  • Patent number: 4428747
    Abstract: A blister package, particularly for sanitary tampons (3) for women hygiene, is comprised of a pressed foil (1) forming a deep hollow and of a cover foil, and comprises a deposit (6) for an additive, preferably a lubricant. The deposit (6) is arranged in a main trough (19) intended to receive the sanitary tampon (3). The deposit (6) may be shaped as a cup (5) of the pressed foil (1) and opened in the hollow of the pressed foil (1) or be covered or separated from the main trough (19). The deposit (6) may be relieved through the opening of the blister package and brought in contact with the end (3a) and the pad (3), but the deposit may also be pressed by means of the finger applied pressure in the direction of the end (3a) of the pad (3) to coat it before the opening of the blister package and the use of the pad (3). The additive will therefore be applied immediately before using the sanitary tampon, so that all of the amount of additive available achieve its purpose.
