| 20130320076 | SECURE CASE - The security packaging device according to the invention consists of a known cut-resistant textile structure having integrated conductive thread layers which, in the event of mechanical loading, trigger an alarm signal. When cut-resistant knitted spacer fabrics are used, the inner surfaces of the top side and the entire underside or the inner surfaces thereof are conductive. Additional weft insertion threads, which are parallel to the spacer threads, are arranged as spacers between the top side and underside, in order to prevent any unintentional contact if pressure is applied. | 12-05-2013 |

| 20160083142 | PACKING LIST ENVELOPE WITH PULL TAB AND METHOD FOR FORMING THE ENVELOPE - An envelope including: a front sheet and a back sheet coextensive and overlapping the front sheet; a pull tab formed in the front sheet between lines of weakness in the front sheet, wherein the pull tab includes a front tongue having an edge defined by a line of weakness in the front sheet and extending between the lines of weakness; heat seals between the front and back sheet proximate to the perimeter of the envelope; a release sheet on adhesive coated side of the front sheet, wherein the adhesive coated side is opposite to a side of the back sheet facing the front sheet, and a slit through the release sheet and the back sheet along a line parallel to an edge of the envelope. | 03-24-2016 |
| 229310000 | Gripped portion of tearing element secured to envelope exterior | 1 |
| 20110101082 | MAILING ENVELOPE - A mailing envelope comprising a sleeve with an opening at open end and a closed end, a closure associated with the opening at the open end, an envelope fold line intermediate the open end and the closed end when the envelope is in a flat configuration and one or more adhesive areas for at least partially maintaining the envelope in a folded configuration. Also, a method for packaging one or more sheets and/or components in the envelope. | 05-05-2011 |
| 229311000 | Cord, string, wire, or thread | 2 |
| 20080223914 | Frangible Envelope Portion with Tear Line - Disclosed is to an easy-open envelope having a tear-line located within a length of the envelope's seam fastened to frangible portions of the envelope created by strategically placed perforations creating an envelope mailer with an integral opener that eliminates the need for using a knife or letter opener potentially damaging the envelope contents or using a finger which leaves the envelope ragged. | 09-18-2008 |
| 20110168770 | TEAR-PROPAGATION RESISTANT ENVELOPE - An envelope can include a first wall with a first edge, a second wall with a second edge connected to the first edge along a connected portion configured for providing a side of the envelope, the first and second edges respectively including first and second separate portions that are separate from each other, the separate portions extending from the connected portions at a transition location and a reinforcing member associated with the connected portion adjacent the transition location for reinforcing the connected portion adjacent the transition location. An apparatus for making an envelope is also disclosed. | 07-14-2011 |
| 229313000 | Line of weakness | 6 |
| 20120031959 | APPARATUS FOR FASTENING AND/OR SEPARATING CONTAINER PORTIONS - An apparatus for at least partially separating at least two container portions includes first and second container portions. At least one tear line extends at least partially between the first and second portions and at least partially defines the first portion. The first portion is at least partially separable from the second portion along the tear line(s). At least one releasable adhesive spot at least partially holds the first portion down prior to the at least partial separation of the first portion from the second portion. | 02-09-2012 |
| 20140284377 | DUAL DIRECTIONAL OPENING TYPE MAIL ENVELOPE - A dual directional opening type mail envelope has opening start section with cutting part and cutting lines marked with arrows in the center that can be cut from both sides and a cutting part that had been partly cut beforehand. Dual directional opening type mail envelope includes an opening start section with a cutting part and cutting lines marked with arrows that open when the thumb and index finger of the left hand flips the cutting part back where first and second cutting line are opened cleanly and rapidly and as thumb nail on the right hand is inserted into the gap to move left and right as cutting lines are comprises of arrows placed with distance which ensures an easy and quick opening of the envelope will be opened rapidly as a flying arrow without leaving any residue. | 09-25-2014 |
| 229316000 | Line of weakness extends along or adjacent envelope side edge | 4 |

| 20160145005 | POSTAL ENVELOPE DESIGNED TO CONTAIN ONE OR MORE OBJECTS WITH TWO-DIMENSIONAL DEVELOPMENT, IN PARTICULAR CARDS, CDS, DVDS, OR CREDIT CARDS - A postal envelope for containing one or more objects with two-dimensional development is formed starting from a sheet, with two flaps that fold on the sheet like a book. The first flap forms a pocket designed to receive the two-dimensional object. The second flap comes to cover the remaining uncovered part of the sheet. The first flap is glued to the sheet at its three free sides so as to prevent the object from coming out. To take the two-dimensional object out of the envelope the first flap has, at a short distance from its area of the long side glued on the sheet, a tear-away strip, the length of which accommodates the two-dimensional object contained in the pocket and which is shaped so that, by being removed, it will define a slit through which the two-dimensional object contained in the envelope can be easily taken out. | 05-26-2016 |
