This cap (1) has a tubular skirt (12) to fit around the outside of the neck (2) of the container. The skirt has internal means for clipping it onto the neck which are designed to secure the cap removably to the neck by forming a tight fit with an edge of the neck. The skirt also has an external tab (14) for manually unclipping the cap, the tab extending out from the skirt and occupying only a portion of the periphery of the skirt. In order that the cap can be placed around the neck accurately and efficiently by ordinary bottling heads, the skirt also has an external collar (16) which extends outwards from the skirt and occupies a portion of the periphery separate from the portion associated with the tab, being separated from it at either end along the periphery of the skirt, with at least one part, occupying more than 180° around the central axis (X-X) of the skirt possessing, in a cross section at right angles to this axis, a circular external profile concentric with the axis and having a radius approximately equal to the maximum radial distance between the axis and the external profile of the tab. |
