Abstract
Abstract A tamper indicating dispensing closure having a body member forming a dispensing passage at one end and an opening to receive the neck of a container at the other end in which the dispensing passage and opening in the neck are in communication with each other but are closed by a breakable foil seal element permanently attachable to both the closure and the container with which the closure is to be used. One end of the cylindrical body member of the closure is closed by a removable cap which gives access to the seal so that it can be ruptured to afford dispensing of the contents of the container.
