Abstract
Some chemical products are so toxic that they must not come into contact with parts of the human body. A package of such a construction that during filling and transport thereof and during the release of product therefrom, the risk of anyone coming into contact with the product is restricted to a minimum, is characterized in that the product is situated in a closed inner container (1) consisting of a water-soluble flexible material, and that the filled inner container is placed inside a closed outer container (2) consisting of a flexible material which is resistant to water, both the inner container (1) and the outer container (2) consisting of a flexible tube which is closed near the two ends by a transverse joint (4 or 5 respectively) and the end strips (6) of the inner container are connected to the joining strips (5) of the outer container in a manner such that between the contents of the inner container and the said joining strips there is a certain distance, and that a tear line (7) is made in an exposed part of one of the end strips (6) of the inner container (1).
