2. Description of the Related Art Conventionally, as this type of device, a core rod is inserted from the mouth of a plastic bottle containing a volatile liquid, a part of the core rod is immersed in the liquid, and the head of the core rod is screwed into the bottle mouth. In some cases, the bottle is protected by a cap, and the bottle is provided with a ventilation window on the peripheral wall and an external cap fitted with a disk (pad) made of a porous material inside (Japanese Patent Laid-Open No. 61-90).
666). When using, remove the outer cap and then the inner cap, and then fit the outer cap again to adhere the end surface of the core rod to the disc, and the liquid that has been sucked up to the core rod by the capillary phenomenon is removed from the disc with a large surface area. Volatilize and diffuse through a ventilation window.

[0003]

The conventional device is of a type that discards the bottle when the volatile liquid is exhausted, which is not preferable in terms of resource saving. In terms of manufacturing, the bottle main body as well as the inner and outer caps and the core There is a problem that the number of parts such as a rod is large and the cost is high because it takes a long time to assemble. In addition, when using it, it is necessary to remove and replace the inner and outer caps as described above, and when not in use, it is necessary to perform a troublesome operation such as covering the inner cap in the reverse procedure, and functionally replacing the air inside the bottle. If it was not carried out smoothly, there was a problem that uniform volatilization could not be expected. The present invention has been made by focusing on the above problems,
It is a storage type that can be used repeatedly just by exchanging the pouch enclosing a volatile liquid. It can be manufactured at low cost with a small number of parts and assembly steps, and it is extremely easy to handle and a uniform volatile state can be obtained. An object is to provide a diffusion device for a volatile liquid.

[0004]

According to a first aspect of the present invention, there is provided a device for diffusing a volatile liquid, wherein the pouch is filled with a volatile liquid such as a fragrance, and the pouch has a ventilation hole. And a pouch case that holds and holds the volatile liquid in an upright or inclined posture, and the pouch has a core body for discharging the volatile liquid inside to the outside by a capillary action, and the volatile liquid drawn out by the core body is the pouch. The structure is characterized in that it is volatilized from the ventilation holes of the case. In addition, a pad is provided on the pouch case so as to face the ventilation hole, and the volatile liquid led out by the core is volatilized through the pad . Further, it is practical that the pouch case is composed of a case main body for accommodating the pouch and an openable / closable lid (claim 2 ).

[0005]

[Operation] When, for example, one end of the pouch is opened to expose the core, the volatile liquid inside is sucked up by the capillary action of the core and discharged to the outside, where it volatilizes and diffuses from the ventilation hole of the pouch case. , Give the atmosphere the desired aroma. When a pad is provided facing the ventilation hole of the pouch case, the volatile liquid led out by the core is diffused through the pad having a large area, so the diffusion speed is also large and uniform diffusion is achieved over a wide range. Be seen. Also, by configuring the pouch case with two parts, the case body and the lid that can be opened and closed,
It becomes easy to put on and take off the pouch and to make the case. When the volatile liquid in the pouch is exhausted, it can be removed from the pouch case and replaced. The handling is extremely simple and the number of parts is small, so it can be manufactured at low cost. Further, the pouch made of a plastic film or the like shrinks as the volatilizable liquid volatilizes and shrinks, so that air replacement in the pouch is not necessary and uniform volatilization is performed.
