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).

A package for a water-soluble pulverulent or granular product comprising an inner container for said product formed from a flexible tube of a water-soluble film having two ends, each of said ends being closed by a transverse joint located near each end, and each of said ends being provided with an end strip, characterized as an extension of the flexible tube from said transverse joint to said end, one of said end strips having a perforated tear line therein intermediate the transverse joint and said end; an outer container surrounding said inner container with product, said outer container being formed from a flexible tube of a water-resistant material having two ends, each of which is closed by a transverse joint placed near said end; and wherein each end of said inner container is attached to the outer container at each transverse joint of said outer container. A device for the manufacture of a package of a water-soluble pulverulent or granular product comprising a first filling pipe, means for providing a metered supply of product to said first filling pipe, means for placing around said first filling pipe a first continuous flexible tube of film, first sealing means for making a transverse joint across said first tube to form a package while leaving a first end strip, filling means to deposit a measured quantity of said product in said package, means for closing said package by making a transverse joint in said first tube above said product while leaving a second end strip in said first tube, and perforating means for making a tear line in the second end strip; and a second filling pipe for receiving the filled and closed first tube, means for placing a second continuous tube of film around the second filling pipe, and sealing means for forming a transverse joint across both the first and second tube at each end of the first tube. A method of manufacturing a filled package in which a water-soluble pulverized or granular product is contained in a closed water-soluble inner container placed inside and attached to a closed water-resistant outer container comprising the steps of: (a) forming around a filling tube a first continuous flexible tube of water-soluble film, (b) forming a transverse joint across the tube below the filling tube to form a first closure in the first tube, (c) filling the first tube with a metered amount of the product; (d) forming a second transverse joint to seal said first tube and to provide an end strip therein; (e) perforating the end strip to form a tear line therein; (f) forming a second continuous flexible tube of water-insoluble film around the first tube; and (g) forming first and second transverse joints across the first and second tubes to provide closures to the second tube, while at the same time attaching the ends of the first tube to the second tube.
