摘要

The aperture is a hole cut on the cover or the lateral wall of the box. A cover slip of the same form but bigger can rotate around an axis on the interior face of the wall and has a projection (8) on the exterior face. The aperture is covered exteriorly by an adhesive sheet (11) and internally by another adhesive sheet (14) prior to the first use. The user removes the exterior sheet then rotates the cover slip by pushing the projection with his nail. The cover is closed by rotation in reverse direction.
