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. |

1. A sealing mechanism of crystal polystyrene for packaging containers, comprising:
a first pin (2); a second pin (3) configured to engage in a seat present on an edge of a container; and a tab (4) configured to fit into a space between the first and second pins, wherein: the first pin (2) is composed of a plate (20) wherein, at one end, there is an edge (21), positioned orthogonal to the plate and envisaged to rest on an inner edge of the container and, at the other end, there is at least one tooth (22), with a wedge-shaped configuration, positioned on the same side as the edge (21) and envisaged to engage with the container, the second pin (3) is composed of a plate (30) wherein, at one end, there is at least one tooth (32) with a wedge-shaped configuration, envisaged to engage with the container and, at about one third of the plate (30), on the free end side, there is a lug (33), positioned transversely and arranged to rest on the outer edge of the container, and the tab (4) consists of a strip (40) which features, at one end, rounded corners (41) for smooth entry between the pins (2 and 3) and, at the other end, a handgrip (42), positioned orthogonally to the strip, envisaged to rest on a container lid and equipped, at the top, with a small loop (45) and a slot (46), envisaged to accommodate a user's finger when the container has to be opened. |
