Inhibiting spoilage of items is achieved by providing a container having an environmentally controlled storage compartment sealed form the external atmosphere and a reaction medium in a separate compartment in fluid communication with the storage compartment.

In accordance with one embodiment of the invention, there is provided an improved disposable aluminum lids configured for use with a pan. The lid has a continuously rolled lip around a skirt that when placed on the pan is bent to secure the two together. The rolled lip around the entire periphery of the skirt includes both the sides and the corners of the improved disposable aluminum lid. This significantly reduces the possibility of cuts and injuries to the user with securing the lid to the pan or removing it therefrom.

A storage box for property storage having an open box side surrounded by an upper edge and closed by a lid engaged to the box edges to prevent the box from disengaging from the lid. The lid surroundingly engaging the upper edge of the box along a horizontal box flange around the perimeter of the open box side. A vertical box flange on three sides of the horizontal box flange surrounding the upper edge. A lid on the storage box. The lid having a box edge rail engagement for surroundingly and removably engaging the vertical box flange of the storage box.

A lid component for a paperboard packaging container, the lid component comprising a lid part and a connecting part, the lid part comprising a top portion and a side wall portion, the top portion having an outer lid surface, an inner lid surface opposite to the outer lid surface, and a peripheral edge surrounding the outer lid surface; and the connecting part comprising an upper portion and a lower portion and having a lower edge surface. Stacking members are arranged on the outer lid surface and comprise a lid component stacking step and a container stacking step, the lid component stacking step being arranged laterally outboard and below the container stacking step. The lower portion of the connecting part is adapted to be supported by the lid component stacking step. A lid component comprising a locking arrangement and paperboard packaging container comprising a lid component are also disclosed.

Closure unit for a container, comprising a substantially flat cover element, for closing off the aperture in the container which cover element is provided with a tension element, for creating a pressure force that presses the cover element to a rim that surrounds the aperture of the container. The invention also prides a closure unit and a container as well as to methods for closing and opening a container with such a closure unit.

A container and a method for forming a container that has a base flange on a base, and a lid flange on a lid. One or both of the base flange and lid flange have a relief pattern. For each flange that has the relief pattern, the relief pattern imparts rigidity in the flange to resist flexure of the flange relative to the portion of the container (the base or lid) to which the flange is attached.

A lid with a flexible inner seal portion for fitting onto containers having differently angled inner walls.

A drinking cup lid, comprising: a center cover portion; a rib ring formed at the external circumferential edge of the center cover portion, the rib ring having a drinking recess, the external edge of the drinking recess being open while an insertion opening is disposed at the internal edge thereof, the bottom surface of the drinking recess being provided with a drinking opening; a vent hole formed in the center cover portion or in the rib ring; a snap ring portion formed at the external circumferential edge of the rib ring for a snap fit to the drinking cup; and a plug connected by a flexible strip in a hanging way to the external circumferential edge of the snap ring portion, the plug having a plug portion, a hand-held portion and an insert portion. Before use, the insert portion of the plug is fitted first into the insertion opening. Thereafter, the plug portion is fitted to the drinking opening. In this way, the laborious plug-and-pull problem of the conventional splash proof plug is resolved. As a result, the splash proof plug according to the invention can achieve an effort-saving plug-and-pull effect.

A stackable lid for a container includes a main body having an interior portion circumscribed by a lip. The interior portion has a plurality of raised surface features, a plurality of channels, and a plurality of connecting bridges formed therein. A plurality of bosses extend from the interior portion of the main body. Each of the bosses includes a plurality of sidewalls. At least one support feature depends from an interior surface of at least one of the bosses.

A concave lid including a depression, such as a notch compatible with a user's finger or thumb to apply pressure on the concave lid toward a glass. The depression may include anti-slip ridges to keep the user's fingertip from slipping when pressure is applied by the user. The concave lid has a portion for indicia that is readable from the outer surface of the concave lid. The concave lid may include a textured portion on its lower surface, such as a band of texture, to create friction and prevent the concave lid from slipping with respect to the glass. The concave lids are preferably stackable and made of clear plastic or glass.
