In various embodiments, a container lid with a castellated cork seal includes a plurality undulating u-shaped ridges that form peaks and troughs throughout a channel. The undulating u-shaped ridges throughout the channel may provide a surface for receiving a bottom of a separate container in a stacked configuration. In certain embodiments, when the lid is secured on top of a container, the u-shaped ridges protrude downwardly into the container for providing cantilevered support. In particular embodiments, the exemplary container lid includes detachable tear strips along a side wall of the container lid. Removing the tear strips allows access to one or more lift tabs for applying upward leverage to the exemplary container lid for removing the lid from a container.

A storage container includes a container body and a lid that has a first lid portion, a second lid portion, and a hinge portion between the first and second lid portions. Two sides of the hinge portion are formed with a first inclined surface connected to the first lid portion and a second inclined surface connected to the second lid portion, respectively. The first inclined surface is provided with at least one first engaging unit. An outer wall surface of the first engaging unit has a first stopper. The first stopper is parallel to or perpendicular to a horizontal plane of the lid. The second inclined surface is provided with at least one second engaging unit. An inner wall surface of the second engaging unit has a second stopper. The second stopper is perpendicular to or parallel to the horizontal plane, and is perpendicular to the first stopper.

A container including a base and a lid that is releasably attached to the base. The lid includes a channel that extends around a perimeter of the lid. At least one inlet opening provides fluid communication between an interior of the container and the channel, and at least one outlet opening provides fluid communication between the channel and atmosphere.

A lid for a drinking vessel is described. In one embodiment, the lid is an insulated lid configured to engage an opening of a container, where the lid is configured to at least partially retain the liquid within the container. The lid may further include a first opening for exposing the contents of the container to the atmosphere and for drinking from the container if desired. Additionally, the first opening may include an insert designed to reduce the heat transfer between the interior and exterior of the container, while in other embodiments aiding in the equalization of pressure between the interior and exterior of the container. Other aspects and embodiments of the present invention will be apparent from the following detailed description, drawings, and claims.

A container system includes a container having a plurality of sidewalls and a rim extending from the sidewalls at a top of the container. The rim of the container includes a first sealing part and a second sealing part. Parts of the rim extend along arcs as viewed from above the container. The container system also includes a lid for sealing the container, with the lid having a rim that includes a first sealing part that is configured to contact the first sealing part of the rim of the container to form a first sealing area, and a second sealing part that is configured to contact the second sealing part of the rim of the container to form a second sealing area. Parts of the rim of the lid extend along arcs as viewed from above the lid. The container may be tightly sealed by the lid.

A single-walled disposable cooler can include: a body including a base and a plurality of support walls coupled to the base, the plurality of support walls and the base defining an interior cavity of the body, and the plurality of support walls extending upwardly from the base to form an opening at an upper terminus of the body in fluid communication with the interior cavity; and a lid configured to reversibly couple with the body, the lid shaped to cover the opening of the body. The body can be made entirely of a pulp-based material.

A two-piece spill proof open cup is disclosed comprising a container suitable for holding liquids, such as a beverage, and a lid. The container has a sidewall, a neck adjacent the sidewall and an opening defined by the neck. The neck has a flange along an edge of the neck and a plurality of posts adjacent the flange. The lid is adapted to fasten to the container. The lid has an upper surface external to the two-piece spill proof open cup and a lower surface internal to the two-piece spill proof open cup. The lid also has a flap, a lid body with a vent, a hinge connecting the flap to the lid body, a handle on the upper surface and a bead having channels. The bead is integrated into the lower surface. The lid flap is adapted to form a liquid tight seal between the lid and container.

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.

Provided is an automatic air-release box lid, including: a box lid body provided with an air hole, the air hole being configured as a through-hole structure, openings at two ends of the air hole being located on an upper surface and a lower surface of the box lid body respectively; and a fastening lug having a rotating shaft part by which the fastening lug is hinged to the upper surface of the box lid body, the rotating shaft part and one opening of the air hole being arranged corresponding to each other and one above the other, the rotating shaft part having a blocking surface. Further provided is a preservation box, including: an automatic air-release box lid and a box body. The box lid is fitted to cover the box body.
