A container is described comprising: a base comprising a mouth, a first edge obtained around the mouth and a second edge connected to the first edge by a lower wall; a cover capable of being closed again on the base, the cover comprising a base wall and an edge connected to the base wall and adapted to be assembled with interference on the first edge of the base; the lower wall further comprising a breaking line along which the separation of the second edge from the first edge and from the base is adapted to occur to allow opening the container providing evidence of the occurred opening, the first upper wall of the first edge having sizes greater than those of the opening of the edge, to assemble with interference the first edge of the base inside the edge of the cover when the cover is closed on the base.

A tote assembly has a tote and a lid. The tote has a sealing channel formed in a lip that extends around a perimeter of a tote opening. At least one drain is formed in the lip and is adapted to direct a fluid away from the sealing channel. The lid has a center portion, a collar disposed around the center portion forming a perimeter of the lid, and a sealing rib formed in the collar that extends around the perimeter of the lid. The collar forms an interference fit with the lip of the tote. The sealing rib is configured to be disposed in the sealing channel to form a fluid tight seal. The fluid-tight seal between the tote and lid ensures the contents of the tote remain dry in an otherwise wet environment or conditions.

An airtight container has a lid which is easily opened by the principle of the lever thus preventing broth from splashing out when the lid is opened. The airtight container includes a container body having a latching bump and a bent flange, a rotating knob connected to the flange and having an opening-closing plate and a step portion, and a lid having a latching protrusion, a downwardly bent flange and a lid extension portion, wherein, when the rotating knob is just rotated upward in a state where the lid is coupled to the container body, the opening-closing plate lifts the lid extension portion by the principle of the lever while the step portion prevents the lid extension portion from spreading outwards, thereby allowing the latching protrusion to be released from the latching bump and the lid to be opened from the container body.

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 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.

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 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 waterproof container is disclosed. The container can include first shell and a second shell; a first rim extending around the first shell; a second rim extending around the second shell; and a latch for securing the first shell to the second shell and defining an enclosed storage volume in a mated position. The first shell can include a grip projection adapted for opening the container from a mated position. The latch defines a latch recess adapted for receiving the grip projection when the latch secures the first shell to the second shell in the mated position. The second rim can include a continuous recess, having a pair of continuous sides and a seal ridge between, but spaced apart from, the continuous sides, while the first rim can include inner and outer continuous sealing ridges that fit over the seal ridge and between the continuous sides.

A cover for a container that includes a lid portion and a collar element. The lid portion having a main body section surrounded by a peripheral sealing shoulder. The collar element having a peripheral collar sealing shoulder that includes a collar groove and wherein the lid portion is connected to the collar portion through a hinge element. The lid portion, collar element and hinge portion are formed as a unitary structure and the lid portion articulates from an open positon in which it is spaced apart from the collar element to a closed position wherein the peripheral bead sealing shoulder of the lid portion engages with the peripheral collar sealing shoulder of the collar element.
