Abstract
A tape formed of a polymeric material and having a thickness and stiffness suitable as a cutting edge on a dispensing carton for convolutely wound foil, film or paper, the tape includes a coating of adhesive and is applied at a laminating station in the carton manufacturing process and is generally cut with the forming of the carton blanks, and the cut in the tape may be formed with a serrated edge.
Claims20
An adhesive tape for use as a cutter bar for dispensing cartons, said adhesive tape comprising:
- a) a backing of between about 2 mils (0.05 mm) to about 7 mils (0.18 mm) in thickness comprised of a polymeric film material selected from the group consisting of polyester, polypropylene and polyethylene, and
- b) said backing having opposite edges, and opposite sides, one of said sides being coated with an adhesive having high adhesion to a fiber board for forming dispensing cartons.
A method of forming a cutting edge on a dispensing carton for film, foil or paper comprising the steps of:
- a) forming a tape having a polymeric backing coated with an adhesive on one side,
- b) supplying a roll of said tape to the application station in a box forming machine,
- c) applying the tape to the carton board in the box forming machine and laminating the same, and
- d) cutting the carton board into carton blanks and the tape lengthwise to form a cutting edge on each blank.
A dispensing carton for use in dispensing foil, paper and film comprising:
- a) a front panel, a bottom panel, a rear panel, each having panels at opposite ends to form the ends of the carton;
- b) a lid connected to the rear panel and a flange joined to the lid to overlap said front panel;
- and
- c) a cutting edge formed on one of said front panel and said flange joined to said lid for severing lengths of material dispensed from said carton, said cutting edge formed of a polymeric material selected from the group comprising polyester, polypropylene and polyethylene and having a thickness between 2 mils (0.05 mm) and 7 mils (0.18 mm) and adhered to said one of said panel and flange by adhesive.
