A mechanical elastic device is provided and designed for the closing and opening of bags manufactured from flexible material an indefinite number of times via the pressure exerted by this device (through taking the form of a Fermat's spiral) on the area of contact with the bag inserted into the same. The elastic device is operated by positioning the part of the bag to be fastened inside an interior space of the spiral and then aligning two hooks provided on the surfaces of the elastic device until they lock together, thus producing a reduction in the interior space of the spiral and, as a result, this part of the bag is tightened to remain hermetically sealed. The elastic device is opened by simply releasing the joined hooks with an external force, so the spiral will then return to its relaxed position and the bag can be extracted from the elastic device.
A bag-sealing device comprising a continuous band shaped in the form of a Fermat's spiral having a closed end, an open end and an interior space (7) defined between said closed end and said open end inside inner surfaces of the spiral, wherein said closed end includes a first hook (4) protruding from an outer surface of the spiral near a tip of said closed end and said open end includes a first branch (1) with a curved appendage (1a) and a second branch (2) with a second hook (3) protruding from said inner surface of the spiral, said first branch (1) and said second branch (2) being separated to define an entrance (5) to said interior space (7) so that said first hook (4) and said second hook (3) are configured to latch together when the tip of said closed end is inserted through said entrance (5).
