A polymer dispenser contains a polymer cover, a body with three cylindrical ribs on its outer surface, an insert and a ball. On the bottom of cover cap three concentric ribs are made. The outer surface of the cover foot is divided by a belt into two parts, the upper of which has the shape of a cylinder, and the lower one - the form of an inverted truncated cone. On the outer surface of the body the fourth cylindrical rib is made, which diameter is longer than the diameter of the other three ribs. All flexible cylindrical ribs of body have a rectangular shape with a slope of 3° to the edge of the ribs. The cover and body are made from polyethylene for foodstuffs, and the insert and ball - from polystyrene for foodstuffs. |
