A process for the production of containers for the mass production and device for carrying out the method.

摘要

The invention relates to a method for mass production of containers (37) for pourable products (liquid and powder materials). The container is designed so that the pouring of the products without mutual inclusion of air in the Füllproduktraum is possible. The container consists of at least two main components, wherein a main component forming the outer, carrying sleeve of the container and the other main component is the inner, flexible bag. The outer shell can be coated with an outer film. This outer film, preferably a thin plastic film, can be easily printed. This vessel is described, for example in the patent CH 696 198. The method which achieves this object is characterized in that in a first, sequential phase, the two main components of the container sequentially, synchronously and intermittently in feed lengths of formed "n" pieces and in two parallel paths that a web the outer shell and the other web accomplish the inner bag that at the end of the first sequential stage, the two webs are brought together to form the open container, that the first sequential phase is followed by a second, parallel-running phase in which the containers in "n" pieces grouped side by side to the filling and closing process are subjected to, and leave that in the third and final phase the containers for weight control and for conditioning the manufacturing process again sequentially. A great advantage of the method according to the invention lies in the high production rates that are made possible thereby. Based on a cycle time of one second 6 liters per second or nearly 22,000 liters can be packed and conditioned per hour. Further advantages are the space-saving and compact design of the device, which are made possible by the method.
