Abstract: An overwrapped carton is provided having a tubular body formed from a blank of paperboard cut and scored to provide a plurality of serially connected walls, one of which has a window or dispensing opening cut therein. A thin flexible protective sheet of film is disposed to extend over certain of the walls and the window and has end portions secured to one of the walls and a glue connector flap which secures the walls in a tubular array. The connector flap is formed from the material removed and cut from the wall to form the window, economizing on board material.

Abstract: A hermetically sealable and reclosable package includes a body member of semi-rigid preformed plastic having a first planar marginal portion and a central portion shaped to provide a packaging chamber. A base member has a second planar marginal portion and is adapted to close the packaging chamber. A mat is sandwiched between the body member and the base member, with the mat, body member and base member being of generally similar rectangular configuration. The mat is permanently attached to either the body member or the base member on all four side edges thereof. The opposite side of the mat is permanently attached to either the body member or the base member along one side edge and peelably attached along the remaining side edges. The package is opened by separating the peelable sides so that the body member or the base member may be rotated about a hinge defined by the permanently affixed side edge to expose the products of the package.

Abstract: A reclosable package comprises a body member of semi-rigid preformed plastic with a first planar marginal portion and a central portion shaped to provide a packaging chamber. A base member has a corresponding second planar marginal portion and a central panel to provide a closure for the packaging chamber. The body member and base member are permanently bonded along one pair of adjacent sides of the first and second planar marginal portions. A hinge is situated within the pair of adjacent sides, which automatically locks when the package is open and unlocks when the package is closed. The hinge may comprise a line of perforations with integral locking tabs situated in one of the sides, or in a mat interposed between the sides. Different patterns of cut configurations may be employed as the hinge as long as the hinge includes areas which protrude to hold the package open when the lid is rotated past 90 to the open position.

Abstract: An expandable food such as popcorn is sealed within a pouch formed of a substantially oxygen-impermeable, flexible, synthetic high polymer film which is dimensioned so as to fit for storage and efficient cooking of the food product in an outer bowl-like protective paperboard container. The outer container and pouch can be heated in a microwave oven and the expandable pouch and food is supported and confined in the bowl of the outer container, from which the food can be consumed. The outer container is formed from a unitary blank which can be partially erected and shipped in a flat, knockdown condition to a food processor for filling with the food pouch. The base of the outer container is provided with self-locking tabs to prevent the bowl-like container from collapsing and returning to its knock-down, shipped condition after fully erected and filled with the food pouch.

Abstract: A sleeve slides over an erected and closed carton to maintain it in its closed position. The sleeve may be of paper or paperboard and includes an integral flap covering an underlying sleeve area. The flap and underlying area are preferably printed or decorated to form a greeting or gift card.

Abstract: A reclosable bag having front and back panels and an open end or mouth adaptable to be reclosabe. A non-resiliently deformable label or strip, such as a metal-foil strip, is bonded to one of the panels adjacent to the open end. The label is of sufficient width so that when the mouth end of the bag is folded upon itself, the bag will maintain the folded configuration. The label is adapted to be folded about its transverse axis to form a multi-layer rectangular structure when the mouth end of the bag is folded upon itself. The label has a U-shaped slit with the open end of the slit terminating at the transverse axis. When the label is folded about the axis, the segment of the label outlined by the U-shaped slit extends beyond the folded edge of the label and bag to form a tab. The tab is provided with an opening thereby permitting the bag to be hung on a rack.

Abstract: A paperboard cover adapted for being marginally secured to a popcorn container comprises circular and semicircular cut scores defining a lift tongue therebetween. The end part of the lift tongue is provided with an easy lift tab and communicates with a cutout area. The cutout area is covered by an easy lift protective flat piece that at least partially is glued to a surface portion of the cover.

Abstract: A paperboard cover adapted for being marginally secured to a container for prepackaged foods comprises an angular cut and circular and semi-circular cut scores defining a lift tongue. A pull-tab in the form of a pressure-sensitive adhesive label or of a precut paperboard tab covers the angular cut and has a portion thereof facing the tip of the lift tongue firmly secured thereto by the adhesive while the part thereof overlapping the angular cut is easy to lift.

Abstract: A paperboard cover adapted for being marginally secured to a container for prepackaged foods comprises circular and arched cut scores defining a pull tongue therebetween. The pull tongue at its free end defines an easy lift tab communicating with a cutout area between the circular and arched cut scores. A protective paperboard tab spans the cutout area and it partially glued to the upper surface of the cover.

Abstract: A carton provided with an integral, pivotable carrying handle on the top wall. The handle is a portion of a unitary blank of paperboard stock used to form the carton. When the carton is erected, the handle can be pivoted from a substantially flat stored position on the top wall to an upright use position for carrying the carton. The handle is formed from three overlapping panels after the blank is folded to provide a handle having superior strength.

Abstract: To reduce the chances of breakage at splices between rolls of plastic material to be printed or otherwise treated where the rolls are to be separated after treatment for rewinding on individual cores, a length of paper material is bonded to the trailing end of each roll of plastic material. The next roll of plastic material is spliced to the paper trailer to provide the continuous length to be treated. On the delivery side of the treatment station, successive rolls of plastic material are severed at the paper trailer to reduce the chances of breakage that might otherwise occur during attempts to separate the rolls at a plastic material splice.

Abstract: A carton provided with an integral, pivotable carrying handle on the top wall. The handle is die-cut in a blank of paperboard stock used to form the carton. When the carton is erected, the handle can be pivoted from a sustantially flat stored position on the top wall to an upright use position for carrying the carton.
