<p>The system has a polymer material sheet that is elastically strained, and arranged perpendicularly towards a closing device. The closing device holds a sheet section, which receives an upper part of a container perpendicularly to the cited sheet, and is positioned to a certain height above a base line base of the sheet. A straightening of the sheet section is produced in radial and longitudinal direction, and cut sheet section near a narrow entrance of the container, which has an upper cylindrical zone attached to an outer surface of the container and lower zone cantilever. An independent claim is also included for an automatic closing equipment for narrow entrance of plastic or glass containers with different diameters, which are used in laboratories.</p> |
