    摘要: The object of the invention is a container (1) especially for chemical substances consisting of a substance chamber (2) of tubular plastic film (10) and a funnel-shaped headpiece (3). The film consists of low-density and the headpiece of high-density plastic. The tubular plastic film (10) is secured in the headpiece (3) by pressing. The headpiece (3) may be divided into a plate-shaped (4) and a tubular (5) section. On the side towards the substance chamber, the plate-shaped section (4) has an annular groove. The plastic film (10) is pressed into place by a securing ring with a U-shaped cross-section which can be pressed into the annular groove. A snap mechanism holds the securing ring firmly in the groove. The tubular plastic film (10) is firmly pressed between the securing ring and the groove walls. The container (1) can be closed at the rear by a suitable closure device.
