  As for the containers of chemicals such as fragrances and deodorants, synthetic resin molded products (in many cases, blow molded products) are used, as in the examples described in Patent Documents 1 and 2. Therefore, there is a problem that the disposal as waste is troublesome and also increases the distribution cost.

  Moreover, in the system which inverts the container which put the liquid volatile chemical | medical agent like the thing of patent document 1, the supply body which consists of a container, the volatilization body of a porous material, a resin injection molding, etc., a base, a cover, a container This requires many parts, such as a cap to support, increasing the number of assembly steps and increasing the cost. Management of parts is also complicated.

  In the method of inverting a container containing a gel-like volatile drug like the one described in Patent Document 2, as the exposed part of the volatile drug shrinks / decreases over time, the volatile drug in the container Descends by its own weight, and a new part is exposed. However, the volatilizing drug is a single gel, and the contraction of the gel due to the volatilization of the drug is affected by the temperature and air flow, so that the movement of falling down by its own weight and exposing new parts occurs at a constant rate. It is difficult to keep the volatilization effect constant throughout the entire period of use.

  The present invention has been made in view of the above problems, and an inverted container that enables stable supply and automatic supply of a drug by making the form of a volatile drug into a granular gel or solid drug bead. In this way, the volatile agent is overcome in the liquid or single gel form. In addition, it provides a chemical volatilization device that is easy to assemble and provides a certain chemical volatilization effect throughout the entire period of use, and at the same time, can supply volatile chemicals in containers that are not bulky during distribution or disposal. For the purpose.

In order to achieve the above object, in the present invention, a bead supply container containing granular gel or solid drug beads containing a volatile drug component, a bead receiving port to which a bead outlet of the bead supply container is connected, and the volatilization In a chemical volatilization apparatus comprising a volatilization chamber having a vent hole for volatilizing a chemical drug component, the bead supply container is a laminated pouch with a gusset having a bead outlet in the upper center, and the bead outlet is a male screw part at the tip A screw cap is screwed into the male screw portion, the bead receiving port of the volatilization chamber faces upward, and the male screw portion of the bead outlet is screwed into the inner surface of the upper end of the bead receiving port. The bead supply container is in an inverted state, and the bead outlet is in the state in which the screw cap is removed. Is intended to be screwed in over's inlet, the bead supply container is intended to be supported in a suspended in pouches stand on the inverted state, the flowing into the vaporization chamber through the bead outlet from the bead supply container The drug beads volatilize the drug component in the air, and the quantitative decrease of the drug beads in the volatilization chamber is compensated by the new drug beads coming down from the bead supply container.

According to this configuration, since the volatile drug component is supplied in the form of granular gel or solid drug beads, it is easier to handle and volatilizes than those supplied in the form of liquid or single gel. Minutes can be replenished smoothly. The drug beads can be smoothly transferred to the volatilization chamber, and it is easy to use up all the drug beads in the bead supply container. Accordingly, a certain chemical volatilization effect can be obtained throughout the entire use period. Assembly of the volatilization device is also simplified. Furthermore, since the bead supply container is in the form of a pouch with a gusset, it is easy to pack in a carton case, and the logistics cost can be reduced. Also, when the drug beads are used up and discarded, the volume of the bead supply container can be reduced by crushing or rolling the beads, which is easy to handle.

According to this configuration, the bead supply container can be supported so as not to fall down to the end .

  According to the present invention, in the drug volatilization apparatus, the container for supplying the drug beads is made into a pouch shape, so that it can be easily packed in a carton case, and when discarded, the volume can be reduced by crushing or rolling. Can be enjoyed.

  Hereinafter, 1st Embodiment of the chemical volatilization apparatus which concerns on this invention is described based on FIG. FIG. 1 is a schematic vertical sectional view of a chemical volatilization apparatus in which a bead supply container is set, and FIG. 2 is a perspective view of the bead supply container.

  The chemical volatilization apparatus 1 includes a volatilization chamber 10 and a bead supply container 20 connected thereto. The volatilization chamber 10 is composed of a planar circular tray 11 and a dome-shaped lid 12 that covers it. An annular peripheral wall 13 rises from the edge of the tray 11. The upper part of the annular peripheral wall 13 is slightly recessed, and the lower end of the lid 12 covers the recessed portion from the outside to form a seal fitting.

  The lid 12 has a lattice-shaped air vent 14 formed around the entire periphery. The vent hole 14 is for volatilizing a volatile drug component, and each opening constituting the vent hole 14 has a size that prevents a drug bead described later from passing through.

  A bead receiving port 15 is formed at the center of the lid 12. The bead receiving port 15 is a cylindrical portion protruding right above, and a female screw portion 16 is formed on the inner surface of the upper end.

  The bead supply container 20 is constituted by a pouch 21 made of a laminate film. The pouch 21 is made of a laminated film in which several layers of aluminum foil and synthetic resin layers are stacked to improve gas barrier properties, and is finished in a gusseted shape shown in FIG. A cylindrical bead outlet 22, which is an injection molded product of synthetic resin, is inserted into the upper center of the pouch 21, and the portion serving as the contents entrance and exit, and the pouch 21 and the bead outlet 22 are welded in an airtight manner. An outer flange 23 is formed in the middle of the outer surface of the bead outlet 22, and a male screw portion 24 is formed at the tip.

  The outer flange 23 regulates the insertion depth of the bead outlet 22 into the pouch 21 and also serves as a knob for lifting the pouch 21. A screw cap 25 (see FIG. 2) is screwed into the male screw portion 24. The male screw portion 24 after the screw cap 25 is removed is screwed into the female screw portion 16 of the bead receiving port 15.

  The pouch 21 has a seal portion on the side where the bead outlet 22 is located and on the opposite side. A through hole 26 is formed in the center of the seal portion opposite to the bead outlet 22.

  The bead supply container 20 is filled with a large number of granular gel or solid drug beads 27 containing a volatile drug component. The drug bead 27 is a gel or powder material containing a volatile drug component such as a fragrance, a deodorant, an insect repellent or the like in the form of a small sphere. After the bead supply container 20 is filled with a predetermined amount of the drug beads 27, the tip of the bead outlet 22 is sealed with a seal member (not shown), the screw cap 25 is screwed onto the male screw portion 24, and finally the whole is shrink-wrapped. Completed form.

Is inserted into the bead receiving port 15. Then, the male screw portion 24 is screwed into the female screw portion 16. Then, the drug beads 27 flow into the volatilization chamber 10 through the bead outlet 22. The drug beads 27 entering the volatilization chamber 10 volatilize the drug component in the air. The air containing the drug component flows out from the vent hole 14 and is diffused into the room.

  The volume of the drug bead 27 decreases as the drug component volatilizes. The quantitative decrease in the drug beads 27 in the volatilization chamber 10 is compensated by the new drug beads 27 descending from the bead supply container 20. It is preferable to obtain the optimum relationship between the diameter of the drug bead 27 and the diameter of the bead outlet 22 through experiments so that the drug bead 27 descends smoothly.

  When the drug beads 27 in the bead supply container 20 are used up, the used bead supply container 20 is removed and replaced with an unused one. The used bead supply container 20 can be discarded after being crushed or rolled to reduce the volume.
