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 partition structure of an internal space of a food storage container includes: a container body having a bottom part and lateral parts surrounding a periphery of the bottom part, wherein a transversal inner edge is formed between the lateral parts, and a longitudinal inner edge is formed between the bottom part and each lateral part; and a partition component, disposed in the container body and composed of plural plate units, each plate unit has a partition plate part and an abutting part, and at least one alignment part having a curvature is extended from each abutting part; wherein a curvature defined by the transversal inner edge being extended from each lateral part and a curvature defined by the longitudinal inner edge being extended from the bottom part to each lateral part are substantially the same as the curvature of the alignment part.

A lid-to-container locking combination maximizes lid-to-container retention and includes a container and a container lid. The container includes an upper container rim and a container wall. The container wall includes a radially outwardly extending indentation or groove located in inferior adjacency to the upper container rim at an inner surface thereof. The container lid includes a rim-receiving groove, a lid wall, and a wall-to-groove resilient portion. The resilient portion traverses a structural distance between the lid wall and the rim-receiving groove and is resiliently actuable intermediate a relaxed configuration and an actuated configuration. The resilient portion includes a radially outer indentation-engaging portion. The rim-receiving groove receives the upper container rim, and the indentation-engaging portion engages the radially outwardly extending indentation when in the actuated configuration. The rim-receiving groove and radially outer the indentation-engaging portion together lock the container lid to the liquid container for cooperatively maximizing lid-to-container retention.

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 container has an upper container edge and a fully circumferential lateral wall and an upper container opening closed by a lid. A latching rim is provided near the upper container edge for connection with a corresponding latching rim provided on the lid. The lid has a lid rim portion arranged above the upper container edge. The lid has at least one extension extending outside the lateral container wall and below the lid lower edge. The extension and container have mutually corresponding fasteners independently releasable of the latching rims. The lid and/or the container has an actuator area different from the fasteners on the lid extension and the container and/or from the lid extension itself. When the actuator area has been actuated, the fasteners between the lid extension and the container are more easily releasable and, where applicable, easier to close.

A package includes a container and a lid. The container may include a tamper evident feature, a child resistant feature, or both.

A container has a base flange on a base, and a lid flange on a lid. When the container is in a closed position the lid flange and the base flange are in juxtaposition and one of the flange edges defines a flange support surface. A lid surface is spaced above an upper base periphery when in the closed position to define a lid volume, and the base section defines a base volume. The flange support surface extends a first distance such that when the volume of the container is loaded with a rated capacity of product and the container is placed in a standing position on a flat surface using the flange support surface and a front base corner as support elements, a center of gravity of the container generates a moment about an axis of the base corner that biases the container in the standing position.

In a container having a lid member coupled to a container body by a hinge, the lid member includes a top surface, an inner ring formed on the top surface, and a projected part is formed on the top surface concentrically with the inner ring and which has an outer peripheral surface provided with an outer peripheral surface projection along the circumferential direction. The container body has a sidewall with a first inner peripheral surface having an inner peripheral surface projection formed along the circumferential direction, and a second inner peripheral surface having an inner diameter different from that of the first inner peripheral surface. When the lid member is closed, the inner ring seals the container body by being fitted to the second inner peripheral surface. The outer peripheral surface projection contacts and slides over the inner peripheral surface projection to lock the lid member the container body.

Provided is a resin container lid in which a trouble such as a crack is prevented while maintaining easiness in opening even under a refrigerating or freezing environment, the resin container lid configured to be fitted to and detached from a resin container, the resin container lid including a flange part configured to be fitted to a container, the flange part being formed at a peripheral edge of the resin container lid, and an opening tab for detachment from the container, the opening tab projecting into an outer periphery from the flange part, with the tab having a flexural strength of 50 to 80 N under an environment of 30 C.

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.
