FIELD: transportation, packing. ^ SUBSTANCE: invention relates to packages with an indicator of opening. Package produced from base comprises the first and second sections of base surface, which are attached to each other, and the third section of surface adjoining to the first section of surface and at least partially coated. Adhesion between coating and base is realised with the force of adhesion, having the first value. In package there is a fourth section of surface, adjoining to the second section of surface and only partially coated with adhesive. At the same time adhesion is realised between adhesive and base with force having the second value, and adhesion between adhesive and coating - with the force having the third value. The second and third value is more than the first value of adhesion force. Package has painting of coating, which differs from painting of the third section of surface, fourth section of surface or adhesive. Coating and adhesive are at least partially in contact with each other. ^ EFFECT: separation of the fourth section of surface from the third section of surface provides for at least partial removal of coating from the third section of surface and therefore, visual indication of the package opening is provided. ^ 38 cl, 9 dwg |
