Pressing mechanism for conveying cosmetic and writing pens

摘要

The mechanism comprises an inner part (2) which lies in an approximately opposite lying areas (13) of the inner wall of a tubular formed part (1). The tubular part is elastically deformable and holds the inner part. The degree of elastic deformability of the tubular part is such that itself and the inner part are matched with each other. By applying pressure (D) to approx. opposite outer areas (X) of the tubular part, between the areas (13) and the inner part, the tubular part is deformed. This releases the inner part as it is no longer held by the inner wall.
