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. tamper evident container includes a cover having a first interlocking flange with a first tab for opening and closing the container and a first extension joined to the first tab along a frangible score line, a base having a second interlocking flange with a second tab for opening and closing the container and a second extension joined to the second tab along a frangible score line, the first extension including one or more first interlocking elements and the second extension including one or more second interlocking elements, where the first and second interlocking elements, 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 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.

An expandable triangular pizza storage container with a set of microwaveable triangular trays for the separation, microwaving and serving of individual slices of pizza. The storage container has a series of concentric triangular compartments that are expanded from a flexible polymer, accordion-style container body. The lid also has a triangular configuration with a replaceable compressible gasket, a set of four locking wings extending from each side that frictionally engage a rigid triangular top ring of the container body, and a central vent. The trays may incorporate uniform concave pockets to facilitate crisping of the pizza crust in the microwave and be of a solid or cored design, of microwave and dishwasher friendly material.

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 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.

Containers for storing food in a storage compartment may include a base portion of the container. The storage compartment is sealed with a film to get the food stored in the storage compartment fresh. The container further includes a reversible lid that is able to attach to the base portion of the container in two different configurations. In a first configuration the reversible lid attaches to the base portion without affecting the seal created by the film. In a second configuration the reversible lid attaches to the base portion when the lid is inverted and the film is removed from the base portion.

An apparatus having a body portion and a tab coupled to the body portion via a hinge, wherein the tab comprises a first side edge and a second side edge, and further wherein the tab has a closed position covering an opening in the body and an open position where the opening is uncovered, wherein in the first condition the tab has a first width, and when the tab is in a second condition, the tab has been widened to a second width greater than the first width, and the tab has an outer radial edge that extends towards, but short of, the outer portion of the apparatus, and wherein a flat surface is positioned around the opening, and when the tab is in the second condition the side edges of the widened tab extend over the flat surface when the tab is in the closed position.

A hybrid package (10) is provided and comprises a wall (20) formed from a paper or paper-based material and a frame (15) formed from a plastics material. The frame (15) includes a step which is positioned against a free edge of the wall, whereby one or more exposed edges of the wall are protected by the frame.
