A cartridge system for delivering an aqueous solution made with a mixture of an active material and a liquid medium, where the cartridge system includes a bottle-shaped container and a pump fastened to a neck of the container, where the container is filled with the liquid medium. The container includes a cartridge and an intake tube of the pump sealingly inserted in an upper side of the cartridge, where the active material is supplied to the cartridge through the intake tube. The cartridge is sealed from an exterior by a piston or a stopper, where the piston or stopper is movably arranged in a wall of the cartridge and configured to enter into an interior of the cartridge under reduced pressure produced by the pump and opens to the exterior of the cartridge so that the active material is mixable with the liquid medium.

Cartridge system for delivering an aqueous solution

A method of manufacturing containers consisting of a substantially stiff outer container and a readily deformable inner bag of first and second thermoplastic plastic materials, where the inner bag is detached from the wall of the outer container, includes the step of the excess material is supplied again to the first screw conveyor, which mixes the excess material with the first thermoplastic plastic material and supplies it to the extruder nozzle, wherein the first thermoplastic plastic material has a lower viscosity in the molten state than the excess material so that the outer layer of the extruded tube consists only of the first thermoplastic plastic material.

Method of manufacturing containers

The method for manufacturing a container having a substantially stiff outer container and a readily deformable inner bag of thermoplastic plastic materials which do not form a weld connection with one another, with a container opening and holes in the outer container, wherein the method includes forming holes in the wall of the outer container at diametrically opposed positions, which lie on the intersection line of a plane defined by the base seam and the longitudinal axis of the container with the container wall and that a pin-shaped tool forces the inner bag through the holes by a predetermined distance from the wall of the outer container and thereby detaches it from the wall, whereafter a pressure medium is introduced through the holes into the gap between the inner bag and the outer container, which detaches the inner bag from the wall of the outer container.
