Packaging comprising, on the one hand, a plastic container having lateral walls, a top opening and a bottom, and, on the other hand, a removable plastic lid that is configured to cover the top opening in the container, wherein the container is provided, at its top opening, with a first engagement portion bearing and outward-directed rim that extends around the periphery, the lid being provided, on its peripheral part, with a second engagement portion that is folded downward and has an inward-directed rim which is able to latch underneath the outward-directed rim of the container, and wherein the second engagement portion of the lid has a skirt with foldable skirt section, the free end of which catches in a reception portion of the container.

A container package includes a container and a lock-on closure that couples to the container. The container includes an annular sidewall. The closure includes a channel portion having an inner, an outer, and a top wall that define a channel. The inner wall includes a primary seal having sealing ridges formed thereon. The closure further includes a single, flexible sealing wiper appendage extending away from the top wall. When the sidewall of the container is outside of the channel, the appendage is in a first position in which it extends downwardly and is angled inwardly so a terminal end of the appendage is freely suspended within the channel. When the sidewall of the container is in the channel, the appendage is in a second position in which the terminal end is closer to the inner wall than in the first position and the appendage contacts the top rim.

A pail includes a container and a lid. The container includes a base, a container sidewall extending upwardly from the base to an upper rim, and a sealing rib extending from the container sidewall adjacent to the upper rim. The lid includes a channel for receiving the upper rim of the container, the channel includes a channel base, a plurality of protuberances arranged spaced apart on an inner surface of the channel base and extending downwardly therefrom, a first channel sidewall, and a sealing shoulder that projects inwardly from the first channel sidewall. When the upper rim of the container is received by the channel of the lid, the protuberances abut the upper rim and the sealing rib engages the first channel sidewall and the sealing shoulder. The protuberances can urge the sealing rib downwardly against the sealing shoulder, to thereby form a seal.

A molded plastic closure is configured to provide a plug fit with the top rim of an open top container having an outwardly protruding rim flange. A two-part seal preventing leakage of fluid from the container is provided by means of a ridge structure on the inner wall of the inverted U-shaped channel of the closure peripheral structure as well as a flexible sealing wiper appendage which is formed integrally with the top of the inverted U-shaped structure and which deformingly contacts the top surface of the container rim when the rim is essentially fully inserted into the U-shaped channel. The wiper appendage is formed to angle toward the inner channel wall in the undeflected condition.

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.
