Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a volatilization container for volatile solutions such as fragrance, deodorizing liquid, insecticidal liquid, etc.

The volatilization container according to the present invention can be used in all fields. For example, if a perfume liquid containing perfume or the like is used as the solution contained in the container, the container can be used as a deodorizing fragrance container. In addition, if insecticidal liquid, insect repellent liquid, sterilizing liquid, anti-mold liquid, or a mixture thereof is used instead of perfume liquid, the insecticide volatilization container,
It can be used as a disinfectant volatilization container, etc., and can be used for various purposes depending on the type of liquid used.

Prior Art Conventionally known aroma volatilization containers include a type in which a core material is directly immersed in a container containing an aroma liquid and the aroma liquid is volatilized from the end of the core material exposed from the container, or a type in which the aroma liquid is volatilized from the end of the core material exposed from the container. There is a type that evaporates aromatic liquid from the incense storage piece that comes into contact with the part (Utility Model Application Publication No. 55-10700, Publication No. 55-104435,
Publication No. 55-10699, Publication No. 55-122736, Publication No. 54
(See Publication No.-119846, Publication No. 53-120246, etc.)
However, in this type of aroma volatilization container, since the core material is directly immersed in the aroma liquid, the fragrance that volatilizes easily is volatilized first, and the aroma odor becomes extremely weak after 1 to 2 weeks, and it will last for a long time. There was a problem that it was not possible to emit a constant aroma for a certain period of time.

Purpose of the invention In view of the above circumstances, the present inventors have solved the above problem by replenishing the solution to the impregnated piece using the siphon principle, and have always been able to continuously and continuously supply perfume liquid with a constant composition. We have devised a volatilization container that can effectively supply the solution and have filed a separate application for it, but the present invention also allows for the replenishment and volatilization of solution automatically and reliably by simply attaching an impregnated piece to the container. The purpose of the present invention is to provide a volatilization container that is provided with a liquid return mechanism and completely eliminates the fear of solution overflowing to the outside of the system, especially in the final stage of volatilization.

Configuration of the invention The volatilization container according to the invention includes a cylindrical body that can form a negative pressure space protruding from the upper part of the impregnated piece support base, a packing support cylinder protruding from the lower part of the cylindrical body, and
an impregnated piece support base in which an impregnated piece of water-absorbing material is placed around the cylindrical body, and one end formed in a U-shape or a line; and a supply pipe inserted into the impregnated piece support base through a packing support cylinder so that the other end is immersed in the solution in the container, so as to be disposed inside the cylindrical body. In this step, a packing having an outer circumferential ring with a notch or small hole for ventilation is fixed to the lower end of the packing support tube of the impregnated piece support, and thereby the impregnated piece support on which the impregnated piece is mounted is attached to the container. The liquid can be automatically replenished and volatilized by simply putting it on, and one or more liquid return holes are provided at the impregnation piece support located at the top of the packing. ,
It is characterized by preventing the solution from overflowing to the outside of the system.

Embodiments Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

FIG. 1 shows an embodiment of the volatilization container of the present invention,
In the figure, 1 is a container containing a solution 2 such as an aromatic liquid or an insecticidal liquid, and a neck part 3 and a protruding opening part 4 are provided at the top of the container.
is provided. A plurality of protrusions 5 are provided on the outer periphery of the neck portion 3 to protrude in the longitudinal direction, while an air hole 6 is bored at the upper end of the ejection port 4 (a notch is provided at the upper end of the ejection port). ), both of which communicate the internal space of the container 1 with the outside air.

Reference numeral 7 designates a dish-shaped impregnated piece support stand, and at the center of the upper surface of the impregnated piece support stand 7 is a cylindrical body 9 of a predetermined length made of an elastic material such as a soft synthetic resin so as to form a sealed space. is arranged, and a liquid passage hole 1 is provided in the lower part of the cylindrical body 9 near the joint with the impregnated piece support 7.
0 is provided. On the other hand, a cylindrical packing support tube 11 of a predetermined length is protruded from the center of the lower surface of the impregnated piece support base 7, and the tip of the packing support tube 11 has a groove formed of rubber, soft synthetic resin, etc. 2
A ring-shaped packing 12 shown in the figure is fixed such that its central through-hole corresponds to and communicates with the central through-hole of the packing support cylinder 11.

As shown in FIG. 2, the packing 12 includes a cylindrical inner tube 13 fitted to the lower end of the packing support tube 11, and a dish-shaped outer peripheral ring 14 disposed around the inner tube 13. The inner diameter of the inner cylinder 13 is equal to or slightly smaller than the outer diameter of the packing support cylinder, while the outer diameter of the outer circumferential ring 14 is set equal to the inner diameter of the protruding opening 4 of the container. Further, a notch 15 is provided in the annular portion of the outer circumferential ring 14 . The length of the packing support cylinder 11 is
While the packing 12 is being slid inside the ejection opening 4 of the container 1 and the impregnation piece support 7 is completely attached to the container 1, the outer ring 1 of the packing 12 is
4 protrudes slightly from the lower end of the projection opening 4, and is set to a length such that a portion of the notch 15 of the outer ring 14 is opened to the internal space of the container 1.

Further, on the lower surface of the impregnated piece support base 7, a lower support cylinder 16 having a diameter and a predetermined length that fits onto the protrusion 5 provided on the outer periphery of the neck 3 of the container 1 is provided.
are arranged so as to surround the packing support cylinder 11, thereby making it possible to more firmly attach the impregnated piece support 7 and the container 1.

Further, a liquid return hole 8 is bored in a portion of the impregnated piece support 7 located above the packing 12. Only the outer portion of the liquid return hole 8 is inclined toward the center. The number of liquid return holes 8 may be one or more. The upper surface of the impregnation piece support 7 around the reflux hole 8 is lowered in a fan-like manner to form a solution reservoir 21, as shown in FIG. It communicates with the reservoir 21'. 22 is an introduction rib.

Reference numeral 17 denotes an annular impregnated piece, which is mounted on the impregnated piece support 7 surrounded by the outer peripheral wall 18 of the impregnated piece support 7 and the cylindrical body 9 so as to close or block the small hole 10. . The impregnated piece 17 is made of a water-absorbing material, such as filter paper, natural fibers, synthetic fibers, etc.

Reference numeral 19 denotes a supply pipe of a predetermined length made of glass, synthetic resin, metal, etc., and one end thereof is formed in a U shape (or may be linear). The supply pipe 19 is U
The end of the shape is disposed in the cylindrical chamber 20 within the cylindrical body 9, and the other end is inserted into the central through-hole of the packing support cylinder 11 so as to be immersed in the solution within the container 1.

In such a configuration, a container 1 filled with a solution
Then, while sliding the outer circumferential ring 14 of the packing 12 on the inner circumference of the protrusion part 4 of the container 1, the impregnated piece support stand 7 is
is attached, the space inside the container 1 is compressed by the gasket 12, and the solution 2 is thereby supplied to the supply pipe 19.
It rises through the supply pipe 19 and drips into the bottom of the cylindrical chamber 20 from the U-shaped (or linear) end opening of the supply pipe 19.
The solution dropped onto the bottom of the cylindrical chamber 20 is absorbed by the impregnated piece 17 in the liquid passage hole 10 portion, and together with the liquid passage hole 10.
is in a sealed state by the solution film of the impregnated piece 17 in that part, and the cylindrical chamber 20 is kept in a slightly reduced pressure state by the volume absorbed by the impregnated piece 17. When the impregnated piece support 7 is completely attached to the container 1, the space inside the container 1 is formed by the notch 15 of the packing 12,
Since the air hole 6 at the upper end of the container outlet 4 and the gap between the protrusions 5 on the container neck 3 communicate with the outside air, the pressure becomes the same as atmospheric pressure, and therefore, the pressure is automatically adjusted by the siphon principle. Then, the solution is sucked up, dropped, and absorbed into the impregnated piece 17, and the solution is volatilized into the outside air while being diffused over the entire area of the impregnated piece 17. Note that the amount of solution volatilization depends on the exposed area of the impregnated piece 17, but can be adjusted by using a volatilization control lid as shown in FIG. can. supply pipe 19
If the inner diameter of the cylinder is too large, capillarity and cylindrical chamber 2
The siphon principle may not work depending on the degree of decompression in zero space, so the inner diameter of the supply pipe is usually 0.3~
5 mm, and the internal volume within the cylindrical body 9 is preferably selected within the range of 5 to 30 ^cm3 .

Once the above operation is performed, the siphon principle allows the solution to be sucked up, dripped, absorbed into the impregnated piece 17, and evaporated due to the relationship between the atmospheric pressure above the solution 2 and the negative pressure inside the cylindrical chamber 20. done automatically. Even if most of the solution is consumed and there is no solution 2 in the container 1, the inside of the cylinder 9, the impregnated piece 17, the retention parts 21, 21' of the impregnated piece support 7, and the supply pipe 1 will remain for a while.
Since the solution remains in the supply pipe 9, volatilization continues, and the solution in the supply pipe 19 is sucked into the cylindrical chamber 20 and drips. As the solution continues to volatilize, the supply pipe 19
As long as the solution remains within the cylindrical chamber 20, the interior of the cylindrical chamber 20 remains under negative pressure relative to the outside pressure.

However, when all the solution in the supply pipe 19 drips and disappears, air enters the cylindrical chamber 20 from outside the container through the supply pipe 19, and the pressure becomes equal to the external pressure. At this time, the solution remaining on the impregnated piece 17 including the inside of the cylinder 9 is not subjected to supply control by the siphon system, so if the liquid return hole 8 is not provided in the impregnated piece support 7, the solution inside the cylinder 9 Only a certain amount of liquid overflows from the impregnated piece support base 7 and falls onto the desk surface or table on which the container is placed, resulting in staining. This is because the impregnated piece 17 is already saturated with the solution.

On the other hand, when the liquid return hole 8 is provided in the impregnated piece support base 7 according to the present invention, the overflow liquid seeping out from the impregnated piece 17 passes through the introduction rib 22 from the liquid return hole 8 to the outer periphery of the packing 12. It is housed within the ring 14. At this time, the notch 15 provided in the outer ring 14 is filled with the overflowing solution. Therefore, even if there is no solution in the container 1 and in the supply pipe 19, as the solution is volatilized from the impregnated piece 17, the container 1
The entire inside and the inside of the cylindrical chamber 20 become under negative pressure, and the solution inside the packing 12 is sucked under negative pressure.
2 and the supply pipe 19 to be accommodated in the container 1. In this case, the supply pipe 19 is attached to the bottom of the container 1.
If a slope is provided so that the tip of the gasket 12 is located or facing the lowest part, or if a recess 23 is provided as shown in the figure, all the solution in the packing 12 can be contained in the container 1, especially in the recess 23. to seal the lower end opening of the supply pipe 19, and the gasket 12
When the notch 15 is in communication with the atmosphere, the solution in the recess 23 is transferred to the impregnated piece 1 again by the siphon principle.
7 and can consume the solution almost completely.

By the way, if the cylindrical body 9 is made of a transparent material, the dripping state of the solution can be visually seen and enjoyed.

FIG. 4 shows another example of the packing, and in this example, a small hole 24 is provided in the bottom surface of the outer ring 14a in addition to the notch 15 in the example of FIG. When using the packing shown in Fig. 4, the space inside the container 1 is in communication with the outside air even while the impregnated piece support 7 is being attached to the container 1, so a single attachment operation can only cover the required amount. The solution passes through the supply pipe 19 and enters the cylindrical chamber 2.
Since it is difficult to rise to within 0, it is necessary to repeat the mounting operation 2 to 3 times. Alternatively, the cylindrical body 9 may be pressed with a finger to aspirate and raise the solution. Note that if the diameter of the small hole 24 is large, no internal pressure will be applied to the inside of the container 1, and the rise of the solution cannot be expected.
It is preferable that the diameter of No. 4 is 0.5 mm or less.

FIG. 5 shows another embodiment of the volatilization container according to the present invention, and illustrates the state before use. This embodiment differs greatly from the embodiment shown in FIG. 1 described above in that a volatilization control lid is provided and an inner stopper is provided to prevent liquid leakage in the event of a fall. That is, an arbitrary number of openings 25 are formed at appropriate locations on the relatively high outer peripheral wall 18a of the impregnated piece support 7a.
On the other hand, an opening 27 of a predetermined shape corresponding to the opening 25 is provided at an appropriate location on the outer peripheral wall of the dome-shaped volatilization adjustment lid 26, or an opening with an appropriate opening area is further provided in the ceiling of the volatilization adjustment lid 26. 28 may also be provided. With this configuration, the volatilization adjustment lid 26 is placed on the impregnated piece support 7a, and the opening area is adjusted by rotating, so that the volatilization of the solution absorbed by the impregnated piece can be arbitrarily controlled. It becomes possible to adjust. Further, a fixed amount of volatilization is always performed through the opening 28 in the ceiling of the volatilization adjustment lid 26, and when a larger amount of volatilization is required, such as when the room where volatilization is required is large, volatilization adjustment is performed. Adjustment is possible by rotating the lid 26.

Further, an elastic tube 29 is fixed to the lower end of the supply tube 19, and the elastic tube 29 is attached to the packing support tube 11.
a and the center through-hole of the packing 12a. A thread is provided on the outer periphery of the opening 4a of the container 1, and an inner stopper 30 having a shape capable of accommodating the elastic tube 29 is screwed into the thread. By using such an inner stopper, there is no need for the solution to spill even if the container falls over before use, and the elastic tube can be protected during transportation. In addition, the lower support tube 16
A locking protrusion 31 is provided on the inner surface of the lower end of the container 1, and locking grooves 32 and 33 are provided on the outer surface of the upper and lower ends of the neck 3a of the container 1. By fitting, the container 1 and the impregnated piece support base 7a are joined. In use, after removing the inner plug 30, the impregnated piece support 7a is attached to the container 1 (at this point, the locking protrusion 31 of the lower support tube 16a fits into the locking groove 33).

Further, as shown in FIGS. 6 and 7, the impregnated piece support 7b also has openings 34 to promote volatilization.
may be provided. In FIG. 6, liquid return holes 8 are provided at two locations, and in place of the liquid passage hole 10 shown in FIG. By inserting a fiber bundle 39 of a water-absorbent material such as cotton or synthetic fiber into the bottom, the solution permeates and transfers smoothly from the cylindrical chamber 20 to the impregnated piece 17a. Also,
A reinforcing rib 35 is provided at the cylindrical body fitting portion.

FIGS. 8 to 11 show other embodiments, which are basically the same as those shown in FIG. 5, but differ in the shape and mode of the liquid return holes. In FIG. 8, the lower reservoir part as shown in FIGS. 1 and 5 is not provided, and the entire inner wall of the return liquid hole 8a is sloped, or as shown in the figure, the inner wall of the liquid return hole 8a is sloped, especially from the outside toward the center. It has a gentle slope. This has the advantage that excess solution can be collected more smoothly into the return liquid hole 8a. In addition, since a liquid film is relatively easily formed in the liquid return hole 8a, it is preferable to provide an introduction rib 22 so that the solution can flow down smoothly.

In FIG. 9, a plastic rod or the like 36 is attached to the inner surface of the liquid return hole 8, and its lower end is arranged so as to reach the bottom surface of the outer ring 14b of the packing 12b. The solution flows down the rod 36.
In this case, no lead-in rib is required. In FIG. 10, a short plastic tube 37 is fitted into the lower part of the liquid return hole 8 in a curved manner. A portion of the lower end of the tube 37 is cut away in the length direction to provide an opening. This allows the solution to flow down smoothly, and since the opening is provided at the bottom end, there is no need for air to remain in the middle of the tube and prevent the solution from flowing down. 1st
In Figure 1, a fiber bundle 38 made of cotton or glass wool is passed through the liquid return hole 8, the upper end of the fiber bundle 38 is pressed by the impregnated piece 17a, and the lower end is pressed down to the bottom surface of the outer ring 14b of the packing 12b. The fiber bundle 38 is stretched so that the solution flows down along the fiber bundle 38. In both cases of FIG. 10 and FIG. 11, no lead-in rib is required.

In the volatilization container according to the present invention, a heating element such as an electric heating plate is inserted between the impregnated piece and the impregnated piece support over the entire surface or a part thereof, and the impregnation is carried out by the heat emitted by the heating element. It is also possible to forcibly volatilize the solution absorbed by the pieces.

Effects of the invention As mentioned above, the present invention has two impregnated piece supports 7, 7.
When attaching a, 7b to the containers 1, 1a, the packings 12, 12a, 12b are configured to slide inside the protruding openings 4, 4a of the containers 1, 1a to compress the internal space of the containers, The solution is supplied into the cylindrical chamber by simply attaching the impregnated piece support to the container, and then the siphon principle automatically replenishes the solution, absorbs it into the impregnated piece, and volatilizes it from the impregnated piece. In addition to the basic effect of being extremely simple, one or more liquid return holes 8, 8a are provided at the upper part of the packing of the impregnated piece support.
Since this is provided, this constitutes an excess liquid return mechanism, and it is possible to obtain the effect that overflow of the solution to the outside of the system can be prevented, especially in the final stage of volatilization.

In addition, there are practical advantages such as the solution does not stain hands. In addition, because the siphon principle allows fresh solution to be constantly replenished in the container, it is possible to continuously supply a constant amount of components at all times, and the amount of volatile components decreases over time unlike traditional aromatic volatilization containers. There's no need to worry about it changing.
Furthermore, if the amount of volatilization of the solution is adjusted by rotating the volatilization adjustment lid, there is an advantage that the components can be volatilized efficiently and easily.
