Abstract
Mechanical elastic device designed for the closing and opening of bags manufactured from flexible material an indefinite number of times via the pressure exerted by this piece (through taking the form of a Fermat'"'"'s spiral) on the area of contact with the bag inserted into the same.
Its method of operation consists of positioning the part of the bag we wish to fasten inside the closed area of the spiral and then aligning the two hooks which the piece has on its surface until they lock together, this produces a reduction in the interior space of the spiral and, as a result, this part of the bag is tightened to remain hermetically sealed.
To open it one simply has to release the joined hooks with an external force, the spiral will then return to its relaxed position and we can extract the bag from the device.
