Abstract
A tamper indicating dispensing closure for containers in which a cylindrical cap has a passage for dispensing the contents of the container and the passage is closed by a member requiring movement relative to the remainder of the cap. The entire top of the cap is covered by a tamper indicating element which is permanently attached to the remainder of the cap so that the element must be removed in order to perform the opening operations of the closure and such removal results either in the destruction of the element or in the means fixing it to the cap to visually indicate that the closure has been opened or placed in a condition for opening.
