ABSTRACT:
A container is provided that will minimize the possibility of tampering by unauthorized persons. The container is formed of a one-piece, thermoplastic material, preferable a transparent material, that would make any unauthorized entry in the container more readily visible to the buying public. The novel container is fabricated by a novel combined compression and blow molding process with a single opening that can be sealed after the container is filled. A closure cap is formed in the process as a portion of the unitary container, which cap can be readily separated from the container by the user for gaining access to the contents of the container, and thereafter used to seal the opening in the container between openings.
