<p>A closure (1) for a bottle is described, which can be partially inserted into a mouth (13) of the same by means of thrust force along a longitudinal axis (A-A') thereof, the closure comprising an annular region (2) transversal to the axis and being such as to identify first (3) and second (4) portions being counterposed relative to the to annular region. The annular region (2 is provided with a groove (5) Being joined to said first and second portions. The presence of the groove reduces the deformations experienced by the closure when the same is applied to the bottle, thereby improving the tightness of the seal.</p> |
