Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aromatic liquid container filled with an aromatic liquid, and more particularly to a container for an aromatic liquid used in a heating and evaporating apparatus for evaporating an aromatic liquid by heating using a liquid absorbing core. More specifically, the present invention relates to an aromatic liquid container which is not affected by any of the aromatic liquids containing various fragrances, and which is not adversely affected by altering the fragrance of the aromatic liquid.

[0002]

2. Description of the Related Art Heretofore, there have been known liquid-type fragrances of a normal temperature evaporation type and a heat evaporation type. In these containers, synthetic resin is mainly used as the material, and the type of synthetic resin used for the container is usually polypropylene (PP) or polyethylene terephthalate (PE).
T).

[0003]

In recent years, it has been considered that it is necessary to select a solvent suitable for the fragrance in order to maintain the fragrance of the fragrance liquid for a long period of time. Is limited to one type. However, when the container for filling these aromatic liquids is made of a synthetic resin, depending on the type of the fragrance or the type of the aromatic liquid containing the solvent, problems such as turbidity or swelling of the container due to the filling may occur. There were some fragrances and solvents that could not be used due to the problem. In particular, a resin container for filling the fragrance liquid preferably has properties such as high transparency, a high refractive index, and brilliancy to give a sense of quality, and thus has such properties. Although the resin of the material is extremely limited, it is difficult to additionally provide that a certain fragrance can be maintained. For this reason, when using containers made of synthetic resin as containers for filling various aromatic liquids, it has been difficult to cover a single type of container. Further, in the case of the heat-evaporation type fragrance, there is a problem that the selection of the material is particularly important because a high-boiling solvent is used. In particular, when the aromatic liquid is a perfume, since the contents are taken out and used, the flavor changes when the perfume is adsorbed by the container. Further, when the aromatic liquid is water-based, the balance is lost and the liquid becomes unstable.

[0004] Further, the PP or PET container has a high solvent resistance, a high degree of transparency, and a high moldability, so that it is practical, but has low heat resistance.
At 60 ° C., the latter deformed at 70-80 ° C., and could not be used for a heat evaporation apparatus. On the other hand, various thermoplastic resins can be used as the material of the hollow container,
As such a thermoplastic resin, polystyrene, acrylic resin, and the like have been known for a long time, and an example in which polyethylene naphthalate (PEN) is used for a container is also known. The conventional technology using PEN for a container is that the polyethylene-2,6-naphthalate exhibits excellent heat resistance compared to PET and has low permeability to water, carbon dioxide, oxygen and nitrogen. Further, it is only known that vitamin Bs and sulfa drugs do not discolor even when an aqueous solution of the vitamin Bs or the sulfa drug is stored for a long period of time, and the above-mentioned problems due to the substances to be added are not considered.

The present invention has been made in view of such conventional problems, and has as its object to provide an aromatic liquid container which is not affected by any of the aromatic liquids containing various fragrances. I do.

[0006]

Means for Solving the Problems The present inventors have conducted intensive studies in order to solve the above-mentioned problems, and as a material of the container, PEN is softened or whitened even by an aromatic liquid containing various fragrances. The present inventors have found that they do not cause turbidity as well as that they do not cause turbidity, and have completed the present invention.
That is, the present invention has solved the above problem by the following means. (1) A container for an aromatic liquid, wherein the resin is a polyethylene naphthalate in a container made of a resin filled with the aromatic liquid. (2) The fragrance liquid container is a fragrance liquid container in which a part of the liquid absorbent core is exposed outside the container, and a lower part of the liquid absorbent core is immersed in the aromatic liquid. The aromatic liquid container according to the above (1), wherein the upper part of the absorbent core is heated to evaporate the aromatic liquid for use. (3) The fragrance in the aromatic liquid is geraniol, limonene,
The aromatic liquid container according to the above (1) or (2), which is any of linalool.
