The container includes a base and a lid pivotally coupled to the base. The base includes a bottom wall and a peripheral wall, where a plurality of receptacles are defined in the peripheral wall. The peripheral wall is configured to be moved from a relaxed position to a flexed position by applying a first force to a first portion of the peripheral wall in a first direction and a second force to a second portion of the peripheral wall in a second direction. The lid includes a top wall and a plurality of projections. In the relaxed position, the lid is configured to engage the receptacles so as to retain the lid in a closed configuration. The container is configured to be moved from the closed configuration to an open configuration by moving the lid in a third direction while the peripheral wall is in the flexed position.

A package includes a base, a lid, and a locking mechanism. The locking mechanism includes an arm and a flexible member. The arm extends from the lid and has a first engaging structure. The member includes a flexible rib connected to a base floor, and a second engaging structure and a contact structure on a rib outer surface. The member flexes in response to a first force applied in a first direction to the contact structure and relaxes in response to absence of the first force. The member engages the first and second engaging structures based on the member being relaxed while the lid is closed. The member disengages the first and second engaging structures based on the member being flexed while the lid is closed. The lid may be opened based on applying a second force to the lid in a second direction while the member is flexed.

The package includes a base, a primary lid connected to the base via a first hinge, the primary lid and the base defining a primary storage area when the primary lid is in a closed position, a first locking mechanism, and a second locking mechanism. The first locking mechanism and the second locking mechanism each include a flexible member including a first and second segment connected by an elbow, the first segment being connected to the primary lid, a distal end of the second segment including a contact structure, the second segment including a first engaging structure, a second engaging structure on an interior wall of the base, the flexible member being in a first position when the primary lid is in the closed position, the second engaging structure being retained by the first engaging structure to lock the primary lid onto the base in the closed position.

The invention relates to the field of storage containers used for the accommodation and delivery of eggs or similar fragile items. The technical result allows the egg trays based on expanded primary and/or recycled (obtained from polyethylene terephthalate waste) polyethylene terephthalate to be recycled as many times as one sees fit. This technical result is achieved by the whole set of essential features. The essence of the invention is that an egg storage tray comprises a base having storage compartments on an inner side of the base, a lid pivotally connected to the base, and a latch configured as a hole provided in the lid and a protrusion provided on the base. The base with the latch and the lid are made of expanded polyethylene terephthalate having a density ranging from 100 kg/m.sup.3 to 900 kg/m.sup.3 and an intrinsic viscosity ranging from 0.5 dl/g to 1.0 dl/g.

A snap-action non-separable connection between the lid and container, incorporating snap-action profiles formed in the top part of the container around the opening for filling the container, and snap-action profiles formed in the lid, where the said profiles interlock, is characterised in that the snap-action profiles in the top part of the container are formed on the front surface of that part into segments which do not contact one another, where formed on the side surface of each segment is at least one snap protrusion and where in the top part of the lid are slots on the side surface of which formed is at least one snap ledge, and where the number of the slots in the lid is equal to the number of the said segments.

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.

Sterilization packaging systems with features for sealing a volume against an ingress of contaminants are provided. Such features include a sealing assembly including a gasket and a sheet of filter material. The sealing assembly seals a lid to a seal rim of a base. The gasket has an upper surface, outer edge, and inner edge. The sheet of filter material extends from an inner edge of the gasket, and the gasket completely surrounds the sheet of filter material. The upper surface of the gasket comprises a plurality of indentations that define channels to facilitate delivery of a sterilization agent through the filter material. A sterilization assembly including a lid having a plurality of protrusions in its upper surface and a sliding-lock system for sealing and locking the lid to a container base is also provided.

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 food container with vents on handles includes a box and a cover. The box includes a box wall and a receiving room. Two opposite sides of the box wall are provided with a pair of handle portions. Each handle portion is extended with a bent section from the box wall toward a direction which is bent away from the receiving room. An upper portion of each bent section is formed with a venting space communicating with the receiving room. The cover is removably fastened to the box to cloak the receiving room and includes a cover plate, a pair of handle lids and sliding seals. The handle lids can be fixed to the handle portions to cover the venting space. Each handle lid is provided with vents. The sliding seals are separately disposed in the handle lids to be capable of selectively cloaking the vents.

A storage container includes a container body, a lid, and a dividing member. The container body defines an accommodating space that has a top opening. The lid is removably disposed on the container body, and has two covering sections that cooperatively cover the opening. Each one of the covering sections is independently operable to uncover a part of the opening. The dividing member is removably disposed in the accommodating space for dividing the accommodating space into two compartments.
