という問題がある。2. Description of the Related Art Conventional fragrances have a target duration of fragrance of about one month and contain various fragrances having different volatility to maintain fragrance. After that, the quality of the scent changes greatly thereafter. On the other hand, a fragrance composition containing a large amount of highly volatile fragrance is suitable for a short-term use fragrance because the fragrance is volatilized in a short period of time. When the container is sealed with a heat seal, there is a problem that the sealing property is deteriorated such as delamination.

に拡散する。The fragrance 10 is suitable as a disposable lightweight fragrance, for example, for making a car or other small space into a fragrant atmosphere for a short time. That is,
The tab 16 is pinched, the rectangular film 13 is peeled off, the sealed body is opened, and the release paper covering the adhesive is removed in a state where the perfume emission opening 17 of about 1 to 10 cm 2 is formed. It is used by attaching it to the seat (fiber surface) or instrument panel part (polyvinyl chloride surface) in the car. Since the fragrance 10 is used for a short time, it is preferable that the fragrance 10 is light in weight of about 1 to 10 g. The strength of the adhesive may be weak and the sticking portion is not damaged. The liquid fragrance composition impregnated in the carrier 12 is excellent in volatilization properties, and therefore quickly diffuses through the fragrance volatilization opening 17 with an appropriate scent.
