摘要

Improvements in the mechanisms of closing governed by spring, according to which they are organized on a box consisting of a sheet on whose surface two extreme openings are produced, so that the emptying material is raised forming separate wells to support the corresponding branches of two laminar springs, whose springs are housed in the hollow space determined by the box and a movable plate that is mounted on it.
