DEVICE FOR PROTECTING AND SEALING THE OPENING OF A CONTAINER

1 . A plug for a flask or container, preferably made of one piece, comprising:

a. at least one passing channel, and

b. at least one structural flow regulator barrier,

wherein the passing channel comprises a preset configuration of the passing channel in which the configuration of its shape, geometry and materiality allows the passing of solid elements, and wherein the structural regulator barrier comprises at least a gate to regulate the passing and connection between the inside space and the outside space of the container in a unidirectional and/or bidirectional way, comprising a system for modulating the variation or the change of the volumetric spatial disposition of the structural flow regulator barrier, from an initial state to a second state, wherein the initial state blocks the passing channel and the second state allows the passing through the channel in a unidirectional and/or a bidirectional way.

2 . The plug of claim 1 , wherein the structural flow regulator barrier permanently blocks the channel unless the access is unlocked by the application of a perpendicular force over the gate surface exerted by a solid body, which causes a variation of spatial arrangement over the gate itself, allowing the mentioned solid body to pass through the passing channel.

3 . The plug of claim 1 , wherein the plug comprises a system to reset the initial volumetric spatial disposition of the gate position when the perpendicular force exerted by a solid body over the regulator barrier is no longer exerted.

4 . The plug of claim 1 , wherein the access is activated by the application of a force without breaking or causing any structural damage to the plug, so can be reused in a specific, variable or unlimited amount of times, and wherein the plug can be operated with the interaction of a range of solid objects.

5 . The plug of claim 4 , wherein the range of solid objects for interaction with the plug comprises: rounded, sharp, conical, flat and beveled objects, and any combination of them.

6 . The plug of claim 1 , wherein the plug is made of an elastomer material, wherein the elastomer material can be selected from at least one of the followings materials: is chosen from styrenics, olefinic, vulcanized thermoplastics, thermoplastic polyurethane, copolyesters, and copolyamides materials.

7 . The plug of claim 1 wherein the plug is operable to facilitate improvement of a time required to process at least one sample, relative a total time for sample processing without the plug.

8 . The plug of claim 1 , wherein the plug is operable to facilitate the improvement of the time required based on reduction of required use of at least one of: physical resources, human resources, material resources, economical resources, and any combination of them.

9 . A method for manufacturing the plug of claim 1 , wherein the method comprises at least one of the following stages:

a. pre-analysis, and

b. materialization,

wherein, the stage of pre-analysis comprises:

a1. observation for detection of possibility of intervention,

a2. problematization,

a3. solution strategy, and

a4. design proposals;

and wherein the stage of materialization comprises:

b1. mock-up,

b2. modeling for the physical and actual representation of the plug,

b3. digital prototype and template,

b4. manufacture of template and prototype,

b5. performance evaluation,

b6. testing prototype in real conditions, use and circumstances, and

b7. scaled production

10 . The method of claim 9 , wherein the step of manufacturing the template and prototype includes at least one of the following steps: 1) casting in combination with a rapid prototyping tool manufacturing process to obtain the positive (mold); 2) 3 D printing; 3) machining by roughing, for instance by a manual, computerized or mixed process; and 4) conforming by deposition of material.

11 . The method of claim 9 , wherein the step of manufacturing of template and prototype comprises a conformation molding process, comprising the elaboration of a mold for conforming at least one unit of a single-piece plug.

12 . The method of claim 11 , wherein the mold for conforming the plug comprises elaboration of multiple units of a single-piece plug, simultaneously or successively.

13 . The method of claim 9 , wherein the scaled production comprises at least one of the following steps: 1) casting, 2) injection molding, and 3) extrusion molding.

14 . The method of claim 9 , wherein the materialization stage comprises any format of computer-readable information directly, intentional or derived from digital prototyping or a manufacturing process involving the use of an automated machine, preferably at any time of the manufacture process.

15 . The method of claim 14 , wherein the computer-readable information comprises at least one of the following: numerical control programming language, parametric design approach, mesh design approach, and any combination of them.

16 . A system comprising a plug for a flask or container, wherein the plug is preferably made of one piece, and wherein the plug is produced by the method according to claim 7 .

17 . The system of claim 16 , further comprising flask or a container, wherein the plug is attached or connected to the flask or container.

18 . The system of claim 17 , wherein the container or flask comprises a sample.
