A sealing mechanism for packaging containers offers the end recipient a way of testing and guaranteeing that the container has not been tampered with or opened during transport operations, and that it has reached its destination in the same condition as when it left. The sealing mechanism for packaging containers of the “low-coefficient” type includes a first and second pin for engaging with a relative seat present on the edge of the container, and a tab designed to fit into the space between the pins. The mechanism for packaging containers of the “high-coefficient” type features, a plate as a first component envisaged to fit into a relative seat present in the container, a second component including an opening block and a fitting designed to engage with the lid of the container, and a pin envisaged to engage with the first component and the second component, securing the entire mechanism.

The sealing mechanism for packaging containers according to claim 1, wherein the plate (20) of the first pin (2) has at least one rib (23) positioned transversally to the plate. 3. The sealing mechanism for packaging containers according to claim 1, wherein, in the tab (4), between the handgrip (42) and the strip (40), there is a rupture element composed of a central pin (43) and at least two lateral pins (44), featuring slightly tapered outer edges. 4. The sealing mechanism for packaging containers according to claim 1, wherein said tab (4) has at least one rib (47), positioned transversely to the strip, about a quarter of the way along the length on the side with the rounded corners (41), and envisaged to abut with the rib (23) on the first pin (2), the tab (4) being able to feature the rib (47) on one side or on both. 5. The sealing mechanism for packaging containers according to claim 1, wherein all the surfaces of the first pin (2), the second pin (3), and the tab (4) are rough to create friction when they are in contact with the walls of the container and also reciprocally. 6. The sealing mechanism for packaging containers according to claim 1, wherein the mechanism is configured for use with containers having thin walls and are defined as ‘low-coefficient’. 7. The sealing mechanism for packaging containers according to claim 1, further comprising: a first component (5), arranged to fit into a suitable seat present in a container; anda second component (6), arranged to engage with the container lid, and a third component (7), envisaged to engage with the first and second components, locking the entire mechanism,wherein:the first component (5) is composed of a plate (50) which has an orthogonal edge (51) at the rear, on one side, while on the side opposite an H-shaped protuberance (52) and in each space created within the H-shaped protuberance, there is a peg (53), the rear side of the plate (50) being arranged to abut with the wall of the container, making both the edge (51) and the pegs (53), as well as the H-shaped protuberance (52), enter the container, while the plate (50) features, at the front thereof, a recess (51) endowed with a rib (51a),the second component (6) is composed of two elements: an opening block (60) and a fitting (65) wherein the opening block (60) is composed of a sheet (61) surrounded by a peripheral edge which protrudes slightly on both faces (62) and in each corner there is a pin (63) envisaged to penetrate the polystyrene of the container when the block is positioned in the seat thereof, the sheet (61) featuring, at the centre thereof, a button (64) endowed with a central groove (64a) positioned along the diagonal, which is used when the mechanism and container are open, and on the edge thereof, positioned diametrically opposite the groove, a pair of small lugs (64b), having the function of guarantee seals, and including, on the inner side, a relief (64c) with an upper edge shaped so as to couple, in an obligatory fashion, with a corresponding profile (65d) present in the fitting (65) and, also on the inner side, the button being endowed with an element (64d) which projects out from the button, in a perpendicular fashion, and is provided with a tip (64e), at the free end, and a slot (64f), just below the tip, envisaged to accommodate and engage with the third component (7), and the fitting (65) consists of a ring (65a) which features a shaped edge (65c), positioned orthogonal to the ring and provided with a couple of loops (65e) positioned between them, diametrically opposed and located in correspondence with the small lugs (64b) of the button (64), andthe third component (7) consists of a pin which features, at one end, a pair of tips (70) positioned in a reciprocally parallel fashion and each provided with an enlargement (71) towards the outside, the tips being designed to be inserted in the slot (64e), while the enlargements (71) are envisaged to engage the third component (7) in an unmovable fashion with the second component (6), the third component (7) comprising, on the side opposite the tips (70), an opening (73) containing a tab (74), which is slightly splayed outwards and envisaged to enter the recess (51) in the first component (5) and engage with the rib (51a), which firmly locks the tab when the container is sealed with the lid. 8.
