  • 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.

  • Publication number: 20070119124
    Abstract: A continuous process for producing water-soluble vessels, comprising the steps of: a) thermoforming a water-soluble film material to form receiving chambers in a shaping station; b) filling the formed receiving chambers with a filling selected from the group of the washing or cleaning compositions, cosmetics, pharmaceuticals, bodycare compositions, agrochemical assistants, adhesives, surface treatment compositions, building materials, dyes or foods in a filling station; and c) finishing the filled receiving chambers to the end product in at least one further finishing station. The receiving chambers formed in step a), in the course of the process, are transported by means of a support plate which has an orifice for each of the receiving chambers, so that the receiving chamber projects through the support plate freely through the orifice.
