheral wall portion 36 near the center in the length L direction of the inner peripheral surface of the peripheral wall portion 36. The pair of support projections 32 are each composed of a plurality of support projections 32 that are spaced apart in the circumferential direction on the inner circumferential surface of the peripheral wall portion 36 and are each the same distance from the top wall portion 34 .

[0021] In this embodiment, since the peripheral wall portion 36 is formed in an elliptical shape, a pair of support protrusions 32 are provided on the inner surface of the peripheral wall portion 36 facing each other in the width W direction, which is the minor axis direction of the ellipse. In this embodiment, two pairs of support protrusions 32 are provided on the inner surface of the peripheral wall portion 36 facing each other in the width W direction, i.e., four support protrusions 32, sandwiched between the center of the inner surface of the peripheral wall portion 36 in the length L direction. Furthermore, as shown in FIG. 3, the support protrusion 32 in this embodiment has a trapezoidal cross section with a right-angled interior angle, and is provided on the inner peripheral surface of the peripheral wall portion 36 so that one surface 32A of the two surfaces sandwiching the right-angled interior angle of the trapezoid is the horizontal upper surface.

[0022] As described above, the volatilizer 28 of this embodiment is formed in the shape of an elliptical plate with both ends in the longitudinal direction cut parallel to each other. As shown in Figure 6, the volatilizer 28 has a width W2 that is smaller than the width W1 of the inner peripheral surface of the peripheral wall portion 36, and a length L2 that is perpendicular to the width W2 and smaller than the length L1 of the inner peripheral surface of the peripheral wall portion 36. As a result, the volatilizer 28 can be supported substantially horizontally by two pairs of support protrusions 32, that is, four support protrusions 32. In this embodiment, two pairs of support protrusions 32, i.e., four support protrusions 32, are provided, but the configuration may also be such that one pair of support protrusions 32 (two support protrusions 32) or three pairs of support protrusions 32 (six or more support protrusions 32) are provided.

[0023] Furthermore, as shown in Figures 6 to 9, a pair of width-direction regulating walls 46 are provided inside the peripheral wall portion 36, which can abut against both widthwise sides of the volatilizer 28 and position the volatilizer 28 within a predetermined range in the width W direction of the inner peripheral surface of the peripheral wall portion 36. The pair of width-direction regulating walls 46 are arranged opposite each other in the width W direction of the inner surface of the peripheral wall portion 36, at locations near each of the pair of support protrusions 32 in the circumferential direction of the inner surface of the peripheral wall portion 36, with a distance greater than the width W2 of the volatilizer 28. The pair of width direction restricting walls 46 extend on the inner peripheral surface of the peripheral wall portion 36 from a position closer to the top wall portion 34 than the pair of support protrusions 32 to a position closer to the opening 38 than the pair of support protrusions 32.

[0024] 8 and 9, the width direction restricting walls 46 of this embodiment are formed in a rod shape with a rectangular cross section, and a pair of width direction restricting walls 46 are provided between the center in the length L direction of the inner peripheral surface of the peripheral wall portion 36 and the pair of support protrusions 32. In other words, four rod-shaped width direction restricting walls 46 are provided along the height H direction. The pair of width direction restricting walls 46 may be provided to protrude from the top wall portion 34, but providing them on the peripheral wall portion 36 is advantageous in terms of reducing the material used in the volatilizer support cap 14.

[0025] Furthermore, as shown in Figures 6 to 9, a pair of lengthwise regulating walls 48 are provided inside the peripheral wall portion 36, which can abut against both longitudinal sides of the volatilizer 28 and position the volatilizer 28 within a predetermined range in the length L direction of the inner surface of the peripheral wall portion 36. The pair of length direction restricting walls 48 are provided facing each other in the length L direction of the inner peripheral surface of the peripheral wall portion 36 at an interval that is greater than the length L2 of the volatilizer 28. The pair of length direction restricting walls 48 protrude from the top wall portion 34 and extend from the top wall portion 34 to a position closer to the opening 38 than the pair of support projections 32 .

[0026] As shown in Figures 2, 7, and 8, the length-direction regulating wall 48 in this embodiment is composed of a rectangular plate member 48A arranged along the width W direction and a right-angled triangular auxiliary plate member 48B arranged perpendicular to the plate member 48A on the outer surface of the plate member 48A. Auxiliary plate member 48B is provided to maintain plate member 48A perpendicular to top wall portion 34. In addition, two rod-shaped protrusions with rectangular cross section are formed at a distance from each other on the inner surface of plate member 48A to suppress movement of volatilizer 28 in the width direction. The pair of length direction restricting walls 48 may be provided to protrude from the peripheral wall portion 36, but providing them on the top wall portion 34 is advantageous in terms of reducing the material used in the volatilizer support cap 14.

[0027] As described above, in this embodiment, a pair of width-direction regulating walls 46 and a pair of length-direction regulating walls 48 are provided, so that the volatilizer 28 is supported by a pair of support protrusions 32 (holding portion 30) with its width-direction central portion approximately aligned with the width W-direction central portion of the top wall portion 34 and its length-direction central portion approximately aligned with the length L-direction central portion of the top wall portion 34.

[0028] When inserting and attaching the volatilizer 28 into the volatilizer support cap 14, hold the volatilizer support cap 14 with one hand so that the opening 38 faces upward, and hold the volatilizer 28 with the other hand, and align the orientation of the volatilizer 28 with respect to the volatilizer support cap 14 above the opening 38. In other words, align the orientation so that the curved portion 28A of the volatilizer 28 faces the curved surface 44 of the peripheral wall portion 36 on which the pair of support protrusions 32 are provided.

[0029] Next, the volatilizer 28, which is tilted so that its width is inclined, is inserted between a pair of longitudinal regulating walls 48 inside the volatilizer support cap 14, and one curved portion 28A of the volatilizer 28 is inserted between one support protrusion 32 and the top wall portion 34. When one curved portion 28A of the volatilizer 28 abuts against one of the width-direction regulating walls 46, the other curved portion 28A of the volatilizer 28 is pressed toward the top wall portion 34 and pushed between the other support protrusion 32 and the top wall portion 34.The volatilizer 28 is guided by the pair of width-direction regulating walls 46, and the volatilizer 28 can be inserted between the pair of support protrusions 32 and the top wall portion 34. Then, when the volatilizer support cap 14 is turned over so that the opening 38 faces downward, the volatilizer 28 is supported from below by the pair of support protrusions 32, as shown in Figure 11 (A).

[0030] As shown in Figure 10, the peripheral wall portion 36 is formed to be elastically deformable so that when a pair of portions of the peripheral wall portion 36 opposing in the length L direction are pressed toward each other and compressed, the pair of portions of the peripheral wall portion 36 opposing in the width W direction are displaced away from each other. The support of the volatilizer 28 by the pair of support protrusions 32 is released by compressing and deforming a pair of portions of the peripheral wall portion 36 that face each other in the length L direction in such a direction that they approach each other.

[0031] Specifically, as shown in FIG. 11(A), the volatilizer support cap 14 is placed in a state where the opening 38 faces downward. Then, as shown in FIG. 10, a pair of pressing points 36A facing each other in the length L direction of the peripheral wall portion 36 near the opening 38 are pressed toward each other as if sandwiching them between the thumb and any finger other than the thumb, i.e., pressed inward (direction P in the figure) to compress and deform the same.

[0032] As a result, a pair of displacement portions 36B opposed to each other in the width W direction of the peripheral wall portion 36 are displaced in directions away from each other, that is, outwardly, and elastically deformed. At this time, the pair of displacement portions 36B of the peripheral wall portion 36 near the opening 38 are displaced significantly, and accordingly, the pair of displacement portions 36B of the peripheral wall portion 36 on which the pair of support projections 32 are provided are also displaced outward. As a result, the distance between the pair of support protrusions 32 in the width W direction becomes larger than the width W2 of the volatilizer 28, and as shown in Figure 11 (B), the support of the volatilizer 28 by the pair of support protrusions 32 is released, the volatilizer 28 falls, and the volatilizer 28 can be removed from the volatilizer support cap 14.

[0033] Thus, according to this embodiment, the volatilizer 28 is supported from below by a pair of support protrusions 32 that protrude toward each other from a pair of locations on the inner surface of the peripheral wall portion 36 that face each other in the width W direction, and when the pair of locations on the peripheral wall portion 36 that face each other in the length L direction are compressed and deformed in a direction that brings them closer to each other, the pair of locations on the peripheral wall portion 36 that face each other in the width W direction are displaced in a direction that moves away from each other, thereby releasing the support of the volatilizer 28 by the pair of support protrusions 32. In other words, the volatilizer 28 can be removed simply by pressing a pair of opposing portions of the peripheral wall portion 36 in the length L direction toward each other, which is advantageous in that the volatilizer 28 can be easily removed without soiling the hands with the chemical Y when disposing of it after use.

[0034] Furthermore, the inner surface of the peripheral wall portion 36 has a width W1 and a length L1 perpendicular to the width W1, and a pair of support protrusions 32 are provided on the inner surface of the peripheral wall portion 36 facing the width W direction of the inner surface of the peripheral wall portion 36 near the center of the inner surface of the peripheral wall portion 36 in the length L direction, so that the peripheral wall portion 36 can be easily compressed and deformed, which is advantageous for easily removing the volatilization material 28.

[0035] Furthermore, the inner surface of the peripheral wall portion 36 has a width W1 and a length L1 that is perpendicular to the width W1 and is greater than the width W1, and a pair of support protrusions 32 are provided on the inner surface of the peripheral wall portion 36 facing the width W direction of the inner surface of the peripheral wall portion 36 near the center of the inner surface of the peripheral wall portion 36 in the length L direction.As a result, the pair of points of the peripheral wall portion 36 facing in the length L direction are spaced apart from the width W1, which makes it even easier to compress and deform the peripheral wall portion 36, which is advantageous for easily removing the volatilization material 28.

[0036] Furthermore, the inner surface of the peripheral wall portion 36 has a width W1 and a length L1 perpendicular to the width W1, and both side portions of the peripheral wall portion 36 that face the inner surface of the peripheral wall portion 36 in the width W direction are convex in directions away from each other, with the central portion in the length L direction being formed by curved surfaces 44 that are furthest apart in the width W direction, and a pair of support protrusions 32 are provided on the inner surface of the peripheral wall portion 36 that face the inner surface of the peripheral wall portion 36 in the width W direction near the central portion in the length L direction of the inner surface of the peripheral wall portion 36. This is advantageous when compressing and deforming the peripheral wall portion 36, as it allows the pair of portions of the peripheral wall portion 36 that face each other in the width W direction to be smoothly displaced away from each other.

[0037] In addition, since the pair of support protrusions 32 is composed of multiple support protrusions 32 that are each the same distance from the top wall portion 34 and are spaced apart circumferentially on the inner surface of the peripheral wall portion 36, this is advantageous in supporting the volatilizer 28 in a more stable state.

[0038] In addition, a pair of width-direction regulating walls 46 are provided inside the peripheral wall portion 36, which can abut against both widthwise sides of the volatilizer 28 and position the volatilizer 28 within a predetermined range in the width W direction of the inner surface of the peripheral wall portion 36.Therefore, when viewed in a plane on the pair of support protrusions 32, the widthwise center of the volatilizer 28 is not biased in the width W direction of the peripheral wall portion 36, and the widthwise center of the volatilizer 28 is located near the center in the width W direction of the peripheral wall portion 36, which is advantageous for efficient volatilization by the volatilizer 28 and for improving its appearance. Furthermore, when inserting the volatilizer 28, the pair of width-direction regulating walls 46 guide the volatilizer 28 between the pair of support protrusions 32, which is advantageous in facilitating the insertion of the volatilizer 28. In addition, by providing a pair of width-wise regulating walls 46, it is advantageous to maintain the width-wise center of the volatilizer 28 positioned near the center of the width W direction of the peripheral wall portion 36 when moving the volatilizer 28 after insertion, such as when placing it in a desired location.

[0039] Furthermore, since the pair of width-direction regulating walls 46 extend on the inner surface of the peripheral wall portion 36 from a location closer to the top wall portion 34 than the pair of support protrusions 32 to a location closer to the opening 38 than the pair of support protrusions 32, when inserting the volatilizer 28, the pair of width-direction regulating walls 46 can guide the volatilizer 28 from the start of insertion to the completion of insertion, which is advantageous in making the insertion of the volatilizer 28 even easier.

[0040] In addition, a pair of lengthwise regulating walls 48 are provided inside the peripheral wall portion 36, which can abut against both longitudinal sides of the volatilizer 28 and position the volatilizer 28 within a predetermined range in the length L direction of the inner surface of the peripheral wall portion 36.Therefore, when viewed in a plane on the pair of support protrusions 32, the longitudinal center of the volatilizer 28 is not biased in the length L direction of the peripheral wall portion 36, and the longitudinal center of the volatilizer 28 is located near the longitudinal center of the peripheral wall portion 36, which is advantageous for efficient volatilization by the volatilizer 28 and for improving its appearance. In addition, by providing a pair of lengthwise regulating walls 48, it is advantageous to maintain the lengthwise center of the volatilizer 28 positioned near the center of the length L of the peripheral wall portion 36 when moving the volatilizer 28 after insertion, such as when placing it in a desired location.

[0041] Furthermore, a pair of lengthwise regulating walls 48 protrude from the top wall portion 34 and extend from the top wall portion 34 to a position closer to the opening 38 than the pair of support protrusions 32, so that they can be provided at a desired position in the length L direction of the peripheral wall portion 36, and this is advantageous in terms of reducing material and reducing costs compared to providing them on the peripheral wall portion 36.
