<p>The flask has a tubular shaped body (2) and a neck (7) made of synthetic material, where the body is opened at its upper part. The neck has two parallel outer and inner skirts (10, 12) in its assembling zone, which cover an edge and an upper end of a peripheral wall (4) of the body. The wall delimits the upper part of the body, and the skirts delimit a groove (13) having a width lesser than or equal to the thickness of the wall, where the groove permits to embed the upper end of the body via a reduced thickness zone (5) of the body.</p> |
