FIELD: package.
SUBSTANCE: invention concerns sealed container with pull-on cover. Container includes case with cylindrical gorge and cylindrical cover, upper surface of which is sealing the gorge part. The case structure restrains gorge deformation by restraining case part deformation inwards when a strain is applied to the case part. The case is made of polyethylene terephthalate. Gorge part features unbroken annular ledge running along the perimetre of cylindrical outer wall, and the cover has unbroken annular groove running along its internal wall for pulling on the annular ledge. Container is made of amorphous polyethylene terephthalate with 1.320-1.340 g/cm3 density and width within 80 mcm to 390 mcm.
EFFECT: transparent cost-effective container with good recycling capacity, requiring no chemical modifications, resistant to cracking, preventing leakage.
