Abstract

A continuous process for producing water soluble containers, comprises forming a water soluble film material to create a container, and filling the container with a material, eg detergents, cosmetics, pharmaceuticals, etc. A water soluble film web is applied to the filled container, and the container is then sealed and finished off. Negative pressure is generated in the container during the process, by allowing the air trapped between the material and the film to escape through openings in the water soluble film web. The material filled is either in solid or liquid form. Forming of the film is by injection moulding or deep drawing.

Description

object The present application is a packaging method for consumer goods. Especially This application discloses methods of packaging consumer goods water-soluble Packaging materials.

The Deforming the water-soluble Material in step a) of the method according to the invention is preferably carried out by injection molding or casting or thermoforming.

"Injection molding" refers to forming a molding composition such that the in a mass cylinder for more as an injection molding process contained mass under heat plastically softened and pressurized through a nozzle into the cavity of a previously enclosed tool flows. The process is mainly at not curable Applied molding compounds that solidify in the tool by cooling. The injection molding is a very economical modern process for producing non-cutting shaped objects and is particularly suitable for the automated mass production. In practical operation, one heats the thermoplastic molding compounds (powders, granules, cubes, pastes and others) up to the liquefaction (up to 180 ° C) and then injected under high pressure (up to 140 MPa) into closed, two-part, that is from die (former die) and Kern (formerly Patrize) existing, preferably water-cooled molds, where they cool and solidify. Can be used piston and screw injection molding machines.

As "deep drawing" thereby procedures in which a film material by pressure under Forming a trough or receiving chamber is deformed. The pressure effect can, for example, by the action of a stamp, through Influence of compressed air and / or by the action of a negative pressure respectively. The pressure effect can be through two parts of a tool done, which behave as positive and negative to each other and deform a film placed between these tools as they are compressed. As a compressive force but also the weight of a suitable the top of the foil spent active substance. Preferably takes place the deformation into a matrix shape, which is the final spatial form the resulting trough or receiving chamber and the reproducible, Production of defined spatial forms allows. Especially preferred in the context of the present application are methods in which the film material by the action of a negative pressure in the trough a thermoforming die is formed.
