  • Patent number: 4778069
    Abstract: The tamper indicating package includes a receptacle, such as a jar having a cover member threaded thereon. The mouth of the jar is sealed beneath the cover member with a seal member. The cover member has a depending flange with a slot that accommodates a tab indicating member joined to the seal member of formed integrally with the seal member. Rotation of the cover member from a predetermined closed limit position causes the slot in the cover member to interfere with the tab indicating member. The interference causes partial or complete severance of the tab indicating member from the seal member, providing a visible indication of previous tampering with the package.
