A sachet has a body, the inner space of which is notably delimited by two sheets forming its main walls, and which includes complementary closing profiles respectively attached on these sheets as well as a cursor for actuating the profiles upon closing and opening, which comprises two longitudinal flanks connected by a base, as well as a longitudinal sole which extends from the base between the flanks, in order to delimit two opening/closing channels of the profiles. The cursor includes, longitudinally, in the extension of the base, a jutting-out element which extends beyond the flanks. The jutting-out element is positioned on the side of the cursor which corresponds to a closing direction of the profiles.
