Abstract
Abstract In a hollow plastic, integrally formed, blow molded article of manufacture, wherein a pair of normally open-mouthed containers are connected in a mouth-to-mouth relationship by a waist ring. The waist ring and the container mouths both have annular inwardly extending webs which connect to form annular grooves between the waist ring and mouths which provide, upon separating the containers by cutting at the grooves, finished containers requiring no further finishing operations.
