摘要

Improvements introduced in the manufacture of pens with two-color charge, which are characterized by the fact that inside the body is provided a support with two holes for the seat of the springs that surround each bushing extender and guide of the same, and above this support retaining projections for the button of each load, whose buttons internally have longitudinal ribs that constitute cams which, in cooperation with steps provided in the interior, not only fix the position of the loads but in their travel they are susceptible of moving to the other pulsador so that it stops his retention and shoots to the position of retraction of the load.
