Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a card-shaped aromatic body that has a card shape and emits a fragrance.

[Prior Art] Conventionally, as this type of card-like aromatic body, a plastic sheet into which a fragrance is kneaded is known. This fragrant plastic sheet is manufactured as follows.

The resin pellets mixed with the fragrance are heated to 80°C to 200°C in a reactor to dissolve them.

The melted plastic is then formed into a thin sheet, which is then immersed in a water bath to cool.

The thus obtained thin film-like sheet is laminated with another sheet whose surface is printed via an adhesive, and heated and pressed to form a single card.

The plastic sheet produced in this manner becomes fragrant due to the fragrance mixed into the thin film-like sheet being diffused into the surrounding area.

[Problems to be Solved by the Invention] When producing a plastic sheet with a fragrance as described above, there is a problem in that a considerable amount of fragrance is scattered because heat is applied when melting the resin pellets. The amount of fragrance lost varies depending on the type of resin, melting time, and melting temperature, but
The loss rate in normal cases reaches about 40-70%.

Furthermore, in the case of plastic sheets manufactured by the above-mentioned conventional manufacturing method, heat is applied to the fragrance during molding or adhesion, so that the fragrance is likely to change in quality due to the heat and the fragrance may be lost.

[Means for Solving the Problems] The card-shaped aromatic body of the present invention includes a card-shaped bag, at least a portion of which is breathable, and an clathrate that is fixed to the inner surface of the card-shaped bag with an adhesive. It has a powdery fragrance (hereinafter sometimes simply referred to as "powdered fragrance").

[Function] In the card-shaped aromatic body of the present invention, the fragrance generated from the powdery aromatic agent inside the bag passes through the air-permeable bag and diffuses to the outside.

This powdery aromatic agent is fixed to the inner surface of the bag body with an adhesive, so that it is not unevenly distributed in a part of the bag body, and the fragrance is reliably diffused to the outside of the aromatic body. Also,
Since this powdered fragrance is simply adhered to the adhesive layer on the inner surface of the bag, there is no need to heat it to high temperatures as in the past, and therefore there is no loss of fragrance or thermal deterioration of the fragrance during this adhesion process. is prevented, and the fragrance can be emitted for a long time.

Moreover, since the powdery fragrance according to the present invention is clathrated, it has excellent sustained release properties and can sustainably diffuse the fragrance over a long period of time.

[Examples] Examples of the present invention will be described in detail below with reference to the drawings.
