Description

[Technical field]

[0001] The present invention relates to a vaporization container. [Background technology]

[0002] One type of volatilization container known in the art has a core material holding frame consisting of a pair of opposing clamping plates that is suspended from the back side of a cap that is fitted onto the mouth and neck of the container body, and a vertically elongated volatilization portion, which is one half of a strip-shaped core material, is clamped between the clamping plates, while the other half of the core material, which is the suction portion, is stored in a superimposed manner within the bottom of the container body (Patent Document 1). A pair of protrusions are provided inside the mouth and neck portion which are pressed against the outside of the pair of clamping plates, and the frictional force between the clamping plates and the protrusions can hold the raised core holding frame at the required height. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2013-13483 Summary of the Invention [Problem to be solved by the invention]

[0004] The volatilization container of Patent Document 1 can adjust the amount of volatilization by increasing or decreasing the exposed area of ​​the volatilization section depending on the height to which the core material holder is pulled out. However, when, for example, an aromatic agent is stored, even if the core holder is pulled out higher, it takes a certain amount of time before the user can actually sense that the fragrance has become stronger. If you want to temporarily increase the amount of vapor emitted, you need to close the cap and shake the container, but this is a cumbersome procedure.

[0005] A first object of the present invention is to provide a volatilization container that allows the amount of volatilization to be easily adjusted. A second object of the present invention is to enable the amount of volatilization to be increased relatively quickly in the container. [Means for solving the problem]

[0006] The first means includes a container body 2 having a mouth and neck portion 6 standing upright, A cap 20 is attached to the upper side of the container body 2, and is formed by connecting a top wall 30 that covers the upper part of the mouth and neck part 6 to the upper end of an outer peripheral wall 22, and has a main volatilization port A1 opened on the outer peripheral wall 22 and a secondary volatilization port A2 opened on the top wall 30; A volatilizer 18 is incorporated in the cap 20 and disposed on the neck portion 6; An impregnated rod 16 suspended from the inside of the neck portion 6 in contact with the volatilizer 18; An elastic dome-shaped top plate 52 is placed on the top wall 30 to cover the secondary evaporation port A2, and a linking means J is provided to link the zenith portion 54 of the top plate 52 to the top wall 30 so that the zenith portion 54 can be raised and lowered, and an auxiliary cover 50 is provided so that the top plate 52 is inverted from a dome shape to an inverted dome shape when the zenith portion 54 is lowered.

[0007] In this means, as shown in FIG. 1, a main evaporation port A1 is opened in the outer peripheral wall 22 of the cap 20, and a secondary evaporation port A2 is opened in the top wall 30 thereof, and an elastic dome-shaped top plate 52 is disposed on the top wall 30 so as to cover the secondary evaporation port A2. A linking means J is provided to link the zenith portion 54 of the tabletop 52 to the top wall 30 so that the zenith portion 54 can be raised and lowered, and as shown in Figure 3(B), the tabletop 52 is formed so that the dome shape is inverted into an inverted dome shape when the zenith portion 54 is lowered. According to this structure, by simply raising and lowering the zenith portion 54, it is possible to switch between a first mode in which evaporation occurs only from the main evaporation port A1 shown in Figure 3(A) and a second mode in which evaporation occurs from the main evaporation port A1 and the secondary evaporation port A2 shown in Figure 3(B), thereby making it possible to easily adjust the amount of evaporation. Furthermore, when switching from the first mode to the second mode, the volatile components already accumulated inside the dome-shaped top plate 52 are released from the secondary volatilization port, so that the amount of volatilization can be increased relatively quickly.

[0008] The second means includes the first means and is provided with a positioning means P for temporarily fixing the zenith portion 54 at a lower limit position; A receiving portion 42 is formed on the upper side of the top wall 30 to receive the lower surface of the top plate 52 in the inverted state into the inverted dome shape. The top plate 52 is provided so that the top portion 54 is temporarily fixed at the lowest position with the lower surface of the top plate 52 supported by the receiving portion 42.

[0009] In this embodiment, as shown in FIG. 3B, a positioning means P is provided for temporarily fixing the top portion 54 at the lowest position. As shown in Figure 2, a receiving portion 42 is formed on the upper side of the top wall 30 to support the underside of the tabletop 52 in the inverted inverted dome shape, and the zenith portion 54 is temporarily fixed in the lowest position when the underside of the tabletop 52 is supported by the receiving portion 42. This structure ensures that the inverted dome-shaped top plate 52 can be reliably maintained in an inverted state (high-speed volatilization state) and reduces the risk of the top plate 52 suddenly returning to its dome shape if, for example, another object hits it, making it easy to use.

[0010] The third means has the first means or the second means, and is provided with a positioning means P for temporarily fixing the zenith portion 54 at a lower limit position; The linking means J is formed by inserting a linking rod 62 suspended from the zenith portion 54 into an insertion hole 44 formed in the top wall 30 so as to be movable up and down. As the positioning means P, a locking projection 64 having a size large enough to overcome the peripheral edge 46 around the insertion hole 44 is provided on the outer circumferential surface of the linking rod 62 near the top portion 54, A straight rod portion 63 formed as a portion of the link rod 62 below the locking projection 64 moves up and down within the insertion hole 44, thereby fanning the top plate 52 in the up and down direction. In addition, the peripheral portion 46 of the insertion hole 44 is positioned between the locking projection 64 and the zenith portion 54, so that the zenith portion 54 is temporarily fixed at the lowest position.

[0011] In this means, as shown in Figure 2, the linking means J is a linking rod 62 that is suspended from the zenith portion 54 and is inserted into an insertion hole 44 drilled in the top wall 30 so that the linking rod 62 can be raised and lowered. In addition, as a positioning means P for temporarily fixing the zenith portion 54 at the lower limit position shown in Figure 3 (B), a locking protrusion 64 is provided on the outer surface of the connecting rod 62, positioned near the zenith portion 54, and large enough to overcome the peripheral portion 46 around the insertion hole 44. As shown in Figure 3(C), the straight rod portion 63 of the connecting rod 62 formed as the portion below the locking protrusion 64 is moved up and down within the insertion hole 44, thereby fanning the top plate 52 in the vertical direction, and the peripheral portion 46 of the insertion hole 44 is positioned between the locking protrusion 64 and the zenith portion 54, thereby temporarily fixing the zenith portion 54 in the lowest position. According to this structure, the volatilization speed can be increased by the agitation of the top plate 52.

[0012] The fourth means includes any one of the first means to the third means, and the top wall 30 includes a pressing means D for relatively pushing up the top plate 52 around the zenith portion 54 as the zenith portion 54 descends.

[0013] In this embodiment, the top wall 30 has a pressing means D for relatively pushing up the top plate 52 around the zenith portion when the zenith portion 54 is pressed down as shown in FIG. 3(B). According to this structure, by pressing down the zenith portion 54, it is possible to reliably realize the operation of inverting the top plate 52 from a dome shape to an inverted dome shape. The description in this paragraph is incorporated by reference into the fifth means.

[0014] The fifth measure is 2 The method includes: The top wall 30 has a pressing means D for relatively pushing up the top plate 52 around the zenith portion 54 as the zenith portion 54 descends, The central portion of the top wall 30 is formed into a raised portion 34 that is raised into a cylindrical shape with a top, and the raised portion is connected to the zenith portion 54 via the connecting means J. The peripheral end 58 of the top plate 52 is in contact with the peripheral portion 32 of the top wall 30 located outside the raised portion 34, The upper surface of the raised portion 34 is formed as a concave curved surface as the receiving portion 42, The linking means J is provided on a part of the concave curved surface 42, The ridge portion 38 formed on the periphery of the concave curved surface 42 serves as the pressing means D and is abutted against the lower surface of the top plate 52 around the apex portion 54 .

[0015] In this embodiment, the top wall 30 has a pressing means D for relatively pushing up the top plate 52 around the zenith portion when the zenith portion 54 is pressed down as shown in FIG. 3(B). Also In this embodiment, as shown in FIG. 2, the central portion of the top wall 30 is formed into a raised portion 34 that is raised in a cylindrical shape with a top, and the raised portion 34 is connected to the zenith portion 54 . Further, the tip portion 58 of the top plate 52 abuts against the peripheral portion 32 of the top wall 30 located outside the raised portion 34 . The upper surface of the raised portion 34 is formed into a concave curved surface as the receiving portion 42, and the linking means J is provided on a part of this concave curved surface 42. Further, the ridge portion 38 formed on the periphery of the concave curved surface 42 serves as the pressing means D and is in contact with the lower surface of the top plate 52 around the periphery of the top plate 52 . With this structure, as shown in Figures 3(A) and 3(B), by pushing down on the zenith portion 54 with the ridge portion 38 as a fulcrum, it is possible to easily invert the top plate 52 from a dome shape to an inverted dome shape, and by pushing down on the tip portion 58 of the top plate 52, it is possible to restore the top plate 52 to its original shape. Effect of the Invention

[0016] According to the present invention, the amount of volatilization can be easily adjusted and the amount of volatilization can be increased relatively quickly. [Brief description of the drawings]

[0017] [Figure 1] FIG. 2 is a cross-sectional view of a volatilization container according to an embodiment of the present invention. [Diagram 2] FIG. 2 is a cross-sectional view of a main part of the container of FIG. [Diagram 3]FIG. 2 is an explanatory diagram of the mode of operation of the container in FIG. 1, in which (A) shows a mode in which the secondary evaporation port is blocked with a dome-shaped top plate and evaporation occurs only from the main evaporation port (first mode), (B) shows a mode in which the top plate is inverted into an inverted dome shape and evaporation occurs from both the main evaporation port and the secondary evaporation port (second mode), and (C) shows a mode in which the volatile components are diffused by fanning the top plate (third mode). BEST MODE FOR CARRYING OUT THEINVENTION

[0018] 1 to 3 show an evaporation container according to an embodiment of the present invention. This volatilization container is composed of a container body 2, an inner plug 10, an impregnated rod 16, an volatilization body 18, a cap 20, and an auxiliary cover 50. Here, the container body 2, the inner plug 10, the cap 20, and the auxiliary cover 50 may be formed of, for example, a synthetic resin.

[0019] The container body 2 has a body portion 4 and a neck portion 6 standing upright via a shoulder portion 5 . The mouth / neck portion 6 is formed with a male thread portion 7 for screwing in a lid body (not shown), and a flange-shaped annular rib 9 is provided around the periphery of the male thread portion 7 below the male thread portion 7. The body 4 in the illustrated example is substantially cylindrical, and the upper part of the cylindrical wall is formed to have a small diameter that narrows via an upward step 4a. The lid body (not shown) is a disposable cap that is removed from the container body 2 when the volatilization container is used.

[0020] The inner plug 10 is a member for hanging the impregnated rod 16 from the mouth and neck portion 6, and a retaining tube 15 for holding the impregnated rod 16 hangs down from the upper end side of a fitting tubular portion 12 fitted into the mouth and neck portion 6, via a tapered wall portion 13 with a small diameter at its lower end. In the illustrated example, an air hole 14 is formed penetrating the tapered wall portion 13 in the vertical direction.

[0021] The impregnated rod 16 and the volatilizer 18 are formed from a material suitable for permeating the content liquid (for example, nonwoven fabric, synthetic fiber bundles, natural fiber bundles, foamed synthetic resin, etc.). The impregnated rod 16 is inserted through the retaining cylinder 15 and extends toward the bottom side of the container body 2. The upper end of the impregnated rod 16 protrudes upward from the upper surface of the inner plug 10. The volatilizer 18 is disposed above the neck portion 6 inside the cap 20 in contact with the upper end of the impregnated rod 16 .

[0022] A cap 20 is attached to the upper side of the container body 2 . The cap 20 has an outer peripheral wall 22 fitted to the upper part of the body 4, and a top wall 30 connected to the upper end of the outer peripheral wall 22 and covering the upper part of the mouth and neck part 6. A main evaporation hole A1 is opened in the outer peripheral wall 22, and a sub-evaporation hole A2 is opened in the top wall 30, both of which serve as evaporation ports. In this specification, the term "volatilization port" is a broader concept than "volatilization hole" and includes shapes other than holes that serve as an outlet for releasing volatile components (for example, the gap between the cap body 20a and the top cover 20b described below). In the illustrated example, the cap 20 is formed of a cap body 20a including a lower peripheral wall portion 22a, which is the lower half of the outer peripheral wall 22, and an upper lid 20b, which is removably placed on the cap body 20a and includes an upper peripheral wall portion 22b, which is the upper half of the outer peripheral wall 22, and the top wall 30. However, this structure can be modified as appropriate, and the entire cap 20 may be formed as a single unit. In the illustrated example, the lower end of the outer peripheral wall 22 is placed on the upward step 4a, and the outer surface of the body portion below the upward step 4a and the outer surface of the outer peripheral wall 22 are formed flush with each other. The cap body 20a has an inner peripheral wall 24 supported by a plurality of support arms 23A protruding inward from the lower peripheral wall portion 22a. The inner peripheral wall 24 surrounds the mouth / neck portion 6. The outer peripheral end of the annular rib 9 is in contact with the inner surface of the inner peripheral wall 24.

[0023] In this embodiment, a holding mechanism H is provided between the cap body 20a and the top lid 20b, which supports the top lid 20b in a state where it is lifted up from the upper surface of the cap body 20a. 1, the holding mechanism H is configured by connecting a vertical guide rail 26 with a channel groove 27 to the lower peripheral wall portion 22a via a support piece 23B, and inserting a leg plate 33 suspended from the top wall 30 into the channel groove 27 so that the leg plate 33 can be raised and lowered. A plurality of horizontal rib-like engaging ribs (not shown) are arranged at equal intervals in the vertical direction on the leg plate 33, and recessed receiving portions (not shown) into which the engaging ribs are detachably fitted are formed in the channel groove, so that the height of the upper cover 20b can be adjusted by the engaging ribs and the recessed receiving portions. However, these structures can be modified as appropriate, and the holding mechanism may be omitted. The reason for providing the holding mechanism H is that by lifting the top lid 20b from the cap body 20a, the gap (not shown) between the cap body 20a and the top lid 20b can be used as an evaporation port to release volatile components. The gap is not shown because it is well known, but the upper lid 20b may be pulled up from the state shown in FIG. 3(B) so that the volatile components can be released from the gap with the cap body 20a. In addition, a structure in which the gap is used as the main evaporation port instead of the main evaporation hole having a hole shape is also included in the technical scope of the present invention.

[0024] The top wall 30 has a central portion which is raised into a cylindrical shape with a top, forming a raised portion 34, and a peripheral portion 32 which is a horizontal wall portion having a flat upper surface. The "periphery" means a ring-shaped portion located around the raised portion (horizontally outward), and is not limited to a portion near the peripheral edge of the top wall. As shown in FIG. 2, the raised portion 34 is formed by connecting an upper wall portion 40 to the upper end of the cylindrical wall portion 36, which closes the upper surface of the cylindrical wall portion, and opening an insertion hole 44 in the center of the upper wall portion 40 for inserting a connecting rod 62, which will be described later. However, the position of this insertion hole 44 can be changed as appropriate, and it may be positioned at a position offset from the center of the upper wall portion 40 (eccentric position) as long as it does not interfere with the operation of the top plate 52 described below (such as the raising and lowering of the zenith portion 54). The number of communication holes 44 and later-described connection rods 62 can be changed as appropriate. For example, a pair of communication holes may be provided, and two connection rods hanging down from the apex portion 54 of the top plate 52 may be inserted into each of the communication holes. In this structure, the pair of insertion holes 44 may be disposed in symmetrical positions (180° symmetrical positions) shifted from the center of the upper wall portion 40. In the present embodiment, as shown in the drawing, the upper surface of the upper wall portion 40 is a concave curved surface 42 that is concave downward. The concave curved surface 42 is formed in the shape of a partial spherical surface (a surface obtained by cutting out a part of a spherical surface). The concave curved surface 42 serves as a support for supporting the underside of a tabletop 52, which will be described later, that is inverted into an inverted dome shape as shown in Fig. 3(B). Note that in this specification, "support" means to receive and support from below. In order to stably support the inverted dome-shaped top plate 52 , the receiving portion 42 may be structured to support the lower end of the inverted dome-shaped top plate 52 so as to surround the periphery of the connecting rod 62 . Although not shown in the figure, instead of forming the upper surface of the upper wall portion 40 into a concave curved surface, a structure may be used in which multiple supporting pieces standing up at the same height from the horizontal upper surface (the height at which their upper ends reach the imaginary horizontal plane E described below) are arranged, when viewed from above, on an imaginary circle centered on the insertion hole shown in the figure.

[0025] Between the concave curved surface 42 and the outer circumferential surface 37 of the cylindrical wall portion 36, a ridge portion 38 having an annular shape when viewed from above is formed. As shown in FIG. 2, the ridge portion 38 is formed so as to lie on an imaginary horizontal plane E that is parallel to the peripheral portion 32 of the top wall 30 . The ridge portion 38 is an abutment portion that abuts against the underside of a dome-shaped top plate 52 described below, and plays a role as a pressing means D that passively applies a push-up force f (a reaction to a push-down force F) to the abutment point of the top plate 52 when the apex portion 54 of the top plate 52 is pushed down (see FIG. 3(A)). This role will be described later. In addition, instead of a structure in which the top plate 52 is inverted by the upward pushing force from the ridge portion 38, the thickness and material of the inverting portion (the portion other than the top plate portion 54) may be designed so that the top plate 52 can be inverted with a small force, and the top plate 52 may be formed so that it can be inverted into an inverted dome shape by only the force of pushing the zenith portion 54 downward.

[0026] In this embodiment, an appropriate number (two in the illustrated example) of secondary volatilization holes A2 are opened in the cylindrical wall portion 36 of the raised portion 34. However, the arrangement of the secondary volatilization holes A2 can be changed as appropriate, and may be located within the area of ​​the top wall 30 that is covered by the auxiliary cover 50. In the illustrated example, the secondary volatilization holes A2 may be located, for example, on the inner periphery of the peripheral portion 32, where the leg plate 33 is not provided. In the illustrated example, the cylindrical wall portion 36 is tapered with a smaller diameter at the upper end, but the shape can be changed as appropriate.

[0027] The auxiliary cover 50 has the role of stopping or promoting the release of volatile components from the secondary volatilization hole A2. As shown in FIG. 2, the auxiliary cover 50 is formed of a top plate 52 and a connecting rod 62 .

[0028] The top plate 52 is an elastic dome-shaped portion, and is disposed on the top wall 30 so as to cover the secondary vaporization hole A2. In this specification, the term "dome-shaped" refers to a shape that can expand downward from the zenith portion 54 to cover the upper surface of the top wall 30, and may be any shape that can block communication between the secondary vaporization port A2 and the outside of the top plate 52. The concept of "dome-shaped" includes, for example, a bowl shape, a hat shape, a tapered cylinder shape, a cone shape or a truncated cone shape, a pyramid shape or a truncated pyramid shape, and the like. Moreover, the term "inverted dome shape" refers to a shape that is vertically symmetrical to the "dome shape." In this embodiment, the top plate 52 is disposed to cover the raised portion 34 . The peripheral end 58 of the top plate 52 is placed on the upper surface of the peripheral portion 32 of the top wall 30 in a tight, non-permeable state without any gaps, so that the volatile components cannot pass through. For example, the dimensions of the top plate 52 may be designed so that the tip portion 58 of the top plate 52 is elastically pressed against the peripheral portion 32 in the state shown in FIG. The zenith portion 54 of the top plate 52 is connected to the top wall 30 via a connecting rod 62 connected to the zenith portion 54 so as to be movable up and down. The "zenith portion" refers to the highest part of the top plate 52 in the dome shape, and also serves as a push button when pressed down. Moreover, the top plate 52 abuts against the ridge portion 38 at a location (middle portion 60) between the vertex portion 54 and the tip portion 58. The top plate 52 has elasticity to the extent that it can elastically invert from the dome shape shown in FIG. 3(A) to the inverted dome shape shown in FIG. 3(B) and return to its original shape from the inverted dome shape to the dome shape. In the illustrated example, the dome shape and the inverted dome shape are depicted vertically symmetrically. However, the shape of the top plate 52 can be appropriately changed. The shape of the lower surface of the top plate 52 when inverted into an inverted dome shape matches the concave curved surface 42 of the raised portion 34 as shown in FIG. 3(B).

[0029] In this embodiment, the connecting rod 62 is suspended from the zenith portion 54 and inserted into the insertion hole 44 . In a preferred embodiment, as shown in FIG. 2, the lower end of the connecting rod 62 is provided with a stopper projection 66 that can be engaged with the lower surface of the upper wall portion 40 . The retaining projection 66 has a horizontal surface 66b formed on the upper side thereof, which serves as a retaining surface. In the preferred embodiment shown in the drawings, the annular horizontal surface portion 66b is provided so as to be in close contact with the lower surface of the peripheral portion 46 of the insertion hole 44 in the state shown in FIG. The retaining projection 66 is formed in a size that enables it to climb over the peripheral edge 46 around the insertion hole 44 when the linking rod 62 is inserted into the insertion hole 44 . An inclined surface 66a is formed on the lower side of the retaining projection 66 to facilitate the peripheral edge 46 getting over.

[0030] The structure of this embodiment, in which the connecting rod 62 is inserted into the insertion hole 44, is an example of the connecting means J described in the claims, i.e., a means for connecting the zenith portion 54 to the top wall 30 so that the zenith portion 54 can be raised and lowered, and may be modified as appropriate as long as the function of this connecting means is realized. For example, instead of the connecting rod, a hollow connecting tube may be suspended from the top portion 54 . Also, instead of the insertion hole 44, a fitting cylinder extending vertically from the top wall 30 may be recessed, and the link rod may be inserted into this fitting cylinder. In this specification, the term "linked" refers to a connection that leaves room for relative movement (up and down movement).

[0031] In this embodiment, the link rod 62 is provided with a positioning means P for temporarily fixing the zenith portion 54 at the lowest position. Specifically, a locking protrusion 64 is provided on the outer peripheral surface of the connecting rod 62, positioned near the zenith portion 54, and as shown in Figure 3 (B), a recess n is formed in the connecting rod portion between this locking protrusion 64 and the zenith portion 54, into which the peripheral portion 46 of the insertion hole 44 engages. In the illustrated example, the locking projection 64 is formed as an annular locking rib, but the structure can be modified as appropriate. The locking projection 64 , like the retaining projection 66 , is formed in a size that allows it to climb over the peripheral edge 46 around the insertion hole 44 . In this specification, the term "temporarily fixed" means that the zenith portion is stopped at the lowest position, and does not mean that the zenith portion itself is fixed to the raised portion.

[0032] In this embodiment, the connecting rod portion (straight rod portion 63 ) between the locking projection 64 and the retaining projection 66 is provided with a length and shape that allows it to move up and down within the insertion hole 44 . In the preferred illustrated example, the length L1 of the straight rod portion 63 is made approximately equal to the height difference L2 between the upper surface of the zenith portion 54 and the ridge portion 38. In this configuration, as long as the straight rod portion 63 formed between the locking projection 64 and the retaining projection 66 moves up and down within the insertion hole 44, the top plate 52 will not exceed the imaginary horizontal plane E and will not suddenly invert into an inverted dome shape.

[0033] In the above configuration, the mode of use of the volatilization container of the present invention is explained. First, the first mode of use will be described. In the state shown in Figure 1, the secondary volatilization hole A2 is covered by the auxiliary cover 50, so that the volatile components released from the volatilizer 18 that enter the inside of the dome-shaped top plate 52 remain inside the top plate 52 without being released to the outside. Therefore, the volatile components released from the volatilization container mainly pass through the main volatilization hole A1, as shown in FIG. 3(A). Therefore, the release of volatile components occurs at a relatively slow rate.

[0034] Next, the second mode of use will be described. When the zenith portion 54 is pressed down hard with a finger (to the lowest position), a downward force F is applied to the zenith portion 54, as shown by the white arrow in Figure 3 (A), and as a result, an upward force f, shown by the thick black arrow, acts as a reaction force from the ridge portion 38 to the intermediate portion 60. Then, due to a seesaw effect with the ridge portion 38 as a fulcrum, as shown in FIG. 3B, the top portion 54 of the tabletop 52 descends and the tip portion 58 ascends. As a result, the top plate 52 is inverted from a dome shape to an inverted dome shape. In this inverted state, the volatile components released from the volatilizer 18 pass through the main volatilization hole A1 and the sub volatilization hole A2. Therefore, the rate at which volatile components are released is relatively rapid. In particular, immediately after the top plate 52 is inverted from the dome shape to the inverted dome shape, the volatile components remaining within the top plate 52 flow out to the outside, temporarily increasing the amount of emission. In addition, the underside of the inverted dome-shaped top plate 52 is in close contact with the concave curved surface 42, and in this state the zenith portion 54 is temporarily fixed at the lowest position by the positioning means P, so that the inverted state of the top plate 52 is stably maintained. When it is desired to return the top plate 52 to its dome shape, the tip 58 of the top plate 52 may be pressed down at multiple suitable points (for example, on both diametrical sides of the top plate 52) with fingers or the like from the state shown in FIG. 3(B).

[0035] A third mode of use will now be described. 3(A), when the zenith portion 54 is slightly pressed down within a range not exceeding the above-mentioned imaginary horizontal plane E, the outer periphery of the tabletop 52 can be fanned. In this specification, "fanning" refers to swinging like a fan. Therefore, by repeatedly moving the zenith portion 54 up and down in small increments, the agitating action can be continued, mixing the volatile components together with the air and facilitating their release to the outside.

[0036] According to the above configuration and action, a main evaporation hole A1 is opened in the outer wall 22 of the cap 20, and a secondary evaporation hole A2 is opened in the top wall 30 thereof. An elastic dome-shaped top plate 52 is arranged on the top wall 30 so as to cover the secondary evaporation hole A2. A linking means J is provided to link the zenith portion 54 of the top plate 52 to the top wall 30 so that the zenith portion 54 can be raised and lowered. The top plate 52 is formed so that it is inverted from a dome shape to an inverted dome shape when the zenith portion 54 is lowered. Therefore, the amount of evaporation can be easily adjusted by the simple operation of raising and lowering the zenith portion 54, and in particular the amount of evaporation can be increased relatively quickly. Furthermore, a positioning means P is provided for temporarily fixing the zenith portion 54 at the lowest position, and the zenith portion 54 is temporarily fixed in a state in which the lower surface of the tabletop 52 is supported by the receiving portion 42 formed on the upper side of the top wall 30. This makes it easy to use as the inverted state of the tabletop 52 can be reliably maintained. In addition, the linking means J comprises a linking rod 62 suspended from the zenith portion 54, which is inserted into the insertion hole 44 provided in the top wall 30 so that it can be raised and lowered. As the linking rod 62 is raised and lowered, the top plate 52 is agitated in the vertical direction, thereby further increasing the volatilization rate. Furthermore, since the pressing means D is provided for relatively pushing up the top plate 52 as the zenith portion 54 descends, the top plate 52 can be reliably inverted from a dome shape to an inverted dome shape. Furthermore, the central portion of the top wall 30 is formed into a raised portion 34 that is raised into a cylindrical shape with a top, and a ridge portion 38 formed on the periphery of the concave curved surface 42 that is the upper surface of this raised portion 34 is abutted against the underside of the tabletop 52 as the pressing means D. Therefore, with the ridge portion 38 as a fulcrum, it is easy to invert the tabletop 52 from a dome shape to an inverted dome shape and restore it to its original shape. [Explanation of symbols]
