Abstract:
The neck closure has a wedge-shaped hollow neck with lips formed on the front wedge edge by converging wedge surfaces, the lips being connected to form a one-piece closed lip by a thin section, and having a cover cap that can be placed over the neck. When the cover cap is in place, the front region of the wedge-shaped neck is held in a position that has been rotated through at least 5 DEG in a clockwise direction, viewed from above, in relation to its normal unstressed position, as a result of the inner moulding of the cover cap. When the cover cap is rotated anti-clockwise, from this closed position, force is only applied to the front wedge edge region of the neck by pressure surfaces projecting from the inner face of the cover cap at diametrically opposed points on said front wedge edge region.
