Stopper for closing neck of e.g. bottle, containing three, four or five gallons of water in distribution fountain, has skirt part delimiting radial support surface and axial support surface projected from support surface toward outside

摘要

The stopper (1) has a cap (10) to close a neck (3), and a tubular skirt (20) fixed at the neck and centered on a central longitudinal axis (X2) by being arranged around the neck when the stopper is in closing configuration. The skirt has a first part connecting rest of the skirt to the cap, a second part connecting a free end of the skirt to the rest of the skirt and a third part connecting the skirt parts. The third part delimits an outer radial support surface complementary to interior surface of the end and an outer axial support surface projected from the support surface toward outside. Independent claims are also included for the following: (1) a group of stoppers (2) a stopper and a plate assembly.
