    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

    Example 1

    [0020] Package with an opening covered by resealable label flap according to the first embodiment of the invention comprises a container body 1 which has a dispensing opening on its top surface and a dispensing opening 1a and a rigid reinforcing element 2 adhered to the top surface of the container body in the form of a sheet of PET foil, as well as a flexible top element 3 adhered to the reinforcing element 2, in the form of a sheet of BOPP film and a flap covering tightly the dispensing opening 1a. The container body 1 is in the form of a foil sleeve with tightly closed ends. The sides of the combination of the reinforcing element 2 with the top element 3 form a figure similar in form to a rectangle with significantly rounded corners. The label flap consists of fragments of the reinforcing element 2 and the top element 3 adhered to each other, separated by long cut lines 5 running towards the hinge line 5, which pass along the two sides of the combination of the reinforcing element 2 with the top element 3. Long cut lines 5 run on curves that are a combination of arches with different radii. The hinge line 4 is formed by a series of short cut lines passing between the end fragments of long cut lines 5 rounded to the outside of the base surface of the flap, towards the sides of the combination of the reinforcing element 2 with the top element 3. Roundings of the end fragments of long cut lines 5 have a radius R1 of 2.5 mm in length. Extreme cut lines 6 present in a R2 falling within 0.4 of the radius of the roundings R1 of end fragments of long cut lines 5, while opposite ends of extreme cut lines 6 have second roundings 8 defined by a radius length R3 falling within 0.2 of the length of radius of roundings R1 of end fragments of long cut lines 5. Located between the extreme cut lines 6, inner cut lines 9 are finished with third roundings 10 with a length of radius R4 falling within 0.2 of length of the radius of roundings R1 of end fragments of long cut lines 5. First roundings 7, second roundings 8 and third roundings 10 are directed to the outside of the base surface of the flap, towards the side of the combination of the reinforcing element 2 with the top element 3. Within the side of the combination of the reinforcing element 2 with the top element 3 located opposite the series of short cut lines, long cut lines 5 separate the pull ring 11. Within the surface of pull ring 11, the adhesive bonding the container body 1 with the reinforcing element 2 is deactivated. The design does not exclude an option of using such materials as OPS or PS or PP or PE for the reinforcing element 2.

    Example 2

    [0021] Package with an opening covered by resealable label flap according to the second embodiment of the invention comprises a container body 1 which has on its top surface a dispensing opening 1a and a rigid reinforcing element 2 in the form of a sheet of OPS foil adhered to the top surface of the container body and surrounding the dispensing opening 1a and the flap covering tightly the dispensing opening 1a. The container body 1 is in the form of a foil sleeve with tightly closed ends. The sides of reinforcing element 2 form an oval-like figure. The label flap is a fragment of the reinforcing element 2, separated by long cut lines 5 running towards the hinge line 5, which pass along the two sides of the reinforcing element 2. Long cut lines 5 run on curves that are a combination of arches with different radii. The hinge line 4 is formed by a series of short cut lines passing between the end fragments of long cut lines 5 rounded to the outside the base surface of the flap, towards the sides of the reinforcing element 2. Roundings of the end fragments of long cut lines 5 have a radius R1 of 2.5 mm in length. Extreme cut lines 6 present in a series of short cut lines, from the side of long cut lines 5, have first roundings 7 with radius length R2 falling within 0.4 of the length of the radius of roundings R1 of end fragments of long cut lines 5, while opposite ends of extreme cut lines 6 have second roundings 8 with a radius length R3 falling within 0.2 of the length of radius of roundings R1 of end fragments of long cut lines 5. Inner cut lines 9 located between the extreme cut lines 6 are finished with third roundings 10 with radius length R4 falling within 0.2 of the length of the radius of roundings R1 of end fragments of long cut lines 5. First roundings 7, second roundings 8 and third roundings 10 are directed to the outside of the base surface of the flap, towards the side of the reinforcing element 2. Within the side of reinforcing element 2 located opposite the series of short cut lines, long cut lines 5 separate the pull ring 11.
