A container assembly includes a first component, a second component, and a third component. Each component has an outer wall, a side wall extending upward from the outer wall, and a lip extending outward around a perimeter of the side wall. Each of the lips of the components are releasably lockable with another lip to form a modular container assembly.

A storage container preferably includes a container portion and a lid. The container portion preferably includes a bottom wall, a vertical peripheral wall and a female peripheral sealing cavity. The vertical peripheral wall extends upward from an outer perimeter of the bottom wall. The female peripheral sealing cavity extends around an entire perimeter of the vertical peripheral wall. The lid includes a top wall and a male peripheral sealing projection. The male peripheral sealing projection includes a partially curved cross section, which is sized to be sealingly received by the female peripheral sealing cavity. A top inner perimeter of the male peripheral sealing projection extends from an outer perimeter of the top wall. The male peripheral sealing projection extends around an entire perimeter of the top wall. The shape of the lid and storage portion preferably include a substantially rectangular shape with four curved corners.

A storage and transportation device, which relates to the technical field of storage and transportation apparatuses are disclosed. The storage and transportation device comprises a cover, a supporting plate and a sealant. The supporting plate covers an opening of the cover to form a space for accommodating an item to be transported. The storage and transportation device further comprises a first sealant groove and a second sealant groove arranged at a sealed junction between the cover and the supporting plate, the sealant is contained in each of the first sealant groove and the second sealant groove, and the two parts of the sealant are connected.

A lid for mounting on a cup opening defined by a brim of a cup body includes a cover having a substantially planar portion and a recessed opening disposed on the cover; a side wall disposed around the periphery of the cover; a flange extended from the bottom edge of the side wall and forms a trench space for accommodating the brim of the cup body when the lid is mounted on the cup opening; and a breathable film disposed below the substantially planar portion and covered the recessed opening of the cover. The cover and the breathable film of the present lid are integrally formed into a single piece.

Provided is a food container which includes a box body with an opening and a box cover; the box body includes a box bottom and a box wall; a top edge of the box wall extends toward the outer side of the box body to form a first connecting strip; the first connecting strip is provided with a groove in the middle; the box cover includes a cover plate and a side wall; a top edge of the side wall extends toward the outer side of the box cover to form a second connecting strip; the middle of the second connecting strip protrudes to form a convex rib; when the box cover covers the opening of the box body, the convex rib of the box cover is embedded into the groove of the box body to form a seal structure. The food container is good at sealing performance.

Container includes a base and a lid. The base has a base rim forming a base channel including a bottom wall, an inner sidewall, and an outer sidewall to define a channel space, a lock projection extending into the channel space from a first portion of the base rim, and a lever projection extending substantially outwardly from a second portion of the base rim. The lid has a lid rim forming a lid channel including a bottom wall, an inner sidewall, and an outer sidewall. The lid has a closed position in which the lid channel is aligned with and disposed at least partially within the channel space. The lever projection is configured to pivot upon application of an external force to cause the lock projection to move out from the channel space and to urge at least a portion of the lid rim out of the base channel.

A lid with a flexible inner seal portion for fitting onto containers having differently angled inner walls.

Non-cylindrical plastic paint container with handle.

A food storage unit provides a container and a cover which use an interference fit to snap the cover onto the container. The two engage with each other by a first lip (of the container) and a second lip (of the cover). The lips are configured to have an obtuse angle of 95 degrees, helping to create a better fit between the two. The second lip deforms when placed over the first lip; the resulting pressure and friction helps to seal the cover to the container. To help create a more secure attachment, a latching member is connected to the second lip. The latching member is positioned just below the first lip, such that the cover cannot be lifted straight up until a person manually moves the latching member away from the first lip. This helps prevent the cover from accidentally coming loose from the container.
