  • Patent number: 6334289
    Abstract: A tool designed to grip a collar projecting from the mouth of a plastic bottle, comprises a main body which is made of stainless steel and has three inserts made of hardened steel attached by means of silver brazing. The body has an internal edge in the form of an arc of a circle that is designed to surround part of the mouth of the bottle. Each insert carries a pointed projection which extends upwards. The projections, which define a horizontal support plane on which the collar is designed to rest, are particularly resistant to wear. The tool is used especially in bottling machines in order to allow the bottles to be gripped and handled.
