The top is made of thermoplastic polymer and is connected to the upper end of the main housing. The opening of the opening device is made integrally with the top and comprises a plurality of stages and the level changes on the front side and rear side of the opening. The level changes on the front side and the level changes on the rear side are formed along the edges of the level changes at front and rear with overlapping, at that the lengths of the overlap of the edges of the level changes are less than the thickness of the steps. The level changes are easily breakable parts. The steps have thickness of 190-650% in relation to the length of the overlap of the edges, and the overlap of the edge is 0.09-0.11 millimetres in length.
EFFECT: opening device for drinking straws provides easy opening of the container opening.
