Abstract
The invention relates to pharmaceutical closures for containers made of flexible polyolefinic materials which are suitable to be filled with parentally administrable fluids prior to their sealing and sterilization. The polyolefinic closures have an excellent resealing capacity after being penetrated by a piercing device for establishing fluid communication with the container, even after multiple entries into the container.
