Abstract: A package may include a front panel and a back panel opposite the front panel, each including a top end and a bottom end, and a first side panel and a second side panel each extending between the front panel and the back panel. The front panel includes a front panel perforation extending from the first side panel to the second side panel. The back panel includes a back panel perforation extending from the first side panel to the second side panel. The front panel perforation and the back panel perforation may be disposed between the top and bottom ends of the front and back panels, respectively. The first side panel includes a first side panel perforation extending from the front panel perforation to the back panel perforation. The second side panel includes a hinge element extending from the front panel perforation to the back panel perforation.

Abstract: Transport and conservation packaging is made from a blank sheet of material such as cardboard or corrugated cardboard. The packaging can be used for the transport of fresh food such as fish or meat, either alone or with the addition of ice. The packaging includes a bottom and relatively hermetic side walls, to withstand exudates and/or melting ice and to improve retention, possibly channeling evacuation. The packaging further includes a lid adapted to the base.

Abstract: An easy to carry lightweight carton for shipping and storing cut paper and for providing rapid and easy access to the paper when the carton is opened. The carton has a base portion and a lid pivotally attached to the base portion. A front wall of the carton may be pivoted down when the lid is pivoted up to facilitate access to the contents of the carton for ease of unloading of paper from the carton. A carry handle is built into the base portion to facilitate carrying of the carton. The carry handle position causes the center of gravity of the carton to be closer to a user's body when carrying the carton. The carton may be re-closed after it is opened.

Abstract: 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 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.

Abstract: A substantially crimpless and monolithic paperboard container lid and method of making same is provided. The lid comprises a single contiguous molded paperboard body configured to conformingly couple to a top periphery of a container for covering the container's opening. The body includes a sealing ring located adjacent the body's periphery. The sealing ring includes a sealing channel composed of a radiused cross-section that extends to a tangent ring terminating with a tab ring. The radiused cross-section and tangent ring assist providing a snug fit between the lid and the container. Despite being made from paperboard, the lid does not include one or more substantial crimps in the sealing ring. Having no substantial crimps, the lid fits onto the container and prevents fluid from leaking between the container's periphery and the lid.

Abstract: The cup has a lid portion extending up from one side of the cup, configured to flip down into the body of the cup, along a first score line, going from convex to concave, so as to close the otherwise open top of the cup. Flaps extend preferably from the lid portion near its lateral intersections with the cup body outwardly from the cup, or alternatively from the cup body in the same area, but inwardly. In either case, the flaps overlie what might otherwise be a small gap between the lid and the cup body in that area. This reduces any possibility for liquid to escape via that small gap. In the case of the flaps extending outwardly from the lid, the flaps also tend to act as stops against excessive downward rotation of the lid, and provide an easy way to lift the lid to open the cup, if desired.

Abstract: A paperboard box is made of a piece of paperboard with split lines and folding lines to form a shape like a boat so as to make the food or the like inside worthwhile and enhance the purchase desire of the consumer. Further, the paperboard box is easy to be disposed after using without creating a problem of contamination to the environment.
