The box body includes a plurality of side walls respectively including a plurality of outer and inner portions, an annular groove formed on the inner portions, and an annular protrusion portion. Each outer portion has a level difference with the corresponding inner portion. Any two adjacent ones of the side walls form a corner portion. An outer surface of each corner portion forms a sharp corner. The annular groove is arc-shaped at a position corresponding to each corner portion. Each corner portion includes a hollowed-out area. The cover body includes a main body in a polygonal shape with sharp corners, an annular protrusion portion protruding from the main body, and an annular groove. The annular protrusion portions extend into the annular grooves, so that the cover body is sealedly joined to the box body.

A tamper-evident container and method is disclosed. The tamper-evident container includes a base portion and a lid (or cover). In an untampered with state, one edge of the lid is removably connected to one edge of the base portion. Namely, the lid includes a tamper-evident tab, wherein the tamper-evident tab includes a grasping overhanging portion that is flanked by at least one breakable joint and wherein the lid is removably connected to the base portion via the breakable joint of the tamper-evident tab. Further, the tamper-evident container comprises an interlocking interface between the base portion and the lid. A method of using the tamper-evident container is provided.

A one-piece thermoformed food package comprises a base with a peripheral male rim and, connected to the base by a hinge, a lid having a peripheral female rim channel. The corners of the male rim of the base includes a first set of tabs extending inwardly from the rim towards the interior of the base, and a second set of tabs extending outwardly from the opposite side of the rim towards the exterior of the base. The tabs are configured to engage corresponding hidden recesses formed in the side walls of female rim channel of the lid. A plurality of ridges in the sidewalls increases structural stability, and assists in mating the base with the lid.

An electrical connection box includes a box main body having an opening portion in an upper end portion at a time of installation, and an upper cover that blocks the opening portion at the time of installation. The box main body has an insertion wall portion continuously formed along an outer circumference of the box main body in the upper end portion at the outer circumference of the box main body. The upper cover has a groove portion continuously formed along an outer circumference of the upper cover in a lower end portion at the outer circumference of the upper cover. Here, the insertion wall portion is inserted into the groove portion from lower side when the opening portion of the box main body is blocked. At least one rib protruding downward from a bottom portion of the groove portion is formed in the groove portion.

A container includes a base and a lid. The base includes a lock channel. The lid includes a rim. The rim of the lid is configured to engage with the lock channel in the base to retain the base and the lid in a closed position. The container also includes a first tab on the base and a second tab on the lid. The first tab extends outward approximately perpendicular to a vertical direction. A portion of the second tab may be deflected upward at an oblique angle when the lid and the base are in the closed position. A first portion of the second tab may be received within the first tab and a second portion of the second tab may extend upward and out of the first tab at an oblique angle when the lid and the base are in the closed position.

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 tamper evident container includes a box and a lid. The box has a bottom, an annular wall projected from bottom, and a box flange projected from the annular wall. A first tab is connected to the box flange. The lid has a cover piece and a lid flange. A second tab is connected to the lid flange. The second tab has a root section, a neck section and a head section in sequence, wherein a width of the second tab is gradually decreased from the root section to the neck section, and then is gradually increased from the neck section to the head section. The second tab has a portion connected to the first section, on which a weaken line is provided.
