沢を生じさせたものである。In general, cosmetic containers are required to have chemical resistance, fragrance retention, mechanical strength, and thermal strength, and containers that meet these requirements are made of synthetic resins such as polypropylene and polypropylene terephthalate (hereinafter referred to as rPETJ). Widely used. And in specific application fields,
Furthermore, cosmetic containers are required to have excellent decorative properties, and cosmetic containers having a frosted-glass luster are used as one such container. Such frosted glass cosmetic containers are generally manufactured by so-called blow molding using a synthetic resin molding material that can form transparent synthetic resin moldings, and are then subjected to post-processing such as sandblasting, etching, or brush painting. When molding by blow molding, the inner surface of the mold is sandblasted or corroded in advance, and an uneven pattern is transferred to the surface of the cosmetic container to be molded, giving it a frosted-glass luster. This is what caused this.

成樹脂体を取り出しにくいという問題が生じていた。However, in order to produce a frosted-glass gloss as described above, it is necessary to form the surface irregularities quite deeply, which can cause the surface of the cosmetic container to become rough or scratched, and also to make it feel unpleasant to the touch. Ta. moreover,
Since post-processing steps are required, manufacturing becomes difficult. Additionally, if the inner surface of the mold is subjected to treatments such as sandblasting or corrosion processing, the surface of the synthetic resin body may be damaged or it may be difficult to remove the synthetic resin body from the mold. was occurring.
本発明は、このような事情に鑑みなされたもので、表面

粧品容器の製法を第２の要旨とする。In order to achieve the above object, the present invention provides a cosmetic container 1 having a frosted glass luster and constructed by blow molding a synthetic resin molding material.
The first aspect is a cosmetic container having a frosted glass luster, characterized in that an inorganic powder 3 having a particle size of 20 μm or less is dispersed in a transparent synthetic resin 2 constituting the container in an amount of 10% by weight or less of the total weight, A ground glass-like material characterized by mixing transparent synthetic resin 2 with a synthetic resin molding material that can constitute a molded body, inorganic powder 3 having a particle size of 20 μm or less in an amount of 10% by weight or less of the total, and blow-molding this mixture.

見いだし、本発明に到達したのである。In other words, in order to obtain a cosmetic container that is hard to scratch, has a good texture, and has a frosted-glass luster, the present inventors believe that instead of forming unevenness on the surface of the cosmetic container as in the conventional example, We conducted a series of studies based on the idea that it would be effective to intersperse resin and highly staining inorganic powder in the synthetic resin that makes up the container. As a result, they discovered that when inorganic powder with a small particle size is mixed with a synthetic resin molding material for forming a transparent synthetic resin molded object, and this mixture is blow-molded, the above-mentioned frosted glass gloss appears. It was reached.
つぎに、本発明の詳細な説明する。Next, the present invention will be explained in detail.

を第１図に示す。The cosmetic container of the present invention can be obtained, for example, as follows. First, transparency (including not only completely transparent but also semi-transparent)
A spherical powdered calcium carbonate with a particle size of 20 μm or less is added to a PET resin liquid at a high temperature that can form a synthetic resin molded product in an amount of 10% by weight or less (hereinafter abbreviated as "%"), and thoroughly mixed. and dispersed in the PET resin liquid. This mixture is then extruded from an extruder to form a cylindrical parison,
While the parison is still soft due to heat, the parison is sandwiched between a two-split mold whose inner wall has the shape of the desired cosmetic container, and air is blown into the parison to inflate it and form it. Then, after cooling, the mold is opened and the molded product is taken out. Obtained molded product (hollow cosmetic container)
is shown in Figure 1.

せる。この白濁によって、ＰＥＴ樹脂がスリガラス調の
光沢を呈するようになる。This cosmetic container 1 consists only of a container body without a lid, has a smooth surface, and has a frosted glass appearance. This gloss is caused by the fact that the synthetic resin forming the cosmetic container 1 has a cross-sectional structure as shown in FIG. That is, during molding, when the molten PET resin 2 containing powder calcium carbonate 3 flows in the direction of the arrow, the powder calcium carbonate 3 is scattered in the flow, and in this state the resin hardens to form a cosmetic container. Ru. Therefore, the powdered calcium carbonate 3 becomes small white spots scattered throughout the cosmetic container 1, and makes the originally transparent PET resin 2 cloudy. This cloudiness causes the PET resin to exhibit a frosted-glass luster.

光沢が得られる。この場合は、化粧品容器の表面に形成
される凹凸の深さを少なくすることができる。Such ground-glass gloss can be efficiently obtained when the shape of the powdered calcium carbonate 3 is spherical or elliptical, without corners, as shown in FIG. That is, when the powder calcium carbonate 3 is, for example, a rectangular powder, a vacuum space is likely to be formed in the shadow of the powder when viewed from the flow direction of the resin liquid during molding, and this vacuum space is used for cosmetics. The refractive index of light that enters the container 1 and is reflected is changed to generate diffused reflection. For this reason, the surface of the cosmetic container 1 shines and has a pearl-like luster, and the above-mentioned ground-glass luster cannot be obtained. Therefore, in order to obtain a frosted glass gloss, powder calcium carbonate 3
is preferably spherical or nearly spherical, and is preferably contained in a relatively small amount in the molded article. Although a ground glass gloss can be obtained by the method described above, a deeper ground glass gloss can be obtained by further performing sandblasting or corrosion processing as in the conventional example. In this case, the depth of the unevenness formed on the surface of the cosmetic container can be reduced.

％以下に設定する必要がある。In the above explanation, PET resin is used as the synthetic resin molding material used for the cosmetic container 1, but any material can be used as long as it has the chemical resistance, fragrance retention, mechanical and thermal strength required for the cosmetic container. Anything is fine. In addition to the above-mentioned calcium carbonate, examples of inorganic powder include talc, kaolin,
Silica, titanium, etc. can be used, and these may be used alone or in combination. However, these inorganic powders must have a particle size of 20 μm or less;
If it exceeds 0 μm, a ground glass gloss cannot be obtained. In addition, the amount of inorganic powder used is 10% of the total depending on the gloss.
Must be set to % or less.
この範囲を外れるとスリガラス調の光沢が生じない。Outside this range, frosted glass gloss will not be produced.

とにもなり、好適である。Note that among the above powders, the above calcium carbonate and talc are inexpensive materials that can also be used as fillers, and the use of these is preferable since it also reduces the manufacturing cost of cosmetic containers.
つぎに、実施例について説明する。Next, examples will be described.

ができるようになることから、製造コストを下げること
ができるという効果をも奏する。As described above, the cosmetic container of the present invention is obtained by mixing 10% or less of inorganic powder with a particle size of 20 μm or less into a synthetic resin molding material for forming a transparent synthetic resin molding, and blow molding this mixture. The molded product is made cloudy by scattering inorganic powder in a transparent synthetic resin, giving the surface a frosted-glass luster. Therefore, there is no need to apply matte processing or treatments such as sandblasting or corrosion processing to the mold, or to perform post-processing on the molded cosmetic container to form irregularities on the surface of the cosmetic container, as in the past. Therefore, the surface of the cosmetic container is smooth, resistant to scratches, and has a pleasant texture. Furthermore, since the number of processing steps is reduced and inexpensive materials can be used, manufacturing costs can be reduced.
