Abstract
YA tamper indicating dispensing closure for attachment to an originally filled container to indicate prior opening or tampering. The closure has a base cap with a dispensing orifice therethrough and an upstanding retention sleeve. A lid is hinged to the base cap and has a tamper indicating disk attached to it by a pin extending through the lid. In its originally packaged condition, the pin extends into the retention sleeve with the lid closed. A frangible area on the disk around the pin breaks upon initial opening providing evidence of tampering or prior opening.

A tamper indicating dispensing closure for attachment to a container comprising, in combination:
- a base cap having a top with a dispensing orifice therethrough and with an upwardly projecting retention sleeve thereon and a depending annular skirt having means for attachment to a container;
- a lid attached to said base cap by a hinge for movement between an open dispensing position and a closed position covering said dispensing orifice;
- and a tamper indicating disk having a pin projecting therefrom extending through an aperture in said lid and into engagement with said cap retention sleeve when said closure is initially attached to a filled container with said lid in the closed position, said disk being a member separate from the lid, said disk having a frangible area circumscribing said pin;
- whereby when said lid is initially opened, the pin will be retained by said sleeve breaking away from said disk at said frangible area thereby indicating tampering or initial opening.
