<p>A projecting structure (30, 110, 530) is integrally formed with a neck (32, 532) of a bottle (10) or preform (20), or with a closure (100, 200, 300). The projecting structure comprises a ring-like element (34, 112, 534) that extends around the neck or closure body (102) and is supported therefrom by a plurality of discrete web formations (40, 120, 540). Adjacent web formations define in the projecting structure an optionally elongate aperture (42, 116, 542) therebetween.</p> |
