  • Easy-open, individual unit dispensing package
    Patent number: 4696402
    Abstract: A novel package having a perforated tear strip with openings capable of firmly binding at least one side of individual product units and a means for enclosing and securing the other side of the individual product units in order to prevent the product units from engaging in motion sufficient to dislodge themselves. As the tear strip is torn back, product units are released individually and the undispensed product units remain securely in place. Such novel packaging is easily opened, is space efficient and can be made visually appealing.
