  • Publication number: 20090056760
    Abstract: A device having a reservoir that has an opening, a dosing chamber, and a movable conveying tool. The reservoir, the dosing chamber, and the conveying tool are disposed so the dosing chamber can be filled via the opening in the reservoir in a first position of the conveying tool. The opening of the reservoir is closed by means of the surface of the conveying tool in a second position of the conveying tool. The conveying tool can be moved from the first position into the second position via a thermo-sensitive switch that triggers the movement of the conveying tool. The disclosed device is suitable for metering pourable detergents, especially into the interior of washing or cleaning machines.

  • Patent number: 7469519
    Abstract: A process for producing a substance with a water-soluble packaging. The process comprises the following steps: a) a water-soluble material is deformed so as to embody a vessel; b) the vessel is filled with a filling material selected among the group comprising detergents, cosmetics, pharmaceuticals, body care products, auxiliary agricultural agents, adhesives, surface-treating agents, construction materials, dyes or food items; c) a water-soluble film web is applied to the filled container; d) the filled container and film web are sealed; and e) the sealed and filled container is finished. The inventive methods are characterized in that a negative pressure is generated in the filled container in the course of the process. In order to generate the negative pressure, the air located between the filling material and the water-soluble film web applied in step c) escapes at least in part through openings in the water-soluble film web applied in step c).

  • Patent number: 7446084
    Abstract: A method for the production of multi-phase detergents or cleaning agents, comprising the production of a water-soluble or water-dispersible container; the filling of said container with detergents or cleaning agents; application of a separating layer and filling of said container with other detergents or cleaning agents. The method is characterized in that a liquid separating agent is applied in order to form the separating layer, said agent solidifying in order to form the separating layer; the amount of packaging material used is reduced and the number of method steps is also reduced. the invention is further characterized by optimized use of space in the packaging body.
