Patents by Inventor Geoffrey B. May

Geoffrey B. May 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).

  • Filmic packaging material and a tear adherent thereto
    Patent number: 5595803
    Abstract: A teartape for packaging materials, and particularly such materials based on polyolefin films, includes a base film coated with a pressure sensitive adhesive composition. The teartape is affixed to the packaging material by the adhesive composition. This avoids the problem of distortion which can occur when affixing conventional teartapes to such packaging materials by means of hot melt wax compositions. The teartape is applied to moving packaging material by controlling the speed of the teartape in accordance with the speed of the packaging material so as to reduce tension imbalance. The speed of the teartape may be controlled in dependence upon the tension in the teartape. This can be achieved by supplying the teartape from a dispenser having a brake means (4,5) and a drive means (10,11,12) for regulating the speed of the teartape in dependence on the tension in the teartape.
    Type: Grant
    Filed: March 4, 1994
    Date of Patent: January 21, 1997
    Assignee: P. P. Payne Limited
