Method of manufacture of a cup comprising a clamp and in its upper part, and the cup from the other

摘要

It is proposed a method of manufacture of a cup which is intended to contain the liquid comprising a bottom of a circular shape and a flange (1) in the form of a sheet provided with two opposite sides (2), the method comprising a step consisting in winding thereon - same the sheet so as to produce a truncated cone, and to seal the side of the sidewall (1), called the "lower " (41) at the periphery of the base so as to give the cup a volume provided with an opening in the upper part, said aperture being delimited by two edges (421, 422) facing each other and located on the side of the so-called" upper " (42) of the sidewall (1). According to the invention, the method comprises a step of bonding the two edges (421, 422) of the opening of the clamp to put them into contact with the bend, the bonding takes place over a fraction only of the opening so as to leave an orifice opening allowing a liquid contained in the volume flow.
