Embodiments relate to a container lid with vent holes that are blocked for storage but automatically unblocked when a container attached to the container lid is heated. The heating of the container lid causes the pressure to build in the container, which pushes up an upper portion of the container lid. When the upper portion of the container lid is pushed up, the vent holes are unblocked and enable air or vapor to escape through the vent holes. In this way, the container lid may seal the container during storage but enables automatic venting during the heating of the container to prevent buildup of excessive pressure within the container.

A container having a canister can be configured to retain a volume of liquid. The canister can be sealed by a lid structure, and the lid structure can have a spout opening. The spout opening may be sealed by a removably-coupled cap. Further, the cap may have a magnetic top surface configured to magnetically couple to a recess on the top surface of the lid for temporary storage of the cap when manually removed from the spout opening.

A container includes a base, a lid, and a hinge that connects the base and lid. The containers may be configured to be vertically stackable in an closed position and still permit venting via vents in the lid of each container. The containers may also be nested in an open position with indentations in the base to facilitate separation of the containers. The indentations may be in one of two positions with an alternating pattern when the containers are in the nested arrangement.

A removable lid for a drinking cup is described. The removable lid has a top side with an ellipsoidal recession having a bottom opening. A baffle wall extends from the perimeter of the bottom opening, and is configured to prevent a beverage from passing through the bottom opening upon sudden movement of the beverage. The ellipsoidal recession may be designed so that a hot beverage being consumed through the removable lid is exposed to more outside air for cooling purposes. The same ellipsoidal recession may be designed to funnel added ingredients into a beverage. The removable lid may have a stirrer opening so that stirrers may be inserted and taken out without lid removal. For additional strength, the surface of the removable lid may be textured to increase its moment of inertia. The bottom opening of the removable lid may be closed using a fitted blocking plug.

A package assembly enables a user to adjust package assembly volume and includes a first (static or dynamic) package body and a second dynamic package body. The first package body has an upper body rim. Each dynamic package body provides a dynamic lid volume and has a rim-receiving groove, a lid wall, and at least one resilient portion. The rim-receiving groove is removably attachable to the upper body rim for defining a dynamic package assembly volume with the package body when in a closed configuration with the first package body. The resilient portion extends intermediate the lid wall and the rim-receiving groove and is resiliently actuable intermediate (a) a relaxed configuration for defining a maximum package assembly volume when in the closed configuration and (b) an actuated configuration defining a minimum package assembly volume in the closed configuration.

A thermoformed packaging system includes a lid comprising a lid screw thread; and a container comprising a container screw thread. The container also includes a chamber for receiving a product, an opening configured to be closed and sealed by the lid. The lid screw thread and the container screw thread are complementary such that the lid can be screwed to the container, thereby closing and sealing the opening.

A box includes a base and a cover which is removably mounted to the base. The base includes a first room defined therein, and a connection strip extends from the periphery of the top opening of the base. A knob is formed on the connection strip. The cover includes a skirt extending from the periphery thereof so as to form a second room between the skirt and the cover. The skirt includes a U-shaped recess formed in the outside thereof such that the knob is engaged with the U-shaped recess. The U-shaped recess includes a U-shaped inside wall formed between two reinforcement ribs and the outside of the skirt to easily accommodate the knob.

The present invention is directed to enhanced content security mechanisms for containers. Further, the invention is directed to containers comprising these enhanced content security mechanisms. In particular, the containers of the present invention comprising the enhanced content security mechanism of the invention offer advanced anchoring of the contents (e.g., baked goods or sensitive devices such as medical devices) of the container by preventing: shifting, tipping, breaking, crumbling, rolling or other movement of the contents; thus securing the contents and preventing damage to the contents, i.e., preserving the appearance and integrity of contents contained within.

A container includes a lid and a base, each having a first and second component of an interlocking interface, the first component having a folding portion, and the second component having a boss. The folding portion has a receiving area to receive the boss and connected to either the lid or base and movable between a position of secure and releasable engagement with the boss and a position of disengagement with the boss. Upon a closing engagement of the lid and the base, a respective portion of the periphery of the base has one of the folding portion and an opposing portion of the periphery of the lid has the other of the folding portion and the boss, so that the respective opposing portions of the lid and base are secured with one another by engagement of the folding portion with the boss.
