<p>A tool (1), designed to grip a collar (2) projecting from the mouth (3) of a plastic bottle, comprises a main body (4) which is made of stainless steel and has three inserts (7) made of hardened steel attached by means of silver brazing. The body (4) has an internal edge (5) in the form of an arc of a circle that is designed to surround part of the mouth (3) of the bottle. Each insert (7) carries a pointed projection (6) which extends upwards. The projections (6), which define a horizontal support plane on which the collar (2) is designed to rest, are particularly resistent to wear. The tool (1) is used especially in bottling machines in order to allow the bottles to be gripped and handled.</p> |
