Abstract

PROBLEM TO BE SOLVED: To solve problems that a cosmetic such as a cream or a plaster comprising a perfume acting on human mental conditions such as quite sleep or prevention of sleepiness is not capable of sufficiently volatilizing the contained perfume and the fragrance of the perfume extends to surrounding persons other than a user without a distinction. SOLUTION: This aromatic plaster is obtained by forming a support hardly permeating an alcohol or the perfume on the undersurface of a liquid absorbing sheet having liquid absorptivity, forming an adhesive layer on the undersurface of the support, impregnating and holding a required amount of the perfume in the liquid absorbing sheet, preventing the perfume from migrating to the adhesive layer by the support, surely holding the required amount of the perfume and effectively, volatilizing the perfume. The liquid absorbing sheet is impregnated and held with a substance consisting essentially of a top note-based perfume. Thereby, the fragrance extends to persons requiring the fragrance and retention of a lingering scent is prevented to reduce influences on surrounding persons.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aromatic patch, and in particular, due to remarkable stress from the environment in daily life, excessive concentration required, insomnia as a reaction thereto, or hypnosis, continuation of tension. The present invention relates to an aromatic patch for eliminating or alleviating the like by the fragrance of a fragrance.

[0002]

2. Description of the Related Art Aromas have been used to sleep, relax, prevent drowsiness, and promote mental enhancement, for example, by burning incense. In addition, a pillow containing a dried product of a herb is used, and a herb tea is drunk. In recent years, cosmetics such as cream mixed with a fragrance have been applied and massaged, and a substance holding a fragrance in an adhesive layer of a patch has been applied.

In the above-mentioned cosmetics, since the fragrance is directly contained in the cosmetic, it is not possible to volatilize all of the fragrance, and the fragrance must be contained in a larger amount than is actually required. It is uneconomical, and has the drawback that the desired function can actually be obtained with the required amount of fragrance, but the fragrance lasts longer than necessary. In addition, since the adhesive layer contains a fragrance in the adhesive material, the fragrance is difficult to volatilize, and the fragrance must be added to the adhesive more than necessary, and the adhesive layer is directly applied to the skin. Because the fragrance comes into direct contact with the skin,
The fragrance that can be used may be limited, and the practical effect may be reduced.

[0004] Furthermore, in the prior art, even if only one person tries to obtain the above-mentioned various functions by the fragrance, the fragrance is distributed throughout the room, and the person who does not need the fragrance of the fragrance is required. Often, it was difficult to use unnecessary scents individually and without disturbing others in many cases.

[0005]

SUMMARY OF THE INVENTION The object of the present invention is to ensure that a necessary amount of a fragrance which acts on the mental state of a person such as sleep and sleepiness is held in a necessary amount, and that the fragrance can be sufficiently volatilized in use. Another object of the present invention is to obtain an aromatic patch which has as little effect as possible on people other than the user.

[0006]

According to the present invention, a liquid-absorbent sheet having a liquid-absorbing property is impregnated with a required amount of fragrance and held on the lower surface of the liquid-absorbent sheet so that alcohol and fragrance are hardly permeated. Form the body, to form an adhesive layer on the lower surface of this support, to prevent the transfer of the fragrance to the adhesive layer by a support interposed between the liquid absorbing sheet and the adhesive layer, Ensure that the required amount of fragrance is retained and effectively volatilized.

[0007] In addition, a fragrance impregnated and held in the liquid absorbing sheet is mainly composed of a top note type fragrance, and a fragrance of a required specific fragrance is distributed to a person who needs the fragrance. The fragrance is not diffused around as much as possible, so that the fragrance does not remain in the room more than necessary.

[0008]
