Abstract: A clamshell container having a cover portion and a tray portion connected by a living hinge wherein the corners of the sidewalls in at least the tray portion are perforated or scored to permit easy separation by a user to create a substantially flat serving tray is described.

Abstract: A collapsible, disposable food container for containing a food product. The food container includes a main body portion being selectively positionable between a collapsed and stowed configuration and an expanded and operable configuration, and a bottom portion extending from the main body portion. In some embodiments, a separable strip is provided and formed in at least one of the front panel, the back panel, and the one or more side panels. The separable strip is removable, in some embodiments, to bifurcate the associated panel to permit the main body portion and the bottom portion to be laid substantially flat without removal of the food product.

Abstract: A packaging carton box structure includes a first sheet and a second sheet, and a pre-tearing portion is disposed on a first side plate of the first sheet. After the first sheet and the second sheet are bent, an object is packaged, and then, after the packaged object is placed on a placement plane, the pre-tearing portion is torn, so as to take out the object along a direction parallel to the placement plane, which is time-saving and labor-saving, and further prevents the object from falling off to result in damages when being taken out.

Abstract: A packaging box (10) includes a pair of lids (2, 3), and the pair of lids (2, 3) have tongues (2b, 3b) extending from their heads and lid gluing portions (2c, 3c) arranged in specific areas on the outer surfaces of these tongues (2b, 3b). A body (1) of the packaging box (10) has a pair of body gluing portions (1f, 1g) individually glued to the lid gluing portions (2c, 3c) and at least one transverse split-open portion (5) for guiding a fracture in a side face of the packaging box (10). Both open-side ends (1e) have side-end split-open portions (6, 7) arranged so as to surround the body gluing portions (1f, 1g). Thus, even if the tongues provided at the heads of the lids are glued to side plates, the packaging box can be easily and accurately split and spread.

Abstract: A cardboard container which can be easily opened without tools and which, when opened, collapses and lies flat without further handling to permit ready access to the container contents and which facilitates the recycling or disposal of the container.

Abstract: A container having a plurality of selectable volumes which selectable volumes are made by inwardly folding sides and ends of the container along selectable foldable creases. The invention may also be a container in unassembled form. Preferably the container, when assembled, is rectangular in cross sectional shape, and preferably formed from layered cardboard material. The assembled container has two side panels attached to two end panels and to the bottom portion along the panel edges thereby forming the container.

Abstract: A paperboard container has opposed or weakened lines extending from top to bottom in a pair of end walls. The weakened lines are spaced inwardly from the corners of the container. To collapse the container for retrieval and recycling the tops of the end walls are grasped and sufficient force exerted causing the weakened lines to tear from top to bottom.

Abstract: A cooking utensil has a base portion and a wall portion, wherein at least the wall portion is disposable after a single use. The wall portion includes a score line for irreversibly forming an opening in the wall portion. Tabs may be provided on either side of the score line for facilitating opening of the wall portion along the score line.

Abstract: A collapsible container for disposal provided. The container contains a body member, top member and bottom member. The body member has an upper and lower portion. The top member is connected to the upper portion, while the bottom member is connected to the lower portion. The design of the body member permits the top and bottom member to be opened. For disposal purposes, once the top and bottom members are opened, the body member is folded upon itself and then over itself. The bottom member is then folded over the body member and the top member is folded over the bottom member.
