Abstract: A method is provided for producing a primary laminate including a tabstock in which a seal laminate including a foil layer and a top foam layer, a tabstock and a plastic film stock are fed to a laminating station. At the lamination station, a curtain of polymeric adhesive is extruded between the plastics film stock and the top face of the primary substrate, which is partly comprised of the top face of the tabstock and partly comprised of the top foam layer of the seal laminate. Use of primary laminates obtained by such a process to form seals for sealing a container, for food or drink stored at low temperatures, is also described.

Abstract: The invention relates to a reclosable packaging with a packaging body (12), with an edge component (14) surrounding a packaging opening (16) and which is irremovably connected to the packaging body (12), and also with a lid (20) which is held on the edge component (14) and closes the packaging opening (16), wherein the packaging body (12) is substantially formed by a flexible packaging body film (13) at least in one section (12a) accommodating the edge component (14), wherein the lid (20) is connected to the edge component (14) by means of a first detachable connection in the form of an adhesive bond or seal in the initially closed packaging state, and in a reclosed packaging state after a first opening is connected to the edge component (14) by means of a second detachable and restorable connection formed separately from the first connection.

Abstract: A server lid for a container with an integral tear strip tamper evident feature is presented. A tear strip for the tamper evident feature is molded as an adjunct to a base member which forms the closure. The tear strip is joined to the base by at least one frangible web, and hinges about the frangible web to overlie front edges of one or more flaps formed in the server lid. Ultrasonic welds connect the overlying tear strip to the flaps or adjacent the flaps for providing a tamper evident feature. The shape of the server lid provides stackability in that the base rim of the container will fit over the upper portion of the lid, including frangible webs to allow interfitting of one container bottom with the container closure of the next, to allow the containers to be stacked on a shelf without substantial danger of slipping or tipping.

Abstract: A closure for a container includes a base having an aperture therethrough, a membrane attached to the bottom of the base and adapted to be attached to the container to seal the opening, a pull tab positioned within the aperture and connected to the base around at least a portion of an inner periphery of the aperture by a frangible portion, and a cap connected to the base by a hinge. The base is adapted to be connected to the container such that the aperture is positioned over the opening. The pull tab is connected to the membrane, so that when a user pulls on the pull tab, the frangible portion breaks to allow removal of the pull tab to open the aperture, and removal of the pull tab causes the portion of the membrane to tear away to unseal the opening of the container. The cap is pivotable about the hinge between an open position and a closed position.

Abstract: A tamper-evident rigid plastic food container system wherein the outer periphery of the mating surfaces of the lid and tray are permanently bonded together after the food product has been placed in the tray, a set of perforated rows at an inner periphery, the interconnect of which needs to be torn into order to open the lid. Intentional, inadvertent or malicious ingress into the container can only be made by tearing at the perforations thereby evidencing the potential tampering and contamination of the packaging contents. The lid and tray edges may further include mechanical interference fits, including snap-fit grips that may be of the releasably lockable kind to permit sealing, release and re-sealing multiple times without deterioration in reliability, and which can further prevent or minimize leakage of liquid food product.

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: Disclosed is an opening device for a foil closure can be fitted to a container body. The device comprises a spout (4) with a removable disc (10) attached to a pull-ring (12). The disc (10) is secured to the spout (4) by means of a frangible region (30). A foil (8) is sealed to a raised land (34) on a base of the disc (10). The pull ring is mounted to the disc (10) by means of legs so that it applies a force on a peninsula (50) of the disc, thereby reducing the length of the arc over which an initial pulling force is dissipated when the initial tear is being initiated reducing the force required to tear the foil (8) by up to 40%.

Abstract: A resealable container and/or resealable container end for foods such as beverages. The end includes an opening and a pull-tab closure which includes a plug for sealing the opening. The closure may be fabricated from a thermoplastic coated foil.

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 peelable lid structure, particularly for use in the closing of food cans, has a tab which is folded over the center panel and secured in the folded position for processing of can contents and/or handling operations.

Abstract: A package for storing and shipping food products incorporates a multilayer film lid that includes a gas-impermeable exterior layer and a gas-permeable interior layer. The multilayer film lid is heat sealed to a flange of a tray upon which the food product is supported. The gas-impermeable layer may be delaminated from the gas-permeable layer when it is desired to expose the food to atmospheric gases. Separation of the gas-impermeable layer from the gas-permeable layer is facilitated by a film fracture feature included in the heat seal pattern adjacent a pull tab of the lid. The film fracture feature concentrates the separation forces exerted on the tab in a small area so that the gas-permeable layer of the lid readily breaks at the film fracture feature.
