A collapsible crate or container movable between an erect configuration and a collapsed configuration, has a crate member having an upper peripheral rim, a bottom member, two hinged and collapsible opposing side walls and two hinged end walls that collectively define an interior volume when the crate member is in the erect configuration, and a lid member with first and second lid portions and a hinge that releasably couples the first and second lid portions. The crate member and the lid member also includes latch member to releasably latch the lid member to the crate member in a use/deployed position and a stowed position.

A stackable container lid includes a top surface defining a flat surface plane without an upward protrusion, at least one recess in the top surface, a bottom surface including a rib structure adjacent a perimeter, and at least one nest segment integrated with the rib structure and protruding from the rib structure. The container lid is readily stackable with other container lids and is suited for handling with automation equipment.

Disclosed herein are child-resistant containers. Also disclosed are methods using the modular containers and methods of storing substances in containers The containers have a glass base and a plastic cap and provide for child-resistant containers. A user can releasably remove the cap from base with a squeeze and lift sequence on the sides of the cap. For example, the user squeezes opposite sides of the container cap, which releases a locking mechanism and allows for removal of the cap by lifting or pulling the container cap off from the container base. The containers are modular and stackable.

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.

A tamper evident container includes a cover with a first interlocking flange with a first tab for opening the container and a first extension joined to the first tab along a first frangible score line, a base with a second interlocking flange with a second tab for opening the container and a second extension joined to the second tab along a second frangible score line, a rim extending around a perimeter of the base, the rim having a flat portion connected to an outer wall, and a flange portion extending from the outer wall portion, wherein a position of the flat portion and the flange portion correspond to a sheet line, and wherein the first and second interlocking flanges, when securely fastened together, prevent access to the first and second tabs, and require more force to separate than to sever the first and second extensions along the frangible score lines.

A closure for a container is described where the container has an open end and a closed end, the closure engaging the open end of the container, wherein the closure comprises: a collar engaging the container; a lid connected to the collar by at least one hinge; wherein to facilitate engagement the collar extends over and surrounds the open end of the container such that an inner surface impinges on, or is immediately adjacent to, an outer surface of the open end of the container; wherein a plurality of beads extend outwardly from the inner surface of the collar to fixedly hold the collar in engagement with the container, wherein said beads are located substantially uniformly relative to each other and occupy less than 50% of the inner surface of the collar.

A tamper evident container includes a cover comprising a first interlocking flange with a first inner tab and a first outer tab separated by a first severable line and a base comprising a second interlocking flange with a second inner tab and a second outer tab separated by second severable line, where the first and second interlocking flanges are configured to be fastened together and the container is configured to be opened by separating the first and second inner tabs from the respective first and second outer tabs while one of the first and second outer tabs remains attached to the container and another of the first and second outer tabs is separated from the container and remains attached to the one of the first and second outer tabs.

A lid for outfitting a container is provided. The lid includes a cover shell defining a first cavity, a first lid rim defining an opening, and a hinge member constructed to pivotally interconnect the first lid rim with the cover shell. The cover shell releasably lockable to the first lid rim.
