ABSTRACT:
A method is provided for reducing particle formation during manufacture of shell caps for containers such as pharmaceutical containers. The method entails providing a solid polymeric coating on substantially all surfaces of the shell caps to form coated shell caps before permitting the coated shell caps to contact each other or other objects. A pharmaceutical container which employs the shell caps also is provided. The container comprises a vial for storing medicinal compositions therein and a shell cap for sealing the vial. The shell cap includes a hollow metallic preform and a solid polymeric coating which substantially completely encapsulates the preform.
