Abstract
Description
上記構成において、皮膚効能成分は親水性材料からなるものであってもよい。
本実施の形態で用いたポリプロピレン粉末、ポリエチレンオキサイド粉末、および、ヒアルロン酸粉末の平均粒径は177μmである。
表1は、ヒアルロン酸の滲出効果を確認するための試作条件とその結果を示す。
図1に示した本実施の形態の板状成形体1と同じ製造方法を用いて、かっさを作製した。図4Aは、本実施例で作製したかっさを示す斜視図である。図4Bは、図4Aに示すB-B線に沿って切断した断面図である。かっさとは、一般的には天然石や牛の角からできたプレート形状のものをいうが、本実施例では樹脂を成形することにより作製した。
これらの結果を表2に示す。
実施例2は、本実施の形態にかかる皮膚用樹脂成形体を用いた顔用マッサージ器について説明する。なお、顔用マッサージ器が皮膚接触型美容器具に該当する。図5Aは本実施例にかかる顔用マッサージ器を示す斜視図である。図5Bは、図5Aに示す皮膚を押し叩くように接触するマッサージ部の断面図である。このマッサージ部が皮膚用樹脂成形体により形成されている。
本実施例では、図6Aから図6Cに示すような美顔ローラー30について説明する。図6Aは、本実施例にかかる美顔ローラーを示す全体斜視図である。図6Bは、ローラー31の中心点を基準に切断した断面図である。図6Cはローラー31の表面部31aの一部拡大断面図である。
なお、本実施例ではローラー31の表面部31aに凹凸を設けた構造としたが、凹凸のない滑らかな球形状であってもよい。
本実施例では、図7Aから図7Cに示すような美容液容器40に用いた例について説明する。
使用後は、塗布ボール41の表面をふき取り、美容液容器40を立てて保持すれば、塗布ボールが乾燥するので安定に保存することができる。
なお、本実施例では、塗布ボール41の表面部41aに凹凸を設けた構造としたが、滑らかな球状の形状としてもよい。
本実施例では、図8Aおよび図8Bに示すような薬液吐出器50に用いた例について説明する。
図8Aは、本実施例にかかる薬液吐出器50を示す全体斜視図である。図8Bは薬液吐出器50の先端部に設けた吐出部51の断面図である。
