Patents by Inventor Maren Hofferbert

Maren Hofferbert has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8470245
    Abstract: A device for reprocessing used plastic containers including a system for analyzing the degree of contamination of the plastic, a system for determining decontamination process parameters as a function of the degree of contamination thus detected, and a system for controlled decontamination of the plastic according to the decontamination process parameters thus determined. The system for determining decontamination process parameters provides determined decontamination process parameters to corresponding decontamination control elements that are automatically adjusted depending on the degree of contamination.
    Type: Grant
    Filed: August 30, 2012
    Date of Patent: June 25, 2013
    Assignee: Krones AG
    Inventors: Thomas Friedlaender, Maren Hofferbert, Hans-Jurgen Straubinger

  • Patent number: 8304457
    Abstract: A method and device for reprocessing used plastic containers, especially PET bottles, by analyzing the degree of contamination of the plastic, determining the decontamination process parameters as a function of the degree of contamination found in the analyzing step, and conducting a controlled decontamination of the plastic according to the decontamination process parameters thus determined. With this method and this device, it is thus possible to perform the decontamination process step in a controlled manner, yielding a more economical reprocessing method.

  • Patent number: 7981941
    Abstract: A method for reprocessing used PET bottles having the step of shredding the bottles to form plastic flakes, sorting the plastic flakes according to at least one criterion into at least two partial quantities, and performing an individual processing treatment including a decontamination treatment. The device permits performing the method whereby it is possible to separate the plastic flakes produced from the threaded part of a PET bottle, these flakes being more difficult to purify, from the lighter plastic flakes from the wall of the bottle, which have a thin wall and are easier to purify, and treating them further in separate reprocessing steps.
