ABSTRACT:
A safety device for providing clues that a capped container has been opened a first time. Frictional male female joints releasably interconnect the cap to the container. This safety device is of the tear-off type, wherein by peeling one peripheral portion of the annular wall portion of the container cap, the cap can be released from the container mouth, while at least some frictional joints remain between the cap to enable continuous efficient interconnection capability regardless of the number of cap opening/closure cycles. The peeled cap strip is then disposed of--it is not reusable. Thus, its absence about cap signals that someone has already opened the cap to access the content of the container.
