Abstract

Abstract A plastic container is produced as an integral unit comprising a container body, and a cap portion connected thereto. The cap portion has an opening in the top through which the container is filled. A separately produced lid means is adapted to cover and seal the opening in the cap. The cap is initially torn from its position integral with the container body, then placed upon the container as a closure member. A tell-tale flag may be affixed to the cap and body to indicate tampering. When the cap is initially torn from the container body the tell-tale flag is detached. A sealing disc may be provided on an upper portion of the cap. The container body is also provided with vertical and horizontal grooves to accommodate a key portion affixed to the cap to provide a child-resistant feature.
