УСТРОЙСТВО ДЛЯ РАСФАСОВКИ И ДОЗИРОВАНИЯ ВЕЩЕСТВА, В ЧАСТНОСТИ, В ВИДЕ КОСМЕТИЧЕСКОГО СРЕДСТВА

摘要

The moving component (20) has an upper lip (25). This seals against the internal wall, when moving between positions. During first use, this isolates a fraction of the product, and compresses it, forcing it to leave through the distribution opening (7). When actuation ceases, the moving component returns. This is accompanied by entry of air into the container (2).
