Overpack drum assemblies are disclosed. The overpack drum assemblies include a container base and a lid that may be securely closed on the base within a range of acceptable closure positions that may be visually indicated. The lid may include at least one leverage bracket for receiving a bar or other leverage tool that facilitates tightening and loosening of the lid. The container base may include at least one indented anti-rotation notch to help secure the container base against rotation during tightening or loosening of the lid. An anti-rotation fixture may be used to resist rotation of the container base.

A height-adjustable container is configured such that an upper body and a lower body thereof are rotated from side to side in a zigzag form while coming into close contact with each other, so that the height of the container can be easily adjusted. The present invention enables the height of a container to be adjusted, whereby it is possible to make better use of a space of a refrigerator, a cabinet, or the like, in which the container is stored.

To provide a container for storing a biological tissue capable of storing the biological tissue with an immersed state with its original form being maintained. A container for storing a biological tissue comprises an inner container used to store the biological tissue, and an outer container which seals and accommodates the inner container. The outer container comprises a gas permeation part which allows sterilization gas to flow into the inner container from outside, or the outer container and the inner container are made of a material which allows permeation of a radioactive ray or an electron beam. The inner container comprises a container having an upper opening and capable of accommodating the biological tissue and a solution which hydrates the biological tissue, and a lid part which closes the opening. The outer container and the inner container are pierceable by an injection needle which injects the solution from outside.

An exemplary container lid with a castellated cork seal is disclosed. In various embodiments, the 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 beverage container having an oval or elliptical cross-sectional shape is provided. The beverage container comprises a beverage receptacle comprising a cavity surrounded by a container wall configured to store a liquid and an open top portion. The beverage container further comprises a lid configured to be attached to the open top portion of the beverage receptacle to cover the open top portion of the beverage receptacle and comprising an opening formed through the lid configured to dispense the liquid. The lid and at least the open top portion of the beverage receptacle comprise an oval or elliptical shape to provide the beverage container with its oval or elliptical cross-sectional shape. The oval or elliptical shape of the beverage container is configured to improve visibility of a user during use of the beverage container.

An expandable and collapsible lid system and method thereof. The system includes at least one container including an opening and at least one corresponding lid. The lid may be operable between an expanded state, a middle state and a collapsed state. The lid includes a flange having a circumscribing lip for releasably sealing the opening of the container and concentric segments. Each concentric segment may be flexibly coupled to an adjacent concentric segment, inner-diameter to outer-diameter, a diameter of the concentric segments decreasing inversely with the distance of the concentric segment from the flange, a concentric segment having a largest diameter being flexibly coupled to the flange. When positioned atop the container, the lid increases a storage volume of the at least one container in the expanded state and forms a pool within the container for nesting of a further container when in the collapsed state.

A beverage container system is described. The beverage container system includes a lid assembly with a slider to selectively close a beverage container. The slider is biased to remain in closed and open positions.

Disclosed is an airtight container in which a lid 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 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.

The invention discloses a vacuum container comprising a storage container, a connecting tray component, a top cap and two one-way exhausters. The connecting tray component air-tightly encloses a container opening of the storage container. The top cap has a pressing part, and the top cap encloses a tray opening of the connecting tray component in a manner that the pressing part is in a position corresponding to the tray opening. One of the one-way exhausters is inserted in a guiding hole of the connecting tray component to form a tray one-way exhaust passage. The other one-way exhauster is inserted in an exhausting hole to form a cap one-way exhaust passage.
