Abstract: A container is thermoformed from a multilayer sheet, which includes a container body and a flange extending outward from a circumference of an opening of the container body. An end of the first layer extends over an edge of a peeled surface toward a bottom side on an outer end surface of the flange. When a lid is heat-sealed to the flange of the container, even if a seal resin is melted and flowed toward the end surface of the flange, since the edge of the peeled surface is covered with the end of the first layer, the seal resin will not adhere to the edge of the peeled surface.

Abstract: A container having an integrated bottom end closure subassembly. The container includes a top opening and bottom opening. The top opening is initially closed and sealed with a top membrane while the bottom opening is closed by the end closure subassembly. The subassembly includes an end cap and a bottom membrane. The subassembly is configured so that positioning the end cap onto the container to close the bottom opening positions the bottom membrane near the container. The bottom membrane may be sealed to the container. Once the bottom membrane is sealed to the container, the end cap may be removed from the container independently from the bottom membrane. The end cap provides protection to the bottom membrane during shipping and handling and then is used by the consumer to reclose the top opening once the top membrane is removed.

Abstract: An element which is punched out in a cover shape for sealing of containers, includes two plies with at least one opening aid which is integrated within these plies, the ply (3) located in the direction of the container having a plastic layer which is provided with perforations or scoring. The layers of the sealing element are cemented by a peelable adhesive layer, the opening aid and the ply which has the plastic layer being free of adhesive in the area of its perforations or scoring. The sealing element enables not only facilitated sealing of food containers, such as microwave containers, since mutual displacement or slippage of the individual plies due to the adhesive layer is prevented, but that any type of penetration of adhesive into the food container, thus into the food, is prevented in any case by the peelability of the adhesive.

Abstract: A packaging carton box structure includes a first sheet and a second sheet, and a pre-tearing portion is disposed on a first side plate of the first sheet. After the first sheet and the second sheet are bent, an object is packaged, and then, after the packaged object is placed on a placement plane, the pre-tearing portion is torn, so as to take out the object along a direction parallel to the placement plane, which is time-saving and labor-saving, and further prevents the object from falling off to result in damages when being taken out.

Abstract: A composite container of paperboard has a polymeric film barrier layer on the inner surface thereof. A rolled bead is formed at a top end of the container and a membrane closure is bonded to the bead by a first heat seal material on the bead and a second heat seal material on the membrane. The heat seal materials preferably comprise ethylene acid copolymer such as methacrylic acid or acrylic acid, partially neutralized with zinc or sodium ions. A primer layer is disposed between the heat seal material on the bead and the polymer barrier layer of the container. The primer provides a high z-direction bond strength but is designed to fail in a shear tearing mode when peeling the membrane from the bead, such that the heat seal material on the bead is detached from the bead and remains attached to the membrane. The primer prevents tearing of the polymer barrier layer of the container.

Abstract: A closure for sealing an opening of a tubular container is disclosed, the closure having a paperboard central panel with a plurality of secondary panels extending angularly therefrom forming a surface around the perimeter of the central panel. A plastic skirt is adhered around the perimeter of the central panel and to one side of the secondary panels opposite the surface to reinforce it. A metal foil layer is adhered to the surface, the foil having a side facing the sidewall of the container with a heat-activated adhesive layer thereon. The closure is positioned on the container with the central panel in registration with the opening and the heat-activated adhesive layer engaging the sidewall of the container. The seal between the closure and the container is effected by subjecting the container to an electromagnetic induction field, whereby eddy currents induced in the metal foil by the field cause the heat-activated adhesive to form a bond between the container sidewall and the secondary panels.

Abstract: A pressure-sensitive closure mechanism for a folded carton incorporates a pressure-sensitive tape having adhesive on one surface thereof disposed on a one side of a hinged lid panel, with the adhesive exposed through an opening in the lid panel and releasably engaging an outer surface of a flap-receiving panel. The hinged lid panel is formed by folding an inner lid panel over an outer lid panel. Both lid panels have openings. The pressure-sensitive tape is disposed between the two lid panels. When the lid is closed over the opening in the carton, the user applies pressure with his finger to the backside (non-adhesive) side of the pressure-sensitive tape. The pressure pushes the tape against flap-receiving panel of the carton. Repeated closings and openings are possible.
