The sachet (1) for a metered quantity of a fluid product comprises a first part (4a) and a second part (4b) in the form of sealed flexible layers having an annular attachment sector (8), a gripping region (13), and a sealed cavity (14), and, in a part of the gripping region (13), the layer portion of the first part (4a) and/or the second part (4b) is folded on itself from the edge (3) in a folded flap (18a, 8b), so as to form a thicker region (18) having a thickness at least twice the thickness of the layer portion of this part (4a, 4b), which makes up for at least part, or equalizes, or exceeds the overthickness in the region of the cavity (14), on account of the presence of the metered quantity of fluid product (P) located therein, so as to reduce or eliminate the risk of damage to the sachet (1) filled with the metered quantity of fluid product (P) when it is inserted into a magazine. |

1. Sachet (1) able and intended to contain a dose of fluid product (P), comprising a first part (4a) in the form of a fluidtight layer portion with a certain flexibility and a second part (4b) in the form of a fluidtight layer portion with a certain flexibility, the first part (4a) and the second part (4b) being arranged opposite so that the sachet (1) comprises:
an annular area (8) for mutual bonding that is fluidtight and that can be detached by a suitable opening action of the first part (4a) and of the second part (4b) in a reciprocal contact area of their two inner surfaces (9a, 9b), a gripping zone (13) that, toward the outside, is adjacent to the peripheral edge (3) of the sachet (1) and that, toward the inside, is adjacent to the bonding area (8), in which the first part (4a) and the second part (4b) are not mutually bonded so as to provide a gripping means of the tab type for the purpose of opening the sachet (1), a fluidtight cavity (14) bounded by the bonding area (8) and by the two areas that are not mutually bonded (15a, 15b) of the inner surfaces (9a, 9b) opposite the first part (4a) and the second part (4b) that it borders, able to receive the dose of fluid product (P) to be bagged,characterized by the fact that in at least one part of said gripping zone (13), the layer portion of at least one of the first and second parts (4a, 4b) is folded on itself at least from the peripheral edge (3) by a folded flap (18a, 18b), so as to form a raised surface region (18), with a thickness at least double the thickness of the layer portion of this part (4a, 4b), the sachet (1) thus comprising in the raised surface region (18) a raised thickness that compensates for, at least in part, or equalizes, or exceeds the raised thickness in the region of the cavity (14), due to the presence of the dose of fluid product (P) that is found there, so as to reduce or eliminate the risk of damaging the sachet (1) filled with the dose of fluid product (P) when it is inserted into a magazine. |
