Method for locking together two containers especially plastic bottles with interlocking grips equally spaced from a central pivot connection for a twist and lock action

摘要

A method for connecting together two containers, e.g. plastic bottles, has interlocking socket and plug grips (8, 9) about halfway up the outsides of the containers and with other interlocking grips (14, 15) equally spaced from the central pivot grip to facilitate a simple twist and lock action to link the containers. The containers are separated by a reverse twist action. The central pivot connection includes conical self aligning profiles and the outer grips include clip fitting profiles.
