Abstract: There is disclosed a cover for a container for food, for example, popcorn. The container has a rim on which is sealed an expandable foil cover. A paperboard cover overlies this foil cover and is held in place by a flange on the rim which is bent over or crimped onto the pressboard. The cover has a removable central portion, e.g., formed by concentric half-cut sores, and an annular portion, which is crimped between the flange and the rim. The cover has a pull tab extending beyond this annular portion and the concentric half-cut scores curve up to the pull tab. The pull tab can be folded over on a press core and crimped under the flange. The annular portion comprises an inner and outer zone, the outer one of which comprises a plurality of tabs projecting from the inner zone. These tabs may have different shapes, for example, they are preferably arcuate so as to give the outer zone a scalloped appearance.

Abstract: A liquid tight carton with a pour spout having a tear-off portion separated from spout edge forming panels, and panels forming a top fin seal, by lines of structural weakness.

Abstract: Tear strip structure for the relatively narrow side wall of a relatively flat rectangular paperboard carton. The side wall is defined by an inner folded closure flap and an outer flap folded thereover. The outer flap has a line of weakness extending along its length, between and parallel to its fold line and its free edge. The inner flap has a first cut score line defining its fold line and a second cut score line coincident with the line of weakness of the outer flap. The region of the outer flap overlying the region of the inner flap between the cut score lines is adherent to the latter region and defines a tear strip, an end portion of which is non-adherent and functions as a tab by which the strip may be grasped and torn away, separating the plies of the underlying closure flap between the cut score lines in achievement of removal of the tear strip in predictable, controlled manner.

Abstract: A cook-in carton includes a two-panel wall. The inner one of the two panels is provided with vent openings, and the outer one of the panels extends over the openings and is adhered to the inner panel by tabs on opposed edges thereof. The outer panel includes between the tabs a weakened section and opposed flaps. Parallel score lines are provided in each of the flaps, and lugs are formed on the free edges of the flaps upon removal of the weakened section. The flaps are then foldable, in accordion fashion, followed by insertability of the lugs into apertures aligned therewith, where they are restrained in formation of carton support legs.

Abstract: A dispenser package for holding a stack of nested tapered disposable cups and dispensing them individually. The dispenser package has a generally circular opening in the top wall through which the bottoms of the tapered cups protrude; surrounded by a series of arcuate dispensing jaws interconnected with straight sided segments forming yieldable segments around the periphery of the opening which permit the topmost protruding cup to be pulled through the opening, but which function to restrain the cups immediately below. Slits or knife cuts in the top wall of the dispenser package extend from the opening in the top wall to each of the sidewalls at the mid point of each sidewall to permit loading a stack of cups through the top opening of the dispenser package without tearing of the top wall.

Abstract: A construction for a lined carton, made of carton stock and a liner, the carton comprising a plurality of sidewall panel members and a glue flap. A liner substantially covers the carton stock. The glue flap has a projection on each of its ends, the thickness of a portion of carton stock comprising the projection being thinner than the thickness of the main portion of the carton. The invention includes a blank for forming a lined carton comprising a glue flap which has projections susceptible to being made thinner than the thickness of the main portion of the carton stock upon application of pressure to the projection.

Abstract: Reclosable carbon structure of a generally rectangular configuration is set up from a paperboard blank. A top wall serving as a closure is hinged along one edge portion to the carton and the opposite edge portion of the top wall includes a downturned flap extending over a side wall of the carton. The flap is adhered to the side wall in areas surrounded by discontinuous knife cuts provided on at least the flap or the panel so that, upon opening the closure, the knife cut area is delaminated in a controlled pattern.

Abstract: A liquid tight pouring carton is provided, having a pour spout which is easily opened by removal of a tear tab, and can be fully extended thereafter. The tear tab is provided as part of a sealed fin on the top of the carton; the tear tab having a line of weakness extending through the paperboard, but not into or through the barrier and sealing layers of foil and plastic. Until the tab is removed, the carton is completely sealed to leakage or contamination. Additional features provide for reliable and easy opening of the carton.The invention also contemplates a blank suitable for erection into the carton, and a method of making the blank and erecting and sealing it.

Abstract: A blister card package has a product with an enlarged portion, and a conforming blister. Interference between the resilient blister and the enlarged portion retains the product in the package when the product is subjected to moderate removal forces, such as gravity. The product may also be returned to the package for resilient retainment and storage.

Abstract: A reclosable blister card package is provided, having an insert which rotates inside the blister cavity to present product-holding compartments to the dispensing opening. The insert and blister are cooperatively sized and configured for smooth and efficient rotation of the insert within the blister cavity. Opening features provide the dispensing opening, and reclosure features provide for continuing containment and protection of the unused portion of the product.

Abstract: A recloseable hinged blister card package is provided wherein the clear plastic blister is secured to a paperboard card which is suitably cut-scored along the secured areas to allow ply separation of the card for opening the blister. Improved tensile strength which enhances resistance to inadvertent tearing away of the blister is achieved by use of a bottom panel extension of the card that is folded 180.degree. and secured to the blister flange at the bottom of a product holding portion of the blister. Upon opening, the blister flange at the bottom of the blister remains secured to the fold over extension. The package opens by folding the blister back, the package hinge line being the fold line of the fold over extension.

Abstract: A recloseable blister card package has an opening tab which is bonded to a securing segment of the blister board. The bonded segment provides protection against tampering, and provides controlled tearing of that segment from the remainder of the board when the package is opened. After displacement the backing board has an aperture adapted for insertion of the tab to relock the blister to the board. The product may have an enlarged end and an adjacent board hinge. Interference between the blister and the enlarged end holds the product in the package under conditions which might otherwise be expected to permit it to fall out.
