Liquid substance dispenser, has concentric tubes fitted with each other as inner and outer tubes in slidable manner, and foot and operating part exerting downward force on flexible container for compressing substance

摘要

The dispenser (1) has a flexible container for holding a liquid substance and surrounding a rigid sheath (4) comprising a foot (5) and an operating part (6) telescopically movable from each other. The foot and the operating part exert a downward force on the flexible container for compressing the substance by reducing the container volume. A flat bottom surface (8) has an upright tube (9) and a closing element (11) with concentric tubes (10), where the concentric tubes are fitted with each other as an inner tube and an outer tube in a slidable manner.
