Abstract
It is possible to provide a dispensing closure which is tamper evident by using a relatively flexible strap connecting the movable end of a spout as conventionally used in such a closure with a cap or cap body employed in such a closure. The use of such a strap makes it possible to mold the spout and the cap as a unitary article. The assembly of a dispensing closure from such an article avoids the possible problem of a "wrong" spout being assembled with a specific cap or cap body. The strap employed should not extend from the cap so as to interfere with the use of conventional capping apparatus. The strap used can be shaped and dimensioned to facilitate location of the spout during the assembly of the spout on the cap or cap body and, if desired, as a cover for the passage in the spout when the spout is assembled in an operative position.
