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.

An end cap, a collectible card protective assembly, and a storage system generally comprise a cover sized to extend over and close the open end of a collectible card holder, and an engagement member configured to engage the collectible card holder and releasably secure the cover to the collectible card holder. The end cap prevents removal of the collectible card from the pocket when the cover is secured to the collectible card holder by the engagement member.

Provided is a lid assembly for a container. The lid assembly includes a lid formed of a first material and a seal formed of a second material and being integrally formed with the lid. The lid can be attached to the container such that a radially outwardly extending flexible lip of the seal compresses against an inner surface of the container to seal the lid assembly to the container.

A lid for a container assembly is disclosed. The lid is configured for locking engagement with the container such that accidental or unintentional removal of the lid from the container is resisted. The lid includes an outer skirt that overlies the outer surface of the container about an upper rim. The outer skirt includes a plurality of lid locking members that are disposed at spaced apart intervals about the outer periphery of the skirt and extend inwardly, relative to the outer skirt, for engaging an outwardly extending container lip. Disposition of the lid on the container is with effect that the plurality of lid locking members deflect outwardly as the lid is displaced downwardly over the container lip, the lid locking members returning to their inwardly disposed position once clear of the lip. The inward disposition of the lid locking members effects a robust engagement between the container and lid.

The tamper evident container includes a base with a base hinge panel and a lid with a lid hinge panel. A hinge connects the panels. A frangible line extends from an edge of the lid hinge panel to a first point on the panel and then outwardly to the hinge. The frangible line crosses the hinge and extends inwardly to a second point on the base hinge panel. From the second point the frangible line extends to an edge of the base hinge panel. When the container is initially sealed, the frangible line separates upon the application of an upwardly directed force to a first portion of the lid hinge panel while a second portion of the lid hinge panel is held in a fixed position or moved downwardly. The separation of the frangible line creates two grasping portions that can be used to pull the lid from the base.

A seal box with a good sealing effect and easy to open comprises a box body and a sealing cover, wherein the box body is formed with an opening, a sealing mechanism is disposed between the opening of the box body and the sealing cover, the sealing cover is detachably mounted at the opening of the box body, and the sealing mechanism is in a locked and sealed state; and a quick opening mechanism is further disposed between the box body and the sealing cover. By means of the quick opening mechanism, users can easily and quickly operate the operating end of an opening element to force the parts, between the area where the opening end is located of the sealing cover and the opening of the box body, of the sealing mechanism to be separated.

A container lid and base assembly includes lid and base stacking features, as well as base chamfers that align with vents provided in the lid. When a plurality of the container assemblies is stacked, the lid and base stacking features nest with each other, while the chamfers align with corresponding vents in the stacked assemblies so that none of the vents is blocked by a next-higher container assembly. The stacking features can be centrally located, and the vents can be peripherally located. A plurality of the container assemblies can have differing sizes and/or shapes, while including mutually compatible stacking features, thereby enabling container assemblies of differing sizes to be stacked without blocking any of the vents thereof. The vents can be holes or “C” vents. The lid and/or base can be manufacturable by thermoforming. The lid and base can be separate, or joined by a hinge.

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 backward-folded opening-resistant container structure includes first and second casing members combinable with each other. The first casing member has an outer side to which a foldable member that includes an insertion trough and an engaging member is connected. The second casing member includes a grip portion having a notch. A break-away unit includes a planar portion connected to the notch by means of a perforation line and a fastening portion in the form of a hollow cylindrical body having an end formed with an opening connected to the planar portion. The insertion trough and the fastening portion are combinable with each other, and the foldable member is foldable to have the engaging member inserted into the opening. When the first casing member and the second casing member are separated, the perforation line is broken and the break-away unit detaches from the second casing member.

A lid for a bucket comprises a center portion and at least one side portion. In some embodiments, the side portion is removably coupled to the center portion. In some embodiments, the side portion is hingedly connected to the center portion and includes at least one cutout suitable for receiving a bail mount of the bucket. The hinged connection between the center portion and the side portion may be on an axis substantially perpendicular to an axis on which plural bail mounts of the bucket lie.
