Patent number: 10004255Abstract: A tobacco product is formed by rolling a sheet of material supplied by a roll or rolls (e.g. moistened tobacco leaves) and/or homogenized sheet tobacco about a slit mandrel to form a shaped tube. The shaped tube is then packaged for shipment to an end user or consumer. The shaped tube remains in the rolled, shaped tube form inside the package. After the shaped tube is removed from the package, a consumer can fill the tube with crushed tobacco leaves or other tobacco filler material of a favorite blend, thereby eliminating some steps in the making of a “roll-your-own” tobacco product. A liquid can be added to the sheet or to the finished tube to moisturize same. The liquid can include flavoring. The tubes are unfilled when packaged and sent to a consumer/end user in tube form so that they have a “memory” that helps hold a tubular cigar shape after they are filled with selected tobacco fill material.Type: GrantFiled: July 2, 2017Date of Patent: June 26, 2018Assignee: Blunt Wrap U.S.A, Inc.Inventor: Daniel S.

Patent number: 9988304Abstract: Certain example embodiments relate to an improved method of strengthening glass substrates (e.g., soda lime silica glass substrates). In certain examples, a glass substrate may be chemically strengthened by creating an electric field within the glass. In certain cases, the chemical tempering may be performed by surrounding the substrate by a plasma including certain ions, such as Li+, K+, Mg2+, and/or the like. In some cases, these ions may be forced into the glass substrate due to the half-cycles of the electric field generated by the electrodes that formed the plasma. This may advantageously chemically strengthen a glass substrate on a substantially reduced time scale. In other example embodiments, an electric field may be set in a float bath such that sodium ions are driven from the molten glass ribbon into the tin bath, which may advantageously result in a stronger glass substrate with reduced sodium content.Type: GrantFiled: September 2, 2011Date of Patent: June 5, 2018Assignee: Guardian Glass, LLCInventors: Vijayen S.
