ABSTRACT:
A tamper indicating container and closure combination in which the container has configurations about the neck thereof registering with configurations on a separate portion of a closure engageable therewith, which separate portion is separated from the closure when the closure is removed from the container. A sealing disc is positioned in the closure by limited frictional engagement therewith so that when the closure is removed from the container, the separable portion of the closure remains on the container as an indicator and the sealing disc remains in sealing relation on the container and must be wholly or partially removed by a tab thereon to gain access to the contents of the container whereby the sealing disc and tab forms a second indicator.
