A lid-container assembly made of synthetic plastic material suitable for the transportation and storage of hazardous materials in conformity to the UN standard. The container includes a bottom and a substantially cylindrical or cone trunk side wall having an upper edge that bounds an access opening. The container is provided with a first external annular strip provided with a first circular rib and with at least one second circular rib for snap fitting of the lid. The lid includes a central part and a peripheral wall that conforms to the side wall of the container and further includes a second external annular strip that releasably engages the corresponding external annular strip of the container. The second external annular strip has an upper annular element that connects to the peripheral wall by an upturned U-shaped upper annular channel, and includes a lower annular element inserted into a lower annular channel in the form of an upwards pointing U, and an intermediate annular element for tear opening. The lower annular element of the second external strip includes a circular rib that engages a corresponding internal rib of the lower annular channel of the first external strip. The lid-container assembly further includes a first interference sealing zone between opposite surfaces of the side wall of the container and of the peripheral wall of the lid, a second contact sealing zone between the upper edge of the side wall of the container and the interior of the upper annular channel, and at least one third contact sealing zone between opposite engaging ribs of the first and second external annular strips.

A container system including a lid and a container is provided. A locking structure on the skirt of the lid is situated on a tear off portion and comprises a plurality of flexible tabs positionable in an upwardly biased locked position each independently engaging the container within an annular cut away on the container wall below a locking rib. If the lid is removed with tear off strip still engaged, the flexible tabs are biased downwardly and may break off, exposing tampering.

A package includes a container and a lid. The container may include a tamper evident feature, a child resistant feature, or both.

A tamper-evident container formed by thermoforming includes a tub having a bottom and a sidewall forming an interior volume. The container has a lid with an edge extending peripherally outward therefrom which is configured to mate with the tub edge to close the container. The lid edge has an inner portion and an outer portion with a perforated section therebetween. The perforated section extends continuously around the entire periphery of the lid, whereby the outer portion forms a tamper-evident seal removable from the inner portion for removing the lid from the tub.

Texture elements are distributed around the outer portion of the lid edge which are configured to provide a visual indication of the presence of the tamper-evident seal. The tub edge is disposed beneath the outer portion of the lid edge and extends peripherally outward so that a substantial part of the outer portion of the lid edge does not extend below the tub edge in a vertical direction of the container in an upright orientation. A tab extends from the outer portion of the lid edge and below the tub edge in the vertical direction of the container.

A safety closure for containers comprising a cover (3) and an internal element (4), the internal element being formed of a constraining portion (5) and a covering portion (6), the covering portion and the constraining portion being at least partially interconnected by means of at least a first preferential breakage zone (7B) which, when intact, joins them to each other, the constraining portion being provided with blocking means at the neck of a container with which the closure is intended to be associated and with first constraining means (10) which removably attach the cover, the internal element having sealing means (12) which, at least when the seal is intact, preserve the container content integrity.

The invention relates to a packaging comprising a plastic container (2), comprising side walls (20, 21, 22, 23) meeting in corners (24), an upper opening (25) and a bottom (26), as well as a detachable plastic lid configured to cover the upper opening of the container (2), and wherein said side walls (20, 21, 22, 23) of the container are divergent, together forming a truncated pyramid, configured so that said container can be stacked in an identical container. According to the invention, said container has projecting portions (29) extending from side walls at the upper opening (25) of the container, said projection portions (29) being external to the container, configured to guarantee a constant stacking pitch between the container (2) and said identical container, when said container is stacked in said identical container.
