Abstract
The invention relates to a mold for the production by means of blowing or blow-drawing of thermoplastic containers which are equipped with an integral handle. According to the invention, two mold halves are provided with two respective inserts which can move transversely to the contact faces. Each of the aforementioned inserts comprises two telescopic pistons, namely: a main piston having a front thrust face, and a secondary piston which is housed in the main piston and which has a curvilinear front weld face. The secondary pistons are moved after the main pistons have applied two wall zones of the container body against one another.
