A blank for a package configured to retain an article therein can be configured to be wrapped around the article to form a circumferential case around the article and have a longitudinal length longer than the article. The blank can be configured to define the circumferential case to include one or more inward protrusions at or near one or more ends of the circumferential case that is configured to extend into the circumferential case above and/or below the article to retain the article longitudinally.

An embodiment of a box is configured to be transformed to include a tapered structure configured such that when the transformed box is inserted into the receptacle, the tapered structure provides a universal fit. An embodiment of an extender is formed by steps including providing a single piece of material having a first edge and a second edge and forming, by cutting the single piece of material, at least one top extension extending from at least one wall and at least one bottom extension extending from the at least one wall such that the at least one top extension is foldable to abut the at least one wall. A method for collecting waste materials includes providing a receptacle and a box, and disrupting the extender. An embodiment of an extender comprises a first wall, a second wall, a third wall, and a fourth wall.

Various blanks are provided for forming sleeves, containers, and other constructs for heating, browning, and/or crisping of a food item in a microwave oven, and for holding and/or transporting the food item after heating. The various blanks, sleeves, containers, and other constructs may include a removable portion defined by one or more lines of disruption that enable the removable portion to be separated from the remainder of the blank, sleeve, container, or other construct.

A carrier includes first and second opposed side walls (16, 20), a bottom wall (12, 24) and a top wall (18). The carrier has an article retention device (L1, L2, L3, L4, L5, L6) for retaining a portion of an article (C) within the carrier. The article retention device is formed in part from the bottom wall and in part from the first side wall. The article retention device includes an anchor tab (52) for engaging with an article and at least one protection flap (56, 58) for protecting the article. The anchor tab and the protection flap define an opening in the carrier through which a portion of the article protrudes.
