Abstract: Disclosed are rigid multi-compartment recloseable packages. A package may comprise a rigid tray comprising a product surface to hold food products. The tray may comprise a raised lip along a perimeter of the product surface to laterally secure the food products thereon. The tray may have a tray skirt horizontally extending outward from a top edge of the lip, and dividing features upwardly extending from the product surface to form distinct compartments on the product surface for receiving the food products therein. Furthermore, such an exemplary package also comprises a recloseable rigid lid having an upper surface substantially coextensive with the product surface, and at least one sidewall downwardly extending from the upper surface. The lid may also comprise a lid skirt horizontally extending outward from a bottom edge of the at least one sidewall, where the lid skirt is coextensive and complimentary in shape with the tray skirt.

Abstract: The disclosed principles provide for a welding technique welding the flanges of a rigid lid sealed onto a rigid tray, such that the two may be easily separated but still repeatedly reclosable such that the rigid package may be reused. For this unique and advantageous ultrasonic welding technique, the disclosed principles provide for the inclusion of a unique delamination layer between the similar rigid materials used for forming the flanges of both the lid and the tray. The disclosed principles provide for the delamination layer to be provide on one or both of the two rigid materials, but behind the seal interphase area so that the hermitic seal may still be created. This delamination layer operates such that it peels apart (i.e., delaminates) as the ultrasonically sealed rigid material of the lid flange and rigid material of the tray flange are pulled apart while opening the package initially.

Abstract: A nestable food package, is provided. The food package has a base and a lid with a concave portion configured to receive the base of another food package.

Abstract: An expandable food package with a removable lid, is provided. The food package has a bottom, an inner sidewall and an outer sidewall. The inner sidewall and outer sidewall are connected by a series of living hinges that allow the package to be converted between an expanded configuration and collapsed configuration. A lid may be sealed to one or both of an inner rim and an outer rim when the package is in collapsed configuration.

Abstract: A packaging carton for a food product is disclosed, where the carton includes a front face, a back face, two side faces, a top face and a bottom face, where these faces define an interior storage cavity, at least the back face of the packaging carton includes a perforation defining an opening flap and the opening flap may be permanently removed by separating the opening flap from a face or faces of the carton along the perforation to define an access opening that allows access to the interior storage cavity. A method of making a packaging carton for a food product is also disclosed.
