A folded opening-resistant container includes a cover body, which has an outside that is provided with a grip part, which is connected, in an inside thereof, through a perforation line to a first engaging member; and a box body, which includes a circumferentially surrounding wall and a bottom plate arranged at a bottom inside the wall. A foldable member extends from a top end of the wall. The foldable member has an end that is provided with a second engaging member. The cover body and the box body are combinable and interlockable in a detachable manner. The foldable member is curvable or flexible to allow the second engaging member to engage and combine with the first engaging member, such that when the cover body and the box body are separated, the perforation line is broken and the first engaging member and the cover body are separated from each other.

A paper lid that is mainly made of paper includes a top plate portion extending in a first direction, an inner fitting portion extending in a second direction and being continuous with the top plate portion, a peak portion extending in a third direction and being continuous with the inner fitting portion, an outer fitting portion extending in a fourth direction, facing the inner fitting portion at a distance, and being continuous with the peak portion, and a flange portion extending in a fifth direction, being continuous with the outer fitting portion, and including an end of the paper lid.

Containers for storing food in a storage compartment may include a base portion of the container. The storage compartment is sealed with a film to get the food stored in the storage compartment fresh. The container further includes a reversible lid that is able to attach to the base portion of the container in two different configurations. In a first configuration the reversible lid attaches to the base portion without affecting the seal created by the film. In a second configuration the reversible lid attaches to the base portion when the lid is inverted and the film is removed from the base portion.

A locking mechanism for container and lid thereof may include a container and a lid, and the peripheral edge of the upper opening of the container has a first periphery edge. At least two first coupling portions, which are located at symmetric positions, and at least two second coupling portions, which are located at symmetric positions, outwardly protrude from the first periphery edge respectively. The lid comprises a second peripheral edge at the outer periphery thereof, and the inner surface of the second peripheral edge is configured to couple with and cover the first peripheral edge of the container. At least two first connecting portions respectively protrude from the second peripheral edge at symmetric positions, and at least two second connecting portions, which are located at symmetric positions, outwardly protrude from the second periphery edge respectively.

A lid for an insulated container comprises a flexible gasket configured to facilitate a seal between the lid and an inner wall of the insulated container, and further configured to expand into an interior compartment of the insulated container responsive to a vacuum developing in the interior compartment. A diaphragm chamber is situated opposite the flexible gasket from the interior compartment when the lid is fully engaged with the insulated container. One or more air channels couple the diaphragm chamber to an exterior of the lid. The development of a vacuum in the interior compartment of the insulated container draws a force on the flexible gasket, thereby reducing pressure in the diaphragm chamber. The negative pressure in diaphragm chamber is back-filled with external air, which enters the lid via the air channels. The lid may then be removed without excessive vacuum forces.

The puzzle storage box disclosed herein may comprise an internal locking mechanism designed to challenge ingenuity while being embedded within an assembly of unlimited form potentiality. In one variation, the internal locking mechanism is embedded in a shallow container and may be used for more personal, everyday carry. In another variation, the internal locking mechanism is embedded in a deeper container for increased volume and prominent display. The internal locking mechanism will be incorporated into endless shapes and forms, and its novel method of operation will be respectively conveyed.

A lid for a container assembly is disclosed. The lid is configured for locking engagement with the container such that accidental or unintentional removal of the lid from the container is resisted. The lid includes an outer skirt that overlies the outer surface of the container about an upper rim. The outer skirt includes a plurality of lid locking members that are disposed at spaced apart intervals about the outer periphery of the skirt and extend inwardly, relative to the outer skirt, for engaging an outwardly extending container lip. Disposition of the lid on the container is with effect that the plurality of lid locking members deflect outwardly as the lid is displaced downwardly over the container lip, the lid locking members returning to their inwardly disposed position once clear of the lip. The inward disposition of the lid locking members effects a robust engagement between the container and lid.

Containers for storing food in a storage compartment may include a base portion of the container. The storage compartment is sealed with a film to get the food stored in the storage compartment fresh. The container further includes a reversible lid that is able to attach to the base portion of the container in two different configurations. In a first configuration the reversible lid attaches to the base portion without affecting the seal created by the film. In a second configuration the reversible lid attaches to the base portion when the lid is inverted and the film is removed from the base portion.

A locking mechanism for container and lid thereof may include a container and a lid, and the peripheral edge of the upper opening of the container has a first periphery edge. At least two first coupling portions, which are located at symmetric positions, and at least two second coupling portions, which are located at symmetric positions, outwardly protrude from the first periphery edge respectively. The lid comprises a second peripheral edge at the outer periphery thereof, and the inner surface of the second peripheral edge is configured to couple with and cover the first peripheral edge of the container. At least two first connecting portions respectively protrude from the second peripheral edge at symmetric positions, and at least two second connecting portions, which are located at symmetric positions, outwardly protrude from the second periphery edge respectively.

The present disclosure relates generally to containers and container lids. In at least one embodiment, the disclosed containers and container lids provide a liquid-tight seal with the inclusion of a separately attached ring that generally eliminates material-trapping seams. For example, in certain embodiments, a container and a container ring for attaching to the rim of the container is disclosed. In these embodiments, the container ring attaches to the rim of the container such that a liquid-tight vertical seal is formed, thereby reducing or eliminating material-trapping seams.
