It is disclosed in Patent Document 2 that the roll screen installed on the window frame for shading from the outside is composed of a synthetic resin sheet to which a deodorant is added. However, in those sheets in which the deodorant or the like is retained, the period during which the effect of the deodorant is maintained is very short compared to the durability of the sheet, and they are effectively used for a long period of time. There is a problem that it cannot be done.

On the other hand, for example, in the screen door disclosed in Patent Document 3, a large number of through holes are provided in the frame of the screen door provided with an insect repellent net, and the through holes are provided with insect repellent, fragrance, deodorant or deodorant. A gas generator that generates the effective gas is accommodated, and ventilation windows are detachably provided on both sides of the through hole. The screen door of Patent Document 3 is excellent in that the screen door can be effectively used for a long period of time by sequentially filling the through holes of the frame body with the gas generator, but the storage of the screen door when not in use, etc. No consideration has been given. Moreover, it is not easy to sequentially replenish the gas generators in the large number of through holes in each screen door, and it is desired that consumables can be replenished by a simple operation.
