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.

Claims

1. Bag-sealing device characterized by taking the form of a Fermat'"'"'s spiral (FIG. 1), having an appendage curved towards the center of the spiral on the tip of the inside branch of the open end of the spiral (1) and including on the tip of the outside branch of the open end of the spiral (2) a first hook (3) and a second hook (4) which locks together with the previous one and is located on the outside surface of the said branch on the closed part of the spiral.

2. Bag-sealing device as recited in claim 1, characterized by being made of a material which has the mechanical property of changing shape in an elastic manner (resilience).

3. Bag-sealing device as recited in claim 1 in which, for the purpose of adjusting the pressure exerted on the bag positioned inside it, the form described is modified by the following procedure:

the more the length of the outside branch of the open end of the spiral (2) is reduced the greater the pressure on the bag. When the aforementioned length is increased the pressure on the bag is reduced.

5. Bag-sealing device as recited in claim 1, characterized by the resulting shape of the device when the hooks are locked together providing a smooth form which permits the positioning of tape over the same, for the purpose of making the manipulation of the bag more difficult and protecting its content.

4. Bag-sealing device in which the act of closing (FIG. 2) consists of both hooks (1) (2) locking together through the action of a pressure exerted on the spiral after the bag has been introduced into the interior of the same (3) and the act of opening the bag also consists of the action of pressing on the spiral to unlock the hooks.
