FIELD: personal use articles.
SUBSTANCE: separation elements are position on the main surfaces of the products concerned. One exercised impact onto the products main surfaces ensuring their shift within the stack within a plane parallel to their main surfaces. During the plastic products manufacture one moulds, immediately on one main surface of each product to be further stacked several 3D separation elements, displacing the position of such element on each product relative to their position on the previous product serially towards one side by a preset angle equal to 10° - 90°, preferably - 15° - 40°.
EFFECT: invention allows to easily separate stacked ready 3D plastic products equipped with such separation elements so that to exclude such separation elements pressing-in.
